Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, specifically to a reciprocating moving component for ultrasonic cleaning. Background Technology

[0002] In the field of industrial wastewater treatment, MBR technology has been widely used due to its high efficiency in solid-liquid separation and good effluent quality. As the core component of this technology, the MBR membrane will inevitably accumulate a large amount of pollutants such as sludge, microorganisms and their metabolites on its surface after a period of operation. These deposits will gradually clog the membrane pores, reduce the membrane flux, affect the treatment efficiency and effluent quality of the MBR system, and in severe cases, even lead to system failure.

[0003] In existing technologies, traditional MBR membrane cleaning methods mainly rely on manual operation of high-pressure water guns for rinsing. Manual cleaning requires operators to hold the high-pressure water gun and rinse the membrane modules one by one, which is a huge workload and a long cleaning process, resulting in increased downtime of the MBR system and affecting overall production efficiency. Furthermore, due to the limitations of manual operation, it is difficult to precisely control the rinsing range and intensity of the high-pressure water gun, resulting in some areas being incompletely cleaned while others may be over-cleaned, causing damage to the membrane material. In addition, it is difficult to achieve precise control of reciprocating movement during manual cleaning, which further reduces cleaning efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a reciprocating moving component for ultrasonic cleaning, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides an ultrasonic cleaning reciprocating moving assembly, including a housing, an ultrasonic reciprocating moving assembly installed on the top of the housing, the ultrasonic reciprocating moving assembly including a moving plate slidably connected to the top of the housing, two concave pulleys installed on the left and right sides of the moving plate, two anti-collision posts installed on the front and rear sides of the moving plate, stop posts installed at the four corners of the top of the housing, and ultrasonic components installed on both sides of the inner wall of the moving plate.

[0006] Furthermore, each ultrasonic component has a mounting block at its top, with a protrusion fixedly connected to the top of the mounting block. Guide wheels are installed on both sides of the mounting block. The ultrasonic component is slidably connected to the inner wall of the moving plate through the two guide wheels. A fixed outer shell is installed on one side of the outer wall of the housing. A two-way screw is rotatably connected to the inner wall of the fixed outer shell. Moving blocks are threadedly connected to both sides of the outer wall of the two-way screw. A guide rail is installed on one side of each moving block. Two baffles are installed at the bottom of each guide rail. The guide rail is slidably connected to the protrusion through the baffles.

[0007] Furthermore, both guide rails have curved panels attached to their opposite outer walls, and both curved panels are made of elastic material.

[0008] Furthermore, an ultrasonic generator is installed on one side of the outer wall of the enclosure, and an ultrasonic motion control component is installed on one side of the ultrasonic generator.

[0009] Furthermore, the movable plate is rotatably connected to the four concave pulleys, and the movable plate is slidably connected to the top of the box body via the four concave pulleys.

[0010] Furthermore, the moving plate is electrically connected to the ultrasonic moving control component, and the ultrasonic component is electrically connected to the ultrasonic generator.

[0011] Furthermore, the frequency range of the ultrasonic component is [15K, 40K], and the power intensity of the ultrasonic component is >700W / m. 3 .

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The ultrasonic reciprocating moving component adopts automated control, eliminating the need for frequent manual operation of the high-pressure water gun for rinsing. The PLC controller precisely controls the moving speed and path of the ultrasonic component, realizing the automation and high efficiency of the cleaning process. This not only greatly reduces the workload of operators, but also improves the accuracy and consistency of cleaning, and reduces the impact of human factors on the cleaning effect.

[0014] 2. The reciprocating moving component drives the ultrasonic transmitting device to reciprocate on both sides of the membrane, so that the ultrasonic energy can evenly cover the entire surface of the MBR membrane, ensuring that the entire surface of the MBR membrane is fully subjected to ultrasonic action, avoiding the occurrence of cleaning dead corners, and ensuring that all areas of the membrane are effectively cleaned.

[0015] 3. The adjustable components allow the two ultrasonic components to be positioned closer or further apart, which can accommodate the cleaning needs of membrane modules of different sizes. For small membrane modules, the two ultrasonic components can be brought closer together to concentrate ultrasonic energy for efficient cleaning. For large membrane modules, the distance between the two ultrasonic components can be increased to ensure that the entire surface of the membrane module receives sufficient ultrasonic cleaning.

