Abstract

The utility model discloses a reactor, which relates to chemical mechanical equipment and comprises a reactor body and a reactor cover. A stirring system is arranged in the reactor. The reactor is characterized in that another stirring system is disposed in the reactor, and the two stirring systems are symmetric relative to the center line of the reactor body and are arranged in a vertically staggered manner. The reactor has the advantages that the reactor is simple in structure, high in stirring efficiency and fine in stirring effect, yield of products is improved, a stagnation area is eliminated, wall adhesion is prevented, and the reactor is applicable to reaction of viscous materials.

Description

A kind of agitated reactor
Technical field
The utility model relates to a kind of chemical mechanical equipment, specifically is a kind of agitated reactor.
Background technology
The agitated reactor that uses at present is of a great variety, generally is useful on the agitated reactor that stirs sticky material, and this type of agitated reactor is connected motor and reductor and charging aperture and constituted by kettle, kettle cover, single cover shaft.The kettle wall has sandwich, is used for controlling the agitated reactor material temperature.On shaft, be connected with single stirrer paddle, mostly the shape of blade is anchor formula, oar formula, frame etc., realizes the stirring to reaction mass.Shaft is vertically mounted on the center of kettle cover, through flange seal.
The shortcoming that such agitated reactor exists is following:
1, single agitator stirring efficiency is low: form dual horizontal circulation field structure up and down at paddle, immixture forms the cave strongly, and other regional fluids flow slowly, and turbulent extent is low, and mixed effect is poor.There is the stagnant wake in zone away from paddle.
2, relatively poor mixing effect causes near the sticky material heat-transfer effect in heating process of still wall poor, has bigger thermograde, and what influence was reacted normally carries out, and product yield is low, and material is prone to glue wall simultaneously.
3, because mostly stirrer paddle is planar structure, stirring efficiency is low.
Summary of the invention
The utility model is in order to remedy the deficiency of prior art, and a kind of simple in structure, stirring efficiency is high, mixing effect is good agitated reactor is provided.
The utility model comprises the cover stirring system in the agitated reactor that is arranged at kettle and kettle cover composition; Its special character is: be provided with another set of stirring system in the described agitated reactor, described two cover stirring systems are with the center line symmetry of kettle and the setting that is in staggered distribution up and down.Two stirring systems motor rotation direction when work is opposite, is provided with the two cover stirring systems that are in staggered distribution up and down and has improved mixing effect.Form four dual horizontal annular flow fields around in agitated reactor, macroscopic view presents cavernous shape, has eliminated the stagnant wake, has improved the turbulent extent of sticky material.Four caves are interspersed up and down, are prone to take place reciprocation between the cave, and the stirring of marginal zone, cave also is able to strengthen.The raising of mixing effect has improved the heat transfer efficiency of sticky material, has improved the temperature controlled degree of accuracy, has improved the yield of product.In addition, inner wall of kettle is done polishing, on the basis of improving stirring efficiency, has avoided the generation of wall sticking phenomenon.
The top of the shaft in the described two cover stirring systems is equipped with the stirrer paddle vertical with shaft, and the bottom of described shaft is equipped with and shaft stirrer paddle in a certain angle and acclivitous.Described top rade degree is the 50-70 degree, and is preferred, and the top rade degree of paddle is 60 degree.
Described stirrer paddle is three curved blade type stirrer paddles.Three curved leaf stirrer paddles of stereochemical structure, mechanical strength is big, and mixing effect is greatly enhanced.
The beneficial effect of the agitated reactor of the utility model: simple in structure, stirring efficiency is high, mixing effect good, improved product yield, eliminate the stagnant wake, prevent sticking wall, be applicable to the occasion of sticky material reaction.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
Accompanying drawing is a kind of specific embodiment of the utility model; This embodiment comprises the cover stirring system in the agitated reactor that is arranged at kettle 1 and kettle cover 3 compositions; Be provided with another set of stirring system in the described agitated reactor, described two cover stirring systems are with the center line symmetry of kettle 1 and the setting that is in staggered distribution up and down.Shaft I 10 tops in the first cover stirring system in the described kettle 1 are provided with run-in index stirrer paddle I 11; The bottom is provided with inclined stirrer paddle I 12; Shaft II 20 tops of the described second cover stirring system are provided with run-in index stirrer paddle II 21, and the bottom is provided with inclined stirrer paddle II 22.
The utility model is at first put into the chemical substance of reaction needed in use through the charging aperture 5 that is arranged at kettle cover 3 sidepieces, in chuck 4, feed heating or cooling medium control reaction temperature from water inlet 15.After the preparation of a series of grades is ready; Restart the motor I 9 and motor II 16 that are arranged at kettle cover 3 tops; Motor I 9 is opposite with motor II 16 rotation directions, motor I 9 and decelerator I 8 and 10 coaxial connections of shaft I, motor II 16 and reductor II 17 and 20 coaxial connections of shaft II; It is opposite with shaft II 20 rotation directions so just can to drive shaft I 10; Form the recection type rotation during stirring, be arranged at shaft I 10 simultaneously respectively and bend the leaf paddles, improved mixing effect with horizontal three curved leaf paddles and last inclined three on the shaft II 20.Form four dual horizontal annular flow fields around four blades, macroscopic view presents cavernous shape, has eliminated the stagnant wake, has improved the turbulent extent of sticky material.Four caves are interspersed up and down, are prone to take place reciprocation between the cave, and the stirring of marginal zone, cave also is able to strengthen.The raising of mixing effect has improved the heat transfer efficiency of sticky material, has improved the temperature controlled degree of accuracy, has improved the yield of product.Just can material be discharged from kettle 1 through drain hole 13 after reaction finishes, the heating or cooling mediums in the chuck 4 are emitted from delivery port 14, and whole process operation is simple, and is convenient and easy.In addition, the two cover stirring systems that are provided with in the agitated reactor also can be two cover stirring systems inequality, as long as can reach good mixing effect.
