DETAILED DESCRIPTION

[0021] Example 1

[0022] like Figures 1-4 As shown, the present embodiment provides a centrifugal pulping device for corrugated paper, comprising a centrifugal box 1 , a cover plate 7 , a crushing mechanism and an air pump 8 .

[0023] The upper end of the centrifuge box 1 is open, and the centrifuge box 1 includes an outer shell 101 and an inner shell 102. The inner shell 102 is provided with a plurality of pores 1001, and a cavity is formed between the outer shell 101 and the inner shell 102. The bottom end of the outer shell 101 is connected to a second discharge pipe 10, and a second solenoid valve 12 is installed on the second discharge pipe 10; the bottom end of the centrifuge box 1 is provided with a bracket 2, and the bracket 2 is provided with a rotating drive mechanism for driving the centrifuge box 1 to rotate, and the rotating drive mechanism includes a first servo motor 51, a gear 52 and a gear ring 53, wherein the first servo motor 51 is installed on the side of the support ring 3, the gear 52 is installed on the output shaft of the first servo motor 51, and the gear ring 53 is installed on the outer periphery of the rotating ring 4, and the gear ring 53 is meshed with the gear 52.

[0024] The cover plate 7 is arranged above the centrifugal box 1, and a sealing ring 16 is provided at the bottom end of the cover plate 7. A linear drive mechanism 6 for driving the cover plate 7 to rise and fall is installed on the centrifugal box 1; the crushing mechanism is installed on the cover plate 7, and the crushing mechanism includes a drive motor 13, a stirring shaft 14 and a plurality of crushing blades 15. The stirring shaft 14 is rotatably installed at the bottom end of the cover plate 7, the drive motor 13 is installed on the cover plate 7 and its output shaft is connected to the stirring shaft 14, and the plurality of crushing blades 15 are all installed on the stirring shaft 14; the air pump 8 is installed on the cover plate 7, and the output end of the air pump 8 is arranged below the cover plate 7.

[0025] In this embodiment, corrugated paper and water are put into the interior of the centrifuge box 1, and the linear drive mechanism 6 drives the cover plate 7 to move downward to close the upper end opening of the centrifuge box 1. The rotating ring 4 and the centrifuge box 1 are driven to rotate by the provided rotary drive mechanism. A plurality of balls can be installed at the bottom end of the rotating ring 4 to reduce the resistance of the centrifuge box 1 during rotation. The corrugated paper is crushed by the provided crushing mechanism so that the shredded paper is mixed with water to form pulp. The centrifuge 1 centrifuges the pulp during rotation, and the pulp flows into the cavity through a plurality of fine holes 1001 and is then discharged through the second discharge pipe 10. During the discharge process, the air pump 8 can be started to work, and the air pump 8 pumps external gas into the interior of the centrifuge box 1. A one-way valve is installed on the input pipe of the air pump 8 to only allow gas to enter the interior of the centrifuge box 1. Since the internal pressure of the centrifuge box 1 is increased, the filtration speed of the pulp can be increased, thereby improving the work efficiency.

[0026] Example 2

[0027] like Figure 2 and Figure 3 As shown, a corrugated paper centrifugal pulping device proposed in this embodiment, compared with embodiment 1, in this embodiment, two separation rings 19 are movably arranged in the cavity, and sealing strips can be set on the inner and outer sides of the separation rings 19 to improve the sealing between the separation rings 19 and the inner wall of the cavity. There is a gap between the two separation rings 19, and the two separation rings 19 are fixedly connected. A lifting drive mechanism for driving the two separation rings 19 to move is installed on the centrifugal box 1, and the lifting drive mechanism has a second servo motor 17 and a threaded rod 18. The threaded rod 18 is rotatably installed in the cavity, and the two separation rings 19 are fixedly connected. The rings 19 are all threadedly connected to the threaded rod 18, the second servo motor 17 is installed on the centrifugal box 1 and its output shaft is connected to the threaded rod 18, a water storage box 22 is provided at the lower center of the centrifugal box 1, a rotary joint 20 is installed on the water storage box 22, a water inlet pipe 21 is connected to the rotary joint 20, and a plurality of water pipes 23 are connected to the water storage box 22, and the plurality of water pipes 23 are movable through the bottom end of the centrifugal box 1, and the output end of the water pipe 23 is provided between the two separating rings 19; the bottom end of the inner shell 102 is connected to the first discharge pipe 9, and the first solenoid valve 11 is installed on the first discharge pipe 9.

[0028] The bottom end of the inner shell 102 is a conical bucket structure. The setting of the conical bucket makes it difficult for impurities to accumulate at the bottom end of the inner shell 102.

[0029] In this embodiment, when the pores 1001 are clogged, one end of the water inlet pipe 21 is connected to a water pump, which pumps water into the water inlet pipe 21, and then enters between the two separating rings 19 through the rotary joint 20, the water storage box 22 and multiple water pipes 23 in sequence. Since the cavity between the two separating rings 19 is relatively small, it can play a role in boosting the pressure. Finally, the water is ejected through multiple pores 1001 at corresponding height positions, thereby cleaning the pores 1001. During this process, the two separating rings 19 are driven to move downward synchronously by the provided lifting drive mechanism, and the multiple pores 1001 are cleaned from top to bottom, and the removed residues are discharged through the first discharge pipe 9.

[0030] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
