Abstract
The utility model discloses a solvent condensing device for a polyurethane resin reaction kettle, which comprises a condenser communicated with the top of the reaction kettle through a condensing pipeline. The condensing pipeline is provided with a safe recovery device which comprises a U-shaped bent pipe arranged on the condensing pipeline and a transparent visible cup, wherein the transparent visible cup is arranged below and communicated with the U-shaped bent pipe. The safe recovery device is arranged on the condensing pipeline at the top of the polyurethane resin reaction kettle, and condensed water or recirculated water which enters into the condensing pipeline by accident can be discharged from a discharging pipe arranged at the lower portion of the transparent visible cup, thereby preventing water from entering into the reaction kettle to generate production accidents.
Description
Technical field
The utility model relates to a kind of condensing unit, is specifically related to a kind of solvent condenses device that is used on the polyurethane resin reactor.
Background technology
Polyurethane resin is that main chain contains-base polymer of NHCOO-constitutional repeating unit, and english abbreviation is PU.Polyurethane resin is to be polymerized by isocyanates (monomer) and hydroxy compounds, owing to contain the carbamate groups of strong polarity, is insoluble to non-polar group, has good oil resistivity, toughness, wearability, resistance to ag(e)ing and cohesive.The material that adapts to wide temperature range (50～150 ℃) be can make with different material, elastomer, thermoplastic resin and thermosetting resin comprised.Hydrolysis not under the high temperature, also alkali-proof medium not.
Polyurethane elastomer can be used as cylinder, conveyer belt, flexible pipe, auto parts, sole, synthetic leather, electric wire and medical artificial organ etc.; The flexible foam body is used for the liner of vehicle, room, clothes, hard foam is as heat insulation, sound-absorbing, packing, insulation and low foaming synthetic wood, coating is used for senior vehicle, furniture, wood and metal protection, pond dam and building anti-seepage material, and fabric coating etc.Adhesive all has good adhesion strength to metal, glass, pottery, leather, fiber etc.Polyurethane also can be made into emulsion, magnetic material etc. in addition.
In the polymerisation of polyurethane resin, because with the carrying out that reacts, temperature raises gradually, the solvent in the reactor can volatilize because temperature raises.In the prior art, generally be communicated with condenser,, continue to participate in reaction, avoid the loss of solvent the reactor that refluxes back after the solvent condenses that volatilizes on the top of reactor.But in the actual production, tend to take place condensed water or recirculated water and reveal the production accident that enters reactor, influence the material in reactor quality, even can cause whole still material damage, cause big economic loss.
Summary of the invention
Technical problem to be solved in the utility model is: at the deficiency that prior art exists, provide a kind of solvent condenses to reclaim safety, the solvent condenses device on the polyurethane resin reactor of being used for that condensed water or recirculated water enter reactor can not take place.
For solving the problems of the technologies described above, the technical solution of the utility model is:
Be used for the solvent condenses device on the polyurethane resin reactor, comprise the condenser that is communicated with by condenser pipe with the top of reactor, described condenser pipe is provided with safe retracting device.
The transparent handleless cup of looking that described safe retracting device comprises the U type bend pipe that is arranged on the described condenser pipe and is arranged on described U type bend pipe below and is communicated with it.
The described transparent cup bottom of looking is provided with vomit pipe.
Owing to adopted technique scheme, the beneficial effects of the utility model are:
The utility model is provided with safe retracting device on the condenser pipe of the top of polyurethane resin reactor, after condensed water or recirculated water enter condenser pipe accidentally, at condensed water or circulating water flow during through U type bend pipe, enter the transparent handleless cup of looking that is communicated with it, look in the handleless cup transparent, because water is different with the proportion of solvent, therefore can judge whether entered water in the condensed solvent, if entered water accidentally, look the vomit pipe that cup bottom is provided with and emit from transparent immediately, avoid water to enter reactor and cause production accident.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the structural representation of the utility model embodiment.
Among the figure, 1. reactor; 2. condenser; 3. condenser pipe; 4.U type bend pipe; 5. the transparent handleless cup of looking; 6. vomit pipe.
The specific embodiment
As shown in drawings, be used for the solvent condenses device on the polyurethane resin reactor, comprise the condenser 2 that is communicated with by condenser pipe 3 with the top of reactor 1, described condenser pipe 3 is provided with safe retracting device, described safe retracting device comprises the U type bend pipe 4 that is arranged on the described condenser pipe 3, with the transparent handleless cup 5 of looking that is arranged on described U type bend pipe 4 belows and is communicated with it, described transparent handleless cup 5 bottoms of looking are provided with vomit pipe 6.
In the polyurethane resin course of reaction, after if condensed water or recirculated water enter condenser pipe 3 accidentally, at condensed water or circulating water flow during through U type bend pipe 4, enter the transparent handleless cup 5 of looking that is communicated with it, transparent look the handleless cup in 5, different according to water with the proportion of solvent, can judge in the condensed solvent and enter water, from the transparent vomit pipe 6 that is provided with of handleless cup 5 bottoms of looking the solvent of water mixing is emitted immediately, avoid water to enter reactor 1 and cause production accident.
Claims (3)
