Description

Technical Field

[0001] This invention relates to the field of shredding equipment technology, and more particularly to a tire shredding device. Background Technology

[0002] To facilitate tire recycling, tires need to be crushed. For example, my country is a major tire manufacturer and consumer, with tire production consuming 70% of the country's total rubber consumption annually. The rubber products industry relies on imports for 80% of its natural rubber and 30% of its synthetic rubber. Industrial development is accompanied by a massive generation of waste tires. Statistics show that over 60% of my country's waste rubber comes from waste tires, and waste tires account for only 20% of recycled waste rubber. The ever-increasing amount of waste tires not only occupies space resources but also easily causes environmental pollution. Therefore, the recycling of waste tires is of great significance to the sustainable development of industry. Tire recycling requires crushing tires into rubber powder. Existing methods for crushing tires mainly include chemical methods, mechanical methods, and water jet methods.

[0003] In the waterjet method, water is used to impact the tire tread, turning the tire into rubber powder, thus breaking it down. However, the impact often results in water and rubber powder splashing everywhere, making it difficult for workers to handle. Furthermore, because the water jet impacts the tire tread, the tire sidewalls are not adequately impacted, leading to lower efficiency in sidewall breaking. Summary of the Invention

Detailed Implementation

[0058] This invention provides a tire shredding device for efficiently shredding the sidewall of a tire 1.

[0059] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0060] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0061] Figure 1 This is a front view of a tire shredding device provided in an embodiment of the present invention. Figure 2 for Figure 1 The image shows a right view of the tire shredder. Figure 3 for Figure 2 This is a schematic diagram of a cross-section of a tire shredding device. Wherein, in Figure 3 In the process, a section of the tire shredding equipment was cut open.

[0062] See Figure 1 , Figure 2 and Figure 3 The tire shredding equipment of this invention includes a shredding chamber 8 and a water jet assembly 2.

[0063] The crushing chamber 8 is a box structure used to crush the tire 1. The crushing chamber 8 includes a crushing cavity 9, which is a hollow cavity and specifically a closed structure to prevent water and rubber powder from splashing out. A water jet assembly 2 is installed inside the crushing cavity 9, and the water jet assembly 2 includes a water jet 3.

[0064] The crushing cavity 9 includes a tire crushing area 10, which is used to house the tire 1. In other words, the tire crushing area 10 is a spatial area in which the tire 1 to be crushed is housed.

[0065] The water jet 3 is located on the side of the tire shattering area 10, and the side of the tire shattering area 10 is opposite to the tire sidewall of the tire 1. Specifically, after the tire 1 to be shattered is placed in the tire shattering area 10, the side of the tire shattering area 10 is opposite to the tire sidewall of the tire 1. Because the water jet 3 is located on the side of the tire shattering area 10, the water jet 3 is relatively close to the tire sidewall of the tire 1, which facilitates the water jet 3 to fully impact the tire sidewall of the tire 1.

[0066] The water jet 3 is used to spray water through its nozzles 4 onto the sidewall of the tire 1 located in the tire shredding zone 10 to shred the tire 1. Specifically, the water jet 3 includes nozzles 4 that can spray water. After the tire 1 to be shredded is placed in the tire shredding zone 10, the nozzles 4 of the water jet 3 spray water onto the sidewall of the tire 1, shredding the rubber part of the tire 1 into rubber powder.

[0067] When shredding tire 1, because tire 1 is housed within the tire shredding area 10, and the water jet 3 is located on the side of the tire shredding area 10, the water jet 3 can approach the sidewall of tire 1. When the nozzle 4 of the water jet 3 sprays water onto the sidewall of tire 1, the water jet from the nozzle 4 of the water jet 3 can fully impact the sidewall of tire 1, thereby efficiently shredding the sidewall of tire 1. The shredding process of tire 1 takes place within the shredding chamber 9 of the shredding box 8. Because the shredding box 8 is a box structure, it forms a closed environment, which can prevent water and rubber powder from splashing out of the shredding box 8 during the tire shredding process, thus facilitating the shredding operation of tire 1. In this way, efficient shredding of the sidewall of tire 1 is achieved.

