Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment, specifically a wastewater treatment device with high treatment efficiency. Background Technology

[0002] Wastewater refers to polluted wastewater from domestic and industrial processes. Water that has lost its original function is simply called wastewater, primarily water used for domestic purposes. It contains a high amount of organic matter and is relatively easy to treat. Sedimentation is a crucial step in wastewater treatment. However, before sedimentation, chemicals need to be added and mixed with the wastewater to achieve better sedimentation results. Mixing and stirring are generally done manually, which is time-consuming, labor-intensive, and physically demanding. Furthermore, wastewater contains large particles that occupy significant space during sedimentation, reducing treatment efficiency. Patent CN214400079U, entitled "A Wastewater Treatment Device with High Treatment Efficiency," discloses a treatment device that sprays chemicals into a mixing tank, a stirring mechanism agitates the wastewater, and the mixture flows through an outlet pipe into a sedimentation tank for sedimentation. A pumping pipe then moves above the sediment to remove the clear water, leaving the precipitated impurities. However, the filter plate angle is fixed during use and cannot be adjusted according to the solids content of the wastewater. Therefore, we have made further improvements and designed a wastewater treatment device with high treatment efficiency. Utility Model Content

[0003] This invention provides a wastewater treatment device with high treatment efficiency to overcome the deficiencies in the prior art.

[0004] This utility model is achieved through the following technical solution:

[0005] A high-efficiency wastewater treatment device includes a tank with several supporting legs fixedly mounted on the bottom side and an inlet pipe fixedly connected to the top side of the tank. The tank contains a filter screen, a water guide platform, a mixing tank, and a sedimentation tank. A filter screen is fixedly mounted on the filter screen, which is rotatably installed on a drain outlet on one side of the tank.

The fixed ends of the telescopic rods are mounted on the chute via electric push rods, and the movable ends of the telescopic rods are rotatably mounted on the filter screen. A baffle is installed above the other side of the filter screen.

[0006] As described above, a wastewater treatment device with high treatment efficiency has several spherical grooves on the filter screen plate, and spherical blocks are rotatably installed in each of the spherical grooves. The spherical blocks are fixedly connected to the movable ends of the corresponding telescopic rods through connecting rods.

[0007] As described above, a wastewater treatment device with high treatment efficiency has several high-pressure nozzles fixedly connected to the housing. The high-pressure nozzles are inclined and face the bottom of the filter screen. A water pump is fixedly installed on the housing.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] A wastewater treatment device with high treatment efficiency, such as Figure 1 , 2As shown in Figure 3, the device includes a housing 1. Several support legs 2 are fixedly installed on the bottom side of the housing 1. A water inlet pipe 3 is fixedly connected to the top side of the housing 1. Inside the housing 1, there is a filter screen plate 4, a water guide platform 13, a mixing tank 5, and a sedimentation tank 6. A filter screen 7 is fixedly installed on the filter screen plate 4. The filter screen plate 4 is rotatably installed on a drain outlet 8 opened on one side of the housing 1. One side of the filter screen 4 is rotatably installed on the drain outlet 8 through a hinge shaft. A sliding groove 9 is opened on the other side of the housing 1. Several telescopic rods 10 are slidably installed on the sliding groove 9. A first sliding groove is opened on the sliding groove 9. The fixed end of the telescopic rod 10 is slidably installed on the first sliding groove. The fixed end of the telescopic rod 10 is respectively installed on the sliding groove 9 through an electric push rod 11. The fixed end of the electric push rod 11 is fixedly installed on the sliding groove 9. The movable end of the electric push rod 11 is fixedly connected to the fixed end of the telescopic rod 10. The movable end of the telescopic rod 10 is rotatably installed on the filter screen plate 4. A baffle 12 is installed on the upper side of the other side of the filter screen plate 4. This utility model has a simple structure and ingenious design. The tilt angle of the filter screen plate 4 is adjustable. When the solid content of the sewage is high, the tilt angle of the filter screen plate 4 is increased to accelerate the sludge sliding and prevent the filter holes from clogging. When the solid content of the sewage is low, the tilt angle of the filter screen plate 4 is decreased to extend the filtration time and ensure that the liquid fully penetrates. It is easy to operate, meets market demand, and is suitable for promotion. When using this utility model, the tilt angle of the filter screen plate 4 is adjusted appropriately according to the solid content of the wastewater to be treated. When it is necessary to increase the tilt angle of the filter screen plate 4, the electric push rod 11 is extended by controlling the electric push rod 11 to drive the telescopic rod 10 to move upward, and the filter screen plate 4 rotates upward to drive the telescopic rod 10 to extend. Conversely, when it is necessary to decrease the tilt angle of the filter screen plate 4, the electric push rod 11 is shortened by controlling the electric push rod 11 to drive the telescopic rod 10 to move downward, and the filter screen plate 4 rotates downward to drive the telescopic rod 10 to shorten. The telescopic rod 10 slides on the slide groove 9. The wastewater is introduced into the tank 1 through the inlet pipe 3. The baffle 12 can prevent the wastewater from flowing back to the right. The wastewater first passes through the filter screen 7 for the first filtration, and then falls into the mixing tank 5 through the guide platform 13. By spraying the medicine into the mixing tank 5, the stirring mechanism stirs the wastewater in the mixing tank 5. After mixing, it is discharged into the sedimentation tank 6 below for sedimentation.

