Description

Technical Field

[0002] Pre-shrinking refers to the process of physically reducing the shrinkage of fabrics after immersion in water. This is because some textile materials have a high shrinkage rate. To prevent garments from becoming missized after washing, fabrics are pre-shrunk before being made into garments. This pre-shrunk treatment eliminates the potential for shrinkage, and the resulting fabrics generally shrink less significantly after being processed into finished garments. However, the existing pre-shrinking process discharges large amounts of wash water, which also contains various impurities. This makes recycling this pre-shrunk water difficult and costly.

[0035] like Figure 1-2 A pre-shrinkage treatment water circulation system includes: a pre-shrinkage machine 1, a cooling pipe 2, a return pipe 3, a filter press 4, a filter tank 5, a filter mechanism 6 and a circulation pump 7;

[0036] The water outlet end of the cooling pipe 2 is connected to the water inlet end of the pre-shrinkage machine 1, the water outlet end of the pre-shrinkage machine 1 is connected to the water inlet end of the return pipe 3, and the water outlet end of the return pipe 3 is connected to the water inlet end of the filter press 4; the filter tank 5 is provided with a plurality of filter chambers 50 in sequence along the water flow direction; two adjacent filter chambers 50 are connected to each other; the water outlet end of the filter press 4 is connected to the filter chamber 50 arranged at the relatively front, and the filter chamber 50 arranged at the relatively rear is provided with the filtering mechanism 6, and the filter chamber 50 arranged at the rear is connected to the water inlet end of the cooling pipe 2; the circulating pump 7 is installed on the cooling pipe 2.

[0037] This solution provides a pre-shrinkage treatment water circulation system, which discharges the water in the filter chamber 50 in the filter tank 5 to the pre-shrinkage machine 1, and returns the water in the pre-shrinkage machine 1 to the filter chamber 50 for filtration using the filter press 4, and then filters it in the filter chamber 50 through the filter mechanism 6, thereby realizing the water circulation of the pre-shrinkage treatment and solving the problems of high water consumption and high recovery cost of the existing water circulation treatment system.

[0038] Specifically, the shrinking machine 1 is a well-known device that can increase the weft density and radial shrinkage of the fabric to a certain extent by utilizing the expansion and contraction deformation of the elastic blanket under suitable wet and hot conditions, thereby having a relaxed structure. When the fibers are mixed and swelled, the radial length is no longer shortened, which has the effect of significantly reducing the shrinkage rate of the finished product. In this solution, the water of the filter tank 5 is output to the shrinking machine 1 through the cooling pipe 2. The shrinking machine 1 receives the water filtered by the filter tank 5, performs pre-shrinkage treatment on the fabric, and then outputs the discharged water to the water inlet of the filter press 4 through the return pipe 3; the filter press 4 is a well-known mechanism, which has a filter plate, which can filter the water in the return pipe 3 through the filter plate, thereby removing particles and impurities (such as cotton fibers) in the water, and output the filtered water to the filter chamber 50 of the filter tank 5; wherein, the filter tank 5 is provided with a plurality of filter chambers 50 arranged in this order, and the two adjacent filter chambers 50 are connected, so it is only necessary to arrange the filter chambers 50 in the front. The filter chamber 50 is connected to the water outlet of the filter press 4, and the filter chamber 50 arranged at the rear is connected to the water inlet of the cooling pipe 2; in this way, when the water of the reflux pipe 3 is output to the filter chamber 50 in the front, the circulation pump 7 of the cooling pipe 2 can be started, and the water will be pumped to the cooling pipe 2 through the action of the circulation pump 7, so that the water passes through the filter mechanisms 6 of multiple filter chambers 50 in sequence, and the filter mechanisms 6 filter the output water of the filter press 4; since the number of filter chambers 50 can be multiple, different filter mechanisms 6 can be set for filter chambers 50 in different positions, so that impurities during the pre-shrinkage treatment can be filtered multiple times, thereby achieving a water purification function. Furthermore, the water in the cooling pipe 2 will continue to be output to the pre-shrinkage machine 1 for reuse under the action of the circulation pump 7, thereby achieving a water circulation function. In this way, the water after the pre-shrinkage treatment can be pressed and filtered, and the water can be purified and recycled, which can solve the problems of high water consumption and high recycling costs of the existing water circulation treatment system.

