Description

Technical Field

[0001] The present invention belongs to the field of rubber compound processing equipment, and particularly relates to a rubber compound recycling device. Background Art

[0002] Rubber compound recycling refers to the process of collecting, processing, and reusing waste rubber, plastic, silicone, and other materials, aiming to reduce resource waste, reduce environmental pollution, and promote the development of circular economy;

[0003] During the rubber compound recycling process, recycling equipment is generally used; the provided recycling equipment is mostly used to heat and melt the waste rubber compound after crushing and grinding it into a liquid rubber for recycling; the recycling equipment provided in the related technology mostly has this structural form: including a crushing box and a heating box connected to the lower end of the crushing box. Two crushing rollers are symmetrically distributed and installed inside the crushing box, and a crushing gap is formed between the two crushing rollers; a spherical melting furnace is formed inside the heating box, and a large heating pipe, two medium heating pipes, and two small heating pipes are installed inside the spherical melting furnace;

[0004] When using this recycling equipment for recycling rubber compounds, after putting the waste materials into the crushing box, the two crushing rollers symmetrically distributed and installed inside the crushing box move relative to each other to perform extrusion and shearing crushing operations on the rubber compound passing through the gap between the crushing rollers. The crushed rubber compound falls into the spherical melting furnace, and the heating pipes provided are used to perform melting operations on the crushed rubber compound;

[0005] The structure of this recycling equipment is reasonably designed. The crushing box can perform basic crushing operations on the rubber compound. When the crushed rubber compound passes through the spherical melting furnace, the large heating pipe, two medium heating pipes, and two small heating pipes arranged inside the spherical melting furnace uniformly and quickly heat the spherical melting furnace. Moreover, using this spherical comprehensive heating method can quickly melt the rubber compound into a rubber liquid, with a short heating time for the rubber compound and a good melting effect for the rubber compound;

[0006] However, this recycling equipment also has some defects. For example, since the crushing rollers arranged inside the crushing box only perform one-time crushing processing on the incoming rubber compound, the particle size of the rubber compound after crushing is relatively large in the later stage; when heating and melting in the heating box in the later stage, a large heating pipe, two medium heating pipes, and two small heating pipes are arranged inside the spherical heating box to uniformly and quickly heat the spherical melting furnace. Moreover, in order to reduce the heating time and improve the heating and melting efficiency, the crushed rubber particles are required to reach a certain fineness (generally the particle size reaches 3 - 5 mm); obviously, the arrangement of so many heating pipes and the raw material properties of the relatively large particle size of the crushed rubber compound require sacrificing more energy consumption to achieve;

[0007] Aiming at the problems in the above background art, the present invention aims to provide a rubber compound recycling device. Summary of the Invention

The cylinder is installed on the cylinder frame, and a telescopic rotating shaft is provided at the output end of the cylinder. The telescopic rotating shaft is connected to the central positions of the multiple turntables distributed up and down inside the crushing box.

[0015] As a further solution of the present invention: The output component includes a servo motor, a driving wheel, and a driven wheel. The servo motor is installed and fixed on one side of the top seat through a fixing frame, and a driving wheel is provided at the output end of the servo motor; the driven wheel is rotatably installed on the top seat, and a meshing disc is provided on the driven wheel.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] Compared with the current rubber material recycling device, the rubber material recycling device described herein has the following advantages:

[0019] It changes the original method of crushing and grinding the rubber material by setting crushing rollers inside the crushing box and melting the crushed rubber material by installing multiple heating tubes inside the heating box;

[0020] Instead, a crushing assembly is provided inside the crushing box; a cylinder frame is provided on the top seat, and a lifting assembly is installed on the cylinder frame.

By installing multiple turntables inside the crushing box, multiple crushing operations on the rubber material entering the inside of the crushing box can be realized, which is used to improve the granularity of the crushed rubber material; moreover, the lifting assembly provided can adjust the processing depth position of the crushing assembly inside the crushing box according to processing requirements;

[0021] In addition, the heating box provided uses microwave to heat the rubber material, which has multiple advantages: one is energy saving. First of all, the high temperature generated by the self-induction of the heated object under the excitation of microwave can greatly shorten the desulfurization time. For example, it only takes 20 minutes for EPDM waste rubber, thus saving the energy required for desulfurization; moreover, since the rubber material has been processed into raw materials with a smaller granularity inside the crushing box, the microwave operation of the heating box is more material-saving.

