Description

Technical Field

[0001] The utility model relates to the technical field of viscose filament production, in particular to a filtering device for a soft water tank of an R535A type filament spinning machine. Background Art

[0002] In the prior art, the R535A filament spinning machine is primarily used to produce viscose filament yarn. During the viscose filament production process, solid plant fibers are converted into liquid viscose (alkaline), which is then subjected to a chemical reaction in a coagulating solution (acid bath). After the acid and alkali are neutralized, the viscose is solidified into a filament bundle. After the filament bundle emerges from the coagulating bath, some coagulating liquid remains on the bundle, causing it to continue coagulating until it reaches the middle of the deacidification roller. At this point, the remaining coagulating liquid on the bundle must be washed away with soft water in the middle of the deacidification roller to achieve a neutral chemical profile. The soft water washing process is a critical step in yarn formation. Because soft water inherently contains fine ions such as magnesium and calcium, as well as other microbial impurities, substandard soft water quality can easily clog the spray nozzles during washing, preventing the filament bundle from being thoroughly rinsed, thus affecting the quality of the subsequent yarn cake. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing technology, the purpose of the invention of the utility model is to provide a soft water tank filter device for a filament spinning machine to remove inherent sulfides and microbial impurities in the soft water, so as to ensure that the filament bundle reaches the neutral process index after being washed with soft water on the deacidification roller, thereby meeting production needs.

[0004] To achieve the above-mentioned purpose of the invention, the utility model includes a soft water tank, a soft water inlet pipe, and a soft water outlet pipe; the inner wall of the soft water tank is symmetrically fixed with a card slot, the middle of which is inserted into the filter plate 1 and the filter plate 2, the filter plate 1 and the filter plate 2 are respectively provided with small holes, a sponge block is installed between the filter plate 1 and the filter plate 2, the soft water tank is provided with a soft water inlet pipe on one side of the filter plate 2, and the soft water tank is provided with a soft water outlet pipe on one side of the filter plate 1, soft water enters the soft water tank through the soft water inlet pipe, is filtered by the filter plate 2, the sponge block, and the filter plate 1, and then flows out through the soft water outlet pipe.

[0005] Furthermore, the soft water inlet pipe is located at the upper part of the soft water tank body, and the soft water outlet pipe is located at the lower part of the soft water tank body.

[0006] Furthermore, the filter plate 1 and the filter plate 2 are made of PVC plates, and the small holes on the filter plate 1 and the filter plate 2 are evenly distributed along the filter plate 1 and the filter plate 2.

DETAILED DESCRIPTION

[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. Example 1

[0014] like Figure 1 As shown, the utility model includes a soft water tank 1, a soft water inlet pipe 5, and a soft water outlet pipe 6; a card slot 7 is symmetrically fixed on the inner wall of the soft water tank 1, and a filter plate 2 and a filter plate 2 3 are inserted in the middle of the card slot 7. Small holes are respectively opened on the filter plate 1 2 and the filter plate 2 3. A sponge block 4 is installed between the filter plate 1 2 and the filter plate 2 3. The size of the sponge block 4 is consistent with that of the filter plate 1 2 and the filter plate 2 3. The sponge block 4 of this application is a high-density sponge. After the soft water flows through the sponge block 4, the sulfide and impurities in the soft water can be filtered out. The thickness and density of the sponge block 4 are sufficient to ensure that the impurities in the soft water can be filtered out. A soft water inlet pipe 5 is provided on the soft water tank 1 on one side of the filter plate 2 3, and a soft water outlet pipe 6 is provided on the soft water tank 1 on one side of the filter plate 2. Soft water enters the soft water tank 1 through the soft water inlet pipe 5, is filtered by the filter plate 2 3, the sponge block 4, and the filter plate 1, and then flows out through the soft water outlet pipe 6.

[0015] Preferably, the soft water inlet pipe 5 is located at the upper part of the soft water tank 1, and the soft water outlet pipe 6 is located at the lower part of the soft water tank 1. The top-in and bottom-out structural configuration of the present application is more conducive to the removal and filtration of impurities in the water.

[0016] Preferably, the first filter plate 2 and the second filter plate 3 are made of PVC plates. PVC plates are lightweight, acid-resistant, and easy to clean. The small holes on the first filter plate 2 and the second filter plate 3 are evenly distributed along the first filter plate 2 and the second filter plate 3. In this specific embodiment, each PVC filter plate consists of six rows of small holes, with thirty-two small holes evenly distributed in each row. The configuration of the small holes is sufficient to ensure the filtering effect and efficiency of soft water, and to ensure the rinsing quality of the tow on the deacidifying roller.

[0017] Preferably, the soft water outlet pipe 6 is connected to the spray nozzle 22 of the filament spinning machine. The spray nozzle 22 is located on the rinsing boat 21. The filtered soft water is sprayed and cleaned on the acidic tow on the rinsing boat 21 through the spray nozzle 22.

[0018] As Figure 3 shown, during use, in the production process of the R535A type filament spinning machine, viscose is evenly and quantitatively input into the swing pipe 11 by the pump bridge 10 and the metering pump, and is pressed out of the small holes of the spinneret 14 through the filter element, filter sleeve 12, and curved pipe 13 to form a viscose fine stream. The viscose fine stream undergoes a chemical reaction in the acid bath 15 (coagulation bath) and solidifies into a tow 16. Then, the tow 16 is led out of the coagulation bath and passes through the acid scraping rod, drafting disk, upper and lower coagulation rollers 17, upper and lower deacidifying rollers 18, funnel 19, and centrifugal can 20 to form a cake. The soft water inlet pipe 5 of the present application is connected to a water source, and the soft water outlet pipe 6 is connected to the spray nozzle 22 of the filament spinning machine. The spray holes of the spray nozzle are small round holes with a diameter of 1 mm. The soft water tank 1 is located above the rinsing boat 21 of the spinning machine. Soft water enters one side of the soft water tank 1 through the soft water inlet pipe 5, then flows to the other side of the soft water tank 1 through the second filter plate 3, sponge block 4, and first filter plate 2. The filtered soft water is connected to the spray nozzle 22 through the soft water outlet pipe 6 to spray and clean the acidic tow 16. The filtered soft water can ensure that the spray nozzle 22 is unblocked and ensure the spraying effect. Embodiment 2

Sponge blocks 4 are sequentially arranged between the first filter plate 2 and the second filter plate 3, and between the third filter plate 8 and the fourth filter plate 9. The multi-layer filtering device can meet the production needs of different processes. Or multiple groups of filter plates are arranged on the inner wall of the soft water tank 1, and sponge blocks 4 are arranged between the filter plates, and the filtering effect is better.
