Description

Technical Field

[0001] This invention relates to the field of waste rubber recycling and softening technology, specifically to a waste rubber recycling and softening device. Background Technology

[0002] With the continuous development of productivity, my country has become one of the world's largest producers of waste rubber. Waste rubber can be used in many fields, such as the production of paper and steel. Existing waste rubber recycling equipment has a simple structure and takes a long time to crush the waste rubber, resulting in low recycling efficiency. In addition, traditional methods of waste rubber disposal, such as landfill and incineration, cause environmental pollution and affect health. As society's requirements for the environment become higher and higher, and with the implementation of sustainable development policies, it is necessary to recycle and reuse waste rubber to save resources and protect the environment.

[0003] Rubber is a highly elastic polymer material with reversible deformation. It is a completely amorphous polymer and is a final product made from a plastic semi-finished product through vulcanization. Rubber will age after long-term use, thus generating a lot of waste rubber. When recycling waste rubber, a special softening device is often needed for its recycling.

[0004] In the field of rubber softening technology, the most common method is to soften rubber by heating. During heating, in order to ensure that all parts of the rubber are heated evenly, the rubber needs to be broken up and then the rubber fragments are added to the heating chamber in small amounts multiple times. Because the rubber fragments need to be added to the heating chamber multiple times, the opening of the heating chamber needs to be opened continuously. This causes heat to be lost from the heating chamber, thereby reducing the heating efficiency of the heating chamber on the rubber and affecting the rubber softening process.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] I. This invention further increases the heat-receiving area of ​​waste rubber by crushing it and allowing the crushed waste rubber to fall into the bottom of the drying oven and spread out, thereby further improving the softening effect of the waste rubber.

[0029] Second, in this invention, only one of the baffle plates (first and second) will be open during operation. Furthermore, the bellows-like protective cover ensures that the oven remains in a relatively enclosed environment during the reciprocating feeding process. This reduces heat loss within the oven and further improves the heating efficiency of the rubber scraps. Simultaneously pushing the closed baffle plates upwards also causes the rubber above the first baffle plate to move upwards, allowing the rubber scraps to undergo secondary crushing by the crushing wheel, further enhancing the crushing effect, increasing the heating area of ​​the rubber, and improving the softening effect.

[0030] Third, this invention uses fixed columns two and three to bring trapezoidal blocks one and two closer together, pressing the waste rubber onto the surface of the crushing wheel, thus improving the crushing effect. Furthermore, the trapezoidal blocks one and two only move closer together during the downward movement of connecting plate one, which allows sufficient reserve material to accumulate above the blocking plate one, making ample preparation for the next feeding. This further solves the problem of uneven feeding of the drying oven caused by uneven crushing efficiency.

[0031] Fourth, after the first and second baffle plates are closed to measure the waste rubber, the present invention sprays the softening catalyst in the catalyst box through the nozzle to further improve the softening efficiency of the waste rubber. At the same time, the rubber fragments between the first and second baffle plates are stirred by driving the stirring blades to rotate.

[0032] Furthermore, as the closed baffle plate one and baffle plate two continue to move downwards, they can drive the rubber fragments between the baffle plate one and baffle plate two to move downwards, thereby allowing the stirring blades to stir the rubber fragments at different positions. This ensures that the rubber fragments between the baffle plate one and baffle plate two can fully contact the softening catalyst when the softening catalyst is sprayed, thus improving the softening effect on waste rubber.

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Example 1, please refer to Figures 1 to 11 This embodiment provides a technical solution: a waste rubber recycling and softening device, including an oven 1, a shield 3 fixedly connected to the surface of the oven 1, a feeding pipe 5 fixedly connected to the upper end face of the oven 1, a feeding trough 4 fixedly connected to the upper end face of the feeding pipe 5, and a crushing wheel 33 provided on the inner wall of the upper end face of the feeding pipe 5, a support leg 9 fixedly connected to the lower surface of the oven 1, an electronic pressure relief valve 2 fixedly connected to the side of the oven 1, a control panel 7 fixedly connected to the upper end face of the oven 1, a door 8 connected to the side of the oven 1, and a collection plate 44 slidably connected inside the oven 1.

[0047] In this embodiment, the recycled waste rubber is placed into the feeding trough 4, and then the crushing wheel 33 is activated to crush the waste rubber. The crushed waste rubber then falls into the bottom of the drying oven 1 through the feeding pipe 5 to be dried. The waste rubber falling into the bottom of the drying oven 1 will be scattered at the bottom of the drying oven 1, thereby receiving sufficient heating and softening the waste rubber. Furthermore, an electronic pressure relief valve 2 is also provided on the drying oven 1. Since the rubber will produce gas during the heating process, the accumulation of this gas will increase the gas pressure inside the drying oven 1. The electronic pressure relief valve 2 can better protect the drying oven 1 and prevent damage to the drying oven due to excessive gas pressure.

