JPS5911634B2 - Cleaning device for leveling mouth and small lid of coke oven - Google Patents

Description

Detailed Description of the Invention This invention provides a new cleaning device for the sealing surface of the leveling port provided at the top of the door that opens and closes the extrusion side port of each oven chamber of a coke oven, and the small lid that opens and closes the leveling port. Its features include the sealing surface 3 of the leveling port 2 provided at the top of the door 1 of the coke oven, the knife edge 5 of the small lid 4 that opens and closes the leveling port 2, and its inner recess 6. Cleaning is performed using a nozzle 8 supported by a laterally movable support member 7 and rotated toward it, and pressurized water sprayed from the nozzle 8.

Seal surface 3 on the front of leveling port 2 and knife edge 5 on the small lid
A large amount of carbon generated during coke kiln adhesion is attached to the inner surface recess 6, and if this is not cleaned and removed each time the lid is opened, gaps may be formed in parts when the lid is subsequently closed and sealed. If the gas leaks out, it will explode.

The present invention provides an optimal cleaning device that ensures this and quickly cleans the area.

To explain in detail with reference to the attached example drawings below, the extruder 9
A support member 7 is installed on a pedestal 10 so as to be movable back and forth and laterally.

Foils 11 are attached to the four front corners of the support member 7, and an endless chino 12 is hung between each of the foils 11.

A motor 13 is connected to one wheel 11, and by rotating this wheel 11, the endless chino 12 is rotated.

Reference numeral 13 denotes a pressure water supply pipe connected to the nozzle 8, which is connected to a pressure water supply section (not shown) via an overspeed interrupter 14.

When the small lid 4 is rotated and opened about the pivot portion 15, the small lid 4 is exposed with its inner surface facing forward.

Then, when the support member 7 on the pedestal 10 is advanced to approach the small lid 4 and directly face it, and the motor 13 is driven, the nozzle 8, which has been supplied with pressurized water, rotates along the endless knife edge 5 and the N pressure Water is jetted to crush and wash away all the carbon attached to the tip surface, inner surface, and inner recess 6 of the knife edge 5, and according to the embodiment, the endless knife edge 5 is completely circled in about 10 seconds to form the knife edge. 5 and the inner recess 6 must be thoroughly cleaned.

Next, the support member 7 is moved laterally to directly face the leveling slot 2, and the motor 13 is started again there.

The sealing surface 3 on the front surface of the leveling opening 2 receives the knife edge 5, and since it has the same size as the endless knife edge 5, the nozzle 8 rotates along the sealing surface 3 to ensure the seal. The surface 3 is cleaned, and the entire circumference of the seal surface 3 is cleaned in the process of going around the seal surface 3 once.

Thus, the present invention has the effect of providing a cleaning device that reliably cleans the sealing surface of the leveling spout, the knife edge of the small lid, and the surrounding area in a very short time with a simple configuration and operation. .
