Description
Technical field
The utility model relates to a kind of sack cleaner access door, is specifically related to a kind of sack cleaner access door with pressure relief device.
Background technology
At present, existing sack cleaner is equipped with the access door of some at the top, be used for maintenance and install and change bag cage, filter bag, sack cleaner is worked under negative pressure state usually, when deduster need overhaul or change a bag cage, filter bag, to open the top access door, because access door bears negative pressure, make that opening the top access door need overcome negative pressure, need just can open with bigger power, also need sometimes just can open by other instruments such as crowbars.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of sack cleaner access door with pressure relief device, and it is convenient and swift to open access door, and good airproof performance.
The technical scheme that the utility model technical solution problem adopts is: a kind of sack cleaner access door with pressure relief device, comprise doorframe and maintenance door closure, described maintenance door closure periphery is provided with flat steel bar and foaming sealing strip, described access door covers and is provided with pressure relief device, described pressure relief device comprises circular pressure release lid, screw rod, screw bolt seat, described screw rod is fixed on the screw bolt seat by Hough formula pressing plate and screw, described screw rod lower end is provided with nut, and described nut is connected with band steel circle integral type with bracing frame; Described circular pressure release lid below is provided with the circular seal sheet.
As a kind of preferred, described circular seal sheet is connected with circular pressure release lid with rivet by clamping plate.
The beneficial effects of the utility model are: when deduster need overhaul, lid sheds negative pressure as long as rotating screw bolt just can easily be opened pressure release, thereby needn't just can open access door like a cork by other instruments such as crowbars, and was easy to operate, good airproof performance.
