Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application.
[0030] Embodiment 1, please refer to Figures 1 to 4 The present application provides a technical solution: a coal mining water-coal separation device, which comprises a device body 1, a feed pipe 101 is fixedly embedded on the top of the device body 1, a partition plate 102 is fixedly embedded in the inside of the device body 1, a reciprocating screw rod 103 is movably embedded in the inside of the device body 1 and at the bottom of the partition plate 102, a sliding block 104 is threadedly connected to the outer surface of the reciprocating screw rod 103, a scraper 105 is fixedly installed at the bottom of the sliding block 104, a sliding rod 106 is slidingly connected to the inside of the scraper 105 on both sides, the two sliding rods 106 are fixedly embedded in the inside of the device body 1, a filter plate 107 is fixedly embedded in the inside of the device body 1, the bottom of the scraper 105 is movably connected to the top of the filter plate 107, a cover plate 108 is movably embedded in the inside of the device body 1 and at the top of the filter plate 107, a first rotating rod 109 is fixedly installed at the left side of the reciprocating screw rod 103, a first belt pulley 110 is fixedly sleeved on the outer surface of the first rotating rod 109, a motor 111 is arranged on the left side of the device body 1 close to the top, a support 112 is arranged on the outer surface of the motor 111, and the support 112 is fixedly installed on the left side of the device body 1.
[0031] In this embodiment, after the water is separated from the coal, it falls due to its own gravity, passing through the partition 102 and landing on the top of the filter plate 107. The filter plate 107 then performs a second filtration to separate the coal dust contained within the water. The filtered water then falls into the device body 1 through the filter plate 107. At this point, personnel can open the one-way valve 206 to allow the water to flow out of the device body 1 through the outlet pipe 205. The separated coal dust will remain on the top of the filter plate 107. Then, personnel can start the motor 111 through the power supply system of the motor 111 on the support member 112. When the motor 111 is running, it can drive the output shaft to the second pulley 113, and then the second pulley 113 drives the belt body 114. This allows the belt body 114 to move through the second pulley 113. A pulley 110 drives the first rotating rod 109, which in turn drives the reciprocating screw 103 to rotate. When the reciprocating screw 103 rotates, it drives the slider 104 and the scraper 105 to slide left and right through the sliding rod 106. The scraper 105 scrapes the coal powder on the filter plate 107 to prevent coal powder from accumulating on the filter plate 107 and causing blockage. After the device body 1 is used, the personnel can open the cover plate 108 to clean the coal powder on the filter plate 107. Through the structure of the filter plate 107 and the scraper 105, not only can the separated water be filtered a second time to ensure the cleanliness of the water and reduce the waste of coal powder, but the ability to scrape the coal powder on the filter plate 107 can also effectively prevent the coal powder from accumulating on the filter plate 107, avoid blockage, and reduce the frequency and labor intensity of manual cleaning.
