Abstract
Description
Technical Field
[0001] This application relates to the field of textile dyeing technology, specifically to a soap-free dyeing apparatus. Background Technology
[0002] Soap-free washing refers to the process where textiles do not require soaping or color fixing after dyeing. This is achieved through improvements to the dyes used. Soap-free dyeing reduces the number of steps, the use of reagents, the cost of wastewater treatment, and water and electricity bills.
[0003] Soapless dyeing includes pretreatment, dyeing and posttreatment steps. This process is prone to generating floating matter, which is generally not easy to be discharged from the system through the drain pipe and is likely to remain in textiles and equipment, causing certain pollution to textiles and equipment. Utility Model Content
[0004] In order to improve the situation where floating matter generated during the pretreatment and posttreatment of textiles is not easily discharged from the system and tends to remain on the textiles and in the equipment, causing certain pollution to both the textiles and the equipment, this application proposes a soap-free dyeing apparatus to improve this situation, specifically adopting the following technical solution.
[0005] A soap-free dyeing apparatus includes a water supply pipe, a pretreatment device, a dyeing device, and a posttreatment device.
[0006] The pretreatment equipment includes a pretreatment container, a first overflow pipe, and multiple pretreatment liquid cylinders. The inlet end of the first overflow pipe is connected to the pretreatment container. The multiple pretreatment liquid cylinders are respectively connected to the pretreatment container. The staining equipment includes a staining container and multiple staining liquid cylinders respectively connected to the staining container. The posttreatment equipment includes a posttreatment container and a third overflow pipe. The inlet end of the third overflow pipe is connected to the posttreatment container.
[0007] The water supply pipes are respectively connected to the pretreatment container, the dyeing container, and the posttreatment container.
[0008] By adopting the above technical solution, after treating the textiles with the pretreatment solution, the pretreatment solution is drained. Then, clean water is continuously circulated into the pretreatment equipment to rinse the textiles. The water overflows through the first overflow pipe, carrying away a large amount of floating matter and reducing its residue, thus mitigating contamination of the textiles and pretreatment containers. After this overflow treatment, there is less floating matter residue on the textiles, improving dyeing efficiency and yield. During dyeing, due to the high cost of the dye solution, no overflow pipe is installed. During post-treatment, water can also be continuously circulated to discharge floating matter into the post-treatment container through the third overflow pipe, reducing the residue of floating matter in the textiles and post-treatment equipment.
[0009] A preferred embodiment of the soap-free dyeing apparatus is that the pretreatment equipment further includes a first rotary driver, a first turntable, a first sealing ring, and a first drain pipe.
[0010] The output shaft of the first rotary actuator passes through the pretreatment container and connects to the first turntable. The first turntable seamlessly abuts against the bottom surface of the pretreatment container via the first sealing ring.
[0011] The first drain pipe is connected to the bottom of the pretreatment container and connects the gap between the first turntable and the side wall of the pretreatment container. A first automatic valve is installed on the first drain pipe. The outlet end of the first overflow pipe is connected to the section of the first drain pipe located after the first automatic valve.
[0012] By adopting the above technical solution, the first rotary driver drives the first turntable, thereby driving the water and textiles in the pretreatment container to rotate, improving the pretreatment efficiency and the efficiency of discharging floating matter.
[0013] In a preferred embodiment of the soap-free dyeing apparatus, the upper surface of the first turntable has a shape that continuously descends from the center to the periphery. A first inner convex ring is fixed to the inner wall of the pretreatment container. The first turntable and the first inner convex ring are coaxially arranged. The upper surface of the first inner convex ring has a shape that continuously descends from the outer ring to the inner ring.
[0014] By adopting the above technical solution, during drainage, water can flow out from the gap between the first turntable and the first inner convex ring, and very little water remains in the pretreatment container.
[0015] A preferred embodiment of the soap-free dyeing apparatus is that the pretreatment equipment further includes a first heating coil, a first insulation jacket, and a first outer cylinder.
[0016] The first heating coil is wound around the outer periphery of the pretreatment container. The first insulation sleeve is wrapped around the first heating coil. The pretreatment container is mounted inside the first outer cylinder by a bracket. The stator of the first rotary actuator is fixed to the inner bottom surface of the first outer cylinder. The upper end of the first outer cylinder also inwardly wraps around the upper edge of the pretreatment container.
