Description

A textile air conditioning insulation system Technical Field

[0001] This invention relates to the field of air conditioning insulation technology, specifically to an air conditioning insulation system for textiles. Background Technology

[0002] Textile products are manufactured from textile fibers and are divided into two main categories: woven fabrics and knitted fabrics. Drying is necessary during the manufacturing process. Air conditioning and insulation systems are common heating systems in the fiber textile industry. Textile products can change the physical properties of fibers through temperature variations. The normal humidity range for textiles is 65%~75%RH. Different textile workshops have different humidity requirements. In textile and chemical fiber workshops, humidity must be maintained between 50%~70%RH to ensure the production of high-quality products. If the humidity is below the required range, it can lead to severe static electricity. Most existing drying systems spray water vapor generated by a steam generator onto the fiber bundles through steam pipes, resulting in imprecise humidity control of textile products and potential damage to the fiber bundle surface, thus reducing fiber quality. Summary of the Invention

[0003] This invention proposes an air conditioning and insulation system for textiles, which solves the problem in related technologies where inaccurate humidity control during heating and drying of textile products leads to steam being sprayed directly onto the fiber bundles, causing damage to the fiber bundle surface and reducing the quality of textile products.

[0027] A water vapor release pipe is provided, wherein the water vapor inlet pipe passes through the top of the mixing shell and is connected to the water vapor release pipe, and the water vapor release pipe is provided with multiple water vapor release holes;

[0029] Based on the aforementioned solution, preferably, the hybrid component includes:

[0030] A mixing shaft is disposed inside the mixing housing, and the mixing shaft has a first cavity.

[0031] A heating shaft is sleeved on the mixing shaft, and the heating shaft has a second cavity.

[0043] The cooling water pipe has two cooling water pipes installed on it. The two cooling water pipes are spiral in shape and connected by a connecting pipe. The output end of the cooling water pipe is connected to a discharge pipe.

[0044] A water supply pipe, wherein the cooling water pipe is connected to the water pump through the water supply pipe.

[0045] The working principle and beneficial effects of this invention are as follows:

[0046] 1. In this invention, when this device is installed in other equipment by installing a hot air mechanism, the blocking plate is welded to the heating shell to fix the support frame. Then, hot water enters the radiator through the inlet pipe and enters other radiators through the connecting pipe. The radiator heats the air around the heating shell. The hot air is blown towards the textile products through the air inlet pipe. After the water temperature in the radiator drops, it is discharged through the water outlet pipe. This cycle continues. The temperature of the water vapor is maintained by blowing hot air towards the water vapor.

[0047] 2. In this invention, by installing a blower mechanism, hot air from the heating housing enters the mixing housing through the blower pipe, and the hot air can be evenly blown into the mixing housing through the air guide opening on the blower cover. When the temperature is too high, the water pump starts and supplies water to the cooling water pipe through the water supply pipe to cool the hot air in the cooling air pipe. The water in the two cooling water pipes flows through the connecting pipe, or the water pump injects the water remaining in the mixing housing into the cooling water pipe to cool the hot air in the cooling air pipe. After the cooled air enters the mixing housing, it mixes with the hot air and lowers the overall temperature, thus accurately controlling the heating temperature and improving the production quality of textile products.

[0048] 3. In this invention, by installing a mixing mechanism, the steam generator introduces water vapor into the water vapor release pipe through the water vapor inlet pipe. The water vapor is then released into the mixing shell through the water vapor release hole. The amount of water vapor released is controlled by adjusting the first electric valve. Hot air and water vapor enter the mixing shaft through the mixing branch pipe, and then enter the spray shell through the spray pipe to heat and dry the textile products. In order to prevent hot air from entering the heating shaft during the transmission process or to ensure the heating temperature, the hot air in the heating shell enters the heating shaft through the heating branch pipe to heat the water vapor in the mixing shaft. When heating and drying different products, the second electric valve is opened to allow some water vapor to enter the spray pipe through the intercepting pipe. Because the drying shell is equipped with a partition, the drying shell is divided into a high humidity heating and drying chamber and a low humidity heating and drying chamber, which ensures the mixing efficiency of water vapor and hot air and can heat and dry different textile products according to their humidity requirements.

[0049] 4. In this invention, by installing a hot air mechanism, a blower mechanism, and a mixing mechanism in coordination, the problem of inaccurate humidity control during the heating and drying of textile products in related technologies is solved, which leads to the steam pipe spraying directly onto the fiber bundle, causing damage to the surface of the fiber bundle and reducing the quality of textile products.

