Description

TECHNICAL FIELD

[0001] The utility model relates to coal chemical and mechanical equipment technical field, especially a rising pipe base replacement device. BACKGROUND

[0002] The coking process of the ironworks has four coke ovens, and each coke oven has a corresponding carbonization chamber and a rising pipe. The rising pipe is mainly composed of a bridge pipe, a water seal, a rising pipe cylinder, a base and an ammonia water pipeline system, and is mainly used for guiding the flow of raw gas generated in the carbonization chamber.

[0003] The base of the rising pipe gradually ages and falls off under the high-temperature roasting of the carbonization chamber, and the cast iron shell on the outside carbonizes and melts off. Under normal operation of the coke oven, smoke appears. Since the 3# and 4# coke ovens are damaged first, the rising pipe is designed on the machine side, the distance from the machine side to the ground is relatively close, and the ground has the construction operation conditions of a 75-ton and below automobile crane. Therefore, the automobile crane is used to replace the base of the rising pipe. The rising pipe of the 1# and 2# coke ovens is designed on the coke side, although the distance from the coke side to the ground is relatively close, but it does not have hoisting conditions. Therefore, hoisting needs to be carried out on the machine side. Since the space span is far away, only a 180-ton automobile crane can meet the hoisting requirements. According to the mode of using the 180-ton automobile crane, the operation can be carried out at the edge of the coke oven. Since the passing height of the SCP machine is lower than the body height of the 180-ton automobile crane, the SCP machine needs to be moved to one side at the middle position. It takes 2 hours to stretch and retract the rod in front and back of the 180-ton automobile crane, and to load and unload the counterweight. The hoisting operation time for replacing the base needs 3 hours, and the total time needs 5 hours, that is, from the entry of the crane to the exit of the crane in the oven area, it needs 5 hours. This means that the coke in the carbonization chamber of the coke oven cannot be pushed out, causing the production to be suspended.

[0004] Therefore, after optimizing the operation mode, the patent proposes a rising pipe base replacement device, which can cancel the use of a large crane and reduce the maintenance intensity, improve safety protection, and ensure the smooth production of the coke oven. Utility model content
