Description
Technical field
The utility model belongs to mining equiment technical field, belongs to grinding attachment technical field further, is specifically related to a kind of structure simply, easy for installation, uses reliable, effectively can avoid the autogenous tumbling mill feed end structure of hollow shaft liner wear.
Background technology
Autogenous tumbling mill is the visual plant in ore-dressing technique, and mainly carry at the beginning of being carried out by bulk tcrude ore broken, is the tap device in ore-dressing technique, once autogenous tumbling mill is stopped transport, all mineral processing circuits afterwards all will stop, and cause tremendous influence to production, bring huge economic loss by enterprise.The autogenous tumbling mill of prior art, in order to avoid damage hollow shaft, in hollow shaft endoporus, be provided with hollow shaft lining, but due to feed end with to trolley bell mouth and part ore to contact to produce to wear and tear, cause feed end hollow shaft lining in use by ore and ore pulp serious wear.In the ordinary course of things, feed end hollow shaft liner wear speed, after hole is led in hollow shaft liner wear, ore and ore pulp can enter into hollow shaft, cause the damage of hollow shaft, and hollow shaft is once damage is scrapped, must change, larger economic loss will be caused, and affect production operation.Will change after general hollow shaft lining uses a period of time, and hollow shaft lining is changed frequent, and replacing construction be long, labor strength is large, invisible like this waste just causing spare part resource, adds the production cost of enterprise, have impact on the economic benefit of enterprise.For this reason, research and develop a kind of structure simple, easy for installation, use reliable, the autogenous tumbling mill feed end structure effectively can avoiding hollow shaft liner wear is the key addressed this problem.
Utility model content
It is simple, easy for installation that the purpose of this utility model is to provide a kind of structure, uses reliable, effectively can avoid the autogenous tumbling mill feed end structure of hollow shaft liner wear.
The purpose of this utility model is achieved in that and comprises hollow shaft lining, studs, hollow shaft, autogenous tumbling mill end cap, end cap liner plate, arranges hollow shaft lining in the endoporus of described hollow shaft; The front end face of described hollow shaft is affixed by the flange of studs and hollow shaft lining; The rear end face of described hollow shaft is affixed by the front end face of studs and autogenous tumbling mill end cap; The inner side of described autogenous tumbling mill end cap arranges end cap liner plate; In the endoporus of described hollow shaft lining, protection lining is set; Described protection lining and hollow shaft lining affixed.
The utility model arranges protection lining in the endoporus of hollow shaft lining, avoids ore and ore pulp directly touches hollow shaft lining, thus avoids the wearing and tearing of hollow shaft lining; After protection lining uses a period of time, when can not continue to use owing to wearing and tearing, directly can change protection lining in the hollow shaft lining of autogenous tumbling mill feed end, and hollow shaft lining need not be changed; Protection lining is split-type structural, is made up of more than one piece, changes very convenient, fast like this.
The utility model extends the service life of hollow shaft lining, and protects the replacing construction of lining short, and labor strength is little, and reduce the difficulty of examine and replace, the repair time is short; Add the production operation time simultaneously, decrease spare part use amount, reduce production cost, improve the economic benefit of enterprise.The utility model structure is simple, easy for installation, uses reliable, effectively can avoid the wearing and tearing of hollow shaft lining.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the utility model;
Fig. 2 is the main cross-sectional schematic of protection lining of the utility model;
In figure: 1-hollow shaft lining, 2-studs, 3-hollow shaft, 4-autogenous tumbling mill end cap, 5-end cap liner plate, 6-protects lining, and 7-stud is secondary, 8-cylindrical shell, 9-shell liner.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, but limited the utility model never in any form, based on any conversion that the utility model training centre is done, all falls into the utility model protection domain.
As shown in Fig. 1 ~ 2, the utility model comprises hollow shaft lining 1, studs 2, hollow shaft 3, autogenous tumbling mill end cap 4, end cap liner plate 5, arranges hollow shaft lining 1 in the endoporus of described hollow shaft 3; The front end face of described hollow shaft 3 is affixed with the flange of hollow shaft lining 1 by studs 2; The rear end face of described hollow shaft 3 is affixed with the front end face of autogenous tumbling mill end cap 4 by studs 2; The inner side of described autogenous tumbling mill end cap 4 arranges end cap liner plate 5; Protection lining 6 is set in the endoporus of described hollow shaft lining 1; Described protection lining 6 is affixed with hollow shaft lining 1.
Described protection lining 6 is in circular cone shell-like, and its outer cone tapering is consistent with the hole taper of hollow shaft lining 1.
Described protection lining 6 is fabricated structure.
The size of the size of described protection lining 6 and the endoporus of hollow shaft lining 1 adapts.
The thickness of described protection lining 6 is 20 ~ 30mm.
Length 10 ~ the 20mm less of the length of hollow shaft lining 1 of described protection lining 6.
Described protection lining 6 is made by the metal material or nonmetallic materials with good abrasion resistance.
When described protection lining 6 is metal material, with hollow shaft lining 1 firm welding.
operation principle of the present utility model and the course of work:
The utility model arranges protection lining 6 in the endoporus of hollow shaft lining 1, avoids ore and ore pulp directly touches hollow shaft lining 1, thus avoids the wearing and tearing of hollow shaft lining 1; After protection lining 6 uses a period of time, when can not continue to use owing to wearing and tearing, directly can change protection lining 6 in the hollow shaft lining 1 of autogenous tumbling mill feed end, and hollow shaft lining 1 need not be changed; Protection lining 6 is split-type structural, is made up of more than one piece, changes very convenient, fast like this.
