Description

Technical Field

[0001] This utility model relates to the field of PVC corrugated pipe waste recycling technology, and in particular to a waste recycling device in PVC corrugated pipe production. Background Technology

[0002] The production process of PVC corrugated pipes generates a large amount of cutting waste and defective products. Recycling and reusing this waste is crucial for reducing costs and pollution. Existing recycling devices often use multiple motors to drive stirring and cooling modules separately, resulting in complex structures, high energy consumption, and increased equipment costs. Furthermore, traditional stirring mechanisms often involve a single rotary motion, making it difficult to heat the molten material evenly and prone to localized overheating and degradation. In addition, most devices are inadequate in handling the high-temperature gases containing harmful substances such as hydrogen chloride generated during melting, resulting in low cooling efficiency and inconvenient disassembly and assembly of filter components. This not only affects equipment lifespan but may also lead to non-compliance with environmental emission standards. There is a lack of integrated solutions that combine efficient stirring, synergistic cooling and filtration, and a streamlined structure.

[0003] A search revealed patent publication number CN219476401U, which discloses a PVC cable waste recycling device. The device includes a support frame, with a tank for melting and recycling PVC cable waste mounted inside. The design of the tank, lid, pipe, ring seat, ball, cross rod, and spring allows harmful gases generated during the melting of PVC cable waste to accumulate inside the tank. When the accumulated gases reach a certain level, they are automatically discharged. The high-temperature gases also provide some assistance during the melting process. The design of a water tank, branch pipes, loop pipes, bends, and an air purifier facilitates cooling and purification of the automatically discharged gases. This not only reduces the impact of high-temperature gas discharge but also effectively lowers the content of harmful substances in the gases, thereby reducing the hazards caused by gases during the melting of PVC cable waste and improving safety during the melting process.

[0004] While existing technologies can achieve a certain degree of recycling and reuse, they suffer from drawbacks such as the lack of a multi-functional collaborative driving mechanism and efficient stirring method. In view of this, we propose a waste recycling and reuse device for PVC corrugated pipe production, which solves the above problems. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a waste recycling and reuse device for PVC corrugated pipe production.

[0006] The technical solution of this utility model is as follows: A waste recycling and reuse device in the production of PVC corrugated pipes includes a tank, a sleeve, and a turntable. The sleeve is fixedly connected to the upper outer wall of the tank, and a first mounting frame is fixedly connected to the upper outer wall of the sleeve. A bidirectional rotating motor is fixedly connected inside the first mounting frame. One output shaft of the bidirectional rotating motor is fixedly connected to the rotation center of the turntable. A pressure rod is fixedly connected to one side of the outer wall of the turntable. The other output shaft of the bidirectional rotating motor passes through a second mounting frame and is fixedly connected to the rotation center of a fan. Driving a single rotating motor can simultaneously make the stirring rod and the fan work.

[0007] When using the waste recycling device in the production of PVC corrugated pipes as described in this solution, a bidirectional rotating motor is driven. The output shaft at one end drives a turntable, causing a pressure rod on the turntable to rotate. The pressure rod periodically presses down on a moving frame, causing a moving block to move downwards. According to the movement of the guide column in the vortex, the moving block moves downwards and rotates simultaneously. When the pressure rod moves away from the moving frame, the spring releases its elastic tension, causing the moving block to rotate and rise. This process is repeated, thereby achieving repeated up-and-down stirring of the stirring rod inside the tank. The output shaft at the other end of the bidirectional rotating motor simultaneously drives a fan to rotate, cooling the high-temperature gas in the exhaust pipe. The activated carbon filter at the upper end of the exhaust pipe can be quickly installed and disassembled due to the good deformation capability of the rubber strip, and it also has strong sealing performance.

[0008] Preferably, the upper outer wall of the tank is fixedly connected to the lower end of the spring, and the other end of the spring is fixedly connected to the lower outer wall of the moving block. Both the spring and the moving block are located inside the sleeve. A moving frame is fixedly connected to the upper outer wall of the moving block, and a guide post is fixedly connected to one side of the outer wall of the moving block. The outer wall of the sleeve is provided with a swirl groove, and the guide post is located in the swirl groove. The guide post moves in the swirl groove, so that the moving block rotates while moving up and down.

