Self-ventilating coal-mine dust removing device

Abstract

The invention discloses a self-ventilating coal-mine dust removing device. The device comprises a device shell, a dust removing cavity is divided in the device shell, an exhaust fan is arranged at anair inlet in the side wall of one side of the dust removing cavity, a plurality of air outlet holes are formed in the side wall of the other side of the dust removing cavity, a filtering plate is arranged in the middle in the dust removing cavity, the bottom of the side, close to the exhaust fan, in the dust removing cavity is provided with a collecting groove, the portion, outside the air outletholes, of the device shell is provided with a dust discharging cavity, and a partition plate is arranged in the middle in the dust discharging cavity. According to the self-ventilating coal-mine dustremoving device, a driving motor works to drive a cranked rod assembly to rotate, the cranked rod assembly drives a sliding rod to reciprocate in the device shell, a cleaning brush on a fixing base atone end of the sliding rod is adopted for cleaning to make dust fall into the collecting groove and discharged into a collecting box connected with the exterior along an inner slideway, the situationthat the dust removing and filtering effect is reduced due to the accumulation of a lot of dust on the surface when the filtering plate works for a long time is avoided, and the device is convenientto use during cleaning.

Description

technical field [0001] The invention belongs to the technical field of coal mine dust removal devices, and in particular relates to a self-ventilating coal mine dust removal device. 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. A coal mine is a reasonable space excavated by humans when excavating geological layers rich in coa...

Problems solved by technology

[0003] The prior art has the following problems: the current self-ventilated coal mine dust removal device still has residual dust in the discharged air during use, which can still cause environmental pollution. When used, the interior of the self-ventilated coal mine dust removal device is often cleaned by replacing the filter plate, causing cleaning Inconvenient, no self-cleaning
