Description

[0001] Technical field: The top extrusion molding die of an anode carbon block vibration molding machine described in the present invention is mainly used in the production of anode carbon blocks prepared for aluminum electrolytic cells and the configuration of a vibration molding machine.

[0002] In the process of electrolytic aluminum production, the anode carbon block used is not only a raw material component participating in the thermoelectrochemical replacement reaction of aluminum electrolysis, but also an anode conductive component that conducts the anode current to the electrolyte; in order to realize its function of conducting the anode current of the anode busbar of the aluminum electrolytic cell to the anode carbon block. The existing anode conductive device of the aluminum electrolytic cell is to prefabricate a number of concave circular carbon bowls on the upper part of the prebaked anode carbon block, and then use the method of casting phosphorus iron rings to structurally connect the anode steel claw head set at the bottom of the anode metal conductive device with the anode carbon block, forming an integral anode conductive device composed of an aluminum guide rod and an explosion welding piece on the upper part and an anode steel claw and anode carbon on the lower part.

[0003] In the existing electrolytic aluminum production process, the anode steel claw and anode carbon are combined by casting phosphorus pig iron to form an anode conductive device, which has the following technical defects: first, a large amount of electric energy is consumed to melt phosphorus pig iron during anode assembly; second, a large amount of manpower, material resources and mechanical equipment are required for assembly; third, the connection resistance value between the anode carbon block and the anode steel claw head and the voltage drop of the iron-carbon structure are high, and a large amount of electrolytic DC power consumption will be lost during the electrolysis process, resulting in a decrease in the current efficiency of the aluminum electrolytic cell.

[0004] In order to overcome the technical defects of the prior art, such as high connection voltage drop, high assembly energy consumption, complex process and high construction cost of the anode conductive device formed by assembling the anode carbon block and the anode steel claw together using a cast ferrophosphorus ring, the inventor of this case proposed a new innovative assembly technology solution for the anode conductive device.

[0005] The innovative technical solution of the anode conductive device of the aluminum electrolytic cell is characterized by: the anode steel claws of the existing anode conductive device are eliminated and replaced by anode conductive column plates and anode conductive beams, and then one or two anode conductive concave grooves are constructed on the top of the flat-top anode carbon block. When assembling the anode, the anode conductive beam is directly assembled in the anode conductive concave groove, thereby forming a new type of anode conductive device in which the anode conductive beam is assembled in the anode conductive concave groove on the top of the anode carbon block, and the upper part is structurally connected to the aluminum guide rod. After industrial testing, this innovative technology has achieved relatively ideal technical results. It is now planned to carry out large-scale industrial production applications and technology promotion.

[0006] However, the anode carbon production industry at home and abroad has a history of nearly 100 years in producing products with traditional structures and circular anode boss carbon bowls. At present, the main production equipment of anode carbon block manufacturers, vibration molding, cannot directly produce anode carbon blocks with anode conductive concave grooves on the upper structure required by the innovative technology of electrolytic aluminum due to the limitation of the upper extrusion molding die of the anode carbon block vibration molding machine. In order to promote the innovative technology of constructing anode conductive concave grooves on the upper part of anode carbon blocks and directly constructing anode conductive crossbeams in the anode conductive concave grooves, the only way currently is to use the method of mechanical processing by planing and milling machines to perform secondary mechanical processing on the existing anode carbon block structure, but this undoubtedly increases its production and construction costs, and becomes the main technical obstacle to restricting the promotion of innovative technologies, affecting the technological progress of the electrolytic aluminum industry, and achieving energy conservation, emission reduction and carbon reduction in electrolytic aluminum production.

[0007] Invention content: In order to solve the problem that the vibration molding machine of the existing anode carbon block production equipment cannot construct the anode carbon block required by the innovative technology for producing electrolytic aluminum, which is provided with anode conductive concave grooves and anode conductive cross beams on the upper part for combined structural assembly and connection, the present invention discloses a technical solution for structural improvement of the upper extrusion molding die of the existing anode carbon block vibration molding machine.

[0008] The top extrusion molding die of the anode carbon block vibration molding machine described in the present invention is composed of an anode top molding extrusion cover plate (1), a concave groove extrusion boss module (2), a guide lifting connection plate (3), a lifting extrusion drive device (4), and a vertical guide sleeve (5). The anode top molding extrusion cover plate (1) and the inner cavity of the vibration molding material box (6) arranged on the vibration platform (7) at the bottom of the vibration molding machine are configured with a corresponding interlaced structure. A rectangular extrusion boss module (2) for constructing an anode conductive concave groove (10) is arranged at the bottom of the anode top molding extrusion cover plate (1).

