Description
Technical field
The utility model belongs in all kinds of body of heater use procedures, for stoping the flue gas producing in stove to discharge outside stove, is carried out centralized recovery, and is easy to realize the unlimited and closed of fire door.
Background technology
Zinc (Zn) is important parent metal, is widely used in metallurgy, galvanizing and casting zinc processing and other fields, and the production of 0# zinc, zinc-containing alloy product mainly adopts electrolysis cathode zinc metal sheet as zinc raw material.The production of conventional galvanizing alloy generally adopts frequency cored induction furnace fusing negative electrode zinc metal sheet to obtain 0# zinc zinc liquid, zinc liquid is guided to alloyage in line frequency coreless induction furnace by chute again, when by zinc metal sheet fusing and zinc liquid water conservancy diversion, alloying ingredient process, top layer zinc liquid is exposed in air completely, under hot conditions, oxidation generates zinc oxide, conventional galvanizing alloy is 99.995% to zinc grade requirement, the generation of zinc oxide not only affects the chemical composition of product, and can cause the physical imperfections such as alloy pig slag inclusion, internal shrinkage in casting cycle.Therefore, in order to improve zinc direct yield and the quality of guaranteeing conventional galvanizing alloy product, need before aluminium alloy casting, drop into ammonium chloride and carry out slag making, slagging process can produce a large amount of flue gases, and the line frequency coreless induction furnace in actual production process is also undertaken the task of anti-molten alloy casting slag simultaneously, in return slag process, also can produce a large amount of flue gases, in flue gas, not only contain the valuable metals such as zinc, also contain the compositions such as sulphur, nitrogen, carbon, directly discharge can cause environmental pollution, causes a large amount of metal losses simultaneously.Yet because line frequency coreless induction furnace design adopts cylindrical closed bell, its permission is highly 200mm, and 10 tons of stove diameters are 1500mm, for meeting whole boiler face slag making, slag hitting and anti-slag demand, need in process of production bell to open wide, cause the completely outer row of flue gas who produces.In addition, the cylindrical bell 180kg that weighs, prize to realize mobile rotation by manpower, causes operating difficulties.Of the present utility model coming into operation, has thoroughly solved the problems referred to above.
Summary of the invention
The object of this device is achieved by the following technical solution.
The bell that gathers dust, the utility model feature is: comprise lifting rotation mechanism and taper bell; Wherein: lifting rotation mechanism is vertically fixed on support by top chock, step by screw mandrel two ends, in screw mandrel bottom, be arranged with screw rodb base, on screw mandrel, be positioned at and on lower bearing, be also arranged with a rotating seat, be provided with a duplex needle bearing edge and be enclosed within on screw mandrel, on lower bearing, be also connected with a guide plate; On screw mandrel top, be positioned at and on support, be connected with handwheel; On rotating seat, being fixed with arm is connected with taper bell.
The utility model working method is, by rotation hand wheel, screw mandrel is moved up and down, thereby drive the bell being connected with screw mandrel by arm partly to move up and down, when screw mandrel is moved downward to screw rodb base, screw mandrel is fixed, now bell just with airtight connection of fire door of line frequency coreless induction furnace, can not left rotation and right rotation, when screw mandrel moves up disengaging screw rodb base, screw mandrel can move left and right, and drives the bell disengaging fire door that partly moves up, and bell can move left and right with screw mandrel simultaneously.By rotating handwheel, realized moving up and down and left rotation and right rotation of bell, can reach easily the switch of bell and the object that position is adjusted.When handwheel is clockwise during rotation hand wheel, screw mandrel departs from screw rodb base and moves up, and can move left and right around rotating seat simultaneously, and when counter clockwise direction rotation hand wheel, screw mandrel moves down, during to screw rodb base in impaction state, can not left rotation and right rotation.
Bell part is connected ，Sui lifting rotation mechanism and moves up and down with lifting rotation mechanism by arm, be designed with charging aperture, slag hitting mouth and outer air duct mouth, can guarantee that bell sentences at any time closed condition and don't affect normal production operation and dust collection effect.
Bell partial design has taper dust collection cover, charging aperture, slag hitting mouth and outer air duct mouth, the materials such as zinc liquid import in stove by charging aperture, slag making, slag hitting operation and intermediate alloy drop into, cast alloys slag is anti-molten etc. is undertaken by slag hitting mouth, in whole operation process, the outer air duct mouth of bell is closely connected with dust arrester all the time, in stove, under the effect of taper bell inner wall pressure and dust arrester draft, at airduct mouth place, produce pressure differential, flue gas focuses on the outer air duct mouth of taper bell along taper bell inwall, is more fully absorbed by dust arrester.
The utlity model has following advantage:
1, the flue gas producing in stove is absorbed by dust arrester installation after can concentrating by taper bell, controlled the outer row of flue gas, reduce environmental pollution, the flue gas that dust arrester absorbs is simultaneously processed rear centralized recovery by sedimentation, valuable metal in flue dust is able to effective recycling, has created considerable economic benefit.
2, the lifting rotation mechanism adopting has realized rotation, the movement of bell easily, has reduced employee's operation labor intensity, has saved the activity duration.
3, in operation process, bell, in closed condition, has solved fire door and has opened wide the potential safety hazard that operation exists.
4, this apparatus structure is simple, cheap, easy to operate, is installed on fire door top, takes up room little.
Below in conjunction with the drawings and specific embodiments, the utility model is further explained.
Accompanying drawing explanation
Accompanying drawing 1 is front view of the present utility model.
In figure: screw mandrel (1) top chock (2) step (3) support (4) screw rodb base (5) rotating seat (6) needle bearing (7) guide plate (8) handwheel (9) arm (10) taper bell (11).
The specific embodiment
See Fig. 1, a kind of packaged type bell that gathers dust, the utility model feature is: comprise lifting rotation mechanism and taper bell; Wherein: lifting rotation mechanism is vertically fixed on support 4 by top chock 2, step 3 by screw mandrel 1 two ends, in screw mandrel 1 bottom, be arranged with screw rodb base 5, on screw mandrel 1, be positioned at and on lower bearing 1, be also arranged with a rotating seat 6, be provided with duplex needle bearing 7 edges and be enclosed within on screw mandrel 1, on lower bearing 1, be also connected with a guide plate 8; On screw mandrel 1 top, be positioned at and on support 4, be connected with handwheel 9; On rotating seat 6, being fixed with arm 10 is connected with taper bell 11.
The utility model working method is, by rotation hand wheel, screw mandrel is moved up and down, thereby drive the bell being connected with screw mandrel by arm partly to move up and down, when screw mandrel is moved downward to screw rodb base, screw mandrel is fixed, now bell just with airtight connection of fire door of line frequency coreless induction furnace, can not left rotation and right rotation, when screw mandrel moves up disengaging screw rodb base, screw mandrel can move left and right, and drives the bell disengaging fire door that partly moves up, and bell can move left and right with screw mandrel simultaneously.By rotating handwheel, realized moving up and down and left rotation and right rotation of bell, can reach easily the switch of bell and the object that position is adjusted.When handwheel is clockwise during rotation hand wheel, screw mandrel departs from screw rodb base and moves up, and can move left and right around rotating seat simultaneously, and when counter clockwise direction rotation hand wheel, screw mandrel moves down, during to screw rodb base in impaction state, can not left rotation and right rotation.
