[0002] With the development of society, various chemical companies have emerged one after another. During the chemical production process, some harmful dust, harmful gases and other toxic substances are generated. For example, in the various links and manufacturing processes of activated carbon production, if these harmful substances are directly discharged into the air, it will not only pollute the environment, but also cause direct harm to the human body in serious cases. Therefore, air purification equipment is needed in the production process to purify the air before it is discharged into the atmosphere.

[0003] Existing purification mechanisms cannot automatically adjust according to flow rate and blockage. When the flow rate of harmful substances is high, the filter area is fixed, resulting in inadequate filtration and a low pass rate. When the flow rate is low, waste occurs. Furthermore, when the filter is clogged, it cannot be replaced in time, affecting efficiency. Utility Model Content

[0012] Beneficial effects achieved by this utility model:

[0013] The utility model provides a purification mechanism for chemical production. When the upper end of the filter cartridge is higher than the inner cartridge and the part is blocked or the flow increases, the filter cartridge is pushed to move upward, so that the unused part of the filter cartridge located between the purification cartridge and the inner cartridge moves upward, so that the filter cartridge is adapted to the flow rate and the service life is extended, and it does not need to be replaced immediately due to blockage.

A filter cartridge 6 is movably connected to the inner cylinder 5 so that the filter cartridge 6 is located on the inner cylinder 5 and can move up and down, so that the filter cartridge 6 can be adjusted according to the flow rate or blockage. The height is automatically adjusted according to the situation. When the lower end of the filter cartridge 6 abuts against the upper surface of the first annular seat 4, the upper end of the filter cartridge 6 is higher than the inner cylinder 5 by a predetermined height. The portion where the upper end of the filter cartridge 6 is higher than the inner cylinder 5 has the lowest pass rate of harmful substances. When the upper end of the filter cartridge 6 is higher than the inner cylinder 5 and the portion is blocked or the flow rate increases, the filter cartridge 6 is pushed to move upward, so that the unused portion of the filter cartridge 6 between the purification cylinder 1 and the inner cylinder 5 moves upward, so that the filter cartridge 6 is adapted to the flow rate and the service life is extended, and it will not be replaced immediately due to blockage.

[0023] In this embodiment, in order to achieve the limiting effect, the outer wall of the lower end of the filter cartridge 6 is connected to a limiting ring 7, and the inner wall of the upper end of the purification cartridge 1 is provided with a second annular seat 8. The filter cartridge 6 is respectively slidably and sealedly matched with the second annular seat 8 and the inner cartridge 5.

[0024] In this embodiment, a limiting spring 9 is connected between the limiting ring 7 and the second annular seat 8. The limiting spring 9 can place the purification mechanism in any direction, for example, it can be tilted or placed horizontally, and is not limited to the vertical direction, so that the filter cartridge 6 will not slide automatically in any direction.

[0025] In this embodiment, in order to avoid backflow, a float 10 is provided in the cavity formed by the filter cartridge 6 and the lower end of the purification cartridge 1. The size of the float 10 is larger than the diameter of the air inlet pipe 2, and the lower end surface of the purification cartridge 1 has an outwardly convex arc section.

[0026] Wherein, the filter cartridge 6 is an activated carbon plate or filter screen with a cylindrical structure.

[0027] In this embodiment, in order to facilitate disassembly and assembly, the purification cylinder 1 includes a first connecting cylinder 101 and a second connecting cylinder 102, the first annular seat 4 is located on the inner wall of the first connecting cylinder 101, and the second annular seat 8 is located on the inner wall of the second connecting cylinder 102, and the first connecting cylinder 101 and the second connecting cylinder 102 are movably connected, including a bolt connection or a threaded connection.

When the filter cartridge 6 moves upward, the push rod 16 is pushed upward for a predetermined distance, and the conductive sheet 14, the conductive ring 17, the power supply and the solenoid valve 18 form a circuit. When the filter cartridge 6 is clogged, the fluid continues to push the filter cartridge 6 upward, and the upward movement of the filter cartridge 6 pushes the push rod 16 upward, so that the conductive sheet 14 is connected to the conductive sheet 14. Since the solenoid valve 18 is a normally closed type, when the conductive sheet 14 is connected to the conductive ring 17, the conductive sheet 14, the conductive ring 17, the power supply and the solenoid valve 18 form a loop, so that the solenoid valve 18 located on the next purification mechanism is opened, which not only makes the filter cartridge automatically adjust its height according to the flow rate or blockage situation to adapt to the flow rate, but also makes full use of the filter cartridge while avoiding unnecessary waste, further extending the use time and improving the filtering effect.
