Description

[Detailed description of the invention] This invention is a coke oven riser pipe lid water sealing device,
In particular, the present invention relates to a device for preventing water sealing water from scattering.

Generally, a lid that can be opened and closed is attached to the top of the riser pipe in a coke oven. When the lid is closed, it is desirable to maintain a complete seal with respect to the riser pipe in order to prevent deterioration of the working environment due to gas leakage. A water seal structure is known as a seal structure for this riser lid. In this method, the peripheral end of the lid is accommodated in a concave circumferential groove formed at the top of the riser pipe, and water is further supplied into the concave circumferential groove to form a water reservoir, thereby providing a water seal. The water that overflows the water reservoir is sent to the next process through drain ports and drain piping provided at appropriate positions around the circumference.

However, in the above-mentioned water sealing equipment for the riser pipe lid, hot water is always stored in the water reservoir at a depth of about 8 cm, so when trying to close the lid,
Some of this hot water tends to scatter due to internal gas pressure, etc., and there are problems that need to be improved in terms of safety and workability.

In view of the above points, an object of the present invention is to provide a device that has a simple structure and prevents water seal water from scattering in a water seal part. To achieve this purpose, the device of the present invention has the following features: (1) An opening is opened in the pit part communicating with the water sealing water reservoir at a position slightly higher than the lower end of the riser pipe lid when closed, and a riser is opened at the tip of the opening. A water seal for a coke oven riser pipe lid, consisting of a drain pipe equipped with a water seal that attaches and detaches in conjunction with the opening and closing of the pipe lid, an overflow pipe that opens at a higher position than the opening of the drain pipe, and a water supply pipe. It is a device.

The present invention will be explained below based on embodiments shown in the drawings. Fig. 1 is a front view showing one embodiment of the device of the present invention, Fig. 2 is a side view of the same, Fig. 3 is an enlarged vertical cross-sectional view of the pit portion in Fig. 1, and Fig. 4 shows the lid in Fig. 3. A diagram showing the open state, Figure 5 is the same as Figure 1 A-A
An enlarged line cross-sectional view, Figure 6 is a plan view of Figure 5, and Figures 7-
FIG. 9 is an enlarged vertical cross-sectional view of a pit portion in another embodiment. In the figure, 2 is the lid, 3 is the pit, 4 is the water seal, 7 is the rising pipe, 8 is the drain pipe, 17
is a water seal.

1 and 2, the water seal device according to the present invention has a water seal water reservoir (hereinafter simply referred to as a reservoir) 4 in a concave circumferential groove provided on the circumference of the upper end of the riser pipe 7.
As shown in FIG. 5, the lid 2 is composed of a lid 2 whose peripheral edge is bent so as to be inserted into a reservoir 4, and is sealed against water by supplying water to the reservoir 4.
The lid 2 is opened and closed by operating a lid support arm 1 which rotates about a support shaft 10.

In FIGS. 3 to 6, the pit section 3 is box-shaped, has a drain pipe 8 that opens upward, an overflow pipe 9, and a water supply pipe 5, and is installed on the side of the reservoir section 4. . The position of the opening of the drain pipe 8, when the lid 2 is closed, is lower than the height that is usually 20 m/m higher than the position where the peripheral edge of the lid 2 is located, preferably in a range of 10 to 20 m/m higher. For example, there is no scattering of hot water, and the replenishment time to reach the appropriate water level is short.

A cap-shaped water sealing device 17 of a size capable of sealing the opening is placed at the opening of the drain pipe 8. The pit portion 3 communicates with the reservoir portion 4 at a position that is the same as or lower than the opening of the drain pipe 8.

The water sealing tool 17 is connected by a chain 13 to an operating rod 12 that is rotatably supported by a support shaft 14 . Operation stick 12
has a length such that the end on the side to which the chain 13 is connected comes into contact with the stopper 11 fixed to the lid 2, and the opposite end has a length that allows the operation stick to come into contact with the stopper 11 when the contact with the stopper 11 is released. A weight 15 having a weight necessary to rotate 12 clockwise about a support shaft 14 is attached. The angle at which the operating rod 12 rotates to the right is
The selection is made by adjusting the distance at which the left side of the weight 15 contacts the right side surface of the pit portion 3. Control stick 1
2 and the chain 13 vary depending on the installation position of the pit part 3, but the water sealing device 17 leaves the opening of the drain pipe 8 when the lid 2 is opened, and is placed at the opening when the lid 2 is closed. The length is selected to be the desired length.

Water sealing in the device of the present invention constructed as described above is performed as follows. When the lid 2 is closed as shown in FIGS. 1 to 3 and 5 to 6, the water sealing device 17 is placed at the opening of the drain pipe 8, so water is not supplied from the water supply pipe 5. water seal water 1
6 is in the reservoir portion 4, and the reservoir lid 2 is sealed with water. In order to compensate for the decrease in the water seal due to evaporation, it is desirable to supply water from the water supply pipe 5 to such an extent that a small amount of water always overflows from the overflow pipe 9.

Next, when the lid 2 is opened, the stopper 11 is removed from the operating rod 12 as shown in FIG. and water sealing tool 1
7 is raised. The water sealing water 16 in the pit portion 3 and the reservoir portion 4 is discharged from the removed opening of the water sealing device 17 until it reaches the height of the opening. In this case, it is desirable to close the valve 6 and stop the water supply.

Thereafter, the lid 2 is closed, but since the water level of the water seal 16 has fallen, the water seal does not scatter even if the peripheral edge of the lid 2 comes into contact with the water seal.
Then, the water sealing device 17 is placed again on the opening of the drain pipe 8 to seal the opening, so that the water supplied from the water supply pipe 5 fills the pit part 3 and the reservoir part 4, and the lid 2 is closed. Water sealed.

Although the method for attaching and detaching the water sealing tool 17 using the operating rod 12 and the chain 13 has been described above, it can be done using a wire instead of these. For example, in FIG. 7, one end of the wire 19 is connected to the water sealing device 17.
This is a case where the other end 18 is fixed to the lid 2 after passing through the ring 20 fixed directly above the water sealing device 17. Figure 8 shows the ring 20 in Figure 7.
This is a case where a pulley 21 is used instead. 9th
The figure shows a case where the other end 18 of the wire 19 is fixed to a groove of a pulley 23 that is pivotally attached to the support shaft 10. In FIG. 9, when the operating arm 24 is pushed down to open the lid 2, the support shaft 10 and the pulley 23
rotates to the left, so the water sealing tool 17 is pulled up. The actuating arm 2 is then activated to close the lid 2.
4 is pushed up, the support shaft 10 and pulley 23 are rotated to the right, so that the water sealing device 17 returns to its old position and the opening is sealed.

The shapes of the water sealing device 17 and the opening of the drain pipe 8 may be such that when the water sealing device 17 comes into contact with the opening, the opening is sealed, and when the water sealing device 17 is separated from the opening, the opening is opened. For example, an inverted conical closure 22 as shown in FIG. 8 and an opening shaped to fit therewith, or a sideways opening as shown in FIG. 10 and an upper end of the opening are often used. It is also possible to use a water sealing tool 26 that is movable up and down using a fixed shaft 25 as a fulcrum.

As detailed above, the device of the present invention lowers the water level of the water seal when the lid is opened and lowers the water level when the lid is closed by attaching and removing the water sealing device to the opening of the drain pipe according to the opening and closing of the lid. Because of its simple structure, the water level can be reliably adjusted even in environments with high temperatures and a lot of dust, making it useful as a riser pipe lid water sealing device.
