Description

A device for recycling recycled rubber granules Technical Field

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

[0002] Rubber waste recycling is the process of recovering and reusing waste rubber products and materials. Currently, in the recycling and reprocessing of rubber waste, the waste must first be crushed, and then the crushed rubber raw material must be screened to obtain rubber granules with a particle size that meets the standards. However, in the actual screening process of rubber granules, the screens of common rubber recycling devices are generally made of mesh materials produced by weaving or welding processes, and their pore size cannot be adjusted. Because the pore size is fixed, when it is necessary to screen rubber granules of different sizes, it can only be achieved by changing to screens of different specifications; and when the screen is clogged, it usually needs to be disassembled and cleaned. This makes the process of replacing and cleaning the screens in existing rubber recycling devices quite cumbersome. To address the above problems, this invention proposes a recycled rubber granule recycling device. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a recycled rubber granule recycling device with easily adjustable pores to meet different screening requirements and easy cleaning when the pores are blocked.

[0004] This invention is achieved through the following technical solution:

[0005] A recycled rubber granule recycling device includes a crushing mechanism for preparing waste rubber into rubber granules and a filtering mechanism for filtering the rubber granules. The filtering mechanism includes a central frame and multiple mesh rods. The multiple mesh rods are arranged circumferentially along the central frame to form a conical filter screen. The gaps between adjacent mesh rods form strip-shaped filter pores. The multiple mesh rods are rotatably connected to the central frame so that the width of the filter pores is adjustable. The angle between the multiple mesh rods and the central frame is adjusted by an angle adjuster.

[0006] Optionally, the angle adjuster includes a support portion for supporting the multiple network poles and a drive portion for driving the support portion to move vertically.

[0007] Optionally, the support includes a sliding member and a connecting rod. The sliding member is slidably disposed on the intermediate upright, and the connecting rod is rotatably connected between the sliding member and the multiple network poles. The driving part is used to drive the sliding member to slide along the vertical direction.

[0008] Optionally, the driving unit is a first electric lead screw, which includes a first lead screw and a first motor that drives the first lead screw to rotate, and the sliding member is threadedly engaged with the first lead screw.

[0009] Optionally, the support part is a plurality of annular support rings with different diameters, the plurality of support rings simultaneously supporting the plurality of network poles, and the driving part is used to drive the plurality of support rings to move synchronously and in the same direction but at different speeds along the vertical axis.

[0010] Optionally, the driving unit is a second electric lead screw, which includes a second lead screw and a second motor that drives the second lead screw to rotate. The second lead screw is provided with multiple external threads with different pitches, and the multiple support rings are respectively connected to the multiple external threads.

[0011] Optionally, the width of the filter pores gradually increases from one end near the middle support to the other end. The filter mechanism also includes a receiving container, which is located below the conical filter screen. The receiving container has multiple receiving areas with the same center but different diameters inside.

[0012] Optionally, the intermediate support frame is rotatable about a rotation axis passing through the center of the plurality of receiving areas. The filtering mechanism further includes a pusher frame and a discharge port. The pusher frame is fixed on the intermediate support frame and has a pusher part extending into the receiving area. The discharge port is located at the bottom of the receiving area.

[0013] Optionally, each receiving area is provided with a pusher and a discharge port, and the discharge ports of adjacent receiving areas are respectively located on opposite sides of the intermediate upright.

[0014] Optionally, the filtration mechanism further includes a receiving trough, which has multiple collection areas corresponding one-to-one with the multiple discharge ports.

[0015] Compared with the prior art, the present invention provides a reclaimed rubber granule recycling device, which has the following beneficial effects:

[0016] 1. By setting an adjustable filter pore width, the present invention can solve the problems of screening rubber particles of different sizes and screening blockage by adjusting the width of the filter pores. It does not require disassembling and replacing the conical filter screen of the filter mechanism, and has the advantages of being more adaptable and easier to clean blockages.