[0068] The water jet 3 of this invention operates on the following principle: the nozzle 4 of the water jet 3 sprays a water stream, which can be an ultra-high-pressure water stream. The impact kinetic energy of this water stream cuts the rubber portion of the tire 1. By adjusting the water pressure, the cutting energy of the water stream can be adjusted to break only the rubber on the tire 1, turning it into fine rubber powder, without damaging the steel wires within the tire 1. This process cuts the rubber portion of the tire 1 into rubber powder using the water jet, while the steel wires of the tire 1 are completely preserved. Thus, the rubber and steel wires of the tire 1 are separated at high speed with relatively low energy, and the separated rubber can be directly used to generate recyclable industrial rubber powder.

[0069] To better prevent water and adhesive powder from splashing, optionally, such as Figure 4 and Figure 5 As shown, the tire shredding equipment also includes a water barrier layer 11, which is installed inside the shredding cavity 9 and separates the tire shredding area 10 and the water jet assembly 2.

[0070] The surface of the water-retaining layer 11 is provided with a groove 12, which penetrates the water-retaining layer 11. This groove 12 allows the water jet nozzle 4 of the water jet 3 to pass through, so that the nozzle 4 is directed towards the tire breakage area 10, and thus towards the sidewall of the tire 1 located in the tire breakage area 10. By spraying water from the nozzle 4 onto the sidewall of the tire 1, the sidewall of the tire 1 can be broken.

[0071] When the water jet from nozzle 4 impacts tire 1, the rubber on tire 1 turns into rubber powder. At this time, water and rubber powder will splash up. Because the water-blocking layer 11 separates the tire shredding area 10 and the water jet assembly 2, some water and rubber powder are blocked by the water-blocking layer 11, reducing the splashing of water and rubber powder. This helps to reduce the splash protection burden on the shredding chamber 8, thereby better achieving the splash protection of water and rubber powder by the tire shredding equipment.

[0072] To further reduce water and adhesive powder splashing out of the crushing chamber 8, optionally, such as Figure 4 As shown, the slot 12 is sealed by the skin structure 21, which has a skin gap for the water jet nozzle 4 to pass through. The skin structure 21 is a flexible structure, specifically made of plastic. Specifically, the skin structure 21 seals the slot 12, and the water jet nozzle 4 of the water jet 3 passes through the skin gap, thus passing through the slot 12. This nozzle 4 faces the tire breakage area 10. In this way, the skin structure 21 seals the gap between the slot 12 and the nozzle 4, preventing water and adhesive powder from splashing out and facilitating the cleaning of water and adhesive powder from the skin structure 21. Furthermore, because the skin structure 21 is flexible, it prevents collision damage to the nozzle 4.

[0073] Optionally, the water jet assembly 2 can be installed on the water-blocking layer 11, or, to increase installation rigidity, the water jet assembly 2 can be installed on the inside of the crushing chamber 8.

[0074] Optionally, there may be multiple water jet components 2, wherein the first water jet component 6 and the second water jet component 7 are water jet components 2 among the multiple water jet components 2.

[0075] The first water jet assembly 6 is located on the first side of the tire rupture area 10, and the second water jet assembly 7 is located on the second side of the tire rupture area 10. The first side and the second side are two opposite sides of the tire rupture area 10.

[0076] In this embodiment of the invention, there are multiple water jet components 2, and the number of first water jet components 6 can be one or more, and the number of second water jet components 7 can be one or more. By individually controlling different water jet components 2, the tire 1 can be crushed by a single water jet 3, or multiple water jet components 2 can be used in combination to crush the tire 1, thereby improving the crushing efficiency of the tire 1.

[0077] In this way, the two sidewalls of tire 1 are respectively opposite to the sides of the tire shredding area 10. Specifically, one sidewall of tire 1 is opposite to the first side of the tire shredding area 10, and the other sidewall of tire 1 is opposite to the second side of the tire shredding area 10. Because the first water jet assembly 6 is located on the first side of the tire shredding area 10 and the second water jet assembly 7 is located on the second side of the tire shredding area 10, water jets 3 are aligned on both sidewalls of tire 1. The first water jet assembly 6 and the second water jet assembly 7 can simultaneously shred both sidewalls of tire 1, thereby improving the shredding efficiency of tire 1.

