Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and particularly to sewage treatment equipment for municipal water supply and drainage. Background Art

[0002] The sewage treatment of municipal water supply and drainage refers to the treatment of sewage generated in urban life and industrial production through a series of processes and facilities. The purpose is to remove pollutants in the sewage, such as organic matter, nitrogen and phosphorus, suspended solids, etc., so that it meets the national specified discharge standards, thereby protecting the water environment and realizing the recycling of water resources.

[0003] In the sewage treatment process of the municipal water supply and drainage system, adding flocculant to the sewage to achieve the preliminary separation of pollutants is a key step. At present, the common flocculant dosing methods mainly include fixed-point dosing and mobile dosing. Fixed-point dosing equipment is usually fixedly installed at a specific position in the storage tank, and the flocculant is injected into the sewage through a vertical pipe. This method has significant limitations: First, the flocculant can only cover the area around the pipe and is difficult to spread to the entire storage tank, resulting in uneven treatment effects and unable to meet the large-scale sewage treatment requirements; Second, due to the fixed dosing point, it is extremely easy to have the problem of excessive dosing in local areas and insufficient dosing in other areas, which not only causes waste of chemicals but also may affect the normal operation of subsequent sewage treatment processes. Although mobile dosing equipment can improve the coverage problem to a certain extent, the existing technology still has defects. Most mobile devices adopt straight-line reciprocating or random movement paths and continuously dose the flocculant during the movement, resulting in excessive concentration of the flocculant at the starting and ending positions of the movement trajectory and sparse distribution in the middle area, unable to achieve uniform dosing. In addition, some equipment lacks a precise motion control mechanism and is prone to deviation or jamming phenomena, affecting the accuracy and continuity of dosing. At the same time, the dosing methods of existing equipment are single, mostly vertical downward dosing, and the diffusion effect of the flocculant in the sewage is limited, making it difficult to fully exert the flocculation effect of the chemical agent.

[0004] Based on this, a sewage treatment equipment for municipal water supply and drainage is proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide a sewage treatment equipment for municipal water supply and drainage to solve the above problems.

[0006] To achieve the above purpose, the present invention adopts the following technical solutions: The sewage treatment equipment for municipal water supply and drainage includes a dosing cylinder. A sleeve is rotatably connected to the outside of the dosing cylinder. A lifting column is connected to the outside of the sleeve. A translation frame is connected to the lifting column. A chute is provided on the translation frame. The lifting column is slidably connected to the chute. A limiting clip is connected to the lifting column. The limiting clip is slidably connected to the translation frame. A lifting frame is slidably connected to the outside of the translation frame. A transmission member for driving the dosing cylinder to move is connected to the lifting frame; A roller frame is connected to the translation frame. A moving roller is rotatably connected to the roller frame. A collar frame is connected to the upper end of the translation frame. A motor and a storage cylinder are connected to the collar frame. A worm is connected to the output end of the motor. An insertion block is connected to the lower end of the worm. A docking column is connected to the inside of the dosing cylinder through a cross. The docking column and the insertion block fit with each other. A feeding mechanism for intermittently feeding the materials in the storage cylinder into the dosing cylinder is connected to one side of the worm.

[0007] Preferably, a connecting ring is connected to the outside of the dosing cylinder. The sleeve is arranged between the connecting rings.

[0008] Preferably, the transmission member includes a propulsion plate. A deflection rod is connected to the propulsion plate. The deflection rod is rotatably connected to the upper end of the lifting frame. A section steel is arranged below the propulsion plate. A moving tooth is connected to the section steel. The lower end of the propulsion plate abuts against the moving tooth. A stop rod is connected between the lifting frames.

[0009] Preferably, a limiting sleeve is connected to the outside of the translation frame. The lifting frame is slidably connected to the limiting sleeve. The lower end of the lifting frame is rotatably connected to the lifting column.

[0010] Preferably, a discharge port is opened at the lower end of the dosing cylinder. A conical seat is connected to the bottom end inside the dosing cylinder.

[0011] Preferably, the feeding mechanism includes a worm gear. The worm gear is rotatably connected to one side of the worm. The worm gear and the worm mesh with each other. A crank is connected to the outside of the worm gear. A connecting bar is rotatably connected to the crank. The other end of the connecting bar is rotatably connected to the lifting column.

