[0037] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with embodiments, but the scope of protection claimed in the utility model is not limited to the following specific embodiments.

[0038] Embodiment 1:

[0039] refer to Figure 1 and Figure 2 , an aluminum electrolytic cell anode feeding auxiliary device, including an electrolytic cell bottom shell 11, a main baffle 21 and a feed port baffle 31.

[0040] The main baffle 21 is detachably mounted on the bottom shell 11 of the electrolytic cell. A triangular support plate 22 is fixedly connected to one side of the main baffle 21. The triangular support plate 22 is clamped with the bottom shell 11 of the electrolytic cell. The upper end of the main baffle 21 is tilted toward the direction close to the triangular support plate 22. A transverse rib 23 is provided on one side of the main baffle 21 close to the triangular support plate 22. The transverse rib 23 is fixedly connected to the main baffle 21 and the triangular support plate 22, respectively. There are three triangular support plates 22, which are evenly distributed along the length direction of the main baffle 21. There are two transverse ribs 23, which are alternately distributed along the length direction of the main baffle 21. Both ends of the transverse rib 23 are fixedly connected to adjacent triangular support plates 22, respectively.

[0041] The main baffle 21 is fixedly mounted with a handle 24, which is located on one side of the main baffle 21 close to the triangular support plate 22. The arrangement of the handle 24 facilitates the removal of the main baffle 21 from the bottom shell 11 of the electrolytic cell. The handle 24 and the transverse ribs 23 are staggered along the width direction of the main baffle 21, and the handle 24 includes a bending section 25 and two connecting sections 26, the bending section 25 is located between the two connecting sections 26, the connecting section 26 is fixedly connected to the main baffle 21, the bending section 25 is bent in a direction away from the main baffle 21, and the two connecting sections 26 are arranged along the length direction of the main baffle 21. There are two handles 24 in total, and the three triangular support plates 22 and the two handles 24 are alternately distributed along the length direction of the main baffle 21.

[0042] The transverse ribs 23 extend along the length direction of the main baffle 21, and the side edges of the transverse ribs 23 are fixedly connected to the main baffle 21. The electrolytic cell bottom shell 11 is fixedly connected with the longitudinal partition 12, and the main baffle 21 is provided with a positioning groove 27 for the longitudinal partition 12 to be inserted, and the main baffle 21 is clamped with the longitudinal partition 12.

[0043] The feed port baffle 31 is fixedly connected with a handle 32, which is detachably mounted on the bottom shell 11 of the electrolytic cell. A positioning plate 33 is provided at the tail of the handle 32, which is fixedly connected with the handle 32 and is clamped with the bottom shell 11 of the electrolytic cell. The positioning plate 33 is clamped with the bottom shell 11 of the electrolytic cell to prevent the handle 32 from accidentally moving in the axial direction. The feed port baffle 31 is provided with a material block 34. A covering material 5-10 cm thick is piled on one side of the feed port baffle 31 away from the feed port, and the covering material is poured with a liquid electrolyte to make the covering bonded to form a material block 34.

[0044] When in use, the main baffle 21 is placed 10 cm away from the outside of the anode, and the covering material is added between the anode and the main baffle 21. The covering material is blocked by the main baffle 21 to prevent the covering material from rolling away from the anode, so as to ensure that the covering material can cover the anode. The handle 32 provides support to the discharge port baffle 31, so that the covering material at the discharge port can be blocked by the discharge port baffle 31, which plays a role in reducing the material entering the discharge port. A large amount of heat is generated during the electrolytic aluminum production process, so that the covering material composed of a mixture of alumina and cryolite at the main baffle 21 and the discharge port baffle 31 is fixed in a high temperature environment, and then the main baffle 21 is removed from the bottom shell 11 of the electrolytic cell. After the main baffle 21 is removed, the covering material formed into a fixed shape can still cover the anode.

[0045] This embodiment has the following advantages:

[0046] By blocking the covering material through the main baffle 21 and the discharge port baffle 31, it can be effectively ensured that the covering material keeps covering the anode, and the discharge port baffle 31 can block the covering material entering the discharge port, thereby preventing the discharge port from being blocked, thereby achieving the advantage of a better blocking effect on the covering material.

[0047] After the covering material is formed into a fixed shape, the main baffle 21 and the discharge port baffle 31 are removed. This can prevent the materials of the main baffle 21 and the discharge port baffle 31 from causing adverse effects on the electrolytic aluminum production, and can also protect the main baffle 21 and the discharge port baffle 31, thereby increasing their service life.

