Device ensuring rear side movement of double movable walls of coal chute

Abstract

The invention discloses a device ensuring rear side movement of double movable walls of a coal chute, which is used in the process of coking by adopting tamping. The device comprises a baseplate and a chain, wherein the baseplate is positioned on the chain and forms a coal box with a front baffle, a left side wall, a right side wall and a rear baffle which are positioned on the baseplate; tamping hammers are arranged above the coal box; and a coking chamber of a coke oven is arranged in front of the coal box. The device is characterized in that the left side wall and the right side wall are respectively provided with cylinders; the cylinders are hinged with the middle parts of levers by cylinder rods; one end of the levers is hinged with fixed supports and the other end thereof is hinged with connecting hinge point bases; the hinge points are positioned on position stops; the position stops are respectively connected with the left side wall and the right side wall fixedly; and the movement ends of the levers are freely connected with the position stops by circular arcs and ensure the left side wall and the right side wall slip toward the rear side when being separated with coal cakes.

Description

technical field

[0001] The invention relates to a charging device for a coke oven, which is used in the coking process of the coke oven. Background technique

[0002] In the 1980s, most of my country's coking industry adopted the top-loading coke oven coking process. With the continuous development of coking technology, the coking process of top-charging coke ovens shows its shortcomings day by day. In the 1990s, modern tamping and coking technology has become more and more popular. Using the tamping process for coking, tamping loose coal into briquettes for smelting, can not only mix a certain amount of low-quality coal instead of high-quality coal, so that the utilization of coal resources and carbon resources is more reasonable, but also under the same coal blending conditions, Improve the quality of coke.

[0003] During the coking process of tamping process, it is necessary to put loose coal into the coal box and tamp it into briquettes through a tamping machine, and...
