The inner walls of the waste box 1 3 and the waste box 2 4 are fixedly connected with a scraper 13 and a guide plate 15. The top end of the scraper 13 is slidably connected to the outer surface of the filter crawler net 12, and the bottom end of the guide plate 15 is slidably connected to the inner surface of the filter crawler net 12. The bottom end of the inner wall of the filter box 2 is provided with a sand and gravel layer 16, an activated carbon adsorption layer 17 and a nanofiltration layer 18, which can filter the coal chemical wastewater well.

[0027] Furthermore, the outer sides of the sand and gravel layer 16, the activated carbon adsorption layer 17 and the nanofiltration layer 18 are fixedly connected with a fixing plate 9, and a mounting groove is opened on the side of the filter box 2. The side of the fixing plate 9 is movably inserted into the inner wall of the mounting groove, so as to facilitate the replacement operation of the sand and gravel layer 16, the activated carbon adsorption layer 17 and the nanofiltration layer 18.

[0028] Furthermore, a baffle 11 is fixedly connected through the top of the filter box 2, and the side of the filter crawler net 12 is slidably connected to the inner side of the two baffles 11, which blocks the wastewater so that the wastewater can only fall onto the filter crawler net 12 for filtering.

[0029] Furthermore, recycling ports are provided on the sides of waste box 1 3 and waste box 2 4, and the inner wall of the recycling port is rotatably connected to a fixed shaft 19, and a recycling bin door 7 is fixedly connected to the surface of the fixed shaft 19, and a handle 8 is fixedly connected to the side of the recycling bin door 7, which facilitates the cleaning of the coal slag particles collected in waste box 1 3 and waste box 2 4.

Since the top of the scraper 13 is attached to the outer surface of the filter crawler net 12, the impurity particles on the outer surface of the filter crawler net 12 will be scraped off by the scraper 13, and then fall into the waste box 3 along the inclined surface of the scraper 13 for collection. Since the filter crawler net 12 is a double-layer design, the inner side of the filter crawler net 12 may also be blocked by particles when it is in operation. The particles will be scraped off by the guide plate 15 inside the waste box 13, and the scraper 13 and the guide plate 15 inside the waste box 2 4 will perform a secondary scraping operation on the outer surface of the filter crawler net 12. Since the guide plate 15 is a slanted U-shaped design, the scraped particles and debris will be blocked by the guide plate 15. When there are a lot of accumulated debris, they will be discharged along the inner wall of the guide plate 15 on both sides, and then fall into the waste box 1 3 or the waste box 2 4 for collection. The design of the baffle 11 will block the wastewater, so that the wastewater can only fall on the filter crawler net 12 for filtering. The wastewater that has initially filtered out the particles is filtered through the sand and gravel layer 16, the activated carbon adsorption layer 17 and the nanofiltration layer 18, and then discharged through the outlet pipe 10.
