ているのが一般的である。(Prior Art) In the operation of a chamber-type coke oven, after the carbonization is completed, the red hot coke is kiln-fired, the furnace lid is closed, and new carbonization is performed from the coal-charging car at the top of the furnace. However, in order to prevent coal dust from the vicinity of the charging port from leaking to the outside air, dust and gas are sucked into the dry main by the ejector effect of the low water nozzle provided at the curved pipe. Moreover, since the air in the carbonization chamber of a volume commensurate with the carbonization is rapidly discharged during carbonization, high-pressure ammonium hydroxide is used to increase the ejector effect. In addition, at the time of normal gas generation, low-pressure ammonium hydroxide is generally used because the gas temperature is lowered and a weak ejector effect is sufficient.

With the lever opening / closing device, it can be switched by rotating the air valve fixed to the top of the furnace. Conventionally, the lever itself directly provided on the air valve is pressed by the striker on the coal car side. Has become.

頻度が高くなっている。(Problems to be solved by the invention) As described above, since the striker on the side of the coal car hits the lever provided on the air valve directly in the past, when the position of the coal car to be stopped is rough. In particular, a regular force is applied to the mounting base part of the thin lever of the air valve, and the frequency of accidental breakage of the lever is high.

A plurality of levers are arranged on the shaft portion, and the shaft portion is positioned between two metal plates which are fixed to an appropriate support and are orthogonal to the axis of the air valve. We propose the structure of the air valve for switching high and low pressure low water. According to the device of the present invention, even if the stop position of the opening / closing device on the side of the coal car is slightly deviated from the normal position, no abnormal force is applied to the air valve.

としては鋼板が好ましい。(Operation) A feature of the present invention is that a shaft portion connected by a fitting is provided at an extended position of the shaft center of the air valve, and a lever attached to the shaft portion is operated by an opening / closing device provided on the coal car side. Since the shaft center of the air valve and the shaft equipped with the lever for rotation are indirectly connected, the force applied to the lever does not directly affect the air valve, and the shaft part with the lever is attached. Is positioned so as to be sandwiched between two rigid metal plates that are arranged orthogonally to the axis of the air valve, so even if the striker pushes the position slightly, only a vertical force is applied to the shaft. That is what I was supposed to do. As described above, since the mounting position of the lever on the shaft portion is located at the intermediate portion of the two metal plates orthogonal to the axis of the air valve, the two metal plates are replaced with a metal plate thicker than the thickness of the lever. By doing so, the lever rotates the air valve from the direction perpendicular to the axis in any case. Therefore, according to the device of the present invention, even if a slight force is applied to the shaft of the lever as long as the lever is rotated, the air valve is not affected at all. If the stop position of the lever opening / closing device of the coal car is significantly deviated from the normal position, the lever cannot be rotated by the force of the striker.
No regular force is applied to the base portion of the lever as in the conventional case, the air valve is completely unrelated, and the lever of the present invention is not broken as in the conventional case. The materials of the two metal plates are not particularly limited as long as they have rigidity, but steel plates are preferable from an economical point of view. The member for supporting the two metal plates may be either a steel plate or a steel pipe, and it is necessary to fix one end at an appropriate position on the furnace top. A steel plate is preferable as the material.

ばどのような方式をとってもよい。On the other hand, the lever opening / closing device is not particularly limited as long as it is a mechanism that can be pressed from the coal car side, and any system may be used as long as it can advance the striker by using a hydraulic mechanism or the like.
