[0041] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0042] like Figure 1 As shown, the embodiment of the present disclosure provides a shelling structure 100 for an electrolytic cell, comprising: a shelling assembly 110, an automatic shelling valve 120 and a control device 130. The shelling assembly 110 is arranged in the cell body of the electrolytic cell, and the input end is used to communicate with the gas source, and the output end is used to perform a shelling operation on the furnace hole on the electrolytic cell. The input end of the automatic shelling valve 120 is connected to the gas source through a first switch valve 140, and the output end is connected to the input end of the shelling assembly 110 through a second switch valve 150. The control device 130 is electrically connected to the control end of the automatic shelling valve 120, and is used to control the automatic shelling valve 120 to connect and disconnect the shelling assembly 110 with the gas source, and perform a shelling operation on the furnace hole on the electrolytic cell.

[0043] Specifically, by setting an automatic shelling valve 120 whose input end is connected to the gas source and whose output end is connected to the input end of the shelling component 110, the connection state between the gas source and the shelling component 110 can be adjusted, thereby realizing the control of the action of the shelling component 110.

[0044] Specifically, by setting a first switch valve 140 on the communication passage between the automatic shelling valve 120 and the air source, and setting a second switch valve 150 on the communication passage between the automatic shelling valve 120 and the shelling assembly 110, when a problem occurs with the automatic shelling valve 120, the automatic shelling valve 120 can be replaced by closing the first switch valve 140 and the second switch valve 150.

[0045] Specifically, by electrically connecting the control end of the automatic shelling valve 120 to the control device 130, the control of the connection state between the gas source and the shelling assembly 110 can be achieved. In this way, after the measuring mechanism reaches the measurement waiting position on one side of the electrolytic cell, the control device 130 can control the automatic shelling valve 120 to connect or disconnect the shelling assembly 110 with the gas source, so that the output end of the shelling assembly 110 performs a shelling operation on the furnace hole on the electrolytic cell. Or when the measuring mechanism identifies that the type of the furnace hole on the electrolytic cell is the target furnace hole type (i.e., it is identified that there is still crust at the furnace hole position), the control device 130 will control the automatic shelling valve 120 to make the shelling assembly 110 perform a shelling operation on the furnace hole again.

[0046] Optionally, the automatic shelling valve 120 is a center-sealed electromagnetic valve, and the connection state between the shelling cylinder 111 and the air source is controlled by controlling whether the center-sealed electromagnetic valve is ventilated. Figure 1 When the automatic shelling valve 120 is in the left position, the shelling operation is performed at the output end of the shelling assembly 110. Figure 1 When the automatic shelling valve 120 is in the right position, the output end of the shelling assembly 110 rises to complete the shelling operation.

[0047] In the embodiment of the present disclosure, by setting the shell breaking structure 100 for the electrolytic cell as described above, when it is determined that the measuring mechanism has reached the measurement waiting position of the electrolytic cell, or when the feedback information received from the measuring mechanism is that the type of furnace hole on the electrolytic cell is the target furnace hole type, the control device 130 can control the automatic shell breaking valve 120 to connect and disconnect the shell breaking assembly 110 with the gas source, and perform a shell breaking operation on the furnace hole on the electrolytic cell. In this way, it is possible to reduce the occurrence of untimely manual shell breaking, the presence of some crusts after shell breaking that cause scratches on the measuring tool, and the situation where the machine hurts people. Therefore, the embodiment of the present disclosure can improve the sampling efficiency of the measuring mechanism, reduce the risk of damage to the measuring tool of the measuring mechanism, and improve the safety of the sampling process of the measuring mechanism.

[0048] like Figure 1 As shown, in some embodiments, the shelling assembly 110 includes: a shelling cylinder 111 and a shelling connecting rod 112. The input end of the shelling cylinder is used as the input end of the shelling assembly, and is connected to the output end of the automatic shelling valve through the second switch valve. The shelling connecting rod 112 is connected to the output end of the shelling cylinder 111, and is used to perform a shelling operation on the furnace hole on the electrolytic cell under the drive of the shelling cylinder 111.

