Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, and more specifically to a sedimentation treatment device for wastewater treatment. Background Technology
[0002] In the wastewater treatment process, sedimentation is a crucial step, a fact widely recognized in existing technologies. Its main function is to purify wastewater by removing suspended solids and impurities. This is a fundamental and critical step in the wastewater treatment process. However, unless it is a newly built wastewater sedimentation device or facility with a well-designed and structurally sound structure, which is relatively complete in function and can meet basic wastewater treatment needs, there is still room for further improvement in existing wastewater treatment sedimentation equipment and facilities.
[0003] Specifically, after wastewater undergoes sedimentation, some of the lower water layer may mix with the sediment at the bottom, resulting in a higher concentration of suspended solids in the extracted water, thus affecting water cleanliness. While some existing technologies offer automatic cleaning capabilities, these facilities are structurally complex and have relatively high operating costs, making them potentially unsuitable for typical wastewater treatment plants. Traditional wastewater treatment facilities often require additional time and manpower for manual separation and cleaning of sediment, which undoubtedly reduces overall wastewater treatment efficiency and hinders the smooth progress of the process. Furthermore, if the stains adhering to the inner walls of the sedimentation tank cannot be effectively removed after multiple treatments, the treated water may fail to meet standards, further impacting the effectiveness of subsequent wastewater treatment. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a sedimentation treatment device for sewage treatment to solve the problems existing in the background art.

The cleaning component is installed on one side of the sedimentation component, the separation component is installed on the other side of the sedimentation component, the drainage component is located on top of the separation component, and one side of the drainage component is connected to one side of the sedimentation component. The wall scraping component is installed inside the sedimentation component. The wall scraping component includes a fixed body, a wall scraping motor, a fixed column, and scraper rods. The fixed body is fixedly installed on the top of the inner cavity of the sedimentation tank. The wall scraping motor is nested inside the fixed body, and the output shaft of the wall scraping motor is fixedly sleeved to the fixed column through a coupling. The scraper rods are symmetrically installed on both sides of the fixed column.

[0017] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The sedimentation treatment device for sewage treatment involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0018] Reference Figure 1-3 As shown, this utility model provides a sedimentation treatment device for sewage treatment, including a sedimentation component 1, a cleaning component 2, a separation component 3, a drainage component 4, and a wall scraping component 5. The cleaning component 2 is installed on one side of the sedimentation component 1, the separation component 3 is installed on the other side of the sedimentation component 1, the drainage component 4 is disposed on the top of the separation component 3, and one side of the drainage component 4 is connected to one side of the sedimentation component 1. The wall scraping component 5 is installed inside the sedimentation component 1.
[0019] The sedimentation assembly 1 includes a sedimentation tank 101, support legs 102 and an inlet 103. The support legs 102 are evenly installed at the bottom of the sedimentation tank 101, the cleaning assembly 2 and the separation assembly 3, and the inlet 103 is fixedly installed at the top of the sedimentation tank 101.
[0020] The cleaning assembly 2 consists of a first housing 201, a cleaning motor 202, a spiral push rod 203, a transmission rod 204, and a sludge storage container 205. The first housing 201 is fixedly installed on one side of the sedimentation tank 101, while the cleaning motor 202 is embedded inside the first housing 201 and securely connected to the output shaft of the spiral push rod 203 via a coupling. The transmission rod 204 is movably sleeved on the outer side of the spiral push rod 203, and one end of the transmission rod 204 is fixedly connected to the sludge storage container 205. This design facilitates the starting of the cleaning motor 202, whose output shaft drives the transmission shaft to rotate, thereby causing the spiral push rod 203 to rotate. The spiral push rod 203 pushes the transmission rod 204 and the sludge storage container 205 into the separation assembly 3, transporting the sludge deposited at the bottom of the sedimentation tank 101 into the separation assembly 3 for discharge. This process improves sludge removal efficiency while reducing the physical exertion of manual cleaning.
[0021] The separation assembly 3 comprises a second housing 301, a chute 302, a sludge removal port 303, a separation motor 304, a gear 305, a connecting plate 306, a rack 307, and a separation plate 308. The second housing 301 is fixed to one side of the sedimentation tank 101 and has the chute 302 inside. The sludge removal port 303 is located at the bottom of the second housing 301. The separation motor 304 is embedded inside the second housing 301, and its output shaft is fixedly connected to the gear 305 via a coupling. The connecting plate 306 is movably sleeved inside the second housing 301, and a rack 307 is fixedly installed on one side of it, with the gear 305 meshing with the rack 307. The separation plate 308 is fixedly connected to one side of the connecting plate 306 and can be movably engaged inside the sedimentation tank 101.
