Description

Technical Field

[0001] This utility model relates to the field of wool processing technology, and in particular to a discharge mechanism for a wool dryer. Background Technology

[0002] After washing, wool needs to be dried at a temperature of around 60 degrees Celsius to ensure that the quality of the wool is not affected. Wool drying generally uses a horizontally arranged drying drum. The wool to be dried is added into the drying drum, and heated air is simultaneously introduced into the drying drum. This heats the wool inside the drum and blows out the moisture generated during drying, thus improving the drying effect. Finally, the dried wool is discharged from the other end of the drying drum onto a belt conveyor and transported to the next process.

[0003] Because the inner wall of the drying drum is equipped with multiple sets of spiral blades in the circumferential direction, the wool can be circumferentially turned over and axially transported, so that the wool is automatically fed onto the conveyor belt. During this process, the wool will clump together in the drying drum, which will not only affect the wool drying efficiency, but also affect subsequent processing due to uneven distribution on the conveyor belt. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a discharge mechanism for a wool dryer to solve the problem that wool clumps in the drying drum, which not only affects the wool drying efficiency, but also affects subsequent processing due to uneven distribution on the conveyor belt.

[0005] To achieve the above objectives, this utility model provides a discharge mechanism for a wool dryer, including an extension frame located at one end of the outside of the drying cylinder;

[0006] The feeding box is fixed on the outer frame, and its top is connected to one end of the drying cylinder.

[0007] A dispersing part for horizontally and radially dispersing clumped wool is provided inside the feeding box. It includes a horizontal shaft that is horizontally and radially rotatable inside the feeding box. Two double helical blades are provided on the outer circumference of the horizontal shaft. The two double helical blades have opposite helical directions. A drive motor is fixedly provided on the outside of the feeding box. The output end of the drive motor passes through one side of the feeding box and is fixedly connected to one end of the horizontal shaft.

[0008] A baffle is fixed to the top of the feeding box and seals one end face of the drying cylinder, and an air outlet groove is provided on it.

[0009] The conveyor, located on the outer frame, is used to carry and transport wool from the feeding box.

[0010] Preferably, the extension frame is located outside the drying cylinder at the end furthest from the air inlet, and the extension frame is located below the drying cylinder.

[0011] Preferably, the feeding box is located vertically between the baffle and the conveyor, and the lower edge of the connection between the feeding box and the drying cylinder is lower than the lower edge of the drying cylinder.

[0012] Preferably, the baffle is provided with a feed inlet, and the feed inlet and the drying cylinder are coaxial.

[0013] Preferably, the outer edge of the double helix blade is uniformly distributed with combing needles, and the height of the top of the double helix blade is less than the height of the lower edge of the drying cylinder.

[0014] Preferably, the discharge mechanism further includes an inner cylinder coaxially disposed inside the drying cylinder. The inner wall of the inner cylinder and the inner wall of the drying cylinder are both provided with single spiral blades. A connecting piece is fixedly disposed between the outer side of the inner cylinder and the inner edge of the single spiral blade inside the drying cylinder. A plurality of material turning strips are fixedly disposed circumferentially on the inner walls of the inner cylinder and the drying cylinder. One end of the inner cylinder is connected to the inside of the drying cylinder through a material passage groove.

[0015] Preferably, the two single helical blades have the same helical direction and the same pitch between them.

[0016] Preferably, the material feed trough is located at the end of the inner cylinder away from the baffle, and the material feed trough is radially distributed opposite to the end of the single spiral blade.

[0017] The beneficial effects of this utility model are:

[0018] This invention, through the feeding box and the conveying part inside it, can disperse the clumped wool along the horizontal radial direction of the drying drum. When the wool is fed, it is more evenly dispersed on the conveyor, reducing the agglomeration rate of the wool after feeding and indirectly reducing the impact on subsequent wool processing. Furthermore, through the mutual cooperation of two layers of single spiral blades arranged in the same direction, the volume of the drying drum can be reduced and the axial space occupancy of the drying drum can be reduced under the premise of the same drying efficiency.

[0028] like Figures 1 to 4 As shown, a discharge mechanism for a wool dryer includes an extension frame 1 located at one end of the exterior of the drying cylinder. The drying cylinder is mounted on a base, and a drive unit for rotating the drying cylinder is provided on the base. The drive unit includes a gear ring fixed to the exterior of the drying cylinder and a gear rotatably mounted on the base. The tooth surfaces of the gear ring and the gear mesh. A servo motor for driving the gear to rotate is provided on the base, thus driving the drying cylinder to rotate. The extension frame 1 is located at the end of the drying cylinder away from the air inlet and is located below the drying cylinder. The extension frame 1 is mounted on the base to avoid affecting the rotation of the drying cylinder. A constant temperature fan is connected to the end of the drying cylinder away from the extension frame 1. The airflow temperature blown by the constant temperature fan into the drying cylinder is 45℃-60℃, used for low-temperature drying of wool.

[0029] The feeding box 2 is fixed on the outer frame 1, and its top is connected to one end of the inside of the drying cylinder so as to hold the dry wool fed from the drying cylinder.

[0030] A dispersion section 5, located within the feeding box 2, is used to horizontally and radially disperse clumped wool. It includes a horizontally rotatable shaft 51 within the feeding box 2. Two double-helix blades 52 are circumferentially arranged on the outer side of the shaft 51. Combing needles are evenly distributed along the outer edge of the double-helix blades 52, and the height of the top of each blade is less than the height of the bottom edge of the drying cylinder. The two double-helix blades 52 have opposite helical directions. A drive motor 53 is fixedly installed outside the feeding box 2. The output end of the drive motor 53 passes through one side of the feeding box 2 and is fixedly connected to one end of the horizontal shaft 51. This design allows the clumped dry wool to be gradually pulled apart towards both ends of the horizontal shaft 51 through the synchronous rotation of the two coaxially rotating double-helix blades 52, achieving axial loosening of the horizontal shaft 51. This significantly reduces the clumping rate of the dry wool during final feeding and improves the uniformity of wool distribution along the horizontal shaft 51 during feeding, reducing the impact of wool clumping on subsequent processing.

[0031] The baffle 3 is fixed to the top of the feeding box 2 and seals one end face of the drying cylinder. It is provided with an air outlet 4 and a feeding port on the baffle 3. The feeding port and the drying cylinder are coaxial. This design can not only prevent wool from leaking out, reduce wool waste rate and maintain the cleanliness of the processing environment, but also efficiently remove airflow and water vapor generated during drying in the drying cylinder.

[0032] The conveyor 6, which is a belt conveyor, is located on the outer frame 1. The feeding box 2 is located vertically between the baffle 3 and the conveyor 6, and the lower edge of the connection between the feeding box 2 and the drying cylinder is lower than the lower edge of the drying cylinder. It is used to carry and transport the wool fed into the feeding box 2. The wool is dispersed through the horizontal radial direction of the dispersing part 5 (which refers to the horizontal radial direction of the drying cylinder) and falls relatively evenly onto the conveyor 6, so as to continuously and relatively evenly transport the dry wool to the next process and avoid the wool from clumping and affecting subsequent processing.

[0033] like Figure 4As shown, the discharge mechanism also includes an inner cylinder 7 coaxially disposed inside the drying cylinder. Both the inner wall of the inner cylinder and the inner wall of the drying cylinder are provided with single spiral blades 8. The spiral directions of the two single spiral blades 8 are the same, and the pitch of the two single spiral blades 8 is also the same. A material passage chute is located at the end of the inner cylinder 7 away from the baffle 3, and the material passage chute is radially opposite to the ends of the single spiral blades 8. A connecting piece 10 is fixedly provided between the outer side of the inner cylinder 7 and the inner edge of the single spiral blades 8 inside the drying cylinder. Several turning strips 9 are fixedly provided circumferentially on the inner walls of the inner cylinder 7 and the drying cylinder. One end of the inner cylinder 7 communicates with the interior of the drying cylinder through the material passage chute, causing the inner cylinder 7 to rotate synchronously while the drying cylinder rotates. During this process, the turning strip 9 rotates synchronously with the drying cylinder and can turn the wool around in all directions, so that the wool is heated evenly and comprehensively. At the same time, the wool can also move along the axis away from the baffle 3 inside the inner cylinder 7 under the push of the single spiral blade 8. Finally, it is discharged from the material chute into the single spiral blade 8 on the inner wall of the drying cylinder and can move along the axis into the lower material box 2. In this way, wet wool can be continuously conveyed into the inner cylinder 7 and dry wool can be continuously conveyed into the lower material box 2, improving the continuity, stability and uniformity of wool conveying to the next process. It can also reduce the axial space occupancy of the drying cylinder without affecting the wool drying efficiency.
