Description

Technical Field

[0001] This utility model specifically relates to a water supply and temperature control system for a dyeing process chemical equipment, belonging to the technical field of dyeing process chemical equipment. Background Technology

[0002] After the bundled fabric is processed, it needs to be dyed to improve the richness of the fabric colors. Before dyeing, a chemical treatment device is required to treat the dye, which is a high-concentration dye raw material, and dilute it to a specified volume and concentration to ensure dyeing efficiency. Existing chemical treatment devices, such as the acrylic fiber fabric dyeing chemical treatment device disclosed in Chinese Patent Publication No. CN222524922U, include a chemical treatment tank, a sealed top cover, and a temperature treatment tank. This structure solves the problem that different dye raw materials have different operating methods and water temperature requirements during the chemical treatment process, making it difficult for the device to control them accurately. It also addresses the difficulty in precisely controlling the stirring of solvent and dye raw materials during the process. Due to the large amount of solvent and the large volume of the device, it is difficult to quickly and evenly dissolve and mix the dye with the solvent. However, the above-mentioned chemical mixing device has a complex structure and cannot achieve linkage between the various chemical mixing tanks. In addition, when the chemical mixing device of the existing bead dyeing process is used, the amount of water added can only be estimated manually based on the diameter of the chemical mixing tank and the visual height, resulting in inconsistent concentrations of dye before and after. Furthermore, during the chemical mixing process, it is impossible to control the temperature according to the chemical mixing requirements, and temperature fluctuations will cause large fluctuations in the indicators of dye and dye liquor. In addition, when adding water to the chemical mixing tank during the chemical mixing process, it is easy to cause local quenching inside the chemical mixing tank, resulting in large temperature fluctuations. Utility Model Content

[0003] To address the aforementioned issues, this invention proposes a water supply and temperature control system for the dyeing process material processing device, enabling automated water supply and temperature control for equipment in the dyeing workshop, thereby improving the dyeing stability and quality of the dyeing process.

[0004] The water supply and temperature control system of the dyeing process chemical equipment of this utility model includes:

[0005] A dyeing and finishing process chemical treatment table, on which multiple chemical treatment cylinders and a controller for overall machine control are fixed;

[0006] A water supply unit includes a water supply pipe installed on each chemical tank, the water supply pipe being connected to a solenoid valve; each solenoid valve is connected to a flow meter; the flow meter is connected to the water supply pipe, and the water supply pipe is connected to the inlet water line;

[0007] The heating unit includes a heat exchange coil fixed to the inside of the material processing cylinder, a heating pipe and a return water pipe; one end of the heat exchange coil is connected to the heating pipe through an electric proportional valve, the other end of the heat exchange coil is connected to the return water pipe, the heating pipe is connected to the outlet of the heat medium heating equipment through a pump set, and the return water pipe is connected to the return water outlet of the heat medium heating equipment.

[0008] During operation, the controller adds a fixed amount of water to each material processing cylinder according to the material processing requirements (water-to-material ratio). That is, when the material quantity is the set amount, it can automatically calculate the amount of water to process. The controller responds to the water quantity through solenoid valves and flow meters, accurately injecting a fixed amount of water into the corresponding material processing cylinder. Then, the controller controls the temperature value of each material processing cylinder according to the material processing requirements (temperature control value). That is, the controller can automatically look up the opening value of the electro-proportional valve by looking up the temperature control value of the material processing cylinder. The controller sends the opening value to the electro-proportional valve for opening response, accurately controlling the temperature of each material processing cylinder.

[0009] Furthermore, the chemical tank includes a soaping chemical tank, a boiling chemical tank, a first thinner chemical tank, a second thinner chemical tank, a first indigo chemical tank, a second indigo chemical tank, a sulfur blackening chemical tank, a softener chemical tank, and a small spare sulfur blackening chemical tank arranged in sequence.

[0010] The water supply pipes of the first and second thinning cylinders are respectively connected to the first three-way valve via solenoid valves, and the third end of the first three-way valve is connected to the first flow meter.