[0017] 2. By setting multiple support rings of different diameters to jointly support the mesh rod, the deformation of the mesh rod under the pressure of rubber particles can be reduced, thus ensuring the stability of the filter gap width. By moving multiple support rings vertically in a synchronous, unidirectional but different speed manner, the multiple support rings can always jointly support the mesh rod when the angle between the mesh rod and the intermediate stand changes.

[0018] 3. By setting the width of the filter pores to gradually increase from one end near the middle support to the other end, and by setting a receiving container with multiple receiving areas with the same center but different diameters inside, the present invention can realize multi-stage screening of rubber particles, so that the rubber particles are loaded into different receiving areas according to their particle size, thereby meeting the requirements for multi-stage screening of rubber particles.

[0026] 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.

[0027] As described in the background section, the screens of common rubber recycling devices are generally made of mesh material through weaving or welding processes. The size of the pores cannot be adjusted. Because the pore size is fixed, when it is necessary to screen rubber particles of different sizes, it can only be achieved by replacing the screen with a different specification. When the screen is clogged, it is usually necessary to disassemble and clean the screen. This makes the process of replacing and cleaning the screens in existing rubber recycling devices quite cumbersome.

[0028] To address the aforementioned problems, the following embodiment is provided: Referring to Figures 1 to 6, this embodiment of the invention provides a recycled rubber granule recycling device. It mainly includes a crushing mechanism for preparing waste rubber into rubber granules and a filtering mechanism for filtering the rubber granules. The filtering mechanism includes a central support frame 300, multiple mesh rods 310, and an angle adjuster. The multiple mesh rods 310 are arranged circumferentially along the central support frame 300 to form a conical filter screen 311. The gaps between adjacent mesh rods 310 form strip-shaped filter pores 312. The multiple mesh rods 310 are rotatably connected to the central support frame 300 so that the width of the filter pores 312 is adjustable. The mesh rods 310 can be connected to the central support frame 300 via a rotating shaft. The angle between the multiple mesh rods 310 and the central support frame 300 is adjusted by the angle adjuster, allowing the width of the filter pores 312 to change with the angle between the multiple mesh rods 310 and the central support frame 300.

[0029] With the above configuration, the conical filter screen 311 of the filtration mechanism can screen rubber particles. Smaller rubber particles fall through the filter pores 312 to the bottom of the conical filter screen 311, while larger rubber particles slide down the inclined surface of the conical filter screen 311 to the peripheral area, thus achieving the screening of rubber particles. When it is necessary to screen rubber particles of different sizes, this can be achieved by adjusting the width of the filter pores 312; when it is necessary to clean the conical screen, the width of the filter pores 312 can be increased, causing the rubber particles clogging the filter pores 312 to fall out automatically as the width of the filter pores 312 increases. Therefore, this recycled rubber particle recovery device can solve the problems of screening rubber particles of different sizes and clogging by adjusting the width of the filter pores 312, without disassembling or replacing the conical filter screen 311 of the filtration mechanism. It has the advantages of greater adaptability and easier clogging removal.

[0030] As shown in Figure 2, in some embodiments, the crushing mechanism and the filtering mechanism are respectively located in the upper half 110 and the lower half 120 inside a housing 100. The portion connecting the upper half 110 and the lower half 120 is the middle part 130. The crushing mechanism includes a blade assembly disposed inside the housing 100 and a crushing motor 200 disposed outside the housing 100 for driving the blade assembly. The blade assembly includes a crushing blade 210 disposed in the upper half 110 of the housing 100 and a spiral conveying blade 220 disposed in the middle part 130 of the housing 100. The crushing blade 210 is used to crush rubber waste into rubber particles, and the conveying blade 220 is used to push the rubber particles from the upper half 110 to the lower half 120. The housing 100 is provided with a feeding port 140 for convenient addition of rubber waste to the upper half 110 of the housing 100. Two feeding ports 140 can be provided. With the above setup, rubber waste enters the upper part 110 of the housing 100 through the feeding port 140, is crushed into rubber particles by the crushing mechanism, and the rubber particles enter the lower part 120 of the housing 100 through the conveying knife 220, are screened by the filtering mechanism, and thus obtain rubber particles of standard particle size.

