Description

Technical Field

[0001] This invention belongs to the field of ceramic film processing technology, specifically a flat ceramic film surface treatment device. Background Technology

[0002] During filtration, contaminants accumulate on the surface of flat-sheet ceramic membranes, requiring periodic cleaning to restore flux. Currently, there are two main cleaning methods: online cleaning and centralized offline cleaning. Centralized cleaning typically involves arranging multiple ceramic membranes in parallel within a cleaning tank and using scrapers or high-pressure water for cleaning.

[0003] A Chinese patent with publication number CN112604505A discloses a flat ceramic membrane cleaning device and its usage method, including a base and a vertical plate. The vertical plate is equipped with a feeding mechanism for intermittently conveying the flat ceramic membrane. The feeding mechanism is equipped with a scraping mechanism for removing filter mud from the flat ceramic membrane. The feeding mechanism and the scraping mechanism are connected in a transmission manner. The feeding mechanism is also equipped with a chemical cleaning mechanism for backwashing the flat ceramic membrane. Based on the above mechanism, the flat ceramic membrane can be automatically transferred, saving time and labor, improving work efficiency, and integrating the scraping and chemical backwashing methods to reduce the number of devices for easier management. Furthermore, the scraping mechanism and the chemical cleaning mechanism improve the cleaning effect on the flat ceramic membrane.

[0004] However, such centralized cleaning devices still have many drawbacks, including the difficulty of adapting to the surface height differences of multi-layer membranes caused by cumulative installation errors and their own unevenness. This can easily lead to uneven contact between the scraper and the membrane, resulting in incomplete cleaning or scratching of the membrane surface.

[0005] Therefore, the present invention provides a flat ceramic film surface treatment device. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The flat ceramic film surface treatment device of the present invention includes a centralized cleaning box and an installation box installed in the centralized cleaning box; a bearing plate is fixedly connected in the installation box, and the bearing plate is used to support multiple ceramic films arranged in parallel at equal intervals;

[0008] It also includes a cleaning module, which is inserted into a centralized cleaning box for cleaning the surface of the ceramic diaphragm. The cleaning module includes a second upright, a mounting plate, a cleaning scraper, and an auxiliary block. The mounting plate is fixed to the second upright and is arranged parallel to the ceramic diaphragm. A third limiting rod is fixed to the top of the auxiliary block and passes through the mounting plate. A second limiting rod is fixed to one side of the cleaning scraper and passes through the auxiliary block. The second limiting rod is arranged parallel to the ceramic diaphragm.

[0009] The top of the cleaning scraper is provided with an inclined surface that matches the end wall of the mounting plate. The mounting plate presses the cleaning scraper downwards based on the inclined surface to adhere to the ceramic diaphragm. When the mounting plate moves horizontally in the direction of the cleaning scraper scraping mud, it presses the cleaning scraper downwards based on the inclined surface to adhere to the ceramic diaphragm.

[0010] Preferably, the cleaning module further includes a first upright and a swing arm. A support rod is fixedly connected to the side wall of the first upright, and the support rod is arranged parallel to the mounting plate. One end of the swing arm is hinged to the support rod, and the other end abuts against the cleaning scraper. A sliding rod is fixedly connected to the side wall of the second upright, and the sliding rod passes through the first upright. When the mounting plate moves horizontally toward the direction of the cleaning scraper, the swing arm applies resistance to the cleaning scraper.

[0011] Preferably, a third spring is sleeved on the third limiting rod, and the third spring is used to lift the auxiliary block upward; when the mounting plate moves horizontally in the opposite direction to the sludge scraping direction of the cleaning scraper, the third spring lifts the auxiliary block and the cleaning scraper upward to detach from the ceramic diaphragm.

[0012] Preferably, a baffle is fixedly connected to the middle of the centralized cleaning box, and the mounting box overlaps the baffle. A guide plate is fixedly connected to the bottom of the centralized cleaning box, and a filter plate is fixedly connected to the guide plate. A circulation pipe is connected to one side of the bottom of the centralized cleaning box, and a water outlet pipe is connected to one side of the top. When the cleaning module cleans the ceramic membrane, the wastewater generated flows through both sides of the mounting box to the filter plate at the bottom of the centralized cleaning box, and after filtration, it is circulated into the water outlet pipe to rinse the surface of the ceramic membrane to be cleaned.

[0013] Preferably, the cleaning module further includes a cleaning rod, which is used to guide disordered impurities on the surface of the filter plate to perform a concentrated stacking operation. A connecting rod is fixedly connected to one end of the cleaning rod relative to the second upright, and the connecting rod passes through the second upright.

[0014] A groove is provided on the other side of the centralized cleaning box, through which the cleaning rod passes.

