Description

Technical Field

[0001] The present invention relates to the technical field of material resistance, and in particular to a device and method for testing the corrosion resistance of a sealing ring used for sealing an electrolytic cell. Background Art

[0002] As a key equipment, electrolytic cells are widely used in chemical industry, metallurgy, energy and other fields. The normal operation of electrolytic cells depends on good sealing performance. The sealing ring is the core component of the electrolytic cell sealing system. Its corrosion resistance is directly related to the service life of the electrolytic cell.

[0003] Currently, the traditional static immersion test method is often used to test the corrosion resistance of sealing rings used in electrolytic cell seals. This method involves placing the sealing ring in a specific corrosive medium and immersing it for a long time at room temperature and pressure. The corrosion resistance is evaluated by observing changes in the sealing ring's appearance and measuring changes in its dimensions and mechanical properties. A commonly used device is a constant temperature and humidity chamber. By applying this chamber to the corrosion resistance test of sealing rings used in electrolytic cell seals, it can simulate the high temperature and high humidity working environment of the electrolytic cell, making the test conditions more closely aligned with actual working conditions.

[0004] The constant temperature and humidity chamber currently used will cause the motor to be exposed to the air for a long time when used for a long time, and the long-term or overloaded operation of the motor will also cause the motor to heat up. In order to maintain good heat dissipation of the motor and avoid burning of its internal coil, the motor is generally placed naked to achieve good heat dissipation. Publication No. CN112564377B discloses a fully enclosed heat dissipation device for a machining machine motor, which includes a mounting seat, a heat dissipation box, a motor, a mounting frame, a turntable, a heat dissipation pipe and a heat absorption pipe; the heat dissipation box is a rectangular cavity structure with an open bottom, and the bottoms of the left and right side panels of the heat dissipation box are symmetrically fixed with fixed plates front and back, and each of the fixed plates is fixed to the mounting seat by fastening screws, and the motor is fixed to the upper surface of the mounting seat, and the motor is provided with a horizontal forward output shaft, and the output shaft is rotatably connected to the front side panel of the heat dissipation box and extends out of the heat dissipation box, and an active bevel gear is fixed to the output shaft outside the heat dissipation box, and the mounting frame is fixed to the outer wall of the right side panel of the heat dissipation box.

[0005] The constant temperature and humidity chamber heat dissipation device has the following shortcomings during specific use: it can only dissipate heat for motors of specific models, cannot meet the heat dissipation needs of motors of more models, and cannot meet the heat dissipation needs of the constant temperature and humidity chamber body. There are certain limitations in its use. At the same time, the closed heat dissipation will cause inconvenience to the maintenance and inspection of the internal motor; it uses wind energy to dissipate heat, but the heat dissipation effect is poor, and this heat dissipation method is greatly affected by the external temperature and has low practicality. It will also cooperate with water cooling, but the water in the water cooling will increase as the heat dissipation time progresses, and the heat dissipation effect will gradually weaken.

[0006] Therefore, a novel corrosion resistance testing device for sealing a sealing ring of an electrolytic cell can be used to solve the shortcomings of the prior art. Summary of the Invention

DETAILED DESCRIPTION

[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0051] Example 1: Reference Figure 1-Figure 5 、 Figure 9A corrosion resistance testing device for a sealing ring of an electrolytic cell, comprising a base plate 1, an outer cover 2 being fixedly mounted on the base plate 1, a plurality of sliding plates 12 being slidably mounted on the outer cover 2, two adjacent sliding plates 12 being fixedly connected by a linkage rod, a wind tube 28 being fixedly mounted on each sliding plate 12, a cooling fan 13 being rotatably mounted on each wind tube 28, a linkage mechanism being installed between the plurality of cooling fans 13, a heat conducting plate 4 being fixedly mounted on the outer cover 2 via a plurality of locking mechanisms, a plurality of fixed plates 7 being fixedly mounted on the heat conducting plate 4, and a plurality of magnets 8 being fixedly mounted on each fixed plate 7;

[0052] A folding protective plate 11 is fixedly installed between the upper and lower ends of each sliding plate 12 and the outer cover 2, thereby shielding the open part of the outer cover 2 and reducing the probability of dust entering.

