Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, and in particular to a sealing component installation structure for a ceramic membrane. Background Technology

[0002] The existing ceramic membrane sealing component installation structure mainly includes: a mounting plate with multiple mounting holes, the diameter of which is larger than the outer diameter of the ceramic membrane tube, allowing the ceramic membrane tube to be inserted into the mounting holes of the mounting plate, forming a gap between them. A sealing ring is installed in the gap to seal it. In addition, it includes a movable pressure plate fixedly connected to the mounting plate. The surface of the movable pressure plate has a through groove for the end of the ceramic membrane tube to extend out. The movable pressure plate is fastened to the mounting plate with bolts. Tightening the bolts causes the movable pressure plate to compress the sealing ring, causing the sealing ring to deform at the gap between the mounting hole and the ceramic membrane tube, thus sealing the gap.

[0003] The advantage of the above technical solution is that it is quick to install. After placing the ceramic membrane tube and the sealing ring in the mounting hole of the mounting plate, the movable pressure plate is tightened with bolts to fix it to the mounting plate and squeeze the sealing ring, so that a batch of ceramic membrane tubes can be installed at one time. However, the disadvantage is that it is not possible to install and disassemble individual ceramic membrane tubes. When it is necessary to disassemble a ceramic membrane tube, it can only be disassembled as a whole, so there is an inconvenience in operation. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a sealing component installation structure for ceramic membranes, so as to solve the technical problem that the existing sealing component installation structures for ceramic membrane tubes are not convenient for individual installation and disassembly of individual ceramic membrane tubes.

[0005] To achieve the above objectives, this utility model provides a sealing component mounting structure for a ceramic membrane, comprising:

[0006] A mounting plate is provided on the inner wall of the filter cartridge, and the mounting plate has multiple mounting holes for mounting ceramic membrane tubes;

[0007] A movable pressure plate and a fastening assembly for locking the movable pressure plate onto the mounting plate;

[0008] A first sealing ring is fitted onto the surface of the ceramic membrane tube and between the mounting plate and the movable pressure plate;

[0009] Multiple clamping sleeves are detachably connected to the movable pressure plate. Each clamping sleeve has a through hole through which one end of the ceramic membrane tube passes. The clamping sleeve is located above the first sealing ring. By operating the fastening assembly, the movable pressure plate can drive the clamping sleeve to press down on the first sealing ring so that it deforms.

[0010] As a preferred embodiment of this utility model, the inner diameter of the first sealing ring is interference-fitted with the outer diameter of the ceramic membrane tube, the minimum diameter of the outer diameter of the first sealing ring is smaller than the diameter of the mounting hole, and the maximum diameter of the outer diameter of the first sealing ring is larger than the diameter of the mounting hole, so that the first sealing ring can be partially embedded in the gap between the mounting hole and the ceramic membrane tube.

[0011] As a preferred embodiment of this utility model, the fastening assembly includes a bolt, and the upper end of the movable pressure plate is provided with a countersunk hole for placing the bolt. The shank of the bolt passes through the countersunk hole and is threadedly connected to a first threaded groove opened on the mounting plate.

[0012] As a preferred embodiment of this utility model, the lower end of the movable pressure plate is provided with a positioning pin, which engages with a positioning sleeve located on the upper end of the mounting plate.

[0013] As a preferred technical solution of this utility model, the outer surface of the clamping sleeve is provided with an external thread, and the surface of the movable pressure plate is provided with a second thread groove that matches the external thread. By rotating the clamping sleeve, it can make it move vertically relative to the movable pressure plate. The inner diameter of the second thread groove is greater than the maximum outer diameter of the first sealing ring.

[0014] As a preferred embodiment of this utility model, the outer side of the mounting plate is seamlessly connected to the inner wall of the filter cylinder, the movable pressure plate matches the cross-sectional shape of the inner wall of the filter cylinder, and a sealing ring is provided on the outer side of the movable pressure plate to prevent fluid from seeping between the outer side of the movable pressure plate and the inner wall of the filter cylinder.

[0015] As a preferred embodiment of this utility model, the upper end of the clamping sleeve forms an end cap larger than the diameter of the second threaded groove, and a second sealing ring is sleeved on the outside of the clamping sleeve. The second sealing ring can be pressed together by the lower end face of the end cap and the upper end face of the movable pressure plate.

[0016] As a preferred embodiment of this utility model, the end cap has a polygonal structure.

