Coal cake density measuring device and coal cake sampling and measuring device

Abstract

The invention provides a coal cake density measuring device and a coal cake sampling and measuring device. The coal cake density measuring device is installed on a main bracket on the outer side of the side wall of a tamping coal box, the measuring device is installed on a main bracket below a material taking hole in the side wall, and the measuring device comprises a coal bucket and an automatic weighing device below the coal bucket; and the density of a coal sample can be directly calculated after the weighing device automatically weighs the coal sample with appointed volume. The coal cake sampling and measuring device comprises material taking devices, material taking holes and the coal cake density measuring device; the three material taking devices are arranged on the outer side of one side wall of the tamping coal box, and the three material taking devices are respectively located on the upper corner, the centre and the lower corner of the side wall; and the three material taking holes are formed at the outer side of the side wall in a manner of being corresponding to the material taking devices of the coal cake taking device, the three coal cake density measuring devices are respectively installed below the material taking holes, and the density of the coal sample can be directly calculated after the coal cake density measuring devices automatically weighs the coal sample with appointed volume.

Description

technical field [0001] The invention relates to coal cake density measuring equipment for a coking process, in particular to a coal cake density measuring device capable of automatic weighing and measurement and a coal cake sampling and measuring device. Background technique [0002] Figure 10 Shown is the structural schematic diagram of existing tamping coal box 3. The existing tamping coal box 3 includes two side walls 31 , a front wall, a rear wall and a plurality of main supports 32 . Coal can be loaded between these two vertically placed side walls 31 for forming coal cake M, and the outer surfaces of the two side walls 31 are respectively equipped with a plurality of main supports 32 arranged at equal intervals, so that the two vertical The side wall 31 placed is fixed in the outer frame of the coal transportation platform, and the main bracket 32 ​​here is a part of the lateral fixing frame of the side wall 31 . The main support 32 is a plurality of beams verticall...

AI Technical Summary

Problems solved by technology

[0005] 1. The measurement of the existing briquette density is all done manually. At the same time, the feeding point is located on the top of the briquette, and the coal material on the top of the briquette is the remaining coal after the tamping briquette is formed. The tamping density is not high. There is a large gap between the measurement result and the actual briquette density

[0006] 2. After taking the material, it is necessary to manually bring the coal material to the car for weighing. The weighing cycle is long, and the density of the coal cake cannot be monitored in real time, and the collapse of the coal cake cannot be prevented in time.

[0007] 3. Since the entire operation process was manual in the past, human factors have a great influence on the measurement results, the accuracy of the measurement density is not high, and the stability is poor due to the influence of personal operation level
