Description
Technical field
The utility model relates to the technical field of polymeric kettle, specifically a kind of Novel polymerizing kettle structure, particularly its inside cold cycling structure.
Background technology
Polyurethane polymerization is once dropped in polymeric kettle by polymerization single polymerization monomer, the control overflow of polymerization temperature is strict, reaction temperature height easily produces performance and the stability that gel (super high molecular weight polymer) affects final emulsion, even because temperature control causes " cruelly poly-" to make product rejection; Temperature low reaction is difficult to carry out.Therefore, polymerization requires namely from 28 DEG C, to be warming up to 65 DEG C gradually in 2 hours by heating schedule, is warming up to 70 DEG C 65 DEG C of insulations after 2 hours in 1 hour.Then 70 DEG C of insulations 5 hours.Be polymerized to exothermic reaction, react initial heat release rapidly but along with reaction carry out, the reduction of monomer concentration causes exotherm rate to decline, and adds that the reaction temperature that affects to function of environment heat emission is difficult to control.Reaction is in the past slow, and past still chuck leads to Steam Heating, the logical cold water that reacted fast, and temperature unstable product quality fluctuated also appears " cruelly poly-" accident.
Summary of the invention
The purpose of this utility model is to provide a kind of Novel polymerizing kettle structure, the built-in coil pipe of still chuck of this polymeric kettle, is equipped with the water system of water temp. auto-control simultaneously, and control temperature is 80 DEG C, avoid temperature in the kettle fluctuated, the coefficient of stability of effective control for product quality.
To achieve these goals, the technical solution of the utility model is: a kind of Novel polymerizing kettle structure, the still wall place of described polymeric kettle forms chuck, ring-type coil pipe is provided with in the chuck chamber of this chuck, the water inlet end of ring-type coil pipe is connected with hot water control valve by pipeline, the water inlet end in chuck chamber is connected with cooling sea water regulating valve by pipeline, hot water control valve and cooling sea water regulating valve are all connected with the control end of PLC, temperature sensor is provided with in the cavity of polymeric kettle, this temperature sensor is connected with the data acquisition end of PLC, the water inlet end of ring-type coil pipe and the water inlet end in chuck chamber are all arranged near the position at the bottom of still.
The utility model discloses a kind of Novel polymerizing kettle structure, it sets up ring-type coil pipe in still chuck, possess independently heat circulating system and independently cooling recirculation system, artificial PLC control system is utilized to detect temperature in the kettle, simultaneously, have more the open to shut to regulate detecting data and realize cold valves and hot water valve, finally guarantee that temperature in the kettle is steady in a long-term at 80 DEG C, be conducive to the coefficient of stability controlling product quality.

1, polymeric kettle;
2, chuck;
3, ring-type coil pipe;
4, hot water control valve;
5, cooling sea water regulating valve;
6, the control of PLC.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
The utility model discloses a kind of Novel polymerizing kettle structure, it is different from prior art and is: the still wall place of described polymeric kettle 1 forms chuck 2, ring-type coil pipe 3 is provided with in the chuck chamber of this chuck 2, the gap of 1cm-5cm is formed between ring-type coil pipe 3 outer wall and chuck 2 inwall, the gap of 1cm-6cm is formed between the pipeline of ring-type coil pipe 3, be conducive to realizing cold and hot exchange to greatest extent, the water inlet end of ring-type coil pipe 3 is connected with hot water control valve 4 by pipeline, the water inlet end in chuck chamber is connected with cooling sea water regulating valve 5 by pipeline, hot water control valve 4 and cooling sea water regulating valve 5 are all connected with control 6 end of PLC, temperature sensor is provided with in the cavity of polymeric kettle 1, this temperature sensor is connected with the data acquisition end of PLC, temperature sensor provides 4-20MA signal, corresponding 20-100 DEG C, the water inlet end of ring-type coil pipe 3 and the water inlet end in chuck chamber are all arranged near the position at the bottom of still.
In the specific implementation, still chuck passes into cooling water, and in cooling water flow control valve and still, temperature of charge is chain, and chuck coil pipe passes into 80 DEG C of water that hot water supply system provides, and hot water flow is also chain with temperature in the kettle.At PLC, start automatic control by technological requirement setting still temperature program (temperature-time curve).If temperature is lower than design temperature, hot water control valve starts and improves water temperature (now, cooling sea water regulating valve is in closed condition) in chuck; On the contrary, cooling sea water regulating valve starts to reduce reaction temperature.
The above is only preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, although the utility model discloses as above with preferred embodiment, but and be not used to limit that this is novel, have in any art and usually know the knowledgeable, not departing from the scope of technical solutions of the utility model, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be the content not departing from technical solutions of the utility model, according to any simple modification that technical spirit of the present utility model is done above embodiment, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