[0048] By crushing the waste rubber and allowing the crushed waste rubber to fall into the bottom of the oven 1 and spread out, the heating area of ​​the waste rubber is increased, as well as the softening effect of the waste rubber.

[0049] It is worth noting that the waste rubber recycling and softening device also includes a quantitative feeding assembly, which is installed on the feeding pipe 5. The quantitative feeding assembly includes:

[0050] The upper end face of the oven 1 is provided with a fixed block 11 and an electric push rod 10. The output end of the electric push rod 10 is fixedly connected to the lower end face of the fixed block 11. A connecting plate 12 is fixedly connected to the side of the fixed block 11. A through sliding groove 30 is opened on the end surface of the connecting plate 12. A spring 28 is fixedly connected to the groove wall of the sliding groove 30. An abutment block 27 is fixedly connected to the other end face of the spring 28. A rotating column 26 is rotatably connected to the surface of the abutment block 27. The surface of the rotating column 26 is also slidably connected to the groove wall of the sliding groove 30.

[0051] Fixed plate 31, the side of fixed plate 31 is fixedly connected to the outer side of feeding pipe 5, Y-shaped groove 29 is opened on the end face of fixed plate 31, the groove wall of Y-shaped groove 29 is slidably connected to the surface of rotating column 26, sliding column 24 is also slidably connected to the groove wall of Y-shaped groove 29, connecting plate 25 is fixedly connected to the end surface of sliding column 24 and the end surface of rotating column 26, arc frame 34 is fixedly connected to the side of connecting plate 25, and blocking plate 41 is fixedly connected to the end face of arc frame 34 away from connecting plate 25.

[0052] Fixed plate 2 36, the upper end face of fixed plate 2 36 is fixedly connected to the lower end face of fixed plate 1 31, the side of fixed plate 2 36 is fixedly connected to the outer surface of feeding pipe 5, a Y-shaped groove 2 38 is opened on the end face of fixed plate 2 36, a sliding column 3 35 is slidably connected to the groove wall of Y-shaped groove 2 38, a sliding column 4 37 is provided below the sliding column 3 35, the surface of sliding column 4 37 is slidably connected to the groove wall of Y-shaped groove 2 38, a connecting plate 3 52 is fixedly connected to the end surface of sliding column 3 35 and the end surface of sliding column 4 37, an arc frame 2 39 is fixedly connected to the side of connecting plate 3 52, a blocking plate 2 40 is fixedly connected to the end surface of arc frame 2 39 away from connecting plate 3 52, and the blocking plate 2 40 is located below the blocking plate 1 41;

[0053] The side of the connecting plate 25 is fixedly connected to the three curved rods 53 and the connecting column 54. The upper end of the three curved rods 53 is hinged to the end surface of the connecting column 54, and the lower end of the three curved rods 53 is hinged to the end surface of the sliding column 35.

[0054] The inner wall of the feeding pipe 5 of the bellows cover 32 has a through slot, the wall of the slot is fixedly connected to the end of the bellows cover 32, and the other end of the bellows cover 32 is fixedly connected to the surface of the arc frame 34. The surface of the arc frame 39 is also provided with the bellows cover 32.

[0055] In this embodiment, by activating the electric push rod 10, the connecting plate 12 is driven to move up and down repeatedly, so that the blocking plate 41 and the blocking plate 40 have the following three motion states:

[0056] Firstly: When the electric push rod 10 drives the connecting plate 12 to move downwards, under the action of the Y-shaped groove 29, the connecting plate 25 is deflected, and at the same time, the connecting column 54 presses the abutment block 27. Then, the abutment block 27 presses the spring 28, and through the arc frame 34, the two blocking plates 41 are brought together to prevent the waste rubber scraps from falling between the blocking plate 41 and the blocking plate 40, thus completing the quantitative operation of the waste rubber scraps.

[0057] Secondly, the electric push rod 10 continues to drive the connecting plate 12 to move downwards, and under the action of the crank rod 53, it drives the sliding column 35 and the sliding column 47 to slide in the Y-shaped groove 38, so that the closed blocking plate 1 41 and the blocking plate 2 40 continue to move downwards. When the blocking plate 2 40 moves to the bottom, the crank rod 53 pushes the connecting plate 3 52 and the arc frame 2 39 to deflect around the sliding column 4 37, so that the blocking plate 2 40 opens, and the waste rubber scraps between the blocking plate 1 41 and the blocking plate 2 40 will fall into the oven 1 to soften.