[0049] Specifically, the shelling cylinder 111 is the power source of the shelling connecting rod 112. By connecting the shelling connecting rod 112 to the output end of the shelling cylinder 111, when the output end of the shelling cylinder 111 is extended, the shelling connecting rod 112 can be driven to move, thereby extending into the furnace hole to realize the shelling operation on the furnace hole.

[0050] In the embodiment of the present disclosure, the shelling cylinder 111 is used as the power component, which does not require anti-magnetic design compared to the use of an electric motor or a motor. In this way, the reliability of the shelling assembly 110 in the high temperature, strong magnetic and dusty environment of the electrolysis workshop is improved.

[0051] like Figure 2As shown, in some embodiments, the shelling structure 100 further includes: a manual shelling valve 160 and a mode switching valve 170. The input end of the manual shelling valve 160 is communicated with the gas source, and the output end is communicated with the input end of the shelling cylinder 111 through the third switch valve 180. The input end of the mode switching valve 170 is communicated with the output end of the manual shelling valve 160 through the fourth switch valve 190, and the output end is communicated with the input end of the shelling cylinder 111 through the second switch valve 150, for switching the automatic shelling mode or the manual shelling mode. The control device 130 is also electrically connected to the control end of the mode switching valve 170, the first switch valve 140, the second switch valve 150, the third switch valve 180 and the fourth switch valve 190, for adjusting the switch state of each valve according to the fault condition occurring during the automatic shelling, so as to switch the automatic shelling mode or the manual shelling mode.

[0052] Specifically, a manual shelling valve 160 is provided, whose input end is connected to the gas source and whose output end is connected to the input end of the shelling cylinder 111, and a mode switching valve 170 is provided, whose input end is connected to the output end of the manual shelling valve 160 and whose output end is connected to the input end of the shelling cylinder 111. The shelling operation of the furnace hole can be realized by manually operating the shelling cylinder 111 through the manual shelling valve 160.

[0053] Specifically, during the automatic control of shelling, the first switch valve 140 , the second switch valve 150 , and the fourth switch valve 190 are in an open state, and the mode switching valve 170 and the third switch valve 180 are in a closed state.

[0054] Specifically, if the automatic shelling fails to work, the shelling can be performed manually. When the shelling is manually controlled, the first switch valve 140, the second switch valve 150 and the fourth switch valve 190 are in a closed state, and the mode switching valve 170 and the third switch valve 180 are in an open state. At this time, the manual shelling operation can be performed by rotating the manual shelling valve 160. In this state, the compressed air can only enter the shelling cylinder 111 from the manual shelling valve 160 through the third switch valve 180 to realize the shelling action.

[0055] Optionally, the mode switching valve 170 may be a two-position three-way solenoid valve.

[0056] In the disclosed embodiment, a manual shelling valve 160 and a mode switching valve 170 are further provided, a second switch valve 150 is provided on the communication passage between the mode switching valve 170 and the shelling cylinder 111, a third switch valve 180 is provided on the communication passage between the manual shelling valve 160 and the shelling cylinder 111, and a fourth switch valve 190 is provided on the communication passage between the input end of the mode switching valve 170 and the manual shelling valve 160. In this way, manual shelling operation can be realized through the manual shelling valve 160, so that when the automatic shelling fails, the manual shelling valve 160 can still be manually operated to perform shelling, thereby improving the reliability of the shelling structure 100.

[0057] like Figure 3 As shown, the embodiment of the present disclosure provides a slot door structure 200 for an electrolytic cell, comprising: the shelling structure 100 for an electrolytic cell as described above, a door body 210, a driving mechanism 220 and a connecting rod assembly 230. The door body 210 is connected to the cell body of the electrolytic cell and can rotate relative to the cell body. The driving mechanism 220 is arranged in the cell body of the electrolytic cell. One end of the connecting rod assembly 230 is connected to the driving mechanism 220, and the other end is connected to the door body 210. The control device 130 is also electrically connected to the driving mechanism 220. When receiving a door opening command or a door closing command sent by a measuring mechanism, the control device 130 is used to control the driving mechanism 220 to output power to drive the connecting rod assembly 230 to pull the door body 210 to rotate relative to the cell body, so as to realize the opening or closing of the door body 210.

