[0062] This invention provides a tire shredding device for facilitating the shredding of tires.

[0063] 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.

[0064] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0065] Figure 1 This is a front view of the tire shredding device provided in an embodiment of the present invention. Figure 2 The image shows a right view of a tire shredding device provided in an embodiment of the present invention.

[0066] See Figure 1 and Figure 2 The tire shredding device of this invention includes a frame 1, a shredding box 2, a water baffle 3, and a water jet assembly 6.

[0067] Both the water jet assembly 6 and the baffle plate 3 are located inside the crushing chamber 2. The crushing chamber 2 is a box structure with a hollow interior. Both the water jet assembly 6 and the baffle plate 3 are located within the hollow interior of the crushing chamber 2.

[0068] One side of the frame 1 is the target side, and the crushing chamber 2 and the baffle plate 3 are both fixedly connected to the target side of the frame 1. The crushing chamber 2 is provided with an openable door 4 on the side away from the target side, and the door 4 is used to allow tires to enter and exit the crushing chamber 2. In order to crush tires, tires can be placed into the chamber through the door 4.

[0069] The waterjet assembly 6 includes a waterjet mounting bracket 61 and a waterjet 62, with the waterjet 62 mounted on the waterjet mounting bracket 61. The waterjet mounting bracket 61 is used to mount the waterjet 62, which is used to spray water to shred tires.

[0070] Inside the crushing chamber 2, a tire crushing area 7 is provided on one side of the baffle plate 3. The tire crushing area 7 is used to accommodate tires. In other words, the tire crushing area 7 is a spatial area used to accommodate tires to be crushed.

[0071] A baffle plate 3 is located between the water jet assembly 6 and the tire rupture zone 7. The baffle plate 3 separates the water jet assembly 6 and the tire rupture zone 7, thereby separating the water jet assembly 6 and the tire located on the tire rupture zone 7. The baffle plate 3 has a slot 5 that passes through it. The slot 5 is used for the water jet nozzle 63 of the water jet 62 to pass through, so that the water jet nozzle 63 faces the tire rupture zone 7.

[0072] In this embodiment of the invention, the water jet 62 is used to spray water onto the tire located in the tire shattering area 7 through the spray nozzle 63 to shatter the tire. Specifically, inside the shattering chamber 2, the spray nozzle 63 of the water jet 62 passes through the slot 5 of the baffle plate 3, and the spray nozzle 63 faces the tire shattering area 7. The spray nozzle 63 of the water jet 62 sprays water onto the tire located in the tire shattering area 7, and the water jet impacts the tire to achieve tire shattering.

[0073] The water jet 62 of this invention operates on the following principle: the nozzle 63 of the water jet 62 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. By adjusting the water pressure, the cutting energy of the water stream can be directed to break only the rubber on the tire, turning it into fine rubber powder, without damaging the steel wires inside the tire. This process cuts the rubber portion of the tire into rubber powder by the water jet, while the tire's steel wires are preserved intact. Thus, the tire's rubber and steel wires are separated at high speed with minimal energy, and the separated rubber directly generates recyclable industrial rubber powder, which is of great economic value.

[0074] Inside the crushing chamber 2, because the tire crushing area 7 is located on one side of the baffle 3, the baffle 3 can prevent water and tire dust from splashing out when water impacts the tire. Furthermore, the tire crushing process is completed within the crushing chamber 2, which has a box-like structure. The crushing chamber 2 prevents water and tire dust from splashing out and reduces noise generated during tire crushing, thus facilitating the tire crushing operation.

[0075] It should be understood that the tires in the embodiments of the present invention can be made of rubber.

[0076] It should be understood that the tires in this embodiment of the invention can be waste tires. The tire shredding device in this embodiment of the invention facilitates the recycling of waste tires.

[0077] It should be understood that the tire shredding device of this embodiment of the invention can shred the tire tread. At this time, when the water jet nozzle 63 of the water jet 62 passes through the slot 5, the water jet nozzle 63 is directed toward the tire tread, so that the water jet from the water jet nozzle 63 of the water jet 62 impacts and shreds the tire tread.

[0078] For example, such as Figure 1 and Figure 3 As shown, the baffle plate 3 has an arc-shaped structure, with its concave surface facing the tire shredding area 7 and the tire tread. At this time, after the water jet nozzle 63 of the water jet 62 passes through the slot 5 on the baffle plate 3, the nozzle 63 of the water jet 62 faces the tire tread. Therefore, the water jet 62 is also used to spray water onto the tire tread located in the tire shredding area 7 through the nozzle 63 to shred the tire tread. Thus, the tire shredding device of this embodiment can be used to shred the tire tread.

