Description

Technical Field

[0001] The invention relates to the technical field of coal mining, in particular to a matching high-pressure spray box for coal mining equipment. Background Art

[0002] During the coal mining process, mining equipment is needed to crush the coal and remove it from the coal seam. During the crushing process, a large amount of coal dust is easily generated. When the air contains a large amount of coal dust, it will not only be inhaled into the workers' lungs through the human respiratory system, causing health damage, but may also cause dust explosions under certain circumstances, resulting in serious mining accidents. Therefore, it is necessary to control the coal dust content in the air during the mining process. The existing method of controlling coal dust is mainly to directly install a simple atomizing nozzle on the mining equipment to achieve dust reduction. However, due to the difficulty in effectively controlling the spraying direction of the atomizing nozzle and the low spray pressure, the dust reduction effect is not ideal, and it is difficult to effectively meet existing usage needs.

[0003] If a new type of dust suppression spray box is invented that is easy to control the spray direction and has better spray coverage, this problem can be effectively solved. To this end, we provide a matching high-pressure spray box for coal mining equipment. Summary of the Invention

A controller 6 and an energy storage device 26 are fixedly installed on the box body 1 by bolts.

[0024] Working Principle: This device is primarily used for installation on coal mining equipment to spray and suppress coal dust generated during the mining process. During use, the device's insertion mount 28 can be plugged into the corresponding portion of an external coal mining device, and then the external mining device and traction mount 27 can be secured with bolts. The external liquid supply pipe is then fixedly connected to the device's docking pipe 19. The external three-phase power supply is then properly connected to the corresponding electrical equipment on the device in accordance with the corresponding technical requirements. The energy storage device 26 is primarily used to convert the external three-phase power into direct current (DC) for supply to the controller 6. During operation, the water injection pump 20 first injects water from the external liquid supply pipe into the water tank 21. The water injection pump 20 is primarily used to prevent insufficient water pressure within the external liquid supply pipe from causing a lack of adequate water flow within the water tank 21. When the external water supply pressure is sufficient, the water injection pump 20 can be omitted. The water in the water tank 21 will be sent to the side atomizing nozzle 25 through the second liquid supply pump 21. The side atomizing nozzle 25 can spray the dust at the front end and side of the box body 1 after atomizing the water. At the same time, it can also be effectively used to humidify the dust on the ground to prevent the dust on the ground from floating into the air again. At the same time, the first liquid supply pump 22 can send the water in the water tank 21 into the top atomizing nozzle 11. The top atomizing nozzle 11 is mainly used to spray water to reduce dust in the space above the box body 1, and the top atomizing nozzle 11 sprays water. During the process, the alkaline direction of the rotating motor 9 can be adjusted to effectively spray different areas, and the installation height of the top atomizing nozzle 11 can also be adjusted by the first fixing bolt 14, so that it can be better applied to mines with different mining heights. In addition, the device directly uses the high-pressure first liquid supply pump 22 and the second liquid supply pump 23 to supply liquid to the top atomizing nozzle 11 and the side atomizing nozzle 25 respectively, which can also enable the corresponding nozzles to spray the atomized water mist farther, thereby obtaining a larger coverage area and dust reduction effect. The device can also be removed from the coal mining equipment and then installed on the chassis 5 for separate use. At this time, the user can push the armrest seat 8 by hand to drive the displacement of the device, so that it can be transported to different areas for spray dust removal work, which is more convenient to use and has high practical value.