[0012] Preferably, a clamping frame is connected to the outside of the translation frame. A rotating column is connected to the outside of the worm gear. The rotating column is rotatably connected to the clamping frame.

[0013] Preferably, a notch is opened on the conveying pipe. A docking seat is slidably connected to the notch. The docking seat is connected to the sleeve through a separating frame.

[0014] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention are: 1. By adopting the structure of the dosing cylinder and using the method of rotating and dosing the dosing cylinder, the present application can significantly expand the coverage range of the medicament in the sewage. Compared with the traditional fixed-point dosing that can only act on a local area, the flocculant can be evenly diffused throughout the storage tank, avoiding treatment blind spots, greatly improving the sewage treatment efficiency, and effectively meeting the treatment requirements of large-scale municipal water supply and drainage.

[0015] 2. By adopting the structure of the push plate, the present application realizes the alternation of dosing and movement by using the push plate, avoiding the problem that the medicament is overly concentrated at both ends of the movement trajectory and sparse in the middle area of the traditional mobile equipment. This kind of step-by-step dosing operation ensures that the dosing amount of the flocculant at each point is within a reasonable range, achieving uniform dosing, which not only reduces the waste of the medicament but also ensures the consistency of the sewage treatment effect, providing a stable basis for subsequent treatment processes.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0019] Please refer to Figures 1 - 5 , the present invention provides a technical solution: A sewage treatment device for municipal water supply and drainage, including a feeding cylinder 4. A sleeve 3 is rotatably connected to the outside of the feeding cylinder 4. The sleeve 3 is sleeved on the outside of the feeding cylinder 4. A lifting column 8 is connected to the outside of the sleeve 3. The lifting column 8 is vertically connected to the outside of the sleeve 3. A translation frame 5 is connected to the lifting column 8. A chute 22 is provided on the translation frame 5. The lifting column 8 is slidably connected to the chute 22. A limit clamp 26 is connected to the lifting column 8. By providing the limit clamp 26, the left and right deflection of the translation frame 5 is avoided. The limit clamp 26 is slidably connected to the translation frame 5. A lifting frame 7 is slidably connected to the outside of the translation frame 5. The structure of the lifting frame 7 is vertical, and the structure of the translation frame 5 is also vertical. A transmission member for driving the movement of the feeding cylinder 4 is connected to the lifting frame 7; A roller frame 18 is connected to the translation frame 5. A moving roller 19 is rotatably connected to the roller frame 18. Two groups of moving rollers 19 are provided. The structure of the moving roller 19 is in rolling contact with the profiled steel 1. The stability of the movement of the feeding cylinder 4 on the profiled steel 1 is improved through the moving roller 19. A collar frame 28 is connected to the upper end of the translation frame 5. The collar frame 28 is composed of two interconnected rings. A motor 24 and a storage cylinder 9 are connected to the collar frame 28. Through the collar frame 28, the motor 24 and the storage cylinder 9 are fixedly connected. A worm 13 is connected to the output end of the motor 24. A plug 27 is connected to the lower end of the worm 13. A docking column 34 is connected to the feeding cylinder 4 through a cross 31. The docking column 34 is connected to the central position inside the feeding cylinder 4. A groove for docking with the plug 27 is provided on the docking column 34. The docking column 34 and the plug 27 fit each other. A feeding mechanism for driving the intermittent feeding of the material in the storage cylinder 9 into the feeding cylinder 4 is connected to one side of the worm 13.

[0020] Specifically, as Figure 4 and Figure 5 shown, a connecting ring 33 is connected to the outside of the feeding cylinder 4. The sleeve 3 is arranged between the connecting rings 33. By providing the connecting ring 33, the position of the sleeve 3 is limited to prevent the sleeve 3 from being separated from the feeding cylinder 4 up and down.