[0015] Preferably, an intermittent slag discharge unit is also provided between the second upright and the cleaning rod. The intermittent slag discharge unit includes a hinged arm and a connecting arm. One end of the hinged arm is hinged to the side wall of the second upright, and the other end is hinged to the middle of the connecting arm. A short rod is fixed to the second upright relative to the cleaning rod. A fixed axis is fixed to the side wall of the short rod relative to the connecting arm. An oblong groove is provided at the end of the connecting arm, and the oblong groove slides with the fixed axis on the second upright. A second spring is sleeved on the connecting rod, and the second spring is used to drive the cleaning rod to reset.

[0016] When the second upright slides to the two ends of the chute, the connecting arm contacts the edge of the chute and is squeezed, causing the oval groove at the end of the connecting arm to slide relative to the fixed axis. At the same time, based on the axial displacement of the cleaning rod due to the squeezing at the end of the connecting arm, when the second connecting rod slides away from the end edge of the chute, the second spring drives the cleaning rod to reset.

[0017] Preferably, the mounting box is rotatably connected to symmetrically arranged rotating clamping arms, which are located at the inner corner of the mounting box; the side wall of the mounting box is provided with a relief groove corresponding to the rotating clamping arms. When the ceramic diaphragm is inserted into the mounting box from the outside to the inside, the edge of the ceramic diaphragm squeezes the rotating clamping arms, causing the rotating clamping arms to rotate from the outside to the inside and press against the ceramic diaphragm.

[0018] Preferably, the mounting box has a movable groove adjacent to the clearance groove, and an H-shaped rod is radially slidably connected in the movable groove. A first spring is fixed between the H-shaped rod and the side wall of the movable groove. A locking block is fixed to the H-shaped rod via a first limiting rod, and the first limiting rod passes through the H-shaped rod. When the rotating clamping arm rotates from the outside to the inside, the end of the rotating clamping arm presses against the locking block, causing the locking block and the H-shaped rod to slide in the movable groove. When the rotating clamping arm passes the locking block, the locking block is driven to reset by the first spring, thus blocking the reset of the rotating clamping arm.

[0019] Preferably, a clamping rod is connected through the side wall of the mounting box, and the clamping rod slides on the side wall of the mounting box under the pressure of the rotating clamping arm when the rotating clamping arm rotates from the outside to the inside, and the ceramic diaphragm is compressed based on the clamping rod.

[0020] Preferably, a plurality of equally spaced parallel partitions are fixedly connected to the bearing plate, and the ceramic diaphragm is supported on the partitions.

[0021] The beneficial effects of this invention are as follows:

[0022] 1. The flat ceramic membrane surface treatment device of the present invention, through the cooperation of the inclined surface of the mounting plate and the cleaning scraper, converts the horizontal driving force into the downward adhesion force of the cleaning scraper, squeezing the cleaning scraper to move obliquely downward until its blade edge is tightly attached to the surface of the ceramic membrane to be cleaned. It can automatically compensate for the unevenness of the membrane surface, ensure effective contact between the cleaning scraper and the surface of each ceramic membrane to be cleaned, eliminate the height difference caused by the fixed installation of the scraper, solve the problem of cleaning dead corners or membrane damage caused by height differences in the prior art, and make the concentrated cleaning effect of ceramic membranes more uniform and safe.

[0023] 2. The flat ceramic membrane surface treatment device of the present invention releases elastic force through a third spring fitted on a third limiting rod, lifting the auxiliary block upward. This, in turn, causes the cleaning scraper to move upward via the second limiting rod, detaching it from the ceramic membrane surface. A swing arm is then slowly reset, ensuring that the swing arm does not contact the cleaned surface of the ceramic membrane during the scraper's reset process. This achieves automatic reset and lifting of the cleaning scraper, and avoids friction between the scraper and the cleaned surface of the ceramic membrane during the return stroke, preventing secondary contamination and ineffective wear, thus improving equipment lifespan and cleaning efficiency.

Detailed Implementation

[0036] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0037] like Figures 1 to 6 , Figure 8 As shown in the figure, a flat ceramic film surface treatment device according to an embodiment of the present invention includes a centralized cleaning box 1 and an installation box 2 installed in the centralized cleaning box 1; a support plate 3 is fixedly connected in the installation box 2, and the support plate 3 is used to support multiple ceramic films 4 arranged in parallel at equal intervals.

[0038] It also includes a cleaning module 5, which is inserted into the centralized cleaning box 1 and is used to clean the surface of the ceramic diaphragm 4 to be cleaned. The cleaning module 5 includes a second upright 52, a mounting plate 55, a cleaning scraper 57, and an auxiliary block 58. The mounting plate 55 is fixed to the second upright 52 and is arranged parallel to the ceramic diaphragm 4. A third limiting rod 581 is fixed to the top of the auxiliary block 58 and passes through the mounting plate 55. A second limiting rod 571 is fixed to one side of the cleaning scraper 57 and passes through the auxiliary block 58. The second limiting rod 571 is arranged parallel to the ceramic diaphragm 4.

