Embodiment

The utility model is described in detail below in conjunction with the accompanying drawings.

Embodiment 1：

Present embodiments provide for a kind of wet coal screen, and as illustrated in fig. 1 and 2, screen is by sieve chamber 103 and four groups of Screen assemblies Composition, four groups of Screen assemblies in sieve chamber 103 are parallel to each other and are generally aligned in the same plane, and every group of Screen assemblies are by a rotating shaft 105th, a set of bearing（Not shown in figure）If, a motor 106 and dry sieving disk 107 form, if dry sieving disk 107 with Rotating shaft 105 is that symmetrical centre axle is equidistantly fixed in rotating shaft 105, and one end of rotating shaft 105 and the side side wall of sieve chamber 103 rotate Connection, the other end are rotatablely connected through sieve chamber 103 by bearing and motor 106, each screening circle in two adjacent groups Screen assemblies It is arranged in a crossed manner between piece 107；The top for sieving chamber 103 sets feeding mouth 104, and the feeding mouth 104 is located at each group screening disk 107 Top, sieve the bottom of chamber 103, the lower section of each group screening disk 107 sets duff to export（Not shown in figure）, the bottom of sieve chamber 1, Rough coal is set to export 102 below one group of Screen assemblies at most edge.
