Description
Technical field
The present invention relates to a kind of Telescopic compound fertilizer rotary drum granulator, especially relate to a kind of Telescopic compound fertilizer rotary drum granulator that is applicable to the granulation of multiple performance granular material.
Background technology
The domestic comminutor for the production of Chemical Mixed Fertilizer mainly contains granulating disc, biaxial granulation machine, rotary drum granulator, Squeezinggranulator at present.The Squeezinggranulator ubiquity can only carry out the mixing granulation of limited unit fertilizer, can not produce polynary high-quality Chemical Mixed Fertilizer, and energy consumption is high, and output is few; Granulating disc is mainly that the collection of dust and smog is more difficult, can not effectively carry out ammonification, also is inconvenient to use steam granulation, can only use the cold water granulation, therefore energy consumption is also high, output is also little; The biaxial granulation machine is simple in structure, and flexibility is large, can adapt to various process conditions, but production product pellet outward appearance is not mellow and full, is difficult for being accepted by peasant household; Rotary drum granulator output is large, 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 large, easily caking.Traditional rotary drum granulator, the rubbing action produced when material rotates by rotary drum granulator forms a material bed rolled.The extruding force produced of rolling makes the material that contains certain liquid phase be agglomerated into granule, and these granules become core, and the powder around adhering to forms larger particle, and the material pack completeness only has 6%～8%, so yield poorly, balling ratio is not high yet, only has 40%.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of granulating efficiency high in order to overcome the defect that above-mentioned prior art exists, uniform particles, closely, and energy consumption is low, and equipment manufacturing cost is low, the Telescopic compound fertilizer rotary drum granulator that floor space is little.
Purpose of the present invention can be achieved through the following technical solutions: a kind of Telescopic compound fertilizer rotary drum granulator, comprise support 1, charging aperture 2, support roller 4, frame 8, discharging opening 9, it is characterized in that, described frame 8 is provided with inner core 7 and is set in outer identical from its rotation direction of this inner core 7 but urceolus 6 that rotating speed is different, described inner core 7 outer walls are provided with the granulation rod 3 of the configuration of arranging in the shape of a spiral, inner core 7 rotatably is arranged on support 1 by rotating shaft, described urceolus 6 is arranged on frame 8 by support roller 4, described urceolus 6 one ends are provided with charging aperture 2, the other end is provided with discharging opening 9,
After material is added by charging aperture 2, fall on the granulation rod 3 of inner core 7 of rotation, mixing and the rear material of rubbing by granulation rod 3 fall into urceolus 6 inner bottom parts, the rubbing action produced during by urceolus 6 rotation, after again material being taken to certain altitude, again fall on granulation rod 3, so circulation, the material that after 5-10 minute, granulation is good is discharged through discharging opening 9.
The outer wall of described urceolus 6 is provided with gear 5, and urceolus 6 connects the second motor 12 by gear 5.
The rotating shaft of described inner core 7 connects the first motor 11 by reducing gear 10.
The cross section of described granulation rod 3 is circle, flat or triangle.
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, Telescopic compound fertilizer comminutor of the present invention is mainly in the advantage of utilizing biaxial granulation and drum granulating, the comminutor united two into one; it is the granulation rod that the helical form preparation is arranged of the outer surface configuration of inner core; existing granulation function, have again densification, 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 play polishing action at this, like this that granulation and polishing is integrated.Two each free reducing gears of cylinder are connected with motor, and rotating in same direction.
Compared with prior art, the present invention has advantages of:
1, the powder of available any performance is produced the multicompentnt granular Chemical Mixed Fertilizer of the high-efficiency high-quality of any formula.
2, volume is little, and floor space is little, and easy to operate, working stability, energy consumption be low, it is low to invest, and can produce the high-efficiency high-quality multicompentnt granular Chemical Mixed Fertilizer of various proportionings, and specific proportioning can be accomplished without 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.
