Description

Technical Field

[0001] The utility model relates to the technical field of CO2 detection, in particular to an anode CO2 reactivity measuring instrument with a ceramic inner liner and a ventilation pipe. Background Technique

[0002] An anode refers to the electrode connected to the positive pole of the power supply in an electrolytic cell. Anodic oxidation means that a workpiece made of a certain metal (mainly aluminum) is used as the anode, and electrolysis is carried out in a suitable electrolyte to form an inorganic oxide film on the surface of the workpiece. The metal oxide film has properties such as corrosion resistance, wear resistance, and insulation, and can be used as a protective layer for metals or the bottom layer of paint. The oxide film can also adsorb a variety of organic and inorganic dyes, making the surface of metal products present bright colors and playing a decorative role. Non-ferrous metals such as aluminum and magnesium and their alloys can all be subjected to anodic oxidation treatment. The oxide film of aluminum has the best corrosion resistance and is widely used in the surface treatment of parts of airplanes, automobiles, electronic appliances, instruments, daily necessities, handicrafts, etc. When the anode reacts, gas is usually produced, and an anode CO2 reactivity measuring instrument is needed to detect CO2 in the gas. However, the existing measuring instruments are not convenient for the installation and replacement of the anode during use. Moreover, since the density of CO2 is greater than that of air, CO2 will be located at the bottom of the gas, which is not convenient for subsequent detection. Therefore, we have proposed an anode CO2 reactivity measuring instrument with a ceramic inner liner and a ventilation pipe. Content of the Utility Model

[0008] Furthermore, limiting strips are uniformly arranged on the inner wall of the housing, and grooves slidably connected to the limiting strips are uniformly arranged on the outer side of the ceramic inner liner to play a role in limiting the ceramic inner liner.

[0009] Furthermore, rotating rings are provided on both the inner arc surface and the outer arc surface at the lower opening of the annular groove, and blades are uniformly arranged between the two rotating rings to play a role in guiding the gas.

[0010] Furthermore, a motor is provided on the upper surface of the top cover. The lower end of the output shaft of the motor is provided with a gear, and the gear is located in the notch on the bottom surface of the top cover. The gear is meshed and connected with the teeth uniformly arranged on the outer arc surface of the outer rotating ring.

[0013] Furthermore, sealing rings contacting the anode rod are uniformly arranged on the inner wall of the lower opening of the installation cylinder to ensure the sealing performance between the anode rod and the lower end of the installation cylinder.

Elastic clamping plates 21 are provided in the openings evenly arranged at the lower end of the outer arc surface of the installation cylinder 22. The elastic clamping plates 21 are respectively clamped and matched with the arc-shaped grooves provided at the lower end of the inner arc surface of the stepped hole. The upper end of the installation cylinder 22 is internally threaded with an anode rod 9. A limiting ring 24 that cooperates with the elastic clamping plates 21 is vertically slidably connected inside the installation cylinder 22.

Pull the limiting ring 24 upward through the connecting frame 25 to compress the spring 23. Then insert the installation cylinder 22 equipped with the anode rod 9 into the stepped hole in the middle of the top cover 4. The elastic clamping plate 21 at the lower end of the installation cylinder 22 is clamped and matched with the arc-shaped groove provided at the lower end of the inner arc surface of the stepped hole. Then, under the elastic force of the spring 23, the limiting ring 24 moves downward to contact the elastic clamping plate 21, thereby restricting the elastic deformation of the elastic clamping plate 21, and further fixing the installation cylinder 22 and the anode rod 9. After the anode rod 9 is energized, the electrolyte inside the ceramic inner liner 3 reacts. At the same time, the controller 13 controls the motor 11 to work, drives the rotating ring 51 and the blade 52 inside the annular groove 5 to rotate through the gear 12, thereby conveying the gas produced during the reaction upward into the inside of the gas collecting box 6.
