Slag and water discharging filtering device for mining

Abstract

The utility model relates to a slag and water discharging filtering device for mining. The device comprises an underframe, a first filtering barrel and a second filtering barrel, wherein one ends of the first filtering barrel and the second filtering barrel are communicated and connected with a water outlet pipe, the other ends of the first filtering barrel and the second filtering barrel are respectively communicated with a first reversing valve and a second reversing valve, the first reversing valve and the second reversing valve are communicated and connected with an external water source, the first reversing valve and the second reversing valve are respectively provided with a first blow-off pipe and a second blow-off pipe, the first reversing valve is provided with a first pneumatic actuator for controlling the first filtering barrel to be communicated with any one of a water inlet pipe and the first blow-off pipe, a second pneumatic actuator for controlling the second filtering barrel to be communicated with any one of the water inlet pipe and the second blow-off pipe is mounted on the second reversing valve, a control box is arranged on the bottom frame, and a first main machine pneumatically connected with the first pneumatic actuator and a second main machine pneumatically connected with the second pneumatic actuator are arranged in the control box. According to the invention, the filtering effect is improved, the cost is saved, the service life is prolonged, the explosion-proof grade is high, and the device can be safely used under all mines.

Description

technical field [0001] The invention belongs to the technical field of mine drainage equipment, and in particular relates to a mine slag discharge water filter device. Background technique [0002] Coal mines are the main natural resources of our country. Rational use and mining of coal mines is an important part of promoting the economic development of our country. During the coal mine mining process, a large amount of water often seeps out of the cracks in the rock formations, which will hinder the mining work. Therefore, it is necessary to pump water at all times. However, stone chips and some impurities are often pumped into the water pipe during the pumping process. The length of the mine tunnel is generally long and has a slope, and the water pipe is often blocked. At present, the easiest way to filter water is to install a filter barrel on the water pipe, but this requires workers to clean the filter barrel and replace the filter element regularly, which is very time-...