[0017] By adopting the above technical solution, the first heating coil heats the pretreatment container to heat the water and pretreatment liquid inside, thereby improving the pretreatment efficiency and cleaning efficiency.
[0018] In a preferred embodiment of the soap-free dyeing apparatus, the plurality of pretreatment liquid cylinders include an alkali liquid cylinder, an acid liquid cylinder, and a degreasing agent cylinder. The inlet end of the first overflow pipe is lower than all interfaces of the plurality of pretreatment liquid cylinders and the pretreatment container, as well as lower than the interfaces of the water supply pipe and the pretreatment container.
[0019] By adopting the above technical solution, the alkaline solution can remove lint, colloids, metal ions, etc., the degreasing agent removes grease from textiles, and the acid solution can neutralize the alkaline solution absorbed by the textiles. Overflow will not enter the water supply pipe or pretreatment container, thus preventing contamination.
[0020] A preferred embodiment of the soap-free dyeing apparatus is that the dyeing equipment further includes a second outer cylinder, a second heating coil, a second drain pipe, and a second automatic valve.
[0021] The dyeing container is installed inside the second outer cylinder. The second heating coil is wound around the outer wall of the dyeing container. The second drain pipe is connected to the bottom of the dyeing container. The second automatic valve is installed on the second drain pipe.
[0022] By adopting the above technical solution, the dyeing efficiency is improved by heating when textiles absorb dye.
[0023] A preferred embodiment of the soap-free dyeing apparatus includes a second rotary driver, a second turntable, and a second sealing ring. The output shaft of the second rotary driver passes through the dyeing container and is fixed to the second turntable. The second turntable is seamlessly abutted against the inner bottom surface of the dyeing container via the second sealing ring. The inner sidewall of the dyeing container has a second inner convex ring. The second inner convex ring surrounds the circumference of the second turntable. A second drain pipe connects the gap between the second inner convex ring and the second turntable.
[0024] By adopting the above technical solution, the dye solution is rotated during dyeing, thereby improving dyeing efficiency.
[0025] A preferred embodiment of this soap-free dyeing apparatus comprises multiple dye tanks, including a first color tank, a second color tank, a third color tank, and an auxiliary material tank. The first color tank contains a first color dye. The second color tank contains a second color dye. The third color tank contains a third color dye.
[0026] By adopting the above technical solution, dyes of different colors are placed in different dyeing tanks, reducing mixed contamination.
[0027] A preferred embodiment of the soap-free dyeing apparatus is that the post-treatment container includes a third outer cylinder, a third heating coil, a third drain pipe, a third automatic valve, a third rotary drive, a third turntable, and a third sealing ring.
[0028] The post-processing container is mounted inside the third outer cylinder via a bracket. The third heating coil is wound around the outer wall of the post-processing container. The output shaft of the third rotary actuator passes through the post-processing container to fix the third turntable. The third turntable seamlessly abuts against the inner bottom surface of the post-processing container via the third sealing ring. The third drain pipe is connected to the bottom of the post-processing container and connects the gap between the third turntable and the side wall of the post-processing container. The third automatic valve is mounted on the third drain pipe.
[0029] By adopting the above technical solution, during post-treatment, water is circulated, heated, and rotated to improve the efficiency of dissolving soluble substances and removing lint and floating matter. These impurities are discharged from the post-treatment container through overflow, reducing their contamination of textiles and the post-treatment container.
[0030] In a preferred embodiment of the soap-free dyeing apparatus, the upper end of the third overflow pipe is connected to the upper end of the post-treatment container, and the lower end of the third overflow pipe is connected to the section of the third drain pipe located after the third automatic valve. The inlet end of the third overflow pipe is lower than the interface between the water supply pipe and the post-treatment container.
[0031] By adopting the above technical solution, the overflow is not controlled by the third automatic valve and can overflow freely, and the overflow liquid does not contaminate the inlet water.
[0032] In summary, the soap-free dyeing apparatus of this application has the following beneficial effects: After pretreatment, the textiles are washed with clean water, which overflows from the first overflow pipe, carrying away a large amount of floating matter and reducing its residue, thus mitigating contamination of the textiles and pretreatment container. Similarly, during posttreatment, water can be continuously supplied, and floating matter is discharged from the posttreatment container through the third overflow pipe, further reducing its residue in the textiles and posttreatment equipment. These improvements mitigate the contamination of the textiles and apparatus caused by floating matter generated during both pretreatment and posttreatment processes. Attached Figure Description

[0038] The technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the following embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0039] like Figure 1 A soap-free dyeing apparatus includes a pretreatment device 1, a dyeing device 2, a posttreatment device 3, and a water supply pipe 4. The water supply pipe 4 is connected to the pretreatment device 1, the dyeing device 2, and the posttreatment device 3, respectively, and a solenoid valve is installed before each device to control the on / off of the water supply.
