Description

Technical Field

[0001] This invention belongs to the technical field of electrolytic cell power supply control equipment, and specifically relates to an intelligent monitoring device for electrolytic cells. Background Technology

[0002] Electrolytic cells are core equipment in the non-ferrous metal smelting industry and are widely used in nickel-cobalt smelting, hydrogen production and other fields. When operating in clusters, they mostly adopt a series power supply mode, and require a horizontal switch to realize the independent on-off control of one or more electrolytic cells in order to complete the loading and unloading operations of the electrolytic cells. The existing technology suffers from the following key defects: 1. Low level of intelligence: Traditional non-ferrous metal smelting industries rely heavily on manual operation for their electrolytic cell horizontal switching devices. This makes them unable to respond to grid load fluctuations and changes in electrolytic cell operating status. In the coordinated control of multiple electrolytic cells, there is a response lag, and real-time status monitoring is lacking, making it difficult to predict faults such as contact wear or poor contact, and short circuits between the anode and cathode of the electrolytic cell. 2. Significant arc hazards: The electrode contacts of traditional horizontal switching devices are prone to arcing during switching processes. High temperatures can burn the contacts and insulation layers, and even cause phase-to-phase short circuits and equipment explosions, seriously threatening personnel and equipment safety. Although oil-cooled arc extinguishing technology is used, it lacks dynamic adjustment capabilities, and the arc extinguishing efficiency is greatly affected by operating conditions. 3. High operation and maintenance costs: Traditional horizontal switching devices are susceptible to corrosion from acidic gases and liquids in the field, requiring regular manual cleaning and maintenance. The switch casing is often a one-piece structure with complex internal mechanical structures, making disassembly difficult. Therefore, developing an intelligent monitoring device for electrolytic cells that combines intelligent control, reliable arc extinguishing, and fault early warning functions is crucial to solving the above technical problems. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned problems by providing an intelligent monitoring device for electrolytic cells.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an intelligent monitoring device for an electrolytic cell, comprising an insulating shell, a moving horizontal electric block assembly disposed inside the insulating shell, a stationary horizontal electric block assembly disposed below the moving horizontal electric block assembly, the end of the stationary horizontal electric block assembly axially penetrating the insulating shell to the outside from the end away from the moving horizontal electric block assembly, a DC traction electromagnetic structure disposed above the moving horizontal electric block assembly that enables the moving horizontal electric block assembly to move axially up and down along the direction of the stationary horizontal electric block assembly, an arc contact assembly disposed between the moving horizontal electric block assembly and the stationary horizontal electric block assembly, and an intelligent monitoring mechanism disposed at the upper end of the insulating shell that is connected to the DC traction electromagnetic structure, the moving horizontal electric block assembly and the stationary horizontal electric block assembly respectively.

[0005] In the aforementioned intelligent monitoring device for an electrolytic cell, the insulating shell comprises two upper and lower insulating outer shells, with a sealing strip between them and secured by a locking buckle. A transparent protective cover is located on the outer side of the upper insulating outer shell, and a sealing strip is provided between the transparent protective cover and the insulating outer shell. The insulating shell is made of a high-polymer composite material and lined with a steel plate. It adopts an upper and lower split structure and is secured by locking buckles, abandoning the traditional one-piece casting or long-term bolt fixing method. This makes the inspection, maintenance, and replacement of internal components extremely convenient, eliminating the need for complete disassembly and significantly reducing downtime. The sealing strip forms a sealing barrier, effectively preventing highly corrosive gases and dust from entering the shell, significantly improving the service life and insulation reliability of the device in harsh industrial environments.

[0006] In the aforementioned intelligent monitoring device for an electrolytic cell, the DC traction electromagnetic structure includes a vertically arranged electromagnet. The upper end of the electromagnet is provided with a top fixing plate connected to the middle of the upper end of an insulating shell. A stainless steel push rod with both ends axially penetrating the electromagnet is provided on the inner circumference of the electromagnet. The upper end of the stainless steel push rod axially penetrates the insulating shell, and a top push rod safety lock corresponding to the stainless steel push rod is provided at the middle of the upper end of the insulating shell. When the electromagnet is energized, the coil attracts and quickly drives the stainless steel push rod to press down and close the circuit. After power is cut off, the stainless steel push rod quickly resets and opens the circuit. The top push rod safety lock is manually closed when the electromagnet is energized and attracted, preventing the stainless steel push rod from rebounding when the device loses power.

