Description
Technical Field
[0001] This application relates to the field of dyeing equipment technology, and in particular to a dyeing liquor tank for a high-temperature and high-pressure dyeing machine. Background Technology
[0002] In recent years, with the continuous progress in the industrial manufacturing sector and the increasing demand for energy management, the research and development of various high-efficiency equipment has become one of the core tasks of technological development. Among them, high-temperature and high-pressure dyeing machines play a vital role in the textile industry, which can significantly improve the color uniformity and color fixation efficiency of textiles.
[0003] With the acceleration of industrialization, competition in the textile industry is becoming increasingly fierce. High-temperature and high-pressure dyeing machines not only need to meet dyeing requirements in terms of performance, but also need to meet increasingly stringent environmental standards in order to adapt to the requirements of sustainable development.
[0004] Traditional high-temperature and high-pressure dyeing machines generate a large amount of waste hot water during operation. This waste hot water usually contains high-temperature energy, and direct discharge would result in energy waste. Utility Model Content
[0005] In order to reduce the energy loss caused by the direct discharge of a large amount of waste hot water generated during the dyeing process and improve the utilization rate of heat energy, this application provides a dye liquor tank for a high-temperature and high-pressure dyeing machine.
[0006] This application provides a dye liquor tank for a high-temperature and high-pressure dyeing machine, which adopts the following technical solution: it includes a dye liquor tank body for connecting to the dyeing machine, and also includes a waste heat utilization structure embedded in the tank wall of the dye liquor tank body. One end of the waste heat utilization structure is connected to the waste discharge pipe of the dyeing machine, and the other end of the waste heat utilization structure is connected to a discharge pipe, which is exposed outside the dye liquor tank body.
[0007] By adopting the above technical solution, the waste hot water generated during the dyeing process enters the waste heat utilization structure through the waste discharge pipe. The waste heat utilization structure transfers the heat in the waste hot water to the dye liquor in the dye liquor tank, reducing the energy loss caused by the direct discharge of a large amount of waste hot water generated during the dyeing process and improving the utilization rate of heat energy.
[0008] Preferably, a heating chamber is provided on the wall of the dyeing tank body, and the heating chamber is evenly distributed along the circumference of the dyeing tank body on the tank wall. The waste heat utilization structure includes a waste heat recovery pipe, which is embedded in the heating chamber. Waste hot water discharged from the dyeing machine flows through the waste heat recovery pipe. One end of the waste heat recovery pipe is connected to the waste discharge pipe of the dyeing machine, and the other end of the waste heat recovery pipe is connected to the discharge pipe.
[0009] By adopting the above technical solution, the heating chamber collects heat from the waste hot water, reducing the probability of heat loss. The heat collected by the heating chamber preheats the dye liquor in the dye bath tank. Preheating can reduce the temperature fluctuation of the dye liquor in the dye bath tank after it enters the dyeing machine, ensuring that the dye liquor can penetrate into the fabric evenly and quickly when it reaches the working temperature, thereby improving the dyeing effect and product quality.
[0010] Preferably, the waste heat recovery pipe is non-linear and is evenly distributed in the heating chamber along the circumference of the dye bath body.
[0011] By adopting the above technical solution, the non-linear waste heat recovery pipe is evenly distributed circumferentially in the heating chamber, which increases the contact area between the waste heat recovery pipe and the gas in the heating chamber, and can transfer more heat to the heating chamber, and then to the dye liquor in the dye liquor tank body.
[0012] Preferably, there are two heating chambers, namely a first heating chamber and a second heating chamber, which are arranged in a ring. The first heating chamber is located on the side of the dye bath body near the inner wall of the dye bath body. The waste heat recovery pipe is disposed in the first heating chamber. A plurality of heating pipes are also disposed in the wall of the dye bath body. The plurality of heating pipes are disposed at equal angles along the circumference of the dye bath body in the second heating chamber.
[0013] By adopting the above technical solution, when the heat collected in the waste hot water is insufficient to raise the dye liquor in the dye bath to the preheating temperature, the heating tube in the second heating chamber plays an auxiliary preheating role; when the heat in the waste hot water is sufficient to raise the dye liquor to the preheating temperature, the heating tube does not work, thus reducing energy consumption.
[0014] Preferably, a temperature sensor is provided on the body of the dye bath tank. The temperature sensor is used to monitor the temperature inside the body of the dye bath tank in real time. The detection end of the temperature sensor is embedded in the body of the dye bath tank, and the reading end of the temperature sensor is exposed outside the body of the dye bath tank.
[0015] By adopting the above technical solution, the temperature sensor monitors the temperature of the dye solution in the dye bath tank in real time. When the temperature of the dye solution in the dye bath tank is lower than the preheating temperature of the dye solution, the heating tube is controlled to provide auxiliary heating to the dye solution. When the temperature of the dye solution in the dye bath tank reaches the preheating temperature of the dye solution, the heating tube is controlled to stop working.
