Problems solved by technology

[0003] At present, most slag removal operations are performed through a single furnace for degassing, refining and slag removal operations, and finally manual slag removal operations. Although it can reduce burning losses, it has certain restrictions on the continuous and high-yield operation efficiency of aluminum alloy processing; and often Single furnace degassing and refining slag removal require the cooperation of multiple people, resulting in an increase in labor costs

Embodiment 1

[0023] like Figure 1-Figure 4 As shown, the automatic deslagging device of the smelting furnace includes a liquid storage tank 1, a first discharge channel 21, a slag removal furnace 3, a stirring mechanism 4, a second discharge channel 22 and a third discharge channel 23; The feed end of channel 21 communicates with the discharge end of liquid storage tank 1, and the discharge end of first discharge channel 21 communicates with the feed end of deslagging furnace 3; Mechanism 4 comprises a first stirring element 41, a second stirring element 42, a first bearing frame 43 and a gearbox 44, the first stirring element 41 comprises a first stirring shaft 411 and a first stirring blade 412, and the second stirring element 42 comprises a first stirring element 41. Two stirring shafts 421 and the second stirring blade 422, the second stirring shaft 421 is rotationally connected with the first bearing frame 43, the second stirring blade 422 is set on the outer wall of the second stirr...

Embodiment 2

[0029] like Figure 1-Figure 4 As shown, for the above embodiments, this embodiment optimizes the structure of the second discharge channel.

[0030] In the automatic deslagging device of the smelting furnace, a slope surface 221 is provided inside the end of the second discharge channel 22 close to the deslagging furnace 3 , and the height of the slope surface 221 gradually increases along the direction away from the inside of the slagging furnace 3 . By setting the slope surface 221, when the scum carries molten aluminum into the slope surface 221, due to the inclination angle of the slope surface, the molten aluminum will flow back into the deslagging furnace 3, reducing the consumption of aluminum in the process of slag removal and greatly saving Cost (during continuous operation, the temperature at the inner wall and side wall opening 31 of the deslagging furnace is relatively high, which provides high-temperature environment support for the reflow of molten aluminum).

Embodiment 3

[0032] like Figure 1-Figure 4 As shown, for the above embodiments, this embodiment optimizes the structure of the second stirring blade.

[0033] In this smelting furnace automatic deslagging device, the second stirring blade 422 includes a centrifugal blade 4221 and a concave plate 4222, and a plurality of centrifugal blades 4221 are arranged symmetrically on the outer wall of the second rotating shaft 421, and a concave plate is arranged on the top of the centrifugal blade 4221 4222, the concave surface of the concave plate 54 is arranged along the rotation direction of the centrifugal blade 4221. Centrifugal blade 4221 is beneficial to beat scum to the inner wall of slag removal furnace 3 through the centrifugal force generated by rotation, and setting concave plate 4222 can increase the amount of scum "collected" by second stirring blade 422 during the rotation process, and It can reduce excessive scum and leak from the top of the centrifugal blade 4221, improving the ef...

Abstract

The invention relates to the field of metal smelting preparation, in particular to an automatic deslagging device of a smelting furnace, which comprises a liquid storage tank, a first discharging channel, a deslagging furnace, a stirring mechanism, a second discharging channel and a third discharging channel; a stirring mechanism is arranged on the deslagging furnace and comprises a first stirring part, a second stirring part, a first bearing frame and a gearbox, the first stirring part comprises a first stirring shaft and a first stirring blade, the second stirring part comprises a second stirring shaft and a second stirring blade, and the second stirring shaft is rotatably connected with the first bearing frame; a side wall opening is arranged on the upper portion of the deslagging furnace, a feeding end of the third discharging channel is communicated with the bottom of the deslagging furnace, and a feeding end of the second discharging channel is communicated with the upper portion of the deslagging furnace through the side wall opening; and in the vertical direction, the upper portion of the second stirring blade is not lower than the lowest point of the side wall opening, and the lower portion of the second stirring blade is not higher than the lowest point of the side wall opening. Continuous and automatic refining and deslagging are realized, the labor intensity is reduced, and the operation efficiency is improved.

Description

technical field [0001] The invention relates to the field of metal smelting preparation, in particular to the structural technical field of an automatic slag removal device for a smelting furnace. Background technique [0002] In the aluminum alloy smelting process, after the aluminum ingots and aluminum ore are melted into a liquid at high temperature, it is necessary to refine, degas, and remove impurities and slag from the molten liquid. [0003] At present, most slag removal operations are performed through a single furnace for degassing, refining and slag removal operations, and finally manual slag removal operations. Although it can reduce burning losses, it has certain restrictions on the continuous and high-yield operation efficiency of aluminum alloy processing; and often Single furnace degassing and refining slag removal require the cooperation of multiple people, resulting in an increase in labor costs. Contents of the invention [0004] The purpose of the pres...
