Description

Technical Field

[0001] The invention relates to the field of dyeing and finishing auxiliary agent processing, and in particular to a constant temperature treatment device and process for dyeing and finishing auxiliary agents. Background Art

[0002] Dyeing and finishing auxiliaries refer to auxiliaries used in the process of dyeing and finishing textiles into fabrics. In textile processing, cotton and its blended fabrics can be treated under low temperature conditions to obtain good degreasing and dewaxing effects. In this process, low-temperature refining agents are needed. Low-temperature refining agents are a type of dyeing and finishing auxiliaries. At present, the treatment device for low-temperature refining agents usually uses a heating element to directly heat the treatment chamber, which has the problem of too intense heating reaction to be difficult to control.

[0003] Chinese patent CN219731337U discloses a constant temperature treatment device for low-temperature refining agent, comprising: a machine base; a heating mechanism, the heating mechanism comprising an outer barrel fixed in the machine base, and a heater embedded in the inner wall of the outer barrel, the inner side of the outer barrel is provided with a water tank for placing water, the inner side of the water tank is provided with a temperature sensor; the heater is used to heat the water in the water tank; a processing mechanism, the processing mechanism comprising an inner barrel fixed in the water tank, a wheel plate provided at the bottom of the inner side of the inner barrel, and a motor provided on the outer side of the inner barrel; the motor drives the wheel plate to rotate inside the inner barrel.

[0004] The above scheme adopts the water bath heating method to ensure that there will be no uncontrollable problems during the heating reaction and the constant temperature effect is guaranteed. However, when preparing the low-temperature refining agent, water bath heating also has disadvantages, that is, the water in the heating kettle of the traditional water bath heating basically does not flow, and in the heating process, the water flow temperature close to the low-temperature refining agent in the mixed state is low, while the water flow temperature away from the low-temperature refining agent in the mixed state is high, so that water temperature stratification occurs, which results in that the water temperature cannot be well transferred to the low-temperature refining agent in the mixed state, and the heat transfer efficiency is low. At the same time, when the water bath method is used, after the preparation of the low-temperature refining agent is completed, the vessel containing the low-temperature refining agent needs to be taken out of the heating kettle, so the processing efficiency is low. Summary of the invention

[0005] In view of the above problems, a constant temperature treatment equipment and process for dyeing and finishing auxiliaries are provided. A separating ring is arranged in the annular cavity between the outer shell and the heating kettle to form a first circulation cavity and a second circulation cavity, and a circulation unit is arranged between the first circulation cavity and the second circulation cavity. At the same time, the volume of the first circulation cavity is made smaller than the volume of the second circulation cavity, thereby avoiding the water temperature stratification phenomenon that occurs when using a water bath for heating, and allowing the flowing water to have enough time to be heated by the heater, thereby improving the heat transfer efficiency.

[0006] In order to solve the problems of the prior art, the present invention provides a constant temperature treatment device for dyeing and finishing auxiliaries, comprising a shell and a heater sleeved on the outer periphery of the shell; The outer shell is a cylindrical structure, and a heating kettle is arranged inside the outer shell. An annular cavity is present between the outer wall of the heating kettle and the inner wall of the outer shell. A separating ring is arranged on the annular cavity. The separating ring is fixedly arranged at the bottom of the outer shell. The separating ring separates the annular gap into a first circulation cavity and a second circulation cavity along the radial direction of the outer shell. The first circulation cavity is located on the inner ring side of the separating ring, and the second circulation cavity is located on the outer ring side of the separating ring. A circulation unit connecting the first circulation cavity and the second circulation cavity is arranged at the bottom of the outer shell. Clean water is stored in the annular cavity, and the water level of the clean water is higher than the separating ring. The circulation unit draws the clean water in the second circulation cavity into the first circulation cavity. The volume of the first circulation cavity is smaller than that of the second circulation cavity.

[0007] Preferably, a first thermometer and a second thermometer are arranged in the first circulation chamber from top to bottom along the vertical direction. The first thermometer and the second thermometer are both arranged on the inner ring wall of the separation ring. The first thermometer and the second thermometer are used to measure the temperature of the water flow in the first circulation chamber. The separation ring is made of thermal insulation material.