[0021] Specifically, as Figure 1 and Figure 3As shown in the figure, the transmission part includes a propulsion plate 15. A deflection rod 14 is connected to the propulsion plate 15. The deflection rod 14 is rotatably connected to the upper end of the lifting frame 7. Below the propulsion plate 15, there is a profiled steel 1. The profiled steel 1 structure is erected above the sewage storage tank. By moving the dosing cylinder 4 above the sewage, the flocculant is put into the sewage, thus completing the pretreatment of the sewage. A moving tooth 2 is connected to the profiled steel 1. By setting the moving tooth 2, the effect of the propulsion plate 15 moving to push the dosing cylinder 4 to move is improved, and the contact slip between the propulsion plate 15 and the profiled steel 1 is avoided. The lower end of the propulsion plate 15 abuts against the moving tooth 2. A retaining rod 23 is connected between the lifting frames 7. By setting the retaining rod 23 structure, the limit of the deflection of the propulsion plate 15 is completed. When the equipment moves to one end of the profiled steel 1, the propulsion plate 15 can be flipped and the motor 24 can be controlled to start, enabling the equipment to move in the reverse direction without additional debugging, greatly facilitating the reciprocating movement of the treatment equipment on the profiled steel 1.

[0022] Specifically, as Figure 3 shown, a limit sleeve 20 is connected to the outside of the translation frame 5. The lifting frame 7 is slidably connected to the limit sleeve 20. The lower end of the lifting frame 7 is rotatably connected to the lifting column 8. By setting the limit sleeve 20, the limit of the lifting frame 7 structure is completed. The limit sleeve 20 structure is sleeved on the lifting frame 7.

[0023] Specifically, as Figure 5 shown, a discharge port 21 is opened at the lower end of the dosing cylinder 4. There are multiple discharge ports 21, and the multiple discharge ports 21 are evenly opened at the lower end of the outside of the dosing cylinder 4. Thus, when the dosing cylinder 4 rotates, the flocculant can be thrown out of the dosing cylinder 4. A conical seat 32 is connected to the inner bottom end of the dosing cylinder 4. The setting of the conical seat 32 structure improves the efficiency of the flocculant dosing and avoids the accumulation of the flocculant in the dosing cylinder 4.

[0024] Specifically, as Figure 3 and Figure 4 shown, the feeding mechanism includes a worm gear 16. The worm gear 16 is rotatably connected to one side of the worm 13. The worm gear 16 and the worm 13 are meshed with each other. When the worm 13 rotates, the worm gear 16 can be synchronously driven to rotate. A crank 12 is connected to the outside of the worm gear 16. A connecting bar 6 is rotatably connected to the crank 12. The other end of the connecting bar 6 is rotatably connected to the lifting column 8. A delivery pipe 10 is connected to the lower end of the storage cylinder 9. The lower end of the delivery pipe 10 faces the inside of the dosing cylinder 4. When the lower end of the delivery pipe 10 is opened, the flocculant material can freely fall into the dosing cylinder 4 under the action of gravity.

[0025] Specifically, as Figure 3As shown in the figure, a clamping frame 25 is connected to the outside of the translation frame 5, and a rotating column 17 is connected to the outside of the worm gear 16. The rotating column 17 is rotatably connected to the clamping frame 25. One end of the clamping frame 25 is fixedly connected to the translation frame 5, and the other end of the clamping frame 25 is annular and sleeved on the rotating column 17. The clamping frames 25 on the left and right sides of the worm gear 16 are used to limit its rotation.

[0026] Specifically, as Figure 5 shown in the figure, a notch 29 is opened on the conveying pipe 10, and a docking seat 30 is slidably connected to the notch 29. The docking seat 30 is connected to the sleeve 3 through a separating frame 11. Among them, the structure of the conveying pipe 10 is fixed, while the structure of the docking seat 30 can be lifted up and down. When the docking seat 30 descends, the lower end of the conveying pipe 10 opens, and the material falls. When the docking seat 30 ascends, the lower end of the conveying pipe 10 closes, thus preventing the material from continuing to fall, and thus completing the intermittent feeding operation of the flocculant.

[0027] In summary, for the sewage treatment equipment for municipal water supply and drainage provided in this embodiment, when it is necessary to uniformly treat municipal sewage, it is necessary to put flocculant into the sewage at the initial stage of treatment, so that the originally difficult-to-precipitate fine suspended particles, colloidal substances, etc. in the sewage aggregate to form larger flocs, accelerate their precipitation speed, realize efficient solid-liquid separation, and significantly reduce the turbidity of the sewage.