[0079] Optionally, such as Figure 2 As shown, the frame 1 includes a connecting mechanism 11, a front frame 12, and a rear frame 13. The target side is located on the front frame 12. That is, both the crushing chamber 2 and the baffle plate 3 are fixedly connected to the front frame 12.

[0080] The rear frame 13 is located on the side opposite to the target side of the front frame 12. At this time, the front frame 12 is located between the crushing box 2 and the rear frame 13.

[0081] Both the front frame 12 and the rear frame 13 are connected to the connecting mechanism 11, and the front frame 12 and the rear frame 13 are movably connected through the connecting mechanism 11. The front frame 12 has a through hole, one opening of which faces the interior of the crushing chamber 2, and the rear frame 13 covers the other opening of the through hole. This through hole extends through the target side. Thus, the structure inside the crushing chamber 2 can be processed through this through hole, such as for inspection and replacement of parts. Specifically, when crushing a tire inside the crushing chamber 2, the rear frame 13 covers the other opening of the through hole, sealing the cavity of the crushing chamber 2 and preventing moisture from escaping through the through hole. When it is necessary to repair the structure inside the crushing chamber 2, such as replacing the water jet 62, because the front frame 12 and the rear frame 13 are movably connected through the connecting mechanism 11, the front frame 12 and the rear frame 13 can be separated through the connecting mechanism 11 to expose the through hole on the front frame 12, allowing workers to process the structure inside the crushing chamber 2 through this through hole. Because the crushing chamber 2 has an openable door 4 on the side away from the target, the internal structure of the crushing chamber 2 can be processed through the through hole penetrating the target side, bypassing the influence of the door 4 and other structures on the workers. The connection mechanism 11, the front frame 12 and the rear frame 13 facilitate the maintenance and repair of the water jet 62, and allow for observation of the water jet 62's usage status at any time.

[0082] For example, when the blade needs to be replaced or repaired, the front frame 12 and the rear frame 13 can be moved a certain distance apart via the connecting mechanism 11. Then, the power can be disconnected, and workers can enter between the front frame 12 and the rear frame 13 via a ladder to replace the blade of the water jet 62 or perform maintenance on the tire shredder through the through-hole on the front frame 12. Furthermore, moving the front frame 12 and the rear frame 13 a certain distance apart via the connecting mechanism 11 also makes the disassembly of the water jet assembly 6 relatively convenient.

[0083] In the embodiments of the present invention, the connecting mechanism 11 can be implemented in various ways, for example, the connecting mechanism 11 is a cylinder or a hinge.

[0084] In a specific example, such as Figure 2 As shown, the connecting mechanism 11 includes a first connecting component, a second connecting component, and a cylinder.

[0085] The first connecting component and the second connecting component are slidably connected along the target direction. The first connecting component is fixedly connected to the front frame 12, and the second connecting component is fixedly connected to the rear frame 13. Thus, the front frame 12 and the rear frame 13 are movably connected due to the sliding connection of the first and second connecting components. The front frame 12 and the rear frame 13 can move relative to each other in the target direction.

[0086] The cylinder body and piston rod are connected to the front frame 12 and the rear frame 13, respectively. For example, the cylinder body is connected to the front frame 12 and the piston rod is connected to the rear frame 13; or, the piston rod is connected to the front frame 12 and the cylinder body is connected to the rear frame 13.

[0087] The piston rod of the cylinder extends and retracts in the same direction as the target direction. In this way, the cylinder can assist the front frame 12 and the rear frame 13 to move relative to each other in the target direction.

[0088] The first connecting component and the second connecting component are, for example, a guide rail and a guide groove, respectively. For example, a guide rail is provided on the front frame 12 and a guide groove is provided on the rear frame 13, and the guide rail is slidably connected on the guide groove.

[0089] It should be understood that the first connecting component and the second connecting component can also be implemented as telescopic pipes or the like.

[0090] The door 4 of this invention can be implemented in various ways, such as a door panel that is hinged to the side wall of the crushing box 2.

