Description

Technical Field

[0001] The utility model relates to the technical field of furnace charge conveying, in particular to a furnace charge dropping and rotating device. Background Art

[0002] Submerged arc furnace is also called arc furnace or resistance furnace. It is mainly used for reducing smelting ore, carbonaceous reducing agent and solvent and other raw materials. The ore and other catalytic materials added to the smelting furnace are collectively referred to as charge. Since the charge needs to be transported from the ground to the top feed port of the submerged arc furnace for feeding, during the feeding process, the charge car moves to the hopper through the track, and the charge car is dumped into the hopper for temporary storage. The hopper is then accurately fed by the vibrating feeder. When there is a lot of charge in the charge car, the charge will be scattered at the front and rear ends of the charge port during the dumping process. The spilled charge not only affects the surrounding environment, but also poses a safety risk to operators who are close to it. The scattered charge is around the equipment and needs to be cleaned up regularly by operators. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a furnace charge dropping and rotating device, through which protective nets are set at the positions at the front and rear ends of the hopper where materials are easily scattered. The protective nets are used to receive the furnace charges that fall from both ends and collect them in a centralized manner, preventing operators from having to handle the charges again after they fall, thus avoiding the safety hazards caused by the charges falling from the front and rear ends.

[0004] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

DETAILED DESCRIPTION

[0018] like Figure 1 , 24 shows a furnace charge drop and rotation device, which mainly uses a supporting frame 1 as a carrier; a top plate 1.1 is fixed on the top of the supporting frame 1; side plates 1.2 are fixed on the three sides of the supporting frame 1 close to the top, and the side plates 1.2 are used for protection and can be used as supports for fixed connection of support members 7. One side has an opening for rail 11 to feed materials; a vibrating feeder 3 is suspended on the inner side of the supporting frame 1; a feeding hopper 2 is fixed above the vibrating feeder 3; protective grids 4 are symmetrically provided at the front and rear ends of the hopper 2 along the feeding direction; guide rods 5 are fixed at the four corners of the bottom of the protective grid 4; springs 6 are sleeved on the guide rods 5; support members 7 are fixed to the side plates 1.2 corresponding to the positions of the protective grids and the back of the aggregate box 8; the guide rods 5 at the four corners are movably inserted on each support member 7; a vibration motor 9 is fixed at the bottom of the protective grid 4, and the vibration motor 9 can be used to assist in vibration feeding when the material is not discharged smoothly. Furthermore, a horizontal plate 10 is fixed to the bottom of the protection grid 4 ; the vibration motor 9 is fixed on the horizontal plate 10 .

[0019] like Figure 1 , 3 As shown in Figures 4 and 5, a collection box 8 is fixed on one side of the supporting elevated frame 1; two openings are provided on the top of the collection box 8, and the two openings correspond to the discharge ends of the protective grid 4 at the front and rear ends respectively; a discharge port 8.2 is provided at the bottom of the collection box 8; the collection box 8 is a U-shaped structure, and two feed ports 8.1 are provided on the top of the collection box 8; the bottom of the collection box 8 gathers toward the middle, and the discharge port 8.2 is below the gathering position, and a flap valve is provided at the discharge port 8.2; a conveyor belt for conveying furnace materials is provided below the discharge port 8.2; the conveyor belt returns the collected materials to the loading place. In order to prevent the collection box 8 from affecting the operation of the vibrating feeder 3, a vibration gap is reserved between the vibrating feeder 3 and the collection box 8. A track 11 for feeding from the ground is provided obliquely on one side of the supporting elevated frame 1 where the opening of the track 11 is left for feeding, and a feeding car 12 moving along the track 11 is provided on the track 11, and the feeding car 12 is dragged by a traction rope. The feed rail is part of the existing equipment in our factory and has not been modified. It is only briefly explained because of the association. If the fixing method is not introduced separately in the above, it is welded or threaded using the common technical means used by technicians in the industry.

[0020] Here’s how it works:

[0021] The loading vehicle 12 moving from the track 11 loads the materials. After the loading vehicle 12 reaches the feeding point, it starts to dump the materials. During the dumping process, the vibrating feeder 3 vibrates. Because the hopper 2 is wide on the left and right but narrow on the front and rear ends, the shaking of the hopper 2 easily spills the materials from the front and rear ends. The spilled materials fall on the protective grid 4 and finally enter the collection box 8. Once the protective grid 4 fails to discharge the materials smoothly, the vibration motor 9 can be used to assist the discharge. The materials on both sides are collected in the collection box 8 and transported back to the feeding point through the conveyor belt to be re-loaded.

[0022] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
