Description

Technical Field

[0001] The present invention relates to the field of dye liquor preparation device cleaning, and in particular to a dye liquor preparation device with self-cleaning function and a cleaning method. Background Art

[0002] In the field of textile printing and dyeing, before dyeing, primary dyes, water, and auxiliaries are mixed and stirred in a dye liquor preparation device to produce the dye. This process requires a certain temperature environment. Therefore, to heat the mixed liquid, one method is to install a coil in the dye liquor preparation device to achieve heat conduction through the coil, thereby heating the mixed liquid. Since the dye is stirred in the dye liquor preparation device, some dye liquor will still adhere to the tube wall after exiting the dye liquor preparation device. This residual dye liquor will cause the actual ratio of the primary dyes entering the device to change during the next dye liquor preparation, making it impossible to obtain the desired color dye, resulting in a large color difference between the produced dye and the desired dye. Because the coil is fixed at the bottom of the dye liquor preparation device and the dye liquor preparation device is at a certain height, it is difficult to clean. Existing manual cleaning methods are not only inefficient, but also difficult to clean, especially the outer surface of the coil. Summary of the Invention

[0023] Figure 3 It is a flow chart of a method according to an embodiment of the present invention.

[0024] The figure consists of: a cylinder 1, a coil 2, a partition 3, an upper cavity 4, a lower cavity 5, an air source 6, an air pump 7, a first air outlet 8, a second air outlet 9, a water source 10, and a water pump 11. DETAILED DESCRIPTION

[0025] The technical solution of the present invention is described in detail below with reference to the accompanying drawings.

[0026] like Figure 1 and Figure 2 As shown, a dye liquor preparation device with self-cleaning function according to an embodiment of the present invention includes a cylinder 1, a coil 2 and a cleaning assembly, wherein the coil 2 is fixedly connected to the lower part of the cylinder 1, and a drain port is provided at the bottom of the cylinder 1; the wall surface of the cylinder 1 includes an outer wall and an inner wall, a cavity is formed between the outer wall and the inner wall, a partition 3 is provided in the cavity, and the partition divides 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 assembly is communicated with the upper cavity and the lower cavity respectively.

[0027] The dye liquor preparation device of the above embodiment utilizes its own structure to clean the dye liquor preparation device, particularly the coils therein. After the dye liquor preparation device completes dye liquor preparation and transports it to the dye vat, the dye liquor remaining on the inner wall of the dye liquor preparation device and on the outer wall of the coils is automatically cleaned, and the resulting waste liquid is discharged from the drain port. A cavity is formed between the outer wall and the inner wall of the barrel 1, which is divided into an upper cavity 4 and a lower cavity 5. A cleaning assembly is connected to the upper cavity 4 for admitting water. The cleaning assembly is connected to the lower cavity 5 for admitting gas. During operation, water is first introduced, flowing out of the water outlet of the upper cavity 4 to rinse the inner wall of the barrel 1, and then gas is introduced, flowing out of the gas outlet of the lower cavity 5 to rinse the coils. A portion of the gas directly impacts the outer wall of the coil, causing any remaining dye to escape and fall into the water. Another portion 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, causing any remaining dye to fall into the water. In this way, after a single dye is prepared and delivered to the dye vat, the cleaning component is activated, achieving a self-cleaning function for the inner wall of the cylinder 1 and the coil 2 located therein.

[0028] Preferably, the cleaning assembly includes an air source 6 and an air pump 7. An air inlet is provided on the outer wall of the lower cavity 5. The air inlet and the air outlet of the air source 6 are connected via an air pipe, and the air pump 7 is connected to the air pipe. By providing the air source 6 and the air pump 7, gas is introduced into the lower cavity 5. 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 cylindrical body 1.

[0029] Preferably, the gas outlet includes a first gas outlet 8, which is located at 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 gas outlet 8 rushes towards the coil 2 and can flush away some residual dye on the surface of the coil 2.

[0030] Preferably, the air outlet further comprises a second air outlet 9, which is located at the upper portion of the inner wall of the lower cavity 5 and above the liquid level in the cylinder 1, and a nozzle is provided on the second air outlet 9. When water flows down from the upper portion of the inner wall of the cylinder 1, the airflow ejected from the nozzle impacts the water flowing to the second air outlet 9, so that the water, driven by the airflow, changes its flow direction and flows to other parts of the inner wall, impacting other parts of the inner wall and cleaning the residual dye solution on the inner wall. In this way, in the cylinder 1, the inner wall located above the liquid level is impacted by the water flowing out of the water outlet of the upper cavity 4 on the one hand, and by the water flow ejected from the nozzle on the other hand, thereby cleaning the inner wall of the cylinder 1.

[0031] Preferably, the cleaning assembly further comprises a water source 10 and a water pump 11. A water inlet is provided on the outer wall of the upper cavity 4, the water inlet being connected to the water outlet of the water source 10 via a water pipe, and the water pump 11 being connected to the water pipe. By providing the water source 10 and the water pump 11, water is introduced into the upper cavity 4. During operation, the water source 10 and the water pump 11 are turned on, and the amount of water entering the upper cavity 4 is regulated by the water pump 11. Water is discharged from the water outlet of the upper cavity 4 and flows downward along the inner wall of the cylinder 1. During the flow, the water flushes the inner wall of the cylinder 1, washing away any residual dye adhering to the inner wall of the cylinder 1.

