Description

Technical Field

[0001] The utility model relates to the technical field of waste tire recycling equipment, in particular to a waste tire ultra-high pressure water cutting equipment. Background Art

[0002] With the rapid development of society, the number of cars in my country has increased rapidly, and the number of waste tires generated each year has also increased. The accumulation of a large number of waste tires not only occupies land, but also pollutes the environment and harms the health of residents. Therefore, the treatment of waste tires has become a very urgent environmental and social problem.

[0003] At present, there are four ways to dispose of waste tires: landfill, incineration, biodegradation, and recycling. From the perspective of environmental protection and energy conservation, crushing and recycling waste tires is the most ideal method. The existing steps of waste tire crushing are to first remove the tire beads on both sides, then cut the annular tire crown into tire strips, and then put the tire strips into a crushing device to crush them into rubber particles.

[0004] However, the crushing devices in the prior art generally have the following technical problems:

[0005] 1. The existing crushing device will shred the steel cord and rubber in the tire strips together when recycling tires, and then separate them from the rubber particles after crushing. During the separation process, the steel wire needs to be vibrated to contact the magnetic screening device. The screening process is lengthy and a large amount of dust will float in the air, affecting the surrounding environment.

[0006] 2. Mechanical crushing has low efficiency and high energy consumption. In addition, during the crushing process, the heat generated by the friction of rubber in the device can easily cause the rubber to stick together, affecting the output of rubber particles and the life of the device.

[0007] 3. Existing devices that can realize continuous crushing and recycling of waste tires are usually complex in structure, large in size, and have high production costs. Utility Model Content

[0008] In order to solve the problems existing in the prior art, the utility model provides an ultra-high pressure water cutting device for waste tires, which can crush the rubber and separate the steel wire at the same time, thereby reducing energy consumption and production costs and increasing the output of rubber particles.

[0009] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is as follows: a waste tire ultra-high pressure water cutting device, comprising a protection cabin, an inlet and an outlet are respectively arranged at both ends of the protection cabin, a frame is installed on the inner wall of the lower end of the protection cabin, a feeding mechanism for transporting tire strips from one end of the inlet to one end of the outlet is installed on the frame, and a water cutting device extending into the protection cabin is installed on the protection cabin;

[0010] Two transverse plates are installed on the frame, and the feeding mechanism includes at least five roller groups, which are rotatably installed between the two transverse plates. The at least five roller groups are equidistantly arranged along the length direction of the protective cabin, and the roller group includes an upper roller shaft and a lower roller shaft. A first motor driving the upper roller shaft to rotate and a second motor driving the lower roller shaft to rotate are installed on the frame, and the first motor and the second motor have opposite directions and the same rotation speed;

[0011] A grid plate is installed between two adjacent lower roller shafts, and the two ends of the grid plate are respectively fixed on the two horizontal plates. The water cutting device includes a plurality of high-pressure water jets, and the high-pressure water jets are located between two adjacent roller groups. The upper roller shaft and the lower roller shaft can clamp the tire strip and transport it to the outlet. The tire strip moved to the grid plate is crushed by the high-pressure water jet to break the rubber wrapped in the steel cord. The frame is provided with a discharge port for the crushed rubber to fall, and the discharge port is located below the feeding mechanism.

[0012] Preferably, the nozzles of the high-pressure water jets are all directed toward the grille plate, the high-pressure water jets close to the outlet are located below the grille plate, and at least three high-pressure water jets away from the outlet are located above the grille plate.

[0013] Preferably, the height of the upper end surface of the grid plate is the same as the height of the upper end surface of the lower roller shaft.

[0014] Preferably, both side edges of the grid plate are provided with guide edges inclined downward along the direction of the adjacent lower roller axis.

[0015] Preferably, the length of the feed opening is greater than the length of the feeding mechanism, and the width of the feed opening is greater than the length of the grid plate.

[0016] Preferably, the outer surfaces of the upper roller shaft and the lower roller shaft are both provided with a plurality of roller teeth evenly distributed circumferentially.

[0017] Preferably, a hopper is installed at the lower end of the discharge port.

[0018] Preferably, a feeding block is installed at one end of the transverse plate close to the inlet, and an upper end of the feeding block is provided with a slope inclined upward along the direction of the upper roller axis.

[0019] Preferably, a discharge plate is installed at one end of the frame close to the outlet.

[0020] The beneficial effects of the utility model are as follows:

[0021] 1. The utility model arranges a high-pressure water jet between two adjacent roller groups. When the tire strip is transported between the two roller groups, the high-pressure water jet will crush the rubber wrapped on its surface without breaking the steel cord inside. The crushing process will not cause the rubber to adhere due to a large amount of heat, thus affecting the yield and quality of the rubber particles. In addition, compared with mechanical crushing, the high-pressure water jet consumes less energy and will not generate a large amount of dust to affect the surrounding environment.

[0022] 2. The utility model sets a discharge port below the transport mechanism on the frame, and installs a discharge plate at one end of the frame near the outlet. The rubber washed down by the high-pressure water jet during transportation will fall to the discharge port, and the steel cord that is not broken by the high-pressure water jet will be gradually transported to the outlet by the roller group. After being impacted by multiple high-pressure water jets, the steel cord completely separated from the rubber slides out from the discharge plate. The two processes of rubber crushing and steel wire separation can be carried out simultaneously, which greatly improves production efficiency.

