Description

Technical Field

[0001] The utility model relates to the technical field of molecular sieve bulk density measurement, in particular to a molecular sieve bulk density measuring instrument. Background Technique

[0002] A molecular sieve is a silicon-aluminate compound with a cubic lattice. The molecular sieve has a uniform microporous structure, and the pore diameters of its cavities are uniform. These cavities can adsorb molecules smaller than their diameters into the interior of the cavities, and have a preferential adsorption capacity for polar molecules and unsaturated molecules. Therefore, molecules with different degrees of polarity, different degrees of saturation, different molecular sizes, and different boiling points can be separated, that is, it has the function of "screening" molecules, so it is called a molecular sieve. The bulk density refers to the weight of molecular sieve particles per unit volume, which can be used to evaluate the density and filling performance of the molecular sieve.

[0003] The "device for measuring bulk density" disclosed in the patent application with the application number "202223107544.7" "comprises a funnel 1, at least two groups of support rods 2, a base 3 and at least two groups of telescopic rods 4.

In the present utility model, the telescopic rod is detachably connected to the funnel. According to the experimental requirements, the size of the funnel can be disassembled and replaced.

[0029] During use, first, rotate the screw rod 2302 through the anti-slip grooves 2304 of the support assembly 23 to adjust its height and keep the support plate 1 flat. Then, place the funnel 22 on the support ring 21. The support ring 21 can support the funnel 22 and can horizontally limit it. Then, limit the measuring cylinder 8 by the limiting column 7 to keep the measuring cylinder 8 in a centered state. After that, add the molecular sieve into the funnel 22. The molecular sieve falls into the measuring cylinder 8 through the funnel 22. The retaining frame 2 and the baffle 4 can prevent the molecular sieve from spilling onto the ground. Finally, scrape the molecular sieve flat along the mouth of the measuring cylinder 8, and then weigh it and calculate it through a formula. After the measurement is completed, open the baffle 4 and pour out the molecular sieve through the discharge port 3 to clean the support plate 1;

[0030] The staff member removes the funnel 22 from within the support ring 21, and it can be disassembled, allowing for quick replacement of funnels 22 of different sizes. After the funnel 22 is replaced, the staff member pulls the square rod 1203 through the pull plate 1204 of the first limiting component 12, causing the first convex tooth block 1206 to compress the first spring 1205. Then, the first sliding sleeve 10 is vertically slid to adjust the height of the support ring 21. After that, the pull plate 1204 is released, and the first spring 1205 pushes the first convex tooth block 1206 back to its original position, causing the first convex tooth block 1206 to engage with the first tooth groove 11, thereby locking the first sliding sleeve 10 and preventing the first sliding sleeve 10 from vertically displacing, so that the height of the support ring 21 matches the height of funnels 22 of different sizes. The staff member pulls the square rod 1803 through the pull plate 1804 of the second limiting component 18, causing the second convex tooth block 1806 to compress the second spring 1805. Then, the second sliding sleeve 16 is vertically slid to adjust the horizontal position of the support ring 21, which can center funnels 22 of different sizes and make them coaxial with the limiting column 7. After that, the pull plate 1804 is released, and the second spring 1805 pushes the second convex tooth block 1806 back to its original position, causing the second convex tooth block 1806 to engage with the second tooth groove 15, thus locking the second sliding sleeve 16.
