Abstract

This utility model relates to a kind of polyarylate resin production centrifuge, it is applicable to polyarylate resin produce, material after desolvation is further dried acquisition powder, including centrifugal chamber, described centrifugal chamber is configured with water inlet pipe, described centrifugal chamber inwall is provided with filter screen, and the mesh number of described filter screen is between 400～600 mesh.By configuring water inlet pipe to centrifugal chamber, at the centrifugal initial stage, by water inlet pipe to centrifugal chamber inner water-supply, coordinate centrifuge that suitable rotating speed is set again, make the sodium chloride dissolution as far as possible of remnants and throw away with water, being stripped of in powder the sodium chloride of remnants further, while dried material, also purified product.

Description

A kind of polyarylate resin production centrifuge

Technical field

This utility model belongs to Centrifuge Techniques field, is specifically related in polyarylate resin production process get rid of powder Dry centrifuge.

Background technology

Polyarylate (PAR) is a kind of high transparency amorphous thermoplastic special engineering plastics, its glass transition temperature (Tg) About 194 DEG C, the heat distortion temperature 174 under big load～175 DEG C, can at 184 DEG C life-time service, the dimensional stability of goods Hydroscopicity good, nontoxic, low, high case hardness, resistance to ultraviolet shielded property are excellent, have high hot strength and toughness, It is widely used in the fields such as aviation, automobile, electronic apparatus, LED illumination, medical apparatus and instruments and energy traffic.

The patent of invention of Authorization Notice No. CN103965452B discloses the phase transfer catalysis interfacial polycondensation of a kind of polyarylate Method preparation and process for separation and purification, belong to the new method of aromatic copolyester refining and edulcoration, is particularly suitable for the contracting of phase transfer catalysis interface Poly-method synthesis aromatic copolyester, goes out, through deionized water wash, the sodium chloride that dereaction produces, and the machinery being filtered to remove in resin liquid is miscellaneous The resin separating-purifying of smart resin liquid, pulverizing and the solvent recovery reutilization technology prepared after matter.

Polyarylate is to impurity, process conditions sensitivity in preparation process, and the equipment therefore reacting used is also required to work and adapts to Property improve and just can ensure that normal production and the quality of final products.

During polyarylate polyreaction in a kettle., finally from reactor bottom discharge, reactant to be mixed with reaction Side product chlorinated sodium and solvent etc., these impurity materials must be separated off just obtaining pure poly-virtue from reaction system Ester resin.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of centrifuge, this centrifuge for above-mentioned prior art That the powder after desolvation is made further centrifugal drying, while dry powder to powder in remaining sodium chloride enter one Step removing.

The technical scheme in the invention for solving the above technical problem is: a kind of polyarylate resin production centrifuge, Including centrifugal chamber, described centrifugal chamber is configured with water inlet pipe, and described centrifugal chamber inwall is provided with filter screen, the mesh number of described filter screen between 400～600 mesh.

Compared with prior art, the utility model has the advantage of: provide a kind of centrifuge, by configuring to centrifugal chamber Water inlet pipe, at the centrifugal initial stage, by water inlet pipe to centrifugal chamber inner water-supply, then coordinates centrifuge to arrange suitable rotating speed, makes remnants Sodium chloride dissolution as far as possible and throw away with water, be stripped of further in powder remnants sodium chloride, purify product.

Accompanying drawing explanation

Fig. 1 is the structural representation of centrifuge in this utility model embodiment.

Detailed description of the invention

Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.

As it is shown in figure 1, the centrifuge in the present embodiment, it is adaptable to polyarylate resin produces, to the material after desolvation Acquisition powder being further dried, is configured with water inlet pipe 1 including centrifugal chamber a, described centrifugal chamber a, described centrifugal chamber a inwall is provided with Filter screen 2, the mesh number of described filter screen is between 400～600 mesh.

Above-mentioned centrifuge, by configuring water inlet pipe to centrifugal chamber, at the centrifugal initial stage, is sent in centrifugal chamber by water inlet pipe Water, then coordinate centrifuge that suitable rotating speed is set, make the sodium chloride dissolution as far as possible of remnants and throw away with water, being stripped of further Sodium chloride remaining in powder, has also purified product while dried material.

In addition to the implementation, this utility model also includes other embodiments, all employing equivalents or equivalence The technical scheme that substitute mode is formed, within all should falling into this utility model scope of the claims.

Claims (1)

1. a polyarylate resin production centrifuge, it is characterised in that: include that centrifugal chamber, described centrifugal chamber are configured with into water Pipe, described centrifugal chamber inwall is provided with filter screen, and the mesh number of described filter screen is between 400～600 mesh.
