Description

Technical Field

[0001] The utility model belongs to the technical field of reclaimed rubber processing, and particularly relates to a horizontal centrifugal drying machine and a granular reclaimed rubber granulation drying system. Background Art

[0002] Recycled rubber is a rubber that has a certain degree of plasticity and can be reused, which is made from the vulcanized scraps in the production of rubber products. In some cases, the recycled rubber needs to be granulated by a granulator. In order to avoid the adhesion of rubber particles in the later stage, the rubber particles need to be cooled in time and the product needs to be isolated. There is water residue on the surface of the rubber particles after isolation. Excessive water content will affect the performance of the rubber particles, reduce the tensile strength and hardness of the recycled rubber, and also affect its environmental performance, because too much water can easily cause the recycled rubber to produce odor and harmful substances, affecting the overall service life and effect of the rubber particles.

[0004] However, the above dryer adopts a vertical drying barrel. When the material to be dried is continuously added into the drying barrel, the newly added wet material is likely to affect the dried material, which is inconvenient to continuously add material for drying, and the drying efficiency is low.

[0026] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the application and with reference to the accompanying drawings.

[0028] The spin drying barrel 1 is provided with a blowing assembly, and the blowing assembly is used to provide hot air to the inner cavity of the spin drying barrel 1;

[0029] The spin-drying tub 1 is provided with a water absorbing component, and the water absorbing component is used to suck the liquid in the inner cavity of the spin-drying tub 1 .

[0030] By tilting the drying barrel 1, the granular rubber material falls into the drying barrel 1 from a higher position of the drying barrel 1. As the drying barrel 1 rotates, the rubber particles slide from the upper end of the drying barrel 1 to the lower end of the drying barrel 1 under the action of gravity and the thrust of the spiral blade 8, and are discharged from the discharge pipe 19. During the movement, the rubber particles are gradually dried by the centrifugal action of the drying barrel 1, the cooperation of the blowing component and the water absorbing component.

[0031] like Figure 1-2 As shown, the blowing assembly includes: a blower 10 and a heating box 11 arranged on the side wall of the spin drying barrel 1, the outlet of the blower 10 is connected to the inlet of the heating box 11, the outlet of the heating box 11 is connected to one end of a connecting pipe 12, the other end of the connecting pipe 12 extends to the inner cavity of the spin drying barrel 1 and is connected to an air outlet plate 13, the air outlet plate 13 is fixedly connected to the connecting pipe 12 through a connecting ring 15, and a plurality of air outlets 14 are opened on the air outlet plate 13.

[0032] Through the cooperation of the blower 10, the heating box 11 and the air outlet plate 13, hot air can be continuously provided to the inside of the spin-drying barrel 1 to improve the drying efficiency of the material; preferably, the air outlet plate 13 is arranged on the side of the spin-drying barrel 1 close to the discharge pipe 19, so that the hot air can act on the inner cavity of the entire spin-drying barrel 1, and the air outlet plate 13 is arranged in an annular manner and is arranged coaxially with the rotating shaft 9, and an avoidance groove is opened at the bottom to avoid the rotating shaft 9. The annular arrangement of the air outlet plate 13 can make the hot air blow evenly to the inner cavity of the spin-drying barrel 1, thereby improving the uniformity of drying the material in the spin-drying barrel 1; preferably, the air outlets 14 are evenly arranged on the air outlet plates 13 to further ensure the uniformity of the air outlet, and the distribution density of the air outlets 14 on the air outlet plates 13 can be determined according to actual needs.

[0033] like Figure 1and Figure 3 As shown, the water absorption assembly includes: a suction device 17 arranged on the side wall of the spin-drying tub 1, the suction device 17 is connected to the inner cavity of the spin-drying tub 1 through a water suction pipe 16, at least one water collecting tank 23 is arranged on the inner cavity side wall of the spin-drying tub 1, the water suction pipe 16 is connected to the lower part of the water collecting tank 23, and the suction device 17 is cooperated with a water collecting box 18.

