Description

Technical Field

[0001] The invention belongs to the technical field of rock dust filtering, and in particular relates to a rock dust filtering device for mining. Background Art

[0002] Rock dust refers to rock powder that can remain in a floating state for a long time and is used to prevent coal dust explosions. The content of combustible matter does not exceed 5%, the content of free silica does not exceed 10%, and it does not contain any harmful or toxic mixtures. During the production process of rock powder, there will be gravel that has not been ground into powder, which needs to be filtered using a filtering device before use.

[0003] Therefore, when filtering the existing rock powder, the processed rock powder is poured into the filter net, and then a device drives the filter net to shake and filter. In addition, the staff needs to manually collect the gravel on the surface of the filter net every once in a while, and the filter net needs to be cleaned every once in a while, which affects normal production and increases unnecessary labor intensity of the staff. Summary of the invention

[0004] The purpose of the present invention is to provide a rock powder filtering device for mining. Through the setting, the problem of the existing rock powder filtering device that when in use, the staff needs to manually collect the gravel on the surface of the filter screen and the filter screen needs to be cleaned at regular intervals is solved.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The present invention is a rock powder filtering device for mining, comprising a box body, the upper surface of the box body is fixedly connected to a protective shell, the inner side wall of the protective shell is rotatably connected to a filtering assembly, one side of the protective shell is fixedly connected to a feed pipe, the end of the feed pipe away from the protective shell is fixedly connected to a discharge box, the front of the box body is fixedly connected to a discharge port, one side of the box body is fixedly connected to a discharge port, the lower surface of the box body is fixedly connected to support legs, and the inner bottom wall of the box body is fixedly connected to a transmission assembly.

[0009] Furthermore, a driven gear is meshed on the surface of the outer gear ring, and the surface of the driven gear is meshed and connected with an inner gear ring away from the outer gear ring. The inner arc surface of the outer gear ring is fixedly connected to an inner roller. There are three driven gears, and the three driven gears are distributed in a circular array between the outer gear ring and the inner gear ring. A stirring blade is sleeved on the outer arc surface of the inner roller close to the inner gear ring.

[0010] Furthermore, the transmission assembly includes a motor, which is fixedly connected to the lower surface of the box through a support, and the output end of the motor is fixedly connected to a rotating rod, and the surface of the rotating rod is sleeved with a transmission pulley A, and the surface of the rotating rod near the transmission pulley A is sleeved with a transmission pulley B.
