Coke oven refractory protective removal device and removal method

Abstract

The invention relates to a coke oven refractory protective removal device and a removal method thereof. The coke oven refractory protective removal device comprises a rocking arm brick splitting vehicle for removing the top bricks at top of a coke oven, a brick separator for stripping the smaller bricks, an ash scar peeling hammer for cleaning large areas of the ash scars on the brick, an ash scarcleaner for cleaning the corner angles, grooves and grooved tongues of the bricks, and a brick scale for quickly distinguishing the similar bricks. The device adopts a set of protective removal apparatuses consisting of five independent components for coke oven removal operation, which can realize the protective separation between the refractory bricks, quick cleaning of the attached ash scars, and rapid classification of the similar bricks, and increases the brick removal yield and increases the work efficiency.

Description

technical field [0001] The invention relates to the technical field of furnace and kiln construction, in particular to a protective removal device and method for coke oven refractory materials. Background technique [0002] For the structural adjustment and industrial upgrading of the coking industry, some of them need to be demolished and rebuilt in different places due to the regional industrial layout. A furnace has more than 20,000 tons of refractory materials and nearly 600 types of bricks. It needs to be protected and dismantled, mud removed, marked, classified and packaged, loaded on a truck and sent to the reconstruction site. In actual construction, there are the following disadvantages: [0003] (1) The over-roof brick in the top area of ​​the coke oven is straddled on the top of the combustion chamber wall. The weight of a single brick is about 30 kg and the height is 205mm. It bears most of the weight of the furnace roof. It must be guaranteed that the over-roof...

AI Technical Summary

Problems solved by technology

During the demolition of overhead bricks, workers use wooden squares as levers to pry the bottom of overhead bricks on the scaffolding platform of the carbonization chamber, which may easily cause bricks to lose corners, or even produce transverse cracks, making them unable to be used again.

[0004] (2) The masonry structure of the coke oven is complex, and there are various types of bricks. Taking the combustion chamber of the coke oven as an example, there are usually dozens of brick types for a single-layer wall, and the wall width gradually changes from the coke pushing side to the coke exiting side. Small, the interior of the wall is divided into several fire passages by multiple partition walls, and the width of the partition walls is reduced by a few millimeters for every three partition walls

During dismantling, most of the brick marks were covered with mud and the serial numbers were disturbed. Bricks with similar shapes but different sizes were difficult to distinguish, and they were easily mixed on the brick boards, resulting in inaccurate material statistics.

[0005] (3) The brick structure of the coke oven basically has groove tongues, and the bricks are meshed together by refractory mud. The working surface is easily damaged, making the demolition yield very low

[0006] (4) There are a lot of gray scars attached to the removed refractory bricks, and the workload of stripping and cleaning is large
