The utility model will be further described with reference to fig. 1 and 2.
A tower plate liquid draining device of a flat liquid receiving plate comprises an overflow weir 7 arranged on a tower plate 2 and a lifting device 8 fixedly connected to the side wall of the overflow weir. The overflow weir is positioned at one end of the tower plate connected with the liquid receiving plate 5, ensures the liquid seal of the downcomer 3, enables the liquid to uniformly flow into the lower tower plate, and reduces the impact of the liquid flow in the horizontal direction, thus being arranged at the liquid flow inlet end. The liquid receiving plate is fixed on the tower wall 1, and the lower part of the liquid receiving plate is fixed through a rib plate 6. The side wall of the downcomer 3 is positioned on the tower wall through the positioning sheet 4, so that the stability of the downcomer is increased.
The lifting device comprises a plurality of lifting blocks 17 which are uniformly arranged along the overflow weir. The lifting block vertically penetrates through the tower plate and freely lifts relative to the tower plate. The lifting block drives the overflow weir to lift, so that the liquid retained in the liquid receiving tray flows onto the tower plate.
The top of the lifting block is fixedly connected with a fixed plate 13, the fixed plate is fixedly connected with the side wall of the overflow weir, a liquid inlet hole 15 and a liquid discharge hole 16 vertical to the axial direction of the liquid inlet hole are arranged on the lifting block in parallel along the flowing direction of liquid, the top of the liquid discharge hole is communicated with the liquid inlet hole, and the bottom of the liquid discharge hole is arranged at the bottom of the lifting block. When the lifting device is lifted, part of liquid flows through the lifting block through the liquid inlet hole or flows to the lower tower plate through the liquid outlet hole.
The bottom of the lifting block is fixedly connected with a limiting plate 14, a through hole penetrates through the limiting plate, and the through hole corresponds to the liquid discharge hole. The limiting plate and the fixing plate limit the lifting range of the lifting block together.
Limiting plate lateral part rigid coupling lug 12 runs through on the lug and is provided with the through-hole, and supporting screw 9 runs through the lug through the through-hole, and supporting screw all passes through threaded connection with upper nut 10, lower nut 11, and upper nut and lower nut are located the lug top and below respectively, and the relative position of supporting screw and lug is adjusted and fastened in the cooperation of upper nut and lower nut, and the length of supporting screw is greater than the sum of the height of elevator and limiting plate.
