Description

Technical Field

[0001] The utility model relates to the technical field of differential fiber production equipment, in particular to a fluid filtering device for differential fiber production. Background Art

[0002] Differentiated fibers usually refer to fibers that have been physically or chemically modified based on their original composition, making the fiber's morphological structure and physical and chemical properties significantly different from those of conventional chemical fibers. In the production process of differentiated fibers, corresponding fluids are required. These fluids will be mixed with impurities during production, such as fine particles generated during the mixing process or particles contained in additives. If the fluid is not filtered, these impurities will have a greater negative impact on subsequent production, not only increasing the defective rate, but also greatly increasing the cost of equipment maintenance and repair. Therefore, corresponding filtration and cleaning treatments are required.

[0003] In order to complete the filtration work smoothly, the traditional process usually chooses a simple filtration device and installs a corresponding filter element in the pipeline. Although this can complete the filtration work stably, long-term use will cause the filter element to be blocked, which will make it impossible to complete the fluid filtration work normally; and the impurities filtered out of the pipeline or filter box cannot be discharged and cleaned in time. The filter element is also very troublesome to replace and requires complex manual operation, which is not conducive to the user's efficient work and affects the overall production efficiency. Therefore, further improvement is needed. Utility Model Content

[0021] The specific embodiments of the present invention are further described in detail below with reference to the accompanying drawings:

[0022] like Figures 1 to 3 As shown, a fluid filtration device for differentiated fiber production includes a filter box 1 and a filter screen cleaning structure arranged on the filter box 1, wherein the interior of the filter box 1 is provided with an arc-shaped inner cavity 2, one end of the filter box 1 is provided with a feed port 9, and the outer end of the feed port 9 is fixedly installed with a feed pipe 11 connected to the inner cavity 2; the other end of the filter box 1 is provided with a discharge port 10, and the outer end of the discharge port 10 is fixedly installed with a discharge pipe 12 connected to the inner cavity 2. The outer wall of the filter box 1 is also provided with a rotating port 3. A rotating motor 4 is fixedly mounted on the outer wall of the filter box 1 near the rotating port 3 via a motor base. A rotating shaft 5 is coaxially fixed to the output end of the rotating motor 4. A circular working disk 6 is coaxially fixed to the rotating shaft 5. Two symmetrically arranged sector plates 7 are fixedly mounted on the circumferential outer wall of the working disk 6. Two symmetrically arranged filter plates 8 are fixedly mounted on the outer wall of the working disk between the two sector plates 7. The two filter plates 8 and the two sector plates 7 are sequentially spaced along the circumference of the working disk 6, together forming the outer ring structure of the working disk 6. Each filter plate 8 is provided with evenly spaced filter holes for fluid to pass through and filter impurities. The working disc 6 with the filter plate 8 is inserted into the rotating port 3 and extends into the inner cavity of the filter box 1, located between the feed port 9 and the discharge port 10. The curvature of the inner cavity 2 of the filter box 1 is consistent with the curvature of the filter plate 8, so that the outer edge of the filter plate 8 can be closely pressed against the inner cavity 2 of the filter box, completing full coverage and sufficient filtration to avoid omission problems. A high-pressure rotary sealing ring is fixedly installed at the rotating port 3 to form a rotary seal with the working disc 6 and the sector plate 7.

[0023] The filter screen cleaning structure is fixedly mounted on the outer wall of the filter box 1 provided with the rotating port 3 via a support frame 15, and includes a cleaning pipe 17 and a collection pipe 16. The support frame 15 includes two L-shaped support plates, which are fixedly mounted on the outer wall of the filter box on both sides of the rotating port 3 of the filter box 1. The cleaning pipe 17 and the collection pipe 16 are fixedly mounted on the top ends of the two L-shaped support plates, and the two are coaxially arranged, facing the filter plate 8 located outside the filter box 1, and the cleaning pipe 17 is located on the downstream side of the filter plate 8. The cross-sections of the ends of the cleaning pipe 17 and the collection pipe 16 near the filter plate 8 are the same as the arc structure of the filter plate 8. The diameters of the cleaning pipes 17 and the collection pipe 16 are equal to the length of the outer arc of the filter plate 8, and the areas are slightly larger than the cross-sections of the filter plate 8. A detachable collecting bag is also installed at the end of the collecting pipe 16 away from the filter plate 8; a blowing mechanism 18 is fixedly installed at the end of the cleaning pipe 17 away from the filter plate 8. The blowing mechanism 18 uses a blowing pump, and its air outlet end is fixedly connected to the cleaning pipe 17, which can blow impurities on the filter plate 8 into the collecting pipe 16 and collect and process them through the collecting bag.

[0024] The above-mentioned feed pipe 11 is provided with an internal thread on the inner side wall of the outer end, which is threadedly connected to an external threaded pipe 13, and is sealed for feeding; the outer side wall of the outer end of the discharge pipe 12 is provided with an external thread, which is threadedly connected to an internal threaded pipe 14, and is sealed for discharging; the above-mentioned arrangement makes the fluid input very smooth.

[0025] The feed pipe 11 is also provided with a control switch structure, combined with Figure 2 As shown, it specifically includes a drive motor 22, a rotating block 20 and a butterfly valve 21, corresponding to the installation position of the control switch structure. A rotating groove 19 adapted to the rotating block 20 is opened on the side wall of the above-mentioned feed pipe 11, and the rotating block 20 can be tightly rotatably installed in the rotating groove 19 and is relatively sealed; the lower end of the rotating block 20 is fixedly connected to the output end of the drive motor 22; the drive motor 22 is fixedly installed on the outer wall of the feed pipe 11 through the motor base; the upper end of the rotating block 20 is fixedly connected to the butterfly valve 21, and the butterfly valve 21 is arranged inside the feed pipe 11, adapted thereto, and can fit the inner wall of the feed pipe 11 to complete the flow cutoff.

[0026] The specific operating principle is as follows: First, the motor 4 is running, which drives the rotation of the shaft 5, thereby driving the working disk 6 to rotate, and then driving one of the filter plates 8 to enter the inner cavity 2 of the filter box 1 through the rotating port 3. At this time, the two sector plates 7 are in a horizontal position, and together with the working disk 6, they engage the rotating port 3, and a high-pressure rotating seal completes the relative seal to prevent fluid leakage. Subsequently, the fluid enters the inner cavity 2 of the filter box 1 through the externally threaded pipe 13, the feed pipe 11, and the feed port 9, flows through the filter plate 8 to filter impurities, and the filtered fluid flows to the next process through the discharge port 10, the discharge pipe 12, and the internally threaded pipe 14. After the filtration process has been carried out for a period of time, the driving motor 22 starts to operate, and the butterfly valve 21 is driven to rotate and close through the rotating block 20, thereby intercepting the incoming fluid to prevent a large amount of fluid from entering the filter box 1 when the filter plate 8 is adjusted, thereby causing the fluid to overflow, thereby greatly ensuring the safety of the device operation; at this time, the rotating motor 4 starts to operate, driving the working disk 6 to rotate 180 degrees, and the new filter plate 8 at the top rotates into the inner cavity 2 of the filter box 1, and the used filter plate 8 rotates upward to between the cleaning pipe 17 and the collection pipe 16, and then the butterfly valve 21 opens, and the fluid flows and is filtered. The blowing pump of the blowing mechanism 18 starts to blow and clean the used filter plate 8 through the cleaning pipe 17, and the impurities enter the collection pipe 16 for collection and processing. After the cleaning is completed, the blowing mechanism 18 stops running. This reciprocating operation completes the filtration and cleaning of the filter plate 8, thereby improving the filtration efficiency.

[0027] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
