[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Example 1:
[0026] Please see Figs. 1-3 As shown, an automatic electrode-switching ultrafine insulation material blending device for an electrolysis workshop includes:
[0027] The PLC control system, which serves as the central hub of the entire blending process, is responsible for receiving instructions, processing signals, and issuing control commands.
[0028] The bucket elevator, driven by a motor, lifts block insulation material from a lower location to a higher insulation silo. The design of the bucket elevator ensures that the block insulation material can be stably and continuously transported to the designated location.
[0029] An air-lift device uses gas pressure or suction to transport sheet-like insulation material to an elevated insulation silo. The air-lift device works in conjunction with a bucket elevator to achieve uniform mixing of the insulation material.
[0030] The dust collector is located upstream of the bucket elevator and the air lift device. It is used to remove the dust generated during the blending process, maintain the cleanliness of the working environment, and protect the normal operation of other equipment.
[0031] The start signal module is used to receive start commands from the operator and convert them into electrical signals to send to the PLC control system.
[0032] The delay signal module, connected to the PLC control system, is used to sequentially start the bucket elevator and air-lift device according to a preset delay time after receiving a start signal. This delayed start ensures the dust collector has sufficient time to reach a stable operating state, thereby effectively reducing the impact of dust on the blending process.
[0033] The feedback signal module is used to monitor the operating status of the bucket elevator and air-lift device in real time and feed these status signals back to the PLC control system. When the equipment malfunctions or malfunctions, the feedback signal module can immediately issue an alarm to ensure that timely measures are taken to prevent further losses.
[0034] It also includes a safety protection module, which connects to the PLC control system. When the equipment malfunctions or experiences an abnormal state, the safety protection module can automatically stop operation and issue an alarm to prevent the fault from escalating further, ensuring the safety of operators and the stable operation of the equipment.
[0035] The PLC control system includes a preset program that sequentially controls the start and stop of the dust collector, bucket elevator, and air lift unit based on start and delay signals. The delay signal module has an adjustable delay time setting to be adjusted according to different process requirements and equipment characteristics.
[0036] Example 2:
[0037] Please see Figs. 1-3 As shown, based on Example 1, further optimization is made by adding an intelligent monitoring module. This module can monitor the mixing process of the insulation material in real time, including key parameters such as the conveying amount and mixing ratio of block insulation material and surface insulation material. When abnormal parameters are detected, the intelligent monitoring module can automatically adjust the control strategy to ensure the stability and accuracy of the mixing process.
[0038] The program of the PLC control system is optimized and upgraded to improve the system's response speed and stability. At the same time, remote control and fault diagnosis functions are added, enabling operators to monitor and operate the equipment remotely, which greatly improves work efficiency and equipment reliability.
[0039] The structures of the bucket elevator and air-lift devices were improved, and more wear-resistant and corrosion-resistant materials were used to extend the service life of the equipment. At the same time, the conveying efficiency of the equipment was optimized, making the mixing process of the insulation material more efficient and energy-saving.
[0040] Example 3:
[0041] Please see Figs. 1-3As shown, in the aluminum electrolysis production process, the uniform mixing of insulation material is crucial for maintaining the stable temperature of the electrolytic cell and ensuring the normal operation of aluminum electrolysis. Traditional insulation material mixing methods often rely on manual operation and multi-step communication, which is not only inefficient but also easily leads to uneven mixing of block insulation material and surface insulation material, affecting the temperature maintenance and process requirements of the aluminum electrolysis cell. Therefore, this device is used to solve these problems.
[0042] Large-scale aluminum electrolysis plants have multiple electrolysis workshops, and each workshop needs to add insulation material to the electrolysis cells regularly. Traditional mixing methods result in uneven mixing of the insulation material, which affects the stability and production efficiency of the electrolysis cells.
[0043] Equipment deployment: Install an automatic electrode-changing ultrafine insulation material blending device (PTM) in each electrolysis workshop, including key components such as a PLC control system, bucket elevator, air-lifting device, dust collector, start signal module, delay signal module, and feedback signal module.
[0044] System debugging: Based on the actual needs and equipment characteristics of the electrolysis workshop, the PLC control system is programmed and debugged to ensure that each component can start and stop in an orderly manner according to the preset program, so as to achieve uniform mixing of insulation material.
[0045] Operational training: Provide training on equipment operation and daily maintenance to operators in the electrolysis workshop to ensure they are proficient in using the equipment and understanding the precautions.
[0046] Operation monitoring: During equipment operation, the operating status of the equipment and the mixing of insulation material are monitored in real time through the feedback signal module of the PLC control system, so as to promptly detect and handle abnormal situations.
[0047] After being started with a single button press via the PLC program, the dust collector is first activated via a start signal. Upon receiving a signal indicating normal start-up of the dust collector, a delay signal is used to wait 3 minutes for the dust collector to fully commence operation before starting the bucket elevator. After receiving a signal indicating normal start-up of the bucket elevator, the elevator is waited to run for 2 minutes before the air lift is activated to spray and elevate the surface insulation material into the hopper for mixing.
[0048] After the bucket elevator finishes feeding and is shut down with one button, it runs for 2 minutes to allow all remaining insulation material in the bucket elevator to be lifted into the hopper. Then, the air-lift bucket elevators are shut down one by one, and finally the dust collector is turned off. During the process, the equipment feedback signal is used to ensure that the equipment shuts down normally before proceeding to the next start-up and shutdown. This ensures that if the equipment fails to start or stop normally, it will not cause more losses and impacts, thus completing the feeding and mixing of insulation material.
[0049] Application effect:
[0050] The automated mixing device enables rapid and uniform mixing of insulation materials, greatly improving production efficiency. Through precise program control and real-time monitoring, it ensures the uniformity of the insulation material mixing, meeting production process requirements. The automated mixing device reduces manual operation and message transmission steps, lowering labor and time costs. The built-in safety protection module can automatically stop operation and issue an alarm in the event of a fault or abnormal state, preventing the fault from escalating further and improving production safety.
[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