[0008] The water temperature measured by the first thermometer is the first temperature, and the water temperature measured by the second thermometer is the second temperature. There is a temperature difference between the first temperature and the second temperature. A rated temperature difference threshold is preset for the temperature difference. When the temperature difference is less than the rated temperature difference threshold, the power of the circulation unit is increased, and when the temperature difference is greater than the rated temperature difference threshold, the power of the circulation unit is reduced; The water flow temperature in the first circulation chamber is preset with a working water temperature threshold, the rated temperature difference threshold is less than the working water temperature threshold, the working water temperature threshold has a maximum water temperature and a minimum water temperature, the first temperature monitored by the first thermometer is greater than the minimum water temperature, and the second temperature monitored by the second thermometer is less than the maximum water temperature. When the temperature difference between the first temperature and the second temperature is within the rated temperature difference threshold, if the first temperature is less than the minimum water temperature, the power of the circulation unit remains unchanged and the heater increases the power; if the second temperature is greater than the maximum water temperature, the power of the circulation unit remains unchanged and the heater reduces the power.

[0009] Preferably, the circulation unit includes a circulation pipe connecting the bottom of the first circulation chamber and the bottom of the second circulation chamber. A water pump is provided on the circulation pipe. The water pump draws the water flow in the second circulation chamber into the first circulation chamber through the circulation pipe. An inlet is provided at the connection between the circulation pipe and the first circulation chamber. The inlet is a funnel-shaped structure, and a spoiler blade is rotatably provided in the inlet.

[0010] Preferably, a stirring unit is arranged in the outer shell, and the stirring unit includes a stirring shaft which is rotatably arranged on the upper part of the outer shell along the axis of the outer shell, and the stirring shaft extends from the upper part of the heating kettle to the inner part of the heating kettle along the axis of the outer shell, and a discharge port is provided at the bottom of the heating kettle. The heating kettle located in the outer shell moves in the outer shell along the vertical direction, and the moving path of the outer shell includes a highest position and a lowest position. When the outer shell is at the highest position, the bottom of the stirring shaft extends to the discharge port and blocks the discharge port, thereby forming a closed working chamber in the heating kettle. When the outer shell is at the lowest position, the bottom of the stirring shaft slides out from the discharge port.

[0011] Preferably, a plurality of stirring rods are evenly arranged on the side wall of the stirring shaft around the axis of the stirring shaft, a sleeve is sleeved on the stirring rod along the extension direction of the stirring rod, the sleeve is slidably matched with the stirring rod, and a first scraper is fixedly arranged at one end of the sleeve away from the stirring shaft.

[0012] Preferably, a sliding groove is provided on the side wall of the stirring shaft along the extension direction of the stirring shaft, and a second scraper is slidably arranged in the sliding groove along the extension direction of the sliding groove. When the heating kettle is in the highest position, the bottom of the second scraper contacts the bottom of the heating kettle. The second scraper rotates under the drive of the stirring shaft and forms a sweeping area, which completely covers the bottom of the heating kettle. When the heating kettle is in the lowest position, the bottom of the second scraper is separated from the bottom of the heating kettle.

[0013] Preferably, a lifting unit for driving the heating kettle to move in a vertical direction is provided at the upper part of the heating kettle, the lifting unit includes an extension ring fixedly sleeved on the periphery of the heating kettle, a fixing frame is provided at the lower part of the extension ring, the fixing frame is fixedly provided on the inner wall of the outer shell, a threaded rod is provided on the extension ring along the vertical direction, the threaded rod is threadedly matched with the extension ring, two ends of the threaded rod are respectively rotatably matched with the fixing frame and the outer shell, a guide rod is provided on one side of the threaded rod parallel to the extension direction of the threaded rod, two ends of the guide rod are respectively fixedly connected with the fixing frame and the upper part of the outer shell, and a second rotation driver for driving the threaded rod to rotate is provided at the upper end of the threaded rod.

[0014] The present invention also relates to a constant temperature treatment process for dyeing and finishing auxiliaries, using a constant temperature treatment device for dyeing and finishing auxiliaries, and the specific preparation steps are as follows: S1. Add deionized water and isohexylene glycol into a stirring tank and stir to mix evenly; S2. Then, continue stirring and add isomeric tridecanol polyoxyethylene ether, fatty acid methyl ester ethoxylate, ABS and penetrant JFC in sequence. After the addition is completed, continue stirring for 5-20 minutes to complete the preparation.

