Description

Technical Field

[0001] This utility model relates to the field of secondary sedimentation tank technology, specifically a track-synchronized snow removal roller brush device for secondary sedimentation tanks. Background Technology

[0002] The sedimentation tank after biological treatment is usually called a secondary sedimentation tank or final sedimentation tank. The function of the secondary sedimentation tank is to separate sludge from water, clarifying the mixed liquor, thickening the sludge, and returning the separated sludge to the biological treatment stage. Its effectiveness directly affects the effluent quality and the concentration of returned sludge. Poor sedimentation and thickening will increase the suspended solids in the effluent, thereby increasing the BOD concentration.

[0003] Utility model patent CN221244088U discloses an anti-freezing and snow removal system for secondary sedimentation tanks in wastewater treatment. The system includes a sludge scraper for the secondary sedimentation tank, comprising a working bridge and traveling on a platform via wheels. A snow blowing device is detachably connected to the scraper, fixed to the first side of the working bridge, for blowing away loose snow. During periods of severe winter weather, the snow blowing device, snow sweeping device, and snow melting device are connected to the secondary sedimentation tank sludge scraper. Utilizing the principle of continuous operation, the scraper automatically removes snow and spreads salt, ensuring stable production operation. In other seasons, the sludge scraper can be restored to its original condition by disassembling the snow blowing device, snow sweeping device, and snow melting device.

[0004] To remove snow from the secondary sedimentation tank, a snow removal device is used. Although the snow removal system in the aforementioned patent ensures the automatic operation of the system, the application of de-icing agent will corrode the tank surface, and the melted snow is prone to freezing in the ultra-low temperature environment, affecting the use of the secondary sedimentation tank track. To address these issues, we provide a secondary sedimentation tank track synchronous snow removal roller brush device. Utility Model Content

[0005] The purpose of this invention is to provide a synchronous snow removal roller brush device for a secondary sedimentation tank track, so as to solve the problems mentioned in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a secondary sedimentation tank track-synchronized snow removal roller brush device, comprising a sludge scraper frame and a fixed frame. The surface of the fixed frame is provided with an adjustment mechanism, the adjustment mechanism including a lifting plate slidably connected to the fixed frame. The surface of the lifting plate is sequentially provided with a cleaning mechanism, an ice-crushing mechanism, and a scraping mechanism. The cleaning mechanism includes a power rod rotatably connected to the lifting plate, and a snow removal brush is fixedly connected to the bottom end of the power rod. The ice-crushing mechanism includes a connecting frame and an eccentric cam, and an ice-breaking roller is rotatably connected inside the connecting frame. The scraping mechanism includes a triangular scraper.

[0007] Preferably, a mounting bracket is fixedly connected to the surface of the fixed frame, the mounting bracket is slidably connected to the sludge scraper frame, and the mounting bracket is assembled and connected to the sludge scraper frame by bolts. A motor is fixedly connected to the surface of the lifting plate, and the output end of the motor is fixedly connected to the power rod. The fixed frame is fixedly installed in front of the sludge scraper frame by the mounting bracket and bolts.

[0008] Preferably, a lifting frame is slidably connected to the top of the fixed frame, and the bottom of the lifting frame is fixedly connected to the lifting plate. An electric push rod for controlling the lifting of the lifting frame is fixedly connected to the surface of the fixed frame, and a protective cover is fixedly connected to the surface of the lifting plate. The electric push rod causes the lifting frame to move the lifting plate up and down, thereby controlling whether the snow removal device contacts the track.

[0009] Preferably, a reducer is fixedly connected to the surface of the lifting plate, and the output end of the reducer is fixedly connected to the eccentric cam. A driven sprocket is fixedly connected to the input end of the reducer, and a transmission sprocket is fixedly connected to the surface of the power rod. The transmission sprocket and the driven sprocket are connected by a chain drive. The power rod drives the transmission sprocket to rotate, and through the chain drive, the driven sprocket controls the input end of the reducer to rotate. The reducer controls the eccentric cam to rotate slowly.

