Description

Technical Field

[0001] The invention belongs to the technical field of waste tire recycling, and more specifically, particularly relates to a recycling and processing device for waste rubber tires. Background Art

[0002] Waste rubber tires refer to tires that have reached the end of their service life and are no longer suitable for use in vehicles. Since rubber materials are highly stable and difficult to degrade naturally, waste tires will cause serious environmental pollution if not properly handled, occupying a large amount of land resources, becoming one of the environmental problems that need to be solved urgently. Therefore, the recycling and reuse of waste tires is particularly important.

[0003] However, the existing waste rubber tire recycling equipment still has the following shortcomings when used:

[0004] 1. Most of the existing waste rubber tires will have residual impurities (such as dirt, grease, metal fragments, etc.). The existing equipment has a poor cleaning effect on the impurities in the waste rubber tires during processing, which can easily affect the purity and quality of the product, resulting in a decrease in product performance, such as weakened strength and reduced durability. In addition, if the equipment is not thoroughly cleaned, it may damage the processing equipment during the processing, increasing maintenance costs and downtime;

[0005] 2. The cutting blades in the existing waste rubber tire recycling equipment are mostly non-adjustable, which makes it difficult to optimize the cutting for tires of different hardness and thickness, resulting in slow cutting speed and reduced efficiency. The fixed cutting angle and force can easily cause the blades to wear prematurely, requiring more frequent replacement, which increases maintenance costs.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] In the present invention, the inner groove, the wedge-shaped support rod, the vertical bar, the second spring, the positioning rod and the extrusion plate are provided. When the extrusion plate moves, the three wedge-shaped support rods are squeezed. At this time, the three wedge-shaped support rods are forced to slide outward inside the three inner grooves. At the same time, the three wedge-shaped support rods will also drive the three vertical bars to slide outward, and the three second springs will be compressed. At this time, the three wedge-shaped support rods will drive the three positioning rods to move outward. The three positioning rods will support and fix the waste rubber tire from the inside to the outside, and it is not easy to be misplaced during recycling and cleaning, which can reduce unnecessary wear of the tire during the processing process, ensure that more rubber materials can be recycled, reduce material losses, and improve resource recovery rate.

[0022] In the present invention, a nozzle, a scraper, a first driving motor, a rotating column, a top ring and a fixed cylinder are provided. Under the action of the first driving motor, the rotating column is driven to rotate, and the rotation of the rotating column drives the top ring and the fixed cylinder to rotate, and the rotation of the fixed cylinder drives the waste rubber tire to rotate at a uniform speed. Combined with the action of the high-pressure water flow of the nozzle, the surface of the waste rubber tire can be fully cleaned without dead angles. During the cleaning, the waste rubber tire can contact with the two scrapers, and then the two scrapers will remove the stubborn impurities on the surface of the waste rubber tire, so as to prepare for the subsequent processing process (such as cutting, crushing, thermal cracking, etc.), reduce equipment wear and blockage, extend the life of the equipment, and at the same time improve the quality of waste rubber tire recycling.

[0023] In the present invention, a suction pump is provided. When the waste rubber tire is cleaned, the suction pump can be turned off. At this time, the suction pump will no longer spray the water-based degradable reagent, and the waste rubber tire is still rotating with the equipment. At this time, centrifugal force will be generated under the rotation, and the water-based degradable reagent on the waste rubber tire can be thrown off. By drying the waste rubber tire, the residual moisture on the surface and inside of the tire can be quickly removed, the drying time is shortened, the entire recycling process is accelerated, and the production efficiency is improved;

[0024] In the present invention, a rotating column, a cutting strip, a threaded ring, an inner groove and a wedge-shaped support rod are provided, and the wedge-shaped support rod is retracted into the inner groove by the second spring restoring deformation. At this time, the waste rubber tire will no longer have support, and will fall and contact the cutting strip. At this time, multiple groups of cutting strips will efficiently crush the waste rubber tire. During crushing, four groups of threaded rings can be rotated on the rotating column, and the positions of the four groups of cutting strips can be adjusted by the four groups of threaded rings. By designing the four groups of cutting strips as a structure with adjustable spacing, the crushing effect can be adjusted according to different types of tires (such as car tires and truck tires), thereby improving the crushing efficiency and the quality of rubber powder.

