Abstract

The invention relates to the field of coke oven tamping machines, in particular to a coke oven tamping machine for testing and a method for controlling the average density thereof. The controller detects the height difference between the material sample before and after tamping in real time, and adjusts the tamping hammer. The specific operation is as follows: 1) Input the preset density target value ρ in the controller; 2) Pre-tamping should be performed at the first tamping; 3) Tamping The solid mechanism automatically tamps under the control of the controller until the height H of the detected material sample is consistent with the height target value, and the tamping ends. Compared with the prior art, the beneficial effects of the present invention are: 1) It can effectively improve the uniformity of the sample density, so that the coking test can obtain accurate and reliable results on a stable, scientific and rigorous basis, and at the same time, the operator's artificial The influence of factors on the test results is minimized; 2) The equipment has a higher degree of automation, which reduces the labor intensity of the operator and eliminates personal safety hazards.

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 an average density control method thereof. Background technique [0002] The extensive application of test coke ovens in recent years provides a good way to determine economical and reasonable coking coal blending schemes. Test coke ovens have developed from the early bottom-mounted structure to the side-mounted structure that has been widely used in recent years. At the same time, due to the wide application of tamping coking technology, the cost of coking has been greatly reduced, and it also provides a good way for the rational use of limited resources. Large-scale production tamping coking adopts tamping method, so for the test coke oven, it is also necessary to tamp the material sample to increase the density. However, the tamping of test coke oven material samples has not been ideal for a long time. The main reason is that the ...
