Abstract
The invention discloses a composite purifying box for zinc and zinc alloy melts. A heat-resistant steel inner container is fixedly connected in a bracket, and is partitioned into a front purifying chamber, a back purifying chamber and a chute front chamber from front to back in sequence; the bottom surface of the heat-resistant steel inner container inclines towards the chute front chamber by a certain angle; a prefabricated refractory material groove is formed below the bottom surface of the heat-resistant steel inner container; a heating element is arranged in the prefabricated refractory material groove; the bottom end of the front purifying chamber and the bottom end of the back purifying chamber are provided with air blowing plug respectively; a rough-hole foam ceramic filter plate is arranged between the front purifying chamber and back purifying chamber; a fine foam ceramic filter plate is arranged between the back purifying chamber and the chute groove front chamber; and the bottom end of the side wall of the chute groove front chamber is connected with a plug. The composite purifying box has the advantages that: due to the designs of the heat-resistant steel inner container and a clapboard, the composite purifying box is convenient to manufacture and replace, and the service life is long. The foam ceramic filter plate is easy to fix, install and replace.
Description
Technical field
The present invention relates to a kind of purifying box, relate in particular to a kind of zinc and zinc alloy melt composite purification case.
Background technology
Cleaning molten is the gordian technique that guarantees the alloy material metallurgical quality, and the purpose of zinc alloy cleaning molten mainly is gas content, oxide inclusion and the intermetallic compound that reduces in the melt.Traditional zinc alloy purifies the methods such as leaving standstill clarification, villaumite processing, rare gas element blowing and filtration that can adopt.It is that villaumite is handled that prior art generally adopts solvent refined, and the refining agent main component is NH
4Cl or ZnCl
2Add a spot of carbonate or nitrate and form, utilize villaumite under the zinc alloy smelting temperature, to gasify and separate out a large amount of microbubbles, impel interior gas of alloy and inclusion to be attached to bubble floating, reach the purpose of removal.It is boundless and indistinct in factory that this method of refining discharges pungencys such as zinc chloride, ammonia very strong toxic gas and smog, causes serious environmental pollution, and the harm operator is healthy, and corrosion factory building and equipment are not allowed by modern production.Also have and use fine grain ceramics build-up of particles place mat to become certain thickness strainer to carry out filtration, purification,, can remove in the ZZnAl4-1 alloy liquid nearly 90% oxide compound and 85% intermetallic compound though this method decontamination effect improving is better.But install loaded down with trivial detailsly, filtration yield is very little, can only be used for the little Zinc alloy casting cast of tens of kilogram weights.At present, a large amount of zinc alloy furnace external purifying technology do not obtain exploitation as yet.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of zinc and zinc alloy melt composite purification device are provided.
The present invention is achieved like this, it comprises support, the high temperature steel inner bag, preceding decontamination chamber, the after chamber, the chute cup, prefabricated tundish, heating unit, purge plug, the gross porosity foamed ceramic filter plate, the fine foam ceramic filter plate, plug, it is characterized in that the support internal fixing is connected with the high temperature steel inner bag, the high temperature steel inner bag is divided into preceding decontamination chamber from front to back successively, after chamber and chute cup, the bottom surface of high temperature steel inner bag is angle and tilts to the chute cup, the below, bottom surface of high temperature steel inner bag is provided with prefabricated tundish, be provided with heating unit in the prefabricated tundish, the bottom of the bottom of preceding decontamination chamber and after chamber is respectively equipped with purge plug, be provided with the gross porosity foamed ceramic filter plate between preceding decontamination chamber and the after chamber, be provided with the fine foam ceramic filter plate between after chamber and the chute cup, the sidewall bottom of chute cup is connected with plug.
The pore diameter range of described foamed ceramic filter plate is 10-40ppi, and the thickness of foamed ceramic filter plate is 40 ~ 60mm.
Advantage of the present invention is: by being blown into bubble and two-stage foam ceramic filter composite purification, foamed ceramic filter plate is difficult for stopping up, attemperator guarantees that the zinc alloy melt has good flowability, can realize a large amount of zinc alloy furnace external purifyings, filtering accuracy can reach the above oxide removal efficiency of 10 μ m more than 90%, FeAl
3Deng the intermetallic compound clearance more than 85%.The design of high temperature steel inner bag and dividing plate is convenient to make and change long service life.Foamed ceramic filter plate is easy to fixed installation and changes.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1, the present invention is achieved like this, support 1 internal fixing is connected with high temperature steel inner bag 2, high temperature steel inner bag 2 is divided into preceding decontamination chamber 3 from front to back successively, after chamber 4 and chute cup 5, the bottom surface of high temperature steel inner bag 2 is angle and tilts to chute cup 5, the below, bottom surface of high temperature steel inner bag 2 is provided with prefabricated tundish 6, be provided with heating unit 7 in the prefabricated tundish 6, the bottom of the bottom of preceding decontamination chamber 3 and after chamber 4 is respectively equipped with purge plug 8, be provided with gross porosity foamed ceramic filter plate 9 between preceding decontamination chamber 3 and the after chamber 4, be provided with fine foam ceramic filter plate 10 between after chamber 4 and the chute cup 5, the sidewall bottom of chute cup 3 is connected with plug 11, gross porosity, fine foam ceramic filter plate 9,10 pore diameter range is 10-40ppi, and the thickness of foamed ceramic filter plate is 40 ~ 60mm.During use, after zinc alloy enters preceding decontamination chamber 3, the drying nitrogen that enters by purge plug 8 slowly rises in preceding decontamination chamber 3 with the form of micro-bubble, with descending melt-mixing collision, the oxide inclusion and the intermetallic compound that adsorb simultaneously in the melt float it thereupon, arrive the melt top, form scum silica frost, melt by the gas rough purification passes through first step gross porosity foamed ceramic filter plate 9 then, and the above inclusion of most 50 μ m all is removed.After the zinc alloy melt enters the after chamber, mix mutually with the micro-bubble that purge plug 8 blows out again, some very tiny inclusiones are taken away come-up by bubble again, fine foam ceramic filter plate 10 can will be mingled with filtering more than most 10 μ m in the melt, export the chute cup when melt enters by second stage fine foam ceramic filter plate 10, the above inclusion of most 10 μ m is eliminated.Because 3 air supportings of preceding decontamination chamber and first step gross porosity foamed ceramic filter plate 9 have been removed size greater than the inclusion of 50 μ m substantially, second stage fine foam ceramic filter plate 10 can not stopped up by inclusion.