[0039] The top of the cleaning scraper 57 is provided with an inclined surface that matches the end wall of the mounting plate 55. The mounting plate 55 presses the cleaning scraper 57 downwards based on the inclined surface to adhere to the ceramic diaphragm 4. When the mounting plate 55 moves horizontally toward the direction of scraping mud by the cleaning scraper 57, it presses the cleaning scraper 57 downwards based on the inclined surface to adhere to the ceramic diaphragm 4.

[0040] In existing technologies, offline centralized cleaning is more thorough and efficient for occasions involving regular overhauls, severe pollution, or batch maintenance. However, existing centralized cleaning devices still have many drawbacks, including the difficulty of adapting to the surface height differences of multi-layer membranes caused by cumulative installation errors and unevenness, which can easily lead to uneven contact between the scraper and the membrane, resulting in incomplete cleaning or scratching of the membrane surface.

[0041] Based on the above, in one embodiment of the present invention, multiple ceramic diaphragms 4 to be cleaned are first placed parallel to each other at equal intervals on a support plate 3 inside the mounting box 2. The support plate 3 temporarily supports the ceramic diaphragms 4, ensuring that the surface of the ceramic diaphragms 4 to be cleaned faces upwards. This is to ensure that the surface of the ceramic diaphragms 4 to be cleaned is opposite to the cleaning module, so that after the cleaning module is activated, the surface of the ceramic diaphragms 4 can be scraped by a scraper, causing the sludge and impurities adhering to the surface of the ceramic diaphragms 4 to detach from the ceramic diaphragms 4. Subsequently, the ceramic diaphragms 4 are placed in a container... The mounting box 2 of the ceramic diaphragm 4 is placed on the centralized cleaning box 1. The cleaning module 5 is pushed or driven so that its second upright 52 is radially inserted into the centralized cleaning box 1. It should be noted that after the cleaning module 5 is sent into the centralized cleaning box 1, it is necessary to ensure that the second upright 52 and the cleaning scraper 57 are at the edge of the fixed ceramic diaphragm 4, and that the cleaning scraper 57 is aligned with the surface of the ceramic diaphragm 4 to be cleaned. This allows the second upright 52 and the cleaning scraper 57 to slide from one edge of the ceramic diaphragm 4 to the other edge, thus enabling the cleaning of the ceramic diaphragm 4. The surface is thoroughly cleaned; in the subsequent scraping process, based on the external electric actuator, the mounting plate 55 is driven to move horizontally in the scraping direction (e.g., from right to left). Since the inclined surface at the top of the cleaning scraper 57 contacts the inclined surface of the end wall of the mounting plate 55, the movement of the mounting plate 55 will generate a vertical component force through the inclined surface cooperation, squeezing the cleaning scraper 57 to move obliquely downward until its blade edge is tightly attached to the surface to be cleaned of the ceramic diaphragm 4; it should be noted that when the vertical component force is applied to the cleaning scraper 57, the cleaning scraper 57 and the ceramic diaphragm 4 are used to achieve the desired cleaning effect. The friction of the surface to be cleaned provides the cleaning scraper 57 with a resistance opposite to the scraping direction. Thus, after the drive mounting plate 55 is displaced, a vertical component force can be effectively generated based on the inclined surface, which acts on the cleaning scraper 57, causing the cleaning scraper 57 to move obliquely downward and its cutting edge to be tightly attached to the surface to be cleaned of the ceramic diaphragm 4. After the cutting edge of the cleaning scraper 57 is tightly attached to the surface to be cleaned of the ceramic diaphragm 4, the mounting plate 55 continues to move horizontally, and the cleaning scraper 57 scrapes and cleans the surface to be cleaned of the ceramic diaphragm 4 in a tightly attached state.

[0042] Based on the above, in this embodiment, by cooperating with the inclined surfaces of the mounting plate 55 and the cleaning scraper 57, the horizontal driving force is converted into the downward adhesion force of the cleaning scraper 57, which can automatically compensate for the unevenness of the diaphragm surface, ensure effective contact between the cleaning scraper 57 and the surface to be cleaned of each ceramic diaphragm 4, eliminate the height difference caused by the fixed installation of the scraper, solve the problem of cleaning dead corners or diaphragm damage caused by height differences in the prior art, and make the concentrated cleaning effect of the ceramic diaphragm 4 more uniform and safe.

[0043] like Figures 1 to 6 , Figure 8 As shown, the cleaning module 5 also includes a first upright 51 and a swing arm 54. A support rod 511 is fixedly connected to the side wall of the first upright 51. The support rod 511 is arranged parallel to the mounting plate 55. One end of the swing arm 54 is hinged to the support rod 511, and the other end abuts against the cleaning scraper 57. A sliding rod 53 is fixedly connected to the side wall of the second upright 52, and the sliding rod 53 passes through the first upright 51. When the mounting plate 55 moves horizontally toward the scraping direction of the cleaning scraper 57, the swing arm 54 applies resistance to the cleaning scraper 57.

