Description

Technical Field

[0001] This utility model belongs to the field of electrolytic aluminum production technology, specifically referring to an electrolytic aluminum slag removal device. Background Technology

[0002] Carbon slag from aluminum electrolytic cells is a hazardous waste generated during the aluminum smelting process. During continuous production in the electrolytic cell, the carbon content in the electrolyte increases as the carbon anode is continuously consumed. When the carbon slag content in the electrolyte reaches a certain concentration, it not only increases the specific resistance of the electrolyte but can also cause the anode to become damaged, affecting the main economic indicators of the electrolytic cell. Therefore, carbon slag is harmful to electrolytic production, and thus, the removal of carbon slag has become a routine operation in electrolytic production.

[0003] In existing technologies, the scum in the electrolytic cell is not in a uniform and loose state. Affected by fluctuations in electrolysis temperature and the anode effect, it is easy to form agglomerated scum, sticky scum, and unevenly layered scum. Existing devices do not have any pre-intervention measures and directly remove the scum, which affects the scum removal efficiency. Secondly, the equipment was not preheated to adapt to high temperatures before starting. The slag removal head, which was at room temperature, was suddenly inserted into the high-temperature electrolyte, which caused cracks due to thermal shock and shortened its service life. Utility Model Content

[0004] The technical problem this invention aims to solve is that the electrolytic aluminum slag removal device lacks the function of processing slag blocks, making it easy to fail to remove slag completely, and the slag removal head lacks pre-treatment operations.

The horizontal adjustment slide is threadedly connected to the threaded rod through a slide bracket.

[0007] Furthermore, a slide body is fixedly connected to the upper part of the equipment base, the lifting equipment frame is slidably arranged on the slide body, and an electric push rod 2 passes through the side wall of the slide body, the output end of the electric push rod 2 is fixedly connected to the side wall of the lifting equipment frame.

[0008] Furthermore, the upper part of the equipment base is provided with two sets of L-shaped frames arranged in a mirror image, and a preheating air outlet shell is fixed between the two sets of L-shaped frames. An electric heating module is provided on the outer wall of the preheating air outlet shell, and a fan body passes through the preheating air outlet shell.

[0009] Furthermore, an insulation sleeve is fixedly connected to the lower part of the L-shaped frame, and the upper part of the insulation sleeve is provided with an opening that communicates with the lower part of the preheating air outlet casing.

[0015] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively. Example 1

[0016] like Figure 1 , Figure 3 As shown, the present invention proposes an electrolytic aluminum slag removal device, including a base 1, a horizontal adjusting slide 11 above the base 1, a connecting frame 12 slidably mounted on the horizontal adjusting slide 11, an electric push rod 121 for driving the connecting frame 12 to move fixedly on the inner side of the horizontal adjusting slide 11, a connecting platform 13 fixedly mounted at the bottom of the connecting frame 12, a slag removal head body 14 fixedly mounted at the lower part of the connecting platform 13, and a slag removal auxiliary unit. The slag removal auxiliary unit includes a conduit mounting sleeve 2 fixedly mounted on the front side of the connecting platform 13, an ultrasonic generator 21 mounted on the upper part of the conduit mounting sleeve 2, a transducer 22 fixedly mounted at the lower part of the conduit mounting sleeve 2, the ultrasonic generator 21 and the transducer 22 being electrically connected, and an energy storage module 23 mounted on the ultrasonic generator 21.

[0017] The connecting frame 12 is moved on the horizontal adjusting slide 11 by the connecting platform 13 to adjust the position of the slag removal head body 14. Before the slag removal operation, the transducer 22 is located in front of the slag removal head body 14 and contacts the slag block. The ultrasonic generator 21 works and the transducer 22 converts the electrical signal into high frequency vibration to peel off the slag block and assist the slag removal operation. The line between the transducer 22 and the ultrasonic generator 21 passes through the conduit installation sleeve 2.

[0018] like Figure 2 As shown, a lifting equipment frame 3 is provided above the equipment base 1. A limiting groove 31 is opened on the inner side of the lifting equipment frame 3. A motor 32 passes through the upper part of the lifting equipment frame 3. A threaded rod 33 set in the limiting groove 31 is fixedly connected to the output shaft of the motor 32. The horizontal adjustment slide 11 is threadedly connected to the threaded rod 33 through a slide bracket. The motor 32 drives the threaded rod 33 to rotate, and the height of the horizontal adjustment slide 11 is adjusted through the slide bracket. Example 2

[0019] like Figure 2 As shown, a slide body 4 is fixedly connected to the upper part of the equipment base 1, and the lifting equipment frame 3 is slidably arranged on the slide body 4. An electric push rod 41 is passed through the side wall of the slide body 4, and the output end of the electric push rod 41 is fixedly connected to the side wall of the lifting equipment frame 3.

[0020] When in use, the electric push rod 41 works, the output end extends, and pushes the lifting equipment frame 3 to slide and adjust its position on the slide body 4.

[0021] like Figure 1 , 4 As shown, the equipment base 1 is supported by two sets of mirror-arranged L-shaped frames 5. A preheating air outlet housing 51 is fixed between the two sets of L-shaped frames 5. An electric heating module 52 is provided on the outer wall of the preheating air outlet housing 51. A fan body 53 passes through the preheating air outlet housing 51. An insulation sleeve 6 is fixed to the lower part of the L-shaped frame 5.

Grooves 62 that can be passed through by the connecting platform 13 are provided on both sides of the opening 61.

[0022] It should be noted that when the slide body 4 is pushed to the front end on the lifting equipment frame 3 and the connecting frame 12 moves to the front end inside the horizontal adjustment slide body 11, the slag head body 14 is located below the preheating air outlet housing 51. The electric heating module 52 is powered on and heated. Through the operation of the fan body 53, hot air is blown out from below the preheating air outlet housing 51 to preheat the slag head body 14, so as to avoid cracking caused by thermal shock when directly entering the electrolysis cell. The heat insulation sleeve 6 plays the role of heat insulation and heating. The connecting platform 13 can pass through the groove 62 from below and send the slag head body 14 into the heat insulation sleeve 6.

[0023] The slag-collecting head body 14 is provided with slag-collecting teeth 7, and a heat-conducting layer is welded on the slag-collecting teeth 7.

[0024] The heat-conducting layer utilizes high thermal conductivity to quickly conduct local heat. The slag-removing tooth 7 is the first part to come into contact with the slag layer during slag removal. Rapid heating can ensure that its temperature reaches the standard first, avoiding thermal shock caused by insufficient local temperature.

[0025] The above is the entire usage process of an electrolytic aluminum slag removal device.

[0026] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto.
