Description

Technical Field

[0001] This utility model belongs to the field of wastewater recycling treatment, and more specifically, it relates to a water recycling treatment device for the reuse of industrial wastewater. Background Technology

[0002] Industrial wastewater refers to wastewater and waste liquid generated during industrial production processes. It contains industrial raw materials, intermediate products, by-products, and pollutants lost during production. Because industrial wastewater often contains various toxic substances, it pollutes the environment and poses a significant threat to human health. Industrial wastewater reuse water recycling treatment devices are integrated technology systems that deeply treat and purify wastewater generated during industrial production processes, enabling the recycling of water resources. This device uses the synergistic effect of physical, chemical, and biological treatment processes to remove suspended solids, organic matter, heavy metal ions, salts, and microorganisms from the wastewater, ensuring that the treated water meets industrial reuse standards (such as cooling water, process water, or boiler feedwater). This reduces the consumption of fresh water resources and the discharge of industrial wastewater, achieving the dual goals of sustainable water resource utilization and environmental protection.

[0003] In current industrial production, existing industrial wastewater recycling and treatment devices exhibit a prominent problem during actual operation: the pumping pipes are highly susceptible to interference and blockage by sludge during wastewater extraction. Industrial wastewater often contains a large amount of impurities, especially complex and highly viscous sludge. This sludge continuously adheres to and accumulates inside the pumping pipes during the pumping process, gradually reducing the effective flow area and significantly lowering pumping efficiency. This severely impacts the normal operation and treatment performance of the entire wastewater recycling system. Utility Model Content

[0004] In view of the problems in the related technologies, this utility model proposes a water recycling treatment device for industrial wastewater reuse, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a water recycling treatment device for industrial wastewater reuse, comprising a wastewater treatment tank. A connecting plate and a first filter screen are movably installed inside the wastewater treatment tank, dividing it into a filtration tank, a sedimentation tank, and a clear water tank. A water pump is fixedly installed above the wastewater treatment tank, with a pumping pipe and a drain pipe connected to both ends of the pump. A first gear is rotatably mounted on the pumping pipe, and a filter screen is fixedly mounted on the first gear. The first gear meshes with a second gear, and the output end of a waterproof motor is fixedly mounted on the second gear. A cleaning brush is attached to the filter screen and fixedly mounted on the pumping pipe. The waterproof motor is also fixedly mounted on the pumping pipe.

[0007] Furthermore, a second filter screen is rotatably installed inside the filter tank. The bottom of the second filter screen abuts against the protruding end of the cam. The cam is fixedly installed on the connecting shaft, and the connecting shaft is rotatably installed inside the filter tank.

[0008] Furthermore, a first transmission wheel is fixedly mounted on the connecting shaft, and the output end of a drive motor is fixedly mounted on the first transmission wheel. The drive motor is fixedly mounted on the sewage treatment tank.

[0009] Furthermore, the first drive wheel is connected to the second drive wheel via a drive belt, and both the first drive wheel and the second drive wheel are rotatably mounted on the sewage treatment tank.

[0010] Furthermore, the second transmission wheel is fixedly mounted with a reciprocating threaded rod, which is rotatably installed inside the sewage treatment tank. The reciprocating threaded rod is threadedly connected to a cleaning brush. One end of the cleaning brush slides on the inner wall of the sewage treatment tank, and the other end is slidably connected to a connecting plate. The brush bristles are always in contact with the surface of the second filter screen. A discharge port is provided at the inclined end of the second filter screen. The discharge port is located on the sewage treatment tank, and a storage box is movably installed at the lower end of the discharge port.

[0011] Furthermore, a first drain outlet is provided at the bottom of the connecting plate, and a second drain outlet is provided at the end of the sewage treatment tank away from the first drain outlet.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model features a rotating filter screen installed at the inlet end of the water pumping pipe. Driven by a waterproof motor, the screen rotates and, in conjunction with a cleaning brush, continuously scrapes away impurities from its surface, effectively preventing clogging and ensuring a continuous and efficient flow of wastewater into the filtration tank. Simultaneously, a second filter plate vibrates via a cam mechanism, enhancing the filtration effect and further improving the efficiency and quality of wastewater treatment, providing a reliable guarantee for the reuse of industrial wastewater.

