Description

Technical Field

[0001] This utility model belongs to the field of anode material performance testing technology, specifically relating to a device for testing the performance of circulating water electrochemical anode materials. Background Technology

[0002] Electrochemistry of circulating water primarily studies the electrochemical processes occurring in circulating water systems (such as industrial circulating cooling water systems and central air conditioning circulating water systems). In these systems, water is continuously recycled and contains various dissolved ions (such as calcium, magnesium, iron, and chloride ions). When electrodes come into contact with the circulating water, redox reactions occur due to the differences in electrochemical properties between the electrode materials and the ions in the water. Oxidation occurs on the surface of the metal anode. Since the anode is a key component in the electrochemical reaction, its corrosion resistance significantly impacts the safety, service life, and performance stability of the equipment. In materials science, the corrosion performance of anode materials is typically assessed by testing their tolerance in specific corrosive environments. Existing testing methods usually employ single-point testing, requiring individual corrosion testing of each sample, resulting in low testing efficiency. Furthermore, some testing equipment is complex to operate when adjusting the sample position and testing height, easily leading to inaccurate sample positioning or uneven testing environments, thus affecting the accuracy and repeatability of the test results.

[0003] In anolyte testing equipment, simultaneous testing of multiple plates is key to improving efficiency. However, current technology still has shortcomings in the following aspects:

[0004] 1. Low efficiency of sample testing: Most existing equipment cannot test multiple samples at the same time, requiring repeated experiments, which is time-consuming and labor-intensive.

[0005] 2. Difficulty in achieving diversity in corrosive solution concentration: Some testing equipment cannot flexibly adjust or control the position of multiple samples in corrosive solutions of different concentrations, making it difficult to accurately compare the corrosion resistance of samples under different concentration conditions.

[0006] 3. Complex template position adjustment: The existing equipment has complicated template installation and height adjustment procedures, which may affect the test results and ease of operation of the template. Utility Model Content

[0007] In view of the problems existing in the prior art, the purpose of this utility model is to provide a performance testing device for electrochemical anode materials in circulating water. It can simultaneously test multiple samples, conveniently adjust the sample position and test height, and ensure effective control of liquid residue after the test, so as to improve testing efficiency and safety.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A device for testing the performance of electrochemical anode materials in circulating water includes a tank and an anode sample. The tank is hollow with an open top. A series of concave rings are uniformly formed on the outer surface of the tank. An annular track with a T-shaped cross-section is positioned above the outer surface of the tank. Multiple partition plates are uniformly arranged inside the tank, with their axes as the center, dividing the internal space into different regions. Sliding blocks are uniformly mounted on the surface of the annular track. The inner side of each sliding block has a groove adapted to the annular track. Sliding rods slide symmetrically through the surface of each sliding block, parallel to the tank axis. Top plates are positioned on the tops of two sliding rods. An extension plate is positioned on the side of the top plate facing the center of the tank. A suspension rope is connected to the lower end of the extension plate, and the anode sample is mounted at the bottom of the suspension rope. Bottom blocks are positioned at the bottoms of the two sliding rods, with mounting holes corresponding to the concave rings on their inner sides.

[0010] Furthermore, the extension plate has a notch at its end, the notch is open at its end, the suspension rope passes through the notch, and the top of the suspension rope has a conical head that is placed on the notch.

[0011] Furthermore, a clamping block is provided at the bottom of the suspension rope, and an installation groove is horizontally opened at the center of the bottom of the clamping block. The top of the anode template is installed in the installation groove at the bottom of the clamping block by bolts.

[0012] Furthermore, a connecting rod is slidably installed through the outer surface of the bottom block. The connecting rod is perpendicular to the axis of the pool body, and a wedge-shaped block is provided at one end of the connecting rod near the axis of the pool body.

[0013] Furthermore, the wedge block slides inside the mounting hole, the end of the wedge block is adapted to the internal size of the concave ring, and an extrusion slope is provided on the side of the upper surface of the wedge block near the axis of the pool body.

[0014] Furthermore, a spring is fitted onto the surface of the connecting rod, the spring is placed inside the mounting hole, and one end of the spring is in contact with the surface of the wedge block.

[0015] Furthermore, a pull plate is provided at the end of the connecting rod away from the wedge block, and the pull plate is placed on the outside of the bottom block.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention provides a device for testing the performance of electrochemical anode materials in circulating water. By setting up a pool and isolation plates, the interior of the pool is divided into multiple independent areas, each of which can be injected with corrosive liquids of different concentrations. This design enables the simultaneous testing of the corrosion resistance of multiple anode samples in different liquids within the same device, effectively improving testing efficiency. At the same time, the uniform distribution of the isolation plates ensures the independence of different testing environments and avoids cross-influence between corrosive liquids of different concentrations, thereby improving the accuracy of the test results.

[0018] This invention utilizes the cooperation of a sliding block and a ring track. The sliding block can slide along the surface of the ring track to adjust the relative distance between the anode samples. The sliding rod adjusts the immersion depth of the anode samples by sliding, allowing each anode sample to be flexibly positioned in the corrosive liquid. This design solves the problem of complex sample installation and position adjustment in the prior art, while improving the ease of operation and testing efficiency of the equipment.

[0019] This invention features a notch groove at the end of the extension plate, through which a suspension rope passes and is fixed by a conical head. This design facilitates the quick suspension and disassembly of the anode sample, reduces sample installation time, and improves the ease of use of the equipment. The clamping block fixes the anode sample with bolts, making the anode sample more stable during testing in corrosive liquids and avoiding testing errors caused by shaking.