[0010] Preferably, a first telescopic spring is fixedly connected to the surface of the connecting frame, a push plate is fixedly connected to the top of the first telescopic spring, a limit rod is provided inside the first telescopic spring, the bottom end of the limit rod is fixedly connected to the connecting frame, and the connecting frame is slidably connected to the push plate. The push plate transmits pressure downward, which changes the magnitude of the thrust of the first telescopic spring. The change in the magnitude of the thrust of the first telescopic spring allows the ice-breaking roller to generate an impact force on the ice surface and break the ice surface.

[0011] Preferably, a sliding rod is fixedly connected to the surface of the push plate, and the sliding rod is slidably connected to the lifting plate. A receiving plate is fixedly connected to the top of the sliding rod, and an eccentric cam is slidably connected to the receiving plate. A second telescopic spring is sleeved on the outside of the sliding rod, and the two ends of the second telescopic spring are fixedly connected to the lifting plate and the receiving plate, respectively. By rotating the eccentric cam, the receiving plate is driven to move up and down, so that the receiving plate drives the push plate to move up and down through the sliding rod.

[0012] Preferably, a positioning rod is slidably connected to the surface of the triangular scraper, and the top end of the positioning rod is fixedly connected to the lifting plate. A third telescopic spring is sleeved on the outside of the positioning rod, and the two ends of the third telescopic spring are fixedly connected to the lifting plate and the triangular scraper respectively. The third telescopic spring provides a thrust to the triangular scraper, so that the triangular scraper is in close contact with the track surface, and pushes the snow and ice on the track surface to both sides, ensuring the normal operation of the sludge scraper.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This application uses a fixed frame to securely install the snow removal device onto the sludge scraper frame. During the non-snowfall season, the snow removal device can be disassembled and its height adjusted by sliding a lifting plate up and down on the fixed frame surface. When there is no snowfall, the snow removal device is raised; during snowfall, it is brought into contact with the secondary sedimentation tank track. The snow removal brush is rotated via a power rod to clean the snow in front of the sludge scraper, improving the device's snow removal efficiency. The rotation of the eccentric cam provides downward pressure to the connecting frame, causing it to squeeze the ice-breaking roller. The ice-breaking roller then hammers the ice blocks, shattering them and improving the device's ice-breaking effect. A triangular scraper separates the snow and ice scraped by the snow removal brush to both sides of the sludge scraper, clearing snow from the track and effectively preventing equipment slippage. Furthermore, it does not use chemical agents, avoiding corrosion of the tank surface and improving the stability of the secondary sedimentation tank operation.

[0015] 2. This application uses a mounting bracket and bolts to fix the fixing frame to the front of the snow scraper frame. The electric motor controls the rotation of the power rod, thereby improving the convenience of the snow removal brush rotating to sweep snow. The electric push rod causes the lifting frame to move up and down, controlling whether the snow removal device is in contact with the track. The power rod drives the transmission sprocket to rotate, and through the chain transmission, the driven sprocket controls the input end of the reducer to rotate. The reducer controls the eccentric cam to rotate slowly, and the push plate transmits pressure downward, changing the magnitude of the thrust of the first telescopic spring. The change in the magnitude of the thrust of the first telescopic spring allows the ice-breaking roller to generate impact force on the ice surface and break the ice.

[0016] 3. This application uses a limiting rod to fix the positions of the push plate and the connecting frame, preventing lateral displacement of the connecting frame during operation and improving the stability of the device. The connecting frame can also position the first telescopic spring, preventing it from bending outwards and improving its stability. The rotation of the eccentric cam drives the receiving plate to move up and down, causing the receiving plate to move the push plate up and down via a sliding rod. The second telescopic spring provides an upward thrust to the receiving plate, ensuring close contact between the receiving plate and the eccentric cam. A positioning rod limits the position of the triangular scraper, and a third telescopic spring provides thrust to the triangular scraper, ensuring close contact between the triangular scraper and the track surface. This pushes snow and ice debris from the track surface to both sides, ensuring the normal operation of the sludge scraper. Attached Figure Description

[0022] 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.

[0023] like Figure 1 - Figure 4 As shown, this utility model provides a technical solution for a track-synchronized snow removal roller brush device for a secondary sedimentation tank, including a sludge scraper frame 1 and a fixing frame 3. The fixing frame 3 is fixedly installed together with the sludge scraper frame 1 to fix the snow removal device, and the snow removal device can be disassembled during the non-snowfall season.

