Description
Technical Field
[0001] A foam wetting device for the post-treatment process of denim fabric belongs to the technical field of denim fabric production and processing. Background Art
[0002] In the post-treatment process of the denim fabric processing flow in the prior art, generally the following several processes are included: singeing - desizing - washing - scouring - drying - waterproof treatment. Among them, in the washing process, the traditional washing method is to realize a certain proportion of auxiliary agent solution through a washing machine. This method consumes a large amount of auxiliary agents and raw water, is prone to waste, and at the same time, a large amount of energy is also consumed in the subsequent drying process.
[0003] In order to overcome the problem of large consumption of the traditional washing method, a technical solution using foam for washing has also emerged on the market. In this technical solution, a certain proportion of auxiliary agent solution is sent into a foam generator to generate foam, and then the foam is sent to a foam scraper through a pipeline. When the two sides of the denim fabric pass through two foam scrapers respectively, the denim fabric is wetted to replace the washing of the denim fabric.
[0004] The method of using foam to wash denim fabric, compared with the traditional washing method, greatly reduces the waste of raw materials. However, it is found in actual operation that since the wetting effect of foam on the fabric is slightly worse than that of the traditional washing method, during the washing process with foam, the foam is prone to overflow from both ends of the fabric. In the prior art, after the foam overflows, it is generally directly discharged. Therefore, the traditional foam washing method will also cause waste of raw materials to a certain extent, and the random discharge of foam will also cause environmental pollution to a certain extent. Summary of the Utility Model

[0006] The technical solution adopted by the present utility model to solve its technical problems is: the foam wetting device for the post-treatment process of denim fabric includes a plurality of foam scraping mechanisms. A foam generator is connected to each foam scraping mechanism. Foam output ports are respectively arranged at the end parts of each foam scraping mechanism.

It is characterized in that: a collection pool is provided, the collection pool is located below the foam scraping mechanism, and a pumping mechanism is connected to the collection pool.

