Description

Technical Field

[0001] This utility model relates to the field of rubber recycling technology, specifically a rubber recycling and reuse crushing device. Background Technology

[0002] In the field of rubber recycling, especially in the recycling and processing of waste tires and industrial rubber waste, my country has been advocating, encouraging and supporting the reuse of waste rubber and the production of reclaimed rubber. In the production of rubber seals, a large amount of rubber waste is usually generated, and these rubber wastes usually need to be recycled and reused.

[0003] The shortcomings of current rubber recycling and reuse equipment include: single-stage crushing devices are difficult to handle both coarse and fine crushing, resulting in high energy consumption and low output; lack of grading and screening mechanisms leads to inconsistent particle sizes in the output, affecting subsequent recycling; and reliance on manual sorting and feeding results in low production efficiency. Utility Model Content

[0004] Technical problems to be solved In view of the shortcomings of the prior art, this utility model provides a rubber recycling and reuse crushing device to solve the problems mentioned in the background art.

[0005] Technical solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rubber recycling and reuse crushing device, including a crusher fixing bracket, a feeding device fixedly installed above the crusher fixing bracket, a discharge box fixedly installed at the lower end of the crusher fixing bracket, a collection box provided at the right end of the discharge box, a conveyor belt device provided at the right end of the collection box, the other end of the conveyor belt device connected to a desulfurization tank, the right end of the desulfurization tank connected to a recycling box via the conveyor belt device, a primary crushing mechanism provided inside the crusher fixing bracket, a secondary crushing mechanism provided below the primary crushing mechanism, a rotating shaft provided at the front and rear sections of the primary crushing mechanism, a motor provided at the front end of the rotating shaft, and a motor drive provided at the front end of the secondary crushing mechanism.

[0007] Preferably, the discharge box has a steep slope inside, and the feeding device has a feeding port at the top.

[0008] Preferably, a baffle is provided around the primary crushing mechanism and a baffle is provided around the secondary crushing mechanism.

[0009] Preferably, the primary crushing mechanism is provided with a baffle around its perimeter, the front surface of the crusher fixing bracket is provided with a fixing seat, and the motor is located inside the fixing seat.

[0010] Preferably, the lower end of the primary crushing mechanism is provided with a first through hole, and the lower end of the secondary crushing mechanism is provided with a second through hole, wherein the first through hole is larger than the second through hole.

[0011] Preferably, the blades used in the primary crushing mechanism are wide-bladed, and the blades used in the secondary crushing mechanism are narrow-bladed.

[0012] Compared with the prior art, this utility model provides a rubber recycling and reuse crushing device with the following advantages: The steep slope structure of this rubber recycling and reuse crushing device utilizes the principle of natural gravity sliding down, allowing the crushed rubber particles to slide quickly to the outlet, reducing the risk of material accumulation and blockage. The combination design of wide and narrow blades in the crushing mechanism, through division of labor and cooperation, takes into account both coarse crushing efficiency and fine crushing precision, while reducing energy consumption and maintenance costs. It is an ideal solution for rubber grading and crushing. The outer baffle of the crushing mechanism can effectively block scattered materials and limit the movement range of rubber fragments, allowing them to be repeatedly acted on by the blades in the crushing chamber, ensuring thorough crushing.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figure 1-3As shown, a rubber recycling and reuse crushing device includes a crusher fixed support 1, a feeding device 4 fixedly installed above the crusher fixed support 1, a discharge box 2 fixedly installed at the lower end of the crusher fixed support 1, a collection box 5 at the right end of the discharge box 2, a conveyor belt device 6 at the right end of the collection box 5, the other end of the conveyor belt device 6 is connected to a desulfurization tank 7, the right end of the desulfurization tank 7 is connected to a recycling box 8 through the conveyor belt device 6, a primary crushing mechanism 13 is provided inside the crusher fixed support 1, a secondary crushing mechanism 16 is provided below the primary crushing mechanism 13, a rotating shaft 12 is provided at the front and rear sections of the primary crushing mechanism 13, a motor 11 is provided at the front end of the rotating shaft 12, and the motor 11 is provided at the front end of the secondary crushing mechanism 16 for driving.

[0017] Furthermore, the discharge box 2 is equipped with a steep slope 10, and the feeding device 4 is equipped with a feeding port 9 at the top.

[0018] Through the above technical solutions, the steep slope 10 structure utilizes the principle of natural gravity sliding to allow the crushed rubber particles to slide quickly toward the outlet, reducing the risk of material accumulation and blockage. The high-level feed inlet 9 utilizes the material's own weight to fall, reducing the need for mechanical pushing during feeding.

[0019] Furthermore, a baffle 15 is provided around the primary crushing mechanism 13, and a baffle 15 is provided around the secondary crushing mechanism.

[0020] Through the above technical solution, the baffle 15 can effectively block scattered materials and limit the movement range of rubber fragments, so that they are repeatedly acted on by the blades in the crushing chamber to ensure thorough crushing.

[0021] Furthermore, the primary crushing mechanism 13 is surrounded by a baffle 15, and the front surface of the crusher fixing bracket 1 is provided with a fixing seat 3, with the motor 11 inside the fixing seat 3.

[0022] Through the above technical solution, the motor 11 is integrated into the fixed base 3, which can be disassembled as a whole for easy maintenance. The motor 11 is directly connected to the crusher fixed bracket 1 through the fixed base 3, forming a stable power transmission structure and reducing the risk of vibration and displacement during high-speed operation.

[0023] Furthermore, the lower end of the primary crushing mechanism 13 is provided with a first through hole 14, and the lower end of the secondary crushing mechanism 16 is provided with a second through hole 17, wherein the first through hole 14 is larger than the second through hole 17.

[0024] Through the above technical solution, the larger first through hole 14 allows larger rubber blocks to pass through, reducing the load on the primary crushing mechanism 13 and improving the coarse crushing efficiency. The smaller second through hole 17 ensures that the rubber particles are further refined to achieve the target particle size and meet the requirements for subsequent recycling.

[0025] Furthermore, the blades used in the primary crushing mechanism 13 are wide-bladed, while the blades used in the secondary crushing mechanism 16 are narrow-bladed.

[0026] Through the above technical solution, the narrow blade has a small contact area and higher unit pressure, which can more efficiently refine rubber particles to the target particle size. The narrow blade has less cutting resistance to pre-crushed rubber particles, reducing the load on the secondary crushing mechanism 16.

[0027] Working principle: First, the rubber is put into the feed inlet 9 and then into the feed device 4. The motor 11 is started and drives the primary crushing mechanism 13 and the secondary crushing mechanism 16 to rotate through the rotating shaft 12. Then, after being crushed by the primary crushing mechanism 13, the rubber passes through the first through hole 14 and enters the secondary crushing mechanism 16. After being crushed by the secondary crushing mechanism 16, it passes through the second through hole 17 and enters the discharge box 2. Finally, it enters the collection box 5 through the steep slope 10 of the discharge box 2. In the collection box 5, it is sent to the desulfurization tank 7 by the conveyor belt device 6 for desulfurization. After desulfurization, it is sent to the recycling box 8 by the conveyor belt device 6.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