[0031] Please refer to Figure 1-2 , the present invention provides a technical solution: a rubber material recycling device, and the rubber material recycling device includes:

[0032] The top seat 5, the bracket 13 and the base 14, the top seat 5 and the base 14 are respectively located at the upper and lower ends of the bracket 13, and the provided base 14 is used to stably support the entire rubber material recycling device;

[0033] Among them, a crushing box 12 is installed on a part of one side of the bracket 13 between the top seat 5 and the base 14, and a crushing component is arranged inside the crushing box 12; a cylinder frame 7 is arranged on the top seat 5, and a lifting component is installed on the cylinder frame 7. The output end of the lifting component installed on the cylinder frame 7 is connected to the crushing component arranged inside the crushing box 12. The operation of the lifting component outputs kinetic energy to adjust the processing depth position of the crushing component inside the crushing box 12; at the same time, an output component is installed on the top seat 5, and the output component installed on the top seat 5 is connected to the output end of the lifting component. When the output component outputs kinetic energy, it can drive the crushing component inside the crushing box 12 to rotate at a high speed, so as to realize the crushing operation on the rubber material entering the inside of the crushing box 12;

[0034] In addition, a feed inlet 11 is opened at the upper end of the crushing box 12, and the feed inlet 11 opened at the upper end of the crushing box 12 is used for feeding; a heating box 15 is installed inside the base 14, and the discharge port position of the crushing box 12 is connected to the feed inlet position of the heating box 15; the provided heating box 15 is used for microwave heating and melting of the crushed rubber powder;

[0035] In the embodiment of the present invention, when using the rubber material recycling device, the recycled rubber material to be processed is fed into the inside of the crushing box 12 through the feed inlet 11; after the recycled rubber material enters the inside of the crushing box 12, the output component is started, and the output kinetic energy of the output component can drive the crushing component inside the crushing box 12 to rotate at a high speed, so as to grind and crush the recycled rubber material entering the inside of the crushing box 12;

[0036] During the process of the crushing component operating to crush and grind the rubber material, according to the processing requirements, the lifting component can be started to adjust the processing depth position of the crushing component inside the crushing box 12;

[0037] In addition, after the rubber material is crushed and processed, it enters the heating box 15, and the provided heating box 15 is used for microwave melting operation on the entered crushed rubber material;

[0038] Please refer to Figure 2, in an embodiment of the present invention, the crushing assembly includes a turntable 17 and crushing teeth 16. The turntables 17 are arranged vertically inside the crushing box 12, and the axial positions of the multiple vertically arranged turntables 17 are connected to the output end of the lifting assembly; a reinforcing tooth 19 and a concave tooth 18 are annularly distributed and installed on the outer side of the turntable 17. The concave tooth 18 and the reinforcing tooth 19 are fixedly connected. The outer side of the concave tooth 18 protrudes, and a groove is formed inside the concave tooth 18; at the same time, the crushing teeth 16 are annularly distributed and installed on the inner wall of the crushing box 12;

[0039] In an embodiment of the present invention, when the crushing assembly is used to crush the rubber material entering the inside of the crushing box 12, after the output assembly outputs kinetic energy, it can drive the turntables 17 arranged vertically inside the crushing box 12 to rotate at high speed. When the turntables 17 rotate at high speed, it will drive the concave teeth 18 and the reinforcing teeth 19 distributed on the outer side of the turntable 17 to rotate simultaneously. Through the cooperative action of the high-speed rotating concave teeth 18, the reinforcing teeth 19 and the crushing teeth 16 fixedly installed on the inner wall of the crushing box 12, the rubber material entering the inside of the crushing box 12 can be subjected to extrusion, shearing, and grinding operations. By installing multiple turntables 17 inside the crushing box 12, multiple crushing operations on the rubber material entering the inside of the crushing box 12 can be realized, which is used to improve the granularity of the crushed rubber material;

[0040] Please refer to Figure 1 and Figure 2 , in an embodiment of the present invention, the lifting assembly includes a cylinder 6 and a telescopic rotating shaft 10. The cylinder 6 is installed on the cylinder frame 7, and the output end of the cylinder 6 is provided with a telescopic rotating shaft 10. The telescopic rotating shaft 10 is connected to the axial positions of the multiple vertically arranged turntables 17 inside the crushing box 12;