[0053] The function of the cooling fan 13 is to heat the interior of the outer cover 2 and improve the working efficiency of the condenser 10 .

[0054] The heat conducting plate 4 is composed of many small heat conducting plates, and two adjacent heat conducting plates are rotatably connected. In order to facilitate observation of the heat conducting plates, the heat conducting plates are enlarged in this device and only part of the heat conducting plates are drawn.

[0055] The function of the magnet 8 is to adsorb the heat conducting plate 4 on the constant temperature and humidity chamber, without the need for bolts, making installation and disassembly more convenient, with low labor intensity and more convenient use. At the same time, the size of the heat conducting plate 4 can be adjusted according to the size of the constant temperature and humidity chamber, and is suitable for constant temperature and humidity chambers of different models.

[0056] The linkage mechanism includes a rotating rod 36, a rotating roller 37 and a crawler 38. Each cooling fan 13 is fixedly mounted with a rotating rod 36, and each rotating rod 36 is fixedly mounted with a rotating roller 37. A crawler 38 is commonly sleeved between the multiple rotating rollers 37.

[0057] The rotation of one of the cooling fans 13 will drive the rotating rod 36 on the cooling fan 13 to rotate, thereby driving the rotating roller 37 on the rotating rod 36 to rotate, and cooperate with the use of the track 38 to drive the other multiple rotating rollers 37 to rotate, thereby driving the other cooling fans 13 to rotate at the same time, achieving a linked effect.

[0058] The locking mechanism includes a locking block 18, a support block 19, a locking hook 20 and a pressure spring. A plurality of locking blocks 18 are fixedly mounted on the heat conducting plate 4, and a plurality of support blocks 19 are fixedly mounted on the outer cover 2.

[0059] Each support block 19 is slidably mounted with a locking hook 20 that cooperates with the corresponding locking block 18. A pressure spring is fixedly mounted between each locking hook 20 and the corresponding support block 19. Two adjacent locking hooks 20 are fixedly connected by a synchronization rod.

[0060] When installing the heat conducting plate 4, it is only necessary to align the locking block 18 with the locking hook 20, and then press the locking block 18 to engage the locking hook 20 to fix the heat conducting plate 4, thereby connecting the heat conducting plate 4 and the outer cover 2 as a whole for easy transportation.

[0061] Example 2: This example differs from the example 1 in that: Figure 2-Figure 4 、 Figure 6-Figure 7 、 Figure 9 A heat dissipation water tank 9 is fixedly mounted on the bottom plate 1, a servo motor 29 is fixedly mounted in the heat dissipation water tank 9, and a driving mechanism is installed between the servo motor 29 and one of the heat dissipation fans 13;

[0062] The drive mechanism includes a universal joint shaft 26 and a drive rod 27. The drive rod 27 is fixedly mounted on one driving end of the servo motor 29. The universal joint shaft 26 is mounted on the drive rod 27. The other end of the universal joint shaft 26 is fixedly connected to one of the cooling fans 13.

[0063] The rotation of one driving end of the servo motor 29 drives the driving rod 27 to rotate, and the rotation of the driving rod 27 drives the universal joint shaft 26 to rotate, thereby driving the cooling fan 13 connected to the universal joint shaft 26 to rotate;

[0064] Cooperating with the linkage mechanism, one servo motor 29 drives multiple cooling fans 13 to rotate, thereby reducing the driving source, improving the utilization rate of the servo motor 29, reducing energy consumption, and reducing production costs.

[0065] The universal joint shaft 26 is composed of two rotating rods and three universal joints.

[0066] Example 3: This example differs from the technical solution of Example 2 in that: Figure 4 、 Figure 6-Figure 7 、 Figure 9-10 , a lifting mechanism is installed between the servo motor 29 and one of the sliding plates 12;

[0067] The lifting mechanism comprises a reciprocating screw rod 22, a ball nut 41, and a connecting rod 42. The reciprocating screw rod 22 is rotatably mounted on the base plate 1, and a ball nut 41 is cooperatingly mounted on the reciprocating screw rod 22. The connecting rod 42 is fixedly mounted on the ball nut 41. The connecting rod 42 is fixedly connected to one of the sliding plates 12. A driving structure is installed between the drive rod 27 and the reciprocating screw rod 22.

