Detailed implementation mode

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present invention.

[0030] Please refer to Figures 1-8 , the present invention provides a carotene extraction filter residue separation and filtration device, including a cylinder shell 1, and a top shell 2 is fixedly connected to the top end of the telescopic cylinder shell 1. A circular hole is opened at the bottom end of the cylinder shell 1, and an annular groove-shaped structure is designed at the inner side position, so that the carrot filter residue and the carrot-extracted juice can be fully separated. The top shell 2 is connected to the cylinder shell 1, and an opening is provided on the side of the top shell 2, so that the driven wheel 3 can drive the internal structure to operate through the opening.

[0031] A driven wheel 3 is rotatably connected inside the top shell 2. The driven wheel 3 is to prevent the driven wheel 3 from shifting during rotation. A filter cylinder 4 is fixedly connected to the bottom end of the driven wheel 3. The filter cylinder 4 is the core component for separating and filtering the carrot filter residue. The filter holes on its cylinder wall are designed to allow the water in the carrot filter residue to be discharged under the action of centrifugal force, while the filter residue is intercepted inside the filter cylinder 4. The bottom end of the filter cylinder 4 is movably connected to the inner wall of the cylinder shell 1, and the bottom surface of the filter cylinder 4 contacts the concave position at the bottom end of the cylinder shell 1 for sealed rotation, so as to ensure the stability of the filter cylinder 4 during high-speed rotation.

[0032] A motor 5 is fixedly connected to the side wall of the cylinder shell 1. As the power source of the entire device, the motor 5 can convert electrical energy into mechanical energy and provide stable rotational power for the driving wheel 6. The driving end of the motor 5 is fixedly connected to the driving wheel 6. The driving wheel 6 rotates under the drive of the motor 5. The external teeth of the driving wheel 6 and the external teeth of the driven wheel 3 are meshed and connected. Through the way of gear meshing transmission, the rotational power of the driving wheel 6 is transmitted to the driven wheel 3 to achieve effective power transmission. At the same time, gear transmission has the advantages of accurate transmission ratio and high efficiency, ensuring the stability of the rotational speed of the driven wheel 3.

[0033] The bottom side position of the bottom end of the filter cylinder 4 is rotatably connected to the bottom cover 14 through a torsion spring hinge. The bottom cover 14 plays a role in closing the bottom of the filter cylinder 4 during the operation of the filter cylinder 4 to prevent the filter residue from leaking from the bottom. A discharge pipe 28 is fixedly connected to the front bottom end of the cylinder shell 1. The discharge pipe 28 is used to collect and discharge the carotene juice separated from the filter holes of the filter cylinder 4. Its inclined setting and diversion structure design can make the juice flow out smoothly and avoid remaining in the cylinder shell 1.

[0034] Reference Figures 4-6, a conveying member, and a support frame 7 fixedly connected to the top shell 2. A multi-stage hydraulic cylinder 8 is fixedly connected to the middle of the support frame 7. The support frame 7 plays a role in supporting the multi-stage hydraulic cylinder 8, can bear the pressure generated during the operation of the multi-stage hydraulic cylinder 8, and ensure the stable operation of the multi-stage hydraulic cylinder 8. The multi-stage hydraulic cylinder 8 can control its telescopic length through a hydraulic system, thereby realizing the lifting control of the first pressing block 9 to meet the extrusion requirements for filter residues at different stages.

[0035] The driving end of the multi-stage hydraulic cylinder 8 penetrates through the top shell 2 and is fixedly connected to the first pressing block 9. Driven by the multi-stage hydraulic cylinder 8, the first pressing block 9 can move up and down in the filter cylinder 4 to perform an extrusion operation on the filter residue. It has a certain gap with the inner wall of the filter cylinder 4 to ensure that there will be no excessive friction with the filter cylinder 4 during the movement, and at the same time can effectively extrude the filter residue. A second pressing block 10 is slidably connected to the outside of the first pressing block 9. The second pressing block 10 can slide outside the first pressing block 9. When extruding the filter residue, due to its own gravity and the elastic force of the first spring 12, it can contact the filter residue prior to the first pressing block 9 to achieve the preliminary extrusion of the filter residue and improve the juice extraction efficiency.

[0036] The second pressing block 10 is slidably connected to the inner wall of the filter cylinder 4. This sliding connection method enables the second pressing block 10 to remain stable when moving in the filter cylinder 4 and at the same time fit the inner wall of the filter cylinder 4 to ensure the uniformity of the extrusion of the filter residue. Four corners of the inside of the second pressing block 10 are fixedly connected with connecting rollers 11. The connecting rollers 11 play a role in connecting the second pressing block 10 and the first spring 12. At the same time, during the sliding process of the second pressing block 10, the friction with the first pressing block 9 can be reduced to ensure the smoothness of the sliding. The top end of the connecting roller 11 is fixedly connected with the first spring 12. The first spring 12 has elasticity and can provide elastic support for the second pressing block 10, enabling it to automatically adjust the pressure according to the resistance of the filter residue when extruding the filter residue, ensuring the effective extrusion of the filter residue and not damaging the filter cylinder 4 due to excessive pressure.