[0032] Preferably, the upper portion of the inner wall of the upper cavity 4 is bent 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; the water outlet of the upper cavity 4 is formed above the top of the inner wall of the upper cavity 4. The upper portion of the inner wall of the upper cavity 4 is bent away from the inner cavity of the cylinder 1, so that the water flowing out of the water outlet flows along the inner wall of the cylinder 1. The upper portion of the inner wall of the upper cavity 4 is bent to guide the water flowing out of the water outlet. If the water flow cannot flow along the inner wall of the cylinder 1, then the water pump 11 is adjusted to reduce the water flow so that the water flow flows along the inner wall of the cylinder 1. The water outlet is arranged circumferentially in a ring shape. This allows the water flow to flow to the entire inner wall of the cylinder 1.

[0033] Preferably, the height of the upper cavity 4 is one-quarter to one-sixth of the height of the cylinder 1. Water is passed into the upper cavity 4. Selecting an upper cavity 4 of an appropriate height provides a suitable location for the arrangement of the second air outlet 9 in the lower cavity 5.

[0034] Preferably, the second air outlets 9 are arranged in rows, and in each row of second air outlets 9, the second air outlets 9 are arranged asymmetrically with the axis of the cylinder 1 as the symmetry line. A nozzle is provided corresponding to each second air outlet 9. Since the nozzles are asymmetrically arranged along the center point on the same horizontal plane, the water flow sprayed from the nozzles flows to the inner wall surface of the cylinder 1, rather than the second air outlet 9, thereby achieving the function of flushing the inner wall of the cylinder 1. Since the water flowing down from the top of the second air outlet 9 has an uneven flow rate when flowing to the second air outlet 9, the water column sprayed from the nozzle is also different and can flow to different positions of the inner wall of the cylinder 1. In addition, by adjusting the gas flow rate in the nozzle, it is also possible to flow to different positions of the inner wall of the cylinder 1, thereby flushing the inner wall of the cylinder 1 at different positions. The second air outlets 9 are arranged in rows. The second air outlets 9 are arranged in multiple rows, and each second air outlet 9 is provided with a nozzle, which can flush different positions of the inner wall of the cylinder 1.

[0035] like Figure 3 As shown, this embodiment also provides a method for cleaning a dye liquor preparation device, comprising:

[0036] 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 water outlet of the upper cavity 4 and flows downward along the inner wall of the cylinder 1.

[0037] Step 20: When the level of the water deposited in the cylinder 1 partially submerges the coil 2, turn off the water pump 11, turn on the air pump 7, and flush the coil 2 through the first air outlet 8; then open the drain port to drain the liquid.

[0038] Step 30: Close the drain port, turn on the water pump 11 and the air pump 7, introduce water from the water source 10 into the upper cavity 4, and the water flows out from the water outlet of the upper cavity 4 and flows downward along the inner wall of the cylinder 1; when the liquid level of the water deposited 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 flush the cylinder 1 and the coil 2; then open the drain port to discharge the liquid.

[0039] In the above method, the inner wall of the cylinder 1 is initially cleaned. In step 10, water flows out of the water outlet of the upper chamber 4 and flows downward along the inner wall of the cylinder 1. As the water flows downward, the inner wall of the cylinder 1 is flushed. The lower part of the cylinder 1 collects the flowing water.

[0040] Next, the coil 2 is cleaned. In step 20, when the level of the water deposited in the cylinder 1 partially submerges the coil 2, the water pump 11 is turned off, the air pump 7 is turned on, and the coil 2 is flushed using the first air outlet 8. The drain port is then opened to drain the liquid. The water deposited 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 residual dye to break away from the outer wall and fall into the water. The other part of the gas impacts the water accumulated at the bottom of the cylinder 1, flushing the outer wall of the coil 2 with the water, causing some residual dye to fall into the water. In this way, in step 20, the outer wall of the coil 2 is flushed simultaneously with air and water flow, achieving cleaning of the coil 2. If only air flow is used for flushing, it is difficult for the air flow to reach the inner wall of the coil 2. If only water flow is used for flushing, the impact force of the water flow is not as strong as that of direct air flow. Preferably, flushing the coil 2 using the first air outlet 8 includes: directing a portion of the gas blown out of the first air outlet 8 to drive the liquid flow, thereby flushing the residual dye liquid on the surface of the coil 2; and directing another portion of the gas blown out of the first air outlet 8 toward the surface of the coil 2, thereby flushing the residual dye liquid on the surface of the coil 2. In this way, the water flow impacts the entire outer surface of the coil 2, while the air flow directly impacts the surface of the coil 2. Both of these processes act simultaneously on the coil 2, interacting to clean the coil 2. Since the waste liquid contains the most dye after the first cleaning, the drain port is opened to discharge the waste liquid.

[0041] Finally, the entire inner wall of cylinder 1 is cleaned again. In step 30, the drain port is closed, and water pump 11 and air pump 7 are turned on. Water from water source 10 is introduced into upper chamber 4. Water flows out of the water outlet of upper chamber 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 second air outlet 9, it is sprayed onto the inner wall of cylinder 1 through a nozzle, realizing another method of rinsing the inner wall of cylinder 1. When the liquid level of the water deposited in cylinder 1 reaches the middle of cylinder 1, the liquid level is above second air outlet 9. Water pump 11 is turned off, and cylinder 1 and coil 2 are rinsed using first air outlet 8 and second air outlet 9. The first air outlet 8 discharges gas, stirring the water flow at the bottom of cylinder 1. The second air outlet 9 discharges gas, stirring the water flow in the middle of cylinder 1. In this way, the water is blown by the gas at both the top and bottom, achieving flow. During the flow process, the inner wall of cylinder 1 and the coil are rinsed again. After flushing is completed, open the drain port and drain the liquid.

[0042] In the above scheme, after step 20 is completed, the process can return to step 10 and cycle through steps 10 and 20. This allows most of the remaining dye to be flushed into the water flow, and then proceed to step 30.