[0015] Preferably, the specific formula ratio of dyeing and finishing auxiliaries is as follows: the ratio of fatty acid methyl ester ethoxylate is 20%-25%, the ratio of isomeric tridecyl alcohol polyoxyethylene ether is 5%-10%, the ratio of ABS is 1%-5%, the ratio of penetrant JFC is 5%-15%, the ratio of isohexanediol is 5%-10%, and the ratio of deionized water is 50%-60%.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. Before preparation, various raw materials need to be put into the heating kettle in sequence. A stirring unit is provided in the heating kettle. When the raw materials are put into the heating kettle in sequence, the stirring unit in the heating kettle starts to stir and mix the raw materials in the heating kettle. At the same time, the heater provided on the outer shell is started, and the heater transfers heat to the second circulation chamber through the outer shell, so that the clean water in the second circulation chamber can be heated. While the stirring unit stirs the raw materials in the heating kettle, the circulation unit is also started synchronously, and the circulation unit draws the water flow in the second circulation chamber into the first circulation chamber. The circulation unit injects the water flow from the bottom of the first circulation chamber into the first circulation chamber, so that the water in the first circulation chamber directly in contact with the heating kettle flows from bottom to top in the vertical direction, avoiding the occurrence of water temperature stratification around the heating kettle. This is because after the circulation unit injects the heated water into the first circulation chamber, the water in the upper layer of the first circulation chamber passes over the upper part of the separation ring and enters the second circulation chamber. It is worth noting that the volume of the first circulation chamber is smaller than that of the second circulation chamber, and both the first circulation chamber and the second circulation chamber are annular structures, so the annular diameter of the first circulation chamber is smaller than the annular diameter of the second circulation chamber. When the circulation unit is started, the amount of water drawn from the second circulation chamber by the circulation unit is equal to the amount of water injected into the first circulation chamber, so that the water flow rate in the first circulation chamber is greater than the water flow rate in the second circulation chamber. The faster the water flow rate in the first circulation chamber, the less likely the water in the first circulation chamber will be stratified by water temperature, and the slower the water flow in the second circulation chamber, the water flow in the second circulation chamber can be heated by the heater for a longer time, ensuring the heating effect of the heater, thus avoiding the water temperature stratification phenomenon that occurs when using a water bath for heating, and allowing the flowing water to have enough time to be heated by the heater, thereby improving the heat transfer efficiency.

[0017] 2. The water temperature of the flowing water in the first circulation chamber is monitored by setting a first thermometer and a second thermometer, and a rated temperature difference threshold is preset for the temperature difference between the first temperature and the second temperature. When the temperature difference is less than the rated temperature difference threshold, the power of the circulation unit is increased, and when the temperature difference is greater than the rated temperature difference threshold, the power of the circulation unit is reduced, so that the temperature in the first circulation chamber is within a constant temperature range.

[0029] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] Reference Figure 1-Figure 3 : A constant temperature treatment equipment for dyeing and finishing auxiliaries, comprising an outer shell 1 and a heater 2 sleeved on the outer periphery of the outer shell 1; the outer shell 1 is a cylindrical structure, a heating kettle 3 is arranged in the outer shell 1, an annular cavity is present between the outer wall of the heating kettle 3 and the inner wall of the outer shell 1, a separator ring 11 is arranged on the annular cavity, the separator ring 11 is fixedly arranged at the bottom of the outer shell 1, the separator ring 11 divides the annular gap into a first circulation cavity 12 and a second circulation cavity 13 along the radial direction of the outer shell 1, the first circulation cavity 12 is located on the inner ring side of the separator ring 11, and the second circulation cavity 13 is located on the outer ring side of the separator ring 11, a circulation unit 4 connecting the first circulation cavity 12 and the second circulation cavity 13 is arranged at the bottom of the outer shell 1, clean water is stored in the annular cavity, the water level of the clean water is higher than the separator ring 11, the circulation unit 4 draws the clean water in the second circulation cavity 13 into the first circulation cavity 12, and the volume of the first circulation cavity 12 is smaller than the volume of the second circulation cavity 13.

