Abstract
The utility model discloses a coal injection pipe which belongs to the field of smelting equipment, and structurally comprises an outer metal wire soft package tube, a rubber lining tube and an inner metal lining tube, wherein the front end of the inner metal lining tube is connected with a clamping connector; the rubber lining tube is sheathed outside the inner metal lining tube; and the outer metal wire soft package tube is sheathed outside the rubber lining tube. Compared with the prior art, the coal injection pipe has the advantages of reasonable design, simple structure, easiness for machining, convenience for installation, low noise, long service life and the like, can effectively improve the production efficiency, and ensures pea coal transferring speed and quality.
Description
Technical field
The utility model relates to the smelting equipment field, specifically a kind of coal powder injection pipe.
Background technology
The coal that iron-smelting blast furnace uses is that the diameter of beans is about 200 orders through the beans of screening, approximately 0.074mm.The pipeline that transmits at present beans in the iron manufacturing process mainly is two kinds of sebific duct or flange-connection stainless steel metal flexible pipes, uses simple sebific duct transmission beans, can guarantee the transfer rate and the quality of beans, but sebific duct is not wear-resisting, non-refractory, and work-ing life is extremely short, and is uneconomical; Use simple flange-connection stainless steel metal flexible pipe, can guarantee use temperature, but corrugated tube in the form of a ring, not only the part is wear-resisting but also easily form eddy current, greatly reduces the transfer rate of beans, influences output.
Summary of the invention
Technical assignment of the present utility model is at above weak point, provide a kind of easy for installation, noise is low, a kind of coal powder injection pipe of long service life.
The technical scheme that its technical problem that solves the utility model adopts is: this coal powder injection pipe comprises outer wire Soft Roll pipe, rubber bushing pipe and metal inner lining pipe, and the front end of metal inner lining pipe and cassette connecting joint link together; The outside of metal inner lining pipe is with the rubber bushing pipe, and the outside of rubber bushing pipe is with outer wire Soft Roll pipe.
The junction of described metal inner lining pipe and cassette connecting joint is with the liner sleeve.
The front opening place of described outer wire Soft Roll pipe and rubber bushing pipe is with outer sleeve.
A kind of coal powder injection pipe of the present utility model is compared with prior art, have reasonable in design, simple in structure, be easy to processing, easy for installation, characteristics such as noise is low, long service life, effectively raise production efficiency, guaranteed the transfer rate and the quality of beans.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing is a kind of structural representation of coal powder injection pipe.
Among the figure: 1, cassette connecting joint, 2, the liner sleeve, 3, outer sleeve, 4, outer wire Soft Roll pipe, 5, the rubber bushing pipe, 6, the metal inner lining pipe.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
A kind of coal powder injection pipe of the present utility model, its structure comprises outer wire Soft Roll pipe 4, rubber bushing pipe 5 and metal inner lining pipe 6, the front end of metal inner lining pipe 6 and cassette connecting joint 1 link together, and metal inner lining pipe 6 is with liner sleeve 2 with the junction of cassette connecting joint 1; The outside of metal inner lining pipe 6 is with rubber bushing pipe 5, and the outside of rubber bushing pipe 5 is with outer wire Soft Roll pipe 4, and the front opening place of outer wire Soft Roll pipe 4 and rubber bushing pipe 5 is with outer sleeve 3.
A kind of its processing and fabricating of coal powder injection pipe of the present utility model is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characterictic of specification sheets, be the known technology of those skilled in the art.
