[0002] A centrifuge is a machine that uses centrifugal force to separate the components of a liquid and solid particles or a mixture of liquids. It is mainly used to separate solid particles from liquids in a suspension; or to separate two immiscible liquids with different densities in an emulsion; it can also be used to remove liquid from wet solids. A search revealed that patent application number 202222758953.7 discloses a centrifuge for amino acid production, including a mounting frame. Fixing blocks are installed on the upper and lower sides of the left inner wall of the mounting frame, and a separation chamber is installed on the right side of the fixing blocks. A drive motor is installed in the middle of the top of the separation chamber.

[0003] However, in actual use, the applicant found that after centrifuging the mixed solution through the centrifuge tube, the heavy liquid and impurities in the solution would remain inside the centrifuge tube. Moreover, the centrifuge tube has a certain height, making it inconvenient for personnel to export the heavy liquid inside the centrifuge tube or to clean out the impurities inside the centrifuge tube. In view of this, we propose a centrifuge for amino acid production. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0020] Please see Figure 1-3 As shown, this utility model provides a technical solution:

[0021] A centrifuge for amino acid production includes a cylinder 1. An annular collection box 6 is fixedly connected to the inner wall of the cylinder 1. A drain pipe 5 is fixedly connected to the bottom of the annular collection box 6. The lower end of the drain pipe 5 extends to the outside of the cylinder 1 and is fitted with a first hand valve 4. A support plate 10 is fixedly connected to the inner wall of the cylinder 1 below the annular collection box 6. A centrifuge cylinder 8 is rotatably connected to the middle of the support plate 10 via a bearing. A motor 2 is fixedly mounted at the bottom of the support plate 10 on one side of the centrifuge cylinder 8. The rotating end of the motor 2 movably passes through the support plate 10. A gear 3 is fitted and fixed to the centrifuge cylinder 8, and a gear ring 9 is fitted and fixed to the centrifuge cylinder 8. The gear ring 9 meshes with the gear 3. A liquid guide eave 81 is provided on the upper part of the centrifuge cylinder 8. The outer edge of the liquid guide eave 81 is located on the upper part of the annular liquid collection box 6. The liquid guide eave 81 can smoothly guide the mixed solution into the centrifuge cylinder 8, and can also guide the light liquid in the mixed solution to the annular liquid collection box 6 for collection during centrifugation, and can block the heavy liquid, so that the heavy liquid remains in the centrifuge cylinder 8. An operation window 15 is opened on the side wall of the lower part of the cylinder 1. The inner side of the cylinder 1 A shaft 14 is fixedly connected to the top of the centrifuge. The lower end of the shaft 14 extends into the centrifuge cylinder 8 after passing through the through hole in the middle of the liquid guide 81. A liquid filling hole is opened on the top of the cylinder 1 on one side of the shaft 14. A control switch 7 is fixedly installed on the outer wall of the cylinder 1 above the operation window 15. The control switch 7 is electrically connected to an external power supply through a wire. The motor 2 is electrically connected to the control switch 7 through a wire. During the amino acid production process, the mixed solution can be poured into the centrifuge cylinder 8 through the liquid filling hole, and the liquid filling hole can be blocked with a sealing cap. Then, the centrifuge cylinder 8 can be driven by the control switch 7. When motor 2 rotates, it drives gear 3 to rotate, which in turn drives gear ring 9 to rotate together with centrifuge cylinder 8, separating the mixed solution in centrifuge cylinder 8. At this time, the heavy liquid in the solution moves away from shaft 14 and remains in centrifuge cylinder 8 due to the obstruction of liquid guide 81. The light liquid in the solution can move upward along shaft 14 and can be discharged to annular collection box 6 through liquid guide 81 for collection. The light liquid collected in annular collection box 6 can be discharged through drain pipe 5 by opening the first hand valve 4.

[0022] A bottom cover 11 is threadedly connected to the lower part of the centrifuge cylinder 8. A filter screen 16 is fixedly connected inside the bottom cover 11. A drain branch pipe 111 is provided at the bottom of the bottom cover 11, and a second hand valve 12 is sleeved and fixed on the drain branch pipe 111. A circular through hole is opened at the bottom of the cylinder 1 below the bottom cover 11. Anti-slip teeth 112 are evenly arranged on the outer wall of the bottom cover 11 to increase the friction between the personnel's hands and the bottom cover 11, making it easier for the personnel to unscrew the bottom cover 11 from the bottom of the centrifuge cylinder 8. An internal thread is opened on the inner side wall of the bottom cover 11, and the internal thread is engaged with the external thread on the lower outer wall of the centrifuge cylinder 8. After centrifugation by the centrifuge cylinder 8, the heavy liquid and impurities will remain in the lower part of the centrifuge cylinder 8. The heavy liquid can be filtered through the filter screen 16 and discharged through the drain branch pipe 111. The impurities filtered by the filter screen 16 can be cleaned by manually unscrewing the bottom cover 11 from the bottom of the centrifuge cylinder 8. The operation is convenient. The bottom of the cylinder 1 is provided with support legs 13 arranged in a ring array. After centrifugation, the heavy liquid in the centrifuge cylinder 8 can be discharged through the drain branch pipe 111 by opening the second hand valve 12. The impurities in the solution can be filtered through the filter screen 16. After the heavy liquid is discharged, the bottom cover 11 can be unscrewed from the bottom of the centrifuge cylinder 8 from the shaft 14. The entire bottom cover 11 can be removed from the shaft 14 to clean the impurities filtered by the filter screen 16.

[0023] Working Principle: During amino acid production, the mixed solution is poured into the centrifuge cylinder 8 through the inlet hole, which is then sealed with a cap. The motor 2 is then driven by the control switch 7. The motor 2 rotates, which in turn drives the gear 3. The gear 3, in turn, drives the gear ring 9, along with the centrifuge cylinder 8, to rotate, separating the mixed solution within the centrifuge cylinder 8. The heavier liquid in the solution moves away from the shaft 14 and remains in the centrifuge cylinder 8 due to the obstruction of the guide vane 81. The lighter liquid in the solution moves upwards along the shaft 14. The liquid can be discharged through the guide eaves 81 to the annular collection box 6 for collection. The light liquid collected in the annular collection box 6 can be discharged through the drain pipe 5 by opening the first hand valve 4. After centrifugation, the heavy liquid in the centrifuge cylinder 8 can be discharged through the drain branch pipe 111 by opening the second hand valve 12. The impurities in the solution can be filtered through the filter screen 16. After the heavy liquid is discharged, the bottom cover 11 can be unscrewed from the bottom of the centrifuge cylinder 8 from the shaft 14. The entire bottom cover 11 can be removed from the shaft 14 to clean the impurities filtered out by the filter screen 16.