[0068] The reciprocating screw 22 rotates to drive the ball nut 41 to move back and forth on the reciprocating screw 22, and the sliding plate 12 is driven up and down by the connecting rod 42 to achieve mobile heat dissipation, thereby dissipating heat at different positions in the outer cover 2, expanding the heat dissipation surface, and improving the heat dissipation efficiency.

[0069] A friction block is fixedly mounted on the connecting rod 42, and a friction rod matched with the friction block is fixedly mounted on the base plate 1. The friction between the friction block and the friction rod is used to offset the weight of the multiple sliding plates 12 and the multiple cooling fans 13, thereby preventing the ball nut 41 from automatically sliding under the action of gravity, thereby improving the stability of the operation between the ball nut 41 and the reciprocating screw 22.

[0070] The driving structure includes a support frame 17, a shaft 24, a gear 1 25, a gear 2, a bevel gear 1 39 and a bevel gear 2 40;

[0071] A support frame 17 is fixedly mounted on the bottom plate 1, a shaft 24 is rotatably mounted on the support frame 17, a gear 1 25 is fixedly mounted on one end of the shaft 24, and a gear 2 meshing with the gear 1 25 is fixedly mounted on the drive rod 27;

[0072] A helical gear 2 40 is fixedly mounted on the other end of the shaft 24, and a helical gear 1 39 meshing with the helical gear 2 40 is fixedly mounted on the reciprocating screw 1 22;

[0073] The driving rod 27 rotates to drive gear 2, and gear 2 drives gear 1 25 meshing with it to rotate, thereby driving the shaft 24 to rotate. The rotation of the shaft 24 drives the bevel gear 2 40 to rotate, thereby driving the bevel gear 1 39 meshing with the bevel gear 2 40 to rotate, thereby driving the reciprocating screw 1 22 to rotate, and cooperating with the above-mentioned lifting mechanism to achieve the purpose of moving the cooling fan 13 to dissipate heat.

[0074] Reference Figure 7-Figure 8 A condensation plate 30 is fixedly installed in the heat dissipation water tank 9, a condenser 10 is fixedly installed on the bottom plate 1, and the condenser 10 and the condensation plate 30 are connected through two condensation pipes 23. A fixed support plate 15 is fixedly installed on the heat dissipation water tank 9, a guide groove is opened in the heat conduction plate 4, and a plurality of telescopic tubes 21 connected to the guide groove are fixedly installed on the fixed support plate 15. A plurality of stirring mechanisms cooperating with the corresponding telescopic tubes 21 are installed on the heat dissipation water tank 9;

[0075] The condenser 10 is filled with coolant, and the condensation plate 30 absorbs heat from the water. The coolant in the condenser 10 evaporates when it encounters heat and flows back into the condenser 10 to cool and liquefy. This cycle is used to dissipate heat from the water in the heat dissipation water tank 9.

[0076] The stirring mechanism includes a diffuser 16, a stirring rod 32, turbine blades 33, a fixing frame 34 and a sealing ring 35;

[0077] The expansion tube 16 is fixedly mounted on the second telescopic tube 21 , a sealing ring 35 is fixedly mounted between the expansion tube 16 and the second telescopic tube 21 , a fixing frame 34 is fixedly mounted inside the expansion tube 16 , a stirring rod 32 is rotatably mounted on the fixing frame 34 , and a turbine blade 33 is fixedly mounted on the stirring rod 32 ;

[0078] Since the inner diameter of the expansion tube 16 is larger than the inner diameter of the telescopic tube 21, the water in the telescopic tube 21 will diverge after entering the expansion tube 16, and under the action of gravity, it will drive the turbine blades 33 to rotate, thereby driving the stirring rod 32 to stir the heat dissipation water tank 9, thereby accelerating the heat dissipation efficiency.