[0007] In the aforementioned intelligent monitoring device for an electrolytic cell, the moving horizontal electric block assembly includes a horizontal electric block support plate disposed at the lower end of the electromagnet, a moving conductive block disposed on the lower side of the horizontal electric block support plate, the length of the horizontal electric block support plate being greater than the length of the moving conductive block, a plurality of connecting screws connected to the horizontal electric block support plate being disposed circumferentially on the moving conductive block, a moving conductive block compression spring disposed on the outer side of the connecting screws and located between the horizontal electric block support plate and the moving conductive block, the lower end of the stainless steel push rod axially penetrating the horizontal electric block support plate and the moving conductive block in sequence, and a moving conductive block limiting nut connected to the lower end of the stainless steel push rod being disposed below the moving conductive block. The limiting nut of the moving conductive block facilitates the adjustment of the opening distance and pressure of the moving conductive block. The moving conductive block is not rigidly fixed to the horizontal conductive block support plate, but is floatingly connected through a connecting screw and a compression spring of the moving conductive block. This design allows the moving conductive block to automatically adjust its posture according to the microscopic unevenness of the contact surface when it presses down to contact the stationary conductive block, ensuring maximum contact area and effectively reducing contact resistance and heat generation. The compression spring of the moving conductive block not only provides cushioning, but more importantly, it continuously applies stable contact pressure in the closed state. Even if the conductive block is slightly thermally expanded or vibrated due to a large current impact, the contact pressure can be kept stable, preventing contact bounce and welding.

[0008] In the aforementioned intelligent monitoring device for an electrolytic cell, the static conductive block assembly includes two static conductive blocks positioned on either side below the moving conductive block. These static conductive blocks are fixedly connected to the bottom of an insulating housing via bolts. One end of each static conductive block extends axially through the outside of the insulating housing, while the other end is located below one side of the moving conductive block. The lower end of the insulating housing has outlet holes on both sides for the static conductive blocks to pass through, and the outlet holes have pressure-relief sealing strips that contact the static conductive blocks. The pressure-relief sealing strips are tightly fitted to the static conductive blocks, and can open to release pressure when the internal pressure of the insulating housing exceeds a certain value.

[0009] In the aforementioned intelligent monitoring device for an electrolytic cell, the arc contact assembly includes stationary arc contacts respectively disposed on the same side of one adjacent end of two stationary conductive blocks. The stationary arc contacts are connected to the stationary conductive blocks via several connecting bolts. One end of the moving conductive block is provided with a moving arc contact corresponding to the stationary arc contact. The side of the moving arc contact away from the stationary arc contact is connected to a horizontal conductive block support plate via several contact connecting rods. The upper end of each contact connecting rod is provided with an arc contact limiting nut that contacts the horizontal conductive block support plate. Furthermore, an arc contact compression spring is provided circumferentially outside the contact connecting rod, located between the horizontal conductive block support plate and the moving arc contact. The arc contact limiting nut facilitates adjustment of the opening distance and pressure of the moving arc contact.

[0010] In the aforementioned intelligent monitoring device for an electrolytic cell, the stationary arc contact has a stationary contact piece on the side near the moving arc contact, and the moving arc contact has moving contact pieces corresponding to the stationary contact pieces at both ends on the side near the stationary arc contact. Both the stationary and moving contact pieces are made of high-melting-point pure tungsten. The use of high-melting-point pure tungsten for both the stationary and moving contact pieces greatly improves the contact's resistance to arc erosion and welding, significantly extending the electrical life of the arc contact.

[0011] In the aforementioned intelligent monitoring device for an electrolytic cell, the lower side of the moving arc contact is lower than the lower side of the moving conductive block, and the upper side of the stationary arc contact is higher than the upper side of the stationary conductive block. During closing, the moving and stationary arc contacts make contact before the moving and stationary conductive blocks; during opening, the moving and stationary arc contacts separate before the moving and stationary conductive blocks. This timing perfectly guides the pre-breakdown arc during closing and the breaking arc during opening to the dedicated arc contacts, protecting the conductive blocks from arc erosion.

[0012] In the aforementioned intelligent monitoring device for an electrolytic cell, a DC voltage monitor is provided at one end adjacent to the stationary conductive block and on the side away from the stationary arc contact, and a screw-type thermal resistor is provided on one side of the moving conductive block. The DC voltage monitor is used to monitor the DC voltage of the electrolytic cell on both sides of the horizontal electric switch, and the screw-type thermal resistor is used to monitor the temperature of the horizontal electric block inside the insulating shell.

