Description

Technical Field

[0001] The invention relates to the technical field of test coke ovens, in particular to a hydraulic tamping device for test coke ovens. Background Art

[0002] In recent years, the extensive application of experimental coke ovens has provided a good way to determine an economically reasonable coking coal blending plan. The experimental coke oven has developed from the early bottom-loading structure to the side-loading structure that has been widely used in recent years. At the same time, the widespread application of ramming coking technology has greatly reduced the cost of coking, and also provided a good way to rationally utilize limited resources. Coking is processed by ramming, so for the experimental coke oven, it is also necessary to ram the material sample to increase the density. In the early stage of ramming, due to the loose material sample, when the hammer head falls for the first time, the air in the coal sample is quickly squeezed out, causing the material sample to splash around the hammer head, resulting in a lack of material sample in the center of the hammer head, and this phenomenon occurs every time the material is fed, resulting in uneven overall density of the material sample. Summary of the invention

[0003] The purpose of the present invention is to provide a hydraulic tamping device for testing coke ovens, which has the advantage of being easy to tampe evenly and solves the problem of uneven tamping in existing devices.
