The interior of the pressing groove 19 is slidably connected to the pressing block 21. When the staff needs to replace the adsorption plate 13, the pressing block 21 is pressed downward to drive the elastic spring 20 to store force, so that the adjusting plate 13 is replaced. The section rod 16 is released from the limit slot 17, and the adjusting rod 16 is moved out of the limit slot 17 to release the limit of the adsorption plate 13.

Through the setting of the second slide groove 27 and the second slider 28, a limiting path can be formed when the adsorption plate 13 is pulled out and put in, so that the adsorption plate 13 is more stable during the process of pulling out and putting in, thereby improving the replacement efficiency of the adsorption plate 13.

[0033] Reference Figure 2 As shown, in this embodiment: the material of the adsorption plate 13 is activated carbon fiber, which has a strong adsorption capacity for organic gases, inorganic substances in aqueous solutions, dyes, organic substances, and precious metal ions, etc., which can improve the adsorption efficiency of the adsorption plate 13 and improve the purity of the water source after filtration.

[0034] Reference Figure 1 , Figure 6 and Figure 7As shown, in this embodiment: a storage tank support frame 29 is installed on the top of the placement plate 1, and a storage tank body 30 is installed on the top of the storage tank support frame 29. Both sides of the top of the placement plate 1 are provided with traction grooves 31, and a traction block 32 is slidably connected inside the traction groove 31. The top of the traction block 32 is fixedly connected with a connecting column 33, and the end of the connecting column 33 close to the storage tank body 30 is fixedly connected with a circular column 34, and the end of the circular column 34 close to the storage tank body 30 is installed with a clamping plate 35, and the right side of the connecting column 33 is fixedly connected with a connecting plate 36, and the inside of the connecting plate 36 is rotatably connected with a threaded rod 37, and the top of the threaded rod 37 is fixedly connected with a rotating plate 38. A fixing groove 39 is provided at the top of the storage tank body 30, and the number of the fixing grooves 39 is several. When the staff needs to transport carbon dioxide into the storage tank body 30, the rotating plate 38 is rotated upward to drive the threaded rod 37 to rotate out of the fixing groove 39, so that the connection column 33 is released from the limit, thereby releasing the limit of the clamping plate 35, and the clamping plate 35 is moved to a position close to the storage tank body 30, and then the rotating plate 38 is rotated downward to drive the threaded rod 37 to rotate into the fixing groove 39, so that the clamping plate 35 is limited, thereby achieving a stable limit of the storage tank body 30 when carbon dioxide needs to be transported into the storage tank body 30, preventing the storage tank body 30 from being offset during transportation and affecting the transportation efficiency.

[0035] Reference Figure 7 As shown, in the present embodiment: one end of the traction block 32 away from the storage tank body 30 is fixedly connected with a return spring 40, and one end of the return spring 40 away from the traction block 32 is fixedly connected to the inside of the traction groove 31. Through the setting of the return spring 40, when the storage tank body 30 completes the delivery of carbon dioxide, the rotating plate 38 is rotated upward to drive the threaded rod 37 to rotate out, so that the connecting column 33 is released from the limit. At this time, the elastic force stored in the return spring 40 is released, driving the connecting column 33 to rebound quickly, thereby achieving the rapid reset of the clamping plate 35 after the carbon dioxide delivery is completed, which is convenient for the next use.

[0036] Reference Figure 7 As shown, in this embodiment: third sliding grooves 41 are opened on both sides of the traction groove 31, and third sliding blocks 42 are fixedly connected on both sides of the traction block 32. The interior of the third sliding groove 41 is slidably connected to the third sliding block 42. Through the arrangement of the third sliding groove 41 and the third sliding block 42, the traction block 32 can form a guiding effect when moving in the traction groove 31, thereby improving the movement stability of the traction block 32, thereby improving the adjustment efficiency of the clamping plate 35.

[0037] Reference Figure 8 As shown, in this embodiment: a rubber plate 43 is installed at one end of the clamping plate 35 close to the storage tank body 30. Through the setting of the rubber plate 43, when the clamping plate 35 contacts the storage tank body 30, it will have a greater friction force, further improving the stability of the storage tank body 30 after clamping.

