Embodiment 1

As shown in Figure 1-4, the utility model proposes a device for separating and purifying pyrene, including a box 1; chute 2 is provided on both sides of the inner wall of box 1, and the inside of the two chute 2 A sliding member 3 is slidingly connected. A first elastic member 4 and a second elastic member 5 are fixedly connected to both sides of the top and bottom of the sliding member 3 respectively, and the end of the first elastic member 4 away from the sliding member 3 is fixedly connected to a first screen. Net 6, one end of the second elastic member 5 away from the sliding member 3 is fixedly connected with a second screen 7, a third screen 8 is fixedly connected between both sides of the inner wall of the sliding member 3, and the top and bottom of the sliding member 3 are evenly connected. There are several fixing holes 9 . The front of the box 1 is hinged with a door 10 through a hinge. The top of the box 1 is connected with a first fixing tube 11 , and the top of the first fixing tube 11 is connected There is a second fixed cylinder 12 in communication, and the top of the outer surface of the second fixed cylinder 12 is connected with a feed nozzle 13. Through the arrangement of the first fixed cylinder 11, the second fixed cylinder 12 and the feed nozzle 13, the pyrolene can be more dispersed. into the box 1, making it easier to screen.

In this embodiment, when in use, the motor 15 is started, and the tetramethylbenzene that needs to be separated and purified is put into the top of the first screen 6 inside the box 1 through the feed nozzle 13, the first fixed cylinder 11 and the second fixed cylinder 12. , the motor 15 drives the cam 18 to rotate, and drives the horizontal plate 16 and the sliding member 3 to reciprocate up and down through the action of gravity, thereby shaking the pyrene above the first screen 6, and passing the first sieve 6 to the pylene.
