Description

Technical Field

[0001] The present invention relates to the technical field of filters, and in particular to a microporous precision filter and a filtering method. Background Art

[0002] Microporous precision filter, as an advanced separation technology equipment, mainly uses microporous membrane technology for precise particle separation. The core component of microporous precision filter is microporous filter medium, which is usually made of polyethylene (PE), polypropylene (PP) or other high-performance materials. These materials have good chemical stability, temperature resistance and mechanical strength, and can cope with a variety of complex industrial environments. Under the action of pressure difference, the solid-liquid or gas-solid mixture to be filtered is forced to pass through the microporous medium, where solid particles larger than the micropore diameter are intercepted on the surface or inside the medium, while clean liquid or gas flows out through the medium, thereby achieving efficient separation.

[0003] In the construction of precision filters, in order to ensure the stable installation of multiple filter elements inside, a dedicated fixing device is required to lock the filter elements in a predetermined position one by one in a serialized manner. In addition, the water inlet pipe of the precision filter is designed to be fixedly pointed to a specific filter element, and this filter element is strictly set to a non-rotatable state to ensure that the fluid flows through the filter element in a constant direction, maintaining the stability and efficiency of the filtration process.

[0004] Defects of the prior art: The use of a dedicated fixing device and a serialized installation method means that each filter element needs to be fixed individually, which increases the time and labor costs during the installation process; the water inlet pipe is fixed toward one filter element, which causes the filter element to be subjected to a larger water flow impact, while the flow of other filter elements may be relatively small. Due to uneven flow distribution, the filter element that is directly impacted may be clogged faster, thereby reducing the filtering efficiency of the entire filter.

[0005] Therefore, the present application provides a microporous precision filter and a filtering method to meet the needs. Summary of the invention

A plurality of filter element limiting sleeves 61 are fixedly arranged in an annular shape on the top of the lower turntable 6. The filter element limiting sleeves 61 are adapted to the filter element. The water inlet pipe 14 is located below the upper turntable 4 to prevent the sewage entering from the upper turntable 4 from flowing onto the upper turntable 4. A plurality of circular holes 41 are opened in an annular shape on the upper turntable 4. The interior of the upper turntable 4 is hollow, and the circular holes 41 are connected to the interior of the upper turntable 4.

[0038] A clamping assembly 8 is provided inside the upper turntable 4. The clamping assembly 8 can clamp multiple filter elements to prevent the filter elements from moving during operation. The clamping assembly 8 includes a driving shaft 82 rotatably connected to the bottom of the upper turntable 4. A driving gear 81 is fixedly sleeved on the outside of the driving shaft 82 and close to its bottom. The bottom of the upper turntable 4 is rotatably connected to multiple driven shafts 88 in an annular manner. A driven gear 89 and a driven bevel gear 87 are fixedly sleeved on the outside of the driven shaft 88. The driven bevel gear 87 is located above the driven gear 89. The driving gear 81 is meshed and connected with multiple driven gears 89. The driving gear 81 can drive multiple driven gears 89 to rotate simultaneously, and the driven gears 89 are arranged one-to-one with the circular holes 41. A double-headed screw rod 83 is arranged above the driven shaft 88. The double-headed screw rod 83 and the circular holes 41 are arranged one-to-one.

The clamping assembly 8 also includes a plurality of guide columns, which are arranged one by one with the double-headed screw rod 83, and the guide columns pass through the corresponding two slide plates 84. The two ends of the guide columns are fixedly connected with a second support plate, and the bottom of the second support plate is fixedly connected to the inner bottom of the upper turntable 4.

[0039] The filter body 1 is provided with a clamping trigger assembly 7. When the top cover 15 is moved vertically downward to be installed with the filter body 1, the clamping assembly 8 can be operated by cooperating with the clamping trigger assembly 7 to clamp a plurality of filter elements.