[0031] Dyeing and finishing auxiliaries include low-temperature refining agents, etc. Here, low-temperature refining agents are taken as an example. When preparing low-temperature refining agents, it is necessary to heat the low-temperature refining agents in a mixed state. However, the heating of the traditional heating kettle 3 is relatively intense, and the heating is not easy to control and cannot be maintained in a stable constant temperature range. Therefore, a water bath heating method is used to heat the mixed low-temperature refining agent. However, the water in the traditional water bath heating method is in a static state, and even if the water flows, the direction of the water flow is not controllable. In this way, the temperature of the water close to the heating kettle 3 is lower, and the temperature of the water far away from the heating kettle 3 is higher. This is because the water directly in contact with the heating kettle 3 transfers its own heat to the heating kettle 3, while the water far away from the heating kettle 3 cannot transfer heat to the heating kettle 3. This causes the water temperature to be stratified during the water bath, resulting in reduced heat transfer efficiency.

[0032] In order to avoid the above situation, the structure between the shell 1 and the heating kettle 3 is further optimized. The specific structure and working principle are as follows: a feed pipe 5 is provided between the heating kettle 3 and the shell 1. The feed pipe 5 is preferably a corrugated structure, and the raw materials are injected into the heating kettle 3 through the feed pipe 5. Before preparation, various preparation raw materials need to be put into the heating kettle 3 in sequence. The order of putting the raw materials into the heating kettle 3 will be introduced below. A stirring unit 6 is provided in the heating kettle 3. When the raw materials are put into the heating kettle 3 in sequence, the stirring unit 6 in the heating kettle 3 starts to stir and mix the raw materials in the heating kettle 3. At the same time, the heater 2 provided on the shell 1 is started, and the heater 2 transfers heat to the second circulation chamber 13 through the shell 1, so that the clean water in the second circulation chamber 13 can be heated. While the stirring unit 6 is stirring the raw materials in the heating kettle 3, the circulation unit 4 is also started synchronously. The circulation unit 4 draws the water flow in the second circulation chamber 13 into the first circulation chamber 12, and the circulation unit 4 injects the water flow into the first circulation chamber 12 from the bottom of the first circulation chamber 12. In this way, the water in the first circulation chamber 12 flows from bottom to top in a vertical direction, avoiding the occurrence of water temperature stratification around the heating kettle 3. This is because after the circulation unit 4 injects the heated water into the first circulation chamber 12, the water in the upper layer of the first circulation chamber 12 passes over the upper part of the separation ring 11 and enters the second circulation chamber 13. It is worth noting that the volume of the first circulation chamber 12 is smaller than that of the second circulation chamber 13, and both the first circulation chamber 12 and the second circulation chamber 13 are annular structures, so the ring diameter of the first circulation chamber 12 is smaller than the ring diameter of the second circulation chamber 13. When the circulation unit 4 is started, the amount of water drawn from the second circulation chamber 13 by the circulation unit 4 is equal to the amount of water injected into the first circulation chamber 12, so that the water flow rate in the first circulation chamber 12 is greater than the water flow rate in the second circulation chamber 13. The faster the water flow rate in the first circulation chamber 12, the less likely the water in the first circulation chamber 12 will be stratified by water temperature, and the slower the water flow in the second circulation chamber 13, the water flow in the second circulation chamber 13 can be heated by the heater 2 for a longer time, ensuring the heating effect of the heater 2, thus avoiding the water temperature stratification phenomenon that occurs when using a water bath for heating, and allowing the flowing water to have enough time to be heated by the heater 2, thereby improving the heat transfer efficiency.

[0033] Reference Figure 6: A first thermometer 14 and a second thermometer 15 are arranged in the first circulation chamber 12 from top to bottom along the vertical direction. The first thermometer 14 and the second thermometer 15 are both arranged on the inner ring wall of the separation ring 11. The first thermometer 14 and the second thermometer 15 are used to measure the temperature of the water flow in the first circulation chamber 12. The water temperature measured by the first thermometer 14 is the first temperature, and the water temperature measured by the second thermometer 15 is the second temperature. There is a temperature difference between the first temperature and the second temperature. A rated temperature difference threshold is preset for the temperature difference. When the temperature difference is less than the rated temperature difference threshold, the power of the circulation unit 4 is increased. When the temperature difference is greater than the rated temperature difference threshold, the power of the circulation unit 4 is reduced. The separation ring 11 is made of thermal insulation material.

