Description

Technical Field

[0001] This utility model relates to wastewater treatment technology, and more particularly to a sludge reduction and resource recovery co-processing device. Background Technology

[0002] Wastewater often contains silt and sand, requiring sedimentation and filtration for further purification. However, during filtration, silt and sand adhere to the surface of the filter plate, leading to sediment buildup that hinders wastewater discharge and clogs the filter pores, interfering with normal drainage. Directly scraping with a scraper not only increases sludge accumulation at the edges and corners, hindering sediment settling, but also allows larger silt deposits to be easily washed away by the water flow, reducing filtration efficiency.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] like Figures 1 to 8 As shown, this utility model's sludge reduction and resource recovery co-processing device includes a filter tank 1, a baffle 2, a filter plate 3, and a scraper 4. The baffle 2 is located inside the filter tank 1, and the filter plate 3 is located on the baffle 2. The scraper 4 is used to scrape off the sludge on the filter plate 3, preventing the filter holes 5 from becoming clogged due to excessive sludge accumulation. The scraped sludge can be collected through a deep water storage chamber 6 without affecting the sedimentation of sludge or the flow direction of water.

[0027] A water storage chamber 6 is formed in the middle of the filter tank 1. A fixing member 7 is provided on the outside of the filter tank 1, and an inlet pipe 8 is located in the middle of the fixing member 7. The inlet pipe 8 is used to transport the wastewater to be filtered. A drain pipe 9 and a sludge discharge pipe 10 are provided at the lower end of the filter tank 1. The drain pipe 9 is used to discharge the filtered wastewater, and the sludge discharge pipe 10 is used to clean the sludge that has settled in the water storage chamber 6. An activated carbon plate 11 is located in the middle of the drain pipe 9, and a plug 12 is located inside the sludge discharge pipe 10. When cleaning the sludge, the plug 12 is removed to discharge the sludge.

[0028] The lower end of the drain pipe 9 is provided with symmetrically arranged hinge blocks 13, the middle of which is provided with a hinge rod 14, and the lower end of the hinge rod 14 is provided with a stop rod 15, which is located at the lower end of the activated carbon plate 11. By rotating the stop rod 15, the stop rod 15 can support the activated carbon plate 11. When replacement is required, the stop rod 15 is rotated again so that it no longer supports the activated carbon plate 11, and the activated carbon plate 11 can be removed and replaced.

[0029] Baffle 2 is installed inside water storage chamber 6, and a drainage channel 16 is formed between baffle 2 and the inner wall of water storage chamber 6. Wastewater filtered by filter plate 3 enters the drainage channel 16. Filter plate 3 is provided at the upper end of drainage channel 16. Filter plate 3 has multiple filter holes 5. Filter holes 5 can filter larger soil and gravel, which are then filtered again by activated carbon plate 11 at the lower end.

[0030] The filter plate 3 is inclinedly hinged to the baffle 2. The baffle 2 is provided with a limiting part 17, and the limiting part 17 is provided with a hinge interface 18, which faces away from the end away from the drainage channel 16. The filter plate 3 is provided with a hinge end 19, which is located in the hinge interface 18. The hinge end 19 is also provided with an arc-shaped clearance 20 that cooperates with the limiting part 17. When installing the filter plate 3, the hinge end 19 is first placed vertically, and then moved horizontally so that the hinge end 19 is placed in the hinge interface 18. Then, it is rotated around the hinge interface 18 as the center, so that the filter plate 3 is placed in an inclined state on the inner wall of the water storage chamber 6.

[0031] A scraper 4 is provided on the end of the filter plate 3 away from the baffle 2, and the scraper 4 contacts the inner wall of the water storage chamber 6. The scraper 4 consists of a vertical plate 21 and a horizontal plate 22. The lower end of the vertical plate 21 has an inclined surface 23 that cooperates with the inclined filter plate 3, so that the scraper 4 scrapes the sludge on the filter plate 3 through the inclined surface 23. Since sewage can be discharged through the filter holes 5, the sewage can flush the filter holes 5. The scraper 4 prevents sludge from accumulating on the filter plate 3, thereby affecting the discharge of sewage.

[0032] The filter plate 3 is provided with a blocking groove 24, and the lower end of the scraper 4 is disposed in the blocking groove 24. The bottom surface of the blocking groove 24 is lower than the upper end surface 25 of the filter plate 3, thereby restricting the position of the scraper 4 through the blocking groove 24.

[0033] The filter tank 1 is provided with symmetrically arranged sliding seats 26, with a sliding groove 27 in the middle of the sliding seat 26. One end of the sliding seat 26 is provided with a positioning block 28, and the positioning block 28 is provided with a sliding rod 29 located in the sliding groove 27. A first spring 30 is sleeved on the sliding rod 29. One end of the first spring 30 contacts the sliding block 31, and the other end contacts the positioning block 28.

[0034] The movable seat 32 is located between the upper ends of the symmetrically arranged sliding seats 26. The lower end of the movable seat 32 is provided with a sliding block 31 that cooperates with the sliding groove 27. The sliding block 31 slides within the sliding groove 27. The middle of the sliding block 31 is provided with a sliding hole 33 that cooperates with the sliding rod 29. The sliding hole 33 is a strip-shaped hole. The height of the sliding hole 33 is greater than the diameter of the sliding rod 29. The gap left by the height of the sliding hole 33 minus the diameter of the sliding rod 29 is greater than the depth of the blocking groove 24, so that the scraper 4 can be moved out of the blocking groove 24. This allows the scraper 4 to be kept on the upper end face 25 of the filter plate 3 to scrape the sludge on its upper end face 25.

[0035] A guide rod 34 is provided on the scraper component 4. The lower end of the guide rod 34 extends through the movable seat 32 to the lower end. A second spring 35 is sleeved on the guide rod 34, and the second spring 35 is located between the scraper component 4 and the movable seat 32. A nut 36 is provided at the upper end of the guide rod 34, and a thread that mates with the nut 36 can be provided at the upper end of the guide rod 34. The nut 36 is located on the transverse plate 22. A first through hole 37 is provided on the transverse plate 22, and a second through hole 38 is provided on the movable seat 32. The guide rod 34 is located in the first through hole 37 and the second through hole 38, and can move up and down within the first through hole 37 and the second through hole 38.

[0036] When it is necessary to scrape the sludge off the filter plate 3, first lift the scraper 4 upwards so that the guide rod 34 moves within the sliding hole 33. Here, the position of the sliding hole 33 changes, while the position of the guide rod 34 moves relative to it and does not actually move.

[0037] Then, pressure is applied downwards to the scraper 4, compressing the second spring 35 and pushing the scraper 4 to compress the first spring 30, causing the scraper 4 to scrape along the inclined surface of the filter plate 3, removing the sludge from the surface of the filter plate 3. After scraping is complete, the applied external force is released, and the scraper 4 can be reset under the elastic force of the first spring 30 and the second spring 35, re-entering the blocking groove 24 to restrict the position of the scraper 4.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
