Coal separation device based on wet coal or frozen coal

Abstract

The invention discloses a coal separation device based on wet coal or frozen coal. The device comprises a coal feeding bin; the bottom of the coal feeding bin is connected with a shell; and a conveying belt or a grate is arranged at the bottom of the shell. The device is characterized in that the shell is provided with a wet coal stirring roller in the lower side position of the coal feeding bin; stirring cutters are uniformly arranged on the wet coal stirring roller; a coal shifting rotating roller is arranged below the wet coal stirring roller; an inclined screening module is arranged at the bottom of the shell; a coal poking rotating roller is arranged between the coal shifting rotating roller and the screening module; the bottom of the screening module is connected with a net plate; the net plate is connected with an outlet of the shell; and the conveying belt or the grate is positioned below the screening module and the net plate. Preferably, the hole aperture of the net plate is larger than the hole aperture of the screening module. The coal separation device pretreats the wet coal or the frozen coal, can conveniently convey the wet coal or the frozen coal to boilers, and guarantees normal heating.

Description

technical field [0001] The invention relates to a coal separation device based on wet coal or frozen coal. Background technique [0002] At present, there are still some open-air industrial boiler rooms in our country. When it rains, snows or the climate is humid, the coal fired will become wet coal or frozen coal, which often leads to coal blocking, poor coal loading or bonding and screening Problems such as components seriously affect normal heating, so wet coal or frozen coal must be pretreated before entering the boiler. Contents of the invention [0003] In view of the above problems, the present invention provides a coal separation device based on wet coal or frozen coal, which performs pretreatment on wet coal or frozen coal, facilitates the transportation of wet coal or frozen coal to boilers, and ensures normal heating. [0004] In order to achieve the above-mentioned technical purpose and achieve the above-mentioned technical effect, the present invention is rea...
