This phenomenon has become a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-3The present invention provides a technical solution: a centrifuge for starch processing, comprising a centrifuge shell 1, a fixed frame 2 and a feeding bin 3 fixedly connected to the top of the centrifuge shell 1, a drive motor 4 fixedly connected to the top of the fixed frame 2, a drive shaft 5 fixedly connected to the output shaft of the drive motor 4 via a coupling, a support frame 6 fixedly connected to the outer wall of the drive shaft 5, a stirring blade 7 fixedly connected to the bottom of the drive shaft 5, a guide bin 8 fixedly connected to the outer wall of the support frame 6, a support shaft 9 movably connected to the bottom inner wall of the centrifuge shell 1, a filter cylinder 10 fixedly connected to the top of the support shaft 9, and a connecting frame 11 fixedly connected to the top of the filter cylinder 10.

[0023] A driven shaft 12 is movably connected to the inner wall of the connecting frame 11. A driven gear 13 is fixedly connected to the top of the driven shaft 12, and a cleaning roller 14 is fixedly connected to the bottom of the driven shaft 12. A fixed gear ring 17 is fixedly connected to the top inner wall of the centrifuge housing 1. A first discharge pipe 15 is fixedly connected to one side outer wall of the centrifuge housing 1, and a second discharge pipe 16 is fixedly connected to the other side outer wall of the centrifuge housing 1. The centrifuge housing 1, the fixed frame 2, the feeding bin 3, the drive motor 4, the drive shaft 5, the support frame 6, the stirring blade 7, the guide bin 8, and the support shaft 9 are all provided. The filter cylinder 10, connecting frame 11, driven shaft 12, driven gear 13, cleaning roller 14, first discharge pipe 15, second discharge pipe 16, and fixed gear ring 17 facilitate the simultaneous rotation of the filter cylinder 10 and the stirring blade 7, thereby promoting the stirring of starch during centrifugal filtration. This results in a uniform distribution of the starch mixture, improving sieving efficiency. Furthermore, it facilitates the simultaneous cleaning of the inner wall of the centrifuge casing 1 and the outer wall of the filter cylinder 10, thus solving the problem of wall adhesion that can affect centrifugal operation.

[0024] Preferably, the top of the feed hopper 3 is connected to the top of the centrifuge housing 1, and the bottom of the feed hopper 3 extends into the interior of the guide hopper 8. Specifically, the bottom of the guide hopper 8 extends into the interior of the filter cylinder 10, which facilitates the effective pouring of the starch mixture into the interior of the filter cylinder 10.

[0025] Preferably, the support frame 6 is arranged in a "*" shape when viewed from above, and the support frame 6 is welded to the feed bin 8. Specifically, there is a gap between the top of the support frame 6 and the bottom of the feed bin 3, so as to ensure that the feed bin 8 can be effectively rotated by the support frame 6 and avoid affecting the feeding operation during the rotation.

[0026] Preferably, the outer wall of the guide bin 8 is provided with toothed blocks at equal angles, and the guide bin 8 meshes with the driven gear 13 through the toothed blocks, thereby facilitating the guide bin 8 to drive the driven gear 13 to rotate.

[0027] Preferably, the filter cartridge 10 is rotatably connected to the centrifuge housing 1 via the support shaft 9, and the support shaft 9 is a hollow structure. Specifically, the first discharge pipe 15 is distributed in an "L" shape, and the top of one end of the first discharge pipe 15 is connected through the support shaft 9 and communicates with the bottom of the filter cartridge 10.

[0028] Preferably, the driven shaft 12 passes through the connecting frame 11 via a bearing, and the driven shaft 12 is rotatably connected to the connecting frame 11 via the bearing. Specifically, the connecting frame 11 is arranged in an "L" shape, which facilitates effective support of the driven shaft 12 via the connecting frame 11.

[0029] Preferably, the driven gear 13 is distributed at equal angles along the axial center line of the fixed gear ring 17, and the driven gear 13 meshes with the fixed gear ring 17, thereby facilitating the driving of the driven gear 13 to revolve.

[0030] Preferably, the cleaning roller 14 is in close contact with the inner wall of the centrifuge housing 1, and the cleaning roller 14 forms a rotating structure with the centrifuge housing 1 through the driven shaft 12. Specifically, the distance between the inner wall of the centrifuge housing 1 and the axial center line of the driven gear 13 and the distance between the outer wall of the filter cylinder 10 and the axial center line of the driven gear 13 are the same, thereby ensuring that the cleaning roller 14 scrapes the inner wall of the centrifuge housing 1 and the outer wall of the filter cylinder 10 respectively during its rotation and revolution.

[0031] In use, first start the drive motor 4, which drives the drive shaft 5 to rotate. The drive shaft 5 then drives the support frame 6 to rotate, which in turn drives the guide bin 8 to rotate. The guide bin 8, through the toothed block, drives the driven gear 13 to rotate. The driven gear 13 revolves by meshing with the fixed gear ring 17, which in turn drives the filter cylinder 10 to rotate via the driven shaft 12. At the same time, the drive shaft 5 drives the stirring blade 7 to rotate inside the filter cylinder 10, which helps to make the starch mixture more uniform. This effectively improves the efficiency of starch separation by centrifugal force in the filter cylinder 10. While rotating on its own axis and revolving around the centrifugal force, the driven shaft 12 drives the cleaning roller 14 to rotate around the axial center line of the driven gear 13 and revolve around the outer wall of the filter cylinder 10 and the inner wall of the centrifuge housing 1. This allows the cleaning roller 14 to scrape and clean the inner wall of the centrifuge housing 1 and the outer wall of the filter cylinder 10, thus avoiding the situation where the separated starch sticks to the wall and causes incomplete discharge, and also avoiding the clogging of the mesh of the filter cylinder 10, which would affect the centrifugal screening operation.