[0031] As shown in Figure 2, in some embodiments, to achieve better screening results, the conical filter screen 311 is positioned directly below the middle portion 130 within the housing 100. When rubber particles fall from the middle portion 130, they slide outwards along the conical surface of the conical filter screen 311, thus reducing clogging problems caused by the accumulation of rubber particles.

[0032] As shown in Figure 2, in some embodiments, to prevent rubber particles from accumulating on the top of the intermediate support 300 and to avoid the rubber particles obstructing the rotation of the mesh rod 310, a cone 301 is provided at the top of the intermediate support 300, and the mesh rod 310 is connected to the bottom of the cone 301.

[0033] As shown in Figure 2, to adjust the angle between the multiple mesh poles 310 and the intermediate support frame 300, in some embodiments, the angle adjuster includes a support portion 400 for supporting the multiple mesh poles 310 and a drive portion 410 for driving the support portion 400 to move vertically, where vertical is the direction of gravity of the rubber particles. With this configuration, the drive portion 410 can drive the support portion 400 to move vertically, thereby achieving the purpose of adjusting the angle between the multiple mesh poles 310 and the intermediate support frame 300. In other embodiments, the angle adjuster can also be a cylinder or hydraulic cylinder rotatably connected between the mesh poles 310 and the intermediate support frame 300.

[0034] As shown in Figures 3 and 4, in some embodiments, the support 400 includes a sliding member 401 and a connecting rod 402. The sliding member 401 is slidably mounted on the intermediate support 300. The connecting rod 402 is rotatably connected between the sliding member 401 and the multiple mesh rods 310. The connecting rod 402 and the sliding member 401, as well as the connecting rod 402 and the mesh rods 310, can be rotatably connected via a pivot. The driving unit 410 is used to drive the sliding member 401 to slide vertically. When adjusting the angle between the multiple mesh rods 310 and the intermediate support 300, the driving unit 410 drives the sliding member 401 to slide. The sliding member 401 drives the mesh rods 310 to rotate via the connecting rod 402, thereby changing the angle between the mesh rods 310 and the intermediate support 300.

[0035] As shown in Figure 4, to enable the sliding member 401 to slide vertically, in some embodiments, the driving unit 410 is a first electric lead screw, which includes a first lead screw 411 and a first motor 412 that drives the first lead screw 411 to rotate. The sliding member 401 is threadedly engaged with the first lead screw 411. In a specific implementation, the intermediate support 300 has a hollow structure inside. The first motor 412 and the first lead screw 411 are installed inside the intermediate support 300. The sliding member 401 has an external portion 4010 located outside the intermediate support 300, an internal portion 4011 located inside the intermediate support 300, and a connecting portion 4012 connecting the external portion 4010 and the internal portion 4011. The external portion 4010 is connected to the connecting rod 402, and the internal portion 4011 is connected to the first lead screw 411. The intermediate support 300 has a groove that slides with the connecting portion 4012. When the first motor 412 starts, it drives the first lead screw 411 to rotate, and the first lead screw 411 drives the sliding member 401 to move vertically.

