Description

Technical Field

[0001] This utility model relates to the technical field of magnesium sacrificial anode experimental equipment, specifically to a magnesium sacrificial anode experimental device and system. Background Technology

[0002] Sacrificial anode corrosion technology is widely used due to its advantages such as economy, no management required, and no interference. The performance of the sacrificial anode is key to corrosion control and an important factor affecting the lifespan of the protected equipment. Magnesium sacrificial anodes, as an important anode material, have their electrochemical performance (including closed-circuit potential, open-circuit potential, and current efficiency) directly affecting their effectiveness. Currently, manufacturers generally use the constant current test method to test the performance, especially the electrochemical performance, of magnesium sacrificial anodes. For example, in Chinese invention patent CN110196223A, 'Experimental Method and Apparatus for Electrochemical Performance of Sacrificial Anodes under High Temperature Environment', the sealing cover used to seal the beaker in this experimental apparatus is not strong enough. After the thermometer, multiple salt bridges, and the anode sample are connected to the sealing cover, it is prone to deformation, leading to seal failure. Improvements are needed. Utility Model Content

[0003] One technical problem this application aims to solve is to overcome the deficiencies of the above-mentioned related technologies and provide a magnesium sacrificial anode experimental device and system, in which the experimental container is not prone to failure in sealing and is easy to assemble.

[0004] The technical solution adopted by this magnesium sacrificial anode experimental device to solve the technical problem is as follows: A magnesium sacrificial anode experimental device includes a tank body, a tank cover, a salt bridge and a calomel electrode, a magnesium sacrificial anode, a cathode terminal, and an anode terminal. The salt bridge, the calomel electrode, and the anode terminal are assembled on the tank cover. The magnesium sacrificial anode is connected to the anode terminal. A sealing ring is embedded in the top of the tank body. Multiple buckles are provided on the outer periphery of the tank cover and the tank body.

[0005] Compared with related technologies, this magnesium sacrificial anode experimental apparatus has the following advantages: a sealing ring is embedded in the top of the tank, which allows the tank cover to be made of hard metal material that is not easily deformed; the tank cover and the tank body are quickly fixed by multiple buckles on the outer periphery, making assembly convenient; users can quickly replace the magnesium sacrificial anode and change the liquid, and it can ensure that the experimental container is not easily damaged by seal failure.

[0006] As an improvement, two flat washers are fitted onto the anode terminal and screwed with two nuts. The washers are respectively attached to the upper and lower surfaces of the tank cover by the corresponding nuts, and the magnesium sacrificial anode is fixed to the bottom end of the anode terminal. The assembly of the anode terminal and the tank cover is relatively stable.

[0007] Furthermore, an elastic washer is provided between the upper flat washer and the upper nut. This makes the fixation of the anode terminal to the can lid more stable.

[0008] Preferably, the can lid is provided with at least one silicone plug, and the glass outer tube of the salt bridge and the calomel electrode is inserted into the silicone plug.

[0009] As an improvement, a digital temperature sensor is also included, which is mounted on the tank lid and whose probe is immersed in the electrolyte inside the tank. This digital and intelligent acquisition of temperature information reduces the workload of laboratory personnel.

[0011] The technical solution adopted by this magnesium sacrificial anode experimental system to solve the technical problem is as follows: A magnesium sacrificial anode experimental system includes a magnesium sacrificial anode experimental device, an electronic galvanometer, a monitoring device and a host computer, and also includes a base. The base has a row of assembly holes in the middle. The magnesium sacrificial anode experimental device is assembled in the assembly holes, and the electronic galvanometer is installed on the base and is located on both sides of the row of assembly holes.

[0012] Compared with related technologies, this magnesium sacrificial anode experimental system has the following advantages: It includes a base for centrally arranging the magnesium sacrificial anode experimental device and electronic galvanometer, and for limiting the movement of the magnesium sacrificial anode experimental device to prevent it from tipping over during setup; the magnesium sacrificial anode experimental device has a sealing ring embedded in the top of its tank, allowing the tank lid to be made of a hard metal material that is not easily deformed; the tank lid and tank body are quickly fixed together by multiple snaps on the outer periphery, making assembly convenient; users can quickly replace the magnesium sacrificial anode and perform liquid changes, and the system ensures that the experimental container seal is not easily compromised.
