Embodiment Construction

[0021] For ease of understanding, the sample preparation shrinker described in the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] This embodiment provides a kind of sample preparation reducer, such as Figure 1-Figure 3 As shown, the sample preparation shrinking device includes a distributor 1, a shrinking funnel 2 and a sample retainer 3 from top to bottom;

[0023] The distributor 1 comprises a distributor body 101 whose outer peripheral surface is a conical surface. The outer peripheral surface of the distributor body 101 is provided with several diversion passages 103, and each diversion passage 103 is inclined from top to bottom, and the direction of inclination is the same; 101 empty sleeve on an upright fixed shaft 4, the fixed shaft 4 is fixedly connected with the shrinking funnel 2, and the fixed shaft 4 and the shrinking funnel 2 are coaxial;

[0024] The shrinking funnel 2 is an inverted c...

Abstract

The invention discloses a sample preparation reducer, relates to the technical field of coal sample preparation, and can solve the technical problem of low operating reliability of the reducer. The sample shrinking and dividing device includes a distributor, a shrinking funnel, and a sample retainer from top to bottom; the distributor includes a distributor body whose outer peripheral surface is a conical surface. The diversion channel is arranged obliquely from top to bottom, and the direction of inclination is the same; the distributor body is emptied on an upright fixed shaft, and the fixed shaft is fixedly connected with the shrinking funnel, and the fixed shaft and the shrinking funnel are coaxial; The shrinking funnel is an inverted conical structure, and the side wall of the shrinking funnel is provided with a blanking hole. The sample preparation divider is used to divide the sample.

Description

technical field [0001] The invention relates to the technical field of coal sample preparation, in particular to a sample preparation reducer. Background technique [0002] In the process of coal sample preparation, shrinkage is a key step. The reduction is to reduce the amount of coal sample under the condition that the particle size of the coal sample remains unchanged, so as to reduce the follow-up workload and achieve the required amount of coal sample for inspection. Usually, the coal sample is divided by using a sample preparation divider. [0003] The above-mentioned shrinking and dividing device for sample preparation includes a distributor, a shrinking and dividing funnel, a sample retainer, a driving motor and a transmission mechanism, etc., wherein the shrinking and dividing funnel is provided with a blanking hole. When the sample reducing and dividing device divides the coal sample, the drive motor drives the transmission mechanism to run, and the transmission ...