[0013] In the aforementioned intelligent monitoring device for an electrolytic cell, the intelligent monitoring mechanism includes a self-locking start button located on the upper end of the insulating shell and connected to an electromagnet. One side of the self-locking start button is equipped with a digital display thermometer connected to a screw-type resistance thermometer, and the other side is equipped with a digital display DC voltmeter connected to a DC voltage monitor. An alarm buzzer is also located on the upper end of the insulating shell. The self-locking start button can locally activate the transverse switch; upon activation, the button illuminates a green indicator light. The alarm buzzer emits a beeping sound to indicate a malfunction. The digital display thermometer displays the temperature of the transverse switch inside the insulating shell in real time; an alarm signal is output when the temperature is too high. The digital display DC voltmeter displays the DC voltage of the electrolytic cell in real time; an alarm signal is output when the voltage is too low.

[0014] Compared with existing technologies, the advantages of this invention are:

[0015] 1. This device solves the problems of low intelligence level, serious electric arc hazard, and complex operation and maintenance of traditional electrolytic cell horizontal power switches. It has advantages such as good arc extinguishing effect, fast response speed, stable operation and low maintenance cost. At the same time, it can alarm and quickly close the horizontal power switch at the first time when the anode and cathode of the electrolytic cell are short-circuited, so as to ensure production safety and extend the service life of the equipment.

[0016] 2. The device adopts a split insulating shell and sealing strip design, which has strong overall insulation performance and can effectively prevent leakage, short circuit and arc overflow, meeting the safety requirements for use in high voltage and strong corrosion conditions such as electrolytic cells.

[0017] 3. The device has a built-in DC voltage monitor and screw-type resistance temperature detector. Together with a digital voltmeter and a digital thermometer, it can monitor the voltage and contact temperature of the electrolytic cell circuit in real time, and intuitively reflect the operating status of the device.

[0018] 4. This device is equipped with an alarm buzzer, which can promptly sound and light alarms when there are faults such as abnormal temperature, excessive voltage fluctuations, or poor contact, making it easier for maintenance personnel to quickly identify potential problems and prevent the electrolytic cell fault from escalating.

[0019] 5. This device uses a DC traction electromagnet in conjunction with a stainless steel push rod for drive. It has stable operation and controllable stroke, and can realize the rapid connection and disconnection of moving and stationary conductive blocks. It has high control precision and is suitable for frequent start-up and shutdown and protection of electrolytic cell loads.

[0020] 6. Both the moving conductive block and the moving arc contact of this device are equipped with compression springs, which can provide stable contact pressure, reduce the vibration generated when the device is engaged, make the moving and stationary conductive blocks fit more tightly, and improve the stability of energization.

[0021] 7. The moving and stationary arc contacts of this device are made of high-melting-point pure tungsten material, and the lower side of the moving arc contact is lower than the lower side of the moving conductive block, while the upper side of the stationary arc contact is higher than the upper side of the stationary conductive block. This allows the arc contact components to be closed and then opened relative to the moving and stationary conductive blocks, which greatly reduces the probability and duration of arc generation, reduces contact burn-out, and extends the service life of the switch.

Detailed Implementation

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0027] like Figure 1-3 As shown, an intelligent monitoring device for an electrolytic cell includes an insulating shell 1. A moving horizontal electric block assembly 2 is provided inside the insulating shell 1. A stationary horizontal electric block assembly 3 is provided below the moving horizontal electric block assembly 2. The end of the stationary horizontal electric block assembly 3 away from the moving horizontal electric block assembly 2 axially penetrates the insulating shell 1 to the outside. A DC traction electromagnetic structure 4 is provided above the moving horizontal electric block assembly 2, which can make the moving horizontal electric block assembly 2 move axially up and down along the direction of the stationary horizontal electric block assembly 3. An arc contact assembly 5 is provided between the moving horizontal electric block assembly 2 and the stationary horizontal electric block assembly 3. An intelligent monitoring mechanism 6 is provided at the upper end of the insulating shell 1, which is connected to the DC traction electromagnetic structure 4, the moving horizontal electric block assembly 2 and the stationary horizontal electric block assembly 3 respectively.

