Description

The rubber and plastic pulverizer

The utility model relates to a kind of pulverizer, particularly a kind of rubber and plastic pulverizer that is used for crushing rubber and plastics.

Along with the development of rubber and plastics industry, rubber and plastic products are increasing, and what accompany with it is that scrap rubber and waste plastics also are doubled and redoubled.If with paying no attention to of abandoning of scrap rubber and waste plastics or flow or blow over and cover completely or burn, not only polluted environment but also wasted resource, in fact, can utilize again after scrap rubber and waste plastics made it to reach certain particle by pulverizing, as in the production that rubber powder or molding powder is joined rubber and plastic products or join during other industrial goods produce, both can reduce production costs, can improve the performance of industrial products again.Be used for pulverizer difference to some extent of crushing rubber and plastics at present owing to the different of crushing mechanism; but generally speaking; present pulverizer exists the edge of a knife easy to wear; the general use must be changed in 2～3 days, and energy consumption is big, yields poorly; crushing effect is poor; noise is big, and structural design is unreasonable, shortcomings such as normal generation shutdown.

The purpose of this utility model provides a kind of good crushing effect, long service life, and energy consumption is low, the rubber and plastic pulverizer that noise is little.

The purpose of this utility model is achieved in that it comprises body, cutterhead, stationary knife, driving shaft, screen cloth, motor.The body top is provided with charging aperture, the below is provided with discharging opening, the centre is the crushing chamber that is complementary with cutterhead, cutterhead is fixed on the driving shaft and places in the pulverizing cavity of body, driving shaft by driven by motor is fixed by bearing arrangement and body, be provided with the stationary knife of shearing mutually with cutterhead in the pulverizing cavity of body, screen cloth is arranged on the discharging opening place.The cutterhead that the utility model adopted is made of disk body and blade, and the center of circle, disk body upper edge direction has triangle cutter groove, and wherein the subsides knife face of cutter groove is vertical with disk body cylindrical tangent line, another side with paste knife face have a certain degree (as 90 °).Simultaneously, not parallel tangent but become to intersect shearing mutually when cutterhead is sheared mutually with stationary knife, the subsides knife face of cutter groove becomes 8～15 ° with the surface of cutterhead.Blade is fixed on the subsides knife face of cutter groove by screw.In order to improve shear effect, the tilting side that makes powder shift crushing chamber onto of reason cutterhead cutter not, cutterhead of the present utility model generally adopts even number to be provided with in pairs, as 1～4 pair, the blade of every pair of cutterhead becomes crossing condition, and powder is extruded between every pair of cutterhead like this, has improved the effect of shearing.The edge of a knife quality of blade is the effect of influence pulverizing directly, and in order to improve the intensity of the edge of a knife, the utility model is at knife-edge part welding one deck hard alloy layer.Blade on stationary knife and the cutterhead forms mutual shearing condition, the utility model adopts two stationary knifes, and two stationary knifes are separately positioned on the both sides in the crushing chamber, because body divides upper machine body and lower body, therefore, two stationary knifes can be separately positioned on the crevice place of upper machine body and lower body both sides.The pulverizing power consumption of rubber and plastics is big, and very most electric energy is transformed into heat energy, therefore, must cool off body and bearing arrangement, the utility model is provided with the bearing cooling chamber between bearing arrangement and body fuselage, be provided with the body cooling chamber in four angles up and down at body.Motor drives driving shaft by belt pulley and rotates at a high speed, in order to improve the inertia of rotation, and energy efficient, the utility model end relative with belt pulley on driving shaft is provided with flywheel.The course of work of the present utility model is: rubber mass or plastics are sent into from charging aperture, the cutterhead of rotation is pressed into material and pulverizes in the cavity at a high speed, and shear pulverizing through blade on the cutterhead and the stationary knife on the body, because the blade on the every pair of cutterhead is arranged in a crossed manner, therefore material mutual extrusion between cutterhead has improved and has sheared the effect of pulverizing, and falls on the screen cloth through the material of shearing after grinding, and through the screening of screen cloth, make satisfactory powder by screen cloth from discharge hole for discharge.Four body cooling chamber water pipes in the body connect, and cooling water enters from a cooling chamber of body below, pass through two cooling chambers of body top successively after, discharge from another cooling chamber of body below at last.

The utility model compared with prior art, its remarkable advantage is: 1. stationary knife and moving knife are arranged in a crossed manner, are not parallel tangent during shearing, but intersect tangently, therefore, energy consumption is low; 2. the edge of a knife of blade is provided with one deck hard alloy layer, and therefore, the hardness of blade improves greatly, and big leap ahead was sheared the effect of pulverizing and was improved service life; 3. productive rate height, noise is low, can not shut down phenomenon.The utility model is widely used in crushing rubber or plastics.

The utility model is described in further detail below in conjunction with accompanying drawing:
