Description

The fertile rotary drum granulator of a kind of telescopic compound
Technical field
The present invention relates to the fertile rotary drum granulator of a kind of telescopic compound, especially relate to a kind of fertile rotary drum granulator of telescopic compound that is applicable to the granulation of multiple performance pulverulent material.
Background technology
At present domesticly be used to produce the fertile tablets press of compound and mainly contain granulating disc, biaxial granulation machine, rotary drum granulator, Squeezinggranulator.The Squeezinggranulator ubiquity can only carry out the fertile mixing granulation of limited unit, and it is fertile to produce polynary high-quality compound, and energy consumption is high, and output is few; Granulating disc mainly is that the collection of dust and smog is difficult, can not carry out ammonification effectively, also is inconvenient to use steam granulation, can only use the cold water granulation, so energy consumption is also high, output is also little; The biaxial granulation machine is simple in structure, and handiness is big, can adapt to various processing condition, but production product pellet outward appearance is not mellow and full, is difficult for being accepted by peasant household; Rotary drum granulator output is big, and the particle outward appearance is also mellow and full, and shortcoming is that the product yield is low, product hardness is little, and voidage is big, is prone to caking.The rubbing effect that traditional rotary drum granulator, material produce when rotating through rotary drum granulator forms the material bed of a rolling.The squeeze that produces of rolling makes the material that contains certain liquid phase be agglomerated into small-particle, and these small-particles become core, and the powder around adhering to forms bigger particle, and the material packing fraction has only 6%~8%, so yield poorly, balling ratio is not high yet, has only 40%.
Summary of the invention
The object of the invention is exactly to provide a kind of granulating efficient high for the defective that overcomes above-mentioned prior art existence, uniform particles, tight, and energy consumption is low, and equipment manufacturing cost is low, the fertile rotary drum granulator of the telescopic compound that floor space is little.
The object of the invention can be realized through following technical scheme: the fertile rotary drum granulator of a kind of telescopic compound; Comprise support 1, opening for feed 2, support roller 4, frame 8, discharge port 9; It is characterized in that described frame 8 is provided with inner core 7 and is set in outer identical with its turning direction of this inner core 7 but urceolus 6 that rotating speed is different, described inner core 7 outer walls are provided with the arrange granulation rod 3 of configuration of shape in the shape of a spiral; Inner core 7 is arranged on the support 1 through rotating shaft is rotatable; Described urceolus 6 is arranged on the frame 8 through support roller 4, and described urceolus 6 one ends are provided with opening for feed 2, and the other end is provided with discharge port 9;
After material is added by opening for feed 2; Fall on the granulation rod 3 of inner core 7 of rotation; Mixing and rubbing back material through granulation rod 3 fall into urceolus 6 inner bottom parts, and the rubbing effect that produces during through urceolus 6 rotations is fallen on the granulation rod 3 after taking material to certain altitude again again; So circulation, the material that granulation is good after 5-10 minute is discharged through discharge port 9.
The outer wall of described urceolus 6 is provided with gear 5, and urceolus 6 connects second motor 12 through gear 5.
The rotating shaft of described inner core 7 connects first motor 11 through retarding mechanism 10.
The cross section of described granulation rod 3 is circle, flats or trilateral.
The cross section of described granulation rod 3 is circular.
The rotating speed of described inner core 7 is 50~300rpm, and the rotating speed of described urceolus 6 is 5~40rpm.
The rotating speed of described inner core 7 is 100~200rpm, and the rotating speed of described urceolus 6 is 10~30rpm.
Compared with prior art, the telescopic compound fertilizer pelletizing machine of the present invention mainly is in the advantage of utilizing biaxial granulation and drum granulating, the tablets press that unites two into one, i.e. the granulation rod that the spirrillum preparation is arranged of the outside surface of inner core configuration; Existing granulation function has densification again, makes particle mellow and full; Be difficult for crushing, agglomeration resistance, similar biaxial granulation machine; Urceolus is exactly a rotary drum granulator in fact, mainly plays polishing action at this, and is like this that granulation is integrated with polishing.Two each free retarding mechanisms of cylinder link to each other with motor, and rotate in the same way.
Compared with prior art, the advantage that has of the present invention:
1, the powder of available any performance is produced the multicompentnt granular compound fertilizer of the high-efficiency high-quality of any prescription.
2, volume is little, and floor space is little, and easy to operate, working stability, energy consumption is low, investment is low, and the high-efficiency high-quality multicompentnt granular compound that can produce various proportionings is fertile, and specific proportioning can accomplish not have dry, energy-conserving and environment-protective.
3, granulating rate high (more than 95%); The granulating quality is high, uniform particles, tight, difficult crushing, agglomeration resistance.