[0028] like Figure 1As shown, the insulating housing 1 has two insulating outer shells 11 arranged vertically. A sealing strip is provided between the two insulating outer shells 11, and they are fixed together by a locking buckle 12. A transparent protective cover 13 is provided on the outer side of the upper insulating outer shell 11, and a protective cover sealing strip 14 is provided between the transparent protective cover 13 and the insulating outer shell 11. The insulating outer shell 11 is made of high-polymer composite material and lined with a steel plate. It adopts a split-type structure and is fixed by the locking buckle 12, abandoning the traditional one-piece casting or long-term bolt fixing method. This makes the inspection, maintenance, and replacement of internal components extremely convenient, without the need for complete disassembly, greatly shortening downtime. The sealing strip forms a sealing barrier, effectively preventing highly corrosive gases and dust from entering the housing, significantly improving the service life and insulation reliability of the device in harsh industrial environments.

[0029] Combination Figure 1 and Figure 2 As shown, the DC traction electromagnetic structure 4 includes a vertically arranged electromagnet 41. The upper end of the electromagnet 41 is provided with a top fixing plate 42 connected to the middle of the upper end of the insulating housing 1. A stainless steel push rod 43 with both ends axially penetrating the electromagnet 41 is provided on the inner circumference of the electromagnet 41. The upper end of the stainless steel push rod 43 axially penetrates the insulating housing 1, and a top push rod safety lock 44 corresponding to the stainless steel push rod 43 is provided at the middle of the upper end of the insulating housing 1. When the electromagnet 41 is energized, the coil attracts and quickly drives the stainless steel push rod 43 to press down and close the circuit. After de-energization, the stainless steel push rod 43 quickly resets and opens the circuit. The top push rod safety lock 44 is manually closed when the electromagnet 41 is energized and attracted, preventing the stainless steel push rod 43 from rebounding when the device loses power.

[0030] Combination Figure 2 and Figure 3As shown, the moving horizontal electric block assembly 2 includes a horizontal electric block support plate 21 disposed at the lower end of the electromagnet 41. A moving conductive block 22 is disposed on the lower side of the horizontal electric block support plate 21. The length of the horizontal electric block support plate 21 is greater than the length of the moving conductive block 22. The moving conductive block 22 is provided with a plurality of connecting screws 23 connected to the horizontal electric block support plate 21 in the circumferential direction. A moving conductive block compression spring 24 is sleeved on the outer side of the connecting screws 23 and located between the horizontal electric block support plate 21 and the moving conductive block 22. The lower end of the stainless steel push rod 43 passes through the horizontal electric block support plate 21 and the moving conductive block 22 in sequence in the axial direction. A moving conductive block limiting nut 25 connected to the lower end of the stainless steel push rod 43 is disposed below the moving conductive block 22. The moving conductive block limiting nut 25 facilitates the adjustment of the opening distance and pressure of the moving conductive block 22. The moving conductive block 22 is not rigidly fixed on the horizontal conductive block support plate 21, but is floated by the connecting screw 23 and the moving conductive block compression spring 24. This design allows the moving conductive block 22 to automatically adjust its posture according to the micro-unevenness of the contact surface when it presses down to contact the stationary conductive block 31, ensuring the maximum contact area and effectively reducing contact resistance and heat generation. The moving conductive block compression spring 24 not only provides buffering, but more importantly, it continuously applies stable contact pressure in the closed state. Even if the conductive block is slightly thermally expanded or vibrated due to a large current impact, the contact pressure can be kept stable, preventing contact bounce and welding.

[0031] The static conductive block assembly 3 includes two static conductive blocks 31 positioned on either side below the moving conductive block 22. The static conductive blocks 31 are fixedly connected to the bottom of the insulating housing 1 by fixing bolts. One end of each static conductive block 31 extends axially through the outside of the insulating housing 1, while the other end is located below one side of the moving conductive block 22. The lower end of the insulating housing 1 has outlet holes on both sides for the static conductive blocks 31 to pass through. A pressure relief sealing strip 32, in contact with the static conductive block 31, is provided on the inner circumferential side of each outlet hole. The pressure relief sealing strip 32 is tightly fitted to the static conductive block 31, and can open to release pressure when the internal pressure of the insulating housing 1 exceeds a certain value.

