Rapid replacing method for coke grid of coke barrier vehicle of large-scale coke furnace

Abstract

The invention relates to the vehicle maintenance method field applied in equipments for producing gas, coke, tar or analogs by carbonizing carbonaceous materials, and concretely relates to a rapid replacing method for a coke grid of a coke barrier vehicle of a large-scale coke furnace. The invention provides a rapid replacing method for the coke grid of the coke barrier vehicle of the large-scale coke furnace, the method can be performed after the coke barrier vehicle stops operation. The method comprises the following steps: a. sweeping the dust, b. positioning a coke car, c. setting a track, d. connecting a chain hoist, e. dismounting the connection, f. moving the coke grid, g. replacing the old component, h. integrally installing and i. arranging an accessory, wherein the nine steps are performed in order. The invention has the advantages of simple steps, convenient operation, short construction cycle, less production influence and high production efficiency.

Description

technical field [0001] The invention relates to the field of vehicle maintenance methods operating in equipment for producing gas, coke, tar or the like by dry distillation of carbonaceous materials, in particular to a rapid replacement method for coke guide grids of large-scale coke oven coke arresting vehicles. Background technique [0002] Coke oven, also known as coke oven, is the equipment for coal coking and the key to coking technology. The body of modern coke oven is composed of three main parts: carbonization chamber, combustion chamber and regenerator. Usually, the effective volume is 30m 3 The above are called large coke ovens. The dimensions of large coke ovens widely used at present are: the carbonization chamber is 6m to 7.5m high, 15m to 17m long, and the average width is 0.4m to 0.46m, with an effective volume of more than 50m 3 . The coke-stop car is an important equipment in the coke oven. The coke-stop car runs on the coke side of the coke oven. It is us...

AI Technical Summary

Problems solved by technology

The coke stop car consists of driving mechanism, hanging roller, side roller, coke guide grid, upper guide rail, lower guide rail, anti-tipping mechanism, dust removal plate group, coke guide groove, locking mechanism, head dust-proof device, and coke-proof mechanism , locking limit, etc., in which the steel structure body of the coke guide grid bears the high temperature of coke during operation, which will cause structural deformation after long-term use, resulting in frequent accidents during operation, such as jamming of the coke guide grid back and forth, center The line limit is out of control, etc., then it must be replaced

However, due to the large volume and mass of the coke guide grid of the coke-carrying vehicle of the large-scale coke oven, the construction progress is slow and takes more than 3 days, which cannot meet the needs of fast-paced production.
