Description

Technical Field

[0001] The invention relates to the field of intermediate tank tipping equipment, in particular to an intermediate tank tipping device. Background Art

[0002] After a certain number of furnaces have been poured, the tundish must be tipped out using a tundish tipping device to dump out the cold steel, refractory bricks and other slag blocks remaining in the tundish. The existing tundish tipping device usually includes a processing room and a tipping machine. The processing room is provided with at least one tipping pit. Each tipping pit is provided with an inlet at the top, a tipping machine is installed inside, and an outlet is provided on the side. First, the tundish is placed in from the inlet by a crane and installed on the tipping machine. The tipping machine then drives the tundish to flip, and the slag blocks in the tundish are poured into the tipping pit for accumulation. Finally, the slag blocks in the tipping pit are removed by a forklift or manually. A large amount of dust is easily generated when dumping the slag blocks in the above process, which affects the production environment and even pollutes the surrounding environment.

[0003] The Chinese utility model patent with announcement number: CN202097398U discloses an intermediate tank tilting device with dust removal function. It includes a body of an intermediate tank tilting device, three walls (i.e., tilting pits) are built around the body of the intermediate tank tilting device, and two opposing doors are set on one side to surround the intermediate tank tilting mechanism on all sides. Two tracks are set on the top of the wall for moving the movable roof; the inner side of the wall is provided with a number of water mist nozzles for preventing dust from rising. This scheme has the following shortcomings: (1) A large amount of space needs to be reserved on the right side of the tilting pit so that the movable roof can be opened normally, which occupies a large space. A more serious problem is that since various steels of different lengths will be mass-produced in actual production, a factory building usually needs to be equipped with multiple intermediate tanks of different lengths and multiple tilting pits of different lengths. In order to facilitate management and save space, these tilting pits of different lengths are usually designed to be compactly arranged side by side. The scheme of the Chinese utility model patent with announcement number: CN202097398U is designed only for an independent tipping pit and cannot be applied to actual production. The specific principle is as follows: Assuming that the scheme of the Chinese utility model patent with announcement number: CN202097398U is applied to two large tipping pits and small tipping pits arranged side by side and of different lengths, in order to completely cover the large tipping pit, the length of the movable roof must not be less than that of the large tipping pit. In this way, when covering the small tipping pit with a shorter length, one end of the movable roof must exceed the small tipping pit and extend to the sky above the large tipping pit, resulting in the crane being unable to lift the intermediate tank into the large tipping pit or take it out of the large tipping pit, thereby affecting the normal operation of the large tipping pit. (2) A large amount of space needs to be reserved in front of the tipping pit so that the two opposing doors can be opened normally, which occupies a large space. In addition, when the tipping device dumps the slag blocks, the slag blocks may directly hit the door and the wall, and even damage the door and the wall. Summary of the invention

[0004] The present invention provides a tundish tipping device to solve the above problems existing in the prior art.

[0005] The present invention adopts the following technical solution:

[0006] A tundish tilting device comprises a processing chamber and a first door panel, wherein the processing chamber is provided with a left tilting pit and a right tilting pit which are arranged left and right and of different sizes, the top of the left tilting pit is provided with a left inlet, the top of the right tilting pit is provided with a right inlet, the first door panel is movably arranged left and right on the top of the processing chamber for closing the left inlet or the right inlet; the first door panel comprises an upper door panel and a lower door panel, the top of the lower door panel is provided with a left limit block and a right limit block, the bottom of one end of the upper door panel is provided with an upper stopper matched with the left limit block and the right limit block, The upper stop block is located between the left limit block and the right limit block, a left exit is provided on the side of the left tilting pit, and a right exit is provided on the side of the right tilting pit; it also includes a second door panel, which can be movably arranged on the side of the processing chamber to close the left exit or the right exit; the second door panel includes a connecting door panel and an avoidance door panel, the upper end of the connecting door panel can be movably arranged on the side of the processing chamber to close the left exit or the right exit, and the lower end can be flipped forward and backward to be provided with the avoidance door panel, and it also includes a rubber plate, and the left and right edges of the inner side of the second door panel are provided with the rubber plate.

[0007] From the above description of the structure of the present invention, it can be seen that compared with the prior art, the present invention has the following advantages:

[0008] First, the present invention includes a first door panel for closing the left inlet or the right inlet, and the first door panel is composed of an upper door panel and a lower door panel that can move relative to each other. When moving to the left to above the left inlet, the upper door panel and the lower door panel have a larger overlapping area, and the actual length of the first door panel is shorter and just fits the left inlet; when moving to the right to above the right inlet, the upper door panel and the lower door panel have a smaller overlapping area, and the actual length of the first door panel is longer and just fits the right inlet. It can be seen that the first door panel adopts a segmented design to achieve automatic length adjustment, so that it can be applied to left and right inlets of different sizes, and when closing the left inlet (or right inlet), it will not affect the lifting operation of the intermediate tank at the right inlet (or left inlet).

[0009] Secondly, the second door panel in the present invention includes a connecting door panel and an avoidance door panel; the upper end of the connecting door panel can be movably hung on the processing chamber, and the avoidance door panel can be flipped forward and backward and arranged at the lower end of the connecting door panel. When the slag in the intermediate tank falls and hits the lower part of the second door panel, i.e., the avoidance door panel, the avoidance door panel can rotate independently to alleviate the force of the slag hitting the connecting door panel, and prevent the second door panel and the sliding mechanism between the second door panel and the processing chamber from being damaged.

[0010] Thirdly, the present invention provides rubber plates on the left and right edges of the inner side of the second door panel, so that the side of the processing room and the second door panel are in close contact, and the tipping device can form a closed space to prevent dust from spreading outward and improve the dust removal effect.
