Description

Cold slag slagging machine

The utility model is a kind of cold slag slagging machine, belongs to the removing or the treatment facility of a kind of combustion products or combustion residue.

CFBB and fluidized bed furnace all are to be the boiler of fuel with the low heat value, therefore the lime-ash that produces is also many especially, and the temperature of lime-ash is higher, generally about 900 degree, directly abandonment not only makes working environment comparatively abominable as rubbish with it, also can waste wherein contained heat energy, the method for therefore directly warm sludge being delivered to lime-ash factory site or direct water pouring warm sludge is also inadvisable.The scientific research personnel has invented cold slag slagging machine for this reason.Existing cold slag slagging machine has spiral water-cooled, air-cooled, double layer sleeve barrel spiral rolling water-cooled and drum-type several.Wherein spiral water-cooled cold slag slagging machine mechanical wear is serious, and power consumption is big; Air-cooled cold slag slagging machine inhomogeneous cooling is even, also the fine particle of lime-ash may be blown into burner hearth once more; Double layer sleeve barrel spiral rolling water-cooled cold slag slagging machine film-cooled heat is little, need sleeve longer, and floor space is bigger, and blade wear is serious, and difficulty is installed; The drum-type cold slag slagging machine adopts the cold slag tube ash-slag delivery of a plurality of six ribs, has increased film-cooled heat, and the structure but its each cold slag tube is fixed as one will integral replacing after cold slag tube damages, thereby use cost is higher, processing and difficulty is installed also.

The purpose of this utility model is: design that a kind of film-cooled heat is big, deslagging is effective, cold slag tube is easy to the cold slag slagging machine processing, install and change.

The utility model comprises its support and rack-mount by the urceolus of driven by motor and the cold slag tube in the urceolus, outer tube inner chamber is separated into by front and rear baffle joins grit chamber, cooling chamber and slag trapping chamber, cold slag tube is positioned at cooling chamber, be separately installed with out on the front and rear baffle, water inlet pipe, on the front/rear end that go out, water inlet pipe and its outer axle sleeve passes urceolus and the support, bearing be connected, its at least one end of at least two cylindric cold slag tubes that inner surface has guide plate has outer bead, and screw passes outer bead and is connected with baffle plate.

The utility model has changed the mounting means of cold slag tube, integrated form it is former and baffle plate changes separate form into, and fix by screw, thereby after cold slag tube damages for ease of maintenaince and change, and make the utlity model has and be easy to the advantage of processing and installing.And the utility model has adopted cylindric, has also installed guide plate in it additional, makes the utility model also have the deslagging good effectiveness.

Bead outside the utility model can be shaped at an end of cold slag tube is equipped with filler between its other end and the baffle plate, makes its installation more simple.

For ease of discharging the gas that enters in the cooling chamber, urceolus tilts to place, and its outlet pipe is higher than water inlet pipe, at the highest point of cooling chamber the blast pipe of both ends open is installed, and blast pipe is between the outer rim and hose nozzle of urceolus.When urceolus rotates, the air accumulation in the cooling chamber in the top, when blast pipe was positioned at the extreme higher position, gas entered blast pipe, and arrived the outlet pipe place along blast pipe, and was discharged by outlet pipe.The gas of discharging in the cooling chamber helps guaranteeing cooling effect.

Guide plate on the slag inside pipe wall of the present utility model can be made by the spiral metal plate, also can be made of square tube or pipe, and at this moment the two ends of its square tube or pipe are communicated with inlet tube and outlet tube, and at this moment the film-cooled heat of lime-ash is bigger, and cooling effect is better.

Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
