[0001] The present application relates to the technical field of double-chamber melting furnace electromagnetic pump aluminum liquid pipeline cleaning, in particular to a double-chamber melting furnace electromagnetic pump aluminum liquid pipeline cleaning method, an aluminum projectile and a mold. BACKGROUND

[0002] Waste aluminum recycling is an important industry of energy-saving and re-production, and the main supporting facility of waste aluminum recycling is the electromagnetic pump pipe of double-chamber furnace waste aluminum remelting. However, the inner wall of the electromagnetic pump pipe is generally covered with slag during the waste aluminum remelting process.

[0003] The double-chamber melting furnace is mainly used for remelting waste materials to produce remelted water. Due to the high content of aluminum alloy and high viscosity, slag is easily formed, which leads to the problem of slag accumulation on the inner wall of the electromagnetic pump pipe.

[0004] The slag accumulation on the inner wall of the electromagnetic pump pipe will cause the aluminum liquid level in the charging well of the double-chamber melting furnace electromagnetic pump to be low, which leads to problems such as low aluminum liquid circulation rate in the furnace, slow heating, large burning loss, and slow aluminum output. Therefore, the double-chamber melting furnace needs to be stopped, and the accumulated slag adsorbed on the inner wall of the pump pipe needs to be manually dredged. The manual dredging of the accumulated slag is time-consuming, laborious, and costly, which not only affects the timely completion of the production task and increases the production cost, but also increases the labor intensity of the employees.

[0039] The slag accumulated on the inner wall of the electromagnetic pump pipe can cause the liquid level of the aluminum water in the charging well of the electromagnetic pump of the double-chamber melting furnace to be low, resulting in low liquid circulation rate of the aluminum water in the furnace, slow heating, large burning loss, slow aluminum output, etc. Therefore, the double-chamber melting furnace needs to be stopped, and the accumulated slag adsorbed on the inner wall of the pump pipe is manually dredged. The manual dredging of the accumulated slag is time-consuming, laborious, and increases the labor intensity of the employees.

[0040] In order to not affect the purity of the subsequent aluminum liquid, manual dredging generally uses tools such as shovels for physical cleaning, and cleaning agents cannot be used, which is very laborious and time-consuming.

[0041] Therefore, the design concept of the present application is to design a method to replace manual dredging without affecting the purity of the subsequent aluminum liquid, and to creatively use the electromagnetic pump itself to emit aluminum projectiles to the electromagnetic pump pipe to clean the accumulated slag on the inner wall of the electromagnetic pump pipe. The concept is very ingenious and easy to implement and promote. The aluminum projectiles hit the accumulated slag on the inner wall of the electromagnetic pump pipe and finally fall into the furnace to be melted, without affecting the purity of the subsequent aluminum liquid.

[0046] Step S4, start the electromagnetic pump and run it backward, adjust the power to 100%, use the reverse thrust of the electromagnetic pump to shoot the aluminum projectile 1 into the electromagnetic pump pipe 2, when passing through the electromagnetic pump pipe 2, the aluminum projectile 1 hits the accumulated slag 201 on the inner wall of the electromagnetic pump pipe 2, and finally the aluminum projectile 1 falls into the furnace;

[0047] Step S5, repeat the above steps S1 to S4 until the electromagnetic pump pipe 2 is clean.

[0050] Among them, the cross section of the shovel 103 is triangular; the design of the triangular structure is convenient for manufacturing, and the triangular structure is relatively sharp, which is beneficial to shovel off the accumulated slag 201 on the inner wall of the electromagnetic pump pipe 2.

[0051] Among them, the aluminum projectile 1 adopts a hollow structure; the design of the hollow structure is to melt the aluminum projectile quickly in the later stage, of course, the aluminum projectile 1 can also adopt a solid structure, the solid structure has larger mass and slightly better cleaning effect, the user can choose according to his own needs.
