Description

Technical Field

[0001] This utility model relates to the field of high-temperature dyeing vat technology, and specifically discloses a high-temperature dyeing vat with dye liquor recycling function. Background Technology

[0002] In the textile printing and dyeing industry, high-temperature dyeing vats are key equipment for dyeing fabrics. As the industry continues to expand, the treatment of dye liquor during the dyeing process has become a significant factor restricting enterprise development and the achievement of environmental goals. Traditional high-temperature dyeing vats discharge large amounts of dye liquor directly after use, resulting in a huge waste of water resources and dyes, significantly increasing production costs for enterprises. Furthermore, the residual dyes, auxiliaries, and other pollutants in the wastewater cause serious damage to the ecological environment, leading to increasingly stringent environmental regulations.

[0003] Some companies have attempted to address these issues using dye liquor recycling technology, but existing recycling systems have several shortcomings. For example, the dye liquor filtration process is not precise enough; relying solely on simple filters is insufficient to effectively remove impurities, residual dye, and odors from the dye liquor, leading to a decline in the quality of the recycled dye liquor and affecting subsequent dyeing results. Furthermore, during the dye liquor recycling process, the flow rate and pressure lack effective monitoring, making it impossible to precisely adjust them according to different dyeing processes.

[0004] Furthermore, the lack of an effective pretreatment and mixing step before recycling the dye liquor means that the newly added dyes and auxiliaries cannot fully blend with the recycled dye liquor, affecting the uniformity and stability of the dyeing process.

[0005] Furthermore, the existing equipment's filter components are inconvenient to clean and maintain, and their filtration efficiency significantly decreases after long-term use. Therefore, a high-temperature dyeing vat with dye liquor recycling function is needed to solve these problems. Utility Model Content

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0027] Please see Figure 1-4A high-temperature dyeing vat with dye liquor recycling function includes a vat body 1. A heating pipe is installed between the inner and outer walls of the vat body 1. The outer wall of the vat body 1 is connected to a pretreatment cylinder 3 through a connecting pipe 2. A filtration mechanism and a premixing mechanism are arranged on the right side of the pretreatment cylinder 3.

[0028] The filtration mechanism is fixedly connected to the support ring 15 on the inner wall of the pretreatment cylinder 3. The upper end of the support ring 15 abuts against the activated carbon filter screen 13. A first filter screen 12 is arranged above the activated carbon filter screen 13, and a second filter screen 11 is arranged above the first filter screen 12. A rotating rod 8 is arranged on the right side of the pretreatment cylinder 3. The lower ends of the rotating rod 8, the second filter screen 11, and the first filter screen 12 are all fixedly connected to the internal threaded cylinder 9. The upper ends of the second filter screen 11, the first filter screen 12, and the activated carbon filter screen 13 are all fixedly connected to the threaded rod 10 that is threaded to the adjacent internal threaded cylinder 9. The lower end of the outer wall of the pretreatment cylinder 3 is connected to the circulation pipe 4, and the other end of the circulation pipe 4 is connected to the upper end of the outer wall of the cylinder 1.

[0029] A drive mechanism is provided on the outer wall of the pretreatment cylinder 3:

[0030] The premixing mechanism includes a motor 16 installed at the bottom of the pretreatment cylinder 3. The output end of the motor 16 passes through the pretreatment cylinder 3 and is fixedly connected to a cross stirring rod 17.

[0031] In this embodiment: the filter mechanism is moved to the inside of the pretreatment cylinder 3 by the drive mechanism, and the dye liquor passes through the second filter screen 11 and the first filter screen 12 to filter the impurities in the dye liquor; then the dye liquor passes through the activated carbon filter screen 13 to remove the residual dye and odor in the dye liquor by utilizing the adsorption characteristics of activated carbon, thus completing the filtration and purification process of the dye liquor; then the filter mechanism is moved to the outside of the pretreatment cylinder 3 by the drive mechanism.

[0032] If new dye needs to be added to the purified dye solution, the dye is added to the upper port of the pretreatment cylinder 3, and the motor 16 installed at the bottom of the pretreatment cylinder 3 is started. Its output end drives the cross stirring rod 17 to rotate, which fully stirs and mixes the dye solution, ensuring that the dye solution composition is uniform, improving the uniformity and stability of subsequent dyeing. The pretreated dye solution flows out from the circulation pipe 4 at the lower end of the outer wall of the pretreatment cylinder 3. Under the action of the liquid pump, it is transported back to the upper end of the outer wall of the cylinder 1 along the circulation pipe 4, realizing the recycling of the dye solution.

[0033] If the filter screen needs to be cleaned or replaced, the first filter screen 12, the second filter screen 11 and the activated carbon filter screen 13 can be unscrewed in sequence to facilitate the operator to clean or replace the filter screen. After cleaning, the filter screen can be reinstalled in the reverse order to ensure the continuous and efficient operation of the filtration mechanism.

