Description

Technical Field

[0001] The invention relates to the technical field of rubber powder plasticization, in particular to an energy-saving and environment-friendly vulcanized rubber powder plasticization processing device. Background Art

[0002] The plasticization process of vulcanized rubber powder refers to the process of converting discarded rubber products into vulcanized rubber powder, and then using a series of special processes, including the addition of auxiliary materials such as activators and softeners, to make the vulcanized rubber powder regain a certain degree of plasticity and good fluidity, so as to facilitate subsequent processing and reuse. In traditional recycled rubber production, the plasticization regeneration of vulcanized rubber powder is often carried out through a desulfurization tank. A key problem of this process is that the desulfurization tank will release a large amount of high-temperature and high-pressure gas during operation. These gases are difficult to collect and treat thoroughly, which brings great pressure to environmental protection management.

[0003] In order to replace the desulfurization tank process, many companies have tried to use atmospheric pressure continuous plasticizers for recycling. Since the heating method of this equipment is to heat the outer wall of the long-distance spiral, the plasticized material is heated unevenly, which affects the quality stability of the recycled rubber. In addition, the continuous plasticizer also needs to invest in additional environmental protection equipment to ensure the effective treatment of exhaust gas, which leads to increased costs.

The surface of the main rod 72 is fixed with a plurality of stirring rods 73. In this embodiment, through the arrangement of the high-speed motor 71, the main rod 72 and the stirring rod 73, under the action of the high-speed motor 71, the main rod 72 drives the stirring rod 73 to rotate, and then the stirring rod 73 stirs the raw material in the inner cavity of the plasticizing machine 1, and the high-speed friction between the stirring rod 73 and the raw material is used to achieve the effect of plasticizing the raw material.

[0023] The auxiliary mechanism 8 includes a driving gear 81 fixed to one end of the main rod 72, the surface of the driving gear 81 is meshed with a driven gear 82, the inner cavity of the driven gear 82 is fixed with a rotating rod 83, the other end of the rotating rod 83 is provided with a transmission timing gauge 84, the other end of the transmission timing gauge 84 is fixed with a driving disk 85, the driving disk 85 rotates on the surface of the main rod 72, and scraper rods 86 are fixed on both sides of the surface of the driving disk 85. In this embodiment, through the arrangement of the driving gear 81, the driven gear 82, the rotating rod 83, the transmission timing gauge 84, the driving disk 85 and the scraper rod 86, when the main rod 72 rotates, the driving gear 81 fixed to one end of the main rod 72 can rotate, so that the driven gear 82 drives the rotating rod 83 and the transmission timing gauge 84 to work, under the action of the transmission timing gauge 84, the driving disk 85 and the scraper rod 86 are rotated, and under the action of the scraper rod 86, the material on the inner cavity wall of the plasticizer 1 can be scratched.

[0024] The scraper rod 86 slides in the inner cavity of the plasticizer 1, and the surface shape of the scraper rod 86 is complementary to the arc surface of the inner cavity of the plasticizer 1. In this embodiment, through this arrangement, the scraper rod 86 is more capable of scraping the material in the inner cavity of the plasticizer 1, thereby improving the practicality of the device.

[0025] The combustion mechanism 9 includes an air outlet 91 connected to the surface of the plasticizing machine 1, the other end of the air outlet 91 is connected to a temperature-controlled combustion chamber 92, the inner cavity of the temperature-controlled combustion chamber 92 is provided with a combustion disk 93, the other end of the temperature-controlled combustion chamber 92 is connected to an air inlet 94, and the surface of the air outlet 91 is connected to an external pipe 95.

[0026] The heat exchange mechanism 10 includes a melting and heat preservation metering bin 101 fixed to the surface of the temperature-controlled combustion chamber 92, the inner cavity of the melting and heat preservation metering bin 101 is connected to an oil suction pipe 104, the other end of the oil suction pipe 104 is connected to a refueling pipe 103, the surface of the refueling pipe 103 is connected to an oil pump 102, the other end of the refueling pipe 103 is connected to the inner cavity of the plasticizer 1, and the external pipe 95 passes through the inner cavity of the melting and heat preservation metering bin 101.

[0028] A motor 5 is fixed to one side of the surface of the isolation cooling chamber 4, and a stirring plate 6 is fixed to the output shaft of the motor 5. The stirring plate 6 rotates in the inner cavity of the isolation cooling chamber 4. In this embodiment, through the arrangement of the motor 5 and the stirring plate 6, when the plasticized high-temperature rubber powder is cooled, in order to avoid large-area contact of the high-temperature rubber powder with the air to cause insufficient plasticization, the material is discharged into the isolation cooling chamber 4 through the discharge port 3, and the rubber powder stays therein for about forty minutes and is discharged after being fully cooled after continuous stirring by the motor 5 and the stirring plate 6.

[0029] It is worth noting that the cooling surplus gas in the isolation cooling chamber 4 can also be sent to the temperature-controlled combustion chamber 92 through a pipeline so that it participates in the combustion and improves resource utilization.

[0030] Working principle: In the production of recycled rubber, the raw materials are input into the feed port 2 through the spiral feeder, and then the raw materials are input into the plasticizing machine 1. Then the staff can use the plasticizing and stirring mechanism 7. Under the action of the high-speed motor 71, the main rod 72 drives the stirring rod 73 to rotate at high speed, so that the stirring rod 73 and the raw materials are stirred at high speed to plasticize the raw materials. In addition, when the main rod 72 rotates, the driving gear 81 fixed on the surface of the main rod 72 can work, and then under the action of the driven gear 82, the rotating rod 83, the transmission timing gauge 84 and the driving disk 85, the scraper rod 86 scrapes the bonding principle of the inner cavity of the plasticizing machine 1 to improve the plasticizing effect. In the plasticizing process of the raw materials, the exhaust gas can enter the temperature-controlled combustion chamber 92 through the air outlet 91, and then on the combustion disk 93 and the air inlet 94, the waste gas is burned and discharged through the external pipe 95 after combustion. In addition, when the waste gas is burned, the residual heat can enter the melting and heat preservation metering bin 101, and then heat and keep the softened oil in the melting and heat preservation metering bin 101, so as to improve the resource utilization rate. During the operation of the plasticizer 1, the softened oil can be sent into the plasticizer 1 under the action of the oil pump 102, the filling pipe 103 and the oil suction pipe 104, so as to improve the practicality of the device. After the plasticization of the raw materials in the plasticizer 1 is completed, the material enters the isolation cooling chamber 4 through the discharge port 3, and the material can be cooled. In order to avoid the high-temperature rubber powder from contacting with the air over a large area and causing insufficient plasticization, the rubber powder stays therein for about 40 minutes and is continuously stirred by the motor 5 and the stirring plate 6 and then fully cooled and discharged.
