The biomass filter material multistage squeezing-grinding type municipal sludge dewatering machine according to claim 7, characterized in that: the sewage recovery subassembly includes water guide cover (8), bracing piece (9), cistern (10) and outlet pipe (17), outlet pipe (17) are equipped with two sets ofly, a set ofly extrude the bottom intercommunication in storehouse (12) with mud, and another group of outlet pipe (17) and side filter screen (23) and the strip type groove intercommunication that mud extruded storehouse (12) inner wall constitutes, interior bottom department of support frame board (1) installs cistern (10), cistern (10) and outlet pipe (17) intercommunication, bracing piece (9) are installed at the top of cistern (10), water guide cover (8) are installed at the top of bracing piece (9), shock dynamo (18) are installed to top one side of conveying section of thick bamboo (19).

9. The biomass filter material multistage squeezing-grinding type municipal sludge dewatering machine according to claim 8, characterized in that: the municipal sludge dewatering machine also comprises the following using method:

step 1: guiding sludge to be dewatered into the feeding cylinder (2), and starting a driving motor (5);

step 2: the end screw rod (31), the connecting rod (30), the first bevel gear (27) and the spiral conveying rod (25) can be driven to rotate through the rotation of the driving motor (5);

and step 3: the first bevel gear (27) drives the second bevel gear (29) to rotate, the second bevel gear (29) drives the connecting rotating shaft (28) to rotate, the connecting rotating shaft (28) drives the linkage rotating rod (3) to rotate, the linkage rotating rod (3) drives the stirring blades (4) to rotate, and the stirring blades (4) stir sludge to prevent blockage;

and 4, step 4: when the sludge enters the conveying cylinder (19), the sludge is transmitted and conveyed through the spiral conveying rod (25), and sewage attached to the surface of the sludge falls on the primary screening net (7) through the bottom screening net (22) under the gravity in the conveying process and falls in the reservoir (10) through the primary screening net (7) and the water guide cover (8);

and 4, step 4: some sludge passing through the bottom filter screen (22) rolls on the inclined primary filter screen (7) and falls into the sludge extrusion bin (12);

and 5: when the driving motor (5) is driven, the connecting rotating rod (21) is synchronously driven to rotate, so that the connecting rotating rod (21) drives the reservoir (10) to rotate, and the reservoir (10) drives the hinged connecting rod (11) to move;

step 6: the upper hinged extrusion plate (34) is driven by the hinged connecting rod (11) to shake up and down to extrude the sludge on the inclined net (15);

and 7: the extruded sludge enters a water outlet pipe (17) through an inclined net (15) and a side filter screen (23), and then enters a reservoir (10) through the water outlet pipe (17);

and 8: when the hinged connecting rod (11) moves, the L-shaped side connecting rod (24) can be driven to move up and down in the side filter screen (23), and then the upper fixing plate (35) and the limiting block (32) are adjusted to move up and down to clean the side filter screen (23) and prevent blockage.
