Brief description
Fig. 1 show the waste rubber processing device schematic diagram of the present invention.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.It should be appreciated that it is described herein
Specific embodiment only in order to explain the present invention, be not intended to limit the present invention.
As shown in figure 1, the waste old process dress integrating SCF-CO 2 precursor reactant and microwave heating of the present invention
Put including homogenizer 1, supercritical fluid CO 2 generator 2 is supercritical steam pressure generator or supercritical DC furnace
Generator, with described supercritical fluid CO 2 generator 2 through high-pressure pump 3, such as the first retort of high pressure micro syringe pump connection
4, such as high pressure resistant tank body, and the second retort 6 being arranged on below the first retort and being connected by expects pipe 5, described first
Through feeding mechanism 7, such as rubber powder flexible conveyer connects the discharging opening of the charging aperture of retort and described homogenizer, institute
The first retort stated be internally provided with first material transmission mechanism, such as screw conveying device, on the tank body of the first retort
It is provided with CO2Actuator epithelium, temperature control/display, Stress control/display device and pressure relief device are to ensure reaction
Safety, described actuator epithelium is used for discharging after the completion of reaction supercritical CO2Fluid.The inside of the second described retort
Be provided with second material transmission mechanism, such as screw conveying device, the tank body of the second retort is provided with microwave generation mechanism with
And cooling body, such as jacket type spiral cooling tube, it is provided with discharge conveying mechanism in described expects pipe 5, such as screw conveying device.
The waste rubber processing device collection stirring of the present invention, supercritical CO2Fluid reaction and microwave heating, in one, lead to
Cross material to transmit in each inter-agency utilization screw conveying device, effectively reduce manpower and use, improve working (machining) efficiency, and, lead to
Cross the setting up and down of the first retort and the second retort, improve the convenience that material between transmits, and utilize
The screw conveying device of setting in expects pipe, enables uniformly to convey and lays uniformly it is ensured that entering material after in the second retort, carry
High microwave heating effects, meanwhile, transmit material with screw conveying device in the first retort and the second retort respectively, are passing
