Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, specifically a ceramic filter plate cleaning device. Background Technology

[0002] Ceramic filters are based on the principle of capillary action, using microporous ceramics as the filter medium. They are a highly efficient and energy-saving solid-liquid separation device designed using the capillary action principle of numerous small micropores in microporous ceramics. Under negative pressure, the microporous ceramic filter plate has the characteristic of being water-permeable but air-impermeable. Creating a vacuum inside the ceramic filter plate generates a pressure difference with the outside, causing suspended materials in the feed tank to be adsorbed onto the ceramic filter plate under negative pressure. Solid materials cannot pass through the microporous ceramic filter plate and are retained on the surface, while liquids, due to the vacuum pressure difference and the hydrophilicity of the ceramic filter plate, pass smoothly into the gas-liquid distribution device (vacuum tank) for discharge or recycling, thus achieving solid-liquid separation. However, ceramic filter plates are easily clogged after prolonged use. Existing cleaning methods mostly involve rinsing with water, but the rinsing effect is poor and incomplete. To better clean the filter plates, a ceramic filter plate cleaning device is proposed.

[0003] As disclosed in CN222445713U, a ceramic filter plate cleaning device includes a base, an annular frame, ear brackets, a hydraulic cylinder, a roller frame, a crossbeam, a connecting rod, and an ultrasonic transducer. The annular frame is symmetrically arranged on the left and right sides of the ceramic filter and is fixedly installed on the ground via the base. The roller frame is slidably connected to the annular frame, and a crossbeam is fixedly installed between the two roller frames. An ultrasonic transducer corresponding to the ceramic filter plate is installed on the crossbeam via a connecting rod. The annular frame is also provided with ear brackets. One end of the hydraulic cylinder is hinged to the ear bracket, and the other end is hinged to the roller frame, so that the extension and retraction of the hydraulic cylinder can drive the roller frame to slide around the annular frame.

[0004] Although it simplifies the cleaning process, avoids cleaning dead corners, and can automatically lift the ultrasonic transducer out of the water after cleaning, thereby reducing the labor intensity of workers;

[0005] However, the existing cleaning device does not solve the problems of inconvenient linkage center expansion clamping and fixing of filter plates and circumferential rotation adjustment of the contact position between the filter plates and the cleaning liquid during use. It is not conducive to moving the filter plates for input and output and uniform cleaning of the filter plates, which affects the convenience of clamping and fixing the filter plates and the cleaning effect. Utility Model Content

[0006] The purpose of this utility model is to provide a filter plate cleaning device for ceramic filters, so as to solve the problems mentioned in the background art, which are not convenient for the linkage center to expand outward to fix the filter plate and to adjust the contact position between the filter plate and the cleaning liquid by circumferential rotation. This is not conducive to the movement input and output of the filter plate and the uniform cleaning of the filter plate, thus affecting the convenience of filter plate clamping and fixing and the cleaning effect.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a ceramic filter plate cleaning device, comprising an ultrasonic cleaner and hydraulic cylinders. Hydraulic cylinders are symmetrically mounted on the outer wall of the ultrasonic cleaner. Each hydraulic cylinder has a first push arm mounted at its output end.

Gears are mounted on the surface of each drive shaft. Each support ring has a movably mounted limit ring inside it. Each limit ring has a toothed ring mounted on its side wall, and the toothed ring meshes with the gear. A support seat is mounted on the inner wall of each toothed ring.

[0008] Preferably, each of the side walls of the support base is equipped with a placement block, and each of the placement blocks is equipped with three sets of C-shaped blocks at equal intervals.

[0009] Preferably, each of the bearing seats is equipped with an electric push rod inside, and each of the electric push rods is equipped with a second push arm at its output end.

[0010] Preferably, three sets of long connecting arms with equal spacing are provided on the side wall of the second push arm. Each long connecting arm has a linkage shaft at the end near the second push arm, and the long connecting arm is movably connected to the second push arm through the linkage shaft.

