Description
Technical field
The utility model relates to a kind of screening distributor.
Background technology
The fuel of thermal power plant's circulating fluidized bed boiler is the gangue of certain proportion granularity, although come its particle size inequality in the coal in the colliery, it is not need the repetition fragmentation that most of material is arranged, and this part material generally accounts for 35～75% of whole material.If this a part of qualified particle diameter material sifts out without the screening apparatus for distributing and directly enters follow-up disintegrating apparatus, will cause the negative effect of following several respects to follow-up disintegrating machine.One, the long-time overload operation of disintegrating machine increases with electric energy consumption, and motor shortens service life; Two, cross the efficiency of combustion that crushing directly influences boiler greatly; Three, disintegrating machine inter deterioration aggravation, tup shortens service life greatly; Four, material is the current column and falls into disintegrating machine and fail even cloth and open, and steadily tup part eccentric wear is not serious can to cause the disintegrating machine operation, can't regulate the discharging particle diameter; Cause main motor of the stuck burning of tup and disintegrating machine to batter down when five, having big block ironware to enter disintegrating machine in the material.
At present, part has adopted screening plant and apparatus for distributing in the domestic thermal power plant coal handling system equipment, but its existing screening plant exists that material screening efficient is low, cloth is inhomogeneous, stop up sieve aperture, material fluidity that moisture is big is poor, blocking channel and contain problem such as ironware.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of efficient screening distribution device is provided, it is low to solve present screening distributor screening efficiency, the problems such as the excessive cloth that causes is inhomogeneous, chute blockage that wet because of material is sticking, and remove the ironware that contains in the material.
The purpose of this utility model is achieved through the following technical solutions: screening distributor, it comprises charging aperture, drapery panel, transmission device, filtration rope, tensioning apparatus, casing, motor and roller bearing, drapery panel is installed on the inwall of charging aperture below, the two ends of roller bearing all are equipped with transmission device and tensioning apparatus, connect by transmission device between the roller bearing, transmission device is connected with motor, filter on the tensioning apparatus that is installed in the roller bearing two ends of restricting and and strain, filter rope around roller bearing one week formation cylinder by tensioning apparatus.
Described screening distributor also comprises a deironing apparatus, and deironing apparatus is installed on the casing cover plate of cylinder compass screen surface top.
Described screening distributor also comprises an observation panel, and observation panel is installed on the side panel of casing.
Described screening distributor also comprises a big particle diameter material outlet and a qualified particle diameter material outlet, and big particle diameter material outlet is positioned at the outside of terminal cylinder compass screen surface, and qualified particle diameter material outlet is positioned at the below of cylinder compass screen surface.
Spacing between the described cylinder is 10～15mm.
Described deironing apparatus is a permanent-magnetic iron expeller.
Described tensioning apparatus is perhaps added a loose flange by a mounting flange and is formed by a mounting flange, filters rope one end and is fixed on the mounting flange, and the other end is fixed on the loose flange, and loose flange is connected with the mounting flange of homonymy by screw.
