Description

Technical Field

[0001] This utility model belongs to the field of spinning processing technology, and specifically relates to a spinning filter device for spinning processing. Background Technology

[0002] In the spinning process, the spinning solution (usually a mixture containing fibers, oils, emulsifiers, and water) needs to be filtered. During preparation or recycling, the spinning solution is easily contaminated with natural impurities from the raw materials (such as cottonseed hull fragments and oil residues on the surface of synthetic fibers) or solid particles from the environment, such as dust and short fiber lint. If these impurities are not filtered, they will form defects during spinning, leading to yarn breakage or uneven strength, affecting the quality of the finished product. Therefore, a spinning filtration device for spinning processing is needed to filter the spinning solution.

[0003] Existing traditional spinning filtration devices generally employ a single-unit filter cartridge design, which presents a significant efficiency bottleneck: when the filter cartridge needs cleaning or replacement due to impurity buildup, the filtration operation must be completely halted, causing the entire production line to stop. For example, after a single-unit filter cartridge intercepts impurities such as short fibers and grease, it requires manual disassembly and cleaning of the filter media. During this process, the spinning solution cannot be recycled, resulting in raw material waste and equipment idling. Therefore, a spinning filtration device for spinning processing is needed to help solve this problem. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This specific embodiment is a spinning filter device for spinning processing, such as... Figure 1-4 As shown, the spinning filter device for spinning processing includes a collecting cylinder 1, a support leg 2 installed at the bottom of the outer side of the collecting cylinder 1, an exhaust pipe 17 installed at the top of the top cover 16, a pressure valve 18 and a valve installed at the exhaust pipe 17, a filter chamber opened inside the collecting cylinder 1, a drain outlet opened at the bottom of the collecting cylinder 1, a drain pipe 3 installed at the drain outlet, a water inlet installed at the top of one side of the collecting cylinder 1, and an auxiliary water pump 19 installed at the water inlet. The top cover of the collecting cylinder 1... The top cover 16 is provided. The top of the outer side of the collection tube 1 is symmetrically fixed with fixing ears 21. Fixing components 20 are installed at the fixing ears 21. The top cover 16 is symmetrically provided with fixing holes for fixing components 20. The fixing components 20 include hinge ears 22 that are hinged to the fixing ears 21. A screw rod 23 is vertically fixed to the hinge ears 22. A sleeve 24 is sleeved on the screw rod 23. The screw rod 23 and the sleeve 24 are threaded together. The bottom of the sleeve 24 is pressed against the top of the top cover 16.

[0028] The fixed component 20, through the threaded engagement of the screw 23 and the sleeve 24, enables the top cover 16 to be quickly tightened and loosened. Compared with the traditional bolt fixing method, it can significantly shorten the disassembly and assembly time of the top cover 16, facilitate the regular cleaning of the filter chamber or replacement of the internal filter material, and at the same time, the sealing structure is reliable, effectively preventing liquid leakage during the filtration process.

[0029] A support frame 4 is symmetrically protruding from the middle section of the collection cylinder 1. A through-hole is opened in the middle section of the collection cylinder 1, and an auxiliary filter assembly 5 is installed at the through-hole. The filter assembly 5 is set at the top of the support frame 4. The filter assembly 5 includes a mounting frame 6. Handles 15 are fixed on both sides of the mounting frame 6. Guide grooves 61 are symmetrically opened on both sides of the mounting frame 6. A snap-fit ​​strip is opened on the support frame 4 for the guide grooves 61 to engage. Positioning holes are symmetrically opened in the guide grooves 61. A fixing bolt is threaded on the collection cylinder 1. The fixing bolt and the positioning hole are fitted together for positioning. A through cavity 7 is symmetrically opened on the mounting frame 6. A filter cylinder 8 is installed in the through cavity 7. A limit groove 62 is opened on the side of the through cavity 7. A limit block 9 is protruding from the outer side of the filter cylinder 8. The limit groove 62 and the limit block 9 are fitted together for fixation.