[0028] Install the corresponding section steel 1 structure on the reservoir for storing sewage. Facing a large-area reservoir, multiple section steels 1 can be set to ensure that the sewage treatment device can cover the entire reservoir. In the initial state, the feeding cylinder 4 is arranged at one end of the section steel 1. At the initial stage of sewage treatment, a sufficient amount of flocculant particles need to be placed in the storage cylinder 9, and then the motor 24 is started. The motor 24 drives the worm 13 to rotate, and when the worm 13 rotates, it can synchronously drive the plug 27 and the worm gear 16 to rotate.

[0029] When the worm gear 16 rotates, it can drive the crank 12 connected to the outside of the worm gear 16 to rotate, thereby driving the connecting bar 6 connected to one end of the crank 12 to move. The connecting bar 6 is used to pull the lifting column 8 to slide in the chute 22, so that the lifting column 8 moves vertically up and down. When the height of the lifting column 8 rises, it can drive the height of the deflecting rod 14 to rise, so that the pushing plate 15 deflects, changing the position where the lower end of the pushing plate 15 abuts against the moving tooth 2. When the height of the lifting column 8 drops, relying on the state where the pushing plate 15 abuts against the moving tooth 2, it can push the lifting frame 7 and the translation frame 5 to move horizontally in the direction away from the lower end of the pushing plate 15.

[0030] During the lifting and lowering of the casing 3, the separation frame 11 can be driven to move up and down. When the separation frame 11 descends, the disc on the docking seat 30 separates from the lower end of the conveying pipe 10. At this time, the opening at the lower end of the conveying pipe 10 is in an open state, and the flocculant placed in the storage cylinder 9 can enter the dosing cylinder 4 along the conveying pipe 10. There are also symmetrically arranged notches 29 on the side wall of the conveying pipe 10, and these notches 29 match the structures on both sides of the docking seat 30. Since the docking seat 30 is in a state of moving up and down, the conveying pipe 10 is in an intermittent opening state, so as to achieve the operation of the storage cylinder 9 intermittently feeding materials into the dosing cylinder 4, thus avoiding a large amount of flocculant from accumulating in the dosing cylinder 4 and affecting the normal feeding of the flocculant in the dosing cylinder 4. Since the flocculant is in the structure of solid small particles, a large amount of accumulated flocculant is extremely likely to cause the problem of blocking the discharge port 21. The setting of the conical seat 32 can also avoid the accumulation of flocculant in the dosing cylinder 4 and improve the discharging efficiency of the flocculant from the discharge port 21.

[0031] When the insertion block 27 rotates, it can drive the docking column 34 to rotate synchronously through the cooperation with the docking column 34. Since the docking column 34 itself will move up and down, during the lifting and lowering process, the docking column 34 always maintains a clamped state with the insertion block 27. By using the rotation of the docking column 34, the dosing cylinder 4 is driven to rotate, and the flocculant in the dosing cylinder 4 can be thrown out by the way of rotational centrifugation, so that the flocculant particles are thrown out in a circular shape from the discharge port 21. Since the rotational feeding is carried out during the lifting and lowering process, the coverage range of the flocculant feeding is greatly improved, thus ensuring that the flocculant can pre-treat the sewage in a large area. By adopting the method of intermittently feeding materials into the dosing cylinder 4, instead of adding a sufficient amount of flocculant in the dosing cylinder 4, the problem of flocculant blocking the discharge port 21 is avoided. The quantitative feeding can also accurately control the feeding amount of the flocculant in the dosing cylinder 4 and improve the uniformity of sewage treatment.

[0032] This equipment can accurately address the pain points of the existing flocculant feeding technology, such as insufficient coverage range, uneven feeding, and easy blockage. Through the innovative design of the steel profile 1 track and rotational feeding, it realizes the full coverage of large-area reservoirs. Its unique intermittent feeding and alternating motion mechanism not only ensures the uniformity of flocculant feeding but also effectively avoids the problem of chemical agent accumulation and blockage. Compared with traditional equipment, this device not only significantly improves the efficiency and quality of sewage treatment but also reduces chemical agent waste and maintenance costs, providing an efficient, intelligent, and economical solution for the field of municipal water supply and drainage sewage treatment, and strongly promoting the innovation and development of sewage treatment technology.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
