Description

Technical Field

[0001] The utility model relates to the technical field of aluminum liquid degassing and slag removal, in particular to an aluminum liquid degassing and slag removal device. Background Art

[0002] A large amount of hydrogen will dissolve in the aluminum liquid during the smelting process. When the aluminum liquid cools and solidifies, the dissolved hydrogen may remain inside the solidified aluminum block in the form of bubbles, forming so-called "pores" or "inclusions", which will seriously affect the density and strength of the casting, destroy the continuity of the material, and cause stress concentration and cracks.

[0003] Before casting aluminum liquid, degassing and slag removal are required to ensure the quality of castings. However, the current degassing and slag removal devices can only perform one-time slag removal when in use. The slag needs to be processed after filtering out. Otherwise, when the slag is removed again, the filtered slag may be mixed with the aluminum liquid again, thereby affecting the slag removal effect. For this reason, we provide a molten aluminum degassing and slag removal device. Utility Model Content

[0013] Beneficial effects:

[0014] 1.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] First embodiment

[0024] As shown in the attached Figure 1 and the attached Figure 2 As shown: An aluminum liquid degassing and slag removal device includes a holding cylinder 1 and a sealing cover 2 provided above the holding cylinder 1, and includes: an air extraction assembly 3, which is arranged outside the holding cylinder 1 and is used for sucking the gas inside the holding cylinder 1. The air extraction assembly 3 includes a pump body 301 installed on the outer surface of the holding cylinder 1. The input end of the pump body 301 is fixedly connected to an air extraction pipe 302. The input end of the air extraction pipe 302 penetrates through the holding cylinder 1 and extends into the holding cylinder 1. The output end of the pump body 301 is fixedly connected to an air delivery pipe 303. When the pump body 301 works, the air extraction pipe 302 will suck the gas discharged from the aluminum liquid inside the holding cylinder 1, so as to achieve the effect of exhausting the aluminum liquid.

[0025] Second embodiment

[0026] As shown in Figure 2 and Figure 3As shown, the exhaust slag removal assembly 4 is arranged inside the sealing cover 2 and extends to the bottom of the holding cylinder 1. It includes a motor 401 installed on the inner top wall of the sealing cover 2, a rotating rod 402 arranged on the output shaft of the motor 401. A support rod 403 is fixedly connected to the outer surface of the rotating rod 402, a group of stirring rods 404 are fixedly connected to the outer surface of the support rod 403, and a slag collection structure is arranged outside the rotating rod 402. The slag collection structure of the exhaust slag removal assembly 4 includes a filter frame 405 arranged outside the rotating rod 402 and a suspension plate 406 fixedly connected to the outer surface of the rotating rod 402. A motor 407 is installed on the bottom surface of the suspension plate 406. The output end of the motor 407 is fixedly connected to a threaded cylinder 408. The inner wall of the threaded cylinder 408 is threadedly connected to a threaded rod 409. The bottom end of the threaded rod 409 is connected to the upper surface of the filter frame 405. When the motor 407 works, it can push the filter frame 405 to descend. The bottom end of the filter frame 405 will move down into the molten aluminum, and its top end is above the molten aluminum. When the motor 401 works, the filter frame 405 will rotate to collect the slag in the molten aluminum. After the filter frame 405 collects the slag in the molten aluminum, let the motor 407 reverse, and the filter frame 405 will rise, and the slag will remain inside the filter frame 405, preventing the collected slag from mixing with the molten aluminum again.

[0027] Furthermore, to ensure the stable lifting and lowering of the filter frame 405, as Figure 3 shown, a stabilizing rod 410 is slidably connected to the upper surface of the suspension plate 406. The bottom end of the stabilizing rod 410 is connected to the upper surface of the filter frame 405. By using the sliding connection between the stabilizing rod 410 and the suspension plate 406, the filter frame 405 can be stabilized, thus ensuring the smooth lifting and lowering of the filter frame 405.

[0028] Furthermore, to prevent the filter frame 405 from falling into the molten aluminum, as Figure 3 shown, a baffle 411 is arranged above the suspension plate 406. The bottom surface of the baffle 411 is connected to the top end of the stabilizing rod 410. By using the baffle 411, the descending height of the stabilizing rod 410 can be limited, so that the threaded rod 409 is located inside the threaded cylinder 408, thereby preventing the filter frame 405 from falling off.

[0029] Furthermore, to ensure the stability of the rotating rod 402, as Figure 2 and Figure 3 shown, the exhaust slag removal assembly 4 further includes a stabilizing cylinder 412 fixedly connected to the inner bottom wall of the holding cylinder 1. The bottom end of the rotating rod 402 extends into the stabilizing cylinder 412 and is slidably connected to the inner wall of the stabilizing cylinder 412. The bottom end of the rotating rod 402 is inserted into the stabilizing cylinder 412, forming the stability of the bottom of the rotating rod 402 and preventing the rotating rod 402 from shaking and deviating.

[0030] Third Embodiment

[0031] AsFigure 1 and Figure 4 As shown in Figure 4 , the sealing assembly 5 includes an annular groove 501 formed on the upper surface of the top of the containing cylinder 1 and an annular sealing plate 502 located inside the annular groove 501. The upper surface of the annular sealing plate 502 is connected to the bottom surface of the sealing cover 2. By connecting the annular sealing plate 502 with the annular groove 501, the connection between the sealing cover 2 and the containing cylinder 1 can be sealed to prevent gas from entering the containing cylinder 1 and mixing with the molten aluminum.

[0032] Furthermore, in order to ensure the stability of degassing and slag removal of the molten aluminum, as Figure 1 and Figure 4 shown, the sealing assembly 5 further includes annular connecting plates 503 installed on the outer surface of the containing cylinder 1 and the outer surface of the sealing cover 2. The two annular connecting plates 503 are connected by a set of bolts 504. By connecting the annular connecting plates 503 with the bolts 504, the connection between the sealing cover 2 and the containing cylinder 1 can be formed, thus ensuring the smooth progress of the degassing and slag removal work.

[0033] Working principle: During use, first pour the molten aluminum into the containing cylinder 1, then insert the annular sealing plate 502 on the sealing cover 2 into the annular groove 501, and then connect the annular connecting plates 503 with the bolts 504. Then start the motor 407 to work. The motor 407 will drive the threaded cylinder 408 to rotate outside the threaded rod 409, and the threaded rod 409 will gradually move downward and push the bottom of the filter frame 405 into the molten aluminum. Then start the motor 401 and the pump body 301 to work. The motor 401 will drive the support rod 403 and the hanging plate 406 to rotate through the rotating rod 402. The support rod 403 will drive the stirring rod 404 to stir and exhaust the molten aluminum. The pump body 301 will suck the gas inside the containing cylinder 1 through the suction pipe 302. At the same time, the hanging plate 406 will drive the filter frame 405 to rotate on the surface of the molten aluminum, and the filter frame 405 will collect the slag in the molten aluminum. After the collection is completed, just start the motor 407 to reverse, and the filter frame 405 will rise and separate from the molten aluminum. The filtered slag will remain inside the filter frame 405, thus ensuring the slag removal effect.
