Description

Technical Field

[0001] This utility model relates to the technical field of sludge cleaning equipment, and in particular to a sludge cleaning device for the bottom of a pool and a disinfection pool. Background Technology

[0002] In the field of wastewater treatment, wastewater tanks (such as disinfection tanks) accumulate a large amount of viscous sludge at the bottom after long-term operation. If not cleaned regularly, this will seriously affect the wastewater treatment effect, reduce the wastewater treatment efficiency, and even cause the wastewater treatment system to fail. Existing mechanical sludge cleaning devices often use direct suction, such as the sludge cleaning device for a wastewater sedimentation tank with patent number CN202222835152.6. This device mainly uses the combined action of rotating spiral blades and a sludge collection hood to collect the sludge at the bottom of the tank to one end of the spiral blades, and then sucks away the collected sludge through a branch pipe. However, this sludge cleaning method has some problems: on the one hand, because the sludge has a complex composition, high viscosity, and may contain fibrous impurities, direct suction can easily cause temporary or continuous blockage in the pipes, affecting the continuity of operation and thus affecting the sludge cleaning efficiency and effect; on the other hand, overcoming blockage may require a high-power suction pump, leading to increased energy consumption.

[0003] Based on this, the applicant is considering designing a sludge cleaning device and disinfection tank that can reduce the risk of clogging. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is: how to provide a sludge cleaning device and disinfection pool that can reduce the risk of clogging.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A device for cleaning sludge at the bottom of a pool includes a hopper, a drive mechanism, and a suction mechanism.

[0007] The bucket body includes a collection chamber, a collection port is provided on the front side of the collection chamber, a crushing roller assembly is rotatably installed in the collection chamber, and a suction space is formed between the crushing roller assembly and the rear side of the collection chamber; the driving mechanism is used to drive the crushing roller assembly to rotate; the suction mechanism is connected to the suction space.

[0008] The working principle and advantages of the sludge cleaning device and disinfection tank at the bottom of the pool in this technical solution are as follows:

[0009] When cleaning the sludge at the bottom of the disinfection tank, the sludge enters the collection chamber through the hopper's collection port. The drive mechanism rotates the crushing roller assembly to crush the sludge, breaking down its stickiness and fibrous structure, thus reducing the risk of blockage in the pipeline. The crushed sludge then enters the suction space and is smoothly discharged through the suction mechanism. This solution reduces the possibility of blockage during the suction process by pre-crushing the sludge, ensuring the continuity of the cleaning operation and improving the effectiveness and efficiency of sludge treatment. Furthermore, the increased fluidity of the crushed sludge reduces suction resistance, eliminating the need for a high-power suction pump and reducing operating costs.

[0010] Furthermore, the crushing roller assembly includes an upper crushing roller and a lower crushing roller arranged vertically. Both the upper crushing roller and the lower crushing roller include a rotating shaft rotatably mounted inside the bucket body. Several crushing wheels and transmission gears are fixedly connected to the rotating shaft. The transmission gears of the upper crushing roller and the lower crushing roller mesh with each other.

[0011] Furthermore, the drive mechanism includes a fixedly installed drive motor, and a drive gear is fixedly connected to the output shaft of the drive motor. The drive gear meshes with the transmission gear of the upper crushing roller.

[0012] Furthermore, the bucket body is provided with a receiving cavity, and the upper crushing roller and the lower crushing roller drive gear are located in the receiving cavity.

[0013] Furthermore, the drive motor is fixedly installed on the top side of the bucket body, the drive gear extends into the receiving cavity, and a mounting cover is detachably connected to the top side of the bucket body, the mounting cover covering the drive motor.

[0014] Furthermore, the suction mechanism includes a suction tube communicating with the suction space and a suction pump connected to the suction tube.

[0015] Furthermore, a connecting rod is fixedly connected to the top side of the bucket body.

[0016] Furthermore, the bottom side of the bucket body is inclined.

[0017] Furthermore, the bottom side of the bucket is rotatably connected to movable wheels.

