[specific embodiment]
Below in conjunction with accompanying drawing technical solutions of the utility model are elaborated.
As shown in Fig. 2 to Fig. 4:
The utility model embodiment provides a kind of pressure curved sieve, includes screen box 1, compass screen surface 2 and tensioning apparatus 3, and described compass screen surface 2 and tensioning apparatus 3 all are located in the screen box 1.Wherein, described tensioning apparatus 3 mainly is comprised of left pressing plate 31, right pressing plate 32 and two nutted rods 33, every nutted rod 33 two ends are equipped with the opposite screw thread of rotation direction (not showing among the figure), left pressing plate 31 and right pressing plate 32 are arc pressuring plate, be respectively equipped with the identical screwed hole of suitable rotation direction (311,322) on it, every nutted rod 33 two ends are screwed into respectively in the corresponding screwed hole (311,322) of two pressing plates (31,32), and two pressing plates (31,32) are pressed on respectively on the compass screen surface 2 of side, screen box 1 both sides.
