Coke oven tamping machine for tests and uniform density control method thereof

Abstract

The invention relates to the field of coke oven tamping machines and in particular relates to a coke oven tamping machine for tests and a uniform density control method thereof. The height difference of a sample before and after tamping is detected in real time through a controller, the lifting height or tamping time of a tamping hammer is regulated, and the uniformity of the tamped sample is guaranteed. The method comprises the following steps of: (1) inputting a preset target density value rho in the controller; (2) performing pre-tamping during the first tamping; and (3) automatically tamping through a tamping mechanism under control of the controller until the height H of the detected sample and a target height value are consistent, and stopping tamping. Compared with the prior art, the method has the beneficial effects that the uniformity of the sample density can be effectively improved, so that an accurate and reliable result is obtained in a coking test on the stable, scientific and strict basis, and the influence of human factors of operators on the test result is alleviated to be minimum; the equipment is higher in degree of automation, the labor intensity of the operators is reduced, and the personal potential safety hazard is eliminated.

Description

technical field [0001] The invention relates to the field of coke oven tamping machines, in particular to a test coke oven tamping machine and a method for controlling the uniform density thereof. Background technique [0002] The extensive application of experimental coke ovens in recent years has provided 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 test coke oven, the material sample also needs to be tamped to increase the density. However, the tamping of the test 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 mate...

Problems solved by technology

[0006] In addition, the current test tamping machine is generally heavy in structure, and the operation is labor-intensive. The operator needs to touch the material sample, and there are safety hazards to personal injury in the mechanical structure.