[0048] The triangular support plate 22 and the handle 32 provide support force to the main baffle 21 and the discharge port baffle 31 respectively, so that the main baffle 21 and the discharge port baffle 31 can remain stable and ensure that the main baffle 21 and the discharge port baffle 31 can keep blocking the covering material.

[0049] By setting the material block 34, after the discharge port baffle 31 is removed, the covering material can be blocked by the material block 34, further preventing the covering material from rolling into the discharge port, thereby preventing the discharge port from being blocked, and achieving the advantage of a better blocking effect on the covering material.

[0050] The transverse ribs 23 can provide a supporting force between the triangular support plate 22 and the main baffle plate 21 , thereby improving the structural stability of the triangular support plate 22 and the main baffle plate 21 .

[0051] The three triangular support plates 22 support the main baffle plate 21 at different positions in the length direction of the main baffle plate 21 , thereby improving the stability of the main baffle plate 21 and enabling the main baffle plate 21 to block the covering material.

[0052] The transverse ribs 23 and the triangular support plates 22 are alternately distributed, so that the support force of the transverse ribs 23 and the triangular support plates 22 on the main baffle 21 is more uniform, thereby improving the structural stability of the main baffle 21.

[0053] The bending section 25 is bent and arched in a direction away from the main baffle 21, so that it is convenient to apply force on the bending section 25 and pull the connecting section 26 and the main baffle 21, which plays a role in facilitating the removal of the main baffle 21 through the handle 24. The two connecting sections 26 are arranged along the length direction of the main baffle 21, so that the two connecting sections 26 can be connected by the bending section 25, and the two connecting sections 26 are respectively connected to different positions of the main baffle 21, and then the bending section 25 and the two connecting sections 26 can provide support force to the main baffle 21 at different positions, which plays a role in increasing the structural strength of the main baffle 21 and further improving the structural stability of the main baffle 21.

[0054] The two handles 24 and the three triangular support plates 22 are alternately distributed, and the main baffle 21 can be supported at different positions by the handles 24 and the triangular support plates 22 , thereby enhancing the structural strength of the main baffle 21 .

[0055] The length direction of the transverse rib 23 is the same as that of the main baffle 21, so that the transverse rib 23 and the main baffle 21 can obtain a larger connection length, thereby improving the stability of the connection structure between the transverse rib 23 and the main baffle 21. At the same time, the transverse rib 23 can provide support force to the main baffle 21 at different positions along the length direction of the main baffle 21, thereby improving the reliability of the main baffle 21.

[0056] The longitudinal partition 12 can improve the structural strength of the bottom shell 11 of the electrolytic cell, and can also separate the surface of the bottom shell 11 of the electrolytic cell, so as to facilitate the installation of electrodes on the bottom shell 11 of the electrolytic cell. The longitudinal partition 12 is inserted into the positioning groove 27, so that the main baffle 21 can be positioned by the longitudinal partition 12, and the longitudinal partition 12 can also provide support for the main baffle 21.

[0057] Embodiment 2:

[0058] refer to Figure 3 and Figure 4 , an auxiliary device for feeding anodes of aluminum electrolysis cells, which differs from Example 1 in that:

[0059] A clamping plate 41 and a clamping block 42 are provided on one side of the main baffle 21 away from the triangular support plate 22, and a clamping groove 43 for the handle 32 to be clamped is provided between the clamping plate 41 and the clamping block 42. An arc surface 44 is provided on one side of the clamping block 42 away from the main baffle 21, and the arc center of the arc surface 44 is located at one end of the bottom edge of the triangular support plate 22 away from the main baffle 21. An arc edge 45 is provided on one edge of the clamping plate 41 away from the main baffle 21, and the arc center of the arc edge 45 is located at one end of the bottom edge of the triangular support plate 22 away from the main baffle 21.

[0060] This embodiment has the following advantages:

[0061] The handle 32 is inserted into the slot 43 to position and support the handle 32 , so that the handle 32 and the feed port baffle can be positioned through the main baffle 21 .

[0062] The arc center of the arc surface 44 and the arc edge 45 is located at the end of the bottom edge of the triangular support plate 22 away from the main baffle 21, so that in the process of removing the main baffle 21 and the discharge port baffle 31, the handle 24 can be pushed to drive the main baffle 21 to rotate around the end of the bottom edge of the triangular support plate 22 away from the main baffle 21, so as to facilitate the removal of the main baffle 21, the block 42 and the card 41 from the covering material formed into a fixed shape, and prevent the covering material from being adhered to the main baffle 21, the block 42 and the card 41 and unable to be removed. In addition, during the rotation of the card 41, the handle 32 and the discharge port baffle 31 can be pushed to move, which plays a role in facilitating the removal of the discharge port baffle 31.