[0024] The mounting bracket 2 is fixedly connected to the surface of the fixed frame 3. The mounting bracket 2 is slidably connected to the sludge scraper frame 1, and the mounting bracket 2 is assembled and connected to the sludge scraper frame 1 by bolts. The fixed frame 3 is fixedly installed in front of the sludge scraper frame 1 by the mounting bracket 2 and bolts.

[0025] The surface of the fixed frame 3 is provided with an adjustment mechanism 4. The adjustment mechanism 4 includes a lifting plate 401 that is slidably connected to the fixed frame 3. The height of the snow removal device is adjusted by the lifting plate 401 sliding up and down on the surface of the fixed frame 3. When there is no snowfall, the snow removal device is raised, and when there is snowfall, the snow removal device is brought into contact with the secondary sedimentation tank track.

[0026] The top of the fixed frame 3 is slidably connected to the lifting frame 402, and the bottom of the lifting frame 402 is fixedly connected to the lifting plate 401. The surface of the fixed frame 3 is fixedly connected to the electric push rod 403 that controls the lifting of the lifting frame 402. The surface of the lifting plate 401 is fixedly connected to the protective cover 404. The electric push rod 403 causes the lifting frame 402 to drive the lifting plate 401 to move up and down, controlling whether the snow removal device contacts the track. The protective cover 404 protects the power mechanism on the surface of the lifting plate 401 to prevent damage to the electrical equipment caused by snowfall.

[0027] The surface of the lifting plate 401 is sequentially provided with a sweeping mechanism 5, an ice crushing mechanism 6, and a scraping mechanism 7. The sweeping mechanism 5 includes a power rod 502 that is rotatably connected to the lifting plate 401. A snow removal brush 501 is fixedly connected to the bottom end of the power rod 502. The snow removal brush 501 is rotated by controlling the power rod 502 to clean the snow in front of the scraper and improve the snow removal efficiency of the device.

[0028] A motor 503 is fixedly connected to the surface of the lifting plate 401, and the output end of the motor 503 is fixedly connected to the power rod 502. The motor 503 controls the rotation of the power rod 502, thereby improving the convenience of the snow removal brush 501 to rotate and sweep snow.

[0029] Both the electric push rod 403 and the motor 503 are electrically connected to the controller of the sludge scraper. The controller can control the operation of the electric push rod 403 and the motor 503. The sedimentation tank is equipped with monitoring equipment to detect the internal conditions of the sedimentation tank. When snow accumulation is detected on the track, the controller starts the electric push rod 403 and the motor 503 to perform snow removal operations on the track. The electric push rod 403 and the motor 503 are existing technologies, and their detailed parameters and models will not be described in detail in this application.

[0030] The ice-breaking mechanism 6 includes a connecting frame 602 and an eccentric cam 609. An ice-breaking roller 601 is rotatably connected inside the connecting frame 602. The rotation of the eccentric cam 609 provides downward pressure to the connecting frame 602, causing the connecting frame 602 to squeeze the ice-breaking roller 601. The ice-breaking roller 601 hammers the ice block, crushing the whole block of ice and improving the ice-breaking effect of the device.

[0031] The ice-breaking roller 601 can be made of rigid materials with a certain degree of elasticity, such as rubber, silicone, and plastic, which not only avoids damage to the sedimentation tank by the ice-breaking roller 601, but also ensures the effect of hammering to break ice.

[0032] A reducer 610 is fixedly connected to the surface of the lifting plate 401, and the output end of the reducer 610 is fixedly connected to the eccentric cam 609. A driven sprocket 611 is fixedly connected to the input end of the reducer 610. A transmission sprocket 612 is fixedly connected to the surface of the power rod 502, and the transmission sprocket 612 and the driven sprocket 611 are connected by chain drive. The power rod 502 drives the transmission sprocket 612 to rotate, and through the chain drive, the driven sprocket 611 controls the input end of the reducer 610 to rotate. The reducer 610 controls the eccentric cam 609 to rotate slowly.

