Description

Technical Field

[0001] This utility model relates to the field of polymer material manufacturing, and in particular to a drying device for ultra-high molecular weight polyethylene fibers. Background Technology

[0002] Polyethylene fiber is a fibrous material obtained by melt spinning polyethylene. It includes short fibers and filaments. The mechanical strength of this fiber can be adjusted by the spinning process parameters. In the production process of polyethylene fiber, a wet process is often used. Low-volatile substances such as mineral oil and white oil are used as solvents to prepare ultra-high molecular weight polyethylene spinning solution. After the spinning solution is extruded from the spinneret, it enters a water bath to solidify and obtain wet gel filaments containing low-volatile solvents. These fibers need to be dried before they can be spun and used.

[0003] However, existing drying equipment generally uses a combination of hot air blower and conveyor belt. However, this method of drying is usually not in a closed environment, which may cause fibers to fly out of the drying equipment, resulting in waste of fiber raw materials. At the same time, when blowing air is required, the indoor air used by the blower may carry a large number of dust particles, which can easily contaminate the polymer fibers during drying.

[0004] Therefore, a drying device for ultra-high molecular weight polyethylene fibers is provided. Utility Model Content

[0005] In view of the problems existing in the prior art, the present invention is proposed.

[0006] Therefore, this utility model aims to solve the technical problem that existing drying devices, in their non-enclosed drying environment, can contaminate fibers with particulate matter from the ambient air.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a drying device for ultra-high molecular weight polyethylene fibers, comprising a drying component and a hot air component.

[0008] The drying assembly includes a cylindrical structure, a feed inlet structure, and a swinging structure. The feed inlet structure is installed at one end of the cylindrical structure, the swinging structure is fixedly installed on the outside of the feed inlet structure, and the fixed structure is installed at the end of the cylindrical structure away from the feed inlet structure.

[0009] The hot air assembly includes a filter structure, a blower, a connecting pipe, a heater, and a horn tube. The blower is installed on the top of the filter structure, the air outlet of the blower is connected to the connecting pipe, the heater is installed on the connecting pipe, and a horn tube is installed at one end of the connecting pipe, which is connected to the cylindrical structure.

[0010] As a preferred embodiment of the ultra-high molecular weight polyethylene fiber drying device of this utility model, the cylindrical structure includes a drying cylinder, the top of the drying cylinder is provided with an evaporation port, bearings are installed at the connection between the two ends of the cylindrical structure, and a half tooth is installed on one side of the outer wall of the drying cylinder.

[0011] In a preferred embodiment of the ultra-high molecular weight polyethylene fiber drying device of this utility model, the feed port structure includes a mounting block, one end of the feed port structure is provided with a sealing cover, and the mounting block is installed inside the bearing.

[0016] In a preferred embodiment of the ultra-high molecular weight polyethylene fiber drying device of this utility model, a removable protective cover is provided on the outer wall of the mounting box.

[0017] The beneficial effects of this utility model are as follows: The filter structure effectively filters large dust particles in the air, preventing dust from adhering to the fibers and causing fiber contamination. At the same time, the closed drying component provides better heat preservation, eliminating the need to consume a large amount of heat to maintain the temperature of the device, effectively reducing the operating cost of the device. In addition, the evaporation port at the top facilitates the discharge of moisture from the device, increasing the ease of use.

[0029] Example 1

[0030] Reference Figure 1-5 This embodiment provides a drying device for ultra-high molecular weight polyethylene fibers, including a drying component 100 and a hot air component 200.

[0031] The drying assembly 100 includes a cylindrical structure 101, a feed inlet structure 102, and a swing structure 103. The feed inlet structure 102 is installed at one end of the cylindrical structure 101. The feed inlet structure 102 can be used to input moist polymer fibers into the device. The swing structure 103 is fixedly installed on the outside of the feed inlet structure 102. The swing structure 103 can drive the cylindrical structure 101 to swing, thereby making the cylindrical structure 101 sway. A fixing structure 104 is installed at the end of the cylindrical structure 101 away from the feed inlet structure 102. The fixing structure 104 fixes the other end of the cylindrical structure 101 to prevent swaying during operation.

[0032] The hot air assembly 200 includes a filter structure 201, a blower 202, a connecting pipe 203, a heater 204, and a horn pipe 205. The filter structure 201 filters the gas entering the device. The filter structure 201 includes a mounting box 201a, which houses an internal air outlet pipe 201b. The inner wall of the mounting box 201a is provided with the air outlet pipe 201b, which houses a pre-filter 201c and a fine filter 201d. The air outlet pipe 201b is connected to the air inlet of the blower 202. The bottom of the inner wall of the air outlet pipe 201b is equipped with a pre-filter 201c, which performs preliminary filtration of the air. A fine filter 201d is installed above 201c. The fine filter 201d increases the filtration accuracy. The filter uses commercially available filter sponge. A removable protective cover is provided on the outer wall of the installation box 201a. The protective cover can be removed to replace the internal air outlet pipe 201b to maintain the filtration effect. A blower 202 is installed on the top of the filter structure 201. A connecting pipe 203 is installed at the air outlet of the blower 202. A heater 204 is installed on the connecting pipe 203. The heater 204 has a resistance wire inside, which heats the air through resistance heating. A horn pipe 205 is installed at one end of the connecting pipe 203. The horn pipe 205 is connected to the cylindrical structure 101.

[0033] This embodiment has the following workflow: When in use, wet fibers are placed into the cylinder structure 101 through the feed port structure 102, and then the filter structure 201, blower 202 and heater 204 are started. At this time, the blower 202 starts and blows the airflow into the heater 204. The heater 204 heats the gas, and the heated gas enters the cylinder structure 101 to dry the fibers.

[0034] Example 2

[0035] Reference Figure 3-4 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but differs from the previous embodiment in that it provides a drying device for ultra-high molecular weight polyethylene fibers, comprising:

[0036] The cylindrical structure 101 includes a drying cylinder 101a, with an evaporation port 101b at the top. A protective mesh is installed inside the evaporation port 101b to prevent fibers from detaching from the device. Bearings 101c are installed at the connection points of both ends of the cylindrical structure 101, allowing for easy rotation of the cylindrical structure 101. A semi-tooth 101d is installed on one side of the outer wall of the drying cylinder 101a. The feed inlet structure 102 includes a mounting block 102a, with a sealing cover 102b at one end. The sealing cover 102b is hinged to one side wall of the mounting block 102a. The mounting block 102a is mounted on a shaft. Inside the support 101c, the swing structure 103 includes a mounting frame 103a, which is mounted on the outer wall of the mounting block 102a. An electric push rod 103b is fixedly mounted on the crossbar of the mounting frame 103a. The electric push rod 103b is telescopic, thereby pushing the toothed plate 103d to move left and right. A connecting block 103c is mounted on the movable end of the electric push rod 103b. The toothed plate 103d is mounted on the top of the connecting block 103c. The toothed plate 103d meshes with the half tooth 101d. The left and right movement of the toothed plate 103d drives the half tooth 101d to rotate, and the rotation of the half tooth 101d simultaneously drives the drying cylinder 101a to rotate left and right.

[0037] This embodiment has the following workflow: In use, first open the sealing cover 102b, feed the raw material into the drying cylinder 101a, and then close the sealing cover 102b. At this time, the electric push rod 103b extends. When the electric push rod 103b extends, it drives the toothed plate 103d to move left and right. The left and right movement of the toothed plate 103d drives the half tooth 101d to rotate. At this time, the drying cylinder 101a rotates left and right, thereby swinging the fibers inside the drying cylinder 101a.
