Description
Technical field
The utility model is related to steel-making additive preparation equipment technical field, more particularly to molten-steel deoxidation agent production is with removing
Dirt device.
Background technology
To ensure the smooth casting of molten steel, and qualified steel are rolled into, need to be added into ladle in tapping certain
The deoxidier of amount carries out deoxidation treatment, while appropriate alloy is added according to steel grade specification requirement and adjusts chemical composition.Usually production
The first step of molten-steel deoxidation agent is that the raw materials such as various raw materials, such as calcium aluminate, aluminum shot are stirred mixing, is made to be subsequent
The processes such as grain, blocking, ingot processed are prepared.
It includes transporter and blender, wherein transporter to be currently used for the agitating device that molten-steel deoxidation agent raw material is stirred
Including motor-driven shaft and band is transported, and blender includes agitator and motor-driven agitating shaft, is wherein set in shaft
There are multiple stirring blades, using transporter by various feedstock transportations into being stirred in blender, raw material is stirred reaching
Above machine, the air-flow generated in the stirring blade and blender that are impacted in blender during whereabouts can all make raw material
Middle amount of powder can raise up, and form flying dust in air, cause greatly to threaten to the health of worker；Additionally, due to the de- of production
Oxygen agent must keep drying, therefore cannot be dusted processing in stirring technique by the way of water spray, therefore just need to existing
There is the stirring technique in technology to be improved processing, is formed in air when molten-steel deoxidation agent raw materials for production being avoided to stir a large amount of
Flying dust.
Utility model content
The utility model is intended to provide when one kind can prevent molten-steel deoxidation agent raw materials for production from stirring and be formed in air greatly
Measure the dust-extraction unit of flying dust.
In order to achieve the above object, the base case of the utility model is：
Molten-steel deoxidation agent production dust-extraction unit, is mounted on the top of blender and transporter, including removes dirt cup, described to remove
Dirt cup is coaxially connected at the top of agitator, described to have partition board except horizontally disposed in dirt cup, and dirt cup side wall is removed below the partition board
On offer feed inlet, the lower surface of the partition board is equipped with separating plate；
The partition board is equipped with dust hood and dust excluding hood positioned at separating plate both sides, and the dust hood is close to feed inlet one
There is cylinder in side above partition board except horizontally disposed in dirt cup, and it is unidirectional to be equipped with air inlet on the cylinder sidewall of cylinder piston both sides
Valve and outgassing nonreturn valve, breather check valve are connected to dust hood, and outgassing nonreturn valve is connected to dust excluding hood, and cylinder piston rod is stretched
Go out except dirt cup and is connected with the rack being connect with housing slide；
Further include disk, the disk is fixed on the roller end below rack, and convex block is eccentrically provided on the disk,
It is additionally provided with the swing component being rotatably connected in rack below rack, the swing component includes swing arm and the fan for being connected to swing arm upper end
Shape gear, the sector wheel and rack engagement, the swing arm are equipped with the groove slided for convex block.
The operation principle of this base case is：
After blender and conveyor starting, the shaft in transporter is rotated by motor, to drive roller end
Disk rotational, it is that movement interference occurs in order to avoid swing arm and the shaft of swing component that disk, which is arranged in the end of shaft, herein,
It since convex block is eccentrically arranged in disk upper surface, and is rotatably connected in rack with the swing component of convex block cooperation, therefore convex
Block can drive swing component to rotate, i.e., when convex block is clockwise to left end with disk from right end, swing arm also can edge
It clockwise swings, and sector gear rotates along clockwise direction simultaneously, by being engaged with rack so that tooth
Item moves right, to which pusher cylinder piston moves to the right；It is most right as disk is clockwise to from left end in convex block
When end, swing arm can rotate counterclockwise, while sector gear rotates in the counterclockwise direction, by being nibbled with rack
It closes so that rack is moved to the left, to pull cylinder piston to move to the left.
While cylinder piston moves back and forth, upward negative pressure is generated at dust hood by the breather check valve of both sides
Power, and the gas for sucking cylinder is squeezed by outgassing nonreturn valve to dust excluding hood；Since the raw material being transported in agitator is under
It is hit with stirring blade during falling, and stirring blade will produce certain air-flow during stirring, to
So that part material powder raises up；Due to being in the state of negative pressure below dust hood, dust below dust hood can be by
The effect of negative pressure enters in cylinder, and the air-flow for having cylinder to be discharged at dust excluding hood, the downward active force of air-flow can suppress powder
Dirt is flown upward upwards, and enters the dust in cylinder as outgassing nonreturn valve is from dust excluding hood discharge, when the dust of discharge reaches
When a certain amount of, it is based ultimately upon the downward effect of air-flow and gravity re-enters into agitator.
This base case has technical effect that：
1, the base case of the utility model solve in the prior art deoxidier raw materials for production stirring when in air
The problem of forming a large amount of flying dust ensure that the health of operating personnel, while also obtain the production environment for meeting environmental requirement.
2, the power of transporter is cleverly utilized without in addition setting power source, dust-extraction unit in the utility model, operates
Personnel open transporter after dust-extraction unit i.e. start to work, transporter close after dust-extraction unit be also stopped, in this way with transport
The work that machine synchronizes, has saved power, has decreased the additional manipulation processes of operating personnel.
3, the negative pressure formed below dust hood in the utility model avoids the dust that raises up in agitator from opening
It enters in external environment, while by dust absorbing air return cylinder, and the air-flow that dust excluding hood is discharged downwards, to raising up in agitator
Dust form downward extruding force, in addition absorb inlet casing dust from dust excluding hood be discharged, air-flow extruding force and itself weight
It is come back in agitator under power, realizes the recovery processing to raw material dust.
Further, the separating plate is obliquely installed, and inclined-plane is towards feed inlet direction.In this way separating plate can stop portions raise
Dust enter the lower section of dust hood, to avoid when dust is excessive dust hood have little time to adsorb, to be arranged by feed inlet
Go out to outside dust-absorbing tube.
Further, described except dirt cup is bolted with agitator by multiple.Be provided in this way, on the one hand can directly by
Dust-extraction unit is mounted on existing agitator, without carrying out larger change to the agitating device newly having, is reduced cost and is paid；
On the other hand, when agitating device failure needs internal overhaul, with the connection of such connection type except dirt cup facilitates repair
Personnel dismantle.
Further, described remove is hinged with cover board at the top of dirt cup.It is provided in this way：On the one hand convenient that cylinder is examined
It repaiies, on the other hand avoids the dust accumulation of air on partition board, be not only difficult to clear up, will also result in some potential safety problems.
Further, described except dirt cup is circumferentially with supporting rack.Due to being directly installed on agitator except dirt cup, and stir
It mixes bucket and has certain vibration in stirring work, in order to ensure the production safety except dirt cup, and extend making for dust-extraction unit
With the service life, supporting rack is being set except dirt cup surrounding, to reduce the vibration of agitator to the influence except dirt cup.
