Description

Technical Field

[0001] This utility model relates to the electrolysis process of the anode furnace, specifically to an electrical control system for the liquid level of the anode mud pit. Background Technology

[0002] After copper ore is smelted in an Osmite furnace and other processes, it produces crude copper and other crude metals, as well as slag. The crude copper dissolves in subsequent electrolysis processes, while precious metals, impurities, and other insoluble substances deposit as anode mud. Improper handling of anode mud can pollute the environment, and it also has significant economic value, thus requiring recycling. In existing technologies, the bottom of the electrolytic cell is typically connected to a pit, where the anode mud produced after electrolysis is temporarily stored. The turbid liquid from the anode mud is then pumped to a dedicated anode mud treatment station. In this process, controlling the liquid level in the anode mud pit usually requires manual operation of the pumping equipment for drainage, which is labor-intensive and prone to operational errors. Therefore, it is necessary to upgrade this process to an automated system. Utility Model Content

[0003] The purpose of this invention is to provide an electrical control system for the liquid level of an anode mud pit, which monitors the liquid level of the anode mud pit in real time and controls the drainage.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an electrical control system for the liquid level of an anode mud pit, wherein the bottom of the electrolytic cell is connected to the anode mud pit, a liquid level sensor is installed in the pit, the liquid level sensor is connected to the distributed control system through a liquid level transmitter, the pump inlet pipe extends into the pit, and when the liquid level in the pit is higher than the preset height, the distributed control system controls the pump to pump the anode mud turbid liquid in the pit to the anode mud treatment station.

[0005] The main feature of this invention is that a liquid level sensor is installed in the anode mud pit. The distributed control system controls the water pump to extract the turbid liquid in the pit and discharge it based on the liquid level information collected by the sensor. This eliminates the need for on-site manual monitoring of the pit's working conditions, thus improving the convenience and safety of liquid level monitoring. Attached Figure Description

[0006] Figure 1 This is a schematic diagram of the electrical control system for the liquid level in the anode mud pit. Detailed Implementation

[0007] See Figure 1The anode mud pit liquid level electrical control system shown has an electrolytic cell 1 connected to the bottom of the anode mud pit 10. A liquid level sensor 21 is installed in the pit 10. The liquid level sensor 21 is connected to the distributed control system 40 through a liquid level transmitter 20. The inlet pipe of the pump 30 extends into the pit 10. When the liquid level in the pit 10 is higher than the preset height A0, the distributed control system 40 controls the pump 30 to pump the anode mud turbid liquid in the pit 10 to the anode mud treatment station.

[0008] In the above scheme, the level sensor 21 can collect the liquid level information of the anode mud suspension in the anode mud pit 10, and convert the liquid level information collected by the level sensor 21 into a standard electrical signal through a level transmitter (LT), which is then remotely transmitted to the distributed control system 40. The distributed control system 40 regulates the operation of the pump 30 according to the processed liquid level information. When the liquid level in the pit 10 is higher than the preset height A0, the pump starts operating according to the control signal issued by the distributed control system 40, pumping out the turbid liquid in the pit 10 and discharging it to prevent it from accumulating in the pit 10. This scheme monitors the anode mud suspension level in real time through the distributed control system 40, eliminating the need for manual on-site monitoring of the pit's operating conditions and improving the convenience and safety of liquid level monitoring.

[0009] To prevent the suspension from the anode mud treatment station from flowing back into the pit 10, a pneumatic valve 50 is connected in series between the pump 30 and the anode mud treatment station. The signal control line of the pneumatic valve 50 is connected to the distributed control system 40. When the liquid level in the pit 10 is higher than the preset height A0, the distributed control system 40 controls the pneumatic valve 50 to open and controls the pump 30 to start; when the liquid level is lower than the preset height A0, the distributed control system 40 controls the pump 30 to stop and controls the pneumatic valve 50 to close.

[0010] Preferably, a stirrer 11 is provided inside the pit 10, and the control signal of the power unit of the stirrer 11 is electrically connected to the distributed control system 40. A scraper 12 is provided on the bottom or side wall of the pit 10. The scraper 12 can scrape off the anode mud deposited on the bottom and side wall of the pit 10, and the stirrer 11 agitates the liquid in the pit 10 to make it into an anode mud suspension, so that the anode mud is mixed in the liquid and discharged, avoiding a large amount of anode mud from depositing at the bottom of the pit.

[0011] In order to monitor the flow rate of the suspension pumped from the pit 10 to the anode mud treatment station, a flow meter 31 is connected in series between the pump 30 and the pneumatic valve 50, and the signal output terminal of the flow meter 31 is connected to the distributed control system 40.

[0012] As a preferred embodiment, when the liquid level in the pit 10 is higher than the high warning height A2, or when the liquid level is lower than the low warning height A1 and the pump 30 is in operation, the alarm 41 receives the control signal from the distributed control system 40 and issues an alarm. When the liquid level in the pit 10 is too high, there is a risk that the anode mud suspension will overflow the pit 10. Under normal operating conditions, the pump 30 will stop working when the liquid level in the pit 10 is lower than the preset height A0. If the pump 30 is still running when the liquid level is lower than the low warning height A1 due to equipment failure or other reasons, the pump 30 may be in an idling state, and the alarm 41 will issue an alarm to remind the staff to troubleshoot the fault.
