Description

Technical Field

[0001] This application relates to the field of water tank cleaning technology, and in particular to a device for cleaning algae from the walls of a secondary sedimentation tank. Background Technology

[0002] In the field of wastewater treatment, secondary sedimentation tanks are key structures for achieving sludge-water separation, and the cleanliness and maintenance of their tank walls directly affect treatment efficiency and water quality safety. For a long time, due to prolonged immersion in eutrophic water, the tank walls are highly susceptible to the growth of moss, algae, and slimy biofilms. These deposits not only reduce the effective volume of the tank and affect the quality of the effluent, but their aging and detachment can also enter the effluent system, leading to excessive suspended solids levels.

[0003] Currently, most water plants still rely on traditional manual cleaning methods for cleaning the walls of secondary sedimentation tanks. This method requires emptying the tank and having workers enter to wash with high-pressure water guns or mechanically scrape away debris. This method has significant drawbacks, including low efficiency, high labor intensity, high safety risks, and the need to shut down operations. Furthermore, some attempts at fixed scraping devices or chemical dosing methods also suffer from problems such as numerous cleaning dead spots and the potential for secondary pollution. Therefore, the industry urgently needs a tank wall cleaning technology and device that can operate online, is highly automated, provides thorough cleaning, and is environmentally friendly. Utility Model Content

[0004] This application provides a device for cleaning algae from the walls of secondary sedimentation tanks to address the following technical problems: For cleaning the walls of secondary sedimentation tanks, most water plants still rely on traditional manual cleaning methods. This method requires emptying the tank and having workers enter to perform high-pressure water jet washing or mechanical scraping, which has significant drawbacks such as low efficiency, high labor intensity, high safety risks, and the need to shut down operations. Furthermore, some attempts to use fixed scraping devices or chemical agent dosing methods also suffer from problems such as numerous cleaning dead spots and the potential for secondary pollution.

[0005] This application provides a device for cleaning algae from the walls of a secondary sedimentation tank, employing the following technical solution:

[0006] A device for cleaning algae from the walls of a secondary sedimentation tank includes a top connecting frame, a bracket with an inner frame, a first movable bracket, a second movable bracket, a cleaning component, and an algae-aiding guide component. The outer side of the top connecting frame is bolted to the top of the secondary sedimentation tank. The bracket with the inner frame is fixedly connected to the outer side of the top connecting frame. The first movable bracket is threaded onto the outer side of the bracket with the inner frame. The second movable bracket is movably connected to the top of the top connecting frame. The cleaning component is installed below the first movable bracket, and the algae-aiding guide component is installed below the second movable bracket.

[0007] In one feasible technical solution of this application, the cleaning component includes a positioning frame, a cleaning brush plate and a compression spring. The positioning frame is fixedly connected to the bottom of the first movable bracket, the cleaning brush plate is slidably connected to the inner side of the positioning frame, and the outer side of the cleaning brush plate abuts against the wall of the secondary sedimentation tank. The two sides of the compression spring are fixedly connected to the surfaces of the positioning frame and the cleaning brush plate, respectively.

[0008] In one feasible technical solution of this application, the moss-aiding guide assembly includes a long support rod, a short support rod, a waterproof cover, a support frame, and a metal brush roller. The long support rod is fixedly connected to the bottom of the second movable bracket, the short support rod is fixedly connected to the bottom of the second movable bracket on the other side, the support frame is fixedly connected to the bottom of the long support rod and the short support rod, the waterproof cover is screwed onto some parts of the support frame, and the metal brush roller is rotatably connected to the inner side of the support frame.

[0009] In one feasible technical solution of this application, a hinge plate and a compensating support rod are further provided on the opposite sides of the first movable support and the second movable support. The hinge plate is fixedly connected to the surface of the first movable support and the second movable support respectively, and the compensating support rod is hinged to the inner side of the hinge plate.

[0010] In one feasible technical solution of this application, a first stepper motor is also provided inside the waterproof cover, and the output end of the first stepper motor is fixedly connected to one end of the metal brush roller.

[0012] In one feasible technical solution of this application, the support frame is provided in two sets, and the two sets of support frames are staggered below the pool top connecting frame, and the surface of the upper support frame does not contact the surface of the long support rod.

[0013] In summary, this application includes at least one of the following beneficial technical effects:

[0014] This device is directly fixed to the top of the tank, allowing cleaning operations to be performed while the secondary sedimentation tank is operating normally. It completely overcomes the fundamental drawback of traditional manual cleaning, which requires emptying the tank and interrupting production, significantly improving the continuous operation capability and overall efficiency of the wastewater treatment system. By incorporating movable cleaning brushes and high-speed rotating metal rollers, the cleaning brushes, under the action of compression springs, remain in constant contact with the tank wall, ensuring uniform and comprehensive cleaning and effectively solving the cleaning dead zones problem inherent in fixed scraper devices. A second stepper motor drives a fine screw, causing the movable support and cleaning components to automatically reciprocate along the tank wall. Simultaneously, the first stepper motor drives the metal rollers to rotate at high speed, eliminating the need for operators to enter the tank and completely removing safety risks associated with working at heights or in confined spaces during manual cleaning, while also significantly reducing labor intensity. The compression spring design in the cleaning components gives the cleaning brushes a certain degree of self-adaptability, compensating for minor unevenness in the tank wall and ensuring continuous effective contact. Furthermore, the design of the hinge plate and compensating support rod enhances the overall rigidity and stability of the movable support system, ensuring smooth operation of the device under complex working conditions.

