The sludge in transportation above is preliminarily dehydrated through the mutual collision between the gravity of the sludge itself and the high conveyor belt 402, thereby accelerating the dehydration speed and improving the dehydration efficiency.

[0039] Working principle: First, pour the large pieces of sludge into the wedge-shaped crushing chamber between the movable jaw plate 302 and the static jaw plate 301, drive the rotating motor 303 to drive the eccentric wheel 306 to rotate, and then drive the movable jaw plate 302 to move up and down, and the wedge-shaped crushing chamber formed by the cooperation between the movable jaw plate 302 and the static jaw plate 301 to crush the large pieces of sludge. At the same time, through the multiple pressing plates 308 arranged on the inclined surface of the movable jaw plate 302, when the movable jaw plate 302 moves upward, the pressing plate 308 is subjected to the downward pressure of the sludge, so that the pressing plate 308 is pressed downward and turned over, thereby driving the sludge to move upward, and the sludge lifted upward is squeezed and crushed to the static jaw plate 301 by the action of the inclined surface of the movable jaw plate 302. When the movable jaw plate 302 moves downward, the pressing plate 308 and the sludge are squeezed against each other, and the sludge presses the pressing plate 308 performs an upward push to flip the pressure plate 308 upward and open it, and then the opened pressure plate 308 moves downward to press the sludge downward, pushing the sludge to flow downward, and at the same time, multiple top columns 309 at the lower end of the movable jaw plate 302 move up and down to clear the sludge at the outlet of the wedge-shaped crushing chamber up and down, and at the same time, when the top column 309 moves upward, it drives the multiple movable plates 311 to move upward and squeeze the sludge, prompting the multiple movable plates 311 to shrink toward the center of the top column 309, and when the top column 309 falls, it drives the multiple movable plates 311 to move downward and squeeze the sludge, prompting the multiple movable plates 311 to open, press the sludge downward, and push the sludge to flow downward, reducing the phenomenon of sludge accumulation and blockage at the outlet, thereby improving the downward fluidity of the sludge and accelerating the sludge discharge speed.

Then the rotary motor 403 is driven to drive the eccentric disk 404 to rotate, drive the fixed block 406 to move up and down, and drive the high conveyor belt 402 to move up and down to form a certain vibration. The sludge in the upper transport is initially dehydrated through the mutual collision between the gravity of the sludge itself and the high conveyor belt 402, and then The sludge on the high conveyor belt 402 falls onto the low conveyor belt 409 in front, and the low conveyor belt 409 transports the sludge again, dehydrates it again, and then falls between the upper filter cloth and the lower filter cloth below.
