Description

Technical Field

[0001] This utility model relates to the field of domestic sewage treatment technology, and in particular to an adjustable interception bar for domestic sewage treatment. Background Technology

[0002] Domestic sewage treatment is a general term for sewage discharged into urban sewage systems. In combined sewer systems, it also includes industrial wastewater and intercepted rainwater. Urban sewage mainly includes domestic sewage and industrial wastewater, which are collected by the urban drainage network and transported to sewage treatment plants for treatment. During treatment, interception screens are used to intercept larger suspended and floating solids in the sewage.

[0003] For example, application number CN217119561U discloses "an adjustable screen for sewage treatment" and specifically discloses that: the mounting box has connecting buckets symmetrically fixed at both ends; the mounting box has supporting feet welded to the bottom; a mounting frame is vertically inserted into the middle of the upper surface of the mounting box; the mounting frame is equidistantly connected to screen plates in the horizontal direction; a drive pulley is fixedly welded to the top shaft of the screen plate; a control box is fixedly connected to the top of the mounting frame; a common pulley is rotatably connected to the edge of the inner cavity of the control box; an adjustment mechanism for adjusting the rotation angle of multiple screen plates is provided at the position of the common pulley; a common belt is sleeved on the outer wall of the common pulley and multiple drive pulleys; and a top cover is bolted to the top of the control box. However, in the above technology, the screen is adjusted by using gear and rack transmission, but gears and racks do not have self-locking properties during transmission. Therefore, the screen is easily rotated by water flow impact during use, reducing its practicality. Therefore, this utility model proposes an adjustable interception screen for domestic sewage treatment to solve the above problems. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes an adjustable interception screen for domestic sewage treatment. This solves the problem that existing technologies use gears and racks to adjust the screen, but gears and racks lack self-locking properties during transmission. As a result, the screen is easily rotated by water flow during use, reducing its practicality.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: an adjustable interception bar for domestic sewage treatment, including a frame, a horizontal plate installed at the front end of the frame, a partition installed inside the frame, a rotating shaft installed between the two partitions on the inner side of the frame, the top end of the rotating shaft extending to the top end of the frame, a top cavity installed at the top end of the frame, an adjustment mechanism provided inside the top cavity, and a first bar plate, a second bar plate and a third bar plate symmetrically installed at equal intervals on the outer side wall of the rotating shaft;

[0006] The adjusting mechanism includes a transmission gear ring, a transmission rod, a first transmission tooth, and a transmission structure. The transmission gear ring is respectively installed on the outer side wall of the rotating shaft. The transmission gear ring is located at the top of the frame. The transmission rod is installed at the top of the frame. One end of the transmission rod is equipped with a first transmission tooth, which meshes with the plurality of transmission gear rings.

[0007] A further improvement is made in that: the transmission structure includes a second transmission tooth, a mounting bracket, a servo motor, a worm gear, a worm wheel, a drive gear, and a limiting structure. The second transmission tooth is mounted on the other end of the transmission rod. The mounting bracket is mounted on the top of the frame. A servo motor is mounted on one side of the mounting bracket. A worm gear is mounted on the upper inner side of the mounting bracket. The output end of the servo motor is connected to one end of the worm gear. A worm wheel meshes with one end of the worm gear. A drive gear is coaxially mounted on the bottom end of the worm wheel. One side of the drive gear meshes with one side of the second transmission tooth.

[0008] A further improvement is that the limiting structure includes a limiting rail and a limiting block. The limiting rail is installed at the middle position of the top of the frame, and a limiting block is provided inside the limiting rail. One end of the limiting block is connected to one end of the transmission rod.

[0009] A further improvement is that the cross-section of the limiting rail is larger than the cross-section of the limiting block, and the limiting rail and the limiting block form a sliding structure.

[0010] A further improvement is that: the front end of the frame of the horizontal plate is provided with multiple partitions, and multiple partitions are provided inside the frame, with the multiple horizontal plates and partitions being distributed at equal intervals.

[0011] A further improvement is that the cross-section of the first grid plate is larger than the cross-section of the second grid plate, and the cross-section of the second grid plate is larger than the cross-section of the third grid plate.

[0012] The beneficial effects of this utility model are as follows: By setting an adjustment mechanism inside the top cavity, the interaction between the transmission gear ring, transmission rod, first transmission gear, second transmission gear, mounting bracket, servo motor, worm gear, worm wheel, drive gear, limit rail, and limit block of the adjustment mechanism can drive the rotating shaft to rotate, thereby driving the first, second, and third grid plates to rotate. According to the different floating objects in the sewage, the first, second, and third grid plates can be adjusted to appropriate positions to change the filter spacing of the grid. At the same time, the self-locking design of the worm gear and worm wheel makes the grid more stable during use and less susceptible to rotation due to water flow impact, thus greatly improving the practicality of the grid during use.

