Description

Technical Field

[0001] This utility model relates to the field of amino acid processing technology, and in particular to an amino acid purification device. Background Technology

[0002] Amino acids are organic compounds containing a basic amino group and an acidic carboxyl group. They are compounds formed when the hydrogen atom on the carbon atom of a carboxylic acid is replaced by an amino group. When purifying and separating amino acids, precipitation, ion exchange, extraction, adsorption, and crystallization are commonly used methods. Crystallization requires the use of a crystallizer.

[0003] In existing technologies, during the evaporation crystallization process, the evaporation of the amino acid solvent causes the solute concentration near the crystallizer wall to rise rapidly, exceeding its solubility limit. This leads to the amino acid crystallizing on the wall, making the crystals tightly adhered to the wall. This not only makes them difficult to remove but also results in incomplete crystal collection, thus reducing their practicality. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that, during the evaporation and crystallization process of amino acid solvent, the solute concentration near the crystallizer wall rises rapidly, exceeding its solubility limit, causing amino acids to crystallize on the wall. The crystals adhere tightly to the wall, making them difficult to remove and resulting in incomplete crystal collection and low practicality. Therefore, this invention proposes an amino acid purification device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an amino acid purification device, comprising a cylinder, a cover plate fixedly connected to the top of the cylinder, a support plate fixedly connected to the bottom of the cylinder, a rotary motor fixedly connected to the inner surface of the support plate, a lead screw fixedly connected to the output end of the rotary motor, a lifting plate threadedly connected to the outer surface of the lead screw, connecting pipes symmetrically and movably passing through the top of the cover plate, a scraper ring fixedly connected between the bottoms of the two connecting pipes, a plurality of oblique holes evenly formed on the inner surface of the scraper ring, a water tank fixedly connected to the rear surface of the support plate, a water pump fixedly connected to the top of the water tank, and a flexible hose fixedly connected to the output end of the water pump.

[0006] Preferably, the tops of both connecting pipes are fixedly connected to the bottom of the lifting plate, the bottom of one of the connecting pipes is connected to the top of the scraper ring, and the top of the connecting pipe is connected to the bottom of the hose.

[0007] Preferably, the outer surface of the scraper ring matches the inner surface of the cylinder, and a drive motor is fixedly connected to the top of the cover plate, with the output end of the drive motor movably penetrating through the top of the cover plate.

[0009] Preferably, the top of the lifting plate is symmetrically and movably connected with guide rods, and both ends of the two guide rods are fixedly connected to the inner walls of both sides of the support plate.

[0010] Preferably, the top of the lifting plate is provided with multiple positioning holes, and the top of the cover plate is fixedly connected with multiple threaded rods, the outer surfaces of the multiple threaded rods respectively cooperating with the positions of the multiple positioning holes.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, the rotary motor is started, and under the action of the lead screw and guide rod, the lifting plate and connecting pipe move downward, driving the scraper ring to move downward along the inside of the cylinder to scrape off the crystals adhering to the inner wall.

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1, such as Figures 1-4 As shown, this utility model provides an amino acid purification device, including a cylinder 1. A cover plate 2 is fixedly connected to the top of the cylinder 1, and a support plate 14 is fixedly connected to the bottom of the cylinder 1. A rotary motor 11 is fixedly connected to the inner surface of the support plate 14, and a lead screw 12 is fixedly connected to the output end of the rotary motor 11. A lifting plate 6 is threadedly connected to the outer surface of the lead screw 12. A connecting pipe 5 is symmetrically and movably inserted through the top of the cover plate 2. A scraper ring 15 is fixedly connected between the bottoms of the two connecting pipes 5. A plurality of oblique holes 18 are evenly opened on the inner surface of the scraper ring 15. A water tank 8 is fixedly connected to the rear surface of the support plate 14, and a water pump 9 is fixedly connected to the top of the water tank 8. The output end of the water pump 9 is fixedly connected to... A flexible hose 10 is connected to the top of two connecting pipes 5, and the top of each connecting pipe 5 is fixedly connected to the bottom of the lifting plate 6. The bottom of one of the connecting pipes 5 is connected to the top of the scraper ring 15, and the top of the connecting pipe 5 is connected to the bottom of the flexible hose 10. The outer surface of the scraper ring 15 is matched with the inner surface of the cylinder 1. A drive motor 4 is fixedly connected to the top of the cover plate 2. The output end of the drive motor 4 is movably connected to the top of the cover plate 2. A stirring rod 17 is fixedly connected to the output end of the drive motor 4. Multiple stirring blades 16 are fixedly connected to the outer surface of the stirring rod 17. Guide rods 13 are symmetrically movably connected to the top of the lifting plate 6. Both ends of the two guide rods 13 are fixedly connected to the inner walls of both sides of the support plate 14.