[0079] Reference Figure 1-Figure 2 、 Figure 7 、 Figure 11 A water injection box 31 is fixedly installed in the heat dissipation water tank 9, and a water injection mechanism is installed in the water injection box 31. A plurality of water injection pipes 14 are fixedly connected to the water injection box 31. A water outlet module 5 is fixedly installed on the plurality of water injection pipes 14. The water outlet module 5 is connected to the guide groove through a plurality of telescopic pipes 6.

[0080] The water injection mechanism includes a fixed ring 43, a support plate 44, a blocking plate 45, a return spring 46, a water inlet hole 47, a water baffle 48 and a push plate;

[0081] A push plate is slidably mounted in the water filling box 31, and a plurality of water inlet holes 47 are formed on the push plate. A plurality of receiving slots are also formed on the push plate, and a spring rod is fixedly mounted in each receiving slot. A water baffle 48 that matches the corresponding water inlet hole 47 is fixedly mounted on two matching spring rods.

[0082] When the push plate moves toward the side close to the water injection pipe 14, the water in the water injection tank 31 will be injected into the water outlet module 5 through the water injection pipe 14 (the water outlet module has a certain pressurization function to ensure that the water can smoothly enter the heat conduction plate 4). Then, the water will be injected into the guide groove in the heat conduction plate 4 through the telescopic pipe 1 6 through the water outlet module 5, and then returned to the heat dissipation water tank 9 through the telescopic pipe 2 21, realizing water circulation and heat dissipation.

[0083] When the push plate moves to the side away from the water injection pipe 14, the space in the water injection box 31 expands and the pressure decreases. At this time, the pressure will suck the water baffle 48 away from the water inlet hole 47. At this time, the water in the heat dissipation water tank 9 will enter the water injection box 31 through the water inlet hole 47. This process can be called the water absorption process. After the water absorption is completed, the spring rod will cause the water baffle 48 to abut against the water inlet hole 47 to block the water inlet hole 47.

[0084] The purpose of this part of the design is to circulate the water in the heat dissipation water tank 9 without using a water pump, thereby reducing costs, making one machine multi-purpose, and improving the utilization rate of the servo motor 29.

[0085] A pushing structure is installed between the push plate and the servo motor 29. A fixed ring 43 is fixedly installed in the water injection pipe 14. A support plate 44 is fixedly installed on the fixed ring 43. A plurality of return springs 46 are fixedly installed on the support plate 44. A blocking plate 45 that cooperates with the fixed ring 43 is fixedly installed on the plurality of return springs 46.

[0086] The pushing structure includes a reciprocating screw rod 2 49, a ball nut 2 and a rod sleeve. The rod sleeve is fixedly installed on the push plate, and the ball nut 2 is fixedly installed in the rod sleeve. The reciprocating screw rod 2 49 that cooperates with the ball nut 2 is fixedly installed on the other driving end of the servo motor 29;

[0087] The other driving end of the servo motor 29 rotates to drive the reciprocating screw rod 2 49 to rotate, so that the ball nut 2 drives the push plate to move in the water filling box 31, thereby realizing the reciprocating movement of the push plate;

[0088] When the push plate moves toward the side close to the water filling pipe 14, the water in the water filling tank 31 presses against the blocking plate 45 to separate the blocking plate 45 from the fixed ring 43, thereby completing the water discharge operation;

[0089] The push plate moves to the side away from the water injection pipe 14, and under the action of the return spring 46, the blocking plate 45 is again pressed against the fixed ring 43, thereby blocking the fixed ring 43;

[0090] This part is to prevent the water in the water injection pipe 14 from flowing back, ensuring the normal operation of the water circulation.