[0036] As shown in Figures 5 and 6, in some embodiments, the support portion 400 consists of multiple annular support rings 403 of different diameters. These support rings 403 simultaneously support multiple mesh rods 310. The drive portion 410 drives the multiple support rings 403 to move synchronously and in the same direction vertically, but at different speeds. When adjusting the angle between the multiple mesh rods 310 and the intermediate support frame 300, the drive portion 410 drives the multiple support rings 403 to move synchronously and in the same direction vertically, but at different speeds. The multiple support rings 403 push the mesh rods 310 to rotate, thereby changing the angle between the mesh rods 310 and the intermediate support frame 300. The multiple support rings 403 of different diameters jointly supporting the mesh rods 310 can reduce the deformation of the mesh rods 310 under the pressure of the rubber particles, ensuring the stability of the filter gap width. By moving multiple support rings 403 vertically in a synchronous, unidirectional but different speed manner, the multiple support rings 403 can always jointly support the network pole 310 when the angle between the network pole 310 and the intermediate support frame 300 changes.

[0037] As shown in Figure 6, to achieve synchronous, unidirectional but different speed vertical movement of multiple support rings 403, in some embodiments, the driving unit 410 is a second electric lead screw, which includes a second lead screw 413 and a second motor 414 that drives the second lead screw 413 to rotate. The second lead screw 413 is provided with multiple external threads of different pitches, and the multiple support rings 403 are respectively connected to the multiple external threads. In a specific implementation, the intermediate support frame 300 has a hollow structure inside. The second motor 414 and the second lead screw 413 are installed inside the intermediate support frame 300. The second lead screw 413 is connected to a nut 415, and the nut 415 is connected to the support ring 403 through a connecting rod 416. The intermediate support frame 300 is provided with a sliding groove that slides with the connecting rod 416. When the second motor 414 starts, it drives the second lead screw 413 to rotate. The second lead screw 413 drives the nut 415, connecting rod 416 and support ring 403 to move vertically. Because the pitch of the multiple external threads on the second lead screw 413 is different, the multiple support rings 403 can move vertically in a synchronous, same direction but different speed manner.

[0038] As shown in Figure 2, in some embodiments, the width of the filter pores 312 gradually increases from one end near the central support 300 to the other end. The filter mechanism also includes a receiving container 320, which is located below the conical filter screen 311. The receiving container 320 has multiple receiving areas 321 with the same center but different diameters inside. This arrangement allows for multi-stage screening of rubber particles, enabling the rubber particles to be loaded into different receiving areas 321 according to their particle size, thus meeting the requirements for multi-stage screening of rubber particles.

[0039] As shown in Figure 2, in some embodiments, the intermediate support 300 is rotatable about a rotation axis passing through the center of multiple receiving areas 321. The rotation of the intermediate support 300 about the rotation axis can be achieved by a pusher motor 330. The filtering mechanism also includes a pusher frame 340 and a discharge port 350. The pusher frame 340 is fixed on the intermediate support 300 and has a pusher part 341 extending into the receiving area 321. The receiving container 320 is fixed to the housing 100, and the discharge port 350 is located at the bottom of the receiving area 321. With this configuration, when it is necessary to remove the rubber granules from the receiving container 320, the intermediate support 300 is rotated. The intermediate support 300 drives the pusher 340 to rotate, and the pusher 340 pushes the rubber granules to move within the receiving area 321 of the receiving container 320. When the rubber granules move to the discharge port 350, they can be smoothly discharged. In this way, the screened rubber granules in the receiving container 320 can be easily removed. It should be noted that in this embodiment, the first motor 412 or the second motor 414 can be connected to an external circuit via an electric slip ring.

[0040] As shown in Figure 2, in some embodiments, each receiving area 321 is provided with a pusher 341 and a discharge port 350, and the discharge ports 350 of adjacent receiving areas 321 are respectively located on opposite sides of the intermediate support 300. This allows multiple discharge ports 350 to be arranged side by side and maintains a large distance between adjacent discharge ports 350 to prevent the mixing of rubber particles of different sizes during material collection.

[0041] As shown in Figure 2, in some embodiments, the filtration mechanism further includes a receiving trough 360, which has multiple collection areas 361 corresponding to multiple discharge ports 350. The multiple collection areas 361 can collect the rubber particles in the multiple receiving areas 321 separately, reducing material mixing.

[0042] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
