Description

Technical Field

[0001] This utility model belongs to the technical field of municipal drainage equipment, and specifically relates to a rainwater and sewage separation municipal pipeline sewage storage tank. Background Technology

[0002] A stormwater and sewage separation system with a sludge storage tank is a type of urban infrastructure designed to separate stormwater and sewage. This system effectively prevents stormwater from mixing with domestic sewage by establishing independent stormwater and sewage pipes, reducing environmental pollution. The sludge storage tank, as a crucial component, is used to temporarily store sewage for treatment before discharge. This design improves sewage treatment efficiency, ensures urban water environment safety, and also facilitates rainwater recycling, promoting sustainable urban development.

[0003] Utility model patent CN217974719U discloses a sludge storage tank for municipal pipelines with separate stormwater and sewage systems. The tank includes a main body, an inlet pipe, and an outlet pipe. A stepped groove is formed on the upper surface of the main body, and a cover plate is installed within the groove. A filter screen is installed on the inner wall of the main body, and a rotating shaft is rotatably connected to the bottom wall of the main body. The shaft passes through the filter screen and is rotatably connected. A blade is fixedly mounted on the shaft, and a drive assembly is installed between the shaft and the cover plate. When floating debris enters the sludge storage tank with sewage, larger debris that could easily clog the outlet pipe is blocked by the filter screen. The operator drives the rotating shaft via the drive assembly, causing the blade to agitate and cut the larger floating debris in the sewage. After being agitated and chopped, the debris is reduced in size and can then pass through the filter screen and be discharged from the outlet pipe, reducing the probability of debris clogging the outlet pipe and thus minimizing the risk of sewage overflow from the sludge storage tank.

[0004] This existing technology still has some problems:

[0005] First, in order to reduce the probability of floating objects clogging the sewage pipe, the device uses a rotating shaft to drive the blades to rotate, cutting the floating objects while stirring. However, this stirring and cutting method is relatively simple, making it difficult to cut all the floating objects into small pieces that can pass through the filter screen, and the cutting efficiency is low.

[0006] Secondly, once floating debris enters the sludge storage tank, it easily adheres to its inner wall, making it difficult to cut off and, over time, causing the inner wall of the sludge storage tank to become difficult to clean. Utility Model Content

[0007] In order to solve the above-mentioned problems in the existing technology, the purpose of this utility model is to provide a rainwater and sewage separation municipal pipeline sewage storage tank.

[0020] As a preferred embodiment of this utility model, the scraper and the rotating shaft are connected by a plurality of damping rods, and each damping rod is fitted with a spring on its outer side, with both ends of the springs fixedly connected to the scraper and the rotating shaft respectively.

[0021] As a preferred embodiment of this utility model, the filter screen is fixedly connected to the lower part of the inner wall of the sludge storage tank body, the filter screen is arranged above the sewage pipe, and the brush plate is fixedly connected to the lower end of the rotating shaft.

[0022] As a preferred embodiment of this utility model, the cover plate has a cavity in the middle, the upper end of the rotating shaft passes through the cavity and is fixedly connected to the gear 2, the front end of the gear 2 is meshed with the gear 3, and the lower front part of the inner wall of the cavity is fixedly connected to the motor that cooperates with the gear 3.

[0023] As a preferred embodiment of this utility model, a controller is provided at the rear upper part of the cover plate, and the controller is electrically connected to the motor.

[0024] As a preferred embodiment of this utility model, a baffle plate rotatably connected to the cover plate is provided above the cavity, and the baffle plate has a plurality of heat dissipation holes.

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0036] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be combined with each other.

[0037] like Figures 1-6 As shown, the rainwater and sewage separation municipal pipeline storage tank of this embodiment mainly includes a storage tank body 1 with an opening at the top, a cover plate 2 set on the upper part of the inner wall of the storage tank body 1, a filter screen 3, a brush plate 4, a stirring device 5, and a scraping structure 10.

[0038] The cover plate 2 and the sludge storage tank body 1 are connected by a locking part (not shown in the figure), and a sealing part (not shown in the figure) is provided at the connection between the cover plate 2 and the sludge storage tank body 1. An L-shaped sludge inlet pipe 13 is fixedly connected to the front upper part of the cover plate 2, and a sludge outlet pipe 14 is fixedly connected to the lower rear end of the sludge storage tank body 1. Both the sludge inlet pipe 13 and the sludge outlet pipe 14 are connected to the interior of the sludge storage tank body 1.

