[0002] Coal mine wastewater contains a large amount of suspended matter, coal slime and mud sand. Coal mine and waste gas underground coal mine wastewater is both a source of pollution and a valuable water resource. In order to prevent coal mine wastewater from polluting the environment, it is necessary to use coal mine underground wastewater filter devices to filter and purify the wastewater.

[0003] After searching, the existing patent (Announcement No.: CN220159349U) discloses a coal mine underground wastewater filter device. During use, the device is provided with a guide plate, a first filter screen, a second filter screen, a drain pipe, a valve and a baffle. Wastewater enters the interior of the box through the water inlet. The first filter screen and the second filter screen inside the box can perform secondary filtration on the wastewater, so that impurities in the wastewater can be filtered to the top of the first filter screen and the second filter screen. The baffles at both ends of the top of the first filter screen and the second filter screen can limit the impurities, and the guide plate can filter the wastewater. The guide facilitates the discharge of wastewater through the valve, and filtering the wastewater can prevent the discharge of wastewater from polluting the environment. On the other hand, by providing a first connecting plate, a connecting rod, a hydraulic cylinder, a mounting frame, a first slider, a slide groove, and a second slider, when there are more impurities on the top of the first filter screen and the second filter screen, the hydraulic cylinder is started. Since the hydraulic cylinder is movably hinged between the second slider and the mounting frame and the second slider and the first slider slide inside the slide groove, starting the hydraulic cylinder can make the other side of the first filter screen and the second filter screen rise, so that the first filter screen and the second filter screen can be tilted and discharged. However, the inventor found that the prior art has the following problems in the process of realizing the utility model: during the use of the above-mentioned wastewater filter device, when it is necessary to discharge the impurities on the surface of the filter screen, the first filter screen and the second filter screen need to be tilted. Under this operation, the inner cavity of the overall filter is connected to the external environment, so it is necessary to stop the wastewater filtering operation in advance before the impurity discharge operation can be performed. Under such a premise, it will cause delays in the progress of wastewater treatment and reduce the efficiency of wastewater treatment.
