Description
(1) technical field
The present invention relates to be used for the boiler auxiliary equipment technical field in biomass fuel power plant, be specially a kind of modified water-cooling spiral tapping machine.
(2) background technology
The fuel that the biomass fuel power plant uses is discarded object such as straw, straw, cornstalk, branch bar and the bark etc. of agricultural, production of forestry, contains trace elements such as a certain amount of potassium in these fuel lime-ash, can be used as also field of fertilizer.Biomass fuel contains a certain amount of alkali metal usually, easily produces slagging scorification after the boiler internal combustion, and the slag fragmentation of adopting water-cooling spiral tapping machine that boiler is discharged in the industry usually is cooled to below 80 ℃ again and carries, and is used for also field.If take traditional hydraulic slag discharging mode, then the fertilizer component in the lime-ash is soluble in water, has not only increased the treating capacity of sewage, and lime-ash is difficult to utilize again; And the cold spiral tapping machine of sleeping that uses in the market, its cooling water flows in helical blade and helical axis, and it does not contact with lime-ash, can guarantee the utilization again of lime-ash, but cooling effect is not ideal enough.
(3) summary of the invention
At the problems referred to above, the invention provides a kind of modified water-cooling spiral tapping machine, it is guaranteeing that heat exchange area is big, tapping temperature is low, good cooling results under the condition that lime-ash can utilize again.
Its technical scheme is such: it comprises motor, described motor connects power transmission shaft, be set with helical blade on the described power transmission shaft, described helical axis is installed on U type tube body, described cylindrical shell is provided with the lime-ash entrance and exit, described power transmission shaft and described blade are provided with the cooling-water duct that is connected, and the entrance and exit of described cooling-water duct is arranged at the transmission the tip of the axis respectively, it is characterized in that: be provided with cooling-water duct in the described barrel wall.
In the said structure of the present invention, be provided with cooling-water duct in the cylindrical shell, can increase film-cooled heat greatly like this, under the effect of blade and power transmission shaft cooling, lime-ash can cool off fast, guarantees lower tapping temperature like this.
(4) description of drawings
Fig. 1 is front view of the present invention and partial sectional view;
Fig. 2 is a left view of the present invention among 1 figure.
(5) specific embodiment
See Fig. 1, Fig. 2, the present invention includes motor 9, motor 9 connects power transmission shaft 3, be set with helical blade 4 on the power transmission shaft 3, power transmission shaft 3 is installed on U type tube body 10, and cylindrical shell 10 is provided with lime-ash inlet 1 and outlet 5, power transmission shaft 3 and blade 4 are provided with the cooling-water duct that is connected, the inlet 7 of cooling-water duct and outlet 8 are arranged at the end of power transmission shaft 3 respectively, and what be provided with cooling- water duct 11,2 in cylindrical shell 10 walls and be cylindrical shell is the inlet opening of cylindrical shell except that water hole, 6.
