Description

Technical Field

[0001] The utility model relates to the technical field of microcapsules, and particularly relates to an emulsifying and centrifugal separation device for preparing photochromic microcapsules. Background Technique

[0002] Photochromic microcapsules are technical products that encapsulate photochromic materials into tiny particles through special processes. Such microcapsules can change color according to changes in external conditions (such as temperature, light, etc.) and have broad application prospects; such microcapsules can change color according to temperature changes, and their color-changing principle usually involves changes in the molecular structure of temperature-sensitive materials, resulting in changes in the reflection or absorption spectrum; emulsifying centrifugal separation is a separation technique based on the density difference of substances and the action of centrifugal force, and is commonly used for the separation of oil and water in emulsions and the separation of other liquids and solids. The emulsifying centrifugal separation technique uses the high-speed rotational force generated by a centrifuge to separate different components in the emulsion due to density differences. Under the action of centrifugal force, the components with larger density will move towards the edge of the centrifuge to form an aqueous phase layer; while the components with smaller density will gather in the central area to form an oil phase layer. In this way, the originally mixed emulsion is effectively separated into two parts. Thermochromic microcapsules have wide applications in the fields of intelligent materials, biomedicine, textiles, coatings, etc.;

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 efforts shall fall within the protection scope of the present invention. Specific Embodiment 1

[0032] This embodiment is an emulsifying centrifugal separation device for preparing photochromic microcapsules.

[0033] As Figure 1 , Figure 2 and Figure 4 shown, a slot 2 is opened inside the mounting seat 1. A turning handle 3 is rotatably connected to the front side of the mounting seat 1. A gear 4 is fixedly connected to the rear side of the turning handle 3. The gear 4 is meshed with a toothed plate 5. The toothed plate 5 is fixedly installed on the upper side of the lower limit plate 6 and also fixedly installed on the lower side of the upper limit plate 9. Both the lower limit plate 6 and the upper limit plate 9 are arranged inside the slot 2. The lower limit plate 6 is located below the upper limit plate 9. Both the lower limit plate 6 and the upper limit plate 9 are slidably connected to the slot 2. A first threaded rod 7 is threadedly connected to the right side of the lower limit plate 6. The first threaded rod 7 is rotatably connected to an anti-slip seat 8, and the anti-slip seat 8 is snap-fitted with the lower limit plate 6. When the anti-slip seat 8 moves up and down, the anti-slip seat 8 can only move up and down. In addition, the upper limit plate 9 is threadedly connected to a second threaded rod 10. An anti-slip seat 8 is also arranged inside the second threaded rod 10. The second threaded rod 10 is also rotatably connected to the anti-slip seat 8. An operation box 11 is fixedly connected to the upper side of the mounting seat 1.

[0034] As Figure 1 , Figure 3 and Figure 5As shown in the figure, a motor 12 is provided on the upper side of the operation box 11. The output shaft of the motor 12 is fixedly connected to the centrifugal filter cartridge 13. The centrifugal filter cartridge 13 is located inside the operation box 11. The electric telescopic rod 14 is fixedly connected to the upper inner side of the operation box 11. The lower side of the electric telescopic rod 14 is fixedly connected to the water spraying ring 15. The electric telescopic rod 14 is symmetric about the vertical central axis of the mounting base 1. A high-pressure nozzle 16 is provided on the outer side of the water spraying ring 15. The high-pressure nozzles 16 are arranged in an array. A water delivery pipe 17 is provided on the upper side of the water spraying ring 15. The water delivery pipe 17 passes through the upper wall of the operation box 11. A discharge port 18 is provided on the lower side of the operation box 11. A certain distance is reserved between the discharge port 18 and the mounting base 1 to facilitate discharging. Specific Embodiment Two

[0036] This embodiment is to solve the problem of shaking during centrifugation.

[0037] As Figure 1 、 Figure 2 and Figure 4 As shown in the figure, turn the turning handle 3 on the front side of the mounting base 1. Since the turning handle 3 is connected to the lower limit plate 6 and the upper limit plate 9 through the gear 4 and the toothed plate 5, when the turning handle 3 rotates, the lower limit plate 6 and the upper limit plate 9 move in opposite directions. In addition, stoppers are provided on the sides of the lower limit plate 6 and the upper limit plate 9 to prevent the lower limit plate 6 and the upper limit plate 9 from moving too far and disconnecting from the gear 4, thus failing to achieve the purpose of expanding the contact area between the operation box 11 and the ground, and reinstallation also wastes time and reduces ineffective operations.

[0038] As Figure 4 As shown in the figure, when the lower limit plate 6 extends out, turn the first threaded rod 7. Since the first threaded rod 7 is threadedly connected to the lower limit plate 6, the first threaded rod 7 is rotatably connected to the anti-slip seat 8, and the anti-slip seat 8 can only move up and down under the limiting action of the lower limit plate 6. Therefore, by turning the first threaded rod 7, the anti-slip seat 8 on the lower side of the lower limit plate 6 can be brought into contact with the ground, thereby preventing the lower limit plate 6 from shifting due to the vibration generated during centrifugation. In addition, the anti-slip seat 8 on the side of the upper limit plate 9 is rotated in the same way by turning the second threaded rod 10 to bring the corresponding anti-slip seat 8 of the upper limit plate 9 into contact with the ground. When the centrifugation operation is over, turn the first threaded rod 7 and the second threaded rod 10 in the reverse direction to retract the lower limit plate 6 and the upper limit plate 9 into the slot 2 inside the mounting base 1, and then the device can be moved, which is convenient for operation. Specific Embodiment Three

[0040] This embodiment is to solve the problem that the filter holes of the centrifugal filter cartridge 13 are not cleaned thoroughly.

[0041] As Figure 1 and Figure 3As shown in the figure, a feeding pipe is provided on the upper side of the operation box 11. The lower side of the feeding pipe is located above the inside of the centrifugal filter cylinder 13. Materials are added into the centrifugal filter cylinder 13 from the feeding pipe. Then, the motor 12 is started. The motor 12 will drive the centrifugal filter cylinder 13 to rotate together. The rotating centrifugal filter cylinder 13 will perform centrifugal operation on the emulsified materials. Then, the valve on the discharge port 18 is opened, and the materials are discharged from the discharge port 18.

[0042] As Figure 1 and Figure 3 shown, after the centrifugal operation, the electric telescopic rod 14 is started, and the water delivery pipe 17 is externally connected to high-pressure water. Since the water spraying ring 15 is located outside the output shaft of the motor 12, when the centrifugal filter cylinder 13 is rotating, it will not contact the water spraying ring 15, which is convenient for water spraying. The electric telescopic rod 14 will drive the water spraying ring 15 and the water delivery pipe 17 to move up and down together. The high-pressure nozzles 16 on the side of the water spraying ring 15 will spray high-pressure water columns. And the centrifugal filter cylinder 13 is still rotating. Therefore, under the cooperative work of the centrifugal filter cylinder 13 and the electric telescopic rod 14, the impurities on the inner side of the centrifugal filter cylinder 13 and on the filter holes in the centrifugal filter cylinder 13 will be cleaned up, which is convenient for the next use. The sewage will be discharged from the discharge port 18 to the outside of the operation box 11.

The machines, parts, and equipment all adopt conventional models in the prior art. In addition, the circuit connection adopts the conventional connection method in the prior art, which will not be elaborated here.
