Hot maintenance method at joint of rising pipe and bridge pipe

Abstract

The invention discloses a hot maintenance method at a joint of a rising pipe and a bridge pipe. The method includes the steps: (1) preparing a feeding pallet; (2) opening a coal port after a final stage of coking; (3) blowing dust at the joint of the rising pipe and the bridge pipe by compressed air until cleanness, and compressing the air; (4) kneading slightly hard mud materials doped phosphoricacid into circular dough according to needed depths, and placing the circular dough on the feeding pallet to spray slurry on the circular dough to convey the circular dough; (5) pushing the mud materials to a position needing to be wiped and filled by a wiping and filling shovel and leaning the mud materials, and recovering the feeding pallet; (6) secondly conveying the mud materials to the upperportions of the firstly wiped and filled mud materials by the feeding pallet; (7) repeatedly operating the steps five times to complete operation. The hot maintenance method has the advantages that disassembly and assembly of the rising pipe and the bridge pipe are omitted, replacing costs after fusing are avoided, a lot of labor, material resources and production time are saved, benefits are great considerable, and the hot maintenance method has the advantages that time and labor are saved, maintenance speed is high, and hanging time is long.

Description

technical field [0001] The invention relates to a method for maintaining the thermal state of the junction between a coke oven ascending pipe and a bridge pipe. Background technique [0002] The hot maintenance worker in the coking workshop of the coking company is mainly responsible for the maintenance and repair of the coke oven masonry to ensure that the coke oven masonry is tight and does not leak. During the production process, the lining material at the junction of the riser tube and the bridge tube will fall off, causing the exposed part to burn red and then melted, shortening the service life of the riser tube and the bridge tube. Cause smoke and fire after coal loading, cause environmental pollution, heat consumption, riser pipe and bridge pipe are scrapped and replaced. When replacing, maintenance workers need to cut, dismantle and assemble, cranes are hoisted up and down, hot repairers dig out and replace socket packing, it takes several hours to complete, and th...

Problems solved by technology

During the production process, the lining material at the junction of the riser tube and the bridge tube will fall off, causing the exposed part to burn red and then melted, shortening the service life of the riser tube and bridge tube

Causes smoke and fire after coal loading, environmental pollution, heat consumption, riser pipe and bridge pipe are scrapped and replaced

When replacing, maintenance workers need to cut, disassemble and install, hoist up and down by a crane, and thermal repairers dig out and replace socket packing. It takes several hours to complete, and the labor intensity is high, and the operating environment is harsh, which affects production.

Every time it is replaced, only spare parts need about 50,000 yuan, resulting in a great waste of manpower and material resources
