Abstract

The utility model relates to a feeding barrel, which is particularly suitable for feeding various furnaces such as induction electric furnaces. It is mainly composed of a barrel body, a fan-shaped bottom plate with a rotating arm, locking rollers, brackets, lifting rings and guide blocks. When the bottom of the bucket is closed, the fan-shaped bottom plate is buckled upside down on the lower end of the bucket body in a pyramid or conical shape, and locked by corresponding rollers. When unloading, the rollers move out automatically, and the fan-shaped bottom plate opens for feeding. Its characteristics are: it can ensure the central feeding, change the height of the unloading point and adjust the unloading speed according to the requirements, so as to ensure that the material does not hit the furnace wall and eliminate the splashing of molten metal.

Description

Charing pail

The utility model belongs to metallurgical machinery class charging (feeding) equipment, is mainly used in the reinforced work of various smelting furnaces such as electric induction furnace.

At present aborning, the lump material charging bucket of various smelting furnaces has single bottom opened, two bottom opened and convertible three kinds.In use all there are some shortcomings in these charging buckets.Single bottom opened and convertible charging basket are to the smelting furnace discharging time, and material adds from smelting furnace one side, and reinforced inhomogeneous and speed is difficult to control, not only expect easily bump and damage the furnace wall of piece, reduce stove service life, and can cause that molten metal splashes.Two bottom opened charging baskets are when discharging, and water conservancy diversion can only be carried out a horizontal direction to material in the bucket end, and the material that bucket both sides, the end are unloaded still easily clashes into the furnace wall.In addition, can all open at the bottom of making two barrels, the height apart from the stove upper limb must be greater than the maximum radius of turn at the bottom of the bucket at the bottom of the bucket during discharging, and therefore, the emptying point is higher, and molten metal splashes still more serious.

The purpose of this utility model is to avoid above-mentioned weak point of the prior art that a kind of centre charging bucket is provided.

The purpose of this utility model can reach by following measure: suspension ring and two or more guide pads are housed on staving, inverted pyramid that fan-shaped base plate constituted or inverted cone that employing has pivoted arm are the bucket end, base plate connects for movable with staving, the locking roller is housed on support, is used for locking respective base.

The utility model has following advantage compared to existing technology:

1, because the bucket end for by inverted pyramid or inverted cone structure that several fan-shaped base plates constituted, has guaranteed the centre charging of reinforced stove, make material not clash into the furnace wall.

2, because fan-shaped base plate has pivoted arm, not only can regulate the emptying point height, and can control discharge rate, eliminate the phenomenon that molten metal splashes.

Fig. 1 is the front view of a kind of embodiment of the utility model.

Fig. 2 is the vertical view of the foregoing description.

Below in conjunction with accompanying drawing the utility model is further described.

As shown, this charging bucket can by support 1, drum shape staving 7, six hinges be contained in staving 7 bottoms the fan-shaped base plate 2 that has pivoted arm 4, be contained in six locking rollers 3 being used for locking base plate 2 on support 1 framework, be contained in six guide pads 6 on staving 7 tops and suspension ring 8 etc. and form.Pivoted arm 4 can be angle greater than 90 ° V-type member, also can do angled greater than 90 °, Yi Bian and wherein be the member of curved shape, pivoted arm 4 is fixing with base plate 2, and relative position is adjustable.

Before charging basket charging, preferably charging basket is hung and is sitting on the spill seat, force that six fan-shaped base plates 2 are closed, pivoted arm 4 opens, thus six locking rollers 3 and support 1 deadweight fall, make roller 3 be absorbed between corresponding pivoted arm 4 an and the bucket outer wall and locking bucket end.The material piece that to weigh then adds in the charging basket.Need when smelting furnace is reinforced, the charging basket that the material piece at first will be housed winches to the smelting furnace top and aligns fire door.In the handling process, because the support locking effect of roller 3, the bucket end, can not open automatically.When in stove, feeding in raw material, the charging basket that lands gradually, in the process that descends, support 1 is owing to platform around its six legs elder generation contact fire doors stops.Charging basket then continues to descend, and this moment, roller 3 relatively scrolled up in the vertical section and staving 7 outside wall portions of fan-shaped base plate 2 with pivoted arm 4 interlockings, and fan-shaped base plate 2 can not be opened.Shift out pivoted arm 4 vertical sections and after entering tilting section up to roller 3, just forcing six fan-shaped base plates 2 to rotate under the effect of material deadweight and around trend, opening and carry out discharging.Discharge rate is controlled by the speed that charging basket descends in the certain back of angle of pivoted arm 4.The height in beginning emptying point is not only controlled by the height of support 1, also can regulate with the length of pivoted arm 4 vertical sections by changing fan-shaped base plate 2.Discharging is finished, and pivoted arm 4 tilting section upper surfaces go to locking roller 3 belows, and guide pad 6 drops on the support 1.The locking roller 3 of slinging behind the charging basket is not closed at the bottom of can not falling into automatically and making between pivoted arm 4 and staving 7 outer walls barrel, thereby guarantees that material unstows.In order to prevent the charging basket rotation, on support 1, one or a pair of guide plate 5 can be housed with corresponding section, guide plate 6 position.

Claims

1. A feeding barrel, equipped with a lifting ring (8) and two or more guide blocks (6) on the barrel body (7), characterized in that:
