[0002] Industrial production often involves the transportation of powdered materials. The existing pneumatic chute for powder transportation is mainly composed of three parts. They are the upper half chute, the air permeable plate and the lower half chute. Among them, the air permeable plates of the pneumatic chute in the prior art are all arranged horizontally, dividing the chute into two parts, namely the "material chamber" and the "air chamber".

[0003] When the pneumatic chute is conveying powder, large particles of powder tend to settle downwards and on the air permeable plate. There is a lack of cleaning measures for the deposited powder. After a long period of accumulation, it will affect the air intake of the air permeable plate. Therefore, improvements are needed. Utility Model Content

[0004] The technical problem to be solved by the utility model is that in the process of conveying powder in the pneumatic chute in the prior art, large particles of powder are easily deposited on the air permeable plate, and there is a lack of cleaning measures for the deposited powder.

[0006] Preferably, the air permeable plate is inclined toward the collecting pipe and has openings between the bottoms of the air permeable plates. The sealing plate can just seal the openings between the air permeable plates. The air permeable plate forms a V-shaped air permeable plate when the bottom is sealed. Even if the large particles of powder in the material chamber settle, they will settle at the bottom of the air permeable plate. By opening the sealing plate, the powder can be leaked into the collecting pipe for centralized treatment.

[0007] Preferably, a blower is provided at one end of the collecting pipe, and the large-particle powder collected in the collecting pipe can be blown out by the blower.

[0008] Preferably, the collecting pipe is arranged in a circular tube shape and the notch on the top is larger than the end opening of the air permeable plate.

[0010] The utility model adopts the above structure to achieve the following beneficial effects:

[0011] The utility model can seal the lower end of the air permeable plate by arranging a sealing device, so that large-particle powder in the material chamber is deposited at the lowermost end of the air permeable plate. When the sealing plate is opened, the deposited powder can fall into the collecting pipe, and the deposited powder can be blown out by a hair dryer to achieve the purpose of cleaning.

[0019] like Figure 1 and 3 The blocking device 9 includes an electric push rod 10, which is arranged at the inner bottom center of the collecting pipe 6. A blocking plate 11 is arranged at the output end of the electric push rod 10. The vertical section of the blocking plate 11 is arranged in the shape of an isosceles triangle. When the blocking plate 11 is opened, the deposited powder can smoothly fall into the collecting pipe 6. The air permeable plate 7 is inclined toward the collecting pipe 6 and there are openings between the bottoms of the air permeable plates 7. The blocking plate 11 can just block the openings between the air permeable plates 7. The air permeable plate 7 forms a V-shaped air permeable plate 7 in the bottom blocking state.

The large particles of powder in the material chamber 1 will settle to the bottom of the air permeable plate 7.

[0021] When it is necessary to clean up the deposited powder at the bottom of the air permeable plate 7, by starting the electric push rod 10, the sealing plate 11 moves downward, and the powder passes through the opening at the bottom of the air permeable plate 7 and through the gap 8 into the collecting pipe 6, and then the gap 8 is closed again. Through the hair dryer 12, air can be blown into the collecting pipe 6, and the collected powder will be discharged from the other end of the collecting pipe 6, thereby achieving the purpose of cleaning the deposited powder on the air permeable plate 7.
