Description

Technical Field

[0001] This utility model belongs to the field of amino acid fermentation broth treatment technology, specifically, it relates to a disc separator. Background Technology

[0002] The treatment of amino acid fermentation broth usually involves a multi-step separation and purification process, and disc separators are often used for solid-liquid separation or liquid-liquid separation in this process, especially in removing bacterial cells, cell debris or impurities.

[0003] Before separation, amino acid fermentation broth needs to undergo pretreatment, which includes: inactivating enzymes in the fermentation broth by heating or adjusting pH to prevent degradation of the target product (amino acids); and adding flocculants (such as chitosan, aluminum sulfate, etc.) to promote the aggregation of cell debris, proteins and other impurities, which facilitates subsequent separation.

[0004] A search revealed that existing disc separators only have the ability to separate solids and liquids. Before processing amino acid fermentation broth, pretreatment of the broth is required, making the processing steps cumbersome and preventing continuous pretreatment, separation, and purification, which affects processing efficiency.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

[0006] To solve the technical problem of pre-processing of amino acid fermentation broth before separation, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A disc-type separator includes a separator body with a feed pipe and a discharge pipe fixedly connected to the upper end of the separator body; and a pretreatment component disposed between the separator body and the feed pipe. The pretreatment component is used for pretreatment of amino acid fermentation broth. The pretreatment component includes a mounting shell, a mixing pipe, and a drive motor. The mounting shells are symmetrically arranged. A support column is fixedly connected to the separator body. Each mounting shell and the drive motor are fixedly connected to the support column. The output end of the drive motor is connected to the components inside the mounting shell and the mixing pipe. The mixing pipe is fixedly connected to the feed pipe.

[0008] In a preferred embodiment of the present invention, the output end of the drive motor is fixedly connected to a first gear, the first gear is symmetrically meshed with a second gear, the second gear is rotatably connected to a connecting block, and the connecting block is connected to the mounting shell by fasteners.

[0009] In a preferred embodiment of this utility model, the second gear is connected to a component block by fasteners, and the component block is in close contact with and rotatably connected to the inner wall of the mounting shell.

[0010] In a preferred embodiment of this utility model, a sealing gasket is installed between each mounting shell and the connecting block, a heating wire is embedded in the inner wall of each mounting shell and is electrically connected to a power source, a connecting end is fixedly connected to the upper end of each mounting shell, a conveying pipe is fixedly connected to the bottom of each mounting shell, and each conveying pipe is fixedly connected to the mixing pipe.

[0011] In a preferred embodiment of the present invention, a first bevel gear is fixedly connected to the first gear, the first bevel gear meshes with a second bevel gear, the second bevel gear is rotatably connected to the mixing tube, and a stirring block is fixedly connected to the bottom of the second bevel gear, and each stirring block is in close contact with the inner wall of the mixing tube.

[0012] In a preferred embodiment of the present invention, a movable block is fixedly connected to the bottom of the stirring block, the movable block is rotatably connected to the inner wall of the mixing tube, a fixed block is abutted against the bottom of the movable block, and the fixed block is fixedly connected to the mixing tube.

[0013] In a preferred embodiment of this utility model, both the movable block and the fixed block are provided with through holes, and the movable block and the fixed block have the same overall structure.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. This disc-type separator, through the arrangement of the separator body and the pretreatment components, achieves the continuous realization of the pretreatment and separation steps of the amino acid fermentation broth before processing, thereby reducing processing steps and improving processing efficiency.

[0016] 2. In this disc-type separator, the heating wire inside the housing is energized and heated after the device is in operation to heat the amino acid fermentation broth flowing through the housing, thereby deactivating the enzymes in the amino acid fermentation broth and preventing the target substance from being deactivated. A certain amount of amino acid fermentation broth and treatment agent are sent into the mixing tube through the conveying pipe.

[0017] 3. This disc-type separator separates the connecting block from the mounting shell using fasteners. After separation, the mounting shell and component blocks are manually cleaned to prevent mixing with the amino acid fermentation broth of the next batch, which would affect the quality of subsequent batches of amino acid fermentation broth. The component blocks are connected to the second gear by fasteners, allowing for the replacement of component blocks of different specifications to change the ratio between the amino acid fermentation broth and the treatment agent.

[0018] 4. In this disc-type separator, the corresponding component blocks rotate and transport a quantitative amount of amino acid fermentation broth and treatment agent in batches through grooves on them. By transporting the amino acid fermentation broth and treatment agent in quantitative batches, the ratio of amino acid fermentation broth to treatment agent remains the same under the premise of continuous transportation and sufficient supply, thereby controlling the quality of the amino acid fermentation broth processed in the same batch.

