Technical Field

[0001] The utility model relates to the technical field of gas purification, in particular to a gas purification adsorption device. Background Art

[0002] In the current gas adsorption purification device, the impurity adsorption process of the adsorbent and the adsorbent analytical purification process have the same adsorption path and analytical path, with adsorption in a high-pressure state and analytical in a low-pressure state. The purpose of activating the adsorbent is achieved by introducing analytical gas and then discharging it.

[0003] During the use of the existing purification adsorption device, when the gas enters the interior, the gas stays in the purification adsorption device for a short time, so it cannot fully contact with the adsorbent, which easily affects the purification of the gas.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-6 A gas purification adsorption device comprises a protective cover 1, a protective cover 2 is hingedly installed on the left side of the protective cover 1, the outer wall of the protective cover 2 abuts against a limiting pin 13, and a movable pin 12 is fixedly connected to the top of the limiting pin 13, a support assembly 11 is sleeved on the surface of the movable pin 12, and the support assembly 11 is fixedly connected to the left outer wall of the protective cover 1, a filter cover 8 is inserted into the inside of the protective cover 1, and the bottom end of the filter cover 8 abuts against a limiting plate 9, a second spring 17 is symmetrically fixedly connected to the front and rear surfaces of the limiting plate 9, and a torsion spring 15 is sleeved on the surface of the second spring 17, one end of the torsion spring 15 is fixedly connected to the limiting plate 9, and the other end of the torsion spring 15 is fixedly connected to the inner wall of the protective cover 1. During use, the end of the torsion spring 15 is fixed to the surface assembly of the protective cover 1 and the limiting plate 9. When the limiting plate 9 rotates around the center of the spring, the spring pulls them back to the initial position to generate torque or rotational force.

[0024] Further, see Figure 5 It can be known that a fixed cover 3 is fixedly installed on the right side of the protective cover 1, and a sealing plug 16 is inserted inside the fixed cover 3. The right surface of the sealing plug 16 is fixedly connected with a protective plate 4. The sealing plug 16 has a conical structure and is made of rubber. The outer wall of the sealing plug 16 is in conflict with the inner wall of the fixed cover 3.

[0025] Further, see Figure 2 It can be known that the protective plate 4 is symmetrically fixedly connected with a fixed block 5 on the upper and lower parts, a movable rod 6 is fixedly connected to the left surface of the fixed block 5, and a limiting component 7 is symmetrically fixedly connected to the right side of the fixed cover 3 on the upper and lower parts. A slot is provided on the surface of the limiting component 7, and the movable rod 6 passes through the slot. The movable rod 6 and the limiting component 7 are slidably connected. During use, the limiting component 7 can limit the movable rod 6.

[0026] Further, see Figure 5It can be known that a limiting ring is provided on the left fixed sleeve of the movable rod 6, and a second spring 17 is provided on the surface of the movable rod 6, and one end of the second spring 17 is fixedly connected to the left outer wall of the limiting assembly 7, and the other end of the second spring 17 is fixedly connected to the right outer wall of the limiting ring. During use, the second spring 17 has a contraction force, which drives the sealing plug 16 to reset, thereby facilitating the sealing effect of the fixed cover 3.

[0027] Further, see Figure 2 and Figure 3 It can be seen that a sealing ring 10 is fixedly connected to the right surface of the protective cover 2, and the right side of the sealing ring 10 is in tight contact with the left outer wall of the protective cover 1. During use, the sealing ring 10 can play a sealing role between the protective cover 2 and the protective cover 1.

[0028] Further, see Figure 3 It can be known that a first spring 14 is sleeved on the surface of the movable pin 12, and the first spring 14 is located between the support assembly 11 and the limit pin 13, the top end of the first spring 14 is fixedly connected to the bottom end of the support assembly 11, and the bottom end of the first spring 14 is fixedly connected to the top end of the limit pin 13. During use, the first spring 14 itself has an elastic force that pushes the limit pin 13 to fit the outer wall of the protective cover 2, thereby facilitating the fixed limit function.

[0029] Working principle: When the utility model is in use, according to the attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 , Attachment Figure 5 and attached Figure 6 As shown, first, air enters the interior of the protective cover 1 through the air inlet opened at the top of the protective cover 1. After the gas enters the interior of the protective cover 1, it is adsorbed by the adsorption material inside the filter cover 8. The gas passes through the filter cover 8 and enters the bottom of the protective cover 1. The gas flows inside the protective cover 1 and fully contacts with the adsorption material until the interior of the protective cover 1 is filled with gas. Then, the sealing plug 16 moves to the left. During the movement of the sealing plug 16, the movable rod 6 is driven to move. The movement of the movable rod 6 drives the limit ring to move. The limit ring squeezes the second spring 17 to a contracted state. At this time, the sealing plug 16 slides out of the interior of the fixed cover 3, and the purified gas is discharged.

[0030] When the filter cover 8 needs to be replaced, the top of the protective cover 1 is manually opened, and a new set of filter covers 8 is inserted inside the top of the protective cover 1. The new filter cover 8 conflicts with the top of the filter cover 8 inside the protective cover 1, and the filter cover 8 moves downward inside the protective cover 1. The filter cover 8 at the end falls to the inner bottom of the protective cover 1. At this time, the movable pin 12 is pulled upward, and the movable pin 12 drives the limit pin 13 to move upward, and the protective cover 2 is hinged open to facilitate the removal of the filter cover 8. During the movement, the limit pin 13 squeezes the first spring 14 to a contracted state. When external force contacts, the limit pin 13 is pushed to reset, and the protective cover 2 is limited. The operation is completed. The above is the entire working principle of the utility model.

[0031] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.

Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
