Liquid crystal liquid crystal property is generally presented when liquid crystal polyester material grain molten state.This kind of material has excellent heat resistance and molding processibility
Energy.For polymerization based on melt polycondensation, all aromatic LCP is aided with solid phase polycondensation so that high molecular weight products are made more.Non- Quan Fang
Fragrant race LCP plastic material produces product frequently with a step or two step melt polymerizations.Continuous fusion polycondensation produces high molecular weight LCP's
Technology is developed.Tensile strength and bending modulus can be more than the various thermoplastic engineering plastics to grow up.Mechanical performance, ruler
Very little stability, optical property, electrical property, chemical resistance, anti-flammability, processability are good, heat-resist, thermal expansion coefficient compared with
It is low.
The process of thermotropic liquid crystalline polyester is usually to melt copolymerization, then carries out pelletizing, needs not being inconsistent after pelletizing
The material grain for closing particle size requirements sieves removal, improves product qualification rate, during directly being sieved after pelletizing, material
Grain is without be easy to causeing adhesion, so that product qualification rate is reduced by being fully cooled.
To solve the above-mentioned problems, Chinese patent CN201320655181.2 proposes a kind of production of CABLE MATERIALS grain with air-cooled
Formula hummer screen, the patent are cooled down using setting air blower to CABLE MATERIALS grain, avoid CABLE MATERIALS grain that " clay " phenomenon occurs, but
It is the setting of air blower, leads to expect that clustering phenomena occurs under the action of the forces of the wind between grain, be less useful for its dispersion, adhesion phenomenon
It is not solved effectively.
Summary of the invention:
The purpose of the present invention is providing a kind of liquid crystal polyester material grain screening plant in view of the above problems, can effectively avoid
Liquid crystal polyester material grain sticks together in screening process, improves the qualification rate of liquid crystal polyester material grain.
Above-mentioned purpose is realized by following technical scheme:
Liquid crystal polyester material grain screening plant, including sieve nest, the sieve nest bottom pass through spring support seat connection plate, the sieve
Body bottom is provided with the exciting plate with the sieve nest bottom in 45° angle, and the strike exciting plate is provided on the mounting plate

Group spraying ventilating device, the spraying ventilating device connect cold water pipe, and the sieve nest bottom is provided with recycling sink, the recycling
Sink connects recovery tank.
The liquid crystal polyester material grain screening plant, the sieve nest include the bottom plate positioned at the recycling sink top, institute
The drainage hole being provided on bottom plate towards the sink is stated, the surrounding of the bottom plate is provided with side plate, passes through branch on the side plate
Frame connects two layers of sieve plate and is located at aperture of the aperture greater than the sieve plate positioned at lower layer of the sieve plate on upper layer, setting at the top of the side plate
There is dust-proof top plate, the bottom of sieve plate side described in every layer has the discharge port.
The liquid crystal polyester material grain screening plant, the spraying ventilating device includes the spray connecting with the cold water pipe
Water pipe, is provided with one group of spray head on the spray waterpipe, the installation direction of the spray head vertically with the sieve plate.
The liquid crystal polyester material grain screening plant, the vibration excitor includes driving motor, the driving motor
Mounting disc, the hinged one group of peening hammer in the periphery of the mounting disc are provided on power output shaft.
The liquid crystal polyester material grain screening plant, is provided with stiffening plate between the exciting plate and the sieve nest.
The utility model has the advantages that
The present invention cools down to material grain, is avoided the adhesion of material grain by the way of spraying cooling, relative to wind cooling temperature lowering,
Do not allow it is easier that expect grain occur clustering phenomena, can effectively avoid liquid crystal polyester material grain from sticking together in screening process, improve
The qualification rate of liquid crystal polyester material grain.