[0078] It should be understood that at this point, the water-blocking layer 11 still separates the tire breakage area 10 and the water jet assembly 2. Specifically, the water-blocking layer 11 separates the tire breakage area 10 and the first water jet assembly 6, and the water-blocking layer 11 separates the tire breakage area 10 and the second water jet assembly 7. There are various implementation methods. For example, the water-blocking layer 11 includes a first water-blocking layer 11 and a second water-blocking layer 11. The first water-blocking layer 11 separates the tire breakage area 10 and the first water jet assembly 6, and the second water-blocking layer 11 separates the tire breakage area 10 and the second water jet assembly 7. The first water-blocking layer 11 and the second water-blocking layer 11 are planar plate structures, and each has a slot 12 for the water jet nozzle 4 to pass through.

[0079] In a specific implementation, such as Figure 3 As shown, the water-blocking layer 11 includes a first water-blocking surface 13, a second water-blocking surface 14, and a connecting surface 15. One end of the connecting surface 15 is fixedly connected to the first water-blocking surface 13, and the other end of the connecting surface 15 is fixedly connected to the second water-blocking surface 14.

[0080] The first water-blocking surface 13, the second water-blocking surface 14, and the connecting surface 15 cover the upper half of the tire breakage area 10. At this time, the upper half of the tire breakage area 10 is located within the water-blocking layer 11.

[0081] The first water-blocking surface 13 is located on the first side of the first water jet assembly 6 and the tire breaking area 10. The first water-blocking surface 13 is provided with a groove 12, which allows the water jet nozzle 4 of the water jet 3 of the first water jet assembly 6 to pass through, so that the water jet nozzle 4 of the water jet 3 of the first water jet assembly 6 faces the tire breaking area 10 to break one side of the tire 1.

[0082] The second water-blocking surface 14 is located on the second side of the second water jet assembly 7 and the tire shattering area 10. The second water-blocking surface 14 is provided with a groove 12, which allows the water jet nozzle 4 of the water jet 3 of the second water jet assembly 7 to pass through, so that the water jet nozzle 4 of the water jet 3 of the second water jet assembly 7 faces the tire shattering area 10 to shatter the other side of the tire 1.

[0083] The connecting surface 15 is semi-circular and is arranged around the tire breakage area 10. Since the connecting surface 15 is located in the upper half of the tire breakage area 10, the connecting surface 15 can be arranged around the upper half of the tread of the tire 1 located in the tire breakage area 10.

[0084] In this way, the first water-blocking surface 13 and the second water-blocking surface 14 can prevent water and rubber powder from splashing out from the left and right sides of the tire 1, and the connecting surface 15 can prevent water and rubber powder from splashing out from the tread direction of the tire 1. The water and rubber powder generated during the crushing of the tire 1 fall from below the water-blocking layer 11. This arrangement can reduce the splashing of water and rubber powder in the crushing chamber 8.

[0085] In a specific example, there are multiple first waterjet components 6, which are arranged sequentially along a semi-circular trajectory, specifically the upper semi-circular trajectory. Similarly, there are multiple second waterjet components 7, which are also arranged sequentially along a semi-circular trajectory, specifically the upper semi-circular trajectory.

[0086] For example, there are five first waterjet assemblies 6 and five second waterjet assemblies 7. Each waterjet assembly 2 has the same reference datum, and the waterjet 3 of the waterjet assembly 2 can meet the shredding requirements of various tire models 1. In other embodiments, the waterjet assemblies 2 can be combined arbitrarily as needed.

[0087] There are several ways to move the tire 1 into the crushing chamber 8. For example, the crushing chamber 8 is equipped with a door that can be opened and closed. By opening the door, the tire 1 can be placed into the crushing chamber 8 through the door. Then, the door is closed, and the tire 1 is crushed inside the crushing chamber 8.

