A reaction kettle 5 is penetrated and fixedly connected to the top of the sliding plate 2, so that the reaction kettle 5 can be raised or lowered or adjusted to a fixed position on the workbench.

[0024] On the top of the workbench 1, an extruder 6 is fixedly installed, and a crusher 7 is connected to its discharge end. The discharge end of the crusher 7 is aligned with the feed port of the reactor 5 to ensure that the sugarcane raw materials after extrusion and crushing can directly enter the reactor 5 for subsequent processing. The extruder 6 adopts the press in the patent document CN216579328U, and the crusher 7 adopts the crusher in the patent document CN103614435B.

[0025] A screw rod 16 is provided through the top of the reactor 5, and a sleeve rod 26 is rotatably sleeved on the outer wall of the screw rod 16. A plurality of stirring rods 32 are evenly distributed on the outer wall of the sleeve rod 26 for fully stirring the materials in the reactor.

[0026] A first motor 27 is installed at the bottom of the reaction kettle 5 through the first fixing frame 12. The output end of the motor is connected to the sleeve rod 26 and the screw rod 16 respectively, and the synchronous rotation of the two is achieved through the transmission device.

[0027] A fixing ring 19 is fixedly provided in the feed port of the reactor 5, and a filter cover 20 is connected to the bottom thereof. A filter disc 21 is fixedly installed on the inner wall of the bottom end of the filter cover 20, and the diameter of the filter disc is slightly smaller than the fixing ring 19 to avoid being stuck during the lifting process.

[0028] The filter disc 21 is connected to the screw rod 16 by threads. When the screw rod 16 rotates, the filter disc 21 can be driven to move up and down, thereby collecting and releasing the bagasse.

[0029] A first electromagnetic clutch 29 is also installed at the bottom of the reactor 5, and its output end is fixedly connected to the screw 16. In addition, a rotating shaft 28 is rotatably provided through the bottom of the reactor 5, and two second gears 31 are fixedly sleeved on the outer wall of the rotating shaft 28.

Through such a gear transmission structure, the first motor 27 is used to synchronously drive the screw rod 16 and the sleeve rod 26.

[0031] A conical cover 25 is rotatably sleeved on the outer wall of the sleeve rod 26. The conical cover 25 is fixedly mounted on the bottom wall of the reaction kettle 5, and the discharge port of the reaction kettle 5 corresponds to the bottom end of the conical cover 25, so as to discharge the sugarcane extract after filtration and stirring.

[0032] The outer wall of the filter disc 21 is evenly provided with a plurality of rectangular openings 35 , and a stop bar 22 is rotatably arranged in each rectangular opening 35 . A stop block 36 is fixedly arranged on the inner side of the stop bar 22 , and the stop blocks 36 are in close contact with the surface of the filter disc 21 .

[0033] When the stop block 36 contacts the filter plate 21, the plurality of baffles 22 are squeezed to naturally form an upwardly inclined conical structure. This design helps to retain bagasse during the filtering process while allowing sugarcane juice to pass through.

[0034] When the filter plate 21 rises with the screw 16 and moves to above the fixing ring 19, the blocking bar 22 automatically opens due to gravity due to the loss of support from the filter cover 20, thereby allowing the filtered bagasse to fall.

[0035] A second rotating ring 23 is also rotatably provided on the top of the filter disc 21, and the ring is slidably sleeved on the screw 16. A second scraper 24 is fixedly provided on the outer wall of the second rotating ring 23 for cleaning the residue on the top of the filter disc 21 during its ascending process.

[0037] The outer wall of the sliding rod 9 is sleeved with a second spring 11, and the two ends of the second spring 11 are respectively fixedly connected to the support frame 8 and the side of the pressure plate 10 close to each other to ensure that the pressure plate 10 can maintain a certain position when there is no external force.

[0038] When the reaction kettle 5 moves with the sliding plate 2 to the bottom of the support frame 8 and drives the filter plate 21 to move upward to contact the pressure plate 10, the pressure plate 10 will squeeze the bagasse between the multiple baffles 22 to further extract the sugarcane juice or compress the volume of the bagasse.

[0039] A receiving tray 14 is fixedly sleeved on the top outer wall of the reactor 5, and its diameter is larger than the total length of the baffle bars 22 after opening to ensure that the bagasse and other impurities falling from between the baffle bars 22 can be fully received, and an overflow hole is provided on the outer wall of the reactor 5 above the receiving tray 14 to facilitate the squeezed juice to flow into the reactor 5.

[0040] A first rotating ring 15 is rotatably provided on the outer wall of the receiving tray 14 . A discharge pipe 18 is fixedly connected to one side of the reaction kettle 5 . The top end of the discharge pipe 18 is communicated with the inside of the receiving tray 14 .

[0041] The bottom end of the discharge pipe 18 penetrates the sliding plate 2 so as to discharge the collected impurities.

[0042] The workbench 1 is provided with a transmission member for automatically driving the first rotating ring 15 to rotate when the reaction kettle 5 moves to below the support frame 8 .

[0043] A first scraper 17 is fixedly provided on the first rotating ring 15, and the scraper is in close contact with the inner wall of the receiving tray 14. As the first rotating ring 15 rotates, the first scraper 17 scrapes the impurities collected in the receiving tray 14 into the discharge pipe 18, thereby automatically cleaning and discharging the impurities.

