Abstract

The utility model relates to a pelletizer with six groups of blades for smashing light metal, which is a smasher especially used for smashing and granulating light metal, such as magnesium, aluminium, magnalium, etc. The utility model is formed by connecting a main engine, a draught fan, an engine base, a pipe, a cyclone discharger, a motor, a belt pulley, a spindle, a cutter blade, a cutter head partition board, a bearing, a bearing seat, a bearing cooling water jacket, a tooth-shaped spiral groove lining board, a casing and a cutter head. When the utility model is used, the motor drives the main engine to rotate at the speed of 3500r/min, and a rotor and a stator smash the materials together. The smashed materials are guided out of the main engine by the draught fan, are delivered to the cyclone discharger through the pipe and are gathered by the cyclone discharger. Thus, the smashing purpose is obtained.

Description

Six groups of blade light metals are pulverized comminutor

One technical field: the utility model relates to a kind of pulverizer that light metals such as magnesium, aluminium, magnadure are pulverized granulation that is specifically designed to, and especially six groups of blade light metals are pulverized comminutor.

Two background technologies: the pulverizer that is used for the light metal pulverizing in the past, because the set of blades number is few (mostly to be 4 groups most, 64 blades), the mill thorax is short, make that the circularity of the metallic particles after pulverizing is relatively poor. when the magnesium granules after particularly pulverizing uses as the steel desulfurization agent,, make that the flowability of desulfurizing agent is poor because degree of rounding of grains is poor, very easy stifled rifle. reduce the production efficiency of steel-making, increased the STEELMAKING PRODUCTION cost.

As blindly increasing the set of blades number. the pulverizing heat in the crushing process is increased, gently then make the flavescence of magnesium grain, blackening lose use value, heavy then cause and burn breaking out of fire.

Three, summary of the invention: the purpose of this utility model provides six groups of blade light metal powder machines, and it increases the group number of blade, improves the circularity of pulverizing the back metallic particles. but do not increase the pulverizing heat, keep the physicochemical properties of particle.Make it meet the GB5149.1-2004 requirement, the purpose of this utility model is to realize like this, it is to be formed by connecting by main frame, air-introduced machine, support, pipeline, whirlwind discharger, motor, belt pulley, main shaft, blade, cutterhead dividing plate, bearing, bearing block, bearing cooling water cover, profile of tooth helicla flute liner plate, housing, cutterhead, main frame, motor with bolting on base, main frame is connected with driving-belt with motor; Middle bottom at pipeline is installed with air-introduced machine; The whirlwind discharger is installed in an end top of pipeline; Main shaft is positioned at housing, and belt pulley is installed in an end of main shaft; The other end at main shaft is installed with bearing, bearing block; The bearing cooling water cover is installed in but bearing use of cooling on the bearing block; Bearing block is fixed on the housing; 6 groups of cutterheads are being worn in equilibrium on the main shaft, and 14 blades are installed on every group of cutterhead, and the cutterhead dividing plate lays respectively in the middle of 6 groups of cutterheads; Fixing profile of tooth helicla flute liner plate in the housing, promptly on the liner plate inwall profile of tooth helicla flute is being arranged.

During work, the driven by motor main frame is with the speed rotation of 3500r/min, and material is pulverized in rotor, stator acting in conjunction. and the material after air-introduced machine will be pulverized is drawn main frame, sends to the whirlwind discharger by pipeline, by the whirlwind discharger with material collection, thereby reach the purpose of pulverizing.

The utility model has increased the group number of blade, be increased to six groups by four groups, blade adds up to 84, in order to improve crushing effect, improve the circularity of metallic particles. adopt helicla flute profile of tooth liner plate simultaneously, make metallic particles in the process of pulverizing, groove on the profile of tooth helicla flute liner plate of the effect lower edge of cutterhead back air-swirl rolls and collides, bounds forward, thereby the time of contact of prolongation and air. the heat on the increase metallic particles has reduced the temperature rise of metallic particles in pulverizing to the radiation of air. kept the physicochemical properties of magnesium grain.
