Description

Technical Field

[0001] The utility model relates to the technical field of intelligent crust breaking for aluminum electrolysis, and particularly to a wireless remote control system for the upper crust breaking cylinder of an electrolytic cell. Background Technique

[0002] In the process of aluminum electrolysis production, crust breaking and feeding are basic operations, which need to be performed thousands of times a day. The crust breaking cylinder is one of the important crust breaking mechanism components on the upper part of the electrolytic cell, and is an important device to ensure the smooth input of alumina, the production raw material, into the electrolytic cell. Its operation stability directly affects the stability of aluminum electrolysis production.

[0003] An electrolytic cell usually has multiple cylinder crust breaking points. The control mode of the crust breaking cylinder mainly relies on the electrolytic cell control machine, supplemented by an intelligent crust breaking system. When manually performing crust breaking, the crust breaking control mode can be selected according to the on-site needs, and manual crust breaking can be achieved by operating the corresponding buttons on the intelligent crust breaking system control cabinet. When the electrolysis operator inspects the electrolytic cell, in order to accurately judge the smoothness of the electrolytic cell's fire hole and the effectiveness of the crust breaking cylinder's action, it is necessary to shuttle between the electrolytic cell and the control cabinet for observation. This operation process has the following defects: (1) The inspection cycle of the electrolytic cell becomes longer, the workload of personnel is large, and the work efficiency is low; (2) It is necessary to switch the crust breaking control mode back and forth according to the on-site situation, the operation is cumbersome, and it is easy to cause misoperation; (3) It is necessary to observe the electrolytic cell in real time on-site for manual crust breaking operations. The repeated operations cause the crust breaking cylinder to act frequently, increasing the gas consumption of the crust breaking cylinder, accelerating the wear of the crust breaking hammer head itself, and shortening the service life of the crust breaking cylinder. In the case of maintenance, it often requires two people to cooperate. One person operates on the electrolytic cell control machine, and the other person deals with the faults at the electrolytic cell, resulting in a waste of manpower. Moreover, during the maintenance process, if the electrolytic cell control machine and the electrolysis operator are out of step, it is easy to cause potential safety hazards.

[0018] 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 some but not all of the embodiments of the present utility model. Generally, the components of the embodiments of the present utility model described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0019] Figure 1 Schematic diagram of the architecture of a wireless remote control system for the upper cell shell breaking cylinders of the present utility model to the first preferred embodiment. This wireless remote control system is applicable to an aluminum electrolysis system composed of at least one electrolysis cell controller and at least one electrolysis cell, such as Figure 1 As shown, a wireless remote control system for the upper cell shell breaking cylinders of the present utility model includes a handheld terminal, an intelligent shell breaking control unit and an interlock circuit.

[0020] Among them, the intelligent shell breaking control unit is improved based on the existing intelligent shell breaking control system. The intelligent shell breaking control unit includes a wireless receiving controller and a shell breaking controller. The wireless receiving controller is also electrically connected to a power module. The handheld terminal includes a wireless transmitting module. The wireless receiving controller includes an antenna interface. The wireless receiving controller is connected to a receiving antenna through the antenna interface. The wireless transmitting module communicates with the wireless receiving controller through the receiving antenna.

[0021] The first input end of the interlock circuit is electrically connected to the wireless receiving controller. The second input end of the interlock circuit is electrically connected to the electrolysis cell controller. The output end of the interlock circuit is electrically connected to the shell breaking controller. The shell breaking controller is electrically connected to several upper cell shell breaking cylinders.

[0022] In this embodiment, the crust-breaking controller can obtain control instructions through three channels. First, the electrolysis operator sends control signals (which can be signals such as crust-breaking cylinder selection, crust-breaking cylinder mode switching, crust-breaking cylinder control parameters, etc.) through the wireless transmission module of the handheld terminal to the wireless receiving controller via the receiving antenna. The wireless receiving controller receives the control signal and sends the control signal to the crust-breaking controller. Second, the electrolysis operator sends control signals to the crust-breaking controller through the control cabinet of the intelligent crust-breaking control system. Third, the electrolysis operator sends control signals to the crust-breaking controller through the electrolytic cell control machine.

[0023] The interlock circuit in this embodiment can ensure that the crust-breaking controller can only obtain control signals through one channel at the same time. That is to say, the handheld terminal, the electrolytic cell control machine, and the control cabinet of the intelligent crust-breaking control system cannot send control signals to the crust-breaking controller simultaneously, avoiding potential safety hazards caused by the simultaneous operation of the handheld terminal, the electrolytic cell control machine, and the control cabinet of the intelligent crust-breaking control system on the crust-breaking controller. The wireless remote control system of this embodiment further includes an alarm unit, which is electrically connected to the crust-breaking controller. If the crust-breaking controller receives control signals sent by the handheld terminal, the electrolytic cell control machine, and the control cabinet of the intelligent crust-breaking control system at the same time, it indicates that the interlock circuit has failed, and at this time, the alarm unit issues an alarm.

[0024] In summary, during maintenance, remote operation can be achieved through the handheld terminal. The electrolysis operator can complete the operation alone without the need for multiple people to cooperate and guide the operation, and the probability of misoperation is low, greatly improving safety.

[0025] In this embodiment, the handheld terminal further includes a processor and a display screen. The processor is electrically connected to the display screen and the wireless transmission module respectively. The handheld terminal further includes several function buttons, and the function buttons include a crust-breaking cylinder selection button and a crust-breaking cylinder mode selection button. The crust-breaking controller includes a main board and a sub-board. The crust-breaking cylinder selection button and the crust-breaking cylinder mode selection button are each divided into two groups, and one group of the crust-breaking cylinder selection button and the crust-breaking cylinder mode selection button is provided on the main board and the sub-board respectively. Through the handheld terminal, the control of multiple points of the wireless receiving controller can be realized, so as to control the crust-breaking cylinder through the corresponding main board or sub-board, and the motion state of the controlled crust-breaking cylinder is displayed in real time through the display screen.

[0026] In summary, through the handheld terminal, control signals can be sent to the intelligent crust-breaking control unit while observing the electrolytic cell in real time, realizing remote operation and control of the crust-breaking cylinder, with high execution efficiency, optimizing the entire electrolytic cell inspection operation process, reducing the operation intensity of electrolysis operations, reducing the number of actions of the crust-breaking cylinder during inspection, and reducing the consumption of compressed air.

[0027] Further, it further includes a cell voltage acquisition unit. The output end of the cell voltage acquisition unit is electrically connected to the crust breaking controller, and the input end of the cell voltage acquisition unit is electrically connected to the cathode busbar at the bottom of the cell, for acquiring the cell voltage, so as to adjust the crust breaking depth and crust breaking frequency of the crust breaking cylinder through the crust breaking controller.

[0028] In the second preferred embodiment of the present invention, the wireless transmission module has multiple access points, each access point corresponding to an electrolytic cell. The wireless receiving controllers of each electrolytic cell are set with a fixed address as a signal transmission channel according to the cell number. By manually inputting a value to match the address of the receiving controller to be controlled, a feedback execution channel for the crust breaking command is established, so that the handheld terminal can control multiple electrolytic cells, and details are not elaborated here.

[0029] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
