[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] Refer to Figures 1-4 , a multifunctional environmental protection dust collection system, including a conveyor 9 for transporting coal. Above the conveyor 9, there is an intercepting hood 1 for preventing coal powder from flying. The surface of the intercepting hood 1 is connected to a dust collecting box 3 through a dust suction pipe 2. One end of the outlet of the dust suction pipe 2 is arranged inside the dust collecting box 3. The bottom of the dust collecting box 3 is two symmetrically arranged inclined planes. Inside the dust collecting box 3, there is a dispersion cone 4 fixedly connected for dispersing the airflow at the outlet of the dust suction pipe 2.

[0025] It can be understood that by setting the intercepting hood 1, the coal powder generated during the blanking process of the feed pipe 10 is blocked to prevent flying. By setting the dispersion cone 4, it is convenient to make the airflow ejected from the outlet of the dust suction pipe 2 diffuse around, improving the wetting effect on the coal powder.

[0026] Specifically, above the inside of the dust collecting box 3, there is a spraying assembly 5 for making the coal powder sink. The spraying assembly 5 includes a plurality of spraying pipes 501 and a connecting pipe 502 for connecting the plurality of spraying pipes 501. The plurality of spraying pipes 501 are all arranged inside the dust collecting box 3. One end of the connecting pipe 502 is provided with a sealing joint 503 for connecting to a water source.

[0027] It can be understood that the water source is connected to the connecting pipe 502 through the sealing joint 503 and is conveyed into the plurality of spraying pipes 501. Under the action of the plurality of spraying pipes 501, water mist is sprayed to wet the coal powder.

[0028] Specifically, at the bottom of the dust collecting box 3, there is a screw feeder 7 for discharging the coal powder. The screw feeder 7 includes a feeding pipe 701 connected to the dust collecting box 3 and a screw auger 702 for discharging the coal powder. The screw auger 702 is rotatably connected inside the feeding pipe 701 through a bearing. The outlet of the feeding pipe 701 is a contraction port. One end of the screw auger 702 is adapted to the contraction port. The screw auger 702 is driven by a driving motor.

[0029] It can be understood that the driven motor drives the screw auger 702 to extrude the wetted pulverized coal towards the outlet position of the feeding pipe 701. With the cooperation of the contraction port and the pressure valve 8, the pulverized coal is extruded into blocks for easy collection and use.

[0030] Specifically, a pressure valve 8 is arranged at the outlet position of the feeding pipe 701. A blanking pipe 10 is communicated with the surface of the intercepting cover 1, and a blower 6 is arranged in the middle of the dust suction pipe 2.

[0031] It can be understood that by setting the pressure valve 8, the outlet of the feeding pipe 701 can be closed, so that the screw auger 702 can form an extrusion effect on the pulverized coal. When the pressure is greater than the set value, the pressure valve 8 opens to discharge the extruded coal blocks.

[0032] Specifically, two sealing sleeves 11 are penetrated through the surface of the dust collection box 3. A sliding frame 12 is slidably connected to the surfaces of the two sealing sleeves 11. Two scraping plates 13 for cleaning the bottom inclined surface of the dust collection box 3 are fixedly connected to the lower surface of the sliding frame 12. A driving mechanism 14 for driving the sliding frame 12 to slide is arranged on the surface of the dust collection box 3. The driving mechanism 14 includes a rack and a slide rail for the rack to slide. The slide rail is fixedly connected to the surface of the dust collection box 3, and the rack is fixedly connected to the surface of the sliding frame 12. A driving motor is fixedly connected to the surface of the dust collection box 3, and a gear is fixedly connected to the lower end of the output shaft of the driving motor. The gear meshes with the rack.

[0033] It can be understood that by setting the scraping plates 13, the sliding frame 12 drives the scraping plates 13 to move on the inclined surface at the bottom of the dust collection box 3, so as to clean the pulverized coal adhered to the inclined surface. The driving motor drives the gear to rotate, and with the cooperation of the gear and the rack, the sliding frame 12 is driven to slide on the surfaces of the two sealing sleeves 11.

[0034] Specifically, a pressure relief valve 15 is arranged on the side surface of the dust collection box 3.

[0035] It can be understood that by setting the pressure relief valve 15, it is convenient to discharge the redundant air in the dust collection box 3 and balance the pressure inside and outside the dust collection box 3.

[0036] In this utility model, coal is conveyed to the surface of conveyor 9 through blanking pipe 10. Under the action of intercepting hood 1, the pulverized coal generated during the blanking process of blanking pipe 10 is blocked. Through fan 6, suction is generated in dust suction pipe 2, and the floating pulverized coal is extracted into dust collection box 3. Under the action of dispersion cone 4, the airflow and pulverized coal ejected from the outlet of dust suction pipe 2 diffuse around. Water mist is sprayed through multiple spray pipes to wet the pulverized coal so that it sinks to the surface of feeding pipe 701. The spiral auger 702 is driven to rotate by the driving motor, and the wetted pulverized coal is extruded towards the outlet position of feeding pipe 701. Under the cooperation of the contraction opening and pressure valve 8, the pulverized coal is extruded into blocks. When the extrusion pressure is greater than the set value, pressure valve 8 opens to discharge the extruded coal blocks. At the same time, the driving motor drives the gear to rotate. Under the cooperation of the gear and the rack, carriage 12 reciprocally slides on the surfaces of two sealing sleeves 11, driving scraper 13 to move on the inclined surface at the bottom of dust collection box 3 to clean the pulverized coal adhered to the inclined surface.

Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
