Description

Technical Field

[0001] The utility model relates to the technical field of cathode steel rod casting, in particular to a copper-embedded cathode steel rod casting machine for aluminum electrolysis. Background Art

[0002] Cathode steel rod plays a very important role in electrolytic production. Its quality and reasonable design directly affect whether the electrolytic production can be stable, efficient and the production cost. Therefore, reducing the voltage drop is an important way to reduce the DC power consumption of aluminum liquid. In the large-scale process of aluminum electrolytic cells, the cathode rod consists of two parts, namely the cathode rod connected to the workpiece and the clip fixed to the edge of the plating tank. The cathode rod is generally composed of a copper core and a steel rod. In order to ensure that the copper core is in close contact with the steel rod, a pouring machine is often used to cast the copper core into the steel rod by high-temperature melting.

[0003] In the prior art, molten copper is generally poured into a steel rod with slots by a pouring machine. After the molten copper is cooled and formed in the steel rod, a cathode rod consisting of a copper core and a steel rod is obtained, namely, a copper-embedded cathode steel rod. However, during the pouring and forming process, it is difficult to pour the copper core into multiple steel rods at the same time, which easily leads to the problem of low pouring efficiency. Moreover, after the high-temperature molten copper is poured into the steel rod, there is a lack of rapid cooling measures, resulting in the copper core not being cooled and formed in the steel rod fast enough, thereby affecting the overall pouring and forming efficiency of the cathode steel rod.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-7 The utility model provides a technical solution: a copper-embedded cathode steel bar pouring machine for aluminum electrolysis, comprising a frame 1 and a pouring box 2, wherein the pouring box 2 is fixed to the upper end of the frame 1, and a water bath cooling box 3 with an opening facing upward is fixed to the bottom end of the frame 1, a hollow cover 5 is fixed in the water bath cooling box 3, and a plurality of mesh positioning sleeves 4 are fixed to the upper end of the hollow cover 5, and elastic positioning components are arranged around the inner wall of the mesh positioning sleeve 4, and the elastic positioning components include limiting springs 15 and a plurality of return springs 16, the limiting springs 15 are connected to the inner wall of the mesh positioning sleeve 4, and the return springs 16 are connected between the outer side of the limiting springs 15 and the inner wall of the mesh positioning sleeve 4, and a top plate 13 is arranged at the lower end of the mesh positioning sleeve 4.

[0028] When the copper-embedded cathode steel rod is cast and formed by the casting machine, on the premise that the steel rod is provided with slots for embedding the copper core, a plurality of steel rods with slots are inserted into the mesh positioning sleeve 4 one by one, with the slot openings of the steel rod facing upward. During this process, the steel rod will squeeze the limiting spring 15, and the limiting spring 15 will compress the return spring 16 until the steel rod is supported by the top plate 13. At this time, the limit spring 15 is driven by the elasticity of the return spring 16 to clamp the steel rod around, so as to prevent the steel rod from tilting in the mesh positioning sleeve 4, so as to prepare for the subsequent accurate pouring of copper water into the steel rod.

[0029] In this embodiment, a shunt pipe 8 is provided under the pouring box 2, and a plurality of pouring pipes 9 are connected to the lower end of the shunt pipe 8. The plurality of pouring pipes 9 correspond to a plurality of mesh positioning sleeves 4 one by one up and down. The outer periphery of the pouring pipes 9 is fixedly sleeved with a positioning plate 10. The lower end of the pouring box 2 is connected to a metering valve 6, and a telescopic tube 7 is connected between the metering valve 6 and the shunt pipe 8. An electric cylinder 11 is fixed to the lower end of the pouring box 2, and the power end of the electric cylinder 11 is connected to the upper end of the shunt pipe 8.

[0030] After the steel rod is installed in the mesh positioning sleeve 4, under the premise that there is molten copper in the casting box, the extension of the electric cylinder 11 drives the shunt pipe 8, the pouring pipe 9 and the positioning plate 10 to move downward together, and the shunt pipe 8 stretches the telescopic pipe 7 downward until the multiple pouring pipes 9 are aligned one by one with the steel rod slots in the corresponding mesh positioning sleeve 4. At this time, the positioning plate 10 is pressed on the mesh positioning sleeve 4, and then the copper water in the casting box 2 is discharged into the telescopic pipe 7 and the shunt pipe 8 through the work of the quantitative valve 6, and then the shunt pipe 8 divides the copper water into the pouring pipe 9, and finally the copper water is injected into the slot of the steel rod through the pouring pipe 9. Since multiple pouring pipes 9 pour copper water into multiple steel rods at the same time, it is beneficial to pour the formed copper core into multiple steel rods at the same time, effectively ensuring the pouring efficiency.

