Description

Technical Field

[0001] This invention relates to the field of ceramic plate cleaning equipment technology, and more specifically, to a ceramic filter and ceramic plate cleaning device. Background Technology

[0002] Ceramic filters are commonly used solid-liquid separation equipment in mineral processing plants for filtration of concentrate products. The equipment consists of a ceramic filter body and ceramic filter plates. The material and permeability of the ceramic filter plates determine the filtration effect on the concentrate product. To ensure the concentrate moisture content remains within a reasonable range, it is essential to regularly remove fine solid particles and other impurities from the gaps in the ceramic filter plates to maintain their permeability. Currently, ceramic filters are widely used in mineral processing plants; however, the fragility of ceramic filter plates and the small gaps in the filter plates necessitate the use of specialized cleaning equipment.

[0003] The current popular technique involves fixing the ceramic filter plate in a cleaning tank and then rinsing it with diluted nitric acid solution or a high-temperature solution. However, this approach has the following problems: during the cleaning process, due to the extremely small gaps on the surface of the ceramic filter plate, the cleaning solution does not reach the surface sufficiently. Simply soaking in acid or rinsing at high temperatures is insufficient to effectively remove impurities from the surface of the ceramic filter plate, and the cleaning effect on the fine solid particles on and inside the filter plate is poor. Summary of the Invention

[0004] The purpose of this invention is to provide a ceramic plate cleaning device for a ceramic filter, which addresses the shortcomings of existing technologies and solves the problems mentioned in the background.

[0005] The technical solution of this invention is implemented as follows:

[0006] This invention provides a ceramic plate cleaning device for a ceramic filter, including a mounting frame installed on the ceramic filter. The mounting frame has two cleaning chambers respectively placed on both sides of the ceramic plate. Each cleaning chamber has a cleaning cavity, and each cleaning cavity has a conveyor belt. The cleaning cavity has a drive assembly for driving the conveyor belt to move in a circular motion. The outer wall of the conveyor belt has multiple cleaning rollers. The cleaning cavity has a pressing mechanism for forcing a portion of the conveyor belt to approach the ceramic plate. The outer side of the cleaning chamber has a discharge port communicating with the cleaning cavity. The discharge port has a cleaning mechanism for cleaning the cleaning rollers that pass through the discharge port in sequence.

[0007] In some technical solutions of the present invention, an installation groove is provided on the outer wall of the conveyor belt along the conveying direction of the conveyor belt, and a plurality of mounting seats corresponding one-to-one with the cleaning rollers are provided in the installation groove, and a rotating shaft that is rotatably connected to the cleaning rollers is provided on the mounting seat.

[0008] In some technical solutions of the present invention, the cleaning roller includes a plurality of first cleaning elements arranged along the circumference of the cleaning roller, and a second cleaning element is provided between any two adjacent first cleaning elements.

[0009] In some technical solutions of the present invention, two damping springs are provided at both ends of the rotating shaft, and the free ends of the damping springs are connected to the inner wall of the mounting base.

[0010] In some technical solutions of the present invention, a conductive slide rail is provided in the cleaning chamber along the transmission direction of the conveyor belt, and a conductive spring is provided on the mounting base. The conductive spring is electrically connected to the second cleaning component, and a bent section is provided on the free end of the conductive spring to abut against the conductive slide rail.

[0011] In some technical solutions of the present invention, the pressing mechanism includes a fixed seat installed in the cleaning chamber, two pressure rods slidably disposed on the outer side wall of the fixed seat, a pressure plate slidably connected to the pressure rods in the cleaning chamber, the pressure plate abutting against the inner wall of the conveyor belt, a limiting spring abutting against the two pressure rods on the fixed seat, a first magnetic pole piece installed on the fixed seat, and a second magnetic pole piece connected to the limiting spring on the fixed seat.

[0012] In some technical solutions of the present invention, the cleaning mechanism includes a sink trough opened in a fixed base, a guide ring passing through the sink trough, a retaining seat on the side of the guide ring away from the fixed base, a buffer spring connected to the retaining seat in the sink trough, a push-out roller rotatably installed in the retaining seat, and a discharge pipe at the discharge outlet, which is connected to an external negative pressure device.

