Description
Technical field
The utility model relates to a kind of multiple tube of being made up of rare earth microcrystalline coating, frp layer and metal connecting piece.
Background technique
The conveyance conduit that is used for concrete mixer at present adopts metallic conduit more, and for improving the wear resistance and the bearing strength of metallic conduit, common metallic conduit is made up of wear-resisting alloy steel internal layer and carbon steel skin.But the perishable wearing and tearing of metallic conduit, the highest have only about 20,000 sides working life when delivering concrete, and therefore less than 10,000 sides need often to change pipeline usually, and the conveying cost is improved greatly.In order to reduce the replacing number of times, the tube wall excessive wear usually takes place, cause the quick-fried phenomenon of pipe, bring potential safety hazard for the workmen of periphery.Therefore the insecurity of metallic conduit and not anti abrasive economy problems become the power of research and development high performance-price ratio multiple tube.
The model utility content
Based on analysis to present mortar, concrete, liquid-solid two-phase fluid composite tube for conveying road, to understand after its deficiency, the purpose of the utility model is to provide a kind of intensity high, wear-resisting, corrosion-resistant, and NEW TYPE OF COMPOSITE pipeline easy to connect is installed.This pipeline is different according to its size, also can be used as other solid powder, the conveyance conduit of liquid-solid two-phase fluid.
For realizing above-mentioned purpose, the utility model is taked following technological scheme:
A kind of multiple tube of forming by rare earth microcrystalline coating, frp layer and metal connecting piece; The liner of this multiple tube is the glass-ceramic layer that contains rare earth; Be surrounded by frp layer containing outside the glass-ceramic layer of rare earth, the two ends of this multiple tube connect metal connecting piece.Described frp layer is to adopt glass fibre to twine also the method for the lamination of sprayed resin at the take-up strap position again; Form frp layer; Frp layer is fixed in contains on the glass-ceramic layer of rare earth; Like this, the glass-ceramic layer bearing capacity that this multiple tube particularly contains rare earth is strengthened.
In the multiple tube of being made up of rare earth microcrystalline coating, frp layer and metal connecting piece of the utility model, described multiple tube can be a straight tube, also can be bend pipe.
In the multiple tube of being made up of rare earth microcrystalline coating, frp layer and metal connecting piece of the utility model, described metal connecting piece is metal flange or metal valley formula clip.
In the multiple tube of forming by rare earth microcrystalline coating, frp layer and metal connecting piece of the utility model; Described metal connecting piece is to be connected on the multiple tube two ends through the sleeve on it; Its concrete linkage structure is: described sleeve is enclosed within respectively on the outer wall of the glass-ceramic layer that contains rare earth at two ends of multiple tube; Adopt canoe form glass fibre reinforced plastics and and frp layer fuse, make metal connecting piece, contain the glass-ceramic layer and the frp layer Joint of rare earth.Adopt canoe, twine the lamination of glass fibre and sprayed resin on the sleeve of metal connecting piece or in the V-type groove of sleeve outer wall or the curve bath after, frp layer and metal connecting piece do not come off when stressed along the multiple tube longitudinal direction; Adopt canoe, twine and the method for the lamination of sprayed resin not only makes the multiple tube bearing capacity strengthened with glass fibre, and the glass-ceramic layer and the metal connecting piece that contain rare earth are tightened together, be convenient to the connection of multiple tube.
The utility model has the advantages that:
The multiple tube of the utility model is divided into two kinds of straight tube and bend pipes, and its wear-corrosion resistance depends on the glass-ceramic layer that contains rare earth of internal layer.The multiple tube of the utility model is a kind of sytull new material that contains rare earth, has the intensity height, and is wear-resisting, the premium properties of acid-alkali-corrosive-resisting, and its wear resistance is 50 times of abrasion resistance alloy, resistance to flexure is 3 times of pottery, nearly 200MPa.The connection of the multiple tube of the utility model adopts metal flange to connect or the clip connected of metal valley formula; The outer wall of the sleeve of metal connecting piece (generally being steel bushing) is designed with V-type groove or curve bath, has improved the join strength of the frp layer that lamination that metal connecting piece and glass fibre twine sprayed resin forms.Fill up Bond in metal connecting piece and the gap of containing the glass-ceramic layer of rare earth.With metal flange or metal valley formula link and the fixing assembling in the end of the glass-ceramic layer that contains rare earth, twine with glass fibre then and the lamination of sprayed resin, make the glass-ceramic layer that contains rare earth and metal connecting piece obtain fastening and enhancing.And multiple tube butt joint and easy for installation, this multiple tube can effectively solve mortar, the perishable wearing and tearing of concrete conveying pipe, and transported substance is in tube wall deposition, fouling, problems such as pipeline blockage.Contain glass-ceramic layer and metal flange or the metal valley formula link of rare earth fixing after; Outer lamination by glass fibre winding and sprayed resin; The sleeve portion of metal connecting piece is designed with groove; Behind the lamination of glass fibre winding and sprayed resin, formed glass fibre reinforced plastics is fixed together difficult drop-off with the glass-ceramic layer that contains rare earth.The glass-ceramic layer that contains rare earth is behind the lamination of winding of glass dimension and sprayed resin, and compressive strength significantly improves, and has guaranteed the Security of multiple tube.
Press more than the 15MPa in this multiple tube can bear, owing to adopt the glass-ceramic layer and the frp layer that contain rare earth compound, it is in light weight that the concrete pumping pipeline is had, and superpower wear-resistant decreases, and is corrosion-resistant, non-scaling, transfer efficiency advantages of higher.And pipeline butt joint and easy for installation, it can effectively solve mortar, the perishable wearing and tearing of concrete conveying pipe, and transported substance is in tube wall deposition, fouling, problems such as pipeline blockage.Also can be used as the conveyance conduit of solid powder, solid-liquid two phase fluid.