[0025] 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.

[0026] Please see Figures 1-8This utility model provides a technical solution: an ultrasonic cleaning reciprocating moving assembly, including a housing 1. The housing 1 serves as the basic support structure for the entire assembly and also contains the cleaning fluid, forming a cleaning environment. An ultrasonic reciprocating moving assembly is installed at the top of the housing 1. The ultrasonic reciprocating moving assembly includes a moving plate 2 slidably connected to the top of the housing 1. Two concave pulleys 3 are installed on both the left and right sides of the moving plate 2, contacting the top of the housing 1. Relative sliding between the moving plate 2 and the housing 1 is achieved through rolling friction, reducing friction during movement and enabling the moving plate 2 to reciprocate smoothly. The concave pulleys 3 convert sliding friction into rolling friction. Dynamic friction significantly reduces the coefficient of friction, decreases energy loss, improves the movement efficiency of the moving plate 2, and extends the service life of both the moving plate 2 and the housing 1. Two anti-collision posts 4 are installed on both the front and rear sides of the moving plate 2. When the moving plate 2 approaches its limit position during reciprocating motion, the anti-collision posts 4 can contact other components on the housing 1, preventing the moving plate 2 from colliding with other components due to excessive movement, thus providing protection and effectively avoiding damage to the moving plate 2 due to collisions. This reduces equipment maintenance costs. Simultaneously, the anti-collision posts 4 improve the safety and reliability of the equipment, ensuring the smooth progress of the cleaning process. Stop posts 5 are installed at each of the four corners of the top. These stop posts 5, in conjunction with anti-collision posts 4, limit the movement range of the movable plate 2, clearly defining its movement boundaries. This allows operators to clearly understand the equipment's operating range, preventing excessive movement of the movable plate 2 and improving overall equipment safety. It ensures that the movable plate 2 reciprocates within a safe area, preventing it from exceeding the specified range and causing safety accidents or equipment damage. Ultrasonic components 6 are installed on both sides of the inner wall of the movable plate 2. The movable plate 2, acting as the carrier of the ultrasonic components 6, moves the ultrasonic components 6 at different positions on the top of the housing 1 through its own reciprocating movement, enabling the ultrasonic waves to move. The energy can cover a larger cleaning area, improving the comprehensiveness and efficiency of cleaning. Through cooperation with the concave pulley 3, smooth reciprocating motion is achieved. The ultrasonic component 6, as the core component of the cleaning process, generates ultrasonic waves and uses the cavitation effect of ultrasonic waves to clean the sludge and contaminants on the MBR membrane. Ultrasonic cleaning has the advantages of high efficiency, environmental protection, and non-destructive properties. It can effectively remove sludge and contaminants from the surface of the MBR membrane, restoring the membrane's permeability and filtration performance. Driven by the moving plate 2, the ultrasonic component 6 can play its role in different positions, achieving precise cleaning of different positions and improving the targeting and efficiency of cleaning.