[0017] The beneficial effects of this utility model are as follows: By detachably clamping the sleeves on the movable pressure plate, the movable pressure plate can drive all the clamping sleeves to squeeze the first sealing ring. When it is necessary to remove the ceramic membrane tubes on the mounting plate individually, simply remove the clamping sleeve of the ceramic membrane tube from the movable pressure plate to remove the corresponding ceramic membrane tube. When it is necessary to remove all the ceramic membrane tubes on the mounting plate, simply remove the fastening components and separate the movable pressure plate from the mounting plate to remove all the ceramic membrane tubes from the mounting plate. Therefore, it is possible to flexibly install and remove the ceramic membrane tubes. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0025] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0026] like Figure 1 and Figure 2 As shown, a sealing component installation structure for a ceramic membrane includes: an installation plate 1 disposed on the inner wall of the filter cartridge, the installation plate 1 having a plurality of installation holes 2 for installing ceramic membrane tubes 3; a movable pressure plate 5 and a fastening assembly for locking the movable pressure plate 5 onto the installation plate 1; a first sealing ring 4 sleeved on the surface of the ceramic membrane tube 3 and between the installation plate 1 and the movable pressure plate 5; and a plurality of clamping sleeves 7 detachably connected to the movable pressure plate 5, the clamping sleeves 7 having through holes 8 for one end of the ceramic membrane tube 3 to pass through, the clamping sleeves 7 being located above the first sealing ring 4, and by operating the fastening assembly, the movable pressure plate 5 can drive the clamping sleeves 7 to press down on the first sealing ring 4 to deform it;

[0027] The above technical solution allows for the batch disassembly of all ceramic membrane tubes 3 on the mounting plate 1 or the disassembly of a single ceramic membrane tube 3. During installation, the first sealing ring 4 is fitted onto the ceramic membrane tube 3, and the ceramic membrane tube 3 is vertically inserted into the mounting hole 2 of the mounting plate 1, ensuring that the lower end face of the first sealing ring 4 is in contact with the upper end face of the mounting plate 1. The movable pressure plate 5 is placed on the mounting plate 1, ensuring that the upper end of the ceramic membrane tube 3 passes through the through hole 8 of the clamping sleeve 7. The fastening assembly is used to move the movable pressure plate 5 downward, thereby moving the clamping sleeve 7 connected to the movable pressure plate 5 downward synchronously. The lower end face of the clamping sleeve 7 and the upper end face of the mounting plate 1 are used to jointly squeeze the first sealing ring 4, causing the first sealing ring 4 to deform and lock the ceramic membrane tube 3, while sealing the gap between the ceramic membrane tube 3 and the mounting hole 2, thus completing the installation.

[0028] When it is necessary to remove one of the ceramic membrane tubes 3 on the mounting plate 1, simply remove the clamping sleeve 7 of the ceramic membrane tube 3 from the movable pressure plate 5 to release the restriction on the first sealing ring 4, so that the first sealing ring 4 together with the ceramic membrane tube 3 connected to it can be removed from the movable pressure plate 5.

[0029] When it is necessary to remove all the ceramic membrane tubes 3 on the mounting plate 1, simply remove the fastening components to release the restriction on the first sealing ring 4, thereby allowing all the ceramic membrane tubes 3 to be removed from the mounting plate 1, thus enabling flexible installation and removal.

[0030] like Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, the outer side of the clamping sleeve 7 is provided with an external thread, and the surface of the movable pressure plate 5 is provided with a second thread groove 6 that matches the external thread. By rotating the clamping sleeve 7, it can make it move vertically relative to the movable pressure plate 5. The inner diameter of the second thread groove 6 is greater than the maximum outer diameter of the first sealing ring 4.

[0031] The above technical solution allows the clamping sleeve 7 to be connected to the movable pressure plate 5 via a threaded connection. By rotating the clamping sleeve 7 in the first direction, its external thread engages with the second threaded groove 6 of the movable pressure plate 5, thus screwing the clamping sleeve 7 into the second threaded groove 6 of the movable pressure plate 5. When it is necessary to disassemble the clamping sleeve 7, simply rotate the clamping sleeve 7 in the second direction opposite to the first direction to remove the clamping sleeve 7 from the second threaded groove 6. Since the inner diameter of the second threaded groove 6 is larger than the maximum outer diameter of the first sealing ring 4, the first sealing ring 4 along with the ceramic membrane tube 3 can be pulled out from the second threaded groove 6, facilitating disassembly.

[0032] like Figure 3 As shown, in this embodiment, the inner diameter of the first sealing ring 4 is interference-fitted with the outer diameter of the ceramic membrane tube 3. The minimum diameter of the outer diameter of the first sealing ring 4 is smaller than the diameter of the mounting hole 2, and the maximum diameter of the outer diameter of the first sealing ring 4 is larger than the diameter of the mounting hole 2, so that the first sealing ring 4 can be partially embedded in the gap between the mounting hole 2 and the ceramic membrane tube 3.

[0033] The above technical solution can better seal the gap between the mounting hole 2 and the ceramic membrane tube 3. By adopting the first sealing ring 4 with a wedge structure, one end of the first sealing ring 4 can be embedded in the gap to prevent it from falling off. At the same time, the upper end of the first sealing ring 4 protrudes from the mounting plate 1 so as to contact the lower end face of the clamping sleeve 7.

