Detailed Description
The examples are provided for the purpose of better illustration of the present invention, but are not intended to limit the present invention to the examples. Therefore, those skilled in the art should appreciate that they can readily use the disclosed conception and specific embodiments as a basis for modifying or modifying other embodiments without departing from the scope of the present invention.
Example 1
As shown in fig. 1, the integrated device for separating and molding urethane compounds includes an evaporator 1, and further includes:
an air inlet of the condenser 2 is communicated with an air outlet of the evaporator 1, a liquid outlet is communicated with a feeding funnel 4 through a diversion trench 3, and the diversion trench 3 is provided with a cooling device;
the feed inlet of the scraper heat exchanger 8 is communicated with the feed hopper 4;
specifically, the carbamate compound solution, such as methyl carbamate, has a melting point of 48-50 deg.C, a boiling point of 178 deg.C, ethyl carbamate, a melting point of 48-50 deg.C, a boiling point of 182-184 deg.C, butyl carbamate, a melting point of 53-55 deg.C, a boiling point of 205 deg.C, and a melting point of longer chain carbamate is increased.
The carbamate compound solution synthesized by the urea alcoholysis method can be injected into the evaporator 1 from the feed inlet of the evaporator 1, the evaporator 1 can heat the solution to be higher than the boiling point of carbamate, so that the carbamate compound in the solution is vaporized, and impurities in the solution are intercepted to the evaporator 1 and discharged through the discharge outlet, thereby achieving the purpose of separating and purifying the carbamate compound. The vaporized materials enter the communicated condenser 2 through the air outlet, the gaseous materials exchange heat with the coolant in the condenser 2, the temperature of the materials is reduced to be lower than the boiling point of carbamate compounds, the carbamate compounds are liquefied into liquid, the liquid materials flow out of the liquid outlet of the condenser 2 and fall into the diversion trench 3, and the liquid materials can flow into the feeding funnel 4 along the diversion trench.
In this process, the cooling device can further cool the liquid material, the cooled material is injected into the scraped heat exchanger 8 through the feeding funnel 4, the temperature of the material is further reduced to be lower than the melting point of carbamate in the scraped heat exchanger 8, so that white particles are solidified on the inner wall surface of the scraped heat exchanger 8, and the carbamate compound particles attached to the inner wall can be hung down by the scraper in the scraped heat exchanger 8 and discharged from the discharge port of the scraped heat exchanger 8 to be directly molded into a commercially available product.
In the present embodiment, it is preferable that the evaporator 1 employs a thin film evaporator; the thin film evaporator has high heat transfer efficiency, high evaporation speed and short material retention time, so that the thin film evaporator can better separate substances with larger boiling point difference in carbamate compound solution.
A diffusion cover 5 is arranged at the liquid discharge port, and a cover port of the diffusion cover 5 extends into the flow guide groove 3; because the liquid has relatively high viscosity and cannot flow rapidly, the liquid carbamate compound formed by liquefaction of the condenser can drip into the diversion trench 3 along the edge of the diffusion cover 5, so that the dripping speed of the liquid with high viscosity is reduced, and the liquid in the diversion trench is prevented from splashing;
the cooling device comprises a plurality of cooling fans 6, and all the cooling fans 6 are arranged above the notches of the diversion trench 3; the heat radiation fan 6 can accelerate the air convection in the diversion trench and accelerate the heat exchange between the liquid carbamate compound and the air, thereby reducing the temperature of the liquid carbamate compound.
In this embodiment, it is preferable that the device further includes a spiral pipe conveyor 7, and the feeding port and the discharging port of the spiral pipe conveyor 7 are respectively communicated with the feeding hopper 4 and the feeding port. Because after cooling many times, liquid carbamate class compound viscosity is great after the cooling, for the speed of accelerating liquid carbamate class compound injection scraper heat exchanger 8, can also set up spiral pipe conveyer 7 between feed hopper 4 and scraper heat exchanger 8, spiral pipe conveyer 7's sprue and bin outlet can communicate respectively feed hopper 4 and scraper heat exchanger 8's feed inlet, spiral pipe conveyer 7 can pour into scraper heat exchanger 8 into fast with the higher liquid carbamate class compound of viscosity that feed hopper 4 leaked down, avoids liquid carbamate class compound to solidify in feed hopper.
Example 2
Example 2 is substantially the same as example 1, with the main differences being: as shown in fig. 2, the cooling device includes a plurality of cooling rollers 9, and all the cooling rollers 9 are disposed at the bottom of the diversion trench 3 and abut against the bottom surface of the diversion trench 3.
Specifically, a plurality of cooling rollers 9 may be provided at the bottom of the guide groove 3, and these cooling rollers 9 may be provided in sequence along the flow direction of the liquid in the guide groove 3 and abut against the bottom surface of the guide groove 3.
The water inlet of the cooling roller 9 can be communicated with a water pump 10 through a water supply pipe, cooling water is injected into the cooling roller 9 through the water pump 10, and the water outlet of the cooling roller 9 can be communicated with a circulating water source through a water discharge pipe. Thus, cooling water can be circularly injected into the cooling roller 9. Because the driving motor 11 can drive the cooling roller 9 to rotate through the transmission mechanism, the temperature of the surface contacting with the diversion trench 3 can be kept relatively stable, and the liquid carbamate compound in the diversion trench 3 can be stably cooled.
Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
