Description

Visual closed coal riffle

Technical Field

The utility model relates to a coal check out test set technical field, more specifically says so and relates to a two dividers of visual closed coal.

Background

Coal division is an important work in a fuel sample preparation link in the thermal power industry, preparation of a full-moisture coal sample is a key link in coal division, and the representativeness of division is a very key problem; in order to ensure that the material sampling is representative, a material sample is divided equally by a divider. A commonly used riffle adopts an overhead hopper, a material distributing stop block is arranged in the middle below the hopper, and material samples falling from the hopper fall into two sides of the material distributing stop block randomly to realize material distribution. At present, the closed type riffle used commonly can reduce the moisture loss when preparing the full-moisture coal sample, is very helpful to the representativeness of the full-moisture sample, but the closed type riffle can't directly observe whether the coal flow is even in the division process, and the loading condition of the coal sample in the coal sample collection box, when the coal sample volume is great, the coal sample easily overflows the coal sample collection box or frequently takes out the coal sample collection box for avoiding the coal sample overflow to check, the actual operation is inconvenient

Therefore, it is an urgent need to solve the problem of the art to provide a visual closed type riffle which can find the volume of coal in a coal flow and a coal sample collection box in a dividing process in time.
