[0052] In order to enable the lifting frame 40 to automatically descend, as shown, Figure 4 , Figure 9 - Figure 10 , Figure 12 As shown, one side of the moving seat 33 is provided with a driving groove 39, driving shafts 41 are rotatably arranged on the two sides away from each other of the lifting frame 40, the driving shafts 41 are matched with the driving groove 39, the driving shafts 41 can be in contact with the inner wall of the driving groove 39, when it is needed to dewater the mud cake, only the moving seat 33 needs to be controlled to translate, so that the lifting frame 40 can automatically descend, specifically: when the moving seat 33 translates, the driving shafts 41 will enter the driving groove 39, because of the inclined inner wall of the driving groove 39, the moving seat 33 can make the driving shafts 41 and the lifting frame 40 automatically descend when moving, active dewatering can be realized: the double-purpose assembly drives the dewatering assembly to extrude the mud cake, so as to reduce the water content of the mud cake, and in the process of discharging the residue, the lifting frame 40 will also automatically descend, so that the extrusion mesh frame 42 can automatically push out the mud cake in the process of discharging the residue, thereby realizing automatic discharge of the residue.

[0053] In order to prevent the bevel claw 35 from being blocked during the dehydration of the mud cake and the resetting of the moving seat 33, as shown in Figure 7 , Figure 9 , one side of the bevel claw 35 is provided with a collision control assembly, which includes a hollow seat 36 fixed on one side of the moving seat 33, an electric telescopic push rod 37 fixed on the inner side of the hollow seat 36, the electric telescopic push rod 37 being connected to an external power source and a switch through wires, a wedge block 38 fixed on the shaft end of the electric telescopic push rod 37 and slidingly connected to the moving seat 33, the wedge block 38 being in contact with the bevel claw 35, the arc claw 34 being in contact with the pressing guide plate 11 and the supporting sliding arm 19, and the bevel claw 35 being in contact with the pressing guide plate 11 and the supporting sliding arm 19. When it is necessary to rotate and press the bevel claw 35 to prevent it from being blocked, the electric telescopic push rod 37 is only needed to be controlled to extend, so that the lower end of the bevel claw 35 is lifted by the wedge block 38, the upper end of the bevel claw 35 is rotated and pressed, and the bevel claw 35 is prevented from being blocked, so that the moving seat 33 can smoothly translate.

[0054] In order to further improve the sealing performance between the two filter frames 12 during the dehydration of the mud cake, as shown in Figure 16 , a dual-purpose assembly and a dehydration assembly are used to further improve the sealing performance of the sealing assembly. The dehydration assembly can further improve the sealing performance of the sealing assembly when it extrudes the mud cake. Specifically, the dehydration assembly can extrude the auxiliary air bag 2 to inflate the air bag sealing ring 1 to further improve the sealing performance of the sealing assembly. In specific implementation, the auxiliary air bag 2 is fixed on the upper side of the filter frame 12 and the top lower side of the lifting frame 40. A plurality of pull ropes 51 are fixed on the inner side of the auxiliary air bag 2. The pull ropes 51 can prevent the auxiliary air bag 2 from expanding significantly and can ensure that the gas in the main air bag 3 does not enter the auxiliary air bag 2 in large quantities, thereby ensuring the sealing performance of the air bag sealing ring 1. The lower side of the auxiliary air bag 2, the upper side of the filter frame 12, and the upper side of the air bag sealing ring 1 are provided with through holes. The upper communication tube 48 is fixed on the inner side of the through hole. The through hole and the through hole on the filter frame 12 are in communication with the frame groove. When the mud cake is dehydrated, the lifting frame 40 will be lowered, and at this time, the lifting frame 40 will extrude the auxiliary air bag 2 to inflate the air bag sealing ring 1, thereby further increasing the air pressure in the air bag sealing ring 1, thereby further improving the sealing performance between the two air bag sealing rings 1, and preventing the extrusion of the solid impurities and water leakage of the extrusion net rack 42 when the mud cake is extruded.

[0055] The working procedure of the embodiment is that: firstly, the plurality of filter plate assemblies are arranged on the cross beam 6 in sequence, then the oil cylinder 8 is controlled to extend, so that the pressing plate 9 presses the plurality of filter plate assemblies, then the high-pressure sewage is supplied into the water inlet pipe 7 to carry out filtration and separation, during the filtration and separation, self-adaptive sealing can be carried out, when it is needed to dehydrate the mud cake, the mud cake is actively dehydrated through the dual-purpose assembly and the dehydration assembly, after the dehydration is completed, the moving seat 33 is reset, during this period, the moving seat 33 is reset with the aid of the anti-collision control assembly, when it is needed to discharge the residue, the oil cylinder 8 is controlled to retract, then the filter plate assemblies are sequentially pulled open by the dual-purpose assembly to discharge the residue, during the residue discharging process, the mud cake can be automatically pushed out through the cooperation of the dual-purpose assembly and the dehydration assembly, so that the automatic residue discharging is realized.

[0056] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
