[0023] Example

[0024] Please see Figure 1-4 A secondary filtration device for centrifuged tea oil includes a tea oil centrifugal filter 1, a support 2, and a fixed base 3. Multiple sets of supports 2 are evenly connected to the bottom circumference of the tea oil centrifugal filter 1. The bottom side of each set of supports 2 is connected to the middle of the top side of a fixed base 3. The device also includes a connecting frame 4, a transfer cylinder 5, a guide tube 6, a piston 7, an outer frame 8, a reciprocating motor 9, a threaded rod 10, a threaded pipe 11, an external threaded port 12, a filter screen 13, an internal threaded cover 14, and a discharge pipe 15. The front middle of the tea oil centrifugal filter 1 is connected to the transfer cylinder 5 via the connecting frame 4. The rear side of the cylinder 5 is connected to the output end of the tea oil centrifugal filter 1, which is connected to the input side of the intermediate cylinder 5 via the conduit 6. The inner side of the intermediate cylinder 5 is vertically slidably connected to the outer side of the piston 7. The middle of the top side of the piston 7 is connected to the bottom end of the threaded tube 11. The middle of the top side of the outer frame 8 is connected to the bottom side of the reciprocating motor 9. The output end of the reciprocating motor 9 is connected to the top of the threaded rod 10. The outer wall of the threaded rod 10 is screwed to the inner wall of the threaded tube 11. The bottom side of the intermediate cylinder 5 is connected to the top side of the external threaded port 12. The outer side of the external threaded port 12 is detachably connected to the inner side of the internal threaded cover 14. The filter screen 13 is movably installed inside the internal threaded cover 14, with one side of the bottom of the internal threaded cover 14 connected to the top side of the discharge pipe 15. The filter screen 1 is fixed to the ground by all the fixing seats 3, supported by the bracket 2, and connected by the connecting frame 4 so that the central rotating cylinder 5 is in the front. The filter screen 13 is installed inside the internal threaded cover 14, and the internal threaded cover 14 is screwed closed to the outside of the external threaded opening 12, sealing the lower opening of the central rotating cylinder 5. After the tea oil centrifugal filtration is completed inside the tea oil centrifugal filter 1, the oil is then processed by the reciprocating motor 9. With frame 8 fixed, the threaded rod 10 rotates and is screwed into threaded tube 11. The piston 7 connected to threaded tube 11 is lifted, creating negative pressure inside the intermediate drum 5. The tea oil at the output side of the tea oil centrifugal filter 1 can then be introduced into the intermediate drum 5 through conduit 6. Then, the reciprocating motor 9 reverses and presses the piston 7 down, causing the tea oil inside the intermediate drum 5 to be filtered again through filter screen 13 and discharged through discharge pipe 15. After completion, the inner threaded cover 14 can be screwed off outside the outer threaded opening 12 and the filter screen 13 can be removed for cleaning.

[0025] It also includes a one-way valve 16. A set of one-way valves 16 is provided at the connection between the one-way valve 16 and the transfer cylinder 5 and the connection between the discharge pipe 15 and the internal threaded cover 14. The two sets of one-way valves 16 can respectively realize the one-way flow between the input of the conduit 6 and the output of the discharge pipe 15, avoid backflow and improve reliability.

[0026] It also includes guide sleeves 17, slide bars 18, and limiting plates 19. The middle part of the left and right sides of the top of the piston 7 is connected to the bottom of a set of slide bars 18 respectively. The inner side of the left and right sides of the top of the outer frame 8 is connected to the outer side of a set of guide sleeves 17 respectively. The inner wall of the guide sleeve 17 is slidably connected to the outer wall of the slide bar 18 on the same side. A set of limiting plates 19 are connected to the top side of each set of slide bars 18. By the sliding constraint of the two sets of slide bars 18 inside the guide sleeve 17, the piston 7 can be ensured to move vertically and avoid rotation. Moreover, the corresponding limiting plates 19 limit the movement, thereby improving reliability.

[0027] It also includes a handle 20, with one side of the outer end of the internal threaded cover 14 connected to the inner side of the handle 20; by squeezing the handle 20, force can be applied to connect the internal threaded cover 14 to rotate, improving convenience.

[0030] In summary, when using a secondary filtration device for centrifuged tea oil, all fixed seats 3 are fixed to the ground, the bracket 2 supports the tea oil centrifugal filter 1, and the connecting frame 4 connects to place the intermediate cylinder 5 at the front. The filter screen 13 is installed inside the inner threaded cover 14, and the inner threaded cover 14 is screwed closed to the outside of the outer threaded opening 12, sealing the lower opening of the intermediate cylinder 5. After the centrifugal filtration of tea oil is completed inside the tea oil centrifugal filter 1, the reciprocating motor 9 runs, and under the fixation of the outer frame 8, the threaded rod 10 rotates. The threaded rod 10 is screwed into the threaded tube 11, and the piston 7 connected by the threaded tube 11 is lifted. The piston 7 is slidably constrained by two sets of sliding strips 18 inside the guide sleeve 17, which can ensure the vertical movement of the piston 7 and prevent rotation. The intermediate cylinder is also limited by the corresponding limiting plate 19. 5. Under internal negative pressure, the tea oil at the output side of the tea oil centrifugal filter 1 can be introduced into the intermediate drum 5 through the conduit 6. Then, the reciprocating motor 9 reverses and presses down the piston 7, so that the tea oil inside the intermediate drum 5 is filtered again through the filter screen 13 and discharged through the discharge pipe 15. Two sets of one-way valves 16 can respectively realize one-way flow between the input of the conduit 6 and the output of the discharge pipe 15 to avoid backflow. After completion, the inner thread cover 14 can be rotated by squeezing the handle 20. The inner thread cover 14 can be rotated and screwed off outside the outer thread opening 12 to remove the filter screen 13 for cleaning. In addition, oil can be injected into the inner wall of the threaded pipe 11 through the oil injection nozzle 21 for convenient lubrication and maintenance. After installing the oil injection cap 22 on the outside of the oil injection nozzle 21, the inside of the oil injection nozzle 21 can be sealed and protected to improve reliability.