[0038] Reference Figure 6 As shown, in this embodiment: the material of the storage tank body 30 is 16MnDR steel plate. The 16MnDR steel plate has greater pressure resistance and thermal insulation properties, which can make the carbon dioxide have better thermal insulation properties during storage, reduce the gasification rate of carbon dioxide, and will not cause deformation of the storage tank body 30 due to the pressure of carbon dioxide, thereby improving the service life of the storage tank body 30.

[0039] Working principle: when the staff needs to replace the adsorption plate 13, the pressing block 21 is pressed downward to drive the elastic spring 20 to store force, so that the adjusting rod 16 is released from the limit groove 17, and the adjusting rod 16 is moved out of the limit groove 17 to release the adsorption plate 13. At this time, the adsorption plate 13 is pulled out for replacement. After the replacement is completed, the adjusting rod 16 is moved to the limit groove 17 to limit the adsorption plate 13, and the pressing block 21 is aligned with the ejection outlet 18. At this time, the elastic force stored in the elastic spring 20 is released, driving the pressing block 21 to quickly pop out into the ejection outlet 18, so that the adjusting rod 16 is released from the limit, thereby achieving rapid replacement when there are too many impurities on the surface of the adsorption plate 13, improving the working efficiency of the device, and through the setting of the first slide groove 22 and the first slider 23, When the adjusting rod 16 moves inside the fixing rod 15, a stable limit is formed, which improves the stability of the adjusting rod 16 when it moves, thereby improving the fixing efficiency of the adsorption plate 13. By setting the stable slide groove 24 and the stable slider 25, when the adjusting rod 16 is in a fixed state, the elastic force of the elastic spring 20 will not cause the adjusting rod 16 to shake, so that the stability of the fixing of the adjusting rod 16 is improved, thereby improving the fixing effect of the adsorption plate 13. By setting the second slide groove 27 and the second slider 28, a limiting path can be formed in the process of pulling out and putting in the adsorption plate 13, so that the adsorption plate 13 is more stable in the process of pulling out and putting in, thereby improving the replacement efficiency of the adsorption plate 13. The activated carbon fiber has good properties for organic gases, inorganic substances, dyes, and organic substances in aqueous solutions. The absorbing plate 13 has a strong adsorption force, and the absorbing efficiency of the absorbing plate 13 is improved, and the purity of the water source after filtration is improved. When the staff needs to transport carbon dioxide into the storage tank body 30, the rotating plate 38 is rotated upward to drive the threaded rod 37 to rotate out of the fixed groove 39, so that the connecting column 33 is released from the limit, thereby releasing the clamping plate 35 from the limit, and the clamping plate 35 is moved to a position close to the storage tank body 30, and then the rotating plate 38 is rotated downward to drive the threaded rod 37 to rotate into the fixed groove 39, so that the clamping plate 35 is limited, so as to achieve the stable limit of the storage tank body 30 when carbon dioxide needs to be transported into the storage tank body 30, so as to prevent the storage tank body 30 from deviating during transportation and affecting the transportation efficiency. By means of the setting of the spring 40, when the storage tank body 30 completes the delivery of carbon dioxide, the rotating plate 38 is rotated upward to drive the threaded rod 37 to rotate out, so that the connection column 33 is released from the limit. At this time, the elastic force stored in the reset spring 40 is released, driving the connection column 33 to rebound quickly, thereby achieving the rapid reset of the clamping plate 35 after the carbon dioxide delivery is completed, which is convenient for the next use. By means of the setting of the third slide groove 41 and the third slider 42, the traction block 32 can form a guiding effect when moving inside the traction groove 31, thereby improving the movement stability of the traction block 32, thereby improving the adjustment efficiency of the clamping plate 35. By means of the setting of the rubber plate 43, when the clamping plate 35 contacts the storage tank body 30, it will have a greater friction force, further improving the stability of the storage tank body 30 after clamping.The 16MnDR steel plate has greater compressive strength and heat preservation, which can make carbon dioxide have better heat preservation when stored, reduce the speed of carbon dioxide gasification, and will not cause deformation of the storage tank body 30 due to the pressure of carbon dioxide, thereby improving the service life of the storage tank body 30.
