Description

Technical Field

[0001] This utility model belongs to the field of electrolysis technology, specifically relating to a titanium anode strengthening life testing device. Background Technology

[0002] A titanium anode is an anode made primarily of titanium with a surface coating of metal oxide. Generally, electrode materials require good electrical conductivity, minimal electrode distance variation, strong corrosion resistance, good mechanical strength and processability, long lifespan, low cost, and excellent electrocatalytic performance for electrode reactions. Titanium is the metal that best meets all these comprehensive requirements.

[0003] For titanium anodes, service life is a crucial parameter for evaluating their performance. A longer service life reduces downtime, increases production efficiency, and lowers operating costs in actual production, making the company more competitive in the market. However, in actual production, the service life of titanium anodes is typically quite long, often exceeding several years. This makes rapid assessment and evaluation difficult. Currently, the main testing methods involve high current density electrolysis in a specially formulated electrolyte to evaluate the anode's lifespan under real-world operating conditions.

[0004] Chinese patent application CN118937197A discloses a titanium anode enhanced life testing device and its usage method. The test includes an electrolysis module with a first inlet at the lower end and a first outlet at the upper end. The first inlet is connected to a second outlet at the lower end of a sulfuric acid tank via a pipe, and the first outlet is connected to a second inlet at the upper end of the sulfuric acid tank via a pipe. The sulfuric acid tank is also connected to a pure water tank via a third inlet at its upper end. A water injection control device is also provided between the third inlet and the pure water tank. A constant temperature control system for controlling the temperature of the sulfuric acid solution in the sulfuric acid tank is also provided on the outside of the sulfuric acid tank. However, the testing range of the anode of this device is relatively limited, and it is only suitable for testing plate anodes of fixed size. Moreover, the electrode spacing of this device is constant, and it can only obtain life test data under a single electrode spacing, which cannot quickly determine whether the performance has degraded or failed. Summary of the Invention

[0005] To overcome the shortcomings of the prior art, the present invention aims to provide a titanium anode enhanced life testing device. Through a positioning mechanism located above the electrolytic container, the distance between the titanium anode and cathode can be flexibly adjusted, enabling more efficient location of failure causes, shorter analysis cycles, expanded testing dimensions, and acquisition of more comprehensive data, providing direct data support for optimizing product structure design. Furthermore, the device, through its open anode and cathode fixing method within the electrolytic module, is compatible with various titanium anode structures, expanding the testing range.

[0025] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0026] like Figure 1 As shown, a titanium anode enhanced life testing device is used to test titanium anodes of different shapes. It includes two electrolysis modules 1. Each electrolysis module 1 is connected to an electrolyte tank 2 through an external pipeline system 3, so that the electrolyte circulates between the electrolyte tank 3 and the electrolysis module 1. The electrolysis module 1 is electrically connected to a power supply 5 through a circuit connection system 4, which is used to supply power to the electrolysis module 1 to realize the operation of the device.

[0027] like Figure 2As shown, the electrolysis module 1 includes an electrolysis container 103 containing electrolyte. It is a cylindrical structure made of acid- and alkali-resistant, corrosion-resistant, and insulating polytetrafluoroethylene (PTFE) material. The top side wall of the electrolysis container 103 has an outlet 102, and the bottom side wall has an inlet 101. The top of the electrolysis container 103 is fitted with an electrolysis container cover 104. The cover 104 is also made of PTFE. A rectangular through-hole 116 is located in the center of the cover 104. A locking mechanism 115 is positioned around the rectangular through-hole 116 on the cover 104. The locking mechanism 115 has two cross-shaped fixing platforms 114 inside. The cross-shaped fixing platforms 114 are slidably connected to the locking mechanism 115, and each cross-shaped fixing platform 114 has an internally threaded through-hole at its center. Figure 3 As shown, the locking mechanism 115 includes two U-shaped grooves 117 spaced at the same distance as the short side of the rectangular through hole 116, one end of which is closed and the other end is open, and the openings of the two U-shaped grooves 117 are arranged opposite each other; two cross-shaped fixing platforms 114 are located between the two U-shaped grooves 117, and the two sides of the cross-shaped fixing platforms 114 are slidably connected to the inner groove walls of the two U-shaped grooves 117 respectively; one end of the rectangular through hole 116 extends to and beyond the open end of the U-shaped groove 117, so that the cross-shaped fixing platform 114 can be pulled out from the locking mechanism 115.

