Description
Technical field
The present invention relates to a kind of diamond shape tups for reversible disintegrating machine.
Background technology
Currently, generally using hammer mill or ring hammer type broken the broken of the materials such as lime stone, clinker, coke, coal
Machine.
When hammer mill works, motor drives rotor to make high speed rotation, and material uniformly enters in crusher chamber, and high speed is returned
The tup turned impacts, shearing splitting material causes material to be broken, and is discharged finally by sieve plate until being crushed to required discharging-material size
Outside machine.Tup is the mostly important workpiece of hammer mill.The quality, shape and material of wherein tup decide that hammer is broken
The production capacity of broken machine, the size of tup kinetic energy are directly proportional to the weight of tup, and tup is heavier, and kinetic energy is bigger, broken
Efficiency is higher, but the energy consumed is also big.Hammer head of hammer crusher is largely made by potassium steel, but potassium steel
Wear resistence is poor, and service life is short.Hammer-shaped is generally rectangular cross-section or fan-shaped, and material is hit in one end, and one end has hole to be sleeved on axis pin.
It is general to use the index for being crushed the tup quality of one ton of supplies consumption as measurement stock utilization.Hit the tup end mill of material
Entire tup is scrapped after damage, stock utilization is low, of high cost.Hammer mill is divided to two kinds of reversible and unidirectional type, reversible
The rotor of formula hammer mill is reversible, is generally used for fine crushing；The rotor of unidirectional type hammer mill is irreversible, in being generally used for
It is broken.In use for some time, tup work has worn out machine on one side, and at this moment can stop a motor reversal connection, rotor
It reverses, tup is unworn to reform into working face on one side.Tup of installation can two sides use, reduce the set-up time, improve work
Make efficiency, but there are still the short problems of service life for existing tup.
Ring hammer crusher be it is a kind of with ring hammer impact rotor formula crusher, after material enters crusher, first by
It is crushed to being acted on the high-speed rotating ring hammering blow of rotor, pulverized material obtains kinetic energy from ring hammer simultaneously, at high speed
Ground rushes at crushing shell, is crushed for the second time, then falls on sieve plate, is sheared, squeezes by ring hammer, grinding and material
Mutual collision between material is further crushed, and is discharged by sieve pore.Ring hammer is mostly annular shape, also known as top fuller at present.
Top fuller is made by potassium steel, but potassium steel wear resistence is poor, and outer ring surface is line when it hits material as the scope of attack
Contact, since contact area is small, crushing effect is bad, and ring hammers quick abrasion into shape, and abrasion may result in fracture to a certain extent.After fracture
Crusher chamber is fallen into, other parts can be damaged.The general material for being only used for the softs such as break up coal, limits its application, but
Advantage is simple in structure, and low energy consumption.
Invention content
The present invention is in view of the deficienciess of the prior art, provide a kind of different from hammer mill rectangle tup and ring hammer type
The diamond shape tup of crusher top fuller.
The technical solution adopted by the present invention to solve the technical problems is：A kind of diamond shape tup, including hammer body, the hammer body
Assume diamond in shape shape, and the center is equipped with lightening hole, four corners castingin wear-resistant block, and cruciform symmetry line is equipped with 4 and rotor block axis pin
Hinged circle open-work.
Further, the wear-resistant block is in lonely shape structure setting.
Further, the hammer body thickness is 0.25-0.35 times of the diamond shape length of side.
Further, the loss of weight bore dia is 0.5-0.6 times of the diamond shape length of side.
Further, the round open-work diameter is 0.24-0.26 times of loss of weight bore dia.
Present invention has the advantages that being inserted in circle open-work with passing on the high-speed rotating axis pin of daughter, in the effect of centrifugal force
Torque is hit in lower formation, and the top and two sides of quadrangle become the scope of attack, be crushed to material, 4 round open-works sequentially complete 4
A working cycles.Hammer body uses potassium steel, and is primarily involved in the top castingin rich chromium cast iron wear-resistant block to the quadrangle of material pounding,
Tup service life is extended, and ensures that tup will not wear and rupture.The strike torque of the present invention is close to hammer of hammer crusher
Head, but more than the top fuller of ring hammer crusher, strike torque is big, and strike effect is good.For the crusher of same specification, the present invention
Tup quality be less than hammer head of hammer crusher, be more than the top fuller of ring hammer crusher, but service life is hammer of hammer crusher
4 times or more of head, are 8 times of circular hammer of annular hammer type crusher or more.
Description of the drawings
Below in conjunction with the accompanying drawings and embodiment the invention will be further described.
Fig. 1 is structure of the invention front view.
Fig. 2 is structure of the invention vertical view.
Specific implementation mode
As shown in Figs. 1-2, a kind of diamond shape tup, including hammer body 1, the hammer body 1 assume diamond in shape shape, and the center is equipped with loss of weight
Hole 2, four corners castingin wear-resistant block 4, cruciform symmetry line are equipped with 4 circle open-works 3 hinged with rotor block axis pin.The wear-resistant block
4 in lonely shape structure setting.
By finite element analysis, optimization design geometric parameter is：Hammer body thickness is 0.25-0.35 times of the diamond shape length of side, is subtracted
Repeated hole diameter is 0.5-0.6 times of the diamond shape length of side, and circle open-work diameter is 0.24-0.26 times of loss of weight bore dia.
One of circle open-work is inserted in passing on the high-speed rotating axis pin of daughter, forms strike under the influence of centrifugal force
Torque, the top and two sides of the same diagonal line other end become the scope of attack, are crushed to material, reaching the limit of wear (can
To set in being required in technology) after, another circle open-work is changed to, sequentially completes 4 working cycles, 4 sides have to material
Broken probability.Hammer body uses potassium steel, and the top castingin rich chromium cast iron for being primarily involved in four angles being crushed to material is wear-resisting
Block extends tup service life, and ensure that tup will not wear and rupture.It is that impact force is multiplied by axis pin axis to hit torque
Distance, strike torque it is bigger, strike effect is better.The strike torque of the present invention is more than close to hammer head of hammer crusher
The top fuller of ring hammer crusher.For the crusher of same specification, tup quality of the invention is less than hammer head of hammer crusher, is more than
The top fuller of ring hammer crusher, but service life is 4 times of hammer head of hammer crusher or more, is the 8 of circular hammer of annular hammer type crusher
Times or more.Reversible disintegrating machine can be with positive and negative rotation, and 4 side striking probabilities are identical, i.e. uniform wear, and stock utilization is high.
In order to give full play to the advantage of two kinds of materials, hammer body material remains as potassium steel, then resistance in its four corners castingin
Abrading block 4, wear-resistant block 4 are high rigidity Gao Chrome cast irons, and rich chromium cast iron is the 3rd generation wear-resisting material after potassium steel and the hard IV cast irons of nickel
Material, its hardness can reach 60HRC, be easy to form the higher M7C3 types carbide of microhardness, the type carbonization in tissue
The quantity of object is bigger, and wearability is better.Gao Chrome cast iron wearabilities are about 3 times of potassium steel, but its plasticity is poor, therefore cannot
Yong Gao Chrome iron casting entirety tups, but by its castingin to using potassium steel on the tup of matrix, to allow itself and material impacting, it is excellent
Point is played, to extend the service life of tup.
