Description

Technical Field

[0001] The present invention belongs to the technical field of ceramic membrane cleaning, and particularly relates to an automatic cleaning device for removing surface pollutants of a ceramic membrane with a self-cleaning function. Background Art

[0002] In the application of ceramic membranes, the removal of surface pollutants is crucial. Traditional methods mostly rely on manual labor, manually scrubbing with brushes and chemical agents, which is inefficient and labor-intensive. Although there are simple spray cleaning devices, they are helpless against stubborn pollutants. Although ultrasonic cleaning has been applied, due to the difficulty in accurately controlling parameters, it is easy to damage the ceramic membrane. In the face of the demand for efficient, accurate, and non-destructive cleaning, it is urgent to develop an automatic cleaning device for removing surface pollutants of ceramic membranes.

[0003] Currently, a Chinese invention with the publication number: CN119035131A discloses an integrated ceramic membrane cleaning device, including a cleaning device body. Inside the cleaning device body, there are a drying chamber, a spraying chamber, a scraper removal chamber, and an immersion chamber. Multiple fixed legs are provided at the bottom of the cleaning device body. In this invention, when the standard cylinder two moves upward, it drives the bottom of the ceramic membrane to contact the bottom of the scraper two. At this time, the external driving device drives the winding rod to rotate clockwise through the gear, and then winds the ceramic membrane during the rotation process. During this process, the ceramic membrane wound around the outer part of the driving roller one passes through the cleaning liquid in the first cleaning tank and the second cleaning tank inside the cleaning device body in sequence to soften the ceramic on the surface of the ceramic membrane. During the conveying process of the ceramic membrane, the ceramic on the surface of the ceramic membrane is scraped and cleaned by the first scraper and the second scraper, and the silicone oil on the surface of the ceramic membrane is removed by the de-silicone oil cleaning liquid in the third cleaning tank.

[0004] The existing automatic cleaning device for removing surface pollutants of a ceramic membrane with a self-cleaning function has the following disadvantages when in use:

[0005] 1. When removing surface pollutants of the ceramic membrane, due to the lack of a structure adapted to the shape and size of the ceramic membrane, it is unable to adapt to ceramic membranes of different sizes, reducing the flexibility in removing surface pollutants of ceramic membranes of different sizes.

[0006] 2. When removing surface pollutants of the ceramic membrane, due to the lack of a self-cleaning structure after circulating cleaning of the ceramic membrane pollutants, it is unable to self-clean after circulating cleaning of the ceramic membrane pollutants, reducing the stability during long-term cleaning of the ceramic membrane pollutants. Summary of the Invention

[0007] The purpose of the present invention is directed to an existing automatic cleaning device for removing surface pollutants of a ceramic membrane with a self-cleaning function, and its advantages are:

[0008] 1. When removing contaminants from the surface of a ceramic membrane, due to having a structure adapted to the shape and size of the ceramic membrane, it can adapt to ceramic membranes of different sizes, improving the flexibility in removing surface contaminants from ceramic membranes of different sizes.

[0009] 2. When removing contaminants from the surface of a ceramic membrane, due to having a self-cleaning structure after cyclic cleaning of the ceramic membrane contaminants, it can self-clean after cyclic cleaning of the ceramic membrane contaminants, improving the stability during long-term cleaning of the ceramic membrane contaminants.

[0010] The above technical objectives of the present invention are achieved through the following technical solutions: An automatic device for removing surface contaminants of a ceramic membrane with self-cleaning function, including a cleaning cylinder, a wetting mechanism, and a cleaning mechanism. A maintenance and installation plate is fixedly connected to the inner side of the front side of the cleaning cylinder. Opening and closing hydraulic rods are fixedly connected to both sides of the cleaning cylinder. An installation cover is fixedly connected to the output end of the front side of the opening and closing hydraulic rod. The wetting mechanism is fixedly connected to the rear side of the installation cover. A servo motor is fixedly connected to the rear side of the inner side of the cleaning cylinder. An adjustment turntable is fixedly connected to the front side of the servo motor. An adjustment hydraulic rod is fixedly connected to the surface of the adjustment turntable. The cleaning mechanism is fixedly connected to the front side of the output end of the adjustment hydraulic rod.

[0011] The wetting mechanism includes a liquid extraction pump, a liquid storage tank, a pressure spray head, a partition ring plate, and a positioning slide rod. The liquid extraction pump is connected to the rear side of the installation cover. The liquid storage tank is connected to the rear side of the liquid extraction pump.