[0040] When the top cover 15 moves vertically downward, the clamping trigger assembly 7 can rotate the active shaft 82, the active shaft 82 drives the active gear 81 to rotate, the active gear 81 drives the driven gear 89 to rotate, the driven gear 89 drives the driven shaft 88 and the driven bevel gear 87 to rotate, the driven bevel gear 87 drives the active bevel gear 86 to rotate by meshing with the active bevel gear 86, the active bevel gear 86 drives the double-headed screw 83 to rotate, so that the two slides 84 on the double-headed screw 83 approach each other, and then the corresponding two arc-shaped clamping plates 85 approach each other, thereby clamping the corresponding filter element.

[0041] When the top cover 15 moves vertically downward to be installed with the filter body 1, it can cooperate with the clamping trigger assembly 7 to allow the clamping assembly 8 to operate to clamp the filter element. No additional manual operation is required, which simplifies the installation process and reduces the risk of loosening or damage of the filter element due to improper manual operation. When the filter element needs to be replaced, only the top cover 15 needs to be removed, and the clamping assembly 8 will automatically release the filter element, making the filter element replacement process simple and quick, reducing maintenance costs.

[0042] The bottom of the top cover 15 is rotatably connected with a rectangular sleeve 9, the bottom of the rectangular sleeve 9 is open, the clamping trigger assembly 7 includes a first fixed shaft 71 rotatably connected to the top of the upper turntable 4, the first fixed shaft 71 passes through the top wall of the upper turntable 4 and is fixedly connected to the active rotating shaft 82, the top of the first fixed shaft 71 is fixedly connected with a first bevel gear 72, the top of the upper turntable 4 is fixedly connected with a fixed plate 73, the side of the fixed plate 73 close to the first bevel gear 72 is rotatably connected with a second fixed shaft 74, the outer side of the second fixed shaft 74 is fixedly sleeved with a transmission gear 75 and a second bevel gear 76, the second bevel gear 76 is meshed with the first bevel gear 72, the top of the upper turntable 4 is fixedly connected with a guide housing 79, the inside of the guide housing 79 The guide shell 79 is hollow and open at the top and bottom. The clamping trigger assembly 7 also includes a transmission rack 77 that can be raised and lowered. The lower end of the transmission rack 77 is slidably connected to the inner side of the guide shell 79, and the transmission rack 77 will not detach from the guide shell 79. The top of the transmission rack 77 is fixedly connected with a vertically upward extension portion 771. A second spring 78 is fixedly connected between the bottom of the transmission rack 77 and the top of the upper turntable 4. The second spring 78 is compressed during the downward vertical movement of the transmission rack 77. When no force is applied to the transmission rack 77, the rebound force of the second spring 78 can drive the transmission rack 77 to reset. The extension portion 771 is adapted to the rectangular sleeve 9, and the top of the extension portion 771 can enter the inner side of the rectangular sleeve 9.

[0043] When the top cover 15 moves vertically downward to be installed with the filter body 1, the top cover 15 drives the rectangular sleeve 9 to move vertically downward, and the rectangular sleeve 9 and the extension portion 771 move relative to each other, so that the extension portion 771 enters the inner side of the rectangular sleeve 9. As the rectangular sleeve 9 continues to move vertically downward, the top of the extension portion 771 abuts against the inner wall of the rectangular sleeve 9, forcing the extension portion 771 and the transmission rack 77 to move downward as a whole. The second spring 78 is compressed, and the transmission rack 77 drives the transmission gear 75 to rotate during the vertical downward movement. The transmission gear 75 drives the second fixed shaft 74 and the second bevel gear 76 to rotate as a whole, and the second bevel gear 76 drives the first bevel gear 72 and the first fixed shaft 71 to rotate. Because the first fixed shaft 71 is vertically fixedly connected to the active rotating shaft 82, the first fixed shaft 71 drives the active rotating shaft 82 to rotate, thereby realizing that when the top cover 15 moves vertically downward to be installed with the filter body 1, the clamping trigger assembly 7 can rotate the active rotating shaft 82.

[0044] A driving assembly 3 for driving the upper turntable 4 and the lower turntable 6 to rotate is provided on the filter body 1. The driving assembly 3 includes a driving motor 31 fixedly arranged on the outside of the filter body 1. A mounting seat 18 is fixedly arranged on the outside of the filter body 1.

