Description

Technical Field

[0001] The present application belongs to the technical field of solid-liquid separation equipment, and in particular, relates to a rotary ceramic filter. Background Art

[0002] As a dehydration equipment, ceramic vacuum filter reduces the operation cost, the water content of fly ash, and has the advantages of high working efficiency, high degree of automation, low failure rate, and small maintenance workload. It is generally used for solid-liquid separation and dehydration of sediment, metal ore, etc. However, when the filter currently used is working, the mineral material filtered out of the filter plate will agglomerate on the filter plate, which makes it inconvenient to remove the filtered mineral material from the filter plate.

[0003] The patent with publication number CN217391785U discloses a ceramic filter, including a ceramic filter body, which is installed on a frame, a main motor is installed on one side of the ceramic filter body, the output end of the main motor is connected to an intermediate shaft, a third filter cartridge is installed on the intermediate shaft, the outer side of the third filter cartridge is sequentially provided with a second filter cartridge and a first filter cartridge, and a plurality of filter plates are installed on the outer surface of the first filter cartridge, a chassis connected to the bottom of the ceramic filter body is provided, and a reduction motor is installed at the bottom end of the left outer wall of the chassis, the output end of the reduction motor is connected to a rotating rod, and a scraper plate is connected to the rotating rod.

[0004] The above patent uses a scraper plate to clean the mud on the inner wall of the equipment to prevent the mud from agglomerating, and sets the scraper plate to be detachable to facilitate later maintenance. The scraper plate is installed by a positioning plate and a locking bolt. Although it is easy to disassemble and assemble the scraper plate, due to the bolts, multiple disassembly and assembly or disassembly and assembly after a long interval will cause a problem, that is, thread wear. Once worn, the scraper plate will be unstable when installed again, resulting in shaking when scraping, which ultimately prevents the mud from falling smoothly, causing unnecessary losses, and needs to be improved. Utility Model Content

[0005] The purpose of this application is to provide a rotary ceramic filter that can solve the above problems.

[0006] The purpose of this application is to provide a rotary ceramic filter, comprising:

[0007] The filter body comprises a frame, a plurality of ceramic sheets arranged on the frame, a pressure chamber, a driving motor, a mud tank and a collecting hopper;

[0008] A scraping device, comprising a plurality of scraper groups and a mounting mechanism for mounting the scrapers on a frame;

[0009] Each group of scrapers has two scrapers, and one group of scrapers corresponds to one ceramic sheet. The two scrapers are symmetrically arranged on both sides of the ceramic sheet and are bonded to the ceramic sheet.

[0010] The above-mentioned rotary ceramic filter is adopted, and the ceramic sheet is used as the filter medium. The microporous structure on its surface can effectively intercept solid particles and allow liquid to pass through, thereby achieving solid-liquid separation and ensuring filtering efficiency and stability. Each group of scrapers has two scrapers, which are symmetrically arranged on both sides of the ceramic sheet and fit tightly with the ceramic sheet. This design can ensure that during the rotation process, the scraper can evenly scrape the filter cake on the surface of the ceramic sheet to avoid the accumulation of filter cake and the clogging of the micropores of the ceramic sheet, thereby maintaining the continuous filtering capacity of the filter. The ceramic sheet is driven to rotate by a driving motor, and the scraping device is used to automatically scrape the material, thereby realizing the automatic operation of the filter and reducing the manual operation cost and labor intensity. Multiple ceramic sheets are arranged on the frame, and in conjunction with components such as a mud tank and a collection hopper, the entire filter structure is compact, occupies a small area, and is easy to install and arrange. At the same time, the setting of the mounting mechanism can facilitate the installation and disassembly of the scraper, and then facilitate the replacement and maintenance of the scraper.

[0011] Furthermore, the installation mechanism includes:

[0012] An adjustment structure is arranged on the frame and is used to adjust the distance between each set of scrapers;

[0013] A mounting structure for fixing the scraper;

[0014] The scraper comprises a scraper body and a blade seat. The scraper body is mounted on the blade seat through a mounting structure, and one end of the blade seat away from the scraper body is connected to the adjustment structure.