[0014] 2. This utility model is equipped with an automatic cleaning system. A transmission mechanism drives the cleaning brush to move back and forth along the surface of the second filter screen, promptly removing filter residue. The residue is then collected in a storage box through the discharge port, avoiding the tediousness of manual cleaning and secondary pollution. Furthermore, the device employs a graded treatment design with a filtration tank, sedimentation tank, and clear water tank. Through the separation effect of the connecting plate and the filter screen, wastewater passes through different treatment stages sequentially, ensuring that the final recovered clear water meets reuse standards, thus achieving the safe and efficient recycling of industrial wastewater.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] Please see Figures 1-6 As shown, this utility model is a water recycling treatment device for industrial wastewater reuse, including a wastewater treatment tank 1. A connecting plate 2 and a first filter screen 3 are movably installed inside the wastewater treatment tank 1. The connecting plate 2 and the first filter screen 3 divide the wastewater treatment tank 1 into a filter pool 4, a sedimentation pool 5, and a clear water pool 6. A water pump 7 is fixedly installed above the wastewater treatment tank 1. The two ends of the water pump 7 are connected to a pumping pipe 8 and a drain pipe 9. A first gear 10 is rotatably installed on the pumping pipe 8. A filter screen 11 is fixedly installed on the first gear 10. The first gear 10 meshes with a second gear 12. The output end of a waterproof motor 13 is fixedly installed on the second gear 12. A cleaning brush 14 is attached to the filter screen 11. The cleaning brush 14 is fixedly installed on the pumping pipe 8. The waterproof motor 13 is fixedly installed on the pumping pipe 8.

[0028] The working principle of the industrial wastewater recycling water treatment device proposed in this utility model is as follows: After the water pump 7 is started, the industrial wastewater to be treated is directly pumped into the filter tank 4 through the pumping pipe 8. A rotatable filter screen 11 is provided at the inlet end of the pumping pipe 8. This filter screen 11 is driven to rotate by a waterproof motor 13 fixed on the pumping pipe 8 through the meshing of a first gear 10 and a second gear 12. During the wastewater pumping process, a cleaning brush 14 fixed on the pumping pipe 8 continuously scrapes away impurities trapped on the surface of the rotating filter screen 11 to prevent clogging. After preliminary filtration, the wastewater enters the filter tank 4 and, through the separation effect of the connecting plate 2 and the first filter screen plate 3, flows sequentially through the sedimentation tank 5 for natural settling. Finally, the clear water enters the clear water tank 6 for storage. The entire device achieves efficient wastewater treatment and recycling through the rotary filtration and automatic cleaning system at the inlet end.

[0029] In one embodiment, for the above-mentioned filter pool 4, a second filter screen plate 15 is rotatably installed inside the filter pool 4. The bottom of the second filter screen plate 15 abuts against the protruding end of the cam 16. The cam 16 is fixedly installed on the connecting shaft 17, and the connecting shaft 17 is rotatably installed inside the filter pool 4.

[0030] In one embodiment, the connecting shaft 17 is fixedly mounted with a first transmission wheel 18, the first transmission wheel 18 is fixedly mounted with the output end of a drive motor 19, and the drive motor 19 is fixedly mounted on the sewage treatment tank 1.

[0031] In one embodiment, the first drive wheel 18 is connected to the second drive wheel 21 via a drive belt 20, and both the first drive wheel 18 and the second drive wheel 21 are rotatably mounted on the sewage treatment tank 1.

[0032] In one embodiment, for the second transmission wheel 21, a reciprocating threaded rod 22 is fixedly installed on the second transmission wheel 21. The reciprocating threaded rod 22 is rotatably installed inside the sewage treatment tank 1. A cleaning brush 23 is threadedly connected to the reciprocating threaded rod 22. One end of the cleaning brush 23 slides on the inner wall of the sewage treatment tank 1, and the other end is slidably connected to the connecting plate 2. The brush of the cleaning brush 23 is always in contact with the surface of the second filter screen plate 15. A discharge port 24 is provided at the inclined end of the second filter screen plate 15. The discharge port 24 is opened on the sewage treatment tank 1, and a storage box 25 is movably installed at the lower end of the discharge port 24.

[0033] In one embodiment, the connecting plate 2 has a first drain outlet 26 at its bottom and a second drain outlet 27 at the end of the sewage treatment tank 1 away from the first drain outlet 26.

[0034] The working principle of the industrial wastewater recycling water circulation treatment device proposed in this utility model is as follows: Pump 7 is started to draw external wastewater into the filter tank 4 through pumping pipe 8. The rotating filter screen 11 at the inlet end of pumping pipe 8 is driven to rotate by a waterproof motor 13 via a first gear 10 and a second gear 12. Simultaneously, a cleaning brush 14 removes impurities from the filter screen 11. After entering the filter tank 4, the wastewater flows through the second filter plate 15. The drive motor 19 drives the connecting shaft 17 to rotate via the first transmission wheel 18, causing the cam 16 to periodically lift the second filter plate 15, producing a vibration filtration effect. The first transmission wheel 18 drives the second transmission wheel 21 to rotate via the transmission belt 20, which in turn drives the reciprocating threaded rod 22 to rotate, causing the cleaning brush 23 to reciprocate along the surface of the second filter plate 15 to remove filter residue. The filter residue falls into the storage box 25 through the discharge port 24. The wastewater sequentially passes through the filter tank 4, sedimentation tank 5, and clear water tank 6. The first drain port 26 and the second drain port 27 at the bottom of the connecting plate 2 control the water flow direction, achieving graded treatment and clear water recycling.
