[0002] During the mining process, various ores are produced. Before use, the ores need to be crushed in a crusher. During the crushing process, a large amount of dust is generated, which not only causes the loss of ore raw materials but also affects the health of workers. Therefore, dust suppression devices are needed to reduce dust. Most existing dust suppression devices spray water mist in the working environment to settle the scattered dust. This inevitably causes some dust to escape into the working environment. The water mist method can easily make the working environment humid and even cause water accumulation. Summary of the Invention

[0003] In order to solve the problem that most existing dust removal devices use water mist to remove dust in the working environment to settle the scattered dust, which inevitably causes some dust to escape into the working environment, and the water mist method easily makes the working environment humid and even water accumulation occurs, the utility model proposes a dust reduction device for an ore crusher, which transports the dust in the crusher to a dust removal box through a first suction fan and a second suction fan, and then settles and adsorbs the dust through a spray mechanism and a first filter, so that the scattered dust is settled and no water accumulation occurs outside.

[0004] The dust collecting box is connected with the dust collecting pipe at the bottom of the dust collecting box, and the dust collecting pipe is connected with the dust collecting box at the bottom of the dust collecting box. One end of the dust suction pipe is connected to the crusher and is located at the upper part of the crusher. The output shaft end of the first suction fan passes through the side wall of the box and enters the box. The end is connected with a fan blade, and the fan blade is in the box. The first filter divides the dust removal box into a dust removal chamber and a collection chamber, and separates the outlet of the dust conveying pipe from the suction end of the second suction fan, so that the dust can be directly adsorbed by the first filter.

[0005] Furthermore, the bottom plate of the dust removal chamber is tilted, with the end of the tilted bottom plate in the dust removal chamber away from the first filter being the highest point. The tilted bottom plate makes it easier to collect the water mist sprayed by the spray mechanism.

[0006] Furthermore, the water outlet pipe includes a main pipe and multiple branch pipes connected to the main pipe, one end of the main pipe is connected to the water pump, and the ends of the multiple branch pipes extend into the dust removal chamber and are connected to the nozzle.

[0007] Furthermore, the dust removal chamber is provided with a cleaning mechanism comprising a brush, a motor, a screw, and a polished rod. The screw and polished rod are located on either side of the dust removal chamber. Connecting blocks are provided at both ends of the brush. The connecting block at one end of the brush is threadedly connected to the screw, and the connecting block at the other end is slidably connected to the polished rod. The bristles of the brush are in close contact with the surface of the first filter, and as the brush moves up and down, it helps to clean the surface of the first filter.

In the present invention, the suction end of the first suction fan is facing the dust suction pipe to absorb the dust generated in the crusher into the box body, and then the dust collection box is formed into a negative pressure environment through the second suction fan arranged in the dust collection box. At this time, the dust in the box body enters the dust collection box through the dust conveying pipe, and the spray mechanism arranged on the dust collection box sprays water mist to settle the dust when the dust enters the dust collection box. The part of the dust that has not been settled is then absorbed by the first filter net under the action of the second suction fan, thereby realizing the treatment of dust, and the water mist treatment in the dust collection box avoids water accumulation.

[0015] 2. The utility model is provided with a cleaning mechanism in the dust removal chamber. When the first filter is clogged due to the combination of dust and water mist, the motor drives the second bevel gear to rotate, and the first bevel gear connected to the second bevel gear drives the screw to rotate.