[0019] 5. This disc-type separator, in which the stirring block rotates, drives the amino acid fermentation broth and the treatment agent in the mixing tube to carry out preliminary mixing, accelerating the reaction rate between the amino acid fermentation broth and the treatment agent. Through treatment, impurities such as cell debris and proteins in the amino acid fermentation broth are gathered, facilitating subsequent separation. In addition, the rotation of the stirring block drives the moving block. The through holes on the moving block and the fixed block are continuously interlaced due to the rotation of the moving block, so as to realize that the amino acid fermentation broth and the treatment agent are temporarily kept in the mixing tube to provide a short mixing space. Furthermore, the rotation of the moving block realizes the intermittent feeding of amino acid fermentation broth and treatment agent, avoiding the excessive amount of pre-treated amino acid fermentation broth in the separator body, which would cause the separator body to overload.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0029] Please see Figure 1-5 A disc-type separator includes a separator body 1, with a feed pipe 11 and a discharge pipe 12 fixedly connected to the upper end of the separator body 1; and a pretreatment component, which is disposed between the separator body 1 and the feed pipe 11. The pretreatment component is used for pretreatment of amino acid fermentation broth. The pretreatment component includes a mounting shell 2, a mixing pipe 3, and a drive motor 44. The mounting shells 2 are symmetrically arranged. A support column 13 is fixedly connected to the separator body 1. Each mounting shell 2 and the drive motor 44 is fixedly connected to the support column 13. The output end of the drive motor 44 is connected to the components in the mounting shell 2 and the mixing pipe 3 respectively. The mixing pipe 3 is fixedly connected to the feed pipe 11. The separator body 1 and the pretreatment component are arranged to achieve the continuous pretreatment and separation steps of the amino acid fermentation broth before processing, thereby reducing processing steps and improving processing efficiency.

[0030] The drive motor 44 has a first gear 4 fixedly connected to its output end. The first gear 4 is symmetrically meshed with a second gear 41. The second gear 41 is rotatably connected to a connecting block 5. The connecting block 5 is connected to the mounting shell 2 by fasteners. The second gear 41 is connected to a component block 51 by fasteners. The component block 51 is tightly fitted to and rotatably connected to the inner wall of the mounting shell 2. The fasteners include, but are not limited to, bolts, and are existing mature technologies. Corresponding fasteners are respectively set on the side walls of the mounting shell 2 and the connecting block 5, and at the ends of the second gear 41 and the component block 51. The drive motor 44 drives the first gear 4 to rotate through its output shaft. The first gear 4 meshes with the corresponding second gear 41. The second gear 41 drives the component block 51 to rotate. During rotation, the corresponding component block 51 transports a quantitative amount of amino acid fermentation liquid and treatment agent in batches through its grooves. By transporting the amino acid fermentation liquid and treatment agent in quantitative batches, the ratio of amino acid fermentation liquid to treatment agent remains the same under the premise of continuous transportation, and the quality of the amino acid fermentation liquid processed in the same batch is controlled.

[0031] The treatment agent is a flocculant such as chitosan or aluminum sulfate, which promotes the aggregation of cell debris, proteins and other impurities, making them easier to separate later.

[0032] Each mounting shell 2 is fitted with a sealing gasket between itself and the connecting block 5. A heating wire is embedded in the inner wall of each mounting shell 2 and electrically connected to a power source. A connecting end 21 is fixedly connected to the upper end of each mounting shell 2, and a conveying pipe 22 is fixedly connected to the bottom of each mounting shell 2. Each conveying pipe 22 is fixedly connected to the mixing pipe 3. After processing the same batch of amino acid fermentation broth, the connecting block 5 is separated from the mounting shell 2 using fasteners. After separation, the mounting shell 2 and the component blocks 51 are manually cleaned to prevent contamination during subsequent processing. The mixing of amino acid fermentation broth affects the quality of subsequent batches of amino acid fermentation broth. The component block 51 is connected to the second gear 41 by fasteners, allowing for the replacement of component blocks 51 of different specifications. Different specifications of component blocks 51 refer to component blocks 51 with different sized grooves. The heating wire inside the mounting shell 2 is energized and heated after the device is in operation, heating the amino acid fermentation broth flowing through the mounting shell 2 to deactivate the enzymes in the amino acid fermentation broth. The target substance, deactivated amino acids, is placed in the mixture. A quantitative amount of amino acid fermentation broth and treatment agent are sent into the mixing tube 3 through the delivery tube 22.