[0040] This soap-free washing process includes pretreatment, dyeing, and posttreatment. First, the textiles are placed in pretreatment equipment 1, where pretreatment solution is added to remove grease, lint, and sap, followed by rinsing with water. Then, the textiles are placed in dyeing equipment 2 to soak in dye solution for coloring. Finally, the textiles are placed in posttreatment equipment 3 to remove impurities with water. Heating and stirring can be used in all three steps to accelerate processing. The pretreatment and posttreatment rinsing processes can also remove floating matter through overflow. However, due to the high cost of dye solution, overflow is generally not performed.
[0041] like Figure 2The pretreatment device 1 includes a pretreatment container 101, a first heating coil 102, a first insulation jacket 103, a first outer cylinder 104, a first overflow pipe 105, a first drain pipe 106, a first rotary driver 107, a first turntable 108, and three pretreatment liquid cylinders 109.
[0042] The pretreatment container 101 can be a cylindrical body. A first heating coil 102 is wound around the outer wall of the pretreatment container 101 to heat the water or reagents inside, accelerating the reaction efficiency. A first insulating sleeve 103 can be insulating cotton, which wraps around the outside of the first heating coil 102. A first outer cylinder 104 is fitted over the pretreatment container 101, also wrapping the first heating coil 102, the first insulating sleeve 103, and the first overflow pipe 105 inside. Both the upper part of the first outer cylinder 104 and the upper part of the pretreatment container 101 are open. A bracket 110 is installed at the bottom of the pretreatment container 101, supporting it within the first outer cylinder 104. The upper edge of the first outer cylinder 104 also wraps inward to the upper edge of the pretreatment container 101, shielding the first heating coil 102, the insulating cotton, and the first overflow pipe 105 inside, and preventing foreign objects from falling into the cavity between the first outer cylinder 104 and the pretreatment container 101.
[0043] A first automatic valve 111 is installed on the first drain pipe 106. The first automatic valve 111 can be a solenoid valve. The first drain pipe 106 is connected to the bottom of the pretreatment container 101. The upper end of the first overflow pipe 105 is connected to the upper end of the pretreatment container 101, and the lower end of the first overflow pipe 105 is connected to the pipe section of the first drain pipe 106 located after the first automatic valve 111. That is, the opening and closing of the first overflow pipe 105 is not controlled by the first automatic valve 111.
[0044] The first rotary drive 107 can be a motor. The stator of the first rotary drive 107 is fixed to the inner bottom surface of the first outer cylinder 104. The output shaft of the first rotary drive 107 passes upward into the pretreatment container 101 and fixes the first turntable 108. The first turntable 108 is parallel to the inner bottom surface of the pretreatment container 101, and a first sealing ring 112 is installed between the first turntable 108 and the inner bottom surface of the pretreatment container 101. Thus, under the drive of the first rotary drive 107, the first turntable 108 always rotates in a sealed and close fit to the inner bottom surface of the pretreatment container 101, and water cannot penetrate to the output shaft of the first rotary drive 107.
[0045] The lower part of the side wall of the pretreatment container 101 has an integrally formed inwardly protruding first inner ring 1011. The first inner ring 1011 surrounds the periphery of the first turntable 108, and the two are coaxial and maintain a certain gap distance, for example, the gap width between the first inner ring 1011 and the first turntable 108 is 0.5~1cm. The inlet end of the first drain pipe 106 connects to the gap between the first inner ring 1011 and the first turntable 108 to facilitate drainage.
[0046] The upper surface of the first turntable 108 is higher in the middle and lower around the edges, gradually sloping downwards from the middle. The outer periphery of the first inner convex ring 1011 is higher and the inner periphery is lower, gradually sloping downwards from the outer periphery to the inner periphery. During drainage, water can collect in the gap between the first turntable 108 and the first inner convex ring 1011, and is thus collected by the first drain pipe 106 and discharged outside the device. The first drain pipe 106 can be connected to a waste liquid treatment device for environmentally friendly treatment of the waste liquid.
