Problems solved by technology

However, due to the limited fluidity of inclusions in the metal melt, the upper inclusions in the settling chamber cannot completely settle to the bottom of the settling chamber in a short time, which increases the settling time and affects the purification effect of the metal melt.

Embodiment 1

[0023] Embodiment one, see figure 1 and figure 2 , the single-stage purification device for molten metal shown includes a housing 1 and a partition 2, the partition 2 is placed vertically in the housing 1 and separates the housing 1 into a filter chamber and a settling chamber, the The clapboard 2 is provided with a plurality of collecting holes connecting the filter chamber and the settling chamber, the settling chamber is provided with a settling mechanism, the side wall of the settling chamber is provided with a metal melt inlet 3; the above filter chamber is provided with a metal melt The outlet 4 is provided with a first filter plate 8 in the filter chamber, and the first filter plate is fixed between the molten metal outlet 4 and the highest collecting hole. The top of the shell 1 is provided with an upper slag discharge port 12, which is located at the upper right of the settling mechanism, and the upper slag discharge port is used to scoop out floating inclusions wit...

Embodiment 2

[0027] Embodiment two, see image 3 and Figure 4 , the shown two-stage purification device for molten metal, by analogy with the device in Embodiment 1, the first stage composed of the filter chamber, the settling chamber and the inclusion collection chamber is sequentially arranged in the housing 1 The purification part and the second-level purification part, the first filter plate 8 of the first-level purification part is fixedly connected with the lowermost inclined plate 9 of the second-level purification part through a connecting plate 11, ensuring that the The metal melt in the drainage pipe 5 is all filtered by the first filter plate 8 of the first-stage purification part, and then enters the second-stage purification part. Through multiple sedimentation and filtration, the purification effect of the metal melt is further improved.

[0028]During specific work, the metal melt enters the housing 1 from the metal melt inlet 3, and then enters the second-stage purificat...

Abstract

The invention discloses a metal melt purifying device. The metal melt purifying device comprises a shell and a partition plate; the partition plate is vertically arranged inside the shell and is used for dividing the shell into a filtration chamber and a deposition chamber; the partition plate is provided with a plurality of flow connecting holes communicating with the filtration chamber and the deposition chamber; a depositing mechanism is arranged inside the deposition chamber; the sidewall of the deposition chamber is provided with a metal melt inlet; the upper portion of the filtration chamber is provided with a metal melt outlet; a first filter plate is arranged inside the filtration chamber and is fixedly arranged between the metal melt outlet and the highest flow connecting hole; an inclusion collecting chamber is arranged below the deposition chamber; and the bottom of the inclusion collecting chamber is provided with a flow and dreg discharging hole. The metal melt purifying device can shorten the deposition time of the metal melt, improve the purification effect of the metal melt and realize continuous and smooth filtration of the metal melt.

Description

technical field [0001] The invention relates to the field of metal smelting, in particular to a purification device for metal melt. Background technique [0002] With the development of science and technology and industrial production, metals such as magnesium and aluminum and their alloys are widely used. However, the chemical properties of these metal alloys are very active, and they are easily oxidized in the process of smelting, casting, alloying, etc., forming metal inclusions or non-metal inclusions, which makes the alloys suffer from mechanical properties, casting properties, corrosion resistance, etc. Serious impact. Inclusions are the main impurities that endanger the quality and performance of alloys, so removing as many inclusions as possible is one of the main goals of metal melt purification. [0003] At present, for inclusions in molten metals such as magnesium and aluminum, common purification methods include flux purification, air blowing purification, filt...
