Abstract
The utility model discloses a high efficiency superfine pulverizer for small gravitational material, and consists of a spindle assembly 1, a gear ring and a hammer plate assembly 2, a feeding assembly 3, a machine body assembly 4, a classification and power assembly, etc. The feeding assembly 3, which is positioned below the gear ring and the hammer plate assembly 2, is an air flow channel; wherein, the air flow channel comprises a feeding pipe 3-1 which is provided with a feed inlet and is connected with a ventilation hole 3-2; a hammer plate 2-1 is downwards provided with a plurality of lower hammer heads 2-3 which are coaxially arranged with upper hammer heads 2-2. The upper and the lower hammers and the gear ring 2-4 form a vertical pulverizing pair, with clearance being of 8 to 12 millimeters; the upper end surface of the lower seat of the machine body assemble 4 is provided with a gear ring 2-5 which forms a horizontal pulverizing pair with the lower end surfaces of the lower hammer heads 2-3, with the clearance being of 10 to 20 millimeters. When in work, the material with small specific gravity, under the suction force effect of the air flow of the fan, and after a feeding pipe 3-1 and a ventilation hole 3-2, enters the horizontal pulverizing pair and the vertical pulverizing pair for sufficient pulverizing.
Description
One, technical field
The utility model relates to general machinery equipment, particularly ultra-fine impact type atomizer.
Two, background technology
Existing ultra-fine impact type machinery atomizer is made up of eight big assemblies such as base, main shaft, classification, feed, gear ring and hammer dish, body, power, the complete pulverizing units of composition such as it and cyclone separator, deduster, blower fan; The feed assembly is an auger conveyor, it is arranged in gear ring and the middle top of hammering disc assembly into shape, to pulverizing the bigger mineral material of proportion, this layout is rational, but when pulverizing rice husk, white carbon, activated carbon powder, some proportions such as the ripe starch of sheet are little, during the big material of specific volume, there are two open defects in this layout, the one, when material enters the body crushing chamber, because the air-flow that the system fan exhausting forms from bottom to top, light material directly is sucked away without the pulverizing of gear ring and hammer dish, the 2nd, the crushing auxiliary that gear ring and hammer dish are formed, the short about 50-60mm of its effective operation interval, material is promptly taken away by air-flow without fully pulverizing, and finally causes product granularity thick (greater than 18 μ m), ineffective low yield low-quality situation.
Three, summary of the invention
The utility model will provide a kind of can make little of the efficient ultrafine crusher of heavy material that little proportion, big specific volume material are fully pulverized, grinding particle size is thin, efficient is high, when pulverizing little proportion, big specific volume material to solve existing pulverizer grinding particle size thick, yield poorly, operating efficiency is low even the problem that can't pulverize.
Technical solution of the present utility model is on the existing pulverizer basis of being made up of assemblies such as base, main shaft, classification, feed, gear ring and hammer dish, body, power, the screw feeder conveyer of top in the cancellation hammer dish, the ventilating opening that changes into following of body connects charge pipe, and the air-flow suction that utilizes blower fan to produce is finished to inhale and sent material to.
Be equipped with at existing pulverizer hammer dish a plurality of on the basis of upper ram, on the hammer dish down with the coaxial lower ram of being furnished with equivalent of upper ram, the vertical crushing auxiliary working depth that tup side and gear ring side are formed is multiplied;
Increase the gear ring height and pulverize effective operation interval to increase to 145-155mm;
The newly-increased ring gear of inner face on following of body, the lower surface of it and lower ram constitutes one group of horizontal crushing auxiliary, and its gap is 10-20mm.
Vertically crushing auxiliary gap that is last lower ram side and gear ring side clearance are 8-12mm.
Adopt the efficient ultrafine crusher of little proportion of above technical scheme, material is all omnidistance by the crushed work interval when pulverizing, thereby is fully pulverized.Product granularity is thin, and fineness is brought up to 6.5-13 μ m, crush efficiency height from original 23-18 μ m.In addition, owing to cancelled the conveying worm feeder of former pulverizer, the air-flow feed that replaces need not to increase power of fan again, has not only simplified device structure, has reduced the device fabrication cost, and power consumption when also having reduced the material pulverizing has reduced product cost.
Four, description of drawings
Fig. 1 is that the utility model is little of the positive cross-sectional schematic of the efficient ultrafine crusher structure of heavy material.
Five, the specific embodiment
The utility model is little to be made up of assemblies such as base main shaft, classification, feed, gear ring and hammer dish, body, power than the efficient ultrafine crusher of heavy material, wherein main shaft assembly 1, gear ring and hammer disc assembly 2, feed assembly 3 and block assembly 4 positions relation are as shown in Figure 1, the ventilating opening 3-2 of 4 times seats of the charge pipe 3-1 of this feed assembly 3 and body docks, court has 8 lower ram 2-3 on hammer dish 2-1, be arranged coaxial with 8 upper ram 2-2, last lower ram is formed vertical crushing auxiliary, the about 10mm in gap with the gear ring 2-4 that is fixed on highly about 150mm on the body 4; Be provided with ring gear 2-5 on the inner face on 4 times seats of body, with the about 15mm in gap, lower surface that hammers 2-3 down into shape, both constitute horizontal crushing auxiliary again.This technical scheme is being cancelled the helical feed feed assembly of former pulverizer above being located in gear ring and the hammer disc assembly 2, adopt the air-flow suction feed that below gear ring and hammer disc assembly 2, produces by blower fan after, need not increase power of fan.During work, little than heavy material under the fan airflow effect, through charge pipe 3-1, ventilating opening 3-2 enter after the pulverizing chamber successively by horizontal crushing auxiliary and vertically crushing auxiliary fully pulverized, under the air-flow suction, enter grader again.
