Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, and in particular to a waste drip irrigation tape recycling and drying device. Background Technology

[0002] Recycling waste drip irrigation tape is an important way to turn waste into treasure and solve environmental pollution. When recycling waste drip irrigation tape, it is necessary to manually pick up the waste drip irrigation tape in the field, then crush, wash, dry, and then extrude it into shape. The existing drying equipment mainly includes a draining screening device and a drying hot air device on the draining screening device. However, in actual use, in order to increase the output, the material bed of the draining screening device is thick, which makes it difficult to drain the water in the middle of the material layer. It is necessary to increase the drying time or increase the hot air power to improve the drying efficiency. The equipment has high energy consumption and the drying efficiency needs to be further improved. Utility Model Content

[0003] The purpose of this utility model is to provide a waste drip irrigation tape recycling and drying device to solve the technical problems of low drying efficiency and high energy consumption in existing waste drip irrigation tape drying devices.

[0005] Furthermore, a fixing ring is fixedly fitted on the outside of the heat insulation cylinder, and a load-bearing ring is provided below the fixing ring. The load-bearing ring is fixedly installed on the frame. Several mounting grooves are evenly distributed along the circumference on the load-bearing ring, and ball bearings are installed in the mounting grooves. A rolling ring groove matching the ball bearings is provided at the bottom of the fixing ring, and the ball bearings roll in contact with the rolling ring groove.

[0006] Furthermore, the rotary drive assembly includes a gear ring fixedly mounted on the heat insulation cylinder, the gear ring meshing with a gear shaft, the gear shaft being rotatably connected to the frame, and the gear shaft being drively connected to an electric motor.

[0007] Furthermore, several heat-conducting rods are evenly distributed along the circumference on the outer wall of the sieve basket, and the other end of the heat-conducting rods is connected to the inner wall of the vertical cylinder.

[0008] Furthermore, the heating wire is spiral-shaped.

[0009] Furthermore, the sieve basket is composed of several vertically arranged sieve bars, the extension lines of which do not intersect the axis of the sieve basket, and any two adjacent sieve bars form a sieve gap.

[0010] The beneficial effects of this utility model are as follows: This utility model designs a rotary drying device. First, the high-speed rotation of the vertical cylinder and the sieve basket removes most of the moisture from the crushed waste drip irrigation tape. The remaining small amount of moisture is dried by the heat generated by the heating wire during the falling and rotation process. The combination of spin drying and drying improves the drying efficiency of waste drip irrigation tape. The equipment has low energy consumption and is worthy of widespread promotion and use.

Detailed Implementation

[0016] like Figures 1 to 3 As shown, a waste drip irrigation tape recycling and drying device includes a vertically arranged vertical cylinder 2, a discharge hopper 9 installed below the vertical cylinder 2, a drain pipe 8 connected to the discharge hopper 9, a sieve basket 3 coaxially arranged inside the vertical cylinder 2, the vertical cylinder 2 and the sieve basket 3 forming a drainage annular cavity 7, an electric heating wire 5 installed on the outer wall of the vertical cylinder 2, and a heat insulation cylinder 4 fixedly fitted outside the vertical cylinder 2. The arrangement of the electric heating wire 5 and the heat insulation cylinder 4 can ensure that the waste drip irrigation tape does not directly contact the heat source and melt, and can also provide a high temperature. The electric heating wire 5 is located in the annular heat cavity formed by the vertical cylinder 2 and the heat insulation cylinder 4. The vertical cylinder 2 is connected to a rotary drive assembly and is connected to a frame 1 by rolling.

[0017] like Figure 3As shown, a fixing ring 13 is fixedly fitted on the outside of the heat insulation cylinder 4, and a load-bearing ring 15 is provided below the fixing ring 13. The load-bearing ring 15 is fixedly installed on the frame 1. Several mounting grooves are evenly distributed along the circumferential direction on the load-bearing ring 15. Ball bearings 14 are installed in the mounting grooves. A rolling ring groove 16 matching the ball bearings 14 is provided at the bottom of the fixing ring 13. The ball bearings 14 roll in contact with the rolling ring groove 16.

[0018] like Figure 1 As shown, the rotary drive assembly includes a gear ring 10 fixedly mounted on the heat insulation cylinder 4. The gear ring 10 meshes with a gear shaft 11, which is rotatably connected to the frame 1. The gear shaft 11 is connected to the motor 12 for transmission.

[0019] To improve thermal conductivity to a certain extent, such as Figure 2 and Figure 3 As shown, several heat-conducting rods 6 are evenly distributed along the circumference on the outer wall of the sieve basket 3. The other end of the heat-conducting rod 6 is connected to the inner wall of the vertical cylinder 2. The heating wire 5 is spiral-shaped.

[0020] like Figure 4 As shown, in order to prevent the screen holes from clogging, the screen basket 3 is composed of several vertically arranged screen bars 17. The extension lines of the screen bars 17 do not intersect with the axis of the screen basket 3. Any two adjacent screen bars 17 form a screen gap 18, and the screen gap 18 is arranged in a vortex in the circumferential direction.

[0021] In specific work, such as Figures 1 to 4 As shown, the wet waste drip irrigation tape is fed tangentially from the top of the screen basket 3. The motor 12 is started, and the gear shaft 11 drives the gear ring 10, together with the vertical cylinder 2, screen basket 3, and heat insulation cylinder 4, to rotate at high speed, thereby shaking off the water on the waste drip irrigation tape. The water that is shaken off enters the drainage ring cavity 7 and is finally discharged through the drainage pipe 8. During this process, the heat generated by the heating wire 5 causes the temperature inside the screen basket 3 to rise, and the high-speed rotation of the waste drip irrigation tape generates hot air, which evaporates the small amount of water on the waste drip irrigation tape.

[0022] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