[0091] The specific operation steps of the present invention are:

[0092] The sealing ring is placed in a constant temperature and humidity chamber, into which corrosive electrolyte simulating the electrolytic cell environment is injected, and the temperature and humidity parameters are precisely controlled;

[0093] In the working condition simulation with the electrolytic cell operating temperature set at 80°C and humidity at 85% RH, the corrosion resistance and performance degradation of the sealing ring under the corresponding conditions were tested;

[0094] The heat conducting plate 4 is adsorbed on the constant temperature and humidity chamber by the magnetic force of the magnet 8;

[0095] The other driving end of the servo motor 29 rotates to drive the reciprocating screw rod 2 49 to rotate, so that the ball nut 2 drives the push plate to move in the water filling box 31, thereby realizing the reciprocating movement of the push plate;

[0096] When the push plate moves toward the side close to the water injection pipe 14, the water in the water injection tank 31 will be injected into the water outlet module 5 through the water injection pipe 14 (the water outlet module has a certain pressurization function to ensure that the water can smoothly enter the heat conduction plate 4). Then, the water will be injected into the guide groove in the heat conduction plate 4 through the telescopic pipe 1 6 through the water outlet module 5, and then returned to the heat dissipation water tank 9 through the telescopic pipe 2 21, realizing water circulation and heat dissipation.

[0097] When the push plate moves to the side away from the water injection pipe 14, the space in the water injection box 31 expands and the pressure decreases. At this time, the pressure will suck the water baffle 48 away from the water inlet hole 47. At this time, the water in the heat dissipation water tank 9 will enter the water injection box 31 through the water inlet hole 47. This process can be called the water absorption process. After the water absorption is completed, the spring rod will cause the water baffle 48 to abut against the water inlet hole 47 to block the water inlet hole 47.

[0098] When the push plate moves toward the side close to the water filling pipe 14, the water in the water filling tank 31 presses against the blocking plate 45 to separate the blocking plate 45 from the fixed ring 43, thereby completing the water discharge operation;

[0099] The push plate moves away from the water injection pipe 14, and under the action of the return spring 46, the blocking plate 45 is again pressed against the fixed ring 43, thereby blocking the fixed ring 43 and preventing the water in the water injection pipe 14 from flowing back.

[0100] Since the inner diameter of the expansion tube 16 is larger than that of the second telescopic tube 21, the water in the second telescopic tube 21 will disperse after entering the expansion tube 16. Under the action of gravity, the turbine blades 33 will rotate, thereby driving the stirring rod 32 to stir the heat dissipation water tank 9, thereby accelerating the heat dissipation efficiency.

[0101] The driving rod 27 rotates to drive the gear 2, which drives the gear 1 25 meshing with it to rotate, thereby driving the shaft 24 to rotate, and the rotation of the shaft 24 drives the bevel gear 2 40 to rotate, thereby driving the bevel gear 1 39 meshing with the bevel gear 2 40 to rotate, thereby driving the reciprocating screw 1 22 to rotate;

[0102] The reciprocating screw rod 22 rotates to drive the ball nut 41 to move back and forth on the reciprocating screw rod 22, and the connecting rod 42 drives the sliding plate 12 to move up and down to achieve mobile heat dissipation;

[0103] A friction block is fixedly mounted on the connecting rod 42, and a friction rod that cooperates with the friction block is fixedly mounted on the base plate 1. The friction between the friction block and the friction rod is used to offset the weight of the multiple sliding plates 12 and the multiple cooling fans 13, thereby preventing the ball nut 1 41 from automatically sliding under the action of gravity, thereby improving the stability of the operation between the ball nut 1 41 and the reciprocating screw 1 22;

[0104] The rotation of one driving end of the servo motor 29 drives the driving rod 27 to rotate, and the rotation of the driving rod 27 drives the universal joint shaft 26 to rotate, thereby driving the cooling fan 13 connected to the universal joint shaft 26 to rotate;

[0105] The rotation of one of the cooling fans 13 drives the rotating rod 36 on the cooling fan 13 to rotate, thereby driving the rotating roller 37 on the rotating rod 36 to rotate. The use of the crawler 38 drives the other rollers 37 to rotate, thereby driving the other cooling fans 13 to rotate simultaneously, achieving a linked effect.

[0106] The condenser 10 is filled with coolant, and the condensation plate 30 absorbs heat from the water. The coolant in the condenser 10 evaporates when it encounters heat and flows back to the condenser 10 through the condenser tube 23 to cool and liquefy. This cycle is used to dissipate heat from the water in the heat dissipation water tank 9.

[0107] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