[0034] The water flow entering the first circulation chamber 12 from the bottom of the first circulation chamber 12 flows from bottom to top in the vertical direction, and the water flow flowing in the first circulation chamber 12 will absorb heat from the heating kettle 3. In this way, as the water flow flows from bottom to top in the first circulation chamber 12, the temperature of the water flow in the first circulation chamber 12 gradually decreases. At this time, the higher the power of the circulation unit 4, the more water the circulation unit 4 injects into the first circulation chamber 12, and the faster the water flow rate in the first circulation chamber 12. There will not be a large difference in the temperature difference between the upper and lower layers of the water flow in the first circulation chamber 12. Considering the energy consumption problem, the power of the circulation unit 4 cannot be continuously increased, but a balance point needs to be found, that is, the temperature difference between the first temperature measured by the first thermometer 14 and the second temperature measured by the second thermometer 15 is within the rated temperature difference threshold, so that the temperature of the water flow in the first circulation chamber 12 in contact with the heating kettle 3 can be ensured to be within a constant temperature, and the water temperature at the lower part of the first circulation chamber 12 will not be higher, while the water temperature at the upper part of the first circulation chamber 12 will not be higher. The increase or decrease in the power of the circulation unit 4 mentioned above affects the amount of water injected into the first circulation chamber 12. When the power of the circulation unit 4 increases, the amount of water injected into the first circulation chamber 12 gradually increases, and the corresponding water flow rate in the first circulation chamber 12 increases; when the power of the circulation unit 4 decreases, the amount of water injected into the first circulation chamber 12 decreases, and the corresponding water flow rate in the first circulation chamber 12 decreases.

[0035] Reference Figure 1-Figure 10 : The water flow temperature in the first circulation chamber 12 is preset with a working water temperature threshold, the rated temperature difference threshold is less than the working water temperature threshold, the working water temperature threshold has a maximum water temperature and a minimum water temperature, the first temperature monitored by the first thermometer 14 is greater than the minimum water temperature, and the second temperature monitored by the second thermometer 15 is less than the maximum water temperature. When the temperature difference between the first temperature and the second temperature is within the rated temperature difference threshold, if the first temperature is less than the minimum water temperature, the power of the circulation unit 4 remains unchanged and the heater 2 increases the power. If the second temperature is greater than the maximum water temperature, the power of the circulation unit 4 remains unchanged and the heater 2 reduces the power.

[0036] The rated temperature difference threshold and the working water temperature threshold are both range values. The working water temperature threshold is set to make the preparation temperature meet the preparation requirements, while the rated temperature difference threshold is to improve the constant temperature stability of the water temperature under the premise of meeting the working water temperature threshold, thereby improving the quality of the prepared low-temperature refining agent. When preparing the low-temperature refining agent, according to the preparation requirements, the heating temperature usually needs to be in a constant temperature range. Here, the constant temperature range is called the working water temperature threshold. In the first circulation chamber 12, the first temperature value measured by the first thermometer 14 is the lowest, and the second temperature value measured by the second thermometer 15 is the highest. In this way, when judging whether the temperature during water bath heating exceeds or is lower than the working water temperature threshold, it can be confirmed by the first temperature and the second temperature. If the first temperature is less than the minimum water temperature, the power of the circulation unit 4 remains unchanged, the heater 2 increases the power, and the water temperature drawn into the first circulation chamber 12 by the circulation unit 4 increases. If the second temperature is greater than the maximum water temperature, the power of the circulation unit 4 remains unchanged, the heater 2 reduces the power, and the water temperature drawn into the first circulation chamber 12 by the circulation unit 4 decreases.

[0037] Reference Figure 3 and Figure 4 The circulation unit 4 includes a circulation pipe 41 which connects the bottom of the first circulation chamber 12 with the bottom of the second circulation chamber 13. A water pump 42 is arranged on the circulation pipe 41. The water pump 42 draws the water flow in the second circulation chamber 13 into the first circulation chamber 12 through the circulation pipe 41. An inlet is arranged at the connection between the circulation pipe 41 and the first circulation chamber 12. The inlet is a funnel-shaped structure, and a spoiler blade 43 is rotatably arranged in the inlet.

[0038] When the equipment is started, the water pump 42 continuously draws the water in the second circulation chamber 13 into the first circulation chamber 12 through the circulation pipe 41. Since the inlet is a funnel-shaped structure, the water flowing out of the circulation pipe 41 will slow down when passing through the inlet. At the same time, since the inlet is provided with a spoiler blade 43, the spoiler blade 43 is driven to rotate when the water flows through the spoiler blade 43, so that the water injected into the first circulation chamber 12 can evenly distribute the bottom of the heating kettle 3.