[0039] Then, the stirring device 5 includes a first rotating shaft 6 and several second rotating shafts 7. Rotating blades 8 are fixedly connected to the outer periphery of the first rotating shaft 6, and several cutting blades 9 are fixedly connected to the outer periphery of the second rotating shafts 7. The first rotating shaft 6 is bearing-connected to the lower center of the cover plate 2. Connecting plates 15 are fixedly connected to the upper front, rear, and sides of the first rotating shaft 6. The rotating blades 8 are located below the connecting plates 15. The second rotating shafts 7 are rotatably connected to the lower ends of the front and rear connecting plates 15 on opposite sides. A gear 16 is fixedly connected to the upper part of the second rotating shaft 7. A gear ring 26, meshing with the gear 16, is fixedly connected to the upper part of the inner wall of the sludge storage tank body 1. The gear ring 26 is an internal gear ring. A brush is fixedly connected to the lower end of the brush plate 4, and a filter screen 3 is fixedly connected to the lower part of the inner wall of the sludge storage tank body 1. The filter screen 3 is positioned above the drain pipe 14. The filter screen 3 has a circular mesh structure in cross-section. The brush plate 4 is fixedly connected to the lower end of the rotating shaft 6, and the brush part of the brush plate 4 is movably connected to the upper end of the filter screen 3. The lower ends of the rotating shafts 7 and 17 are both positioned above the filter screen 3. To prevent uncut floating debris from clogging the filter screen 3, the brush plate 4 cleans the floating debris from the surface of the filter screen 3 as it rotates with the rotating shaft 6.

[0040] To drive the stirring device 5, a cavity 20 is formed in the middle of the cover plate 2. The upper end of the rotating shaft 6 passes through the cavity 20 and is fixedly connected to a gear 21. The front end of the gear 21 is meshed with a gear 3 22. A motor 23, which meshes with the gear 3 22, is fixedly connected to the lower front part of the inner wall of the cavity 20. The upper end of the output shaft of the motor 23 is fixedly connected to the lower end of the gear 3 22. A sealing gasket is provided at the connection between the rotating shaft 6 and the inner wall of the cavity 20. The sealing gasket is made of rubber material, which has strong sealing properties, thereby reducing the probability of sewage entering the cavity 20 and damaging the motor 23. A controller 24 is provided at the upper rear part of the cover plate 2. The controller 24 is electrically connected to the motor 23 and is used to control the start and stop of the motor 23. A baffle 25 is rotatably connected to the cover plate 2 above the cavity 20. The baffle 25 can be snapped onto the cover plate 2 to facilitate maintenance of the motor 23 by the staff. The baffle 25 has several heat dissipation holes 12, which provide heat dissipation for the operation of the motor 23 and are conducive to the normal operation of the motor 23.

[0041] When sewage enters the storage tank body 1 through the inlet pipe 13, the controller 24 controls the motor 23 to start. When the motor 23 starts, it drives the gear 3 22 to rotate, which in turn drives the gear 21 meshing with it to rotate. When the rotating shaft 1 6 rotates, it drives the connecting plates 15 at the front and rear to rotate. The rotating shaft 2 7 at the front and rear rotates around the rotating shaft 1 6. The gear 16 on the rotating shaft 2 7 meshes with the gear ring 26. As it rotates with the rotating shaft 2 7, the gear 16 itself also rotates, driving the rotating shaft 2 7 and the cutting blade 9 to rotate. When it revolves around the rotating shaft 1 6, it also rotates on its own axis, resulting in better cutting effect and improved cutting efficiency. Furthermore, when the rotating blade 8 rotates with the rotating shaft 1 6, it can lift the floating objects deposited at the bottom to the upper inner part of the storage tank body 1, so that the floating objects are cut into smaller pieces that can pass through the filter screen 3 more thoroughly.

[0042] Specifically, the scraping structure 10 includes an arc-shaped scraper 11 and several rotating shafts 17. The rotating shafts 17 are fixedly connected to the lower ends of the two connecting plates 15 on opposite sides. The scrapers 11 are respectively arranged on the opposite sides of the rotating shafts 17 on both sides and are symmetrically arranged on both sides. The scrapers 11 and the inner wall of the sludge storage tank body 1 are shaped to match. The opposite ends of the scrapers 11 on both sides slide against the inner wall of the sludge storage tank body 1. The scrapers 11 and the rotating shafts 17 are connected by several damping rods 18. Springs 19 are sleeved on the outer side of each damping rod 18. The two ends of the springs 19 are fixedly connected to the scrapers 11 and the rotating shafts 17 respectively.

[0043] When the rotating shaft 6 rotates, the rotating shafts 17 on both sides are driven to rotate around the rotating shaft 6 through the connecting plates 15 on both sides. Under the elastic force of the damping rod 18 and the spring 19, the scraper blades 11 on both sides are always in contact with the inner wall of the sludge storage tank body 1. When the scraper blades 11 rotate, they scrape off the floating objects attached to the inner wall of the sludge storage tank body 1 to prevent the situation from being difficult to clean in the long term. After being scraped off, they are cut into small pieces by the cutting blades 9.

[0044] It should be noted that all electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device such as a computer. The specific implementation of this disclosure omits detailed descriptions of known functions and components. To ensure device compatibility, the operating methods used are consistent with the parameters of commercially available instruments.

[0045] This utility model is not limited to the above-mentioned optional embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in its shape or structure, any technical solution that falls within the scope of the claims of this utility model shall be protected by this utility model.
