Description

Technical Field

[0001] This utility model relates to the technical field of hesperidin extraction production equipment, and in particular to a centrifugal device for hesperidin crystallization and separation. Background Technology

[0002] Hesperidin is an extract from the dried young fruit of Citrus aurantium (a plant in the Rutaceae family), its cultivated varieties, or sweet orange; the fruit of Citrus medica (a plant in the Rutaceae family); the fruit of Citrus reticulata (a plant in the Rutaceae family); the peel of Citrus aurantium (a plant in the Rutaceae family); the mature fruit of Citrus medica (a plant in the Rutaceae family); and the whole herb of Capsella bursa-pastoris (a plant in the Brassicaceae family) with roots.

[0003] In the production of hesperidin, fresh orange peels are first selected as raw materials, washed and chopped, and then the chopped citrus peels are mixed with a solvent (such as ethanol) for extraction. Finally, a centrifuge is used to separate the solid and liquid components to obtain a filtrate containing hesperidin.

[0004] However, the centrifuge has limited separation capacity, and some filtrate will remain in some orange peel residue, wasting a certain amount of hesperidin and reducing the yield of hesperidin crystallization and separation in the subsequent filtrate. Utility Model Content

[0005] In view of the above problems, this utility model provides a centrifugal device for the crystallization and separation of hesperidin, the purpose of which is to reduce the waste of hesperidin and increase the yield of hesperidin crystallization and separation.

[0006] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0007] A centrifugal device for separating hesperidin crystals is provided, comprising: a centrifuge body, a cover plate, a centrifuge drum, and a motor. The centrifuge drum is rotatably disposed within the centrifuge body, the cover plate is used to seal the centrifuge drum, and the output shaft of the motor is drively connected to the centrifuge drum; a support component disposed within the centrifuge body; a lifting assembly disposed on the cover plate, used to drive the support component to move up and down along the direction of gravity, thereby driving the support component into / out of the centrifuge drum; a slider slidably disposed on the support component, capable of sliding along the radial direction of the centrifuge drum; a rotating roller parallel to the central axis of the centrifuge drum, rotatably disposed on the slider; and a telescopic component, the main body of which is fixedly installed on the support component, the piston rod of which is used to push the slider toward the inner wall surface of the centrifuge drum, thereby squeezing the orange peel residue.

[0008] Furthermore, the supporting components include: a mounting plate and a mounting post, with the two mounting plates arranged in parallel and the two mounting plates fixedly connected to both ends of the mounting post.

[0009] Furthermore, the supporting component also includes: several dovetail grooves along the radial direction of the centrifugal drum, with several dovetail grooves opened on the mounting plate, and a slider can be slidably installed in each dovetail groove.

[0010] Furthermore, the device also includes a tension spring, installed in the dovetail groove, with one end of the tension spring connected to the slider and the other end of the tension spring connected to the mounting plate, providing the slider with a tendency to move away from the inner wall of the centrifugal drum.

[0011] Furthermore, the device also includes a swivel ball, the mounting base of which is disposed on the piston rod of the telescopic component, and the ball of which is used to abut against the rotating roller.

[0012] Furthermore, both ends of a rotating roller are rotatably mounted on a slider via bearings.

[0013] Furthermore, the lifting assembly is a screw jack.

[0014] The beneficial effects of this invention are as follows: by using this invention, the rotating roller can squeeze the orange peel residue on the inner wall of the centrifugal drum along the circumferential direction, effectively squeezing out the residual filtrate in the orange peel residue, reducing the waste of hesperidin, effectively improving the crystallization and separation efficiency of hesperidin in the subsequent filtrate, and increasing the yield of hesperidin.

[0017] The components include: 1. Centrifuge body; 11. Cover plate; 12. Centrifuge drum; 13. Motor; 41. Mounting plate; 42. Mounting column; 43. Tension spring; 5. Lifting assembly; 6. Telescopic component; 61. Universal ball; 7. Rotary roller; 8. Slider. Detailed Implementation

[0018] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0019] Reference Figure 1 and Figure 2As shown in the embodiment of this application, a centrifugal device for separating hesperidin crystals is disclosed, comprising: a centrifuge body 1, a cover plate 11, a centrifugal drum 12, and a motor 13. The centrifugal drum 12 is rotatably disposed within the centrifuge body, and the cover plate 11 is used to cover the centrifugal drum 12. The output shaft of the motor 13 is connected to the centrifugal drum 12 via a transmission connection. A carrying component is disposed within the centrifuge body 1. A lifting component 5 is disposed on the cover plate 11 and is used to drive the carrying component to move up and down along the direction of gravity, thereby driving the carrying component to enter / exit the centrifugal drum 12. A slider 8 is slidably disposed on the carrying component and can slide along the radial direction of the centrifugal drum 12. A rotating roller 7 is parallel to the central axis of the centrifugal drum 12 and is rotatably disposed on the slider 8. A telescopic component 6 is fixedly installed on the carrying component, and the piston rod of the telescopic component 6 is used to push the slider 8 toward the inner wall surface of the centrifugal drum 12, thereby squeezing the orange peel residue.

