as shown in fig. 1 to 2, the first, second and third gravity dewatering modules 1, 2, 3 are arranged in two ways, respectively as follows:
the second gravity dewatering component 2 and the first gravity dewatering component 1 are arranged above the third gravity dewatering component 3 in a staggered mode from bottom to top in sequence. Namely the first gravity dewatering assembly 1
And secondly, the first gravity dewatering component 1 and the second gravity dewatering component 2 are arranged above the third gravity dewatering component 3 in parallel. The first gravity dewatering component 1 is positioned at the upper part of the left part of the third gravity dewatering component 3, and the second gravity dewatering component 2 is positioned above the middle part of the third gravity dewatering component 3.
The first and second gravity dewatering modules 1 and 1 are identical in construction. The first gravity dewatering component 1 comprises a first filter belt 11, a first feed inlet 12, a first roller shaft 13, a second roller shaft 14 and a first motor. The first gravity dewatering component 1 has the structure that: include first roller 13, with first roller 13 parallel arrangement's second roller 14, first filter belt 11 cup joints at first roller 13 and second roller 14, forms the annular. A first feeding hole 12 is formed in the upper face of the first roller shaft 13, and one end of the first roller shaft 13 is connected with an output shaft of a first motor. The sludge enters the first filter belt 11 from the first feed opening 12, and the first filter belt 11 moves from right to left, that is, the first filter belt 11 transports the sludge from the first roll shaft 13 to the second roll shaft 14, and the sludge falls from the second roll shaft 14 to the third filter belt 31 of the third gravity dewatering assembly 3.
The second gravity dewatering component 2 comprises a second filter belt 21, a second feed inlet 22, a third roller shaft 23, a fourth roller shaft 24 and a second motor. The structure of the second gravity dewatering component 2 is as follows: the second filter belt 21 is sleeved on the third roll shaft 23 and the fourth roll shaft 24 to form a ring shape. And a second feeding hole 22 is formed in the third roller shaft 23, and one end of the third roller shaft 23 is connected with an output shaft of a second motor. The sludge enters the second filter belt 21 from the second feed opening 22, and the second filter belt 21 moves from right to left, i.e. the second filter belt 21 transports the sludge from the third roller 23 to the fourth roller 24, and the sludge falls from the fourth roller 24 onto the third filter belt 31 of the third gravity dewatering assembly 3.
The third gravity dewatering component 3 comprises a main dewatering roll 33, a fifth dewatering roll arranged in parallel with the main dewatering roll 33, a third filter belt 31 and a fourth filter belt 32 which are sequentially sleeved with the main dewatering roll 33, and a sixth dewatering roll arranged on the upper right of the third filter belt 31, wherein the third filter belt 31 moves from left to right.

The third belt 31 and the fourth belt 32 form a wedge angle in the wedge-shaped zone at the side of the main dewatering roll 33. The wedge angle is 4-6 degrees. The wedge-shaped area is longer than the wedge-shaped area in the prior art, and the sludge still contains moisture when entering the wedge-shaped area and is in a semi-dry state, and if the wedge-shaped area is shorter, the sludge is rapidly extruded up and down by the two filter belts, so that the sludge is easy to run. The utility model discloses a wedge is longer, and the length of wedge does 1/2 of main dewatering roll 33 and the 34 intervals of fifth roller, speed is slower when semidry mud receives the extrusion of two filter belts, and mud is less at the pressure that receives at the same time, is difficult for appearing running the phenomenon of mud to also can extrude partial moisture content in slow extrusion, ensure when getting into "S" type squeeze dewatering area 4, mud can discharge about 70% moisture content, improved the efficiency and the effect of pressure filter dehydration.

If the sludge amount and the water content of the two feeding holes are the same, the movement speeds of the first filter belt 11 and the second filter belt 21 are the same; if the sludge amount and the water content of the two feeding ports are different, the moving speeds of the first filter belt 11 and the second filter belt 21 can be respectively adjusted according to the sludge amount and the water content: if the sludge quantity and the water content of the first feeding hole 12 are larger, the moving speed of the first filter belt 11 is slower than that of the second filter belt 21; if the sludge amount and the water content of the second feed port 22 are large, the moving speed of the first filter belt 11 is faster than that of the second filter belt 21. After the sludge is subjected to gravity dehydration from the first filter belt 11 and the second filter belt 21, the sludge falls into the third filter belt 31 for further gravity dehydration, and at the moment, the water content of the sludge subjected to the two times of gravity dehydration is basically removed by 70 percent to form a semi-solid state. The semi-solid sludge moves to the wedge-shaped area, the sludge is slowly extruded by the fourth filter belt 32 and is slowly dehydrated under pressure, and the sludge running phenomenon cannot happen to the semi-solid sludge. The sludge passes through the wedge-shaped zone and is tightly clamped by the third filter belt 31 and the fourth filter belt 32 at the wedge-shaped angle, and the sludge is wound around the main dewatering roll 33 to enter the S-shaped press dewatering zone 4 for press dewatering.
