Description

Technical Field

[0001] The utility model belongs to the technical field of acrylic fiber fabrics, in particular to a dyeing and chemical material device for acrylic fiber fabrics. Background Art

[0002] Acrylic fiber, also known as polyacrylonitrile fiber, refers to the production of synthetic fibers with acrylonitrile as the main raw material. It has the advantages of being soft, bulky, easy to dye, bright in color, light-resistant, antibacterial, and insect-resistant. It can be spun purely or blended with natural fibers according to different application requirements. Its textiles are widely used in clothing, decoration, industry and other fields. In the process of production and processing of acrylic fiber, it is necessary to dye the processed acrylic fiber to improve the color richness of acrylic fabrics. Before dyeing, it is often necessary to use a chemical device to treat the dye with a chemical material, so that the dye raw material with a higher concentration is treated and diluted to the specified liquid volume and concentration to ensure the dyeing efficiency of acrylic fiber. However, it still has the following disadvantages in actual use:

[0003] The utility model with the publication number CN220149872U discloses an energy-saving chemical material device for fabric dyeing, wherein a connecting groove is provided inside the chemical material barrel body, a closing block is slidably connected inside the connecting groove, the closing block is connected to the connecting groove through a first compression spring, a filter is slidably connected to one end of the connecting groove away from the closing block, a connecting rod is fixedly connected inside the chemical material barrel body, and a support rod is rotatably connected to one end of the connecting rod away from the chemical material barrel body, a receiving groove is provided inside the support rod, a support member is slidably connected inside the receiving groove, and a second compression spring is fixedly connected to the support member extending to the receiving groove. When the dye raw material is chemically treated by the chemical material device, the dye raw material and a certain amount of water are usually directly introduced into the device for treatment, but most dyes often have high requirements on the temperature of water when chemically treated, and some dyes are easily hydrolyzed at high temperature, and it is necessary to use water, reagents and dye raw materials at a certain temperature to mix and adjust to a slurry state, and then introduce a certain amount of water at a certain temperature to dissolve and dilute the dye, and finally add cold water to reach a specified concentration of the dye, which is relatively cumbersome, time-consuming and labor-intensive.

[0004] During the dyeing process, solid dye raw materials may clump. During the stirring process, the dye moves with the flow of the solvent, and the volume of the device is usually large to facilitate the processing of a large amount of dye at one time. When the amount of solvent is large, it is difficult to quickly break up the dye raw materials, which reduces the dyeing speed. Utility Model Content

[0005] The utility model aims to provide a dyeing chemical device for acrylic fiber fabrics. Through a chemical barrel, a sealing top cover and a temperature treatment barrel, the utility model solves the problem that different dye raw materials have different operation modes and different requirements on water temperature during the chemical process, and the device is difficult to control more accurately. In the process of stirring the solvent and the dye raw material, due to the large amount of solvent and the large volume of the device, it is difficult to quickly dissolve the dye and the solvent and mix them evenly.

[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 dyeing device for acrylic fiber fabric, comprising a dyeing barrel, a sealing top cover and a temperature treatment barrel, wherein a first filter screen is fixedly connected to the bottom of the dyeing barrel, a sealing top cover is fixedly connected to the top of the dyeing barrel, a second filter screen is arranged at the bottom of the sealing top cover, a stirring motor is fixedly connected to the top of the sealing top cover, a temperature treatment barrel is fixedly connected to the top of the sealing top cover, and a material passing barrel is fixedly connected to the inside of the temperature treatment barrel;

[0008] During the chemical process, the second filter and the first filter can limit the dye raw material, so that the undissolved dye raw material is located between the first filter and the second filter, reducing the moving space of the dye raw material, so that the dye raw material can collide and disperse with the first filter and the second filter for many times, thereby improving the dispersion and dissolution efficiency of the dye raw material. The stirring motor can drive the solvent and the dye raw material to mix and stir in the chemical barrel, thereby improving the automation degree of the device. The temperature of the solvent to be used in the next step can be controlled by the temperature treatment barrel, and the temperature of the dye in the chemical barrel can be adjusted in time by adding a solvent of a certain temperature, thereby ensuring that the dye is at the optimal temperature for chemical processing, ensuring chemical processing efficiency, and avoiding hydrolysis or decomposition of the dye raw material.

