Description

Technical Field

[0001] This utility model relates to the field of secondary sedimentation tank wall cleaning technology, and in particular to a novel cleaning device for secondary sedimentation tanks in sewage treatment. 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, clarify the mixed liquor, concentrate the sludge, and return the separated sludge to the biological treatment section. The secondary sedimentation tank is an important component of the activated sludge system. It is used to clarify the mixed liquor and recover and concentrate the activated sludge. Its effectiveness directly affects the effluent quality and the concentration of returned sludge. If the sedimentation and concentration are not effective, the suspended solids in the activated sludge will increase in the effluent, thereby increasing the BOD concentration of the effluent. At the same time, the concentration of returned sludge will also decrease, thereby reducing the concentration of the mixed liquor in the aeration tank and affecting the purification effect.

[0003] Because the water flow velocity on the outer wall of the secondary sedimentation tank is low, algae are more likely to grow. To avoid negative impacts on the operation of the sewage treatment system and water quality, algae need to be cleaned regularly. Most of the existing secondary sedimentation tank outer wall cleaning devices use fixed installation for their walking and cleaning mechanisms. Since the outer wall of the secondary sedimentation tank is long, it needs to be constructed using multiple sets of templates. The outer wall of the secondary sedimentation tank is prone to having inclined or concave surfaces. Fixed walking and cleaning mechanisms are not effective at cleaning algae on inclined or concave surfaces. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of existing secondary sedimentation tank outer wall cleaning devices, which mostly use fixed installation for the walking mechanism and cleaning mechanism. Since the outer wall of the secondary sedimentation tank is long, it needs to be cast with multiple sets of templates. The outer wall of the secondary sedimentation tank is prone to have inclined or concave surfaces. Fixed walking and cleaning mechanisms are not effective in cleaning algae on inclined or concave surfaces. This invention provides a new cleaning device for sewage treatment secondary sedimentation tanks.

[0005] The objective of this utility model is achieved through the following technical solution: A novel cleaning device for a secondary sedimentation tank in wastewater treatment includes a shell, a first fixed block installed inside the shell, a movable block installed on one side of the first fixed block via a first spring, a turntable installed at the bottom of the movable block, a first rotating rod extending outside the shell installed at the bottom of the turntable, the first rotating rod being rotatably connected to the shell, a first bearing seat installed at the end of the first rotating rod away from the shell, a rotatable second rotating rod installed on the first bearing seat, an L-shaped plate installed at the end of the second rotating rod away from the first bearing seat, a second bearing seat installed at the end of the L-shaped plate away from the second rotating rod, a motor installed on the second bearing seat, and the power output end of the motor being rotatably connected to the second bearing seat. Furthermore, the power output end of the motor passes through the second bearing seat and is equipped with a brush roller corresponding to the outer wall of the secondary sedimentation tank. By setting up a first rotating rod, a first bearing seat, a second rotating rod, an L-shaped plate, and a second bearing seat, the motor can drive the brush roller to rotate and clean the outer wall of the secondary sedimentation tank. When cleaning the outer wall of the secondary sedimentation tank, the brush roller can change its tilt state according to the shape of the outer wall, thus achieving effective cleaning of the tilted surface of the outer wall of the secondary sedimentation tank. At the same time, a first fixed block, a first spring, and a movable block are set up to cooperate so that the first spring is stressed when the motor drives the brush roller to tilt. This facilitates the motor and the brush roller to reset when they travel to the normal and flat outer wall of the secondary sedimentation tank, thereby ensuring the effective use of the motor and the brush roller and improving the cleaning effect on the outer wall of the secondary sedimentation tank.

[0006] The motor is located inside the housing, and the bottom wall of the housing has a corresponding movable cavity. By setting the movable cavity, the motor can be guaranteed to have enough room to move, meet the tilting requirements of the motor and the brush roller, avoid interference between the motor and the bottom wall of the housing, and at the same time, the motor being located inside the housing can play a certain role in waterproofing.

[0007] A further technical solution is to install two sets of first walking motors inside the shell, with the power output ends of the two sets of first walking motors extending to the outside of the shell and equipped with walking wheels. By setting the first walking motors, the shell is driven to move stably on the outer wall of the secondary sedimentation tank.

