Description
Technical Field
[0001] This utility model relates to the field of refined cotton processing technology, specifically to a temperature-adjustable drying device for refined cotton production. Background Technology
[0002] Refined cotton refers to a uniform, loose, white, fluffy substance free of impurities such as wood chips, bamboo chips, mud, oil, and metal. The raw material for refined cotton is cotton linters, and its main chemical components are cellulose, lignin, and hemicellulose. Refined cotton is non-toxic, odorless, and easily absorbs water. It is a major material for manufacturing ether cellulose, nitrocellulose, and cellulose acetate. The production process of refined cotton requires steaming, hot washing, and cold washing, so it needs to be dried in subsequent processing.
[0003] Currently, steam or hot air is commonly used to dry refined cotton after it has been cooked. However, refined cotton often carries a lot of moisture after washing. Directly drying refined cotton with a lot of moisture will increase the drying time and affect the drying efficiency. Utility Model Content

[0027] Please see Figure 1-5 This utility model provides a technical solution: a temperature-adjustable drying device for refined cotton production, including a shell 1, a feeding hopper 2, a partition plate 3, a dewatering cylinder 4, a motor 5, a drive wheel 6, a driven wheel 7, a drying cylinder 8, a discharge pipe 9, a cylinder 10, a heating wire 11, and an auger 12.
[0028] This device has a pre-dehydration effect, specifically:
[0029] The outer shell 1 is a hollow cylindrical structure. A feed hopper 2 is installed through the upper surface of the outer shell 1. A partition plate 3 is installed inside the outer shell 1, dividing the outer shell 1 into upper and lower chambers. A dewatering structure is installed inside the outer shell 1.

The lower end of the dewatering cylinder 4 passes through the partition plate 3. On the surface of the shell 1, a valve is provided at the lower end of the dehydration cylinder 4 to control its opening and closing. A motor 5 is fixedly installed on the upper surface of the shell 1. The output end of the motor 5 extends through the surface of the shell 1 and into the interior of the shell 1. The output end of the motor 5 is connected to a drive wheel 6, which is a gear structure. Two drive wheels 6 are connected to the output end of the motor 5. A driven wheel 7 is provided on the outer surface of the dehydration cylinder 4. The driven wheel 7 is a gear structure and meshes with the drive wheel 6. A water outlet is provided on the surface of the shell 1, and the water outlet on the surface of the shell 1 is located above the partition plate 3.
[0030] like Figure 1 , Figure 2 and Figure 3 As shown, when using this device, refined cotton is fed into the device from the feed hopper 2 and falls into the dewatering cylinder 4. The motor 5 is started, and the motor 5 drives the drive wheel 6 to rotate. The drive wheel 6 drives the driven wheel 7 to rotate, and the rotating driven wheel 7 drives the dewatering cylinder 4 to rotate. Thus, the refined cotton in the dewatering cylinder 4 undergoes a dewatering process under the action of centrifugal force. The water in the refined cotton is discharged from the water outlet on the surface of the dewatering cylinder 4 and from the water outlet on the surface of the outer shell 1. The valve at the lower end of the dewatering cylinder 4 is activated to send the dewatered refined cotton into the drying cylinder 8.
[0031] This device achieves a uniform drying effect, specifically:
[0032] The outer shell 1 has an internal drying structure, which includes a drying cylinder 8 for drying refined cotton. The drying structure includes a drying cylinder 8, which is an open cylindrical structure. The upper part of the drying cylinder 8 is fixedly connected to the lower surface of the partition plate 3, and the drying cylinder 8 encloses the lower end of the dewatering cylinder 4.

An auger 12 is provided on the outer surface of the cylinder 10. Long strip-shaped ventilation holes are provided on the surface of the drying cylinder 8. The heating wire 11 is fixedly installed on the inner wall of the drying cylinder 8.
[0033] like Figure 1, Figure 3 , Figure 4 and Figure 5 As shown, refined cotton enters the drying cylinder 8 from the lower end of the dewatering cylinder 4 and falls onto the surface of the auger 12 inside the drying cylinder 8. The heating wire 11 is activated, and the heating wire 11 inside the cylinder 10 and the inner wall of the drying cylinder 8 can heat the air inside the drying cylinder 8, thereby drying the refined cotton. During the start-up of the motor 5, the motor 5 drives the drive wheel 6 below to rotate, the drive wheel 6 drives the driven wheel 7 to rotate, the driven wheel 7 drives the discharge pipe 9 to rotate, the discharge pipe 9 drives the cylinder 10 to rotate, thereby driving the auger 12 to rotate, conveying the refined cotton from the top of the drying cylinder 8 to the discharge pipe 9 and the discharge device, and drying it evenly during the conveying process.
[0034] Working principle: When using this temperature-adjustable drying device for refined cotton production, refined cotton is fed into the device from the feed hopper 2. The refined cotton falls into the dewatering cylinder 4. The motor 5 is started, and the motor 5 drives the drive wheel 6 to rotate. The drive wheel 6 drives the driven wheel 7 to rotate, and the driven wheel 7 drives the dewatering cylinder 4 to rotate. Inside the rotating dewatering cylinder 4, the refined cotton is thrown out of the water by centrifugal force. The dewatered refined cotton falls into the drying cylinder 8. The drying cylinder 8 is equipped with a hollow cylinder 10. Heating wires 11 are installed inside the cylinder 10 and on the inner wall of the drying cylinder 8. The heating wires 11 are started to heat the air inside the drying cylinder 8. An auger 12 is installed on the outer surface of the cylinder 10 of the drying cylinder 8. The rotating cylinder 10 drives the auger 12 to rotate, conveying the refined cotton from top to bottom inside the drying cylinder 8. At the same time as drying, the refined cotton is sent out from the discharge pipe 9 at the bottom of the drying cylinder 8, which increases the overall practicality.