[0016] Preferably, the dye bath tank body is provided with an observation window, which penetrates the tank wall radially along the dye bath tank body and extends along the axial direction of the dye bath tank body. The dye bath tank body is provided with a transparent plate for sealing the observation window, and a scale is engraved on the transparent plate along the axial direction of the dye bath tank body.
[0017] By adopting the above technical solution, the transparent plate allows operators to easily observe the state of the dye solution inside the dye bath tank. When the level of the dye solution inside the dye bath tank is low, the dye solution can be replenished in a timely manner.
[0018] Preferably, the dyeing tank body is provided with a stirring structure, the stirring structure including a stirring motor and a stirring paddle, the stirring motor is disposed on the top of the dyeing tank body, the stirring paddle is disposed inside the dyeing tank body, and one end of the stirring paddle is used to be coaxially connected to the output shaft of the stirring motor.
[0019] By adopting the above technical solution, the stirring structure stirs the dye liquid in the dye bath tank evenly, which not only makes the dye liquid have a certain fluidity, but also makes the dye liquid and the inner wall of the dye bath tank body fully contact each other, so as to maximize the heat provided by the heating chamber and distribute the heat evenly in the dye liquid.
[0020] Preferably, the stirring paddle is positioned and reciprocated within the dyeing tank body along the axial direction of the dyeing tank body.
[0021] By adopting the above technical solution, the stirring paddle slides back and forth along the axial direction of the dye bath tank body, making the stirring paddle responsive and allowing for real-time height adjustment according to the height of the dye bath liquid level inside the dye bath tank body.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. Wastewater generated during the dyeing process enters the waste heat utilization structure through the waste discharge pipe. The waste heat utilization structure transfers the heat in the wastewater to the dye liquor in the dye liquor tank, reducing the energy loss caused by the direct discharge of a large amount of wastewater generated during the dyeing process and improving the utilization rate of heat energy.
[0024] 2. The heating chamber collects heat from the waste hot water, reducing the probability of heat loss. The heat collected in the heating chamber preheats the dye liquor in the dye bath tank. Preheating can reduce the temperature fluctuation of the dye liquor in the dye bath tank after it enters the dyeing machine, ensuring that the dye liquor can penetrate into the fabric evenly and quickly when it reaches the working temperature, thereby improving the dyeing effect and product quality.

Detailed Implementation
[0030] The present application will be further described in detail below with reference to the accompanying drawings.
[0031] This application discloses a dye liquor tank for a high-temperature and high-pressure dyeing machine, which reduces energy loss caused by the direct discharge of a large amount of waste hot water generated during the dyeing process and improves the utilization rate of heat energy.
[0032] refer to Figure 1 , Figure 2 and Figure 3 A dye liquor tank for a high-temperature, high-pressure dyeing machine includes a tank body 110 and a waste heat utilization structure. The tank body 110 has two heating chambers on its wall: a first heating chamber 121 and a second heating chamber 122. The first heating chamber 121 and the second heating chamber 122 are arranged concentrically, with the first heating chamber 121 located on the inner side and the second heating chamber 122 on the outer side. The waste heat utilization structure includes a waste heat recovery pipe 120 through which waste hot water discharged from the dyeing machine flows. The waste heat recovery pipe 120 is non-linear and is evenly distributed circumferentially within the first heating chamber 121 along the dye liquor tank body 110. The waste heat recovery pipe 120 can be a serpentine waste heat recovery pipe made of stainless steel. In other embodiments, the waste heat recovery pipe 120 has a spiral design to increase the flow length of the waste hot water within it, ensuring a more uniform heat distribution throughout the dye liquor tank body 110 and thus improving heat transfer efficiency.
[0033] Specifically, one end of the waste heat recovery pipe 120 is connected to a discharge pipe 123, and the other end is connected to a water inlet pipe 124. The end of the water inlet pipe 124 away from the waste heat recovery pipe 120 is used to connect to the waste discharge pipe of the dyeing machine. Both the water inlet pipe 124 and the discharge pipe 123 are exposed outside the dye liquor tank body 110. The waste hot water generated during the dyeing process flows through the waste discharge pipe on the dyeing machine and into the waste heat recovery pipe 120 via the water inlet pipe 124. The waste heat recovery pipe 120 transfers the heat in the waste hot water to the first heating chamber 121. The first heating chamber 121 collects the heat in the waste hot water, reducing the probability of heat loss, and then transfers it to the dye liquor in the dye liquor tank body 110 for preheating. Preheating can reduce the temperature fluctuation of the dye liquor in the dye liquor tank body 110 after it enters the dyeing machine, ensuring that the dye liquor can penetrate into the fabric evenly and quickly when it reaches the working temperature, thereby improving the dyeing effect and product quality. Moreover, it reduces the energy loss caused by the direct discharge of a large amount of waste hot water generated during the dyeing process and improves the utilization rate of heat energy.