[0047] The three pretreatment liquid cylinders 109 can be alkali cylinders, acid cylinders, and degreasing agent cylinders, respectively containing alkali solution, acid solution, and degreasing agent. When pretreating textiles, the textiles can be placed in the pretreatment container 101, water, alkali solution, and degreasing agent can be introduced, the mixture can be heated, the liquid can be drained, then water can be introduced for overflow rinsing, then acid solution can be added to neutralize the residual alkali solution, and finally water can be introduced for overflow rinsing.
[0048] Three pretreatment liquid cylinders 109 are respectively connected to the first outer cylinder 104 via pipes and then to the pretreatment container 101. The connection ports of these three pipes and the pretreatment container 101 are all higher than the connection port of the first overflow pipe 105 and the pretreatment container 101, so that overflowing floating matter will not contaminate the connection ports of the pretreatment liquid cylinders 109 and the pretreatment container 101. Each of the three pipes is equipped with a pump and a solenoid valve. The pump can draw pretreatment liquid, and the solenoid valve controls the opening and closing of the pipes.
[0049] A branch pipe from the water supply pipe 4 passes through the first outer cylinder 104 and connects to the pretreatment container 101. A solenoid valve is installed on this branch pipe. The connection port between this branch pipe and the pretreatment container 101 is also higher than the connection port between the first overflow pipe 105 and the pretreatment container 101, so that the overflowing floating matter will not contaminate the connection port between the water supply pipe 4 and the pretreatment container 101.
[0050] like Figure 3The dyeing equipment 2 is structurally similar to the pretreatment equipment 1, except that the dyeing equipment 2 does not have an overflow pipe and has four dye liquor cylinders 201, which replace the three pretreatment liquor cylinders 109 of the pretreatment equipment 1. The four dye liquor cylinders 201 are a first color cylinder, a second color cylinder, a third color cylinder, and an auxiliary material cylinder. The first color cylinder contains a first-color dye, such as yellow pigment. The second color cylinder contains a second-color dye, such as blue pigment. The third color cylinder contains a third-color dye, such as red pigment. The auxiliary material cylinder contains auxiliary materials. The dyes are not mixed; generally, only one type of dye is introduced at a time. The inclusion of four dye liquor cylinders 201 in the dyeing equipment 2 is only one embodiment of the dyeing equipment 2. In addition, the dyeing equipment 2 may also contain more or fewer than four dye liquor cylinders 201; for example, the dyeing equipment 2 may have three or five dye liquor cylinders 201.
[0051] Specifically, in addition to the four dyeing cylinders 201, the dyeing equipment 2 also includes a dyeing container 202, a second outer cylinder 203, a second heating coil 204, a second insulation jacket 205, a second drain pipe 206, a second automatic valve 207, a second rotary driver 208, a second turntable 209, and a second sealing ring 210.
[0052] The second outer cylinder 203 is fitted over the dyeing container 202. The dyeing container 202 is fixed inside the second outer cylinder 203 by the bottom bracket 110. The upper edge of the second outer cylinder 203 wraps horizontally inward to the upper edge of the dyeing container 202.
[0053] Four dyeing cylinders 201 are connected to the dyeing container 202 via pipes passing through the second outer cylinder 203. Each of the four pipes is equipped with a pump and a solenoid valve. A branch pipe of the water supply pipe 4 is also connected to the dyeing container 202, and a solenoid valve is installed on this branch pipe.
[0054] The second heating coil 204 is wound around the outer wall of the dyeing container 202, and the second insulation sleeve 205 is wrapped around the outside of the second heating coil 204. The dyeing container 202 can be a cylinder with an open top. The second rotary drive 208 can be a motor, with its stator fixed to the inner bottom surface of the second outer cylinder 203, and its shaft passing upward through the bottom surface of the dyeing container 202. The passage can be non-contact or connected by a bearing. After passing through the dyeing container 202, the shaft is fixedly connected to the bottom surface of the second turntable 209. The bottom surface of the second turntable 209 and the bottom surface of the dyeing container 202 are rotatably sealed by a second sealing ring 210, which surrounds the shaft to prevent water from seeping into the shaft and stator. The upper surface of the second turntable 209 is higher in the middle and lower around the edges, so that water can flow from the middle to the edges during drainage. The lower end of the inner wall of the corresponding dyeing container 202 has a second inner convex ring 2021 that protrudes inward. The upper surface of the second inner convex ring 2021 slopes downward from the outside to the inside, allowing water to flow from the outer ring to the inner ring during drainage. The inner ring of the second inner convex ring 2021 surrounds the outer circumference of the second turntable 209, with a gap of 0.5~1cm between them. The inlet end of the second drain pipe 206 connects to this gap. This allows water to collect in the gap between the second inner convex ring 2021 and the second turntable 209 during drainage and then seep downward into the second drain pipe 206. A second automatic valve 207 is provided on the second drain pipe 206. The second automatic valve 207 can be a solenoid valve, which can automatically drain the liquid through a control system.
