Therefore, the sludge needs to be separated by a solid-liquid separator before transportation, and then the sludge can be transported in batches. However, after the conventional solid-liquid separator processes the sludge, there is generally still a certain amount of sewage in the sludge. During the process of large-scale stacking and transportation of the sludge, a certain amount of sewage will drip. Especially during long-distance transportation, it is easy to cause the sewage in the sludge to drip and flow everywhere during transportation, which is extremely likely to cause environmental pollution and affect the transportation effect of the sludge and environmental sanitation.

The height difference between the guide rollers 42 and the drive shafts 41 is also convenient for the sludge to be smoothly introduced below the pressing belt 4 during the transportation through the filter belt 3.

[0021] Both the drive shafts 41 and the guide rollers 42 are movably connected to the bracket 2. The pressing rollers 43 are movably connected to the sliding plates 61.

At the same time, it is avoided that the compression spring 432 disengages from the skateboard 61 during the telescopic process, improving the effect of the compression spring 432 elastically pressing and restricting the skateboard 61.

[0024] The first screw rods 51 are threadedly connected to the four sides of the bracket 2. The lower end of the first screw rod 51 is movably connected to the chassis 1. The upper end of the first screw rod 51 penetrates through the bracket 2 and is connected with a knob 5. The lower end of the first screw rod 51 is connected with a bearing or a rotating seat for movably connecting with the chassis 1, enabling the first screw rod 51 to rotate above the chassis 1. The bracket 2 and the chassis 1 are connected through the first screw rod 51, and the first screw rod 51 is rotated through the knob 5 to adjust the distance between the bracket 2 and the chassis 1.

[0025] An inlet plate 14 is connected to the front of the chassis 1, and an outlet plate 13 is connected to the rear of the chassis 1. One end of the inlet plate 14 is located above one side of the filter belt 3, and the other end of the inlet plate 14 is higher than the filter belt 3 and is connected to the chassis 1. The outlet plate 13 is located between the filter belt 3 and the water tank 12, and the end of the outlet plate 13 facing the filter belt 3 is higher than the other end of the outlet plate 13. The other end of the outlet plate 13 is located outside the water tank 12, so that the untreated sludge can enter above the filter belt 3 through the inlet plate 14, the water in the sludge is removed through the conveyance of the filter belt 3, and the treated sludge can be discharged through the outlet plate 13. The filter belt 3 can be a filter belt or a sieve belt.

[0026] Clamping grooves 31 are arranged on both sides of the filter belt 3. Clamping plates 32 connected to the inlet plate 14 are arranged in the clamping grooves 31. The other end of the clamping plate 32 is hinged with a pushing plate 33 on the side facing the outlet plate 13. A vertical seat 332 is connected above the chassis 1. A second screw rod 331 movably connected to the pushing plate 33 is threadedly connected to the center of the vertical seat 332. The sludge conveyed above the filter belt 3 is limited through the clamping plate 32 located in the clamping groove 31, and the sludge is guided through the pushing plate 33, so that the sludge can automatically fall into the outlet plate 13 through the conveyance of the filter belt 3.

[0028] The sludge waste collection and transportation device allows the preliminarily treated sludge to flow onto the filter belt 3 at the center of the chassis 1 through the guiding plate 14. The external motor drives the power shaft 11 to rotate through the transmission gearbox, and then drives the filter belt 3 to transport the sludge. During the transportation process, the water in the sludge drips through the filter belt 3 into the water tank 12 below; when the sludge is introduced into the center of the bracket 2 and enters below the pressing belt 4, the lower pressure of the compression spring 432 controls the sliding plate 61 to limit and press down the pressing roller 43. The sludge is squeezed and dewatered by the pressing roller 43 and the pressing belt 4, effectively removing the water content in the sludge. At the same time, the clamping plates 32 on both sides of the filter belt 3 limit the sludge, and the sludge is specifically guided through the push plate 33 hinged to it, so that the sludge can accurately fall into the guiding plate 13 and be output; the sewage collected by the water tank 12 is discharged through the connected water outlet pipe 121; the first screw 51 connected between the bracket 2 and the chassis 1 allows the producer to adjust the height of the bracket 2, and the bracket 2 is supported by the adjusting spring 52 in the center of the first screw 51, so as to facilitate controlling the distance between the pressing belt 4 at the center of the bracket 2 and the filter belt 3 at the center of the chassis 1 according to the amount of sludge input by the guiding plate 14 or the water content. The setting of the compression spring 432 and the limiting rod 431 is used to ensure the lower pressure of the sliding plate 61 and the connected pressing roller 43, facilitating the producer to control the force extrusion intensity of the pressing belt on the sludge above the filter belt 3 and ensuring the dewatering effect of the sludge. The adjusting spring 52 and the compression spring 432 are both elastic mechanical components, preferably springs.
