A rotary valve and a five-tube adsorption tower using it, and an oxygen generator

Abstract

The invention discloses a rotating valve. The rotating valve comprises a half-closed separating chamber of which the bottom part is provided with an opening; an air inlet is formed in one side of the separating chamber; a through hole N is formed in the top part of the separating chamber; a motor is mounted on the top part of the separating chamber; a transmission rod of the motor is inserted into the through hole N and extends into an inner cavity of the separating chamber; the free end of the transmission rod of the motor is connected with a movable blade; a static blade is mounted and clung to the lower end of the movable blade; the movable blade can freely rotate relative to the static blade, wherein the static blade is of a cylindrical structure; a first group of through holes is uniformly formed in the static blade along the circumference; a T-shaped nitrogen discharging groove, an arc-shaped air feeding groove and a homogenizing groove are formed in the movable blade. The invention further provides a five-pipe absorbing tower provided with the rotating valve, and an oxygenator. The rotating valve is adapted to the a multi-absorbing-pipe type absorbing tower structure; the multi-absorbing-pipe integral type absorbing tower is high in oxygen generation efficiency, high in concentration and small in nose; the oxygenator employing the technology is stable and reliable to work, and the user experience is good.

Description

technical field [0001] The invention belongs to the field of household or medical oxygen making equipment, and in particular relates to a rotary valve, a five-tube adsorption tower using the same, and an oxygen making machine. Background technique [0002] Household or medical oxygen generators on the market are based on the principle of PSA pressure swing adsorption, using air as raw material, fluorspar molecular sieve as adsorbent, and using the different diffusion rates of oxygen and nitrogen in the compressed air in the molecular sieve pores to achieve continuous production. purpose of oxygen. [0003] Traditional oxygen generators are generally installed with double adsorption tube adsorption towers controlled by solenoid valves. The oxygen production efficiency is relatively slow, the flow rate and concentration of oxygen production are not high, and the noise is loud during the working process, resulting in poor user experience. . . And when it is installed on the ...

AI Technical Summary

Problems solved by technology

[0003] Traditional oxygen generators are generally installed with double adsorption tube adsorption towers controlled by solenoid valves. The oxygen production efficiency is relatively slow, the flow rate and concentration of oxygen production are not high, and the noise is loud during the working process, resulting in poor user experience.

Moreover, when it is installed on the oxygen generator, it is all installed on the oxygen generator one by one, and its installation steps are loaded down with trivial details

[0004] In addition, there is no rotary valve suitable for the multi-adsorption tube adsorption tower structure in the prior art.
