Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly becoming a part of the daily lives of ordinary people.
[0003] Existing wastewater treatment technologies have the following drawbacks: during continuous wastewater filtration, the filter components intercept a large number of impurities, which can easily clog the filter components. Furthermore, the large number of intercepted impurities requires manual shutdown for maintenance. PP cotton and other filter components also intercept a large number of suspended impurities after prolonged use, necessitating shutdown for replacement. Therefore, improvements are needed to address these issues. Utility Model Content

[0020] Specifically, the chip conveyor 2 is equipped with a motor a1, and the output end of the motor a1 is fixedly connected to a conveying shaft 11. When the motor a1 rotates, it drives the conveying shaft 11 to rotate, which can move the impurities at the screen 4 upward.
[0021] Specifically, the chip rack 2 has a discharge port 15, through which impurities in the chip rack 2 fall into the collection box 13. The discharge port 15 is located above the collection box 13. A fine filter screen 14 is installed in the collection box 13, which can filter the impurities falling into the collection box 13.
[0022] Specifically, the collection tank 13 is interconnected with the sewage pump 12. The sewage pump 12 draws sewage from the collection tank 13 and transports it back into the tank body 5. The outlet of the sewage pump 12 extends into the interior of the tank body 5.
[0023] Specifically, a screen 4 is installed inside the housing 5. The screen 4 is installed at an angle between the housing 5 and the partition 23. The partition 23 is installed on the right side of the screen 4. A motor e22 is installed on the partition 23. A waterproof shell is provided on the outside of the motor e22. A screw a3 is fixedly connected to the output end of the motor e22. A scraper a16 is threadedly connected to the screw a3. The rotation of the screw a3 causes the scraper a16 to slide left and right.
[0024] Specifically, a motor c8 is installed at the top of the housing 5.

The output end of the motor c8 is fixedly connected to the screw b20, and the screw b20 is threadedly connected to the scraper b18.
[0025] Example 2: Please refer to Figure 1-4 The difference between this embodiment and embodiment 1 is that: the winding box 6 is equipped with a motor b7, the winding box 6 is installed on the outside of the box body 5, the output end of the motor b7 is fixedly connected to the winding roller 25, the rotation of the motor b7 drives the connected winding roller 25 to rotate for winding; the unloading box 10 is equipped with a motor d9, the unloading box 10 is installed on the outside of the box body 5, the output end of the motor d9 is fixedly connected to the unloading roller 24, the rotation of the motor d9 drives the connected unloading roller 24 to rotate for unloading.
[0026] In use, a chip removal frame 2 is installed on the left side of the housing 5. The screen 4 installed inside the housing 5 and partition 23 is inclined. The motor a1 on the chip removal frame 2 rotates, driving the conveying shaft 11 to rotate, which can transport the impurities intercepted on the screen 4 upward into the chip removal frame 2. The chip removal frame 2 is slightly higher than the water level at the screen 4. Some of the wastewater in the impurities flows back into the housing 5, and some wastewater enters the chip removal frame 2 with the impurities and falls into the collection box 13 through the discharge port 15. The wastewater flows through the fine filter screen 14 to the bottom of the collection box 13, and is then pumped back to the area above the screen 4 in the housing 5 by the wastewater pump 12. The motor e22 on the partition 23 rotates forward or backward, driving the connected screw a3 to rotate. The rotation of the screw a3 drives the scraper a16 to slide along the screen 4, which can scrape the surface of the screen 4 to prevent it from clogging. The wastewater after being screened by the screen 4 is located between the housing 5 and the partition 23. The water pump 17 is started to draw the wastewater and send it to the right side of the partition 23, where it mixes with the PP cotton 2. 1. Contact filtration: The PP cotton 21 and activated carbon cotton 19 have the same structure. The motor c8 at the top of the housing 5 rotates in both directions, driving the connected screw b20 to rotate. The rotation of the screw b20 causes the scraper b18 to slide up and down, scraping the surfaces of the PP cotton 21 and activated carbon cotton 19 to prevent impurities from clogging. After continuous filtration for a certain period of time, the motor d9 on the discharge box 10 rotates, driving the connected discharge roller 24 to release the PP cotton 21. At the same time, the motor b7 in the winding box 6 rotates, driving the connected winding roller 25 to wind up the PP cotton 21, thus replacing the PP cotton 21 in the housing 5 and allowing it to continuously filter wastewater. Similarly, the discharge roller 24 in the discharge box 10 corresponding to the activated carbon cotton 19 rotates to release the activated carbon cotton 19, and the winding roller 25 in the winding box 6 winds up the activated carbon cotton 19, thus replacing the activated carbon cotton 19. This allows for continuous filtration of wastewater without stopping the machine.
