Description

A kind of three-port type novel circular tup

Technical field

The utility model relates to a kind of three-port type novel circular tups for hammer mill.

Background technique

Hammer mill is lime stone fine crushing in the industrial departments such as metallurgy, building materials, chemical industry and water power, coal or other are medium hard One of the capital equipment of brittle material below spending.It is big with reduction ratio, production capacity is high, advanced structure, reliable performance, work are flat Surely, the features such as low energy consumption and epigranular.Hammer mill is divided to reversible and two kinds of unidirectional type, reversible hammer mill Rotor is reversible, is generally used for fine crushing；The rotor of unidirectional type hammer mill is irreversible, be generally used in it is broken.Machine is using After a period of time, tup work has worn out on one side, and the liner plate and grid section of rotor side also have certain abrasion, at this moment can be with Parking is reversely connected motor, and at this moment rotor reverses, and tup is unworn to reform into working face on one side, and is not worn using the other side Grid section and liner plate.Install a tup can two sides use, reduce the set-up time, improve working efficiency.

Currently available technology hammer head of hammer crusher is divided into a cellular type tup and two cellular type tups according to pin hole quantity.One hole Formula tup one end be pin hole, be hingedly suspended on the pin shaft of rotor block, the other end hit material, when abrasion to a certain extent, i.e., Entirety is scrapped, and stock utilization is low；Two cellular type tups are generally rectangular cross-section, and there is pin hole at both ends, can turn around to use stock utilization It is relatively high.

Utility model content

In view of the shortcomings of the prior art, the utility model provides a kind of higher three-port type novel circular hammers of stock utilization Head.

The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of three-port type novel circular tup, packet Include tup ontology, the tup ontology setting in the form of annular discs, be uniformly distributed along the circumference in the tup ontology 3 round open-works, the circle Castingin steel bushing in open-work；The tup ontology outer circle castingin wear-resisting ring.

Further, the tup body thickness changes between 20-50mm.

Further, the thickness of the steel bushing is equal with tup body thickness.

Further, the steel bushing wall thickness changes between 8-12mm.

Further, the wear-resisting ring wall thickness changes between 15-30mm.

The beneficial effects of the utility model are: three steel bushings are distributed in the form of annular discs since tup is three-port type structure On tup ontology, three steel bushings are sequentially used as pin hole and rotor block pin shaft hinged, when for reversible hammer mill, tup Two sides cambered surface can all hit material, and the cambered surface central angle for participating in strike material every time is generally higher than 45 °, substantially whole less than 90 ° The circumference of a wear-resisting ring has been involved in the strike to material, and stock utilization is high, tup long service life.Tup ontology is using circle Disk-like structure allows to act on the impact force action line on tup essentially by the steel bushing center of circle for being equivalent to center of impact, subtracts Few vibration and noise, Extending Rotor bearing service life；By in steel bushing castingin to middle carbon cast steel substrate, it is possible to prevente effectively from tup The phenomenon that ontology is broken reduces frictional force.The selection of tup ontology has certain toughness and plasticity, intensity and the higher middle carbon of hardness Cast steel, in tup ontology outer circle castingin wear-resisting ring concentric with it, wear-resisting loop material is the high chromium casting that hardness is high, wearability is good Iron, both Material claddings meet job requirement very well, and wear resistance of high-chromium iron is 3 times of existing high manganese steel material or more, Extend tup service life.In addition, tup ontology will not be broken after wear-resisting ring abrasion, new resistance to of castingin on it can be continued Grinding ring, such tup bulk circulation use, and further improve economic benefit.

Detailed description of the invention

The utility model is described in further detail with reference to the accompanying drawings and detailed description.

Fig. 1 is the utility model main view.

Fig. 2 is the utility model top view.

Specific embodiment

As depicted in figs. 1 and 2, a kind of three-port type novel circular tup, including tup ontology 3, the tup ontology 3 is in circle Plate-like is arranged, and be uniformly distributed along the circumference 3 round open-works 4 in the tup ontology 3, castingin steel bushing 2 in the round open-work 4；The tup 3 outer circle castingin wear-resisting ring 1 of ontology.3 thickness of tup ontology changes between 20-50mm.The thickness and tup of the steel bushing 2 3 thickness of ontology is equal.2 wall thickness of steel bushing changes between 8-12mm.By in steel bushing castingin to middle carbon cast steel substrate, Ke Yiyou The phenomenon that effect avoids tup ontology from being broken reduces frictional force.According to finite element analysis and test, determine 1 wall thickness of wear-resisting ring in 15- It is changed between 30mm.

The selection of tup ontology 3 has certain toughness and plasticity, intensity and the higher middle carbon cast steel of hardness, such as ZG 270- 500.When casting, steel bushing 2 is put into evaporative pattern, is poured medium carbon steel solution, makes the two in metallurgical bonding.Then it is poured in its outer circle Rich chromium cast iron solution is infused, makes the two in metallurgical bonding, forms wear-resisting ring.Steel bushing 2 can be cut with steel pipe.

When work, 3 steel bushings are sequentially hinged with rotor block upper pin on tup ontology, get rid of outward under the influence of centrifugal force It opens, the strike implemented to material is broken.When being used for reversible hammer mill, tup two sides cambered surface can all hit material, often The secondary cambered surface central angle for participating in strike material is generally higher than 45 °, and less than 90 °, the circumference of substantially entire wear-resisting ring is involved in The outer ring surface wear of strike to material, such wear-resisting ring is substantially uniform, and stock utilization is high.After wear-resisting ring 1 is worn, hammer Head ontology 3 will not be broken, and can continue the wear-resisting ring that castingin is new on it, such tup ontology 3 can be recycled.

Rich chromium cast iron is the 3rd generation wear-resistant material after potassium steel and the hard IV cast iron of nickel, its hardness can reach 60HRC, The higher M7C3 type carbide of microhardness easy to form in its tissue, the quantity of the type carbide is bigger, and wearability is got over It is good.Wear resistance of high-chromium iron is 3 times of potassium steel or more, but its plasticity is poor, therefore whole tup cannot be cast with rich chromium cast iron, But by its castingin to using middle carbon cast steel in the tup ontology outer circle of matrix, to allow itself and material impacting, advantage is played, from And extend the service life of tup.
