Description

Technical Field

[0001] This utility model relates to the technical field of drip irrigation tape recycling and cleaning devices, specifically a waste drip irrigation tape cleaning and conveying line. Background Technology

[0002] Waste drip irrigation tape recycling requires first breaking it into small pieces, then washing to remove surface dirt, sand, and other impurities to ensure the purity of the recycled raw materials. Incomplete washing will severely affect the performance of the recycled plastics and reduce their recycling value. Current mainstream washing equipment centers on washing tanks, but generally lacks a pre-treatment mechanism for drip irrigation tape fragments. Dry mud clumps adhering to the surface of waste drip irrigation tape, even after breaking, remain stuck to the fragments. Directly introducing these fragments into the washing tank causes multiple problems: first, the dry mud clumps significantly increase the washing load, requiring more water, electricity, and time, leading to decreased efficiency and increased costs; second, the dry mud clumps become more sticky when wet, making them difficult to rinse and prone to secondary adhesion, further reducing the washing effect.

[0003] In summary, existing equipment lacks effective pretreatment and cannot remove dry mud clumps in advance, resulting in high cleaning load, long processing time, and low efficiency. Developing cleaning equipment with pretreatment capabilities has become a pressing technical challenge for the industry. Summary of the Invention

[0004] (a) Technical issues This utility model provides a waste drip irrigation tape cleaning and conveying line to solve the problem that the lack of a pre-treatment mechanism in existing cleaning equipment leads to increased cleaning load and reduced efficiency due to dry mud blocks.

[0005] (II) Technical Content To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a waste drip irrigation tape cleaning and conveying line, including a cleaning tank, a turning frame rotatably installed inside the cleaning tank, a motor for driving the turning frame to rotate fixed outside the cleaning tank, a pretreatment mechanism connected to the left side of the cleaning tank, the pretreatment mechanism including a screening box, two rotating rollers rotatably installed at the upper end inside the screening box, a number of evenly distributed hemispherical protrusions fixed on the rotating rollers, a second motor for driving the rotating rollers to rotate fixed outside the screening box, a vibrating screen plate mechanism installed at the bottom inside the screening box, the vibrating screen plate mechanism being inclined and having a discharge port connected to the cleaning tank at its lowest point, and a vertically arranged spiral discharge mechanism fixed inside the right side of the cleaning tank.

[0006] Furthermore, the vibrating screen plate mechanism includes an inclined screen plate installed inside the screening box, and a vibrating motor is fixedly installed at the bottom center of the inclined screen plate.

[0007] Furthermore, the spiral discharge mechanism includes a vertical conveying cylinder fixedly disposed on the bottom surface inside the cleaning tank. The vertical conveying cylinder is equipped with a spiral auger inside. The bottom of the vertical conveying cylinder has an inlet facing the left side of the cleaning tank, and the upper right side has a discharge outlet.

[0008] Furthermore, a guide plate is fixedly provided inside the cleaning tank and outside the feed inlet.

[0009] Furthermore, the bottom surface inside the cleaning tank is provided with a guide ramp running from left to right.

[0010] Furthermore, the guide plate is provided with water-permeable holes.

[0011] Furthermore, the washing tank is provided with a drain outlet on its side, and the screening box is provided with a slag discharge outlet at its bottom.

[0012] (III) Technical Effects Compared with existing technologies, the advantages of this invention are as follows: This conveyor line, through the installation of a pretreatment mechanism, utilizes hemispherical protrusions on the rotating rollers to crush and knead the broken drip irrigation tape fragments, initially removing surface dry mud lumps. Combined with the vibration screening of the inclined screen plate, the dry mud lumps are separated from the drip irrigation tape fragments and discharged through the slag outlet, preventing the dry mud lumps from directly entering the washing tank. This significantly reduces the water and electricity consumption and time required for the washing process, and substantially lowers the washing load. After the pretreatment to remove the dry mud lumps, the drip irrigation tape fragments enter the washing tank. There is no need to deal with sticky wet mud lumps; the material turning rack in the washing tank can fully agitate the fragments. Combined with the guiding action of the guide slope and guide plate, the fragments efficiently contact the washing water, reducing secondary adhesion of mud lumps, improving the thoroughness of the washing, and shortening the single washing time, thus improving the overall processing efficiency.

