Embodiment Construction

[0018] Such as Figure 1 ~ Figure 3 The rear side shifting device with double movable walls of the coal trough shown is composed of a front baffle plate 1, a left side wall 2, a right side wall 3, a connecting hinge point seat 4, a lever 5, an oil cylinder 6, a fixed support 7, and a position stopper. Iron 8, tailgate 9, coal charging floor 10 and chain 11 etc. are made up of parts.

[0019] During the working process, the loose coal is first sent to the coal box 12 composed of the front baffle 1, the left side wall 2, the right side wall 3, the back baffle 9, and the coal loading floor 10, and the tamping on the top of the coal box 12 Hammer 14, loose coal is tamped into briquette 13. Then open the front baffle plate 1, the left side wall 2, the right side wall 3 drive the lever 5 to rotate through the oil cylinder 6 respectively, one end of the lever 5 is hinged with the fixed support 7, and the other end drives the connecting hinge point seat 4 and the left side wall 2, th...

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...