[0055] During dyeing, pre-treated textiles can be placed into dyeing container 202, water, a dye and auxiliary materials of a certain color can be introduced, heating can be performed, and the second rotary drive 208 can be started to accelerate the dyeing of textiles.
[0056] like Figure 4 The post-treatment device 3 has a similar structure to the pre-treatment device 1, except that the post-treatment device 3 does not include the pre-treatment liquid cylinder 109. Specifically, the post-treatment device 3 includes a post-treatment container 301, a third overflow pipe 302, a third outer cylinder 303, a third heating coil 304, a third insulation jacket 305, a third drain pipe 306, a third automatic valve 307, a third rotary actuator 308, a third turntable 309, and a third sealing ring 310.
[0057] The third heating coil 304 is wound around the outer wall of the post-processing container 301, and the third insulation sleeve 305 wraps around the third heating coil 304. The third drain pipe 306 is connected to the bottom of the post-processing container 301. The third automatic valve 307 is installed on the third drain pipe 306. The upper end of the third overflow pipe 302 is connected to the upper end of the post-processing container 301, and the lower end of the third overflow pipe 302 is connected to the section of the third drain pipe 306 located after the third automatic valve 307, so that the third automatic valve 307 can control the opening and closing of the drain pipe, but does not control the opening and closing of the third overflow pipe 302.
[0058] The third outer cylinder 303 surrounds the post-treatment container 301, the third heating coil 304, the third insulation jacket 305, the third overflow pipe 302, and the third automatic valve 307. A portion of the third drain pipe 306 is outside the third outer cylinder 303, and another portion extends out of the third outer cylinder 303. The post-treatment container 301 is supported within the third outer cylinder 303 by a bracket 110 mounted on its outer bottom.
[0059] The third rotary drive 308 can be an electric motor, with its stator fixed to the inner bottom surface of the third outer cylinder 303 and its rotor passing upward through the post-processing container 301 to fix the third turntable 309. The lower surface of the third turntable 309 is always rotatably and sealingly connected to the inner bottom surface of the post-processing container 301 through the third sealing ring 310.
[0060] The lower end of the side wall of the post-treatment container 301 has an inwardly protruding third inner ring 3011, which surrounds the outer periphery of the third turntable 309. The upper surface of the third inner ring 3011 gradually slopes downward from the outer ring to the inner ring. The upper surface of the third turntable 309 gradually slopes downward from the center to the periphery. This structure allows water to be guided into the gap between the third turntable 309 and the third inner ring 3011 when the post-treatment device 3 is draining, and a third drain pipe 306 is installed below this gap, so that the drained water is guided to the third drain pipe 306 and flows out.
[0061] A branch pipe from the water supply pipe 4 passes through the third outer cylinder 303 and connects to the post-treatment container 301. The interface between this branch pipe and the post-treatment container 301 is higher than the interface between the third overflow pipe 302 and the post-treatment container 301, so that floating matter will not contaminate the interface between the water supply pipe 4 and the post-treatment container 301. A solenoid valve is installed on this branch pipe.
[0062] When performing post-treatment on textiles, the dyed textiles are first placed into the post-treatment container 301, water is introduced into the post-treatment container 301, heating and the third rotary drive 308 are turned on to perform overflow cleaning on the dyed textiles. After cleaning, the third automatic valve 307 is opened to drain the water. The above cleaning process can be repeated to complete the soap-free dyeing process of textiles.
[0063] The soap-free dyeing apparatus of this application is equipped with overflow pipes in the pretreatment equipment 1 and the posttreatment equipment 3, which can overflow and clean, thereby efficiently removing floating matter generated in the process, improving the cleanliness and dyeing quality of textiles, and also improving the cleanliness of the pretreatment equipment 1, the dyeing equipment 2 and the posttreatment equipment 3.
[0064] Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
