Abstract
The invention provides a high precision pressure backwashing filter station for a coal mine. The filter station is composed of a pedestal, a backwashing control valve, a filter and a hand-operated directional valve. The backwashing control valve is installed on the pedestal; the filter and the hand-operated directional valve are installed on the backwashing control valve. A filter core assembly is arranged in the filter. A working medium reaches the filter core assembly through connection with a channel inside the body of the backwashing control valve, thereby realizing filtration. A feed liquid pressure gauge and a discharge liquid pressure gauge are arranged on the backwashing control valve; when pressure difference between the feed liquid pressure gauge and the discharge liquid pressure gauge is higher than a preset threshold value, a pollution spray device installed on the backwashing control valve automatically sprays to sound an alarm. The high precision pressure backwashing filter station provided by the invention has the advantages of a simple structure, a large filter area of a filter core, strong pollutant carrying capacity and a backwashing effect.