[0024] Figures 1 to 4 This is the best embodiment of the present invention. The following will further explain the present invention in conjunction with the attached Figures 1 to 4 diagrams.
[0025] As Figure 1 shown, a foam wetting device for the post-treatment process of denim fabric includes a main frame (not shown in the figure). An upper bubble scraping mechanism 3 and a lower bubble scraping mechanism 4 are fixed through the main frame. Multiple fabric guiding rollers 2 are also fixed through the main frame. While the fabric 1 (denim fabric) sequentially bypasses each fabric guiding roller 2, it passes through the upper bubble scraping mechanism 3 and the lower bubble scraping mechanism 4. When the fabric 1 passes through the upper bubble scraping mechanism 3 and the lower bubble scraping mechanism 4, the upper surface of the fabric 1 contacts the lower surface of the lower bubble scraping mechanism 4, and the lower surface of the fabric 1 contacts the upper surface of the upper bubble scraping mechanism 3. The upper surface of the upper bubble scraping mechanism 3 and the lower surface of the lower bubble scraping mechanism 4 respectively output foam to jointly perform a water washing operation on the fabric 1.
[0026] A collection pool 5 is arranged below the upper bubble scraping mechanism 3 and the lower bubble scraping mechanism 4. Since foam continuously outputs from the upper surface of the upper bubble scraping mechanism 3 and the lower surface of the lower bubble scraping mechanism 4, part of the foam output from the upper bubble scraping mechanism 3 and the lower bubble scraping mechanism 4 is absorbed by the fabric 1, and part of the foam overflows from the ends of the upper bubble scraping mechanism 3 and the lower bubble scraping mechanism 4 and falls into the collection pool 5.
[0027] A defoaming pump 7 is arranged on the ground. The inlet of the defoaming pump 7 is connected to the bottom of the collection pool 5 through a pipeline, and the outlet of the defoaming pump 7 returns to the stock solution tank 8 through a pipeline. Since the defoaming pump 7 itself has a defoaming function, after the defoaming pump 7 pumps out the foam in the collection pool 5, it pumps the auxiliary solution back into the stock solution tank 8 to achieve the recovery of the foam.
[0028] At least one foam generator 6 is provided on the ground or within the main frame. Preferably, multiple foam generators 6 corresponding to the upper foam scraping mechanism 3 and the lower foam scraping mechanism 4 are respectively provided. After the additive solution in the stock solution tank 8 is fed into the foam generator 6 (by a pump), foam is formed, and the foam is further fed into the corresponding foam scraping mechanism (the upper foam scraping mechanism 3 or the lower foam scraping mechanism 4) through a pipeline.
[0029] The upper foam scraping mechanism 3 and the lower foam scraping mechanism 4 have the same structure, and the difference lies in the opposite arrangement directions. As Figures 2 to 3 shown, both the upper foam scraping mechanism 3 and the lower foam scraping mechanism 4 include a foam scraper 9. A fixed platform 11 is provided at one end of the foam scraper 9, and the length of the fixed platform 11 is greater than the length of the foam scraper 9. The fixed platform 11 is fixed to the end of the foam scraper 9 along the length direction of the foam scraper 9. Multiple reinforcing plates 10 are provided between the fixed platform 11 and the foam scraper 9 to improve the stability through the multiple reinforcing plates 10. An output part 12 is vertically provided on the surface of the fixed platform 11. The output part 12 is in the shape of a long strip equal in length to the fixed platform 11 and is fixed in the middle of the fixed platform 11.
[0030] One end of the foam scraper 9 away from the fixed platform 11 is an arc surface, and the foam output from the foam generator 6 is fed into the foam scraper 9 from the apex of the arc. Since the foam diffuses along an arc path after entering the foam scraper 9, it can diffuse more evenly to both sides and spread to the output part 12.
[0031] Combined with Figure 4 , the foam scraper 9 is a hollow structure, one end of which is open. The fixed platform 11 is fixed at the open end of the foam scraper 9, and the output part 12 is fixed at the center of the fixed platform 11. An output port equal in length to itself is provided in the middle of the output part 12, and the output port penetrates the fixed platform 11 and communicates with the inner cavity of the foam scraper 9.
[0032] Collection boxes 13 are respectively provided at the ends of the upper foam scraping mechanism 3 and the lower foam scraping mechanism 4. The collection boxes 13 are respectively provided at both ends of the foam scraper 9 in the upper foam scraping mechanism 3 and the lower foam scraping mechanism 4. An extension part is formed inside the collection box 13, and the extension parts of the two ends of the collection box 13 extend towards the inside of the foam scraper 9. Since the length of the fixed platform 11 is greater than the length of the foam scraper 9, the extension parts of the two ends of the collection box 13 extend inwards to the edge of the foam scraper 9.
[0033] The specific working process and working principle are as follows:
[0034] The additive solution prepared from additives and raw water in the stock solution tank 8 is sent into the foam generator 6. The additive solution forms bubbles in the foam generator 6 and is sent through a pipeline into the bubble scraper 9 in the corresponding upper bubble scraping mechanism 3 or lower bubble scraping mechanism 4. After the foam enters the bubble scraper 9, it extends along the inner cavity of the bubble scraper 9 from one side of the arc surface to the other side. After reaching the fixed table 11, it is output from the output port at the center of the output part 12.
[0035] While the fabric 1 bypasses each fabric guide roller 2 in turn, it passes by the upper bubble scraping mechanism 3 and the lower bubble scraping mechanism 4. When the fabric 1 passes by the upper bubble scraping mechanism 3 and the lower bubble scraping mechanism 4, the upper surface of the fabric 1 contacts the lower surface of the lower bubble scraping mechanism 4, and the lower surface of the fabric 1 contacts the upper surface of the upper bubble scraping mechanism 3. At this time, the output parts 12 at the upper surface of the upper bubble scraping mechanism 3 and the lower surface of the lower bubble scraping mechanism 4 respectively output foam, and jointly perform a water washing operation on the fabric 1.
[0036] A collection pool 5 is arranged below the upper bubble scraping mechanism 3 and the lower bubble scraping mechanism 4. Since the foam continuously outputs from the upper surface of the upper bubble scraping mechanism 3 and the lower surface of the lower bubble scraping mechanism 4, a part of the foam output from the upper bubble scraping mechanism 3 and the lower bubble scraping mechanism 4 is absorbed by the fabric 1, and another part overflows from the ends of the upper bubble scraping mechanism 3 and the lower bubble scraping mechanism 4. The overflowed foam is first collected by the collection box 13. An opening is provided at the bottom of the collection box 13, and finally it uniformly falls into the collection pool 5.
[0037] An antifoaming pump 7 is arranged on the ground. The inlet of the antifoaming pump 7 is connected to the bottom of the collection pool 5 through a pipeline, and the outlet of the antifoaming pump 7 returns to the stock solution tank 8 through a pipeline. Since the antifoaming pump 7 itself has an antifoaming function, after the antifoaming pump 7 pumps out the foam in the collection pool 5, it pumps the additive solution back into the stock solution tank 8, realizing the recycling of the foam.
[0038] The above is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution content of the present invention still belong to the protection scope of the technical solution of the present invention.
