[0002] Sludge treatment is the process of reducing, stabilizing and rendering sludge harmless by concentrating, tempering, dehydrating, stabilizing, drying or incinerating the sludge. Traditional sludge dehydration treatment often adopts gravity concentration, squeeze filtration, centrifugal filtration and the like. In the centrifugal filtration method, the sludge is generally poured into a dehydration cylinder, and the centrifugal force is generated by the high-speed rotation of the dehydration cylinder to throw the water in the sludge out of the dehydration cylinder. However, since the sludge is easily adsorbed on the inner wall of the dehydration cylinder, the dehydration holes are blocked and cannot be cleared in time. During the rotation of the dehydration cylinder, the dehydration effect is poor. Therefore, those skilled in the art provide a waste sludge dehydration treatment and recovery device to solve the problems raised in the above background technology. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. It should be noted that, unless otherwise clearly specified and limited, the terms "install", "connect", and "set" should be understood in a broad sense. For ordinary technicians in this field, the specific meanings of the above terms in this patent can be understood according to specific circumstances.

[0021] Reference Figures 1-4 A waste sludge dewatering treatment and recovery device includes a treatment box 1. The inner walls of both sides of the treatment box 1 are rotatably connected with a rotating shaft 15. A roller 13 is fixed between the two rotating shafts 15 by bolts. The outer wall of the roller 13 is provided with multiple leakage holes 12. A motor 2 is fixed to the outer wall of one side of the treatment box 1 by bolts, and one end of the output shaft of the motor 2 passes through the treatment box 1 and is fixed to one of the rotating shafts 15. When the motor 2 is started, the motor 2 rotates to make the rotating shaft 15 drive the roller 13 to rotate, and the rotation of the roller 13 generates centrifugal force. At this time, the sludge in the treatment box 1 is discharged. The liquid in the part is thrown out through multiple leakage holes 12 to complete the dehydration of the sludge. Rubber plates 19 are provided on the inner walls of both sides of the processing box 1, and the rubber plates 19 are in contact with the drum 13. A driving component is provided in the processing box 1 to make the rubber plates 19 move back and forth, so that when the drum 13 rotates, the rubber plates 19 slap the surface of the drum 13 to shake off the sludge adsorbed on the drum 13. The driving component controls the rubber plates 19 to repeatedly slap the drum 13, so that dehydration can be achieved while cleaning the inner wall of the drum 13.

[0022] In the present invention, the driving assembly includes a cam 14, a push rod 16, a spring 17, and a slide rod 18. Both sides of the processing box 1 are connected to the two push rods 16 through the sliding connection. One end of the push rod 16 is fixed with a connecting plate 6 by a bolt, and the connecting plate 6 is located on the outside of the processing box 1. Both sides of the processing box 1 are connected to the two slide rods 18 through the sliding connection, and one end of the slide rod 18 is fixed to the connecting plate 6, and the other end is fixed to the rubber plate 19. The circumferential outer walls of the multiple slide rods 18 are sleeved with springs 17, and the two ends of the spring 17 are respectively fixed to the slide rod 18 and the processing box 1. The circumferential outer wall of the shaft 15 is keyed to a cam 14, and the cam 14 is in contact with one end of the push rod 16. The rotation of the rotating shaft 15 drives the cam 14 to rotate, and the rotation of the cam 14 squeezes the push rod 16. At this time, the push rods 16 on both sides of the cam 14 drive the connecting plate 6 to move outward, and the sliding rod 18 drives the rubber plate 19 to move outward and disengage from the roller 13. The spring 17 is forced to contract. When the cam 14 rotates to disengage from the push rod 16, the spring 17 rebounds and resets, and the sliding rod 18 drives the rubber plate 19 to reset, and the rubber plate 19 hits the roller 13.

[0023] In the utility model, a feed port is provided on one side of the drum 13, and a blocking door 20 is slidably connected to the feed port. A notch is provided on the top of the processing box 1, and a sealing plate 8 is rotatably connected to the notch. By opening the sealing plate 8 and the blocking door 20, the sludge can be poured into the drum 13, and then the blocking door 20 and the sealing plate 8 are closed.

[0024] In the present invention, a supporting plate is fixed to the inner wall of the processing box 1 near the bottom by bolts, and a plurality of guide holes 11 are opened on the supporting plate. A drainage bucket 4 is fixed to the bottom of the processing box 1 by bolts, and the bottom of the drainage bucket 4 is fixedly connected to a drainage pipe 3. The thrown-out liquid can fall into the drainage bucket 4 through the guide holes 11 and then be discharged through the drainage pipe 3.

[0025] In the utility model, an electric telescopic rod 7 is fixed to the outer wall of one side of the processing box 1 by bolts. One end of the electric telescopic rod 7 passes through the processing box 1 and is fixed with a push plate 10 by bolts, and the push plate 10 is in contact with the surface of the supporting plate. A discharge port is provided on one side of the processing box 1, and a baffle 5 is rotatably connected to the discharge port. When the sludge is dehydrated, the blocking door 20 is opened, and the sludge can fall onto the supporting plate through the blocking door 20. The baffle 5 is opened and the electric telescopic rod 7 is started. The electric telescopic rod 7 extends to extend the push plate 10, and the push plate 10 pushes the sludge along the surface of the supporting plate, and pushes the sludge out of the discharge port to the outside of the processing box 1.

[0026] In the present invention, a plurality of supporting legs 9 are fixed to the bottom outer wall of the processing box 1 by bolts.

[0027] Working principle: When the sludge needs to be dehydrated, open the sealing plate 8 and the blocking door 20, pour the sludge into the drum 13, then close the blocking door 20 and the sealing plate 8, start the motor 2, and the motor 2 rotates to make the shaft 15 drive the drum 13 to rotate, and the rotation of the drum 13 generates centrifugal force. At this time, the liquid inside the sludge is thrown out through multiple leak holes 12, completing the dehydration of the sludge. The thrown-out liquid falls into the drainage bucket 4 through the guide hole 11, and then is discharged through the drainage pipe 3. During the rotation of the shaft 15, the cam 14 is driven to rotate, and the rotation of the cam 14 squeezes the push rod 16. At this time, the push rods 16 on both sides of the cam 14 drive the connecting plate 6 to move outward, and the sliding rod 18 drives the rubber plate 19 to move outward and disengage from the drum 13. The spring 17 is forced to shrink. When the cam 14 rotates to disengage from the push rod 16, the spring 17 rebounds and resets, and the sliding rod 18 drives the rubber plate 19 to reset. The rubber plate 19 hits the drum 13. At this time, the drum 13 vibrates, and then the sludge adhering to the inner wall of the drum 13 is shaken off. As the drum 13 continues to rotate, the rubber plate 19 repeatedly beats the drum 13, which can achieve dehydration while cleaning the inner wall of the drum 13.

[0028] In this application, the structures and connection relationships that are not described in detail are all prior art, and their structures and principles are well-known technologies and will not be described in detail here.

[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