[0020] In practical use, the extract containing orange peel residue is placed into the centrifuge drum 12. The motor 13 is started to drive the centrifuge drum 12 to rotate for a fixed time, completing one centrifugal separation operation of the extract. The motor 13 is then stopped, the lifting component 5 is started, and the carrying component is driven down into the centrifuge drum 12. Then the telescopic component 6 is started, and the piston rod of the telescopic component 6 extends, applying force to the rotating roller 7, causing the slider 8 to slide until the rotating roller 7 squeezes the orange peel residue on the inner wall of the centrifuge drum 12. The motor 13 is then started again to drive the centrifuge drum 12 to rotate slowly, causing the centrifuge drum 12 and the rotating roller 7 to move relative to each other in the circumferential direction. The rotating roller 7 squeezes the orange peel residue on the inner wall of the centrifuge drum 12 in the circumferential direction. Finally, the telescopic component 6 and the lifting component 5 are reset, and the centrifuge body performs the separation operation again. This cycle is repeated many times to finally complete the centrifugal separation of the extract containing orange peel residue.

[0021] By using this invention, the rotating roller 7 can squeeze the orange peel residue on the inner wall of the centrifugal drum 12 in the circumferential direction, effectively squeezing out the residual filtrate in the orange peel residue, reducing the waste of hesperidin, effectively improving the crystallization and separation efficiency of hesperidin in the subsequent filtrate, and increasing the yield of hesperidin.

[0022] It is worth mentioning that the centrifugal drum 12 can be rotatably installed inside the centrifuge body 1 via a turntable bearing, and the output shaft of the centrifugal drum 12 and the motor 13 can be connected by a belt drive. Of course, pulleys for tensioning the drive belt should be installed on the output shaft of the motor 13 and the centrifugal drum 12.

[0023] It is understandable that one side of the cover plate 11 is hinged to the centrifuge body 1 via a hinge shaft.

[0024] Specifically, the supporting components include: mounting plate 41 and mounting post 42. The two mounting plates 41 are arranged in parallel, and the two ends of the mounting post 42 are respectively fixedly connected to the two mounting plates 41. The two ends of the mounting post 42 can be fixedly connected to the two mounting plates 41 by welding.

[0025] Specifically, the supporting component also includes: several dovetail grooves along the radial direction of the centrifugal drum 12, several dovetail grooves are opened on the mounting plate 41, and a slider 8 can be slidably installed in each dovetail groove; by setting the dovetail grooves to guide the slider 8 to slide, the stability of the slider 8 sliding can be effectively improved.

[0026] Preferably, the device further includes a tension spring 43, which is installed in the dovetail groove. One end of the tension spring 43 is connected to the slider 8, and the other end of the tension spring 43 is connected to the mounting plate 41, providing the slider 8 with a tendency to move away from the inner wall of the centrifugal drum 12.

[0027] In practical use, when the piston rod of the telescopic component 6 extends, the slider 8 can slide close to the inner wall of the centrifugal drum 12 and stretch the tension spring 43; when the piston rod of the telescopic component 6 extends, under the force of the tension spring 43 restoring its deformation, the tension spring 43 can pull the slider 8 away from the inner wall of the centrifugal drum 12 and drive the roller 7 to automatically reset.

[0028] In this embodiment, the main body of the telescopic component 6 is fixedly mounted on the mounting column 42. For each rotating roller 7, three telescopic components 6 are arranged in parallel on the main body. The rotating roller 7 is pushed by the three telescopic components 6, thereby improving the stability of the moving roller 7 by the telescopic components 6.

[0029] It is worth mentioning that the telescopic component 6 can be a cylinder. Of course, the maximum stroke of the telescopic rod of the cylinder should be controlled, and a certain gap should be reserved between the outer wall of the roller 7 and the inner wall of the centrifugal drum 12.

[0030] Preferably, the device further includes a universal ball 61, the fixed seat of which is disposed on the piston rod of the telescopic component 6, and the ball of the universal ball 61 is used to abut against the rotating roller 7; by the ball of the universal ball 61 rolling to contact the rotating roller 7, the wear between the rotating roller 7 and the piston rod of the telescopic component 6 can be effectively reduced.

[0031] Specifically, both ends of a rotating roller 7 are rotatably mounted on a slider 8 via bearings; in the specific installation, the two sliders 8 at both ends of a rotating roller 7 are respectively mounted on two mounting plates 41.

[0032] In this embodiment, two rotating rollers 7 are symmetrically arranged on both sides of the mounting column 42.

[0033] Preferably, the lifting assembly 5 is a screw jack. In this embodiment, a plurality of screw jacks are provided on the cover plate 11. One end of the screw of the screw jack passes through the cover plate 11 and is mounted on the mounting plate 41 through a flange. It is worth mentioning that the power of the screw jack can be provided by a servo motor 13 or a stepper motor 13. The specific installation method is well known in the art and will not be described in detail here.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.