[0039] Reference Figure 3 , Figure 4 and Figure 7: A stirring unit 6 is arranged in the shell 1, and the stirring unit 6 includes a stirring shaft 61 which is rotatably arranged on the upper part of the shell 1 along the axis of the shell 1, and the stirring shaft 61 extends from the upper part of the heating kettle 3 to the heating kettle 3 along the axis of the shell 1, and a discharge port 31 is provided at the bottom of the heating kettle 3. The heating kettle 3 located in the shell 1 moves in the shell 1 along the vertical direction, and the moving path of the shell 1 includes a highest position and a lowest position. When the shell 1 is at the highest position, the bottom of the stirring shaft 61 extends to the discharge port 31 and blocks the discharge port 31, and a closed working chamber is formed in the heating kettle 3. When the shell 1 is at the lowest position, the bottom of the stirring shaft 61 slides out from the discharge port 31.

[0040] A first rotary driver 62 for driving the stirring shaft 61 to rotate is provided at the upper part of the stirring shaft 61. The first rotary driver 62 is preferably a servo motor. When the first rotary driver 62 is started, the first rotary driver 62 can drive the stirring shaft 61 to rotate. Stirring rods 63 are evenly provided on the side walls of the stirring shaft 61. After the stirring shaft 61 rotates, the stirring rods 63 are driven to rotate. Then, the heating kettle 3 is lifted and lowered in the vertical direction. The stirring shaft 61 does not move in the vertical direction. When the heating kettle 3 rises to the highest position, the lower part of the stirring shaft 61 extends into the discharge port 31 and the heating kettle 3 is lifted and lowered. The discharge port 31 on the heating kettle 3 is blocked. A switch valve is usually provided at the bottom of the conventional heating kettle 3. The switch valve is closed during stirring, but raw materials will accumulate on the upper part of the switch valve, and the stirring unit cannot stir the raw materials accumulated on the upper part of the switch valve. After the discharge port 31 of the heating kettle 3 is blocked by the stirring shaft 61, it is ensured that the stirring unit 6 can completely stir the raw materials in the heating kettle 3. After the stirring is completed, the heating kettle 3 is lowered, so that the stirring shaft 61 slides out of the heating kettle 3, so that the raw materials in the heating kettle 3 can be discharged from the bottom of the heating kettle 3 without taking out the heating kettle 3.

[0041] Reference Figure 6 : A plurality of stirring rods 63 are evenly arranged on the side wall of the stirring shaft 61 around the axis of the stirring shaft 61, and a sleeve 64 is sleeved on the stirring rod 63 along the extension direction of the stirring rod 63. The sleeve 64 is slidably matched with the stirring rod 63, and a first scraper 65 is fixedly arranged at one end of the sleeve 64 away from the stirring shaft 61.

[0042] When the stirring shaft 61 rotates, the stirring shaft 61 drives the stirring rod 63 to rotate, and the stirring rod 63 throws out the sleeve 64 through centrifugal force, so that the first scraper 65 arranged at the end of the sliding sleeve contacts the inner wall of the heating kettle 3, avoiding the situation that part of the raw material adheres to the inner wall of the heating kettle 3 and cannot be stirred by the stirring rod during the heating process.

[0043] Reference Figure 5: A sliding groove 66 is opened on the side wall of the stirring shaft 61 along the extension direction of the stirring shaft 61, and a second scraper 67 is slidably arranged in the sliding groove 66 along the extension direction of the sliding groove 66. When the heating kettle 3 is at the highest position, the bottom of the second scraper 67 contacts the bottom of the heating kettle 3. The second scraper 67 rotates under the drive of the stirring shaft 61 and forms a sweeping area. The sweeping area completely covers the bottom of the heating kettle 3. When the heating kettle 3 is at the lowest position, the bottom of the second scraper 67 is separated from the bottom of the heating kettle 3.

[0044] Due to the gravity of the second scraper 67, the second scraper 67 is always in contact with the bottom of the heating kettle 3 when the stirring shaft 61 rotates. When the heating kettle 3 is at the highest position, the second scraper 67 can scrape and stir the raw materials at the bottom of the heating kettle 3 to avoid the bottom being hardened due to heating.

