Above-mentioned technical scheme, set up the annular seal pad on the annular side wall of overhauing the flange, and the sealed U type structure joint of annular seal pad is on the annular side wall, so at the in-process of normal switch, the sealed pad of annular seal can not drop, and the sealed upper side wall that fills up of annular is located the upper surface of annular side wall, realize sealed with access door lid cooperation in-process, in order to promote the effect, the width of the sealed upper side wall that fills up of annular is great, in order to promote sealed effect, and its lower width of lateral wall is less relatively, can save the cost. When opening simultaneously, only need unscrew adjusting nut for the screw rod can follow the draw-in groove and rotate and break away from to its injecing can, the xarm can rotate round the round pin axle between connecting block and the engaging lug, realizes opening of access door cover, otherwise then can realize closing of access door cover. The operation is simple and convenient, the opening is fast and efficient, and the reliability is high.
The access door cover comprises a circular cover plate and an annular baffle plate, the annular baffle plate is arranged on the edge of the lower surface of the circular cover plate, and the inner diameter of the annular baffle plate is larger than the outer diameter of the annular sealing gasket. The design of this structure, the realization that can be better is when closing to the maintenance door closure with overhaul the location between the flange to ensure the stability of assembly and sealed reliability.
The center of the access door cover is provided with a connecting shaft, the connecting shaft and the access door cover are perpendicular to each other, the connecting shaft is rotatably connected with the cross arm through a pin shaft, and the axial direction of the pin shaft between the connecting shaft and the cross arm is consistent with the axial direction of the pin shaft between the connecting lug and the connecting block. The design of this structure is connected through the rotation between connecting axle and the xarm, when can realizing closing the access door lid, can have the swing of certain angle between access door lid and the maintenance flange, and the assembly is more smooth and easy, and in addition, the connecting axle sets up the center at the access door lid for the atress of access door lid is put at central point, thereby ensures that the atress between access door lid and the maintenance flange is more even, has better sealed effect.
A triangular connecting piece is fixed on the connecting block, one side edge of the triangular connecting piece is fixedly connected with the connecting block, and one vertex angle part of the triangular connecting piece, which is opposite to the connecting block, is fixedly connected with the cross arm. The design of this structure can make the connection between connecting block and the xarm more firm, and the length of being connected between connecting block and the engaging lug can increase to at the more stable of rocking arm rotation in-process.
The utility model provides a quick-open access door of forming machine exhaust treatment device, it can realize that access door lid and maintenance realize between the flange rotating to be connected, connects through a screw rod, makes it open and close more simple and convenient, connect the high efficiency soon, through special seal structure design moreover, enables its sealing performance better, and the annular is sealed to be difficult for droing.
