Description

Technical Field

[0001] This utility model relates to the field of dyeing and singeing machine technology, specifically to an automatic temperature control device for cooling water in dyeing and singeing machines. Background Technology

[0002] In dyeing and printing production, the singeing machine is an indispensable and important machine. During normal production, the singeing nozzle and the cold water roller must be cooled with cooling water; otherwise, the nozzle and the cold water roller will deform and become unusable.

[0003] When the singeing machine uses the city water supply as the water source for the singeing burner and the cold water roller, the surface of the cold water roller will condense (sweat) due to the large temperature difference. During the singeing process to remove the fuzz, the fabric will have carbon ash on its surface. When the fabric passes through the cold water roller, the surface of the cold water roller will form sticky dust, causing the fabric surface to become dirty, which is a quality problem that has not been completely solved. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes an automatic temperature control device for cooling water in a dyeing and finishing machine. By controlling the water temperature, it avoids the phenomenon of fabric sticking during the singeing process, improves the quality and efficiency of fabric production, and effectively saves production resources.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: an automatic temperature control device for cooling water in a singeing machine, comprising a water supply pipe, a singeing machine, and a cooling water return collection tank.

The singeing nozzle 6 and the cold water roller 7 are connected to the cooling water return collection tank 3 via a first pipe 8. A water storage tank 9 is installed on one side of the singeing machine 2, and the water supply pipe 1 is connected to the water storage tank 9. The bottom of the water storage tank 9 is connected to the singeing nozzle via a second pipe 10. 6 is connected to the cooling water roller 7. The second pipe 10 is equipped with a third control valve 11. The cooling water collection tank 3 is connected to the cooling water pipe 13 through the fourth control valve 12. The water storage tank 9 is also equipped with a liquid level control system 14 and a temperature control system 15. The liquid level control system 14 is connected to the water supply pipe 1 through a pneumatic ball valve 16. The temperature control system 15 is connected to the cooling water pipe 13 through a pneumatic three-way valve 17. One end of the pneumatic three-way valve 17 extends into the water storage tank 9 through the fifth pipe 18.

[0023] The liquid level control system 14 includes a liquid level sensor 19, which is connected to a first intelligent light column controller 20. The first intelligent light column controller 20 is connected to a first electromagnetic pneumatic valve 21, which is controlled by a pneumatic ball valve 16 on the water supply pipeline 1.

[0024] The temperature control system 15 includes a temperature sensor 22, which is connected to a second intelligent light bar controller 23. The second intelligent light bar controller 23 is connected to a second electromagnetic pneumatic valve 24, which is controlled by a pneumatic three-way valve 17 on the cooling water return pipe 13.

[0025] Both the first electromagnetic pneumatic valve 21 and the second electromagnetic pneumatic valve 24 are connected to the compressed air intake pipe 27.

[0026] The volume of water storage tank 9 is 10~20 m³. 3 .

[0027] Several singeing nozzles 6 and cooling water rollers 7 are provided.

[0028] The first intelligent light column controller 20 sets the liquid level height parameter when water enters the water storage tank 9. The liquid level height is set to be 0.5 ~ 1.0 m from the top of the water storage tank 9. When the liquid level of the cooling water in the water storage tank 9 is greater than 1.0 m from the top of the water storage tank 9, the first electromagnetic pneumatic valve 21 controls the pneumatic ball valve 16 to open, and the water in the water supply pipe 1 flows into the water storage tank 9. When the liquid level reaches 0.5 m from the top of the water storage tank 9, the pneumatic ball valve 16 closes.

[0029] The second intelligent light column controller 23 sets the cooling water temperature parameters in the water storage tank 9. The water temperature is set to 36~38℃. When the temperature of the cooling water in the water storage tank 9 is higher than 38℃, the second electromagnetic pneumatic valve 24 controls the pneumatic three-way valve 17 to close one end connected to the water storage tank 9. When the temperature of the cooling water in the water storage tank 9 is lower than 36℃, the second electromagnetic pneumatic valve 24 controls the pneumatic three-way valve 17 to open one end connected to the water storage tank 9.

[0030] The second pipe 10 is equipped with a first centrifugal water pump 25, and the cooling return water pipe 13 is equipped with a second centrifugal water pump 26.

[0031] Working principle:

[0032] A 10-20 m³ water storage tank 9 is installed on one side of the singeing machine 2. A liquid level sensor 19 and a temperature sensor 22 are installed on the water storage tank 9. The cooling water level in the water storage tank 9 is set on the first intelligent light column controller 20. When the distance from the top of the water storage tank 9 is greater than 1.0 m, the first electromagnetic pneumatic valve 21 controls the pneumatic ball valve 16 to open, and water from the water supply pipe 1 flows into the water storage tank 9. When the liquid level reaches 0.5 m from the top of the water storage tank 9, the pneumatic ball valve 16 closes, so that the cooling water level in the water storage tank 9 is always within the control range.

[0033] The temperature of the cooling water in the storage tank 9 is set on the second intelligent light column controller 23. The temperature parameter is set to 36~38 ℃. When the temperature of the cooling water in the storage tank 9 is higher than 38 ℃, the second electromagnetic pneumatic valve 24 controls the pneumatic three-way valve 17 to close one end connected to the storage tank 9. The cooling return water is lifted by the second centrifugal water pump 26 and discharged to the centralized pool through the pneumatic three-way valve 17. After being cooled in the centralized pool, it enters the storage tank 9 through the water supply pipe 1. When the temperature of the cooling water in the storage tank 9 is lower than 36 ℃, the second electromagnetic pneumatic valve 24 controls the pneumatic three-way valve 17 to open one end connected to the storage tank 9. The cooling return water is lifted by the second centrifugal water pump 26 and flows into the storage tank 9. The liquid level control system 14 and temperature control system 15 installed on the water storage tank 9 ensure the temperature of the cooling water entering the singeing burner 6 and the cold water roller 7 of the singeing machine, thus completely solving the equipment defect of dirt sticking to the cold water roller of the singeing machine, meeting the requirements of the production process for the cleanliness of the equipment guide roller, solving the problem of dirt sticking in the singeing process of fabric for many years, and the parts of other production processes that have quality hazards caused by condensation (sweating) on ​​the cold water roller can all be modified and solved with reference to this solution.
