The combined type boiler slag exactor comprises a shell body, a feed hopper and a water-cooling shaft. The feed hopper is installed at one end of the shell body, a slag hole is formed at the other end of the shell body, a water-cooling clamp sleeve is sleeved on the outer side of the bottom of the shell body, the water-cooling shaft is connected with a drive device and penetrates through the shell body, and screw blades are installed on the periphery of the water-cooling shaft. The combined type boiler slag exactor is characterized in that breaking knives are arranged on the lower portion, located in an opening of the feed hopper, of the water-cooling shaft, a wind blocking door is arranged on space between the slag hole and the tail end of the water-cooling screw blades, and on the inner side of the upper wall of the shell body, and a rotating shaft of the wind blocking door is perpendicular to the water-cooling shaft in the axial direction.
Description
Technical field
The utility model relates to the boiler slag removal field, is specially a kind of 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 namely 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 to cool off it, so that conveying and the transhipment of safety; Because therefore fuel can be formed bulk when the stove internal combustion clinker needs clinker broken before cooling; If the slag-drip opening of boiler directly is communicated with atmosphere, high-temperature gas will spray in stove, or cold air bleeds in the stove, will cause security incident, therefore need to flapper be installed at the slag-drip opening place and prevent gas leakage.Conventional slag-draining device generally is comprised of slag breaker, cold slag machine and flapper.The flapper device combination carries out yet adopt conventional slag breaker---cold slag machine---, and tapping process needs multiaxis to drive, and equipment investment is large, energy consumption is high, take up room large, operation control is complicated.
The utility model content
---cold slag machine---flapper device combination existence investment is large for conventional slag breaker, energy consumption is high, take up room large, complicated shortcoming is controlled in operation, the utility model provides a kind of composite boiler mucking machine, and its equipment cost is low, energy consumption is low, it is little to take up room, equipment operation control is simple.
A kind of composite boiler mucking machine, it comprises housing, feed hopper and water-cooling shaft, described feed hopper is installed on an end of described housing, the described housing other end has slag notch, the outside of described housing bottom is set with water-cooling jacket, described water-cooling shaft connecting drive device also passes described housing, and helical blade is installed around the described water-cooling shaft; It is characterized in that: described water-cooling shaft, the below that is positioned at the outlet of described feed hopper are provided with crushing cutter; Neutral place between described water-cooling shaft helical blade end and described slag notch, described housing upper wall inboard is provided with wind blocking door, and the rotating shaft of described wind blocking door is axially vertical with described water-cooling shaft.
It is further characterized in that:
Between crushing cutter, described water-cooling shaft top is provided with grid, described grid interlude is semicircle, it is wrapped in the upper semicircumference part of described water-cooling shaft, the extension, both sides of the semi-circular portion of described grid is planar portions, and described planar portions has covered the neutral between water-cooling shaft and the described housing.
It further is characterised in that:
Described water-cooling shaft, be provided with one section its axial length of crushing cutter greater than described slag inlet length;
Described crushing cutter is the paddle formula with angle of inclination, and described crushing cutter is inboard, hold in the same way the band tooth with the water-cooling shaft rotation direction;
Every grid lattice correspondence 1～3 is crushing cutter in the described grid.
After adopting equipment of the present utility model, by being provided with crushing cutter and grid at water-cooling shaft, below being positioned at slag inlet, reach the purpose of pulverizing lime-ash; Pulverize section and be slightly larger than the slag inlet width, guarantee that lime-ash all enters the pulverizing section and pulverizes; Crushing cutter is the paddle formula with angle of inclination, has on the one hand the effect of broken lime-ash, has on the other hand the effect of carrying through broken lime-ash; Water-cooling shaft loads without helical blade near one section of slag notch, and the material slag is piled up in this section, and the wind blocking door acting in conjunction, reaches the effect of sealing, and its action function is identical with flapper; The parts that the utility model equipment adopts all are conventional components, price is lower, overall cost is significantly less than conventional slag breaker---cold slag machine---flapper device combination, and drive the overall process of finishing simultaneously fragmentation, cooling, Anti-air-leakage and short distance conveying by single shaft, the flapper device combination will reduce the conventional slag breaker---cold slag machine---of its energy consumption greatly, pulverize section and seal section and be positioned at enclosure interior, its space size is significantly smaller than conventional slag breaker---cold slag machine---flapper device combination, and the many effects of an axle are so that control simpler.
