Abstract
The utility model belongs to the field of chemical equipment, and in particular relates to reaction agitation equipment. The reaction agitation equipment mainly comprises a reaction kettle, wherein a stirring shaft is arranged inside the reaction kettle; arch agitation paddles are connected with the bottom end of the stirring shaft through a shaft sleeve and are integrated with the shaft sleeve. A conventional agitation mode is not advantageous to sufficient combination of a catalyst and material. By adopting the agitation mode of the reaction agitation equipment, the catalyst at the bottom can be agitated up, so that the catalyst comes into full contact with the material, and the reaction can be carried out favorably, the product quality can be guaranteed, and the percent conversion of products can be improved; the two propeller agitation paddles are advantageous to up-down turning of the material, so that concentrated sulfuric acid, methylbenzene and isobutylene can be sufficiently combined.
Description
Technical field
The utility model belongs to the chemical industry equipment field, is specifically related to a kind of reaction mixing plant.
Background technology
A kind of important chemical intermediate of p-tert-butyltoluene, normally adopt sulfuric acid catalysis, with toluene and isobutene, is raw material production.Because sulfuric acid and toluene do not dissolve each other, the amount that sulfuric acid adds is on the low side, and the heavier meeting of proportion sinks to the bottom of still.Existing mixing plant can not well stir sulfuric acid, thereby causes catalytic effect bad, affects the quality of production efficiency and product.
Summary of the invention
The utility model has designed a kind of reaction mixing plant for the problems referred to above, and purpose is: catalyst is fully contacted with material, be conducive to reaction and carry out, improve conversion rate of products and quality.
The technical solution adopted in the utility model is:
A kind of reaction mixing plant, mainly comprise reactor, it is characterized in that: described reactor inside is equipped with shaft, and described shaft bottom is connected with arc stirrer paddle by axle sleeve, and described stirrer paddle and axle sleeve are one-body molded.
Described axle sleeve is connected with shaft by spiral way, and locks by flange, and pad also is installed between described flange and axle sleeve.
Described axle sleeve is connected with shaft by pluggable mode, and passes through screw locking.
Described arc stirrer paddle comprises by-level blade, oblique blade and both ends horizontal blade.
Described oblique blade and by-level blade and both ends horizontal angle between oars are between 119-120 °.
Described stirrer paddle top also is equipped with two pusher stirring vanes.
The utility model beneficial effect:
General whipped form is unfavorable for the abundant combination of catalyst and material.Adopt whipped form of the present utility model, bottom catalysis is stirred, realized that catalyst fully contacts with material, be conducive to the carrying out of reaction, the quality of product is guaranteed, but also has improved the conversion ratio of product; Two pusher stirrings of installing, be conducive to stirring up and down of material and make the abundant combination of the concentrated sulfuric acid and toluene and isobutene.
The accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is stirrer paddle structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
Embodiment:
As depicted in figs. 1 and 2, a kind of reaction mixing plant, mainly comprise reactor 1, reactor 1 inside is equipped with shaft 2, the shaft bottom is connected with arc stirrer paddle 3 by axle sleeve 4, the stirrer paddle top also is equipped with two pusher stirring vanes 5, axle sleeve 4 is connected with shaft 2 by spiral way, and lock by flange, pad also is installed between described flange and axle sleeve, perhaps axle sleeve is connected with shaft by pluggable mode, and pass through screw locking, stirrer paddle and axle sleeve are one-body molded, arc stirrer paddle comprises by-level blade 31, oblique blade 32 and both ends horizontal blade 33, tiltedly blade and by-level blade and both ends horizontal angle between oars are between 119-120 °.
The bottom that is stirred in shaft is fixed, and stirs downward angle is arranged, and makes to stir the bottom of close as much as possible still.The catalyst of bottom is fully stirred, be dispersed in solvent.Operating procedure is as follows:
1. reactor is opened and is stirred first solubilizer (toluene) when adding material, and then adds catalyst (concentrated sulfuric acid).
2., in the process added at catalyst, due to the heavier deposition that has of the proportion of sulfuric acid, bottom is stirred and can well the sulfuric acid of deposition be stirred fully and be dispersed in solvent.
3. material adds end, cools to reaction and requires temperature to lead to isobutene to be reacted.
The utility model produces a desired effect.
Claims (6)
