Abstract

The invention relates to a self-operated molecular sieve compacting device, which comprises an adsorption cylinder body containing molecular sieves, the top of the adsorption cylinder body has a hole and a sleeve body protruding from the surface of the adsorption cylinder body is arranged coaxially, and the sleeve body is One end is open and the other end is closed. The open end is connected to the adsorption cylinder. A cylinder rod that can move freely in the axial direction runs through the end surface of the closed end of the cover body coaxially. The end surface of the closed end of the cover body is connected to the Sealing packing is filled between the cylinder rods, one end of the cylinder rod extends to the inside of the casing and is coaxially connected with a cylinder piston plate with a through hole, and a compression spring is coaxially sleeved outside the cylinder rod, and the two ends of the compression spring Respectively withstand the upper surface of the piston plate of the cylinder and the lower surface of the closed end of the cover body; the lower surface of the piston plate of the cylinder is arranged coaxially and closely in turn with a circular stainless steel wire mesh and a circular palm pad. It does not need to rely on external gas and electric energy, and has the characteristics of simple structure, convenient and reliable use, and high efficiency and energy saving.

Description

technical field [0001] The invention relates to a molecular sieve compacting device, in particular to a self-powered molecular sieve compacting device, which is suitable for the compacting device of molecular sieves in adsorption cylinders in PSA oxygen generators and nitrogen generators. technical background [0002] Since pressure swing adsorption nitrogen production and oxygen generator oxygen-nitrogen separation adsorption cylinders need to be filled with molecular sieves, with the periodic cycle of adsorption and desorption, the gas pressure in the adsorption cylinders also changes periodically, and the molecular sieves interact with each other under this pressure. The gap between them is easy to change, which promotes friction between them and produces inevitable pulverization, thereby reducing the overall stack volume. If this phenomenon is not dealt with, the consequences of gas production will be reduced and the purity of gas produced will be reduced. In view of th...