[0039] Optimally, it further includes: an active cooling mechanism 8;

[0040] The active cooling mechanism 8 includes: a cooling water tower 81, a cooling input pipe 82, a cooling output pipe 83 and a cooling pump 84;

[0041] The output end of the cooling water tower 81 is connected to the input end of the cooling input pipe 82, the output end of the cooling input pipe 82 is connected to the filter chamber 50, the input end of the cooling output pipe 83 is connected to the filter chamber 50, and the output end of the cooling output pipe 83 is connected to the input end of the cooling water tower 81; the cooling input pipe 82 is provided with the cooling pump 84.

[0042] Generally, during the output of the pre-shrink machine 1 to the filter press 4 and the filter tank 5, the output water can be indirectly cooled by air, and the air cools the pipeline and takes away the heat of the water in the pipeline; at the same time, the exposed openings and tank walls of the filter chamber 50 can directly or indirectly contact the water with the air, thereby achieving the cooling effect; and in the optimal embodiment, the water output by the pre-shrink machine 1 can be cooled by the cooling water tower 81; specifically, the cooling pump 84 is started, and the water in the filter chamber 50 is output to the cooling water tower 81 through the cooling input pipe 82. The water exchanges heat and mass with the air flowing through the cooling water tower 81, causing the water temperature to drop, and then the cooled water is output to the filter chamber 50 through the cooling output pipe 83, thereby achieving active cooling of the filter chamber 50.

[0043] Optimally, the filter tank 5 is provided with an upper vertical plate 51 and a lower vertical plate 52;

[0044] A plurality of lower vertical plates 52 and upper vertical plates 51 are alternately installed in the filter tank 5 and respectively abut against two opposing inner side walls of the filter tank 5. The upper vertical plates 51 and the lower vertical plates 52 are separated to form a filter opening 53, and the filter mechanism 6 is disposed in the filter opening 53. The upper end of the lower vertical plate 52 is lower than the upper end of the upper vertical plate 51, and an upper hollow opening 54 is formed between the upper end of the lower vertical plate 52 and the opening of the filter tank 5.

[0045] The lower end of the lower vertical plate 52 abuts against the bottom wall of the filter tank 5 , and a lower hollow opening 55 is formed between the lower end of the upper vertical plate 51 and the bottom wall of the filter tank 5 .

[0046] The upper vertical plate 51 and the lower vertical plate 52 are arranged in pairs, and a filter opening 53 is formed between the two. The upper vertical plate 51 is higher than the lower vertical plate 52, and the upper end of the lower vertical plate 52 is lower than the opening of the filter tank 5, thereby forming an upper hollow opening 54; the lower end of the upper vertical plate 51 and the bottom wall of the filter tank 5 form a lower hollow opening 55; in this way, when water needs to pass through multiple pairs of upper vertical plates 51 and lower vertical plates 52, the water will first pass through the upper hollow opening 54 above the lower vertical plate 52, then enter the filter mechanism 6 of both the upper vertical plate 51 and the lower vertical plate 52, and finally transfer through the lower hollow opening 55 below the upper vertical plate 51, thereby transferring to the next pair of upper vertical plates 51 and lower vertical plates 52; in this way, this scheme can control the flow direction of water only by the height of the upper vertical plate 51 and the lower vertical plate 52. The water must flow through the filter mechanism 6 between the two, so that multiple filter mechanisms 6 can be arranged at a low cost to improve the filtering efficiency.

[0047] Optimally, the upper vertical plate 51 is separated from one of the lower vertical plates 52 on one side to form the filter opening 53 , and the upper vertical plate 51 is separated from the other lower vertical plate 52 on the other side to form the filter cavity 50 ; the space of the filter cavity 50 is larger than the filter opening 53 .