The partition ring plate is fixedly connected to the side of the rear side of the liquid storage tank close to the pressure spray head. The positioning slide rod is fixedly connected to the surface of the liquid storage tank. The output end of the surface of the positioning slide rod is clamped with the front side of the cleaning mechanism.

[0012] The cleaning mechanism includes a circulation pipe, a separation plate, a high-pressure air extraction pump, a spiral scraping plate, and an interception clamping plate. The circulation pipe is clamped to the front side of the output end of the adjustment hydraulic rod. The front side of the circulation pipe is clamped with the rear side of the output end of the positioning slide rod. The separation plate is fixedly connected to the inside of the circulation pipe. The high-pressure air extraction pump is fixedly connected to the side of the separation plate close to the adjustment turntable. The spiral scraping plate is rotatably connected to the side of the inside of the circulation pipe away from the high-pressure air extraction pump. The interception clamping plate is clamped to the side of the circulation pipe close to the spiral scraping plate.

[0013] The spiral scraping plate includes a guiding rotating rod, a drainage plate, and an interception net. The guiding rotating rod is rotatably connected to the side of the inside of the circulation pipe away from the high-pressure air extraction pump. The drainage plate is fixedly connected to the surface of the guiding rotating rod. The interception net is clamped to the inside of the drainage plate. The surface of the drainage plate is in contact with the inside of the interception clamping plate.

[0014] With the above technical solution, by setting up a cleaning cylinder, a maintenance and installation plate, an opening and closing hydraulic rod, an installation cover, a wetting mechanism, a servo motor, an adjustment turntable, an adjustment hydraulic rod, and a cleaning mechanism, the cleaning cylinder can form a sealed space with the maintenance and installation plate. The opening and closing hydraulic rod can cooperate with the installation cover to connect the wetting mechanism with the servo motor and the cleaning mechanism, thereby realizing the limitation of the ceramic membrane. The wetting mechanism can transport a cleaning liquid to the surface of the ceramic membrane for wetting. The servo motor can drive the adjustment turntable to adjust the orientation of the adjustment hydraulic rod. The adjustment hydraulic rod can adjust the distance between the cleaning mechanism and the ceramic membrane in real time to adapt to ceramic membranes of different sizes, so that the adjustment hydraulic rod can drive the cleaning mechanism to rotate, and the cleaning mechanism can rotate around the surface of the ceramic membrane, thereby cleaning the surface of the ceramic membrane. At the same time, the cleaning mechanism can perform cyclic cleaning on its own internal structure.

[0015] The invention is further configured as follows: A sealing plug is fixedly connected to the rear side of the installation cover. A sealing sleeve is sleeved on the surface of the sealing plug, and the surface of the sealing sleeve is clamped with the inner side of the maintenance and installation plate.

[0016] With the above technical solution, by setting up the sealing plug and the sealing sleeve, the sealing plug and the sealing sleeve can further block the connection between the installation cover and the maintenance and installation plate, thereby further increasing the tightness when the installation cover and the maintenance and installation plate are connected.

[0017] The invention is further configured as follows: A reinforcing plate is fixedly connected to the output end on the surface of the positioning slide rod, and the rear side of the reinforcing plate is clamped with the front side of the circulation pipe.

[0018] With the above technical solution, by setting up the reinforcing plate, the connection between the positioning slide rod and the circulation pipe can be further strengthened. Through the plate-shaped structure of the reinforcing plate itself, the connection area between the positioning slide rod and the circulation pipe can be increased, thereby further increasing the stability when the circulation pipe and the positioning slide rod are connected.

[0019] The invention is further configured as follows: A buffer pad is fixedly connected to the rear side of the partition ring plate, and anti-slip patterns are provided on the surface of the buffer pad.

[0021] The invention is further configured as follows: A contact plate is fixedly connected to the front side of the adjustment turntable, and protrusions are provided on the surface of the contact plate.

[0022] By adopting the above technical solution, a contact plate is provided to protect the contact point between the adjusting dial and the ceramic membrane.

[0024] By adopting the above technical solution, by providing a reinforcement plate and a reinforcement rod, the adjustment hydraulic rod is limited by the reinforcement structure formed by the reinforcement plate and the reinforcement rod, which can further increase the structural stability of the adjustment hydraulic rod.

[0025] The present invention is further configured as follows: the output end of the high-pressure air pump is fixedly connected to a collecting nozzle, and the collecting nozzle is configured to be conical.

[0026] By adopting the above technical solution, through the setting of a collecting nozzle, the air extracted by the high-pressure vacuum pump can be further concentrated and guided. Through the conical design of the collecting nozzle itself, the air can be concentrated to the ceramic membrane and sent out, thereby increasing the intensity of the airflow delivery and improving the efficiency of cleaning the ceramic membrane.