[0034] Through the cooperation of the suction device 17, the water suction pipe 16 and the water collecting tank 23, the accumulated liquid inside the spin-drying barrel 1 can be sucked out in time. When part of the overly wet material is directly transported to the inner cavity of the spin-drying barrel 1, the excessive accumulated liquid can flow into the water collecting tank 23 and be sucked out in time by the suction device 17, so as to prevent the accumulated liquid from flowing to the discharge pipe 19 and affecting the drying effect of the spin dryer on the material.

[0035] Preferably, the water collecting tank 23 is divided into two sections in the spin drying barrel 1, one section is located in the upper part of the inner cavity of the spin drying barrel 1, and the other section is in the middle and lower part of the inner cavity of the spin drying barrel 1, and the lower ends of the two sections of the water collecting tank 23 are respectively connected to the suction device 17 through the suction pipe 16; through the setting of the segmented water collecting tank 23, it can be further ensured that the accumulated liquid inside the spin drying barrel 1 can be discharged in time, and the suction device 17 can adopt the common suction equipment on the market, which will not be repeated here. The accumulated liquid sucked by the suction device 17 is discharged into the water collecting tank 18, which is convenient for the subsequent recycling or treatment of the accumulated liquid.

Preferably, the outer wall of the material stopper ring 21 is arranged in contact with the inner wall of the spin-drying barrel 1, and the inner part of the axial section is arranged as a trapezoidal cavity, and the material stopper ring 21 is used to prevent the material from accumulating at the angle formed by the inner cavity of the spin-drying barrel 1 and the rear cover 3.

[0038] like Figure 1 As shown, the angle between the spin drying barrel 1 and the horizontal plane is 15°. By setting this angle, when the rotation speed of the spin drying barrel 1 is constant, the drying time of the material inside the spin drying barrel 1 can be controlled to avoid the material staying in the spin drying barrel 1 for too long and affecting the effect of the equipment drying the material, or the material staying in the spin drying barrel 1 for too short a time and affecting the drying effect of the material.

[0039] like Figure 1 As shown, a support base 22 is provided below the spin drying tub 1, and the support base 22 is used to provide support for the spin drying tub 1. Figure 1 As shown, in a specific embodiment, there are two support seats 22, which are respectively matched with the two ends of the outer wall of the spin drying tub 1; preferably, the support seat 22 can adopt a height-adjustable support device, such as a hydraulic lifting support seat or a threaded lifting device, and the lifting device is rotatably connected to the spin drying tub 1, so that the operator can adjust the inclination angle of the spin drying tub 1 during actual use. During the adjustment process, at least one lifting device can move horizontally to avoid interference between the lifting device and the spin drying tub.

[0040] like Figure 1 As shown, the height of the spiral blade 8 is one fifth of the inner diameter of the inner net barrel 6. By setting the spiral blade 8, the sliding speed of the material in the inner cavity of the spin-drying barrel 1 can be controlled; and some agglomerated materials can be broken up. When the agglomerated materials roll in the spin-drying barrel 1, they collide with the spiral blade 8 to break the agglomerated materials; by setting the height of the spiral blade 8, the hot air blown out by the blowing component can be easily flowed in the inner cavity of the spin-drying barrel 1, thereby improving the utilization efficiency of the hot air.

[0041] like Figure 4 As shown, a granulated reclaimed rubber granulation and drying system comprises, according to the processing sequence of the reclaimed rubber, a granulation device 101, an isolation and mixing device 102, the above-mentioned horizontal centrifugal dryer 103, a screening device 104 and a collecting device 105;

[0042] During the production process, the granulation device 101 is used to granulate the refined reclaimed rubber, and the generated rubber particles are transported to the isolation mixing device 102 by water flow. The high-temperature rubber particles just produced can be cooled by water flow to prevent the particles from sticking together; the isolation mixing device 102 is used to mix the rubber particles with the rubber isolation agent. The rubber isolation agent is an organic combination of stearic acid derivatives, special anti-sticking agents, special surfactants, ultrafine powders and other materials to effectively prevent the rubber particles from sticking together. In actual production, the corresponding rubber isolation agent can be selected according to the different products produced; the rubber particles after isolation treatment are transported to the horizontal centrifugal dryer 103 for drying treatment; the rubber particles dried to a suitable water content are transported to the screening device 104 for classification according to different sizes; the classified rubber particles are transported to the collecting device 105 for classification and storage, completing the production drying process of the reclaimed rubber.
