Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an interception device for wastewater treatment. Background Technology
[0002] Wastewater interception devices are key equipment in the wastewater treatment process, used to block larger solid debris from entering subsequent treatment units. They typically consist of screens, filters, or similar structures, using different pore sizes and construction to effectively intercept impurities of varying sizes.
[0003] Wastewater treatment interception devices utilize the principle of physical barrier. Through components such as grilles and filters, they intercept solid impurities in wastewater with pores smaller than the size of the impurities. This allows wastewater to pass through while impurities are trapped. Based on the principles of gravity and hydrodynamics, under the action of gravity, impurities with higher density settle, while changes in water flow velocity cause impurities to collide with the surface of the interception device and be intercepted.
[0004] In existing technologies, some wastewater treatment interception devices suffer from numerous drawbacks due to traditional wastewater treatment filter cleaning methods. Some rely on manual cleaning, which not only consumes significant manpower and time but also suffers from low cleaning efficiency, failing to meet the continuous operation requirements of wastewater treatment equipment. This results in the filter remaining clogged for extended periods, hindering wastewater flow and severely impacting treatment efficiency. Therefore, this paper proposes a wastewater treatment interception device to address these issues. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an interception device for sewage treatment, which aims to improve the problem of long-term clogging of filter screens in the prior art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A wastewater treatment interception device includes a carrier block, with fixed blocks fixedly connected to both the left and right sides of the inner wall of the carrier block. A slider is slidably connected inside the fixed block. Two rotating wheels are rotatably connected to the adjacent sides of the two sliders respectively. A connecting rod is fixedly connected to the rear side of the slider. A limit block is fixedly connected to the inner wall of the carrier block. Two rotating rods are rotatably connected to the rear side of the connecting rod. A cleaning plate is rotatably connected to the rear side of the two rotating rods. A spring is sleeved on the outside of the connecting rod. A fixing groove is opened inside the carrier block. A portable component for cleaning the solid waste pool is fixedly connected to the rear inner wall of the fixing groove.
[0008] As a further description of the above technical solution:
[0009] The portable component includes a motor, a gear is fixedly connected to the drive end of the motor, a movable plate is slidably connected inside the carrier block, a tooth is fixedly connected to the right side of the movable plate, a connecting rod is rotatably connected to the top of the movable plate, and a baffle is rotatably connected to the top of the connecting rod.

[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, water flow acts on the rotating wheel, causing it to rotate under pressure. The rotating wheel drives the slider to slide within the fixed block, and the connecting rod on the rear side of the slider moves accordingly, thereby driving the rotating rod on the rear side to move synchronously. The movement of the rotating rod causes the cleaning plate connected to it to move. Under the guidance and limitation of the moving block, the cleaning plate performs reciprocating cleaning of the filter screen, thereby realizing automatic reciprocating cleaning of the filter screen, efficiently removing impurities from the filter screen, ensuring the filtration effect of the filter screen, and the spring reset design allows the cleaning plate to automatically reset after the water flow stops. The structure is simple and reliable, facilitating the continuous and stable operation of the equipment.
[0024] 2. In this utility model, the motor drives the gear to rotate, which in turn drives the moving plate to move up and down inside the carrier block. The moving plate drives the connecting rod to move synchronously, which in turn drives the top rotating baffle to slide. This achieves precise control of the baffle to block the water inlet, providing a safe and convenient operating environment for operators to enter the carrier block to clean solid impurities in the placement tank, and greatly reducing the difficulty of cleaning.

Detailed Implementation
[0033] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] Reference Figure 1 , Figure 3 and Figure 4The present invention provides an embodiment of an interception device for sewage treatment, comprising a carrier block 1, which provides fixation and support for the internal device. Fixing blocks 2 are fixedly connected to the left and right sides of the inner wall of the carrier block 1, providing guidance and limiting for the slider 3. A slider 3 is slidably connected inside the fixing block 2, and the slider 3 is rotated by receiving force from rotating wheels 4. Two rotating wheels 4 are rotatably connected to the adjacent sides of the two sliders 3, and the rotating wheels 4 rotate under the pressure of water flow, causing the sliders 3 to slide. A connecting rod 5 is fixedly connected to the rear side of the slider 3, and the connecting rod 5 moves under the force from the slider 3. A limiting block 6 is fixedly connected to the inner wall of the carrier block 1, providing guidance and limiting for the connecting rod 5.
