Abstract
The utility model discloses a scraper fixed structure for granulator, scraper vertical location axle has, the epaxial vertical location bearing that sets up of every scraper vertical location, be provided with scraper radical location gear between retaining ring and the ring mould, scraper radical location gear is with the direct -geared of scraper electric machine drive gear and on same horizontal line, scraper electric machine drive gear links to each other with the motor shaft, scraper radical location gear drives the scraper and crosses the cab apron transmission, thereby it rotates around granulator ring mold shaft line to drive the scraper, scraper radical location gear top is provided with radical location axle and radical location bearing, thereby it is good to have designed a sealing performance, the transmission is convenient, all fix the scraper fixed structure that stabilizes on radial and the axial direction of scraper.
Description
Technical field
The utility model relates to a kind of granulation field of mechanical technique, particularly relates to a kind of granulator scraper fixed structure.
Background technology
The granulation mode of current granulator has screw extrusion, piston punching press, the extruding of ring mould and roll extrusion several.Typical equipment is the granulator adopting ring mould extruding granulation mode; the structure of this granulator is; two pressure rollers are set in ring mould; during work; wedge shaped squeeze room (portion) is formed at ring mould and pressure roller; by relatively rotating of ring mould and pressure roller, the material of wedge shaped squeeze indoor is extruded inner ring mould by powerful active force, completes granulation.
In addition, in the prior art, the scraper of some granulators is arranged on roller seat cover plate, see utility model (CN201445943U), scraper is the charge bar relying on the power cut provided of mair motor to extrude from granulation hole, and in such situation, granulator operating efficiency is not high; Some granulators connect the direct frame of travelling gear of scraper above ring mould, thus affect sealing; In the middle of the travelling gear clamping gear ring of some granulator scrapers, thus cause gear ring thicker; Fixing firm not in radial and axial both direction of the scraper of some granulators, see patent of invention (CN104474974A); In order to solve the problem, the utility model devises that a kind of good seal performance, transmission are convenient, firm scraper fixed structure is all fixed in the radial and axial direction of scraper.
Summary of the invention
The purpose of this utility model is to overcome prior art deficiency, and the utility model devises that a kind of good seal performance, transmission are convenient, firm scraper fixed structure is all fixed in the radial and axial direction of scraper.
In order to achieve the above object, the technical solution of the utility model is such: a kind of scraper fixed structure for granulator, it is characterized in that: the lower end peripheral of granulator feeding bucket 6 has the shrouding 7 extending to back-up ring 12, scraper drive motors is fixed on shrouding 7, multiple scraper perpendicular positioning axle 10 is fixed with in back-up ring 12 inner circumferential, each scraper perpendicular positioning axle 10 arranges perpendicular positioning bearing 14, perpendicular positioning bearing 14 is fixed on back-up ring shell, scraper radial location gear 9 is provided with between back-up ring 12 and ring mould, scraper radial location gear 9 directly engages with scraper motor driven wheel 8 and in the same horizontal line, scraper motor driven wheel 8 is connected with motor shaft, scraper radial location gear 9 drives scraper rebound 11 transmission, thus drive scraper to rotate around granulator ring mold shaft line, radial location axle 13 and radial location bearing 15 is provided with above scraper radial location gear 9.
Gear of the present utility model and gear ring adopt laser cutting, and blade thickness controls in 1.5mm, and the path of contact upper blade plane that the edge of a knife is positioned at pressure roller and ring mould upwarps 3 ~ 15 degree of angles in pressure roller ring mould field of conjugate action tangent line.
Preferably; multiple cutter is comprised according to the granulator of first aspect of the present utility model; usually 4-6 is arranged; according to actual needs also more stage property can be set; multiple cutter is located relative to the outer surface of ring mould, cuts off particle, be arranged on the outer surface of the multiple scrapers in mold cavity close to ring mould for the outer surface from ring mould; to cut off particle from the outer surface of ring mould, discharge mold cavity to allow particle through particle outlet.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of scraper fixed structure of the present utility model;
Be labeled as in figure: 1-doctor assemblies, 2-ring mould, 3-press roll component, 4-dowelled spanner, 5-gland rod, 6-feed hopper, 7-shrouding, 8-scraper motor driven wheel, 9-scraper radial location gear, 10-scraper perpendicular positioning axle, 11-scraper rebound, 12-back-up ring, 13-radial location axle, 14-perpendicular positioning bearing.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
For a scraper fixed structure for granulator, it is characterized in that: the lower end peripheral of granulator feeding bucket 6 has the shrouding 7 extending to back-up ring 12, scraper drive motors is fixed on shrouding 7, multiple scraper perpendicular positioning axle 10 is fixed with in back-up ring 12 inner circumferential, each scraper perpendicular positioning axle 10 arranges perpendicular positioning bearing 14, perpendicular positioning bearing 14 is fixed on back-up ring shell, scraper radial location gear 9 is provided with between back-up ring 12 and ring mould, scraper radial location gear 9 directly engages with scraper motor driven wheel 8 and in the same horizontal line, scraper motor driven wheel 8 is connected with motor shaft, scraper radial location gear 9 drives scraper rebound 11 transmission, thus drive scraper to rotate around granulator ring mold shaft line, radial location axle 13 and radial location bearing 15 is provided with above scraper radial location gear 9.
Preferably, it is 6 that scraper perpendicular positioning axle 10 arranges number, and it is 4 that radial location axle arranges number.
