The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0019] The first embodiment of this application is:

[0020] See also Figures 1 to 4,in, Figure 1 This is a schematic diagram of the overall structure of the coal washing wastewater treatment device of the first embodiment of the utility model.

The filter component includes a filter plate 109, a fixing seat 110, a limit bar 111 and a discharge rack 112. The guide component includes a sealing seat 113 and a guide seat 114. The above-mentioned scheme solves the problem that when the coal washing wastewater treatment device is in use, the filter screen separates water and impurities, but the filtered water and the crushed impurities are discharged from the bottom of the treatment barrel together, resulting in poor filtering effect. It can be understood that the above-mentioned scheme can be used in the scenario of discharging filtered water and impurities separately, and can also be used to solve the problem of cleaning the inner wall of the treatment box.

[0021] According to this specific embodiment, the number of the scraper 102 is multiple, and the multiple scrapers 102 are respectively slidably connected to the processing box 101 and are respectively located inside the processing box 101. The number of the discharge plates 103 is multiple, and the multiple discharge plates 103 are respectively fixedly connected to the scraper 102 and are respectively located on the inner side of the scraper 102. The number of the support plates 104 is multiple, and the multiple support plates 104 are respectively fixedly connected to the scraper 102 and are respectively located on the top of the scraper 102. The number of the rotating seats 105 is two, and the two rotating seats 105 are respectively fixedly connected to the discharge plate 103 and the support plate 104, and are respectively located in the middle of the processing box 101. The filter assembly and the guide assembly are respectively connected to the processing box 101. 101 is used to treat coal washing wastewater, and the scraper 102 is used to clean the inner wall of the processing box 101. The discharge plate 103 is arc-shaped and fits the surface of the filter plate 109. The support plate 104 provides support for the scraper 102, and the rotating seat 105 provides support and transmission for the support plate 104 and the discharge plate 103. When the device is in use, the rotation of the motor 107 drives the rotating seat 105 to rotate, and at the same time drives the support plate 104, the discharge plate 103 and the scraper 102 to rotate, and the impurities filtered by the filter plate 109 are scraped by the arc-shaped discharge plate 103, so that the impurities flow out from the discharge rack 112. At the same time, the rotation of the scraper 102 prevents impurities from sticking to the inner wall surface of the processing box 101.

[0022] Among them, the cover plate 106 is detachably connected to the processing box 101 and is located on the top of the processing box 101. The motor 107 is fixedly connected to the cover plate 106 and is located on the top of the cover plate 106. The transmission shaft 108 is connected to the motor 107 and passes through the cover plate 106 and the rotating seat 105. The cover plate 106 provides sealing for the processing box 101, the motor 107 provides power for the device, and the transmission shaft 108 provides transmission for the scraper assembly.

[0023] Secondly, the filter plate 109 is detachably connected to the treatment box 101 and is located inside the treatment box 101. The fixing seat 110 is rotatably connected to the transmission shaft 108 and is located between the transmission shaft 108 and the filter plate 109. The limiting strip 111 is fixedly connected to the filter plate 109 and is located between the filter plate 109 and the treatment box 101. The filter plate 109 is used to filter sewage, and the fixing seat 110 and the limiting strip 111 are used to fix the filter plate 109.

[0024] Again, there are two discharge racks 112, and the two discharge racks 112 are respectively fixedly connected to the processing box 101 and are respectively located on the outside of the processing box 101. The filtered impurities are driven by the discharge plate 103 and flow out of the processing box 101 from the surface of the discharge rack 112, so as to facilitate the separate discharge of the filtered water and impurities.

[0025] Finally, the sealing seat 113 is fixedly connected to the processing box 101 and is located at the bottom of the processing box 101. The guide seat 114 is fixedly connected to the sealing seat 113 and is located at the top of the sealing seat 113. The sealing seat 113 provides support for the guide seat 114 and provides sealing for the processing box 101. During filtration, the filtered water passes through the guide seat 114 and flows out of the processing box 101 from the gap between the guide seat 114 and the sealing seat 113, making it convenient to discharge the filtered water and impurities separately.

[0026] Using the coal washing wastewater treatment device of this embodiment, the treatment box 101 is used to treat the coal washing wastewater, the scraper 102 is used to clean the inner wall of the treatment box 101, the discharge plate 103 is arc-shaped and fits the surface of the filter plate 109, the support plate 104 provides support for the scraper 102, and the rotating seat 105 provides support and transmission for the support plate 104 and the discharge plate 103. When the device is in use, the rotation of the motor 107 drives the rotating seat 105 to rotate. At the same time, the support plate 104, the discharge plate 103 and the scraper 102 are driven to rotate, and the impurities filtered by the filter plate 109 are scraped by the arc-shaped discharge plate 103, so that the impurities flow out from the discharge rack 112. At the same time, the rotation of the scraper 102 prevents impurities from adhering to the inner wall surface of the treatment box 101, which solves the problem that when the coal washing wastewater treatment device is in use, the filter screen separates water and impurities, but the filtered water and the crushed impurities are discharged from the bottom of the treatment barrel together, resulting in poor filtering effect.