[0027] The present invention is further configured as follows: a guide wheel is rotatably connected to the surface of the circulation pipe, and a wheel sleeve is provided on the surface of the guide wheel.

[0028] By adopting the above technical solution, through the provision of a guide wheel and a wheel sleeve, the guide wheel can contact the surface of the ceramic membrane, and guide the movement of the circulation tube on the surface of the ceramic membrane through its own rotation, thereby increasing the stability of the circulation tube when moving. The wheel sleeve is made of soft material, so the wheel sleeve can protect the contact point between the guide wheel and the surface of the ceramic membrane, thereby increasing the stability of the guide wheel when moving on the surface of the ceramic membrane.

[0029] The present invention is further configured as follows: a cleaning plate is fixedly connected to one side of the circulation pipe close to the adjusting turntable, and the cleaning plate is configured to be arc-shaped.

[0030] By adopting the above technical solution, a cleaning plate is set up to scrape off the pollutants on the surface of the ceramic membrane as it moves with the circulation tube. The arc-shaped design makes it elastic and avoids damage caused by rigid contact between the cleaning plate and the surface of the ceramic membrane.

[0031] The present invention is further configured as follows: a filter screen is clamped on the inner side of the interception card plate, the filter screen is configured as an arc surface, and the inner side of the filter screen contacts the surface of the guide plate.

[0032] By adopting the above technical solution, a filter net is set up to intercept pollutants in the air flowing through the interception card, and its own arc surface design can better fit the rotation trajectory of the guide plate, thereby increasing the efficiency of the guide plate in scraping off pollutants on the filter net.

[0035] 2. By setting up a cleaning mechanism, the circulation pipe can cooperate with the separation plate to form a U-shaped airflow conveying channel, so that the high-pressure vacuum pump can draw air from the circulation pipe and the separation plate at one end away from the high-pressure vacuum pump, and draw it out from the high-pressure vacuum pump, so that the pollutants on the surface of the ceramic membrane can be blown away by the high-pressure airflow, and the blown pollutants are drawn into the circulation pipe and sent to the spiral scraper. The spiral scraper can intercept the pollutants flowing through and transport them to the interception card. The interception card can intercept the pollutants flowing through, and drive the rotation of the interception net around the guide rod through the guide plate to scrape off the pollutants on the interception card, so that the pollutants remain on each interception net to avoid blockage and form a self-cleaning effect.

[0050] As Figure 4As shown, a reinforcing plate 12 is fixedly connected to the output end on the surface of the positioning slide bar 55. The rear side of the reinforcing plate 12 is clamped with the front side of the circulation pipe 91. By providing the reinforcing plate 12, the connection between the positioning slide bar 55 and the circulation pipe 91 can be further strengthened. Through the plate-like structure of the reinforcing plate 12 itself, the area when the positioning slide bar 55 is connected to the circulation pipe 91 can be increased, thereby further increasing the stability when the circulation pipe 91 is connected to the positioning slide bar 55.

[0051] As Figure 4 shown, a buffer pad 13 is fixedly connected to the rear side of the partition ring plate 54. Anti-slip patterns are provided on the surface of the buffer pad 13. By providing the buffer pad 13, it can cooperate with the partition ring plate 54.

[0055] Embodiment 2:

[0056] Refer toFigures 7-9 , an automatic cleaning device for surface pollutants of a ceramic membrane with self-cleaning function, including a cleaning mechanism 9. The cleaning mechanism 9 includes a circulation pipe 91, a separation plate 92, a high-pressure air extraction pump 93, a spiral scraper 94 and an interception card plate 95. The circulation pipe 91 is clamped on the front side of the output end of the adjusting hydraulic rod 8, and the front side of the circulation pipe 91 is clamped with the rear side of the output end of the positioning slide rod 55. The separation plate 92 is fixedly connected to the inner side of the circulation pipe 91. The high-pressure air extraction pump 93 is fixedly connected to the side of the separation plate 92 close to the adjusting turntable 7. The spiral scraper 94 is rotatably connected to the side of the inner side of the circulation pipe 91 far from the high-pressure air extraction pump 93. The interception card plate 95 is clamped on the side of the circulation pipe 91 close to the spiral scraper 94; The spiral scraper 94 includes a guiding rotating rod 941, a drainage plate 942 and an interception net 943. The guiding rotating rod 941 is rotatably connected to the side of the inner side of the circulation pipe 91 far from the high-pressure air extraction pump 93. The drainage plate 942 is fixedly connected to the surface of the guiding rotating rod 941. The interception net 943 is clamped inside the drainage plate 942. The surface of the drainage plate 942 is in contact with the inner side of the interception card plate 95. By setting the cleaning mechanism 9, the circulation pipe 91 can cooperate with the separation plate 92 to form a U-shaped air flow conveying channel, which can allow the high-pressure air extraction pump 93 to suck air from one end of the circulation pipe 91 and the separation plate 92 far from the high-pressure air extraction pump 93 and extract it from the high-pressure air extraction pump 93. Thus, it can realize blowing off the pollutants on the surface of the ceramic membrane through high-pressure air flow, and sucking and sending the blown-off pollutants into the spiral scraper 94 through the circulation pipe 91. The spiral scraper 94 can intercept the flowing pollutants and convey them to the interception card plate 95. The interception card plate 95 can intercept the flowing pollutants, and drive the rotation of the interception net 943 around the guiding rotating rod 941 through the drainage plate 942 to scrape off the pollutants on the interception card plate 95, so that the pollutants remain on each interception net 943 to avoid blockage and form a self-cleaning effect.

