Description

Technical Field

[0001] This utility model belongs to the field of coal mine roadway dust removal, specifically relating to a washing and dust suppression device for a mining milling machine. Background Technology

[0002] Due to the dust and various operational requirements in mines, mining milling machines generally need to be equipped with a dust suppression and flushing system. This system enables low-pressure water spraying and high-pressure washing within coal mine roadways. Traditional milling machine dust suppression systems require at least two pumps to meet these different pressure requirements and usage scenarios. During operation, water is typically used for dust suppression, requiring low pressure and low flow. At the end of each workday, the machine needs cleaning, requiring high pressure and high flow. Current milling machine designs typically include dedicated water spraying pumps and high-pressure flushing pumps. However, this design, with pumps of different pressures, makes the milling machine cumbersome, costly, and difficult to maintain. Utility Model Content

[0003] The purpose of this utility model is to provide a dust suppression and flushing device for mining milling machines, which aims to use a combination of a water pump and a water pump valve group to adjust different pressures to meet different usage scenarios.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A dust suppression and flushing device for a mining milling machine includes a water supply tank, a water pump valve group, a high-pressure water pump, a low-pressure nozzle, and a high-pressure spray gun. The water supply tank and the high-pressure water pump are connected by a pipeline. An oil inlet pipeline and an oil outlet pipeline are provided between the water pump valve group and the high-pressure water pump. The low-pressure nozzle and the high-pressure spray gun are connected to the outlet of the high-pressure water pump through a tee.

[0005] Furthermore, the high-pressure water pump is equipped with a pressure gauge and a pressure regulating valve.

[0006] The beneficial technical effects of this utility model are as follows: This utility model utilizes a combination of a water pump valve group and a high-pressure water pump. By controlling the circulating hydraulic system, the water supply pressure of the high-pressure water pump is controlled. Then, low-pressure nozzles and high-pressure spray guns are used to handle water output under different pressure requirements. This eliminates the cumbersome design that originally required two water pumps and corresponding valve groups, greatly reducing procurement, usage, and maintenance costs and improving production efficiency.

[0011] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model, so that those skilled in the art can reproduce this technical solution after understanding the principle of this solution.

[0012] This embodiment discloses a washing and dust suppression device for a mining milling machine, which is installed on the main body of the milling machine and moves with the milling machine to complete low-pressure water spraying and high-pressure washing operations in the underground roadway.

[0013] like Figure 1 As shown, a dust suppression and flushing device for a mining milling machine includes a water supply tank 1, a water pump valve group 2, a high-pressure water pump 3, a low-pressure nozzle 4, and a high-pressure spray gun 5. The water supply tank 1 and the high-pressure water pump 3 are connected by a pipeline. An oil inlet pipeline 6 and an oil outlet pipeline 7 are provided between the water pump valve group 2 and the high-pressure water pump 3. The low-pressure nozzle 4 and the high-pressure spray gun 5 are connected to the outlet of the high-pressure water pump 3 through a tee.

[0014] like Figure 2 As shown, the high-pressure water pump 3 is equipped with a pressure gauge 8 and a pressure regulating valve 9.

[0015] In use, the water pump valve assembly has electrical control functions. After power is supplied, the hydraulic oil circulates through the oil inlet pipe 6 and the oil outlet pipe 7 in the high-pressure water pump 3, bringing pressure to the water pump to start working. At the same time, the water tank 1 provides water for the water pump to work. By adjusting the pressure regulating valves on the water pump valve assembly 2 and the high-pressure water pump 3, the pressure gauge reading meets the usage requirements of the specific scenario. Then, the low-pressure nozzle 4 or the high-pressure spray gun 5 is opened to achieve specific low-pressure water spraying or high-pressure flushing operations.
