Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an interception bar for wastewater treatment ponds. Background Technology

[0002] After treatment, the water quality is significantly reduced from its original polluted state through repeated filtration and elimination, making the water usable again. It can also improve the ecological environment, enhance the city's image, and promote economic development. If sewage is not treated, it will inevitably be discharged into rivers, which will not only pollute the environment but also have an adverse impact on the quality of drinking water for people.

[0003] During wastewater treatment, a large amount of domestic waste is present in the wastewater, which can affect the operation of subsequent wastewater treatment equipment and easily clog wastewater discharge pipes. Therefore, a wastewater treatment interception screen is needed to intercept the waste in the wastewater during treatment. Existing wastewater treatment interception screens usually adopt a simple screen design, and their inlet side will become clogged as waste accumulates, making it impossible to clear the clogged waste. This will lead to a decrease in wastewater treatment efficiency. At the same time, after a long period of time, the simple screen will become insufficient in pressure due to the accumulation of waste, resulting in damage to the simple screen and affecting the wastewater treatment efficiency.

[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4As shown, a wastewater treatment interception screen includes a wastewater tank body 1, which stores wastewater. A water passage 2 is located on one side of the wastewater tank body 1, facilitating the introduction of wastewater into the wastewater tank body 1. A support 3 is fixed to the top of the water passage 2. Since the driving structure is located on the top of the support 3, the support 3 can be easily supported by the driving structure. A toothed plate 4 slides on the inner wall of the support 3. An interception screen body 5 is inserted into the inner wall of the water passage 2, and the top of the interception screen body 5 is fixedly connected to the bottom of the toothed plate 4. 4. The toothed plate 4 slides on the inner wall of the bracket 3, and the bottom of the toothed plate 4 is fixedly connected to the top of the intercepting grid body 5. Therefore, when the drive structure drives the toothed plate 4 to rise and fall, the toothed plate 4 can drive the intercepting grid body 5 to rise and fall. It should be noted that after long-term use, due to the accumulation of garbage in the sewage, the grid bars in the intercepting grid body 5 may be damaged due to corrosion, wear, or impact from large debris. Lifting the intercepting grid body 5 above the water surface allows operators to easily repair or replace the damaged grid bars without draining the water or entering the sewage tank for underwater operations, reducing maintenance difficulty and safety risks. At the same time, during sewage treatment, some large debris may become entangled on the intercepting grid body 5. If it cannot be cleaned by the cleaning structure, it will cause blockage of the intercepting grid body 5, affecting its water flow capacity. By lifting the intercepting grid body 5, it can be lifted out of the water surface, allowing operators to visually observe the blocked debris and use tools to remove it, restoring the normal filtration function of the intercepting grid body 5. The limiting plate 6 is fixed to one side of the intercepting grid body 5. A vertically arranged pull rod 7 is slidably connected to the wall, and a horizontally arranged brush plate 8 is fixed at the bottom end of the pull rod 7. Since the pull rod 7 is slidably connected to the inner wall of the limiting plate 6 fixed on one side of the intercepting grid body 5, and since the brush plate 8 is fixed at the bottom of the pull rod 7, the brush plate 8 can be moved up and down when the pull rod 7 is pulled up and down. The brush plate 8 can clean the garbage accumulated on the surface of the intercepting grid body 5. A support mechanism 9 is provided on the side of the intercepting grid body 5 near the sewage tank body 1. The support mechanism 9 can support the intercepting grid body 5 through its internal structure.

[0024] The support mechanism 9 includes two sets of support plates 91 fixed to one side of the intercepting grid body 5. Three sets of connecting seats 92 are provided on one side of the support plate 91. A support rod 93 is rotatably connected to the inner wall of the connecting seat 92. A pin 94 is rotatably connected to the end of the support rod 93 away from the connecting seat 92, and the end of the pin 94 away from the support rod 93 is slidably connected to the inner wall of the water passage 2. Since the support plate 91 is fixed to one side of the intercepting grid body 5, and since the support rod 93 is installed on one side of the support plate 91 through the connecting seat 92, and since the pin 94 at one end of the support rod 93 can be inserted into the inner wall of the water passage 2, the support rod 93 can support the intercepting grid body 5, thereby improving the pressure resistance of the intercepting grid body 5.

