Description

Technical Field

[0001] The present invention relates to the technical field of oxygen-enriched units, and in particular to an energy-saving and environmentally friendly oxygen-enriched unit and a use method thereof. Background Art

[0002] By using air separation technology and the adsorption performance of molecular sieves, the nitrogen and oxygen in the air are separated through physical principles, ultimately obtaining high concentrations of oxygen and nitrogen.

[0003] When nitrogen and oxygen are separated by molecular sieves, air enters from the top of the molecular sieve. Dust and water vapor in the air are adsorbed in the top space of the molecular sieve, affecting the separation of nitrogen and oxygen in the air by the molecular sieve. In addition, the adsorption at the top of the molecular sieve is used frequently, while the bottom of the molecular sieve is less contaminated. When the molecular sieve particles are replaced regularly, they generally need to be replaced manually as a whole. At the same time, when the molecular sieve particles are replaced, there is a risk of insufficient filling areas inside the barrel, which in turn affects subsequent normal use.

[0015] A method for using an oxygen-enriched unit for energy conservation and environmental protection, the specific operating steps of the method are as follows:

[0016] Step 1: The air compressor pressurizes the air and injects it into the gas storage tank. The air in the gas storage tank passes through the filter and freeze dryer and enters the barrel. It enters from the air inlet pipe on the top of the barrel. When passing through the molecular sieve particles, the nitrogen is adsorbed by the molecular sieve particles. The oxygen is collected into the oxygen storage tank through the oxygen exhaust pipe. When the molecular sieve particles in the barrel are saturated with nitrogen, the vacuum pump works to generate negative pressure in the barrel. The adsorbed nitrogen is collected into the nitrogen storage tank through the nitrogen exhaust pipe. The two barrels are used alternately.

[0017] Step 2: Add the molecular sieve particles into the first conical shell through the feeding pipe. At this time, the first motor drives the sprocket to rotate, and the barrel sleeve is driven to rotate through the chain transmission until the connecting groove of the barrel sleeve coincides with the feeding groove and the discharging groove. The second motor drives the rotating shaft and the spiral blade to rotate, and the molecular sieve particles in the barrel are driven to move upward. The molecular sieve particles in the first conical shell are supplemented into the barrel, and the molecular sieve particles located above the barrel enter the second conical shell, so as to realize the automatic replacement of the molecular sieve particles in the barrel. After the replacement is completed, the barrel sleeve is rotated until the connecting groove is staggered with the feeding groove and the discharging groove;

[0018] Step 3: The shaft rotates, and the swivel seat is driven to rotate through the reducer. During the rotation of the swivel seat, the roller rolls along the outer wall of the swivel seat under the action of the spring, thereby driving the movable rod to move back and forth. The rubber block at the end of the movable rod impacts and vibrates the barrel during material change to ensure that the molecular sieve particles in the barrel sleeve are tightly filled.

[0019] The beneficial effects of the present invention are as follows: the position of the connecting groove is adjusted by rotating the barrel sleeve, and then the two ends of the barrel are automatically opened and closed in cooperation with the feeding groove and the discharging groove. When the two ends of the barrel are in an open state, the second motor drives the rotating shaft and the spiral blade to rotate, driving the molecular sieve particles in the barrel to move upward, and the molecular sieve particles in the first conical shell are supplemented into the barrel, and the molecular sieve particles located above the barrel enter the second conical shell, and the molecular sieve particles in the barrel are gradually replaced from top to bottom, thereby realizing the automatic replacement of the molecular sieve particles in the barrel.

[0020] During the replacement process, the shaft rotates, and the swivel seat is driven to rotate through the reducer. During the rotation of the swivel seat, the roller rolls along the outer wall of the swivel seat under the action of the spring, thereby driving the movable rod to move back and forth. The rubber block at the end of the movable rod impacts and vibrates the barrel when changing materials, ensuring that the molecular sieve particles in the barrel sleeve are tightly filled.
