When the wire mesh demister 104 needs to be replaced, the upper wire mesh demister 104 is replaced through the box cover 106, the baffle 103 is driven by the motor 31 to move downward, so that the lower frame 107 and the wire mesh demister 104 enter the liquid storage tank 101, the wire mesh demister 104 is replaced through the maintenance door on the right side of the liquid storage tank 101, so that the filtrate device 10 does not need to stop working, and the function of conveniently replacing the wire mesh demister 104 is realized; On the other hand, the electromagnet 27 is powered off, the elastic rope 29 pulls the sliding block 28 back to the original position, so that the inflation valve 25 is closed and the deflation valve 24 is opened, through the cooperation of the negative pressure state in the box body 1 and the spring rod 17, the gas in the inflatable sealing pad 19 is discharged to the inside of the box body 1, then the controller 3 controls the mold pressing machine body 5 and the door plate 13 to rise synchronously, and then the mechanical arm carries out blanking and feeding, thereby solving the problem that the sealing effect of the single sealing door in the existing waste gas treatment is limited, the waste gas collection rate is low, the waste gas that is not collected will escape to the outside, and the health of the operator is affected.

[0045] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