[0044] When driving the mounting plate 55 to clean the surface of the ceramic diaphragm 4 along the scraping direction, it is necessary to drive the cleaning scraper 57 to move obliquely downward based on the inclined surface cooperation between the mounting plate 55 and the cleaning scraper 57, so as to achieve effective contact between the cleaning scraper 57 and the surface of the ceramic diaphragm 4 to be cleaned, thereby effectively cleaning the surface thoroughly. In this embodiment, when the mounting plate 55 moves to the left (towards...) Figure 2 As shown, in the initial state, when the cleaning scraper 57 is positioned at the far right of the ceramic diaphragm 4, the second upright 52, which is fixed to it, moves toward the first upright 51 via the slide rod 53. The swing arm 54, hinged to the support rod 511, under the action of the fourth spring (not shown in the figure, ensuring that the angle between the swing arm 54 and the support rod 511 is acute when no force is applied), has its right end abutting against the cleaning scraper 57, thereby applying a rightward resistance to the cleaning scraper 57. This compensates for the insufficient friction between the cleaning scraper 57 and the surface to be cleaned. Based on this, it is ensured that when the mounting plate 55 moves to the left, the cleaning scraper 57 can move obliquely downward and stick to the surface to be cleaned. Based on this resistance, the downward adhesion force generated by the oblique surface of the mounting plate 55 and the cleaning scraper 57 works together to make the cleaning scraper 57 maintain a more stable posture during the working stroke, preventing the scraper from jumping or tilting when encountering resistance, further ensuring the smoothness and effectiveness of the scraping.

[0045] It should be noted that after the cleaning scraper 57 has completely cleaned the surface of the ceramic diaphragm 4, theoretically, since the cleaning scraper 57 has moved to the leftmost side of the ceramic diaphragm 4, the swing arm 54 should be parallel to the support rod 511. At the same time, to prevent the cleaning scraper 57 from still sticking to the cleaned surface of the ceramic diaphragm 4 and contaminating the ceramic diaphragm 4 during the resetting process, in this embodiment, the swing arm 54 does not contact the cleaning scraper 57 during the resetting process. It is foreseeable that damping is provided between the swing arm 54 and the support rod 511 so that the resetting speed of the swing arm 54 is lower than the displacement speed of the cleaning scraper 57. As the cleaning scraper 57 is resetting with the mounting plate 55, the swing arm 54 slowly resets without contacting the cleaning scraper 57. Therefore, when the mounting plate 55 drives the cleaning scraper 57 to reset, since the cleaning scraper 57 is no longer subject to resistance and the displacement direction of the mounting plate 55 is opposite to the scraping direction, the cleaning scraper 57 is no longer sticking to the cleaned surface of the ceramic diaphragm 4.

[0046] like Figures 1 to 6 , Figure 8 As shown, a third spring 582 is sleeved on the third limiting rod 581, and the third spring 582 is used to lift the auxiliary block 58 upward; when the mounting plate 55 moves horizontally in the opposite direction to the sludge scraping direction of the cleaning scraper 57, the third spring 582 lifts the auxiliary block 58 and the cleaning scraper 57 upward to disengage from the ceramic diaphragm 4.

[0047] During the resetting process of the cleaning scraper 57 driven by the mounting plate 55, in order to avoid contaminating the cleaned surface of the ceramic diaphragm 4 with the cleaning scraper 57, when the scraping is completed and the mounting plate 55 moves back to the right (opposite to the scraping direction), the downward pressure on the inclined surface of the cleaning scraper 57 disappears. At this time, the third spring 582 on the third limit rod 581 releases its elastic force, lifting the auxiliary block 58 upward. This, in turn, drives the cleaning scraper 57 upward through the second limit rod 571, causing it to detach from the surface of the ceramic diaphragm 4. At the same time, as the swing arm 54 slowly resets, it does not contact the cleaning scraper 57 during the resetting process, thus achieving no contact between the cleaning scraper 57 and the cleaned surface of the ceramic diaphragm 4 during the resetting process. Based on the above, the automatic resetting and lifting of the cleaning scraper 57 is achieved, and friction between the cleaning scraper 57 and the cleaned surface of the ceramic diaphragm 4 is avoided during the return stroke, preventing secondary contamination and ineffective wear, and improving equipment life and cleaning efficiency.

[0048] like Figures 1 to 6 , Figure 9As shown, a baffle 12 is fixedly connected to the middle of the centralized cleaning box 1, and the mounting box 2 overlaps on the baffle 12. A guide plate 14 is fixedly connected to the bottom of the centralized cleaning box 1, and a filter plate 15 is fixedly connected to the guide plate 14. A circulation pipe 16 is connected to one side of the bottom of the centralized cleaning box 1, and a water outlet pipe 13 is connected to one side of the top. When the cleaning module 5 cleans the ceramic membrane 4, the wastewater generated flows through both sides of the mounting box 2 to the filter plate 15 at the bottom of the centralized cleaning box 1, and after filtration, it is circulated into the water outlet pipe 13 to rinse the surface of the ceramic membrane 4 to be cleaned.

