Abstract
The utility model discloses a double-layer compound protective cover of a grate plate with a signal roller, which comprises a protective cover body; hoisting holes which are symmetrically arranged are arranged on the protective cover body; the protective cover body is a common steel layer; a working surface of the protective cover body is provided with a heat-resisting and wear-resisting alloy steel layer; and the double-layer compound protective cover has the advantages of being low in cost, high in efficiency, and not easy to break during water injection for overhaul.
Description
Technical field
The utility model relates to a kind of single roll crusher comb plate protective cap, relates in particular to a kind of single roller comb plate two-layer compound protective cap.
Background technology
The sinter cake that sintering machine is turned down need be crushed to below the 150mm, could get into the screening and the cooling device of heat sinter.Single roll crusher is exactly that the bulk heat sinter is carried out fragmentation, the highest thick broken equipment that can reach about 900 ℃ of operating temperature continuously.The comb plate is that multi-disc or monolithic are arranged and be shelved in the body stopper slot, and disintegrating machine discaling roll and comb plate cooperate shearingly the sintering deposit on the conveyer belt is carried out continuous crushing.Usually; Single roll crusher comb panel assembly is made up of comb plate body and protective cap; Be that protective cap is sleeved on the comb plate body, comb plate body and protective cap are the symmetrical structure form, owing to be in the hot operation district and will bear the mechanical impact force of breaker roll near the comb plate body of breaker roll one end; In order to prolong the service life of protective cap; Protective cap adopts the heat-resistance abrasion-resistance alloy steel to do usually, all has only the service life of single head about 2 months, re-uses the protective cap of another side after one when after the protective cap wearing and tearing on one side it being turned round.As not having the protection of protective cap, high-temperature material will directly impact the comb plate body, and the comb plate body is an ordinary steel, very easily rubs, and can cause the production equipment accident like this.In the actual production, after protective cap work a period of time, in maintenance or when turning round protective cap, need the water filling cooling, when the protective cap of doing with whole heat-resistance abrasion-resistance alloy steel received water-cooled but, fracture easily caused protective cap to damage, and can not use the increase production cost; Simultaneously, the protective cap cost of doing with whole heat-resistance abrasion-resistance alloy steel is also than higher.
Summary of the invention
It is not enough be to solve prior art, and the utility model provides a kind of cost low, and efficient is high, single roller comb plate two-layer compound protective cap of easy fracture not during the maintenance water filling.
The utility model adopts following technical scheme: single roller comb plate two-layer compound protective cap; Comprise the protective cap body; Described protective cap body is provided with symmetrically arranged hole for hoist; It is characterized in that: described protective cap body is the ordinary steel layer, and the working face of described protective cap body is provided with one deck heat-resistance abrasion-resistance alloy steel layer.
The bottom of described protective cap body is provided with mounting groove.
The bottom of described protective cap body is provided with lug boss.
The thickness of described protective cap body ordinary steel layer is 205mm, and the thickness of described heat-resistance abrasion-resistance alloy steel layer is 30-50mm, and the diameter of described hole for hoist is 60 mm.
When producing the utility model, earlier with the ordinary steel protective cap body of having cast, again at working face top casting one deck heat-resistance abrasion-resistance alloy steel layer of the good protective cap body of casting.
The protective cap that the utility model list roller comb plate two-layer compound protective cap is made whole heat-resistance abrasion-resistance alloy steel of the prior art changes on the working face of the protective cap body that ordinary steel is made and is provided with one deck heat-resistance abrasion-resistance alloy steel layer, and the one, cost reduces; The 2nd, when overhauling or turning round protective cap water filling cooling, the utility model list roller comb plate two-layer compound protective cap is easy fracture not.
The beneficial effect of the utility model list roller comb plate two-layer compound protective cap is: cost is low, and efficient is high, easy fracture not during the maintenance water filling.
