Description

Technical Field

[0001] This utility model belongs to the field of antioxidant production, and specifically relates to a solid antioxidant separation device. Background Technology

[0002] Antioxidant separation units are specialized equipment used to separate and purify antioxidants (such as hindered phenols, phosphites, and thioesters) from reaction mixtures, solutions, or crude products. Their core function is to remove impurities (such as unreacted raw materials, byproducts, and solvents) through physical or chemical methods to obtain high-purity antioxidant products. Because antioxidants are diverse (solid and liquid) and vary greatly in properties (solubility, boiling point, stability, etc.), separation units must be custom-designed according to specific types and production processes.

[0003] In existing technologies, traditional separation devices often suffer from material adhesion to the tank walls, leading to reduced effective separation space and decreased separation accuracy. Furthermore, when using centrifugal force to separate solid antioxidants, traditional devices frequently experience uneven separation due to frame instability, resulting in material residue clogging the device. Therefore, this invention proposes a solid antioxidant separation device to address these problems in existing technologies. Utility Model Content

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Please see Figures 1-6 This utility model provides an embodiment: a solid antioxidant separation device, including a separation tank 2, a separation frame 5, a cleaning brush 13, a barrier net 16, and a limiting ring plate 18. A tank cover 3 is installed at the upper end of the separation tank 2, and a hopper 4 is installed at the lower end. A support bracket 1 is fitted onto the outer wall of the separation tank 2. A first ring frame 7 and a second ring frame 8 are respectively fixed to the inner walls of the upper and lower ends of the separation tank 2. The separation frame 5 is rotatably installed between the first ring frame 7 and the second ring frame 8. The upper and lower ends of the separation frame 5 are respectively fixed... The separation frame 5 is connected to a limiting ring plate 18 and a fourth ring frame 14. The four sets of hollow grooves on the outer wall of the separation frame 5 are all fixed with a barrier net 16. The outer wall of the separation frame 5 is fixed with four sets of cleaning brushes 13 that are equidistant from each other around the outer wall of the separation frame 5. The upper end of the limiting ring plate 18 is fixed with a gear ring 12. The upper edge of the tank cover 3 is equipped with a drive motor 20. The output end of the drive motor 20 passes through the tank cover 3 and is fixed with a transmission gear 19. The lower inner wall of the hopper 4 is fixed with a third ring frame 11. The lower end of the separation frame 5 is fixed with a discharge pipe 17.

[0027] The cleaning brush 13, which rotates with the separation frame 5, can clean the tank wall in real time and maintain stable separation efficiency. The separation frame 5, through the double limiting of the limiting ring plate 18 and the fourth ring frame 14, can avoid eccentricity or shaking during rotation. The interconnected second through hole 10, third through hole 15 and discharge pipe 17 form two sets of discharge paths to ensure the smooth discharge of coarse and fine materials and avoid material retention and blockage in the device.

[0028] Please see Figures 3-5In this embodiment, four sets of second through holes 10 are equidistantly distributed around the inner wall of the second ring frame 8 at both ends of the upper and lower edges. Four sets of third through holes 15 are equidistantly distributed around the inner wall of the fourth ring frame 14 at both ends of the upper and lower edges. The first ring frame 7 and the second ring frame 8 allow the separation frame 5 to be rotatably installed at the center of the inner wall of the separation tank 2. The second through holes 10 and the third through holes 15 are interconnected. The lower end of the limiting ring plate 18 is in contact with the upper end of the first ring frame 7, and the upper end of the fourth ring frame 14 is in contact with the lower end of the second ring frame 8. The limiting ring plate 18 can separate the gear ring 12 on the upper inner wall of the separation tank 2 to prevent the antioxidant after separation from being adsorbed onto the gear ring 12 and affecting the normal operation of the gear ring 12.

[0029] Please see Figure 6 In this embodiment, a feed funnel 6 is installed through the center of the can lid 3. The feed funnel 6 consists of two funnels that are symmetrically arranged vertically. The feed funnel 6 can collect and stably transport the antioxidant raw materials into the separation frame 5.

[0030] Please see Figure 5-Figure 5 In this embodiment, the gear ring 12 meshes with the transmission gear 19, and the top of the cleaning brush 13 is in contact with the inner wall of the separation tank 2. The meshing gear ring 12 and the transmission gear 19 can drive the drive motor 20 to rotate the separation frame 5 at high speed, so as to separate the antioxidant raw materials inside by centrifugal force. The inner wall diameter of the gear ring 12 is the same as the inner wall diameter of the separation frame 5 and they are interconnected. The outer wall of the feed funnel 6 is in contact with the inner wall of the separation frame 5. The interconnected inner walls of the gear ring 12 and the separation frame 5 can allow the feed funnel 6 to enter the separation frame 5. The lower end of the discharge pipe 17 passes through the central inner wall of the third ring frame 11 and is exposed at the lower end of the hopper 4. The upper and lower ends of the third ring frame 11 are provided with four sets of first through holes 9 that are equidistantly distributed around the inner wall of the third ring frame 11. The discharge pipe 17 can discharge the antioxidant raw material residue in the bottom-closed separation frame 5 to the outside, and the discharge and closing of the discharge pipe 17 can be controlled by the electric valve inside.

[0031] First, the solid antioxidant material is fed into the separation frame 5 through the feed funnel 6 in the center of the tank cover 3. Since the outer wall of the feed funnel 6 is in contact with the inner wall of the separation frame 5, the solid antioxidant material can be prevented from leaking out from the gap between the separation frame 5 and the separation tank 2, so that the solid antioxidant material can directly enter the separation frame 5.

[0032] Next, the drive motor 20 is started. The drive motor 20 drives the separation frame 5 to rotate stably at high speed between the first ring frame 7 and the second ring frame 8 through the meshing transmission gear 19 and gear ring 12. At the same time, under the centrifugal force generated during rotation, the barrier net 16 in the hollow groove of the separation frame 5 can pass through the barrier net 16 and enter the gap between the separation tank 2 and the separation frame 5, while the larger solid antioxidant particles are blocked inside the separation frame 5 to achieve "coarse and fine separation".

[0033] Then, the coarse particles inside the separation frame 5 are discharged directly through the discharge pipe 17 at the lower end, while the fine particles that pass through the barrier net 16 flow into the hopper 4 through the second through hole 10 of the second ring frame 8 and the third through hole 15 of the fourth ring frame 14, and are finally discharged from the fourth ring frame in the hopper 4, thereby realizing the separate collection of materials of different particle sizes.

[0034] When the separation frame 5 rotates, the four sets of cleaning brushes 13 fixed to the outer wall of the separation frame 5 will rotate synchronously with the frame to automatically clean the material attached to the inner wall of the separation tank 2 and avoid residue accumulation.

[0035] Through the above steps, the cleaning brush 13, which rotates with the separation frame 5, can clean the tank wall in real time, maintaining stable separation efficiency. The separation frame 5, through the double limiting of the limiting ring plate 18 and the fourth ring frame 14, can avoid eccentricity or shaking during rotation. The interconnected second through hole 10, third through hole 15 and discharge pipe 17 form two sets of discharge paths, which can ensure the smooth discharge of coarse and fine materials, and avoid material retention and blockage in the device. This solves the problem that the existing separation device has poor separation effect on solid antioxidants and is prone to material blockage.

[0036] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
