Description

Technical Field

[0001] This utility model relates to the field of amino acid production technology, specifically a sealed centrifuge for amino acid production. Background Technology

[0002] In amino acid production, sealed centrifuges play a key role in solid-liquid separation, quality control, and process stability by combining mechanical separation with sealing protection. Specifically, during operation, they use centrifugal force to rapidly separate solid particles (such as cells and precipitates) from the liquid phase in amino acid fermentation broth or reaction mixture, providing the basic conditions for subsequent purification or drying processes. This process can replace traditional filtration methods, significantly improving separation efficiency and quality.

[0003] Currently, existing sealed centrifuges for amino acid production mainly utilize the centrifugal force generated by the rotation of the drum to separate the solid and liquid components of the amino acid fermentation broth. However, considering that most amino acid fermentation broths have high viscosity, the high viscosity of the fermentation broth often increases the resistance of the drum rotation during the actual separation process. This leads to a decrease in the separation and settling speed and the separation efficiency during equipment operation, and also increases the overall wear and tear on the equipment. Therefore, a sealed centrifuge for amino acid production is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a sealed centrifuge for amino acid production, in order to solve the problem mentioned in the background art that, when using existing sealed centrifuges for amino acid production, the high adhesion of amino acid fermentation broth often increases the resistance of the drum rotation, resulting in a slowdown in separation and sedimentation speed and a decrease in separation efficiency during equipment operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A sealed centrifuge for amino acid production includes a flat base. A centrifuge chamber is fixedly connected to the top center of the flat base. A sealing cover is fitted onto the top of the centrifuge chamber. A pretreatment sleeve is located on the right side of the top of the sealing cover. A ceramic conical disc is located in the center of the interior of the pretreatment sleeve. An upper conical ring is fitted onto the outer side of the tip of the ceramic conical disc. An inner retainer threadedly connected to the pretreatment sleeve is fixedly connected to the outer side of the upper conical ring. An annular temperature controller is fitted onto the lower outer side of the pretreatment sleeve. An electric heating needle is electrically connected to the top of the annular temperature controller. A support block is fixedly connected to the lower outer side of the ceramic conical disc. A lower conical ring is fixedly connected to the lower interior of the pretreatment sleeve. A power terminal is electrically connected to the left side of the annular temperature controller.

[0007] Preferably, a drive chamber is fixedly connected to the bottom center of the flat plate base, a drive motor is fixedly installed at the bottom center of the drive chamber, and a liquid outlet bend is provided on the bottom left side of the flat plate base, which communicates with the inside of the centrifuge chamber. The liquid outlet bend has an "L" shaped structure.

[0008] Preferably, a hinge joint is fixedly connected to the right side of the sealing cover, and an electric actuator is hinged to the top right side of the flat plate base, with the movable end of the electric actuator and the hinge joint rotatably connected together.

[0009] Preferably, a separation drum body is rotatably connected to the inner side of the centrifuge casing, the output end of the drive motor extends to the inner side of the centrifuge casing and is fixedly connected to the separation drum body, and a feed pipe is provided at the bottom of the pretreatment sleeve, the feed pipe extending through the sealing cover to the inner side of the separation drum body.

[0010] Preferably, the support block has a ring-shaped structure, and several support blocks are arranged in a ring array along the center point of the ceramic conical disk. Several support blocks are fixedly connected to the pretreatment sleeve, and the electric heating needle penetrates the outer wall of the pretreatment sleeve and the interior of the support block to extend to the inner side of the ceramic conical disk.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, the inner sleeve, upper conical ring, ceramic conical disc, annular temperature controller, power terminal, electric heating needle, and support block are designed to facilitate the preheating treatment of the high-viscosity amino acid fermentation broth in the sealed centrifuge for amino acid production. This is achieved through the connection of the sealed top cover and pretreatment sleeve, utilizing the preheating structure composed of the inner sleeve, upper conical ring, ceramic conical disc, annular temperature controller, power terminal, electric heating needle, and support block. This reduces the viscosity of the amino acid fermentation broth, preventing slowed separation and sedimentation rates and decreased separation efficiency due to high viscosity, and reducing overall equipment wear and tear.

A liquid outlet bend 16, communicating with the inside of the centrifuge chamber 2, is provided on the bottom left side of the flat plate base 1. The liquid outlet bend 16 has an "L"-shaped structure, which facilitates the discharge of the separated fermentation broth. A hinge joint 14 is fixedly connected to the right side of the sealing cover 3, and an electric actuator 15 is hinged to the top right side of the flat plate base 1. The movable end of the electric actuator 15 is rotatably connected to the hinge joint 14. The electric actuator 15... The hinge joint 14 and the sealing cover 3 are connected together, which facilitates the operation of the electric push rod 15 to drive the device and realize the automatic opening and closing of the sealing cover 3. The centrifuge box 2 is rotatably connected to the separation drum body 13. The output end of the drive motor 18 extends to the inside of the centrifuge box 2 and is fixedly connected to the separation drum body 13. The bottom of the pretreatment sleeve 4 is provided with a feed pipe 12, which passes through the sealing cover 3 and extends to the inside of the separation drum body 13. This structure facilitates the direct feeding of the heated amino acid fermentation broth into the separation drum body 13.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the support block 11 has a ring-shaped structure. Several support blocks 11 are arranged in a ring array along the center point of the ceramic conical disk 7. Several support blocks 11 are fixedly connected to the pretreatment sleeve 4.
