Description

Vertical ultrafine disintegrator

Technical field:

The utility model relates to vertical ultrafine disintegrator.Be widely used in the pulverizing of various Chinese herbal medicines and fibroid, heat sensitive material.Belong to the size reduction machinery technical field.

Background technology:

Be used to pulverize the pulverizer of Chinese herbal medicine etc. at present, major part depends on vertical atomizer, and this machine is made up of pulverizing chamber, cutterhead, square cutter piece, grading wheel, gear ring, driving main transmission and classification transmission etc.There is feed mechanism the pulverizing chamber side, and discharging is collected the pulse bag type dust collector dedusting by top air-introduced machine and cyclone separator.Feed mechanism is sent material into pulverizing chamber, cutterhead through rotating at a high speed, the collision between cutter piece and fixed gear ring is sheared, and particle is split into micro mist rapidly, because the effect of negative pressure, material enters grading wheel by baffle liner, carries out classification, and the powder of classification will pass through from the gap between the blade of grading wheel, because powder is subjected to the effect of three power simultaneously, there is grading wheel to rotate the centrifugal force of generation at a high speed, the centripetal force that the gravity of powder self and negative-pressure air-flow produce.Have only the micro mist grain of the centripetal force of negative pressure greater than centrifugal force and self gravitation, could enter cyclonic separation by grading wheel smoothly collects, the effect because of its suffered centrifugal force, gravity that powder is big is thrown to baffle liner and enters pulverizing chamber and pulverize, the size of material particular diameter, be to change with the grading wheel change in rotational speed, rotating speed is high more, and the powder of classification is just more little, therefore, levelling grading wheel rotating speed is the decisive factor of control powder thickness.This machine has the following disadvantages:

1, main shaft and classification axle are driven by same transmission mechanism, and the grading wheel rotating speed can not free speed governing, regulate the fineness ability that material is pulverized;

2, the graded blade of grading wheel is the column layout, the particle diameter skewness, and grading effect is undesirable;

3, square cutter piece has only two cutting edges, and area is little, and the bump that material is subjected to, the opportunity of shearing friction are little;

4, main frame does not have cooling device, and slow to the heat heat radiation that produces in the high speed crushing process, machine cavity temperature height does not fit into the pulverizing of heat sensitive material, and material time of staying in the machine chamber is long, and the material temperature is high, has reduced smashing capability and output.

Summary of the invention:

The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of smashing capability good, and grading effect is good, the vertical ultrafine disintegrator that energy consumption is low.

The purpose of this utility model is achieved in that a kind of vertical ultrafine disintegrator, comprise casing, main shaft, cutter head assembly, gear ring, baffle liner, grading wheel and classification axle, it is characterized in that: on described casing divides, lower casing two parts, the lower casing top is equipped with top cover, insert in the lower casing top cover bottom, in the middle of the upper casing lower end is inserted in the lower casing, flange with middle tape spool bearing between upper casing bottom outer wall and the top cover top end face is connected, lower casing top one side is provided with charging aperture, bottom one side is provided with air inlet, upper casing top one side is provided with outlet, lower casing top middle device has baffle liner, lower casing bottom middle device has main bearing seat, main shaft device is on main bearing seat, its lower end links to each other with spindle drive, end device cutter head assembly on the main shaft, cutter head assembly places the baffle liner periphery, with put gear ring again on the lower casing internal face at cutter head assembly opposite position place, gear ring matches with cutter head assembly, upper casing top device classification bearing block, classification axle upper unit is on the classification bearing block, the upper end links to each other with the classification shaft transmission, place in the upper casing in the middle of the classification axle, expose in the middle of the baffle liner on upper casing insertion lower casing top the bottom, and grading wheel is installed on classification axle lower end.

The utility model spindle drive drives the relative pulverization with gear ring of cutter head assembly by the bottom spindle drive; The classification axle drives the grading wheel rotation by top classification shaft transmission and makes grading; rotating speed height can free step-less adjustment; the fineness that material is pulverized can be conveniently determined,, the purpose of regulating powder granularity can be realized not shutting down by the rotating speed of adjusting grading wheel and the size of negative-pressure air-flow suction air volume.When equipment operation, air-flow is introduced from air inlet and is entered pulverizing chamber by the cutterhead crest clearance, material is entered through pulverizing chamber and air-flow mixed flow by charging aperture, material through pulverizing chamber passes through baffle liner, enter grading wheel, classifiedly take turns qualified classified wheel of particle diameter of screening and enter cyclone collector, undesirable particle diameter drops down onto cutterhead with grading wheel outside and proceeds to pulverize again, so go round and begin again, reach and enter cyclone separator after the requirement and collect.The classification axle is the flange seat bearing that cantilever beam adopts middle tape spool bearing, plays supporting and air-inducing passage effect.Outlet is arranged at grading wheel top makes stock grading smooth and easy, and grading effect is good.

The utility model vertical ultrafine disintegrator, the graded blade of described grading wheel is skewed distribution, can the thinner particle of classification, particle diameter is evenly distributed, and grading effect is good.

The utility model vertical ultrafine disintegrator, the blade of described cutter head assembly have step multitool cutting edge.Since blade multiple-cutting-edge mouth, bump, shearing, friction, and the chance that material is subjected to is many, great efforts.

The utility model vertical ultrafine disintegrator, adopt casing inner wall that the water cooling spacer is set, the water cooling spacer is set in the baffle liner, and the water cooling spacer is set in the top cover, the machine cavity temperature of making is subjected to abundant cooling, charging aperture and air inlet, because the gravitation of air inducing, produce the effect of negative pressure in the machine chamber, air-flow is taken away owing to pulverize the fricative heat of bump, raises so temperature is difficult in the machine chamber, can further cool off the heat that produces in the crushing process, casing, baffle liner, top cover contacts the temperature rapid heat dissipation with material, it is low to pulverize temperature, therefore is specially adapted to the pulverizing of heat sensitive material.