[0009] Preferably, the upper end of the tank is provided with an exhaust pipe, and a fixing frame is fixedly connected to the outer wall of the exhaust pipe. The upper end of the fixing frame is not closed, so that the airflow generated by the fan can be guided upward.

[0010] Preferably, a second mounting bracket is provided on one side of the outer wall of the fixed frame, and a fan is fixedly connected to one side of the outer wall of the second mounting bracket, so that the airflow generated by the fan directly acts on the outer wall of the exhaust pipe.

[0011] Preferably, the upper end of the exhaust pipe is provided with a groove, an activated carbon filter screen is provided in the groove, and a rubber strip is provided on the outer wall of the activated carbon filter screen. The rubber strip is fitted into the groove, and the activated carbon filter screen can effectively absorb harmful substances generated by the molten material.

[0012] Preferably, a rotating rod is fixedly connected to the lower outer wall of the moving block, and a plurality of stirring rods arranged in a circumferential array are provided on the lower outer wall of the rotating rod, so that the molten material is heated evenly.

[0013] Preferably, the lower end of the tank is provided with a liquid outlet pipe, and the outer wall of the tank is provided with two symmetrical supports. The lower outer wall of the supports is fixedly connected to the base, and the molten material is discharged through the liquid outlet pipe.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] I. This utility model achieves multi-functional integration of a single motor by synchronously driving the stirring mechanism and the fan cooling mechanism with a bidirectional rotating motor. This not only simplifies the overall structure and reduces equipment costs, but also reduces energy consumption. At the same time, the stirring rod can stir the molten material in the tank in all directions through the up-and-down reciprocating rotation of the moving block, which greatly improves the uniformity of material heating, avoids PVC degradation caused by local overheating, and ensures the quality of recycled raw materials.

[0016] Second, based on the first beneficial effect, the cooling and filtration system of the exhaust pipe in the device works in tandem. The fan, guided by the fixed frame, efficiently cools the exhaust pipe. Combined with the adsorption effect of the activated carbon filter, it can reduce the corrosiveness of high-temperature gas to the pipe and extend the service life of the equipment. It can also effectively remove harmful substances in the exhaust gas and meet environmental emission requirements. Moreover, the activated carbon filter, through the interlocking design of rubber strips and grooves, can be quickly disassembled and installed, which is convenient for daily maintenance and replacement, further improving the practicality and ease of operation of the device.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0029] Example 1

[0030] Please see Figures 1-5 As shown, this embodiment is a waste recycling and reuse device in the production of PVC corrugated pipes, including a tank 2, a sleeve 7 and a turntable 15. The sleeve 7 is fixedly connected to the upper outer wall of the tank 2, and a first mounting frame 22 is fixedly connected to the upper outer wall of the sleeve 7. A bidirectional rotating motor 1 is fixedly connected inside the first mounting frame 22. One output shaft of the bidirectional rotating motor 1 is fixedly connected to the rotation center of the turntable 15. A pressure rod 5 is fixedly connected to one side of the outer wall of the turntable 15. The other output shaft of the bidirectional rotating motor 1 passes through the second mounting frame 20 and is fixedly connected to the rotation center of the fan 19. In use, after the bidirectional rotating motor 1 is started, one output shaft drives the turntable 15 to rotate, so that the pressure rod 5 moves in a circle with the turntable 15. The other output shaft synchronously drives the fan 19 to rotate, realizing the synchronous operation of stirring and cooling.

[0031] Example 2

[0032] Please see Figures 1-5 As shown, this embodiment, based on embodiment 1, further includes: the upper outer wall of the tank 2 is fixedly connected to the lower end of the spring 11, and the other end of the spring 11 is fixedly connected to the lower outer wall of the moving block 23. The spring 11 and the moving block 23 are both located inside the sleeve 7. A moving frame 6 is fixedly connected to the upper outer wall of the moving block 23, and a guide post 9 is fixedly connected to one side of the outer wall of the moving block 23. The outer wall of the sleeve 7 is provided with a swirl groove 8, and the guide post 9 is located in the swirl groove 8. In use, when the pressure rod 5 rotates with the turntable 15 to contact the moving frame 6, it will press down the moving frame 6 and drive the moving block 23 to move downward. At this time, the spring 11 is compressed, and the guide post 9 moves downward along the trajectory of the swirl groove 8, causing the moving block 23 to rotate. When the pressure rod 5 rotates away from the moving frame 6, the spring 11 resets and pushes the moving block 23 to move upward. The guide post 9 moves in the opposite direction along the swirl groove 8, so that the moving block 23 continues to rotate while rising, thereby realizing the up-and-down reciprocating rotational motion of the moving block 23.

