Description

Technical Field

[0001] The present invention relates to the technical field of rubber production, and more specifically, the present invention relates to a granulating system for desulfurizing recycled rubber. Background Art

[0002] With the rapid development of the rubber industry, the problem of recycling and reusing waste rubber has become increasingly prominent. Recycling waste rubber can not only reduce environmental pollution but also save resources and achieve sustainable development. In the process of recycling waste rubber, desulfurization is an important step. Through desulfurization treatment, the elasticity of waste rubber can be restored, and its reuse value can be improved. However, after desulfurization, the waste rubber needs to be sheared in the subsequent production process to meet different production requirements.

[0003] Among them, the patent with publication number CN222451034U discloses a shearing device for use in the production after desulfurization of waste rubber, which is applied in the field of rubber production. It includes a housing, an inlet is provided on the housing, and a circulating mechanism and a shearing mechanism are provided inside the housing; When this structure is in use, by setting the housing, the inlet, the circulating mechanism and the shearing mechanism, during use, first, the waste rubber can be conveyed into the interior of the housing through the inlet, and then sheared by the shearing mechanism. At this time, the waste rubber that is not sheared in place is lifted upward by the circulating mechanism, so that the waste rubber that is not sheared in place is sheared again by the shearing mechanism until all the waste rubber is sheared in place. However, when this structure is in use, the materials sheared are discharged through through-holes, which causes the through-holes to be blocked by particles that cannot be discharged, resulting in the materials being easily piled up together, affecting the granulation efficiency and effect. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a granulating system for desulfurizing recycled rubber, aiming to solve the problems raised in the above background art.

[0005] The present invention provides the following technical solutions: A granulating system for desulfurizing recycled rubber includes two cylinders, and granulating components are arranged in the middle of both cylinders; The granulating component includes a lining cylinder arranged in the middle of the cylinder, and a plurality of discharge holes for discharging materials are formed through the upper part of the lining cylinder; A plurality of reinforcing support plates are distributed on the inner wall of the lining cylinder, and a plurality of connecting blocks are installed on one side of each reinforcing support plate through bolts, and extension plates are installed on each connecting block through bolts. One ends of a plurality of extension plates are fixedly provided with reinforcing arc blades, and a plurality of slitting grooves are formed at one ends of each reinforcing arc blade; An electric heating cylinder is provided in the middle of the inner lining cylinder. A plurality of partition plates are sleeved outside the electric heating cylinder, and each partition plate is provided with a carding hole. A plurality of slitting grooves are arranged side by side, and a slitting cavity is formed between two adjacent slitting grooves. The outside of the electric heating cylinder extends into the slitting cavity. The plurality of partition plates are all installed on the electric heating cylinder by bolts, and the diameters of the carding holes of the partition plates are arranged side by side from large to small; It can be seen that in the above technical solution, when the inner lining cylinder rotates continuously, the broken rubber can be blocked by the partition plate and then screened through the carding hole and conveyed to one side of another partition plate, so that the rubber that cannot pass through the carding hole can continuously pass through the strengthening arc blade and the slitting groove for slitting and crushing, so as to realize that rubber particles of different sizes can be slit into the same size and discharged through the discharge hole. At the same time, during the crushing process of the rubber, a desulfurizing agent solution is sprayed between the inner lining cylinder and the electric heating cylinder, and then heated by the electric heating cylinder. The rubber particles are mixed with the desulfurizing agent solution and heated to react for desulfurization. And the cylinder body and the inner lining cylinder can be tilted, so that the rubber that is easily broken into particles can automatically roll towards the lowest point, which is conducive to the discharge of rubber particles; Optionally, in a possible implementation manner, a plurality of limiting blocks are installed on the outside of the inner lining cylinder by bolts, and each limiting block is on the same plane. A toothed ring is installed on the plurality of limiting blocks by bolts. Two cylinder bodies are arranged opposite to each other, and an installation cavity is formed directly between the two cylinder bodies. The toothed ring is located in the installation cavity, and the toothed ring is rotatably connected to the cylinder body. One end of the cylinder body facing the toothed ring is provided with a motor. The motor is installed on the outside of the cylinder body by bolts. The output end of the motor is provided with a limiting block. The limiting block is located outside the toothed ring, and the limiting block meshes with the toothed ring. A gear is formed between the toothed ring and the inner lining cylinder. The bottoms of the two cylinder bodies are both installed with support legs by bolts, and the lengths of the two support legs are different; It can be seen that in the above technical solution, the limiting block is driven by the motor to rotate, and the limiting block meshes with the toothed ring, so that the toothed ring can drive the limiting block to rotate. The limiting block is installed on the inner lining cylinder by bolts, so that the inner lining cylinder can rotate along the axial direction of the cylinder body. When the inner lining cylinder rotates, it can drive a plurality of strengthening support plates to rotate. The strengthening arc blade crushes the rubber, and at the same time the slitting groove can slit the rubber, so that the rubber can be crushed.

