Description
Technical field
The utility model is a kind of disintegrating mechanism for micronizer, belongs to the renovation technique for the disintegrating mechanism of micronizer.
Background technology
Micronizer is the widely used pulverizers of industry such as current chemical industry, pharmacy, daily use chemicals, smelting, the granular powder of 15 order left and right can be broken to 80-300 orders, by the classification mechanism in machine, rather than traditional screen cloth, pulverizing, classification are once completed, and grain fineness is adjustable, and production efficiency is higher.Core institution is wherein pulverizing chamber, and the core component in pulverizing chamber is gear ring and cutterhead.Gear ring and cutterhead adopt cast steel manufacture mostly now, gear ring 1 forms a circle by four, the fixing rectangle shear knife 3 of some on cutterhead 2, cutterhead 2 is placed in gear ring 1, cutterhead 2 is concentric with gear ring 1, cutterhead 2, in gear ring 1 high speed rotation, produces larger shearing force between some crushing tooths that gear ring 1 madial wall is provided with and shear knife 3, this shearing force can be shredded material.Between gear ring 1 and shear knife 3, have certain gap, material is just sheared, collides in this gap, is then drawn out of pulverizing chamber and arrives filter chamber, and the qualified material of granularity is from discharge hole for discharge, and underproof material returns to pulverizing chamber again to be continued to pulverize.
Gap minimum between this class pulverizer gear ring 1 and shear knife 3 can be adjusted to 10mm at present, because machining accuracy is poor, cannot turn down again, just may produce collision, badly damaged equipment if less.For general harder, crisp material, can also satisfy the demand in this gap, output also can reach requirement, if but the fiber of material is more, toughness is strong, output just significantly declines, sometimes even cannot reach granularity requirements, and gear ring 1 and shear knife 3 serious wear, greatly shorten service life.
Summary of the invention
The purpose of this utility model is to consider the problems referred to above and a kind of crush efficiency that improves is provided, and can extend the service life of gear ring, thereby reduces the consumption of gear ring and shear knife, reduces the disintegrating mechanism for micronizer of use cost.The utility model is reasonable in design, convenient and practical.
The technical solution of the utility model is: the disintegrating mechanism for micronizer of the present utility model, include gear ring, cutterhead, shear knife, wherein gear ring is the disk-like structure of making hollow cavity, the madial wall of gear ring is provided with some crushing tooths, shear knife is fixed on cutterhead, cutterhead is installed in the set hollow cavity of gear ring, and shear knife and crushing tooth energy relative motion formation shearing force.
Above-mentioned gear ring includes four gear ring sheets, and four gear ring sheets form circular gear ring.
Minimum clearance between above-mentioned shear knife and crushing tooth is for being not more than 5mm.
The tooth depth of the set crushing tooth of above-mentioned gear ring is 10mm.
The knife face width of above-mentioned shear knife is 15mm.
Above-mentioned each shear knife is during over against the set crushing tooth of corresponding gear ring, and the angle forming after the longitudinal centre line of crushing tooth and the longitudinal centre line of shear knife intersect is to take over 5 °, and angle is-5 °.
The utility model compared with prior art, tool has the following advantages: (1) gear ring can coordinate more closely with cutterhead and can not collide with cutterhead, both are reduced in gap, material just can full out be pulverized, the material many for fiber, toughness is strong also can make them reach desired granularity, and output and production efficiency have improved greatly.(2) the knife face width of widening shear knife can improve crush efficiency, extends the service life of shear knife, the tooth depth increase of set crushing tooth on gear ring can be extended to the service life of gear ring, thereby reduces the consumption of gear ring and shear knife, has reduced use cost.(3) inclination angle of change shear knife can make material enter soon in gap, improves crush efficiency.The utility model is that a kind of design is ingenious, function admirable, the convenient and practical disintegrating mechanism for micronizer.

Fig. 3 is the mounting structure figure between prior art shear knife and gear ring.
the specific embodiment
Embodiment:
Structural representation of the present utility model as shown in Figure 1, 2, disintegrating mechanism for micronizer of the present utility model, include gear ring 1, cutterhead 2, shear knife 3, wherein gear ring 1 is for making the disk-like structure of hollow cavity 11, the madial wall of gear ring 1 is provided with some crushing tooths 12, shear knife 3 is fixed on cutterhead 2, and cutterhead 2 is installed in the set hollow cavity 11 of gear ring 1, and shear knife 3 can relative motion form shearing force with crushing tooth 12.
In the present embodiment, above-mentioned gear ring 1 includes four gear ring sheets, and four gear ring sheets form circular gear ring.
In the present embodiment, gear ring 1 is carried out to grinding process, the circle that allows four gear rings form can closely cooperate with cutterhead 2, and the minimum clearance between shear knife 3 and crushing tooth 12 is reduced into and is not more than 5mm by original 10mm.
In the present embodiment, gear ring 1 is carried out to machining, make the tooth depth of the set crushing tooth 12 of above-mentioned gear ring 1 be increased to 10mm by original 7mm.The knife face width of above-mentioned shear knife 3 is increased to 15mm by original 5mm.Above-mentioned shear knife 3 is steel cutter.
Above-mentioned each shear knife 3 is during over against the set crushing tooth 12 of corresponding gear ring 1, and the angle forming after the longitudinal centre line of the longitudinal centre line of crushing tooth 12 and shear knife 3 intersects is to take over 5 °, and angle is-5 °.The inclination angle that is about to shear knife 3 changes, from original take back 5 ° to become take over 5 °.
The utility model is for micronizer successful, and former serving is difficult to the material pulverized and greatly improves as pulverizing output such as the Chinese mahonia in Chinese medicine, golden cypresses, and granularity to reach 120 object percent of pass be 95%, cannot accomplish in the past at all; Yield in unit time has also improved much, take rheum officinale as example, and former output is 0.7T/h, can reach 1.0T/h now; Greatly extended the service life of gear ring and cutter simultaneously, originally will change gear ring or cutter 15 working days, changed again after can reaching now 25 working days, sometimes even can reach 35 and change again.
