Description

Technical Field

[0001] This utility model relates to the field of gas treatment technology, and in particular to an emergency switching system for dual adsorption cylinders. Background Technology

[0002] Gas purification refers to the removal of impurities, pollutants, harmful components, or unwanted substances from gases through physical, chemical, or biological methods to improve gas purity and quality. Adsorption cartridges are key equipment used in gas or liquid purification, separation, and refining processes. Their core function is to use the adsorbent filled inside to remove target impurities or specific components from fluids through physical or chemical adsorption, thereby purifying the fluid or recovering valuable substances.

[0003] A search revealed that Chinese patent CN220834818U discloses an adsorption cylinder. To ensure uniform distribution and tight filling of carbon molecular sieves within the cylinder, the usual method involves manually striking the cylinder surface with a hammer to induce vibration, significantly increasing workload and reducing filling efficiency. Therefore, this method first reverses the rotation of the threaded rod, releasing the clamps from their gripping position on both sides of the adsorption cylinder. Simultaneously, a return spring pushes the clamp at one end of the T-shaped movable rod against the surface of the adsorption cylinder. Then, a vibration motor is activated, causing the adsorption cylinder to vibrate. This vibration ensures uniform distribution of the carbon molecular sieves, guaranteeing a tight filling. Furthermore, the clamps, pressed against the cylinder surface by the return spring, provide some protection to both sides, further increasing the cylinder's stability.

[0004] While the aforementioned adsorption cylinders facilitate the filling of molecular sieves, production interruptions and reduced gas treatment efficiency are easily caused when a single adsorption cylinder reaches adsorption saturation or requires maintenance. Furthermore, in existing technologies, molecular sieves and activated carbon are sometimes manufactured in cylindrical shapes to facilitate filling the adsorption cylinders. However, when the cylindrical molecular sieves and activated carbon inside the adsorption cylinder experience long gas purification times and adsorption blockages, they are usually difficult to replace in a timely manner, requiring machine shutdown for replacement. This reduces the continuity of gas treatment and lowers the efficiency of gas purification. Utility Model Content

With the two adsorption cylinders integrated with a pressure sensor, it facilitates an emergency switch to the other adsorption cylinder when one cylinder reaches gas saturation, improving the continuity of gas processing. After switching to the other adsorption cylinder, opening the threaded cap of the saturated adsorption cylinder releases the positioning of the activated carbon filter cylinder and the molecular sieve filter cylinder, making it easier to pull the activated carbon filter cylinder and the molecular sieve filter cylinder out from the outside of the mounting rod. This helps to improve the replacement efficiency of the activated carbon filter cylinder and the molecular sieve filter cylinder and reduce downtime.

Pressure sensors 4 are fixedly installed on the inner walls of both ends of the connecting pipe 2 for monitoring internal pressure. Both ends of the connecting pipe 2 are connected to an upper shell 5, and an air outlet shell 6 is fixedly connected to the lower surface of the upper shell 5. An activated carbon filter cartridge 7 is provided inside the air outlet shell 6, and a molecular sieve filter cartridge 8 is provided on the inner wall of the activated carbon filter cartridge 7. Two mounting grooves 9 are opened inside both the activated carbon filter cartridge 7 and the molecular sieve filter cartridge 8 to facilitate the installation and connection of the mounting rod 10. A replacement component is provided inside the upper shell 5.

[0035] As attached Figure 6As shown, the replacement assembly includes multiple mounting rods 10, which are fixedly connected to the inner wall of the upper shell 5. Multiple cylindrical grooves 11 are provided on both sides of the mounting rods 10 for the retraction of the extrusion block 14. Limiting grooves 12 are provided on both sides of the cylindrical grooves 11 to facilitate the sliding of the limiting blocks 15 and to limit the movement of the extrusion block 14. A fastening spring 13 is fixedly connected inside the cylindrical groove 11, and one end of the fastening spring 13 is fixedly connected to the extrusion block 14. Under the push of the elastic force of the fastening spring 13, the multiple extrusion blocks 14 can be squeezed against the inner wall of the mounting groove 9, so that the activated carbon filter cartridge 7 and the molecular sieve filter cartridge 8 are fixedly installed to the outside of the mounting rods 10 through the mounting groove 9. Limiting blocks 15 are fixedly connected on both sides of the extrusion block 14, and the limiting blocks 15 are slidably connected inside the limiting grooves 12 to prevent the extrusion block 14 from detaching from the cylindrical groove 11.

