Abstract
The utility model relates to a pipe with a composite wear-resistant liner at the inner wall, belonging to the field of pipe manufacture. The section structure of the pipe is provided with a pipe wall, a first adhesive layer, a buffer layer, a second adhesive layer, and a rubber plastic mixed material layer. The first adhesive layer is divided into a rubber receiving layer, a butadiene-styrene rubber layer, a butadiene-styrene rubber layer, and a natural rubber layer. The buffer layer is a foam rubber layer or a rubber plastic body with high elasticity. The utility model has the characteristics of wear resistance, aging resistance, high-speed shock resistance, acid resistance, alkali resistance, salt resistance, ozone resistance, etc. The utility model has the advantages of multiple conveying mediums, lightness, and low cost, and can be used for conveying coal powders of power plants, the ores of mines, corrosive mediums of chemical industry systems, water flow with mud and sand, etc.
Description
The utility model relates to carries gas-solid, pipeline, particularly inner-walls of duct liquid-solid, the solid, powdery medium to be lined with the pipeline of high-abrasive material.Metal conduit is made the field.
In industrial production, to use line transportation powdery solid material,, contain the conveying etc. of the current of silt as the coal dust of power station, the conveying of coal ash.Because solid matter makes pipe wear serious to the friction of tube wall, working life is very short, needs often to change pipeline.Have employing to set up pad underlayer at inner-walls of duct at present, as rubber, plastics etc., but its working life is also shorter.
The purpose of this utility model provides the pipeline that a kind of inwall has the complex abrasion-proof layer.
The utility model inwall is formed (see figure 1) by the pipeline cross-section structure of complex abrasion-proof layer by five layers.Be respectively tube wall, first adhesive layer, buffer layer, second adhesive layer, rubber and plastic mixed material layer.
Buffer layer plays the effect of buffering transmission medium impact force, can bear the impact of the high-velocity fluid of 20～30 meter per seconds, can improve the speed that transmits fluid.The rubber and plastic blending material has very high wear resistance and corrosion resistance, and is anti-aging, and the mechanical deterioration ability of opposing transmission medium is strong, so can improve the working life of pipeline greatly.
Illustrate that accompanying drawing is as follows:
Fig. 1 has the sectional drawing of complex abrasion-proof layer pipeline for the utility model inwall.
Fig. 2 is the sectional drawing of first adhesive layer.
Accompanying drawings embodiment is as follows:
1 is tube wall among Fig. 1, and 2 is first adhesive layer, and 3 is buffer layer, and 4 is second adhesive layer, and 5 is the rubber and plastic mixed material layer.First adhesive layer (2) is formed (see figure 2) by four layers and is respectively Lie Kena adhesives layer (6), neoprene glue-line (7), butylbenzene glue-line (8), caoutchouc layer (9).Buffer layer (3) is elastomeric layer such as sponge rubber or high elasticity rubber and plastic body.Second adhesive layer is a synthetic rubber.
Because adopt said structure, the utility model inwall has the pipeline of complex abrasion-proof layer to have high abrasion, and is ageing-resistant, anti-high speed impact, characteristics such as acid-and base-resisting, salt, ozone, the medium kind that can carry is many, and is in light weight, and cost is low.Can be used for the conveying of power plant's coal dust, the conveying of mine ore in sand form, the conveying of chemical system Korrosionsmedium contains the conveying of mud, sand current etc.
Claims (2)
1, a kind of inwall has the pipeline of complex abrasion-proof layer, it is characterized in that the pipeline cross-section structure has five layers, is respectively tube wall, first adhesive layer, buffer layer, second adhesive layer, rubber and plastic mixed material layer.
The pipeline that 2, the complex abrasion-proof layer is arranged according to the said inwall of claim 1 is characterized in that said first adhesive layer is divided into four layers, is respectively Lie Kena glue-line, neoprene glue-line, butylbenzene glue-line, caoutchouc layer.