[0058] Thirdly: When the electric push rod 10 drives the connecting plate 12 to move upward, in the opposite direction of the above movement, under the action of the Y-shaped groove 38, the blocking plate 40 will first merge together, and then simultaneously push the closed blocking plate 41 and the blocking plate 40 to move upward, driving the rubber above the blocking plate 41 to move upward, so that the rubber fragments can be crushed by the crushing wheel 33, improving the crushing effect. Finally, after the blocking plate 41 moves to the top, the elastic force of the spring 28 is released, and then under the action of the Y-shaped groove 29, the connecting plate 25 rotates around the sliding column 24 as the axis, and the two blocking plates 41 are opened through the arc frame 34, and the waste rubber fragments fall between the blocking plate 41 and the blocking plate 40, repeating the first movement state;

[0059] By reciprocating the electric push rod 10, continuous quantitative feeding of materials into the oven 1 can be achieved.

[0060] The quantitative feeding assembly is designed so that at most one of the baffle plates 41 and 40 will be open during operation. With the help of the bellows cover 32, the oven 1 is kept in a relatively closed environment during the reciprocating feeding process, which reduces the heat loss inside the oven 1 during feeding and improves the heating efficiency of the rubber scraps. When the baffle plates 41 and 40 are pushed to move upward at the same time, the rubber above the baffle plate 41 will also move upward, so that the rubber scraps can be crushed twice by the crushing wheel 33, which further improves the crushing effect, increases the heating area of ​​the rubber, and improves the softening effect.

[0061] Example 2, based on the above examples:

[0062] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The waste rubber recycling and softening device also includes a rubber pressing assembly, which is installed on the feeding pipe 5. The rubber pressing assembly includes:

[0063] A fixed frame 13 is fixedly connected to the upper end of a connecting plate 12. A curved rod 20 is hinged to the upper end of the fixed frame 13. A fixed column 21 is hinged to the end of the curved rod 20 away from the fixed frame 13. A trapezoidal block 23 is fixedly connected to the end face of the fixed column 21. The surface of the trapezoidal block 23 is slidably connected to the upper inner wall of the feeding pipe 5. A curved rod 19 is also hinged to the upper end of the fixed frame 13. A fixed column 18 is hinged to the end of the curved rod 19 away from the fixed frame 13. A trapezoidal block 15 is fixedly connected to the end face of the fixed column 18. The surface of the trapezoidal block 15 is also slidably connected to the upper inner wall of the feeding pipe 5. A sliding groove 17 penetrating into the interior is opened on the upper surface of the feeding pipe 5. The surface of the sliding groove 17 is slidably connected to the surface of the fixed column 21. The surface of the sliding groove 17 is also slidably connected to the surface of the fixed column 18.

[0064] Limiting post 22, the end face of limiting post 22 is fixedly connected to the side of trapezoidal block 23, the inclined surface of trapezoidal block 23 is provided with misaligned tooth 42, the inclined surface of trapezoidal block 25 is provided with misaligned tooth 43, misaligned tooth 42 can mesh with the tooth surface of misaligned tooth 43, and limiting post 26 is also fixedly connected to the side of trapezoidal block 25. The upper end surface of the feeding pipe 5 is provided with a limiting groove 14 that penetrates into the interior, and the groove wall of the limiting groove 14 is slidably connected to the surface of limiting post 22 and the surface of limiting post 26.

[0065] In this embodiment, as the electric push rod 10 drives the connecting plate 12 to move up and down repeatedly, it further drives the fixed frame 13 to move up and down. The up and down movement of the fixed frame 13 causes the included angle between the crank rod 20 and the crank rod 19 to change. This causes the trapezoidal block 23 and the trapezoidal block 15 to move closer together through the fixed column 21 and the fixed column 3 18, pressing the waste rubber onto the surface of the crushing wheel 33, further improving the crushing effect. Moreover, the trapezoidal block 23 and the trapezoidal block 15 only move closer together when the connecting plate 12 moves down. This allows a sufficient amount of reserve material to accumulate above the blocking plate 41, making sufficient preparation for the next feeding and solving the problem of uneven feeding of the oven 1 due to uneven crushing efficiency.

