Abstract
Disclosed is a vertical graded crusher for crushing solid materials. The vertical graded crusher is characterized in that the machine enclosure of a vertical crusher is additionally provided with a grader for replacing the tapered dispersal cylinder of an original vertical crusher, and the inside of the grader is provided with a grader impeller, a returning device and a steering device. The crushing fineness and fineness rate of the crusher can be effectively enhanced by regulating the rotary speed of the grader impeller and the air volume of an induced draught discharge port. With simple structure, reasonable design, convenient manufacture and installation, the utility model can be widely applied to the industries of non-metallic minerals, medicine, chemical industry, foods, etc.
Description
The utility model relates to a kind of solid material disintegrating apparatus, is mainly used in the pulverizing of the various solid materials such as pharmacy, chemical industry, food, feed, mineral products of seven grades of following hardness.
The utility model is to be the improvement of CN89206720.9 disclosed " vertical crusher " patent to the patent No..The sieve spare structure of forming by screen cloth and abrading block that " vertical crusher " adopts that monoblock type mill structure replaces that traditional SD turbine series pulverizer adopted, with the fineness of the size of controlling air quantity with the adjusting crushed material, not only improve the operating efficiency of pulverizer effectively, and greatly prolonged its service life.Yet owing to the smashing fineness of vertical crusher is controlled by the air quantity size, thereby in process of production, after the fineness of crushed material reached certain fineness (350 order), its fineness was difficult to further improve.On the other hand, from the crushed material that the air inducing discharging opening is discharged, some bigger particles that also can mix unavoidably, thus influence its fineness rate.
The utility model is intended to overcome the problems referred to above, and provide a kind of and have higher smashing fineness (more than 350 orders), and the higher vertical classification pulverizer of fineness rate.
For achieving the above object, the utility model has been taked following measure: promptly on the casing of vertical crusher, added a clasfficiator and disperseed tube in order to the taper that replaces former vertical crusher.In clasfficiator, be provided with the clasfficiator impeller, material returning device and steering gear, by the rotating speed of adjusting clasfficiator impeller and the air quantity of air inducing discharging opening, can make by the material that meets the standard fineness after pulverizing through steering gear, sucking-off from the air inducing discharging opening, the material that does not meet the standard fineness reenters the pulverizer mill through material returning device and carries out secondary and pulverize then under the effect of clasfficiator impeller, thereby has improved the smashing fineness and the fineness rate of pulverizer effectively.
Concrete structure of the present utility model is by providing in the accompanying drawing:
Fig. 1 is the structural representation of vertical classification pulverizer.
Be elaborated below in conjunction with accompanying drawing: vertical classification pulverizer is made up of main shaft 1, casing 2, rotor 3, mill 4, clasfficiator 5.Clasfficiator 5 is installed on the casing 2, in the inner chamber of clasfficiator, be provided with a material returning device 6 that is funnel-shaped structure, the shank of material returning device 6 is provided with feed screw structure 7, cone portion is a double-decker, its skin is provided with backwind tube 8, the awl bottom of internal layer is provided with return air hole 9, be provided with a steering gear 11 at the top of clasfficiator shell, steering gear is provided with material sucking port 12 and air inducing discharging opening 13, clasfficiator impeller 10 is fixed on material sucking port 12 places that impeller shaft Shang ， And is installed in steering gear by flange 14.Clasfficiator impeller 10 is driven by motor 16 by the belt on the belt pulley 15.Motor 16 can adopt buncher, diameter that can also be by changing belt pulley or add the rotating speed that speed change gear changes the clasfficiator impeller.
The operation principle and the course of work of vertical classification pulverizer are summarized as follows: the material that will pulverize is put into charging aperture, carries by feed screw structure 7, through material returning device 6 inner chambers, enters the rotor element inner chamber of pulverizer.Under the effect of running up of rotor, material produces strong swirling eddy in the blade of rotor and the slit between the mill, by impacting and grinding, after reaching certain fineness, the material that conforms to the design standard fineness is under the air inducing effect of air inducing discharging opening, classified device is from air inducing discharging opening 13 sucking-offs of steering gear.Do not meet the design standard fineness as yet, bigger material then bumps with the impeller 10 of clasfficiator, produce under the effect of the return air that a downward acceleration And is blown in return air hole, secondary enters the inner chamber of material returning device, at any time the material inner chamber that reenters rotor element is pulverized, (regulate the size that clasfficiator wheel speed And regulates the air quantity of air inducing discharging opening simultaneously, can obtain the material of required fineness), so go round and begin again, can guarantee that the material of sucking-off from the air inducing discharging opening meets design standard fully.
The utility model is simple in structure, reasonable in design, making, easy for installation, owing on the casing of pulverizer, added classification mechanism, thereby make smashing fineness and fineness rate be significantly improved, model machine the results showed, its fineness can be brought up to more than 800 orders, and the fineness rate can reach more than 99.5%.