[0015] By setting the adjustment structure, the user can adjust the spacing between each set of scrapers according to actual needs, so as to adapt to filter cakes of different thicknesses, ensure that the scraper can effectively remove solid residues on the ceramic sheet, and avoid unnecessary damage to the ceramic sheet. It can also optimize the performance of the filter, such as adjusting the scraper spacing to adapt to different filtration speeds or mud concentrations. By setting the mounting structure, the scraper is firmly fixed on the blade holder, ensuring that the scraper can remain stable during rotation and keep a close fit with the ceramic sheet, ensuring that the scraper will not loosen or shift during long-term use, thereby improving the reliability and durability of the filter. The scraper consists of a scraper body and a blade holder. The scraper body contacts the ceramic sheet and is responsible for removing solid residues. The blade holder serves as a bridge connecting the scraper body and the adjustment structure and plays a supporting role.

[0016] Further: the installation structure includes:

[0017] A first groove is provided on the scraper body, a mounting protrusion is provided in the first groove, and a first mounting hole is provided on the mounting protrusion;

[0018] A second groove is arranged on the knife seat, a positioning plate is arranged in the second groove, a threaded hole is arranged on the positioning plate, and a second mounting hole corresponding to the position of the first mounting hole and the threaded hole is also arranged on the knife seat;

[0019] A bolt, the end of which is provided with threads adapted to the threaded hole;

[0020] The bolt passes through the first mounting hole and the second mounting hole in sequence and is connected to the threaded hole. The diameters of the first mounting hole and the second mounting hole are the same and larger than the diameter of the threaded hole.

[0021] By setting up the mounting mechanism, a stable connection between the scraper body and the knife holder can be ensured, and the two can be easily disassembled, repaired and replaced. By setting up the first groove and the second groove, a mounting protrusion is set in the first groove, a positioning plate is set in the second groove, and with the cooperation of the bolt, the connection between the scraper body and the knife holder can be completed. The mounting protrusion is designed in the groove, which increases the contact area of ​​the screw during installation and improves the stability of the connection. During installation, the bolt will pass through the first mounting hole and the second mounting hole in turn and then connect with the threaded hole. When the barrel cover needs to be removed, just loosen the bolt, which is convenient and quick.

[0022] In addition, in the present application, the diameters of the first mounting hole and the second mounting hole are the same and larger than the diameter of the threaded hole. Therefore, the bolt will not come into contact with the inner walls of the first mounting hole and the second mounting hole during installation and disassembly, thereby causing no friction. Moreover, the threaded hole only appears in the positioning plate. Even if the threaded hole is worn, only the positioning plate needs to be replaced, without having to replace the entire blade holder or scraper body, thereby reducing losses.

[0023] Furthermore, a rotating head is provided on the mounting protrusion, the rotating head is threadedly connected to the mounting protrusion, and a limiting through hole adapted to the outer diameter of the bolt is provided on the mounting head.

[0024] By setting the rotating head, the bolt can be prevented from directly contacting the mounting protrusion, and the tightening effect of the bolt can be increased, effectively preventing the bolt from being excessively deep or loose, thereby ensuring that the connection between the scraper body and the blade holder is more firm and stable. At the same time, the setting of the limit through hole can prevent the bolt from shaking during and after installation.

[0025] Furthermore, the installation structure also includes:

[0026] A pressure ring, arranged on the bolt;

[0027] An abutment ring, arranged on the inner wall of the second mounting hole;

[0028] Wherein, an elastic member is also arranged between the pressure ring and the abutment ring, and the elastic member is a spring.

