Description

Technical Field

[0001] The utility model relates to the technical field of pressure swing adsorption nitrogen making machines, in particular to a fixing component of a pressure swing adsorption nitrogen making machine. Background Art

[0002] Pressure swing adsorption nitrogen generator (PSA nitrogen generator) is a highly efficient gas separation equipment that uses pressure swing adsorption technology to separate high-purity nitrogen from the air.

[0003] In the prior art, a Chinese patent document with the authorization announcement number CN219140376U describes a fixing assembly for a pressure swing adsorption nitrogen generator. The patent uses a fixing mechanism to position and fix the L-shaped plate through a first limiting assembly. The pressure swing adsorption nitrogen generator is lifted by a crane, a wire rope and a lifting lug, and placed on a buffer plate. The restriction of the L-shaped plate by the first limiting assembly is released, and a reset spring drives the slider to move along the inside of the slide groove, so that the inner side surfaces of multiple L-shaped plates fit with the corners of the placement plate, thereby preliminarily limiting the placement plate. The screw is rotated inside the threaded barrel to drive the pressure plate to move downward, squeezing the top corner of the placement plate to fix the placement plate on the buffer plate, thereby fixing the PSA nitrogen generator. When the PSA nitrogen generator needs to be transported, the screw is rotated in the opposite direction to drive the pressure plate to move upward and disengage from the placement plate, and the slider is slid outward to separate the L-shaped plate from the placement plate. The L-shaped plate is positioned and fixed again by the first limit assembly, and the PSA nitrogen generator is lifted by the crane, wire rope and lifting lug.

[0004] According to the records of the cited documents, it is necessary to carry out a cumbersome assembly and disassembly process during installation and disassembly, and it is not convenient to move it alone after disassembly for installing a pressure swing adsorption nitrogen generator.

[0005] To this end, we propose a fixed assembly for a pressure swing adsorption nitrogen generator. Utility Model Content

Reinforcing rods 3 are fixedly installed on the upper parts of the outer surfaces of the two ends of the fixing seat 4, and the reinforcing rods 3 are fixedly installed between the two groups of side panels 2. A clamping groove 7 is opened in the middle of the outer surfaces of the two ends of the rectangular mounting frame 1, and clamping components 10 are installed on the outer surfaces of the two ends of the fixing seat 4. The clamping component 10 includes a mounting groove 11, a guide rod 12, a compression spring 13, a lower inclined wedge 14, an arm plate 15, a connecting plate 16 and a guide ring 17, and a first lifting ring 5 is fixedly installed in the middle of the left and right ends of the outer surface of the upper end of the fixing seat 4, and support legs 8 are fixedly installed on the four corners of the outer surface of the lower end of the fixing seat 4. The lower end outer surface of the support legs 8 is fixedly installed with a locking universal wheel 9, and the front and rear ends of the upper end outer surface of the side panel 2 are fixedly installed with a second lifting ring 6.

[0028] The mounting groove 11 is opened in the middle of the outer surface of both ends of the fixing seat 4, and the guide rod 12 and the compression spring 13 are both located in the mounting groove 11; the outer surface of one end of the guide rod 12 is fixedly connected to the middle of one end of the mounting groove 11, and the compression spring 13 is movably sleeved on the outer wall of the guide rod 12, and the outer surface of one end of the compression spring 13 is fixedly connected to one end of the mounting groove 11, and the outer surface of the other end of the compression spring 13 is fixedly connected to the outer surface of one side of the connecting plate 16; the arm plate 15 is fixedly installed on the left and right sides of the outer surface of one end of the lower inclined wedge block 14, and the connecting plate 1 6 is fixedly installed between the two groups of arm plates 15 at one end away from the lower inclined wedge block 14, the guide ring 17 is fixedly installed in the middle of the connecting plate 16, and the guide rod 12 passes through the guide ring 17; the outer walls of the lower inclined wedge block 14, the arm plate 15, and the connecting plate 16 are all slidably connected to the installation groove 11, and the outer surface of one side of the connecting plate 16 is elastically connected to one end of the installation groove 11 through the compression spring 13; the connecting plate 16 is slidably connected to the outer wall of the guide rod 12 through the guide ring 17, and the outer wall of one end of the lower inclined wedge block 14 is snap-fitted to the snap-fitting groove 7.

[0029] It should be noted that the present invention is a fixing assembly of a pressure swing adsorption nitrogen generator. The pressure swing adsorption nitrogen generator is fixed to the outer surface of the upper end of the fixing seat 4. When the fixing seat 4 is installed, the first lifting ring 5 is lifted by the hoisting machine to lift the fixing seat 4. Then, the fixing seat 4 only needs to be inserted into the interior of the rectangular installation frame 1 to achieve the installation of the fixing seat 4. When the fixing seat 4 is inserted into the rectangular installation frame 1, the lower inclined wedge block 14 in the clamping assembly 10 is squeezed, and the lower inclined wedge block 14 slides along the installation groove 11. The lower inclined wedge block 14 drives the connecting plate 16 to move through the arm plate 15, and the connecting plate 16 squeezes the compression spring 13 along the outer wall of the guide rod 12 through the guide ring 17, so that one end of the lower inclined wedge block 14 enters the installation groove 11. After the lower inclined wedge block 14 reaches one end of the clamping groove 7, the reaction force of the compression spring 13 drives one end of the lower inclined wedge block 14 to be clamped into the clamping groove 7, thereby realizing the installation of the fixing seat 4 and facilitating disassembly. It is only necessary to squeeze the lower inclined wedge block 14 clamped in the clamping groove 7 so that the lower inclined wedge block 14 is separated from the clamping groove 7, and the fixing seat 4 can be lifted out. After the fixing seat 4 is disassembled, it is convenient to move it separately through the provided universal wheel 9 with lock.