[0013] In some technical solutions of the present invention, a plurality of through slots are provided on the side wall of the conveyor belt along its circumference, and any one through slot is located between any two adjacent cleaning rollers. A plurality of suction cups adapted to the through slots are provided on the side wall of the pressure plate along its extension direction, and the suction cups are connected to the discharge pipe.

[0014] In some technical solutions of the present invention, the driving assembly includes two transmission wheels rotatably disposed in the cleaning chamber, a transmission belt sleeved on the two transmission wheels, and a drive motor connected to the transmission wheels is provided on the outer wall of the cleaning chamber.

[0015] In some technical solutions of the present invention, two levers are inclinedly provided inside the outlet, and the angle between the two levers after their reverse extensions intersect is an acute angle.

[0016] Compared with the prior art, the present invention has at least the following advantages or beneficial effects:

[0017] When the conveyor belt makes a near-circular motion, the cleaning roller can contact the outer wall of the ceramic plate to be cleaned and clean the same location on the outer wall of the ceramic plate multiple times, improving the cleaning effect.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0028] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0029] Example

[0030] Please refer to Figures 1-7 As shown.

[0031] This invention provides a ceramic plate cleaning device for a ceramic filter, such as... Figure 1 , Figure 2As shown, the system includes a mounting frame 2 that is rotatably mounted on a ceramic filter via a shaft. The mounting frame 2 has a frame-like structure and two cleaning chambers 1 positioned on either side of a ceramic plate 3. Each cleaning chamber 1 is rectangular and covers most of the ceramic plate 3. The outer wall of each cleaning chamber 1 has a bracket bolted to the mounting frame 2, facilitating adjustment of the relative distance between the cleaning chamber 1 and the ceramic plate 3. This allows for better contact between the cleaning roller 13 installed in the cleaning chamber 1 and the ceramic plate 3, improving the adaptability of the structure and the cleaning effect on the micropores of the ceramic plate 3. Furthermore, the top outer edge of the cleaning chamber 1 can scrape off filtered metal deposits adhering to the ceramic plate 3. The cleaning chamber 1 can also be positioned at the original scraper location of an existing ceramic filter, facilitating improvements to the existing filter by pre-cleaning excess metal deposits and reducing the difficulty of subsequent cleaning. Each cleaning chamber 1 contains a rectangular cleaning cavity 16, and each cleaning cavity 16 contains a conveyor belt 7 of appropriate width. A drive assembly drives the conveyor belt 7 to perform circular motion. Multiple cleaning rollers 13 are mounted on the outer wall of the conveyor belt 7, equidistantly arranged along the conveying direction of the conveyor belt 7. Thus, when the conveyor belt 7 performs a near-circular motion, the cleaning rollers 13 can contact the outer wall of the ceramic plate 3 to be cleaned, performing multiple cleanings on the same location on the outer wall of the ceramic plate 3, improving the cleaning effect. A pressing mechanism is provided inside the cleaning chamber 16 to force a portion of the conveyor belt 7 closer to the ceramic plate 3. This structure allows the cleaning rollers 13 on the ceramic plate 3 to make closer contact with the outer wall of the ceramic plate 3 to be cleaned. An outlet 5 communicating with the cleaning chamber 16 is opened on the outer side of the cleaning chamber 1. When the cleaning rollers 13 that have already contacted the outer wall of the ceramic plate 3 pass through the outlet 5 sequentially under the drive of the conveyor belt 7, a cleaning mechanism located at the outlet 5 can clean the cleaning rollers 13 that have passed through the outlet 5 sequentially, ensuring that the cleaning rollers 13 remain relatively clean after passing through the cleaning mechanism, thereby improving the cleaning efficiency for other areas of the ceramic plate.