[0045] Reference Figure 7 and Fig.10 A lifting unit 32 for driving the heating kettle 3 to move in a vertical direction is arranged at the upper part of the heating kettle 3. The lifting unit 32 includes an extension ring 325 fixedly sleeved on the outer periphery of the heating kettle 3. A fixing frame 323 is arranged at the lower part of the extension ring 325. The fixing frame 323 is fixedly arranged on the inner wall of the shell 1. A threaded rod 322 is arranged on the extension ring 325 in a vertical direction. The threaded rod 322 is threadedly matched with the extension ring 325. Two ends of the threaded rod 322 are respectively rotatably matched with the fixing frame 323 and the shell 1. A guide rod 324 is arranged on one side of the threaded rod 322 parallel to the extension direction of the threaded rod 322. Two ends of the guide rod 324 are respectively fixedly connected with the fixing frame 323 and the upper part of the shell 1. A second rotation driver 321 for driving the threaded rod 322 to rotate is arranged at the upper end of the threaded rod 322.

[0046] The second rotary driver 321 is preferably a servo motor. When the second rotary driver 321 is started, the threaded rod 322 starts to rotate. The guide rod 324 is used to limit the rotation of the extension ring 325. In this way, after the threaded rod 322 rotates, the extension ring 325 can drive the heating kettle 3 to move in the vertical direction.

[0047] Reference Figure 1-Figure 10 The present invention also relates to a constant temperature treatment process for dyeing and finishing auxiliaries, which uses a constant temperature treatment device for dyeing and finishing auxiliaries, and the specific preparation steps are as follows: S1. Add deionized water and isohexylene glycol into a stirring tank and stir to mix evenly; S2. Then, continue stirring and add isomeric tridecanol polyoxyethylene ether, fatty acid methyl ester ethoxylate, ABS and penetrant JFC in sequence. After the addition is completed, continue stirring for 5-20 minutes to complete the preparation.

[0048] Reference Figure 1-Figure 10The specific formula ratio of dyeing and finishing auxiliaries is as follows: the ratio of fatty acid methyl ester ethoxylate is 20%-25%, the ratio of isomeric tridecyl alcohol polyoxyethylene ether is 5%-10%, the ratio of ABS is 1%-5%, the ratio of penetrant JFC is 5%-15%, the ratio of isohexanediol is 5%-10%, and the ratio of deionized water is 50%-60%.

[0049] Working principle: Before preparation, various preparation raw materials need to be put into the heating kettle 3 in sequence. A stirring unit 6 is provided in the heating kettle 3. When the raw materials are put into the heating kettle 3 in sequence, the stirring unit 6 in the heating kettle 3 starts to stir and mix the raw materials in the heating kettle 3. At the same time, the heater 2 provided on the outer shell 1 is started, and the heater 2 transfers heat to the second circulation chamber 13 through the outer shell 1, so that the clean water in the second circulation chamber 13 can be heated. While the stirring unit 6 is stirring the raw materials in the heating kettle 3, the circulation unit 4 is also started synchronously. The circulation unit 4 draws the water flow in the second circulation chamber 13 into the first circulation chamber 12, and the circulation unit 4 injects the water flow into the first circulation chamber 12 from the bottom of the first circulation chamber 12. In this way, the water in the first circulation chamber 12 directly in contact with the heating kettle 3 flows from bottom to top in a vertical direction, avoiding the occurrence of water temperature stratification around the heating kettle 3. This is because after the circulation unit 4 injects the heated water into the first circulation chamber 12, the water in the upper layer of the first circulation chamber 12 passes over the upper part of the separation ring 11 and enters the second circulation chamber 13. It is worth noting that the volume of the first circulation chamber 12 is smaller than that of the second circulation chamber 13, and both the first circulation chamber 12 and the second circulation chamber 13 are annular structures, so the ring diameter of the first circulation chamber 12 is smaller than the ring diameter of the second circulation chamber 13. When the circulation unit 4 is started, the amount of water drawn from the second circulation chamber 13 by the circulation unit 4 is equal to the amount of water injected into the first circulation chamber 12, so that the water flow rate in the first circulation chamber 12 is greater than the water flow rate in the second circulation chamber 13. The faster the water flow rate in the first circulation chamber 12, the less likely the water in the first circulation chamber 12 will be stratified by water temperature, and the slower the water flow in the second circulation chamber 13, the water flow in the second circulation chamber 13 can be heated by the heater 2 for a longer time, ensuring the heating effect of the heater 2, thus avoiding the water temperature stratification phenomenon that occurs when using a water bath for heating, and allowing the flowing water to have enough time to be heated by the heater 2, thereby improving the heat transfer efficiency.

[0050] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the protection scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
