Scaling prevention and removal device for mine gas drainage equipment

Abstract

The invention relates to a scaling prevention and removal device for mine gas drainage equipment in the technical field of the mine gas drainage equipment. The device includes a processing box. The processing box, an air inlet pipe and an air outlet pipe are provided with flanges; the flanges are equipped with first bolts; mounting holes are installed on the processing box; cover caps are disposedon the processing box; the processing box is provided with inclined plates; a first filter plate, a second filter plate and a waterproof and breathable membrane are disposed between the inclined plates; the processing box is equipped with a cleaning structure; the processing box is provided with hoppers on the first filter plate, the second filter plate and the waterproof and breathable membrane;the hoppers are equipped with material unloading sleeve pipes, the material unloading sleeve pipes are provided with horizontal holes, and the material unloading sleeve pipes are provided with baffleplates; fixation structures are disposed on the baffle plates; the material unloading sleeve pipe on the right end is provided with a flow guiding pipe, and the flow guiding pipe is connected with asedimentation tank; the sedimentation tank is provided with an overflow pipe; the sedimentation tank is provided with a cover plate; a mounting frame and a drug adding pipe are disposed on the cover plate; a drive motor is installed in the mounting frame; the drive motor is provided with a rotation shaft; and the rotation shaft is provided with cross bars, and L-shaped scrapping plates are disposed on the cross bars. A drainage system of the device can operate normally, internal space of the equipment is guaranteed, discharge resistance is reduced, internal friction is reduced, and the efficiency of drainage equipment is improved.

Description

technical field [0001] The invention relates to the technical field of mining gas extraction equipment, in particular to a scale prevention and removal device for mining gas extraction equipment. 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 laye...

Problems solved by technology

[0003] The gas drainage equipment is the most important equipment in the entire drainage system. During the use of the drainage equipment, in areas with relatively hard water, scale formation occurs and the equipment is locked, making the drainage system unable to operate, and the scale generation shrinks the inside of the equipment. space, increase the discharge resistance, and increase the internal friction to cause the temperature of the equipment to rise sharply, which greatly reduces the efficiency of the extraction equipment. Once scaling is formed in the extraction equipment and cannot be removed, it will bring immeasurable damage to our safe production. loss of property and persons