[0033] The reducer 610 can be a gear differential reducer or a worm gear reducer, and the reducer 610 is a finished device. This application will not go into detail about its detailed parameters and model.

[0034] A first telescopic spring 603 is fixedly connected to the surface of the connecting frame 602. A push plate 604 is fixedly connected to the top of the first telescopic spring 603. A limit rod 605 is provided inside the first telescopic spring 603. The bottom end of the limit rod 605 is fixedly connected to the connecting frame 602, and the connecting frame 602 is slidably connected to the push plate 604. The push plate 604 transmits pressure downward, changing the magnitude of the thrust of the first telescopic spring 603. This change in the magnitude of the thrust of the first telescopic spring 603 allows the ice-breaking roller 601 to generate impact force on the ice surface and break the ice. The limit rod 605 fixes the positions of the push plate 604 and the connecting frame 602, preventing the connecting frame 602 from shifting laterally during operation and improving the stability of the device. The connecting frame 602 can also position the first telescopic spring 603, preventing it from bending outward and improving the stability of the first telescopic spring 603 in use.

[0035] A sliding rod 606 is fixedly connected to the surface of the push plate 604, and the sliding rod 606 is slidably connected to the lifting plate 401. A receiving plate 607 is fixedly connected to the top of the sliding rod 606, and an eccentric cam 609 is slidably connected to the receiving plate 607. A second telescopic spring 608 is sleeved on the outside of the sliding rod 606, and the two ends of the second telescopic spring 608 are fixedly connected to the lifting plate 401 and the receiving plate 607 respectively. By rotating the eccentric cam 609, the receiving plate 607 is driven to move up and down, so that the receiving plate 607 drives the push plate 604 to move up and down through the sliding rod 606. The second telescopic spring 608 provides an upward thrust to the receiving plate 607, so that the receiving plate 607 and the eccentric cam 609 are kept in close contact.

[0036] The scraping mechanism 7 includes a triangular scraper 701, which separates the snow and ice scraped by the snow removal brush 501 to both sides of the scraper and removes the snow from the track.

[0037] A positioning rod 702 is slidably connected to the surface of the triangular scraper 701, and the top end of the positioning rod 702 is fixedly connected to the lifting plate 401. A third telescopic spring 703 is sleeved on the outside of the positioning rod 702, and the two ends of the third telescopic spring 703 are fixedly connected to the lifting plate 401 and the triangular scraper 701 respectively. The positioning rod 702 limits the triangular scraper 701, and the third telescopic spring 703 provides a thrust to the triangular scraper 701, so that the triangular scraper 701 is in close contact with the track surface, pushing the snow and ice on the track surface to both sides, effectively preventing the equipment from slipping, and avoiding the use of chemical agents, thus avoiding corrosion of the pool surface and improving the stability of the secondary sedimentation tank operation.

[0038] In use, this utility model works as follows: The mounting bracket 3 is fixedly installed in front of the scraper frame 1 using the mounting bracket 2 and bolts. When snow accumulates on the track, the electric push rod 403 causes the lifting frame 402 to move the lifting plate 401 downwards, controlling the snow removal device to contact the track. The motor 503 is started, controlling the power rod 502 to rotate, causing the snow removal brush 501 to rotate and sweep the snow in front. Simultaneously, the power rod 502 drives the transmission sprocket 612 to rotate. Through chain transmission, the driven sprocket 611 controls the input end of the reducer 610 to rotate. The reducer 610 controls the eccentric cam 609 to rotate slowly, through the eccentric cam... The rotation of wheel 609 drives the receiving plate 607 to move up and down. Through the transmission of sliding rod 606, it drives push plate 604 to move up and down. The push plate 604 transmits pressure downward, changing the magnitude of the thrust of the first telescopic spring 603. This causes the ice-breaking roller 601 to impact the ice surface and break it. The third telescopic spring 703 provides thrust to the triangular scraper 701, making the triangular scraper 701 closely contact the track surface. This pushes the snow and ice on the track surface to both sides, ensuring the normal operation of the sludge scraper. Through all these methods, the snow on the track is cleared, effectively preventing equipment slippage. Furthermore, no chemical agents are used, avoiding corrosion of the pool surface.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
