Abstract
The utility model discloses an automatic protective gas supplying device of an annular cover type annealing furnace. The protective gas automatic air supplying device comprises an annular furnace bottom, a rotating shaft, an air inlet pipeline and an air supplying joint, wherein the rotating shaft is positioned on the center position of the annular furnace bottom, and the annular furnace bottom rotates along with the rotating shaft; the special point is that the air inlet pipeline and the air supplying joint are arranged in the rotating shaft, the air supplying joint is composed of an air supplying pipeline and a liquid storing groove arranged on the periphery of the upper part of the air supplying pipeline, and the air inlet pipeline is buckled in the liquid storing groove arranged above the air supplying joint. The device is adopted to carry out automatic air supply on the gas in an industrial furnace, a condition that the labor intensity of workers is reduced is realized, the production cost is reduced, and the sealing property of the air supplying device is good.
Description
Technical field
The utility model belongs to annular bell-type annealing furnace structure technical field, specifically refers to a kind of annular bell-type annealing furnace protective gas body automatic inflating-air device.
Background technology
The general characteristic of annular bell type annealing furnace is install combustion device on the tunnel like annular body of heater of fixing, the naked light burning; Place inner cover on pallet car type ring-shaped furnace bottom 1 with turning axle 2 rotations, be full of shielding gas and the stacking coil of strips such as hydrogen, nitrogen in cover, continuous annealing.The air feeder structure of existing past inner cover input gas as shown in Figure 1, comprise and be arranged in intake ducting 3 and a plurality of air connector 4 with the joint that commutates fast that arranges by inner cover quantity on pallet car type ring-shaped furnace bottom 1, one end of every intake ducting 3 is through the corresponding inner cover of furnace bottom access, the interior Non-return air valve that arranges of intake ducting 3; One end of air connector 4 can insert intake ducting 3 and be connected by flexible pipe 8 with air-supplying valve 7 on being arranged in annular furnace binding to inner cover air feed, the other end.Existing air feed operating method is: when ring-shaped furnace bottom 1 turns clockwise, intake ducting 3 rotates thereupon, and air connector 4 does not rotate.Ring-shaped furnace bottom 1 when inadequate, need to unload next air connector 4 manually rotating to connecting hose 8 length, rapidly another air connector 4 is inserted another intake ductings 3, thus realize with ring-shaped furnace bottom 1 rotation commutate, the change place air feed.Adopt this gas mode, not only need operator at the numerous replacing joint of stove side frequency, workload is large, working efficiency is not high, and has easy gas leakage problem, causes covering composition and the pressure transient of interior gas, thereby the difficult quality of annealing product is controlled.
Summary of the invention
The purpose of this utility model will provide a kind of annular bell-type annealing furnace protective gas body automatic inflating-air device exactly; adopt this device can realize the gas in industrial furnace is carried out automatic feeding; thereby can realize reducing workman's working strength; reduce production costs, and this automatic inflating-air device favorable sealing property.
For achieving the above object; annular bell-type annealing furnace protective gas body automatic inflating-air device of the present utility model; comprise ring-shaped furnace bottom; turning axle, intake ducting and air connector; described turning axle is positioned at the ring-shaped furnace bottom central position; ring-shaped furnace bottom rotates with turning axle; its special character is: described intake ducting and air connector are arranged on interior of rotating shaft; described air connector is made of steam line and the reservoir that is arranged at the steam line top periphery, and described intake ducting snaps onto in the reservoir of described air connector top.
Preferably, described intake ducting is for falling doline, and air feed speed is faster like this, and efficient is higher.
The utility model is arranged in the turning axle of ring furnace by the air feed equipment with annular bell-type annealing furnace protective gas; avoided in existing air feed equipment because of intake ducting in the problem that pivots and cause the steam line flexible pipe easily to be wound around; also need not by the artificial manual air feed in good time limit on the side; reduce labor workload, effectively improved production effect.when using automatic inflating-air device air feed of the present utility model, air connector is arranged on furnace binding and does not rotate, and is fixed tube, intake ducting and ring-shaped furnace bottom synchronous rotary are swivel pipe, only need to the certain water gaging isodensity of filling in reservoir is large, the liquid that boiling point is higher, intake ducting inserts a certain degree of depth in reservoir liquid level below, and and steam line consist of that between a pipe, the gap is got final product by the Vertical Channel of hydraulic seal, shielding gas flows into air connector through air-supplying valve, flow into again intake ducting, then enter the protection inner cover of making circumferential motion, like this movable fluid-tight is carried out in the gap between intake ducting and air connector, realized the encapsulation process to airing system, thereby can effectively overcome because of the rotation of inlet pipe and radially, up and down play and the problem of leaking gas.