[0091] In a specific example, such as Figure 1 As shown, the door 4 includes a first opening / closing door 41, a second opening / closing door 42, a first opening / closing mechanism 43, and a second opening / closing mechanism 44. The first opening / closing mechanism 43 is connected to the first opening / closing door 41 and the side wall of the crushing chamber 2, thus, the first opening / closing door 41 is connected to the side wall of the crushing chamber 2 through the first opening / closing mechanism 43. The second opening / closing mechanism 44 is connected to the second opening / closing door 42 and the side wall of the crushing chamber 2, thus, the second opening / closing door 42 is connected to the side wall of the crushing chamber 2 through the second opening / closing mechanism 44.

[0092] The first opening and closing mechanism 43 and the second opening and closing mechanism 44 are used to control the relative movement of the first opening and closing door 41 and the second opening and closing door 42, so as to realize the opening and closing of the first opening and closing door 41 and the second opening and closing door 42.

[0093] A first channel groove 45 is provided on the side of the first opening door 41 near the second opening door 42, and a second channel groove 46 is provided on the side of the second opening door 42 near the first opening door 41. The first channel groove 45 and the second channel groove 46, when combined, allow a rotating device supporting the inner ring of the tire to pass through. The rotating device extends the tire into the crushing chamber 2 through the combined first channel groove 45 and second channel groove 46, preventing water from flowing out of the crushing chamber 2.

[0094] When a tire needs to be placed in the tire crushing area 7, the first opening and closing mechanism 43 and the second opening and closing mechanism 44 control the first opening and closing door 41 and the second opening and closing door 42 to separate, opening the first opening and closing door 41 and the second opening and closing door 42. The rotating device supporting the inner ring of the tire moves the tire into the crushing chamber 2. Then, the first opening and closing mechanism 43 and the second opening and closing mechanism 44 control the first opening and closing door 41 and the second opening and closing door 42 to move closer together, closing the first opening and closing door 41 and the second opening and closing door 42. The first channel groove 45 and the second channel groove 46 merge, and the rotating device supporting the inner ring of the tire passes through the channel formed by the first channel groove 45 and the second channel groove 46. In this way, the perforated area of ​​the side wall of the crushing chamber 2 can be reduced, thereby reducing the leakage of water vapor when crushing the tire in the crushing chamber 2.

[0095] Optionally, in some embodiments of the present invention, the first opening door 41 and the second opening door 42 can be covered by a flexible skin structure, and the main body of the crushing chamber 2 is a frame structure. This frame structure ensures the rigidity of the water jet assembly 6 mounting base. After the first opening door 41 and the second opening door 42 are covered by the flexible skin structure, the crushing chamber 2 can ensure that the water jet 62 operates in a sealed environment, the liquid inside the crushing chamber 2 does not splash around, and the crushing chamber 2 is easy to clean.

[0096] In an embodiment of the present invention, optionally, the tire located in the tire breaking area 7 can be supported by a rotating device, specifically, one end of the rotating device supports the inner ring of the tire. When the water jet 62 breaks the tire, the rotating device rotates the tire, so that the entire tire is gradually broken by the water jet 62.

[0097] In this embodiment of the invention, the water jet assembly 6 is used to shred tires. The water jet assembly 6 will now be described in detail.

[0098] Optionally, the water jet mounting bracket 61 is fixedly connected to the crushing chamber 2 or the baffle plate 3. The water jet mounting bracket 61 is used to control the water jet 62 to move closer to and further away from the baffle plate 3.

[0099] For example, such as Figure 1 , Figure 3 and Figure 4 As shown, inside the crushing chamber 2, the water jet mounting bracket 61 and the baffle plate 3 are fixedly connected. The water jet mounting bracket 61 can control the water jet 62 to move closer to the baffle plate 3, so that the nozzle 63 of the water jet 62 passes through the slot 5 of the baffle plate 3, and the nozzle 63 is directed towards the tire crushing area 7, thereby preparing for tire crushing. The water jet mounting bracket 61 can also control the water jet 62 to move away from the baffle plate 3, so that the nozzle 63 of the water jet 62 is away from the slot 5 of the baffle plate 3, thereby facilitating operations such as replacing the water jet 62.

[0100] There are various ways to implement the water jet mounting bracket 61, such as a linear module or cylinder structure.

