Abstract

The invention relates to a method and a device for rapidly manufacturing a pulverized coal polished section by ultrasonic defoaming, belonging to a method and a device for manufacturing pulverized coal polished sections. The device for manufacturing the pulverized coal polished section comprises an ultrasonic defoaming device and a polished section molding device, wherein an ultrasonic generator of the ultrasonic defoaming device is connected with a transducer by a lead; the transducer is connected onto a base by a heightening screw; the base is connected with a bottom seat; the upper end of the bottom seat is provided with an objective table; the polished section molding device is arranged on the objective table; a tool head is arranged above the objective table and is connected with the lower end of the transducer; the ultrasonic generator is provided with a display screen, frequency modulation rotary knobs and an inserting seat; two pistons of the polished section molding device can make free motion in a mould; the mould is in a cylinder shape; a push rod is arranged at one end of one piston, and one piston head is provided with a micro-pore. When the pulverized coal polished section is manufactured, bubbles of mixed liquid can be removed by the ultrasonic defoaming device, and the pulverized coal polished section is finally cleaned by ultrasonic waves. The pulverized coal polished section is manufactured by the mould, so that the waste of coal samples can be reduced, and short time and low cost are consumed.

Description

technical field [0001] The invention relates to a method and a device for making a pulverized coal light sheet, in particular to a method and a device for rapidly manufacturing a pulverized coal light sheet by ultrasonic defoaming. Background technique [0002] At present, evaluating coal quality, identifying mixed coal, and scientific coal blending are effective means of coal quality detection methods. By observing and manufacturing pulverized coal light slices, experiments such as the measurement of vitrinite reflectance, the quantitative determination of microscopic coal rock components, the measurement of coke optical structure and the determination of coke pore structure can be carried out, so as to judge the degree of metamorphism of coal and the best blending of coal. Index, vitrinite reflectance index has been used by more and more coking enterprises for coal trade and coal quality monitoring; the production quality of pulverized coal light film is one of the prerequ...
