[0024] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Refer to the accompanying specification Figures 1-5, the present utility model provides a device for treating and recycling dredged silt, including a bracket 1. A drying box 2 for treating and recycling dredged silt is fixedly penetrated through the top end of the bracket 1. A crushing assembly 3 is fixedly arranged on one side of the drying box 2. The crushing assembly 3 includes a crushing box 301 communicated with the inside of the drying box 2. A communication hole 8 is opened between the crushing box 301 and the drying box 2. The communication hole 8 is located below the pressing plate 4 to prevent the dredged silt from flowing above the pressing plate 4. Two crushing rollers 302 are rotatably arranged inside the crushing box 301. The rear ends of both crushing rollers 302 penetrate through the rear end of the crushing box 301;

[0026] To drive the two crushing rollers 302 to rotate together, meshing gears 303 are fixedly sleeved on both crushing rollers 302. A motor 304 for driving the crushing roller 302 to rotate is fixedly arranged at the rear end of one of the crushing rollers 302. A pressing plate 4 is arranged inside the drying box 2. An installation plate 9 is fixedly arranged at the rear end of the crushing box 301. The motor 304 is fixed on the installation plate 9. Both gears 303 are arranged above the installation plate 9 and are used to support the motor 304 for use;

[0027] Then, a support plate 10 is fixedly arranged between one side of the bottom end of the crushing box 301 and the top end of the bracket 1 to improve the stability of the crushing box 301. A frame 5 is arranged at the bottom of the drying box 2. A filter plate 6 is fixedly arranged inside the frame 5. A lifting assembly 7 for adjusting the heights of the pressing plate 4 and the frame 5 is arranged on the drying box 2.

[0028] When treating the dredged silt, first pour the dredged silt above the crushing box 301. While using the motor 304 to drive one of the crushing rollers 302 to rotate, the other crushing roller 302 rotates together under the meshing of the two gears 303. The two crushing rollers 302 rotate to crush the large-volume garbage in the dredged silt into small volume, which can avoid the large-volume garbage from blocking the crushing box 301 and the drying box 2, and at the same time improve the treatment and recycling efficiency of the dredged silt. After the crushed dredged silt flows into the inside of the drying box 2 through the communication hole 8, then use the lifting assembly 7 to drive the pressing plate 4 to press down. The water in the dredged silt is discharged through the filter plate 6. In actual use, a sewage recycling box can be placed below the frame 5 to recycle and reuse the sewage. After the dredged silt is dried and compressed, it is not only convenient for recycling and reuse, but also can reduce the storage occupied volume.

[0029] Refer to the attached instructions Figures 1-5 , the lifting assembly 7 includes a plurality of hydraulic cylinders 701. One of the hydraulic cylinders 701 is fixedly penetrated through the top end of the drying box 2, and the bottom end of the piston rod of this hydraulic cylinder 701 penetrates through the drying box 2 and is fixedly connected to the top end of the pressing plate 4. The remaining hydraulic cylinders 701 are fixedly embedded on the outer walls of the front and rear sides of the drying box 2, and the bottom ends of the piston rods of the remaining hydraulic cylinders 701 are all fixedly connected to the top end of the frame 5;

[0030] Moreover, telescopic rods 11 are fixedly arranged at the four corners of the outer wall of the drying box 2, and the bottom ends of the telescopic rods 11 are fixedly connected to the top end of the frame 5. The telescopic rods 11 can improve the stability of the frame 5 during lifting and lowering.

[0031] An observation port 12 is formed at the front end of the drying box 2, and tempered glass 13 is fixedly arranged inside the observation port 12, which is convenient for the staff to observe the drying situation of the dredged silt inside the drying box 2.

[0032] Multiple hydraulic cylinders 701 are used to extend and drive the frame 5 to move downward. At the same time, the hydraulic cylinders 701 on the pressing plate 4 are used to drive the pressing plate 4 to move downward, so as to facilitate the removal of the dried dredged silt from the drying box 2. By adopting the lifting method, it is convenient to take the dried dredged silt, which is time-saving and labor-saving in use. At the same time, there is no need to rely on other lifting equipment, which can reduce the use cost.

[0033] Finally, the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