[0020] This invention incorporates a wedge block, a spring, and a concave ring. The wedge block and the concave ring work together to achieve automatic limiting and precise adjustment of the height of the base block and the anode sample. The spring enables the wedge block to automatically reset, allowing the sample to be quickly lifted after the test, thus improving the safety and operational efficiency of the testing equipment.

A sliding block 2 is uniformly slidably mounted on the surface of the annular track 12, allowing the sliding block 2 to slide along the surface of the annular track 12 to adjust the position and angle of the sliding rod 3 and the anode sample 7.

[0030] The inner side of the slide block 2 is provided with a groove that matches the annular track 12; slide rods 3 slide symmetrically through the surface of the slide block 2, and the slide rods 3 are parallel to the axis of the pool body 1. The immersion depth of the anode sample 7 can be adjusted by moving the slide rods 3 up and down; a top plate 4 is provided on the top of the two slide rods 3, which serves as a support structure to fix the slide rods 3 and support the extension plate 5; an extension plate 5 is provided on the side of the top plate 4 facing the center of the pool body 1, which provides suspension support for the anode sample 7; a suspension rope 6 is connected to the lower end of the extension plate 5, which is used to connect and fix the position of the anode sample 7; the anode sample 7 is installed at the bottom of the suspension rope 6, and the anode sample 7 is fixed in the mounting groove at the bottom of the clamping block 62 by bolts to ensure that the anode sample 7 is stable during testing in the corrosive liquid; a base block 8 is provided at the bottom of the two slide rods 3, which makes the two slide rods 3 an integral structure to ensure stability during height adjustment.

[0031] refer to Figure 5As shown, the extension plate 5 has a notch 51 at its end, and the notch 51 is open at its end so that the lifting rope 6 can be quickly inserted and removed; the lifting rope 6 passes through the notch 51, and the top of the lifting rope 6 is provided with a conical head 61, which is placed on the notch 51. The conical head 61 fits the notch 51 by its shape to prevent the lifting rope 6 from falling off during operation.

[0032] refer to Figure 3 As shown, a clamping block 62 is provided at the bottom of the suspension rope 6; a mounting groove is horizontally opened at the bottom center of the clamping block 62, which is used to fix the anode sample 7; the top of the anode sample 7 is installed in the mounting groove at the bottom of the clamping block 62 by bolts. The tightening of the bolts ensures the stability of the anode sample 7 and prevents it from falling during the test.

[0033] refer to Figure 4 As shown, a connecting rod 9 is slidably installed through the outer surface of the bottom block 8; the connecting rod 9 is set perpendicular to the axis of the pool body 1, and the position of the wedge block 92 is adjusted by sliding it; a wedge block 92 is set at one end of the connecting rod 9 near the axis of the pool body 1, and the wedge block 92 acts as a limiting component, and realizes the height adjustment and positioning of the bottom block 8 by cooperating with the concave ring 11.

[0034] refer to Figure 4 As shown, the wedge block 92 slides inside the mounting hole 81; the end of the wedge block 92 is adapted to the internal size of the concave ring 11 to ensure the stability of the limit; a pressing slope 93 is provided on the side of the upper surface of the wedge block 92 near the axis of the pool body 1, and the pressing slope 93 can guide the wedge block 92 into or out of the concave ring 11 during the adjustment process.

[0035] refer to Figure 4 As shown, a spring 10 is sleeved on the surface of the connecting rod 9; the spring 10 is placed inside the mounting hole 81, and one end of the spring 10 is in contact with the surface of the wedge block 92, providing the reset elastic force of the wedge block 92; the presence of the spring 10 ensures that the wedge block 92 can automatically return to the corresponding concave ring 11 after adjustment, ensuring reliable limiting.

[0036] refer to Figure 4 As shown, a pull plate 91 is provided at the end of the connecting rod 9 away from the wedge block 92. The pull plate 91 is located outside the bottom block 8. The pull plate 91 is used to operate the connecting rod 9 to control the movement of the wedge block 92. The design of the pull plate 91 facilitates manual or mechanical operation and improves the convenience and safety of operation.

[0037] The working principle of this utility model is as follows: First, corrosive ionic liquids of different concentrations are injected into multiple different spaces inside the pool body 1. Then, the anode sample 7 to be measured is fixed to the bottom of the clamping block 62 with bolts, and the suspension rope 6 is fixed to the end of the extension plate 5 through the conical head 61. The notch 51 is an open structure, which facilitates the insertion of the suspension rope 6. The slide 2 can slide along the surface of the annular track 12 to adjust the distance between multiple anode samples 7 so that the anode sample 7 can enter the area between two adjacent isolation plates 13. By controlling the slide rod 3 to move down, the anode sample 7 can be immersed in the corrosive liquid. After a certain period of time, the corrosion of the material surface is observed, such as whether there are rust spots, pitting, etc. This device can simultaneously measure the corrosion resistance of multiple anode samples 7 in corrosive liquids of different concentrations, thus improving the comprehensive performance of corrosion resistance testing.

[0038] Because of the presence of spring 10, wedge block 92 always has a force toward the center of pool 1. When no force is applied, the end of wedge block 92 can enter the concave ring 11 at the corresponding height to limit the bottom block 8 and control the height of anode sample 7. At the same time, due to the presence of the extrusion slope 93, when the bottom block 8 is lifted, wedge block 92 will slide into the mounting hole 81 due to extrusion to ensure smooth lifting. Conversely, after the height adjustment is completed, the elastic force of spring 10 causes the end of wedge block 92 to automatically enter the corresponding concave ring 11 to achieve real-time limiting, thereby improving the convenience of operation. After the test, the anode sample 7 can be controlled to be higher than the liquid level so that the corrosion liquid on the surface of the anode sample 7 can be drained, preventing the corrosion liquid on the surface from falling outside the pool 1 and causing danger.

[0039] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
