[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0022] like Figure 1-Figure 2 As shown, the embodiment of the present invention provides a crushing device for raw materials of sintered coal gangue thermal insulation bricks, comprising a crushing box shell 1, and a feed hopper 6 is provided on the upper side of the crushing box shell 1, a discharge port 2 is provided on the side of the crushing box shell 1, and a pair of electric crushing rollers 7 are installed inside the crushing box shell 1. The staff can put the raw materials of sintered coal gangue thermal insulation bricks to be crushed into the crushing box shell 1 through the feed hopper 6, and the raw materials of sintered coal gangue thermal insulation bricks will be crushed by the two high-speed rotating electric crushing rollers 7. The crushed materials will fall to the inner bottom of the crushing box shell 1, and the staff can take out the crushed materials from the crushing box shell 1 through the discharge port 2;

[0023] A dust reduction chamber 17 is connected to the side of the crushing box housing 1, and an induced draft fan 14 is installed on the surface of the dust reduction chamber 17. An exhaust pipe 15 is connected to the outside of the induced draft fan 14. Three ventilation pipes 13 are connected to the outside of the dust reduction chamber 17, and the two ends of the three ventilation pipes 13 away from the dust reduction chamber 17 are respectively connected to connecting pipes 19;

[0024] An appropriate amount of dust suppression liquid 10 is stored inside the dust suppression chamber 17. An injection pipe 16 is provided at the top of the side of the dust suppression chamber 17, and a drainage pipe 18 is provided at the bottom of the side of the dust suppression chamber 17. A control valve is installed on the outside of the drainage pipe 18. The staff injects the dust suppression liquid 10 into the dust suppression chamber 17 through the injection pipe 16, and can discharge the wastewater inside the dust suppression chamber 17 through the drainage pipe 18 and the control valve.

[0025] A submersible pump 11 is installed inside the dust suppression chamber 17, and one end of the submersible pump 11 is connected to a liquid infusion tube 9, and a plurality of atomizing nozzles 8 are installed on the outside of the liquid infusion tube 9;

[0026] Two dust extraction cylinders 21 are connected to the inner bottom of the crushing box shell 1, and a filter mesh plate 22 is movably installed inside the dust extraction cylinder 21. The end of the exhaust pipe 15 away from the induced draft fan 14 is arranged inside the dust reduction chamber 17, and the two ends of the connecting pipe 19 are respectively connected to the three ventilation pipes 13 and the interior of the dust extraction cylinder 21.

[0027] In one embodiment of the present invention, when the electric crushing roller 7 crushes the raw material of coal gangue sintered insulation brick, a large amount of dust will be generated. This dust will float out through the feed hopper 6 and the discharge port 2, which will greatly affect the processing environment.

[0028] In response to the above technical problems, when the electric crushing roller 7 crushes the raw materials for sintered coal gangue thermal insulation bricks, the staff can turn on the induced draft fan 14, and the induced draft fan 14 sucks the dust-containing air inside the crushing box shell 1 through the exhaust pipe 15, the dust reduction chamber 17, the three-air duct 13, the connecting pipe 19 and the dust extraction cylinder 21, and allows the dust-containing air to enter the interior of the dust reduction chamber 17. At the same time, the staff turns on the submersible pump 11, and the submersible pump 11 pumps the dust reduction liquid 10 stored in the dust reduction chamber 17 into the interior of the infusion pipe 9, so that the dust reduction liquid 10 is sprayed out through a plurality of atomizing nozzles 8, and these atomized coal gangue thermal insulation brick raw materials will capture the dust in the air to purify the dust-containing air;

[0029] Moreover, before the dust-laden air enters the connecting pipe 19, it is filtered by the filter mesh plate 22 provided inside the dust extraction cylinder 21, thereby intercepting some of the crushed particles of the raw material for sintered coal gangue insulation bricks, thereby preventing the crushed particles of the raw material for sintered coal gangue insulation bricks from entering the interior of the dust reduction chamber 17;

[0030] Through the above technical scheme, in the process of the electric crushing roller 7 crushing the raw materials for sintered coal gangue thermal insulation bricks, the dust-containing air diffused in the interior of the crushing box shell 1 can be fully drawn out first, and then the mist dust reduction liquid 10 is used to fully capture and purify the dust in the air, thereby avoiding a large amount of dust from diffusing out of the crushing box shell 1 and polluting the processing environment, thereby improving the practicality of the crushing device for sintered coal gangue thermal insulation brick raw materials.

[0031] like Figure 1 and Figure 2As shown, in one embodiment of the present utility model, a slider 23 is installed on the side of the filter mesh plate 22, a slide rail 24 is provided inside the dust extraction cylinder 21, and the filter mesh plate 22 is slidably connected to the inside of the dust extraction cylinder 21 through the cooperation of the slider 23 and the slide rail 24, springs 20 are installed on both sides of the inside of the crushing box shell 1, and one end of the spring 20 is connected to the outside of the filter mesh plate 22, and a drive motor 3 and a rolling bearing 12 are respectively installed on both sides of the crushing box shell 1, and the output end of the drive motor 3 is connected to a rotating thin rod 5, and knocking cams 4 are installed on both sides of the outer side of the rotating thin rod 5, and the knocking cams 4 are arranged directly below the filter mesh plate 22.

[0032] In this embodiment, when the filter mesh plate 22 filters the dust-laden air for a long time, the mesh holes of the filter mesh plate 22 will inevitably be clogged by larger dust particles or crushed particles of the raw material of the coal gangue sintered insulation brick, which results in a decrease in the circulation efficiency of the dust-laden air in the entire purification structure.

[0033] In response to the above technical problems, the staff can turn on the drive motor 3 after a period of time. The output end of the drive motor 3 drives the rotating thin rod 5 to rotate through the rolling bearing 12, so that the two knocking cams 4 sleeved on the outside of the rotating thin rod 5 can continuously knock on the two filter mesh plates 22, so that the filter mesh plates 22 vibrate through the spring 20, the slide rail 24 and the slider 23, and then shake out and clean the debris attached to the surface of the filter mesh plate 22 and blocked in the mesh of the filter mesh plate 22, thereby improving the purification efficiency of the dust-containing air by the crushing device for the raw materials of coal gangue sintered insulation bricks.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
