Description

Technical Field

[0001] This invention relates to a dust suppression device, and more particularly to a dust suppression device for use in a straw feed crushing workshop. Background Technology

[0002] Adding dry straw to feed as a component is cost-effective and nutritious. The production of straw feed requires first crushing the dry straw before mixing it with grains and additives and then pelleting. Crushing the dry straw generates a large amount of dust, which contains both dust and dry straw particles. During dust suppression in the straw crushing workshop, because dust and dry straw particles are relatively light, many of these particles are adsorbed into the dust suppression device. This causes the device to absorb dust and dry straw particles too quickly and excessively, easily clogging the dust collector bags and rendering the dust suppression system ineffective. This necessitates repeatedly shutting down the dust suppression device to clear the blockage, significantly reducing its efficiency. Furthermore, the dry straw particles adhering to the dust collector bags are mixed with dust, making it impossible to effectively recover the adhering dry straw particles, thus wasting resources. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, this invention discloses a dust suppression device for use in straw feed crushing workshops. By adding a turntable to the dust suction pipe, and using the funnel-shaped expansion on the turntable in conjunction with the screen, large particles of dry straw in the dust are blocked and rotated into the lifting chamber, and then blown out and collected by a blower, thus achieving the purpose of effectively recycling large particles of dry straw and improving environmental protection.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A dust suppression device for use in a straw feed crushing workshop includes a semi-circular shell, a lifting bin, and a turntable. The semi-circular shell includes a semi-circular plate, the shape of which is slightly larger than half a circle. A perforation is provided in the middle of the arc edge of the semi-circular plate, and a through-hole is provided at the center of the semi-circular plate. Two semi-circular plates are arranged horizontally at intervals. An arc-shaped sidewall plate is provided between the arc edges of the two semi-circular plates.

[0031] Combined with appendix Figures 1-10The dust suppression device for use in a straw feed crushing workshop includes a semi-circular shell 4, a lifting bin 6, and a turntable 14.

A reducer 26 is provided between the motor 27 and the rotating shaft 21. The remaining part of the turntable 14 is placed in the lifting chamber 25. In the lifting chamber 25, there is a semicircular arc plate 31 whose upper end is in close contact with the lower arc edge of the turntable 14 located in the lifting chamber 25, and whose lower end is located above the bottom of the lifting chamber 25 and whose two straight edges are fixed to the side wall of the lifting chamber 25 respectively. A filter screen 36 is provided between the lower end of the semicircular arc plate 31 and the side wall of the lifting chamber 25. A blower 30 that blows upward is provided in the middle of the inner arc of the semicircular arc plate 31.A semi-conical hopper 7 is located at the lower end of the lifting hopper 6. A storage hopper 28 is located at the bottom of the semi-conical hopper 7. A semi-conical cavity 32, penetrating the lifting chamber 25, is located inside the semi-conical hopper 7. A storage chamber 33, penetrating the semi-conical cavity 32, is located inside the storage hopper 28. The lower end of the storage hopper 28 is flush with the lower end of the filter cylinder 40. A door B29 is located at the lower end of the side wall of the storage hopper 28. Within the lifting chamber 25, on opposite sides of the straight edge of the semi-circular plate 13 at the bottom of the semi-circular shell 4, horizontally extending fan-shaped plates 38 are respectively provided. The arc edges of both fan-shaped plates 38 are in close contact with the inner arc surface of the semi-circular arc plate 31.

[0032] To implement the dust suppression device for use in a straw feed crushing workshop as described in this invention, connect the dust collector 19, motor 27, and blower 30 to a switch and power supply, respectively. In use, place the device in the straw feed crushing workshop where dust suppression is required, position the horn 5 above the dry straw crushing device, and turn on the dust collector 19, motor 27, and blower 30. Under the negative pressure suction of the dust collector 19, dust containing dry straw particles is drawn into the vertical dust inlet chamber 10 along the horn cavity 15, then through the inclined dust inlet chamber 11 to the cylindrical cavity 12, and finally falls into the multiple horn-shaped expansion joints on the turntable 14 located within the plate hole 37 area. Within diameter 22, the inclined dust inlet chamber 11 facilitates the entry of dust containing dry straw particles into the cylinder chamber 12. Small dust particles pass through the screen 23 within the funnel-shaped expansion diameter 22 and reach the dust collection bag 18. When a certain amount of small dust particles is reached, the door A8 is opened to clean or replace the dust collection bag 18. The exhaust net 9 facilitates the negative pressure generated by the exhaust fan 19. Large dry straw particles are blocked and stuck within the funnel-shaped expansion diameter 22 by the screen 23. The reducer 26 causes the turntable 14 to rotate slowly. As the turntable 14 rotates, multiple funnel-shaped expansion diameters 22 within the plate hole 37 area are rotated... When the material is placed inside the lifting chamber 25, due to the close contact between the turntable 14 and the two semi-circular plates 13, some of the dust containing dry straw particles that drifts to the top of the turntable 14 is scraped into the funnel-shaped expansion diameter 22 by the semi-circular plates 13 located at the top of the turntable 14. Inside the lifting chamber 25, the blower 30 located below the turntable 14 blows out the large dry straw particles stuck in the funnel-shaped expansion diameter 22. The arrangement of the semi-circular plate 31 and the fan-shaped plate 38 is more conducive to concentrating the airflow of the blower 30. The airflow forms an internal circulation around the semi-circular plate 31 in the lifting chamber 25, which is divided by the semi-circular plate 31. The arrangement of the semi-conical hopper 7 is conducive to the airflow within the lifting chamber 25. With smooth internal circulation, the large dry straw particles blown out of the lifting chamber 25 will fall along the area outside the semi-circular plate 31. Since there is a filter screen 36 at the bottom of the semi-circular plate 31, the large dry straw particles cannot be adsorbed to the bottom of the filter screen 36 under their own weight, and instead fall into the bottom of the lifting chamber 25. Since the top of the semi-conical cavity 32 and the bottom of the lifting chamber 25 are connected, and the top of the storage chamber 33 and the bottom of the semi-conical cavity 32 are connected, the large dry straw particles eventually fall into the bottom of the storage chamber 33. When the large dry straw particles collected in the storage chamber 33 reach a certain amount, the door B29 is opened to take out and recycle the large dry straw particles.

[0033] The parts of this invention not described in detail are prior art.
