Description

A kind of twin-stage plate-type filtering case

Technical field

The utility model relates to aluminum casting production equipment technologies, and in particular to a kind of twin-stage plate-type filtering case.

Background technique

Aluminium is a kind of metallic element, strong but pliable in texture and light, there is ductility, is easy conduction.Can make aircraft, vehicle, ship, oceangoing ship, The structural material of rocket.The cable aluminium that fine aluminium can do extra-high voltage is the current maximum metal of dosage, ground in addition to steel in the world The most abundant metallic element of content in shell, content 8.3%.Mainly exist with aluminum silicate minerals, there are also bauxite and ice crystal. Aluminium oxide is a kind of white amorphous powder, and there are many variants for it, wherein the most familiar to people is α-Al2O3 and β- Al2O3.Corundum existing for nature belongs to α-Al2O3, its hardness is only second to diamond, and fusing point height, acid and alkali-resistance are commonly used to Some bearings are made, abrasive material, refractory material are manufactured.Such as corundum crucible, it is resistant to 1800 DEG C of high temperature.Al2O3 is due to containing difference Impurity and there are many color.Such as taking on a red color containing trace Cr (III), referred to as ruby；Containing Fe (II), Fe (III) or Ti's (IV) is known as sapphire, and the use scope of aluminium is quite extensive.With China's expanding economy, aluminum products are being produced and are being lived In dosage it is increasing, aluminum products industry is in the fast-developing stage.Just before aluminium and aluminium alloy casting, need to molten aluminum Carry out the processing of the techniques such as preparatory filtration, purification.

Aluminium and aluminium alloy would generally be mingled with a certain amount of impurity in fusion process, and processing side must be filtered before casting It can remove, plate-type filtering is one of the most common type method in numerous aluminium melting liquid filtrate methods, has the spies such as at low cost, easy to maintain Point is able to satisfy conventional aluminium melting liquid filtrate required precision, and therefore, in actual production, most aluminium and aluminium alloy Foundry Production are adopted With plate-type filtering technique.

Common plate-type filtering case has two kinds of patterns of single-stage Rose Box and double-stage filtering case, and single-stage filtering case apparatus is only arranged one Block filter plate, the occasion of less demanding suitable for filtering accuracy, twin-stage plate-type filtering device pass through the filter plate string of front and back second level Higher filtering accuracy can be achieved in connection use, obtains cleaner aluminum melt quality.

In practical application, there are many structure types to become with the difference that technology arrangement requires for twin-stage plate-type filtering case inner lining structure Change, basic demand be it is identical, it is specific as follows:

1. cabinet inner lining structure is stable, does not crack, ball non-sticky to aluminum, long service life

2. residual aluminum amount is few in case

3. filter plate is easily changed

4. filter plate installation stablizes, does not leak aluminium, filter plate does not float.

But existing twin-stage plate-type filtering case compact inner lining structure can not reach above-mentioned requirements, especially in life It produces, during design, the problems such as residual aluminum amount is more, filter plate easily floats in there is whole cabinets easy to crack, case.

Utility model content

The purpose of this utility model is to provide a kind of twin-stage plate-type filtering case, avoid that whole cabinet is easy to crack, in case The problems such as residual aluminum amount is more, filter plate easily floats.

The utility model provides a kind of twin-stage plate-type filtering case, includes cabinet, setting is connected on the cabinet Enter aluminium chute liner, higher level's Rose Box liner, junior's Rose Box liner and aluminium chute liner out with melt circulation passage, Filter plate is set in higher level's Rose Box, junior's Rose Box, the melt circulation passage higher level's Rose Box liner, under Lining is arranged as making aluminum melt to flow from top inflow, after the filter plate by the side of the filter plate in grade Rose Box Out, it is described enter aluminium chute liner, higher level's Rose Box liner, junior's Rose Box liner and aluminium chute liner is all made of ball non-sticky to aluminum and pours out Material feeding is pre-formed, enters aluminium mouth positioned at the same side wherein being provided in higher level's Rose Box liner, junior's Rose Box liner And aluminium flowing-out mouth.

Further, it is described enter aluminium chute liner, higher level's Rose Box liner, junior's Rose Box liner and aluminium chute liner out Inner lining material uses ball non-sticky to aluminum castable.

Further, the ball non-sticky to aluminum castable is the quartziferous ball non-sticky to aluminum castable of low Linear change rate.

Further, the ball non-sticky to aluminum castable is the silicon carbide ball non-sticky to aluminum castable of low Linear change rate.

Beneficial effect using above-mentioned technical solutions of the utility model is: a kind of twin-stage plate-type filtering of the utility model Case, designed double-stage filtering case liner use precast block splicing structure, avoid whole cabinet problem easy to crack；By each The position that grade filter plate enters aluminium mouth and aluminium flowing-out mouth is arranged, and realizes compact overall structure and the small function of residual aluminum amount；Also excellent simultaneously Molten aluminum circulation path is changed, aluminum melt all from the top through filter plate, preferably resolves filter plate and easily floats problem.