[0011] Preferably, each of the long connecting arms is provided with a short connecting arm at the end away from the second push arm, and each of the short connecting arms is provided with a hinge shaft on the side of the long connecting arm close to the long connecting arm, and the short connecting arm is movably connected to the long connecting arm through the hinge shaft.

[0013] Preferably, each of the short connecting arms is provided with a clamping block at the end away from the C-shaped block, and the clamping block is fixedly connected to the short connecting arm.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the cleaning device not only realizes the convenient linkage center outward expansion clamping and fixing of the filter plate and the circumferential rotation adjustment of the contact position between the filter plate and the cleaning liquid, which facilitates the movement input and output of the filter plate and the uniform cleaning of the filter plate, but also improves the convenience of clamping and fixing the filter plate and the cleaning effect.

The working principle of the ultrasonic cleaner is to convert the high frequency electrical signal into mechanical vibration through the transducer, generate cavitation effect in the liquid, and use the impact force of the bubble bursting to peel off the dirt, thereby cleaning the dirt on the filter plate and inside the filter plate. After cleaning, the hydraulic cylinder is opened in the opposite direction, the hydraulic cylinder drives the filter plate to move upward, then the electric push rod is turned off, and the filter plate can be removed.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figure 1-6 This utility model provides an embodiment of a ceramic filter plate cleaning device, including an ultrasonic cleaner 1 and a hydraulic cylinder 2. The hydraulic cylinder 2 is symmetrically installed on the outer wall of the ultrasonic cleaner 1. The hydraulic cylinder 2 plays a power driving role. The output end of each hydraulic cylinder 2 is equipped with a first push arm 3. A bearing arm 4 is provided above the ultrasonic cleaner 1, and the first push arm 3 is connected to the bearing arm 4. Multiple sets of connecting arms 5 with equal spacing are installed at the bottom end of the bearing arm 4. The bottom end of each connecting arm 5 is equipped with a bearing block 6. The side wall of each bearing block 6 is equipped with a bearing ring 11. A stepper motor 7 is installed inside each bearing block 6. The stepper motor 7 plays a power driving role. The output end of each stepper motor 7 is equipped with a drive shaft 10. The surface of each drive shaft 10 is provided with a gear 8. A limit ring 23 is movably installed inside each bearing ring 11. A toothed ring 9 is installed on the side wall of each limit ring 23, and the toothed ring 9 meshes with the gear 8. A bearing seat 12 is installed on the inner wall of each toothed ring 9.

[0026] When the filter plate is immersed in the cleaning solution, in order to clean the filter plate more evenly and thoroughly, the stepper motor 7 is turned on, which drives the drive shaft 10 to rotate. The drive shaft 10 drives the gear 8 to rotate. With the meshing of the gear 8 and the gear ring 9, and the movable cooperation of the limiting ring 23 and the bearing ring 11, the gear 8 drives the bearing seat 12 to rotate through the gear ring 9. The bearing seat 12 drives the clamping block 13 and the filter plate to rotate, thereby adjusting the position of the filter plate and making the contact between the filter plate and the cleaning solution more even, thus improving the cleaning effect. This achieves convenient circumferential rotation adjustment of the contact position between the filter plate and the cleaning solution, facilitating uniform cleaning of the filter plate and improving the cleaning effect.

[0027] Each side wall of the support base 12 is equipped with a placement block 14, and each side wall of the placement block 14 is equipped with three sets of C-shaped blocks 21 at equal intervals.

[0028] Electric push rods 15 are installed inside the bearing seat 12. The electric push rods 15 serve as power drives. The output end of each electric push rod 15 is equipped with a second push arm 16. Three sets of long connecting arms 18 with equal spacing are provided on the side wall of each second push arm 16. A linkage shaft 17 is provided at the end of each long connecting arm 18 near the second push arm 16. The long connecting arm 18 is movably connected to the second push arm 16 through the linkage shaft 17.

[0029] Each end of the long connecting arm 18 away from the second push arm 16 is provided with a short connecting arm 20. Each short connecting arm 20 is provided with a hinge shaft 19 on the side of the long connecting arm 18, and the short connecting arm 20 is movably connected to the long connecting arm 18 through the hinge shaft 19. Each end of the short connecting arm 20 near the C-block 21 is provided with a connecting shaft 22, and the short connecting arm 20 is movably connected to the C-block 21 through the connecting shaft 22.

