Detailed Description

The invention is described in further detail below with reference to the figures and the embodiments.

As shown in fig. 1 and 2, a multi-functional integrated thick liquid device that advances, including advancing thick liquid pipe 2 that is equipped with box 1 top side, with advance vertical buffer chain 3 that is equipped with in the box 1 that thick liquid pipe 2 is relative, the slant of buffer chain 3 downside is equipped with guide plate 4, the slant of guide plate 4 downside is equipped with and filters sieve 5, the thick liquid discharge gate 6 has been seted up to box 1 bottom that filters 5 downside correspondences, the box bottom side that filters 5 upside lower extremities correspondences has seted up silt particle discharge gate 7.

Preferably, the top of the buffer chain 3 is detachably connected with the bottom of the rotary cover plate 8, one end of the rotary cover plate 8 is hinged to the top of the box body 1, the other end of the rotary cover plate is matched with the top of the maintenance pipe 9, the maintenance pipe 9 is fixed to the top of the box body 1, and the buffer chain 3 is arranged in the maintenance pipe 9 and in a penetrating mode through a through hole formed in the top of the box body 1. After designing like this, conveniently change or maintain buffering chain 3, upwards open rotatory apron 8 earlier this moment, buffering chain 3 is pulled out, then with buffering chain 3 follow 8 bottoms dismantlements of rotatory apron change or maintain can.

Preferably, the baffle 4 is fixed on the inner side wall of the box 1 through a support rod 10.

Preferably, one side of the filtering sieve plate 5 is hinged with the inner side wall of the box body 1, and the other side of the filtering sieve plate is connected with the inner side wall of the box body 1 through a telescopic device 11. Through setting up telescoping device 11, can change the inclination of filtering sieve 5 to the speed that makes the material landing that falls into filtering sieve 5 surfaces and the speed of the lower end ejection of compact of filtering sieve 5 can be adjustable, can adjust according to actual conditions needs can.
