Abstract

The invention relates to a pneumatic movable mining drilling flushing fluid recycling device which comprises a pneumatic walking device, a self-cleaning solid-liquid separator, a flat plate ceramic membrane purification device and a pneumatic control system, wherein the self-cleaning solid-liquid separator, the flat plate ceramic membrane purification device and the pneumatic control system are integrated on the pneumatic walking device. A water tank is arranged below the self-cleaning solid-liquid separator in a communicating mode, and the pneumatic control system is connected into an underground coal mine gas source. The recycling device can recycle coal cinder and recycle waste liquid. According to the device, underground compressed air is used as a power source to separate and recycle drilling wastewater of a directional drilling machine, so that the problem of discharge of wastewater and waste residues in a drilling site is solved, use of fresh water sources is reduced, an underground power source is not used, the underground construction environment is improved, and energy sources such as water and electricity are saved; and a foundation is laid for improving the economic cost on a mine and the construction environment of a drill site, good social benefits and economic benefits can be generated, and the device has popularization and application values.

Description

technical field [0001] The invention belongs to the field of coal mines, and relates to a pneumatic mobile mine drilling flushing fluid recycling device. Background technique [0002] During the drilling process, clear water is mainly used as the flushing medium, and the drill cuttings produced during the drilling construction are a mixture of drilling slag and water. [0003] Near-horizontal directional drilling in underground coal mines is to pressurize the water through the motor-driven mud pump and inject it into the motor at the bottom of the hole to drive the drill bit to cut and drill the coal rock. Therefore, a large amount of drilling fluid is required, and a large amount of drilling waste fluid is generated at the same time. The hole waste liquid contains a large amount of coal cinders or cuttings, which are currently discharged directly at the drilling site, causing water accumulation in the drilling site, blockage of drainage channels, and finally increased coal ...