[0049] In the centralized cleaning system, the cleaning process includes scraping the surface of the ceramic diaphragm 4 to be cleaned. In addition to the aforementioned sludge scraping step, the surface of the ceramic diaphragm 4 to be cleaned also needs to be rinsed to soften impurities, making it easier for the cleaning scraper 57 to remove sludge as it passes by. After the ceramic diaphragm 4 is cleaned, the cleaned surface is rinsed to ensure that the ceramic diaphragm 4 is clean. In this embodiment, a chemical solution is prepared for rinsing the surface of the ceramic diaphragm 4 to be cleaned. During the sludge scraping process, the chemical solution is used to rinse the surface of the ceramic diaphragm 4 to be cleaned, softening impurities and facilitating the thorough removal of sludge. The sludge generated during scraping mixes with the rinsing water to form wastewater, which flows down from both sides of the mounting box 2 and is guided by the guide plate 14 to the filter plate 15 at the bottom of the centralized cleaning box 1. Wastewater undergoes solid-liquid separation through filter plate 15; solid impurities are retained, and the preliminarily purified liquid remains at the bottom of the centralized cleaning box 1; the filtered liquid is extracted through circulation pipe 16 by an external pump (not shown in the figure) and pumped back into the outlet water pipe 13 to rinse the uncleaned ceramic membrane 4. After the ceramic membrane 4 is cleaned, it is rinsed through another clean water pipe, and the resulting wastewater also flows into the bottom of the centralized cleaning box 1, mixes with the chemical water, and is used to soften and rinse the uncleaned ceramic membrane 4. Based on the above, the cleaning medium is recycled, saving water and chemicals, reflecting the design concept of energy saving and environmental protection; at the same time, the wastewater collection and rinsing functions are integrated, simplifying the system structure.

[0050] In addition to the circulation pipe 16 and the water outlet pipe 13, the centralized cleaning box 1 should also include a clean water pipe, which can be arranged in parallel with the water outlet pipe 13 and connected to an external water tank (not shown).

[0051] like Figures 1 to 6 , Figure 8 As shown, the cleaning module 5 also includes a cleaning rod 56, which is used to guide disordered impurities on the surface of the filter plate 15 to perform a concentrated stacking operation. A connecting rod 563 is fixedly connected to one end of the cleaning rod 56 relative to the second upright 52, and the connecting rod 563 passes through the second upright 52.

[0052] A groove 11 is provided on the other side of the centralized cleaning box 1, and the cleaning rod 56 passes through the groove 11.

[0053] In theory, the centralized cleaning device should operate continuously to clean a large number of contaminated ceramic membrane sheets 4. Therefore, during the centralized cleaning process, the filter plate 15 will continuously perform solid-liquid separation on the wastewater, resulting in the accumulation of a large number of disordered particulate impurities on the filter plate 15, affecting the efficiency of the continuous solid-liquid separation of the filter plate 15. Based on the above, in this embodiment, the cleaning rod 56 is arranged above the filter plate 15. When the second upright rod 52 moves the entire cleaning module 5 left and right, the cleaning rod 56 moves in conjunction. The cleaning rod 56 can scrape or disturb the impurities deposited on the surface of the filter plate 15, prevent the filter holes from clogging, maintain the permeability of the filter plate 15, and ensure the continuous and efficient operation of the wastewater circulation system. In addition, the cooperation between the cleaning rod 56 and the slide 11 can also provide additional support for the cleaning module 5, making the displacement process of the cleaning module 5 more stable.

[0054] like Figures 1 to 6 , Figure 8 As shown, an intermittent slag discharge unit is also provided between the second upright 52 and the cleaning rod 56. The intermittent slag discharge unit includes a hinged arm 562 and a connecting arm 561. One end of the hinged arm 562 is hinged to the side wall of the second upright 52, and the other end is hinged to the middle of the connecting arm 561. A short rod is fixed to the second upright 52 relative to the cleaning rod 56. A fixed shaft is fixed to the side wall of the short rod relative to the connecting arm 561. An oblong groove is provided at the end of the connecting arm 561, and the oblong groove slides in cooperation with the fixed shaft on the second upright 52. A second spring 564 is sleeved on the connecting rod 563, and the second spring 564 is used to drive the cleaning rod 56 to reset.

[0055] When the second upright 52 slides to the two ends of the slide groove 11, the connecting arm 561 contacts the edge of the slide groove 11 and is squeezed, causing the oval groove at the end of the connecting arm 561 to slide relative to the fixed axis. At the same time, based on the axial displacement of the cleaning rod 56 due to the compression at the end of the connecting arm 561, when the second connecting rod 563 slides away from the end edge of the slide groove 11, the second spring 564 drives the cleaning rod 56 to reset.

