Description

Technical Field

[0001] This utility model relates to the technical field of porous ceramic processing equipment, and in particular to a device for refining the micropores on the surface of porous ceramic filter elements. Background Technology

[0002] Porous ceramics are ceramic filter materials made by sintering refractory raw materials with binders at high temperatures. Their internal structure has a large number of interconnected micropores with controllable pore size. In addition to being resistant to high temperature, high pressure, acid and alkali corrosion, they also have the characteristics of uniform pore size and high air permeability. Therefore, they can be widely used in filtration and other applications.

[0003] The filtration accuracy of porous ceramic filter elements is mainly determined by the pore size of the surface micropores. However, after the existing porous ceramic filter elements are manufactured, the pore size of the surface micropores is uneven and the pore size is too large, which does not meet the requirements. Currently, the commonly used micropore refinement methods mostly adopt physical grinding, which grinds the large pore material on the surface of the porous ceramic filter element to expose the smaller pore size in the lower layer. However, the existing porous ceramic filter elements need to be ground separately inside and outside the filter element during the grinding process, which cannot be processed at the same time. This results in a lot of time being wasted in processing a porous ceramic filter element, leading to low processing efficiency.

[0004] Therefore, we provide a device for refining the micropores on the surface of porous ceramic filter elements. Utility Model Content

[0026] Example: A device for refining the micropores on the surface of a porous ceramic filter element, such as... Figures 1-5As shown, the device includes a support base 1, a protective cover 2 installed on the upper end of the support base 1, two support blocks 3 symmetrically installed on the lower inner wall of the protective cover 2, two drive rollers 4 symmetrically rotated between the two support blocks 3, a synchronous wheel 5, a synchronous belt 6 and a motor 7 are installed inside the protective cover 2, a porous ceramic filter element 8 is installed above the two drive rollers 4, two limiting rotating rollers 9 are symmetrically installed above the porous ceramic filter element 8, an outer grinding column 11 is installed between the two limiting rotating rollers 9, an inner grinding column 13 is installed inside the porous ceramic filter element 8, and a multi-stage electric telescopic rod 14 is installed outside the inner grinding column 13.

[0027] The same end of the two drive rollers 4 is inserted through to the outer end of one of the support blocks 3. The outer end of the drive roller 4 is fixedly connected to the synchronous wheel 5. The motor 7 is fixedly connected to the lower inner wall of the protective cover 2. The output end of the motor 7 is also equipped with the synchronous wheel 5. The two drive rollers 4 are connected to the output end of the motor 7 through the synchronous wheel 5 and the synchronous belt 6.

[0028] The porous ceramic filter element 8 is located between two drive rollers 4. The outer surface of the porous ceramic filter element 8 is in contact with the outer surface of the drive roller 4. The drive roller 4 and the limiting rotating roller 9 are horizontally spaced apart. The outer surface of the porous ceramic filter element 8 is in contact with the outer surface of the limiting rotating roller 9.

[0029] A support plate 10 is provided above the two limiting rotating rollers 9. The lower ends of the limiting rotating rollers 9 and the support plate 10 are rotatably connected. The outer grinding column 11 is fixedly connected to the lower end of the support plate 10. The outer surface of the outer grinding column 11 is in contact with the outer surface of the porous ceramic filter element 8.

[0030] An electric cylinder 12 is installed at the upper end of the protective cover 2. The output end of the electric cylinder 12 is inserted through and inserted into the interior of the protective cover 2. The support plate 10 is fixedly connected to the output end of the electric cylinder 12.

[0031] A groove 201 is provided through one side surface of the protective cover 2. The multi-stage electric telescopic rod 14 is slidably disposed inside the groove 201, and the outer end of the multi-stage electric telescopic rod 14 is slidably connected to the outer surface of the protective cover 2.

[0032] The inner grinding column 13 is fixedly connected to the output end of the multi-stage electric telescopic rod 14, and the outer surface of the inner grinding column 13 is in contact with the inner wall of the porous ceramic filter element 8.

