Description

Technical Field

[0001] This invention relates to the field of waste rubber crushing and conveying technology, specifically to a lyocell fiber waste rubber crushing device and system. Background Technology

[0002] The production of lyocell fiber dopes generates waste rubber, and in the field of industrial solid waste treatment, the recycling of waste rubber has become a core link in resource circulation. With the surge in global consumption of rubber products, a large amount of waste tires, industrial rubber waste, and household rubber waste are generated every year. If this waste rubber is directly landfilled without treatment, it will not only occupy land resources but also release harmful substances that pollute the soil and groundwater. Incineration may produce toxic gases such as dioxins, exacerbating air pollution.

[0003] Traditional waste rubber processing relies on manual sorting and mechanical crushing, which is inefficient and poses safety hazards. For example, operators are susceptible to injury from high-speed rotating blades, and manual sorting cannot ensure the purity of the waste rubber, affecting the quality of subsequent recycling. Existing crushing equipment often uses single mechanical forces, such as shearing or extrusion. However, when dealing with tough rubber materials, this easily leads to severe blade wear, increased energy consumption, and uneven particle size, failing to meet the fineness and uniformity requirements of high-end recycled rubber production. Furthermore, the conveying process often causes environmental pollution due to dust and noise, while manual operation increases labor intensity and the risk of human error, hindering large-scale application.

Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0019] Please see Figures 1 to 6This invention provides a technical solution: an automatic waste rubber crushing and conveying device, comprising: a crusher 1, a chain conveyor 2, a buffer tank 3, and an auger pump 6. One end of the chain conveyor 2 is located below the discharge port of the crusher 1, and the other end is located above the port of the buffer tank 3. The outer end of the auger pump 6 is rotatably connected to a bracket 9. The auger pump 6 is inclinedly positioned between the buffer tank 3 and the granulator housing 17 via the bracket 9. One end of the auger pump 6 is located at the lower end of the buffer tank 3, and the lower side of the other end is provided with the granulator housing 17. An output pipe 4 is fixedly installed at the lower end of the buffer tank 3, and a valve 5 is fixedly installed on the output pipe 4. An inlet is fixedly installed on the upper side of one end of the auger pump 6. 7. A discharge port 8 is fixedly installed on the lower side of the other end. The lower end of the output pipe 4 is located above the feed port 7 of the auger pump 6. The discharge port 8 of the auger pump 6 is located at the upper end of the granulator shell 17. A discharge pipe 18 is fixedly installed at the lower end of the granulator shell 17. A waste rubber soaking tank is set at the lower end of the discharge pipe 18. During the production of Lyocell fiber dope, the rubber material from the front reaction vessel flows out through the waste rubber pipe and falls into the crusher 1 in the form of thin strips. At the same time, the water spray head in the crusher 1 sprays water onto the waste rubber strips. The crusher 1 crushes the waste rubber strips into small pieces less than 30mm. After that, the pieces fall onto the chain conveyor 2 through the discharge port and are sent into the waste rubber buffer tank 3 by the chain conveyor 2. The mixture of rubber blocks and water is transported into the granulator shell 17 by the auger pump 6 for granulation. Finally, the particle size reaches 6-8mm and falls into the waste rubber soaking tank. The working temperature is about 30-75 degrees Celsius.

[0020] A bracket 9 is rotatably connected to one side of the outer end of the auger pump 6. A roller 10 is rotatably connected to the lower end of the bracket 9, which facilitates the movement of the auger pump 6. A reinforcing plate 11 is fixedly installed at one end of the bracket 9. Two rotating rods 12 are rotatably connected to the reinforcing plate 11 via ear plates. Two rotating rods 13 are rotatably connected to the other side of the outer end of the auger pump 6 via ear plates. A circular plate 14 is rotatably connected to the end of each rotating rod 12 away from the reinforcing plate 11. A circular plate 14 is rotatably connected to the end of each rotating rod 13 away from the auger pump 6. Next, two circular plates 14 are fixedly connected. Several limiting holes 15 are evenly opened on the outer side wall of the circular plate 14. Fixing bolts 16 are inserted into the limiting holes 15 on the two circular plates 14. The fixing bolts 16 pass through the side walls of the rotating rod 12 and the rotating rod 2 13 and are threaded with nuts, fixing the rotating rod 12 and the rotating rod 2 13 on the circular plate 14, thereby fixing the auger pump 6. By connecting the fixing bolts 16 to different limiting holes 15, it is easy to adjust the support angle of the auger pump 6, which is suitable for granulators of different heights.

