Abstract
The utility model relates to an axial feed hammer frame plate device for self-feeding disintegrator, which is composed of a front hammer frame plate, fan blades, a shaft sleeve and a back hammer frame plate. The fan blades are installed between the front hammer frame plate and the back hammer frame plate, and the flanks of the fan blades and the front and the back hammer frame plates are matched in a zero clearance mode. Thereby, the utility model has the advantages of large air quantity, reliable material lift, low energy consumption, reasonable and compact structure, etc.
Description
The utility model relates to the hammer frame plate device of the self-priming pulverizer of a kind of axial admission.It is contained in the casing of pulverizer and is fastened on the main shaft of pulverizer.
The feeding manner of pulverizer has radially two kinds of feed types and axial admission formula, and material is promoted in the feed hopper of pulverizer by artificial or elevator.My institute has designed the self-priming pulverizer of a kind of axial admission in 1988, between the forward and backward hammer frame plate of pulverizer, load onto fan blade, they are contained on the main shaft of pulverizer together, and with main shaft rotation at a high speed together, form negative pressure around the axle center of pulverizer, material sucks pulverizing chamber hammer leaf interior and that rotated at a high speed and smashes the sieve aperture that the back wind-force that rotation produces with fan blade passes the sieve sheet through being contained in the axial suction tube of pulverizer, falls in the storage bin after the wind dedusting that disappears.Such pulverizer has saved manually to be proposed the heavy work of material together or has saved a mechanical type elevator, and structure is simple, cost is more cheap, and has alleviated certain labour intensity.For convenience and the simplified manufacturing technique that assembles, the side and the rear hammer rack plate of fan blade are fixedly connected, kept certain clearance (1～3 millimeter) between another side of fan blade and the front hammer rack plate, front hammer rack plate relies on the locking nut on the pulverizer main shaft to lock it on the side of axle sleeve (seeing accompanying drawing 3).Through us long-term practice and research repeatedly, this structure has following deficiency: 1) owing between side of fan blade and the front hammer rack plate certain clearance is arranged, during blade working air quantity produce to leak and forms eddy current, has not only wasted energy but also reduced the self-priming charging ability that air quantity has reduced pulverizer; 2) front hammer rack plate only relies on the main shaft upper locking nut to be locked on the main shaft, and the hammer leaf of pulverizer is contained in the symmetrical holes of front and back hammer frame plate with the bearing pin pin, front hammer rack plate is actually cantilever design, it is too thick that the forward and backward hammer frame plate of pulverizer can not be drawn materials by the restriction of structure and weight, thereby easily generation distortion, pulverizer is big more, and the possibility of distortion is big more, and in case distortion is proofreaied and correct certain degree of difficulty is arranged.
The purpose of this utility model is: provide at above-mentioned technical deficiency a kind of power consumption less, compact conformation, carry material hammer frame plate device reliable, easy to maintenance.
Cooperate for tight between the side that the utility model is achieved in that fan blade and the forward and backward hammer frame plate.Be fixedly connected between fan blade and the forward and backward hammer frame plate.Fan blade is radial arrangement or lean forward layout or hypsokinesis layout in the hammer frame plate device.
Description of drawings:
Fig. 1 is the front view of a kind of embodiment of the utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is a side view of prior art.
Now illustrate in detail with regard to structure of the present utility model and operation principle in conjunction with the accompanying drawings:
The utility model is made up of rear hammer rack plate 1, fan blade 2, axle sleeve 3, front hammer rack plate 4, is fixedly connected with rivet 5 between rear hammer rack plate 1 and the axle sleeve 3, and fan blade 2 usefulness rivets 5 are fixedly connected between forward and backward hammer frame plate 4,1.Cooperate for no gap between the side of fan blade 2 and the forward and backward hammer frame plate 4,1 like this.Fan blade arranged radially between the hammer frame plate of front and back, the number of blade are generally 3～6.Front hammer rack plate 4 and axle sleeve 3 adopt the axial location mode to connect, and generally adopt interference fits.The hammer frame plate device that rear hammer rack plate 1, fan blade 2, axle sleeve 3, front hammer rack plate 4 are formed has become an integral body, has formed a frame structure, and intensity greatly improves.This device is inserted in axle sleeve 3 on the main shaft of pulverizer after the pulverizer external mounting finishes, and gets final product with nut locking.During work, pulverizer main shaft rotates at a high speed, the hammer frame plate device is rotation together, form negative pressure state around the axle center of pulverizer immediately, (most of material passes through the kidney shape slotted hole of front hammer rack plate 4 to the material that need pulverize in being contained in the axial suction tube suction pulverizing chamber of pulverizer, between forward and backward hammer frame plate 4,1, throw away), the hammer leaf that is contained in the bearing pin pin immediately on the symmetrical holes 6 of forward and backward hammer frame plate 4,1 smashes.Meeting the powder (filtering through the sieve sheet) of fineness and wind-force that the fan blade rotation produces passes through the sieve aperture that sieves sheet together and falls in the storage bin after the wind dedusting that disappears; The particle that does not reach fineness continues to pulverize in pulverizing chamber, until reach requirement with aforementioned the same fall into storage bin till, whole crushing process is so far finished.
Long when service time, after the wearing and tearing of consumable accessorys such as hammer leaf, fan blade, can integral body take off, integral replacing or removable parts consumable accessory are all very convenient, quick.Sheet 2 can also lean forward between forward and backward hammer frame plate 4,1 and arrange or hypsokinesis arrangement (direction of forward and backward relatively hammer frame plate rotation) during fan.Leaning forward, it is bigger to arrange the blast that produces, and it is also bigger to consume energy; It is less that the blast that produces is arranged in hypsokinesis, and it is also less to consume energy; Arranged radially is between the two aforementioned.According to the different individual characteies of comminuting matter and the different requirements of smashing fineness, use flexibly.When the smaller or forward and backward hammer frame plate of pulverizer is drawn materials when thick, front hammer rack plate 1 can be fixedly connected without rivet with fan blade 2, front hammer rack plate is contained on the pulverizer main shaft and relies on the locking nut on the main shaft to lock, thereby front hammer rack plate 1 is close on the side of fan blade 2.Secondary or the welding replacement of the also available bolt of rivet 5.
Because the utility model is the general frame structure, fan blade and forward and backward hammer frame plate Between adopt gapless to cooperate, thereby have that power consumption is little, air quantity is big, compact conformation is reasonable, Carry and expect the advantages such as reliable, easy to maintenance.