[0011] The water supply pipes of the first and second indigo chemical tanks are respectively connected to the second three-way valve via solenoid valves, and the third end of the second three-way valve is connected to the second flow meter;

[0012] The water supply pipes of the vulcanizing and blackening material cylinder and the softener material cylinder are respectively connected to the third flow meter and the fourth flow meter via solenoid valves.

[0013] Furthermore, it also includes a water supply temperature control tank, on the inside of which a heat exchange coil is installed. One end of the heat exchange coil is connected to a heating pipe via an electro-proportional valve, and the other end is connected to a return water pipe. The water supply temperature control tank is connected in series with the water supply pipe and the inlet pipe. A level control valve connected to the inlet pipe is installed inside the water supply temperature control tank. A water supply pump and a pressure equalization valve are connected in series between the water supply temperature control tank and the water supply pipe. A temperature transmitter is installed inside the water supply temperature control tank.

[0014] During the chemical processing, when water needs to be added to a particular chemical processing tank, the temperature of the heat exchange coil in the water supply temperature control tank is controlled based on the current chemical processing temperature of that tank. This is achieved by controlling the opening of the corresponding electro-proportional valve. When the temperature transmitter detects that the current temperature has reached the set temperature, the water pump pumps the heated chemical processing water into the water supply pipe, which then flows through the pipe, flow meter, and solenoid valve to the corresponding chemical processing tank. This allows for precise control of the water supply volume and temperature in the chemical processing tank. After adding water to one chemical processing tank, temperature-controlled water replenishment continues to another tank. Specifically, the temperature transmitter monitors the current temperature in the water supply temperature control tank. If the temperature is lower than the target chemical processing tank temperature, the electro-proportional valve is opened to bring the temperature up to the target tank temperature. If the temperature is higher than the target tank temperature, the level control valve is activated to bring the temperature up to the target tank temperature. When the water level in the water supply temperature control tank is below the low-level line, the level control valve is activated to replenish water.

[0015] Furthermore, a return valve is connected to the water supply pipe, and the return valve is connected to the low-level water supply temperature control tank. After a certain chemical tank is replenished with water, the next chemical tank is replenished. Before replenishment, the return valve is opened, and the chemical water in the water supply pipe is pumped back into the water supply temperature control tank through the return valve. The water supply pump and the return valve are controlled to achieve water circulation between the water supply pipe and the water supply temperature control tank. Then, the return valve is closed, and the temperature-controlled chemical water is pumped into the corresponding chemical tank through the water supply pipe, flow meter and solenoid valve.

[0016] Furthermore, a temperature transmitter is connected in series between the heat exchange coil and the return water pipe. The temperature transmitter monitors the return water temperature of each chemical tank in real time, and the return water temperature is linked with the electric proportional valve for precise control of the chemical tank temperature.

[0017] Compared with the prior art, the water supply and temperature control system of the dyeing process chemical device of this utility model adopts a whole-machine control controller to control each chemical cylinder of the dyeing process chemical device. The controller can accurately control the water replenishment and chemical temperature according to the water inlet requirements and chemical temperature control requirements. Moreover, during the secondary water replenishment process, it will not cause fluctuations in chemical temperature, thereby improving the dyeing stability and dyeing quality of the dyeing process.

Detailed Implementation

[0023] Example 1:

[0024] like Figure 1 and Figure 2 The water supply and temperature control system of the dyeing process chemical equipment shown includes:

[0025] The dyeing and finishing process chemical treatment table 1 is equipped with multiple chemical treatment cylinders 2 and a controller for overall machine control.

[0026] The water supply unit includes a water supply pipe 3 installed on each chemical tank 2, and the water supply pipe 3 is connected to a solenoid valve 4; each solenoid valve 4 is connected to a flow meter 5; the flow meter 5 is connected to a water supply pipe 6, and the water supply pipe 6 is connected to an inlet pipe 7.

[0027] The heating unit includes a heat exchange coil 8 fixed to the inside of the material processing cylinder 2, a heating pipe 9, and a return water pipe 10. One end of the heat exchange coil 8 is connected to the heating pipe 9 through an electro-proportional valve 11, and the other end of the heat exchange coil 8 is connected to the return water pipe 10. The heating pipe 9 is connected to the outlet of the heat medium heating equipment through a pump set 12, and the return water pipe 10 is connected to the return water outlet of the heat medium heating equipment.

