Description

Technical Field

[0001] The utility model relates to the field of water washing devices, and more specifically, to a water washing device for producing chitosan fibers. Background Art

[0002] During the production process of chitosan fibers, a water washing device is required. When chitosan fibers are washed, due to the long-term circulation of the washing liquid, a small amount of fiber impurities will accumulate in the liquid. These impurities mainly come from processes such as fiber breakage, shedding, and dissolution. Many existing water washing devices often adopt relatively simple filtering methods, such as single-layer filter screens, when filtering the washing liquid. This method is difficult to effectively remove the fiber impurities accumulated in the washing liquid, resulting in a decline in the quality of the washing liquid, and further affecting the washing effect of chitosan fibers. If the impurities in the washing liquid are not fully removed, they will form residues on the surface of chitosan fibers, affecting the purity and service performance of chitosan fibers, and at the same time reducing the overall quality of the product. Moreover, the filtering device of the existing water washing device is inconvenient to disassemble and maintain, and when maintaining the filtering device, the water washing device needs to be shut down, resulting in the interruption of the water washing process and reducing the production efficiency.

[0023] The first chamber 9 and the second chamber 12 are fixedly connected by bolts and nuts (not shown in the figure), and there is a sealing ring between the first chamber 9 and the second chamber 12. The first chamber 9 has a first stepped portion 9.1 for accommodating the first ring portion 10, and the second chamber 12 has a second stepped portion 12.1 for accommodating the second ring portion 13.

[0024] Working principle: In the water washing device of the present application, when the water washing liquid is circulating normally, the valve unit is closed, the first valve and the second valve are opened, and filtration is achieved by using the filtration device. After the water washing liquid enters the filtration device, it will first pass through the first filter screen for preliminary filtration, and then the water washing liquid will continue to flow to the second filter screen for secondary filtration. Through the double filtration mechanism, it can ensure that the impurities in the water washing liquid are effectively removed, thereby ensuring the water washing effect of the water washing liquid.

[0025] After the filtration device is used for a period of time, impurities will gradually accumulate on the filter screen, affecting the filtration effect. Therefore, it is necessary to regularly disassemble and maintain the filtration device. Before maintenance, first open the valve unit and close the first valve and the second valve to ensure that the continuity of water washing is not affected. Then disassemble the filtration device, and it is convenient to carry out maintenance work such as cleaning and replacing the filter screen. At this time, the filter screen unit plays a filtering role, and since the filter screen unit is used for a short time and does not generate many impurities, the maintenance period is longer. After the maintenance work of the filtration device is completed, install the filtration device, and then open the first and second valves and close the valve unit.
