Embodiment Construction

[0038] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0039] figure 1 It is a structural schematic diagram of a filter device provided by an embodiment of the present invention, and the filter device can be used to filter liquid in a production well of a coal seam. The filter device may include: a first filter assembly 01, a power fluid tank ( figure 1 not shown) and connecting pipe assembly 02. The first filter assembly 01 may be located in a well (such as a coal seam production well), the power fluid tank may be located outside the well, and the first end of the connecting pipe assembly 02 may be configured to communicate with the rodless pump 10 . The connecting pipe assembly 02 can communicate with the first filter assembly 01 through the rodless pump 10 . The second end of the con...

Abstract

The invention discloses a filtering device and a drainage and mining system, and relates to the field of filtering equipment. The filtering device comprises a first filtering assembly (01), a power liquid tank and a connecting pipe assembly (02), wherein the first filtering assembly (01) is communicated with the power liquid tank through the connecting pipe assembly (02). Liquid in a well is firstly filtered by a first filtering unit (011a) and a second filtering unit (012a) in the first filtering assembly (01) and then is conveyed into the power liquid tank through a connecting pipe assembly (03). Due to the fact that the first filtering unit (011a) and the second filtering unit (012a) are not prone to being blocked, a rodless pump (10) can work continuously and stably, and the drainage and mining efficiency of the rodless pump (10) to a coal seam production well is effectively improved.

Description

technical field [0001] The present application relates to the field of filtering equipment, in particular to a filtering device and a drainage system. Background technique [0002] In the process of coal seam development, a rodless pump is required to drain coal seam production wells. When the rodless pump works, it needs to be driven by power fluid. The power fluid is usually located in the power fluid tank outside the coal seam production well. The rodless pump in the process of drainage can lift the liquid in the production well of the coal seam into the power fluid tank, so that there is always power fluid in the power fluid tank. [0003] In the related art, due to the high content of impurities (for example, particles) in the liquid in the production well of the coal seam, in order to prevent the liquid with high particles from affecting the normal operation of the rodless pump, a filter screen is usually set in the power fluid tank to prevent the lift. The fluid that...
