Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a cleaning device for wastewater treatment ponds. Background Technology

[0002] Wastewater treatment ponds are the core facilities for wastewater treatment. They remove pollutants from water through processes such as sedimentation, aeration, and filtration. They come in various types and their structures include the pond body, inlet and outlet, and sludge removal system. They can efficiently purify wastewater and achieve compliant discharge or reuse, thus contributing to environmental protection and resource recycling.

[0003] During wastewater treatment, solid particles, organic matter, and microorganisms in the wastewater gradually accumulate at the bottom of the tank. If not cleaned in time, they will occupy the effective volume, reduce the hydraulic retention time, and lead to a decrease in treatment capacity. Therefore, cleaning devices are needed. However, with traditional cleaning devices, the sludge adhering to the tank walls will gradually thicken, reducing the effective treatment volume, shortening the hydraulic retention time, resulting in insufficient degradation of organic matter and substandard effluent quality. If the sewage pipes are difficult to disassemble due to rust, deformation, or design defects, the pipe or tank structure must be damaged during dredging, increasing maintenance time and costs.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0025] Example 1:

[0026] Reference Figures 1-4This is the first embodiment of the present invention. This embodiment provides a cleaning device for a sewage treatment tank, including a tank body 1. A horizontal plate 2 is fixedly connected to the top of the tank body 1. A protective cover 3 is fixedly connected to the top of the horizontal plate 2. A driving component 4 is provided on the top of the horizontal plate 2. A limiting component 5 is provided on one side of the driving component 4. A cleaning component 6 is provided on one side of the limiting component 5. A sewage pipe 7 is connected to the inner wall of the tank body 1. A connecting component 8 is provided at one end of the sewage pipe 7. An installation component 9 is provided on the outside of the connecting component 8.

[0027] The tank body 1 serves as the core container for sewage treatment and sludge storage. An internal storage tank 12 is provided to collect sludge and also to provide an installation foundation for the cleaning device. The horizontal plate 2 supports the drive assembly 4, the limiting assembly 5, and the protective cover 3, providing structural support for the entire device. The protective cover 3 covers the top of the horizontal plate 2, protecting the drive assembly 4 from external pollution such as rainwater and dust, thus extending the equipment's lifespan. The sewage pipe 7 connects the inside and outside of the tank body 1. An external sewage pump is used to pump out the scraped sludge and sewage, thus cleaning the sludge. It should be noted that a valve is installed on the outside of the sewage pipe 7.

[0028] The cleaning component 6 includes a connecting plate 61 disposed on one side of the limiting component 5. A scraper 62 is fixed to one side of the connecting plate 61 by screws, and a cleaning plate 63 is fixed to one side of the scraper 62 by screws.

[0029] The connecting plate 61 is used to connect the limiting component 5 and the scraper 62 to transmit driving force. The scraper 62 directly contacts the inner wall of the pool body 1. When the scraper 62 moves, it can scrape off the sludge attached to the pool wall. The cleaning plate 63 is located below and is close to the inner wall of the bottom of the pool body 1. It is used to scrape off the sludge on the bottom inner wall and assist the scraper 62 in further cleaning residual dirt and improving the cleaning effect.

[0030] The mounting component 9 includes a fixing block 91 disposed on the outside of the connecting component 8. The inner wall of the fixing block 91 is rotatably connected to a connecting rod 92 via a pivot, and a positioning plate 93 is fixed to the outside of the connecting rod 92.

[0031] The fixing block 91 is fixed to the bottom of the second flange 82, providing a fulcrum for the connecting rod 92 to rotate. The connecting rod 92 is rotatably connected to the fixing block 91 through a rotating shaft, which drives the positioning plate 93 to rotate, realizing the quick disassembly and installation of the first flange 81 and the second flange 82. The positioning plate 93 is fixed to the first flange 81 with screws, and its position is adjusted by rotating the connecting rod 92, simplifying the pipeline disassembly process.

[0032] Example 2:

[0033] This is the second embodiment of the present invention, which is based on the previous embodiment.

[0034] Specifically, the drive assembly 4 includes a motor 41 fixed to the top of the horizontal plate 2, and a threaded rod 42 is fixed to the output end of the motor 41.

[0035] Motor 41 provides a power source to drive the threaded rod 42 to rotate. The threaded rod 42 converts the rotational motion of motor 41 into linear motion, which drives the moving seat 51 to move left and right through the threaded transmission.