[0034] In addition, refer to Figure 1 and Figure 4 The dye bath tank body 110 is also equipped with multiple heating tubes 125 inside the tank wall. The multiple heating tubes 125 are arranged at equal angles along the circumference of the dye bath tank body 110 in the second heating chamber 122. A temperature sensor 126 is installed on the dye bath tank body 110. The temperature sensor 126 is used to monitor the temperature inside the dye bath tank body 110 in real time. The detection end of the temperature sensor 126 is embedded in the dye bath tank body 110, and the reading end of the temperature sensor 126 is exposed outside the dye bath tank body 110. The temperature sensor 126 can accurately monitor temperature changes inside the dye bath tank body 110, and it is also convenient for operators to read the temperature information inside the dye bath tank body 110 from the outside of the dye bath tank body 110.
[0035] Temperature sensor 126 monitors the temperature of the dye liquor in the dye bath tank 110 in real time. When the temperature of the dye liquor in the dye bath tank 110 is lower than the preheating temperature of the dye liquor, it indicates that the heat collected in the waste hot water is insufficient to allow the dye liquor in the dye bath tank 110 to reach the preheating temperature. The heating tube 125 is then controlled to provide auxiliary heating to the dye liquor. When the temperature of the dye liquor in the dye bath tank 110 reaches the preheating temperature of the dye liquor, the heating tube 125 is controlled to stop working, thus reducing energy consumption.
[0036] Further, refer to Figure 1An observation window 111 is provided on the body 110 of the dyeing solution tank. The observation window 111 penetrates the tank wall of the body 110 radially. The length direction of the observation window 111 is opened along the axial direction of the body 110 of the dyeing solution tank. A transparent plate 112 is provided on the body 110 of the dyeing solution tank for sealing the observation window 111. The transparent plate 112 can be a high-transmittance glass plate or a transparent plastic plate to facilitate the operator to observe the state of the dye solution in the tank. A scale 113 is engraved on the transparent plate 112 along the axial direction of the body 110 of the dyeing solution tank, so that the operator can monitor the horizontal position of the dye solution at any time and replenish the dye solution in a timely manner.
[0037] In addition, refer to Figure 1 and Figure 2 The dye bath tank body 110 is connected to two feeding pipes 114, which are used to replenish water and dye respectively. A sealing cap 115 is fitted on the feeding pipe 114, and the sealing cap 115 is threaded to the outer wall of the feeding pipe 114. The dye bath tank body 110 is provided with a stirring structure 130, which includes a stirring motor 131 and a stirring paddle 132. The stirring motor 131 is located at the top of the dye bath tank body 110, and the stirring paddle 132 is located inside the dye bath tank body 110. The stirring paddle 132 is positioned and reciprocates within the dye bath tank body 110 along the axial direction of the dye bath tank body 110.
[0038] Specifically, a transmission gear 133 is coaxially connected to the output shaft of the stirring motor 131. The transmission gear 133 is embedded in the top wall of the dye bath body 110. A meshing gear 134 is also embedded in the top wall of the dye bath body 110. The meshing gear 134 and the transmission gear 133 are meshed together. A drive cylinder 135 is also provided on the top of the dye bath body 110. The bottom of the drive cylinder 135 is coaxially connected to the transmission gear 133. The piston rod of the drive cylinder 135 passes through the dye bath body 110. The top wall of the stirring structure 130 is coaxially connected to the stirring paddle 132. The stirring structure 130 stirs the dye liquid in the dye liquid tank body 110 evenly, which not only makes the dye liquid have a certain fluidity, but also makes the dye liquid and the inner wall of the dye liquid tank body 110 fully contact each other, so as to maximize the heat provided by the heating chamber and distribute the heat evenly in the dye liquid. The stirring paddle 132 slides back and forth along the axis of the dye liquid tank body 110, which makes the stirring paddle 132 have follow-up properties and can adjust the height in real time according to the height of the dye liquid in the dye liquid tank body 110.
[0039] The implementation principle of the dye liquor tank of a high-temperature and high-pressure dyeing machine according to an embodiment of this application is as follows: the waste hot water generated during the dyeing process flows through the waste discharge pipe on the dyeing machine and into the waste heat recovery pipe 120 via the water inlet pipe 124. The waste hot water exchanges heat with the dye liquor inside the dye liquor tank body 110 through the waste heat recovery pipe 120, directly increasing the initial temperature of the dye liquor. At the same time, under the non-linear design, the waste heat recovery pipe 120 can ensure a longer water flow path, increasing the heat exchange area and thus improving the heat transfer efficiency. Preheating can reduce the temperature fluctuation of the dye liquor in the dye liquor tank body 110 after entering the dyeing machine during the dyeing process, ensuring that the dye liquor can penetrate into the fabric evenly and quickly when it reaches the working temperature, thereby improving the dyeing effect and product quality. Moreover, it reduces the energy loss caused by the direct discharge of a large amount of waste hot water generated during the dyeing process and improves the utilization rate of heat energy.

Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
