Coal mining screening device with dust splashing preventing function

Abstract

The invention discloses a coal mining screening device with a dust splashing preventing function, and relates to the technical field of coal mines. The coal mining screening device comprises a working box, a water filtering plate is slidably installed on the inner wall of the working box, the outer wall of the bottom of the water filtering plate is elastically connected with the inner wall of the working box through an elastic piece, a screening plate is fixedly embedded in the inner wall of the working box, and a rotating column is rotatably installed between the bottom of the water filtering plate and the top of the screening plate; and a grid baffle is fixedly embedded in the outer wall of the rotating column, and a water outlet pipe is fixedly installed between the water filtering plate and a water storage tank and communicates with the water filtering plate and the water storage tank. According to the coal mining screening device with the dust splashing preventing function, a buffering mechanism is arranged in the working box so that vibration of the water filtering plate can be effectively relieved, damage caused by too large impact force is prevented, and meanwhile filtering and separation of water can be promoted through vibration of the water filtering plate; and meanwhile, separation can be promoted through the grid baffle, screen holes in the screening plate can be scraped and cleaned, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of coal mines, in particular to a screening device for coal mine development with the function of preventing dust from splashing. Background technique [0002] Coal mines are areas where human beings exploit coal resources in coal-rich mining areas, and are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far away from the surface, it is generally selected to excavate the coal by digging the roadway underground, which is an underground coal mine. When the distance between the coal seam and the surface is very short, it is generally chosen to directly strip the surface soil layer to excavate coal, which is an open-pit coal mine. The vast majority of coal mines in my country are underground coal mines. Coal mines include large areas above and below ground and associated facilities.

Problems solved by technology

[0003] In the prior art, in the process of coal mine mining, due to the need to screen the coal mine and the dust generated by the fall of the coal mine, it is usually treated by spraying water to reduce dust and prevent splashing, but due to the gravity of the coal mine when it falls The impact of the impact will impact the water filter plate in the water spray and dust suppression, resulting in damage to the water filter plate, thus affecting the overall work efficiency of water spray and dust suppression
