Description
Technical field
The utility model belongs to the improvement of chain grate boiler coal feeder, particularly multi-functional even mixing layering coal supply apparatus.
Background technology
The flashboard coal-feeding mode that chain grate boiler is traditional and traditional a series of problem that decker brought, as: the raw coal that thickness does not wait mixes after the extruding of coal flashboard, be distributed on the traveling-grate stoker, cause the coal bed ventilation resistance big, make grate coal supply equipment ubiquity can not use the bigger coal of granularity, be not easy to maintenance, the problem that maintenance difficulty is big.
What traditional layering coal supply apparatus (the particularly above boiler of 20T) cann't be solved goes up the coal spontaneous whereabouts accumulation that the coal mode causes automatically because of uniting, (both sides lump coal is many to form piece end natural separation, concentrate in the middle of the duff) and cause the burning can not be synchronous, problem such as can not burn Wan.
Serial problems such as the bad control of coal-fired humidity, as: the coal yard humidification is subjected to temperature to influence the easy freezing in winter, coal is failed in influence, and adopt spray equipment humidification (generally adopting) is installed above conveyer belt in the defeated coal process, easily causes conveyer belt to skid and problems such as humidity is even inadequately.
The utility model content
The purpose of this utility model is to provide a kind of multi-functional even mixing layering coal supply apparatus, can make the coal that enters boiler grate reach coal-fired to do, humidity is even, rationally controlled humidity, layering is even, can improve the uniformity and the ventilation rate in coal seam, improve burning condition, improve efficiency of combustion.
The purpose of this utility model is achieved in that a kind of multi-functional even mixing layering coal supply apparatus, chain grate boiler is given coal bunker, the casing internal upper part of coal feeder is being provided with interior coal bunker, the suitable for reading connection of interior coal bunker given the coal bunker coal sliding tube, the lower openings of casing is connecting traveling-grate stoker, the humidification nozzle is being set above in interior coal bunker, below the humidification nozzle, setting gradually the agitating roller of symmetry and the coal moving roller that matches with interior coal bunker discharging opening from top to bottom, the coal supply roller that matches with interior coal bunker discharging opening is installed below interior coal bunker discharging opening, the sifter that matches with the coal supply roller is installed below the coal supply roller.
The utility model and main story chain grate boiler air-supply design principle (along fire grate length direction air zoning, along isobaric air supplying on the fire grate width) are complementary.
The course of work of the present utility model is: when coal gets off through coal sliding tube from coal bunker, after entering into coal feeder, earlier carry out reasonable humidification through the humidification nozzle, by the mechanism of agitating roller coal is carried out piece then, the end, do, humidity fully mixes, pass through the mechanism of coal moving roller and coal supply roller again, coal is pushed on the sifter, sifter is with coal layering in addition, thereby reach big down, go up the purpose of little layering step by step, make the coal seam loose, reduced flowing resistance, increased draught area and ventilation, and make coal seam uniformity on the whole fire grate, avoided occurring on the fire grate burner effectively, the phenomenon that burning such as black-tape is irregular; And the superiors' smalls realizes suspension combustion in running, improved grate calorific intensity and coal seam burnout velocity significantly, improved efficiency of combustion.
Therefore, the utility model can make the coal that enters boiler grate reach coal-fired and do, humidity is even, reasonable controlled humidity, and layering is even, has improved the uniformity and the ventilation rate in coal seam, improves burning condition, has improved efficiency of combustion.
Description of drawings
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is a sectional structure schematic diagram of the present utility model;
Fig. 2 is the utility model mechanical transmission structure schematic diagram.
The specific embodiment
A kind of multi-functional even mixing layering coal supply apparatus, as Fig. 1, shown in Figure 2, chain grate boiler is given coal bunker 1, casing 2 internal upper parts of coal feeder are being provided with interior coal bunker 3, the suitable for reading connection of interior coal bunker 3 given the coal bunker coal sliding tube, the lower openings of casing 2 is connecting traveling-grate stoker 9, above in interior coal bunker 3 humidification nozzle 4 is being set, below humidification nozzle 4, setting gradually the agitating roller 5 of symmetry and the coal moving roller 6 that matches with interior coal bunker 3 discharging openings from top to bottom, the coal supply roller 7 that matches with interior coal bunker 3 discharging openings is installed below interior coal bunker 3 discharging openings, the sifter 8 that matches with coal supply roller 7 is installed below coal supply roller 7.The agitating roller 5 of the sprocket wheel chain transmission symmetry of motor on reduction gearbox output shaft that install at the top outside casing 2 is stirring coaxial installation sprocket wheel chain drive coal supply roller 7 on the roll shaft, the sprocket wheel chain drive coal moving roller of installing on the coal supply roll shaft 6.On the pipeline that connects humidification nozzle 4, magnetic valve 10 is installed,, can regulates coal-fired humidity easily by the magnetic valve 10 control water yields, simple to operate.The structure of the agitating roller 5 of symmetry is two parallel helical feed rollers, and the hand of spiral of its helical blade is opposite, turns to identical.By the rotation of two parallel helical feed rollers 5, the hand of spiral of blade is opposite, makes coal back and forth movement vertically, reaches the effect that fully mixes, and the piece of coal, end are fully mixed, and humidity is even.The structure of coal moving roller 6 is the uniform moving tooth that is being provided with on the cylinder roll surface.By moving tooth uniform on coal moving roller 6 roll surfaces coal is transported on the coal supply roller 7 swimmingly, has solved the problem of sticking coal and canopy coal fully.The structure of coal supply roller 7 the fin shape of arranging vertically for radial equipartition on columniform roll surface and is dialled bar.The fin shape of uniform axially-aligned is dialled bar on coal supply roller 7 roll surfaces, drives fire coal when rotated, makes it evenly to fall on the sifter 8.Sifter 8 is made up of a plurality of vertical bar shape sieve castors, is adjusted to certain angle when normally using, and by the flow direction that changes coal breakage and the characteristics of motion of utilizing coal breakage, when making coal wander on the operating grate surface, forms big down, as to go up little hierarchal arrangement step by step form naturally.Motor is directly controlled coal-supplying amount by variable frequency adjustment speed by regulating the speed of service.
