Description

Technical Field

[0001] The utility model relates to the technical field of coal mine equipment, in particular to an electromechanical dust removal device for a coal mine. Background Art

[0002] The dust in coal mines is large and of high concentration, and the equipment located underground is prone to dust accumulation. In order to prevent the dust from having an adverse effect on the equipment, the equipment needs to be dusted. However, most of the existing dust removal equipment has low dust removal efficiency and needs to be improved.

[0003] A Chinese patent with authorization announcement number CN217400890U discloses a dust removal device for coal mine electromechanical use. When the device is removing dust, a water pump draws water out of the water tank and sprays it toward the dust from a sprinkler head through a water pipe, so that the dust is soaked and falls into the dust collection box to prevent the dust from being raised again, thereby achieving a better dust removal effect. Through the setting of a hair dryer, when the machine body generates heat when used for a long time, the hair dryer is started to dissipate the heat of the machine body to prevent the internal parts from being damaged by excessive temperature and affecting the use of the machine body.

[0004] However, the device still has some shortcomings: the device requires one machine and one pair, and only absorbs dust through airflow. It is not effective in cleaning dust attached to the surface of the equipment and is prone to dead corners. At the same time, the device only uses water mist for spraying dust removal. The dust in the air can still be easily blown into the outside of the device under the action of the fan, and the dust removal is not thorough. Utility Model Content

[0005] The utility model aims to provide a coal mine electromechanical dust removal device in view of the problems existing in the background technology.

The dust hood 8 is connected to the movable plate 4, and a roller brush assembly is arranged in the dust hood 8. The roller brush assembly includes a brush roller 9 arranged in the dust hood 8 and a motor C10 for driving the brush roller 9 to rotate. The reversing drive assembly drives the dust hood 8 to adjust the opening direction of the dust hood 8. The reversing drive assembly includes a motor A61 and a motor B7. A mounting frame 6 is provided at the bottom of the movable plate 4 and is rotatably connected thereto. A motor B7 is provided on the movable plate 4 and is driven to connect the mounting frame 6.

A plurality of electrostatic adsorption plates 16 are provided in parallel in the processing box 12. The electrostatic adsorption plates 16 include an anode plate and a cathode plate. The anode plate and the cathode plate are arranged at intervals, and an air flow channel is formed between two adjacent anode plates and cathode plates. The water outlet of the nozzle 18 is located inside each air flow channel and faces the cathode plates and the anode plates on both sides. The material receiving box 15 is located below the electrostatic adsorption plate 16. The fan 20 connects the processing box 12 with the outside world, and the electrostatic adsorption plate 16 is located between the input end of the fan 20 and the pipe mouth of the conduit 11. And a spray assembly, the water outlet of the spray assembly is located between each adjacent two electrostatic adsorption plates 16. The spray assembly includes a water pump 19 and a nozzle 18.
