Description
Technical field
The present invention relates to assembling pipe joint, specifically a kind of be applicable to Rotary Anode Furnace can rotating pipe connector lug, particularly relate to a kind of rotary type pipe joint.
Background technique
During copper was smelted, Rotary Anode Furnace was few because of its radiation loss, sealing strong, good operational environment, mechanization degree are high, flexible operation and labor intensity are little, had obtained using very widely.Rotary Anode Furnace needs around the cylindrical shell center steering in process of production; Its burner is located at an end of cylindrical shell; When body of heater turns round, be the also rotation simultaneously of pipeline of the burner fuel supplying or the wind that burns, the medium transport pipeline joins through a swivel coupling and rotating pipeline.Traditional swivel coupling is the revolution of single pipe.
Use fine coal to do the Rotary Anode Furnace of fuel, its burner need supply fine coal and burning wind simultaneously, and coal convey pipe and ajutage need separately be supplied.According to the conventional method design, when body of heater rotated, a delivery pipe was followed the body of heater rotation, and another root delivery pipe can only connect through flexible pipe.But the fine coal pipe is that gas-solid mixes conveying, and burning airduct caliber is bigger, all is not suitable for using flexible pipe to carry.This just makes Rotary Anode Furnace select the fine coal comparison difficulty that acts as a fuel.
Summary of the invention
The object of the present invention is to provide a kind of joint, the bigger pipeline of caliber is turned round with one heart.
The objective of the invention is to realize that through following technological scheme the rotary type pipe joint is made up of big rotary disk group and little rotary disk group; Big rotary disk group comprises big outer collar, land, dish joint, and little rotary disk group comprises little outer collar, joint, and the center is set with said little rotary disk group in the said big rotary disk group; Big outer collar one peripheral inboard is provided with step; The opposite side periphery is provided with fastening piece, and land is a plate-like, and card center and periphery are equipped with through hole; The through hole at card center is fixed with the joint of little rotary disk group, and the through hole of periphery is fixed with the dish joint; Two land rims are installed in the big outer collar in opposite directions, and loose collar is equipped with in the inboard, rim, and the rim jointing is equipped with Sealing, and the dish joint is connected with delivery pipe A through flange plate; Little outer collar periphery one inboard of little rotary disk group is provided with fastening piece, and joint one end is a tubulose, and two joints are loaded in the little outer collar in opposite directions; Joint is equipped with loose collar in the inboard, joint in opposite directions; Between the joint butt joint Sealing is housed, the joint the other end is equipped with flange plate, and is connected with delivery pipe B.
Said loose collar is the circle shape, and its periphery is stuck in rim or the joint inboard of joint in opposite directions respectively.
Said Sealing is seal ring or sealing strip.
Said fastening piece is screw or bolt or pin.
Advantage of the present invention is, is made up of large and small two rotary disk groups, and structural type is identical, forms and all can turn round each other by 3 layers of cannula-like part, uses flexibly, and maintenance is convenient.