[0035] Two rotating rods 7 are rotatably connected to the rear side of the connecting rod 5. The rotating rods 7 receive the force from the connecting rod 5 and move synchronously. The cleaning plate 8 is rotatably connected to the rear side of the two rotating rods 7. The cleaning plate 8 receives the force from the rotating rods 7 and moves to achieve reciprocating cleaning. A spring 9 is sleeved on the outside of the connecting rod 5. The spring 9 has an elastic function and can drive the slider 3 to reset through its own elasticity after the slider 3 is subjected to force. A fixing groove 10 is opened inside the carrier block 1. The fixing groove 10 provides installation space for the cleaning component. A portable component for cleaning the solid pool is fixedly connected to the rear inner wall of the fixing groove 10.
[0036] Reference Figure 2 and Figure 5 The portable component includes a motor 11, which is the power source for the portable component. A gear 12 is fixedly connected to the drive end of the motor 11. The gear 12 receives force from the motor 11 and rotates. The gear 12 meshes with a tooth 14, which drives the moving plate 13 to move. The moving plate 13 is slidably connected inside the carrier block 1. The moving plate 13 receives force from the tooth 14 and moves up and down. The right side of the moving plate 13 is fixedly connected with a tooth 14. Similarly, the gear 12 meshes with the tooth 14, which drives the moving plate 13 to move. A connecting rod 15 is rotatably connected to the top of the moving plate 13. The connecting rod 15 receives force from the moving plate 13 and moves, which in turn drives the baffle 16 to slide. The top of the connecting rod 15 is rotatably connected to the baffle 16. The baffle 16 can block the water inlet when the moving plate 13 rises.
[0037] Reference Figure 3 and Figure 6The carrier block 1 has multiple grooves 19 inside, which guide and limit the movement block 20. The movement block 20 is slidably connected inside the grooves 19, and the movement block 20 guides and limits the cleaning plate 8. The rear side of spring 19 is fixedly connected to the rear inner wall of fixing block 2, which provides fixation and support for spring 19. The front side of spring 19 is fixedly connected to the rear side of slider 3, which provides fixation and support for spring 19. The top of one of the movement blocks 20 is fixedly connected to spring 21, which has an elastic function and can push the movement block 20 and thus push the cleaning plate 8 to reset after the force on the movement block 20 ends. A filter screen 22 is slidably connected inside the carrier block 1 to intercept and fix impurities.
[0038] Reference Figures 1 to 3 The carrier block 1 has an inlet groove 17 inside, which allows operators to enter the carrier block 1 to clean and fix the pool. The carrier block 1 also has a placement groove 18 inside, which is used to settle and fix impurities. The connecting rod 5 is externally slidably connected to the inside of the fixing block 2. The fixing block 2 provides guidance and limitation for the connecting rod 5. The connecting rod 5 is externally slidably connected to the inside of the limiting block 6. The limiting block 6 provides guidance and limitation for the connecting rod 5. The rear side of the motor 11 is fixedly connected to the rear inner wall of the fixing groove 10. The fixing groove 10 provides fixation and support for the motor 11.
[0039] Working principle: When the filter screen 22 needs to be cleaned, the water flow acts on the rotating wheel 4, causing it to rotate under pressure. The rotating wheel 4 drives the slider 3 to slide within the fixed block 2. The connecting rod 5 on the rear side of the slider 3 moves accordingly, which in turn drives the rotating rod 7 on the rear side to move synchronously. The movement of the rotating rod 7 causes the cleaning plate 8, which is rotatably connected to it, to move. Under the guidance and limitation of the moving block 20, the cleaning plate 8 performs reciprocating motion to clean the filter screen 22. When the water pressure disappears, the slider 3 is no longer under force. The spring 9, which is sleeved on the outside of the connecting rod 5, exerts its elasticity, causing the slider 3 to reset, thereby causing the cleaning plate 8 to reset for the next cleaning.
[0040] When it is necessary to clean the solid impurities inside the placement tank 18, the motor 11 drives the gear 12 to rotate. The gear 12 meshes with the toothed 14, which drives the moving plate 13 to move up and down inside the carrier block 1. The moving plate 13 drives the connecting rod 15 to move synchronously, which in turn drives the top rotating baffle 16 to slide. When the moving plate 13 rises, the baffle 16 blocks the water inlet, making it convenient for the operator to enter the carrier block 1 through the inlet tank 17 to clean the fixed impurities settled in the placement tank 18, thus realizing convenient cleaning of the solid pool.
[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
