AI Technical Summary

Problems solved by technology

The following problems generally exist: the purification gas and flux cannot be uniformly supplied at the same time during the working process; the flux is easy to block in the pipeline; the dosage of flux is unstable and the quantification is not accurate, etc., so that the casting cannot achieve the expected purification treatment effect
The existence of these problems greatly limits the purification effect of gas and flux, which is not conducive to obtaining high-quality molten aluminum

Embodiment Construction

[0016] Provide the best embodiment of the present invention below in conjunction with accompanying drawing:

[0017] The upper port of the hopper 1 has a top cover 2 which acts as a seal, and a safety valve 14 is installed in the center of the top cover 2 . The hopper 1 is fixed above the feeder 3 and communicates with the feeder 3 . The outlet of the feeder 3 is connected to the mixer 4, the side of the mixer 4 has an air inlet 17, the rotating speed of the rotor 6 is controlled by the rotor frequency conversion motor 5, and the rotor 6 is fixed on the rotor rotating shaft by a rotor holder 9, The rotor rotating shaft 7 is installed on a machine base cast with aluminum alloy, and is supported by upper and lower two self-aligning bearings. The rotor rotating shaft and the rotor are connected by the upper fixing sleeve 11 of the rotor holder, the locking screw sleeve 13 and two semicircular hoops 12 .

Abstract

An apparatus for cleaning the liquid-state Al-alloy is composed of rotor and its lift mechanism, flux feeder, mixed, rotary jointer, feeding hopper with sealing top cover, and safety valve in the center of sealing top cover. Its advantages are not blocking the pipeline and high feed precision of flux.

Description

technical field [0001] The invention belongs to the field of purification treatment of metal materials, and in particular relates to equipment for purification treatment of liquid aluminum alloys. Background technique [0002] At present, the aluminum melt purification equipment produced at home and abroad is composed of a hopper, a feeding tee, and a pipeline. Depending on the gas pressure, the powder flux in the container is pressed into the liquid aluminum liquid through the pipeline to achieve the purpose of purification. For example: Shandong Aluminum Co., Ltd., Xi'an Aircraft Industry Co., Ltd., Second Automobile Dongfeng Precision Casting Co., Ltd., etc. The following problems generally exist: the purification gas and flux cannot be uniformly supplied at the same time during the working process; the flux is easy to block in the pipeline; the dosage of flux is unstable and the quantification is not accurate, etc., so that the castings cannot achieve the expected purifi...
