Abstract
The invention relates to a conveying pipe, in particular to an inverted tooth gravel conveying pipe. The conveying pipe comprises a pipeline steel substrate, a metal alloy transition layer and superhard material particles, wherein the metal alloy transition layer and the superhard material particles are arranged on an internal wall of the pipeline steel substrate; metal inverted teeth are fixed on the pipeline steel substrate; tooth tips of the metal inverted teeth face an outlet of the conveying pipe; the metal inverted teeth are high manganese steel inverted teeth; the conveying pipe can prevent sundries flowing in the pipe from backflow, so that the working efficiency of dredging is higher.
Description
Technical field
The present invention relates to a kind of delivery pipe, especially pawl molding sand stone delivery pipe.
Background technique
Existing training of river channel all needs to use delivery pipe that the foreign material such as mud, sandstone are carried out strand suction and goes out, and metal alloy coating in pipeline is as the wear-resisting main process means of delivery pipe, but the foreign material in pipeline may produce backflow because of external pressure, thus reduce the working efficiency of its blowdown.
Summary of the invention
Having the deficiency of backflow in order to overcome existing delivery pipe foreign material, the invention provides pawl molding sand stone delivery pipe.
The technical solution adopted for the present invention to solve the technical problems is: pawl molding sand stone delivery pipe, comprise pipe line steel matrix, metal alloy transition layer and superhard material particle, pipe line steel matrix inwall is provided with metal alloy transition layer and superhard material particle, pipe line steel matrix is fixed with metal pawl.
According to another embodiment of the invention, the direction that the crown comprising metal pawl further exports towards delivery pipe.
According to another embodiment of the invention, comprising metal pawl is further high manganese steel pawl.
The invention has the beneficial effects as follows, this delivery pipe can make can not flow backwards at the foreign material of Bottomhole pressure, thus makes dredging working efficiency higher.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention;
1. pipe line steel matrixes, 2. metal alloy transition layer, 3. superhard material particle, 4. metal pawl in figure.
Embodiment
If Fig. 1 is structural representation of the present invention, pawl molding sand stone delivery pipe, comprise pipe line steel matrix 1, metal alloy transition layer 2 and superhard material particle 3, pipe line steel matrix 1 inwall is provided with metal alloy transition layer 2 and superhard material particle 3, pipe line steel matrix 1 is fixed with metal pawl 4, the direction that the crown of metal pawl 4 exports towards delivery pipe, metal pawl 4 is high manganese steel pawl.
Metal pawl 4 is covered with in pipe line steel matrix 1, metal pawl 4 uses high manganese steel material, its abrasion resistance can be ensured like this, and the crown of metal pawl 4 is towards stopping foreign material from flowing in the other direction, this delivery pipe can make can not flow backwards at the foreign material of Bottomhole pressure, thus makes dredging working efficiency higher.