[0036] As attached Figure 7 As shown, an outer shell 16 is fixedly connected to the outside of the gas outlet shell 6. A gas outlet pipe 17 is connected through one side of the outer shell 16. A pipe cap 18 is threaded to one end of the gas outlet pipe 17 to facilitate the discharge of gas.

[0037] As attached Figure 1 As shown, a support foot 19 is fixedly connected to one side of the outer shell 16 to improve stability, and a threaded cap 20 is threadedly connected to the lower surface of the air outlet shell 6 to facilitate opening the lower opening of the air outlet shell 6.

[0038] As attached Figure 8 As shown, a positioning component is provided on one side of the air outlet shell 6. The positioning component includes a fixing sleeve 21, which is fixedly connected to one side of the air outlet shell 6. A circular plate 22 is slidably connected inside the fixing sleeve 21, which limits the T-shaped rod 23. The T-shaped rod 23 is fixedly connected to the middle of the circular plate 22. A push spring 24 is fixedly connected to one side of the circular plate 22. One end of the push spring 24 is fixedly connected to the inner wall of the fixing sleeve 21, which pushes the T-shaped rod 23.

[0039] As attached Figure 4 As shown, an insertion hole 25 is provided on one side of the activated carbon filter cartridge 7, and the T-shaped rod 23 engages with the insertion hole 25 to facilitate the positioning and fixing of the activated carbon filter cartridge 7.

[0040] As attached Figure 9 As shown, a fixing rod 26 is fixedly connected to the inner wall of the upper shell 5. A threaded hole 27 is opened inside the fixing rod 26, which matches the thread of the stud 28. The stud 28 is threaded inside the threaded hole 27. A knob 29 is fixedly connected to one end of the stud 28 to facilitate the rotation of the stud 28.

[0041] Working principle: When in use, the gas supply pipe to be purified is connected to the inlet pipe 1, and then the switching valve 3 on one side is opened. When the gas enters the molecular sieve filter cartridge 8 through the connecting pipe 2, it is filtered and then passes through the activated carbon filter cartridge 7. After passing through the outlet shell 6, it enters the outside of the outer shell 16. Then the pipe cover 18 is opened and the gas is discharged through the outlet pipe 17. When one of the pressure sensors 4 detects that the pressure value is too high, it will close the switching valve 3 on the side with the higher pressure value and open the other switching valve 3, so that one gas channel is closed and the other gas channel is open, which is convenient for emergency switching.

[0042] After the activated carbon filter cartridge 7 and the molecular sieve filter cartridge 8 are respectively installed on the outside of the fixing rod 26 and secured by multiple pressing blocks 14, when disassembling the activated carbon filter cartridge 7 and the molecular sieve filter cartridge 8, first rotate the threaded cap 20 to remove it from the outside of the gas outlet shell 6, so that the lower opening of the gas outlet shell 6 is open. Then, if it is necessary to replace the molecular sieve filter cartridge 8, turn the knob 29 to drive the stud 28 to rotate inside the threaded hole 27, so as to release the compression on the molecular sieve filter cartridge 8 and release the limit. Then move the molecular sieve filter cartridge 8 down to remove it from the mounting rod 10, thus completing the disassembly of the molecular sieve filter cartridge 8. When disassembling the activated carbon filter cartridge 7, first pull the T-shaped rod 23 to pull one end into the inside of the fixing sleeve 21 and out of the inside of the insertion hole 25, so that the activated carbon filter cartridge 7 is released from the limit. Then move the activated carbon filter cartridge 7 down to remove it from the mounting rod 10, thus completing the disassembly of the activated carbon filter cartridge 7. This facilitates the flexible replacement of the two. The above operations are reversed during installation.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