[0025] In the present invention, by providing a recovery barrel, a mounting groove, a receiving tray and a mounting block, when the waste rubber tire is cleaned, impurities will be mixed with water-based degradable reagents and fall into the receiving tray, and can be collected by the receiving tray at this time. At this time, the impurities will be filtered and remain in the receiving tray, and when the cleaning is completed, the receiving tray can be rotated inside the recovery barrel, and the receiving tray will drive the two mounting blocks to slide out of the mounting groove, so as to facilitate the dumping of impurities, and then the receiving tray can be installed back to collect the fragments after the waste rubber tire is crushed, so that the equipment is convenient for collecting raw materials and impurities when in use, and is convenient for loading and unloading.

Since the nozzle 25 and the waste rubber tire are on the same horizontal line, the nozzle 25 will spray the water-based degradable reagent on the waste rubber tire. At this time, the first driving motor 32 can be started, and the rotating column 33 will be driven to rotate accordingly under the action of the first driving motor 32. The rotation of the rotating column 33 will drive the top ring 38 and the fixed cylinder 41 to rotate accordingly, and the rotation of the fixed cylinder 41 will drive the waste rubber tire to rotate at a uniform speed.

During crushing, the four sets of threaded rings 37 can be rotated on the rotating column 33, and the positions of the four sets of cutting strips 36 can be adjusted by the four sets of threaded rings 37. By designing the four sets of cutting strips 36 as a structure with adjustable spacing, the crushing effect can be adjusted according to different types of tires (such as car tires, truck tires), thereby improving the crushing efficiency and the quality of rubber powder;

[0041] The upper ends of the three wedge-shaped support rods 44 are fixedly installed with positioning rods 47, the upper end of the fixed cylinder 41 is evenly and equidistantly fixed with guide blocks 48 for positioning, the upper end of the fixed cylinder 41 is fixedly installed with a vertical rod 51, the upper end of the vertical rod 51 is fixedly installed with a second drive motor 52, the output shaft of the second drive motor 52 is fixedly installed with a first gear 53, the internal thread of the inner column 42 is installed with a screw rod 54, the upper end of the screw rod 54 is fixedly installed with a second gear 55, the second gear 55 is meshed with the first gear 53, and the lower end of the screw rod 54 is fixedly installed with an extrusion plate 56. When in use, the waste rubber tire can be placed on the three wedge-shaped support rods 44 first, at this time, the three wedge-shaped support rods 44 will support the tire, and then the second drive motor 52 can be started, and the first gear 53 will be driven to rotate under the action of the second drive motor 52, and the second gear 55 meshed with it will be driven to rotate under the rotation of the first gear 53. , and the rotation of the second gear 55 will drive the screw 54 to rotate inside the inner column 42. Since the two are threadedly connected, the screw 54 will move downward under the rotation. At this time, the screw 54 will also synchronously drive the extrusion plate 56 to move downward inside the fixed cylinder 41. Under the movement of the extrusion plate 56, the three wedge-shaped support rods 44 will be squeezed. At this time, the three wedge-shaped support rods 44 will be forced to slide outward inside the three inner grooves 43. At the same time, the three wedge-shaped support rods 44 will also drive the three vertical bars 45 to slide outward, and the three second springs 46 will be compressed. At this time, the three wedge-shaped support rods 44 will drive the three positioning rods 47 to move outward.

