[0031] It should be noted that the sieve holes 9 densely arranged on the first shower plate 7 and the second shower plate 8 can uniformly distribute the thick slurry to the lower end, and the thick slurry first passes through the first shower plate 7 and is sieved for the first time through the sieve holes 9 on the first shower plate 7. The thick slurry that has not been sieved and the thick slurry that has been sieved once will flow from the outside of the first shower plate 7 and the inside of the sieve holes 9 into the second shower plate 8, and then be sieved for the second time through the second shower plate 8. The thick slurry flowing into the shell 1 is uniformly distributed to the lower end after being sieved twice.