[0032] In some technical solutions of the present invention, an installation groove is provided on the outer wall of the conveyor belt 7 along the circumference of the conveyor belt 7. The cross-sectional area of ​​the installation groove is rectangular. Multiple mounting seats 25 corresponding to the cleaning roller 13 are provided in the installation groove. The mounting seats 25 are detachably connected to the inner wall of the installation groove by means of rivets, which facilitates later maintenance. The mounting seats 25 are provided with a rotating shaft 26 that is rotatably connected to the cleaning roller 13. The above structure can ensure that while the cleaning roller 13 is in contact with the ceramic plate 3 in the installation groove, the static friction generated when the cleaning roller 13 is in contact with the ceramic plate 3 is forced by the circumferential motion of the conveyor belt 7, so that the cleaning roller 13 makes a passive circumferential motion in the installation groove, thereby changing the cleaning surface of the cleaning roller 13 and keeping the cleaning surface in contact with the ceramic plate 3 relatively clean at all times.

[0033] In some technical solutions of the present invention, the cleaning roller 13 includes a plurality of first cleaning elements arranged circumferentially along the cleaning roller 13. The first cleaning elements are hard plastic brush strips, which clean the stubborn deposits on the surface of the ceramic plate when the cleaning roller 13 contacts the ceramic plate, and play a scraping and friction role. A second cleaning element is provided between any two adjacent first cleaning elements. The second cleaning element is a flexible rubber brush strip that can be embedded in the fine holes in the ceramic plate 3 to clean the fine solid particles inside and improve the cleaning effect on the structure in the above-mentioned structural area.

[0034] In some technical solutions of the present invention, the rotating shaft 26 is slidably disposed in a groove provided on the mounting base 25, so that the cleaning roller 13 connected to the rotating shaft 26 has room to move in the mounting groove, and will not make hard contact with the ceramic plate 3 when in contact, thus preventing the structure from damaging the ceramic plate 3. Two damping springs 24 are provided at both ends of the rotating shaft 26, and the free ends of the damping springs 24 are connected to the inner wall of the mounting base 25, which can ensure that after the cleaning roller 13 is subjected to external force in the mounting groove and its initial position changes, it can return to the initial position again, so that the cleaning roller 13 is always in contact with the surface of the ceramic plate 3.

[0035] In some technical solutions of the present invention, a conductive slide rail 15 is provided inside the cleaning chamber 16 along the transmission direction of the conveyor belt 7; the conductive slide rail 15 includes two vertical sections and one arc section, the arc section is located between the two vertical sections and the above structure is integrally formed, one of the vertical sections is located at the opening of the cleaning chamber 16 and has the same length as the vertical section of the conveyor belt 7; the other vertical section is located at the bottom of the cleaning chamber 16 and is approximately equal to half the length of the vertical section of the conveyor belt 7, with its end located at the outlet; each mounting base 25 is provided with a conductive spring piece 23, the conductive spring piece 23 is L-shaped, the conductive spring piece 23 is electrically connected to the second cleaning component through a conductive slip ring, and the free end of the conductive spring piece 23 is provided with a conductive spring piece 23. The bent section of the electric slide rail 15 abuts against the conductive spring 23, and the bent section can make a certain range of elastic movement relative to the conductive spring 23. When the cleaning roller 13 located on the conveyor belt 7 is driven by the transmission belt 7 to the opening of the cleaning chamber 16 through the above structure, the conductive spring 23 connected to the cleaning roller 13 overlaps on the conductive slide rail 15. The second cleaning brush located on the cleaning roller 13 is in an energized state, so that the second cleaning component generates magnetism, and the fine solid particles located inside the ceramic plate 3 are attracted out of the ceramic plate 3 by magnetic attraction. Furthermore, the above structure and the ceramic plate structure can be used together with the backwashing equipment to clean the interior, thereby improving the cleaning effect of this structure on the fine pore structure of the ceramic plate 3.