[0042] Working principle:

[0043] In the first step, when using, the waste rubber tire can be placed on the three wedge-shaped support rods 44. At this time, the three wedge-shaped support rods 44 will support the tire, and then the second drive motor 52 can be started. Under the action of the second drive motor 52, the first gear 53 will be driven to rotate, and the rotation of the first gear 53 will drive the second gear 55 meshing with it to rotate, and the rotation of the second gear 55 will drive the screw rod 54 to rotate inside the inner column 42. Since the two are threadedly connected, the screw rod 54 will move downward under the rotation, and at this time, the screw rod 54 will also synchronously drive the extrusion plate 56 to move downward inside the fixed cylinder 41 , the three wedge-shaped support rods 44 will be squeezed under the movement of the squeezing plate 56. At this time, the three wedge-shaped support rods 44 will be forced to slide outward inside the three inner grooves 43. At the same time, the three wedge-shaped support rods 44 will also drive the three vertical bars 45 to slide outward, and the three second springs 46 will be compressed accordingly. At this time, the three wedge-shaped support rods 44 will drive the three positioning rods 47 to move outward accordingly. The three positioning rods 47 will support and fix the waste rubber tire from the inside out, and it is not easy to be misplaced during recycling and cleaning, which can reduce unnecessary wear of the tire during the processing process, ensure that more rubber materials can be recycled, reduce material losses, and improve resource recovery rate;

[0044] In the second step, after the waste rubber tire is fixed, the suction pump 22 can be started. Under the action of the suction pump 22, the water-based degradable reagent in the liquid storage tank 14 will be extracted, and then sprayed out through the second connecting pipe 24 and the nozzle 25. Since the nozzle 25 and the waste rubber tire are on the same horizontal line, the nozzle 25 will spray the water-based degradable reagent on the waste rubber tire. At this time, the first driving motor 32 can be started. Under the action of the first driving motor 32, the rotating column 33 will be driven to rotate accordingly, and the rotation of the rotating column 33 will drive the top ring 38 and the fixing cylinder 41 rotates accordingly, and the rotation of the fixed cylinder 41 drives the waste rubber tire to rotate at a uniform speed, and the high-pressure water flow of the nozzle 25 can clean the surface of the waste rubber tire comprehensively without dead angles, and the waste rubber tire can contact the two scrapers 28 during cleaning, and then the two scrapers 28 will remove the stubborn impurities on the surface of the waste rubber tire, prepare for the subsequent processing process (such as cutting, crushing, thermal cracking, etc.), reduce equipment wear and blockage, extend equipment life, and also improve the quality of waste rubber tire recycling;

[0045] In the third step, when the waste rubber tire is cleaned, the suction pump 22 can be turned off. At this time, the suction pump 22 will no longer spray the water-based degradable reagent, and the waste rubber tire is still rotating with the equipment. At this time, centrifugal force will be generated under the rotation, and the water-based degradable reagent on the waste rubber tire can be thrown off. By drying the waste rubber tire, the residual moisture on the surface and inside of the tire can be quickly removed, the drying time is shortened, the entire recycling process is accelerated, and the production efficiency is improved;

[0046] In the fourth step, after the waste rubber tire is dried, the first step can be repeated, and the wedge-shaped support rod 44 can be retracted into the inner groove 43 by restoring the deformation of the second spring 46. At this time, the waste rubber tire will no longer have support, and will fall and contact the cutting strip 36. At this time, the multiple groups of cutting strips 36 will efficiently crush the waste rubber tire. During crushing, the four groups of threaded rings 37 can be rotated on the rotating column 33, and the positions of the four groups of cutting strips 36 can be adjusted by the four groups of threaded rings 37. By designing the four groups of cutting strips 36 as a structure with adjustable spacing, the crushing effect can be adjusted according to different types of tires (such as car tires and truck tires), thereby improving the crushing efficiency and the quality of rubber powder;

[0047] The fifth step is that when the waste rubber tire is cleaned, impurities will be mixed with water-based degradable reagents and fall into the receiving tray 16. At this time, they can be collected by the receiving tray 16. At this time, the impurities will be filtered and remain in the receiving tray 16. When the cleaning is completed, the receiving tray 16 can be rotated inside the recovery barrel 11. At this time, the receiving tray 16 will drive the two mounting blocks 17 to slide out of the mounting groove 15, so as to facilitate the dumping of impurities. Then the receiving tray 16 can be installed back to collect the fragments after the waste rubber tire is crushed, so that the equipment is convenient for collecting raw materials and impurities when in use, and is convenient for loading and unloading.
