氣力輸送又被稱為氣體流動(dòng)輸送，是運(yùn)用氣體機(jī)械能將物料在封閉管路中順著氣體流動(dòng)方位輸送的一種技術(shù)性。氣力輸送系統(tǒng)可以有效地運(yùn)用車間室內(nèi)空間，而且耗能低，噪聲小，還不容易對(duì)自然環(huán)境產(chǎn)生危害。今日咱們就來了解一下氣力輸送中央供料系統(tǒng)由什么設(shè)備構(gòu)成?

　　氣力輸送中央供料系統(tǒng)關(guān)鍵有送料系統(tǒng)、氣動(dòng)閥門系統(tǒng)、輸送管道系統(tǒng)、除灰系統(tǒng)、料斗系統(tǒng)及其操縱系統(tǒng)構(gòu)成，可以完成輸送、計(jì)量檢定、復(fù)混肥、干躁、除灰等作用，在其中，不一樣的一部分充分發(fā)揮著不一樣的功效:

　　送料系統(tǒng):

　　供料系統(tǒng)關(guān)鍵的功效便是提供物料，讓其在密閉的系統(tǒng)中完成輸送，對(duì)于不一樣的物料輸送規(guī)定,可以選用差異的送料系統(tǒng)。翔瑞的供料系統(tǒng)有旋轉(zhuǎn)供料器、磁力泵、倉式泵、噴嘴流量計(jì)等設(shè)備。

　　管道系統(tǒng):

　　管路系統(tǒng)是完成送料系統(tǒng)與氣力輸送系統(tǒng)聯(lián)接的管道，關(guān)鍵目標(biāo)是完成物料的長距離輸送。當(dāng)物料對(duì)氣動(dòng)閥門有沽凈規(guī)定的情況下，我們可以在管道系統(tǒng)中**如空氣過濾網(wǎng)、除灰設(shè)備等氣動(dòng)閥門凈化處理設(shè)備。管路的選材與設(shè)計(jì)方案會(huì)對(duì)物料的輸送高效率導(dǎo)致立即的危害，因而在制定前期就需要更加考慮到。

　　備料系統(tǒng):

　　收料系統(tǒng)*首要的設(shè)備是料斗，它經(jīng)常是角錐或是是囫錐狀的結(jié)構(gòu)，可以具有臨時(shí)儲(chǔ)存物料和推廣物料的功效，料斗設(shè)計(jì)方案必須考慮到不一樣物料在儲(chǔ)存及倒料全過程中的問題和物料的流動(dòng)性方式。翔瑞的料斗有存儲(chǔ)料斗、作用力復(fù)混肥料斗、減壓蒸餾倉、制冷倉、正中間拌和倉等。

　　除灰系統(tǒng):

　　除塵系統(tǒng)關(guān)聯(lián)到全部氣力輸送系統(tǒng)的排出是不是能實(shí)現(xiàn)環(huán)境保護(hù)規(guī)定，提議每位老總依據(jù)物料不一樣的料性，不同的比例，來實(shí)現(xiàn)挑選，要不然非常容易由于設(shè)計(jì)方案不配對(duì)導(dǎo)致系統(tǒng)排出不合格，因此應(yīng)當(dāng)選擇專業(yè)生產(chǎn)廠家，可依據(jù)具體需要挑選恰當(dāng)合適的除灰設(shè)備。

　　操縱系統(tǒng):

　　控制系統(tǒng)主要是完成對(duì)中央供料系統(tǒng)的調(diào)整操縱，選用可編式控制板實(shí)現(xiàn)操縱，可以配自動(dòng)控制系統(tǒng)電機(jī)控制系統(tǒng)，完成全部系統(tǒng)沒有人操縱及相互配合PLC白動(dòng)操縱。根據(jù)系統(tǒng)來集中控制系統(tǒng)系統(tǒng)的除灰、輸送.警報(bào)、常見故障泊車等工作中，可以更便捷更可靠地對(duì)開展實(shí)時(shí)控制。

　　三、密閉式自然環(huán)境

　　輸送線路上選用密閉式管路開展輸送，安全系數(shù)高，著火和發(fā)生爆炸的風(fēng)險(xiǎn)性小，而且可以維持工業(yè)區(qū)清潔衛(wèi)生，降低煙塵散出產(chǎn)生的空氣污染。

　　四、可完成遠(yuǎn)距離大空間輸送

　　氣力輸送比較遠(yuǎn)可達(dá)一公里以上，工作能力每鐘頭可達(dá)上百噸/小時(shí)，沿路僅有管路，布局靈便，不占室內(nèi)空間，實(shí)際操作檢修簡易。

　　五、易完成自動(dòng)化技術(shù)

