Rotating bucket disk type splitting device

Abstract

The invention provides a rotating bucket disk type splitting device. The rotating bucket disk type splitting device comprises a waste material chute (2), wherein a feeding hole (3) is formed in the top of a shell (1), the waste material chute (2) is connected to the lower end of the shell (1), a bucket disk (4) is arranged inside the shell (1), and takes the shape of a cone, the bottom of the bucket disk (4) is open, the top of the bucket disk (4) is fixedly connected with a rotating shaft, the rotating shaft extends out of the shell (1) and is connected with a transmission mechanism, the rotating shaft is arranged obliquely relatively to the vertical direction, at least two splitting openings (9) are formed in a conical surface of the bucket disk (4) at intervals, and sample collecting chutes (5) extending towards the exterior of the shell (1) are arranged at parts corresponding to the lower parts of the splitting openings (9) in the bucket disk. The rotating bucket disk type splitting device provided by the invention is large in adjustable range of splitting ratios, so that the sampling requirements of relatively large splitting ratios can be met. Meanwhile, the rotating bucket disk type splitting device is high in sample preparation efficiency, short in sample splitting time, and high in splitting precision.

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
