Description

Technical Field

[0001] This utility model relates to the field of multi-stage reverse high-efficiency nitrogen generators, and particularly to a multi-stage reverse high-efficiency nitrogen generator. Background Technology

[0002] The multi-stage reverse high-efficiency nitrogen generator is a nitrogen generation device based on the principle of pressure swing adsorption. By utilizing the difference in the adsorption capacity of a specific adsorbent for oxygen and nitrogen under different pressures, it achieves efficient separation of nitrogen and oxygen, thereby producing high-purity nitrogen.

[0003] Existing multi-stage reverse high-efficiency nitrogen generators typically include a base plate, multi-stage filters, a tank, and a control box. The base plate is located at the bottom of the tank and the control box, and it supports the tank and the control box. The multi-stage filters can perform multi-stage reverse filtration operations, and the control box can control the tank and the multi-stage filters.

[0004] The bottom of the control box is usually fixed with a welded support rod, which is fixed to the top of the base plate. The support rod can support the control box. When maintaining the control box, it is usually maintained in its original position. However, this method has the disadvantage that the control box cannot be flipped over during maintenance, and the staff needs to stand in different positions to operate, which increases the labor intensity. Multi-stage reverse high-efficiency nitrogen generators are not convenient for removing the control box for maintenance, which has certain limitations. Utility Model Content
