Abstract

The utility model relates to a composite ceramic variable-diameter pipe used in an ash conveying pipeline, a mine slag conveying pipeline and the like in a thermal power plant. A ceramic abrasion-resistant layer is lined at the abrasion position of the inner surface of a metal skeleton pipe; and a metal skeleton is tightly combined with the ceramic abrasion-resistant layer into a whole body; and the composite ceramic variable-diameter pipe has good abrasion resistance, temperature resistance, abrasion resistance and erosion resistance, so that the abrasion intensity of particles, slurry or mediums with serious erosion and strong corrosion property to the ceramic variable-diameter pipe during the use is greatly reduced, and the service life of the composite ceramic variable-diameter pipe is prolonged.

Description

The composite ceramics reducer pipe
Affiliated technical field:
The composite ceramics reducer pipe that the utility model relates to uses such as thermal power plant lime-ash delivery line, mill tailings delivery line (has another name called: the composite ceramics CONCENTRIC REDUCER), especially thermal power plant, Iron And Steel Plant etc. use many, reduced abrasion in the using process, ensured good sealing effect it.
Background technique:
At present, when known reducer pipe uses, easy to wear; in very short time, just wear away, and non-refractory, not corrosion-resistant, easily wash away, working life is short; it is to paste or paster that abrasion cause poor sealing performance, some ceramic reducer pipe, pottery soon; easily come off; cause working life short, the shutdown of equipment is changed, and influence is produced; expensive manual maintenance expense greatly reduces manufacturing efficiency.
Summary of the invention:
For the defective that abrasion are fast, working life is short that overcomes existing reducer pipe or ceramic reducer pipe, this use is novel to provide a kind of composite ceramics reducer pipe, at metallic interior surface liner composite ceramics wearing layer, the outside is a metal frame, reducer pipe lined ceramics wearing layer, ceramic wearing coat is the bulk ceramics pipe through isostatic compaction, ceramic wearing coat and metal frame utilize the characteristic of high temperature that both are closely as one, this composite ceramics reducer pipe is wear-resistant, high temperature resistant, anti-to be washed away, corrosion-resistant, prolong its working life greatly, improved efficiency of equipment.
The technological scheme that its technical problem that solves the utility model adopts is: on the basis of virgin metal reducer pipe, metal frame internal surface lined ceramics wearing layer, metal frame and ceramic wearing coat are closely as one through the high temperature assembling, can reach good wear-resisting effect and sealing effect, adopting wear-resistant material is industrial ceramics, can improve wear-resisting, abrasion resistance, resistance to high temperature greatly, reach the purpose of long service life reducer pipe.
The beneficial effects of the utility model are: metal frame and composite ceramics wearing layer are assembled into one, good wear-resisting, heatproof are arranged, abrasion resistance, good corrosion resistance, reduce wear and improve working life, the composite ceramics wearing layer is the bulk ceramics pipe through isostatic compaction, avoided the problem of easily taking off of chip ceramic, and good self lubricity is arranged, be difficult for scabbing.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is a longitudinal section of the present utility model erection drawing
Fig. 2 is the sectional view of metal frame
Fig. 3 is the sectional view of ceramic wearing coat
Embodiment:
1. metal frames among the figure, 2 ceramic wearing coats.
In Fig. 1, metal frame (1) is assembled into one with ceramic wearing coat (2) through high temperature, the sectional view after both assemblings.
In embodiment illustrated in fig. 2, the sectional view of metal frame (1).

Claims (3)

1. composite ceramics reducer pipe, the outside is a metal frame, reducer pipe lined ceramics wearing layer, its feature: in the composite ceramics reducer pipe, ceramic wearing coat and metal frame utilize the characteristic of high temperature that both are closely as one.
2. composite ceramics reducer pipe according to claim 1 is characterized in that: ceramic wearing coat is the bulk ceramics pipe through isostatic compaction.
3. composite ceramics reducer pipe according to claim 1 is characterized in that: the wearing layer material adopts industrial ceramics.