[0034] As a technical optimization of this utility model, the driving mechanism includes a support plate 5 fixedly connected to the outer wall of the pretreatment cylinder 3. An electric push rod 6 is installed at the lower end of the support plate 5. The output end of the electric push rod 6 passes through the support plate 5 and is fixedly connected to a U-shaped frame 7. A second motor 18 is installed inside the U-shaped frame 7, and its output end is fixedly connected to the rotating rod 8.

[0035] In this embodiment: the U-shaped frame 7 can be driven to move up and down by the electric push rod 6, and the rotating rod 8 can be driven to rotate by the second motor 18.

[0036] As a technical optimization of this utility model, a sealing ring 14 is fixedly connected to the lower end of the activated carbon filter 13, and an annular groove is opened at the upper end of the support ring 15.

[0037] In this embodiment, the connection between the activated carbon filter 13 and the support ring 15 can be sealed by the sealing ring 14 abutting against the inside of the annular groove.

[0038] As a technical optimization of this utility model, the first filter screen 12 is a coarse filter screen and the second filter screen 11 is a fine filter screen.

[0039] In this embodiment: the first filter screen 12 is a coarse filter screen, which can filter large particulate impurities, and the fine filter screen can filter small particulate impurities. The combination of the two can improve the filtration effect.

[0040] As a technical optimization of this utility model, a liquid pump is installed on the outer wall of both the connecting pipe 2 and the circulation pipe 4.

[0041] In this embodiment: the pump on the outer wall of the connecting pipe 2 can pump the dye inside the cylinder 1 to the pretreatment cylinder 3, and the pump on the outer wall of the circulation pipe 4 can pump the filtered dye inside the pretreatment cylinder 3 to the cylinder 1.

[0042] As a technical optimization of this utility model, an observation window is installed through the outer wall of the pretreatment cylinder 3.

[0043] In this embodiment, the observation window allows for convenient observation of the dye level and dyeing process inside the pretreatment cylinder 3.

[0044] As a technical optimization of this utility model, the diameters of the first filter screen 12, the second filter screen 11, and the activated carbon filter screen 13 are all the same as the inner diameter of the pretreatment cylinder 3.

[0045] In this embodiment, the diameters of the first filter screen 12, the second filter screen 11, and the activated carbon filter screen 13 are all the same as the inner diameter of the pretreatment cylinder 3. This design ensures that when the dye liquor flows in the pretreatment cylinder 3, all the dye liquor will come into contact with the filter screen. There is no situation where the dye liquor passes directly through the gap between the filter screen and the inner wall of the pretreatment cylinder 3 without being filtered, thus avoiding the formation of filtration dead corners and achieving comprehensive and deep purification of the dye liquor.

[0046] The working principle and usage process of this utility model are as follows: When the high-temperature dyeing tank with dye liquor recycling function is working, after dyeing is completed, the dye liquor in the tank 1 flows into the pretreatment cylinder 3 through the connecting pipe 2. At this time, the filter mechanism is moved to the inside of the pretreatment cylinder 3 by the drive mechanism. The dye liquor first passes through the second filter screen 11. Since the second filter screen 11 is a fine filter screen, it can intercept smaller particles of impurities in the dye liquor. Then the dye liquor flows through the first filter screen 12 (coarse filter screen), which further filters out larger particles of impurities. Subsequently, the dye liquor passes through the activated carbon filter screen 13. The activated carbon filter screen 13 uses the adsorption characteristics of activated carbon to remove residual dye and odor in the dye liquor, completing the filtration and purification process of the dye liquor. The filter mechanism is then moved to the outside of the pretreatment cylinder 3 by the drive mechanism.

[0047] If new dye needs to be added to the purified dye solution, the dye is added to the upper port of the pretreatment cylinder 3, and the motor 16 installed at the bottom of the pretreatment cylinder 3 is started. Its output end drives the cross stirring rod 17 to rotate, which fully stirs and mixes the dye solution, ensuring that the dye solution composition is uniform, improving the uniformity and stability of subsequent dyeing. The pretreated dye solution flows out from the circulation pipe 4 at the lower end of the outer wall of the pretreatment cylinder 3. Under the action of the liquid pump, it is transported back to the upper end of the outer wall of the cylinder 1 along the circulation pipe 4, realizing the recycling of the dye solution.

[0048] If the filter screen needs to be cleaned or replaced, since the lower ends of the rotating rod 8, the second filter screen 11 and the first filter screen 12 are all fixedly connected to the internal threaded cylinder 9, and the upper ends of the second filter screen 11, the first filter screen 12 and the activated carbon filter screen 13 are all fixedly connected to the threaded rod 10 that is threaded to the adjacent internal threaded cylinder 9, the first filter screen 12, the second filter screen 11 and the activated carbon filter screen 13 can be unscrewed in sequence during the upward movement of the rotating rod 8, making it convenient for the operator to clean or replace the filter screen. After cleaning, the filter screen can be reinstalled in its original position by reversing the operation to ensure the continuous and efficient operation of the filtration mechanism.
