Problems solved by technology

In the process of manual stirring, there are human factors such as the direction of rotation of the crucible, the angle of inclination and the stirring speed, and the coal sample is also easy to splash, which affects the mixing of the sample, resulting in inaccurate test results, and low test work efficiency and labor intensity. Big
[0004] The existing mechanical device can only achieve simple stirring, especially the lack of inclination angle, which cannot realize the comprehensive and sufficient stirring process required by the experiment, and fails to achieve the purpose of the experiment

Abstract

A stirring device for coal cohesion index measurement, comprising a base with a rotating shaft on the top, the rotating shaft is driven by an angle-driven motor, an angled inclined platform is provided on the rotating shaft, a crucible rotating sleeve containing a crucible is mounted on the angled inclined platform, and the crucible rotating sleeve is below A motor is provided, and there is a guide rod on one side of the angled inclined platform, and a crucible cover is sleeved on the guide rod. The top of the crucible cover is provided with a stirring motor and its gearbox, and the bottom is provided with a stirring rod driven by the stirring motor. The invention is simple in structure, reasonable in design, convenient to use, low in cost, easy to operate, and strong in practicability. The deficiencies in the prior art are overcome, and through actual use, the present invention greatly improves work efficiency, and the stirred samples can be successfully used for subsequent detection.

Description

technical field [0001] The invention relates to a stirring device for measuring caking index, in particular to a stirring device for testing coal caking index used in a laboratory. Background technique [0002] The caking index indicates the caking ability of the coal sample, and is a key index for judging the coking and coking properties of coking coal, and is also an important index for coal classification. The caking index test method is to mix a certain quality of test coal sample and special anthracite under specified conditions and heat it quickly to form coke. The obtained coke block is tested for strength with a drum, and its caking index is calculated. [0003] The stirring of the coal sample is an important step in the determination of the coal caking index in the laboratory. The sample is usually stirred manually or simply mechanically in a crucible. In the process of manual stirring, there are human factors such as the direction of rotation of the crucible, the ...