[0030] By setting two sets of filter cartridges 8 in the filter assembly 5, when one set needs to be cleaned or replaced due to impurity accumulation, the other set can immediately take over the filtration task. The two sets of filter cartridges 8 are arranged side by side through the through cavity 7 of the mounting frame 6. There is no need to stop the entire equipment. Continuous operation can be maintained simply by switching the operating status of the filter cartridges 8, which significantly reduces the production efficiency loss caused by downtime maintenance. At the same time, the filter assembly 5 adopts a snap-fit ​​structure between the mounting frame 6 and the guide groove 61 of the support frame 4 to realize the rapid positioning and horizontal calibration of the filter unit. With the vertical limiting design of the limiting block 9 and the limiting groove 62, it is ensured that there is no axial displacement after the filter cartridge 8 is installed, which improves the filtration stability. The modular structure allows for the quick replacement of filter cartridges 8 with different precision according to the type of impurities in the spinning solution, which can meet diverse filtration needs.

[0031] The mounting bracket 6 has a positioning cavity, and a positioning component 10 is installed in the positioning cavity. A fixing hole is provided on the outer side of the limiting block 9. The fixing hole and the positioning component 10 are fixed together. The positioning component 10 includes a positioning pin 11 that is slidably disposed in the positioning cavity. A connecting rod 12 is fixed on the side of the positioning pin 11 away from the through cavity 7. The connecting rod 12 extends through the positioning cavity. A connecting plate 14 is fixed to the end of the connecting rod 12 that extends out of the positioning cavity. A top pressure spring 13 that helps the positioning pin 11 to push out is installed in the positioning cavity.

[0032] The positioning component 10 is set up so that the positioning pin 11 is pushed into the fixing hole of the limiting block 9 by the top pressure spring 13, forming a reliable axial locking mechanism. This design avoids the filter cylinder 8 from loosening or displacement due to liquid impact during the filtration process, ensuring stable filtration accuracy. When replacement is required, the locking can be released simply by pulling the connecting plate 14. The operation is simple and the positioning is accurate.

[0033] Working principle:

[0034] The top cover 16 is fixed to the top of the collection cylinder 1 by the fixing component 20. The hinge ear 22, which is hinged to the fixing ear 21, drives the screw 23 to rotate. The screw 23 is threadedly engaged with the sleeve 24, so that the bottom of the sleeve 24 presses against the top of the top cover 16 to form a sealing structure and prevent liquid leakage during the filtration process.

[0035] The filter assembly 5 is quickly positioned horizontally by engaging with the snap-fit ​​strips of the support frame 4 through the guide grooves 61 on both sides of the mounting frame 6, and the mounting frame 6 is fixed by fixing bolts when the filter cylinder 8 is directly below the collection cylinder 1.

[0036] The through cavity 7 on the mounting bracket 6 receives the filter cartridge 8. The limiting block 9 on the outside of the filter cartridge 8 is embedded in the limiting groove 62 on the side of the through cavity 7 to complete the initial vertical fixation. The top pressure spring 13 in the positioning assembly 10 pushes the positioning pin 11 into the fixing hole on the outside of the limiting block 9 to achieve axial locking of the filter cartridge 8. When the filter cartridge 8 needs to be replaced, the connecting plate 14 is pulled outward to move the connecting rod 12, so that the positioning pin 11 is disengaged from the fixing hole, and can be quickly disassembled.

[0037] The water pump 19 draws the spinning liquid to be filtered from the inlet into the filter chamber of the collection cylinder 1. The liquid passes through the filter cylinder 8 in the filter assembly 5 for multi-stage filtration. The separated impurities are trapped on the inner wall of the filter cylinder 8. The filtered liquid is discharged through the bottom drain pipe 3. The exhaust pipe 17 works with the pressure valve 18 to adjust the air pressure in the filter chamber to prevent the filtration efficiency from being affected by negative pressure.

[0038] All technical features in this embodiment can be freely combined according to actual needs.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