[0088] In a specific implementation, such as Figure 1 and Figure 2 As shown, the crushing chamber 8 includes an upper chamber 16 and a lower chamber 19. The upper chamber 16 and the lower chamber 19 are detachably connected, with the upper chamber 16 located above the lower chamber 19. The upper chamber 16 and the lower chamber 19 together form a crushing cavity 9, and a water-retaining layer 11 is fixedly connected to the upper chamber 16. Thus, the upper chamber 16 can be lifted using external equipment to separate the upper chamber 16 and the lower chamber 19. Specifically, the connection between the upper chamber 16 and the lower chamber 19 can be such that the end face of the upper chamber 16 and the end face of the lower chamber 19 abut against each other.

[0089] A through hole 20 is provided between the upper chamber 16 and the lower chamber 19, and the through hole 20 penetrates the surface of the crushing chamber 8. For example, in Figure 1 In the example shown, the upper housing 16 has a through hole 20 on its edge facing the lower housing 19. The through hole 20 is a semi-cylindrical structure.

[0090] In this embodiment of the invention, the through hole 20 is used for the passage of a rotating device that supports the inner ring of the tire 1. The rotating device supports the inner ring of the tire 1, thereby allowing the tire 1 to move. Furthermore, the rotating device can drive the tire 1 to rotate.

[0091] In practical use, when the tire 1 needs to be placed into the crushing chamber 8, the upper chamber 16 is lifted by the lifting device, thus separating the upper chamber 16 and the lower chamber 19. At this time, because the water-retaining layer 11 is fixedly connected to the upper chamber 16, the water-retaining layer 11 and the upper chamber 16 are lifted simultaneously. Then, the rotating device supporting the inner ring of the tire 1 moves the tire 1 between the upper chamber 16 and the lower chamber 19. The lifting device moves the upper chamber 16 vertically downward until the upper chamber 16 and the lower chamber 19 are combined. At this time, the rotating device passes through the through hole 20 between the upper chamber 16 and the lower chamber 19, the tire 1 is located in the crushing chamber 8, and the water-retaining layer 11 covers part of the tire crushing area 10. At this time, the water-retaining layer 11 covers the upper half of the tire 1.

[0092] It should be understood that in some embodiments of the present invention, a skin structure 21 may be provided at the through hole 20. The skin structure 21 is a flexible structure. In this way, when the rotating device passes through the through hole 20, the skin structure 21 and the rotating device abut against each other to form a sealing effect, thereby preventing water in the crushing box 8 from leaking out from the gap between the rotating device and the through hole 20. The skin structure 21 is a flexible structure and can fit closely with the rotating device, avoiding collision damage to the rotating device.

[0093] It should be understood that, in the embodiments of the present invention, the various components in the tire shredding equipment can be precisely assembled by improving the processing accuracy.

[0094] Optionally, such as Figure 4 and Figure 5 As shown, the water jet assembly 2 also includes a water jet mounting bracket 5, on which the water jet 3 is mounted. Specifically, both the first water jet assembly 6 and the second water jet assembly 7 described above are provided with water jet mounting brackets 5 for mounting the water jet 3. The water jet mounting bracket 5 can be mounted on the crushing chamber 8.

[0095] In this embodiment of the invention, the upper box 16 includes a front box portion 17 and a rear box portion 18, which are arranged in a horizontal direction. For example, in the horizontal direction, the front box portion 17 is located in front of the rear box portion 18.

[0096] The front box section 17 and the rear box section 18 are movably connected. For example, the front box section 17 and the rear box section 18 are movably connected via a moving mechanism, which allows the front box section 17 and the rear box section 18 to move closer or further apart. Alternatively, the front box section 17 and the rear box section 18 are detachably connected.

[0097] In this embodiment of the invention, the interior of the front box section 17, the rear box section 18, and the lower box 19 forms a crushing inner cavity 9.

