Description

Technical Field

[0001] The utility model belongs to the technical field related to spinning, and particularly relates to a filtering structure for zero-water-washing return water of a spinning machine. Background Art

[0002] A spinning machine is a machine that makes a fiber-forming polymer solution or melt form filaments. According to different fiber spinning methods, spinning machines are divided into three types: wet spinning machines, melt spinning machines, and dry spinning machines. In the high-speed continuous spun viscose production, the zero water washing process of the spinning machine is realized through equipment technology transformation. Zero water washing is an important link in which the fiber is neutralized by water washing after solidification into a bundle. It can reduce the acid content in the fiber. Therefore, it is particularly important to ensure the smoothness and cleanliness of the zero water washing pipeline in daily production. The zero water washing pipeline still has the following disadvantages in actual use:

[0003] During the zero-water washing process of the spinning machine, the spinning machine is usually directly connected to the return pipe. The water in the zero-water washing process is not treated in any way and is directly returned. This causes the dirt and debris in the zero-water washing of the spinning machine to accumulate for a long time, which will cause the blockage of the zero-water washing return pipe, so there is a lack of corresponding filtering structure;

[0004] Secondly, if the return water pipe is filtered, if it is a conventional closed filter, then after long-term use, the filter material can only be replaced, which is inconvenient to clean the filtered impurities and the filtering efficiency is insufficient. Utility Model Content

[0005] The purpose of the utility model is to provide a filtering structure for zero-water-wash return water of a spinning machine. By arranging a return water trough, a curved filter screen 1, a curved filter screen 2, and a partition, the problems of lack of filtering function in the zero-water-wash return water pipeline of the spinning machine, inconvenience in cleaning impurities in the conventional filtering structure, and insufficient filtering efficiency are solved.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a filtering structure for zero-water washing return water of a spinning machine, comprising a return water tank, a curved filter screen 1 and a curved filter screen 2, a vertically arranged partition is fixed in the return water tank, and a grid hole distributed in a rectangular array is penetrated through the upper part of the partition, and a return water pipe is also penetrated and fixed at the bottom of the return water tank;

[0008] The bottom of the return water tank above the return water pipe is covered with a curved filter screen 2, and the bottom of the return water tank outside the curved filter screen 2 is also covered with a curved filter screen 1;

[0009] A connecting rope is fixed between the lower curved surface of the curved filter screen 1 and the center of the upper curved surface of the curved filter screen 2, a ring edge 1 is fixed to the outer edge of the curved filter screen 1, and a sealing gasket 1 is embedded and fixed at the bottom of the ring edge 1;

[0010] A second ring edge is fixed to the outer edge of the second curved filter screen, and a second sealing pad is embedded and fixed to the bottom of the second ring edge; elastic rods are fixed in a ring array at the center of the lower curved surface of the second curved filter screen.

[0011] Furthermore, the bottom of the sealing gasket 1 exceeds and is lower than the bottom surface of the ring edge 1, and the bottom surface of the sealing gasket 1 contacts the inner bottom surface of the return water tank.

[0012] Furthermore, the bottom of the second sealing gasket exceeds and is lower than the bottom surface of the second ring edge, and the bottom surface of the second sealing gasket contacts the inner bottom surface of the return water tank, and the bottom surfaces of the second sealing gasket and the first sealing gasket are flush.

[0013] Furthermore, the surface of the curved filter screen 1 is provided with filter holes 1 distributed at equal intervals, the surface of the curved filter screen 2 is provided with filter holes 2 distributed at equal intervals, and the aperture of the filter holes 2 is smaller than the aperture of the filter holes 1.

[0014] Furthermore, extrusion heads are fixed to the mutually opposite sides of the lower parts of the three elastic rods, the lower parts of the elastic rods and the extrusion heads are both extended into the return water pipe, and the extrusion heads contact the inner wall of the return water pipe.

