Coal cake taking device and coal cake sampling and measuring device

Abstract

The invention provides a coal cake taking device and a coal cake sampling and measuring device. The coal cake taking device is installed on a main bracket on the outer side of one side wall of a tamping coal box, the material taking device comprises a main material taking frame, a material extractor, a main thrust device and a material pushing device; the main material taking frame is arranged on the main bracket in a sliding manner, and the main thrust device drives the main material taking frame to move forward or backward in a manner of being vertical to the side wall; the material extractor is fixedly installed on the end facing to the side wall of the main material taking frame and protrudes from the main material taking frame; the material extractor is propelled by the main thrust device to stretch into a material taking hole in the side wall to sleeve a coal sample; and the rear end of the material pushing device is fixed on the main material taking frame, the front end of the material pushing device stretches into the material extractor, and the front end of the material pushing device can be used for pushing out the coal sample obtained by the material extractor. The coal cake sampling and measuring device comprises a material taking device, a material taking hole and a coal cake density measuring device; and the coal cake density measuring device is used for calculating the density of the coal sample after weighing the coal sample with appointed volume taken out by the material taking device.

Description

technical field [0001] The invention relates to coal cake density measuring equipment for a coking process, in particular to a coal cake taking device and a coal cake sampling and measuring device capable of automatic material taking and measurement. 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 vertically ab...

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
