Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a cleaning device with adjustable angle. Background Technology

[0002] With the development of wastewater treatment technology, MBR technology has been widely used due to its high efficiency in solid-liquid separation and good effluent quality. However, MBR membranes are susceptible to contaminant adsorption and clogging during use, leading to decreased membrane flux, poorer treatment efficiency, and increased operating costs. To address these issues, MBR membrane cleaning equipment has emerged, aiming to restore membrane performance, extend membrane lifespan, ensure stable operation of the MBR system, and improve the efficiency and economy of wastewater treatment to meet increasingly stringent environmental requirements and wastewater treatment needs.

[0003] However, in actual cleaning work, the following technical problems have been found in existing cleaning equipment:

[0004] Most existing cleaning equipment lacks angle adjustment functionality. While some devices do offer this feature, it requires manual operation and is cumbersome, necessitating multiple disassembly and reassembly of components to achieve the desired angle. This prevents quick and convenient adjustments based on actual conditions during the cleaning process. Furthermore, many existing cleaning devices have nozzles fixed at a single height, limiting cleaning to a specific section of the MBR membrane. This prevents comprehensive cleaning of different height areas, especially for taller membrane modules, where the top and bottom become cleaning dead zones, resulting in uneven cleaning of the membrane surface.

[0005] In response to this technical problem, this application proposes an angle-adjustable cleaning device. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies, such as insufficient flexibility in angle adjustment and uneven cleaning due to a single cleaning height. This invention proposes an angle-adjustable cleaning device that allows for flexible angle adjustment based on the membrane's fouling status and location, ensuring complete coverage of the membrane by the cleaning solution, thus improving cleaning effectiveness and work efficiency. Simultaneously, it enables multi-height reciprocating coverage cleaning, effectively covering all vertical areas of the membrane, avoiding cleaning dead zones, and enhancing the comprehensiveness and uniformity of cleaning.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] An angle-adjustable cleaning device includes a frame. A gear is fixedly connected to the center of the top of the frame. The gear is connected to a telescopic rod via a rack. A shaft is fixedly connected to the bottom of the gear. The shaft passes through the top of the frame. A fixing rod is fixedly connected to the bottom of the shaft. A clamping plate is fixedly connected to the front and rear ends of the bottom of the fixing rod. A screw is slidably connected to the front and rear ends of the bottom of the fixing rod. A clamping plate is slidably connected to the bottom outer side of the screw. The clamping plate is connected to a membrane via an mounting rod. A stop is fixedly connected to the bottom of the screw. A threaded sleeve is threaded through the fixing rod and connected to the top of the screw.

[0009] Furthermore, a motor is fixedly connected to the middle of the left side of the outer wall of the frame. The drive end of the motor passes through the left side of the frame and is fixedly connected to a turntable. A round rod is fixedly connected to the right edge of the turntable. Limiting rods are fixedly connected to the front and rear ends of the left side of the inner wall of the frame. A slider is slidably connected to the outer wall of the limiting rod. A connecting block is fixedly connected to the side of the slider. A groove is opened on the right side of the connecting block. The inner wall of the groove is slidably connected to the round rod. A nozzle is installed on the right side of the slider.

[0010] Furthermore, a drain outlet is provided at the bottom right end of the inner wall of the frame.

[0011] Furthermore, the drain outlet is connected to the filter frame via an installation assembly.

[0012] Furthermore, the installation assembly includes an installation groove and an installation block. The installation groove is formed on the front and rear sides of the inner wall of the drain outlet, and the installation block is fixedly connected to the front and rear sides of the outer wall of the filter frame.

[0018] 2. In this utility model, multi-height reciprocating coverage cleaning is achieved. The motor drives the turntable and the round rod to convert the circular motion into the up-and-down reciprocating linear motion of the nozzle, so that the nozzle can clean the membrane at different heights, effectively covering all vertical areas of the membrane, improving the comprehensiveness and uniformity of cleaning, and avoiding cleaning dead corners.

[0027] 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.

[0028] Reference Figure 1 , Figure 2 and Figure 6 An embodiment of this utility model provides an angle-adjustable cleaning device, comprising a frame 1, a gear 12 fixedly connected to the top center of the frame 1, the gear 12 being connected to a telescopic rod 10 via a rack 11, a shaft 13 fixedly connected to the bottom of the gear 12, the shaft 13 penetrating the top of the frame 1, a fixing rod 14 fixedly connected to the bottom of the shaft 13, a clamping plate 15 fixedly connected to the front and rear ends of the bottom of the fixing rod 14, a screw 16 slidably connected to the front and rear ends of the bottom of the fixing rod 14, a clamping plate 18 slidably connected to the bottom outer side of the screw 16, the clamping plate 18 being connected to the membrane 21 via an mounting rod 20, a stop block 17 fixedly connected to the bottom of the screw 16, and a screw sleeve 19 threadedly connected to the top of the screw 16 through the fixing rod 14.

