Abstract

The application discloses a rotary chute type division device, which comprises a chute component in which a coal flow is flowed, a driving control device, and a slotting discharging hopper; the driving control device is connected with the chute component and used for driving and controlling the chute component to perform rotary movement, and the slotting discharging hopper is located at the tail end of the chute component and used for cutting the coal flow from the chute component; the slotting discharging hopper is provided with a discharging hopper with different sampling angles. For the uniform coal flow passes through the upper part of the slotting discharging hopper by exact time ratio, several parts of coal samples with different masses and fixed quality are acquired from the slotting discharging hopper; the rotary chute type division device is good for improving the division precision. The application further discloses a coal sampling preparation device; for the coal sample canbe acquired at fixed quality, the rotary chute type division device is good for improving the preparation efficiency of the coal sample.

Description

technical field

[0001] The invention relates to the field of coal sample preparation, in particular to a rotary slide tube type shrinker. The invention also relates to a coal sample preparation device. Background technique

[0002] As an important strategic energy source, coal is widely used in power generation, heating, chemical industry and so on. However, since the composition of coal varies widely from region to region, in order to be able to accurately control the amount of coal used and where it is used, it is usually necessary to conduct further composition inspections on the mined coal. Naturally, coal sample preparation equipment is inseparable from the inspection process . Generally, coal sample preparation equipment includes crushers, shrinkers, mixers, screening equipment, drying equipment, etc., to prepare collected coal samples into coal samples for analysis that can represent the characteristics of the original coal samples. Therefore, coal sample preparati...
