Abstract
The steel ball self-grinding method for hot-state furnace slag treatment is characterized by that the surface of the fixed body where the steel ball and furnace slag are impacted in the rotary drum can be made into the inward recessed type, in the inward recessed type space is filled up with steel ball and furnace slag, the most inner layer steel ball and furnace slag contacted with inward recessed surface of the fixed body are being in relative static state. Said invention can change the two-side plane baffle-plates of the fixed body into inward recessed type, so that it can protect the fixed body against the wear and tear due to diect impact of steel ball and furnace slag.
Description
Technical field
The present invention relates to thermal state cinder processing unit, relate in particular to drum process slag treatment device.
Background technology
Chinese patent application number 01105800.5 discloses a kind of " double-cavity steel slag treating drum mechanism ".This treating apparatus comprises two squirrel-cage cylinders partially filled steel ball, that opening is settled relatively with same axis in the chamber, and the retainer ring of a fixed in position is arranged between the opening of two cylinders, and the shunting disk of a rotation is housed at the retainer ring inner chamber.Fixing radially fan shape baffle is arranged between retainer ring two ends and shunting disk, and retainer ring, fan shape baffle and front and rear baffle have been formed fixed body.Slag falls from shunting disk and enters in the cylinder, continuous rotation along with cylinder, the steel ball and the slag that are contained in the rotary drum ceaselessly roll, overturn, steel ball and slag particle constantly carry out relative motion along certain track under the condition of high temperature, and constantly impact, the fan shape baffle of grinding fixed body, referring to Fig. 2.Fixed body will be directly in the face of the steel ball that scorches and rotating of 1000 ℃ of left and right sides slags and the direct impact and the grinding of slag charge, the situation of temperature distortion and wearing and tearing is very serious, though set up cooling and reinforcement measure, be enhanced service life, but with respect to quantity-produced iron and steel enterprise, service life that it is of short duration and frequent replacing, maintenance have all brought very big inconvenience to production, and production cost is higher relatively.
Summary of the invention
The present invention has overcome fixed body defective easy to wear in the existing drum process slag treatment device, provide a kind of thermal slag to handle with steel ball autogenous grinding method and fixed body device, this steel ball autogenous grinding method is that two side shields with fixed body change inner concave shape into by the plane, make fixed body avoid slag and the direct impact wear of steel ball, avoid fatigue at high temperature, increase the service life, raise labour productivity.
The present invention is achieved in that a kind of thermal slag processing steel ball autogenous grinding method, it is characterized in that the steel ball in the swing roller is become inner concave shape with the fixed body Surface Machining that slag impacts, the inner concave shape space has been full of steel ball and slag, is in relative static state with the innermost layer steel ball and the slag of the contact of fixed body concave surface.
A kind of thermal slag is handled and is used the fixed body device, comprises retainer ring, fan shape baffle and front and rear baffle, it is characterized in that fan shape baffle is an inside recess, and the degree of depth of inside recess is the diameter of at least one steel ball.
Above-mentioned thermal slag is handled and used fixed body device, described inside recess is that left-right symmetry distributes, and inside recess is the V-type cell, and there is space conduct cinder notch down the centre of two V-type cells.
Above-mentioned thermal slag is handled and is used the fixed body device, and described inside recess bottom has down cinder hole.
Operation principle of the present invention is that the steel ball and the moving slag particle that are rolling constantly impacted, the fixed body both sides baffle surface of grinding is shunk back to inside recess with being rotated originally, make steel ball and slag particle in inside recess, not move or move seldom, be in relative static conditions.Just very little to the impact and the wearing and tearing of the concave surface of fixed body like this, thus the fixed body surface protected.
The present invention compared with prior art, fixed body both sides inner concave shape surface abrasion is little, the long service life of fixed body, labor productivity height.

Among the figure: 1 steel ball, 2 slag particles, 3 fixed bodies, 4 rotary bodies, 5 static relatively steel balls, 6 liner plates, 7 gussets, 8 shunting disks, 9 inside recesses (V-type cell, fan shape baffle), 10 cooling bodies, 11 cylinders, 12 side plates, 13 fixing ring flat-plates, 14 gussets
The specific embodiment
Provide embodiments of the invention below in conjunction with accompanying drawing
Referring to Fig. 1, Fig. 2, a kind of thermal slag is handled with steel ball autogenous grinding method, be that the steel ball 1 in the swing roller 4 is become inner concave shape with fixed body 3 Surface Machining that slag 2 impacts, the inner concave shape space has been full of steel ball 5 and slag 2, the degree of depth of inner concave shape has one deck steel ball 1 at least, steel ball 1 and slag 2 that the cylinder 4 that rotates so outside drives are ceaselessly carrying out relative motion along certain track, but be in relative static state with the innermost layer steel ball 5 and the slag 2 of the contact of fixed body 3 concave surfaces, tangible sound interface promptly occurs.Reduce the wearing and tearing of fixed body 3 at the interface by the autogenous grinding of steel ball 1, and then playing the purpose of protection fixed body 3.
Use the fixed body device referring to a kind of thermal slag processing of Fig. 3, Fig. 4, comprise retainer ring, fan shape baffle and front and rear baffle.The retainer ring of semicircle shape is positioned at the bottom of shunting disk 8, and form by the frame shape structure of a plurality of inside recesses 9, wherein fixedly ring flat-plate 13 is the motherboards that constitute whole retainer ring, for increasing the fixedly intensity and the stiffness of ring flat-plate 13, is welded with an amount of gusset 7 and 14 in the fixing bottom of ring flat-plate 13.Fixedly the both sides of ring flat-plate 13 are fan shape baffle 9, fan shape baffle 9 is an inside recess, the degree of depth of inside recess 9 is the diameter of at least one steel ball, inside recess 9 distributes for left-right symmetry, inside recess 9 is the V-type cell, and the arc surface of V-type cell 9 upper surfaces and shunting disk 8 balances each other, and leaves suitable slit between the two, the size in this slit runs well can guarantee shunting disk 8, can stop again that bigger irregular cold bloom 10 enters to be as the criterion; Inside recess 9 bottoms promptly fixedly have down cinder hole on the ring flat-plate 13.There is the space centre of two V-type cells 9 as following cinder notch, following cinder notch to open cinder hole corresponding with the following cinder hole opening on the fixing ring flat-plate 13, be convenient in time clean out the residues that be with on shunting disk 8 surfaces; Part cooling body 10 and slag charge can " be fixed " in the inside of V-type cell 9, this part cooling body that is " fixed " 10 and slag charge are with respect to V-type cell 9 transfixions, have only the part cooling body 10 of outer surface to participate in the motion of cooling bodies 10 in the cylinders 11 and exchange mutually, can guarantee like this V-type cell 9 and fixedly ring flat-plate 13 avoid the wearing and tearing of moving cooling body 10 and slag charge.Liner plate 6 and side plate 12 are easily to grind part, are convenient to change.
