Abstract
The utility model provides a multi-stage filter for purifying metals and belongs to the technical field of metallurgy. The multi-stage filter comprises a filter body, three filtering elements of different pore sizes, and a plurality of filtration holes uniformly distributed on each filtering element. The multi-stage filter has the advantages as follows: the filtering elements of different pore sizes are used to not only remove large-size inclusion particles in molten metal but also remove small-size inclusion particles in the molten metal, so that the purity of the molten metal is significantly improved and thus the quality of metallurgic products is excellent. Besides, the arrangement of the filtering elements can stabilize the flow state of the molten metal in the filter and facilitate the smooth implementation of refining operation.
Description
Technical field
The utility model belongs to metallurgical technology field, relates to a kind of purification metal multistage filter.
Background technology
In recent years, along with the challenge aggravation that metallurgy industry faces in market competition, the user improves constantly the requirement of metallurgic product quality, thereby has produced the production technology of multiple raising metallurgic product.Owing to filter has the advantages such as simple in structure, that making is easy, easy for installation, practical, casting, metallurgy, aluminium alloy extrusions and chemical field have been widely used in.In the refining operation of reality, the metallargist generally adopts the filter in single aperture to remove field trash in the molten metal, causes easily filter to remove the poor effect that is mingled with.If select the large aperture filter, can only remove the large inclusions in the molten metal, and short grained field trash is not easy to remove; If select the small-bore filter, filter can catch the granule field trash well, but the easy blocking filter of large-sized inclusion particle.The selection of single aperture filter, often so that the quality of final metallurgic product can not be guaranteed.
The utility model content
The purpose of this utility model is to provide a kind of purification metal multistage filter, solves above-mentioned technical problem.
To achieve these goals, the technical solution of the utility model is: a kind of purification metal multistage filter, and its feature comprises the filter element of filter body 1 and three kind of different pore size, some filter bores evenly distribute on every kind of filter element; Filter element is: 10PPI aperture filter element 2,30PPI aperture filter element 3,45PPI aperture filter element 4, install along the distribution sequence of the mobile direction of molten metal, all with 1 firm connection of filter body; Filter bores is 10PPI aperture filter bores 5,30PPI aperture filter bores 6,45PPI aperture filter bores 7.
Further, in the technique scheme, the shape of described 10PPI aperture filter bores 5,30PPI aperture filter bores 6,45PPI aperture filter bores 7 is manhole.
Further, in the technique scheme, the direction of described 10PPI aperture filter bores 5,30PPI aperture filter bores 6,45PPI aperture filter bores 7 is parallel to the flow direction of molten metal.
Superior part of the present utility model is: the use of different pore size filter element, both can remove the large-sized inclusions particle in the molten metal, can remove again the small size inclusion particle in the molten metal, the cleanliness factor of molten metal is significantly improved, and finally metallurgic product is superior in quality; Simultaneously, the flow regime of filter inner metal liquid has been stablized in the setting of filter element, is conducive to the direct motion of refining operation.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Fig. 1: purify metal multistage filter structural representation.
Fig. 2: the cutaway view of A-A face among Fig. 1.
Fig. 3: the cutaway view of B-B face among Fig. 1.
Fig. 4: the cutaway view of C-C face among Fig. 1.
Wherein: 1-filter body, 2-10PPI aperture filter element, 3-30PPI aperture filter element, 4-45PPI aperture filter element, 5-10PPI aperture filter bores, 6-30PPI aperture filter bores, 7-45PPI aperture filter bores
The specific embodiment
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, a kind of purification metal multistage filter, comprise filter body 1,10PPI aperture filter element 2,30PPI aperture filter element 3,45PPI aperture filter element 4,10PPI aperture filter bores 5,30PPI aperture filter bores 6,45PPI aperture filter bores 7.The direction of filter bores 5, filter bores 6, filter bores 7 all is parallel to the flow direction of molten metal.When carrying out refining operation, molten metal at first flows into from the import of filter left end, passes through respectively filter element 2, filter element 3 and filter element 4, then flows out from the outlet of filter right-hand member.In the said process, the successively distribution of 10PPI aperture filter element 2,30PPI aperture filter element 3 and 45PPI aperture filter element 4, to catch respectively large-sized inclusions particle and small size inclusion particle, the cleanliness factor of molten metal is significantly improved, and finally metallurgic product is superior in quality.Simultaneously, steady from the mobile state of molten metal that 45PPI aperture filter bores 7 flows out, be conducive to the direct motion of refining operation.
