fig. 1 is a schematic structural diagram of embodiment 1 of the present invention;

fig. 2 is a schematic structural diagram of embodiment 2 of the present invention;

in the figure: 1, a shell; 2, an air inlet nozzle; 3, a filtering mechanism; 31 a filter shell; 32 a filter element; 321 gas distribution plate; 322 a filtration functional layer; 3221 a filtering net layer; 3222 a cotton filter layer; 3223 an active carbon filter layer; 4 air inlet expansion section; 5 agitating.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

Example 1

Referring to fig. 1, the present invention provides a technical solution: the utility model provides a clean room return air filter equipment, install the inlet nozzle 2 on casing 1 including casing 1 and detachable, detachable installs filtering mechanism 3 in the casing 1, filtering mechanism 3 is including crossing shell 31 and setting up the filter core 32 in crossing shell 31, it includes two gaseous equipartition boards 321 and sets up the filtration functional layer 322 between gaseous equipartition board 321 to cross filter core 32, two gaseous equipartition boards 321 are fixed the setting respectively at 31 tops of filtration shell and bottom, it includes filter screen layer 3221 from top to bottom in proper order to filter functional layer 322, filter cotton layer 3222 and active carbon filter layer 3223.

The distance between the filter screen layer 3221, the filter cotton layer 3222 and the activated carbon filter layer 3223 is gradually increased, so that the resistance to air flow can be gradually reduced, and the normal and smooth air flow is ensured.

The top end inner side of the shell 1 is provided with a magnet ring along the circumference, the outer side of the lower end of the air inlet nozzle 2 is also provided with a magnet ring along the circumference, the air inlet nozzle 2 can be fixedly arranged at the top end of the shell 1 through mutual attraction between the magnet rings, meanwhile, the inner side of the shell 1 is provided with a magnet ring along the circumference, the outer side wall of the filter shell 31 on the filter mechanism 3 is also provided with a magnet ring along the circumference, the filter mechanism 3 can be fixedly arranged in the shell 1 through mutual attraction between the magnet rings, and the filter mechanism 3 can be detached for replacement and maintenance;

the air uniformly distributed plate 321 at the top of the filtering shell 31 can make the air entering the shell 1 uniformly enter the filtering core 32, the air is sequentially filtered and purified through the filtering net layer 3221, the filter cotton layer 3222 and the activated carbon filtering layer 3223 in the filtering function layer 322, so that particle impurities in the circulating air are filtered completely, the air uniformly flows through the air uniformly distributed plate 321 at the bottom of the filtering shell 31, the phenomenon that the rapidly flowing air forms turbulence to increase the flow resistance is avoided, and the energy consumption is reduced.

Example 2

Referring to fig. 2, the air inlet expansion section 4 is detachably installed in the air inlet nozzle 2 to improve the distribution of flowing air, which is beneficial for the flowing air to uniformly enter the casing 1.

The air inlet expanding section 4 is internally provided with an agitator 5 which stirs flowing air and can mix the air, so that the particle impurities in the air are more uniformly distributed, and the subsequent filtering efficiency is ensured.
