Description

Technical Field

[0001] The utility model relates to the field of technical equipment related to coal washing and coal selection, in particular to a coal selection and dust removal device. Background Art

[0002] Raw coal is inevitably mixed with impurities during its generation, mining and transportation, and a large amount of coal dust is generated during production and transportation. In order to reduce the impurities and dust in raw coal and effectively and rationally utilize coal resources, it is necessary to separate coal into various products according to quality and specifications, and coal preparation machines are needed to screen the coal. However, during the use of ordinary coal preparation machines, due to the vibration of the coal preparation machines, the coal will move and rub against each other, which will continue to generate dust such as coal ash. Therefore, it is necessary to use dust removal devices to remove dust while selecting coal.

[0003] In existing dust removal operations, usually only exhaust fans are used to adsorb dust and coal ash. However, simple fan adsorption does not cover all aspects, and some dust and coal ash will still settle to the bottom of the coal preparation equipment due to gravity, making them difficult to remove.

[0004] Based on this, the utility model develops a coal preparation and dust removal device to solve the above-mentioned existing dilemma. Utility Model Content

[0008] The coal conveying device is movably arranged inside the frame structure of the dust removal device. A plurality of roller structures are arranged below the coal conveying device. The frame structure of the dust removal device can vibrate and slide above the roller structure by being pulled by a conveying motor.

[0009] Preferably, the central processor is electrically connected to the exhaust fan, the water pump, the transmission motor, the video monitoring device and the device control terminal respectively.

[0012] Preferably, hollow connecting pipe structures for connecting adjacent coal conveying devices are arranged on both sides of the bottom of the coal conveying device.

[0013] Preferably, the bottom and sides of the coal conveying device are both mesh hollow structures.

[0014] Preferably, the cross-sectional radius of the first and second drainage holes gradually decreases from top to bottom, presenting an inverted frustum-shaped structure.

[0015] Preferably, the cross-sectional radius of the exhaust tube structure 1 and the exhaust tube structure 2 gradually increases from top to bottom, forming a frustum-shaped structure.