[0101] In a specific example, the water jet mounting bracket 61 includes a mounting body, a first motor, a second motor, a lead screw, and a slider. The first motor, second motor, lead screw, and slider are mounted on the mounting body. The lead screw and slider are threadedly connected; specifically, the lead screw passes through a through hole in the slider, and its outer surface has external threads. The through hole in the slider has internal threads, and the external threads of the lead screw and the internal threads of the slider are threadedly connected. When the lead screw rotates, it drives the slider to move along the lead screw, moving towards and away from the baffle plate 3. The drive shaft of the first motor is fixedly connected to one end of the lead screw. The drive shaft of the first motor drives the lead screw to rotate, thereby controlling the slider's movement towards and away from the baffle plate 3.

[0102] The second motor and the slider are fixedly connected, and the drive shaft of the second motor is driven by the water jet 62, controlling its rotation. Specifically, the water jet 62 is mounted on the drive shaft of the second motor, and the two are fixedly connected. This allows the water jet 62 to move with the slider, enabling the water jet mounting bracket 61 to control its movement towards and away from the baffle plate 3. The drive shaft of the second motor controls the rotation of the water jet 62, allowing its nozzle 63 to rotate. For example, when the nozzle 63 passes through the slot 5 of the baffle plate 3, it can rotate relative to the vertical direction by -15 degrees to 15 degrees under the drive of the second motor's drive shaft. This expands the crushing range of the water jet 62.

[0103] Optionally, the water jet mounting bracket 61 is also used to control the longitudinal movement of the water jet 62 along the tire tread. The longitudinal direction is parallel to the tire's central axis. Specifically, the water jet mounting bracket 61 also includes a third motor, a target lead screw, and a target slider mounted on the mounting body. The target lead screw passes through the target slider, and the target lead screw and target slider are threaded together. The first motor and target slider are fixedly connected. The drive shaft of the third motor is fixedly connected to one end of the target lead screw. The drive shaft of the third motor drives the target lead screw to rotate, causing the target slider to move along the target lead screw. This, in turn, causes the target slider to sequentially drive the first motor, the second motor, and the water jet 62, causing the water jet 62 to move along the surface of the baffle plate 3, that is, along the longitudinal direction of the tire to be broken. Thus, the movement trajectory of the water jet 62 has multiple degrees of freedom relative to the tire, thereby enabling the breaking of a large area of ​​the tire tread.

[0104] Optionally, such as Figure 1 As shown, there are multiple water jet components 6 and multiple slots 5. For example, there are five water jet components 6 and five slots 5. The baffle plate 3 has an arc-shaped structure, for example... Figure 1 and Figure 3As shown, the baffle plate 3 has a semi-circular structure. Multiple water jet assemblies 6 are arranged around the baffle plate 3, which facilitates the independent operation of multiple water jet assemblies 6 and improves the tire crushing effect.

[0105] In this embodiment of the invention, each waterjet assembly 6 has the same reference, the stroke of the waterjet 62 of the waterjet assembly 6 meets the requirements of each tire model, and the number of waterjet assemblies 6 can be arbitrarily combined as needed. In addition, the waterjet 62 of each waterjet assembly 6 has two degrees of freedom of adjustment, which can meet the requirements of the tire shredding process.

[0106] Optionally, such as Figure 4 As shown, the slot 5 is sealed by a flexible skin; in other words, the flexible skin covers the slot 5. The flexible skin has slits, which are openings created in the flexible skin. These slits allow the nozzles 63 of the water jet 62 to pass through. Because the slot 5 is sealed by the flexible skin, water flow through the slot 5 is reduced, minimizing water splashing. Furthermore, the flexible skin's flexible structure prevents damage to the water jet 62 due to impact.

[0107] Optionally, such as Figure 1 As shown, the tire shredding device also includes a transition trough 8, which is located at the bottom of the shredding chamber 2. The transition trough 8 includes an upper port and a lower port, with the upper port communicating with the bottom of the shredding chamber 2. The cross-section of the transition trough 8 gradually decreases from the upper port to the lower port, thus forming a funnel shape to facilitate the collection of water and rubber powder falling from the shredding chamber 2. This water and rubber powder can then flow out of the tire shredding device from the lower port of the transition trough 8. Optionally, the lower port of the transition trough 8 can be connected to a filter device.

[0108] In this embodiment of the invention, within the crushing chamber 2 of the tire crushing device, a water jet 62 sprays water through a spray nozzle 63 onto the tire located in the tire crushing area 7 to crush the tire and obtain rubber powder. Because a transition trough 8 is located at the bottom of the crushing chamber 2, the rubber powder and water fall into the transition trough 8 and flow out of the crushing chamber 2 through the lower port of the transition trough 8, for example, into a screening system. This screening system can screen the mixture of rubber powder and water to obtain rubber powder.

