Description
Technical field
The present invention relates to chemical industry equipment production field, particularly relate to a kind of epoxy soybean oil process for processing high efficiency reactor.
Background technology
Be light yellow sticky oily liquids at normal temperatures, the solubleness <0.01(25 DEG C in water), the solubleness 0.55%(25 of water in these product ° C) and, be dissolved in the organic solvents such as hydro carbons, ketone, ester class, higher alcohols, be slightly soluble in ethanol.These product are that a kind of most popular nontoxic polyvinyl chloride softening agent is held concurrently stablizer: good with polyvinyl chloride resin consistency, volatility is low, transport property is little.Have excellent thermostability and light stability, water tolerance and oil-proofness are also good, can give the good physical strength of goods, weathering resistance and electrical property, and nontoxicity, be the chemical technology auxiliary agent for packaging material for food of international endorsement.These product can be used for all polrvinyl chloride products.As varieties of food items wrapping material, medical product, various film, sheet material, tubing, refrigerator strip of paper used for sealing, leatheroid, flooring laminate, plastic wallpaper, electric wire and other daily plastic goods etc., also can be used for special ink, paint, coating, synthetic rubber and liquid composite stabilizing agent etc.
In the use procedure of reality, it is not good also to there is color and luster in epoxy soybean oil, problem of low quality, this is mainly relevant with epoxy soybean oil response situation in the reactor, mainly there is following shortcoming in existing reactor, it causes the of low quality of epoxy soybean oil, one: the reaction process of epoxy soybean oil is steady not, main relevant with the speed adding batching, add the excessive velocities of batching or excessively all can affect reaction effect slowly, therefore, the epoxy soybean oil in order to obtained better quality just strictly must control the feed rate of admixtion, can not be too fast; Secondly, for the preparation of chemical field, stirring in reaction process is also one of factor of obtained better product, and existing stirring arranges more traditional, only two panels agitating vane is adopted to complete the stirring reaction of epoxy soybean oil, make mixing evenness poor, thus cause the quality product of producing to there is the phenomenons such as reaction is incomplete; Again, the reaction of epoxy soybean oil needs to react in the environment of heating, because the rising of temperature can fast reaction speed and reaction effect, and steam of the prior art directly passes into retort to heat, there is upper end and heat rapidly in this type of heating, and lower end is heated comparatively slow, there is the temperature difference, cause the reaction of the reaction of upper end and lower end not carry out simultaneously, thus cause top and bottom product there is mass discrepancy.
Summary of the invention
For above-mentioned Problems existing, the present invention aims to provide a kind of epoxy soybean oil process for processing high efficiency reactor, this reactor structure is simple, easy handling, can uniform stirring be realized, uniform feeding and thermally equivalent, thus improve the quality of production of epoxy soybean oil, production efficiency, and then increase economic efficiency.
To achieve these goals, the technical solution adopted in the present invention is as follows:
Epoxy soybean oil process for processing high efficiency reactor, comprise retort and whipping appts, described retort is sealed by urceolus and inner core and forms, the sealing of described retort upper end arranges lid, inner chamber body is formed between described urceolus and described inner core, in described inner chamber body, steam coil pipe is set around described inner core, the through connection steam inlet duct in described steam coil pipe top, the side that described lid is relative all arranges inclination feed chute, and described lid portion inside arranges the shunting disk be connected with described inclination feed chute; Described whipping appts comprises stirring main shaft, the upper end of described stirring main shaft is fixed on described lid, and drive driving by drive-motor, equidistant from the top down on described stirring main shaft two opposite sides some stirring transverse axis are set, each described stirring transverse axis upper surface and lower surface are all set up in parallel some stirring pieces, and each described stirring piece two opposite sides are all fixedly connected with some taper stirrer gears.
Further, described shunting disk arranges some blanking holes, in each described blanking hole, one connects shunting funnel.
Further, described shunting disk arranges protective sleeve with the described stirring main shaft place of combining.
Further, described steam coil pipe has some cores.
Further, the range of tilt angles of each described inclination feed chute at 30 ~ 45 °, and vertically arranges opening for feed on each described inclination feed chute.
Principle of the present invention and beneficial effect are: first, the present invention is adopt all to arrange stirring piece arranged side by side on stirring transverse axis upper surface and lower surface solving in the problem stirring inequality, stirring piece two relative side is all symmetrical arranged taper stirrer gear, stirring main shaft drives in the process stirring transverse axis stirring, epoxy soybean oil is thick because of it, so adopt taper stirrer gear by its sharp-pointed tapered portion potential energy enough to stirring liquid shearing force, under the acting in conjunction of multiple taper stirrer gear shearing force, the stirring dynamics stirring liquid reaches maximum, mixed effect reaches best, ensure that reacting completely of reaction solution simultaneously, stir, by product is few, output can be improved, secondly, the present invention is binding pattern retort being adopted to inside and outside cylinder solving in the uneven problem of heating, steam coil pipe is set in the inner chamber body between inside and outside cylinder, steam disc pipe winding disk encloses around inner core one, can to liquid upper and lower in retort reacting by heating simultaneously by steam coil pipe, avoid reacting up and down uneven phenomenon to occur, thus cause quality product slightly in the phenomenon of difference, improve the consistence of resultant in whole retort, again, the present invention solution blanking too fast or cross slow problem be adopt a shunting disk is set, in addition the inclination feed chute on lid is arranged in addition, admixtion directly enters inclination feed chute by opening for feed, inclination feed chute is by its inclination advantage, to admixtion one surging force obliquely, admixtion enters on shunting disk with speed faster, shunting disk there are some funnel holes, fixed installation shunting funnel below funnel hole, strictly can not only be controlled the discharge quantity of admixtion by shunting funnel, the even blanking of admixtion can also be ensured, kill two birds with one stone.