[0041] When the cylinder 6 outputs kinetic energy, it can push the telescopic rotating shaft 10 to lift and lower. When the telescopic rotating shaft 10 lifts and lowers, it can adjust the processing depth position of the multiple turntables 17 installed on the telescopic rotating shaft 10 inside the crushing box 12, thereby changing the processing angle position of the entire crushing assembly;

[0042] Please refer to Figure 1 and Figure 2 , in an embodiment of the present invention, the output assembly includes a servo motor 1, a driving wheel 2, and a driven wheel 8. The servo motor 1 is fixedly installed on one side of the top seat 5 through a fixing frame 3 on one side, and the output end of the servo motor 1 is provided with a driving wheel 2; the driven wheel 8 is rotatably installed on the top seat 5, and a meshing disc 9 is provided on the driven wheel 8. The provided telescopic rotating shaft 10 passes through the meshing disc 9 and the driven wheel 8 at the same time, and the outer side of the telescopic rotating shaft 10 meshes with the outer side of the meshing disc 9; the outer sides of the driven wheel 8 installed on the top seat 5 and the driving wheel 2 are connected by a conveyor belt 4;

[0043] In an embodiment of the present invention, when the output component is activated to drive the telescopic rotating shaft 10 to rotate at a high speed, and then the crushing component installed at the lower end of the telescopic rotating shaft 10 operates at a high speed to perform a crushing operation on the rubber material entering the inside of the crushing box 12, the servo motor 1 is activated. The servo motor 1 outputs kinetic energy to drive the driving wheel 2 to rotate at a high speed. Since the outer side of the driving wheel 2 is connected to the outer side of the driven wheel 8 through the conveyor belt 4, and the driven wheel 8 is provided with an engaging disc 9, and the telescopic rotating shaft 10 is engaged and installed at the axial center position of the engaging disc 9; therefore, when the driving wheel 2 rotates, it will drive the driven wheel 8 to rotate, and when the driven wheel 8 rotates, it will drive the telescopic rotating shaft 10 installed at the axial center position of the engaging disc 9 to rotate, thereby enabling the crushing component provided on the telescopic rotating shaft 10 to rotate at a high speed to perform a shearing and crushing operation on the rubber material entering the inside of the crushing box 12;

[0044] Please refer to Figure 1 and Figure 3 , in an embodiment of the present invention, a heating cavity 21 is formed inside the heating box 15, a blanking inclined plate 22 is installed inside the heating cavity 21, and convex teeth 23 are distributed and installed on the surface of the blanking inclined plate 22; at the same time, microwave generators 20 are symmetrically distributed and installed at the positions where the crushing box 12 is connected to the heating box 15 inside the heating cavity 21;

[0045] In an embodiment of the present invention, when the crushed rubber material falls on the upper surface of the blanking inclined plate 22, after the power supply of the microwave generator 20 is turned on, the microwave generator 20 generates microwaves, and the microwaves diffuse into the heating box 15; since the rubber material molecules are subjected to rapid vibrations in the microwave field, at this time, the sulfur bridges between the waste rubber molecules are dipoles. When they are subjected to 2.45 billion oscillations per second, they will change directions instantaneously due to inertia and emit huge energy, which is converted into the heat required for melting the rubber material;

[0046] By using the method of heating the rubber material with microwaves, there are multiple advantages: one is energy saving. First of all, the high temperature generated by the self-induction of the heated object under the excitation of microwaves can greatly shorten the desulfurization time. For example, it only takes 20 minutes for EPDM waste rubber, thus saving the energy required for desulfurization; in addition, since it is not necessary to pre-crush the waste rubber to a certain fineness (for example, 30 mesh), generally, a particle size of 3 - 5 mm is sufficient, so the energy consumption required for the previous process (crushing) is also greatly reduced; the second is less pollution. There is no need to use raw materials that produce pollutants such as softeners and reactivation agents; in addition, since no boiler is used, there is no emission of soot and greenhouse gases;

[0047] The working principle and usage process of the present invention:

[0048] The recycled rubber material to be processed is fed into the inside of the crushing box 12 through the feeding port 11; after the recycled rubber material enters the inside of the crushing box 12, the output component is started, and the kinetic energy output by the output component can drive the crushing component inside the crushing box 12 to rotate at a high speed, which is used to grind and crush the recycled rubber material entering the inside of the crushing box 12;

[0049] After the rubber material is crushed and processed, it enters the inside of the heating box 15. The provided heating box 15 is used to perform microwave melting operation on the crushed rubber material entering it;

[0050] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