[0028] like Figure 2 and Figure 4 As shown, the electrolysis module 1 also includes an anode tube 108 and a cathode tube 111 that pass through the threaded through hole of the cross-shaped fixing platform 114 and extend into the electrolysis container 103. The outer sides of both tubes have external threads that match the threaded through hole of the cross-shaped fixing platform 114, so that the anode tube 108 and cathode tube 111 are threadedly connected to the cross-shaped fixing platform 114, fixing their vertical positions. Conductive rods 113 are respectively installed inside the anode tube 108 and cathode tube 111. One end of each conductive rod 113 extends out of the electrolysis container 103, bends vertically, and passes through openings on the side walls of the anode tube 108 and cathode tube 111, respectively, and connects to the copper core wires of the circuit connection system 4. The openings are positioned higher than the top of the locking mechanism 115. The bent part of the conductive rod 113 is aligned with the scale 112 on the positioning mechanism 115. It is first adjusted to the required spacing and then tightened by the fixing nuts 107 at both ends of the cross-shaped fixing platform 114. The two conductive rods 113 are respectively welded to the coating anode and coating cathode to be tested at one end inside the electrolytic container 103. The coating anode 109 and coating cathode 110 are arranged perpendicular to the ground and with the coating surfaces facing each other to ensure that the effective test area meets the test requirements and to prevent current density overload, accelerated coating failure, and distortion of test results.

[0029] The shapes of the coated anode 109 and coated cathode 110 include, but are not limited to, filamentous, plate-shaped, columnar, and mesh-shaped. When it is necessary to test the life of titanium anodes of other shapes, disconnect the electrical connection between the conductive rod 113 and the circuit connection system 4, unscrew the electrolytic container cover 104, loosen the fixing nuts 107 at both ends of the cross-shaped fixing platform 114, pull out the cross-shaped fixing platform 114 from the opening end of the locking mechanism 115, pull out the conductive rod 113 from the lower end of the anode tube 108 and the cathode tube 111, and replace it with a conductive rod 113 welded to anodes of other shapes. Repeat the above steps to fix it.

[0030] like Figure 2 As shown, the locking mechanism 115 has through holes 106 on both sides located on the electrolysis container cover 104. One through hole 106 is used for the electrolysis module temperature measuring device 207 to pass through so that it can extend into the electrolysis container 103 for temperature measurement. The other through hole 106 can also be used for liquid level observation, venting of electrolysis generated gas, and adding pure water.

[0031] like Figure 1 As shown, the electrolyte tank 2 contains electrolyte, and its top side wall has an inlet 201 and its bottom side wall has an outlet 202.

[0032] The testing device also includes a control panel 203 located on the side wall of the electrolyte tank 2, as well as an electrolyte tank temperature measuring device 205, an electrolyte tank heating device 206, and an electrolysis module temperature measuring device 207. The control panel 203 monitors the electrolyte circulation temperature of the entire device through the electrolyte tank temperature measuring device 205, the electrolyte tank heating device 206, and the electrolysis module temperature measuring device 207, and intervenes according to the set conditions to ensure that the electrolyte circulation temperature in the device is always within a suitable range. The temperature measuring probe of the electrolysis module temperature measuring device 207 extends into the electrolyte inside the electrolysis container 103 through the through hole 106 on the electrolysis container cover 104, and is placed near the anode. The signal output terminal of its temperature measuring probe is connected to the signal input terminal of the control panel 203 to transmit the measured temperature data to the control panel 203. The temperature measuring probe of the electrolyte tank temperature measuring device 205 extends into the electrolyte inside the electrolyte tank 2 through a through hole at the top of the electrolyte tank 2, and its signal output terminal is connected to the signal input terminal of the control panel 203. The heating head of the electrolyte tank heating device 206 extends into the electrolyte inside the electrolyte tank 2 through a through hole at the top of the electrolyte tank 2, and its signal input terminal is connected to the signal output terminal of the control panel 203. A rectangular liquid level observation window 204 is provided on the side wall of the electrolyte tank 2 for monitoring and observing the electrolyte inside the electrolyte tank 2.

[0033] like Figure 5As shown, the external piping system 3 includes an outlet pipe 301 connected to the outlet 202 of the electrolyte tank 2, and outlet pipes 305 and 306 connected to the inlets 101 of the two electrolysis modules 1. The outlet pipe 301 is connected to the inlet pipes 303 and 304 respectively via a transfer pump 308. The inlet pipes 303 and 304 are connected to the inlets 101 of the two electrolysis modules 1 respectively. The outlet pipe 301 is also equipped with a flow control valve 302. It can control and detect the flow rate of the entire device according to the different valve openings, and interfere with it according to the set conditions; the moving valve core of the flow control valve 302 extends into the interior of the electromagnetic coil 310 and adjusts the valve opening according to the strength of the energization; the second outlet pipe 305 and the third outlet pipe 306 are connected to the first inlet pipe 307 through the second delivery pump 309, and the first inlet pipe 307 is divided into two paths and connected to the outlets 102 of the two electrolysis modules 1 respectively. The above-mentioned external pipeline system 3 constitutes the electrolyte circulation path of the entire device.

