Embodiment Construction
[0034] The present invention will be further described below in conjunction with the accompanying drawings: In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings. The descriptions thereof are only for explaining the present invention, not as limiting the present invention. The orientation adopted by the present invention is that the handle pipe section 5 stretches toward the inside of the furnace, the middle part of the telescopic slag suction tube 2 is inside, the two ends are outside, the inside of the filter residue filling body 8 is inside, and vice versa is outside.
[0035] Such as Figure 1-6 As shown, a suction pump type slag removal method for molten aluminum comprises steps:
[0036] Step 1. Set the L-shaped slag removal holder 1 as a tubular hollow structure. The L-type slag removal holder 1 inclu...

The invention discloses a suction pump-type slag removal method for aluminum liquid. The outer end of the handle pipe section is connected with a suction pump through a hose, so that the telescopic slag suction cylinder is in a contracted state, and the end of the telescopic slag suction cylinder will be provided. Stretch into the furnace hall, hold the pipe section on the lower side of the furnace door, extend the telescopic slag suction cylinder by operating the hand-operated two-way reel, start the air pump, and the worker holds the handle end of the L-shaped slag removal holder to make it The end of the telescopic slag suction cylinder floats on the liquid surface of the molten metal and moves back and forth, and the air pump sucks the scum on the surface of the aluminum liquid and the aluminum liquid from the telescopic slag suction cylinder through the L-shaped slag removal holder into the filter residue tank through suction. In the device, the scum and aluminum liquid are separated through the filter slag filling device. Through observation, whether the scum on the liquid surface is cleaned up, and no scum is found; The process triggers the valve opening device to open, so that the molten metal in the telescopic slag suction cylinder is completely released, and then the slag removal device is taken out to complete the slag removal.
Description
technical field [0001] The invention relates to the technical field of industrial furnaces and non-ferrous metal smelting equipment, in particular to a suction pump type slag removal method for molten aluminum. Background technique [0002] In the manufacture of industrial products, solid non-ferrous metal blocks, such as aluminum ingots, are usually melted into molten aluminum. After the molten aluminum is purified through slag removal, impurity removal or precipitation, the molten aluminum is cast into the corresponding In the grinding tool, it is condensed and cast into various products or intermediate products. [0003] Melting non-ferrous metal blocks into molten aluminum is carried out under high temperature conditions in large-scale smelting furnaces, because non-ferrous metal blocks that have not been smelted usually have low purity and contain more impurities. After the non-ferrous metal blocks are melted into aluminum After the liquid is melted, during the refinin...