[0029] Specifically, the extension and retraction of the telescopic rod 10 drives the rack 11 to move linearly, thereby achieving stable rotation of the gear 12 through the meshing transmission between the rack 11 and the gear 12. The working principle is that when the telescopic rod 10 extends or retracts, the rack 11 moves horizontally accordingly. The teeth of the rack 11 interact with the teeth of the gear 12, causing the gear 12 to rotate around its central axis. This transmission method can accurately and stably transmit power, providing a basis for subsequent angle adjustment. A shaft 13 is fixedly connected to the bottom of the gear 12, passing through the top of the frame 1. A fixing rod 14 is fixedly connected to the bottom of the shaft 13. The gear 12 rotates... The shaft 13 rotates synchronously, which in turn drives the fixed rod 14 to rotate, thereby adjusting the angle of the component fixed on the fixed rod 14. By rotating the screw sleeve 19, the screw 16 can slide up and down along the fixed rod 14, thereby adjusting the distance between the second clamping plate 18 and the first clamping plate 15. It can firmly clamp mounting rods 20 of different sizes and has strong adaptability. Specifically, when it is necessary to clamp the mounting rod 20, the screw 16 is slid up and down, which drives the second clamping plate 18 to move closer to the first clamping plate 15, thereby clamping the mounting rod 20. Then, the screw sleeve 19 is rotated so that the second clamping plate 18 is fixed at a height that can clamp the mounting rod 20. Disassembly is performed by reversing the operation.

[0030] Reference Figure 2 , Figure 4 and Figure 5A motor 2 is fixedly connected to the middle of the left side of the outer wall of frame 1. The drive end of motor 2 passes through the left side of frame 1 and is fixedly connected to a turntable 3. A round rod 4 is fixedly connected to the right edge of turntable 3. Limiting rods 5 are fixedly connected to the front and rear ends of the left side of the inner wall of frame 1. Slider 6 is slidably connected to the outer wall of limiting rod 5. A connecting block 7 is fixedly connected to the side of slider 6. A groove 8 is opened on the right side of connecting block 7. The inner wall of groove 8 is slidably connected to round rod 4. A nozzle 9 is installed on the right side of slider 6. A drain outlet 23 is opened at the right end of the bottom side of the inner wall of frame 1. 3. The filter frame 25 is connected by the mounting component 24. The mounting component 24 includes a mounting groove 2401 and a mounting block 2402. The mounting groove 2401 is opened on the front and rear sides of the inner wall of the drain outlet 23. The mounting block 2402 is fixedly connected to the front and rear sides of the outer wall of the filter frame 25. The mounting block 2402 is slidably connected to the inner wall of the mounting groove 2401. A water collection tank 26 is slidably connected to the bottom front side of the frame 1. A water pipe 27 is installed on the left front side of the water collection tank 26. The top end of the water pipe 27 is connected to the nozzle 9. A guide groove 22 is opened on the left side of the bottom inner wall of the frame 1.

[0031] Specifically, motor 2 drives turntable 3 to perform circular motion, and the round rod 4 fixed to the edge of turntable 3 moves in a circular trajectory accordingly. Since the round rod 4 is slidably connected to the groove 8 on the connecting block 7, and the slider 6 is restricted by the limiting rod 5 to only move linearly in the vertical direction, when turntable 3 rotates, the round rod 4 slides in the groove 8, and its circular motion is converted into the up-and-down reciprocating linear motion of the slider 6 along the limiting rod 5, thereby driving the nozzle 9 installed on the right side of the slider 6 to move up and down, so that the nozzle 9 cleans the membrane 21 at different heights, effectively covering all vertical areas of the membrane 21, greatly improving the comprehensiveness and uniformity of cleaning, and avoiding cleaning dead corners. When installing filter frame 25, align the mounting block 2402 on filter frame 25 with the drain outlet. The installation is completed by inserting the filter frame 25 into the mounting groove 2401 on the inner wall of the filter 23, and then sliding the mounting block 2402 into the mounting groove 2401 to the appropriate position. For disassembly, the filter frame 25 can be easily removed by reversing the operation. This structure facilitates the installation and disassembly of the filter frame 25. During the cleaning process, the filter frame 25 can filter impurities in the cleaning solution, preventing impurities from re-contaminating the membrane 21. At the same time, it is convenient to clean and replace the filter frame 25. The cleaning liquid flows into the drain outlet 23 through the guide channel 22, and enters the water collection tank 26 after being filtered by the filter frame 25. The water collection tank 26 collects the filtered cleaning liquid and delivers it back to the nozzle 9 through the water pipe 27, realizing the recycling of the cleaning liquid, saving water resources, and reducing cleaning costs.

[0032] Working principle: During cleaning, the telescopic rod 10 extends and retracts, causing the rack 11 to move horizontally. The meshing of the rack 11 with the gear 12 causes the gear 12 to rotate, which in turn drives the shaft 13 and the fixed rod 14 to rotate, achieving angle adjustment. Rotating the screw sleeve 19 allows the screw 16 to slide up and down along the fixed rod 14, adjusting the distance between the clamping plate 2 18 and the clamping plate 15 to clamp or release the mounting rod 20. The motor 2 drives the turntable 3 to perform circular motion, causing the circular rod 4 fixed to its edge to also perform circular motion. The slider 6 is slidably connected to the groove 8 of the connecting block 7 and is restricted to vertical linear movement by the limiting rod 5, so it drives the nozzle 9 to move up and down to clean the membrane 21. When installing the filter frame 25, its mounting block 2402 is aligned with the mounting groove 2401 on the inner wall of the drain outlet 23 and inserted. The disassembly is done in reverse. The filter frame 25 is used to filter impurities in the cleaning liquid. The cleaned liquid flows into the drain outlet 23 through the guide groove 22, is filtered by the filter frame 25 and enters the water collection tank 26, and is then transported back to the nozzle 9 through the water pipe 27 to realize the recycling of the cleaning liquid.

Although the present utility model 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.
