Description

Technical Field

[0001] The utility model relates to the technical field of nitrogen generators, in particular to a clamping anti-separation type nitrogen generator. Background Art

[0002] A nitrogen generator is a device used to extract nitrogen from the air to the required purity level. It usually separates nitrogen and oxygen in the air by physical or chemical methods to produce high-purity nitrogen. This type of nitrogen generator uses the different adsorption capacities of adsorbents for nitrogen and oxygen. In a pressure shaker, the adsorption and desorption processes are controlled by changing the pressure. In the adsorption stage, nitrogen is adsorbed onto the adsorbent, while oxygen is removed.

[0003] In the nitrogen generator, the main storage location for the adsorbent is the adsorption tank. When in use, the installation and fixation of the adsorption tank not only need to maintain good stability, but also because the adsorbent needs to be replaced after long-term use to ensure a good adsorption effect, so the convenience of its disassembly is also an important consideration. Therefore, it is necessary to design a clamping stabilization structure to ensure the stable installation of the adsorption tank. Utility Model Content

DETAILED DESCRIPTION

[0018] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] Example

[0020] like Figure 1-5As shown, the utility model proposes a clamping anti-detachment type nitrogen generator, including a chassis 1, a fixed clamp 3 and a movable clamp 4, a mounting groove 11 is opened in the chassis 1, a pair of adsorption tanks 2 are arranged in the mounting groove 11, and are symmetrically distributed, the fixed clamp 3 is fixed in the mounting groove 11 and is located on the side away from the adsorption tank 2, the movable clamp 4 is slidably connected to the middle position of the mounting groove 11 and is symmetrically distributed, a center plate 5 is fixed in the mounting groove 11 and is located between the movable clamps 4, a positioning plate 53 is rotatably connected in the center plate 5, and both ends of the positioning plate 53 are against the movable clamp 4, a limiting block 42 is fixed to the inner side wall of the movable clamp 4, and a limiting groove 41 adapted to the limiting block 42 is opened on the inner side wall of the mounting groove 11.

[0021] A through hole 51 is provided in the middle of the center plate 5, and a center shaft 52 is rotatably connected in the through hole 51. A positioning plate 53 is fixed on the center shaft 52, and both ends extend out of the through hole 51. The positioning plate 53 is an elliptical structure, and the short diameter length of the positioning plate 53 is less than the width of the center plate 5. The upper end of the center shaft 52 extends out of the through hole 51, and an end plate 54 is installed. Positioning rods 55 are fixed at the four corners of the bottom of the end plate 54. The positioning rods 55 are equidistantly distributed on the periphery of the center shaft 52. The bottom of the positioning plate 53 is inserted into the through hole 51 and abuts against the outer wall of the positioning plate 53. A square groove 56 is provided at the upper end of the center shaft 52, and a square rod 57 is slidably connected in the square groove 56. The upper end of the square rod 57 extends out of the square groove 56 and is fixed to the bottom of the end plate 54. A telescopic spring 58 is fixed between the bottom of the square rod 57 and the inner wall of the square groove 56.

[0022] In this embodiment, the adsorption tank 2 is first placed between the fixed clamp 3 and the movable clamp 4, and the movable clamp 4 is slid toward the side of the fixed clamp 3 to clamp the adsorption tank 2. Then, the positioning plate 53 is rotated to make the two ends of the positioning plate 53 abut against the outer side of the movable clamp 4 to fix the movable clamp 4, thereby fixing the adsorption tank 2. The operation is simple and convenient. When disassembling, the adsorption tank 2 can be easily taken out by rotating the positioning plate 53. When rotating the positioning plate 53, the end plate 54 needs to be pulled first so that the bottom of the positioning rod 55 is moved from the hole. When the end plate 54 is pulled out from the hole 51, the rotation limit of the positioning plate 53 is released under the condition of stretching the telescopic spring 58. On the contrary, after the positioning plate 53 is rotated to the specified position, the telescopic spring 58 is reset to pull the end plate 54 to reset, so that the positioning rod 55 can be reinserted into the through hole 51, so that the end plate 54 cannot rotate, thereby ensuring that the positioning plate 53 cannot rotate, and finally achieving the purpose of stable clamping. When the adsorbent particles in the adsorption tank 2 are replaced or filled, the adsorption tank 2 can be quickly disassembled and assembled, and there is no need to lock or disassemble the adsorption tank 2 one by one, thereby improving work efficiency.
