Description

Intelligent building machine for coke oven and continuous building process for coke oven

Technical Field

The invention relates to the technical field of coke oven masonry equipment, in particular to an intelligent masonry machine for a coke oven and a continuous masonry process for the coke oven.

Background

The coke oven as the most complicated industrial kiln is mainly built by silica bricks and clay bricks, and relates to over 1000 brick types, wherein most of the brick types are special-shaped bricks, and the mass of each refractory brick is different from 1kg to 30 kg. The coke oven has a very complex structure, and consists of a plurality of areas such as a regenerator, a chute area, a combustion chamber, a furnace top area and the like, but the structure of each area is designed or constructed by taking a layer as a unit. The brick shape of each layer has a fixed thickness and is built in a specific arrangement mode. Taking the furnace type of a coke oven with 6m which is common in China at present as an example, the design layer number is about 100 layers, and the masonry period of a single newly-built coke oven is overlong by adopting the conventional manual masonry mode.

By adopting a traditional manual building mode, building constructors for building a newly-built coke oven need to search related brick types of each layer in a refractory material warehouse from the beginning of conveying the brick types (loading bricks), then convey the brick types to a building place through a crane or a portal frame, and finally dry all the brick types at the building position according to the arrangement sequence of drawings by building workers. Although the conveying process is carried out by a mechanical device, the arrangement of each refractory material needs to be manually realized.

During formal masonry, firstly, operations such as bracing wires, ink jet lines and the like are required to be carried out so as to restrict the size of the masonry; then, each masonry worker needs to pick up the refractory bricks placed in advance, and plasters the bonding surface by using a trowel, and the requirement of mortar joints is different from 3mm to 8 mm. And after plastering, the refractory bricks are placed to a specific position again and compacted, so that no gap exists between the bricks.

After one section brickwork of completion is built by laying bricks or stones, still need the workman to adjust the horizontal and high roughness of brickwork through level bar and guiding rule, prevent that the size from appearing the deviation. In addition, in the whole building process, other building workers are required to repeatedly extract mortar from the slurry configuration area and then convey the mortar to a building point; the whole masonry can be built after the processes are repeated.

After each layer of masonry is built, the mortar joints of the whole layer of masonry are subjected to jointing treatment by personnel, so that mortar plumpness is guaranteed. And the surface of the masonry is cleaned, and after the cleaning work is finished, the brick type required by the next layer of masonry is conveyed. The masonry work of the whole coke oven needs to be repeated every day until the coke oven masonry is completed.

In conclusion, a large amount of manpower is needed for building the newly-built coke oven, the physical load of each worker is quite large, the repeated work per day is high, the requirement on the dimensional accuracy of the coke oven building is controlled in the millimeter level, and the requirement on the technical level of the building workers is also high.

In addition, the refractory bricks required by the coke oven can be more than 1000 types of brick types, and the shape and size errors are required to be within +/-3 mm. In the refractory production process, a cast iron grinding tool needs to be manufactured according to each brick type, and the green brick pressing process of the special-shaped brick is more complicated. And the damage of the corner is very common in the transportation process of the special-shaped brick, so that the integrity of the refractory brick is checked by personnel after the refractory brick is transported to a masonry site, and the refractory brick with serious damage can only be discarded. Therefore, the reduction of the firebrick shapes is also the key point for reducing the construction cost and improving the construction efficiency.

For the reasons, the invention aims at solving the problems in the coke oven masonry and developing an intelligent machine which is necessary for reducing the manpower requirement, reducing the number of refractory bricks and improving the coke oven masonry efficiency and quality.
