The production process route of amino film plastics has 2 at present, and one is wet route, and another is the BUSS method that Switzerland BUSS company creates.Wet route is: urea (melamine) and formaldehyde at first generate resin in reactor, then filler and other auxiliary materials in kneader and mixed with resin, again at the drier inner drying, then pulverizing, ball milling, be screened into end product.And the BUSS method had only for 2 steps: urea becomes Lauxite with formolite reaction, and Lauxite adds other fillers after entering reactor, and the mixing dehydration of high speed is the direct pelletized product that gets.In the BUSS technology, reactor is the equipment of most critical in the technological process, and this equipment has multiple functions such as kneading, polymerization, painted, density, dehydration, controllable grain size granulation.This equipment can satisfy the production needs when introduce in Europe substantially.Along with high-grade amino film plastics product constantly develops to high extreme direction, to continue to optimize prescription, improve technology, this reactor demonstrates gradually and can not meet the needs of production.Be mainly reflected in: when setting electric current with minimum speed, the production time increases by 20%; When setting electric current with the production cycle, minimum speed is too high again, and the particle diameter of the finished product of producing is too big.In production technology, this equipment can not be taken into account product quality and production efficiency.To the technological transformation that this reactor carries out, be conceived to the agitating device in the reactor.This agitating device is a dasher, and critical piece has blade, key, the axle collar, vertical pivot, decelerator, contacts at most with material in it, and the parts that material is directly had the greatest impact are exactly blade, must transform the blade structure.
The utility model content
At above technical problem, the utility model provides a kind of structure that is applied to prepare the built-in blade of vacuum reaction still of amino film plastics, the structure of described blade comprises propeller hub, blade, have two blades on each propeller hub at least, the end that blade and propeller hub join is a blade root, and the blade outermost end is a blade tip, blade root is that blade is long to the distance of blade tip, to 1/2 blade strong point, till blade tip, blade twists around lagging edge from distance blade root 1/6 blade length.Blade is main in reactor to play mixed material, and makes material ascension in reactor, makes it the fully effect of reaction.Through technical staff's repetition test, changing original straight blades is the blade of existing part distortion, can increase thrust.This design makes reactor set under the current conditions at minimum speed, and the production time meets technological requirement; And when setting electric current with the production cycle, the blade mixing speed can make the amino film plastics grain diameter reach quality standards just.
As a technological improvement of the present utility model, by experimental results demonstrate: the angle between leaf curling part and the horizontal plane between operating current, production time, end product quality, reaches an optimal balance point 15 when spending between 25 degree.
In addition, when adopting the blade of straight blades, the lagging edge of blade has corner angle in the past.In the course of the work, the material with stickiness can be attached on the blade lagging edge, drops from lagging edge after progressively being accumulated as agglomerate.This material agglomerate is fully handled without technologies such as kneading, polymerization, painted, density, dehydrations, sneaks into other behind the broken granulating fully in materials of reaction.Producer is in case when making the plastics apparatus with such amino film plastics particle thermoplastic shaping, forms on plastics apparatus surface that fault, especially naked eyes are difficult to discover but fault that available colour difference meter detects, in case appearance, this batch products is scrapped.Through technical identification, change lagging edge into rounded corner, can prevent effectively that material from sticking, reduce the fault that drops and cause because of the material agglomerate, improve the quality of products.
As a technological improvement of the present utility model, A-A is designed to wedge shape to section with blade, and thickness successively decreases to guide margin from lagging edge, has improved the kinetic effect of blade in multiphase flow, promotes material ascension reaction in reactor.
