Abstract
Description
Technical Field
[0001] This utility model relates to the field of wool raw material processing technology, and in particular to a dehumidification mechanism for wool drying. Background Technology
[0002] Between the time the wool raw material is sheared from the sheep and the time it enters the textile workshop for combing, spinning and other operations, it needs to be cleaned to remove impurities such as mud, sand and grass seeds, as well as the grease on the surface of the wool. After cleaning, the wet wool raw material also needs to be dried to remove moisture.
[0003] When drying wool after washing, the temperature is best controlled at around 50℃. This is because too low a temperature will affect dehumidification efficiency, while too high a temperature, especially above 60℃, will cause the edges of the wool scales to curl and harden. Furthermore, the previous washing process opens the gaps between the scales, and high-temperature drying causes excessive cross-linking of disulfide bonds, leading to decreased breaking strength and an imbalance in fiber moisture regain. Additionally, when drying wet wool raw materials, it is best to control the moisture content of the wool raw materials at 16.5±0.5%. Over-drying (moisture content <15%) will cause static electricity and fly hair during combing.
[0004] Currently, the main method for drying washed wool is through circulating hot air drying, which is both low-cost and efficient. However, it's best to spread out the wet wool as much as possible before using circulating hot air dehumidification. Otherwise, the accumulation of wet wool will make it difficult for hot air to penetrate the piled-up wool, resulting in uneven drying inside and out, with the outside being over-dried while the inside remains damp. Spreading out the wet wool is time-consuming, labor-intensive, and takes up a lot of space. Utility Model Content
[0005] In view of this, the purpose of this utility model is to propose a dehumidification mechanism for wool drying, so as to solve the technical problem that hot air drying in the prior art easily leads to uneven drying inside and outside of wool raw materials.
[0006] To achieve the above objectives, this utility model provides a dehumidification mechanism for drying wool, including a drying chamber for drying and dehumidifying washed wool, and the dehumidification mechanism further includes:
[0007] A vacuum tube is fixedly connected to the top of the drying chamber. The inner end of the vacuum tube is connected to the inner cavity of the drying chamber, and the outer end of the vacuum tube is connected to an external vacuum pump for evacuating the inner cavity of the drying chamber.
[0008] A hanging rod fixedly connected to the drying chamber is used to hang the washed wool. The hanging rod is a hollow tubular component with circulating water flowing inside.
[0009] The hot water circulation mechanism located at the bottom of the drying chamber is used to heat the circulating water and drive the circulating water to flow through the hanging rod.
[0010] Furthermore, a filter plate is fixedly connected to the top of the drying chamber for filtering wool fibers. The filter plate is located at the connection between the vacuum tube and the drying chamber.
[0011] Furthermore, the two ends of the hanging rod are fixedly connected to the connectors, and the connectors at both ends of the hanging rod are respectively fixedly connected to the left and right side walls of the drying chamber.
[0012] Furthermore, the hanging rods are arranged in several groups from top to bottom, and each group has multiple rods.
[0013] Furthermore, the hot water circulation mechanism includes a heating water tank, which is connected to the inner cavity of the hanging rod, and the heating water tank is also equipped with an electric heater and a booster pump.
[0014] Furthermore, the connector has an internal channel, through which the heating water tank communicates with the inner cavity of the hanging rod.
[0015] Furthermore, the outlet end of the booster pump is connected to the internal channel of one of the connectors, while the internal channel of the other connector is connected to the heating water tank with a one-way valve.
[0016] Furthermore, the hot water circulation mechanism is provided with a base plate at the top, and the drying chamber cavity below the base plate is set as a completely sealed circulating hot water chamber, and the hot water circulation mechanism is located in the circulating hot water chamber.
[0017] Furthermore, the opening of the drying chamber is provided with a sealed door, and a rubber gasket is provided at the opening of the drying chamber. A corresponding rubber gasket is also provided on the inner side of the sealed door.
[0018] The beneficial effects of this utility model are as follows: 2. By setting up a drying chamber to dry and dehumidify the washed wool, and by vacuuming the inside of the drying chamber, the evaporation rate of moisture in the wool is greatly improved, and the dehumidification efficiency is improved. In addition, rubber gaskets are set on the drying chamber and the sealing door to ensure the internal sealing of the drying chamber after the sealing door is closed.
[0019] 2. Multiple hanging rods are installed inside the drying chamber to hang the washed wool. Hot circulating water, set at approximately 50℃, flows through these rods. A hot water circulation mechanism at the bottom of the drying chamber heats the circulating water and drives its circulation within the rods. This ensures the temperature inside the drying chamber is maintained stably at around 50℃. Combined with vacuum dehumidification, this not only ensures high dehumidification efficiency but also provides even dehumidification of the washed wool, preventing localized over-drying.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.
[0028] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.
