Molecular sieve cylinder for oxygen generator

Abstract

The invention discloses a molecular sieve cylinder for an oxygen generator. The molecular sieve cylinder comprises a cylinder body and a cylinder cover arranged on the right side of the cylinder body,wherein the cylinder body is in threaded connection with the cylinder cover, an air inlet is formed in the left side of the cylinder body, and an air outlet is formed in the right side of the cylinder cover; a molecular sieve is arranged in the cylinder body, a first sieving plate, first filter cotton and a first stainless steel pushing ring are sequentially arranged on the left side of the molecular sieve, a second sieving plate, second filter cotton, a second stainless steel pushing ring and a spring are sequentially arranged on the right side of the molecular sieve, and a first magnetic ring and a second magnetic ring which are respectively matched with the first stainless steel pushing ring and the second stainless steel pushing ring are arranged at the first stainless steel pushing ring and the second stainless steel pushing ring; and a feeding hole and a discharging hole are formed in the side wall of the middle of the cylinder body. The molecular sieve cylinder is novel in design and simple in structure, and the molecular sieve in the molecular sieve cylinder can be very conveniently replaced.

Description

technical field [0001] The invention relates to the technical field of oxygen generators, in particular to a molecular sieve cylinder for an oxygen generator. Background technique [0002] Oxygen concentrator is a kind of machine for producing oxygen. It adopts the adsorption performance of molecular sieve, and through physical principles, it uses a large displacement oil-free compressor as power to separate nitrogen and oxygen in the air and filter out nitrogen in the air. impurities, and end up with high concentrations of oxygen. [0003] The molecular sieve cylinder containing the molecular sieve is a key part of the oxygen generator. However, the existing molecular sieve cylinder is not convenient to replace the internal molecular sieve. It is necessary to take out the molecular sieve cylinder separately, remove the cylinder cover, and then pour out the molecular sieve for replacement. After the replacement, you need to It is time-consuming and labor-intensive to reinst...

[0003] The molecular sieve cylinder containing the molecular sieve is a key part of the oxygen generator. However, the existing molecular sieve cylinder is not convenient to replace the internal molecular sieve. It is necessary to take out the molecular sieve cylinder separately, remove the cylinder cover, and then pour out the molecular sieve for replacement. After the replacement, you need to It is time-consuming and laborious to reinstall the cylinder cover, install the air inlet joint and the air outlet joint, and then put them back in place to fix them.