[0056] Since impurities on the surface of the filter plate 15 need to be scraped off by the cleaning rod 56, the particulate impurities are moved from their disordered distribution on the filter plate 15 to a concentrated distribution on both sides of the filter plate 15, reducing clogging of the filter pores and maintaining the effective filtration area of ​​the filter plate 15 during continuous operation. However, when the cleaning rod 56 cleans the surface of the filter plate 15, impurities tend to adhere to the cleaning rod 56, leading to a decrease in cleaning efficiency. In this embodiment, when the cleaning rod 56 moves to the left and right ends of the slide groove 11, the end of the connecting arm 561 contacts and is squeezed against the end edge of the slide groove 11, causing the hinge arm 562 fixed to the second upright 52 to rotate accordingly and guide the connecting arm 561 to move. This squeezing forces the connecting arm 561 to move. The end of the cylindrical groove slides relative to the fixed axis on the short rod, thereby pushing the cleaning rod 56 to make a sudden displacement along the axial direction (e.g., towards the water outlet pipe 13). The resulting vibration can shake off the impurities on the cleaning rod 56. When the second upright rod 52 moves away from the end of the sliding groove 11, the compression is released, and the second spring 564 drives the cleaning rod 56 to reset. Based on the above, fixed-point, intermittent automatic heavy-duty cleaning is realized, including cleaning the disordered particulate impurities on the filter plate 15 and cleaning the body of the cleaning rod 56. In addition, the above-mentioned pure mechanical structure for automatic heavy-duty cleaning cleverly transforms the main stroke motion of the cleaning module 5 into a cleaning action for the filter screen, which can effectively solve the deep technical problem of filter screen clogging without additional power.

[0057] like Figures 1 to 6 , Figure 10 As shown, the mounting box 2 is rotatably connected to symmetrically arranged rotating clamping arms 23, which are located at the inner corner of the mounting box 2. The mounting box 2 has a relief groove 21 corresponding to the rotating clamping arms 23 on its side wall. When the ceramic diaphragm 4 is inserted into the mounting box 2 from the outside to the inside, the edge of the ceramic diaphragm 4 presses against the rotating clamping arms 23, causing the rotating clamping arms 23 to rotate from the outside to the inside and press against the ceramic diaphragm 4.

[0058] When the mounting plate 55 moves the cleaning scraper 57 from one side of the ceramic diaphragm 4 to the other to clean the surface of the ceramic diaphragm 4, it is necessary to ensure that the ceramic diaphragm 4 is fixed in place. Otherwise, when the cleaning scraper 57 is in close contact with the ceramic diaphragm 4 and moves, it may cause the ceramic diaphragm 4 to shift, thus failing and making it impossible to effectively clean the surface of the ceramic diaphragm 4. Based on the above, in this embodiment, when the ceramic diaphragm 4 is placed on the support plate 3, it cannot be guaranteed that the ceramic diaphragm 4 is fixed securely. Therefore, when installing the ceramic diaphragm 4, the support plate 3 is first fixed in the mounting box 2. Next, the ceramic diaphragm 4 is inserted from the open side of the mounting box 2. As the ceramic diaphragm 4 is inserted deeper, the edge of the ceramic diaphragm 4 will squeeze the rotating clamping arm 23, causing it to rotate around the axis from the outside to the inside, thereby clamping the ceramic diaphragm 4 from both sides. Based on the above, in this embodiment, the ceramic diaphragm 4 is fixed by controlling the displacement of the ceramic diaphragm 4 toward the rotating clamping arm 23 and by the edge of the ceramic diaphragm 4 squeezing the rotating clamping arm 23. This provides a fast and automatic clamping mechanism, which automatically completes the fixing during the insertion of the diaphragm, eliminating the tedious steps of manually tightening screws and greatly improving the efficiency of installation and disassembly. It is suitable for centralized cleaning scenarios where diaphragms are frequently replaced.

[0059] It is worth noting that in this embodiment, the rotating clamping arm 23 is configured as an L-shaped structure, including a long arm and a short arm. In the initial state, the long arm passes through the relief groove 21 and is located outside the mounting box 2, while the short arm is located inside the mounting box 2. When the ceramic diaphragm 4 moves toward the rotating clamping arm 23, the edge of the ceramic diaphragm 4 squeezes the short arm of the rotating clamping arm 23, and based on the lever principle, the long arm passes through the relief groove 21 and turns to the inside of the mounting box 2, and presses against the edge of the ceramic diaphragm 4.

[0060] like Figures 1 to 6 , Figure 10 As shown, the mounting box 2 has a movable groove 22 adjacent to the clearance groove 21. An H-shaped rod 24 is radially slidably connected in the movable groove 22. A first spring 25 is fixed between the H-shaped rod 24 and the side wall of the movable groove 22. A locking block 26 is fixed to the H-shaped rod 24 via a first limiting rod 261, which passes through the H-shaped rod 24. When the rotating clamping arm 23 rotates from the outside to the inside, the end of the rotating clamping arm 23 presses against the locking block 26, causing the locking block 26 and the H-shaped rod 24 to slide in the movable groove 22. When the rotating clamping arm 23 passes the locking block 26, the first spring 25 drives the locking block 26 to reset, thus blocking the reset of the rotating clamping arm 23.

