Description

Scrap steel feeding device of intermediate frequency furnace

Technical Field

The utility model belongs to the technical field of the metallurgical casting, concretely relates to intermediate frequency furnace steel scrap feeding device for transport the steel scrap to the intermediate frequency furnace and add wherein.

Background

In steel production using an intermediate frequency furnace as a melting furnace, scrap preheating is not generally performed. I.e. scrap cold is added directly to the furnace. The smelting and feeding of the intermediate frequency furnace are characterized in that the quantity of materials fed in each time is hundreds of kilograms to 4-5 tons according to different furnace volumes, and the feeding is relatively complex; the original intermediate frequency furnace scrap steel feeding adopts the suction cup to directly adsorb and feed into the furnace, so that the smelting period is long, the operation environment is poor, the noise volume is large, the number of workers is large, and the operation intensity is high. Also some intermediate frequency furnaces adopt the feeding trolley to feed in, and the more commonly used mode of feeding trolley is hydraulic pressure turnover type, namely when the feeding trolley moves to near the intermediate frequency furnace, the hydraulic cylinder jacks up the hopper, the hopper rotates around the rotating shaft at the front end, and the scrap steel in the hopper is poured into the intermediate frequency furnace body, but still can't avoid complicated operation to the loading work of feeding trolley.

SUMMERY OF THE UTILITY MODEL

The utility model overcomes prior art's is not enough, provides an intermediate frequency furnace scrap steel feeding device. The problems of poor environment, high noise and high strength of the existing intermediate frequency furnace feeding operation are solved.

In order to achieve the above purpose, the present invention is achieved by the following technical solutions.

The scrap steel feeding device for the intermediate frequency furnace comprises a scrap steel groove, wherein the scrap steel groove is connected with a feeder, and further comprises a large hopper, a small hopper and a walking track, the walking track is arranged above a furnace mouth of the intermediate frequency furnace, the small hopper is arranged on the walking track through a walking part, the small hopper is provided with a walking motor, and the walking motor is used for driving the small hopper to walk on the walking track in a forward and reverse direction; the large hopper is arranged below the feeder and is provided with a vibration motor; the small hopper is positioned below the large hopper.

Furthermore, the feeder is a sucker feeder.

Further, the big hopper is provided with two vibrating motors.

Further, the walking track is a light track.

Further, the small hopper is a hydraulic turnover hopper.

The utility model discloses produced beneficial effect does for prior art.

The utility model feeds materials to the intermediate frequency furnace through the fixed large hopper and the walking small hopper, thereby avoiding the problems of poor operation environment, large noise and large strength caused by the feeding process of the feeding device such as a sucker to the intermediate frequency furnace; the device reduces the environmental influence and the noise influence, is suitable for the characteristic of feeding the intermediate frequency furnace for a small amount of times, and has simple structure, economy and practicality.

Drawings

Fig. 1 is a schematic structural view of the feeding device of the present invention;

in the figure, 1 is a scrap steel tank, 2 is a feeder, 3 is a large hopper, 4 is a small hopper, 5 is a walking track, 6 is an intermediate frequency furnace, and 7 is a vibration motor.

Detailed Description

In order to make the technical problem, technical scheme and beneficial effect that the utility model will solve more clearly understand, combine embodiment and attached drawing, it is right to go on further detailed description the utility model discloses. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. The technical solution of the present invention is described in detail below with reference to the embodiments and the drawings, but the scope of protection is not limited thereto.

As shown in figure 1, the scrap steel feeding device for the intermediate frequency furnace comprises a scrap steel groove 1, wherein scrap steel to be smelted is filled in the scrap steel groove 1; the scrap steel tank 1 is connected with a sucker type feeder 2, and further comprises a large hopper 3, a small hopper 4 and a 15# light walking track 5 with the length of 40 meters, wherein the walking track 5 is arranged above a furnace mouth of the intermediate frequency furnace 6, the small hopper 4 is arranged on the walking track 5 through walking wheels, the small hopper 4 is provided with a walking motor, and the walking motor is used for driving the small hopper 4 to walk on the walking track 5 in the forward and reverse directions; the large hopper 3 is arranged below the feeder 2, and the large hopper 3 is provided with two vibrating motors 7; the small hopper 4 is located below the large hopper 3. The small hopper 4 is a hydraulic turnover hopper.

In the feeder 2 that the scrap steel passes through the sucking disc formula was added big hopper 3, little hopper 4 forward goes and stops big hopper 3 below on walking track 5, start vibrating motor 7 of big hopper 3, the material is in little hopper 4 down, little hopper 4 stops the furnace mouth top of intermediate frequency furnace 6 through the reverse walking of walking motor, start the hydraulic pressure turning device of little hopper 4, it is reinforced to the intermediate frequency furnace 6 in, then little hopper 4 gets back to big hopper 3 below again, continue to connect the material, it is reinforced.

The feeding device feeds materials to the intermediate frequency furnace 6 through the fixed large hopper 3 and the walking small hopper 4, so that the problems of poor operation environment, high noise and high strength caused by the feeding device such as a sucker in the feeding process of the intermediate frequency furnace 6 are solved; the device reduces the environmental influence and the noise influence, is suitable for the characteristic of feeding the intermediate frequency furnace for a small amount of times, and has simple structure, economy and practicality.
