The implementation principle of the embodiment is as follows:

the sludge with moisture is introduced into the plate frame 14, then the hydraulic cylinder 11 is started, the piston rod of the hydraulic cylinder 11 pushes the filter pressing plate 12 to enable the filter pressing plate 12 to slide towards the plate frame 14 along the rack 1, then the filter pressing plate 12 is abutted against the plate frame 14 and pushes the plate frame 14 to slide towards the stop plate 13, finally the plate frame 14 is abutted against the stop plate 13, the moisture of the sludge in the plate frame 14 is extruded under the action force of the filter pressing plate 12, and a dry filter cake is left in the plate frame 14.

Controlling the hydraulic cylinder 11 to move reversely, so that the plate frame 14 is separated from the abutting state with the stop plate 13, and the filter cake in the plate frame 14 falls down and falls into the collecting tank 2 for uniform collection; when the filter cake quantity in the collecting vat 2 is too much to need the clearance, start and collect motor 21, it rotates the lead screw 22 that drives and collect motor 21's pivot key-type connection to collect motor 21, lead screw 22 rotates and drives scraper bowl 23 and slide bar 233 and slide in the inside cavity of collecting vat 2 along lead screw 22, and because the both sides of push pedal 231 and swash plate 234 all with the inside wall butt of collecting vat 2, the one end and the collecting vat 2 bottom plate butt that push pedal 231 was kept away from to swash plate 234, therefore when push pedal 231 and swash plate 234 removed to drain 24, can push the filter cake that falls in collecting vat 2 and remove to drain 24. In the process, the inclined plate 234 scoops up the filter cake, reducing the friction between the filter cake and the bottom plate of the collection tank 2. And because second connecting plate 42 takes place relative displacement and has produced the friction with collecting vat 2, consequently second connecting plate 42 can constantly wear out, then expanding spring 45 can promote second connecting plate 42 this moment, makes it slide along first connecting plate 41 to compensate for the second connecting plate 42 that wears out, and keep the second connecting plate 42 and with the butt state between the bottom plate of collecting vat 2.

In the filter cake falls into drain 24 in the promotion of push pedal 231 and swash plate 234, meanwhile, through rotating locking strip 263, make locking strip 263 and locking groove 262 break away from the joint state to rotate shutter 25, make shutter 25 break away from the lid and close drain 24 state, then the filter cake all falls into in transport vechicle 3 through drain 24.

When excessive filter cakes in the transport vehicle 3 need to be transported to the next process, the transport vehicle 3 is pushed, the roller 313 rotates and rubs with the ground to reduce the friction force, when the transport vehicle 3 needs to turn, the force in the required direction is applied, the wheel carrier 312 rotates a certain angle along with the force, and the roller 313 is driven to rotate a certain angle to complete the turning of the transport vehicle 3; when the transport vehicle 3 needs to be braked and stopped, the pedal 33 is stepped to rotate the pedal 33 along the rotating shaft 32 for a certain angle, so that the brake pad 34 is abutted against the roller 313, and the transport vehicle 3 is braked and stopped by the friction force between the roller 313 and the brake pad 34.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
