Description

[0001] This application is a divisional application based on the parent application with application number 202310725370.0, application date June 19, 2023, entitled "A dye liquor preparation device and cleaning method with self-cleaning function". Technical Field

[0002] This invention relates to the field of cleaning dye liquor preparation apparatus, and more specifically, to a dye liquor preparation apparatus with self-cleaning function. Background Technology

[0003] In the textile printing and dyeing industry, before printing and dyeing, primary dyes, water, and auxiliaries need to be mixed and stirred in a dye liquor preparation device to obtain the dye. This process requires a specific temperature environment. Therefore, to heat the mixed liquid, one method is to install a coil in the dye liquor preparation device, using the coil to conduct heat and heat the mixed liquid. Because the dye is stirred in the dye liquor preparation device, some dye liquor remains on the tube wall after being discharged. This residual dye liquor causes a change in the actual ratio of primary dyes entering the device during the next dye liquor preparation, resulting in an inability to obtain the desired color and a significant color difference between the produced dye and the desired dye. Furthermore, because the coil is fixed at the bottom of the dye liquor preparation device, and the device has a certain height, it is difficult to clean. Existing manual cleaning methods are inefficient and difficult to clean thoroughly, especially the outer surface of the coil. Summary of the Invention

[0014] Figure 1 This is a schematic diagram of the structure of an embodiment of the present invention; Figure 2 This is a top view of the coil in an embodiment of the present invention; Figure 3 This is a flowchart of a method according to an embodiment of the present invention.

[0015] The diagram consists of: cylinder 1, coil 2, partition 3, upper cavity 4, lower cavity 5, air source 6, air pump 7, first air outlet 8, second air outlet 9, water source 10, and water pump 11. Detailed Implementation

[0016] The technical solution of the present invention will now be described in detail with reference to the accompanying drawings.

[0017] like Figure 1 and Figure 2 As shown in the figure, an embodiment of the present invention provides a dye liquor preparation device with self-cleaning function, comprising a cylinder 1, a coil 2, and a cleaning component. The coil 2 is fixedly connected to the lower part of the cylinder 1, and the bottom of the cylinder 1 is provided with a drain port. The wall of the cylinder 1 includes an outer wall and an inner wall, forming a cavity between the outer wall and the inner wall. A partition 3 is provided in the cavity, dividing the cavity into an upper cavity 4 and a lower cavity 5. The upper cavity 4 is provided with a water outlet, and the inner wall of the lower cavity 5 is provided with an air outlet. The cleaning component is connected to the upper cavity and the lower cavity respectively.

[0018] The dye liquor preparation apparatus of the above embodiment utilizes its own structure to clean the dye liquor preparation apparatus, especially the coils within it. After the dye liquor is prepared and transported to the dyeing vat, the apparatus automatically cleans the residual dye liquor on the inner wall of the apparatus and the outer wall of the coils. The waste liquid from cleaning is discharged from the drain port. A cavity is formed between the outer and inner walls of the cylinder 1, and this cavity is divided into an upper cavity 4 and a lower cavity 5. The cleaning component is connected to the upper cavity 4 for introducing water. The cleaning component is connected to the lower cavity 5 for introducing gas. During operation, water is first introduced, flowing out from the outlet of the upper cavity 4 to rinse the inner wall of the cylinder 1. Then, gas is introduced, flowing out from the outlet of the lower cavity 5 to rinse the coils. Part of the gas directly impacts the outer wall of the coil, causing residual dye solution to detach from the outer wall and fall into the water; another part of the gas impacts the water accumulated at the bottom of cylinder 1, using the water to flush the outer wall of the coil, causing residual dye solution on the outer wall of the coil to fall into the water. In this way, after the dye solution is prepared and transported to the dyeing vat, the cleaning component is activated to achieve the self-cleaning function of the inner wall of cylinder 1 and the coil 2 located in cylinder 1.

[0019] Preferably, the cleaning assembly includes an air source 6 and an air pump 7. An air inlet is located on the outer wall of the lower cavity 5, and the air inlet and the air outlet of the air source 6 are connected via an air pipe. The air pump 7 is connected to the air pipe. Gas is introduced into the lower cavity 5 by using the air source 6 and the air pump 7. During operation, the air source 6 and the air pump 7 are turned on, and the amount of gas entering the lower cavity 5 is adjusted by the air pump 7. The gas is discharged from the air outlet of the lower cavity 5 and enters the cylinder 1.