[0032] Specifically, the arc contact assembly 5 includes stationary arc contacts 51 respectively disposed on the same side of one of the adjacent ends of two stationary conductive blocks 31. The stationary arc contacts 51 are connected to the stationary conductive blocks 31 by several connecting bolts 52. One end of the moving conductive block 22 is provided with a moving arc contact 53 corresponding to the stationary arc contact 51. The side of the moving arc contact 53 away from the stationary arc contact 51 is connected to the horizontal conductive block support plate 21 by several contact connecting rods 54. The upper end of the contact connecting rod 54 is provided with an arc contact limiting nut 55 that contacts the horizontal conductive block support plate 21, and an arc contact compression spring 56 is provided on the outer circumference of the contact connecting rod 54 between the horizontal conductive block support plate 21 and the moving arc contact 53. The arc contact limiting nut 55 facilitates the adjustment of the opening distance and pressure of the moving arc contact 53.

[0033] Furthermore, the stationary arc contact 51 has a stationary contact piece 57 on the side near the moving arc contact 53, and the moving arc contact 53 has moving contact pieces 58 at both ends on the side near the stationary arc contact 51, corresponding to the stationary contact piece 57. Both the stationary contact piece 57 and the moving contact piece 58 are high-melting-point pure tungsten contact pieces. The use of high-melting-point pure tungsten for the stationary contact piece 57 and the moving contact piece 58 greatly improves the contact's resistance to arc erosion and resistance to welding, and significantly extends the electrical life of the arc contact.

[0034] Furthermore, the lower side of the moving arc contact 53 is lower than the lower side of the moving conductive block 22, and the upper side of the stationary arc contact 51 is higher than the upper side of the stationary conductive block 31. During closing, the moving arc contact 53 and the stationary arc contact 51 contact before the moving conductive block 22 and the stationary conductive block 31. During opening, the moving arc contact 53 and the stationary arc contact 51 separate before the moving conductive block 22 and the stationary conductive block 31. This timing perfectly guides the pre-breakdown arc during closing and the breaking arc during opening to the dedicated arc contact, protecting the conductive blocks from arc erosion.

[0035] Meanwhile, a DC voltage monitor 33 is provided at one end of the stationary conductive block 31, away from the stationary arc contact 51, and a screw-type thermal resistor 26 is provided on one side of the moving conductive block 22. The DC voltage monitor 33 is used to monitor the DC voltage of the electrolytic cells on both sides of the horizontal electric switch, and the screw-type thermal resistor 26 is used to monitor the temperature of the horizontal electric block inside the insulating housing 1.

[0036] like Figure 1 As shown, the intelligent monitoring mechanism 6 includes a self-locking start button 61 located on the upper end of the insulating housing 1 and connected to the electromagnet 41. On one side of the self-locking start button 61 is a digital display temperature gauge 62 connected to the screw-type thermal resistor 26, and on the other side is a digital display DC voltmeter 63 connected to the DC voltage monitor 33. An alarm buzzer 64 is also located on the upper end of the insulating housing 1. The self-locking start button 61 can locally activate the transverse switch; when activated, the button illuminates a green indicator light. The alarm buzzer 64 will emit a buzzing sound to alert the system in case of a malfunction. The digital display temperature gauge 62 displays the temperature of the transverse block inside the insulating housing 1 in real time; an alarm signal will be output when the temperature is too high. The digital display DC voltmeter 63 displays the DC voltage of the electrolytic cell in real time; an alarm signal will be output when the voltage is too low.

[0037] The principle of this embodiment is as follows:

[0038] When closing the circuit, the self-locking start button 61 is pressed, and the electromagnet 41 is energized and quickly drives the stainless steel push rod 43 to push down a certain distance. At the same time, the stainless steel push rod 43 drives the horizontal electric block support plate 21 to push down, so that the moving conductive block 22 and the moving arc contact 53 connected to the horizontal electric block support plate 21 move towards the stationary conductive block 31 and the stationary arc contact 51 respectively to close the circuit. The moving conductive block 22 and the moving arc contact 53 compress the moving conductive block compression spring 24 and the arc contact compression spring 56 respectively to complete the closing action. When opening the circuit, the self-locking start button 61 is pressed to reset, and the electromagnet 41 is de-energized. The stainless steel push rod 43 quickly resets, and the moving conductive block 22 and the moving arc contact 53 also quickly reset, completing the tripping action. After the device enters the working state, the screw-type thermal resistor 26 installed on the moving conductive block 22 collects the temperature of the conductive block in real time and transmits the signal to the digital display temperature meter 62 for display. The DC voltage monitor 33 installed on the stationary conductive block 31 collects the DC voltage of the circuit in real time and displays it on the digital display DC voltage meter 63. When the temperature or voltage exceeds the set safety range, the alarm buzzer 64 immediately emits an audible and visual alarm to remind the operator to handle it in time.