[0034] The titanium anode strengthening life testing device may include one set of electrolysis modules 1 or multiple sets of electrolysis modules 1. The interfaces of the external pipeline system 3 adapted to two sets of electrolysis modules 1, namely the inlet pipe 2 303, inlet pipe 304, outlet pipe 2 305, outlet pipe 306, inlet pipe 1 307, and delivery pump 1 308 and delivery pump 2 309, are all quick connectors. The external pipeline system 3 can be quickly modified to adapt to the operation of different numbers of electrolysis modules 1 to meet different testing requirements.

[0035] The circuit connection system 4 includes a copper core wire. One end of the copper core wire is connected to two conductive rods 113 of the electrolysis module 1 through a connector 105, so that the current of the copper core wire is conducted to the conductive rods 113. The other end of the copper core wire is electrically connected to the power supply 5.

[0036] The working principle of the above-mentioned titanium anod strengthening life testing device is as follows: Prepare the electrolyte solution according to the specified ratio and pour it into the electrolyte tank 2 and the electrolysis container 103 respectively; cut the coated anode 109 and coated cathode 110 to appropriate sizes (e.g., titanium wire: Φ1.5mm / Φ3.0mm×30mm; plate: 20mm×20mm) and fix them to the lower end of the conductive rod 113; when the electrolyte in the device begins to circulate, turn on the power supply and record the energizing time to test its enhanced lifespan. After the current passes through the anode immersed in the electrolyte, gas is generated on the anode surface, and the gas reacts with the electrolyte to produce the product. However, the product yield is affected by a variety of factors, among which temperature and reactant flow rate are key control parameters, and their influence mechanism is as follows: Temperature directly affects product yield and purity by influencing reaction rate, reaction direction, and the extent of side reactions. Specifically, the effect of temperature on yield is a balance between "rate" and "side reactions." Low temperatures (<20℃): high yield (few side reactions), but slow rate and low output per unit time; high temperatures (>40℃): fast rate, but severe side reactions, low yield, and low output per unit time; optimal range: in industrial production, the temperature is usually controlled between 20-30℃, at which rate and yield are balanced, resulting in the highest product output. Furthermore, in continuous electrolysis, the electrolyte is often circulated by a pump, and the flow rate affects the uniformity of reactant mixing. Too low a flow rate: uneven solution mixing, locally low solution concentration, and potential "local excess" of gas leading to side reactions and reduced product yield; moderate flow rate: high turbulence, more thorough gas-solution contact, more complete reaction, and increased yield; too high a flow rate: while ensuring thorough mixing, it increases energy consumption and may cause uneven gas distribution due to equipment resistance, thus affecting efficiency. Therefore, it is essential to control the electrolyte circulation through temperature control modules, flow rate control modules, and other internal components of the device.

[0037] The method used for strengthening life testing of titanium anodes is as follows: Step 1: Use vises to cut the titanium wire anode to be tested into two short strips of titanium wire with a size of Φ1.5mm×30mm; one wire is used as the anode and the other is used as the cathode, and they are installed in the electrolysis module 1. Step 2: Prepare a solution with a conductivity of 1000 µs / cm using calcium chloride (CaCl2), magnesium sulfate heptahydrate (MgSO4·7H2O), and sodium bicarbonate (NaHCO3). 2 The electrolyte solution is poured into the electrolyte tank 2 and the electrolysis module 1 until the liquid level is above the liquid inlet 201 of the electrolyte tank 2 and the liquid outlet 102 of the electrolysis module 1. Step 3: Simultaneously turn on transfer pump 1 308 and transfer pump 2 309 to allow the electrolyte to start flowing inside the device; Step 4: Fix one end of the copper core wire to the tail of the connector 105 and clamp it onto the two conductive rods 113 of the electrolysis module 1 respectively; wrap the other end around the conductive post at the rear end of the power supply 5 and clamp it tightly. Step 5: Turn on power supply 5, set the current to 0.25A, constant current mode, and run the anode and cathode every half hour. Start timing and record the initial voltage; Step 6: When the voltage increases by 5V compared to the initial voltage, stop the timing, turn off the relevant devices, and stop operation.

Therefore, any modifications and changes made without departing from the scope of this utility model are within the scope of protection claimed by this utility model.
