[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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 efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 to 5 , the present invention provides a centrifuge for processing 2-hydroxy-6-naphthoic acid, including an outer cylinder 1 and a centrifugal inner cylinder 7 rotatably connected inside the outer cylinder 1. The centrifugal inner cylinder 7 is provided with a plurality of centrifugal holes. When the centrifugal inner cylinder 7 rotates at a high speed, the liquid in the material is thrown out into the outer cylinder 1 and then discharged from the drain port 12 at the bottom of the outer cylinder 1. The top of the outer cylinder 1 is connected with a rotatable top cover 2. The outer cylinder 1 is connected with a cleaning mechanism for cleaning the centrifugal inner cylinder 7. The cleaning mechanism includes two brush plates 10, brush bristles 11, two L-shaped pressing plates 13, and a plurality of guide cylinders 9. The brush bristles 11 are arranged on the inner side of the brush plate 10. The L-shaped pressing plate 13 is connected to the top of the brush plate 10. The guide cylinder 9 is used to guide the brush plate 10. The L-shaped pressing plate 13 matches the connecting plate 8 connected to the inner side of the top cover 2. The brush plate 10 is connected with a driving mechanism for driving the two brush plates 10 to approach or move away from each other.

[0023] When cleaning the centrifugal inner cylinder 7, the first motor 5 can drive the stud 19 to rotate, so that the two arc-shaped plates 18 approach each other, synchronously driving the two brush plates 10 to approach each other, so that the brush bristles 11 press on the centrifugal inner cylinder 7. At this time, the L-shaped pressing plate 13 and the connecting plate 8 are in a separated state. The second motor 6 drives the centrifugal inner cylinder 7 to rotate, and together with the use of the brush bristles 11, the centrifugal holes of the centrifugal inner cylinder 7 can be cleaned, facilitating subsequent centrifugation operations.

[0024] The cleaning mechanism further includes a plurality of guide posts 14. One end of the guide post 14 is connected to the brush plate 10, and the other end is slidably connected inside the guide cylinder 9. The end of the guide cylinder 9 is fixed to the inner wall of the outer cylinder 1. When the brush plate 10 moves, the end of the guide post 14 slides inside the guide cylinder 9, playing a good guiding role for the brush plate 10 and making the movement of the brush plate 10 stable.

[0025] The driving mechanism includes a motor base 4, a first motor 5, a connecting seat 17, two arc-shaped plates 18, and a stud 19. The motor base 4 is connected to the outer side of the outer cylinder 1, the first motor 5 is connected to the motor base 4, and the power output end of the first motor 5 is connected to the stud 19. The stud 19 is used to drive the two arc-shaped plates 18 to approach or move away from each other. The connecting seat 17 is connected inside the outer cylinder 1, the end of the stud 19 is rotatably connected to the connecting seat 17, and the end of the arc-shaped plate 18 is fixedly connected to the brush plate 10. The first motor 5 can drive the stud 19 to rotate, causing the two arc-shaped plates 18 to approach or move away from each other, and further causing the two brush plates 10 to approach or move away from each other. During the material processing, the two brush plates 10 are in a state of moving away from each other, that is, the bristles 11 are separated from the centrifugal inner cylinder 7, while the end of the L-shaped pressing plate 13 presses against the connecting plate 8 to position and fix the top cover 2, eliminating the need for other locking mechanisms to limit the top cover 2, making the operation simple and convenient. When the centrifugal inner cylinder 7 needs to be cleaned, the two brush plates 10 are in a state of approaching each other, causing the bristles 11 to press against the centrifugal inner cylinder 7. At this time, the L-shaped pressing plate 13 is separated from the connecting plate 8, and the top cover 2 is opened. Workers can use a high-pressure water gun (which is an existing technology) to flush the inner wall of the centrifugal inner cylinder 7. The second motor 6 drives the centrifugal inner cylinder 7 to rotate slowly. In cooperation with the use of the bristles 11, the centrifugal holes can be cleaned and dredged, facilitating subsequent centrifugal operations.

[0026] The stud 19 passes through the ends of the two arc-shaped plates 18, and the stud 19 is threadedly connected to the arc-shaped plates 18. The internal thread directions of the two arc-shaped plates 18 are opposite.

[0027] The top cover 2 is connected to the outer cylinder 1 through a hinge, and a handle 3 is connected to the top of the top cover 2. It is convenient to open or close the top cover 2 by holding the handle 3.

[0028] The second motor 6 is connected to the bottom of the outer cylinder 1, and the power end of the second motor 6 is connected to the centrifugal inner cylinder 7.

[0029] A pressing groove 15 is provided on the side of the connecting plate 8, a slope 16 is provided in the pressing groove 15, and the pressing groove 15 matches the end of the L-shaped pressing plate 13. When the end of the L-shaped pressing plate 13 is connected to the pressing groove 15, the L-shaped pressing plate 13 presses against the slope 16, applying a downward pressure to the connecting plate 8, causing the top cover 2 to press tightly against the outer cylinder 1 and improving the stability of their connection.

[0030] Working principle: When performing centrifugation operations, hold the handle 3 to open the top cover 2, place the material into the centrifugal inner cylinder 7, and then close the top cover 2. The first motor 5 drives the stud 19 to rotate, causing the two brush plates 10 to move away from each other, that is, the bristles 11 move away from the centrifugal inner cylinder 7, while the end of the L-shaped pressing plate 13 presses tightly against the connecting plate 8, thereby achieving the locking of the top cover 2 and improving the stability of the connection between the top cover 2 and the outer cylinder 1. The second motor 6 drives the centrifugal inner cylinder 7 to rotate at high speed, and the liquid in the material is thrown out and discharged from the sewage outlet 12. When the centrifugation operation is completed, the first motor 5 drives the two brush plates 10 to move closer to each other, causing the L-shaped pressing plate 13 to separate from the connecting plate 8 and opening the top cover 2 to facilitate the removal of the material. When the centrifugal inner cylinder 7 needs to be cleaned, the first motor 5 drives the stud 19 to rotate, causing the two arc plates 18 to move closer to each other, synchronously driving the two brush plates 10 to move closer to each other, so that the bristles 11 press against the centrifugal inner cylinder 7. Then, in cooperation with the rotation of the centrifugal inner cylinder 7, the centrifugal holes of the centrifugal inner cylinder 7 can be cleaned to facilitate subsequent centrifugation operations.

[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
