Description
Technical field
The utility model relates to a kind of Casting Equipment field, specifically a kind of slag-draining device.
Background technology
Slag inclusion is one of three large defects of casting industry.Foundry furnace is because of Long-Time Service, the impurity that molten metal is brought into constantly precipitates, in addition the refractory material of furnace wall also has part to be dissoluted and to sink to furnace bottom, skim at every turn and cause refractory material to come off to fire door, furnace wall and touching of furnace bottom, of a specified duration is cumulative, foundry furnace is once after adding molten metal, and above-mentioned impurity is that half suspended state is mixed in molten metal middle and lower part, is cast in product produces slag inclusion when cast article by stalk.Holding furnace is longer for service time, and cast article slag inclusion ratio is larger.
Foundry furnace fire door is little, and foundry furnace inside is very large, also has frangible thermometric ceramic protective sleeve in foundry furnace, even if Mechanical Method clears up residue under the blowing out state of cooling, very easily causes the shelling of refractory of bulk, thus shortens converter life.Therefore in stove, cleaning is very difficult.So will reduce slag inclusion, Improving The Quality of Products, in stove, cleaning is a very important factor.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of slag-draining device, and this slag-draining device can effectively be cleared up the waste residue in foundry furnace.
For realizing above-mentioned utility model object, the technological means that the utility model adopts is as follows: a kind of slag-draining device, for foundry furnace.This foundry furnace comprises body of heater, stalk and mould.This stalk one end is stretched in this body of heater, other end connecting mold.This slag-draining device comprises scum pipe and collecting device, and this scum pipe one end is stretched in above-mentioned body of heater, and the other end connects collecting device.The above-mentioned scum pipe end being positioned at above-mentioned body of heater is less than the distance of above-mentioned stalk end apart from above-mentioned bottom of furnace body apart from the distance of above-mentioned bottom of furnace body.Above-mentioned slag-draining device, when carrying out deslagging, connecting slag-draining device and foundry furnace, by pressure, the liquid in foundry furnace being entered collecting device together with waste residue.Because the scum pipe end distance bottom of furnace body being positioned at this body of heater is very near, and waste residue is deposited in bottom of furnace body mostly, is therefore conducive to the waste residue in body of heater to drain only.
Preferably, above-mentioned slag-draining device also comprises pressure apparatus, and this pressure apparatus can make to produce negative pressure in above-mentioned scum pipe.Because above-mentioned pressure apparatus makes to produce negative pressure in above-mentioned scum pipe, can give liquid suction in body of heater, and adding compared with malleation in body of heater, the suction in this scum pipe is more conducive to the waste residue of scum pipe end perimeter to suck.
Preferably, the above-mentioned scum pipe end being positioned at above-mentioned body of heater is provided with disturbance device.More preferably, above-mentioned disturbance device comprises the blade of fan shape, the rotation that this blade can flow into above-mentioned scum pipe along with liquid and occur in this scum pipe circumference.Because the above-mentioned scum pipe end in above-mentioned body of heater is provided with disturbance device, agitated liquid can move, make waste residue more easily depart from bottom of furnace body, and then be discharged.Because above-mentioned disturbance device comprises the blade of fan shape, the disturbance device of fan-shaped can be driven to rotate by the power of liquid flow, and then stirring is produced to liquid.
accompanying drawing explanation

Fig. 2 is the partial sectional view schematic diagram that the slag-draining device 100 of the utility model embodiment connects body of heater 201.
detailed description of the invention
As requested, detailed description of the invention of the present utility model will be disclosed here.But should be understood that, embodiment disclosed is here only exemplary of the present utility model, and it can be presented as various forms.Therefore, here the detail disclosed is not considered to restrictive, and be only as the basis of claim and as instructing those skilled in the art differently to apply representational basis of the present utility model in appropriate mode any in reality, the various features comprising employing disclosed here also combine the feature that may clearly not disclose here.
As shown in Figure 1, the utility model embodiment is a kind of slag-draining device 100, for foundry furnace 200.Wherein, Fig. 1 is the partial sectional view schematic diagram of foundry furnace 200 when installing stalk 202, and Fig. 2 is the partial sectional view schematic diagram of body of heater 201 when installing slag-draining device 100.Foundry furnace 200 comprises body of heater 201, stalk 202 and mould (not shown).Stalk 202 one end is stretched in body of heater 201, other end connecting mold.Body of heater 201 internal memory is placed with the molten metal 203 of thawing, containing waste residue 204 in molten metal 203.Bottom body of heater 201, waste residue more than 204.Slag-draining device 100 comprises scum pipe 101 and collecting device 102.In addition on collecting device 102, be also equiped with pressure apparatus 103, wherein pressure apparatus 103 is air exhauster.Scum pipe 101 one end is stretched in body of heater 201, and the other end connects collecting device 102.The distance being positioned at the bottom of the scum pipe 101 bottom distance body of heater 201 of body of heater 201 is less than stalk 202 bottom apart from the distance bottom body of heater 201, and the difference in height of scum pipe 101 bottom and stalk 202 bottom is H.In body of heater 201, the bottom of scum pipe 101 is also provided with disturbance device 104.Disturbance device 104 comprises the blade of fan shape, and this blade can be inhaled into scum pipe 101 along with molten metal 203 and occur along the rotation in scum pipe 101 circumference.
When foundry furnace 200 needs to get rid of waste residue 204 residual too much in body of heater 201, scum pipe 101 is inserted in body of heater 201, and carries out encapsulation process at scum pipe 101 and body of heater 201 interface.The one end of being exposed by scum pipe 101 is communicated with collecting device 102, and both interfaces are carried out encapsulation process.Opening pressure device 103, sucks collecting device 102 by the molten metal 203 of the thawing in body of heater 201 together with waste residue 204.
The slag-draining device 100 of the present embodiment, due to very near bottom the distance body of heater 201 of scum pipe 101 bottom, and waste residue 204 is deposited in bottom body of heater 201 mostly, and therefore the slag-draining device of the present embodiment is more conducive to the waste residue 204 in body of heater 201 to drain only.Owing to providing negative pressure with air exhauster, by scum pipe 101 by the molten metal 203 in body of heater 201 together with waste residue 204 sucking-off body of heater 201, the suction of scum pipe 101 port is more conducive to the waste residue 204 in disturbance body of heater 201, makes waste residue 204 easily be discharged body of heater 201.Because scum pipe 101 end is provided with disturbance device 104, blade on disturbance device 104 can rotate along with the flowing of molten metal 203, disturbance device 104 neither needs additionally to provide power, again the waste residue 204 in body of heater 201 is created to the effect of stirring, make waste residue 204 easily depart from body of heater 201 and then be discharged.
Technology contents of the present utility model and technical characterstic have disclosed as above; but be appreciated that; under creative ideas of the present utility model; those skilled in the art can make various changes said structure and material and improve; comprise the combination of disclosure or claimed technical characteristic separately here, comprise other combination of these features significantly.These distortion and/or combination all fall in the technical field involved by the utility model, and fall into the protection domain of the utility model claim.