[0008] A further technical solution involves two sets of through slots at the bottom of the shell. A mounting base corresponding to each through slot is installed on the inner bottom wall of the shell. A movable fixed rod is installed within each through slot. A rotatable clamping wheel is installed at the lower part of the fixed rod. Slider blocks that slidably connect to the through slots are installed on both sides of the fixed rod. A second spring is installed between the mounting base and the fixed rod. A slidable sliding rod is installed on the mounting base. One end of the sliding rod passes through the second spring and connects to the fixed rod. A limit block is installed at the end of the sliding rod away from the second spring. By configuring the sliding rod, sliders, and through slots to cooperate, the fixed rod can move within the through slots under the pressure of the second spring, thereby allowing the clamping wheel on the fixed rod to move tightly against the inner wall of the secondary sedimentation tank, ensuring stable operation of the equipment.

[0009] A further technical solution involves installing two sets of second traveling motors inside the housing. The power output ends of the second traveling motors extend to the bottom and are equipped with auxiliary wheels. Clamping wheels and auxiliary wheels are located on both sides of the traveling wheels. The clamping wheels and auxiliary wheels located on both sides of the traveling wheels ensure the stability of the housing's movement on the secondary sedimentation tank wall. The clamping wheels, which contact the inner wall of the secondary sedimentation tank, and the auxiliary wheels, which contact the outer wall of the secondary sedimentation tank, work together to clamp the secondary sedimentation tank wall, thereby improving the cleaning effect of the brush roller on the concave and convex surfaces of the outer wall of the secondary sedimentation tank. At the same time, it meets the needs of traveling and cleaning on the outer wall of secondary sedimentation tanks with different shapes and curvatures.

[0010] A further technical solution involves installing a solar panel on the top of the casing and a battery inside the casing. The solar panel is connected to the battery via a charging controller, and the output of the battery is connected to the motor and the first walking motor. By combining the solar panel and the battery, solar energy can be used for charging, making reasonable use of clean energy and achieving energy conservation and emission reduction.

[0011] This utility model has the following advantages: By setting a first rotating rod, a first bearing seat, a second rotating rod, an L-shaped plate, and a second bearing seat, this utility model enables the motor to drive the brush roller to rotate and clean the outer wall of the secondary sedimentation tank. When cleaning the outer wall of the secondary sedimentation tank, the tilt state can be changed according to the shape of the outer wall, thus achieving effective cleaning of the tilted surface of the outer wall of the secondary sedimentation tank. By setting a sliding rod, a slider, and a through groove to cooperate, the fixed rod can move in the through groove under the pressure of the second spring, so that the clamping wheel on the fixed rod can move in close contact with the inner wall of the secondary sedimentation tank, ensuring the stable operation of the equipment.

[0022] like Figures 1-3As shown, a novel cleaning device for a secondary sedimentation tank in wastewater treatment includes a housing 1. A first fixed block 2 is installed inside the housing 1. A movable block 4 is mounted on one side of the first fixed block 2 via a first spring 3. A turntable 5 is mounted at the bottom of the movable block 4. A first rotating rod 6 extending outside the housing 1 is mounted at the bottom of the turntable 5. The first rotating rod 6 is rotatably connected to the housing 1. A first bearing seat 7 is mounted at the end of the first rotating rod 6 away from the housing 1. A rotatable second rotating rod 8 is mounted on the first bearing seat 7. An L-shaped plate 9 is mounted at the end of the second rotating rod 8 away from the first bearing seat 7. A second bearing seat 10 is mounted at the end of the L-shaped plate 9 away from the second rotating rod 8. A motor 11 is mounted on the second bearing seat 10. The power output end of the motor 11 is rotatably connected to the second bearing seat 10, and the motor 11's power output... The force output end passes through the second bearing seat 10 and is equipped with a brush roller 13 corresponding to the outer wall of the secondary sedimentation tank. By setting up the first rotating rod 6, the first bearing seat 7, the second rotating rod 8, the L-shaped plate 9, and the second bearing seat 10, the motor 11 can drive the brush roller 13 to rotate and clean the outer wall of the secondary sedimentation tank. The brush roller 13 can change its tilt according to the shape of the outer wall, effectively cleaning the inclined surface of the outer wall. Simultaneously, the first fixed block 2, the first spring 3, and the movable block 4 cooperate to apply force to the first spring 3 when the motor 11 drives the brush roller 13 to tilt. This facilitates the reset of the motor 11 and the brush roller 13 when they reach the normally flat outer wall of the secondary sedimentation tank, ensuring the effective use of the motor 11 and the brush roller 13 and improving the cleaning effect on the outer wall of the secondary sedimentation tank.