[0028] During operation, the controller adds a fixed amount of water to each material processing cylinder 2 according to the material processing requirements (water-to-material ratio). That is, when the material quantity is the set amount, the controller can automatically calculate the amount of water to process. The controller responds to the water quantity through the solenoid valve 4 and the flow meter 5, accurately injecting a fixed amount of water into the corresponding material processing cylinder 2. Then, the controller controls the temperature value of each material processing cylinder 2 according to the material processing requirements (temperature control value). That is, the controller can automatically look up the opening value of the electro-proportional valve 11 by looking up the temperature control value of the material processing cylinder 2. The controller sends the opening value to the electro-proportional valve 11 for opening response, accurately controlling the temperature of each material processing cylinder 2.

[0029] Example 2:

[0030] like Figure 3 The water supply temperature control system of the dyeing process chemical equipment shown also includes a water supply temperature control tank 13. A heat exchange coil 8 is installed inside the water supply temperature control tank 13. One end of the heat exchange coil 8 is connected to the heating pipe 9 through an electro-proportional valve 11, and the other end of the heat exchange coil 8 is connected to the return water pipe 10. The water supply temperature control tank 13 is connected in series with the water supply pipe 6 and the inlet water pipe 7. A level control valve 14 connected to the inlet water pipe 7 is provided inside the water supply temperature control tank 13. A water supply pump 15 and a pressure equalization valve 16 are connected in series between the water supply temperature control tank 13 and the water supply pipe 6. A temperature transmitter 17 is installed inside the water supply temperature control tank 13.

[0031] During the chemical processing, when water needs to be added to a specific chemical processing cylinder 2, the temperature of the heat exchange coil 8 in the water supply temperature control tank 13 is controlled based on the current chemical processing temperature of that cylinder 2. This means controlling the opening of the corresponding electro-proportional valve 11. When the temperature transmitter 17 detects that the current temperature has reached the set temperature, the water supply pump 15 pumps the heated chemical processing water into the water supply pipe 6, which then flows through the water supply pipe 6, flow meter 5, and solenoid valve 4 into the corresponding chemical processing cylinder 2. This allows for precise control of the water supply volume and temperature of the chemical processing cylinder 2. After water is added to one of the chemical tanks 2, temperature-controlled water replenishment continues to be carried out to the other chemical tank 2. Specifically, the temperature in the current water supply temperature control tank 13 is monitored by the temperature transmitter 17. When the temperature value is lower than the target temperature of the chemical tank 2, the opening of the electro-proportional valve 11 is controlled to make its temperature reach the target temperature of the chemical tank 2. When the temperature value is higher than the target temperature of the chemical tank 2, the liquid level control valve 14 is controlled to activate, so that its temperature reaches the target temperature of the chemical tank 2. When the water level in the water supply temperature control tank 13 is lower than the low level line, the liquid level control valve 14 is controlled to replenish water.

[0032] A return valve 18 is connected to the water supply pipe 6, and the return valve 18 is connected to the low-level water supply temperature control tank 13. After a certain chemical tank 2 is replenished with water, the next chemical tank 2 is replenished with water. Before replenishment, the return valve 18 is opened, and the chemical water in the water supply pipe 6 is pumped back into the water supply temperature control tank 13 through the return valve 18. The water supply pump 15 and the return valve 18 are controlled to realize water circulation between the water supply pipe 6 and the water supply temperature control tank 13. That is, the return valve 18 is opened first to empty the inside of the water supply pipe 6, and then water is replenished through the water supply pump 15 to realize water circulation. Then, the return valve 18 is closed, and the temperature-controlled chemical water is pumped into the corresponding chemical tank 2 through the water supply pipe 6, the flow meter 5 and the solenoid valve 4.

[0033] A temperature transmitter 17 is connected in series between the heat exchange coil 8 and the return water pipe 10. The temperature transmitter 17 monitors the return water temperature of each chemical cylinder 2 in real time, and links the return water temperature with the electro-proportional valve 11 to achieve precise control of the temperature of the chemical cylinder 2.