[0058] Specifically, the door body 210 is a component used to close or open the furnace hole on the electrolytic cell. The door body 210 is connected to the cell body of the electrolytic cell through a rotatable connection structure (for example, hinges, etc.) to achieve the opening and closing of the door body 210 relative to the furnace hole.

[0059] Specifically, the driving mechanism 220 is a power source for opening and closing the door body 210. Specifically, it can be one of an electric motor, a pneumatic device or a hydraulic device.

[0060] Specifically, a connecting rod assembly 230 is provided, one end of which is connected to the driving mechanism 220 and the other end of which is connected to the door body 210. When the driving mechanism 220 outputs power, the connecting rod assembly 230 can be driven to pull the door body 210 to rotate relative to the slot body.

[0061] Specifically, by connecting the driving mechanism 220 to the control device 130, it is possible to control whether the driving mechanism 220 outputs power. In this way, when the measuring mechanism is about to reach the measurement waiting position corresponding to the electrolytic cell, a door opening instruction can be sent to the control device 130 to control the driving mechanism 220 to output power to drive the connecting rod assembly 230 to pull the door body 210 to rotate relative to the cell body to open the door body 210.

[0062] Specifically, Figure 3 As shown, for the case where the electrolytic cell has two opposing door bodies 210, in this case, two driving mechanisms 220 and two connecting rod assemblies 230 need to be provided correspondingly to connect different door bodies 210 respectively.

[0063] In the embodiment of the present disclosure, by setting a slot door structure 200 for the electrolytic cell as described above, when the measuring mechanism is about to reach the measurement waiting position corresponding to the electrolytic cell, the slot door structure 200 can first control the shell breaking assembly 110 to break the shell, and then control the driving mechanism 220 to output power to drive the connecting rod assembly 230 to pull the door body 210 to rotate relative to the slot body to open the door body 210, exposing the furnace hole. Then, the measuring mechanism controls the measuring tool to be inserted into the electrolytic cell through the furnace hole for sampling. In this way, the risk of manual door opening being untimely or inadequate, as well as the risk of machine injury, can be reduced. Therefore, the embodiment of the present disclosure can improve the sampling efficiency of the measuring mechanism and improve the safety of the sampling process of the measuring mechanism.

[0064] like Figure 4 As shown, the driving mechanism 220 includes: a rotary cylinder 221 and an automatic door opening valve 222. The output end of the rotary cylinder 221 is connected to the connecting rod assembly 230. The input end of the automatic door opening valve 222 is connected to the air source through the first switch valve 140, the output end is connected to the input end of the rotary cylinder 221, and the control end is electrically connected to the control device 130. The automatic door opening valve 222 is used to adjust the connection state between the rotary cylinder 221 and the air source to realize the control of opening or closing of the door body 210.

[0065] Specifically, the rotating cylinder 221 is a component of the driving mechanism 220 for outputting power. By connecting the output end of the rotating cylinder 221 as the output end of the driving mechanism 220 with the connecting rod assembly 230, power can be output through the rotational movement of the rotating cylinder 221, so that the door body 210 can rotate relative to the slot body driven by the connecting rod assembly 230.

[0066] Specifically, since the rotary cylinder 221 is used as the component for outputting power in the embodiment of the present disclosure, the connecting rod assembly 230 needs to adopt a combination of multiple connecting rods to convert the rotary motion of the rotary cylinder 221 into the rotation angle of the door body 210.

[0067] Optionally, the automatic door opening valve 222 is a center leakage type solenoid valve. When controlling the door body 210 to open and close, the connection state between the rotary cylinder 221 and the air source can be controlled by changing the connection position of the center leakage type solenoid valve. For example, when the center leakage type solenoid valve is in the "door opening position" ( Figure 2 When the automatic door opening valve 222 is in the left position shown in the figure), the rotating cylinder 221 can drive the connecting rod assembly 230 to pull the door body 210 open. After it is fully opened, the center leakage solenoid valve will switch to the "center position". Figure 2 When the automatic door opening valve 222 is in the right position as shown, the rotating cylinder 221 can drive the connecting rod assembly 230 to close the door body 210. After it is completely closed, the center-leakage solenoid valve will switch to the "center position".