[0020] Preferably, the air outlet includes a first air outlet 8, which is located on the lower part of the inner wall of the lower cavity 5, opposite to the coil 2. In this way, the gas discharged from the first air outlet 8 rushes towards the coil 2, which can wash away some of the residual dye liquid on the surface of the coil 2.

[0021] Preferably, the air outlet further includes a second air outlet 9, which is located on the upper part of the inner wall of the lower cavity 5 and above the liquid surface inside the cylinder 1. The second air outlet 9 is equipped with a nozzle. When water flows down from the upper part of the inner wall of the cylinder 1, the airflow from the nozzle impacts the water flowing to the second air outlet 9, causing the water to change its flow direction under the influence of the airflow and flow towards other parts of the inner wall, impacting those parts and cleaning away residual dye. Thus, in the cylinder 1, the inner wall above the liquid surface is impacted by both the water flowing from the outlet of the upper cavity 4 and the water flow from the nozzle, achieving cleaning of the inner wall of the cylinder 1.

[0022] Preferably, the cleaning assembly further includes a water source 10 and a water pump 11. The outer wall of the upper cavity 4 is provided with a water inlet. The water inlet and the water outlet of the water source 10 are connected by a water pipe, and the water pump 11 is connected to the water pipe.

[0023] Water is introduced into the upper cavity 4 by setting up a water source 10 and a water pump 11. During operation, the water source 10 and the water pump 11 are turned on, and the water flow into the upper cavity 4 is regulated by the water pump 11. The water is discharged from the outlet of the upper cavity 4 and flows downward along the inner wall of the cylinder 1. During the flow, the water flow washes away the residual dye liquid adhering to the inner wall of the cylinder 1.

[0024] Preferably, the upper part of the inner wall of the upper cavity 4 bends away from the inner cavity of the cylinder 1, and the top of the inner wall of the upper cavity 4 is lower than the top of the outer wall of the upper cavity 4; an outlet of the upper cavity 4 is formed above the top of the inner wall of the upper cavity 4. The bending of the upper part of the inner wall of the upper cavity 4 away from the inner cavity of the cylinder 1 allows the water flowing from the outlet to flow along the inner wall of the cylinder 1. The bending of the upper part of the inner wall of the upper cavity 4 guides the water flow out of the outlet. If the water flow cannot flow along the inner wall of the cylinder 1, the water pump 11 is adjusted to reduce the water flow rate, so that the water flow flows along the inner wall of the cylinder 1. The outlet is arranged circumferentially in a ring shape. This allows the water flow to reach the entire inner wall of the cylinder 1.

[0025] Preferably, the height of the upper cavity 4 is one-quarter to one-sixth of the height of the cylinder 1. Water is introduced into the upper cavity 4. Choosing an appropriate height for the upper cavity 4 provides a suitable position for the second air outlet 9 in the lower cavity 5.

[0026] Preferably, the second air outlets 9 are arranged in rows, and within each row of second air outlets 9, the arrangement is asymmetrical with the axis of the cylinder 1 as the line of symmetry. Each second air outlet 9 corresponds to a nozzle. Because the nozzles are asymmetrically arranged along the center point on the same horizontal plane, the water jets from the nozzles flow towards the inner wall of the cylinder 1, rather than the second air outlets 9, thus achieving the function of rinsing the inner wall of the cylinder 1. Since the flow rate of water flowing down from above the second air outlets 9 is uneven when it reaches the second air outlets 9, the water jets from the nozzles are also different, flowing towards different positions on the inner wall of the cylinder 1. In addition, adjusting the gas flow rate in the nozzles can also achieve the same effect of flowing towards different positions on the inner wall of the cylinder 1, thereby rinsing different positions on the inner wall of the cylinder 1. The second air outlets 9 are arranged in rows. Multiple rows of second air outlets 9 are arranged, and each second air outlet 9 is equipped with a nozzle, which can rinse different positions on the inner wall of the cylinder 1.

