Tapping switching device

Abstract

The invention discloses a tapping switching device. The tapping switching device is characterized that the tapping switching device comprises a conveying plate, a surrounding plate and side plates; the middle of the conveying plate is provided with a fracturing opening which divides the conveying plate into an upper section and a lower section; the inner side of the lower end of the upper section is connected with an upper guide plate, wherein the included angle between the upper section and the upper guide plate is smaller than 45 degrees; the inner side of the upper end of the lower section is connected with a lower guide plate parallel with the upper guide plate; the connecting position of the lower guide plate and the lower section is in arc transition; the upper end of the surrounding plate and the upper end of the conveying plate are connected; the surrounding plate downwards gradually gets away from and gradually gets close to the lower end of the closing plate; a gap is reserved between the lower end of the surrounding plate and the lower end of the conveying plate to form an outlet; the two side plates are separately located on the two sides of the conveying plate and the surrounding plate; the conveying plate and the side plates define a molten iron main flow channel; the surrounding plate and the side plates define a containing cavity; rotary shafts are separately arranged outside the two side plates; limiting blocks are separately arranged above and below the rotary shafts which are connected with rocker arms; and non-spilling switching can be achieved.

Description

technical field [0001] The invention relates to a switching device for tapping molten iron in metal smelting, in particular to a tapping switching device. Background technique [0002] The metal smelting industry involves the transfer of the extracted molten metal. For example, when making iron, the molten iron should be transferred away with a hopper. The hopper has a certain capacity. After the hopper is full, the hopper needs to be replaced. When the hopper is replaced, the molten iron is discharged. It is more difficult to stop, causing leakage and splashing, which still needs to be solved by technology. Contents of the invention [0003] In order to solve the above problems, the present invention provides a tapping switching device. [0004] The technical solution adopted in the present invention is: a tapping switching device, which is characterized in that it includes a conveying plate, a coaming plate and a side plate. For the upper guide plate with an angle of l...
