A rotary bucket pan type shrinker

Abstract

The invention provides a rotary bucket-type shrinking device, which includes a waste material chute (2), a material inlet (3) is provided on the top of the casing (1), and the waste material chute (2) is connected to the shell The lower end of the body (1), the inside of the housing (1) is provided with a bucket (4), the bucket (4) is conical, its bottom is open, the top of the bucket (4) is connected to the rotating shaft Fixedly connected, the rotating shaft extends to the outside of the casing (1) and is connected to the transmission mechanism, the rotating shaft is arranged in an inclined manner relative to the vertical direction, and the tapered surface of the bucket (4) is arranged at intervals There are at least two shrinkage openings (9), and a sample collection chute (5) extending to the outside of the casing (1) is provided in the bucket tray corresponding to the lower portion of the shrinkage openings (9). The reduction ratio of the present invention has a large adjustable range, and can meet the sampling requirements of a relatively large reduction ratio. At the same time, the sample preparation efficiency is high, the reduction time of samples is short, and the reduction precision is high.

Description

technical field [0001] The invention relates to a splitter, in particular to a rotary bucket-type splitter. Background technique [0002] In the design of mechanized sampling and preparation, the reducer is a device mainly used to complete the reduction of samples, and it is also the key equipment in the sample preparation system. [0003] Due to the miscellaneous quality of coal and the large variety of coal and serious inhomogeneity, it is very difficult to extract representative samples. Different occasions, needs, coal types, and batch coal quality inspections have strict regulations on the number, weight and distribution of sub-samples. This requires ensuring that the collected samples are representative. The sampling holes in the shrinker And the particle size of pulverized coal will affect the size of the reduction ratio, and the speed of the motor will also have a certain impact on the precision of the reduction. [0004] At present, the samplers used in the second...

Problems solved by technology

The rotary scraper type shrinker must use the belt to convey the material. Most of them realize the adjustment of the reduction ratio by the speed of the motor or the reducer. This adjustment method not only makes the change range of the reduction ratio smaller, but also cannot realize Sampling requirements for larger reduction ratios. In addition, this type of reduction device also has the matching problem of belt speed and scraper line speed.

The linear splitter is a first-generation product, which is generally used for primary sampling, and rarely used for secondary splitting, mainly because its linear structure and the handling of residual materials are very inconvenient for the site and design.

The existing secondary divider has a small adjustable range of division, low sample preparation efficiency, long time to divide the sample, and is easy to cause deviation