[0057] As Figure 8 shown, a flow collector nozzle 17 is fixedly connected to the output end of the high-pressure air extraction pump 93. The flow collector nozzle 17 is conical. By setting the flow collector nozzle 17, the air extracted by the high-pressure air extraction pump 93 can be further centrally guided. Through the conical design of the flow collector nozzle 17 itself, the air can be concentrated and sent to the ceramic membrane, so as to increase the intensity of air flow conveying and improve the cleaning efficiency of the ceramic membrane.

[0058] As Figure 8As shown, a guide wheel 18 is rotatably connected to the surface of the circulation pipe 91, and a wheel sleeve 19 is sleeved on the surface of the guide wheel 18. By providing the guide wheel 18 and the wheel sleeve 19, the guide wheel 18 can contact the surface of the ceramic membrane and guide the movement of the circulation pipe 91 on the surface of the ceramic membrane through its own rotation, increasing the stability of the circulation pipe 91 during movement. The wheel sleeve 19 is made of a soft material, so the wheel sleeve 19 can protect the contact area between the guide wheel 18 and the surface of the ceramic membrane, increasing the stability of the guide wheel 18 when moving on the surface of the ceramic membrane.

[0059] As Figure 8 shown, a cleaning plate 20 is fixedly connected to the side of the circulation pipe 91 close to the adjustment turntable 7. The cleaning plate 20 is arc-shaped. By providing the cleaning plate 20, when moving along with the circulation pipe 91, it can scrape off the pollutants on the surface of the ceramic membrane. Through its own arc-shaped design, it can have elasticity and avoid rigid contact with the surface of the ceramic membrane and causing damage.

[0060] As Figure 9 shown, a filter screen 21 is clamped inside the intercepting card plate 95. The filter screen 21 is arc-shaped, and the inner side of the filter screen 21 contacts the surface of the drainage plate 942. By providing the filter screen 21, it can intercept the pollutants in the air flowing through the intercepting card plate 95, and through its own arc-shaped design, it can better fit the rotation trajectory of the drainage plate 942, thereby increasing the efficiency of the drainage plate 942 in scraping off the pollutants on the filter screen 21.

[0061] Brief description of the usage process: First, when it is necessary to clean the pollutants on the surface of the ceramic membrane, the high-pressure air pump 93 will pump the air on the side of the circulation pipe 91 far from the high-pressure air pump 93 into the channel between the circulation pipe 91 and the separation plate 92 on the side far from the high-pressure air pump 93. Then the air will flow through the circulation pipe 91 to the spiral scraping plate 94, and the intercepting net 943 will drive the drainage plate 942 to rotate around the guide rotating rod 941 along with the flowing air, and when rotating, the drainage plate 942 will scrape off the pollutants on the surface of the intercepting card plate 95. After that, the air will carry the pollutants to flow towards the intercepting card plate 95, and then the intercepting card plate 95 will intercept the pollutants in the air and let the filtered air flow towards the high-pressure air pump 93. The high-pressure air pump 93 will pressurize the air and blow it to the surface of the ceramic membrane to blow off the pollutants on the surface of the ceramic membrane, and let the blown-off pollutants enter the circulation pipe 91 again along with the air for filtration to form a cycle. When it is necessary to clean the pollutants in the circulation pipe 91, take out the intercepting card plate 95 from the circulation pipe 91 and replace it with a new intercepting card plate 95, and then replace the intercepting net 943 with a new intercepting net 943.