[0036] Specifically, the limiting component 5 includes a movable seat 51 threaded to the outside of the threaded rod 42, a slider 52 fixed on one side of the movable seat 51, and a slide rail 53 fixed on the top of the horizontal plate 2 for limiting the movement of the slider 52, and the top of the slide rail 53 is slidably connected to the inner wall of the slider 52.

[0037] The movable seat 51 is threadedly connected to the threaded rod 42. It moves left and right as the threaded rod 42 rotates, and drives the cleaning component 6 to move synchronously. The slider 52 and the slide rail 53 are used to limit the movement direction of the movable seat 51, ensuring that the cleaning component 6 moves only in a straight line and avoids deviation.

[0038] Specifically, the connecting component 8 includes a first flange 81 connected to one end of the drain pipe 7, and the outer side of the first flange 81 is fixed to one side of the positioning plate 93 by screws. A second flange 82 is connected to one side of the first flange 81, and the outer side of the second flange 82 is fixedly connected to the bottom of the fixing block 91.

[0039] The first flange 81 is used to connect the sewage pipe 7 and the second flange 82. It is fixed to the positioning plate 93 with screws to achieve a detachable connection of the pipe. The second flange 82 is used to connect the first flange 81 and the connecting pipe 10.

[0040] Example 3:

[0041] This is the third embodiment of the present invention, which is based on the first two embodiments.

[0042] Specifically, the inner wall of the second flange 82 is connected to a connecting pipe 10, and both the connecting pipe 10 and the drain pipe 7 are fixed with sealing gaskets 11.

[0043] Both the connecting pipe 10 and the sewage pipe 7 are fixed with sealing gaskets 11 to fill the gap at the flange connection and prevent sewage leakage. The connecting pipe 10 is used to connect an external sewage pump to extend the discharge path of the sewage pipe 7, making it easier to transport sludge to the designated treatment equipment.

[0044] Specifically, the inner wall of the pool 1 is provided with a storage tank 12 for collecting and storing sludge, and there are two sets of storage tanks 12.

[0045] Storage tank 12 is located on the inner wall of pool 1 to temporarily collect scraped sludge, preventing sludge from accumulating directly at the bottom of the pool and affecting sludge discharge efficiency, and facilitating centralized cleaning.

[0046] Specifically, a ladder 13 is fixed on one side of the pool body 1, and a guardrail 14 is provided on the top of the ladder 13. The number of ladders 13 and guardrails 14 is set to two.

[0047] Ladder 13 provides operators with access to pool 1 or equipment maintenance, while guardrail 14 prevents personnel from falling while climbing, thus improving operational safety.

[0048] During use, the operator climbs to the top via ladder 13, checks whether the protective cover 3 is closed, confirms that the motor 41 in the drive assembly 4 and the outer valve of the drain pipe 7 are closed, and checks whether the sealing gasket 11 is intact to prevent sewage leakage during subsequent operation. The motor 41 is started, and its output end drives the threaded rod 42 to rotate. Through the threaded transmission, the moving seat 51 moves horizontally along the slide rail 53. The moving seat 51 drives the scraper 62 and cleaning plate 63 to move synchronously through the connecting plate 61. The scraper 62 is close to the inner wall of the tank 1 to scrape off the attached sludge, and the cleaning plate 63 is close to the inner wall of the tank bottom to clean the residual dirt, improving the cleaning effect. The scraped sludge falls into the two sets of storage tanks 12 on the inner wall of the tank 1. After cleaning is completed, the motor 41 is turned off and the drain pipe is opened. 7. Connect the external valve and the external sludge pump to the connecting pipe 10. Start the sludge pump. The sludge in the storage tank 12 is pumped out of the tank through the drain pipe 7, the first flange 81, the second flange 82 and the connecting pipe 10. If it is necessary to disassemble the connecting pipe 10, first remove the screws at one end of the positioning plate 93 to release the limit on the positioning plate 93. At this time, rotate the connecting rod 92 in the mounting assembly 9. The positioning plate 93 is deflected through the rotating shaft so that the positioning plate 93 and the connecting rod 92 are not locked with the first flange 81. Thus, the first flange 81 and the second flange 82 can be disassembled, and then the connecting pipe 10 can be disassembled. After the discharge is completed, close the valve and the sludge pump. Check that there is no residual sludge on the inner wall of the tank 1 and the drain pipe 7. After confirming that the status of each component is normal, stop the machine.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