[0029] When installing the cylinder body and the cylinder cover, as the bolts are gradually tightened, the pressure ring and the abutment ring gradually squeeze the elastic part, thereby making the bolt tightening effect better, improving the installation stability between the knife holder and the scraper body, and preventing shaking; and when disassembling between the knife holder and the scraper body, as the bolts are gradually unscrewed, the pressure ring and the abutment ring gradually move away from each other. At this time, the elastic part resets and provides elastic force. The distance between the pressure ring and the abutment ring affected by the elastic force gradually increases. The position of the abutment ring is fixed, so the pressure ring will gradually move away from the abutment ring, thereby providing power for the bolts to be screwed out, thereby improving the disassembly efficiency of the user.

[0030] Furthermore, the regulating structure includes:

[0031] The mounting seat has a cavity inside, and a bidirectional screw rod is arranged in the cavity;

[0032] A slide groove is arranged on one side of the mounting seat and communicated with the cavity;

[0033] The slider group includes a first slider and a second slider stacked and arranged on the bidirectional lead screw;

[0034] A driver, which is arranged on a mounting seat and connected to a bidirectional lead screw;

[0035] Wherein, the first sliding block and the second sliding block are both connected to the tool holder.

[0036] Through the cooperation of the bidirectional screw and the slider group, the first slider and the second slider can move simultaneously and symmetrically, so as to realize the precise adjustment of the spacing between each set of scrapers, ensuring that the scraper can maintain balance during the adjustment process, and avoiding the deflection or damage of the scraper due to uneven adjustment. The cavity set inside the mounting seat provides stable support for the bidirectional screw. At the same time, the cooperation of the slide groove and the slider group ensures the stability and reliability of the scraper during movement, so that the scraper can maintain a stable motion trajectory during the scraping process, avoiding damage caused by vibration or impact. The design of this adjustment structure enables the rotary ceramic filter to adapt to filter cakes of different thicknesses and properties. By adjusting the scraper spacing, the filter can cope with various complex filtering scenarios, improving the applicability and flexibility of the equipment.

[0037] The beneficial effects of this application are:

[0038] 1. By setting up the installation mechanism, the installation and disassembly of the scraper can be facilitated, thereby facilitating the replacement and maintenance of the scraper;

[0039] 2. The diameters of the first mounting hole and the second mounting hole are the same and larger than the diameter of the threaded hole. Therefore, the bolt will not contact the inner wall of the first mounting hole and the second mounting hole during installation and removal, thereby not causing friction. Moreover, the threaded hole only appears in the positioning plate. Even if the threaded hole is worn, only the positioning plate needs to be replaced, without replacing the entire blade seat or scraper body, thereby reducing losses.

[0040] 3. Through the cooperation of the bidirectional screw and the slider group, the first slider and the second slider can move simultaneously and symmetrically, so as to realize the precise adjustment of the spacing between each group of scrapers, ensure that the scraper can maintain balance during the adjustment process, avoid the deflection or damage of the scraper caused by uneven adjustment, and cope with various complex filtration scenarios, thus improving the applicability and flexibility of the equipment.

[0063] In the embodiment of the present application, by setting the adjustment structure 300, the user can adjust the spacing between each group of scrapers according to actual needs, so as to adapt to filter cakes of different thicknesses, ensure that the scraper can effectively remove the solid residues on the ceramic sheet 120, and avoid unnecessary damage to the ceramic sheet 120. It can also optimize the performance of the filter, such as adjusting the scraper spacing to adapt to different filtering speeds or mud concentrations. By setting the mounting structure 400, it is used to firmly fix the scraper on the knife seat 210, ensure that the scraper can remain stable during the rotation process, and keep a close fit with the ceramic sheet 120, ensuring that the scraper will not loosen or deviate during long-term use, thereby improving the reliability and durability of the filter. The scraper includes a scraper body 200 and a knife seat 210. The scraper body 200 contacts the ceramic sheet 120 and is responsible for removing solid residues. The knife seat 210 serves as a bridge connecting the scraper body 200 and the adjustment structure 300, and plays a supporting role.

[0064] Embodiment 3:

[0065] An embodiment of the present application provides a rotary ceramic filter. In addition to the above-mentioned technical features, the rotary ceramic filter of the embodiment of the present application also includes the following technical features.