[0066] Example 3, based on the above examples:

[0067] Please see Figure 1 , Figure 2 , Figure 7 and Figure 9 The waste rubber recycling and softening device also includes a catalytic component, which is installed inside the feed pipe 5. The catalytic component includes:

[0068] Catalyst box 6, the lower end face of catalyst box 6 is fixedly connected to the upper end face of oven 1, a nozzle 47 is provided below the baffle plate 41, the tail of nozzle 47 is fixedly connected to a fixing pipe 45, and the other end of fixing pipe 45 is fixedly connected to the interior of catalyst box 6.

[0069] In this embodiment, after the first baffle plate 41 and the second baffle plate 40 are closed to quantify the waste rubber, the softening catalyst in the catalyst box 6 is sprayed out through the nozzle 47, thereby further improving the softening efficiency of the waste rubber.

[0070] Example 4, based on the above examples:

[0071] Please see Figure 7 , Figure 8 , Figure 9 and Figure 10 The waste rubber recycling and softening device also includes an agitation component, which is installed inside the feeding pipe 5. The agitation component includes:

[0072] A straight toothed rack 51 has its back tooth surface rotatably connected to the end face of the rotating column 24. A limiting plate 50 is fixedly connected to the side of the straight toothed rack 51. The lower end face of the limiting plate 50 is fixedly connected to the upper end face of the oven 1. A toothed ring 49 is meshed with the tooth surface of the straight toothed rack 51. A rotating rod 46 is fixedly connected to the inner wall of the toothed ring 49. The rotating rod 46 is located above the baffle plate 240, and its surface rotates through the surface of the feeding pipe 5. An agitator blade 48 is fixedly connected to the surface of the rotating rod 46 inside the feeding pipe 5.

[0073] In this embodiment, as the electric push rod 10 drives the connecting plate 12 to move up and down, it will further drive the straight tooth row 51 to move up and down. The straight tooth row 51 drives the tooth ring 49 to rotate. The rotation of the tooth ring 49 will drive the rotating rod 46 to rotate. The rotation of the rotating rod 46 will further drive the stirring blade 48 to rotate, thus stirring the rubber fragments between the blocking plate 41 and the blocking plate 40.

[0074] Moreover, when the closed baffle plate 1 41 and baffle plate 2 40 continue to move downward, they can drive the rubber fragments between the baffle plate 1 41 and baffle plate 2 40 to move downward, so that the stirring blade 48 can stir the rubber fragments at different positions, so that the rubber fragments between the baffle plate 1 41 and baffle plate 2 40 can fully contact the softening catalyst when the softening catalyst is sprayed, thereby improving the softening effect on waste rubber.

[0075] This agitator assembly, by driving the agitator blade 48 to rotate, stirs the rubber fragments between the first baffle plate 41 and the second baffle plate 40. As the closed baffle plates 41 and 40 continue to move downward, they also cause the rubber fragments between them to move downward. This allows the agitator blade 48 to stir the rubber fragments at different locations, ensuring that the rubber fragments between the first baffle plate 41 and the second baffle plate 40 can fully contact the softening catalyst when it is sprayed, thereby improving the softening effect on waste rubber.

[0076] Working principle: This waste rubber recycling and softening device has the following steps when in use:

[0077] S1: Put the recycled waste rubber into the feeding trough 4, and then start the crushing wheel 33 to crush the waste rubber. The crushed waste rubber will enter between the first baffle 41 and the second baffle 40 through the unclosed baffle 41.

[0078] S2: Next, start the electric push rod 10 to drive the connecting plate 12 to move downward, first making the two blocking plates 41 close together to complete the quantitative operation of waste rubber scraps.

[0079] S3: The closed baffle plate 1 41 and baffle plate 2 40 move downwards, triggering the nozzle 47 through the control panel 7 to spray the softening catalyst in the catalyst box 6 into the space between baffle plate 1 41 and baffle plate 2 40.

[0080] S4: As the first baffle plate 41 and the second baffle plate 40 move downwards, they drive the stirring blade 48 to rotate, stirring the rubber fragments between the first baffle plate 41 and the second baffle plate 40, thereby cooperating with the nozzle 47 to allow the softening catalyst to mix better with the rubber fragments.

[0081] S5: Under the action of the electric push rod 10, the first baffle plate 41 and the second baffle plate 40 move downward together. When they reach the bottom, the second baffle plate 40 opens, allowing the rubber scraps to fall into the oven 1 for heating and softening. Under the operation of the electric push rod 10, multiple indirect feedings are achieved into the oven 1. Finally, the softened rubber can be taken out.
