Background technology
Since the eighties in last century, many units Foreign Experience, transform original radial mode mill separator as axial meal separator, separator height and volume increase greatly, and the more original radial mode separator of the air-flow stroke in separator is more reasonable, isolation resistance reduces, owing to adding the shock centrifugation of axial baffle, separating effect also obviously improves, and achieves good techno-economic effect, but overall operation stability is very poor, need often to safeguard; Later stage, through improving, eliminates inner cone and returns powder, and changes the shock of inner cone bottom cone into back taper, and cyclone performance makes moderate progress, but its capacity utilization obviously reduces, and pulverized coal fineness is also poor, and all there is serious concentrated wear problem.
Summary of the invention
The present invention proposes the two baffle plate mill separator of a kind of series connection axial type, it is rational in infrastructure, function admirable, improve pulverized coal fineness, be conducive to the burning of pulverized coal particle in stove and burn, can improve the economy of pulverized coal preparation system and boiler controller system operation, economic benefit is obvious, has important application value.
Technical scheme of the present invention is:
The two baffle plate mill separator of a kind of series connection axial type, comprises an Outer Taper, is provided with inner cone in described Outer Taper, and the bottom of described inner cone is fixedly connected with a shock cone; The top of described Outer Taper offers two symmetrically arranged outlets, and bottom is a powder-returning funnel; Form a circular passage between described Outer Taper and inner cone, bottom-uply in this passage be respectively equipped with first gear board component and second baffle assembly.
Preferably, described first gear board component and second baffle assembly are all formed as ring-type; Described first gear board component and second baffle assembly form by one or more baffle plate.
Preferably, independent of one another between described baffle plate and baffle plate, the rotating shaft that baffle plate is individually fixed in Outer Taper inner surface and inner cone surface by two ends is fixed, and described baffle plate can overturn around described rotating shaft.
Preferably, four installation feet are provided with around described Outer Taper outer surface of upper.
Preferably, the internal diameter of described outlet is bottom-up gradually little setting.
Preferably, two pieces of gripper shoes are also provided with between described first gear board component and second baffle assembly; The two ends of described gripper shoe are fixedly connected with inner cone surface and Outer Taper inner surface respectively.
Preferably, described shock cone is overall is taper, and its lower surface is a plane.
The invention provides the two baffle plate mill separator of a kind of series connection axial type, beneficial effect is: the resistance reducing separator, improves Gravity Separation effect; Improve the capacity utilization of separator, reduce metal consumption and occupied space thereof; Alleviate the concentrated wear of original axial meal separator, extend the service life of equipment; Inner without any accumulated powder dead angle, thoroughly stop interior cone blocking powder.
