The inner wall of the bottom of the shell 5 is provided with two converging grooves 16 for converging impurities, and the two converging grooves 16 are respectively located on both sides of the filter plate 17. A scraping component for cleaning the filter plate 17 and cleaning impurities out of the shell 5 is provided in the shell 5. The bottom of the shell 5 is located at the filter plate 1 A waste pipe 13 is welded at the position just below 7, and the butanediol production waste liquid is added into the box body 3, and then the chemicals for treating the butanediol production waste liquid are added into the box body 3, and then the reduction motor 6 drives the rotating frame 11 to rotate, and the rotating frame 11 drives the blades 10 to rotate, so that the blades 10 stir and mix the butanediol production waste liquid and the chemicals, so that the chemicals react with the butanediol production waste liquid to treat the organic impurities and heavy metals. After the treatment is completed, the closing component no longer closes the discharge pipe 8. At this time, the treated waste liquid in the box body 3 will be discharged into the shell body 5 through the discharge pipe 8. At this time, the filter plate 17 in the shell body 5 will filter the organic impurities and heavy metals remaining in the waste liquid, and the filtered waste liquid will be discharged through the waste pipe 13, thereby effectively removing the organic impurities and heavy metals in the waste liquid, while increasing the function of the treatment device and improving the use effect of the treatment device.

[0024] In the present invention, the closing assembly includes a cylinder 2 9, which is fixed to the outer wall of one side of the discharge pipe 8 by bolts. One end of the telescopic part of the cylinder 2 9 is fixed to a connecting frame by bolts, and one end of the connecting frame is welded with a lower baffle 7. A socket adapted to the lower baffle 7 is provided on one side of the discharge pipe 8. The lower baffle 7 is inserted into the discharge pipe 8 through the socket to close the discharge pipe 8. When the cylinder 2 9 is started to extend, the cylinder 2 9 will push the connecting frame to drive the lower baffle 7 to move, so that the lower baffle 7 no longer closes the discharge pipe 8. At this time, the waste liquid processed in the box 3 will be discharged into the shell 5 through the discharge pipe 8.

[0025] In particular, the scraping assembly includes two guide rods 14, and the two guide rods 14 are welded to positions on both sides of the shell 5. The outer sides of the two guide rods 14 are slidably connected with scraper frames 15, and the scraper frames 15 are in contact with the filter plate 17 and the gathering groove 16. A pull handle is welded at one end of the scraper frame 15, and the pull handle extends out of the shell 5.

The upper surface of the filter plate 17 is provided with two relatively distributed slopes 12, so that the filter plate 17 forms an inverted V shape. The organic impurities and heavy metals filtered out of the waste liquid by the filter plate 17 are formed into an inverted V shape under the action of the slope 12 on the surface of the filter plate 17, so that the organic impurities and heavy metals slide into the gathering groove 16, thereby converging the impurities. The scraper 15 is then pulled to move so that the scraper 15 can clean the impurities in the collection tank 16 out of the housing 5 through the waste outlet 20. At the same time, the scraper 15 can clean the impurities stuck in the filter holes, scrape the impurities out and make them slide into the collection tank 16, thereby cleaning the filter plate 17. A plurality of paddles 10 are staggered, and the paddles 10 are staggered so that the paddles 10 can better stir the waste liquid.

One end of the pneumatic rod of the cylinder 1 is rotatably connected to a connecting block, and the connecting block is fixed to the cover plate 2. The cover plate 2 can be opened or closed by the extension and contraction of the cylinder 1, so that the cover plate 2 can be automatically opened or closed.

[0026] The working principle of the present invention is as follows: when in use, the butanediol production waste liquid is added into the box body 3, and then the chemicals for treating the butanediol production waste liquid are added into the box body 3, and then the reduction motor 6 drives the rotating frame 11 to rotate, and the rotating frame 11 drives the blade 10 to rotate, so that the blade 10 stirs and mixes the butanediol production waste liquid and the chemicals, so that the chemicals react with the butanediol production waste liquid to treat organic impurities and heavy metals. After the treatment is completed, the cylinder 2 9 is started to extend, and the cylinder 2 9 will push the connecting frame to drive the lower baffle 7 to move, so that the lower baffle 7 no longer closes the discharge pipe 8. At this time, the waste liquid in the box body 3 is treated. It will be discharged into the shell 5 through the discharge pipe 8. At this time, the filter plate 17 in the shell 5 will filter the organic impurities and heavy metals remaining in the waste liquid, and the filtered waste liquid will be discharged through the waste pipe 13, so as to effectively remove the organic impurities and heavy metals in the waste liquid, and at the same time increase the function of the treatment device and improve the use effect of the treatment device. The organic impurities and heavy metals filtered out of the waste liquid by the filter plate 17 are formed into an inverted V shape under the action of the slope 12 on the surface of the filter plate 17, so that the organic impurities and heavy metals slide into the convergence tank 16, thereby converging the impurities, avoiding the accumulation of impurities on the filter plate 17, and improving the filtering effect of the filter plate 17.
