Description

Technical Field

[0001] This utility model relates to the technical field of sewage pipeline equipment, specifically a built-in sewage collection and cleaning device for sewage pipelines. Background Technology

[0002] Municipal drainage systems are a crucial component of urban infrastructure, and their stable operation directly impacts residents' quality of life and the city's flood control and drainage capabilities. Currently, municipal road drainage pipes face the following key problems in practical application: frequent pipe blockages and high cleaning costs: outdoor drainage pipes are exposed for extended periods, allowing rainwater or sewage carrying debris such as fallen leaves, silt, and household waste to easily enter the pipes. Over time, this accumulation leads to blockages, requiring significant manpower and resources for pipe dismantling and cleaning, impacting drainage efficiency and increasing municipal maintenance costs; existing filtration structures have design flaws: some drainage devices use flat or single-density filters to intercept debris. On the one hand, unreasonable filter mesh density or support structures occupying the core flow area can reduce the pipe's flow area and increase drainage resistance, exacerbating localized flow velocity reduction and eddy current accumulation, thus increasing the risk of blockage; on the other hand, filter cleaning relies on manual labor, making automatic maintenance impossible, and the accumulation of debris on the filter surface can further obstruct water flow.

[0003] The aforementioned problems make it difficult for existing municipal drainage systems to simultaneously meet the demands of "high-efficiency filtration," "smooth drainage," and "convenient sewage discharge." There is an urgent need for a drainage device that can optimize the flow channel structure and achieve automatic cleaning and active sewage discharge to improve the stability and ease of maintenance of municipal drainage systems. Therefore, we propose a built-in sewage collection and cleaning device for sewage pipes. Utility Model Content

[0004] The purpose of this invention is to provide a built-in sewage collection and cleaning device for sewage pipes to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a built-in sludge collection and cleaning device for a sewage pipe, comprising a pipe body, a fixing ring with a connection hole at the bottom of the pipe body, an inverted hemispherical filter screen with a gradient mesh density inside the pipe body, the hemispherical filter screen being fixed by a three-point suspension bracket, a streamlined hollow motor housing being mounted on the bracket, a rotating shaft being connected to the top of a forward and reverse motor inside the motor housing, a turntable being connected to the side of the rotating shaft, and multiple mounting rods with brushes being bolted to the outside of the turntable, with the brushes adhering to the surface of the filter screen; a sludge collection chamber is formed between the pipe body and the hemispherical filter screen, and a drain pipe and a water inlet pipe are respectively connected to both ends of the pipe body.

[0006] In the above scheme, 4-6 connecting holes are evenly provided on the fixing ring, and the inner diameter of the connecting holes is 10-12mm.

[0007] In the above scheme, 3-4 first support rods are fixedly arranged at equal intervals inside the hemispherical filter screen, and the curvature of the first support rods is consistent with the curvature of the inner wall of the hemispherical filter screen.

[0008] In the above scheme, two second support rods are symmetrically arranged at the bottom of the motor housing. The bottom end of the second support rod is fixedly connected to the fixing ring, and the second support rod is a hollow structure.

[0009] In the above scheme, the main body of the pipeline is provided with ≥2 sewage outlets at intervals on the side, and each sewage outlet is connected in series with a miniature self-priming sewage pump. The distance between the sewage outlets is ≤1.2m and the inner diameter of the opening is ≥60mm.

[0010] In the above scheme, the end of the drain pipe is screwed onto the screw connection part inside the fixing ring, and a nitrile rubber sealing gasket is provided at the connection between the screw connection part and the drain pipe, and the inner diameter of the screw connection part is adapted to the outer diameter of the drain pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This sewage pipe has a built-in sludge collection and cleaning device. Through the combination design of a hemispherical filter screen with a gradient mesh density and a streamlined hollow motor housing, the problem is completely solved: the filter screen inlet pipe side adopts a large aperture to ensure water flow rate, while the outlet pipe side has a small aperture to enhance impurity interception, taking into account both filtration accuracy and flow efficiency; the automatic cleaning mechanism composed of "forward and reverse motor + close-fitting brush" can scrape off the impurities attached to the filter screen in real time, ensuring that the filter screen is unobstructed for a long time; at the same time, the filter screen, mounting rod and other components adopt a detachable design. When replacing the brush or cleaning the filter screen in the future, it is not necessary to disassemble the entire pipe. Only the partial components need to be disassembled to complete the maintenance, which greatly reduces the manual maintenance cost and downtime of the municipal drainage system.

[0016] 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.