[0027] See Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6Each ultrasonic component 6 has a mounting block 7 at its top, with a protrusion 8 fixedly connected to the top of the mounting block 7. Guide wheels 9 are mounted on both sides of the mounting block 7. The mounting block 7 connects the ultrasonic component 6 to the protrusion 8 and guide wheels 9, acting as a bridge to connect the ultrasonic component 6 to subsequent components. This ensures the stable installation and movement of the ultrasonic component 6 on the inner wall of the moving plate 2, guaranteeing the stability and reliability of the entire moving structure. The ultrasonic component 6 is slidably connected to the inner wall of the moving plate 2 via the two guide wheels 9. A fixed outer shell 10 is installed on one side of the outer wall of the housing 1. The guide wheels 9 are mounted on both sides of the mounting block 7, contacting the inner wall of the moving plate 2, guiding the ultrasonic component 6 to slide linearly on the inner wall of the moving plate 2. This reduces friction during the sliding process, lowers the coefficient of friction, reduces energy loss, and improves the ultrasonic efficiency. The motion efficiency of component 6 is such that the fixed housing 10 does not participate in the movement and remains stationary. A bidirectional lead screw 11 is rotatably connected to the inner wall of the fixed housing 10. Moving blocks 12 are threadedly connected to both sides of the outer wall of the bidirectional lead screw 11. A guide rail 13 is installed on one side of each moving block 12. By controlling the rotation direction and amplitude of the bidirectional lead screw 11, the distance between the ultrasonic components 6 can be flexibly changed to meet different cleaning needs. The bidirectional lead screw 11 is a 1605 left-right turn lead screw, controlled by a motor. When it is necessary to lock the position of the ultrasonic component 6, the motor stops driving the bidirectional lead screw 11 to rotate. When the motor stops, the threads between the bidirectional lead screw 11 and the moving blocks 12 engage, generating significant friction between the threaded surfaces to prevent the moving blocks 12 from sliding. The motor is a MINAS model. A5, after the movement stops, the electromagnetic brake is automatically activated when the motor is powered off, and mechanically locks the motor shaft to prevent the bidirectional lead screw 11 from rotating due to external force or inertia, ensuring the stability of the ultrasonic component 6. It can maintain the stability of the moving block 12 when it stops rotating, ensuring the accuracy of the position of the ultrasonic component 6. Each guide rail 13 has two baffles installed at the bottom. The guide rail 13 is slidably connected to the protrusion 8 through the baffles. The protrusion 8 cooperates with the baffle at the bottom of the guide rail 13. When the guide rail 13 moves, the protrusion 8 moves under the guidance of the baffle, driving the ultrasonic component 6 to perform linear motion, thereby realizing the adjustment of the position of the ultrasonic component 6.

[0028] See Figure 1 , Figure 3Both guide rails 13 have arc panels 14 connected to their opposite outer walls. Both arc panels 14 are made of elastic material. When the MBR membrane module is placed into the housing 1, the arc panels 14 apply appropriate force to the MBR membrane module through contact and elastic deformation, guiding the MBR membrane module to move to the correct position and realizing the function of correcting the position of the MBR membrane module. The arc panels 14 made of elastic material can buffer the MBR membrane module during the correction process, avoiding damage to the MBR membrane module. At the same time, its arc design can better fit the shape of the MBR membrane module, improving the accuracy and effectiveness of the correction.

[0029] See Figure 3 An ultrasonic generator 15, model HNG-252800-1, is installed on one outer wall of the housing 1. An ultrasonic motion control component 16, model HNC-4SH-3825Y, is installed on one side of the ultrasonic generator 15. The moving plate 2 is electrically connected to the ultrasonic motion control component 16. The ultrasonic motion control component 16 sends control signals to the moving plate 2 to control the direction and distance of movement of the ultrasonic component 6 on the inner wall of the moving plate 2, thereby controlling the position of the ultrasonic component 6, optimizing the cleaning effect, reducing errors and labor intensity of manual operation. The ultrasonic component 6 is electrically connected to the ultrasonic generator 15. The ultrasonic generator 15 can convert electrical energy into the electrical energy required by the ultrasonic component 6, ensuring the stable operation of the ultrasonic component 6 and improving the adaptability of cleaning.

[0030] See Figure 2 , Figure 3 The frequency range of ultrasonic component 6 is [15K, 40K], and the power intensity of ultrasonic component 6 is >700W / m. 3 The ultrasonic component 6 has a moving speed of v < 1 m / min, the membrane flux recovery rate of the membrane component is > 90%, and the PLC controller is model S7-1200.

[0031] Working principle: The movable plate 2 is slidably connected to the top of the box 1 via the concave pulley 3. The concave pulley 3 converts sliding friction into rolling friction, reducing friction and making the movable plate 2 move more smoothly. The anti-collision post 4 prevents the movable plate 2 from violently colliding with the box 1 during movement, playing a buffering and protective role. When the movable plate 2 moves to the limit position, the stop post 5 contacts the anti-collision post 4, limiting the range of movement of the movable plate 2 and preventing it from sliding out of the box 1. At the same time, the rotation of the bidirectional screw 11 drives the movable blocks 12 on both sides to move towards or away from each other. The movable blocks 12 drive the guide rail 13 to move. The guide rail 13 is slidably connected to the protrusion 8 through the baffle, pushing the ultrasonic component 6 to slide linearly on the inner wall of the movable plate 2 with the help of the guide wheel 9, realizing the movement of the ultrasonic component 6 closer to or further away from the inner wall of the movable plate 2, realizing the position adjustment and reciprocating movement of the ultrasonic component 6 during the cleaning process.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
