Abstract
The utility model relates to an agitator with double layer vanes for the ash disposal system of a steam power station. The utility model can effectively solve the problems in the prior art of big ash water ratio, big volume, easy dusting and sedimentation, the ash water ratio is raised to one to three from one to fifteen, the means of arranging two cylinder bodies which can be communicated with each other on the upper and lower parts in the agitator is taken by the utility model, each cylinder body is provided with a layer of stirring vanes, an activation cone is arranged on the top part of a main shaft to make the dry ash drop from an ash inlet and evenly be scattered in the cylinder, and a special water spraying facility which can spray water in different directions is arranged on the top of the activation cone. The speed adjustable transmission mode of combining a chain wheel and a speed reducer for a direct coupled electric machine is used by the utility model.
Description
The utility model relates to the agitating device that a kind of power plant ash disposal system is used, and can be widely used in the stirring and remote conveying of thermal power plant flyash.
The flyash in thermal power plant enters the collection ash bucket after treatment, enters mixer by ash bucket again, adds a large amount of water and stirs, and the mortar after will stirring evenly is then discharged by grout outlet, delivers to Hui Gouzhong and goes.The mixing plant of present domestic employing all adopts single cylinder, individual layer blade construction, and cement-water ratio generally about 1:15, expend a large amount of water, and pulp concentration instability, produces deposition in the machine, and mixer needs periodic cleaning.Motor is adopted in its driving section, is unfavorable for that the denseness of looking mortar regulates rotating speed.Grout outlet originally is located at the bottom, makes that partly flyash does not just directly drop to the conveying that the bottom grout outlet has influenced mortar through stirring as yet, so effect is not ideal.For a long time, the electric power research personnel carried out the examination of repaying of each side, but improvement effect is still not obvious.
The purpose of this utility model is that a kind of improved twi-tier blade mixer will be provided, it can solve the excessive contradiction of cement-water ratio effectively, make cement-water ratio bring up to 1:3 by the 1:15 in past, and can solve phenomenons such as in mixer, producing precipitation, making mortar stably be transported to Hui Gouzhong goes, moreover be that can to solve mixer bulky, the problem of maintenance inconvenience.
The purpose of this utility model is achieved in that upper and lower two cylindrical shells that are connected is set in mixer, one deck stirring vane is arranged in each cylindrical shell.Blade in the upper shell adopts fan-shaped, and the blade in the lower shell adopts arc surfaced.The coaxial rotation of upper and lower two-layer blade.Be that the main shaft top is provided with an activation awl near the ash inlet place in the mixer ash bucket, the activation awl is during with the blade synchronization rotation, and the dry ash that ash inlet was fallen is dispersed in the tube equably, the speed in the time of can keeping dry ash to fall again.Water injector above the activation awl adopts the stainless steel tube that is drilled with several ten different directions apertures to be looped around the ash bucket inwall, can spray water to different directions, has both guaranteed the uniformity of water spray, has guaranteed the continuity of current again.The kind of drive that the transmission device of mixer adopts sprocket wheel to combine with reductor.Its grout outlet is arranged on the side of lower shell.
The utility model makes the interior buck of cylindrical shell through twice stirring because adopted the double shell twi-tier blade, and mortar mixes and stirs even especially, makes cement-water ratio bring up to 1:3 from about 1:15, and this can save the water rate number every year and pick up ten thousand yuan for a power plant.In addition, cause the minimizing of buck discharge capacity, this has significant meaning for reducing environmental pollution.Moreover, dwindled the volume of mixer, easy access.The grout outlet of mixer is arranged on the side of bottom cylindrical shell, and the one, flyash is unlikely to resemble and directly drops to grout outlet the prior art and discharge without stirring, and the 2nd, can increase the discharge pressure of grout outlet.The kind of drive that this machine has adopted sprocket wheel to combine with reductor can be looked the denseness of mortar and speed governing at any time, makes security of operation, stable, reliable, service life of prolonging complete machine.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Describe in detail according to concrete device and the operational detail that the utility model proposes below in conjunction with Fig. 1, Fig. 2, Fig. 3.
This mixer comprises two simplified (11) and (10) that are connected up and down, on the top of cylindrical shell (11) ash bucket (1) is arranged.Cylindrical shell central vertical direction is main shaft (4), activation awl (2) is installed on the top of main shaft (4), blade (5), blade (6), sprocket wheel (7) down are installed successively, above the activation awl, there is a water injector (3) to be looped around the ash bucket inwall, this device is made with stainless steel tube, is drilled with the aperture of several ten different directions on the steel pipe.Sprocket wheel (7) links to each other with direct-coupled electrical machinery reductor (9) with chain.Mixer and reductor all are installed on the base (8).During work, rotate because direct-coupled electrical machinery reductor (9) drives sprocket wheel (7), thereby main shaft (4) and activation awl (2), blade (5), (6) are rotated synchronously, this moment, flyash entered ash bucket (1) by ash inlet, fell on the activation awl (2).Rotation because of activation awl is dispersed in the tube dry ash equably, and simultaneously, water injects water injector (3) from water inlet, evenly spray water to different directions from several ten apertures, and according to the inflow of how much regulating of ash quantity fed, to reach the purpose of control cement-water ratio.Buck obtains mixing and stirring for the first time in cylindrical shell (11), falls into then to carry out the stirring second time in the cylindrical shell (10), extrudes grout outlet at last, is output outside the factory.Accompanying drawing (2), (3) are respectively the vertical view of blade (5), (6), and (12) are axle sleeve among the figure, and (13) are gusset, and (14) are profiled sleeve.
Claims (5)
1, the twi-tier blade mixer that is used for the thermal power plant ash disposal system, this machine has an ash bucket and cylindrical shell, on the main shaft of cylindrical shell central authorities blade is housed, it is characterized in that cylindrical shell (11) and cylindrical shell (10) two cylindrical shells for being connected up and down, blade (5) in the upper shell adopts fan-shaped, and the blade (6) in the lower shell adopts arc surfaced.
2, twi-tier blade mixer according to claim 1 is characterized in that in ash bucket near the ash inlet place being that the main shaft top is provided with an activation awl (2), activation awl and blade synchronization rotation.
