By using above-mentioned technical proposal, at the middle part for needing to open erecting bed, the piston rod for squeezing cylinder stretches out, and makes It obtains sealing plate to separate with erecting bed, since the internal diameter that the diameter of sealing plate is greater than erecting bed is less than the internal diameter of tower body, pass through at this time The exhaust gas of filtering can be flowed downward to by the gap and sealing plate of sealing plate and erecting bed and the gap of tower body inner wall from In center device；At the middle part for needing to seal erecting bed, the logical piston rod for squeezing cylinder is moved up so that sealing plate is supported with erecting bed It connects, so that sealing is blocked by sealing plate in the middle part of erecting bed, so that sewage is not easy to flow into centrifugal device when cleaning strainer.

The utility model is further arranged to: the sealing plate is fixedly arranged above Gask-O-Seal, and gasket uses rubber Glue is made.

By using above-mentioned technical proposal, when sealing in the middle part of erecting bed, sealing plate is contacted by gasket with sealing station, Since gasket is made using rubber with certain elasticity, to improve sealing effect.

The utility model is further arranged to: extension table is fixed in the middle part of the sealing plate, when gasket and erecting bed When abutting, the upper end of extension table is aligned with the lower end of drainage hole.

By using above-mentioned technical proposal, when gasket is abutted with erecting bed, under the upper end and drainage hole of extension table End alignment is so that the water being located in extension table can be discharged by drainage hole, so that being not easy ponding on sealing plate.

The utility model is further arranged to: the upper end of the extension table is fixed with diversion platform, and the diversion platform is circular cone Shape.

By using above-mentioned technical proposal, sewage can be oriented to erecting bed by diversion platform, so that sewage is easier to from drainage hole Discharge improves drainage efficiency.

The utility model is further arranged to: the cylinder that squeezes is externally provided with the protective shell fixed with tower body, the protection Shell is made of corrosion resistant material.

By using above-mentioned technical proposal, when processing has corrosive gas, protective shell can rise to cylinder is squeezed To protective effect, it is not easy to be corroded so that squeezing cylinder.

The utility model is further arranged to: the tower body includes pedestal and extending seat, and the lower end of the extending seat is fixed There is connected unit, connected unit is protruded into pedestal and connect with whorl of base.

By using above-mentioned technical proposal, when needing replacing strainer, more extending seat is separated with pedestal, then by strainer Dismounting is replaced, so that screen replacing is more convenient.

In conclusion the utility model has the following beneficial effects:

When carrying out exhaust-gas treatment, sealing plate is moved down by squeezing cylinder, enables and divides exhaust gas to lead to through filter screen filtration The gap in the gap and sealing plate and tower body inner wall of crossing sealing plate and erecting bed flows downward in centrifugal device, is needing clearly When filter wash net, sealing plate is moved up as erecting bed abutting by squeezing cylinder, then spraying water by spray tube, it is clear to carry out to strainer Reason, the sewage after cleaning directly will not can pollute centrifugal device by drainage hole discharge, can pass through sealing after cleaning Plug blocks drainage hole, so that exhaust gas is not easy to reveal when exhaust-gas treatment, without opening centrifugal treating tower when cleaning strainer, thus real Filter gauze cleaning convenient function while to exhaust gas filtering is showed.
