In the embodiment, a tension spring 82 is fixedly connected to the upper end of the moving tube 71; a tension sensor 83 is fixedly connected to the upper end of the mounting groove 7; the tension spring 82 is fixedly connected with the tension sensor 83.
In the present embodiment, the fixing block 84 is slidably connected to the mounting groove 7; the rotary motor 8 is fixedly connected to the fixed block 84.
Referring to fig. 4 of the drawings, in this embodiment, a blocking plate is fixedly attached to the lower side of the squeeze plug 23; the blocking plate is provided with a circular groove; the moving tube 71 is inserted into the circular groove; the lower end of the blocking plate penetrates through the extrusion frame 22 and is in sliding connection with the extrusion frame 22.
In the invention, the soil humidity sensor 66 is arranged in the extrusion plug 23, so that when the extrusion plug 23 extrudes the sludge, the soil humidity sensor 66 detects the moisture content of the sludge in real time, and when the moisture in the sludge is extruded to be suitable for agglomerating into granular sludge, the extrusion plug 23 stops extruding the sludge;
in the invention, when the extrusion plug 23 moves downwards, the holes 78 on the supporting plate 77 are exposed, so that the water extruded in the sludge is discharged from the holes 78 and the filter screen 26, when the extrusion plug 23 moves upwards, the controller controls the rotary motor 8 to drive the rotary rod 79 to rotate, so that the plugging plate 81 moves to plug the holes 78 on the supporting plate 77, after the water containing suspended sludge enters the extrusion frame 22, the extrusion plug 23 moves downwards for a certain distance, the sludge which subsequently enters the extrusion frame 22 is extruded into mud, then the controller controls the rotary motor 8 to rotate again, the holes 78 are opened, then the clamping electric push rod 73 is controlled to push the moving tube 71 downwards, so that the moving tube 71 moves downwards to the bottom of the extrusion frame 22 along with the supporting plate 77, in the process, mud-like sludge is extruded above the supporting plate 77 through the holes 78, then the extrusion plug 23 moves downwards again, and in the process of moving downwards the extrusion plug 23, the water in the mud above the supporting plate 77 is continuously extruded; after the sludge is extruded by the supporting plate 77, the extrusion plug 23 drives the sludge to move upwards together when moving upwards,
in the invention, the moving pipe 71 pulls the tension sensor 83 through the tension spring 82, so that the tension sensor 83 is stressed by tension, the tension of the tension spring 82 is in direct proportion to the stretched length, therefore, when the supporting plate 77 moves upwards along with the extrusion plug 23, the distance between the supporting plate 77 and the extrusion plug 23 is detected through the tension sensor 83, and when the thickness of the sludge reaches a set value, the pushing block 53 pushes the sludge out of the extrusion frame 22;
in the invention, the blocking plate is arranged on the outer side of the moving pipe 71, so that the part of the diameter width of the moving pipe 71 in the extrusion frame 22 is occupied by the blocking plate, and no sludge exists, thus the situation that when the pushing-out block 53 pushes out the sludge, the sludge exists on two sides of the moving pipe 71 and the pushing-out block 53 cannot push out is avoided;
according to the invention, after sludge is extruded once in the extrusion frame 22 through the support plate 77, the sludge is lifted, after treated water and sludge enter the extrusion frame 22 again, the last sludge is positioned above, but is not in contact with the filter screen 26, the effect of extruding water is affected, after the water and sludge entering the extrusion frame 22 later are extruded into slurry, the support plate 77 moves downwards again, the slurry is extruded above the support plate 77 from the holes 78 on the support plate 77, and the extrusion plug 23 extrudes again.