[0031] In this embodiment, a water bath cooling box 3 with an upward opening is fixed at the bottom end of the frame 1, a hollow cover 5 is fixed in the water bath cooling box 3, a plurality of mesh positioning sleeves 4 are fixed at the upper end of the hollow cover 5, a water inlet pipe 20 is connected to the upper left end of the water bath cooling box 3, and a drain valve 14 is connected to the lower part of the front end of the water bath cooling box 3.

[0032] After the copper water in the steel rod is poured, the quantitative valve 6 stops working. At the same time, the water inlet pipe 20 is connected to the external water source, and then the external water is introduced into the water bath cooling box 3 through the water inlet pipe 20. After the water in the water bath cooling box 3 is filled, the water is not higher than the steel rod at this time to prevent water from entering the steel rod groove. Then the cold water contacts the steel rod through the mesh of the mesh positioning sleeve 4, and the water bath cooling method is used to quickly cool and shape the copper water in the steel rod, so as to quickly cast and shape the cathode steel rod composed of the copper core and the steel rod, effectively improving the efficiency of the cathode steel rod casting and forming, and when the steel rod and the copper water are cooled by the water bath method, the drain valve 14 is opened at the same time, and the drain valve 14 discharges the water after heat exchange, and the water inlet pipe 20 continuously adds cold water into the water bath cooling box 3, so that there is always enough cooling water in the water bath cooling box 3, which is conducive to ensuring the cooling effect of the steel rod.

[0033] In this embodiment, a lifting drive assembly is provided in the hollow cover 5, and the lifting drive assembly includes a screw motor 17, a lifting screw 18, a lifting plate 19 and a plurality of push rods 12. The screw motor 17 is fixed at the top of the hollow cover 5, one end of the lifting screw 18 is connected to the power end of the screw motor 17, and the other end of the lifting screw 18 is rotatably connected to the bottom end of the hollow cover 5. The lifting plate 19 is slidably connected to the hollow cover 5, and the lifting screw 18 is threaded through the lifting plate 19 from top to bottom. The push rods 12 are fixed to the upper end of the lifting plate 19, and the push rods 12 slide upward to penetrate the hollow cover 5. The upper ends of the plurality of push rods 12 are fixed one by one to the lower ends of the plurality of top plates 13.

[0034] After the copper core is cooled and formed in the steel rod, the contraction of the electric cylinder 11 drives the shunt pipe 8, the pouring pipe 9 and the positioning plate 10 to move up and reset, and then the operation of the screw motor 17 drives the lifting screw 18 to rotate. The screw motor 17 is preferably waterproof to avoid damage to the screw motor 17 when it encounters water. Therefore, when the screw motor 17 drives the lifting screw 18 to rotate, it will drive the lifting plate 19 to move upward, and the lifting plate 19 will drive the top rod 12 and the top plate 13 to move upward together. Therefore, the top plate 13 will push the steel rod upward until the upper end of the steel rod moves out of the mesh positioning sleeve 4, which is conducive to conveniently and quickly lifting the cast-formed steel rod out of the mesh positioning sleeve 4, thereby facilitating the removal and unloading of the formed steel rods one by one.

[0035] In this embodiment,

[0036] Working principle:

[0037] By inserting a plurality of steel bars with slots into the mesh positioning sleeve 4 one by one, the limit spring 15 is driven by the elasticity of the return spring 16 to clamp the steel bars around, and then the electric cylinder 11 is extended to drive the shunt pipe 8, the pouring pipe 9 and the positioning plate 10 to move downward together, until the plurality of pouring pipes 9 are aligned one by one with the steel bar slots in the corresponding mesh positioning sleeve 4, and then the copper water in the pouring box 2 is discharged into the telescopic pipe 7 and the shunt pipe 8 through the work of the quantitative valve 6, and then the copper water is diverted into the pouring pipe 9 by the shunt pipe 8, and finally the copper water is injected into the slots of the steel bars through the pouring pipe 9. When the copper water in the steel bars is poured, the quantitative valve 6 stops working and the outer Part of the water is introduced into the water bath cooling box 3 through the water inlet pipe 20. After the water in the water bath cooling box 3 is filled with water, the water bath cooling method is used to quickly cool and shape the copper liquid in the steel rod. After the copper core is cooled and shaped in the steel rod, the diverter pipe 8, the pouring pipe 9 and the positioning plate 10 are moved up and reset through the contraction of the electric cylinder 11. Then, when the lifting screw 18 is driven by the screw motor 17 to rotate, the lifting plate 19 is driven to move upward. The lifting plate 19 drives the top rod 12 and the top plate 13 to move upward together. Therefore, the top plate 13 will push the steel rod upward until the upper end of the steel rod moves out of the mesh positioning sleeve 4, so that the formed steel rods can be taken out one by one for unloading.

[0038] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
