A clamping cover 32 is also fitted onto one end of the mounting shell 3, and a positioning ring 53 is fixedly connected to one end of the separating bucket 5. The positioning ring 53 matches the positioning groove 31, and the clamping cover 32 is used to press the positioning ring 53 into the positioning groove 31. When the operator pulls the clamping cover 32 out from one end of the mounting shell 3 to release the clamping of the positioning ring 53, the separating bucket 5 can be taken out from the mounting shell 3.

[0025] Furthermore, the surface of the separation hopper 5 is densely covered with perforations 51, and magnets 52 are fixedly installed on the inner wall of the separation hopper 5. Multiple magnets 52 are provided. Large particles of impurities in the air cannot pass through the perforations 51 and can be intercepted inside the separation hopper 5. Metal dust in the air can be attracted and collected by the magnets 52.

[0026] Furthermore, the inner wall of one end of the guide pipe 4 is provided with an internal thread, and the surface of the threaded sleeve 33 is provided with an external thread. The external thread and the internal thread cooperate with each other to fix the mounting shell 3 and the guide pipe 4. The inner wall of the other end of the guide pipe 4 is fixedly installed with a support frame 42, and the ultraviolet lamp 43 is installed on the support frame 42. The other end of the guide pipe 4 is fixedly installed with a second flange 41. The exhaust hopper 2 is fixedly installed with a first flange 21 at the end away from the exhaust fan 1. The first flange 21 and the second flange 41 are fixedly connected by bolts.

[0027] Furthermore, a cross rod 61 is fixedly installed inside the annular frame 6, and an activated carbon filter 62 is fixedly installed in the area between the cross rod 61 and the annular frame 6. A pull handle 64 is fixedly connected to the center of the cross rod 61, and an annular frame 44 is fixedly installed on the inner wall of the guide tube 4.

The operator can push the lever 75 by hand to pull the docking rods 72 out of the docking grooves 63, thereby removing the annular frame 6 from the annular frame 44.

[0029] The working principle of this utility model is as follows: Under the action of the exhaust fan 1, the air in the factory workshop passes through the mounting shell 3, the guide pipe 4 and the exhaust duct 2 in sequence and is output to the external environment.

[0030] When air passes through the mounting housing 3, it first enters the separation hopper 5. Large particles of impurities in the air cannot pass through the perforation hole 51 and are intercepted inside the separation hopper 5. Metal dust in the air is attracted and collected by the magnet 52. The air then passes through the perforation hole 51 and enters the mounting housing 3. After that, the air enters the guide pipe 4 and passes through the activated carbon filter 62. The activated carbon filter 62 adsorbs and removes small particles of impurities in the air. Finally, before entering the exhaust hopper 2, the air passes through the ultraviolet lamp 43, which kills the toxic components in the air.

[0031] When it is necessary to clean the separation bucket 5, the staff will pull the clamping cover 32 out from one end of the mounting shell 3 to release the clamping of the positioning ring 53, and then the separation bucket 5 can be taken out from the mounting shell 3 for cleaning.

[0032] When the activated carbon filter screen 62 needs to be cleaned, the worker unscrews the threaded sleeve 33 on the mounting shell 3 from the guide tube 4, pushes the lever 75 upward by hand to make the receiving plate 71 move upward along the guide rod 73, the compression spring 74 contracts under the pressure of the receiving plate 71, the elastic force increases, the receiving plate 71 moves and drives the docking rod 72 to disengage from the docking groove 63. At this time, the worker can pull the annular frame 6 out of the annular frame 44 through the pull handle 64 to clean the activated carbon filter screen 62.

[0033] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense, and may refer to mechanical or electrical connections, internal communication between two components, or direct connection.