[0036] In some technical solutions of the present invention, the pressing mechanism includes a fixed seat 10 installed in the cleaning chamber 16. The fixed seat 10 is fixed to the inner wall of the cleaning chamber 16 by bolts. Two pressure rods 9 are slidably provided on the outer wall of the fixed seat 10 via a sliding sleeve. The two pressure rods 9 are welded to the outer wall of the sliding sleeve. A pressure plate 12 is provided in the cleaning chamber 16 and slidably connected to the pressure rods 9. A wedge-shaped groove is opened on the pressure plate 12 along its extension direction. Two wedge-shaped guide blocks, respectively connected to the pressure rods 9, are slidably provided in the wedge-shaped groove. The pressure plate 12 abuts against the inner wall of the conveyor belt 7. A limiting spring 11 that abuts against the two pressure rods 9 is sleeved on the fixed seat 10. A first The magnetic pole piece 21 and the fixed base 10 are fitted with a second magnetic pole piece 22 connected to the limiting spring 11. The first magnetic pole piece 21 and the second magnetic pole piece 22 are two magnetic poles that repel each other. The repulsive force generated by the first magnetic pole piece 21 on the second magnetic pole piece 22 is greater than the pushing force generated by the limiting spring 11 on the second magnetic pole piece 22. The above structure prevents the cleaning roller 13 in the conveyor belt 7 from making hard contact with the ceramic plate 3 when the pressure plate 12 pushes the conveyor belt 7 towards the ceramic plate 3, effectively preventing damage to the ceramic plate 3. It also applies a downward pushing force to the cleaning tube 13 located in the conveyor belt 7 to ensure a tighter contact between the cleaning roller 13 and the ceramic plate.

[0037] In some technical solutions of the present invention, the cleaning mechanism includes a sink trough opened in the fixed seat 10, a guide ring 20 passing through the sink trough, a retaining seat 17 on the side of the guide ring 20 away from the fixed seat 10, a buffer spring 18 connected to the retaining seat 17 in the sink trough, a push-out roller 28 rotatably provided in the retaining seat 17, and a discharge pipe 6 provided at the discharge outlet 5, which is connected to an external negative pressure device. The above structure allows the conveyor belt 7, which moves to the outlet 5, to be lifted by the clamping seat 17 using the push force applied by the buffer spring 18, and placed inside the outlet along with the cleaning roller 13 located there. When the cleaning roller 13 moves to the outlet 5, the conductive spring 23 connected to the cleaning roller 13 changes from being overlapped on the conductive slide rail 15 to being disconnected from the conductive slide rail 15. The second cleaning brush located on the cleaning roller 13 is de-energized, so that the second cleaning component no longer generates magnetism. The fine solid particles adsorbed on the second cleaning component are extracted from the cleaning chamber 1 from the outlet 5 by the negative pressure device, completing one complete cleaning cycle.

[0038] In some technical solutions of the present invention, a plurality of through grooves 27 are provided on the side wall of the conveyor belt 7 along its circumference. Any one of the through grooves 27 is located between any two adjacent cleaning rollers 13. A plurality of suction cups 19 adapted to the through grooves 27 are provided on the side wall of the pressure plate 12 along its extension direction. The suction cups 19 are connected to the discharge pipe 6. The suction cups 19 in the above structure are embedded in the pressure plate 12. The working principle of the suction cups 19 is as follows: when the negative pressure equipment is started, the suction force generated by it can reach the suction cups 19 directly through the pipe and adsorb the fine solid particles cleaned off the ceramic plate 3 by the cleaning rollers 13 until they are discharged from the cleaning chamber 1 through the discharge pipe 6.

[0039] In some technical solutions of this invention, the driving assembly includes two transmission wheels 8 rotatably disposed within the cleaning chamber 16, a transmission belt 7 sleeved on the two transmission wheels 8, and a drive motor connected to the transmission wheels 8 is provided on the outer wall of the cleaning chamber 1. This structure ensures that the transmission belt 7 performs continuous circular motion within the cleaning chamber 16, ensuring continuous cleaning of the ceramic plate.

[0040] In some technical solutions of the present invention, two levers 14 are inclinedly arranged inside the discharge port 5, with the free ends of the two levers 14 facing the discharge pipe 6, and the included angle between the reverse extension lines of the two levers 14 is an acute angle. The above structure effectively prevents the backflow of fine solid particles adsorbed from the second cleaning element into the cleaning chamber 16.

[0041] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
