Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater filtration device. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly becoming part of everyday life. Classified by wastewater source, wastewater treatment is generally divided into industrial wastewater treatment and domestic wastewater treatment. Industrial wastewater includes industrial wastewater, agricultural wastewater, and medical wastewater, while domestic wastewater is wastewater generated in daily life, referring to a complex mixture of various forms of inorganic and organic matter. Existing wastewater treatment plants require filtering solid impurities from the wastewater, but cleaning the filter screens necessitates pausing the filtration equipment, thus reducing its efficiency. Therefore, we propose a wastewater filtration device. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a wastewater filtration device. This invention solves the problem that existing wastewater treatment plants require filtering solid impurities from wastewater, but cleaning the filter screen necessitates pausing the filtration equipment, thus reducing its efficiency.

[0004] This utility model discloses a wastewater filtration device, including four support legs. The upper part of the four support legs is fixedly connected to a filter tank. A fixed plate is provided on one side of the upper end of the filter tank. Columns are provided on both sides above the fixed plate. The upper parts of two of the columns are fixedly connected to a top plate. A support frame is provided in the middle of the upper part of the top plate. A mounting frame is provided on the side of the support frame near the filter tank. A motor is fixedly mounted on the mounting frame. A gear is provided on the rotating shaft of the motor. A movable plate is provided on one side of the mounting frame. A rack that meshes with the gear is provided on the movable plate. The lower part of the movable plate is fixedly connected to a fixed frame. A filter screen frame is provided below the fixed frame.

[0005] In the above scheme, the support frame is provided with two symmetrical sliders on the side near the movable plate, and the movable plate is provided with guide rails that match the sliders.

[0006] In the above scheme, a drainage trough is provided below the filter tank, and the cross-section of the drainage trough is provided with an inverted cone.

[0007] In the above scheme, a liquid outlet pipe is provided in the middle of the lower part of the drainage trough, and a valve is provided on the liquid outlet pipe.

[0008] In the above scheme, reinforcing plates are provided on both sides below the fixing plate, and the reinforcing plates are fixedly connected to the filter tank below.

[0009] In the above scheme, a control panel is provided on the upper end of the side wall of the filter tank away from the fixed plate.

[0010] Compared with related technologies, this utility model has the following beneficial effects:

[0011] This invention provides a wastewater filtration device. Wastewater enters the filtration tank from above through a pipe. As the wastewater passes through the filter screen, the screen filters out solid impurities. When cleaning the filter screen, a motor drives a gear to rotate. A rack meshing with the gear moves vertically, causing a movable plate to move as well. This movement of the movable plate moves the fixed frame and the filter screen. When the filter screen reaches the top of the filtration tank, workers can directly clean the solid impurities inside. This filtration device has a simple structure, good filtration effect, and easy-to-clean filter screen. While cleaning the filter screen, the device can continuously filter wastewater, effectively improving its working efficiency. Attached Figure Description

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0018] like Figs. 1-3 As shown, this utility model is a sewage filtration device, including four support legs 1. The four support legs 1 are fixedly connected to the upper part of a filter tank 2. A fixing plate 3 is provided on one side of the upper end of the filter tank 2. Columns 4 are provided on both sides above the fixing plate 3. The upper parts of two of the columns 4 are fixedly connected to a top plate 5. A support frame 6 is provided in the middle of the upper part of the top plate 5. A mounting frame 7 is provided on the side of the support frame 6 near the filter tank 2. A motor 8 is fixedly mounted on the mounting frame 7. A gear 9 is provided on the rotating shaft of the motor 8. A movable plate 11 is provided on one side of the mounting frame 7. The movable plate 11 has teeth that mesh with the gear 9. The movable plate 11 is fixedly connected to the fixed frame 12 below. A filter screen frame 13 is provided below the fixed frame 12. The filter screen frame 13 can filter solid impurities in sewage. When the motor 8 is working, the motor 8 drives the gear 9 to rotate. The rack 10 meshing with the gear 9 can move vertically under the drive of the gear 9. Through the transmission of the rack 10, the movable plate 11 also moves. When the movable plate 11 moves, the fixed frame 12 and the filter screen frame 13 also move. When the filter screen frame 13 moves to the upper end of the filter tank 2, the staff can directly clean the solid impurities inside the filter screen frame 13.

[0019] The support frame 6 has two symmetrical sliders 14 on the side near the movable plate 11. The movable plate 11 is provided with a guide rail 15 that matches the sliders 14. The sliders 14 can guide and limit the guide rail 15. Through the cooperation between the sliders 14 and the guide rail 15, the movement stability of the movable plate 11 is effectively improved.

[0020] A drainage trough 16 is provided below the filter tank 2, and the cross section of the drainage trough 16 is provided with an inverted cone.

[0021] A liquid outlet pipe 17 is provided in the middle of the lower part of the drainage tank 16. A valve 18 is provided on the liquid outlet pipe 17. The filtered water can be discharged through the liquid outlet pipe 17 through the conduction of the drainage tank 16. The valve 18 can control the opening and closing of the liquid outlet pipe 17.

[0022] The fixed plate 3 is provided with reinforcing plates 19 on both sides below. The reinforcing plates 19 are fixedly connected to the filter tank 2 below. The setting of the reinforcing plates 19 effectively increases the connection strength between the filter tank 2 and the fixed plate 3, thereby effectively ensuring the overall structural strength of the filtration device.

[0023] The filter tank 2 is equipped with a control panel 20 on the upper side wall away from the fixed plate 3. The working status of the filter device can be controlled through the control panel 20.

[0024] Specifically, wastewater enters the filter tank 2 from above through a pipe. When the wastewater passes through the filter screen 13, the filter screen 13 filters out solid impurities in the wastewater. The filtered wastewater is then discharged from the outlet pipe 17 through the drain trough 16. When cleaning the filter screen 13, the motor 8 drives the gear 9 to rotate. The rack 10, which meshes with the gear 9, moves vertically under the drive of the gear 9. Through the transmission of the rack 10, the movable plate 11 also moves. When the movable plate 11 moves, the fixed frame 12 and the filter screen 13 also move. When the filter screen 13 moves to the upper end of the filter tank 2, the staff can directly clean the solid impurities inside the filter screen 13. The slider 14 can guide and limit the guide rail 15. Through the cooperation between the slider 14 and the guide rail 15, the movement stability of the movable plate 11 is effectively improved.

[0025] 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, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