[0018] The disinfection pool includes the aforementioned pool bottom sludge cleaning device and a pool body. A central seat is provided at the center of the pool body, and a rotating mechanism is installed on the central seat. The rotating mechanism is driven by a rotating truss extending above the edge of the pool body. The free end of the rotating truss is provided with a traveling wheel that contacts the top side of the edge of the pool body. The pool bottom sludge cleaning device is fixedly installed on the rotating truss. Attached Figure Description

[0033] Refer to together Figures 1 to 4 A device for cleaning sludge at the bottom of a pool, comprising a bucket body 100, a drive mechanism, and a suction mechanism;

[0034] The bucket body 100 includes a collection chamber 110, a collection port is provided on the front side of the collection chamber 110, a crushing roller assembly 200 is rotatably installed in the collection chamber 110, and a suction space is formed between the crushing roller assembly 200 and the rear side of the collection chamber 110; a driving mechanism is used to drive the crushing roller assembly 200 to rotate; the suction mechanism is connected to the suction space.

[0035] In this embodiment, when cleaning the sludge at the bottom of the disinfection tank, the sludge enters the collection chamber 110 through the collection port of the bucket 100. The drive mechanism drives the crushing roller group 200 to rotate, crushing the sludge, breaking down its stickiness and fibrous structure, and reducing the risk of blockage in the pipeline. The crushed sludge enters the suction space and is then smoothly discharged by the suction mechanism. This solution reduces the possibility of blockage during the suction process by pre-crushing the sludge, ensuring the continuity of the cleaning operation and improving the effect and efficiency of sludge treatment. Moreover, the fluidity of the crushed sludge is enhanced, and the suction resistance is reduced, so efficient suction can be achieved without configuring a high-power suction pump 16, reducing operating costs.

[0036] Preferably, such as Figures 1 to 4As shown, the crushing roller assembly 200 includes an upper crushing roller and a lower crushing roller arranged vertically. Both the upper and lower crushing rollers include a rotating shaft 210 rotatably mounted inside the bucket body 100. Several crushing wheels 211 and transmission gears 230 are fixedly connected to the rotating shaft 210. The transmission gears 230 of the upper and lower crushing rollers mesh with each other. When the drive mechanism drives the transmission gear 230 of any crushing roller to rotate, the meshing of the transmission gears 230 drives the other crushing roller to rotate in the opposite direction. The reverse rotation of the two rollers forms a shearing force field. When the sludge passes through the gap between the two rollers, it is torn and crushed by the crushing wheels 211 on the rotating shaft 210, thereby achieving effective crushing of the sludge. The several crushing wheels 211 on the upper and lower crushing rollers are staggered. The crushing wheels 211 are provided with multiple protrusions in the circumferential direction to improve the crushing effect. The double roller meshing transmission realizes automatic reverse rotation without the need for an additional drive device, reducing energy consumption.

[0037] Preferably, such as Figures 1 to 4 As shown, the drive mechanism includes a fixedly mounted drive motor 300, and a drive gear 310 is fixedly connected to the output shaft of the drive motor 300. The drive gear 310 meshes with the transmission gear 230 of the upper crushing roller. The drive motor 300 can drive the transmission gear 230 of the upper crushing roller to rotate through the drive gear 310, thereby driving the crushing roller assembly 200 to operate in a coordinated manner. Through the meshing between the transmission gears 230, it can be ensured that the crushing roller assembly 200 operates at a suitable speed and torque, efficiently crushing the sludge, while ensuring the stability and reliability of the operation of the crushing roller assembly 200.

[0038] Preferably, such as Figures 1 to 4 As shown, the bucket body 100 is provided with a receiving cavity 120, and the upper crushing roller and the lower crushing roller drive gear 230 are located in the receiving cavity 120; the receiving cavity 120 forms a relatively closed installation space, which can effectively protect the drive gear 230 inside and improve the overall compactness and neatness of the device.

[0039] Preferably, such as Figures 1 to 4 As shown, the drive motor 300 is fixedly installed on the top side of the bucket body 100, and the drive gear 310 extends into the receiving cavity 120. A mounting cover 130 is detachably connected to the top side of the bucket body 100, covering the drive motor 300. The drive motor 300 is installed on the top side of the bucket body 100, which facilitates installation and maintenance without affecting the internal spatial layout and overall structural compactness of the bucket body 100. The drive gear 310 extends into the receiving cavity 120 and can precisely mesh with the transmission gear 230 located in the receiving cavity 120 to ensure effective power transmission. The detachable mounting cover 130 on the top side of the bucket body 100 allows for quick disassembly when needed for inspection, maintenance, or replacement of the drive motor 300, improving the maintainability of the equipment. The mounting cover 130 covers the drive motor 300, providing protection.