[0034] like Figure 2 and Figure 4 As shown, in this embodiment, the fastening assembly includes a bolt 13. The upper end of the movable pressure plate 5 is provided with a countersunk hole 12 for placing the bolt 13. The shank of the bolt 13 passes through the countersunk hole 12 and is threadedly connected to the first threaded groove 14 opened on the mounting plate 1.

[0035] The above technical solution can fix the movable pressure plate 5 to the mounting plate 1 by bolt 13. When in use, after the movable pressure plate 5 is pre-positioned, the bolt 13 is passed through the countersunk hole 12 on the surface of the movable pressure plate 5 and threadedly connected to the first threaded groove 14 on the mounting plate 1. As the bolt 13 is screwed in, the movable pressure plate 5 can be moved down until it reaches the maximum position.

[0036] like Figure 4 As shown, in this embodiment, a positioning pin 10 is provided at the lower end of the movable pressure plate 5, and the positioning pin 10 is engaged with the positioning sleeve 11 located at the upper end of the mounting plate 1.

[0037] The above technical solution can easily position the movable pressure plate 5 on the mounting plate 1, preventing the movable pressure plate 5 from shaking when rotating the bolt 13.

[0038] like Figure 1As shown, in this embodiment, the outer side of the mounting plate 1 is seamlessly connected to the inner wall of the filter cylinder, the movable pressure plate 5 matches the cross-sectional shape of the inner wall of the filter cylinder, and a sealing ring is provided on the outer side of the movable pressure plate 5. The sealing ring is used to prevent fluid from seeping between the outer side of the movable pressure plate 5 and the inner wall of the filter cylinder.

[0039] The above technical solution can improve the sealing between the movable pressure plate 5 and the inner wall of the filter cylinder, preventing fluid from seeping through the gap between them.

[0040] like Figure 3 As shown, in this embodiment, the upper end of the clamping sleeve 7 forms an end cap larger than the diameter of the second threaded groove 6, and a second sealing ring 9 is sleeved on the outside of the clamping sleeve 7. The second sealing ring 9 can be pressed together by the lower end face of the end cap and the upper end face of the movable pressure plate 5. Preferably, the end cap has a polygonal structure to facilitate the rotation of the clamping sleeve 7.

[0041] The above technical solution can further improve the sealing performance of the device. By setting the second sealing ring 9, the second sealing ring 9 can be compressed when the clamping sleeve 7 is turned. The second sealing ring 9 seals the gap between the second threaded groove 6 and the clamping sleeve 7, preventing fluid from seeping in from the gap.

[0042] Working principle:

[0043] During installation, the first sealing ring 4 is fitted onto the ceramic membrane tube 3, and the ceramic membrane tube 3 is vertically inserted into the mounting hole 2 of the mounting plate 1, ensuring that the lower end of the first sealing ring 4 is embedded in the mounting hole 2 of the mounting plate 1. The movable pressure plate 5 is placed on the mounting plate 1, ensuring that the positioning pin 10 is aligned with the positioning sleeve 11. The upper end of the ceramic membrane tube 3 passes through the through hole 8 of the clamping sleeve 7. The bolt 13 is passed through the countersunk hole 12 on the surface of the movable pressure plate 5 and threadedly connected to the first threaded groove 14 on the mounting plate 1. As the bolt 13 is screwed in, the movable pressure plate 5 is moved down, thereby causing the clamping sleeve 7 connected to the movable pressure plate 5 to move down synchronously. The lower end face of the clamping sleeve 7 and the upper end face of the mounting plate 1 are used to squeeze the first sealing ring 4, causing the first sealing ring 4 to deform and lock the ceramic membrane tube 3, while sealing the gap between the ceramic membrane tube 3 and the mounting hole 2, thus completing the installation.

[0044] When it is necessary to disassemble one of the ceramic membrane tubes 3 on the mounting plate 1, simply remove the clamping sleeve 7 of the ceramic membrane tube 3 from the movable pressure plate 5, rotate the clamping sleeve 7 to disengage it from the second threaded groove 6, and the restriction on the first sealing ring 4 can be released. Since the inner diameter of the second threaded groove 6 is larger than the maximum outer diameter of the first sealing ring 4, the first sealing ring 4 together with the ceramic membrane tube 3 can be pulled out from the second threaded groove 6 for easy disassembly.

[0045] When it is necessary to remove all the ceramic membrane tubes 3 on the mounting plate 1, simply remove the bolts 13 to release the restriction on the first sealing ring 4, thereby allowing all the ceramic membrane tubes 3 to be removed from the mounting plate 1, thus enabling flexible installation and removal.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