[0018] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0019] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes an adjustable interception bar for domestic sewage treatment, including a frame 1. A horizontal plate 2 is installed at the front end of the frame 1, and a partition 3 is installed inside the frame 1. A rotating shaft 5 is installed between the two partitions 3 on the inner side of the frame 1. The top end of the rotating shaft 5 extends to the top end of the frame 1. A top cavity 4 is installed at the top end of the frame 1. An adjustment mechanism is provided inside the top cavity 4. A first bar plate 6, a second bar plate 7, and a third bar plate 8 are symmetrically installed at equal intervals on the outer side wall of the rotating shaft 5.

[0020] The adjustment mechanism includes a transmission gear ring 9, a transmission rod 10, a first transmission tooth 11, and a transmission structure. The transmission gear ring 9 is respectively installed on the outer side wall of the rotating shaft 5. The transmission gear ring 9 is located at the top of the frame 1. The transmission rod 10 is installed at the top of the frame 1. One end of the transmission rod 10 is equipped with the first transmission tooth 11, which meshes with the multiple transmission gear rings 9. The transmission structure includes a second transmission tooth 12, a mounting bracket 13, a servo motor 14, a worm gear 15, a worm wheel 16, and a drive gear 1. 7. A limiting structure is provided. The second transmission tooth 12 is installed at the other end of the transmission rod 10. The mounting bracket 13 is installed at the top of the frame 1. A servo motor 14 is installed on one side of the mounting bracket 13. A worm gear 15 is installed on the upper inner side of the mounting bracket 13. The output end of the servo motor 14 is connected to one end of the worm gear 15. A worm wheel 16 meshes with one end of the worm gear 15. A drive gear 17 is coaxially installed at the bottom end of the worm wheel 16. One side of the drive gear 17 meshes with one side of the second transmission tooth 12. In use, the servo motor 14 is activated. Motor 14 drives worm 15 to rotate. Since worm 15 meshes with worm wheel 16, and worm wheel 16 is coaxially mounted with drive gear 17, worm wheel 16 drives drive gear 17 to rotate. Since drive gear 17 meshes with second transmission teeth 12, under the limitation of limit rail 18 and limit block 19, drive gear 17 drives transmission rod 10 to move. Since first transmission teeth 11 meshes with multiple transmission gear rings 9, first transmission teeth 11 drive transmission gear rings 9 to rotate. This drives the rotating shaft 5 to move, which in turn drives the first grid plate 6, the second grid plate 7, and the third grid plate 8 to rotate and adjust them to appropriate positions to intercept and treat floating objects in the sewage. Depending on the type of floating objects in the sewage, the first grid plate 6, the second grid plate 7, and the third grid plate 8 are adjusted to appropriate positions to change the filter spacing of the grid. At the same time, the self-locking design of the worm gear 15 and the worm wheel 16 makes the grid more stable during use and less susceptible to rotation due to water flow impact, thereby greatly improving the practicality of the grid during use.

[0021] The limiting structure includes a limiting rail 18 and a limiting block 19. The limiting rail 18 is installed at the middle position of the top of the frame 1. The limiting rail 18 is provided with a limiting block 19 inside. One end of the limiting block 19 is connected to one end of the transmission rod 10. The cross-section of the limiting rail 18 is larger than the cross-section of the limiting block 19. The limiting rail 18 and the limiting block 19 form a sliding structure. In use, the mutual cooperation between the limiting rail 18 and the limiting block 19 can limit the movement of the transmission rod 10, making the transmission rod 10 more stable when moving.

[0022] The front end of the frame 1 of the horizontal plate 2 is provided with multiple partitions 3, and multiple partitions 3 are provided inside the frame 1. The multiple horizontal plates 2 and partitions 3 are distributed at equal intervals. When in use, they can intercept and treat floating objects in sewage.

[0023] The cross-section of the first grid plate 6 is larger than that of the second grid plate 7, and the cross-section of the second grid plate 7 is larger than that of the third grid plate 8. In use, the positions of the first grid plate 6, the second grid plate 7 and the third grid plate 8 are adjusted according to the actual situation to change the filter spacing of the grid.

[0024] Working principle: The operator installs the screen in a suitable position and uses the horizontal plate 2, partition plate 3, rotating shaft 5, first screen plate 6, and second screen plate 7 to intercept floating objects in the sewage. When it is necessary to change the interception spacing of the screen, the operator starts the servo motor 14 to drive the worm gear 15 to rotate. Since the worm gear 15 and worm wheel 16 are meshed with each other, and the worm wheel 16 and the drive gear 17 are coaxially installed, the worm wheel 16 drives the drive gear 17 to rotate. Since the drive gear 17 and the second transmission tooth 12 are meshed with each other, under the limit of the limit rail 18 and the limit block 19, the drive gear 17 drives the transmission rod 10 to move. Since the first transmission tooth 11 is meshed with multiple transmission tooth rings 9, the first transmission tooth 11 drives the transmission tooth rings 9 to rotate, which in turn drives the rotating shaft 5 to move. The rotating shaft 5 drives the first screen plate 6, the second screen plate 7, and the third screen plate 8 to rotate and adjust them to the appropriate position to intercept floating objects in the sewage.
