Automatic sampling system with Z-type conveying devices

Abstract

The invention discloses an automatic sampling system with Z-type conveying devices. The automatic sampling system comprises two or more sampling processing units and the one or more Z-type conveying devices. Each Z-type conveying device comprises a lower horizontal conveying channel, a lifting conveying channel, and an upper horizontal conveying channel, wherein the lower horizontal conveying channel, the lifting conveying channel, and the upper horizontal conveying channel are sequentially connected to form a Z-type conveying channel. Each lower horizontal conveying channel is communicated with the output end of the corresponding sampling processing unit for the previous level, each upper horizontal conveying channel is communicated with the input end of the corresponding sampling processing unit for the next level, and the material conveyed from each lower horizontal conveying channel is upwards conveyed to the corresponding upper horizontal conveying channel through the corresponding lifting conveying channel and is output to complete the material conveyance. According to the automatic sampling system, the Z-type conveying devices are adopted to achieve flexible conveyance of material or samples in each unit (device), labor intensity is greatly lowered, working efficiency is extremely improved, the occupied area of the whole sampling system is very small, and the space use rate is high.

Description

technical field [0001] The invention relates to the field of coal sample preparation equipment, in particular to an automatic sample preparation system with a Z-shaped conveying device. Background technique [0002] For coal quality analysis, it is actually a process of sampling analysis. Coal is an inhomogeneous substance (particle size, distribution of quality characteristics, etc.), and the sampled parent stock is generally relatively large (ranging from tens of tons to tens of thousands of tons), and the samples that can represent the quality and characteristics of the entire stock sample are drawn to the maximum extent. The process of sampling representative samples is called "sampling". At present, there are many methods such as mechanical sampling, manual sampling, and semi-mechanical sampling. Each country has mandatory standards, and sampling work must be carried out in accordance with the standards. [0003] After the sample is collected according to the stan...

Problems solved by technology

[0006] (1) The manual method is used to prepare samples step by step, and the materials are manually transferred from the upper sample preparation unit (equipment) to the next level sample preparation unit (equipment). Manual intervention in the link is prone to fraud

[0007] (2) The traditional belt conveyor is used, but this method cannot be lifted vertically, in order to transfer the material from the lower output port of the upper sample preparation unit (equipment) to the upper input port of the next sample preparation unit (equipment) , it is necessary to lengthen the length of the conveyor belt to reduce the lifting slope, and this will inevitably make the entire sample preparation system occupy a large area and the space utilization rate is not high

[0008] (3) The traditional belt conveying method still faces several problems: the operation of the belt conveying method is not stable enough, causing the material (sample) to run away, which ultimately affects the accuracy and effectiveness of sample preparation; the belt conveying method is easy to raise dust, which affects the life of equipment and office The environment and the health of the operator; the belt conveying method cannot be self-cleaning, and material (sample) residues and sample contamination are prone to occur, which will eventually affect the accuracy and effectiveness of sample preparation
