Abstract
The utility model discloses a composite roller device of a squirrel-cage crusher. The composite roller device comprises round steel (1), flat steel (2) and composite antifriction metal (3), wherein the round steel (1) is located on two sides of the device, the flat steel (2) is located in the center of the device, the round steel (1) and the flat steel (2) are connected in a welding mode, and the composite antifriction metal (3) is uniformly cast on the surface of the round steel (1) and the flat steel (2). The composite roller device of the squirrel-cage crusher has the characteristics of scientific and reasonable design, long service life, simple structure, high strength, hardness and wearing resistance and the like, is widely suitable for material smashing and blending operation in industries such as chemical engineering, building materials, mines, electric power, metallurgy, grain and the like, and is an ideal product for replacing a roller of the conventional crusher.
Description
Technical field
The utility model relates to industrial trade crushing mechanism field, is exactly the compound rod device that hits of a kind of cage mill concretely.
Background technology
At present, cage mill is to utilize the rod that hits of rotation mutually that the granular material entering is clashed into raw material is pulverized, and has the advantages such as particle size after cracking is thin, the ratio of reduction is large, extensive use in the industries such as mine, building materials, chemical industry, feed, food, medicine, plastics.Facts have proved: China is domestic in cage mill mechanical aspects, mainly have two large problems: the one, hit that rod is the most easy to wear, service life is short.The material that routine is hit rod is mostly to make with carbon steel, plastic-steel, cast iron, stainless steel etc., and hits the long-term and material friction of rod, collision, and material is not wear-resisting, consumes larger.In general, a set of disintegrating machine monthly needs with common 300 left and right of rod of hitting, and waste is large, and production cost is high; The 2nd, during replacement cost, take a lot of work, affect the normal production order and work efficiency, if change not in time in production, hit rod and can badly influence crushing effect, be difficult to reach grinding particle size.Therefore, be necessary it to make further improvements.
Summary of the invention
The utility model just can effectively overcome above-mentioned technical disadvantages, provide have design science rationally, the compound rod device that hits of a kind of cage mill of the feature such as long service life, simple in structure, high strength, high rigidity, wearability be strong, it is widely used in crushing material and the mixture operation of the industries such as chemical industry, building materials, mine, electric power, metallurgy, grain, is to substitute the ideal product that current conventional disintegrating machine hits rod.
Technical purpose of the present utility model is achieved in that the compound rod device that hits of a kind of cage mill, round steel, band steel, complex abrasion-proof metal, is consisted of.Round steel is positioned at the both sides of this device, and band steel is positioned at the central authorities of this device, and round steel is connected with the mode of band steel by welding, and complex abrasion-proof metal evenly casts in the surface of round steel, band steel.
Described round steel, band steel are an integral body;
Described round steel, band steel are to adopt intensity mild steel high, good toughness to be welded;
A plurality of apertures of the same size on described band steel, have been equidistantly distributed;
Described complex abrasion-proof metal material is the integral body that the steel alloy casting of employing high rigidity, high abrasion forms;
Described complex abrasion-proof metal is corresponding one by one with the structure of round steel, band steel;
The described thickness that casts in round steel, the lip-deep complex abrasion-proof metal of band steel is greater than 15mm;
The technical scheme that the utility model adopts is: by adopting Technology of EPC, two kinds of unlike materials are combined with each other, produce the wear-resisting rod that hits.Be exactly first to manufacture the rod fuse base material of launching an attack specifically, i.e. round steel, band steel, its material is mild steel, has high strength and excellent toughness, while guaranteeing round steel, band steel work, can bear greater impact power; Again by Technology of EPC, hitting rod fuse base material appearance cast equably one deck high rigidity, highly wear-resisting alloy steel, make it to melt as a whole, reach the object of metallurgical binding.
The utility model---the compound operation principle of hitting rod device of a kind of cage mill: present stage the broken material such as chemical industry, building materials, mine cage mill, it hits rod and very easily weares and teares, service life is short, for improving service life, adopt high hardness material, but intensity is inadequate again, be difficult to meet its production requirement.The utility model adopts complex technique, the material of, good toughness large by intensity is as hitting rod base material, by casting technique, the material of high rigidity, high-wearing feature is cast in to substrate surface, shape all-in-one-piece complex abrasion-proof hits rod device, has improved significantly the service life of hitting rod.
The beneficial effects of the utility model are:
1, long service life is 3-5 times that single material is hit rod.What adopt because of the round steel of the utility model product, band steel is that intensity is high, the casting of the mild steel of good toughness, Technology of EPC is passed through on its surface, the steel alloy casting of high rigidity, high abrasion is formed, so increase its wear-resistant degree, while guaranteeing round steel, band steel work, can bear greater impact power, make to hit rod fuse and more can stand in the course of the work collision, the friction with material, not fragile, not yielding, durable in use.
2, simple in structure, successful.The utility model is simple in structure, and round steel, band steel are originally an integral body, be by being welded, and complex abrasion-proof metal is to cast in its surface by Technology of EPC, has just reached the object of improving material crushing effect, saving of work and time.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is made to more full and accurate explanation
Fig. 1 is structural representation of the present utility model and doubles as Figure of abstract
In figure: 1, round steel, 2, band steel, 3, complex abrasion-proof metal
The specific embodiment
The compound rod device that hits, is comprised of round steel (1), band steel (2), complex abrasion-proof metal (3).Round steel (1) is positioned at the both sides of this device, band steel (2) is positioned at the central authorities of this device, round steel (1) is connected with the mode of band steel (2) by welding, and complex abrasion-proof metal (3) evenly casts in the surface of round steel (1), band steel (2).
During work: send wanted broken material to cage mill feeding mouth, start power supply, the rod that hits being comprised of round steel (1), band steel (2) in cage mill starts opposite direction rotating, because complex abrasion-proof metal (3) is to cast in its surface, so rotation is got up together, has also realized the object to material fragmentation when bumping, impacting with material.
Above-described embodiment is only one of preferred embodiment of the present utility model; not with this, limit protection domain of the present utility model; therefore: all equivalences of doing according to shape of the present utility model, structure, principle change, within all should being covered by protection domain of the present utility model.
