Abstract
The utility model relates to a filtering device of a metal fused solution applied to low-pressure casting. The filtering device comprises a shell, wherein a chute piece made of a refractory material is arranged in the shell, and is provided with a chute; the bottom of the chute is provided with a through hole; the chute is communicated with the outer side of the bottom of the shell through the through hole; a the filter screen is arranged above the chute; and the shell is further provided with a fixing mechanism for fixing the filter screen. According to the technical scheme of the utility model, the effect of effectively removing bubbles, oxide entrapped slag and other various impurities in a metal fused solution is achieved in the production process of low-pressure casting.
Description
Technical field
The utility model relates to a kind of filter, is specifically related to a kind of filter of the point molten metal for low pressure casting.
Background technology
Be used for the metal (such as aluminium alloy) of low pressure casting at fusion process, point molten metal is often residual a bubble, the oxide slag inclusion, and the objectionable impurities such as various field trashes, by melting furnace through casting ladle in the transmission course of holding furnace, the furnace wall, the casting ladle wall is also often fallen into block refractory material, reduced greatly the mechanical property of material, especially the slag inclusion of those bulks is coated on foundry goods inside, the surface can't detect, the existence of these slag inclusions has reduced the net sectional area of part, and in the loading process of part, the slag inclusion position is caused and is easily caused stress to concentrate, and part can not satisfy job requirement, to such an extent as to suddenly fracture causes major accident in the course of work.Can put at the cast gate place screen pack in gravity casting process, gear is except these slag inclusions, but in large batch of low pressure casting was produced, screen pack can't be laid by the cast gate place, and various defectives are brought into foundry goods inside, often make part not reach test stone.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is to provide in a kind of low pressure casting production process, effectively removes the filter of bubble in the point molten metal, oxide slag inclusion and other various field trashes.
For achieving the above object, the utility model provides following technical scheme: a kind of filter of the point molten metal for low pressure casting, comprise housing, described housing Inner is provided with the chute spare that refractory material consists of, be provided with chute on the described chute spare, described chute bottom arranges through hole, and the outside of described chute and housing bottom is conducted by described through hole, described chute top is provided with screen pack, also is provided with the fixedly fixed mechanism of screen pack on the described housing.
By adopting technique scheme, be used for the metal of low pressure casting after melting furnace dissolves, point molten metal is imported in the casting ladle, before further importing holding furnace, put the filter of technical solutions of the utility model at holding furnace, then the point molten metal in the casting ladle is slowly poured into to filter, point molten metal enters in the chute by screen pack, then flow in the holding furnace by through hole, thereby effectively removed bubble in the point molten metal, oxide slag inclusion and other various field trashes.
The utility model further arranges: described fixed mechanism comprises quick-speed jigs and slotted-angle shelving, described quick-speed jigs comprises bracing frame, motion arm and clamping head, support frame as described above is fixedly connected with described housing, and described screen pack is folded between described clamping head and the slotted-angle shelving.
Because the service life of screen pack is usually not long, by adopting technique scheme, screen pack can change fast by quick-speed jigs, and screen pack can cooperate firm being fixed in the filter by clamping head with slotted-angle shelving after using once.
The utility model further arranges: also be provided with pressing plate between described screen pack and the clamping head, described screen pack is folded between pressing plate and the slotted-angle shelving.
By adopting technique scheme, further improved the steadiness of screen pack in filter.
Below in conjunction with accompanying drawing the utility model is further described.

The specific embodiment
Referring to accompanying drawing 1 to accompanying drawing 4, the filter 2 of the disclosed point molten metal for low pressure casting of the utility model, comprise housing 21, described housing 21 Inner are provided with the chute spare 22 that refractory material consists of, be provided with chute 23 on the described chute spare 22, described chute 23 bottoms arrange through hole 24, and described chute 23 is conducted by described through hole 24 with the outside of housing 21 bottoms, described chute 23 tops are provided with screen pack 25, also are provided with the fixedly fixed mechanism 26 of screen pack 25 on the described housing 21.Screen pack 25 preferably is made of high-temperature fibre aluminium water filtration screen cloth.By adopting technique scheme, be used for the metal of low pressure casting after melting furnace dissolves, point molten metal is imported in the casting ladle 1, before further importing holding furnace 3, put the filter 2 of technical solutions of the utility model at holding furnace 3, then the point molten metal in the casting ladle 1 is slowly poured into to filter 2, point molten metal enters in the chute by screen pack 205, then flow in the holding furnace 3 by through hole 24, thereby effectively removed bubble in the point molten metal, oxide slag inclusion and other various field trashes.
The present embodiment further arranges: described fixed mechanism 26 comprises quick-speed jigs 261 and slotted-angle shelving 262, described quick-speed jigs 261 comprises bracing frame 2611, motion arm 2612 and clamping head 2613, support frame as described above 2611 is fixedly connected with described housing 21, and described screen pack 25 is folded between described clamping head 2613 and the slotted-angle shelving 262.Because the service life of screen pack 25 is usually not long, by adopting technique scheme, after screen pack 25 uses once, can by quick-speed jigs 261 easily and fast change operation, and screen pack 25 can cooperate firm being fixed in the filter 2 by clamping head 2613 with slotted-angle shelving 262.
The present embodiment further arranges: also be provided with pressing plate 263 between described screen pack 25 and the clamping head 2613, described screen pack 25 is folded between pressing plate 263 and the slotted-angle shelving 262.By adopting technique scheme, further improved the steadiness of screen pack 25 in filter 2.
