Description
Technical field
The utility model belongs to the supporting coal-feeding device of fluid bed furnace, is specially the coal-fired classifying screen of fluid bed furnace.
Background technology
Coal-fired fluidized bed stove use procedure needs coal supply, and coal-fired particle diameter generally need to reach certain requirement can use (standard is φ < 16mm), and the former coal particle of particle diameter >=16mm need to could be used after fragmentation.In industry, have the mode that adopts reciprocating sieve sorting, exist floor space large, efficiency is low, power consumption is high, cannot realize the shortcoming that the coal-fired serialization of fluid bed furnace is used, and bring serious airborne dust.For overcoming the above problems, realize that raw coal screening is efficient, low energy consumption, minimizing operation place airborne dust, it is imperative in clean environment firendly mode, to sieve.
Summary of the invention
The utility model, for above weak point, provides a kind of fluid bed furnace coal-fired classifying screen, and the fire coal screening of using for fluid bed heat wind furnace is conducive to be mingled with the coal-fired mechanization sorting fragmentation in bulk footpath, improves efficiency of combustion.
The utility model solves the technical scheme that its technical problem adopts: the coal-fired classifying screen of a kind of fluid bed furnace, include shell, screen cloth, rotating shaft, motor and reductor, described shell sidepiece is provided with charging aperture, described enclosure is provided with screen cloth, described screen cloth connects screen cloth support, described screen cloth support is fixed on rotating shaft, described rotating shaft terminal is arranged on the sidewall of shell, described rotating shaft connects motor and reductor, described motor and reductor are fixed on shell sidepiece by support, described outer casing underpart is provided with fine grained blanking cone bucket and coarse fodder blanking hole.
Further, described screen cloth outside is also provided with circular arc closed protective cover.
Further, described screen cloth is set to bore barrel-shaped, and the both sides of the edge line of described screen cloth becomes 5-8 ° of angle with rotation, and described screen cloth adopts high-abrasive material stainless steel wire to make, and the mesh on screen cloth evenly arranges.
Further, described charging aperture and rotating shaft are 40 ° of-60 ° of angles.
Screen cloth of the present utility model is punched-plate or woven screen, is designed to 5 ° of-8 ° of angles cones barrel-shaped, is conducive to improve bulky grain or lump material and screens and be pooled to coarse fodder mouth;
In screen cloth outer setting circular arc closed protective cover, avoid airborne dust diffusion, there is depositing dust noise reduction function;
The utility model apparatus structure is compact, makes simply, and separative efficiency is high, effective;
The utility model is finally realized the instructions for use of coal-fired particle diameter φ < 16mm, finally for hot-blast stove provides qualified burning coal.
Accompanying drawing explanation
It shown in Fig. 1, is structural representation of the present utility model;
It shown in Fig. 2, is side view of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:
As shown be a specific embodiment of the present utility model, the coal-fired classifying screen of a kind of fluid bed furnace, include shell 1, screen cloth 2, rotating shaft 3, motor and reductor 4, described shell 1 sidepiece is provided with charging aperture 5, described shell 1 inside is provided with screen cloth 2, described screen cloth 2 connects screen cloth support, described screen cloth support is fixed on rotating shaft 3, described rotating shaft 3 two ends are arranged on the sidewall of shell 1, described rotating shaft 3 connects motor and reductor 4, described motor and reductor 4 are fixed on shell 1 sidepiece by support, described shell 1 bottom is provided with fine grained blanking cone bucket 6 and coarse fodder blanking hole 7.
Described screen cloth 2 outsides are also provided with circular arc closed protective cover.
Described screen cloth 2 is set to bore barrel-shaped, and the both sides of the edge line of described screen cloth becomes 5-8 ° of angle with rotating shaft 3 lines, and described screen cloth 2 adopts high-abrasive material stainless steel wire to make.
Described charging aperture 5 is 40-60 degree angle with rotating shaft 3.
While using the utility model, raw coal is packed in shell of the present utility model from charging aperture 5, starter motor and reductor 4, driven rotary axle 3 rotates, rotating shaft 3 drives screen cloth 2 rotations by screen cloth support, the raw coal entering is under centrifugal force and Action of Gravity Field, the raw coal coarse granule of diameter >=16mm moves to feed opening one side from charging aperture, the raw coal filtering out enters broken process by coarse fodder blanking hole 7 and carries out fragmentation, diameter < 16mm fine grained raw coal connects lifting conveying equipment by fine grained blanking cone bucket 6 simultaneously, be mixed into Combustion of Hot Air Furnace with raw coal and fine grained raw coal after fragmentation.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned giving an example, and the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