[0033] The first gear 4 is fixedly connected to a first bevel gear 42, which meshes with a second bevel gear 43. The second bevel gear 43 is rotatably connected to the mixing tube 3. A stirring block 6 is fixedly connected to the bottom of the second bevel gear 43, and each stirring block 6 is in close contact with the inner wall of the mixing tube 3. A movable block 61 is fixedly connected to the bottom of the stirring block 6, which is rotatably connected to the inner wall of the mixing tube 3. A fixed block 62 abuts against the bottom of the movable block 61, and the fixed block 62 is fixedly connected to the mixing tube 3. Both the movable block 61 and the fixed block 62 have through holes, and their overall structures are identical. When the first gear 4 rotates, it drives the first bevel gear 42 to rotate. The first bevel gear 42 meshes with the second bevel gear 43. The bevel gear 43 drives the stirring block 6 to rotate. The stirring block 6, in its rotation, drives the amino acid fermentation broth and the treatment agent in the mixing tube 3 to undergo preliminary mixing, accelerating the reaction rate between the amino acid fermentation broth and the treatment agent. Through treatment, impurities such as cell debris and proteins in the amino acid fermentation broth are gathered, facilitating subsequent separation. In addition, the rotation of the stirring block 6 drives the movable block 61. The through holes on the movable block 61 and the fixed block 62 are continuously interlaced due to the rotation of the movable block 61, which allows the amino acid fermentation broth and the treatment agent to stay briefly in the mixing tube 3, providing a short mixing space. Furthermore, the rotation of the movable block 61 enables intermittent feeding of the amino acid fermentation broth and the treatment agent, avoiding excessive pre-treated amino acid fermentation broth in the separator body 1, which could lead to overload of the separator body 1.

[0034] It is worth noting that the separator body 1 is based on existing mature technology. The separator body 1 consists of an electrical variable frequency speed control part, including a variable frequency speed control motor, a frequency converter, an operator, and a variable frequency control operation box, as well as mechanical parts such as a disc assembly, disc rack, drum, vertical shaft, machine body, machine cover, and machine base. The shaft of the variable frequency speed control motor is directly connected to the vertical shaft. This variable frequency speed control disc separator can achieve the effects of simplified mechanism, easy start-up, selection of optimal operating speed, convenient maintenance, and energy saving. The separator body 1 has been disclosed in the existing variable frequency speed control disc separator CN 2936437Y, and will not be described in detail here.

[0035] Working principle: The drive motor 44 drives the first gear 4 to rotate via the output shaft. The first gear 4 meshes with the corresponding second gear 41, which drives the component block 51 to rotate. During rotation, the component block 51 transports a quantitative amount of amino acid fermentation broth and treatment agent in batches through its grooves. By quantitatively transporting the amino acid fermentation broth and treatment agent in batches, and ensuring continuous transport, the ratio of amino acid fermentation broth to treatment agent remains constant under sufficient supply conditions. This controls the quality of the same batch of amino acid fermentation broth. After processing, the connecting block 5 is separated from the mounting shell 2 using fasteners. After separation, the mounting shell 2 and components such as the component block 51 are manually cleaned to prevent mixing with the amino acid fermentation broth from the next batch, which could affect the quality of subsequent batches. The component block 51 is connected to the second gear 41 by fasteners, allowing for the replacement of component blocks 51 of different specifications (different specifications refer to component blocks 51 with different sized grooves). The heating wire inside the mounting shell 2 is energized and heated after the device is operational, heating the amino acid fermentation broth flowing through the mounting shell 2 to stimulate the enzymes in the amino acid fermentation broth. To prevent the inactivation of the target amino acid, a measured amount of amino acid fermentation broth and treatment agent are fed into the mixing tube 3 through the delivery pipe 22. The first gear 4 rotates, driving the first bevel gear 42 to rotate. The first bevel gear 42 meshes with the second bevel gear 43, which in turn drives the stirring block 6 to rotate. The rotating stirring block 6 initiates the mixing of the amino acid fermentation broth and treatment agent within the mixing tube 3, accelerating the reaction rate between them. This process also helps to gather impurities such as cell debris and proteins in the amino acid fermentation broth, facilitating subsequent separation. Furthermore, the rotation of the stirring block 6... The rotating block 61 drives the movable block 61. The through holes on the movable block 61 and the fixed block 62 are continuously interlaced due to the rotation of the movable block 61, so as to provide a short mixing space for the amino acid fermentation liquid and the treatment agent to stay briefly in the mixing tube 3. The rotation of the movable block 61 also enables the intermittent feeding of the amino acid fermentation liquid and the treatment agent, avoiding excessive pre-treated amino acid fermentation liquid in the separator body 1, which would cause the separator body 1 to be overloaded. The arrangement of the separator body 1 and the pre-treatment component enables the continuous realization of the pre-treatment and separation steps of the amino acid fermentation liquid before processing, reducing the number of processing steps and improving processing efficiency.