[0068] Specifically, by arranging the first switch valve 140 on the communication path between the input end of the automatic gate valve 222 and the gas source, the flow of gas from the gas source to the automatic gate valve 222 can be controlled. When the first switch valve 140 is in an open state, the gas can flow smoothly into the automatic gate valve 222. When the first switch valve 140 is closed, the communication between the gas source and the automatic gate valve 222 is cut off to prevent the gas from continuing to flow. In this way, when there are impurities or moisture in the gas source, these substances can be prevented from entering the automatic gate valve 222 by closing the first switch valve 140, thereby protecting the automatic gate valve 222. When the rotating cylinder 221 or the automatic gate valve 222 fails, the gas source can also be cut off by closing the first switch valve 140 to prevent damage to the electrolytic cell.

[0069] In the disclosed embodiment, a rotary cylinder 221 is used as the power component of the driving mechanism 220, which does not require anti-magnetic design compared to using an electric motor or a motor. In this way, the reliability of the driving mechanism 220 working in an environment of high temperature, strong magnetism and dust in the electrolysis workshop is improved.

[0070] like Figure 5 As shown, in some embodiments, the slot door structure 200 further includes: a welding bottom plate 223, a first insulating bottom plate 224 and a first fixing plate 225. The welding bottom plate 223 is disposed on the tank body of the electrolytic cell. The first insulating bottom plate 224 is disposed on the welding bottom plate 223. The first fixing plate 225 is disposed on the first insulating bottom plate 224, and the first fixing plate 225 is used to install the rotating cylinder 221.

[0071] Specifically, by directly connecting the welding bottom plate 223 to the tank body of the electrolytic cell, the first insulating bottom plate 224 is arranged on the welding bottom plate 223, the first fixing plate 225 is mounted on the first insulating bottom plate 224, and the rotating cylinder 221 is mounted on the first fixing plate 225. It can ensure that the rotating cylinder 221 is firmly mounted on the tank body, and the rotating cylinder 221 can be electrically isolated from the tank body of the electrolytic cell, so as to prevent the voltage and current generated by the electrolytic cell during operation from affecting the operation of the rotating cylinder 221, thereby improving the reliability of the operation of the rotating cylinder 221.

[0072] Optionally, the welding base plate 223 is directly welded to the body of the electrolytic cell, the first insulating base plate 224 is mounted to the welding base plate 223 by bolts and nuts, the first fixing plate 225 is mounted to the welding base plate 223 by bolts and nuts, and the rotating cylinder 221 is fixed to the first fixing plate 225 by bolts.

[0073] like Figure 3 As shown, in some embodiments, the slot door structure 200 further includes: a dustproof cover 226. The dustproof cover 226 is installed on the outer side of the rotating cylinder 221.

[0074] Specifically, by installing a dustproof cover 226 on the outside of the rotating cylinder 221 , the influence of dust in the electrolysis workshop on the operation of the rotating cylinder 221 can be effectively reduced, thereby improving the reliability of the operation of the rotating cylinder 221 .

[0075] like Figure 6 As shown, in some embodiments, the slot door structure 200 further includes: a first travel switch 240, a first touch module 241, a second travel switch 242, and a second touch module 243. The first travel switch 240 is disposed in the slot body and is electrically connected to the control device 130. The first touch module 241 is disposed at a position on the door body 210 corresponding to the first travel switch 240. The second travel switch 242 is disposed in the slot body and is electrically connected to the control device 130. The second touch module 243 is disposed at a position on the door body 210 corresponding to the second travel switch 242. Wherein, when the first touch module 241 touches the first travel switch 240, the control device 130 determines that the door opening is completed; when the second touch module 243 touches the second travel switch 242, the control device 130 determines that the door closing is completed.