[0061] It is worth noting that in its initial state, the long arm of the aforementioned rotating clamping arm 23 passes through the clearance groove 21 and is located outside the mounting box 2. Therefore, a torsion spring should be installed on the shaft of the rotating clamping arm 23 to enable the torsion arm to reset when no force is applied. Based on this, when the rotating clamping arm 23 is squeezed inward by the ceramic diaphragm 4, its end will press against the inclined surface of the locking block 26, causing the H-shaped rod 24 to compress the first spring 25 and slide into the movable groove 22. When the rotating clamping arm 23 passes the highest point of the locking block 26, the first spring 25 pushes the H-shaped rod 24 and the locking block 26 to reset. The vertical surface of the locking block 26 blocks the rebound path of the rotating clamping arm 23. Based on this, a mechanical one-way locking mechanism is formed, which allows the clamping arm to easily rotate inward to clamp, but prevents it from rebounding outward to release, ensuring the self-locking and reliability of the clamping, and preventing the diaphragm from loosening due to vibration during the cleaning process.

[0062] like Figures 1 to 6 , Figure 10 As shown, a clamping rod 27 is connected through the side wall of the mounting box 2. When the rotating clamping arm 23 rotates from the outside to the inside, the clamping rod 27 is squeezed by the rotating clamping arm 23 and slides on the side wall of the mounting box 2, and the ceramic diaphragm 4 is squeezed based on the clamping rod 27.

[0063] When the rotating clamping arm 23 rotates inward, its arm body will squeeze the clamping rod 27, forcing the clamping rod 27 to slide inward into the mounting box 2, thereby pressing the edge of the ceramic diaphragm 4 from the side, changing the contact area between the rotating clamping arm 23 and the edge of the ceramic diaphragm 4. Based on the arrangement of the clamping rod 27, it is not necessary to set a corresponding number of rotating clamping arms 23 for the number of ceramic diaphragms 4. At the same time, it is only necessary to set a fifth spring between the clamping rod 27 and the mounting box 2 to realize the reset of the rotating clamping arm 23 and the clamping rod 27 when no force is applied. It is not necessary to set a torsion spring separately for the rotating clamping arm 23, making the fixing mechanism structure of the ceramic diaphragm 4 simpler.

[0064] like Figure 7 As shown, a plurality of equally spaced parallel partitions 31 are fixedly connected to the bearing plate 3, and the ceramic diaphragm 4 is supported on the partitions 31.

[0065] The ceramic diaphragm 4 is directly supported on the partition plate 31. The partition plate 31 ensures the equidistant and parallel relationship between the multiple diaphragms, providing a basic guarantee for the smooth insertion of the cleaning module 5 and uniform cleaning.

[0066] Working principle: First, multiple ceramic diaphragms 4 to be cleaned are placed parallel to each other at equal intervals on the support plate 3 inside the mounting box 2. The support plate 3 temporarily supports the ceramic diaphragms 4, ensuring that the surface of the ceramic diaphragms 4 to be cleaned faces upwards. This is to ensure that the surface of the ceramic diaphragms 4 to be cleaned is opposite to the cleaning module, so that after the cleaning module is activated, the scraper can scrape the surface of the ceramic diaphragms 4 to remove the dirt and impurities adhering to the surface of the ceramic diaphragms 4. Then, the mounting box 2 containing the ceramic diaphragms 4 is placed on the collection... On the central cleaning box 1, push or drive the cleaning module 5 so that its second upright 52 is radially inserted into the central cleaning box 1. It is important to note that after the cleaning module 5 is inserted into the central cleaning box 1, ensure that the second upright 52 and the cleaning scraper 57 are positioned at the edge of the fixed ceramic diaphragm 4, and that the cleaning scraper 57 is aligned with the surface of the ceramic diaphragm 4 to be cleaned. This ensures that when the second upright 52 and the cleaning scraper 57 slide from one edge of the ceramic diaphragm 4 to the other, the surface of the ceramic diaphragm 4 can be thoroughly cleaned. In subsequent scraping... During the cleaning process, the mounting plate 55 is driven to move horizontally in the scraping direction (e.g., from right to left) based on the external electric actuator. Since the inclined surface at the top of the cleaning scraper 57 contacts the inclined surface of the end wall of the mounting plate 55, the movement of the mounting plate 55 generates a vertical component force through the inclined surface cooperation, squeezing the cleaning scraper 57 to move obliquely downward until its blade edge is tightly attached to the surface to be cleaned of the ceramic diaphragm 4. It should be noted that when the vertical separation action is applied to the cleaning scraper 57, the cleaning is achieved by the friction between the cleaning scraper 57 and the surface to be cleaned of the ceramic diaphragm 4. The cleaning scraper 57 has a resistance opposite to the scraping direction, so that after the drive mounting plate 55 is displaced, it can effectively generate a vertical component force based on the inclined surface, which acts on the cleaning scraper 57, causing the cleaning scraper 57 to move obliquely downward and its cutting edge to be tightly pressed against the surface to be cleaned of the ceramic diaphragm 4; when the cutting edge of the cleaning scraper 57 is tightly pressed against the surface to be cleaned of the ceramic diaphragm 4, the mounting plate 55 continues to move horizontally, and the cleaning scraper 57 scrapes and cleans the surface to be cleaned of the ceramic diaphragm 4 in a tightly pressed state; when the mounting plate 55 moves to the left (towards... Figure 2As shown, in the initial state, when the cleaning scraper 57 is positioned at the far right of the ceramic diaphragm 4, the second upright 52, which is fixed to it, moves toward the first upright 51 via the slide rod 53. The swing arm 54, hinged to the support rod 511, under the action of the fourth spring (not shown in the figure, ensuring that the angle between the swing arm 54 and the support rod 511 is acute when no force is applied), has its right end abutting against the cleaning scraper 57, thereby applying a rightward resistance to the cleaning scraper 57. This compensates for the insufficient friction between the cleaning scraper 57 and the surface to be cleaned. Based on this, it is ensured that when the mounting plate 55 moves to the left, the cleaning scraper 57 can move obliquely downward and stick to the surface to be cleaned. Based on this resistance, the downward adhesion force generated by the oblique surface of the mounting plate 55 and the cleaning scraper 57 works together to make the cleaning scraper 57 maintain a more stable posture during the working stroke, preventing the scraper from jumping or tilting when encountering resistance, further ensuring the smoothness and effectiveness of the scraping.

