Description

Technical Field

[0001] This utility model is a wastewater purification device, belonging to the field of wastewater purification technology. Background Technology

[0002] Wastewater purification is a core component of controlling water pollution and realizing the recycling of water resources. It is widely used in the treatment of domestic sewage, industrial wastewater (such as food processing and dyeing), and agricultural tailwater. In wastewater treatment, some chemical reagents are usually added to cause precipitation or flocculation, and then the sediment in the water is filtered out. If the filtration time is long, fixed substances will accumulate on the filter plate.

[0003] Chinese patent CN220424763U discloses a wastewater filtration environmental protection device. This device incorporates a precision filtration structure, enabling direct precision purification of pre-filtered wastewater. The integrated structure eliminates the need to transfer the pre-purified wastewater, saving transportation costs. It also features interlocking multi-stage filter plates, allowing for layer-by-layer filtration during the initial wastewater purification process and facilitating installation and disassembly. However, after each filter plate has been used, it requires manual removal for cleaning, a redundant step that detracts from its practicality. There is an urgent need for a wastewater purification device to address these issues. Utility Model Content

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1-5This utility model provides a technical solution: a sewage purification device, including a sewage purification tank 1 and a centralized treatment tank 14. Inside the sewage purification tank 1, a coarse-pore filter plate 2, a medium-pore filter plate 3, and a fine-pore filter plate 4 are horizontally installed from top to bottom via multiple bolts. A bending seat 5 is fixed to the right end of the sewage purification tank 1. An electric push rod 6 is horizontally installed inside the bending seat 5 via a flange and bolts. A push plate 7 is installed at the movable end of the electric push rod 6. Conical scrapers 9 are longitudinally arranged on the upper right side of the coarse-pore filter plate 2, the medium-pore filter plate 3, and the fine-pore filter plate 4. Push rods 8 are connected to the right ends of the three conical scrapers 9. Spring grooves 10 are opened at the lower ends of the three conical scrapers 9. Springs 11 are longitudinally installed in the three spring grooves 10. Spring plates 12 are installed at the lower ends of the three spring plates 12. Brushes 13 are connected to the lower ends of the three spring plates 12. The centralized treatment tank 14 is fixed to the sewage purification tank. At the left end of the water purification tank 1, three stepped grooves 23 are provided through the connection between the centralized treatment tank 14 and the sewage purification tank 1. Each of the three stepped grooves 23 has a sealing rubber frame 25 and a magnet frame 24 embedded in its left end. An electric telescopic rod 20 is horizontally installed inside the left end of the centralized treatment tank 14 via flanges and bolts. A connecting plate 21 is installed at the movable end of the electric telescopic rod 20. The right end of the connecting plate 21 is fixed to the three stepped clamping plates 22 via flanges and bolts. A forward and reverse motor 16 is installed on the lower rear side of the centralized treatment tank 14. A threaded rod 17 is installed inside the centralized treatment tank 14. A semi-circular scraper 19 is fixed to the shaft end of the forward and reverse motor 16 and the outside of the threaded rod nut sleeve 18. This design solves the problem that in the original sewage filtration environmental protection equipment, after each filter plate is used, the staff needs to remove the filter plates for cleaning, which is a redundant step and its practicality needs to be improved.

[0022] In the first embodiment of this utility model: three push rods 8 slide through the right side of the sewage purification tank 1, and the left end of the push plate 7 is fixed to the three push rods 8. A drain pipe is installed at the lower right end of the sewage purification tank 1. The three push rods 8 slide through the right side of the sewage purification tank 1, and the left end of the push plate 7 is fixed to the three push rods 8. When the electric push rod 6 is started, the three push rods 8 can be moved synchronously by the push plate 7. The front and rear ends of the three conical scrapers 9 slide against the inner wall of the sewage purification tank 1. When the three conical scrapers 9 move to the left, the impurities intercepted and filtered on the coarse-pore filter plate 2, the medium-pore filter plate 3, and the fine-pore filter plate 4 can be pushed to the left. Three brushes 13 are respectively positioned to abut against the upper right side of the coarse-pore filter plate 2, the medium-pore filter plate 3, and the fine-pore filter plate 4. These brushes clean impurities from the filter holes of the three plates. A discharge trough 15 is provided on the lower front side of the centralized processing box 14 to facilitate the discharge of impurities collected within the box.

[0023] Three stepped retaining plates 22 are respectively inserted into three stepped grooves 23 and are magnetically attracted to three magnet frames 24. The stepped surfaces of the three stepped retaining plates 22 pass through three sealing rubber frames 25. When not in use, the three stepped grooves 23 can be tightly sealed to prevent leakage. A semi-circular scraper 19 slides below the interior of the centralized treatment box 14. As the added semi-circular scraper 19 moves forward below the interior of the centralized treatment box 14, it can push out impurities from the centralized treatment box 14 through the discharge groove 15.

[0024] As a second embodiment of this utility model: In use, sewage passes sequentially through the coarse-pore filter plate 2, the medium-pore filter plate 3, and the fine-pore filter plate 4. The coarse-pore filter plate 2, the medium-pore filter plate 3, and the fine-pore filter plate 4 intercept and filter impurities of different sizes in the sewage. After the coarse-pore filter plate 2, the medium-pore filter plate 3, and the fine-pore filter plate 4 have been used for a long time, the electric push rod 6 is activated. The movable end of the electric push rod 6 drives the three push rods 8 to move to the left through the push plate 7, which in turn pushes the three conical scrapers 9 to move to the left on the upper surface of the coarse-pore filter plate 2, the medium-pore filter plate 3, and the fine-pore filter plate 4. When the three conical scrapers 9 move to the left, they can intercept and filter impurities on the coarse-pore filter plate 2, the medium-pore filter plate 3, and the fine-pore filter plate 4. The impurities are pushed to the left, and the three brushes 13 can push and rub the impurities in the filter holes of the coarse-pore filter plate 2, the medium-pore filter plate 3, and the fine-pore filter plate 4. Then, the movable end of the electric telescopic rod 20 is controlled to retract, which can drive the three step clamping plates 22 to fall off the three step grooves 23 through the connecting plate 21 until the impurities on the coarse-pore filter plate 2, the medium-pore filter plate 3, and the fine-pore filter plate 4 are pushed into the centralized processing box 14. Then, the forward and reverse motor 16 is started, which drives the threaded rod 17 to rotate in place. The nut sleeve 18 drives the semi-circular scraper 19 to slide forward at the lower end inside the centralized processing box 14 through the thread principle. During this process, the semi-circular scraper 19 can push the impurities in the centralized processing box 14 out through the discharge groove 15.
