Problems solved by technology

[0003] The existing side-suction smoke guide vehicles only have two-station positive guide methods, and the side-suction smoke guide cannot be realized for the end carbonization chamber. Generally, manual opening and closing of the furnace cover is used, and the labor intensity of the operators is high, and the production efficiency is low.

Abstract

The invention discloses a grasping claw of a four-station side-draft smoke guide vehicle of a coke oven. A flange plate is arranged at the upper end of a lifting sleeve, and a fireproof plate is arranged at the lower part; a lifting rod is arranged in the lifting sleeve; a connection plate is arranged at the upper end of the lifting rod, and an ear claw limiting sleeve is arranged at the lower end; on an uncovering smoke guide device of the four-station side-draft smoke guide vehicle of the coke oven, a left ear claw is connected with the left side and a right ear claw is arranged on the right side; and the upper ends of the left ear claw and right ear claw are in lap joint with the ear claw limiting sleeve. According to the grasping claw disclosed by the invention, the left ear claw and the right ear claw are adopted and mounted on the uncovering smoke guide device of the four-station side-draft smoke guide vehicle of the coke oven by a connecting shaft; the left ear claw and the right ear claw rotate around the connecting shaft to form a lever; a power element is in lap joint with the upper ends of the left ear claw and right ear claw through the lifting rod, and pushes the left ear claw and right ear claw open or close; and a top cover of a carbonization chamber is clamped to move so that the top cover of the carbonization chamber can open and close. The grasping claw disclosed by the invention has the advantages of reasonable design, simple structure, high mechanization degree, low labor intensity of operators, high production efficiency and the like, and can be popularized and applied to a coke oven.

Description

technical field [0001] The invention belongs to the technical field of coking production equipment or devices, and in particular relates to a device for leading out flue gas in a carbonization chamber. Background technique [0002] Coking production is to put coal cakes that have been tamped in a certain proportion into the carbonization chamber from the side of the machine through the coal loading car. Coal cake decomposes in the carbonization chamber to isolate the gas generated during the air heating process, spray ammonia water at the bridge pipe and gas collecting pipe to generate negative pressure, and guide the gas from the top space of the carbonization chamber to the gas system through the rising pipe, bridge pipe, and gas collecting pipe. However, when the briquettes are pushed into the carbonization chamber, the door of the coke oven is completely opened, and the outside air enters the carbonization chamber under the action of the system suction of the gas collect...
