Pneumatic quantitative filling device and method for molecular sieve

Abstract

The invention provides pneumatic quantitative filling device and method for a molecular sieve. The device comprises a material bin, a discharging pipe, a hopper, a hopper sealing cover, a pneumatic connector and a spiral plate. According to the device, through the pneumatic filling, the filling efficiency of the molecular sieve is greatly improved, the time consumption for filling of the molecularsieve is reduced, and waste and pollution caused by repeated clearing and filling in the manual filling operation process are reduced; the exposure and retention time of the molecular sieve in the air and the excessive moisture absorption in the air are reduced, and the adsorption capacity and activity capacity loss of the molecular sieve is reduced; the structure is simple, the operation is convenient, the problems that the molecular sieve is long in manual filling time and low in efficiency, molecular sieve spheres are prone to blocking low-temperature gas bottle filling holes and the adsorption capacity and the activity of the molecular sieve are reduced due to the fact that the molecular sieve absorbs the excessive moisture in the air due to the long-time exposure in air are solved, the production and operation time is reduced, and the processing efficiency and the product quality are improved; and the device is suitable for filling and use of small-sized container molecular sieves such as low-temperature containers and particularly low-temperature 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.