The output end of the driving motor 31 passes through the side wall of the filter body 1 and is fixedly connected to a driving bevel gear 32. A passive bevel gear 33 is fixedly connected to the top of the upper turntable 4. The passive bevel gear 33 is meshed with the driving bevel gear 32.

[0045] When in use, multiple filter elements are passed through the circular hole 41 in sequence, and the bottom of the filter element is placed on the inner side of the corresponding filter element limiting sleeve 61, so that the top cover 15 is moved vertically downward to be installed with the filter body 1. When the clamping assembly 8 clamps the multiple filter elements, the driving motor 31 is started, and the output end of the driving motor 31 drives the driving bevel gear 32 to rotate, and the driving bevel gear 32 drives the passive bevel gear 33 to rotate, and the passive bevel gear 33 drives the upper turntable 4 to rotate, and the upper turntable 4 drives the lower turntable 6 to rotate through the connecting rod 5, thereby driving the multiple filter elements inside the upper turntable 4 and the lower turntable 6 to rotate; one of the filter elements is rotated to the position corresponding to the water inlet pipe 14, and when the use time of this filter element reaches the specified use time, in order to avoid the filter element that is directly impacted from being quickly blocked, it is necessary to start the driving motor 31 to rotate the multiple filter elements, and rotate the next filter element to the position corresponding to the water inlet pipe 14.

[0046] By regularly replacing the position of the filter element in use, you can avoid a single filter element being quickly blocked due to long-term impact of water flow. When a filter element is close to being blocked, you can rotate it and replace it with a new or cleaner filter element to ensure that the filtration efficiency is always maintained at a high level.

[0047] A filter element position assembly 2 is provided on the filter body 1, and the filter element position assembly 2 can track the position of the first filter element.

The bottom of the top cover 15 is fixedly connected to a column limiting sleeve 25, and the top and bottom of the column limiting sleeve 25 are open. The interior of the body limiting sleeve 25 is hollow, and the lifting column 21 slides through the column limiting sleeve 25. The guiding effect provided by the column limiting sleeve 25 helps to prevent the lifting column 21 from shifting or tilting during the movement. The filter element position assembly 2 also includes a fixed column 27 fixedly connected to the top of the upper turntable 4, and the fixed column 27 corresponds to the position of one of the circular holes 41. The top of the fixed column 27 is fixedly connected to the lower movable block 26, and the top of the lower movable block 26 is inclined, and the inclined portion of the lower movable block 26 cooperates with the inclined portion of the upper movable block 24. The inclined portion of the lower movable block 26 can conflict with the inclined portion of the upper movable block 24, forcing the upper movable block 24 to be lifted up.

[0048] In the initial state, one of the filter elements corresponds to the position of the water inlet pipe 14, and the inclined portion of the lower movable block 26 abuts against the inclined portion of the upper movable block 24, the lifting column 21 and the base plate 22 are in a completely lifted state, and when the use time of this filter element reaches the specified use time, the drive motor 31 is started to rotate the next filter element to the position corresponding to the water inlet pipe 14, the lower movable block 26 is out of contact with the upper movable block 24, the first spring 23 drives the base plate 22 and the lifting column 21 to descend, and the lifting column 21 and the base plate 22 are not lifted until the next filter element is used. After the core has reached the specified usage time, the drive motor 31 is started again to rotate the subsequent filter element to the position corresponding to the water inlet pipe 14, and this cycle is repeated until the inclined portion of the lower movable block 26 abuts against the inclined portion of the upper movable block 24 again, forcing the upper movable block 24 to gradually rise, and the upper movable block 24 drives the lifting column 21 and the base plate 22 to return to the lifted state again, indicating that the first filter element that has been used has rotated to the position corresponding to the water inlet pipe 14 again, that is, all the filter elements have been used, and all the filter elements inside the filter body 1 need to be replaced.

[0049] An annular groove (not shown in the figure) is provided at the bottom of the top cover 15, and the top of the rectangular sleeve 9 is slidably connected in the annular groove.
