Description

Technical Field

[0001] The present application relates to the technical field of specific surface area measurement, and in particular to a fully automatic specific surface area measurement instrument. Background Art

[0002] Specific surface area, also known as specific surface area, refers to the surface area of ​​1g of solid material, which includes the sum of internal surface area and external surface area. It is usually represented by the symbol SA, with the unit of m2 / g. It is one of the most important physical and chemical parameters to characterize the performance of solids. There are many factors that affect the specific surface area, including the pore structure inside the material and the roughness of the surface of the material. The fully automatic specific surface area meter is a measuring device that is widely used in the specific surface area of ​​non-porous powdery materials such as cement, ceramics, abrasives, metals, and gunpowder. The main principle is to measure the specific surface area by the change in flow rate caused by the different resistance encountered when a certain amount of air passes through a cement layer with a certain porosity and fixed thickness.

[0003] After searching, the announcement number: CN218445039U announced a fully automatic specific surface area measuring instrument. By setting a compression spring, a cartridge, and a dovetail block, when the connecting rod is pressed, the compression spring undergoes elastic deformation and will shrink. Since the dovetail block is set on the connecting rod, it is convenient to engage the dovetail block with the dovetail groove, thereby achieving a fastening and preventing the compression spring from stretching and getting out of the engaged state.

[0004] With respect to the above-mentioned related technologies, the inventor believes that there are the following technical defects that need to be improved:

[0005] The existing float is easily stuck at the corner of the U-shaped tube when water is poured, and is difficult to remove; and when this device is used to seal the top of the barometer, a person needs to manually press the connecting rod to complete the engagement of the barometer and the card cover. The force of this process is difficult to control, and there is a risk of damaging the card mouth. Utility Model Content

[0015] In summary, the present application includes at least one of the following beneficial technical effects:

[0016] 1.