[0023] 3. The utility model sets a grid plate between two adjacent lower roller shafts. When the tire strip is transported between the two roller groups, the end portion will sag due to gravity. The grid plate can play a certain limiting role, so that the end portion of the tire strip can be smoothly clamped by the next roller group. In addition, when the high-pressure water jet above it crushes the rubber, the grid plate can also play a certain supporting role, and the rubber that is flushed down can also fall from its grid.

DETAILED DESCRIPTION

[0027] In order to facilitate understanding by those skilled in the art, the present invention is further described below in conjunction with the accompanying drawings.

[0028] like Figure 1-2The waste tire ultra-high pressure water jet cutting equipment shown in the figure comprises a protective cabin 1, with an inlet 8 and an outlet 15 respectively arranged at both ends of the protective cabin 1, a frame 13 is installed on the inner wall of the lower end of the protective cabin 1, and a feeding mechanism is installed on the frame 13. One end of the tire strip is put in from the inlet 8, and then the tire strip is transported from the inlet 8 to the outlet 15 by the feeding mechanism, and a water jet cutting device 3 extending into the protective cabin 1 is installed on the protective cabin 1, and the water jet cutting device 3 can break the rubber on the tire strip during transportation;

[0029] Two horizontal plates 5 are installed on the frame 13 of the utility model, and the feeding mechanism includes at least five roller groups 17, which are rotatably installed between the two horizontal plates 5, and at least five roller groups 17 are arranged equidistantly along the length direction of the protective cabin 1, and the roller group 17 includes an upper roller shaft 6 and a lower roller shaft 7, and the lower roller shaft 7 is located directly below the upper roller shaft 6. A first motor 2 that drives the upper roller shaft 6 to rotate and a second motor 16 that drives the lower roller shaft 7 to rotate are installed on the frame 13. The first motor 2 and the second motor 16 have opposite directions but the same rotation speed;

[0030] Specifically, the outer surfaces of the upper roller 6 and the lower roller 7 are uniformly distributed with a plurality of roller teeth in the circumferential direction. A feed block 9 is installed at one end of the transverse plate 5 close to the inlet 8. The upper end of the feed block 9 is provided with a slope surface inclined upward along the direction of the upper roller 6. One end of the tire strip is inserted along the slope surface between the upper roller 6 and the lower roller 7 closest to the inlet 8. The upper roller 6 and the lower roller 7 rotate in opposite directions, and the tire strip is clamped by the roller teeth and pushed toward the outlet 15.

[0031] Specifically, a grid plate 12 is installed between adjacent lower roller shafts 7, and both ends of the grid plate 12 are respectively fixed on the two cross plates 5. The height of the upper end surface of the grid plate 12 is the same as the height of the upper end surface of the lower roller shaft 7. When the tire strip is transported between the two roller groups 17, its end will sag due to gravity. At this time, the grid plate 12 can play a certain limiting role, so that the end of the tire strip can be smoothly clamped by the next roller group 17.

[0032] The water cutting device 3 of the utility model comprises a plurality of high-pressure water jets 4, which are located between two adjacent roller groups 17, and the nozzles of the high-pressure water jets 4 are all directed toward the grid plate 12, and both sides of the grid plate 12 are provided with guide edges inclined downward along the direction of the adjacent lower roller shaft 7. The water sprayed by the high-pressure water jets 4 and the crushed rubber particles can fall from the mesh or guide edges of the grid plate 12;

[0033] Specifically, at least three high-pressure water jets 4 away from the outlet 15 are located above the grid plate 12. Since the upper layer of rubber wrapped with the steel cord on the tire crown is usually thicker than the lower layer, installing multiple high-pressure water jets 4 above the grid plate 12 can achieve a better rubber crushing effect. In addition, when the high-pressure water jet 4 crushes the rubber, the grid plate 12 can play a certain supporting role on the crown.

[0034] Specifically, a high-pressure water jet 4 near the outlet 15 is located below the grid plate 12. The mesh holes on the grid plate 12 enable the jet of the high-pressure water jet 4 below to act smoothly on the tire strip, so that before the tire strip is conveyed to the outlet 15 by the roller group 17, the lower end surface can directly contact the jet of the high-pressure water jet 4, thereby preventing part of the rubber under the steel cord from not completely falling off the steel cord when passing through the first few high-pressure water jets 4.

[0035] The utility model is provided with a feeding port 10 for the crushed rubber to fall on the frame 13, the feeding port 10 is located below the feeding mechanism, the length of the feeding port 10 is greater than the length of the feeding mechanism, the width of the feeding port 10 is greater than the length of the grid plate 12, a hopper 11 is installed at the lower end of the feeding port 10, and a discharge plate 14 is installed at one end of the frame 13 close to the outlet 15, and a collecting bucket can be placed below the hopper 11 and the discharge plate 14 to collect rubber particles or steel cords.

[0036] Specifically, in the process of the upper roller 6 and the lower roller 7 clamping the wheel and transporting it to the outlet 15, the rubber particles crushed by the high-pressure water jet 4 are separated from the steel cord and fall from the discharge port 10, and the whole steel cord that is not crushed by the high-pressure water jet 4 is gradually transported to the outlet 15 by the roller group 17 and slides out from the discharge plate 14. The two processes of rubber crushing and steel wire separation can be carried out simultaneously, which greatly improves the production efficiency.

[0037] It should be understood that the purpose of these embodiments is only to illustrate the utility model and is not intended to limit the protection scope of the utility model. In addition, it should also be understood that after reading the technical content of the utility model, those skilled in the art can make various changes, modifications and / or variations to the utility model, and all of these equivalent forms also fall within the protection scope defined by the claims attached to this application.