[0006] The technical effects and advantages of the present invention: 1. In the present invention, the inner lining cylinder can rotate along the axial direction of the cylinder body. When the inner lining cylinder rotates, it can drive a plurality of strengthening support plates to rotate. The strengthening arc blade crushes the rubber, and at the same time the slitting groove can slit the rubber, so that the rubber can be crushed into particles; 2. When the inner lining cylinder rotates continuously in the present invention, the broken rubber can be blocked by the partition plate, screened through the carding holes and then conveyed to one side of another partition plate, so that the rubber that cannot pass through the carding holes can continuously be cut and broken by the strengthening arc blades and the slitting grooves, avoiding the accumulation of rubber particles of different sizes and improving the granulation efficiency. 3. In the present invention, each partition plate is arranged side by side from large to small through the carding holes, so that rubber particles of different sizes can be cut into uniform sizes and discharged through the discharge holes. Heated by the electric heating cylinder, it is easy for the rubber particles to be heated and react with the desulfurizing agent solution for desulfurization. Moreover, the cylinder body and the inner lining cylinder are inclined, so that the broken and granulated rubber can automatically roll towards the lowest point, facilitating the discharge of the rubber particles. In summary, through the corresponding cooperation of each structure, the broken rubber can be blocked by the partition plate, screened through the carding holes and then conveyed to one side of another partition plate, so that the rubber that cannot pass through the carding holes can continuously be cut and broken by the strengthening arc blades and the slitting grooves, avoiding the accumulation of rubber particles of different sizes and improving the granulation efficiency. Heated by the electric heating cylinder, it is easy for the rubber particles to be heated and react with the desulfurizing agent solution for desulfurization. Moreover, the cylinder body and the inner lining cylinder are inclined, so that the broken and granulated rubber can automatically roll towards the lowest point, facilitating the discharge of the rubber particles.

