Hinge-type valve installing structure in bag-type duster

Abstract

The invention discloses a valve-lift installing structure in the bag-type duster, which has simple structure and is practical and reliable. The hinge-type valve installing structure in the bag-type duster comprises a lift valve and a pore plate, wherein the lift valve and the pore plate are arranged at the upper end of a box body, ventilation holes are arranged on the pore plate, the upper end ofthe box body is divided into an air-purifying chamber and a ventilation channel by the pore plate, the pore plate is obliquely arranged on the box body between the air-purifying chamber and the ventilation channel, a retainer ring is arranged on the pore plate of the outer side of the ventilation holes, and a valve rod of the lift valve is articulated with a valve cover which is mutually matched with the retainer ring by a hinge shaft. The hinge-type valve installing structure in the bag-type duster has simple structure and is practical and reliable, the valve cover and the pore plate are obliquely arranged, air flows can smoothly pass through the pore plate, eddy flows are not easy to generate at the end of the air-purifying chamber in order to reduce pressure loss to the maximum extent and improve ventilation effect. When the lift valve has faults, the valve rod drops to automatically open the valve cover and does not influence the normal operation of a duster and a boiler.

Description

technical field [0001] The invention relates to a bag type dust remover, in particular to an installation structure of a hinged valve in the bag type dust remover. Background technique [0002] The installation structure of the hinged valve in the existing bag filter includes: a poppet valve and an orifice plate arranged on the upper end of the box body, a vent hole is provided on the orifice plate, and a vent hole is provided on the valve stem of the poppet valve. The valve cover and the orifice plate that cooperate with each other divide the upper end of the box into two parts: the clean air chamber and the air passage. The orifice plate is horizontally arranged on the box between the clean air chamber and the air passage. The valve is horizontally arranged on the upper end of the box body and cooperates with the orifice plate. When the installation structure of the lifting valve mentioned above is installed in the bag filter for use, the lifting valve is opened, and the ...

AI Technical Summary

Problems solved by technology

Because the valve cover and the orifice plate are arranged horizontally, the air flow is prone to turbulence at the end of the clean air chamber, resulting in a relatively large pressure loss and affecting the ventilation effect. When the poppet valve fails, the valve stem will fall to close the air flow channel, which will affect the dust removal. Normal operation of appliances and boilers