[0021] Inside the granulator housing 17, two rotating drums 23 are rotatably connected via a rotating component. Each rotating drum 23 has a sliding sleeve 25 fitted onto its outer end. Several crushing blades 27 are evenly fixedly installed on the outer end of the sliding sleeve 25. A groove 24 is provided on the outer wall of the rotating drum 23. A slider 26 corresponding to the groove 24 is fixedly installed on the inner end of the sliding sleeve 25. When the sliding sleeve 25 is fitted onto the outer end of the rotating drum 23, the slider 26 slides into the groove 24. At the same time, the sliding sleeve 25 is fixed to the outer end of the rotating drum 23 by bolts. When the crushing blades 27 need to be replaced after long-term use, it is convenient to replace them quickly.

[0022] The rotating components include a slot 19, a gear 20, a shield 21, a bearing 29, and a plate 30. The slot 19 is located on the left and right sides of the front and rear ends of the granulator housing 17.

A bearing 29 is fixedly sleeved on the outer wall of the rotating shaft 28, and the bearing 29 is located inside the slot 19.

[0023] The rotating shaft 28 at one end of the rotating drum 23 extends out of the outer end of the insertion groove 19 and is fixedly installed with the gear 31. Two gears 20 are rotatably connected to the outer wall of one end of the granulator housing 17 through the shaft. The two gears 20 mesh with each other and mesh with the outer wall of the gear 31. When one of the rotating drums 23 rotates inward, it will drive the two rotating drums 23 to rotate inward synchronously with the sliding sleeve 25 and the crushing blade 27.

[0024] A shield 21 is fixedly installed on the outer wall of one end of the granulator housing 17. The shield 21 is located outside the gear 1 20 and gear 2 31, and a cover plate 22 is fixedly installed on the upper end of the shield 21. The cover plate 22 can be fixed with bolts for easy disassembly and assembly. Insertion plates 30 are fixedly installed on the outer walls of both the front and rear ends of the bearing 29. When the bearing 29 is located in the insertion groove 19, the two insertion plates 30 are slidably connected to the inner and outer sides of the insertion groove 19 to limit the bearing 29. The insertion plate 30 on one side of the rotating drum 23 is located at the inner end of the shield 21 and is fixed by the cover plate 22, thereby fixing one end of the rotating drum 23. The insertion plate 30 on the other side of the rotating drum 23 is fixed to the outer end of the granulator shell 17 by bolts, fixing the other end of the rotating drum 23. A motor 32 is fixedly installed on the outer end of the insertion plate 30. The output shaft of the motor 32 is fixedly connected to the rotating shaft 28 through a coupling. The motor 32 plays the role of starting the rotating drum 23 to rotate. When the motor 32 starts, it can drive the two rotating drums 23 to rotate synchronously inward with the crushing blades 27, and crush the waste rubber fragments entering the granulator shell 17 into 6-8mm particles again, and discharge them into the waste rubber soaking tank through the discharge pipe 18 at its lower end.

[0025] An automatic crushing and conveying system for lyocell fiber waste adhesive includes the aforementioned automatic crushing and conveying device for lyocell fiber waste adhesive.

[0026] During operation, in the production of lyocell fiber dope, the rubber material from the front-end reactor flows out through the waste rubber pipe in thin strips and falls into the crusher 1. Simultaneously, water is sprayed onto the waste rubber strips from the water spray nozzles inside the crusher 1. The crusher 1 pulverizes the waste rubber strips into small pieces smaller than 30mm, which then fall through the discharge port onto the chain conveyor 2 and are conveyed into the waste rubber buffer tank 3. The mixture of rubber blocks and water is then conveyed by the auger pump 6 into the granulator shell 17 for granulation, ultimately achieving a particle size of 6-8mm, before falling into the waste rubber soaking tank.