[0030] Each end of the short connecting arm 20 away from the C-block 21 is provided with a clamping block 13, and the clamping block 13 is fixedly connected to the short connecting arm 20.

[0031] Remove the ceramic filter plate to be cleaned and place its center position onto the surface of the clamping block 13. Open the electric push rod 15, which drives the second push arm 16 to move. The second push arm 16 then drives the long connecting arm 18 to rotate via the linkage shaft 17. The long connecting arm 18 then drives the short connecting arm 20 to rotate around the connecting shaft 22 via the hinge shaft 19. The C-shaped block 21 provides support for the short connecting arm 20, which in turn drives the clamping block 13 to rotate. The three sets of clamping blocks 13 rotate outwards, clamping and fixing the filter plate from its center position. Add cleaning fluid into the ultrasonic cleaner 1. Then open the hydraulic cylinder 2, which drives the first push arm 3 to retract. The first push arm 3 then drives the bearing arm 4, connecting arm 5, and bearing block 6. The filter plate is moved downwards and immersed in the cleaning solution. Then, the ultrasonic cleaner 1 (a product similar to the Dekang Ultrasonic-1026W) is turned on to clean the filter plate. The working principle of the ultrasonic cleaner 1 is to convert high-frequency electrical signals into mechanical vibrations through a transducer, generating a cavitation effect in the liquid. The impact force of the bursting bubbles is used to peel off the dirt, thereby cleaning the dirt on and inside the filter plate. After cleaning, the hydraulic cylinder 2 is opened in the reverse direction, which drives the filter plate to move upwards. Then, the electric push rod 15 is closed, and the filter plate can be removed. This achieves convenient linkage center expansion clamping and fixing of the filter plate, which facilitates the input and output of filter plate movement and improves the convenience of filter plate clamping and fixing.

[0032] Working principle: The filter plate of the ceramic filter to be cleaned is removed and placed on the surface of the clamping block 13 at its center. The electric push rod 15 drives the second push arm 16 to move. The second push arm 16 drives the long connecting arm 18 to rotate through the linkage shaft 17. The long connecting arm 18 drives the short connecting arm 20 to rotate around the connecting shaft 22 through the hinge shaft 19. The C-shaped block 21 provides support for the short connecting arm 20. The short connecting arm 20 drives the clamping block 13 to rotate. The three sets of clamping blocks 13 rotate outward, clamping and fixing the filter plate from the center position. Cleaning fluid is added into the ultrasonic cleaner 1. The hydraulic cylinder 2 drives the first push arm 3 to retract. The first push arm 3 drives the bearing arm 4, connecting arm 5, bearing block 6 and filter plate to move downward and immerse the filter plate in the cleaning fluid. Then, the ultrasonic cleaner 1 is turned on to clean the filter plate. The working principle of the ultrasonic cleaner 1 is to convert high-frequency electrical signals into mechanical vibrations through a transducer, generating a cavitation effect in the liquid. The impact force of the bursting bubbles is used to peel off dirt, thereby cleaning the filter plate and the dirt inside the filter plate. After cleaning, the hydraulic cylinder 2 is opened in reverse, and the hydraulic cylinder 2 drives the filter plate to move upward. Then, the electric push rod 15 is closed, and the filter plate can be removed. When the filter plate is immersed in the cleaning solution, in order to clean the filter plate more evenly and cleanly, the stepper motor 7 drives the drive shaft 10 to rotate, the drive shaft 10 drives the gear 8 to rotate, the gear 8 drives the bearing seat 12 to rotate through the gear ring 9, and the bearing seat 12 drives the clamping block 13 and the filter plate to rotate, thereby rotating and adjusting the position of the filter plate to make the filter plate contact with the cleaning solution more evenly, thereby improving the cleaning effect. The above is the complete usage of the ceramic filter plate cleaning device.
