Abstract
The invention relates to the field of boiler deslagging, and particularly relates to a combined type boiler slag extractor with low equipment cost, low energy consumption, small occupied space, and simple operation and control of equipment. The combined type boiler slag extractor comprises a shell, a feed hopper and a water cooling shaft; the feed hopper is installed at one end of the shell, and the other end of the shell is provided with a slag outlet; a water cooling jacket is sleeved outside the bottom part of the shell, the water cooling shaft is connected with a driving device and passes through the shell, and spiral blades are installed at the surrounding of the water cooling shaft. The combined type boiler slag extractor is characterized in that a breaking cutter is arranged below the water cooling shaft at the outlet of the feed hopper; a windshield door is arranged inside the upper wall of the shell at a neutral position is located between the tail end of the spiral blade of the water cooling shaft and the slag outlet; and a rotating shaft of the windshield door is axially perpendicular to the water cooling shaft.
Description
Technical field
The present invention relates to the boiler slag removal field, be specially the composite boiler mucking machine.
Background technology
Boiler ash has value, for the ease of the follow-up comprehensive utilization of lime-ash, usually adopts dry cinder discharging (cooling of promptly directly not spraying water directly is not discharged in the water yet).But lime-ash is in the condition of high temperature when burner hearth is discharged, and therefore need cool off it, so that the conveying and the transhipment of safety; Because therefore fuel can be formed bulk when the stove internal combustion clinker needs clinker broken before cooling; The slag-drip opening of boiler is if directly be communicated with atmosphere, and high-temperature gas will spray in stove, or cold air bleeds in the stove, will cause security incident, therefore need flapper be installed at the slag-drip opening place and prevent gas leakage.Conventional slag-draining device generally is made up of slag breaker, cold slag machine and flapper.Yet adopt conventional slag breaker---cold slag machine---flapper equipment combination to carry out, tapping process needs multiaxis to drive, and equipment investment is big, energy consumption is high, take up room big, operation control is complicated.
Summary of the invention
---cold slag machine---flapper equipment combination existence investment is big to conventional slag breaker, energy consumption is high, take up room big, complicated shortcoming is controlled in operation; The invention provides the composite boiler mucking machine, its equipment cost is low, energy consumption is low, it is little to take up room, equipment operation control is simple.
The composite boiler mucking machine; It comprises housing, feed hopper and water-cooled axle; Said feed hopper is installed on an end of said housing, and the said housing other end has slag notch, and the outside of said housing bottom is set with water-cooling jacket; Said water-cooled axle connects drive unit and passes said housing, and helical blade is installed around the said water-cooled axle; It is characterized in that: said water-cooled axle, the below that is positioned at the outlet of said feed hopper are provided with broken cutter; Neutral place between said water-cooled axle helical blade end and said slag notch, said housing upper wall inboard is provided with wind blocking door, and the rotating shaft of said wind blocking door is axially vertical with said water-cooled axle.
It is further characterized in that:
Between broken cutter; Said water-cooled axle top is provided with grid; Said grid interlude is semicircle; It is wrapped in the upper semicircumference part of said water-cooled axle, and the extension, both sides of the semi-circular portion of said grid is a planar portions, and said planar portions has covered the neutral between water-cooled axle and the said housing.
It further is characterised in that:
Said water-cooled axle, be provided with one section its axial length of broken cutter greater than said slag inlet length;
Said broken cutter is the paddle formula with angle of inclination, and said broken cutter is inboard, hold the band tooth in the same way with the water-cooled rotational axis direction;
Every grid lattice corresponding 1～3 are broken cutter in the said grid.
After adopting equipment of the present invention,, reach the purpose of pulverizing lime-ash through being provided with broken cutter and grid at the water-cooled axle, below being positioned at slag inlet; Pulverize section and be slightly larger than the slag inlet width, guarantee that lime-ash all gets into the pulverizing section and pulverizes; Broken cutter is the paddle formula with angle of inclination, has the effect of broken lime-ash on the one hand, has the effect of carrying through broken lime-ash on the other hand; The water-cooled axle loads near one section no helical blade of slag notch, and the material slag is piled up and the wind blocking door acting in conjunction in this section, reaches the effect of sealing, and its action function is identical with flapper; The parts that present device adopted all are conventional components; Price is lower; Overall cost is significantly less than conventional slag breaker---cold slag machine---flapper equipment combination; And drive through single shaft and to accomplish broken, cooling, anti-leaking out and overall process that short distance is carried simultaneously, conventional slag breaker---cold slag machine---the flapper equipment combination of its energy consumption will reduce greatly, pulverizes section and seal section and is positioned at enclosure interior; Its space size is significantly smaller than conventional slag breaker---cold slag machine---flapper equipment combination, and effect more than make control simpler.
