vat

2, 2 one side through connection of collecting vat has fluid-

discharge tube

16, 2 top openings in collecting vat are equipped with guiding

gutter

3, and 3 bottoms of guiding gutter run through and are equipped with

weeping hole

4, 2 fixed surface in collecting vat are equipped with briquetting 5 down, 5 both sides fixed mounting of briquetting has dog 6 down, 6 one side fixed mounting of dog has
