Portable pneumatic cold blast valve for incinerator tail gas treatment system

Abstract

The invention relates to parts of an incinerator tail gas treatment system, in particular to a portable pneumatic cold blast valve for an incinerator tail gas treatment system, which comprises a casing, wherein a shaft supporting seat is welded toone side of the casing, and a spindle is fixed tothe shaft supporting seat; a gland is arranged at the upper part of the casing, the periphery of the lower end of the gland is sleeved with a sealing strip which is in sealed connection with the upper part of the casing, a rib board is manufactured on the upper surface of the gland, a flip rocker arm is connected with the rib board by adopting bolts, a shaft sleeve is welded toone end of the flip rocker arm and meanwhile is installed on the spindle in a penetrating manner. The portable pneumatic cold blast valve is characterized in that an air cylinder supporting seat is welded toone side of the casing, which is adjacent to the spindle; an air cylinder is installed on the air cylinder supporting seat; a connecting rod is connected with an air cylinder piston head, and the other end of the connecting rod is hinged with one end of the spindle; a balance weight leveris installed at the other end of the spindle, and a balance weight blockis installed on the balance weightlever. The portable pneumatic cold blast valve for the incinerator tail gas treatment system is compact in structure, simple and convenient to operate and good in sealing performance, can be automatically switched on / off, and greatly lowers the generation probability of the accidents during the burning of an incinerator.

Description

technical field [0001] The invention relates to components in an incinerator tail gas treatment system, in particular to a portable pneumatic cold air valve used in the incinerator tail gas treatment system. Background technique [0002] The cold air valve is installed on the cold air branch pipe before the cold air enters the incinerator, and it is closed during the combustion period of the incinerator, so that the incinerator is separated from the cold air and closed tightly to ensure the smooth operation of the incinerator. A common cold air valve is a manual gear-type movable grille. This cold air valve has a complex structure and laborious operation. Therefore, it is very important to develop a cold air valve with a simple structure, easy operation, and automatic opening and closing. Contents of the invention [0003] The object of the present invention is to provide a portable pneumatic cold air valve for the incinerator tail gas treatment system which is simple in s...
