[0025] This application provides a cooling and dust removal device for a continuous mining machine.

[0026] like Figure 1 As shown, a cooling and dust removal device for a continuous mining machine includes a main water inlet pipe 1, a first branch pipe 2, a second branch pipe 3, and a cooling water outlet pipe 4. The main water inlet pipe 1 is connected to a water source. One end of the first branch pipe 2 is connected to the main water inlet pipe 1, and the other end of the first branch pipe 2 is connected to an external spray nozzle 21. One end of the second branch pipe 3 is connected to the main water inlet pipe, and the other end of the second branch pipe 3 is connected to a cooling channel within a functional module of the continuous mining machine. The first end of the cooling water outlet pipe 4 is connected to a cooling channel within a functional module of the continuous mining machine, and the second end of the cooling water outlet pipe 4 is connected to a shovel spray nozzle 31 and a conveyor spray nozzle 32.

[0027] Because the outlet diameter of the external spray nozzle 21 is small, impurities in the cooling water can easily clog it. This application sets up independent cooling water and external spray water supply for the continuous mining machine, thereby improving the clogging problem of the external spray nozzle 21 and enhancing the spraying effect. At the same time, because the outlet diameters of the shovel spray nozzle 31 and the conveyor spray nozzle 32 are large, they are not affected by impurities in the cooling water and are unlikely to clog, reducing the frequency of replacing the spray nozzles. Therefore, cooling water is supplied to the shovel spray nozzle 31 and the conveyor spray nozzle 32, and the cooling water is used for secondary spraying to reduce dust, reducing water waste while ensuring the entire spraying range and spraying effect of the continuous mining machine.

[0028] The main water inlet pipe 1 is equipped with a water filter 11, which filters the main water inlet, reduces impurities entering the external spray nozzle 21, further improves the clogging problem of the external spray nozzle 21, and improves the spraying effect.

[0029] The first branch pipe 2 is equipped with a first manual shut-off valve 22, which is used to control the start and stop of the external spray.

[0030] The second branch pipe 3 is equipped with a second manual shut-off valve 33, which is used to control the flow of cooling water to various components of the continuous mining machine.

[0031] The second branch pipe 3 is connected to the first cooling water inlet pipe 34 and the second cold water inlet pipe.

[0032] The traction control box 5, left travel motor 51, left loading motor 52, left cutting motor 53, right travel motor 54, hydraulic oil pump motor 55, right loading motor 56, and right cutting motor 57 of the continuous mining machine are all equipped with cooling channels. The cooling channels of the traction control box 5, left travel motor 51, left loading motor 52, and left cutting motor 53 are connected in series in sequence, and the cooling channels of the right travel motor 54, hydraulic oil pump motor 55, right loading motor 56, and right cutting motor 57 are connected in series in sequence.

[0033] The other end of the first cooling water inlet pipe 34 is connected to the cooling channel of the traction control box 5, and the other end of the second cooling water inlet pipe 35 is connected to the cooling channel of the right travel motor 54. The outlet of the cooling channel of the left cutting motor 53 is connected to the first outlet pipe 36, and the outlet of the cooling channel of the right cutting motor 57 is connected to the second outlet pipe 37. The first outlet pipe 36 and the second outlet pipe 37 are connected to the cooling water outlet pipe 4.

[0034] The cooling water outlet pipe 4 is equipped with a water pressure and flow valve 41, which is used to maintain the water pressure entering the connecting shovel spray nozzle 31 and the transport machine spray nozzle 32.

[0035] In one embodiment, a cooling water outlet is provided between the water pressure flow valve 41 and the first end of the cooling water outlet pipe 4. In another embodiment, the cooling water outlet may also be provided on the first outlet pipe 36 and the second outlet pipe 37.

[0036] The continuous miner cooling and dust removal device also includes a third branch pipe 6. One end of the third branch pipe 6 is connected to the main water inlet pipe 1, and the third branch pipe 6 is connected to the air duct spray nozzle 61 inside the dust collection air duct of the continuous miner. The air duct of the continuous miner is the air inlet pipe of the dust collection system, which draws in and collects the dust floating around the continuous miner. The air duct spray nozzle 61 is used to spray water mist into the air duct. The water supply for the air duct spray is set independently from the cooling water supply, which improves the clogging problem of the air duct spray nozzle 61 and enhances the spraying effect.

[0037] The third branch pipe 6 is equipped with a solenoid valve 62 and a pressure regulator 63. The solenoid valve 62 is electrically connected to the pilot valve 64 of the dust collector in the dust collection duct of the continuous mining machine. When the dust collector starts, the solenoid valve 62 under the pilot valve sends a signal, the solenoid valve 62 opens, and the spray nozzles 61 in the duct begin to spray water. The pressure regulator 63 is used to control the water pressure entering the spray nozzles 61 in the duct. The pressure regulator 63 can dynamically adjust the spray water pressure according to the dust concentration to achieve efficient dust suppression.

[0038] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
