[0002] Sludge treatment is the process of reducing, stabilizing, and rendering harmless sludge. The higher the degree of wastewater treatment, the more sludge residue will be generated. Sludge residue needs to be treated. For modern wastewater treatment plants, sludge treatment and disposal has become the most complex and costly part of the wastewater treatment system operation. The main methods of sludge transportation include pipeline transportation, truck transportation, barge transportation, and combined transportation methods. The method of transportation depends on the nature and quantity of sludge, the sludge treatment method, the transportation distance and cost, and the final disposal and utilization method.

[0029] As shown in Figures 1-5 A sludge conveying device for sludge treatment, comprising a processing box 1, one side of the processing box 1 is provided with a feeding pipe 11, the other side of the processing box 1 is provided with a discharging pipe 12, the height of the discharging pipe 12 is lower than that of the feeding pipe 11, the lower side of the processing box 1 is provided with an inclined surface inclined downward from the feeding pipe 11 to the direction of the discharging pipe 12, the processing box 1 is provided with a crushing mechanism 2 for mud blocks on the inner side of the feeding pipe 11, the processing box 1 is provided with a filtering mechanism 3 on the inner side of the discharging pipe 12, the filtering mechanism 3 and the crushing mechanism 2 are provided with a third filter plate 4 therebetween, the upper side of the third filter plate 4 is connected with a lifting mechanism 5, and the processing box 1 is provided with a garbage discharging port 13.

[0030] The technical scheme of the present embodiment adopts a sludge conveying pump to convey sludge from the feeding port into the processing box 1 for treatment, the processing box 1 is used to filter plastic garbage, household garbage and other garbage that cannot be directly decomposed by microorganisms in the sludge during the conveying process of the sludge, so as to realize that the sludge does not contain garbage after being discharged, the sludge enters the processing box 1 from the feeding pipe 11 and is discharged from the discharging pipe 12, the position of the discharging pipe 12 is lower than that of the feeding pipe 11, the sludge is treated by the crushing mechanism 2 and filtered by the filtering mechanism 3, and then is discharged from the discharging pipe 12 under the action of its own gravity, the combination of the lifting mechanism 5 and the third filter plate 4 is used to lift the plastic garbage, at the same time, the sludge is discharged from the filter holes of the third filter plate 4 and separated from the plastic garbage, the plastic garbage is lifted and discharged from the garbage discharging port 13, so as to realize the separation of the sludge and the garbage.

[0031] Referring to Figure 1 andFigure 3 The crushing mechanism 2 comprises two crushing rollers 21 connected with a transmission mechanism 22, and the two crushing rollers 21 rotate inwardly. In this embodiment, the large pieces of sludge in the sludge are crushed by the crushing rollers 21, so that the crushed large pieces of sludge can be discharged from the discharge pipe 12. The crushing rollers 21 are relatively large in size, and the garbage cannot be entangled with the crushing rollers 21. The crushing rollers 21 are driven to rotate inwardly by the transmission mechanism 22. The output shafts of the two crushing rollers 21 are drivingly connected with gears that are drivingly connected with each other, so that the two crushing rollers 21 are driven to rotate inwardly by the gears.

[0032] Referring to Figure 3 The filtering mechanism 3 comprises a first filter plate 31 and a second filter plate 32. The first filter plate 31 is fixedly connected with the treatment box 1, and the second filter plate 32 is slidingly connected with the treatment box 1. The second filter plate 32 is connected with a reciprocating moving mechanism 6, and the first filter plate 31 is slidingly connected with the second filter plate 32. In this embodiment, the first filter plate 31 and the second filter plate 32 are arranged to enable the second filter plate 32 to reciprocate upwardly relative to the first filter plate 31. The second filter plate 32 slides up and down relative to the side wall of the treatment box 1. Preferably, the second filter plate 32 is slidingly connected with the third filter plate 4, and the reciprocating moving mechanism 6 is used to drive the second filter plate 32 to move up and down. Alternatively, the first filter plate 32 can be slidingly connected with the third filter plate 4.

[0033] Referring to Figures 1-2 and Figure 3 The lifting mechanism 5 comprises connecting ropes 51 connected with the four corners of the third filter plate 4, and winches 52 connected with the treatment box 1 and used to wind and unwind the connecting ropes 51. In this embodiment, the connecting ropes 51 are made of flexible material, and the length of the connecting ropes 51 is controlled by controlling the operation of the winches 52, so as to control the position of the third filter plate 4. The third filter plate 4 is provided with counterweights. When the third filter plate 4 is in a lowered state, the third filter plate 4 will be located at the lower side of the treatment box 1 under the action of its own gravity, so that the connecting ropes 51 remain straight. The two connecting ropes 51 located on the same side are connected with the same winch 52. When the winch 52 is operated, the connecting ropes 51 on one side are simultaneously controlled to rise and fall, so that when the third filter plate 4 reaches the position of the garbage discharge port 13, the two connecting ropes 51 on the side of the garbage discharge port 13 are shortened by controlling the winch 52, so that the third filter plate 4 is inclined to the side of the garbage discharge port 13, thereby enabling the garbage to be poured out. The side of the third filter plate 4 close to the crushing mechanism 2 is provided with an upwardly inclined baffle, which can effectively prevent the garbage from falling from the side of the third filter plate 4.

[0034] Referring to Figures 4-5The reciprocating moving mechanism 6 is assembled on both sides of the second filter plate 32, and the second filter plate 32 is provided with a displacement slot for the reciprocating moving mechanism 6. In the embodiment, the reciprocating moving mechanism 6 is located on both sides of the second filter plate 32, and drives the second filter plate 32 to move up and down, so as to keep the balance of both sides of the second filter plate 32.

[0035] With reference to Figures 4-5 The reciprocating moving mechanism 6 comprises a straight slot plate 61 fixedly connected to one side of the second filter plate 32, a rotating disc 62 assembled on the side wall of the treatment box 1, a motor 63 assembled on the treatment box 1, an output shaft of the motor 63 in transmission connection with the rotating disc 62, and a rocker 64 fixedly connected to the slot of the straight slot plate 61. In the embodiment, the reciprocating moving mechanism 6 is used to drive the second filter plate 32 to move up and down, so as to clean the soil adhered to the first filter plate 31 and the second filter plate 32, avoid the soil and the filter plate 32 from being hardened, and thus affect the passing property of the soil; when the rotating disc 62 rotates, the rocker 64 moves in a circle, and at the same time, the rocker 64 slides in the straight slot plate 61, and the rocker 64 drives the straight slot plate 61 to slide up and down in the process of rotation.

[0036] With reference to Figure 2 The treatment box 1 is hingedly provided with a baffle 14 at the opening of the garbage discharge port 13. In the embodiment, the baffle 114 is used to block the garbage discharge port 13, so that the treatment box 1 keeps a relatively closed state.
