Abstract

The application discloses a filtering device and a drainage system, which relate to the field of filtering equipment. The filter device comprises: a first filter assembly (01), a power fluid tank and a connecting pipe assembly (02), and the first filter assembly (01) and the power fluid tank communicate through the connection pipe assembly (02). The liquid in the well is first filtered through the first filter unit (011a) and the second filter unit (012a) in the first filter assembly (01), and then delivered to the power fluid tank through the connecting pipe assembly (03). Since the first filter unit (011a) and the second filter unit (012a) are not easy to be blocked, the rodless pump (10) can continue to work stably, effectively improving the performance of the rodless pump (10) on coal seam production wells. Drainage efficiency.

Description

Filtration device and drainage system technical field [0001] The application relates to the field of filtering equipment, in particular to a filtering device and a drainage system. Background technique In the coal seam development process, need to adopt rodless pump to carry out drainage work to coal seam production well, when this rodless pump works Power fluid is required, usually located in a motive fluid tank outside the coal seam production well. in the process of mining The rodless pump in the coal seam can lift the liquid in the coal seam production well to the power fluid tank, so that there is always movement in the power fluid tank. Liquor. In the related art, due to the high content of impurities (for example, particulate matter) in the liquid in the coal seam production well, In order to prevent the liquid with high particulate matter from affecting the normal operation of the rodless pump, a filter screen is usually installed in the power fluid tank t...
