A monitoring device for environmental protection

Abstract

The utility model provides a kind of monitoring equipment for environmental protection, it is related to environmental protection technical field, including monitoring cylinder, the inside of monitoring cylinder is provided with rotary switching mechanism, rotary switching mechanism includes annular support plate, the inner wall of annular support plate is rotatably connected with air cylinder by sealing bearing, the outside of air cylinder is fixedly sleeved with outer gear ring, by the cooperation of rotary switching mechanism and air intake and exhaust mechanism, make its air cylinder can rotate one hundred and eighty degrees around the sealing bearing of annular support plate, realize the alternate back flushing of two filter screens and air intake, avoid the blockage caused by single filter screen continuous work, and the reciprocating motion of piston is uninterrupted, ensure that humidity monitoring has no pause, satisfy long-term continuous monitoring demand, and by the cooperation of round head sealing tube and support spring, round head sealing tube is closely attached to through hole when back flushing, ensure that the air pressure generated by piston exhaust concentrates on filter screen, effectively strip attached dust, impurity, improve the effect of cleaning efficiency.
