[0070] Principles and advantages of environmentally friendly river sludge solidification and dewatering equipment:

[0071] First, place the beam frame 1 on the ground. At this time, the guide plate 4 is tilted to one side of the beam frame 1 under the action of the counterweight block 42. Then, the conveyor belt for conveying the mud cake is placed on the tilted side of the guide plate 4, so that the guide plate 4 guides the mud cake discharged from the upper filter press assembly 2 to the conveyor belt for transportation; it is worth mentioning that when the sludge is dehydrated, the pressure block 27 and the pressure plate 26 are pushed by the pressure push rod 23 to squeeze the movable plate frame 22, so that a sludge storage space is formed between the two adjacent movable plate frames 22, and then the filtration is performed. The structure of the fixed plate frame 21 and the movable plate frame 22 and the filtration principle are all prior art and will not be repeated here; after dehydration, the pressure block 27 and the pressure plate 26 are driven to move in the opposite direction by the pressure push rod 23, so that the pressure plate 26 drives the two adjacent movable plate frames 22 to open in sequence through the connecting piece 25, and And the two adjacent movable plate frames 22 maintain a certain distance under the action of the connecting piece 25, so that the mud cake on the filter cloth will automatically fall off; specifically, when the movable plate frame 22 drives the ear plate 24 to slide along the bottom of the beam frame 1, the ear plate 24 drives the ball A242 at the bottom of the bending part 241 to move along the top of the support plate 13, and repeatedly lifts the ball A242 through the groove 14 located at the top of the support plate 13, so that the movable plate frame 22 has a vibration effect during the opening process, so that the mud cake on the filter cloth can be quickly and fully discharged; when several movable plate frames 22 are fully unfolded, the pressure push rod 23 drives the pressure block 27 to continue to move, so that the pressure block 27 drives the pressing component 5 on the outside of the beam frame 1 to trigger the pressing action on the guide plate 4, so that the guide plate 4 automatically adjusts the tilt direction after the mud cake is discharged, so as to collect the cleaning liquid when the filter cloth is cleaned later.

[0072] Its advantages are that the mud cake discharged from the filter press assembly 2 is guided to the conveyor belt on one side of the beam frame 1 by the guide plate 4 to realize the transportation of the mud cake, and after the mud cake is discharged, the guide plate 4 is rotated to change the inclination direction so that the guide plate 4 can guide the subsequent cleaning liquid to a separate container, so as to collect and process the cleaning liquid, which is more environmentally friendly to use; and in order to improve the convenience of use, when the pressure push rod 23 drives the movable plate frame 22 to be fully expanded, the downward pressing action of the downward pressing assembly 5 on the guide plate 4 can be automatically triggered, so as to automatically adjust the inclination direction of the filter press assembly 2 after the mud cake is discharged; and in order to ensure that the mud cake is fully discharged, during the moving and expanding process of the movable plate frame 22, the ball A242 at the bottom of the ear plate 24 cooperates with the groove 14 at the top of the support plate 13 to realize the automatic vibration effect of the movable plate frame 22, so that the mud cake outside the filter cloth can be discharged more conveniently.

[0073] When the cleaning assembly 3 in the environmentally friendly river channel silt solidification and dewatering equipment of the present application is cleaning the filter cloth, the movable plate frames 22 are all in the expanded state, and the spacing is limited by the connecting piece 25 to achieve equidistant arrangement. The gear 322 can be driven by the mobile motor 321 to rotate, driving the slide 32 to slide along the guide rail 15, thereby driving the hanging plate 38 at the bottom of the horizontal plate 37 to be located between the two adjacent movable plate frames 22, and then the brush plate 31 on the outside of the hanging plate 38 is driven by the hydraulic push rod 35 to move between the two movable plate frames 22. At this time, the lower water pipe 311 located below the brush plate 31 first sprays the water on both sides through the outer side nozzles 313 The filter cloth is rinsed, and then the brush plate 31 rotates under the drive of the dual-axis motor 39 to clean the filter cloth. During the cleaning process, the upper water pipe 310 sprays cleaning liquid to the brush plate 31 through the downward nozzle 312 to prevent sludge from adhering to the outside of the brush plate 31 and affecting the cleaning effect. When the brush plate 31 is reset upward, the filter cloth can be finally rinsed through the lateral nozzle 313 to ensure the cleaning effect of the filter cloth; after cleaning, the pressure push rod 23 drives the pressure block 27 to reset. At this time, the guide plate 4 automatically rotates and resets under the action of the counterweight block 42, and the downward pressure assembly 5 automatically resets with the cooperation of the guide plate 4 and the pressure block 27 to ensure continuous and repeated use.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
