Summary of the invention
For overcoming above technical problem, the invention provides a kind of discharging equipment and discharging technology thereof that is applicable to the high viscosity liquid resin, have the advantages that discharging is fast, cooling is fit to the large-scale production needs soon.
Discharging equipment of the present invention comprises is located at going out stub bar and being located at out the material collecting tank of stub bar below of reactor exit, it is characterized in that this discharging special equipment also comprises:
Be located at out the heater on the stub bar, the temperature when keeping the material discharging is suddenly lowered the temperature when preventing discharging, and material is blocked in the blanking process.
Be located at out the screen cloth of stub bar bottom, be separated into slice after making material by screen cloth, cool off sooner, also be beneficial to pulverizing.For make after the separation the slice adhesion together, the hole of screen cloth can not be too close, according to screen area, the about 0.5-1 of spacing centimetre, the about 0.5-2cm in aperture.
Be located at the grain-cutter of screen cloth below, this grain-cutter at high temperature tentatively is cut into particle with the mucus that flows out, and is convenient to pulverize.Suggestion adopts the fusion grain-cutter of rotation at a high speed further to raise the efficiency.
Be located at the cooling fluid generator of screen cloth below, cooling fluid results from from the below of the mucus of screen cloth outflow, makes high temperature mucus cool off fast in the process that flows downward.This cooling fluid generator can be distilled water or deionized water, also can be the water smoke that is produced by the steam generator, is distributed in the grain-cutter below.
As another kind of technical scheme, described heater is located at out the stub bar inwall, and inwall is provided with the cavity that is full of thermal medium and has the connector that forms the peripheral passage with extraneous thermal medium.
The described thermal medium cavity that goes out the stub bar inwall can be connected to form the peripheral passage with the heating temperature-control system of reactor.
Its process characteristic is, the above-mentioned discharging special equipment of this process using, and comprise the steps:
A, insulation screen cloth discharging step, promptly material is extruded strip-shaped materials by the stub bar that goes out that is provided with heater from the screen cloth that goes out the stub bar lower end;
B, pelletizing step, material is extruded the back by the grain-cutter of being located at described screen cloth lower end from screen cloth, will be cut into grain from the mucus that screen cloth flows out;
C, cooling step, material is extruded the back by the cooling fluid cooling that is distributed in described screen cloth below from screen cloth;
D, material grain are collected step, are collected by the material collecting tank of being located at the grain-cutter below, and this material collecting tank is connected with pulverizer.
Slower as the polymer discharging speed, can exert pressure to the polymer liquid level by the upper end of polymeric kettle.For example, the inert gas pressurization, pressurized with compressed air or mechanical piston pressing mode are pressurizeed.
With respect to prior art, advantage applies of the present invention exists:
1. the science simple in structure of special equipment, technological design is reasonable.
2. adopt this process stream cooling fast, discharging efficient height is when preventing that polymerization product from high temperature reacting
Between long, guarantee product quality.
3. satisfy the needs that large-scale industrialization is produced, enhance productivity energy-saving low-carbon.
