Description

Technical Field

[0001] The utility model relates to the field of intelligent detection of aluminum electrolysis, in particular to a heat insulation bracket and an on-line detection system for anode current distribution of an aluminum electrolytic cell containing the heat insulation bracket. Background Technique

[0002] With the rapid development of technology and the transformation and upgrading of the global manufacturing industry, the transformation towards digitalization, informatization, and intelligentization has become an important trend in the development of the non-ferrous metal smelting industry. Strengthening the construction of the industry's digital infrastructure and enhancing intelligent detection are extremely urgent. The working state of the anode of an aluminum electrolytic cell not only affects economic and technical indicators such as the current efficiency, power consumption, and carbon consumption of the anode per ton of aluminum of the aluminum electrolytic cell, but also determines whether the production status of the aluminum electrolytic cell is normal. All along, due to the working environment of high temperature, strong magnetism, dust, and corrosion in aluminum electrolysis, as well as factors such as low cost, easy installation, high detection accuracy, and long service life required for industrial promotion, on-line detection of the anode current of aluminum electrolytic cells has not been industrially promoted, and it still relies on manual measurement with a multimeter.

[0003] The prior art CN110501561A discloses an on-line detection system for anode current distribution of an aluminum electrolytic cell. Workers can remotely control an anti-magnetic and high-temperature resistant linear motor through a remote control to drive the voltage contact and temperature sensor to be in close contact with or separated from the anode rod, easily realizing the acquisition of potential signals and temperature signals, avoiding the operation mode of manually climbing onto the electrolytic cell to individually install or disassemble the current detection device one by one, and greatly improving the usability and safety. However, when the temperature of the electrolysis workshop as a whole rises in summer, since the large anode busbar is in direct contact with the wiring groove, the temperature of the integrated drive and detection module placed in the wiring groove will be too high, which will affect the accuracy of the detection data and the service life of the integrated drive and detection module during long-term use. Summary of the Invention

[0004] In order to solve the above problems, the utility model provides a heat insulation bracket for an on-line detection system for anode current distribution of an aluminum electrolytic cell, which separates the fiberglass bridge from the large anode busbar to reduce heat conduction, thereby improving the accuracy and service life of the on-line detection system for anode current of the aluminum electrolytic cell.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: A heat insulation bracket for an on-line detection system for anode current distribution of an aluminum electrolytic cell, the heat insulation bracket includes a bracket body and support blocks, the support blocks are arranged on both sides of the bracket body and are integrally formed with the bracket body, the bracket body is provided with a support groove, a limit groove, and heat dissipation holes, the support groove and the limit groove are respectively arranged at the upper and lower parts of the bracket body, and the opening directions of the support groove and the limit groove are opposite, the heat dissipation holes are long strip-shaped and are arranged between the support groove and the limit groove, and the support blocks are provided with threaded holes.

[0006] The bracket body is also provided with a patch integrally formed therewith, and the patch is arranged at the bottom of the limiting groove and perpendicular to the bracket body.

[0007] The thickness of the bracket body is 1.5 mm.

[0008] The on-line detection system for the anode current distribution of the aluminum electrolytic cell includes a motor sampling mechanism, a driving and detecting integrated module, a fiberglass bridge, a large anode bus, anode guide rods, a control cabinet and a server. The motor sampling mechanism is correspondingly arranged with the anode guide rods and fixedly connected to the large anode bus.

The driving and detecting integrated module is connected to the control cabinet through a multi-core cable, and the control cabinet is communicatively connected to the server. The fiberglass bridge is connected to the support groove, and the large anode bus is connected to the limiting groove. The large anode bus and the support block are connected by bolts so that the heat insulation bracket is relatively fixed to the large anode bus.

[0009] There are at least two heat insulation brackets, which are uniformly arranged along the axial direction of the fiberglass bridge.

[0010] The beneficial effects of the present utility model are as follows: By arranging the heat insulation bracket to separate the fiberglass bridge and the large anode bus, heat conduction is reduced, the temperature of the driving and detecting integrated module in the fiberglass bridge is lowered, the accuracy and service life of the on-line detection system for the anode current of the aluminum electrolytic cell are improved.

[0016] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part rather than all of the embodiments of the present utility model.

[0017] The technical solutions of the present utility model will be described in detail below with specific embodiments. These specific embodiments can be combined or replaced according to actual situations. The same or similar concepts or processes may not be repeated in some embodiments. Embodiment

[0018] As Figures 1 to 3 shown, the present utility model provides a heat insulation bracket for an on-line detection system of anode current distribution in an aluminum electrolysis cell. The heat insulation bracket 6 includes a bracket body 61 and support blocks 62. The support blocks 62 are arranged on both sides of the bracket body 61 and integrally formed with the bracket body 61. The bracket body 61 is provided with a support groove 63, a limit groove 64 and heat dissipation holes 65. The support groove 63 and the limit groove 64 are respectively arranged at the upper and lower parts of the bracket body 61, and the opening directions of the support groove 63 and the limit groove 64 are opposite. The heat dissipation holes 65 are strip-shaped and arranged between the support groove 63 and the limit groove 64. The support block is provided with threaded holes.

[0019] The on-line detection system of anode current distribution in the aluminum electrolysis cell includes a motor sampling mechanism 1, a drive and detection integrated module 8, a fiberglass bridge 7, a large anode bus 4, an anode guide rod 3, a control cabinet 9 and a server 10. The motor sampling mechanism 1 is correspondingly arranged with the anode guide rod 3 and fixedly connected to the large anode bus 4. The external anti-magnetic high-temperature cable 2 of the motor sampling mechanism 1 passes through the bridge reserved hole 5 on the side of the fiberglass bridge 7 and is connected to the drive and detection integrated module 8. The drive and detection integrated module 8 is connected to the control cabinet 9 through a multi-core cable 11. The control cabinet 9 is communicatively connected to the server 10. The fiberglass bridge 7 is connected to the support groove 63, and the large anode bus 4 is connected to the limit groove 64. The large anode bus 4 and the support block 62 are bolted together to relatively fix the heat insulation bracket 6 and the large anode bus 4.

[0020] By arranging the heat insulation bracket 6 to separate the fiberglass bridge 7 and the large anode bus 4, heat conduction is reduced, the temperature of the drive and detection integrated module 8 in the fiberglass bridge 7 is lowered, and the accuracy and service life of the on-line detection system of anode current in the aluminum electrolysis cell are improved. To improve the heat insulation performance and support stability, the overall height and width of the heat insulation bracket 6 can be adjusted according to the size of the large anode bus 4 and the distance required to separate the fiberglass bridge 7 and the large anode bus 4 in actual production. At the same time, the heat insulation bracket 6 in this example is made of a metal thin plate and only uses cutting and bending processes, which can not only ensure the overall light weight of the detection system but also effectively reduce the processing cost.

[0021] Specifically, the thickness of the bracket body 61 is 1.5 mm.

[0022] Specifically, the bracket body 61 is further provided with a patch 66 integrally formed therewith. The patch 66 is arranged at the bottom of the limiting groove 64 and is perpendicular to the bracket body 61. The patch 66 is formed by bending a part of the bracket body 61 and is closely attached directly above the positive anode busbar 4 to ensure that the heat insulation bracket 6 does not shake.

[0023] Specifically, in order to enhance the support stability, at least two heat insulation brackets 6 are provided and are uniformly arranged along the axial direction of the fiberglass bridge 7. In this embodiment, considering the size of the fiberglass bridge 7 to be supported, 3 heat insulation brackets 6 are used for support.

[0024] In addition to the above preferred embodiments, the present utility model has other implementation manners. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection claimed by the present utility model.
