Material taking hole opening and closing device, coal cake sampling measurement device and coal cake sampling measurement method

Abstract

The invention provides a material taking hole opening and closing device of side wall of tamping coal box, a coal cake sampling measurement device and a coal cake sampling measurement method. For the material taking hole opening and closing device, at least one material taking hole is formed in the outer side of at least one side wall of a tamping coal box; at least one opening and closing device is correspondingly arranged outside the material taking hole and is used for automatically opening and closing the material taking hole; each opening and closing device comprises a seal door and an opening device, wherein the seal door can be covered on the corresponding material taking hole in an openable way; the opening device is connected with the seal door; and the opening device is used for driving the seal door to be opened or covered on the corresponding material taking hole. The coal cake sampling measurement device comprises a material taking device, the material taking hole and a coal cake density measurement device, wherein the coal cake density measurement device can be used for calculating the density of a coal sample after the coal sample with a specified volume is taken out by the material taking device and is weighed.

Description

technical field [0001] The invention relates to coal cake density measuring equipment for a coking process, in particular to a feeding hole opening and closing device capable of automatically opening a feeding hole, a coal cake sampling and measuring device and a method. Background technique [0002] Figure 10 Shown is the structural schematic diagram of existing tamping coal box 3. Existing tamping coal box 3 comprises two side walls 31, a front wall (discharging briquettes), a rear wall (pushing briquettes) 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 ...

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