[0040] Preferably, such as Figure 1 and Figure 2 As shown, the suction mechanism includes a suction pipe 400 connected to the suction space and a suction pump 16 connected to the suction pipe 400. One end of the suction pipe 400 is connected to the suction space, and the other end is connected to the suction pump 16. When the suction pump 16 is started, it can extract the crushed sludge from the suction space through the suction pipe 400 and transport it to a designated location, thereby achieving efficient cleaning and transportation of sludge.

[0041] Preferably, such as Figure 1 and Figure 2 As shown, a connecting rod 500 is fixedly connected to the top side of the bucket body 100; the connecting rod 500 on the bucket body 100 facilitates the connection of the device as a whole with other devices or components, such as slide rails, handles or rotating devices.

[0042] Preferably, such as Figure 1 and Figure 2 As shown, the bottom side of the hopper 100 is inclined; when the bottom side of the hopper 100 is inclined, a scraper is formed, which allows the sludge to enter the collection chamber 110 more smoothly, facilitating the centralized collection and treatment of the sludge.

[0043] Preferably, such as Figure 1 and Figure 2 As shown, a movable wheel 140 is rotatably connected to the bottom side of the bucket body 100; the movable wheel 140 can reduce the friction between the bucket body 100 and the bottom of the pool, making it easier for the entire pool bottom sludge cleaning device to move on the bottom of the pool, protecting the bucket body 100 and the surface of the pool bottom, and extending the service life of the device.

[0044] Specifically, the rotating shaft 210 is connected to the bucket body 100 through the bearing 220, making the rotation of the rotating shaft 210 smoother.

[0045] Refer to together Figures 1 to 5As shown, the disinfection pool includes the aforementioned pool bottom sludge cleaning device and a pool body 10. A central seat 11 is located at the center of the pool body 10, and a rotating mechanism 12 is mounted on the central seat 11. The rotating mechanism 12 is connected to a rotating truss 13 extending above the edge of the pool body 10. A traveling wheel 14 is located at the free end of the rotating truss 13, contacting the top edge of the pool body 10. The pool bottom sludge cleaning device is fixedly mounted on the rotating truss 13. The rotating mechanism 12 drives the rotating truss 13 to rotate, and the traveling wheel 14 contacts the top edge of the pool body 10, providing stable support and guidance during the rotation of the rotating truss 13, ensuring the stability of the pool bottom sludge cleaning device during movement and preventing swaying or displacement of the device during cleaning. The pool bottom sludge cleaning device is fixedly mounted... Mounted on the rotating truss 13, the sludge at the bottom of the pool can be continuously crushed and sucked up as the truss 13 rotates and moves, improving the efficiency of sludge cleaning and shortening the cleaning time. Specifically, multiple sludge cleaning devices are fixedly connected to the rotating truss 13 to improve sludge cleaning efficiency. More specifically, a suction pump 16 is fixedly connected to the rotating truss 13, and a suction main pipe 15 is fixedly connected to the suction end of the suction pump 16. The suction pipes 400 of all the sludge cleaning devices are connected to the suction main pipe 15, allowing one suction pump 16 to act on multiple sludge cleaning devices at the same time, reducing the manufacturing cost of the disinfection pool. More specifically, the sludge cleaning devices are fixedly connected to the rotating truss 13 through connecting rods 500.

[0046] More specifically, such as Figure 6 As shown, in another embodiment, the drive mechanism includes a drive wheel 600 fixedly connected to the rotating shaft 210 of the upper or lower crushing roller. When the sludge cleaning device moves at the bottom of the pool, it can drive the drive wheel 600 to rotate, thereby driving the upper or lower crushing roller to rotate. In turn, the meshing transmission gears 230 drive the crushing roller group 200 to work together to achieve the crushing treatment of sludge. Compared with the drive mechanism using the drive motor 300, the manufacturing and operating costs of this solution are lower, but the operating stability and crushing efficiency are not as good as the drive mechanism using the drive motor 300.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions 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 solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
