Abstract
The utility model discloses a novel chain for a coal washer, which comprises a plurality of basic units. One of the basic units includes an inner chain plate, an outer chain plate, a pin shaft and a sleeve. The novel chain is characterized in that a chromizing layer is arranged on the surface of the sleeve. After the surface of the sleeve is processed with alloy coating, the abrasion resistance and the corrosion resistance of the chain are improved, and the service life of the chain is prolonged.
Description
Technical field:
The utility model relates generally to a kind of chain, relates in particular to a kind of sleeve to be carried out the chain that alloy is laminated with processing.
Background technology:
Use a kind of chain on the shallow slot equipment of coal fine purifiation manufacturing line, the structure of this chain is the sleeve conveyer chain, does not have roller, between sleeve and guide rail cliding friction takes place during the chain operation.Because have mixed liquors such as a large amount of coal slimes, iron medium, sulfide in the shallow slot equipment of fine purifiation coal, the chain of conventional design manufacturing will lose efficacy because of severe wear less than three months service life.Therefore, the domestic fine purifiation coal industry import chain that places one's entire reliance upon, price is higher.At present, domestic chain is selected the sleeve through the alloy steel cementation process for use according to engineering chain technical standard, its superficial hardness is 58～63HRC, but chain barrel is very fast by severe wear, and serious tubercular corrosion does not appear in the abrading section yet, out of reach client far away desired service life.
Technology contents:
The purpose of this utility model is exactly in order to remedy the defective of prior art, the novel coal washer chain that provides a kind of wear resisting property and corrosion resistance obviously to improve.
The utility model is achieved through the following technical solutions:
Novel coal washer chain is made up of several elementary cells, and an elementary cell includes inner plate, pin link plate, bearing pin and sleeve, it is characterized in that: described sleeve surface has the chromising layer.
For improving the wear resisting property of chain, the present invention has carried out deep analysis and judgement, and find that quick wearing and tearing mainly are to have serious abrasive material and corrosion wear in the chain operational process, and interact, the wearing and tearing of aggravation sleeve, thus cause chain to lose efficacy.Therefore simple dependence improves piece surface hardness or improves the service life that decay resistance all can not fundamentally prolong chain.
In view of this, the present invention proposes increases chromising surface-treated scheme to sleeve on the basis of the former selection of employing with former Technology for Heating Processing, sleeve surface is carried out after alloy is laminated with processing, its superficial hardness can reach micro-vickers hardness more than 1100, and the alloy on surface is laminated with the corrosion resistance that layer can effectively improve piece surface, fundamentally reach the resistance to abrasion that improves chain, the effect that prolongs its service life.
Improve rear chain and use checking through the client, the life-span has reached more than seven months, and its wear resisting property is all led over the similar chain product of import with corrosion resistance.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
The coal washer chain is made up of several elementary cells, and an elementary cell includes inner plate 1, pin link plate 2, bearing pin 3 and sleeve 4, and sleeve surface is laminated with processing through alloy, is covered with chromising layer 5.