[0017] Specifically, as shown in the figure, the filter plate 4 in this embodiment has several spherical grooves 20, and spherical blocks 21 are rotatably disposed in each of the spherical grooves 20. The spherical blocks 21 are fixedly connected to the movable ends of the corresponding telescopic rods 10 via connecting rods 22. When the filter plate 4 moves downward, it will squeeze the telescopic rods 10, and the telescopic rods 10 will cause the spherical blocks 21 to rotate relative to the spherical grooves 20. The spherical grooves 20 can prevent the spherical blocks 21 from sliding out.

[0018] Specifically, as shown in the figure, in this embodiment, several high-pressure nozzles 30 are fixedly connected to the housing 1. The high-pressure nozzles 30 are inclined and face the bottom of the filter screen 7. A water pump 31 is fixedly installed on the housing 1. The input end of the water pump 31 is connected to the sedimentation tank 6 through a water pipe 32, and the output end of the water pump 31 is also connected to the input end of the high-pressure nozzles 30 through a water pipe 32. The water pump 31 can recycle the treated water in the sedimentation tank 6 and backwash the filter screen 7 through the high-pressure nozzles 30 to prevent the filter screen 7 from becoming clogged and thus affecting the filtration efficiency.

[0019] Furthermore, as shown in the figure, a brush 40 is fixedly provided on the bottom side of the baffle 12 in this embodiment. The brush 40 slides in contact with the surface of the filter screen 7. Hidden grooves 41 are respectively opened on the front and rear sides of the filter screen plate 4. A rotating screw 42 is installed in one of the hidden grooves 41, and a nut 43 is threadedly installed on the screw 42. One end of the screw 42 is fixedly connected to the rotating shaft of the motor 44 and is coaxially arranged. The motor 44 is fixedly installed in the second hidden groove 45 opened in the filter screen plate 4. A sliding rod 46 is fixedly provided in the other hidden groove 41, and a sliding sleeve 47 is slidably installed on the sliding rod 46. The baffle 12 is fixedly installed on the nut 43 and the sliding sleeve 47. The rotating shaft of the motor 44 can drive the screw 42 to rotate, and the screw 42 can drive the nut 43 to move to the left or right. The nut 43 drives the sliding sleeve 47 to slide on the sliding rod 46 through the baffle 12. The left and right movement of the brush 40 can cooperate with the high-pressure nozzle 30 to clean the filter screen 7 and prevent the filter screen holes from being blocked.

[0020] Furthermore, as shown in the figure, in this embodiment, a cover plate 50 is slidably provided on the outer side of the drain outlet 8, and a second electric push rod 51 is fixedly provided on the housing 1. The movable end of the second electric push rod 51 is fixedly connected to the cover plate 50. The second electric push rod 51 can drive the cover plate 50 to block the drain outlet 8.

[0021] Furthermore, as shown in the figure, a controller 60 is fixedly installed on the housing 1 in this embodiment. The controller 60 is electrically connected to the electric push rod 11, the water pump 31, and the second electric push rod 51. The controller 60 can control the start and stop of the electric push rod 11, the water pump 31, and the second electric push rod 51.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
