[0002] Industrial wastewater refers to wastewater, sewage, and waste liquid generated during industrial production processes. It contains industrial raw materials, intermediate products, and finished products lost with the wastewater, as well as pollutants generated during production. This wastewater has a complex composition and may contain organic matter, inorganic matter, heavy metals, and other pollutants. The degree and quantity of pollution depend on factors such as production materials, technology, water quality, and recovery rate. The treatment of industrial wastewater is crucial for protecting the environment and water resources, as improper discharge can have a significant impact on freshwater and threaten human health and safety. Solid-liquid separation is one of the key steps in industrial wastewater treatment, its main purpose being to remove solid matter from the wastewater to improve its treatability and reuse value.

[0003] In industrial wastewater treatment, solid-liquid separation is a crucial step in ensuring the efficiency of subsequent treatment. However, existing separation equipment still suffers from numerous technical shortcomings in practical applications. Traditional devices mostly employ static filtration methods, lacking active sludge removal mechanisms. This leads to the easy accumulation and clogging of solid impurities on the filter screen, drastically reducing filtration efficiency and requiring frequent shutdowns for disassembly and cleaning, severely impacting continuous treatment capacity and significantly increasing manual maintenance costs. Furthermore, existing equipment often struggles to effectively intercept and transport large particulate impurities or fibrous and strip-shaped pollutants in wastewater, easily resulting in impurities becoming stuck in the filter screen. Therefore, we propose a solid-liquid separation device to address these issues. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Depend on Figures 1-4 As shown, a solid-liquid separation device is disclosed, comprising a separation chamber 1, a frame 2 fixedly connected to the outer wall of the separation chamber 1, a geared motor 3 fixedly connected inside the frame 2, multiple heat dissipation holes on the outer wall of the frame 2, a through hole on the outer wall of the separation chamber 1, the inner wall of the through hole being rotatably connected to the outer wall of the output shaft of the geared motor 3, an end plate 4 fixedly connected to one end of the output shaft of the geared motor 3, and an annular filter screen 5 fixedly connected to the outer wall of the end plate 4. The annular filter screen 5 achieves dynamic filtration by rotation, which, compared with a static filter screen, can reduce the accumulation and clogging of impurities and improve filtration efficiency.

[0024] The geared motor 3 drives the end plate 4 and the annular filter screen 5 to rotate. The outer wall of the annular filter screen 5 is fitted with two support plates 6. The outer walls of the two support plates 6 are fixedly connected to the inner wall of the separation box 1. A baffle 13 is fixedly connected to the outer wall of one support plate 6. A drain pipe 14 is fixedly connected to the outer wall of the separation box 1. Two legs 15 are fixedly connected to the bottom of the separation box 1.

[0025] The outer walls of the separation box 1 and the other support plate 6 are provided with mounting holes. The inner walls of the mounting holes are fixedly connected to the water outlet pipe 16. The bottom of the water outlet pipe 16 is uniformly connected to the fan-shaped nozzles 17. The fan-shaped nozzles 17 are located on the top of the annular filter screen 5 and can spray the water transported by the water outlet pipe 16 in a fan shape. The water flow covers a wide range and can use the impact force to wash down the impurities on the annular filter screen 5 and the toothed scraper 7. One end of the water outlet pipe 16 is fixedly connected to the water pump.

[0026] The annular filter 5 has a collection component inside, which includes an arc plate 8. Multiple toothed scrapers 7 are uniformly fixed to the inner wall of the annular filter 5. As the annular filter 5 rotates, the toothed scrapers 7 can scrape up the solid impurities trapped on the annular filter 5 and transport them to the top of the receiving frame 10, thus preventing impurities from accumulating on the surface of the annular filter 5.

[0027] The inner wall of the separation box 1 is fixedly connected to one end of the arc plate 8. Multiple triangular blades 9 are evenly fixedly connected to the top of the arc plate 8. When the toothed scraper 7 drives the impurities to rotate and pass through, the triangular blades 9 can cut the impurities, breaking larger solid impurities into smaller pieces, making it easier for the impurities to fall off. At the same time, by contacting the impurities, the impurities attached to the toothed scraper 7 can be removed, enhancing the impurity cleaning effect. The end plate 4, the annular filter screen 5, the support plate 6, the toothed scraper 7, the arc plate 8, the triangular blades 9 and the receiving frame 10 are all made of stainless steel.

[0028] The outer wall of the separation box 1 has a rectangular hole, and a receiving frame 10 is fixedly connected to the inner wall of the rectangular hole. One end of the receiving frame 10 is located inside the annular filter screen 5. A drain pipe 11 is fixedly connected to the bottom of the receiving frame 10, which can discharge the solid impurities and a small amount of water collected in the receiving frame 10, so as to realize the separate collection and treatment of solid impurities. A sewage inlet pipe 12 is fixedly connected to the outer wall of the separation box 1, and a pump body is fixedly connected to one end of the sewage inlet pipe 12.

[0029] Working principle: During operation, sewage is pumped into the separation tank 1 through the pump body and inlet pipe 12. The sewage is shielded by the left support plate 6 and flows through the annular filter screen 5. Solid impurities larger than the screen aperture diameter of the annular filter screen 5 are trapped by the filter. The filtered sewage is discharged through the drain pipe 14. As the reduction motor 3 operates, it drives the end plate 4 and the annular filter screen 5 to rotate. The rotation of the annular filter screen 5 drives the multiple toothed scrapers 7 arranged in a ring inside to rotate. Through the rotation of the toothed scrapers 7, solid impurities are carried to the top of the receiving frame 10 and, with their own rotation... The weight falls into the receiving frame 10, while the solid impurities that do not fall are cut and touched by the multiple triangular blades 9 on the top of the arc plate 8 as the multiple toothed scrapers 7 rotate. The water pump delivers external water to the inside of the outlet pipe 16 and sprays it downward from the bottom of the multiple fan-shaped nozzles 17. The multiple fan-shaped nozzles 17 are located on the top of the annular filter screen 5. Through the impact of the water flow and the cutting of the multiple triangular blades 9, the solid impurities fall into the receiving frame 10. The solid impurities and water in the receiving frame 10 are discharged downward from the drain pipe 11 and collected separately.

[0030] It should be noted that when actually put into use, an existing PLC controller can be added. The PLC controller is electrically connected to the geared motor 3, the pump body, and the water pump to facilitate the control of the overall operation.

[0031] All standard parts used in this utility model can be purchased from the market. Irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. Furthermore, the structure and principle of the components known to those skilled in the art can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0032] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