[0037] Hole grooves 13 are formed at four corners of the bottom end of the first pressing block 9. The hole grooves 13 are used to accommodate the connecting rollers 11, providing space for the sliding of the connecting rollers 11 to ensure the smooth relative sliding between the first pressing block 9 and the second pressing block 10. The conveying member includes a feeding hopper 15. The function of the feeding hopper 15 is to receive the carrot filter residue and guide it into the filter cylinder 4. Its half-funnel-shaped structural design enables the filter residue to flow in smoothly and avoids the accumulation and blockage of the filter residue.

[0038] Reference Figure 6 、 Figure 7 , the bottom end of the feeding hopper 15 is fixedly connected to the top end of the top shell 2. This connection method ensures the stability of the feeding hopper 15 and prevents it from shaking during the process of conveying the filter residue. A telescopic pipe 16 is fixedly connected to the bottom end of the feeding hopper 15. The telescopic pipe 16 has telescopic properties and can adjust its length according to different operating states of the device to accurately feed the filter residue into the filter cylinder 4. At the same time, it can be shortened when not in use to save space.

[0039] A hole 17 is provided at the top of the first briquette 9, and the hole 17 is for the telescopic pipe 16 to pass through, so that the filter residue can enter the inside of the filter cylinder 4 through the telescopic pipe 16. Its size is adapted to the telescopic pipe 16 to ensure the tightness during the transportation of the filter residue and prevent the filter residue from leaking. The outside of the connecting roller 11 is slidably connected to the inner wall of the hole 17, so that when the first briquette 9 and the second briquette 10 slide relative to each other, the connecting roller 11 can move along the inner wall of the hole 17 to ensure the stability of the movement of the second briquette 10.

[0040] The top end of the first spring 12 is fixedly connected to the inner wall of the hole 17, fixing the first spring 12 in the hole 17 so that it can provide a stable elastic support for the second briquette 10. The outside of the telescopic pipe 16 is slidably connected to the inner wall of the hole 17 to ensure that the telescopic pipe 16 can freely expand and contract in the hole 17, and at the same time realize the smooth transportation of the filter residue from the feed hopper 15 to the filter cylinder 4.

[0041] A switching valve 18 is provided at the top end of the second briquette 10. The switching valve 18 is used to control the on-off between the telescopic pipe 16 and the filter cylinder 4. It is opened when feeding the filter residue into the filter cylinder 4 to allow the filter residue to enter smoothly; it is closed when the filter cylinder 4 is working to prevent the filter residue or juice from overflowing from the telescopic pipe 16, ensuring the safety and stability of the operation of the device. The top end of the switching valve 18 is installed at the bottom end of the telescopic pipe 16. This installation method ensures the tight connection between the switching valve 18 and the telescopic pipe 16 and ensures the effectiveness of the switching operation.

[0042] Reference Figure 5 、 Figure 8 At the middle part of the bottom end of the bottom cover 14, a telescopic member for abutting against the bottom cover 14 is provided. The telescopic member includes a rotating block 19. The bottom end of the rotating block 19 is rotatably connected to the middle part of the bottom end of the bottom cover 14. The rotating block 19 can rotate at the bottom of the bottom cover 14 to realize the support and release of the bottom cover 14 by rotation, thereby controlling the opening and closing of the bottom cover 14. A limiting rod 20 is fixedly connected to the end of the rotating block 19 away from the bottom cover 14. The limiting rod 20 is used to limit the displacement of the second spring 21 and at the same time provide guidance for the rotation of the rotating block 19 to ensure the accuracy of the rotation of the rotating block 19.

[0043] A second spring 21 is sleeved outside the limiting rod 20. The second spring 21 has elasticity and can provide a reset elastic force for the rotating block 19. When the bottom cover 14 is closed, the rotating block 19 tightly abuts against the bottom cover 14 to ensure the tightness of the bottom cover 14; when the bottom cover 14 needs to be opened, it can store and release energy to assist the rotation of the rotating block 19. An anti-disengagement tube 22 is slidably connected to the outside of the second spring 21. The anti-disengagement tube 22 is used to prevent the second spring 21 from disengaging from the limiting rod 20 during the telescopic process, ensuring the stability of the operation of the second spring 21 and at the same time providing a certain support and protection for the second spring 21.

[0044] One end of the second spring 21 is fixedly connected to one end of the rotary block 19 away from the bottom cover 14, and the other end is fixedly connected to one end of the anti - detachment tube 22 close to the rotary block 19. This connection method enables the second spring 21 to effectively provide elastic force for the rotary block 19 and realize the control of the bottom cover 14. At the rear side of the bottom end of the anti - detachment tube 22, an adjusting wheel 23 is fixedly connected. Through the cooperation with other components, the adjusting wheel 23 can convert the movement of the first pressing block 9 into the rotation of the rotary block 19, so as to realize the opening and closing control of the bottom cover 14. Its gear structure design ensures the accuracy of transmission.

