Description
Technical field
The present invention relates to annular furnace, refer more particularly to the charging/discharging device of annular furnace.
Background technology
As everyone knows, be widely used in the rotary heating furnace of industries such as metallurgy at present, its charging/discharging device all adopts manipulator to finish material loading and discharging.Although the energy consumption of rotary heating furnace is lower, the thermal efficiency is higher, but owing to adopt manipulator work, the speed per minute of charging and discharging is below three times, can only satisfy large-diameter steel pipe in the production, in small-sized seamless steel tube production, especially in the small size bearing steel pipe's production, because the limitation of production technology, the speed of charging and discharging must guarantee per minute more than six times, so just makes that energy-efficient annular furnace can not get using in small-sized seamless steel tube production.
Summary of the invention
A technical problem to be solved by this invention is: a kind of charging/discharging device that improves the annular furnace of charging and discharging speed is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is: the charging/discharging device of annular furnace, comprise: furnace bottom and the drive unit that is opened in charging aperture and the discharging opening on the furnace wall, the outside and drives furnace bottom rotation location, the surface of described furnace bottom is provided with the distributing trough of some roads radial arrangement, the intersection of the radial alignment at inboard furnace wall and discharging opening place offers the pusher mouth, be provided with the discharging pusher in the inboard of inboard furnace wall, the push rod of discharging pusher is radial arrangement and activity is located in pusher mouth and the discharging opening; The arranged outside charging pusher of wing furnace wall outside, the push rod of charging pusher is radial arrangement and activity is located in the charging aperture.
The two ends of described distributing trough are respectively arranged with chamfering; Described charging aperture, pusher mouth and discharging opening are along punishment in advance direction conical bore from large to small.
Described several distributing troughs are evenly arranged in furnace bottom.
Be equipped with water inlet pipe and return pipe on the described inboard furnace wall, water inlet pipe is interconnected with the end of return pipe in stove and is provided with the limited block that matches with charging aperture.
The invention has the beneficial effects as follows: discharging pusher and charging pusher are set by inside and outside both sides at annular furnace, and allow the push rod of discharging pusher and charging pusher match with the distributing trough that the furnace bottom surface is radial arrangement, improve the speed of charging and discharging greatly, made energy-efficient annular furnace in small-sized seamless steel tube production, be used well.In addition, when the limited block that is arranged on water inlet pipe and return pipe end can prevent charging effectively, the invar base touch inboard furnace wall and internally the wing furnace wall cause damage.

The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present invention in detail.
As Fig. 1, shown in Figure 2, the charging/discharging device of annular furnace of the present invention, comprise: furnace bottom 3 and the drive unit that is opened in charging aperture 22 and the discharging opening 21 on the furnace wall 2, the outside and drives furnace bottom rotation location, this drive unit mainly is made of stepper motor, furnace bottom 3 mainly is made of 90 fan-shaped pink fused alumina stove bricks 30, as Fig. 3 and shown in Figure 5, the surface of every stove brick 30 is provided with twice distributing trough 31, the distributing trough of radially arranging in 180 roads 31 has just evenly been arranged on the surface of whole like this furnace bottom 3, the two ends of distributing trough 31 are respectively arranged with the chamfering 311 that makes things convenient for input and output material---referring to shown in Figure 4, inboard furnace wall 1 offers pusher mouth 11 with the intersection of the radial alignment at discharging opening 21 places, be provided with discharging pusher 4 in the inboard of inboard furnace wall 1, the push rod of discharging pusher 4 is radial arrangement, and activity is located in pusher mouth 11 and the discharging opening 21; The arranged outside charging pusher 5 of wing furnace wall 2 outside, the push rod of charging pusher 5 is radial arrangement and activity is located in the charging aperture 22.In the present embodiment, described charging aperture 22, pusher mouth 11 and discharging opening 21 are along punishment in advance direction conical bore from large to small, the two ends of described distributing trough 31 are provided with chamfering, be equipped with water inlet pipe and return pipe on the described inboard furnace wall 1, water inlet pipe is interconnected with the end of return pipe in stove and is provided with the limited block 6 that matches with charging aperture 22.
The course of work of the present invention is: the charging pusher 5 that is arranged on 2 outsides, furnace wall, the outside pushes steel billet 8 annular furnace from charging aperture 22, be provided with that limited block 6 on the inboard furnace wall 1 can prevent that the end face of steel billet 8 from touching inboard furnace wall 1 and internally the wing furnace wall cause damage, then, hydraulic system drives annular furnace furnace bottom 3 and turns over 2 degree, carry out the charging second time, fill process is identical, repeats no more; When the steel billet that heats 8 arrived discharging openings 21, the push rod of discharging pusher 4 of inboard that is positioned at inboard furnace wall 1 was protruding, from pusher mouth 11 to discharging opening 21 moving process, red-hot steel billet 8 is released annular furnace from discharging opening 21.So improved the speed of charging and discharging greatly, and adapted, made energy-efficient annular furnace in small-sized seamless steel tube production, be used well with effective time that steel billet heats in stove.