[0033] A screw cylinder is provided through one side of the inner wall of the slide groove 201. A screw rod 15 is screwed into the inside of the screw cylinder. The inner end of the screw rod 15 is rotatably connected to the outer surface of the multi-stage electric telescopic rod 14.

[0034] Before polishing the porous ceramic filter element 8, in order to ensure the stability of the porous ceramic filter element 8 during operation, two drive rollers 4 are set to initially position the porous ceramic filter element 8. During this process, in order to avoid the components inside the protective cover 2 from blocking the placement of the porous ceramic filter element 8, it is necessary to ensure that the output ends of the electric cylinder 12 and the multi-stage electric telescopic rod 14 are in the retracted state. At this time, the lower half of the porous ceramic filter element 8 is in a fixed state. In order to further ensure the stability of the porous ceramic filter element 8 during operation, the electric cylinder 12 is operated to push the support plate 10 down. The limiting rotating roller 9 moves down with the support plate 10 at the same time until the limiting rotating roller 9 is in contact with the upper half of the porous ceramic filter element 8, thus completing the full fixation of the porous ceramic filter element 8. During the movement of the support plate 10, the outer polishing column 11 moves synchronously. When the limiting rotating roller 9 is in contact with the porous ceramic filter element 8, the outer polishing column 11 will synchronously be in contact with the outer surface of the porous ceramic filter element 8.

[0035] At this point, the outer surface polishing assembly of the porous ceramic filter element 8 is in place. It is necessary to adjust and position the polishing assembly inside the porous ceramic filter element 8. First, the multi-stage electric telescopic rod 14 is operated to push the inner polishing column 13 into the interior of the porous ceramic filter element 8. Then, in order to ensure the precise polishing of the inner polishing column 13, it is necessary to ensure that the inner polishing column 13 is in contact with the inner wall of the porous ceramic filter element 8. By rotating the screw 15, based on the threaded connection between the screw 15 and the screw barrel, the screw 15 will drive the multi-stage electric telescopic rod 14 to slide horizontally in the slide groove 201 until the inner polishing column 13 is in contact with the inner wall of the porous ceramic filter element 8.

[0036] At this point, the porous ceramic filter element 8 has been fixed, and the inner and outer polishing components have been positioned. Since the positions of the inner polishing column 13 and the outer polishing column 11 cannot be moved, the porous ceramic filter element 8 needs to be rotated to achieve the polishing effect. By running the motor 7, and with the connection between the synchronous pulley 5 and the synchronous belt 6, the motor 7 will drive the drive roller 4 to rotate. While the drive roller 4 is rotating, under the action of friction, the drive roller 4 will synchronously drive the porous ceramic filter element 8 to rotate. Since the length of the outer polishing column 11 is greater than the length of the porous ceramic filter element 8, the outer surface of the porous ceramic filter element 8 will be automatically polished during the rotation of the porous ceramic filter element 8. Since the length of the inner polishing column 13 is smaller, in order to ensure the effective polishing of the inner polishing column 13, the multi-stage electric telescopic rod 14 will run synchronously during the rotation of the porous ceramic filter element 8. The extension speed of the multi-stage electric telescopic rod 14 is slow, thereby driving the inner polishing column 13 to move inside the porous ceramic filter element 8, ensuring the comprehensive polishing of the inner polishing column 13.

[0037] With the cooperation of the outer grinding column 11 and the inner grinding column 13, firstly, the inner and outer surfaces of the porous ceramic filter element 8 can be ground simultaneously without having to be divided into two steps, which reduces the time required for grinding the porous ceramic filter element 8 and further improves the grinding efficiency of the porous ceramic filter element 8. Secondly, it eliminates the need for manual hand-grinding of the porous ceramic filter element 8, further ensuring the uniformity of grinding the porous ceramic filter element 8 and guaranteeing the overall quality of the porous ceramic filter element 8.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
