Tamping equipment for experimental coke oven samples

Abstract

The invention relates to tamping equipment for the material sample of an experimental coking furnace. Sliding hammers are arranged at both sides of a tamping hammer and controlled by using steel wires and winding wheels; when the tamping equipment works, the winding wheels powerlessly control the sliding hammers, the tamping hammer falls freely, the sliding hammers are immobile on the relative position of the tamping hammer due to free falling body motion; when the tamping hammer is fallen to tamp coal, the sliding hammers are fallen due to an inertia effect to tamp the coal positioned at the peripheries of the tamping hammer; the bottom area of the tamping hammer is dispersed to the sliding hammers positioned at both sides by virtue of the structure, and air inside the coal can be fast discharged during tamping, so that the air is prevented from being not discharged due to large-area tamping, the potential energy consumed by high tamping air resistance caused because the air is difficult to compress is prevented, and the phenomenon that the air carried with the coal is splashed when the compressed air is discharged is prevented; when the sliding hammers are retracted after tamping, the steel wires firstly drive the sliding hammers to ascend and drive the tamping hammer to ascend together when ascending to the tail end of a second slide rail.

Description

technical field [0001] The invention relates to the field of coke oven coking processing equipment, in particular to a tamping equipment used for experimental coke oven material samples. Background technique [0002] The extensive application of experimental coke ovens in recent years provides a good way to determine an economical and reasonable coking coal blending scheme. At the same time, due to the extensive application of tamping coking technology, the cost of coking is greatly reduced, and it also provides a good way to rationally utilize limited resources. For mass production tamping coking, the tamping method is used, so for the experimental coke oven, the material sample also needs to be tamped to increase the density. However, the tamping of the experimental coke oven material samples has not been ideal all the time. The main reason is that the lack of understanding of this tamping process leads to insufficient attention. It is often believed that the amount of ma...

However, the longitudinal height of the material sample itself is much smaller than that of large-scale production, and its density distribution is extremely sensitive compared with large-scale production. The large fluctuation or unevenness of its density will directly lead to large differences in the final coking quality.

[0003] The existing tamping device uses a large-area pressing plate for tamping. Since there is air in the coal, and the gas is not suitable for compression, when the tamping hammer descends for tamping, the compressed air acts as a buffer to consume the potential energy. At the same time, when the gas escapes from around the tamping hammer, the compressed air will bring the coal splash