[0045] On the side wall of the cylinder shell 1, there is a limiting part for positioning the adjusting wheel 23. The limiting part includes an auxiliary plate 24. The left side of the auxiliary plate 24 is fixedly connected to the side wall of the cylinder shell 1. The auxiliary plate 24 plays a role in supporting and positioning the adjusting wheel 23, can bear the force generated by the adjusting wheel 23 during operation, and ensures the stability of the operation of the adjusting wheel 23. At the bottom end of the front side of the auxiliary plate 24, a supporting roller 25 is fixedly connected. The supporting roller 25 provides rotational support for the adjusting wheel 23, enabling the adjusting wheel 23 to rotate freely outside it. The middle part of the adjusting wheel 23 is rotatably connected to the outside of the supporting roller 25, and the bottom end of the anti - detachment tube 22 is rotatably connected to the outside of the supporting roller 25. This connection method ensures that the adjusting wheel 23 and the anti - detachment tube 22 can rotate stably on the supporting roller 25 and realizes the effective cooperation between various components.

[0046] At the top of the first pressing block 9, there is a pushing part for opening the bottom cover 14. The pushing part includes a U - shaped rod 26. One end of the U - shaped rod 26 close to the top shell 2 is fixedly connected to the top of the first pressing block 9. The U - shaped rod 26 moves as the first pressing block 9 moves up and down, converting the linear motion of the first pressing block 9 into the linear motion of the tooth space 27, so as to realize the control of the adjusting wheel 23. There is a tooth space 27 in the middle of the U - shaped rod 26. The teeth on the side of the tooth space 27 close to the cylinder shell 1 are meshed with the external teeth of the adjusting wheel 23. Through the meshing transmission between the tooth space 27 and the adjusting wheel 23, the linear motion of the U - shaped rod 26 is converted into the rotational motion of the adjusting wheel 23, and then drives the rotary block 19 to rotate, realizing the opening of the bottom cover 14 and ensuring the stability of the opening operation of the bottom cover 14.

[0047] The outside of the U - shaped rod 26 is slidably connected to the middle part of the top shell 2, and the outside of the U - shaped rod 26 is slidably connected to the inner wall of the auxiliary plate 24. This sliding connection method ensures the stability of the U - shaped rod 26 during movement, enabling it to accurately transmit the movement of the first pressing block 9 to the tooth space 27 and the adjusting wheel 23. The bottommost round rod of the U - shaped rod 26 contacts the teeth of the adjusting wheel 23 at the initial stage. Before the tooth space 27 contacts the adjusting wheel 23, the side wall of the U - shaped rod 26 will contact the adjusting wheel 23 to prevent the adjusting wheel 23 from rotating.

[0048] Working principle: The user pours the carrot residue into the feeding hopper 15, and sends the carrot residue into the interior of the filter cylinder 4 through the telescopic pipe 16 and the opened hole 17. After all the carrot residue is sent in, start the motor 5 to drive the teeth of the driving wheel 6 to engage with the external teeth of the driven wheel 3, so that the driven wheel 3 drives the filter cylinder 4 and the bottom cover 14 to rotate at high speed to generate centrifugal force, so that the remaining water in the carrot residue is discharged from the filter holes of the filter cylinder 4, and finally discharged from the discharge pipe 28 along the curved surface at the top of the cylinder shell 1, realizing the full filtration and extraction of the carrot juice in the carrot residue.

[0049] After the carrot residue in the filter cylinder 4 has been filtered for a period of time, it will accumulate and block the internal filter holes, resulting in the inability to continue the separation and filtration. At this time, the torsion hinge of the bottom cover 14 should be first operated to face the auxiliary plate 24, and the hole 17 should be closed to stop the operation of the equipment. Subsequently, by controlling the telescopic movement of the multi-stage hydraulic cylinder 8, the pressing block one 9 and the pressing block two 10 are driven to move downward in the filter cylinder 4 to squeeze the filtered carrot residue. Under the action of its own gravity and the elastic force of the spring one 12, the pressing block two 10 will contact the carrot residue in the filter cylinder 4 prior to the pressing block one 9, realizing the secondary extrusion and extraction of the residual carrot juice in the residue. Then, the multi-stage hydraulic cylinder 8 continues to descend, pushing the pressing block one 9 to apply pressure to the pressing block two 10, compressing the spring one 12, and finally engaging with the inner wall of the pressing block two 10.

[0050] The U-shaped rod 26 fixed to the pressing block one 9 will also descend synchronously along the path of the auxiliary plate 24, and drive the teeth 27 at the bottom end to engage with the teeth of the adjusting wheel 23, so that the anti-disengagement pipe 22 pulls the bottom cover 14 to rotate and open in the horizontal direction of the adjusting wheel 23 through the telescopic rotating block 19 and the spring two 21, so that the fully pressed carrot residue in the filter cylinder 4 is completely discharged from the filter cylinder 4.
