Molecular sieve pneumatic quantitative filling device and method

Abstract

The invention provides a molecular sieve pneumatic quantitative filling method and device. Including: silo, discharge pipe, hopper, hopper cover, pneumatic joint and spiral plate. The device uses pneumatic filling to greatly improve the molecular sieve filling efficiency, reduce the time-consuming molecular sieve filling, and reduce manual filling. Waste and pollution caused by repeated dredging and filling during operation. It reduces the exposure time of molecular sieves in the air and absorbs too much moisture in the air, reduces the loss of adsorption capacity and activity capacity of molecular sieves, and has a simple structure and convenient operation, which solves the problem of long manual filling time and low efficiency of molecular sieves. It is easy to block the filling holes of low-temperature gas cylinders and the molecular sieves are exposed to the air for a long time to absorb too much moisture in the air, resulting in the problem of reduced adsorption capacity and activity of molecular sieves, reducing production operation time, improving processing efficiency and product quality, suitable for It is used for filling molecular sieves in cryogenic containers, especially small containers such as cryogenic bottles.

Description

technical field [0001] The invention belongs to the field of cryogenic container manufacture and provides a molecular sieve pneumatic quantitative filling device. Background technique [0002] The cryogenic container is made of inner and outer containers. The interlayer adopts a high-vacuum multi-layer winding structure. The interlayer is placed on the side of the inner container to absorb the interlayer gas to prolong the vacuum life. Molecular sieves have low density, low accumulation rate, and strong spherical rolling properties. Manual quantitative filling needs to go through processes such as weighing, filling, dredging, feeding, and sealing. This method takes a long time to manually fill the molecular sieve, and the efficiency is low. The molecular sieve sphere is easy to block the inlet of the filling hole of the low-temperature gas cylinder. It is necessary to manually clear the blockage with filaments. Repeat the above filling and dredging many times until the molec...

AI Technical Summary

Problems solved by technology

This method takes a long time to manually fill the molecular sieve, and the efficiency is low. The molecular sieve sphere is easy to block the inlet of the filling hole of the cryogenic gas cylinder. It is necessary to manually clear the blockage with a filament. Repeat the above filling and dredging until the molecular sieve of the required quality is filled.

Because molecular sieves are exposed to the air for a long time to absorb too much moisture in the air, the adsorption capacity and activity of molecular sieves are reduced.