The heating shell 1 is finned and has an air inlet pipe. The hot air mechanism consists of two sets, which are located inside the heating shell 1 to heat the surrounding air. The mixing mechanism is located on one side of the heating shell 1 and is used to mix the hot air from the hot air mechanism with water vapor for heating. The heating shell 1 is connected to the mixing mechanism via the blower mechanism to blow hot air into the mixing mechanism. The hot air mechanism heats the air inside the heating shell 1, and then the blower mechanism blows the hot air into the mixing mechanism to mix it with water vapor for further heating and drying.

[0065] Specifically, the hot air mechanism includes: a support frame 3, support plates 4, threaded rods 5, blocking plates 6, and a heat dissipation assembly.

On the support frame 3, the inlet pipe 8 is connected to the input end of one of the radiators 7, and the outlet pipe 9 is connected to the output end of one of the radiators 7. The input and output ends of multiple radiators 7 are connected through the connecting pipe 10. When this device is installed in other devices, the blocking plate 6 is welded to the heating shell 1 to fix the support frame 3. Then, hot water enters the radiator 7 through the inlet pipe 8 and enters other radiators 7 through the connecting pipe 10. The radiator 7 heats the air around the heating shell 1. The hot air is blown towards the textile products through the air inlet pipe. After the water temperature in the radiator 7 drops, it is discharged through the outlet pipe 9. This cycle continues, and the temperature of the water vapor is maintained by blowing hot air towards the water vapor.

The cooling water pipes 33 are connected by the connecting pipe 34, and the output end of the cooling water pipes 33 is connected to the discharge pipe 35. The cooling water pipes 33 are connected to the water pump 31 through the water supply pipe 36. The hot air in the heating shell 1 enters the mixing shell 11 through the air blowing pipe 27, and the hot air can be blown evenly into the mixing shell 11 through the air guide opening on the air blowing hood 28. When the temperature is too high, the water pump 31 starts and cools the hot air in the cooling air pipe 29 by supplying water to the cooling water pipes 33 through the water supply pipe 36. The water in the two cooling water pipes 33 flows through the connecting pipe 34, or the water pump 31 injects the water remaining in the mixing shell 11 into the cooling water pipes 33 to cool the hot air in the cooling air pipe 29. After cooling, the air enters the mixing shell 11 and mixes with the hot air to reduce the overall temperature. The heating temperature is precisely controlled, which improves the production quality of textile products.

Because the drying housing 23 is equipped with a partition 24, the drying housing 23 is divided into a high humidity heating and drying chamber and a low humidity heating and drying chamber, which ensures the mixing efficiency of water vapor and hot air and can heat and dry different textile products according to their humidity requirements.

[0068] In this embodiment, the working principle of the textile air conditioning insulation system is as follows: When installing this device into other equipment, the blocking plate 6 is welded to the heating shell 1 to fix the support frame 3. Then, hot water enters the radiator 7 through the inlet pipe 8 and enters other radiators 7 through the connecting pipe 10. The radiators 7 heat the air around the heating shell 1. The hot air is blown towards the textile products through the air inlet pipe. After the water temperature in the radiator 7 drops, it is discharged through the outlet pipe 9. This cycle continues. The hot air in the heating shell 1 enters the mixing shell 11 through the air blowing pipe 27, and the hot air can be evenly blown into the mixing shell 11 through the air guide opening on the air blowing hood 28. When the temperature is too high, the water pump 31 starts and supplies water to the cooling water pipe 33 through the water supply pipe 36 to cool the hot air in the cooling air pipe 29. The water in the two cooling water pipes 33 flows through the connecting pipe 34, or the water pump 31 injects the water remaining in the mixing shell 11 into the cooling water pipe 33. The hot air in the cooling duct 29 is cooled down. The cooled air enters the mixing shell 11 and mixes with the hot air to lower the overall temperature.

The hot air and water vapor enter the mixing shaft 18 through the mixing branch pipe 20, and then enter the spray shell through the spray pipe 25 to heat and dry the textile products. In order to prevent the hot air from being transported or to ensure the heating temperature, the hot air in the heating shell 1 enters the heating shaft 19 through the heating branch pipe 22 to heat the water vapor in the mixing shaft 18. When heating and drying different products, the second electric valve 17 is opened to allow some water vapor to enter the spray pipe 25 through the intercepting pipe 16. Because the drying shell 23 is equipped with a partition 24, the drying shell 23 is divided into a high humidity heating and drying chamber and a low humidity heating and drying chamber.