[0015] Furthermore, a straight rod is fixed at the center of an upper curved surface of the curved filter, and a spherical end is fixed at the top of the straight rod.

[0016] The utility model has the following beneficial effects:

[0017] The utility model solves the problem that the zero-water-washing return water pipeline of the spinning machine lacks filtering function by arranging a return water trough, a curved filter screen 1, a curved filter screen 2 and a partition. The conventional zero-water-washing return water pipeline of the spinning machine is directly connected to the spinning machine. The utility model arranges a return water trough under the spinning machine, and no longer directly inputs the return water pipe. It is filtered once through the grille holes on the partition in the return water trough, and then filtered twice through the curved filter screen 1, and then filtered three times through the curved filter screen 2. After filtration, it enters the return water pipe to filter out debris and dirt, and prevents the return water pipe from being blocked. The curved filter screen 1 and the curved filter screen 2 are curved surfaces. When water flows through, the dirt is blocked outside the filter holes 1 and 2. Compared with the flat filter screen, the curved filter screen can increase the filtering area, effectively block debris and dirt from entering the return water pipe, and is more conducive to the sanitation of the zero-water-washing pipeline. PVC material is used to prevent acidic water corrosion.

[0018] The utility model solves the problem that the conventional filtering structure is inconvenient to clean impurities and has insufficient filtering efficiency by arranging a return trough, a curved filter screen 1, a curved filter screen 2 and a partition; the grille holes, the curved filter screen 1 and the curved filter screen 2 on the partition are used for filtering to achieve multi-stage filtration, the inner diameters of the grille holes, the filter holes 1 and the filter holes 2 are gradually reduced to achieve multi-stage filtering in sequence, and secondly, the curved filter screen 1 and the curved filter screen 2 can be easily disassembled to facilitate cleaning of impurities on the surface of the filter.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0031] See also Figure 1-8 As shown, the utility model is a filtering structure for zero-water washing return water of a spinning machine, comprising a return water tank 1, a curved filter screen 1 2 and a curved filter screen 2 3, a vertically arranged partition 101 is fixed in the return water tank 1, and a grid hole 1011 distributed in a rectangular array is penetrated through the upper part of the partition 101, and a return water pipe 102 is also penetrated and fixed at the bottom of the return water tank 1;

[0032] The return water of the spinning machine is injected into the return water tank 1 from the side of the partition 101 away from the return water pipe 102, and first passes through the grille holes 1011 for primary filtration to filter out larger debris and dirt, and then enters the return water tank 1 on the side of the partition 101 close to the return water pipe 102;

[0033] The bottom of the return tank 1 above the return pipe 102 is covered with a curved filter screen 2 3, and the bottom of the return tank 1 outside the curved filter screen 2 3 is also covered with a curved filter screen 1 2;

[0034] The water flow entering the upper part of the return pipe 102 is first filtered through the curved filter screen 1 2 for secondary filtration, and then filtered through the curved filter screen 2 3 for tertiary filtration;

[0035] A connecting rope 304 is fixed between the lower curved surface of the curved filter 1 2 and the center of the upper curved surface of the curved filter 2 3 , a ring edge 201 is fixed to the outer edge of the curved filter 1 2 , and a sealing gasket 203 is embedded and fixed at the bottom of the ring edge 201 ;

[0036] The outer edge of the curved filter screen 2 3 is fixed with a ring edge 2 301, and the bottom of the ring edge 2 301 is embedded with a sealing gasket 2 303; the center of the lower curved surface of the curved filter screen 2 3 is fixed with elastic rods 305 in a ring array;

[0037] The bottom of the sealing gasket 1 203 exceeds and is lower than the bottom surface of the ring edge 1 201, and the bottom surface of the sealing gasket 1 203 contacts the inner bottom surface of the return water tank 1; the bottom of the sealing gasket 2 303 exceeds and is lower than the bottom surface of the ring edge 2 301, and the bottom surface of the sealing gasket 2 303 contacts the inner bottom surface of the return water tank 1, and the bottom surfaces of the sealing gasket 2 303 and the sealing gasket 1 203 are flush;

[0038] The curved filter screen 2 has an increased area through the ring edge 201, which can more conveniently carry the filtered debris and facilitate subsequent cleaning. At the same time, it contacts the return water tank 1 through the sealing pad 203 to maintain a certain sealing and adsorption, and prevent the debris from passing through the gap between the ring edge 201 and the return water tank 1.