　　氣力輸送中央供料系統(tǒng)中選用的羅茨機(jī)械泵(羅茨風(fēng)機(jī))、總流量調(diào)節(jié)器和信號(hào)接收器等設(shè)備的實(shí)際操作與液體設(shè)備的實(shí)際操作相似之處非常大。因而可以選用同一個(gè)核心控制面板實(shí)際操作，易完成自動(dòng)化生產(chǎn)。

　　氣力輸送相對(duì)性于機(jī)械設(shè)備輸送高效率要高，而且合理性高、布局靈便。氣力輸送技術(shù)性并沒有統(tǒng)一的規(guī)范，關(guān)鍵是設(shè)計(jì)師工作經(jīng)驗(yàn)累積的需求較高。氣力輸送設(shè)備防污抗氧化效果非常的好;有益于公司完成專業(yè)化和自動(dòng)化技術(shù)，可緩解勞動(dòng)效率，節(jié)約人力資源，減少人力成本，降低空氣污染;在輸送全過程中，可以一起開展多種多樣加工工藝實(shí)際操作，如混和、破碎、篩分、干躁、制冷;避免物料返潮、環(huán)境污染或滲入臟物等優(yōu)勢(shì)，因此在鑄造、冶金工業(yè)、化工廠、裝飾建材、糧油加工等機(jī)構(gòu)都獲得運(yùn)用。

　　它的具體不足之處是驅(qū)動(dòng)力耗費(fèi)比較大;設(shè)備(主要是分離設(shè)備通道)和管路(主要是彎管)損壞較快，假如設(shè)計(jì)方案、工程施工或運(yùn)行不合理，則很容易導(dǎo)致物料堆積，以至阻塞，使輸送終斷;不適合輸送環(huán)境濕度大、粘性大或易碎的物料等。

　　氣力輸送設(shè)備一般由受加料器(如喉嚨、真空吸盤、發(fā)送器等)、輸送管、風(fēng)道、分離設(shè)備(常見的有容量式和旋風(fēng)式二種)、鎖氣器(常見的有翻平板式和管式二種，既可做為喂加料器，又可做為卸料器)、除塵設(shè)備和離心風(fēng)機(jī)(如離心式風(fēng)機(jī)、羅茨風(fēng)機(jī)、水環(huán)式真空泵、空氣壓縮機(jī)等)等設(shè)備和構(gòu)件構(gòu)成。

　　Pneumatic conveying, also known as gas flow conveying, is a kind of technology that uses gas mechanical energy to convey materials along the direction of gas flow in a closed pipeline. The pneumatic conveying system can effectively use the indoor space of the workshop, and has low energy consumption, low noise and is not easy to harm the natural environment. Today, let's take a look at what equipment constitutes the pneumatic conveying central feeding system?

　　The central feeding system of pneumatic conveying is composed of feeding system, pneumatic valve system, conveying pipeline system, ash removal system, hopper system and its control system, which can complete the functions of conveying, metrological verification, compound fertilizer, dryness and ash removal. Among them, different parts give full play to different effects:

　　Feeding system:

　　The key function of the feeding system is to provide materials to complete the transportation in a closed system. For different material transportation regulations, different feeding systems can be selected. Xiangrui's feeding system includes rotating feeder, magnetic pump, bin pump, nozzle flowmeter and other equipment.

　　Piping system:

　　The pipeline system is the pipeline connecting the feeding system and the pneumatic conveying system, and the key goal is to complete the long-distance transportation of materials. When there are regulations on the net selling of pneumatic valves for materials, we can improve the purification treatment equipment of pneumatic valves such as air filter screen and ash removal equipment in the pipeline system. The material selection and design scheme of pipeline will cause immediate harm to the high efficiency of material transportation, so it needs to be taken into account in the early stage of formulation.

　　Material preparation system:

　　The most important equipment of the receiving system is the hopper. It is often a pyramid or a whole cone structure, which can temporarily store and promote materials. The hopper design scheme must take into account the problems of different materials in the whole process of storage and dumping and the fluidity of materials. Xiangrui's hoppers include storage hopper, acting compound fertilizer hopper, decompression distillation bin, refrigeration bin, central mixing bin, etc.

　　Ash handling system:

　　The dust removal system is related to whether the discharge of all pneumatic conveying systems can realize the provisions of environmental protection. It is suggested that each boss choose according to the different material properties and different proportions of materials. Otherwise, it is very easy to cause unqualified system discharge due to mismatched design schemes. Therefore, professional manufacturers should be selected, and appropriate ash removal equipment can be selected according to specific needs.

　　Control system:

　　The control system mainly completes the adjustment and operation of the central feeding system, selects the programmable control board to realize the operation, and can be equipped with the automatic control system and motor control system to complete the unmanned operation of all systems and cooperate with each other in PLC white operation. Centralized control of ash removal and transportation according to the system In alarm, common fault parking and other work, real-time control can be carried out more conveniently and reliably.

