Description

A tundish tipping device

technical field

The invention relates to the field of tundish overturning equipment, in particular to a tundish overturning device.

Background technique

After the tundish is poured for a certain number of furnaces, the tundish tipping device must be used to dump out the remaining cold steel, refractory bricks and other slag blocks in the tundish. The existing tundish tipping device usually includes a processing chamber and a tipping machine. The processing chamber 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, put the tundish tank from the inlet through the crane and install it on the tipping machine, then the tipping machine will drive the tundish tank to turn over, and pour the slag in the tundish tank into the tipping pit for accumulation. slag removal. During the above process, a large amount of dust is easily generated when the slag is dumped, which affects the production environment and even pollutes the surrounding environment.

The Chinese utility model patent with the announcement number: CN202097398U discloses a tundish tipping device with a dust removal function. It includes a body of a tundish tipping device. Three walls (that is, tipping pits) are built around the body of the tundish tipping device, and two opposite doors are set on one side to enclose the tundish tipping mechanism on all sides. There are two rails on the top of the wall for moving the movable roof; the inner side of the wall is provided with several water mist nozzles to prevent 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 tipping pit so that the movable movable roof can be opened normally, which occupies a large space. A more serious problem is that in actual production, various steels of different lengths will be mass-produced, so a workshop usually needs to be equipped with multiple intermediate tanks of different lengths, and equipped with multiple tipping pits of different lengths. In order to facilitate management and save space, these tipping pits of different lengths are usually compactly designed side by side. The scheme of the Chinese utility model patent with the announcement number: CN202097398U is only designed for an independent tipping pit and cannot be applied to actual production. When two large tipping pits and small tipping pits are arranged side by side and have different lengths, in order to completely cover the large tipping pit, the length of the movable movable roof shall not be less than that of the large tipping pit. In this way, when covering a small tipping pit with a small length, one end of the movable movable roof must extend beyond the small tipping pit and extend to the sky above the large tipping pit, so that the crane cannot lift the intermediate tank into the large tipping pit or from the large tipping pit. The tipping pit is taken out, thus affecting the normal work of the large tipping pit. (2) A lot of space needs to be reserved in front of the tipping pit, so that the two opposite doors can be opened normally, which takes up a lot of space. In addition, when the tipping device dumps the slag, the slag may directly hit the gate and the wall, or even damage the gate and the wall.

SUMMARY OF THE INVENTION

The present invention provides an intermediate tank tipping device to solve the above problems existing in the prior art.

The present invention adopts following technical scheme:

An overturning device for a tundish tank, comprising a processing room and a first door panel, the processing room is provided with a left-handed overturning pit and a right-handed overturned pit of different sizes, and the top of the left-handed overturning pit is provided with a left inlet, and the above-mentioned right-handed overturning pit is provided with a left inlet. The top of the pit is provided with a right inlet, and the above-mentioned first door panel is arranged on the top of the processing chamber so as to be movable left and right to close the left or right inlet; the first door panel includes an upper door panel and a lower door panel, and the top of the lower door panel is provided with a left limit block And the right limit block, the bottom of one end of the upper door plate is provided with an upper block matched with the left limit block and the right limit block, and the upper block is located between the left limit block and the right limit block.

Further, the side of the above-mentioned left tilting pit is provided with a left outlet, and the side of the above-mentioned right tilting pit is provided with a right outlet; also includes a second door panel, and the above-mentioned second door panel can be moved left and right to be arranged on the side of the processing chamber, for closing the left outlet or the right outlet The second door panel includes a connection door panel and an avoidance door panel, the upper end of the connection door panel is arranged on the side of the processing chamber so as to be movable left and right, and the lower end is provided with the avoidance door panel that can be turned back and forth.

Further, it also includes a rubber sheet, and the left and right edges of the inner side of the second door panel are provided with the aforementioned rubber sheet.

As can be seen from the above description of the structure of the present invention, compared with the prior art, the present invention has the following advantages:

First, the present invention includes a first door panel for closing the left or right inlet, and the first door panel is composed of an upper door panel and a lower door panel that can move with each other. When moving to the left and above the left entrance, the overlapping area of the upper door panel and the lower door panel is more, and the actual length of the first door panel is shorter and just fits the left entrance; when moving to the right and above the right entrance, the upper door panel and The overlapping area of the lower door panel is less, 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 the left inlet (or right inlet) is closed, it will not affect the right inlet (or left inlet). import) to carry out the hoisting operation of the intermediate tank.

Second, in the present invention, the second door panel includes a connection door panel and an avoidance door panel; the upper end of the connection door panel can be hung in the processing room so as to be movable left and right, and the avoidance door panel is arranged on the lower end of the connection door panel so as to be flipped back and forth. When the slag in the intermediate tank falls and hits the lower part of the second door panel, that is, the avoidance door panel, the avoidance door panel can be rotated independently to relieve the force of the slag block impact on the connecting door panel and prevent the second door panel, the second door panel and the processing chamber. The sliding mechanism is damaged.

Third, in the present invention, rubber plates are provided on the left and right edges of the inner side of the second door panel, so that the side of the processing chamber and the second door panel are closely attached, and the tilting device can form a closed space to prevent the dust from spreading outward and improve the dust removal effect.
