The rear of the connecting pipe 4 is installed with a first connecting pipe 6 through a first gas switch valve 5, and the front of the connecting pipe 4 is installed with a second connecting pipe 8 through a second gas switch valve 7.
[0025] According to the above technical solution, the air in the workshop can be conveyed to the air guide cover 2 by the fan 1 and then conveyed to the connecting pipe 4 through 33. At this time, it is conveyed to the positions of the first gas switch valve 5, the first connecting pipe 6, the second gas switch valve 7 and the second connecting pipe 8 from both sides of the connecting pipe 4. At this time, the first gas switch valve 5 and the second gas switch valve 7 can close and open the openings of the connecting pipe 4, so as to realize continuous ventilation and purification treatment.
[0026] Referring to Figures 1 - 3As shown in the figure, the rear end of the first connecting pipe 6 and the front end of the second connecting pipe 8 are both communicated with an outer pipe body 10 through a support pipe 9. A locking ring 12 is threadedly connected above the interior of the outer pipe body 10. The connection between the outer pipe body 10 and the locking ring 12 is provided with a first threaded structure that matches each other. The inner side wall of the locking ring 12 and the upper side of the outer side of the fan 1 are both provided with a second threaded structure that matches each other. The top of the locking ring 12 is fixed with a sealing cover 11 that fits with the top of the outer pipe body 10. The outer diameters of the outer pipe body 10 and the sealing cover 11 are the same, and a sealing ring is provided at the joint where the sealing cover 11 fits with the outer pipe body 10. A ventilation pipe 13 is threadedly connected inside the locking ring 12. The bottom of the ventilation pipe 13 is docked with the through part of the support pipe 9 and the outer pipe body 10. A filter screen 14 and an activated carbon mesh 15 are detachably installed inside the ventilation pipe 13.

Two operating rods 17 for rotating the air outlet pipe 16 are fixed on both sides of the outer wall of the air outlet pipe 16.
[0027] According to the above technical solution, the cavity inside the factory building enters the ventilation pipe 13 inside the outer pipe body 10 through the support pipe 9. At this time, the filter screen 14 and the activated carbon mesh 15 provided inside the ventilation pipe 13 can purify the air. And by operating the operating rods 17, the air outlet pipe 16, the sealing cover 11 and the locking ring 12 can be rotated, and then the ventilation pipe 13 can be detached from the locking ring 12, which is convenient for replacing and maintaining the filter screen 14 and the activated carbon mesh 15.
[0028] Reference Figures 1 - 3 As shown in the figure, a protective net 18 for protecting the air outlet pipe 16 is provided inside the air outlet pipe 16. A protective cover 20 is installed on the top of the air outlet pipe 16 through a support rod 19.
[0029] According to the above technical solution, the outlet of the air outlet pipe 16 can be protected by the protective net 18 and the protective cover 20.
[0030] Advantages of this application: It is convenient to better continuously ventilate and purify the interior of the factory building, and it does not affect the replacement and maintenance of the filter screen 14 and the activated carbon mesh 15.
[0031] Working principle: The air in the factory building can be transported to the diversion hood 2 by the fan 1 and then transported to the connecting pipe 4 through 33. At this time, it is transported to the positions of the first gas switch valve 5, the first connecting pipe 6, the second gas switch valve 7 and the second connecting pipe 8 through both sides of the connecting pipe 4. At this time, the first gas switch valve 5 and the second gas switch valve 7 can close and open the opening of the connecting pipe 4, and continuous ventilation and purification treatment can be realized.
[0032] The cavity inside the workshop enters the ventilation pipe 13 inside the outer pipe body 10 through the support pipe 9. At this time, the filter screen 14 and the activated carbon net 15 arranged inside the ventilation pipe 13 can purify the air. And by operating the lever 17, the air outlet pipe 16, the sealing cover 11 and the locking ring 12 can be rotated, so that the ventilation pipe 13 can be disassembled from the locking ring 12, which is convenient for replacing and maintaining the filter screen 14 and the activated carbon net 15.