[0009] According to the above technical solution: in an anode carbon block vibration molding machine, a top extrusion molding die, the bottom of the anode top molding extrusion cover plate (1) is provided with one or more concave groove extrusion boss modules (2) for constructing anode conductive concave grooves (10); The anode top forming extrusion cover plate (1) and the concave groove extrusion boss module (2) are integrated structural components. The external contour structure of the anode top forming extrusion cover plate (1) is configured to correspond to the internal contour structure of the vibration forming material box (6) on the upper part of the vibration platform (7) at the bottom of the vibration forming machine; the contour structure of the rectangular extrusion boss module (2) is configured to correspond to the structural contour of the anode conductive beam of the anode conductive metal device to be assembled therein.

[0010] According to the above technical scheme, the existing anode carbon block vibration molding machine is technically modified by adopting the upper extrusion molding die described in the present invention, and the anode carbon block (8) prepared with a conductive concave groove (10) on the top has a depth of the anode conductive concave groove (2) that is less than or equal to the width of the anode conductive concave groove (2).

[0011] In the process of preparing and producing anode carbon blocks, the following technical effects can be achieved by using the upper pressing mold of the anode carbon block vibration forming machine described in the present invention to technically transform the existing anode carbon block vibration forming machine; First, it solves the problem that the existing anode carbon block vibration forming machine cannot produce anode carbon blocks with anode conductive concave grooves on the top, which restricts the industrialization technology promotion of new anode conductive devices, that is, the existing technology uses anode steel claws to cast phosphorus pig iron to construct anode conductive devices, and uses anode conductive cross beams to directly assemble into the anode conductive concave grooves on the top of anode carbon blocks to construct anode conductive devices; second, it provides a set of simple and easy technical solutions for the improvement of existing anode carbon block vibration forming machines. Third, it provides technical equipment innovation and technical support conditions for the energy-saving and carbon-reducing green development of my country's electrolytic aluminum industry.

[0025] Specific implementation method: The technical solution and features expressed by the upper pressure molding die of the inventive anode carbon block vibration molding machine will be more clearly described through the drawings and specific embodiments of the specification.

[0026] Embodiment 1: Figure 1 Figure 2 As shown, the upper extrusion molding die of the anode carbon block vibration molding machine of the present invention is composed of an anode top molding extrusion cover plate (1), a concave groove extrusion boss module (2), a guide lifting connection plate (3), a jacking extrusion drive device (4), and a vertical guide sleeve (5). The anode top molding extrusion cover plate (1) and the inner cavity of the vibration molding material box (6) on the vibration platform (7) at the bottom of the vibration molding machine are correspondingly interlaced and arranged as shown in FIG. Figure 3As shown, a concave groove extrusion boss module (2) for constructing an anode conductive concave groove (10) is arranged at the lower part of the anode top molded extruded cover plate (1).

[0027] When the anode vibration forming machine is used to form pre-baked anode carbon blocks, its production process is basically the same as the existing process; that is, the raw materials for preparing the anode carbon blocks, namely, the mixture of forged petroleum coke and coal tar, are added in a set amount into the inner cavity of the vibration forming material box (6) on the upper part of the vibration platform (7) of the vibration forming machine (9), and then the vibration forming machine is started, so that the anode top forming extrusion cover plate (1) and the concave groove extrusion boss module (2) can be squeezed into the inner cavity of the vibration forming material box (6) of the lower vibration platform (7) of the vibration forming machine under the pushing action of the jacking extrusion drive device (4), as shown in FIG. Figure 3 and Figure 4 As shown; and after the anode carbon block (1) is formed, an anode conductive concave groove (2) is formed on the upper part thereof, which is configured corresponding to the anode conductive cross beam at the bottom of the anode metal conductive device of the aluminum electrolytic cell. Figure 5 and Figure 6 shown.

[0028] The anode carbon block vibration forming machine is equipped with the anode upper extrusion forming die of the present invention, that is, a rectangular extrusion boss module (2) with a concave groove is arranged at the bottom of the anode top forming extrusion cover plate (1), and the anode carbon block produced by the anode carbon block has an anode conductive concave groove that penetrates each other along the length direction of the anode carbon block. Note: The function of the rectangular extrusion boss module (2) is equivalent to the die head of the anode carbon bowl on the existing anode vibration forming machine.

[0029] Embodiment 2, as Figure 7 Figure 8 As shown, the upper pressure forming mold configured on the top of the anode carbon block vibration forming machine of this embodiment 2 is basically the same as that of embodiment 1, and the different technical features are that the lower end of the anode top forming extrusion cover plate (1) in embodiment 1 is a concave groove extrusion boss module (2); while in embodiment 2, there are two concave groove extrusion boss modules (2) that are symmetrical left-right along the center line of the anode carbon block, and whose plan view projection is a rectangular with semicircular arcs at both ends.

[0030] Since the lower end of the anode top forming extrusion cover plate (1) of the vibration forming machine in this embodiment 2 is configured with two rectangular concave groove extrusion boss modules (2), the upper top of the anode carbon block (1) produced by the anode carbon block vibration forming machine is structured with an anode conductive concave groove (2) with two ends being arc-enclosed and configured corresponding to the anode conductive cross beam of the anode metal conductive device of the aluminum electrolytic cell. Fig.11 and Fig.12 shown.