[0009] Furthermore, a feed pipe is welded through the top of the outer peripheral surface of the chemical barrel, a discharge hopper is welded through the bottom of the chemical barrel, a discharge pipe is welded through the center of the bottom of the discharge hopper, a support frame is clamped and fixed around the bottom of the discharge hopper, and the second filter screen is attached to the inner wall of the chemical barrel;

[0010] The first filter can limit the position of the dye raw material, preventing the undissolved dye raw material particles from being discharged directly through the discharge pipe, reducing the moving space of the dye raw material in the chemical barrel, and allowing the dye raw material to collide and disperse with the first filter and the second filter multiple times, thereby improving the dispersion and dissolution efficiency of the dye raw material.

[0011] Furthermore, a stirring rod is clamped at the bottom of the stirring motor, and a first stirring blade and a second stirring blade are welded and fixed to the outer peripheral surface of the stirring rod from top to bottom, and the stirring rod penetrates and is inserted into the sealing top cover, the second filter screen and the top of the first filter screen, the first stirring blade is attached to the top of the first filter screen, the second stirring blade is attached to the bottom of the first filter screen, and the first stirring blade and the second stirring blade are attached to the inner wall of the chemical barrel;

[0012] The stirring motor can drive the first stirring blade and the second stirring blade to rotate, so as to mix and stir the dye raw material and the solvent, so that the dye raw material and the solvent are dissolved and mixed. At the same time, the first stirring blade and the second stirring blade can scrape off the dye attached to the inner wall of the chemical barrel and the surface of the first filter screen, so as to further ensure that the dye raw material and the solvent are mixed evenly.

[0013] Furthermore, a lifting cylinder is clamped on the top of the sealing top cover, a telescopic tube is slidably clamped on the bottom of the lifting cylinder, the second filter is clamped on the bottom of the telescopic tube, the telescopic tube is inserted through the top of the sealing top cover, and the second filter is suspended on the top of the first stirring blade;

[0014] The lifting cylinder can drive the second filter to move up and down. According to the amount of different dye raw materials, the moving space of the dye raw materials can be limited, thereby improving the flexibility of use, further ensuring the rapid digestion of the dye raw materials, and further limiting the moving space of the dye raw materials as the digestion time goes by until the second filter is attached to the upper side of the first stirring blade. At the same time, the up and down movement of the second filter can scrape off the raw materials attached to the inner wall of the digestion barrel, thereby ensuring that the dye raw materials and the solvent are evenly mixed.

[0015] Furthermore, a feed hopper is welded through the top of the feed barrel, a heating plate is clamped and fixed on the outer circumference of the feed barrel, a connecting pipe is welded through the bottom of the outer circumference of the feed barrel, and the other end of the connecting pipe is clamped and connected to the top of the sealing top cover;

[0016] The heating plate can heat the solvent poured into the material barrel to make the solvent reach the most suitable material temperature. The temperature treatment barrel can keep the inside of the material barrel warm so that the solvent is at a suitable temperature for a long time, which makes it easy to pour the solvent into the material barrel in time when needed.

[0017] Furthermore, a drainage pipe is welded through the top of the outer circumference of the temperature treatment barrel, a water inlet pipe is welded through the bottom of the outer circumference of the temperature treatment barrel, the feed hopper is connected to the top of the temperature treatment barrel, and the connecting pipe is connected to the outer circumference of the temperature treatment barrel;

[0018] Temperature sensing components can be set in the material passing barrel and the chemical barrel. When the solvent temperature in the material passing barrel is higher than the suitable processing temperature of the dye raw material, the solvent can be quickly cooled down by passing cold water into the temperature processing barrel. When it is monitored that the temperature of the dye raw material and the solvent in the chemical barrel is higher or lower than the suitable temperature range, a certain amount of solvent at the suitable temperature in the material passing barrel can be quickly poured into the chemical barrel to regulate the temperature in the chemical barrel. The operation is simple and convenient, and the dye chemicalization efficiency is guaranteed.

[0019] The utility model has the following beneficial effects:

[0020] The utility model solves the problem that when dye raw materials are chemically processed by a chemical device, the dye raw materials and a certain amount of water are usually directly introduced into the device for processing, but most dyes often have high requirements on the temperature of water when they are chemically processed, and some dyes are easily hydrolyzed at high temperatures, and it is necessary to use water at a certain temperature, reagents and dye raw materials to mix and adjust to a slurry state, and then introduce a certain amount of water at a certain temperature to dissolve and dilute the dye, and finally add cold water to achieve a specified concentration of the dye, and the operation is cumbersome, time-consuming and labor-intensive. When the dye is chemically processed, the solvent is poured into the feeding barrel, and cold water is introduced into the temperature treatment barrel through a heating plate or a temperature treatment barrel to make the solvent at a suitable chemical temperature required by the dye in the chemical barrel. When the solvent needs to be added or when the temperature in the chemical barrel deviates from the suitable temperature range, a certain amount of solvent with a suitable temperature in the feeding barrel is poured into the chemical barrel, and the temperature in the chemical barrel is regulated. The operation is simple and convenient, and the chemical efficiency of the dye is guaranteed.

