exemplary embodiments

Example 1

As in 1-4 shown, the utility model provides an apparatus for separating and purifying 1,2,4,5-tetramethylbenzene, which comprises a box body 1, both sides of the inner wall of the box body 1 being provided with sliding grooves 2, a sliding member 3 being slidable within the two sliding grooves 2, both sides of the top and bottom of the sliding part 3 are fixedly connected to the first elastic member 4 and the second elastic member 5, respectively, with an end of the first elastic member 4 remote from the sliding part 3 fixed to the first screen 6, wherein an end of the second elastic member 5 remote from the slide 3 is fixedly connected to a second screen 7, the third screen 8 is fixedly connected between both sides of the inner wall of the slide 3, the top and Bottom of the slider 3 are provided with mounting holes 9, the number of mounting holes 9 is several, the front de s box body 1 is hinged to a box door 10, with a first attachment cylinder 11 communicating with the top of the box body 1, with a second attachment cylinder 12 communicating with the top of the first attachment cylinder 11, with the feed nozzle 13 communicating with the top of the outer surface of the second fixing cylinder 12, wherein the first fixing cylinder 11, the second fixing cylinder 12 and the feeding nozzle 13 are arranged so that the 1,2,4,5-tetramethylbenzene can enter the box body 1 more dispersedly so that it can be screened more easily.

According to this embodiment, in operation, start the motor 15 to bring the 1,2,4,5-tetramethylbenzene to be separated and purified into the box body 1 through the first sieve 6 through the feed nozzle 13 , the first fixing cylinder 11 and the second fixing cylinder 12 . The motor 15 drives the cam 18 to rotate and drives the cross plate 16 and slide 3 to move up and down by the action of gravity to feed the 1,2,4,5-tetramethylbenzene over the first screen 6 shake. The 1,2,4,5-tetramethylbenzene is quickly and completely sieved through the first sieve 6. The screened 1,2,4,5-tetramethylbenzene falls into the slide portion 3 through the mounting hole 9 and is screened through the third screen 8 twice.
