Description

TECHNICAL FIELD

[0001] The utility model belongs to aluminum anode technical field, specifically related to a device that can reduce aluminum anode consumption. BACKGROUND

[0002] Aluminum anode consumption is a large cost component in aluminum electrolysis cost except for alumina and power, and the current domestic anode gross consumption advanced level is about 450kg / T. AL. The current domestic anode gross consumption potential is deeply excavated, and the space is not big. But the anode net consumption reduction space is still big. In the electrolytic production process, the anode carbon block part on the electrolyte surface is seriously oxidized due to high temperature, causing the anode net consumption to be large. In the electrode reaction process, the reaction of C+O2=CO+CO2 consumes a large number of anodes.

[0003] Therefore, a device capable of reducing anode consumption is urgently needed. UTILITY MODEL CONTENT

[0004] In order to provide a device capable of reducing anode consumption, the utility model takes the following technical scheme:

[0005] A device capable of reducing aluminum anode consumption, comprising:

[0006] A carbon plate covering at least one surface of the carbon anode;

[0007] A high-conductivity graphite adhesive layer is arranged between the carbon plate and the carbon anode;

[0008] A plurality of carbon surface bolts, the carbon surface bolts sequentially pass through the carbon plate, the high-conductivity graphite adhesive layer, and cooperate with the threaded holes on the carbon anode to fix the carbon plate on the carbon anode.

[0009] Further, the carbon plate covers 2 side main surfaces of the carbon anode, or covers 2 side main surfaces and 2 end main surfaces, or covers the bottom palm of the carbon anode, or covers the upper terrace part of the carbon anode.

[0010] Further, the carbon plate is fitted to cover the carbon anode.

[0011] Further, the carbon plate is a sheet structure fitted to the surface shape of the carbon anode.

[0012] Further, the thickness of the carbon plate is 10mm-50mm.

[0013] Further, the thickness of the carbon plate is 10mm-15mm.

[0014] Further, the covered surface shape of the carbon anode is a plane or an arc surface.

[0015] Advantages:

[0016] The device capable of reducing consumption of aluminum anodes provided by the utility model reduces consumption by insulating air from the surface of anodes with cathode carbon blocks.

[0017] In addition, low-value carbon materials, especially waste cathode carbon blocks, are used to insulate air from the surface of anodes to reduce oxidation, and through an electrochemical reaction process, the current density of the low-value carbon materials is increased to promote the low-value carbon materials to participate in anode chemical reactions, thereby reducing carbon anode electrochemical reaction consumption.

[0021] Embodiment 1

[0022] Reference Figures 1-2 A device capable of reducing consumption of aluminum anodes includes:

[0023] A carbon plate 2 covers at least one surface of a carbon anode 1.

[0024] A high-conductivity graphite adhesive layer 4 is arranged between the carbon plate 2 and the carbon anode 1.

[0025] A plurality of carbon surface bolts 3 are sequentially threaded through the carbon plate 2, the high-conductivity graphite adhesive layer 4, and threaded holes on the carbon anode 1 to fix the carbon plate 2 on the carbon anode 1.

[0026] In this embodiment, the carbon plate 2 covers two side main surfaces of the carbon anode 1, or covers two side main surfaces and two end main surfaces, or covers the bottom of the carbon anode 1, or covers the upper part of the carbon anode 1.

[0027] In this embodiment, the carbon plate 2 is fitted to cover the carbon anode 1.

[0028] In this embodiment, the carbon plate 2 is a sheet structure that fits the surface shape of the carbon anode 1.

[0029] In the figure, the thickness of the carbon plate 2 is 10 mm-50 mm, and preferably 10 mm-15 mm.

[0030] In the embodiment, the covering surface shape of the carbon anode 1 is a plane or an arc surface.

[0031] Specifically, the low-value waste carbon material is processed into a sheet shape to fit the surface shape of the anode, and then is bonded. The sheet shape is restored to a thickness of 10mm-50mm, and a typical value is 10mm-15mm. Depending on whether the carbon anode covering surface is a plane or an arc, the bonding material is a high-conductivity adhesive. After bonding, a hole is drilled, a screw is tapped, and a carbon surface bolt is screwed on at the composite of the waste anode carbon material and the anode carbon block.

[0032] The carbon bolt is screwed in after being bonded with the conductive adhesive, and the carbon surface bolt is processed using high static pressure graphite carbon material.

[0033] The device provided in the embodiment can reduce the consumption of the anode for aluminum. A low-value carbon material is processed to fit the covering layer material on the surface of the anode for aluminum, and is bonded to the surface of the anode by high-conductivity bonding adhesive. Then, a high-strength graphite bolt is used for fastening, so as to isolate the anode oxidation loss caused by air in the anode consumption process.

[0034] In addition, during the electrochemical reaction process, the current density of the low-value carbon material is increased, the low-value carbon material is promoted to participate in the anode chemical reaction, the original carbon anode reaction is reduced, and thus the electrochemical reaction consumption of the carbon anode is reduced.

[0035] Embodiment 2

[0036] The embodiment is based on the embodiment 1, and uses a new low-consumption anode manufacturer to illustrate the use case.

[0037] The waste anode carbon block is cut into a 10mm-thick sheet using a diamond wire saw, and is covered on both side vertical surfaces of the carbon anode. In order to fit the anode corners, the edge of the waste anode carbon block is concave, so as to be convenient for fitting the anode. High-conductivity graphite adhesive is coated on the side vertical surface of the carbon anode, the carbon covering layer is bonded, and is semi-dried at a certain temperature. A hole is drilled and a screw is tapped on the covering layer, a pre-prepared high-temperature graphite bolt is screwed into the screw hole by graphite conductive adhesive, and is fixed. After the adhesive is solidified and has a temperature, the anode can be replaced and used in a tank. The anode consumption reaches 410kg / T.Al or below.

[0038] The above is only a preferred embodiment of the present application, and does not limit the technical scope of the present application. Therefore, any slight modification, equivalent change and modification made according to the technical essence of the present application still belongs to the scope of the technical solution of the present application.
