常見的氣力輸送設備如何安裝？

How to install common pneumatic conveying equipment?

1、一般情況下，料封泵裝在料倉庫底比較合適，落料順暢。如果放不在庫底，置于旁邊亦可。但落料管斜角≥45°。如果裝在電除塵落灰斗下部，可以一斗一泵，亦可兩斗兩斜管一泵;特殊情況亦可四斗四斜管插入一臺料封泵中，但所有落灰斜管的斜度均應≥45°。

1. Generally, it is appropriate to install the material seal pump at the bottom of the material warehouse, and the material can be discharged smoothly. If it is not placed at the bottom of the warehouse, it can also be placed next to it. However, the inclined angle of the blanking pipe is ≥ 45 °. If it is installed at the lower part of the electrostatic precipitator ash hopper, it can be one bucket with one pump, or two buckets with two inclined pipes with one pump; Under special circumstances, four buckets and four inclined pipes can also be inserted into a material sealing pump, but the inclination of all ash falling inclined pipes shall be ≥ 45 °.

2、料封泵一般置于堅硬的水平地面上即可，無需打基礎安裝地腳螺栓，當風管,出料管連接好以后，即可投運。但要求進風管與泵管連接時應安裝一個撓性節頭。

2. Generally, the material seal pump can be placed on a hard horizontal ground without foundation and foundation bolts. It can be put into operation after the air duct and discharge pipe are connected. However, a flexible joint shall be installed when the air inlet pipe is connected with the pump pipe.

3、料封泵的總高(包括料封泵灰斗)一般為3.5-4.5m，根據現場實際情況亦可適當變動。

3. The total height of the material seal pump (including the ash hopper of the material seal pump) is generally 3.5-4.5m, which can be appropriately changed according to the actual situation on site.

4、料封泵放置出口方向，可根據現場情況而定，一般超向灰庫所在位置的方向為宜，或根據管路的走向而定。

4. The outlet direction of the material seal pump can be determined according to the site conditions. Generally, it is appropriate to go beyond the direction where the ash silo is located, or according to the direction of the pipeline.

5、本裝置要求庫頂收塵器的氣體散放量應大于料封泵送料帶風總量。勿使庫內出現正壓情況，以免影響輸灰系統工作。

5. The device requires that the gas emission amount of the dust collector on the top of the silo should be greater than the total amount of air carried by the material seal pump. Do not cause positive pressure in the silo, so as not to affect the operation of the ash conveying system.

6、要求氣源、料封泵、輸灰管全系統密封良好，漏風率小于 0.2%。

6. The air source, material seal pump and ash conveying pipe shall be well sealed, and the air leakage rate shall be less than 0.2%.

氣力輸送

Pneumatic conveying

氣動式真空上料機即是利用壓縮空氣通過真空發生器產生高真空實現對物料的輸送，不需要機械式真空泵，具有結構簡單、體積小、免維修、噪音低、控制方便、消除物料靜電和符合GMP要求等優點。真空發生器產生的高真空，使被輸送的物料杜絕了分層現象，保證了混合物料成分的均一性，是壓片機、膠囊填充機、干法制粒機、包裝機、粉碎機、振動篩等機械自動上料的選設備。 當壓縮空氣供給真空發生器時，真空發生器就產生負壓形成真空氣流，物料被吸入吸料咀，形成物氣流，經過吸料管到達上料機的料倉內。過濾器把物料與空氣完全分離，當物料裝滿料倉時，控制器會自動切斷氣源，真空發生器停止工作，同時料倉門自動開啟，物料落到設備的料斗中。與此同時，壓縮空氣通過脈沖反吹閥自動清洗過濾器。等到時間到或料位傳感器發出上料信號時，自動啟動上料機。

The pneumatic vacuum feeder uses compressed air to generate high vacuum through the vacuum generator to realize the delivery of materials. It does not need a mechanical vacuum pump. It has the advantages of simple structure, small volume, maintenance free, low noise, convenient control, elimination of material static electricity and compliance with GMP requirements. The high vacuum generated by the vacuum generator eliminates the stratification of the conveyed materials and ensures the homogeneity of the components of the mixed materials. It is a sorting equipment for automatic mechanical feeding, such as tablet press, capsule filling machine, dry granulation machine, packaging machine, crusher, vibrating screen, etc. When the compressed air is supplied to the vacuum generator, the vacuum generator will generate negative pressure to form a vacuum air flow. The materials are sucked into the suction nozzle to form an air flow, which will reach the silo of the feeding machine through the suction pipe. The filter completely separates the material from the air. When the material is full of the silo, the controller will automatically cut off the air source, the vacuum generator will stop working, the silo door will automatically open, and the material will fall into the hopper of the equipment. At the same time, the compressed air automatically cleans the filter through the pulse back blowing valve. When the time is up or the material level sensor sends the feeding signal, the feeding machine will be started automatically.