[0076] Specifically, by setting a first travel switch 240 on the slot body, setting a first touch module at a position corresponding to the first travel switch 240 on the door body 210, and electrically connecting the first travel switch 240 to the control device 130, the door opening state can be detected. If the first touch module 241 touches the first travel switch 240, the control device 130 can determine that the door opening is completed. In this case, the control device 130 can control the rotating cylinder 221 to stop working, and can feedback the information that the door body 210 is opened to the measuring mechanism. So that the measuring mechanism starts sampling.

[0077] Specifically, by setting a second stroke switch 242 on the tank body, setting a second touch module at a position corresponding to the second stroke switch 242 on the door body 210, and electrically connecting the second stroke switch 242 to the control device 130, the door closing state can be detected. If the second touch module 243 touches the second stroke switch 242, the control device 130 can determine that the door opening is completed. In this case, the control device 130 can control the rotating cylinder 221 to stop working, and can feedback the information that the sampling is completed to the control system of the electrolytic cell.

[0078] In the embodiment of the present disclosure, a first travel switch 240, a first touch module 241, a second travel switch 242 and a second touch module 243 capable of detecting the door opening state and the door closing state are provided in the slot door structure 200. In this way, it is conducive to realizing the precise control of the door body 210 opening and closing, and effective safety protection can be performed when the door body 210 is not fully opened or not fully closed.

[0079] like Figure 6 As shown, in some embodiments, the slot door structure 200 further includes: a second insulating bottom plate 244 and a second fixing plate 245. The second insulating bottom plate 244 is disposed on the tank body of the electrolytic cell. The second fixing plate 245 is disposed on the second insulating bottom plate 244, and the second fixing plate 245 is used to install the first travel switch 240 and / or the second travel switch 242.

[0080] Specifically, by setting the second insulating bottom plate 244 on the body of the electrolytic cell, installing the second fixing plate 245 on the second insulating bottom plate 244, and installing the first travel switch 240 and the second travel switch 242 on the first fixing plate 225, it is possible to ensure that the first travel switch 240 and the second travel switch 242 are firmly installed on the body of the electrolytic cell, and to achieve electrical isolation of the first travel switch 240 and the second travel switch 242 from the body of the electrolytic cell, so as to prevent the voltage and current generated by the electrolytic cell during operation from affecting the operation of the first travel switch 240 and the second travel switch 242, thereby improving the reliability of the operation of the first travel switch 240 and the second travel switch 242.

[0081] like Figure 6 As shown, in some embodiments, the tank door structure 200 further includes a buffering and limiting mechanism 250. The buffering and limiting mechanism 250 is disposed on the tank body of the electrolytic tank, and is used to buffer and limit the door body 210 during the process of opening the door body 210.

[0082] Specifically, by providing a buffering and limiting mechanism 250 on the body of the electrolytic cell, the door body 210 can be buffered and limited during the opening process of the door body 210 to prevent direct collision with the body of the electrolytic cell and damage to the door body 210. In this way, the safety of the door body 210 opening process is improved.

[0083] In combination with the above-mentioned slot door structure for an electrolytic cell, the embodiment of the present disclosure provides a control method for the slot door structure, and the execution subject of the control method is a control device of the slot door structure, such as Figure 7 As shown, the control method includes:

[0084] S701, the control device detects whether the measuring mechanism reaches the measurement waiting position of the electrolytic cell.

[0085] Specifically, a monitoring sensor (eg, a pressure sensor) is provided at the measurement waiting position of the electrolytic cell, and the monitoring sensor is electrically connected to the control device. The control device can determine whether the measuring mechanism has reached the measurement waiting position of the electrolytic cell by acquiring monitoring data of the monitoring sensor.

[0086] S702, when the measuring mechanism reaches the measurement waiting position of the electrolytic cell, the control device controls the shell breaking assembly to perform a shell breaking operation on the furnace hole on the electrolytic cell.