[0022] After the separation motor 304 is started by the wastewater treatment worker, the output shaft of the separation component 3 constituted by the above structure drives the transmission shaft to rotate. The transmission shaft then drives the gear 305 to rotate. The rotation of the gear 305 drives the meshing rack 307 to move, so that the connecting plate 306, rack 307 and separation plate 308 move inside the sedimentation tank 101 and the second housing 301, thereby achieving effective separation of the settled water and sludge. Moreover, the above structure does not require too many sensing components or transmission components. Under the premise of ensuring minimum transmission accuracy, the requirement for the number of transmission gear teeth is low. No transmission components such as chains or conveyor belts are used, so the manufacturing cost of the equipment of this utility model can be well controlled.
[0023] The drainage assembly 4 consists of a connecting pipe 401, a valve 402, a water pump 403, and an outlet pipe 404. The connecting pipe 401 is fixed to one side of the sedimentation tank 101, and the valve 402 is installed externally on its exterior. The water pump 403 is fixed to one side of the connecting pipe 401 and connected to the outlet pipe 404. This design facilitates starting the water pump 403 after opening the valve 402. The water pump 403 extracts the settled water from the sedimentation tank 101 through the connecting pipe 401 and transports it to other devices for further treatment through the outlet pipe 404. In practical work, when wastewater treatment workers need to discharge the settled water, they simply open the valve 402 and then start the water pump 403. The powerful suction of the water pump 403 acts rapidly inside the sedimentation tank 101 through the connecting pipe 401, extracting the relatively clear water that has undergone sedimentation treatment. The water is then transported along the outlet pipe 404 to a designated downstream treatment unit for more thorough purification. The entire drainage process is both fast and stable, effectively preventing the water from stagnating in the sedimentation tank 101 for an extended period, thereby reducing the risk of the water being contaminated again.
[0024] The wall scraping assembly 5 consists of a fixed body 501, a wall scraping motor 502, a fixed column 503, and a scraper 504. The fixed body 501 is fixedly installed on the top of the inner cavity of the sedimentation tank 101, and the wall scraping motor 502 is nested inside the fixed body 501. The output shaft of the wall scraping motor 502 is fixedly connected to the fixed column 503 via a coupling, while the scraper 504 is symmetrically installed on both sides of the fixed column 503 for easy starting of the wall scraping motor 502. After starting, the output shaft of the wall scraping motor 502 drives the transmission shaft to rotate, and the transmission shaft then drives the fixed column 503 to rotate, causing the scraper 504 to rotate in close contact with the inner wall of the sedimentation tank 101, thereby removing the stains adsorbed on the inner wall.
[0025] The general working principle of this utility model can be referenced as follows: First, wastewater treatment workers use existing collection pipes to inject wastewater into the sedimentation tank 101 through the inlet 103, and place a sludge storage tank below the sludge removal port 303. After a period of time, the sludge and impurities in the wastewater will settle onto the separation plate 308 at the bottom of the sedimentation tank 101. Next, the separation motor 304 is started, and its output shaft drives the transmission shaft to rotate, which in turn drives the gear 305 to rotate. The gear 305 drives the meshing rack 307 to move, causing the connecting plate 306, rack 307, and separation plate 308 to move into the sedimentation tank 101, thereby separating the settled water from the sludge. Subsequently, the cleaning motor 202 is started, and its output shaft drives the transmission shaft to rotate, which in turn drives the spiral push rod 203 to rotate. The spiral push rod 203 pushes the transmission rod 204 and the sludge reservoir 205 into the interior of the separation assembly 3, pushing the sludge deposited at the bottom of the sedimentation tank 101 into the interior of the second housing 301, and then discharging it into the storage tank through the cleaning port 303. After opening the valve 402, the water pump 403 is started. The water pump 403 sucks out the settled water from inside the sedimentation tank 101 through the connecting pipe 401 and transports it to other devices for further processing through the outlet pipe 404. Finally, the separation plate 308 is moved into the interior of the second housing 301, and the wall scraper motor 502 is started. The output shaft of the wall scraper motor 502 drives the transmission shaft to rotate, and the transmission shaft drives the fixed column 503 to rotate, causing the scraper 504 attached to the inner wall of the sedimentation tank 101 to rotate, thereby cleaning the stains on the inner wall of the sedimentation tank 101.
[0026] In summary, this invention, while reducing the requirements for equipment construction and maintenance to a certain extent, basically possesses the ability to quickly separate sediment from water. It can effectively prevent the bottom sediment from being carried out along with the water after sedimentation when it is extracted, thereby ensuring the cleanliness of the water after sedimentation and significantly improving the overall wastewater treatment efficiency. By effectively integrating the sedimentation component and the wall scraping component, the equipment can automatically clean the sludge on the inner wall of the sedimentation tank as needed during operation, avoiding excessive accumulation of dirt on the inner wall of the sedimentation tank. This can reduce the workload and time of manual operation and improve the cleaning efficiency of the facility, enabling the subsequently treated polluted water to meet relevant environmental protection requirements in the long term.