[0048] The lower risers 52 and upper risers 51 are arranged alternately, so that the two faces of the upper risers 51 face different lower risers 52. Thus, one face of the upper riser 51 forms a filter cavity 50, while the other face of the upper riser 51 forms a filter opening 53. The filter cavities 50 and filter openings 53 are arranged alternately, and the space of the filter cavities 50 is larger than the filter openings 53, allowing them to accommodate more water and improve water storage capacity. The filter openings 53 only need to accommodate the filter mechanism 6. As a result, water first passes through the upper hollow opening 54 above the lower riser 52, then enters the filter mechanisms 6 of both the upper riser 51 and the lower riser 52, and finally enters one of the filter cavities 50 through the lower hollow opening 55 below the upper riser 51. This repeated filtration operation can improve filtration efficiency at a low cost.

[0049] Optimally, the filtering mechanism 6 includes: a PP cotton filter element 61;

[0050] The PP cotton filter element 61 is disposed in the filter opening 53 .

[0051] The PP cotton filter element 61 is mainly installed in the filter opening 53. Before each water passes through the filter cavity 50, it will first enter the PP cotton filter element 61. The PP cotton filter element 61 is a tubular filter element made of polyester fiber particles through heating, melting, spinning, pulling, and receiving forming. Therefore, the PP cotton filter element 61 can effectively remove impurities in the filtrate. When water passes through multiple PP cotton filter elements 61, the pre-shrinkage impurities are removed.

[0052] Optimally, the filtering mechanism 6 includes: an activated carbon filtering module 62;

[0053] The activated carbon filter module 62 is disposed in the rearmost portion of the filter chamber 50 .

[0054] The activated carbon filter module 62 is provided with activated carbon, which is mainly arranged in the filter chamber 50 at the rear. The solid surface of the activated carbon can be used to adsorb one or more substances in the water to achieve the purpose of purifying the water quality. The water can be purified when it is about to be discharged from the filter tank 5 to achieve the effect of removing impurities.

[0055] It can be optimized to further include: a filter element flushing mechanism 9;

[0056] The filter element flushing mechanism 9 includes: a filter element flushing pipe 91 and a filter element flushing valve 92;

[0057] The output end of the filter element flushing pipe 91 is connected to the multiple filter chambers 50; the input end of the filter element flushing pipe 91 is used to input tap water; the filter element flushing valve 92 is installed on the filter element flushing pipe 91.

[0058] After multiple uses, the PP cotton filter element 61 of this solution may have impurities on its surface or inside. Therefore, this solution provides a filter element flushing pipe 91 at the filter chamber 50, through which tap water can be input into the filter chamber 50. When the liquid level of the tap water rises and covers the PP cotton filter element 61, the PP cotton filter element 61 can be backwashed, and the impurities in the filter chamber 50 can be returned to the liquid phase, thereby achieving the effect of cleaning the filter chamber 50, the filter opening 53 and the filter mechanism 6.

[0059] Optimally, the filter tank 5 is provided with a tap water chamber 56 at the last position of the filter chamber 50, and the tap water chamber 56 is connected to the last filter chamber 50; the tap water chamber 56 is used to receive tap water; the tap water chamber 56 is connected to the water inlet end of the cooling pipe 2.

[0060] The tap water chamber 56 is located at the end of the filter chamber 50, meaning that water will eventually be discharged into the cooling pipe 2 through the tap water chamber 56. This may deplete the total water volume in the system, causing a decrease in the total water volume. To address this, the present solution provides a tap water chamber 56 at the end of the filter chamber 50. This chamber receives tap water through manual or automatic input and can deliver it to the cooling pipe 2 at the end of the filter chamber 50, ensuring that clean water is delivered directly to the cooling pipe 2. Furthermore, because the tap water chamber 56 is located at the end of the filter chamber 50, the water in this last filter chamber 50 has already undergone multiple layers of filtration, resulting in fewer impurities, which are unlikely to enter the tap water chamber 56.

[0061] A textile pre-shrinkage processing line is provided with the above-mentioned pre-shrinkage treatment water circulation system.

[0062] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
