Description

Technical Field

[0001] The present invention relates to a pneumatic fluidization device for a hopper and its operation mode Background Art

[0002] The currently common hopper gasification system is shown in the appendix Figure 1 and mainly consists of the following parts: a fabric / sintered porous gasification plate 11, a gasification air supply pipe 12 The existing hopper gasification system has the following problems: 1) For materials with poor fluidity, the fluidization effect is poor.

[0003] 2) When multiple hoppers are fluidized, there is an uneven fluidization situation. Summary of the Invention

[0004] The purpose of the present invention is to solve the above problems existing in the existing hopper gasification system and provide a new type of pneumatic fluidization device for a hopper.

[0005] The improved pneumatic fluidization device for a hopper is shown in the appendix Figure 2 and mainly consists of the following parts: a housing 21, a flat-headed push rod 22, a return spring 23, and a pulse air inlet valve 24 When the coil of the pulse air inlet valve 24 is energized, compressed air enters from the air inlet below the pulse air inlet valve 24 and pushes the flat-headed push rod 22 forward; when the pulse air inlet valve 24 is de-energized, the compressed air is cut off, and the return spring 23 pulls the flat-headed push rod 22 back to its original position.

[0006] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects: 1) The mechanical action of the flat-headed push rod 22 can achieve a better fluidization effect for materials with poor fluidity.

[0007] 2) The air consumption is relatively small.

[0008] 3) The impact is small and has no influence on the hopper structure.

[0009] The pneumatic fluidization device for a hopper of the present invention solves the problems existing in the existing hopper gasification system, provides a new type of gasification device with good gasification effect and small air consumption, and has high popularization value.

[0010] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.

Claims

1. A hopper pneumatic fluidization device, comprising: Housing, flat head push rod, return spring, pulse intake valve.

2. The hopper pneumatic fluidization device according to claim 1, characterized in that When the pulse intake valve coil is energized, compressed air enters from the air inlet below the pulse intake valve, pushing the flat head push rod forward. When the pulse intake valve is de-energized, the compressed air is cut off, and the return spring pulls the flat head push rod back to its original position.
