A mobile powder injection process

Abstract

The invention provides a movable powder injection system and a process method thereof. The movable powder injection system comprises a sending tank, a receiving tank and a dust collector, wherein the sending tank, receiving tank and the dust collector to form a closed loop system; the dust collector is directly arranged above the sending tank; the receiving tank is connected with the sending tank through a discharge pipe; the receiving tank is connected to the dust collector through a return pipe; a vacuum generator is arranged in the dust collector. The movable powder injection system has the beneficial effects that the dust collector is directly connected with the sending tank rather than being arranged on the receiving tank, so that one set of feeding system can be matched with multiple sets of receiving devices, and the cost of dust collector is saved; moreover, residual powder intercepted by the dust collector is sent once again through the sending tank. The process can be performed circularly.

Description

technical field [0001] The invention relates to a mobile powder injection process method. Background technique [0002] At present, in the powder filling and conveying process, the pneumatic conveying sending tank filling system is widely used. The powder delivery tank filling system of the prior art is as figure 1 As shown, the implementation process is: (1) The sending tank 1'valve 7' is opened, and the powder enters the sending tank from the feeding port 4' to the set value; (2) The sending tank moves 1' to the receiving tank 2 ’ next to it, use the delivery pipe 10’ to connect to the receiving tank 2’ through the connector 11’; (3) the valve 7’, the valve 9’ are closed, the valve 6’, the valve 8’ are opened, and the compressed air enters the tank for fluidization and When the pressure reaches the set pressure, the valve 9' is opened, and the powder material starts to be transported into the receiving tank 2'. At this time, the exhaust valve 12' is opened, and most of t...

Problems solved by technology

For the working condition where the dust collector 3' can only be installed on the side with complex stirring internals, the exhaust pipe 13' is long and has a certain angle, especially for light powders such as carbon black and carbon powder, there will be It remains in the exhaust pipe 13' and the inner wall of the dust collector 3'. At the same time, the positive pressure gas pulse cleaning of the dust collector 3' will cause pressure fluctuations in the receiving tank 2' to generate a lot of dust and adhere to the inner wall, resulting in inaccurate measurement. Accurate, polluted materials or even polluted and damaged mixing mechanism will have a very adverse effect on production