[0109] In some specific examples, the tire shredding device also includes a water nozzle positioned above the upper port of the transition trough 8. The water nozzle is connected to a water pipe. This water nozzle is used to spray water into the transition trough 8. This effectively washes away the mixture of water and rubber powder from the transition trough 8.

[0110] For example, such as Figure 1As shown, the transition trough 8 is designed with an inverted trapezoidal structure to facilitate easy connection of the lower port of the transition trough 8 to the filter screen of the filtration system. A water nozzle connected to the water pipe is located above the upper port of the transition trough 8, and the water pipe can pass through the crushing chamber 2. The water nozzle's flow can be automatically controlled by a computer. When needed, the water nozzle is turned on to flush the transition trough 8, preventing the accumulation of adhesive powder in the transition trough 8.

[0111] Optionally, to reduce the possibility of moisture leakage from the crushing chamber 2, such as Figure 1 As shown, the tire shredding device also includes an exhaust fan 9, which is positioned above the shredding chamber 2. The exhaust port of the exhaust fan 9 is connected to the inner cavity of the shredding chamber 2. This allows the exhaust fan 9 to be turned on to remove moisture generated during tire shredding by water flow, reducing the possibility of moisture leakage from the shredding chamber 2.

[0112] In this embodiment of the invention, the frame 1, crushing chamber 2, baffle plate 3, and water jet assembly 6 are all connected by machined surfaces. Improving machining precision ensures the installation accuracy of each component and guarantees the accurate positioning of the water jet 62. The crushing chamber 2 and baffle plate 3 form a double-layer waterproof structure. The baffle plate 3 allows the water jet nozzle 63 of the water jet 62 to pass through, preventing water splashing, while the crushing chamber 2 prevents water leakage, thus minimizing the occurrence of liquid splashing or leakage during operation. Furthermore, an exhaust fan 9 is installed above the crushing chamber 2 to reduce moisture inside the crushing chamber 2, effectively reducing the occurrence of moisture diffusion during operation. A transition groove 8 is provided at the bottom of the crushing chamber 2 to ensure the collection of rubber powder and water within the crushing chamber 2 and facilitates discharge from the crushing chamber 2. For example, the lower port of the transition groove 8 is connected to a screening system, allowing the rubber powder and water to be discharged into the screening system. The tire shredding device of this invention can increase the airtightness against water, air, noise, etc. During the tire recycling process, the tire shredding device can avoid situations such as water leakage, water vapor leakage, and loud noise.

[0113] In summary, the tire shredding device of this embodiment includes a frame 1, a shredding chamber 2, a baffle plate 3, and a water jet assembly 6. Both the water jet assembly 6 and the baffle plate 3 are located within the shredding chamber 2, and both are fixedly connected to the target side of the frame 1. A closable door 4 is provided on the side of the shredding chamber 2 away from the target side, allowing tires to enter and exit the shredding chamber 2. The water jet assembly 6 includes a water jet mounting bracket 61 and a water jet 62, with the water jet 62 mounted on the water jet mounting bracket 61 to control its position. Inside the shredding chamber 2, a tire shredding area 7 is provided on one side of the baffle plate 3, for accommodating tires. Tires are placed into the shredding chamber 2 through the door 4, placing them within the tire shredding area 7. The baffle plate 3 is located between the water jet assembly 6 and the tire shredding area 7, and has a through-slot 5. The slot 5 allows the nozzle 63 of the water jet 62 to pass through, so that the nozzle 63 is directed towards the tire shredding area 7. The water jet 62 sprays water onto the tire located in the tire shredding area 7 through the nozzle 63 to shred the tire. During tire shredding, within the shredding chamber 2, the nozzle 63 of the water jet 62 passes through the slot 5 of the baffle plate 3, and the nozzle 63 is directed towards the tire shredding area 7. The nozzle 63 of the water jet 62 sprays water onto the tire located in the tire shredding area 7 to shred the tire. Because the tire shredding area 7 is located on one side of the baffle plate 3, the baffle plate 3 can prevent water and tire dust from splashing out. Furthermore, the tire shredding process is completed within the shredding chamber 2, which prevents water and tire dust from splashing out and reduces noise generated during tire shredding, thus facilitating the tire shredding operation.
