[0037] The working principle and usage process of this utility model are as follows: During use, the metal heat treatment waste gas enters the metal heat treatment waste gas recovery equipment 1 through the air inlet assembly 2 for recovery and treatment. The treated waste gas is discharged through the air outlet pipe 3. When it is necessary to close the air outlet pipe 3, the motor 42 is started. The motor 42 drives the worm gear 43 to rotate, which in turn drives the worm wheel 44 meshing with it to rotate. Simultaneously, the rotation of the worm wheel 44 drives the first gear 45 fixed on its front side to rotate. The first gear 45 drives the second gear 46 meshing with it to rotate. When the second gear 46 rotates, it drives the connecting block 47 fixed on its back side to rotate. The connecting block 47 drives the sealing cover 48 fixed on its left side to rotate, so that the bottom of the sealing cover 48 extends into the interior of the exhaust pipe 3, thereby sealing the exhaust pipe 3. When the sealing cover 48 rotates to the closed position, the first magnet 62 and the second magnet 63 attract each other and the limiting block 61 assists in limiting the movement range of the sealing cover 48. The reverse operation can release the seal on the exhaust pipe 3. The exhaust pipe 3 can be filtered by the filter plate 52 to prevent the flue gas from being directly discharged and affecting the surrounding environment. When maintenance is required, the sealing plate 51 and the filter plate 52 can be removed for maintenance work.

[0038] In summary, this new type of metal heat treatment waste gas recovery box, by adding the functionality of sealing and filtering the exhaust pipe, has the effect of sealing the exhaust pipe to prevent dust and leakage, preventing external dust from entering the exhaust pipe and preventing the exhaust gas generated by the heat treatment waste gas recovery equipment from being discharged, thus solving the problem of external dust entering the exhaust pipe and exhaust gas generated by the heat treatment waste gas recovery equipment being discharged.