[0039] Similarly, the curved filter screen 2 3 also increases its area through the ring edge 2 301, making it more convenient to carry the filtered impurities and to clean up the subsequent impurities, and then contacts the return water tank 1 through the sealing gasket 2 303, maintaining the sealing and adsorbing contact with the return water tank 1, preventing debris from passing through the gap between the ring edge 2 301 and the return water tank 1, thereby ensuring the filtering efficiency; the bottom surfaces of the sealing gasket 1 203 and the sealing gasket 2 303 both extend out of the corresponding filter screen bottom and contact the return water tank 1.

[0040] The surface of the curved filter screen 1 2 is provided with filter holes 1 202 which are distributed at equal intervals, and the surface of the curved filter screen 2 3 is provided with filter holes 2 302 which are distributed at equal intervals, and the aperture of the filter holes 2 302 is smaller than the aperture of the filter holes 1 202;

[0041] The apertures of the filter hole 1 202 and the filter hole 2 302 are gradually reduced, so that filtering processing with increasing accuracy can be achieved.

[0042] An extrusion head 3051 is fixed to the side of the lower part of the three elastic rods 305 that are away from each other. The lower part of the elastic rod 305 and the extrusion head 3051 are both extended into the return pipe 102, and the extrusion head 3051 contacts the inner wall of the return pipe 102; hold all the elastic rods 305, insert the lower part of the elastic rod 305 and the extrusion head 3051 into the return pipe 102, then release them, and press down the curved filter screen 2 3 to make it contact the bottom of the return tank 1, and complete the installation of the curved filter screen 2 3. The elastic force of the elastic rod 305 will abut against the return pipe 102, thereby ensuring the fixation of the curved filter screen 2 3.

[0043] A straight rod 204 is fixed at the center of the curved surface on the curved filter 1 2, and a spherical end 2041 is fixed on the top of the straight rod 204; hold the spherical end 2041 to pull the straight rod 204, pull up the curved filter 1 2, and then pull up the curved filter 2 3 through the connecting rope 304, so as to remove the curved filter 1 2 and the curved filter 2 3, so as to facilitate the cleaning of the filtered impurities.

[0044] The specific working principle of the utility model is as follows: first, a return water tank 1 is set under the spinning machine, and the return water pipe 102 is no longer directly input. When installing the curved filter screen 1 2 and the curved filter screen 2 3, all elastic rods 305 are held, and the lower part of the elastic rod 305 and the extrusion head 3051 are inserted into the return water pipe 102, and then loosened, and the curved filter screen 2 3 is pressed down, so that the sealing gasket 2 303 at the bottom thereof contacts the bottom of the return water tank 1, and the installation of the curved filter screen 2 3 is completed, and then the curved filter screen 1 2 is covered to the outside of the curved filter screen 2 3, and the sealing gasket 2 303 contacts the bottom of the return water tank 1 at the same time. After the installation of the curved filter screen 23 is completed, the return water of the spinning machine is first injected into the return water tank 1 from the side of the partition 101 away from the return water pipe 102 until the liquid level is higher than the grille hole 1011. At this time, the return water first passes through the grille hole 1011 for primary filtration treatment to filter out larger debris and dirt, and then enters the return water tank 1 on the side of the partition 101 close to the return water pipe 102, and then passes through the filter hole 202 on the curved filter screen 2 for secondary filtration, and then passes through the filter hole 202 on the curved filter screen 23 for tertiary filtration, and finally enters the return water pipe 102.