[0021] The utility model solves the problem that solid dye raw materials may agglomerate during the dye chemical process by providing a chemical barrel and a sealing top cover. During the stirring process, the dye moves with the flow of the solvent, and the volume of the device is usually large so as to process a large amount of dye at one time. When the amount of solvent is large, it is difficult to quickly break up the dye raw materials, thereby reducing the dye chemical speed. After the dye raw materials are poured into the chemical barrel, the second filter screen is controlled by the lifting cylinder to move downward to a suitable position, thereby reducing the moving space of the dye raw materials in the chemical barrel. When the dye raw materials and the solvent are stirred by the first stirring blade and the second stirring blade driven by the stirring motor, the dye raw materials can collide and disperse with the first filter screen and the second filter screen for many times, thereby improving the dispersion and dissolution efficiency of the dye raw materials, and the moving space of the dye raw materials can be further limited as the chemical time passes, until the second filter screen is attached to the upper side of the first stirring blade.

[0030] See also Figure 1-5 As shown, the utility model is a dyeing device for acrylic fiber fabrics, comprising a dyeing barrel 1, a sealing top cover 2 and a temperature treatment barrel 3, a first filter screen 101 is fixedly connected to the bottom of the dyeing barrel 1, a sealing top cover 2 is fixedly connected to the top of the dyeing barrel 1, a second filter screen 201 is arranged at the bottom of the sealing top cover 2, a stirring motor 202 is fixedly connected to the top of the sealing top cover 2, a temperature treatment barrel 3 is fixedly connected to the top of the sealing top cover 2, and a material passing barrel 303 is fixedly connected to the inside of the temperature treatment barrel 3;

[0031] The solvent is poured into the feed barrel 303 and heated by the heating plate 306 to make the solvent reach a suitable temperature. When the temperature is higher than the threshold, cold water is passed into the temperature treatment barrel 3 to cool the solvent so that the solvent is always at a suitable temperature required for the dye chemical material. The dye raw material is poured into the chemical material barrel 1 through the feed pipe 102, and the lifting cylinder 206 is controlled according to the amount of the dye raw material to drive the second filter screen 201 to move downward to a suitable height, thereby reducing the moving space of the dye raw material in the chemical material barrel 1. A certain amount of solvent with a suitable temperature is poured into the chemical material barrel 1, and the stirring motor 202 is started to drive the first stirring blade 2 04. The second stirring blade 205 rotates to stir the dye raw material and the solvent, so that the dye raw material collides and disperses with the first filter 101 and the second filter 201 for many times, and as the dyeing time goes by, the second filter 201 is further controlled to move downward to limit the moving space of the dye raw material, until the second filter 201 is attached to the upper side of the first stirring blade 204. When it is necessary to increase the solvent or when the temperature in the chemical barrel 1 deviates from the appropriate temperature range, a certain amount of solvent at an appropriate temperature in the feed barrel 303 is poured into the chemical barrel 1, and the temperature in the chemical barrel 1 is regulated until the dye chemicalization is completed.

[0032] Among them Figure 1-3 As shown, a feed pipe 102 is welded through the top of the outer peripheral surface of the chemical barrel 1, a discharge hopper 103 is welded through the bottom of the chemical barrel 1, a discharge pipe 105 is welded through the center of the bottom of the discharge hopper 103, a support frame 104 is clamped and fixed around the bottom of the discharge hopper 103, and the second filter screen 201 is attached to the inner wall of the chemical barrel 1;

[0033] A specified amount of dye raw material is poured into the chemical barrel 1 through the feed pipe 102, and the dye raw material is restricted by the first filter 101 to prevent the undissolved dye raw material particles from being discharged directly through the discharge pipe 105. After the chemical reaction is completed, the discharge pipe 105 is opened to discharge the dye.