[0098] Both the first waterjet assembly 6 and the second waterjet assembly 7 are equipped with waterjet mounting brackets 5. Specifically, the waterjet mounting bracket 5 of the first waterjet assembly 6 is installed inside the front housing section 17, so that the first waterjet assembly 6 is mounted on the front housing section 17. The waterjet mounting bracket 5 of the second waterjet assembly 7 is installed inside the rear housing section 18, so that the second waterjet assembly 7 is mounted on the rear housing section 18. In this way, when the front housing section 17 and the rear housing section 18 are separated, it is convenient for workers to inspect and maintain the first waterjet assembly 6 and the second waterjet assembly 7 through the space between the front housing section 17 and the rear housing section 18.

[0099] Optionally, the tire shredding equipment also includes a frame and a moving mechanism. For example, Figure 1 and Figure 2 As shown, the frame includes an upper frame 22 and a lower frame 23, which are detachably connected. The upper frame 22 is located above the lower frame 23. The upper frame 22 and the lower frame 23 can be connected by the end face of the upper frame 22 abutting against the end face of the lower frame 23, thus facilitating the assembly and disassembly of the upper frame 22 and the lower frame 23.

[0100] In this embodiment of the invention, the front box section 17 and the upper frame 22 are fixedly connected, and the lower box 19 and the lower frame 23 are fixedly connected. A moving mechanism is connected to the upper frame 22 and the rear box section 18, and the moving mechanism controls the rear box section 18 to move away from and towards the upper frame 22. Because the front box section 17 and the upper frame 22 are fixedly connected, the moving mechanism controls the movement of the rear box section 18 and the front box section 17 away from and towards each other.

[0101] In this embodiment of the invention, the overall structure of the tire shredder can be fixed by setting up a frame, while the relative movement of the rear box section 18 and the front box section 17 can be controlled by a moving mechanism. In specific use, when it is necessary to replace the water jet nozzle 4 of the water jet 3 or to perform maintenance operations, the moving mechanism controls the rear box section 18 and the front box section 17 to separate by a preset distance. Then, the operator disconnects the power supply and enters the area between the rear box section 18 and the front box section 17 via a ladder to perform the operation of replacing the water jet nozzle 4 of the water jet 3 or repairing the shredder chamber 8. In some examples, after the moving mechanism controls the rear box section 18 and the front box section 17 to separate by a preset distance, the operation of installing the water jet assembly 2 inside the shredder chamber 8 can be performed. This method makes the installation and removal of the water jet assembly 2 more convenient.

[0102] The moving mechanism can be a cylinder, for example, a target cylinder. The cylinder body of the target cylinder is fixedly connected to the upper frame 22, and the piston rod of the target cylinder is fixedly connected to the rear box section 18. In this way, the relative movement of the rear box section 18 and the front box section 17 can be controlled by moving the piston rod of the target cylinder.

[0103] To guide the relative movement of the rear box section 18 and the front box section 17, slide rails and grooves can be provided on the rear box section 18 and the front box section 17. For example, the side of the rear box section 18 is provided with a slide rail, and the side of the front box section 17 is provided with a groove, which is slidably connected to the slide rail.

[0104] Optionally, the waterjet mounting bracket 5 is used to control the waterjet 3 to move away from and closer to the water barrier layer 11. Thus, when it is necessary to break the sidewall of the tire 1, the waterjet mounting bracket 5 controls the waterjet 3 to move closer to the water barrier layer 11, so that the nozzle 4 of the waterjet 3 passes through the slot 12 of the water barrier layer 11. Then, the nozzle 4 of the waterjet 3 sprays water onto the sidewall of the tire 1 located in the tire breaking area 10 to break the tire 1. When maintenance or other operations are required on the waterjet 3, the waterjet mounting bracket 5 controls the waterjet 3 to move away from the water barrier layer 11, so that there is more space around the waterjet 3, making it easier for workers to operate the waterjet 3.

[0105] Specifically, the water jet mounting bracket 5 includes a motor, a lead screw, and a slider. The output end of the motor is fixedly connected to one end of the lead screw, and the motor can control the rotation of the lead screw. The lead screw passes through the slider, and the external thread of the lead screw is threadedly connected to the internal thread of the through hole 20 of the slider. The water jet 3 is mounted on the slider. In this way, the motor controls the rotation of the lead screw, and driven by the thread, the slider moves along the lead screw. At this time, by changing the rotation direction of the lead screw, the slider can be moved away from or closer to the water-retaining layer 11. Because the water jet 3 is mounted on the slider, the water jet mounting bracket 5 can control the water jet 3 to move away from or closer to the water-retaining layer 11.

