Description
Technical field
The present invention relates to a kind of hammer leaves of pulverizer, especially for use in droplet-shaped pulverizer, atomizer, Verticle grinding
Hammer leaf in machine, dual-rotor crushing machine, multi-cavity grinder, washboard-type pulverizer, pulverizer without sieve etc..
Background technique
The hammer leaf of pulverizer in the prior art is rectangle sheet, sees national standard: SB/T10118-92, hammer leaf powder
One end of broken machine --- hammer leaf, the hammer leaf parent is equipped with pin hole (1), and effect is to be connected by pin rod, screw etc. with rotor,
The other end of hammer leaf is crushed work end face, and operative end surface is made of front end face (3), side end face (2) and lower planes (8).It is logical
Normal hammer leaf parent uses ordinary steel, operative end surface front end face (3) and side end face (2) use the wear-resistant material hardfacings such as tungsten carbide and
At whole surface makees comentation hardening processing, is suitably covered on pin hole (1) surface using small iron plate, covers shape and sees pin hole (1) week
The dotted line on side, to keep pin hole (1) periphery to have toughness without embrittlement.It is symmetrical that pin hole and operative end surface also can be made into both ends
, the other end, which can be replaced, after the abrasion of one end uses again.As the hammer leaf of pulverizer important process component, it is primarily present crushing at present
The short problem of low efficiency, service life.One of reason, common hammer leaf operative end surface are at planar, when thumping material, by material
Before pushing to, generates material and weaken with hammer leaf high-speed motion in the same direction in the material ring of the sieve inner cavity of pulverizer formation rotation
The knocking speed difference of subsequent hammer leaf and material, reduces crush efficiency, while sieve pore is in normal direction, material movement is
Tangential direction, also the discharging ability of unfavorable pulverizer；Second is that frontal impact of the common hammer leaf operative end surface long-time by material,
It is easy to happen the phenomenon that tungsten carbide fine grained falls off.Therefore, the hammer leaf of pulverizer in crush efficiency and uses the longevity for a long time
Great breakthrough is difficult in life.
Summary of the invention
It is an object of the present invention to provide a kind of hammer leaves of pulverizer that can be improved crush efficiency and prolong the service life.
The inspiration of the technical program, the mussel of cobble and Haihe River in riverbed, all stones are big in 1 years
Most stable of shape is formed after the stream erosive wear of Haihe River, is exactly oval, the Ha Bei in Haihe River, object is selected unexpectedly in day, with most economical raw material,
Most firm house is built, it is characterized in that fan-shaped and fillet.In conjunction with this case: a kind of hammer leaf of pulverizer, the hammer including sheet
One end of piece parent, the hammer leaf parent is equipped with pin hole (1), 2 right angles of another working end of hammer leaf parent, i.e. side end face
(2) and front end face (3), equal heap are welded with wear-resistant material, and the wear-resistant material is diamondite, its main feature is that in hammer leaf parent
2 right angles of another working end, symmetrically remove right angle, are processed into cant end face (4), cant end face (4) and side end face (2)
Included angle A is between 30-60 degree, and coupled front end face (3) and side end face (2) is together, build-up wear-resistant material, forms fan
Shape end face (5), fan-shaped end face (5) outermost end width E are greater than hammer leaf width F, E > F, and the lower planes of hammer leaf adjacent thereto
(8), three faces are connected built-up welding, are formed ball head (6), make the cross-sectional view of the side of hammer leaf, at there is the match of ball head (6) rod-shaped,
The diameter of ball head (6) is greater than 1.5 times of hammer leaf thickness, D >=1.5B.This case can also be by 2 of the working end of hammer leaf parent
Right angle prescinds right angle, is made stairstepping end face (9), increases built-up welding contact area.It can also be by 2 of the working end of hammer leaf parent
Side end face (2), which is made, tiltedly puts the first edge on a knife or a pair of scissors, and crush efficiency can be increased by putting the first edge on a knife or a pair of scissors.It can also be by the front end face (3) of the working end of hammer leaf parent
Flute profile is made, increases wear-resistant material.The fan-shaped end face (5) and sieve surface of neoteric hammer leaf form new hammer-screen ciearance, gap
Descending, when thumping material, the fan-shaped end face (5) of forward hammer leaf can produce the component for pressing to compass screen surface, and material is pushed away
To sieve pore, change sieve pore and the inconsistent phenomenon in material movement direction so that material be easier sieve, and reduce material with
Hammer leaf rotation movement velocity, increase the knocking speed difference of subsequent hammer leaf and material, improve crush efficiency；Meanwhile it fanning
Shape end face (5) shape and ball head (6) reduce material to the frontal impact power of hammer leaf side end face (2), and hammer leaf service life is big
Big to extend, with korneforos cobble, dimensionally stable is extremely abrasive, and with mussel class, in the impact of wave sandstone, object is selected unexpectedly in day, and hundred are smelt
Essence.
