Description
Technical field
The utility model relates to a kind of quantitative stalk feed hopper that is used for to the coal-powder boiler weight feed stalk fuel of electricity generation system.
Background technology
At present, stalk fuel has been used as the fuel of grate furnace in the electricity generation system, and grate furnace is lower to the big or small length requirement of stalk fuel, and stalk fuel joins in the grate furnace just passable by artificial or mechanical system, feed way labour intensity is big like this, and is time-consuming.Stalk fuel also is not used as the fuel of coal-powder boiler, because coal-powder boiler is a suspension combustion, requires fuel particle little, and burning velocity is fast, and the tail-off time is short, and coal dust feed hopper shape is up big and down small, by the machine supplying powder feed.Stalk fuel will be used for coal-powder boiler, then need stalk as far as possible little, and stalk is low weight, and is mobile poor, can not directly supply with stalk fuel with the coal dust feed hopper.
Summary of the invention
The purpose of this utility model provides a kind of quantitative stalk feed hopper that is used for to the coal-powder boiler weight feed stalk fuel of electricity generation system.
For achieving the above object, the utility model is taked following design:
A kind of quantitative stalk feed hopper is characterized in that it comprises: cyclone separator, sack cleaner, high-speed centrifugal fan, feed bin, screw unloading device, have the material gas blender of feed valve;
Cyclone separator has charging aperture, gas outlet and discharging opening;
Feed bin forms truncated cone-shaped outward, and the top of feed bin evenly is provided with three level indicators;
Be provided with the first rotation discharge valve between the discharging opening of cyclone separator and the feed bin;
Sack cleaner has import, exhaust outlet and blanking port; The import of sack cleaner is connected with the gas outlet of cyclone separator, is provided with the second rotation discharge valve between the blanking port of sack cleaner and the feed bin;
High-speed centrifugal fan is connected with the exhaust outlet of sack cleaner;
The screw unloading device is made up of 12 horizontal conveying worms and two longitudinal spiral conveyers, article 12, horizontal conveying worm is located at the bottom of feed bin inner chamber, article two, the longitudinal spiral conveyer is located at the bottom of feed bin, the axis of the axis of longitudinal spiral conveyer and horizontal conveying worm is perpendicular, and the longitudinal spiral conveyer is connected with the outlet of horizontal conveying worm;
Material gas blender is connected with the outlet of longitudinal spiral conveyer.
The feed bin bottom evenly is provided with most the nozzles that are used for loose metal.
Sack cleaner is a gas tank formula pulsed jet cloth filter.
The utility model has the advantages that:
The utility model is owing to adopt above design, charging aperture with cyclone separator during installation is connected with hammer-mill, spent material is with carrying air to enter cyclone separator, most of material is delivered to feed bin by the first rotation discharge valve, and carry air velocity to reduce, and carry the tiny material of part and enter sack cleaner, material separates in sack cleaner once more with carrying air, the clean air of allow compliance with emission standards enters atmosphere by centrifugal blower, and material is delivered to feed bin by the second rotation discharge valve.
High-speed centrifugal fan is positioned at material-transporting system backmost, so induction system is negative pressure transportation, has that sealing structure is good, characteristics of working site cleaning, blower fan long service life.Material to cyclone separator, again to sack cleaner, realizes that the pipeline of stalk material is carried from hammer-mill.
Three level indicators on feed bin top, if wherein the high point of two level indicators indication just can be considered the bin-level height, if wherein two level indicator indication low spots just to can be considered bin-level low.When bin-level is high, stop the conveying that the upstream stalk prepares line, then accelerate stalk when bin-level is low and prepare the line feeding speed, to realize the effect of quantitative feed.
Article 12, horizontal conveying worm adopts frequency control, and the range of speeds 0～40rpm can intersect two longitudinal spiral conveyers feeding outside the storehouse when starting horizontal conveying worm.The longitudinal spiral conveyer also passes through the feed valve feed with mass transport to blender.For preventing solid accumulation, laterally conveying worm can rotating (both can be left-handed, but dextrorotation again), and auger conveyor is turned right during operate as normal, turns left generally manually or use during maintenance.Laterally conveying worm is that stalk fuel with feed bin inside continuously is transported in the longitudinal spiral at the outside two ends of feed bin.Rotating speed by changing horizontal conveying worm and the increase and decrease platform that puts into operation can change the mass transport amount, changes the air-transport system material-gas ratio.
The quantitative stalk feed hopper of the utility model is because the feed bin bottom evenly is provided with most the nozzles that are used for loose metal.When the stalk material in the feed bin exists hinge joint or affixed phenomenon, can feed high pressure air and carry out loose metal.