[0015] As shown in the attached Figures 1 - 5 In a granulation system for regenerated rubber desulfurization shown in the figure, through the granulation components provided on the cylinder body 1, through the corresponding cooperation of each structure, the broken rubber can be blocked by the partition board 11 and then screened through the combing holes 12 and transported to one side of another partition board 11, so that the rubber that cannot pass through the combing holes 12 can continue to be slit and broken through the strengthening arc blades 7 and the slitting cutter grooves 8, avoiding the accumulation of rubber particles of different sizes and improving the granulation efficiency. Through the heating of the electric heating cylinder 10, it is easy for the rubber particles to be heated and react after being mixed with the desulfurizing agent solution for desulfurization. And the cylinder body 1 and the inner lining cylinder 2 are inclined, so that the rubber broken into particles can automatically roll towards the lowest point, which is easy for the rubber particles to be discharged. And the specific structure of the components is as follows; The granulation components include an inner lining cylinder 2 arranged in the middle of the cylinder body 1, and a plurality of discharge holes 3 for discharging materials are penetrated and opened on the upper part of the inner lining cylinder 2; A plurality of strengthening support plates 4 are distributed on the inner wall of the inner lining cylinder 2, and a plurality of connecting blocks 5 are installed on one side of each strengthening support plate 4 through bolts, and a plurality of extension plates 6 are installed on each connecting block 5 through bolts. One ends of the plurality of extension plates 6 are fixedly provided with strengthening arc blades 7, and a plurality of slitting cutter grooves 8 are opened at one ends of each strengthening arc blade 7; An electric heating cylinder 10 is arranged in the middle of the inner lining cylinder 2. A plurality of partition boards 11 are sleeved outside the electric heating cylinder 10, and a plurality of combing holes 12 are provided on each partition board 11. The plurality of slitting cutter grooves 8 are arranged side by side, and a slitting cavity 9 is formed between two adjacent slitting cutter grooves 8. The outside of the electric heating cylinder 10 extends into the slitting cavity 9. The plurality of partition boards 11 are all installed on the electric heating cylinder 10 through bolts, and the diameters of the combing holes 12 of each partition board 11 are arranged side by side from large to small; A number of limit blocks 13 are installed on the outer side of the inner lining cylinder 2 by bolts, and all the limit blocks 13 are on the same plane. Tooth rings 14 are installed on the multiple limit blocks 13 by bolts. Two cylinders 1 are arranged oppositely, and an installation cavity 15 is formed directly between the two cylinders 1. The tooth rings 14 are located in the installation cavity 15, and the tooth rings 14 are rotatably connected to the cylinders 1. One end of the cylinder 1 facing the tooth ring 14 is provided with a motor 17. The motor 17 is installed on the outer side of the cylinder 1 by bolts. The output end of the motor 17 is provided with a limit block 13. The limit block 13 is located outside the tooth ring 14, and the limit block 13 meshes with the tooth ring 14. A gear 18 is formed between the tooth ring 14 and the inner lining cylinder 2. Support legs 16 are installed at the bottoms of the two cylinders 1 by bolts, and the lengths of the two support legs 16 are different.

[0016] The specific working principle is as follows. When granulating the recycled rubber, the rubber is placed between the inner lining cylinder 2 and the electric heating cylinder 10. The motor 17 drives the limit block 13 to rotate. The limit block 13 meshes with the tooth ring 14, and then the tooth ring 14 can drive the limit block 13 to rotate. The limit block 13 is installed on the inner lining cylinder 2 by bolts, and then the inner lining cylinder 2 can rotate along the axial direction of the cylinder 1. When the inner lining cylinder 2 rotates, it can drive multiple strengthening support plates 4 to rotate. The strengthening arc blades 7 crush the rubber, and at the same time, the slitting knife grooves 8 can slit the rubber, so that the rubber can be crushed. At the same time, when the inner lining cylinder 2 continues to rotate, the crushed rubber can be blocked by the partition plate 11 and then screened through the combing holes 12 and conveyed to one side of another partition plate 11, so that the rubber that cannot pass through the combing holes 12 can continue to be slit and crushed by the strengthening arc blades 7 and the slitting knife grooves 8. And each partition plate 11 is arranged side by side from large to small through the combing holes 12, so that rubber particles of different sizes can be slit into the same size and discharged through the discharge holes 3. At the same time, during the crushing process of the rubber, a desulfurizing agent solution is sprayed between the inner lining cylinder 2 and the electric heating cylinder 10, and then heated by the electric heating cylinder 10. The rubber particles are mixed with the desulfurizing agent solution and heated to react for desulfurization. At the same time, the two cylinders 1 are supported by the support legs 16 with different lengths, so that the cylinders 1 and the inner lining cylinder 2 can be inclined, and the rubber that is easy to be crushed into particles can automatically roll towards the lowest point, which is convenient for the rubber particles to be discharged.

[0017] Different from the prior art, the present application discloses a granulation system for desulfurizing recycled rubber. Through the corresponding cooperation of each structure, the crushed rubber can be blocked by the partition plate 11 and then transported to one side of another partition plate 11 after being screened through the combing holes 12, so that the rubber that cannot pass through the combing holes 12 can continue to be cut and crushed by the reinforcing arc blades 7 and the slitting grooves 8, avoiding the accumulation of rubber particles of different sizes and improving the granulation efficiency. Through the heating of the electric heating cylinder 10, it is easy for the rubber particles to be heated and react after being mixed with the desulfurizing agent solution for desulfurization. Moreover, the cylinder body 1 and the inner lining cylinder 2 are inclined, so that the rubber crushed into particles can automatically roll towards the lowest point, facilitating the discharge of the rubber particles.

[0018] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
