Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic aluminum, in particular to an electrolytic aluminum preheating anode conveying device. Background Art

[0002] In the prior art, when using carbon prebaked anodes for electrolytic aluminum production, the anodes will be continuously consumed as the electrochemical reaction proceeds, and therefore need to be replaced regularly. When replacing the anodes, the brittleness of the material can cause serious thermal shock problems, and the anodes need to absorb a large amount of heat when entering the cell at room temperature, which greatly interferes with the normal operation of the electrolytic cell. At present, the preheating anode process is often used to heat the anodes in a preheating furnace before transporting them to the electrolytic cell for use. However, the preheating anodes lack heat insulation measures during transportation, resulting in a large amount of heat dissipation into the workshop, which not only affects the entry temperature of the preheating anodes into the cell, but also increases the temperature in the electrolytic workshop, affecting the working environment.

[0003] The patent document with publication number CN207632092U discloses a preheating anode conveying device for electrolytic aluminum, which can keep the preheating anode warm during the conveying process by setting an isolation cover. However, the solution of the document still has the following aspects to be improved:

[0004] 1. In order to facilitate the grabbing of the isolation cover, the upper part of the isolation cover needs to be open, and the thermal insulation of this open structure is limited;

[0005] 2. In order to facilitate the isolation cover to move down to cover the preheating anode, the lower part of the isolation cover needs to be open. The thermal insulation of this open structure is limited and the thermal insulation effect needs to be improved. Utility Model Content

[0039] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0040] See also Figure 1~Figure 4 This embodiment provides an electrolytic aluminum preheating anode conveying device, including a suspension arm 1, a grabbing mechanism, a sliding member 3 and a splicing cover 4.

[0041] The boom 1 is used to connect with overhead crane and other handling equipment in the workshop.

[0042] The grabbing mechanism is installed at the lower end of the boom 1 and is used to grab the connecting rod of the preheated anode so as to facilitate the transportation of the preheated anode. In a specific implementation scenario, the grabbing mechanism includes a pneumatic clamp 2.

[0043] The sliding member 3 is connected to the boom 1 in a longitudinal sliding manner, and the sliding member 3 is located above the grabbing mechanism.

[0044] In a specific implementation scenario, the sliding member 3 is longitudinally slidably connected to the boom 1 in the following manner: the sliding member 3 is slidably sleeved on the boom 1 .

[0045] The splicing cover body 4 is located below the gripping mechanism and is connected to the sliding member 3 through a connecting assembly. The splicing cover body 4 can move in the horizontal direction. There are multiple splicing cover bodies 4, and the multiple splicing cover bodies 4 are distributed around the preheating anode, and each splicing cover body 4 can be gathered together to form a relatively closed insulating space 5 for accommodating the preheating anode, wherein the side, top and bottom of the insulating space 5 are all closed.

[0046] In a specific implementation scenario, there are two spliced ​​cover bodies 4.

[0047] When in use, the boom 1 is connected to a handling device such as an overhead crane, and the overhead crane is used to drive the electrolytic aluminum preheating anode conveying device to move; in the process of the boom 1 moving down to allow the spliced ​​cover 4 to enter the preheating furnace, the spliced ​​cover 4 will first contact the furnace bottom 7 of the preheating furnace to keep the spliced ​​cover 4 and the sliding member 3 in the current position, and then the boom 1 and the grabbing mechanism continue to move down, and the grabbing mechanism grabs the connecting rod of the preheating anode, and then the boom 1 and the grabbing mechanism drive the preheating anode to move up, so that the bottom of the preheating anode is located above the inner side of the bottom of the splicing cover 4, and then the splicing covers 4 are gathered together to form a relatively closed insulation space 5 for accommodating the preheating anode, and the side, top and bottom of the insulation space 5 are all closed, so that in the subsequent transportation process, a better insulation environment can be provided for the preheating anode. It can be seen that compared with the prior art, the thermal insulation of this embodiment is better, and the improvement scheme of this embodiment does not require much adjustment to the prior art, and the cost of improvement is low.

[0048] In a specific implementation scenario, the connection assembly includes a cross rail 61, a slider 62 and a connecting rod 63. The cross rail 61 is fixed on the sliding member 3; the slider 62 is slidably connected to the cross rail 61; one end of the connecting rod 63 is connected to the slider 62, and the other end is connected to the splicing cover 4. In a specific implementation scenario, the slider 62 is an electric slider 62.

[0049] The slider 62 can drive the spliced ​​cover 4 to move in the horizontal direction through the connecting rod 63; through the arrangement of the cross rail 61, the slider 62 and the connecting rod 63, it is convenient to realize the mutual gathering or separation of the spliced ​​covers 4.

[0050] In addition, in order to improve the transport efficiency, the above-mentioned insulation space 5 can accommodate multiple preheating anodes at the same time, and Figure 4 As shown, one pneumatic gripper 2 can grab the connecting rods of multiple preheating anodes. In other embodiments, there may be multiple pneumatic grippers 2 to facilitate grabbing multiple preheating anodes.
