Description

Technical Field

[0001] The utility model relates to the technical field of carbon black processing, in particular to an adjustable carbon black oil value testing device. Background Art

[0002] Carbon black, also known as carbon black, is a type of amorphous carbon. It is a light, loose, and extremely fine black powder with a very large surface area, ranging from 10 to 3000m2 / g. It is a product obtained by incomplete combustion or thermal decomposition of carbon-containing materials (coal, natural gas, heavy oil, fuel oil, etc.) under insufficient air conditions. The oil value of carbon black needs to be tested during the processing process.

[0003] The utility model application number CN202122092806.6 discloses an adjustable carbon black oil value test device. The left and right supporting plates can be adjusted vertically through a supporting structure, and their left and right relative positions can be adjusted by connecting a cross plate. Both the left and right supporting plates are provided with hollow cavities, each with negative pressure air holes connected to the hollow cavities. One side of each left and right supporting plate is connected to a negative pressure air source through a pipe, allowing the glass plate to be stably placed on the glass plate placement space.

[0004] The above device fixes the glass plate on the glass plate placement space through negative pressure, but requires manual adjustment of the positions of the left and right supporting plates, which is inconvenient to adjust. The glass plate cannot be placed directly under the microburette. When dripping carbon black oil, the carbon black oil cannot be dripped on the center of the glass plate. The carbon black oil easily drips from the glass plate, which reduces the test effect and reduces the test quality.

[0005] It should be noted that the above content falls within the technical knowledge of the inventor and does not necessarily constitute prior art. Utility Model Content

[0012] Furthermore, the exhaust pipe is a retractable flexible hose.

[0013] Furthermore, leveling feet are connected to the four corners of the bottom of the test platform, and anti-slip pads are installed on the bottom of the leveling feet.

[0014] Compared with the existing technology, this technical solution has the following beneficial effects:

[0015] The cross-shaped slot makes it easy to place and take the glass plate. The glass plate is adsorbed on the lifting plate by negative pressure to prevent the glass plate from shifting and improve the fixing effect. The lifting plate and glass plate are driven by the telescopic cylinder to move up and down, making it easy to adjust the height of the glass plate.
