Description

A kind of diamond shape tup

Technical field

The utility model relates to a kind of diamond shape tups for reversible disintegrating machine.

Background technique

Currently, to the broken generally broken using hammer mill or ring hammer type 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 until being crushed to required discharging-material size finally by sieve plate Outside machine.Tup is the mostly important workpiece of hammer mill.Wherein the quality, shape and material of tup decide that hammer is broken The production capacity of broken machine, the size of tup kinetic energy to the weight of tup be it is directly proportional, 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 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 cover on pin shaft. Generally use the tup quality of broken one ton of supplies consumption as the index for measuring stock utilization.Hit the tup end mill of material Entire tup is scrapped after damage, stock utilization is low, at high cost.Hammer mill is divided to reversible and two kinds of 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, is generally used for It is broken.In use for some time, at this moment having worn out on one side for tup work can stop and motor is reversely connected machine, rotor It reverses, tup is unworn to reform into working face on one side.Install a tup can two sides use, reduce the set-up time, improve work Make efficiency, but the problem that existing tup is short there are still service life.

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 simultaneously from ring hammer, at high speed Ground rushes at crushing shell, is crushed for the second time, then falls on sieve plate, shearing, extruding, grinding and the material hammered into shape by ring 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 will lead to be broken to a certain extent.After fracture Crusher chamber is fallen into, other components can be damaged.It is generally only used for the material of the softs such as break up coal, is limited its application, but Advantage is that structure is simple, and low energy consumption.

Utility model content

The utility model is in view of the deficienciess of the prior art, provide a kind of different from hammer mill rectangle tup and ring The diamond shape tup of hammer mill top fuller.

The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of diamond shape tup, including hammer body, it is described Hammer body assumes 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 The hinged circle open-work of pin shaft.

Further, the wear-resistant block is in lonely shape structure setting.

Further, the hammer body thickness is 0.25-0.35 times of diamond shape side length.

Further, the loss of weight bore dia is 0.5-0.6 times of diamond shape side length.

Further, the round open-work diameter is 0.24-0.26 times of loss of weight bore dia.

The utility model beneficial effect is that circle open-work is inserted in passing on the high-speed rotating pin shaft of daughter, in centrifugal force Effect is lower to form strike torque, and the top and two sides of quadrangle become the scope of attack, be crushed to material, 4 round open-works are sequentially Complete 4 working cycles.Hammer body uses potassium steel, and is primarily involved in resistance to the top castingin rich chromium cast iron of the quadrangle of material pounding Abrading block extends tup service life, and guarantee that tup will not wear and rupture.The strike torque of the utility model is close to hammer Grinder hammerhead, but it is greater than the top fuller of ring hammer crusher, strike torque is big, and strike effect is good.For the broken of same specification The tup quality of machine, the utility model is less than hammer head of hammer crusher, and greater than the top fuller of ring hammer crusher, but service life is 4 times or more of hammer head of hammer crusher are 8 times of circular hammer of annular hammer type crusher or more.

Detailed description of the invention

With reference to the accompanying drawing and embodiment the utility model is described in further detail.

Fig. 1 is the utility model structural front view.

Fig. 2 is the utility model structure top view.

Specific embodiment

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 pin shaft.The wear-resistant block 4 in lonely shape structure setting.

Pass through finite element analysis, optimization design geometric parameter are as follows: hammer body thickness is 0.25-0.35 times of diamond shape side length, is subtracted Repeated hole diameter is 0.5-0.6 times of diamond shape side length, 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 pin shaft 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 be set in technical requirements) 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 guarantee that tup will not wear and rupture.Strike torque is impact force multiplied by pin shaft axis Distance, strike torque it is bigger, strike effect is better.The strike torque of the utility model close to hammer head of hammer crusher, but Greater than the top fuller of ring hammer crusher.For the crusher of same specification, the tup quality of the utility model is less than hammer mill Tup, greater than the top fuller of ring hammer crusher, but service life is 4 times of hammer head of hammer crusher or more, is that ring hammer type is broken 8 times or more of machine top fuller.Reversible disintegrating machine can be with positive and negative rotation, and 4 side striking probabilities are identical, i.e. uniform wear, material benefit With rate height.

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 the rich chromium cast iron of high rigidity, and rich chromium cast iron is the 3rd generation wear-resisting material after potassium steel and the hard IV cast iron of nickel Material, its hardness can reach 60HRC, the higher M7C3 type carbide of microhardness easy to form in tissue, the type carbonization The quantity of object is bigger, and wearability is better.Wear resistance of high-chromium iron is about 3 times of potassium steel, but its plasticity is poor, therefore cannot It is excellent with high road iron casting entirety tup, but by its castingin to using potassium steel on the tup of matrix, to allow itself and material impacting Point is played, to extend the service life of tup.