[0087] Specifically, if the measuring mechanism reaches the measurement waiting position of the electrolytic cell, it indicates that the measuring mechanism is about to insert the measuring tool on it through the furnace hole into the electrolytic cell for sampling. In this case, if there is a crust on the furnace hole, it will affect the sampling of the measuring tool. Therefore, when the measuring mechanism reaches the measurement waiting position of the electrolytic cell, it will first control the shell breaking component to perform a shell breaking operation on the furnace hole on the electrolytic cell to remove the crust on the furnace hole.

[0088] S703, after the shelling is completed, the control device controls the driving mechanism to output power to drive the connecting rod assembly to pull the door body to rotate relative to the slot body so that the door body is opened, so that the measuring mechanism can perform sampling.

[0089] Specifically, after the shelling is completed, it can be confirmed that the measuring tool can be smoothly inserted through the furnace hole into the electrolytic cell for sampling. Therefore, in this case, the driving mechanism can be controlled to output power to drive the connecting rod assembly to pull the door body to rotate relative to the cell body to open the door body and expose the furnace hole, so that the measuring mechanism can control the corresponding measuring tool to perform sampling.

[0090] In the disclosed embodiment, when the measuring mechanism reaches the measurement waiting position corresponding to the electrolytic cell, the shell breaking assembly can be controlled to break the shell first, and then the door body can be controlled to open. In this way, the linkage control of the measuring mechanism and the slot door structure is realized, which can reduce the situation of manual shell breaking and manual door opening in a timely or inadequate manner, and improve the efficiency of the measuring mechanism.

[0091] The disclosed embodiment provides another control method for a slot door structure, such as Figure 8 As shown, the control method includes:

[0092] S801, the control device detects whether the measuring mechanism reaches the measurement waiting position of the electrolytic cell.

[0093] S802, when the measuring mechanism reaches the measurement waiting position of the electrolytic cell, the control device controls the shell breaking assembly to perform a shell breaking operation on the furnace hole on the electrolytic cell.

[0094] S803, after the shelling is completed, the control device controls the driving mechanism to output power to drive the connecting rod assembly to pull the door body to rotate relative to the slot body so that the door body opens.

[0095] S804, the control device receives feedback information on the type of measurement task and the type of identified furnace hole fed back by the measurement mechanism.

[0096] Specifically, according to the feedback information of the furnace hole type identified by the measuring mechanism, the current furnace hole condition can be determined, that is, whether there is still a crust that has not been cleaned up on the furnace hole. According to the type of measurement task fed back by the measuring mechanism, the type of measuring tool that needs to be inserted into the electrolytic cell through the furnace hole can be clearly identified. If the measuring tool is a measuring rod, the uncleaned crust can be ignored. If the measuring tool is a thermocouple, the uncleaned crust is likely to damage the thermocouple.

[0097] S805, when the measurement task type is the target task type and the furnace hole type is the target furnace hole type, the control device controls the shell breaking component to perform a shell breaking operation on the furnace hole again.

[0098] Specifically, if the measurement task type is the target task type, and the furnace hole type is the target furnace hole type, it indicates that the measurement task to be performed by the measurement mechanism is tank temperature measurement, the measurement tool to be used is a thermocouple, and there is currently an uncleaned crust in the furnace hole. In this case, if the measurement mechanism directly controls the thermocouple to be inserted into the electrolytic cell through the furnace hole, it is easy to cause damage to the thermocouple. Therefore, in this case, it is necessary to control the shelling component to perform the shelling operation on the furnace hole again.

[0099] In the disclosed embodiment, after the slot door is opened, the measuring mechanism will identify the type of furnace hole and determine the current measurement task to be performed, and based on this, generate feedback information to send to the control device. The control device determines whether it is necessary to control the shell breaking component to perform the shell breaking operation on the furnace hole again by analyzing the feedback information. In this way, the risk of damage to the measuring tool is reduced.

The shell structure for the electrolytic cell or the cell door structure for the electrolytic cell is installed on the cell body.

[0101] In the embodiments of the present disclosure, by providing a shell structure or a slot door structure as described above for the electrolytic cell on the cell body of the electrolytic cell, the degree of manual participation when the measuring mechanism automatically measures various parameters can be reduced, thereby improving the measuring efficiency of the measuring mechanism for various parameters of the electrolytic cell.