[0044] A second fixing frame 37 is fixedly installed on one side of the workbench 1 , and a roller 38 is rotatably provided on the fixing frame. The position of the roller 38 corresponds to the first rotating ring 15 to ensure that when the reactor 5 moves to the bottom of the supporting frame 8 , the first rotating ring 15 can contact the roller 38 .

One of the output ends is connected to the rotating shaft of the roller 38 through a synchronous wheel 39 and a synchronous belt 40. The synchronous wheel 39 is installed on the rotating shaft of the roller 38 and the outer wall of the output end of the dual-axis motor 41, and the synchronous belt 40 is wound between the two synchronous wheels 39 to achieve synchronous transmission of power.

[0046] When the reactor 5 moves with the sliding plate 2 to the bottom of the support frame 8 and the first rotating ring 15 contacts the roller 38, the dual-axis motor 41 is started and drives the roller 38 to rotate through the synchronous belt 40, and then utilizes the friction between the roller 38 and the first rotating ring 15 to drive the first rotating ring 15 and the first scraper 17 fixed thereon to rotate, so as to scrape and discharge impurities in the docking tray 14.

[0047] The present application can be used in the field of sugarcane extract processing, and can also be used in other fields applicable to the present application.

[0051] When the connecting frame 34 contacts the bottom of the fixing ring 19 , the filter plate 21 is located just above the fixing ring 19 . This design not only limits the position of the filter plate 21 , but also ensures its stability during the lifting process.

[0052] Two guide rods 3 are fixedly installed inside the workbench 1 . The two guide rods 3 respectively penetrate two sides of the sliding plate 2 to provide guidance and support for the lifting and lowering of the sliding plate 2 .

[0053] The outer wall of the guide rod 3 is sleeved with a first spring 4, and both ends of the first spring 4 are fixedly connected to the sliding plate 2 and the side of the workbench 1 close to each other, so as to keep the sliding plate 2 in the initial position when no external force is required.

[0054] The second electromagnetic clutch 42 is fixedly installed at the bottom of the workbench 1, and its input end is fixedly connected to the other unused output end of the dual-axis motor 41. The output end of the second electromagnetic clutch 42 is fixedly sleeved with a winding roller 43, and the outer wall of the winding roller 43 is fixed and wound with a pull rope 13.

The rotation of the rotating shaft 28 can drive the second gear 31 to rotate. During the rotation of the second gear 31, the sleeve rod 26 can be driven to rotate through the first gear 30. The rotation of the sleeve rod 26 can drive the multiple stirring rods 32 to rotate for stirring reaction. After the reaction is completed, the dual-axis motor 41 is started to rotate. The rotation of the dual-axis motor 41 can drive the input end of the second electromagnetic clutch 42 to rotate, and the second electromagnetic clutch 42 is started, which can drive the output end to rotate through the input end, and can drive the winding roller 43 to rotate.

During the reeling process, the sliding plate 2 is pulled to move, which can drive the reactor 5 to move to the bottom of the support frame 8, and make the fixed ring 19 correspond to the pressure plate 10 until the first rotating ring 15 contacts the roller 38; Then start the first motor 27 and the first electromagnetic clutch 29. The rotation of the first motor 27 can also drive the input end of the first electromagnetic clutch 29 to rotate through the second gear 31 and the first gear 30 below. The rotation of the input end can drive the output end to rotate, which can drive the screw 16 to rotate. The rotation of the screw 16 can drive the filter plate 21 to move upward. The upward movement of the filter plate 21 can drive the impurities inside to move upward. During the upward movement, the pressure plate 10 can be located between the multiple baffles 22. Continuing to move upward can cooperate with the pressure plate 10 to squeeze the impurities on the filter plate 21, squeeze out the juice inside, and when the impurities are completely squeezed out, After being pressed, continuing to move upward can drive the pressure plate 10 to move upward and compress the second spring 11. At the same time, the filter plate 21 can drive the bottom end of the filter cover 20 to flip upward from the inside during the upward movement, until the filter cover 20 moves to the top of the fixed ring 19. At this time, the baffle 22 can be automatically opened, and the impurities will fall on the receiving plate 14 under pressure. The screw 16 can drive the second rotating ring 23 to rotate during the rotation process. The rotation of the second rotating ring 23 can drive the second scraper 24 to rotate, scrape the impurities on the filter plate 21, and then discharge the extracted juice through the discharge pipe 18 on one side of the reactor 5, and then continue processing; After the impurities fall on the receiving tray 14, the double-axis motor 41 is started, and the double-axis motor 41 can drive the roller 38 to rotate through the synchronous wheel 39 and the synchronous belt 40. The rotation of the roller 38 can drive the first rotating ring 15 to rotate through the friction between the roller 38 and the first rotating ring 15. The rotation of the first rotating ring 15 can drive the first scraper 17 to rotate, and the impurities on the receiving tray 14 can be pushed into the discharge pipe 18 for discharge; After the impurities and juice are completely discharged, the dual-axis motor 41 is started to rotate in the reverse direction and the second electromagnetic clutch 42 is started to drive the winding roller 43 to rotate in the reverse direction, and the pull rope 13 is released.