[0023] The motor 11 is located inside the housing 1. The bottom wall of the housing 1 has a movable cavity 12 corresponding to the motor 11. By setting the movable cavity 12, the motor 11 can have enough room to move, meet the tilting requirements of the motor 11 and the brush roller 13, avoid interference between the motor 11 and the bottom wall of the housing 1, and at the same time, the motor 11 being located inside the housing 1 can play a certain role in waterproofing.

[0024] Two sets of first walking motors 15 are installed inside the shell 1. The power output ends of the two sets of first walking motors 15 extend to the outside of the shell 1 and are equipped with walking wheels 14. By setting the first walking motors 15, the shell 1 is driven to move stably on the outer wall of the secondary sedimentation tank.

[0025] Two sets of through slots 21 are provided at the bottom of the housing 1. The inner bottom wall of the housing 1 is equipped with mounting seats 18 corresponding to the through slots 21. A movable fixed rod 19 is installed in the through slot 21. A rotatable clamping wheel 20 is installed at the lower part of the fixed rod 19. Slider blocks 23 that are slidably connected to the through slot 21 are installed on both sides of the fixed rod 19. The sliders 23 can make the fixed rod 19 move stably in the through slot 21. A second spring 24 is installed between the mounting seat 18 and the fixed rod 19. A slidable slide rod 22 is installed on the mounting seat 18. One end of the slide rod 22 passes through the second spring 24 and is connected to the fixed rod 19. A limit block is installed at the end of the slide rod 22 away from the second spring 24. By setting the slide rod 22, slider 23 and through slot 21 to cooperate, the fixed rod 19 can move in the through slot 21 under the pressure of the second spring 24, so that the clamping wheel 20 on the fixed rod 19 can move close to the inner side wall of the secondary sedimentation tank, ensuring the stable operation of the equipment.

[0026] Two sets of second travel motors 25 are installed inside the housing 1. The power output end of the second travel motor 25 extends to the bottom of 1 and is equipped with an auxiliary wheel 26. The clamping wheel 20 and the auxiliary wheel 26 are located on both sides of the travel wheel 14. The clamping wheel 20 and the auxiliary wheel 26 located on both sides of the travel wheel 14 can ensure the stability of the housing 1 moving on the wall of the secondary sedimentation tank. The clamping wheel 20, which is in contact with the inner wall of the secondary sedimentation tank, and the auxiliary wheel 26, which is in contact with the outer wall of the secondary sedimentation tank, cooperate to clamp the wall of the secondary sedimentation tank, thereby improving the cleaning effect of the brush roller 13 on the concave and convex surfaces of the outer wall of the secondary sedimentation tank, and at the same time meeting the needs of walking and cleaning on the outer wall of the secondary sedimentation tank with different shapes and curvatures.

[0027] A solar panel 16 is installed on the top of the housing 1, and a battery 17 is installed inside the housing 1. The solar panel 16 is connected to the battery 17 through a charging controller. The output terminal of the battery 17 is connected to the motor 11 and the first walking motor 15 respectively. By setting the solar panel 16 and the battery 17 together, solar energy can be used for charging, making reasonable use of clean energy and achieving energy conservation and emission reduction.

[0028] The working process of this utility model is as follows: When using this device to clean the outer wall of the secondary sedimentation tank, the first walking motor 15 and the second walking motor 25 are started first. The first walking motor 15 and the second walking motor 25 drive the housing 1 to move on the outer wall of the secondary sedimentation tank through the walking wheel 14 and the auxiliary wheel 26 respectively. The motor 11 drives the brush roller 13 to rotate and clean the outer wall of the secondary sedimentation tank. When the outer wall of the secondary sedimentation tank has an inclined surface or an inward concave surface, the clamping wheel 20 in contact with the inner wall of the secondary sedimentation tank and the auxiliary wheel 26 in contact with the outer wall of the secondary sedimentation tank cooperate to clamp the housing 1 against the wall of the secondary sedimentation tank. With the cooperation of the first rotating rod 6, the first bearing seat 7, the second rotating rod 8, the L-shaped plate 9 and the second bearing seat 10, the motor 11 drives the brush roller 13 to change its tilt state according to the shape of the outer wall of the secondary sedimentation tank, so as to effectively clean the inclined surface of the outer wall of the secondary sedimentation tank.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