[0066] like Figures 3 to 6 As shown, the mounting structure 400 includes:

[0067] A first groove 410 is provided on the scraper body, a mounting protrusion 411 is provided in the first groove 410, and a first mounting hole 412 is provided through the mounting protrusion 411;

[0068] The second groove 420 is provided on the knife seat 210. A positioning plate 421 is provided in the second groove 420. A threaded hole 422 is provided on the positioning plate 421. The knife seat 210 is also provided with a second mounting hole 423 corresponding to the first mounting hole 412 and the threaded hole 422.

[0069] A bolt 430, the end of which is provided with a thread adapted to the threaded hole 422;

[0070] The bolt 430 passes through the first mounting hole 412 and the second mounting hole 423 in sequence and is connected to the threaded hole 422 . The diameters of the first mounting hole 412 and the second mounting hole 423 are the same and larger than the diameter of the threaded hole 422 .

[0071] In the embodiment of the present application, by setting up the mounting mechanism, the stable connection between the scraper body and the knife holder 210 can be ensured, and the disassembly between the two can be facilitated, and the maintenance and replacement can be facilitated. By setting up the first groove 410 and the second groove 420, setting the mounting protrusion 411 in the first groove 410, setting the positioning plate 421 in the second groove 420, and with the cooperation of the bolt 430, the connection between the scraper body 200 and the knife holder 210 can be completed.

During installation, the bolt 430 will pass through the first mounting hole 412 and the second mounting hole 423 in turn and then connect with the threaded hole 422. When the barrel cover needs to be removed, it is only necessary to loosen the bolt 430, which is convenient and quick.

[0072] In addition, in the present application, the diameters of the first mounting hole 412 and the second mounting hole 423 are the same and larger than the diameter of the threaded hole 422. Therefore, the bolt 430 will not come into contact with the inner walls of the first mounting hole 412 and the second mounting hole 423 during the installation and disassembly process, thereby causing no friction. Moreover, the threaded hole 422 only appears in the positioning plate. Even if the threaded hole 422 is worn, only the positioning plate 421 needs to be replaced, without having to replace the entire blade holder 210 or the scraper body 200, thereby reducing losses.

[0073] A rotating head 440 is disposed on the mounting protrusion 411 . The rotating head 440 is threadedly connected to the mounting protrusion 411 , and a limiting through hole 441 matching the outer diameter of the bolt 430 is disposed on the mounting head.

[0074] By providing the rotating head 440, the bolt 430 can be prevented from directly contacting the mounting protrusion 411, and the tightening effect of the bolt 430 can be increased, effectively preventing the bolt 430 from being excessively penetrated or loosened, thereby ensuring a more firm and stable connection between the scraper body 200 and the blade holder 210. At the same time, the provision of the limiting through hole 441 can prevent the bolt 430 from shaking during and after installation.

[0080] An elastic member 470 is disposed between the pressure ring 450 and the abutting ring 460 , and the elastic member 470 is a spring.

[0081] In the embodiment of the present application, when the cylinder body and the cylinder cover are installed, as the bolt 430 is gradually tightened, the pressure ring 450 and the abutment ring 460 gradually squeeze the elastic member 470, so that the fastening effect of the bolt 430 is better, the installation stability between the knife seat 210 and the scraper body 200 is improved, and the shaking is prevented; and when disassembling between the knife seat 210 and the scraper body 200, as the bolt 430 is gradually screwed out, the pressure ring 450 and the abutment ring 460 gradually move away from each other. At this time, the elastic member 470 resets and provides elastic force, and the distance between the pressure ring 450 and the abutment ring 460 affected by the elastic force gradually increases. The position of the pressure ring 450 and the abutment ring 460 is fixed, so the pressure ring 450 will gradually move away from the abutment ring 460, thereby providing power for the screwing out of the bolt 430, thereby improving the disassembly efficiency of the user.