[0067] When the scraping is complete and the mounting plate 55 moves back to the right (opposite to the scraping direction), the downward pressure on the inclined surface of the cleaning scraper 57 disappears. At this time, the third spring 582 on the third limit rod 581 releases its elastic force, lifting the auxiliary block 58 upward. This, in turn, drives the cleaning scraper 57 upward through the second limit rod 571, causing it to detach from the surface of the ceramic diaphragm 4. Simultaneously, as the swing arm 54 slowly resets, it does not contact the cleaned surface of the ceramic diaphragm 4 during the reset process, thus achieving no contact between the cleaning scraper 57 and the cleaned surface of the ceramic diaphragm 4 during the reset process. Based on the above, automatic reset and lifting of the cleaning scraper 57 are achieved, and friction between the cleaning scraper 57 and the cleaned surface of the ceramic diaphragm 4 is avoided during the return stroke, preventing secondary pollution and ineffective wear, and improving equipment life and cleaning efficiency. The cleaning solution is prepared for rinsing the surface of the ceramic diaphragm 4 to be cleaned during the scraping process. The cleaning process softens impurities, facilitating the thorough removal of sludge. The sludge generated during cleaning mixes with the rinsing water to form wastewater, which flows down from both sides of the mounting box 2 and is guided by the guide plate 14 to the filter plate 15 at the bottom of the centralized cleaning box 1. The wastewater undergoes solid-liquid separation through the filter plate 15; solid impurities are retained, and the preliminarily purified liquid remains at the bottom of the centralized cleaning box 1. The filtered liquid is then pumped out through the circulation pipe 16 by an external pump (not shown in the figure) and pumped back into the outlet pipe 13 to rinse the uncleaned ceramic membrane 4. After cleaning, the ceramic membrane 4 is rinsed again through a separate clean water pipe, and the resulting wastewater also flows into the bottom of the centralized cleaning box 1, mixes with the chemical water, and is used to soften and rinse the uncleaned ceramic membrane 4. Based on the above, the cleaning medium is recycled, saving water and chemicals, reflecting the energy-saving and environmentally friendly design concept. At the same time, the wastewater collection and rinsing functions are integrated, simplifying the system structure.

[0068] When the cleaning rod 56 moves to the left and right ends of the slide 11, the end of the connecting arm 561 contacts and is squeezed with the end edge of the slide 11, causing the hinge arm 562 fixed on the second upright 52 to rotate and guide the connecting arm 561 to move. This squeezing forces the connecting arm 561 to move, and the oval groove at its end slides relative to the fixed axis on the short rod, thereby pushing the cleaning rod 56 to make a sudden displacement along the axial direction (e.g., towards the water outlet pipe 13). The resulting vibration can shake off the impurities on the cleaning rod 56. When the second upright 52 moves away from the end of the slide 11, the squeezing is released, and the second spring 564 drives the cleaning rod 56 to reset. Based on the above, fixed-point, intermittent automatic heavy-duty cleaning is realized, including cleaning the disorderly distributed particulate impurities on the filter plate 15 and the cleaning rod 56 body. In addition, the above-mentioned pure mechanical structure for automatic heavy-duty cleaning cleverly transforms the main stroke motion of the cleaning module 5 into a cleaning action for the filter screen, effectively solving the deep technical problem of filter screen clogging without additional power.
