Description

Technical Field

[0001] The utility model relates to the technical field of molecular sieve oxygen generators, in particular to a compression device for a medical molecular sieve oxygen adsorption tower. Background Art

[0002] The entire system of the molecular sieve oxygen generator is fully automatically controlled by a single-chip microcomputer. It generally adopts the pressurized adsorption and normal pressure desorption method. The two adsorption towers carry out the same cycle process respectively, thereby realizing continuous gas supply.

[0003] The existing adsorption tower molecular sieve particles pass through a vacuum feeder and enter the machine's feeding end. The molecular sieve directly falls into a weighing hopper for weighing. When the set weight is reached, the molecular sieve enters the adsorption tower through the discharge port. During discharge, the molecular sieve particles in the adsorption tower are compressed by vibration. However, the traditional method can easily lead to air stagnation when compacting the molecular sieve particles. Therefore, we propose a compacting device for a medical molecular sieve oxygen adsorption tower. Utility Model Content

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The compression device of the medical molecular sieve oxygen adsorption tower is adapted to the outer wall diameter of the steel ball and the inner wall diameter of the circular groove, so that when the pressure plate 1 is raised to the top of the shell, the steel ball and the circular groove are clamped together, which can effectively prevent the pressure plate 1 from being separated from the shell during use. The outer wall of the clamping part is clamped with the outer wall of the pressure plate 1. When the lifting assembly is lifted up and down, the lifting assembly can drive the clamping parts of the pressure plate 1 to lift and lower, so that when the clamping parts are damaged, they can be replaced.