[0017] Please see Figure 1-3 This utility model provides a technical solution: a built-in sludge collection and cleaning device for a sewage pipe, including a pipe body 1. The bottom of the pipe body 1 is provided with a fixing ring 11 with a connection hole 12. The pipe body 1 is provided with an inverted hemispherical filter screen 14 with a gradient mesh density. The hemispherical filter screen 14 is fixed by a three-point suspension bracket 15. A streamlined hollow motor housing 16 is installed on the bracket 15. The top of the forward and reverse motor inside the motor housing 16 is connected to a rotating shaft 18. The side of the rotating shaft 18 is connected to a turntable 19. The outside of the turntable 19 is connected by bolts 2 to multiple mounting rods 21 with brushes 22, and the brushes 22 are attached to the surface of the filter screen. A sludge collection chamber is formed between the pipe body 1 and the hemispherical filter screen 14. The two ends of the pipe body 1 are respectively connected to a drain pipe 25 and a water inlet pipe 26.

[0018] In the above scheme, 4-6 connecting holes 12 are evenly provided on the fixing ring 11, and the inner diameter of the connecting hole 12 is 10-12mm.

[0019] In the above scheme, 3-4 first support rods 13 are fixedly arranged at equal intervals inside the hemispherical filter screen 14, and the curvature of the first support rods 13 is consistent with the curvature of the inner wall of the hemispherical filter screen 14.

[0020] In the above scheme, two second support rods 17 are symmetrically arranged at the bottom of the motor housing 16. The bottom end of the second support rod 17 is fixedly connected to the fixing ring 11, and the second support rod 17 is a hollow structure.

[0021] In the above scheme, the main body of the pipeline 1 is provided with ≥2 sewage outlets 23 at intervals on the side, and each sewage outlet 23 is connected in series with a micro self-priming sewage pump. The distance between the sewage outlets is ≤1.2m and the inner diameter of the opening is ≥60mm.

[0022] In the above scheme, the end of the drain pipe 25 is screwed onto the screw connection part 24 inside the fixing ring 11. A nitrile rubber sealing gasket is provided at the connection between the screw connection part 24 and the drain pipe 25, and the inner diameter of the screw connection part 24 is adapted to the outer diameter of the drain pipe 25.

[0023] By setting up a structure including a motor housing 16, a rotating shaft 18, a turntable 19, a mounting rod 21, and a brush 22, the brush 22 is driven by a motor to rotate on the outside of the hemispherical filter screen 14, removing debris from the surface of the filter screen and keeping the filter screen unobstructed. This achieves automatic cleaning of the filtration equipment in the drainage mechanism, ensuring the effectiveness of the filtration mechanism. The cleaned-up impurities can be discharged from the drain outlet.

[0024] Working principle: This type of sewage pipe has a built-in sludge collection and cleaning device. Its working process consists of a filtration stage, an automatic cleaning stage, an active sewage discharge stage, and a stable drainage stage, as detailed below: Filtration stage: Municipal drainage enters the main body of the pipe 1 from the inlet pipe 26. It first flows through the inlet pipe side of the hemispherical filter screen 14 with a gradually changing mesh density, where large particles of debris in the water flow are initially intercepted. The water flow continues to pass through the drain pipe side of the filter screen, where fine impurities are further intercepted. The filtered clean water flows through the gap between the main body of the pipe 1 and the filter screen to the drain pipe 25, and is finally discharged to the municipal drainage branch pipe. The intercepted debris adheres to the surface of the filter screen or falls into the sludge collection chamber for temporary storage.

[0025] Automatic cleaning stage: As debris accumulates, the thickness of impurities in the collection chamber gradually increases; the motor drives the rotating shaft 18 to rotate the turntable 19, and the turntable 19 drives the brush 22 to rotate against the filter screen surface through the mounting rod 21, scraping off the debris attached to the filter screen surface; the scraped debris falls into the collection chamber with the water flow, avoiding filter screen blockage and reduced flow capacity.

[0026] Active sewage discharge stage: The impurity concentration sensing module starts the motor and simultaneously starts the miniature self-priming sewage pump. The sewage pump generates negative pressure, sucking in the impurities and some sewage accumulated in the collection chamber and then discharging them through the sewage outlet 23 to the municipal sewage branch pipe. The sewage discharge process continues until the sensing module detects that the thickness of the impurities in the collection chamber is less than 3mm. The module automatically sends a stop signal, and the motor and sewage pump shut down synchronously, completing one cleaning-sewage cycle.

[0027] Stable drainage stage: After the cleaning-drainage cycle is completed, the filter screen is unblocked, there are no impurities in the collection chamber, and the water can continue to flow through the filter screen and be discharged from the drain pipe 25. If maintenance is required, the mounting rod 21 can be removed to replace the brush 22, or the filter screen can be removed for deep cleaning. There is no need to disassemble the entire pipe, which reduces the difficulty of maintenance.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
