Description

Multi-roll extruding force adjustable rolling type pellet making machine

The utility model belongs to the compaction type comminutor, and the adjustable compaction type comminutor of multi-roll extruding force especially is applicable to the occasion of chemical fertilizer and other granular material granulation.

Before the utility model is made; the squash type comminutor mainly contains the pair roller type make-up machine both at home and abroad; screw extrusion comminutor and vertical flat-die Squeezinggranulator three classes; especially vertical flat-die Squeezinggranulator; this machine is mainly by roller frame; centrifugal distributing device; running roller; material scraper; template; main shaft; bearing; little axle; big shaft coupling; little shaft coupling; transmission decelerating device and housing; support; motor is formed; roller frame is provided with 4～5 rolling axles; 1 running roller is housed on the every rolling axle; running roller on the roller frame and the gap between the template are fixed in the course of the work; extruding force can not be regulated; centrifugal distributing device is applicable to the granulation of compound fertilizer for the dull and stereotyped distributing device of circle, and these facility have volume little; simple in structure; easy to operate, granulating rate advantages of higher, but cloth narrow range; production capacity is little, and operation is stable inadequately.

Task of the present utility model is the shortcoming that overcomes prior art, provides that a kind of volume is little, simple in structure, easy to operate, granulating rate is high, the cloth wide ranges, the adjustable compaction type comminutor of multi-roll extruding force that production capacity is big, stable.

The compaction type comminutor that the multi-roll extruding force is adjustable; include roller frame 1; centrifugal distributing device 3; running roller 6; material scraper 7; template 8; main shaft 9; bearing 10; 18; little axle 14; big shaft coupling 12; little shaft coupling 16; transmission decelerating device 15 and housing 11; support 13 and motor; mainly by clamp nut 2; extruding force regulating spring 5 and small takeover 4; 17 compositions of big adapter; motor is by the one-level decelerator; be connected with transmission decelerating device 15 by little shaft coupling 16; little axle 14 matches with transmission decelerating device 15; and by bearing 18 supports; little axle 14 links to each other by big shaft coupling 12 with main shaft 9; main shaft 9 is supported by bearing 10; match with roller frame 1 in main shaft 9 tops; on the every rolling axle that roller frame 1 is provided with 2 running rollers 6 are housed; each running roller 6 is cooperated with the rolling axle of roller frame 1 by bearing separately; circular template 8 devices under the running roller 6 are on main shaft 9; these template 8 outsides are articulated on the housing 11; have material grain moulding hole on the template 8; material scraper 7 is arranged on the roller frame 1; extruding force regulating spring 5 is enclosed within on the main shaft 9; and directly be pressed on the roller frame 1; clamp nut 2 is equipped with in extruding force regulating spring 5 tops; centrifugal distributing device 3 is in main shaft 9 end bolting; the gear type that is shaped as of centrifugal distributing device 3 is justified dull and stereotyped; small takeover 4 is located at the top of housing 11; big adapter 17 is arranged on the middle part of housing 11, and support 13 is connected with housing 11 usefulness flanges.Tooth of offering on centrifugal distributing device 3 circumference of gear type circle flat board and groove arc length equate and evenly distribute along circumference.

Operation principle of the present utility model is that motor reaches the purpose that turns to deceleration by one-level reduction box and transmission decelerating device 15, when main shaft 9 during with the design speed transmission, driving roller frame 1 rotates, rotation is done in running roller 6 dependence that are provided with on the rolling axle of this roller frame 1 and the friction between the powder on the template 8, simultaneously one deck powder on the template 8 is clamp-oned in template 8 holes, because centrifugal distributing device 3 adopts the dull and stereotyped distributing device of gear type circle, centrifugal distributing device 3 is thrown on the template 8 of broad with main shaft 9 turning handle powders, scraped gently by material scraper 7, make the bed of material thickness on the template 8 even, roll through running roller 6 then, constantly material is clamp-oned in template 8 holes, the cylindric billot that comes out from bottom, template 8 hole, cut into short cylinder material grain with the cutter that rotates with the axis, this material grain drops on the reclaiming plate of rotation, and under centrifugal action, the material grain is flowed out by the outlet tangent line of housing 11; In whole granulation process, when the thickness of feed layer on the template 8 had fluctuation, extruding force regulating spring 5 can be regulated the required extruding force of granulation automatically, made to operate steadily, and the compression strength of material grain is even; 2 running rollers 6 that are provided with on the every rolling axle of roller frame 1 are along with the rotation of roller frame 1, because each running roller 6 is cooperated with the rolling axle of roller frame 1 by bearing separately, so on the rolling axle of roller frame 1, the angular speed of its inboard running roller 6 that is provided with is lower than the angular speed of inboard running roller 6, reduced the poor of each running roller 6 interior out conductor speed, thereby reduced the slippage of each running roller 6 relative template 8, frictional heating amount between powder and the running roller 6 is reduced, the warp-wise length that makes 2 running rollers 6 roll increases, and causes the production capacity of comminutor to improve; The small takeover 4 that is provided with on housing 11 tops is mainly used in gets rid of the gas of extruding in the powder, and the big adapter 17 that is provided with at housing 11 middle parts is as the passage that cools off air and discharge the gas that the material grain volatilizes.

Comminutor of the present utility model compared with prior art, volume is little, and is simple in structure, easy to operate; the granulating rate height, the compression strength of material grain is even, the cloth wide ranges, production capacity is big; extruding force is adjustable, and is stable, can be widely used in the granulation of chemical fertilizer and other granular material.
