Abstract

The invention discloses a moving dehydration device for underground water coal. The device comprises an arc grate screen, a hydraulic baffle, two layers of elastic rod screens, three layers of piano wire screens, a track, a grate screen bracket, a coal flow baffle, a chassis, wheels, a milling coal hole, an undersize hopper, an undersize water pipe, a screen frame and a vibration exciter, wherein the screen frame is fixed on the chassis; the chassis is provided with the wheels; the wheels are positioned on the track; the two layers of the elastic rod screens and the three layers of the piano wire screens are respectively arranged in the screen frame; the upper part of the two layers of the elastic rod screens is provided with the fixed arc grate screen; the arc grate screen is supported by the grate screen bracket; the grate screen bracket is fixedly connected on the chassis; the lower part of the screen frame is fixedly provided with the undersize hopper; the undersize hopper is connected with the undersize water pipe; the lower right part of the screen frame is fixedly provided with the milling coal hole; and the chassis on the upper right part of the milling coal hole is fixedly provided with the coal flow baffle. The moving dehydration device for the underground water coal has the characteristics of compact structure, lump coal impact resistance, good dehydration effect, stable and reliable working and the like.

Description

Technical field: [0001] The invention relates to a mobile dehydration device for underground water coal, which is suitable for processing underground water coal in coal mines, and is especially suitable for being installed at the head of the first belt conveyor for raw coal in the mine to dehydrate the water coal. Background technique: [0002] At present, underground coal mining often causes a large amount of water to enter the coal flow due to reasons such as water gushing at the working face. When the water content of the raw coal exceeds 20%, the coal-water mixture presents a viscous two-phase fluid, commonly known as water coal. . The emergence of water coal has brought a series of problems to follow-up operations such as transportation, lifting and storage, resulting in production accidents such as belt slippage, coal silting at the tail of the machine, and thin coal slime escaping into the warehouse, which greatly increased the labor intensity of employees and serious...
