2. In the fluidization pressurization stage, the air inlet valve is automatically opened, compressed air enters the fluidization chamber at the bottom of the pump body, and passes through the fluidization disc after being diffused, and when the materials are fully fluidized, the air pressure in the pump body rises.
3. In the conveying stage, when the pressure in the pump body reaches a certain value, the pressure sensor sends a signal, the conveying air valve and the discharge valve are automatically opened, the fluidization of the materials on the fluidization plate is enhanced, the conveying is started, the materials in the pump are gradually reduced, and the materials on the fluidization plate are always in a state of conveying while fluidizing.

In the process that the bin level gauge 2 is moved and put outwards, high temperature and high pressure in the bin body 1 can be put outwards into a dustproof mechanism, dust and materials and the like which are filtered and intercepted by the first filtering layer 204 are scattered outside through the first filtering layer 204, when the air outlet 202 is blocked by the sealing cover 11, the dust and materials can be intensively sucked into a collecting hopper through the material suction mechanism, specifically, the exhaust fan 301 is started, the first filtering layer 302, the upper cover 305, the second filtering layer 304, the lower hopper 306, the collecting pipe 307 and the second filtering layer 303 sequentially carry out pneumatic suction on the two dustproof half covers 201, dust and materials are blocked by the filtering layer when the second filtering layer 303 and the collecting pipe 307 enter the space between the second filtering layer 304 and the lower hopper 306, the dust and the materials fall into the space between the lower hopper 306 and the collecting pipe 307 to be collected, when the space between the lower hopper 306 and the collecting pipe 307 needs cleaning, the second filtering layer 303, the mounting piece 308 and the lower hopper 306 are detached, and the collecting pipe 307 are detached from the mounting opening to be cleaned.
In this embodiment, the level gauge 2 moves at three fixed-point positions:
A. the working position is as follows: the sealing baffle cover 6 covers the pressure release channel 5, and at the moment, the sealing baffle cover 6 and the baffle ring 4 are matched to have a sealing effect on the inside of the bin body 1, so that the bin pump can normally perform a series of works.
B. Decompression suction cleaning position: the protection clamping ring 7 moves into the two dustproof half covers 201, the plugging cover 9 still plugs the outlet 203 in the outlets 203 of the two dustproof half covers 201, the two dustproof half covers 201 are limited to be in a surrounding shape by the limiting piece 205, and at the moment, only the air outlet 202 of the dustproof half cover 201 is required to be plugged, so that dust and materials can be removed from the dustproof mechanism through the material suction mechanism.
C. Full out position: as shown in fig. 18, the limit of the two dust-proof half covers 201 by the limit piece 205 is released, and the two dust-proof half covers 201 are opened, so that the level gauge 2 can continue to move outwards until the level gauge 2 is completely moved out to the outside, and at this time, the whole inspection, maintenance, manual cleaning, disassembly and replacement and other work can be performed on the level gauge 2.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
