Sampling and sample preparation system for cross-double rail train

Abstract

The invention discloses a sampling and sample preparation system for a cross-double rail train. The system is characterized by comprising lifting devices sampling trolley buses, sampling motors, an operating room, electromotors, a transverse support frame, vertical support frames, crushers, a PLC controller and dividers, the middle portion of the transverse support frame is provided with the operating room, the two ends of the transverse frame are slidably provided with the sampling trolley buses, the crushers are arranged on the lower portion of the sampling trolley buses, the dividers are arranged on the lower portion of the crushers, and sample collectors are arranged on the lower portion of the dividers; when sampling is carried out on the double-rail train, the sampling requirements of a large quantity of raw materials are met, the processes of sampling and sample preparation are performed separately for centralized management, the sampling speed is quick, the arrangement of a roller press and drying device can meet different requirements of sample preparation, the practicability is improved, when a sampling machine samples, the relative speed between a sampling machine and atrain carriage is zero, and no relative displacement occurs to cause the damage of the sampling machine; the servo performance is strong, and the protection function is strong.

Description

technical field [0001] The invention relates to the technical field of material sampling, in particular to a sampling and sample preparation system across a double-track train. Background technique [0002] In many large factories such as thermal power plants and ore processing, a large amount of materials are transported in every day, and the materials mainly refer to coal or ore. In order to understand the composition of the incoming materials, it is necessary to take certain material samples for the materials on each material delivery vehicle according to the relevant standards. In the sampling of materials, most of them are still manually sampled, but manual sampling is labor-intensive. , the efficiency is low, especially for materials loaded in layers, manual sampling is limited, and the collected samples are not representative, and the sampling vehicle can only take samples from monorail trains. For sampling across double-track trains, its working efficiency is still ...

In order to understand the composition of the incoming materials, it is necessary to take certain material samples for the materials on each material delivery vehicle according to the relevant standards. In the sampling of materials, most of them are still manually sampled, but manual sampling is labor-intensive. , the efficiency is low, especially for layered loading materials, manual sampling is limited, and the collected samples are not representative, and the sampling car can only take samples from monorail trains. For sampling across double-track trains, its working efficiency is still It is relatively low and cannot meet the sampling and sample preparation requirements of a large number of raw materials. In the prior art, the train sampling and sample preparation processes are carried out separately, which is not convenient for centralized operation and management, and the degree of mechanization is not high.