[0106] To facilitate the collection of rubber powder obtained from shredded tire 1 and water sprayed from water jet 3, the tire shredding equipment may optionally include a transition trough 24. The transition trough 24 includes a communicating upper port and a lower port, wherein the upper port is fixedly connected to the bottom of the shredding chamber 8 and communicates with the shredding cavity 9. The cross-section of the transition trough 24 gradually decreases from the upper port to the lower port. For example, the transition trough 24 has an inverted trapezoidal structure.

[0107] Thus, the rubber powder obtained from shredding the tire 1 and the water sprayed from the water jet 3 fall to the bottom of the shredding chamber 8 due to gravity, enter the transition trough 24 from the upper port, and flow out from the lower port of the transition trough 24. Because the cross-section of the transition trough 24 gradually decreases from the upper port to the lower port, the rubber powder and water collect at the lower port and flow out of the shredding chamber 8. Inside the shredding chamber 8 or the transition trough 24, the rubber powder and water form a water-rubber mixture. This water-rubber mixture flowing out of the shredding chamber 8 can flow into the screening system through the lower port of the transition trough 24, where the rubber powder can be separated from the water-rubber mixture by a filter screen or other mechanism.

[0108] In other embodiments of the present invention, a water spray nozzle is provided above the transition trough 24 inside the crushing chamber 8. The water spray nozzle can be used to spray water onto the transition trough 24 to rinse the transition trough 24.

[0109] Optionally, such as Figure 1 As shown, the tire shredding equipment also includes an exhaust fan 25. The exhaust fan 25 is located on the outside of the shredding chamber 8, and its exhaust port is connected to the shredding cavity 9. Thus, when shredding the tire 1, a large amount of water vapor is generated inside the shredding chamber 8. After turning on the exhaust fan 25, the water vapor inside the shredding cavity 9 can be drawn out through its exhaust port and collected. This prevents water vapor from spreading inside the shredding chamber 8, thereby reducing the possibility of water vapor leakage from the shredding chamber 8.

[0110] In the tire shredding device of this invention, the shredding box 8 and the water-blocking layer 11 can be made of metal.

[0111] In the tire shredding equipment of this embodiment, the water-blocking layer 11 and the shredding chamber 8 form a double-layer waterproof structure, which can minimize liquid splashing or leakage during the shredding process. The exhaust fan 25 effectively reduces the phenomenon of water vapor spreading inside the shredding chamber 8 during operation. The transition groove 24 facilitates the collection of water and rubber powder inside the shredding chamber 8 for discharge. The moving mechanism connected to the upper frame 22 and the rear chamber section 18 controls the relative movement of the front chamber section 17 and the rear chamber section 18, thereby facilitating the maintenance and upkeep of the water jet 3 and allowing for easy observation of its usage.

[0112] In summary, the tire shredding equipment of this embodiment includes a shredding chamber 8 and a water jet assembly 2. The shredding chamber 8 includes a shredding cavity 9, and the water jet assembly 2 is installed within the shredding cavity 9. The water jet assembly 2 includes a water jet 3. The shredding cavity 9 includes a tire shredding area 10, which is used to house a tire 1. The water jet 3 is located on the side of the tire shredding area 10, opposite to the tire sidewall of the tire 1. The water jet 3 sprays water through its nozzles 4 onto the tire sidewall of the tire 1 located in the tire shredding area 10 to shred the tire 1. When shredding the tire 1, because the tire 1 is housed within the tire shredding area 10, and the water jet 3 is located on the side of the tire shredding area 10, the water jet 3 can approach the tire sidewall, allowing the nozzles 4 of the water jet 3 to effectively impact the tire sidewall, thus efficiently shredding the tire sidewall. The tire 1 is crushed within the crushing chamber 9 of the crushing box 8, which prevents water and rubber powder from splashing out during the crushing process, thus facilitating the crushing operation. This allows for efficient crushing of the tire sidewall.