[0022] The overall effect of Example 1 is as follows: During use, after the pretreated amino acid solution is added to the inside of the cylinder 1, it is heated by the internal heating coil of the cylinder 1 to evaporate the amino acid solution. Under the action of the drive motor 4, the stirring rod 17 and stirring blade 16 are rotated to make the solute molecules evenly distributed, accelerating the formation of crystal nuclei and crystal growth. After the treatment is completed, the discharged material can be collected through the discharge port. When there are crystals adhering to the inner wall of the cylinder 1, the rotary motor 11 can be started to drive the lead screw 12 to rotate. Under the action of the guide rod 13, the lifting plate 6 is moved downward, so that the two... The connecting pipe 5 moves downward along the cover plate 2, causing the scraper ring 15 to move downward along the inside of the cylinder 1, scraping off the crystals adhering to the inner wall. At the same time, as the scraper ring 15 moves downward, the water pump 9 continuously draws out the cleaning fluid from the water tank 8, and then delivers it to the inside of the scraper ring 15 through the hose 10 and the connecting pipe 5. The cleaning fluid is then evenly sprayed onto the inner wall of the cylinder 1 through the oblique hole 18, assisting the scraper ring 15 in removing residual crystals, avoiding crystal residue on the cylinder 1, and providing good conditions for the subsequent crystallization treatment of amino acid solution, thus improving the processing efficiency. The input end of the water pump 9 is connected to the water tank 8 through a water supply pipe.

[0023] Example 2, as Figures 1-4 As shown, the top of the lifting plate 6 is provided with multiple positioning holes 7, and the top of the cover plate 2 is fixedly connected with multiple threaded rods 3, the outer surfaces of the multiple threaded rods 3 respectively cooperating with the positions of the multiple positioning holes 7.

[0024] The effect achieved by the entire embodiment 2 is that when it is necessary to replace the internal parts of the cylinder 1, the rotary motor 11 can be started to drive the lifting plate 6 to move downward, so that the threaded rod 3 on the cover plate 2 is inserted into the corresponding positioning hole 7 of the lifting plate 6, and then fixed by the external nut. Therefore, when the rotary motor 11 drives the lifting plate 6 to move upward, it can drive the cover plate 2 to move downward, so that the cover plate 2 is separated from the cylinder 1, which facilitates the maintenance of the device.

[0025] Working principle: During use, the pretreated amino acid solution is added to the inside of cylinder 1. The solution is then heated by the internal heating coil to evaporate. Driven by motor 4, the stirring rod 17 and stirring blades 16 rotate, ensuring uniform distribution of solute molecules and accelerating crystal nucleation and growth. After processing, the solution is collected through the discharge port. When crystals adhere to the inner wall of cylinder 1, the rotary motor 11 is activated, driving the lead screw 12 to rotate. Under the action of guide rod 13, the lifting plate 6 moves downwards, causing the two connecting pipes 5 to move downwards along the cover plate 2. This causes the scraper ring 15 to move downwards along the inside of cylinder 1, scraping away the crystals adhering to the inner wall. Simultaneously, as the scraper ring 15 moves downwards... During operation, the water pump 9 continuously draws out the cleaning fluid from the water tank 8 and then delivers it to the inside of the scraper ring 15 through the hose 10 and connecting pipe 5. The cleaning fluid is then evenly sprayed onto the inner wall of the cylinder 1 through the oblique hole 18, assisting the scraper ring 15 in removing residual crystals and preventing crystal residue on the cylinder 1. This also provides good conditions for the subsequent crystallization treatment of the amino acid solution. When it is necessary to replace the internal parts of the cylinder 1, the rotary motor 11 can be started to drive the lifting plate 6 to move downward, so that the threaded rod 3 on the cover plate 2 is inserted into the corresponding positioning hole 7 of the lifting plate 6 and then fixed by the external nut. Therefore, when the rotary motor 11 drives the lifting plate 6 to move upward, it can drive the cover plate 2 to move downward, so that the cover plate 2 is separated from the cylinder 1, which facilitates the maintenance of the device.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