[0030] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0031] This application discloses a device for cleaning algae from the walls of a secondary sedimentation tank. (Refer to...) Figures 1 to 5The algae removal device for the secondary sedimentation tank includes a top connecting frame 1, a bracket with an inner frame 2, a first movable bracket 3, a second movable bracket 4, a cleaning component 5, and an algae-aiding guide component 6. The outer side of the top connecting frame 1 is connected to the top of the secondary sedimentation tank by bolts. The bracket with an inner frame 2 is fixedly connected to the outer side of the top connecting frame 1. The first movable bracket 3 is threaded onto the outer side of the bracket with an inner frame 2. The second movable bracket 4 is movably connected to the top of the top connecting frame 1. The cleaning component 5 is installed below the first movable bracket 3, and the algae-aiding guide component 6 is installed below the second movable bracket 4.

[0032] The cleaning component 5 includes a positioning frame 51, a cleaning brush 52, and a compression spring 53. The positioning frame 51 is fixedly connected to the bottom of the first movable bracket 3. The cleaning brush 52 is slidably connected to the inner side of the positioning frame 51, and the outer side of the cleaning brush 52 abuts against the wall of the secondary sedimentation tank. The two sides of the compression spring 53 are fixedly connected to the surfaces of the positioning frame 51 and the cleaning brush 52, respectively.

[0033] Under the constant pressure provided by the compression spring 53, the cleaning brush 52 always maintains a tight fit with the pool wall. When the pre-treated pool wall comes into contact with the cleaning brush 52, all loosened but not completely detached biofilm and moss are thoroughly scraped off, restoring the pool wall to a clean state.

[0034] The moss-aiding guide assembly 6 includes a long support rod 61, a short support rod 62, a waterproof cover 63, a support frame 64, and a metal brush roller 65. The long support rod 61 is fixedly connected to the bottom of the second movable bracket 4, the short support rod 62 is fixedly connected to the bottom of the second movable bracket 4 on the other side, the support frame 64 is fixedly connected to the bottom of the long support rod 61 and the short support rod 62, the waterproof cover 63 is screwed onto the support frame 64, and the metal brush roller 65 is rotatably connected to the inside of the support frame 64.

[0035] The moss-aiding guide component 6, located at the front, is the first to operate. Its built-in stepper motor 9 drives the metal brush roller 65 to rotate at high speed. Under centrifugal force, the rotating brush roller throws water against the pool wall to create an impact, initially peeling off some of the attached substances; on the other hand, its rigid bristles directly agitate and remove stubborn moss, preparing for subsequent deep cleaning.

[0036] A hinge plate 7 and a compensating support rod 8 are also provided on the opposite sides of the first movable support 3 and the second movable support 4. The hinge plate 7 is fixedly connected to the surface of the first movable support 3 and the second movable support 4 respectively, and the compensating support rod 8 is hinged to the inner side of the hinge plate 7.

[0037] The hinge plate 7 and the compensating support rod 8 ensure the stability of the linkage frame, while the compression spring 53 enables the cleaning brush plate 52 to have self-adjusting capability, effectively compensating for minor unevenness on the surface of the pool wall, thereby achieving comprehensive, efficient, and thorough cleaning of the secondary sedimentation tank wall.

[0038] The waterproof cover 63 is also equipped with a first stepper motor 9, and the output end of the first stepper motor 9 is fixedly connected to one end of the metal brush roller 65.

[0039] The outer side of the inner frame bracket 2 is also provided with a second stepper motor 10 and a fine screw 11. The output end of the second stepper motor 10 is fixedly connected to one end of the fine screw 11, and the outer thread surface of the fine screw 11 is screwed to the bottom of the first movable bracket 3.

[0040] Two sets of support frames 64 are provided, and the two sets of support frames 64 are staggered below the pool top connecting frame 1, and the surface of the upper support frame 64 does not contact the surface of the long support rod 61.

[0041] The usage process of the algae removal device for the secondary sedimentation tank wall in this embodiment is roughly as follows:

[0042] First, the top connecting frame 1 is fixedly installed on the top of the secondary sedimentation tank using bolts. The inner frame bracket 2 is fixed to the outside of this frame, forming the main support structure. The second stepper motor 10 starts, driving the fine screw 11 to rotate. Through the threaded engagement with the fine screw 11, the first movable bracket 3 can move horizontally back and forth along the inner frame bracket 2. The second movable bracket 4 is movably connected to the top of the top connecting frame 1, and is interconnected with the first movable bracket 3 through a hinge plate 7 and a compensating support rod 8, forming a stable linkage frame to ensure the synchronicity and overall stability of both during movement. Simultaneously, the moss-aiding guide component 6 begins to operate. This component is fixed to the bottom of the second movable bracket 4 via a long support rod 61 and a short support rod 62. Its support frame 64 contains a metal brush roller 65 driven by the first stepper motor 9. The first stepper motor 9 is sealed within a waterproof cover 63. The two sets of support frames 64 are staggered, ensuring they do not interfere with each other. A high-speed rotating metal brush roller 65 uses centrifugal force to initially rinse and loosen the algae on the pool wall, serving as a pre-cleaning agent and guiding the main cleaning path. Following this, the cleaning assembly 5, mounted at the bottom of the first movable support 3, performs the main cleaning task. The cleaning brush plate 52, under the continuous action of the compression spring 53, remains firmly in contact with the pool wall. As the device moves, the cleaning brush plate 52 thoroughly scrapes the pre-treated pool wall. The design of the compression spring 53 provides the cleaning brush plate 52 with adaptive clamping force, effectively compensating for any minor unevenness in the pool wall and ensuring uniform and thorough scraping.

[0043] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