[0025] A housing 10 is fixed to the inner wall of the bracket 3, and a fixing frame 11 is installed on the top of the bracket 3. A vertically mounted motor 12 is installed on the inner wall of the fixing frame 11. A worm gear 13 is fixed to the output end of the motor 12, and the end of the worm gear 13 away from the motor 12 is rotatably connected to the inner wall of the housing 10. A worm wheel 14 is threaded to the outer side of the worm gear 13. A horizontally arranged transmission rod 15 is fixed at the axis of the worm wheel 14, and both ends of the transmission rod 15 are rotatably connected to the inner wall of the bracket 3. Two sets of gears 16 are fixed to both ends of the transmission rod 15, and the gears 16 mesh with the gear plate 4. When it is necessary to remove the interception grille body 5, the motor 10 installed on the top of the bracket 3 is started first. 2. The motor 12 can drive the worm 13 fixed at its output end to rotate. The worm 13 drives the worm wheel 14 to rotate. The worm wheel 14 can drive the transmission rod 15 fixed at its shaft to rotate. The transmission rod 15 can drive the gears 16 fixed at both ends to rotate in the same direction. Since the gears 16 are meshed with the toothed plate 4, the gears 16 can drive the toothed plate 4 to move up and down. The toothed plate 4 drives the intercepting grid body 5 fixed at its bottom to rise and fall. Since the bottom end of the worm 13 is rotatably connected to the inner wall of the outer shell 10, and the worm wheel 14 is located inside the outer shell 10, the outer shell 10 can protect the worm 13 and the worm wheel 14.

[0026] The inner wall of the bracket 3 is provided with a limiting groove 17, and both ends of the intercepting grid body 5 are fixed with limiting blocks 18. The outer side of the limiting block 18 is slidably connected to the inner wall of the limiting groove 17. Since the limiting blocks 18 fixed at both ends of the intercepting grid body 5 are slidably connected to the inner wall of the limiting groove 17 provided in the inner wall of the bracket 3, the intercepting grid body 5 can be limited by the cooperation of the limiting groove 17 and the limiting block 18 during the movement of the intercepting grid body 5.

[0027] When sewage interception is required, the motor 12 installed on the top of the support 3 is first started. The motor 12 drives the worm 13 fixed at its output end to rotate. The worm 13 drives the worm wheel 14 to rotate. The worm wheel 14 drives the transmission rod 15 fixed at its shaft to rotate. The transmission rod 15 drives the gears 16 fixed at both ends to rotate in the same direction. Since the bottom end of the worm 13 is rotatably connected to the inner wall of the outer casing 10, and the worm wheel 14 is located inside the outer casing 10, the outer casing 10 can protect the worm 13 and the worm wheel 14. At the same time, since the gear 16 is meshed with the toothed plate 4, the gear 16 can drive the toothed plate 4 to move up and down. Since the toothed plate 4 slides on the inner wall of the support 3, and the bottom of the toothed plate 4 is fixedly connected to the top of the interception grid body 5, the toothed plate 4 can drive the interception... When the grille body 5 is raised and lowered and moved into the water passage 2, the pin 94 at one end of the support rod 93 is inserted into the inner wall of the water passage 2. Since the support plate 91 is fixed to one side of the grille body 5, and the support rod 93 is installed on one side of the support plate 91 through the connecting seat 92, the support rod 93 can support the grille body 5, thereby improving the pressure resistance of the grille body 5. When it is necessary to clean the grille body 5, the pull rod 7 is pulled up and down. Since the pull rod 7 is slidably connected to the inner wall of the limiting plate 6 fixed to one side of the grille body 5, and since the brush plate 8 is fixed to the bottom of the pull rod 7, the brush plate 8 can be moved up and down when the pull rod 7 is pulled up and down. The brush plate 8 can clean the garbage accumulated on the surface of the grille body 5.