　　Advantages of pneumatic conveying central feeding system

　　1、 Flexible use of indoor space

　　Pneumatic conveying equipment is simple, which can effectively and conveniently use the indoor space of the workshop, and rely on class II pressure vessels to avoid obstacles such as large and medium-sized equipment, houses and buildings. Moreover, it can complete the centralized transportation of more materials, or the decentralized transportation from one point to many points.

　　2、 Wide application range

　　The pneumatic conveying system is suitable for the continuous transportation of small particle powder materials. At the same time, it is also suitable for and intermittent transportation of many particle materials from bulk oil tank trucks, railway trucks, sea ships and other equipment to storage warehouses.

　　3、 Closed natural environment

　　The closed pipeline is selected for transmission on the transmission line, which has high safety factor and low risk of fire and explosion. In addition, it can maintain the cleanliness of the industrial area and reduce the air pollution caused by the emission of smoke and dust.

　　4、 It can complete long-distance and large space transportation

　　Pneumatic conveying is far away, up to more than one kilometer, and the working capacity can reach hundreds of tons / hour. There are only pipelines along the road, the layout is convenient, does not occupy indoor space, and the actual operation and maintenance are simple.

　　5、 Easy to complete automation technology

　　The actual operation of roots mechanical pump (roots blower), total flow regulator and signal receiver selected in the central feeding system of pneumatic conveying is very similar to that of liquid equipment. Therefore, the same core control panel can be selected for actual operation, which is easy to complete automatic production.

　　Compared with mechanical equipment, pneumatic conveying has high efficiency, high rationality and convenient layout. There is no unified specification for pneumatic conveying technology. The key is the high demand for designers' accumulated work experience. The antifouling and antioxidant effect of pneumatic conveying equipment is very good; It is beneficial for the company to complete specialization and automation technology, alleviate labor efficiency, save human resources, reduce labor costs and reduce air pollution; In the whole process of transportation, various processing processes can be carried out together, such as mixing, crushing, screening, drying and refrigeration; It has the advantages of avoiding material moisture return, environmental pollution or infiltration of dirt. Therefore, it has been used in foundry, metallurgical industry, chemical plant, decorative building materials, grain and oil processing and other institutions.

　　Its specific deficiency is that the driving force is relatively expensive; The equipment (mainly separation equipment channel) and pipeline (mainly elbow) are damaged quickly. If the design scheme, engineering construction or operation are unreasonable, it is easy to lead to material accumulation, even blockage and final interruption of transportation; It is not suitable for conveying materials with high humidity, high viscosity or fragile.

　　Pneumatic conveying equipment is generally composed of feeder (such as throat, vacuum suction cup, transmitter, etc.), conveying pipe, air duct, separation equipment (common capacity type and cyclone type), air lock (common turnover plate type and pipe type, which can be used as both feeder and discharger), dust removal equipment, centrifugal fan (such as centrifugal fan, Roots fan, water ring vacuum pump, air compressor, etc.).

　　Operation steps of pneumatic conveying central feeding equipment

　　Before opening the equipment, check whether the equipment is filled with oil, whether all parts of the equipment are intact, whether the forward and reverse rotation of roots centrifugal fan and rotary feeder, and whether the conveying pipeline is smooth.

　　Opening method: first open the roots centrifugal fan or roots pump, observe the working pressure of the air pressure gauge at the inlet and outlet of the centrifugal fan, and the working pressure is almost zero when the pipeline is unobstructed; Then open the first rotary feeder, and finally gradually open the upper manual plug valve. With the opening of the gate valve, the material will fall into the rotary feeder and then into the conveying pipeline, and the barometer will fluctuate. According to the fluidity of materials and the indication of barometer, the opening degree of manual valve can be adjusted to control the blanking amount. Observe the change of barometer anytime and anywhere.

　　For the conveying route of two feeders, after the material conveying of the first rotary feeder is completed, turn off the first rotary feeder. After 1-2min, the material conveying in the pipeline is completed, and then turn on the second rotary feeder to operate successively.

　　Termination method: first turn off the manual gate valve (if the equipment is terminated in a short time, it is not necessary to turn off the manual gate valve), then turn off the rotary feeder, observe the air pressure gauge at the inlet and outlet of the centrifugal fan, and then turn off the Roots fan when the gas pressure is the working pressure of the civil aviation air duct (the spacing is about I min).

　　Pneumatic conveying can save energy and control costs, and help companies maximize profits. It is the inevitable trend of every company. There are many forms of pneumatic conveying. Selecting appropriate pneumatic conveying methods and equipment is an important way to ensure the rationality of the company's production process and the high efficiency of conveying.
