Description
Technical field
This utility model belongs to comminutor technical field and in particular to the granulating mechanism of polyarylate resin production process.
Background technology
Polyarylate（PAR）It is a kind of high transparency amorphous thermoplastic special engineering plastics, its glass transition temperature（Tg）
194 DEG C, 174～175 DEG C of the heat distortion temperature under big load, can at 184 DEG C life-time service, the dimensional stability of product
Good, nontoxic, low hydroscopicity, high case hardness, resistance to ultraviolet shielded property are excellent, have high tensile 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 a kind of phase transfer catalysis interfacial polycondensation of polyarylate
Method preparation and process for separation and purification, belong to the new method of aromatic copolyester refining and edulcoration, are particularly suitable for the contracting of phase transfer catalysis interface
Poly- method synthesizes aromatic copolyester, goes out the sodium chloride of dereaction generation through deionized water wash, 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 being obtained after matter.
Polyarylate is sensitive to impurity, process conditions in preparation process, and the equipment therefore reacting used is also required to work and adapts to
Property improve the quality that just can ensure that normal production and final products.
Finally finished product is made in pelletize to be passed through to polyarylate, and polyarylate powder is sent into comminutor, through melting stretching and granulation.One
As, in the process, the height of water content directly affects the quality of final products quality, therefore needs the strict control to water content
System.
Utility model content
The purpose of this utility model is to provide a kind of granulating mechanism, the strict demand producing for polyarylate resin pelletize,
The water content of strict control material, removes volatile matters in material as much as possible it is ensured that the product quality of final polyarylate granule.
The technical scheme in the invention for solving the above technical problem is：A kind of polyarylate resin granulating mechanism, including
Melting granulator, and it is arranged on the Devolatilization device of this melting granulator front end, described Devolatilization device includes disengagement chamber, this disengagement chamber
Front-end configuration have air-flow feeding port, described disengagement chamber is configured with heating arrangement, and disengagement chamber cavity top uniformly offers pumping
Mouthful, the external exhaust tube of bleeding point, the volatile matters that material is blown from, into disengagement chamber, containing in material from air-flow feeding port are heated rising
Through arranging outside bleeding point, powder in material falls, and realizes the devolatilization to material before pelletize.
Preferably, described heating arrangement is the heater strip of heating mantle or spiral winding.
Compared with prior art, the utility model has the advantage of：Provide a kind of granulating mechanism, in melting granulator
Front end arranges Devolatilization device, carries out depth devolatilization to material, the moisture being blended in material, trace solvent etc. are removed further
Going, thus improve the degree of purity of material, contributing to obtaining the polyarylate granule of higher quality.
Brief description
Fig. 1 is the structural representation of granulating mechanism in this utility model embodiment.
Specific embodiment
Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.
As shown in figure 1, the polyarylate resin granulating mechanism in the present embodiment, including melting granulator 2, and it is molten to be arranged on this
Melt the Devolatilization device 1 of comminutor 2 front end, described Devolatilization device 1 includes disengagement chamber 1.1, and the front-end configuration of this disengagement chamber 1.1 has gas
Streaming material mouth 1.2, described disengagement chamber 1.1 is configured with heating arrangement, and disengagement chamber 1.1 cavity top uniformly offers bleeding point 1.3,
The external exhaust tube of bleeding point 1.3, material is blown from into disengagement chamber 1.1 from air-flow feeding port 1.2, and the volatile matters containing in material are subject to
Heat rises arranges through bleeding point 1.3 is outer, and the powder in material falls, and realizes the devolatilization to material before pelletize.
Above-mentioned heating arrangement is the heater strip 1.4 being spirally wound on disengagement chamber periphery.
The granulating mechanism of said structure arranges Devolatilization device in the front end of melting granulator, carries out depth devolatilization to material,
The moisture being blended in material, trace solvent etc. being removed further, thus improve the degree of purity of material, contributing to obtaining more
The polyarylate granule of high-quality.
In addition to the implementation, this utility model also includes other embodiment, all employing equivalents or equivalent
The technical scheme that substitute mode is formed, all should fall within this utility model scope of the claims.