[0034] Among them Figure 1 , 2As shown in , 4, a stirring rod 203 is clamped at the bottom of the stirring motor 202, and a first stirring blade 204 and a second stirring blade 205 are welded and fixed on the outer peripheral surface of the stirring rod 203 from top to bottom. The stirring rod 203 penetrates and is inserted into the sealing top cover 2, the second filter screen 201 and the top of the first filter screen 101. The first stirring blade 204 is attached to the top of the first filter screen 101, and the second stirring blade 205 is attached to the bottom of the first filter screen 101. The first stirring blade 204 and the second stirring blade 205 are attached to the inner wall of the chemical barrel 1, and a lifting cylinder 206 is clamped at the top of the sealing top cover 2. A telescopic tube 207 is slidably clamped at the bottom of the lifting cylinder 206. The second filter screen 201 is clamped at the bottom of the telescopic tube 207, and the telescopic tube 207 penetrates and is inserted into the top of the sealing top cover 2, and the second filter screen 201 is suspended from the top of the first stirring blade 204.

[0035] After the dye raw material is poured into the chemical barrel 1, the lifting cylinder 206 is controlled to drive the telescopic tube 207 to stretch, and further drive the second filter 201 to move downward to limit the moving space of the dye raw material. In the chemical process of the dye raw material, the stirring motor 202 drives the rotation of the stirring rod 203, and further drives the rotation of the first stirring blade 204 and the second stirring blade 205 to mix and stir the dye raw material and the solvent, and the dye raw material collides with the second filter 201 and the first filter 101 for many times during the movement, so that the dye raw material is broken up and dissolved and mixed with the solvent. As the chemical time goes by, the lifting cylinder 206 further drives the second filter 201 to move downward to limit the moving space of the dye raw material until the second filter 201 is attached to the upper side of the first stirring blade 204. At the same time, the movement of the second filter 201 scrapes off the raw material attached to the inner wall of the chemical barrel 1.

[0036] Among them Figure 1 , 2 As shown in , 5, a feed hopper 304 is welded through the top of the feed barrel 303, a heating plate 306 is fixedly connected to the outer circumference of the feed barrel 303, a connecting pipe 305 is welded through the bottom of the outer circumference of the feed barrel 303, and the other end of the connecting pipe 305 is welded through the top of the sealing top cover 2, a drain pipe 301 is welded through the top of the outer circumference of the temperature treatment barrel 3, a water inlet pipe 302 is welded through the bottom of the outer circumference of the temperature treatment barrel 3, the feed hopper 304 is welded through the top of the temperature treatment barrel 3, and the connecting pipe 305 is welded through the outer circumference of the temperature treatment barrel 3;

[0037] Before dyeing, a large amount of solvent is poured into the feed hopper 304, and the solvent entering the feed barrel 303 is heated by the heating plate 306 to make the solvent reach a suitable chemical temperature. After the temperature is higher than the suitable temperature range, cold water is passed into the temperature treatment barrel 3 through the water inlet pipe 302 to cool the solvent. When it is necessary to increase the solvent or when the temperature in the chemical barrel 1 deviates from the suitable temperature range, the connecting pipe 305 is opened to allow a certain amount of solvent to be poured into the chemical barrel 1 to regulate the temperature in the chemical barrel 1.

[0038] The specific working principle of the utility model is as follows: before dyeing, a large amount of solvent is poured into the feed hopper 304, the solvent entering the feed barrel 303 is heated by the heating plate 306 to make the solvent reach a suitable material temperature, and after the temperature is higher than the suitable temperature range, cold water is passed into the temperature treatment barrel 3 through the water inlet pipe 302 to cool the solvent, and a specified amount of dye raw material is poured into the material barrel 1 through the feed pipe 102, and the lifting cylinder 206 is controlled to drive the telescopic tube 207 to stretch, and further drive the second filter screen 201 to move downward to a suitable position, and the moving space of the dye raw material is limited, and the connecting pipe 305 is opened to allow a certain amount of solvent to be poured into the material barrel 1, and the stirring motor 202 drives the rotation of the stirring rod 203, and further drives the first stirring blade 204 and the second stirring blade 2 05 rotates to mix and stir the dye raw material and the solvent, and makes the dye raw material collide with the second filter screen 201 and the first filter screen 101 for many times during the movement, so that the dye raw material is broken up and dissolved and mixed with the solvent. As the chemical reaction time passes, the lifting cylinder 206 further drives the second filter screen 201 to move downward, and limits the moving space of the dye raw material until the second filter screen 201 is attached to the upper side of the first stirring blade 204. At the same time, the movement of the second filter screen 201 scrapes off the raw material attached to the inner wall of the chemical barrel 1. When it is necessary to increase the solvent or when the temperature in the chemical barrel 1 deviates from the appropriate temperature range, the connecting pipe 305 is opened to pour a certain amount of solvent into the chemical barrel 1, and the temperature in the chemical barrel 1 is regulated. After the chemical reaction is completed, the discharge pipe 105 is opened to discharge the dye.
