Description
Technical field
The present invention relates to a kind of Casting Equipment field, specifically a kind of slag-draining device.
Background technology
Slag inclusion is one of three big defects of casting industry.Foundry furnace is brought into because of life-time service, molten metal
Impurity constantly precipitates, and the refractory material of furnace wall also has part to be dissoluted and sink to furnace bottom in addition, skims every time
Touching fire door, furnace wall and furnace bottom causes refractory material to come off, and long is cumulative, foundry furnace one
After denier adds molten metal, above-mentioned impurity is that half suspended state is mixed in molten metal middle and lower part, at cast article
Time by stalk be cast in product generation slag inclusion.Holding furnace uses the time the longest, cast article slag inclusion
Ratio is the biggest.
Foundry furnace fire door is little, and very big inside foundry furnace, also has frangible thermometric pottery to protect in foundry furnace
Sheath, even if Mechanical Method cleaning residue under the blowing out state of cooling, easily causes the refractory material of bulk
Peel off, thus shorten converter life.Therefore in stove, cleaning is extremely difficult.So slag inclusion to be reduced, carry
Clear up in rising product quality, stove is a critically important factor.
Summary of the invention
For the deficiencies in the prior art, it is an object of the invention to provide a kind of slag-draining device, this deslagging fills
Put and can effectively the waste residue in foundry furnace be cleared up.
For achieving the above object, the technology used in the present invention means are as follows: a kind of slag-draining device,
For foundry furnace.This foundry furnace includes body of heater, stalk and mould.This stove is stretched in this stalk one end
Internal, other end connecting mold.This slag-draining device includes scum pipe and collecting device, this scum pipe one
End stretches in above-mentioned body of heater, and the other end connects collecting device.It is positioned at the above-mentioned scum pipe of above-mentioned body of heater
End is less than above-mentioned stalk end apart from above-mentioned bottom of furnace body apart from the distance of above-mentioned bottom of furnace body
Distance.Above-mentioned slag-draining device, when carrying out deslagging, connects slag-draining device with foundry furnace, passes through
Liquid in foundry furnace is entered collecting device together with waste residue by pressure.Owing to being positioned at the deslagging of this body of heater
Tube end distance bottom of furnace body is close, and waste residue is deposited in bottom of furnace body mostly, is thus advantageous to stove
Internal waste residue drains only.
Preferably, above-mentioned slag-draining device also includes pressure apparatus, and this pressure apparatus can make above-mentioned scum pipe
Interior generation negative pressure.Produce negative pressure in making above-mentioned scum pipe due to above-mentioned pressure apparatus, liquid in body of heater can be given
Body suction, with compared with adding malleation in body of heater, the suction in this scum pipe is more beneficial for deslagging pipe end
Waste residue around portion sucks.
The above-mentioned scum pipe end being preferably located in above-mentioned body of heater is provided with disturbance device.The most excellent
Selection of land, above-mentioned disturbance device includes the blade of fan shape, and this blade can flow into above-mentioned deslagging along with liquid
Manage and the rotation in this scum pipe circumference occurs.Owing to the above-mentioned scum pipe end in above-mentioned body of heater is arranged
There is disturbance device, liquid motion can be stirred, make waste residue be more readily pulled from bottom of furnace body, and then be discharged.
Owing to above-mentioned disturbance device includes the blade of fan shape, fan-shaped can be driven by the power of liquid flowing
The disturbance device of shape rotates, and then liquid is produced agitation.

Fig. 1 (a) is the partial sectional view schematic diagram of the foundry furnace 200 of the embodiment of the present invention；
Fig. 1 (b) is the partial sectional view that the slag-draining device 100 of the embodiment of the present invention connects body of heater 201
Schematic diagram.
Detailed description of the invention
As requested, the detailed description of the invention of the present invention will be disclosed here.It is to be understood, however, that
Embodiments disclosed herein is only the exemplary of the present invention, and it can be presented as various shape
Formula.Therefore, the detail disclosed here is not to be considered as limiting, and is merely possible to right
Require basis and as be used for instruct those skilled in the art in reality any appropriate in the way of
Differently apply the representational basis of the present invention, including using various features described herein and tying
Close and be likely not to have the feature clearly disclosed here.
As it is shown in figure 1, the embodiment of the present invention is a kind of slag-draining device 100, for foundry furnace 200.
Wherein, Fig. 1 (a) is the foundry furnace 200 partial sectional view schematic diagram when installing stalk 202, figure
1 (b) is the body of heater 201 partial sectional view schematic diagram when installing slag-draining device 100.Foundry furnace 200
Including body of heater 201, stalk 202 and mould (not shown).Body of heater is stretched in stalk 202 one end
In 201, other end connecting mold.Body of heater 201 internal memory is placed with the molten metal 203 of thawing, molten metal
203 are contained within waste residue 204.Bottom body of heater 201, waste residue more than 204.Slag-draining device 100
Including scum pipe 101 and collecting device 102.In addition on collecting device 102, also it is equiped with pressure
Power apparatus 103, wherein pressure apparatus 103 is air exhauster.Body of heater 201 is stretched in scum pipe 101 one end
In, the other end connects collecting device 102.It is positioned at the scum pipe 101 bottom distance stove of body of heater 201
The distance of the bottom of body 201 is less than the distance bottom the distance body of heater 201 of stalk 202 bottom, deslagging
Pipe 101 bottom is H with the difference in height of stalk 202 bottom.The end of scum pipe 101 in body of heater 201
End is additionally provided with disturbance device 104.Disturbance device 104 includes the blade of fan shape, and this blade can be with
Molten metal 203 to be inhaled into scum pipe 101 and the rotation in scum pipe 101 circumference occurs.
When remaining too much waste residue 204 in foundry furnace 200 needs to get rid of body of heater 201, by scum pipe
101 insert in body of heater 201, and carry out encapsulation process at scum pipe 101 and body of heater 201 seam.
The one end exposed by scum pipe 101 connects with collecting device 102, and both seams are carried out sealing
Process.Open pressure apparatus 103, by the molten metal 203 of the thawing in body of heater 201 together with waste residue 204
Suck collecting device 102.
The slag-draining device 100 of the present embodiment, due to scum pipe 101 bottom distance body of heater 201 bottom very
Closely, and waste residue 204 is deposited in bottom body of heater 201 mostly, and therefore the slag-draining device of the present embodiment more has
It is beneficial to drain the waste residue 204 in body of heater 201 only.Owing to providing negative pressure with air exhauster, pass through deslagging
Pipe 101 by the molten metal 203 in body of heater 201 together with waste residue 204 sucking-off body of heater 201, scum pipe 101
The suction of port is more beneficial for the waste residue 204 in disturbance body of heater 201, makes waste residue 204 easily be discharged
Body of heater 201.Owing to scum pipe 101 end is provided with disturbance device 104, on disturbance device 104
Blade can rotate along with the flowing of molten metal 203, and disturbance device 104 both need not be additionally provided
Power, creates again the effect of agitation to the waste residue 204 in body of heater 201, makes waste residue 204 easily take off
From body of heater 201 and then be discharged.