[0027] like Figure 3 As shown, this embodiment also provides a cleaning method for a dye preparation apparatus, including: Step 10: Turn off the air pump 7 and turn on the water pump 11 to introduce water from the water source 10 into the upper cavity 4. The water flows out from the outlet of the upper cavity 4 and flows downward along the inner wall of the cylinder 1.

[0028] Step 20: When the water level in the cylinder 1 submerges part of the coil 2, turn off the water pump 11 and turn on the air pump 7 to flush the coil 2 using the first air outlet 8; then open the drain outlet to discharge the liquid.

[0029] Step 30: Close the drain port, turn on the water pump 11 and the air pump 7 to introduce water from the water source 10 into the upper cavity 4. The water flows out from the outlet of the upper cavity 4 and flows down along the inner wall of the cylinder 1. When the water level in the cylinder 1 reaches the middle of the cylinder 1, turn off the water pump 11 and use the first air outlet 8 and the second air outlet 9 to rinse the cylinder 1 and the coil 2. Then open the drain port to discharge the liquid.

[0030] In the above method, firstly, the inner wall of the cylinder 1 is preliminarily cleaned. In step 10, water flows out from the outlet of the upper cavity 4 and flows downward along the inner wall of the cylinder 1. During the downward flow of water, the inner wall of the cylinder 1 is rinsed. The flowing water is collected at the bottom of the cylinder 1.

[0031] Then, the coil 2 is cleaned. In step 20, when the water level in the cylinder 1 partially submerges the coil 2, the water pump 11 is turned off and the air pump 7 is turned on to flush the coil 2 using the first air outlet 8; then the drain outlet is opened to discharge the liquid. The water level in the cylinder 1 partially submerges the coil 2. In this way, part of the gas discharged from the first air outlet 8 directly impacts the outer wall of the coil 2, causing some of the residual dye liquid to detach from the outer wall of the coil 2 and fall into the water; the other part of the gas impacts the water accumulated at the bottom of the cylinder 1, using the water to flush the outer wall of the coil 2, causing some of the residual dye liquid on the outer wall of the coil to fall into the water. In this way, in step 20, the outer wall of the coil 2 can be cleaned by simultaneously flushing it with airflow and waterflow. If only airflow is used for flushing, the airflow will be difficult to reach the inner wall of the coil 2. If only waterflow is used for flushing, the impact force of the waterflow is not as strong as the direct flushing with airflow. Preferably, the step of rinsing the coil 2 using the first air outlet 8 includes: using a portion of the gas blown out of the first air outlet 8 to agitate the liquid flow, thereby rinsing away residual dye on the surface of the coil 2; and using another portion of the gas blown out of the first air outlet 8 to blow onto the surface of the coil 2, thereby rinsing away residual dye on the surface of the coil 2. In this way, the entire outer surface of the coil 2 is impacted by water flow while the surface of the coil 2 is directly impacted by airflow. Both act simultaneously on the coil 2, interacting to achieve cleaning. Since the waste liquid contains the most dye during the first cleaning, the drain outlet is opened to discharge the waste liquid.

[0032] Finally, the entire inner wall of cylinder 1 is cleaned again. In step 30, the drain port is closed, and the water pump 11 and air pump 7 are turned on to introduce water from water source 10 into the upper cavity 4. The water flows out from the outlet of the upper cavity 4 and flows downward along the inner wall of cylinder 1. The inner wall of cylinder 1 is rinsed again. When the water flows to the second air outlet 9, the water is sprayed onto the inner wall of cylinder 1 through the nozzle, realizing another method of rinsing the inner wall of cylinder 1.

[0033] When the water level in cylinder 1 reaches the middle of cylinder 1, which is above the second air outlet 9, the water pump 11 is turned off, and cylinder 1 and coil 2 are flushed using the first air outlet 8 and the second air outlet 9. Gas discharged from the first air outlet 8 agitates the water flow at the bottom of cylinder 1. Gas discharged from the second air outlet 9 agitates the water flow in the middle of cylinder 1. In this way, the water is blown by gas at both the top and bottom, achieving flow. During the flow, the inner wall of cylinder 1 and the coil are flushed again. After flushing is complete, the drain port is opened to discharge the liquid.

[0034] In the above scheme, after step 20 is completed, the process can return to step 10 and repeat steps 10 and 20 once. This ensures that most of the residual dye is rinsed into the water stream. Then, step 30 is performed.