[0033] The upper end of the tank body 2 is provided with an exhaust pipe 10, and a fixed frame 21 is fixedly connected to the outer wall of the exhaust pipe 10. When in use, the gas generated by the melting of the material in the tank body 2 is discharged outward through the exhaust pipe 10. The fixed frame 21 guides the airflow generated by the fan 19, so that the airflow acts more concentrated on the upper outer wall of the exhaust pipe 10, improving heat dissipation efficiency and preventing gas deposition.

[0034] A second mounting bracket 20 is provided on one side of the outer wall of the fixed frame 21. A fan 19 is fixedly connected to one side of the outer wall of the second mounting bracket 20. When in use, the airflow generated by the rotation of the fan 19 flows along the outer wall of the exhaust pipe 10 under the guidance of the fixed frame 21. Through heat exchange, it carries away part of the heat of the high-temperature gas in the exhaust pipe 10, reduces the gas temperature, and then discharges the gas.

[0035] The upper end of the exhaust pipe 10 is provided with a groove 16, and an activated carbon filter 18 is provided in the groove 16. A rubber strip 17 is provided on the outer wall of the activated carbon filter 18. The rubber strip 17 fits into the groove 16. In use, the cooled gas is discharged through the activated carbon filter 18. The activated carbon adsorbs harmful substances in the gas. The rubber strip 17 fills the gap between the groove 16 and the activated carbon filter 18 by its own deformation, which not only ensures the sealing to prevent the leakage of unfiltered gas, but also facilitates quick disassembly and replacement of the activated carbon filter 18.

[0036] A rotating rod 12 is fixedly connected to the lower outer wall of the movable block 23. The lower outer wall of the rotating rod 12 is provided with multiple stirring rods 13 arranged in a circular array. During use, the up-and-down reciprocating rotation of the movable block 23 is transmitted to the stirring rods 13 through the rotating rod 12, so that the stirring rods 13 move up and down and rotate simultaneously in the tank 2, which fully stirs the molten PVC waste in the tank, ensuring that the material is heated evenly and avoiding local overheating or insufficient melting.

[0037] The tank body 2 is provided with a liquid outlet pipe 14 at the lower end. The outer wall of the tank body 2 is provided with two symmetrical supports 3. The lower outer wall of the supports 3 is fixedly connected to the base 4. During use, the material that has been fully melted and stirred can be discharged through the liquid outlet pipe 14 and enter the subsequent processing stage. The supports 3 and the base 4 work together to stably support the tank body 2, ensuring the overall stability of the device during operation and avoiding loosening or displacement of components due to vibration.

[0038] Instructions for use: When using this device, the bidirectional rotating motor 1 drives the output shaft of one end to drive the turntable 15, causing the pressure rod 5 on the turntable 15 to rotate. The pressure rod 5 periodically presses down on the moving frame 6, causing the moving block 23 to move downward. According to the movement of the guide column 9 in the vortex 8, the moving block 23 moves downward and rotates at the same time. When the pressure rod 5 moves away from the moving frame 6, the spring 11 releases its elastic tension, causing the moving block 23 to rotate and rise. This process is repeated, thereby realizing the repeated up and down stirring of the stirring rod 13 in the tank 2. The output shaft of the other end of the bidirectional rotating motor 1 simultaneously drives the fan 19 to rotate, cooling the high-temperature gas in the exhaust pipe 10. The activated carbon filter 18 at the upper end of the exhaust pipe 10 can be quickly installed and disassembled due to the good deformation ability of the rubber strip 17, and has strong sealing performance. Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