[0029] The first aspect of this utility model is as follows: Figure 1 , Figure 2 and Figure 3 As shown, when drying and dehumidifying wet wool raw materials, it is best to control the moisture content of the wool raw materials at 16.5±0.5%. Over-drying (moisture content <15%) will cause static electricity and fly hair during combing. At present, the main method for drying wool after washing is to use circulating hot air. However, it is difficult for hot air to penetrate into the interior of wet wool, resulting in uneven drying of the raw materials inside and out, with the outside being over-dried while the inside remains relatively damp. Therefore, this utility model designs a drying chamber 101 for drying and dehumidifying washed wool.
[0030] Specifically, a vacuum tube 103 is fixedly connected to the top of the drying chamber 101. The inner end of the vacuum tube 103 is connected to the inner cavity of the drying chamber 101, and the outer end of the vacuum tube 103 is connected to an external vacuum pump for evacuating the inner cavity of the drying chamber 101.
[0031] In addition, a sealing door 102 is provided at the opening of the drying chamber 101, and a rubber gasket is provided at the opening of the drying chamber 101. A rubber gasket is also provided at the corresponding position on the inner side of the sealing door 102.
[0032] Vacuuming the inside of the drying chamber 101 can greatly improve the evaporation rate of moisture in the wool and improve the dehumidification efficiency. In addition, rubber gaskets are installed on the drying chamber 101 and the sealing door 102 to ensure the internal sealing of the drying chamber 101 after the sealing door 102 is closed.
[0033] Preferably, a filter plate 104 is also fixedly connected to the top of the drying chamber 101 for filtering wool fibers, and the filter plate 104 is located at the connection between the vacuum tube 103 and the drying chamber 101.
[0034] The second aspect of this utility model is as follows: Figure 1 , Figure 2 and Figure 3 As shown, relying solely on vacuuming results in relatively low dehumidification efficiency. Furthermore, when drying wool, the temperature is best controlled at around 50℃. Too low a temperature will affect dehumidification efficiency, while too high a temperature, especially above 60℃, will cause the edges of the wool's scales to curl and harden. Additionally, the preceding washing process will open the scale gaps, and high-temperature drying will cause excessive cross-linking of disulfide bonds, leading to decreased breaking strength and an imbalance in fiber moisture regain. Therefore, this embodiment also includes a hanging rod 107 inside the drying chamber 101 for hanging the washed wool. The hanging rod 107 is fixedly connected inside the drying chamber 101 and is a hollow tubular component with circulating water flowing inside.
[0035] Both ends of the hanging rod 107 are fixedly connected to the connector 106, and the connectors 106 at both ends of the hanging rod 107 are respectively fixedly connected to the left and right side walls of the drying chamber 101. Several groups of hanging rods 107 are arranged from top to bottom, and each group has multiple rods.
[0036] In addition, a hot water circulation mechanism is provided at the bottom of the drying chamber 101 to heat the circulating water and drive the circulating water to flow in the hanging rod 107.
[0037] Specifically, the hot water circulation mechanism includes a heating water tank 109, which is connected to the inner cavity of the hanging rod 107. The heating water tank 109 is also equipped with an electric heater 110 and a booster pump 111. The top of the hot water circulation mechanism is provided with a base plate 108, and the cavity of the drying chamber 101 below the base plate 108 is set as a completely sealed circulating hot water chamber 105. The hot water circulation mechanism is located in the circulating hot water chamber 105.
[0038] Multiple hanging rods 107 are installed inside the drying chamber 101 to hang the washed wool. Hot circulating water circulates inside the hanging rods 107, with the water temperature set at approximately 50℃. A hot water circulation mechanism at the bottom of the drying chamber 101 heats the circulating water and drives its circulation within the hanging rods 107. This ensures that the temperature inside the drying chamber 101 is stably maintained at around 50℃. Combined with vacuuming, this not only ensures high dehumidification efficiency but also allows for even dehumidification of the washed wool, preventing localized over-drying.
[0039] Additionally, a channel is provided inside the connector 106, through which the heating water tank 109 communicates with the inner cavity of the hanging rod 107. The outlet end of the booster pump 111 communicates with the inner channel of one side of the connector 106, while a one-way valve 112 is provided at the connection between the inner channel of the other side of the connector 106 and the heating water tank 109. The one-way valve 112 is provided to prevent the circulating water from flowing back, ensuring that the circulating water inside all the hanging rods 107 flows in the same direction.
[0040] In summary, this invention uses a drying chamber 101 to dry and dehumidify the washed wool. The interior of the drying chamber 101 is vacuumed, significantly increasing the evaporation rate of moisture from the wool and improving dehumidification efficiency. Rubber gaskets are installed on the drying chamber 101 and the sealing door 102 to ensure the internal airtightness of the drying chamber 101 when the sealing door 102 is closed. Multiple hanging rods 107 are installed inside the drying chamber 101 to hang the washed wool, and hot circulating water flows through the hanging rods 107. The temperature of this circulating water is set at approximately 50°C. A hot water circulation mechanism at the bottom of the drying chamber 101 heats the circulating water and drives its circulation within the hanging rods 107. This ensures that the temperature inside the drying chamber 101 is stably maintained at approximately 50°C. Combined with vacuuming, this not only ensures high dehumidification efficiency but also allows for uniform dehumidification of the washed wool, preventing localized over-drying.