A pretreatment mechanism is connected to the left side of the cleaning tank 1. The pretreatment mechanism includes a screening box 4. Two rotating rollers 5 are rotatably installed at the upper end inside the screening box 4. Several evenly distributed hemispherical protrusions 6 are fixed on the rotating rollers 5. A motor 7 is fixedly installed outside the screening box 4 to drive the rotating rollers 5 to rotate. A vibrating screen plate mechanism is provided at the bottom inside the screening box 4. The vibrating screen plate mechanism is inclined and has a discharge port 8 connected to the cleaning tank 1 at its lowest point. A vertically arranged spiral discharge mechanism is fixedly installed on the right side inside the cleaning tank 1. A drain port 18 is provided on the side of the cleaning tank 1.

[0024] In this embodiment, as a preferred technical solution, the vibrating screen plate mechanism includes an inclined screen plate 9 installed inside the screening box 4, a vibrating motor 10 fixedly installed at the bottom center of the inclined screen plate 9, and a slag discharge port 19 provided at the bottom of the screening box 4.

[0025] In this embodiment, as a preferred technical solution, the spiral discharge mechanism includes a vertical conveying cylinder 11 fixedly disposed on the bottom surface inside the cleaning tank 1. A spiral auger 12 is provided inside the vertical conveying cylinder 11. The bottom of the vertical conveying cylinder 11 is provided with a feed inlet 13 facing the left side of the cleaning tank 1 and a discharge outlet 14 is provided on the right side of the upper end. A guide plate 15 is fixedly disposed inside the cleaning tank 1 and outside the feed inlet 13. A guide ramp 16 from left to right is provided on the bottom surface inside the cleaning tank 1. A water-permeable hole 17 is provided on the guide plate 15.

[0026] The workflow of this waste drip irrigation tape cleaning and conveying line is divided into three stages: pretreatment, cleaning, and discharge. The specific working principle is as follows: 1. Pre-treatment stage: After the waste drip irrigation tape to be treated is crushed in the early stage, the resulting drip irrigation tape fragments are transported to the screening box 4 of the pre-treatment mechanism; the second motor 7 is started, and the two motors 7 drive the two rotating rollers 5 at the upper end of the screening box 4 to rotate synchronously in opposite directions. The hemispherical protrusion 6 rotates with the rotating rollers 5, crushing and kneading the drip irrigation tape fragments entering the screening box 4, and initially peeling off the dry mud lumps attached to the surface of the fragments; the drip irrigation tape fragments and the separated dry mud lumps fall together to the vibrating screen plate mechanism at the bottom of the screening box 4; the vibrating motor 10 is started, driving the inclined screen plate 9 to vibrate at high frequency. Under the action of vibration, the drip irrigation tape fragments slide along the inclined surface of the inclined screen plate 9, and finally slide out from the discharge port 8 at the lowest point of the inclined screen plate 9, and enter the washing tank 1 connected to the discharge port 8; the dry mud lumps fall through the screen holes of the inclined screen plate 9 to the bottom of the screening box 4, and are finally discharged from the slag discharge port 19.

[0027] 2. Cleaning Stage: After the drip irrigation tape fragments enter the cleaning tank 1, an appropriate amount of cleaning water is injected into the cleaning tank 1. The motor 3 is started, and the motor 3 drives the tipping rack 2 inside the cleaning tank 1 to rotate. The direction of rotation of the tipping rack 2 is opposite to the direction of the drip irrigation tape fragments sliding down. During the rotation, the tipping rack 2 continuously stirs the drip irrigation tape fragments and cleaning water in the cleaning tank 1, so that the fragments are fully in contact with the cleaning water, and washes away the small amount of fine impurities remaining after pretreatment. The drip irrigation tape fragments gradually slide along the guide slope 16 to the feed port 13 of the spiral discharge mechanism. The wastewater generated during the cleaning process can be discharged regularly through the drain port 18 on the side of the cleaning tank 1 to ensure the cleanliness of the cleaning water.

[0028] 3. Discharge stage: The drip irrigation tape fragments enter the vertical conveying cylinder 11 through the inlet 13. The screw discharge mechanism is activated, causing the screw conveyor 12 inside the vertical conveying cylinder 11 to rotate at high speed. During the rotation, the screw conveyor 12 generates an upward conveying force, which conveys the drip irrigation tape fragments inside the vertical conveying cylinder 11 from the bottom of the vertical conveying cylinder 11 upward. Excess water flows downward, which plays the role of discharging and draining water at the same time. Finally, the material is discharged from the discharge port 14 on the upper right side of the vertical conveying cylinder 11 and discharged from the cleaning tank 1, completing the entire cleaning and conveying process.

[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
