Described V-arrangement pressing plate is fixedly connected with framed bent assembly by securing member, and described V-arrangement pressing plate is provided with elongate holes, and described securing member is through elongate holes.
Described rear seal plate welding has more than at least one the channel-section steel that all rear shroudings are together in series.
The prefilter framed bent of the V-arrangement arrangement of a kind of antidetonation of the present invention has following beneficial effect:
1) described board-like prefilter is arranged on V-shaped arrangement on framed bent assembly, makes to use in the ventilation shaft that sectional area is little, and compared with the board-like prefilter be arranged side by side, the air quantity passed through is large, and resistance is little.
2) the on-the-spot mounting means adopting the pre-buried guide rail of body of wall open circumferential to coordinate special bolt, the surrounding that framed bent assembly surrounding is pressed in framed bent equably by multiple special fixture makes itself and body of wall fix, during maintenance, the nut that only need unclamp special fixture just can realize the dismounting of framed bent.
3) V-arrangement pressing plate is fixedly connected with framed bent assembly by securing member, board-like prefilter is fixed on framed bent assembly by V-arrangement pressing plate, the contact surface place of board-like prefilter and framed bent assembly is provided with sealing gasket, perforate on V-arrangement pressing plate is elongate holes, position fixing on framed bent assembly can adjust front and back, make the sealing gasket uniform force between board-like prefilter and framed bent assembly, avoid airflow bypass thus the filter efficiency of reduction equipment.The securing member that only need unclamp V-arrangement pressing plate just easily can realize the replacing of prefilter fast.
4) rubber seal is arranged on the installation place of framework and body of wall and forms a complete seal face, rubber seal uniform force is made by the thrust of adjustment row special fixture, thus ensure the sealing of metope and framed bent assembly, realize effectively filtering air.
