Ultra tiny pulverizing machine

The utility model relates to a kind of size reduction machinery, specifically is a kind of ultra tiny pulverizing machine.

In existing similar machines, 92239824.0) and the high accuracy Cone crusher (patent No.: 94209318.6) done many improvement, remedied some shortcomings, the Cone crusher (patent No.: although performance improves a lot, so still have following many disadvantages, influence the quality of converted products; 1, pulverize sticky material (as contain solid additive lubricating oil, paint, printing ink, coating, contain sugared material etc.) time charging not smooth, efficient is not high; 2, particle size uniformity is undesirable, even the good material of rigidity, its particle diameter of mill back is greater than stator and the rotor higher proportion that still has to the flour milling gap width; 3, the accumulation of error causes having decided and rotor eccentricity after the general assembly, and is inhomogeneous to the flour milling gap; 4, batch mixing pan is connected with main shaft with screw thread, dismounting inconvenience, and need specific purpose tool, and also need knock sometimes, cause that easily the main shaft precision reduces; 5, the main shaft supporting bearing is a hollow garden post roller bearing, and valency is expensive, and is fragile, temperature rise, and it is long to give the heat run time, and powder particle diameter is seemed uneconomical greater than the ultra tiny pulverizing of 5 μ M; Temperature rise when 6, main shaft runs up has reduced the service life of bearing and the life cycle of lubricating oil; 7, main shaft is connected with key with motor shaft, and key main shaft when transmitting moment of torsion is subjected to a radial load, and the restriction because of bearing rigidity causes spindle swing, has reduced running accuracy; 8, needs are pushed and roll the material of processing, crushing effect is bad.

The utility model is the modified that improves of Cone crusher and high accuracy Cone crusher, a kind of ultra tiny pulverizing machine that provides is provided, limited diameter section, spring mechanism, ball fairlead, cooling body, yielding coupling by sealing barrel, stator and rotor wait the defective that overcomes existing pulverizer, to reach desirable crushing effect.

Embodiment of the present utility model is as follows: ultra tiny pulverizing machine comprises housing 10, stator 4, rotor 5, batch mixing pan 9, main shaft 15, motor shaft 18, bearing turnover barrel and adjusting part etc., feeding cylinder is sealing barrel 1, stator 4 lower ends embed stator limited diameter section 6, rotor 5 lower ends embed rotor limited diameter section 7, stator 4 and rotor 5 install the back and add between to flour milling and grind the back agent and grind, batch mixing pan 9 and main shaft 15 are for being slidingly matched, main shaft 15 usefulness angular contact bearings support, spring mechanism 11 is equipped with in lower bearing 13 upper ends, between the bearing bore inwall of lower bearing 13 outer shrouds and housing 10 ball fairlead 12 is housed, seal cover assembly 14 is equipped with in housing 10 inner chamber bottoms, shaft coupling cover 16 is equipped with in main shaft 15 lower ends, wherein is equipped with rubber column 17.

Material is in the seal cavity of being made up of sealing barrel 1, bolt 2, sealing ring 3, stator 4, rotor 5 to before the outflow of flour milling gap, and sealing barrel 1 top is provided with inflation and chews, and fills during work with Compressed Gas, presses on charge level, and realization pressure is failed material.

The limited diameter section 6 inner surface epimeres of stator 4 have tooth, and tooth bottom line and inner conical surface have an inclination angle, and the bottom is the smooth conical surface, and tapering is consistent with the inner conical surface of stator 4, and the outer surface of rotor 5 limited diameter sections 7 is the smooth conical surface, and tapering is consistent with the male cone (strobilus masculinus) of rotor 5.The male cone (strobilus masculinus) tapering of the inner conical surface of stator 4 and rotor 5 is identical, constitutes flour milling.After to the flour milling wearing and tearing, stator 4 moves down, and keeps the required gap of flour milling.

After batch mixing pan 9 was contained on the main shaft 15, with main shaft shaft shoulder location, batch mixing pan 11 upper surface outer rims had cushion rubber 8, and cushion rubber 8 is compressed by rotor 5 during the normal position.

Produce when spring mechanism 11 is installed and give compression, its pushed down lower bearing 13 of assembling back makes up and down two bearings form axial level pressure and gives tightly, to eliminate the axial and radial clearance of two bearings.

The 12 usefulness interference of ball fairlead are installed, and can only move axially under spring mechanism 11 effects to guarantee lower bearing 13.Seal cover assembly 14 makes the annular chamber bottom of housing 10 become a sealing radiator, be equipped with on the housing 10 into water connect chew 19 and draining connect and chew 20, during work by the water cooling bearing that circulates.Shaft coupling cover 16 and glue post 17 constitute a yielding coupling, make main shaft 15 and motor shaft 18 become resilient connection.

With practical high accuracy Cone crusher relatively, the utility model has following advantage accordingly because of having made the many places substantial improvements: 1, sealing pressurization feeding, accelerate material especially sticky material to the flow velocity between flour milling, thereby improved productivity ratio; 2, stator and rotor are set up the limited diameter section, two limited diameter section materials are identical, processing method is identical, course of work wear extent equates, so can guarantee reliably in total life cycle that its smooth surface does not misplace or magnitude of misalignment in allowed limits, adjust two limited diameter section shiny surface gaps, make greater than pulverizing to require the material of particle diameter not discharge, guaranteed the uniformity of comminuting matter particle diameter; 3, after general assembly is finished, add grinding agent between to flour milling and grind, select suitable grinding agent and rotor speed for use, can eliminate the stator that causes because of the foozle accumulation and the off-centre between rotor,, guarantee to pulverize quality to realize the uniformity to the flour milling gap; 4, batch mixing pan and main shaft be for being slidingly matched, shaft shoulder location, and when rotor rotation, the frictional force of cushion rubber makes batch mixing pan obtain moment of torsion, can operate as normal, easy accessibility influences the running accuracy of main shaft again; 5, main shaft supports with two angular contact bearings, under the effect of spring mechanism, the axial level pressure of two bearings is given tightly, not axially and radial clearance, and do not make the thermal stretching of main shaft can only be downward, level pressure be given tightly and can accurately and easily be controlled on the smaller value, make the heat run time of giving of main shaft and bearing short, temperature rise is little, and reduces even eliminated the influence of adjusting to the flour milling gap, has improved economy; 6, the ball fairlead of interference installation, eliminate the radial clearance of bearing, and have definite value to give tight power, when its excess-three of two bearings installed surface is matched into the cooperation of no gap by deviate, reduce to organize separately part foozle and rigging error to the influence of main axis rotation precision, improved the main axis rotation precision; 7, because water circulation cooling bearing both had been beneficial to the raising speed of mainshaft, can prolong bearing service life and lubricating oil life cycle again; 8, the employing of yielding coupling makes main shaft stressed evenly, and force in radial can be ignored, and has further improved the main axis rotation precision; 9, adopt the material that abrasive material stator and rotor can be pulverized preferably needs to push and roll pulverizing, remedied the deficiency of original structure.
