The defeated powder process of the utility model is following:
1) opens inlet valve, let an amount of powder enter into the powder storehouse, close inlet valve and bleeder valve then;
2) in the pressure storehouse, import high pressure gas, make pressure storehouse internal gas pressure raise, high pressure gas see through gasifier bed can enter into inside, powder storehouse equably, and can blow the powder that is positioned at bottom, powder storehouse loose;
3) treat that powder storehouse in-to-in air pressure arrives preset level after, open bleeder valve, then powder will enter into conveying pipeline from discharging opening with gas, and carry outward through bleeder valve;
4) in the process that powder is carried outward, keep to pressure storehouse input high pressure gas, the powder in the powder storehouse has quantitatively been carried or has been carried fully, stops the high pressure gas input, accomplishes a working cycle;
5) according to process 1)～4) cycle event.
Because what adopt is gas negative pressure powder feeding principle, and powder can be at first by pineization, so the utility model can provide farther and higher powder fed distance under lower energy consumption before being transferred.
For further strengthening the function and the performance of the utility model, can do following the improvement to the utility model:
Gasifier bed is infundibulate, and the center and the discharging opening of infundibulate gasifier bed are relative, makes that powder can be constantly near discharging opening; Distance between discharging opening and the gasifier bed is preferably between 50mm～80mm;
Level detector is set, in order to detect the height of powder in the powder storehouse on pressure volume pot;
BARO sensor is set, in order to detect the air pressure in powder storehouse on pressure volume pot;
The air pressure safety valve is set on pressure volume pot, too high in order to prevent the air pressure in the pressure volume pot;
Outer bottom at pressure volume pot is provided with LOAD CELLS, in order to calculate the weight of powder in the powder storehouse;
Freeing pipe is set on pressure volume pot, and an end of freeing pipe is communicated with the powder storehouse, and the other end of freeing pipe is communicated with the delivery pipe of bleeder valve, on freeing pipe, is provided with aie escape valve and boiler check valve.Can realize pressure release thus, and utilize the pressure of being released to rest on powder discharge in the delivery duct, prevent that delivery duct is blocked pressure volume pot.
In addition, owing to need charge into high pressure gas in the pressure volume pot, so the inlet valve of the utility model etc. should be able to satisfy the air-tightness requirement under the corresponding high pressure.
The utlity model has following advantage: 1) energy consumption is low, and the screw-rod air compressor of configuration 45KW can be realized 1000 meters of levels or vertical 200 meters fed distance; 2) airtight operation is pollution-free; 3) floor area is little; 4) adopt ducting, landline can be formulated flexibly; 5) adopt PLC and gas control interlock mode can realize automation control; 6) can adopt electronic weighing balance to solve the difficult problem of weighing of bulk powder.
