Description
Technical field
This utility model is related to lost foam casting apparatus, the dustless sandbox of specifically a kind of lost foam casting.
Background technology
In lost foam casting production process, need to carry out the yellow mould in sandbox plus sand molding.During sand is added, make
The dust carried on type fine sand inevitably can be spread to above sandbox, and this operating environment to moulding workman causes extremely tight
The pollution of weight.At present, the method for traditional dedusting is that the surrounding of the raining-type sand filling device above sandbox does dust removal installation, is such as being drenched with rain
Plus dedusting air flue is done in four sides of sand device, there is dedusting aperture four sides, and each air flue side is done 1 dust removal port and is passed through dedusting system
In system.The dedusting structure can prevent from stirring up a cloud of dust to a certain extent, and reach expected dust removing effects, but, there is also
Many defects below：1. dust arrester is made in the side above the sandbox, needs the surrounding below raining-type sand filling device to reserve and does gas
The passage of room, sand storage bin accommodate the height of molding sand and at least lose 200mm；2. dust arrester is made above sandbox, it is desirable to have enough
Big air quantity, when sandbox top surface apart from raining-type sand filling device farther out when, then may require that bigger air quantity, be difficult to reach if deficiency in draught
To preferable dust removing effects；3. the setting of this structure only just has dust removing effects when sandbox is below raining-type sand filling device, but
It is that, in the case where actual production beat is compact, the sandbox after generally requiring to add sand moves quickly into next station, and
When now the dust on sandbox is not also blotted net, can be diffused in air with part airborne dust when sandbox is removed.
Utility model content
The purpose of this utility model is just to provide a kind of dustless sandbox of lost foam casting, to solve Lost Form Casting Production Line
Have in upper existing sandbox that dedusting structure design is unreasonable, take the storage sand space of sand storage bin, using position have compared with big limitation,
The undesirable problem of dust removing effects.
What the purpose of this utility model was realized in：A kind of dustless sandbox of lost foam casting, including casing, it is arranged on case
The negative pressure chamber of body bottom, the negative pressure ventilation mouth being arranged on wall box, the negative pressure chamber are logical with the negative pressure ventilation mouth
Cross air flue to be connected, dust removal port is provided with the side wall of the casing, is provided between the dust removal port and the negative pressure chamber and is removed
Dust and gas road.
The outer wall top of the casing is provided with sandbox hoisting axis.
Ribs is provided with the transversal centerline of the cabinet exterior.
The dust removal port be arranged on below sandbox hoisting axis and above ribs between casing wall on.
It is provided with dust removal port for controlling the valve of the dust removal port opening and closing of fault, the valve is ball valve, butterfly valve
Or gate valve.
The negative pressure ventilation mouth is dust removal port, is provided with for dust removal port is connected in the port of the negative pressure ventilation mouth
Dedusting automatic butt device in dust pelletizing system.
This utility model eliminates the structure of the dedusting air chamber of top setting in conventional art on the basis of original sandbox,
Increased dust removal port and its with negative pressure chamber identical dedusting air flue, so take full advantage of the knot of the original negative pressure chamber of sandbox
Structure feature, has saved the existing production cost for making special air chamber, increased the space shared by the dedusting air chamber of top again, is storage
Sand hopper stores more molding sand there is provided possible.Additionally, dedusting structure of the present utility model is designed, required dedusting air quantity is little, and
Air quantity is not affected apart from sandbox distance by raining-type sand filling device, and efficiency of dust collection is high, it is crucial that when sandbox removes raining-type sand filling
During scope below device, dedusting is can also continue to, is not in cause the problem of afterbody airborne dust as sandbox is worked continuously.It is comprehensive
Upper described, this utility model structure design advantages of simple, low production cost improve the utilization space above sandbox, required dedusting
Air quantity is little, and without afterbody airborne dust, efficiency of dust collection is high, is suitable to promote the use of in evaporative pattern is produced.
