Abstract
The utility model discloses a p-hydroxy benzaldehyde crystallization kettle which comprises a crystallization kettle body and a stirring motor, wherein a crystallization kettle jacket is arranged on the outer wall of the crystallization kettle body, and the stirring motor is connected with an outer wall-scraping blade and an inner driving blade; the inner driving blade is arranged in the central position in the crystallization kettle body, and the outer wall-scraping blade is arranged in a position close to the inner wall of the body, of the crystallization kettle body. With the adoption of the inner driving blade, materials in the crystallization kettle can be fully stirred, so that the materials in the crystallization kettle can better flow, thereby realizing effective mixing of the materials and the uniformity of the materials in the kettle. The outer wall-scraping blade can effectively prevent the crystallized materials from being adhered to the inner wall of the crystallization kettle, thereby greatly improving the heat transfer effect and the capacity of the product.
Description
Technical field
The utility model relates to a kind of crystallization kettle of medicine intermediate, particularly a kind of parahydroxyben-zaldehyde crystallization kettle.
Background technology
P-methoxybenzal-dehyde is a kind of important chemical intermediate, and in manufacturing process, the main paracresol that adopts is oxidized to parahydroxyben-zaldehyde, and then uses parahydroxyben-zaldehyde to react with dimethyl suflfate, generates P-methoxybenzal-dehyde.
After wherein paracresol is oxidized to parahydroxyben-zaldehyde, need decrease temperature crystalline, then the centrifugal parahydroxyben-zaldehyde that obtains; The crystallized stock viscosity is high, in the decrease temperature crystalline process, easily on the crystallization kettle wall, adheres to, and affects heat-transfer effect, thus the production capacity of restriction product.
Summary of the invention
In order to overcome above-mentioned defect, the utility model provides a kind of can effectively solve the parahydroxyben-zaldehyde crystallization kettle that crystallized stock adheres to the crystallization kettle inwall.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of parahydroxyben-zaldehyde crystallization kettle, comprise crystallization kettle body and stirring motor, described crystallization kettle body outer wall is provided with the crystallization kettle chuck, described stirring motor is connected with outer scrape wall blade and interior driving blade, described interior driving blade is arranged on the central interior position of crystallization kettle body, the described outer position that the wall blade is arranged on close crystallization kettle inner body wall in the crystallization kettle body of scraping.
As further improvement of the utility model, described interior driving blade is the rectangle flaabellum shape.
As further improvement of the utility model, described outer to scrape the wall blade be frame.
The beneficial effects of the utility model are: in adopting, drive blade the material in crystallization kettle can be stirred fully, material in crystallization kettle can be flowed preferably, realized effective mixing of material, and the homogeneity of the interior material of still; Scrape the material that the wall blade can effectively prevent that crystallization from going out outward and stick on the crystallization kettle inwall, greatly improved heat-transfer effect, thereby improved the production capacity of product.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1, crystallization kettle body, 2, the crystallization kettle chuck, 3, mix drive motors, 4, scrape the wall blade outward, 5, interior driving blade.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail.
A kind of parahydroxyben-zaldehyde crystallization kettle as shown in Figure 1, comprise crystallization kettle body 1 and stirring motor 3, the outer wall of described crystallization kettle body 1 is provided with crystallization kettle chuck 2, described stirring motor 3 is connected with outer scrape wall blade 4 and interior driving blade 5, described interior driving blade 5 is arranged on the central interior position of crystallization kettle body 1, and the described outer wall blade 4 of scraping is arranged on the interior position near inner body wall of crystallization kettle body 1.
Described interior driving blade 5 is the rectangle flaabellum shape.
The described outer wall blade 5 of scraping is for frame.
The course of work of the present utility model is: after material to be crystallized enters crystallization kettle body 1, start stirring motor 3, stirring motor 3 drives outer scrape wall blade 4 and 5 work of interior driving blade simultaneously, pass into cooling medium in crystallization kettle chuck 2, for to the material cooling, along with the reduction of crystallization kettle body 1 interior temperature of charge, there is gradually material to separate out, scrape the material that wall blade 4 can effectively prevent that crystallization from going out outward and adhere on crystallization kettle body 1 inwall, affect the transmission of heat; Under the effect of interior driving blade, in still, material can flow preferably, guarantees the homogeneity of material, has greatly improved heat-transfer effect, thereby has improved the production capacity of product.
