[0012] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0013] Example 1:

[0014] like Figure 1-Figure 3 As shown, the utility model discloses a slurry reflux device for whole slurry, including a slurry immersion tank 1, yarn guide rollers 2 are arranged at both ends of the upper part and inside the slurry immersion tank 1, one end of the slurry immersion tank 1 is the input end, and the other end of the slurry immersion tank 1 is the output end; a filter box 3 is arranged on the side wall of the slurry immersion tank 1 at the input end, the filter box 3 is connected with the bottom of the input end of the slurry immersion tank 1, and a filter screen 8 is vertically arranged in the filter box 3, the filter screen 8 divides the filter box 3 into two independent cavities, one cavity directly connected to the filter box 3 is the filter front cavity 6, and the other cavity is directly connected to the filter box 3. The cavity is a post-filtration cavity 7. The filter box 3 within the range of the post-filtration cavity 7 is connected to the output end of the slurry immersion tank 1 through a pipe 5. A circulation pump 13 is provided on the pipe 5. A vertical downward cylinder 4 is provided on the top of the filter box 3 within the range of the front filtration cavity 6. The telescopic end of the cylinder 4 passes through the filter box 3 and enters the front filtration cavity 6. The telescopic end of the cylinder 4 is sealed with the filter box 3. A scraper 9 is fixed on the telescopic end of the cylinder 4 in the front filtration cavity 6. When the scraper 9 moves downward, it fits with the filter screen 8. The scraper 9 is used to scrape off impurities on the filter screen 8.

[0015] During the actual sizing process, the yarn is fed into the sizing tank 1 from the yarn guide roller 2 at the input end, passes downward around the yarn guide roller 2 at the bottom of the sizing tank 1, and is then output from the yarn guide roller 2 above the sizing tank 1 at the output end. The sizing tank 1 is filled with sizing, so the yarn comes into contact with the sizing after entering the sizing tank 1. The yarn delivery speed is controlled according to actual needs and the length of the sizing tank 1 to ensure the contact time between the yarn and the sizing.

[0016] A filter box 3 is provided at the bottom of the input end of the slurry soaking tank 1. The filter screen 8 in the filter box 3 divides the filter box 3 into a front filtration chamber 6 and a rear filtration chamber 7. The rear filtration chamber 7 is connected to the output end of the slurry soaking tank 1 through a pipe 5 and a circulation pump 13. In this way, the slurry is input from the slurry soaking tank 1 into the front filtration chamber 6 of the filter box 3, filtered by the filter screen 8, and then enters the rear filtration chamber 7. It is then transported to the slurry soaking tank 1 through the circulation pump 13, thereby realizing slurry circulation. During the circulation process, it can effectively prevent some components in the slurry from precipitating, making the slurry more uniform and having a better slurry soaking effect on the yarn. In addition, impurities such as fibers and lint that fall from the yarn during the slurry soaking process will be filtered by the filter screen 8, blocked on the filter screen 8, and unable to circulate into the rear filtration chamber 7, thereby keeping the slurry in the slurry soaking tank 1 clean at all times, thereby improving the slurry soaking quality of the yarn.

[0017] After a long period of filtration, a large amount of impurities such as fibers will accumulate on the filter screen 8. The cylinder 4 can be used to drive the scraper 9 to move downward, and the scraper 9 is in contact with the filter screen 8. The scraper 9 can be used to scrape off the fibers and other impurities on the filter screen 8 and deposit them at the bottom of the filter front chamber 6 to ensure the smooth flow of the filter screen 8, maintain stable filtration efficiency and slurry reflux efficiency, and ensure stable and reliable equipment operation.

[0018] A downwardly recessed storage tank 10 is provided at the bottom of the filter box 3, next to the filter screen 8 within the pre-filter chamber 6. A drain pipe 11 is provided at the bottom of the storage tank 10, and a drain valve 12 is installed on the drain pipe 11. To temporarily store impurities scraped from the filter screen 8 by the scraper 9, the storage tank 10 is provided at the bottom of the side of the filter screen 8. The storage tank 10 is located within the pre-filter chamber 6. Impurities scraped by the scraper 9 enter the storage tank 10 directly. Once a certain amount of impurities has been stored, the drain valve 12 can be opened directly to discharge the impurities from the drain pipe 11. This configuration facilitates the cleaning of impurities without requiring downtime, thereby improving efficiency.

[0019] The storage tank 10 is a rectangular structure, and its length is the same as the horizontal length of the filter screen 8. The scraper 9 is located directly above the storage tank 10. The storage tank 10 is rectangular, and this rectangular structure can cooperate with the scraper 9. The scraper 9 can directly enter the top of the storage tank 10 during its downward movement. In this way, the scraper 9 can directly push the impurities on the filter screen 8 into the storage tank 10 after scraping them off. This allows the impurities to completely enter the storage tank 10 and avoid re-attachment to the filter screen 8. This improves the cleaning effect and also facilitates the subsequent discharge of impurities through the sewage pipe 11.

[0020] The top of the storage tank 10 is a rectangular structure, the bottom thereof is a circular structure, and the sidewall of the storage tank 10 transitions from a rectangular structure to a circular structure.

[0021] The overall structure of the storage tank 10 is rectangular at the top and circular at the bottom, and is transitioned by side walls. In this way, impurities will not be blocked during the sewage discharge process, and it is not easy to be blocked, and the sewage discharge is smoother and more efficient.
