Description

Technical Field

[0001] This invention relates to the field of vaccine separator technology, specifically to a vaccine separator and its working method that utilizes vapor phase to achieve self-sterilization and cleaning functions. Background Technology

[0002] Vaccine separators are equipment developed primarily for the separation of microbial cells in the field of microecology. During the production process, the oil phase and water phase are separated by rotation (centrifugal force). For details, please refer to the relevant content mentioned in publication number CN112190979A. Essentially, it is a centrifuge.

[0003] To avoid contaminating the bacteria, a thorough cleaning process is required before separating different bacteria. This process is used to completely inactivate any residues from the previous separation. Conventional cleaning methods primarily use specialized liquid media. However, this type of cleaning method has the following related problems:

[0004] 1. The large consumption results in some residual liquid inside the body, which poses a risk of contaminating the next batch of bacteria;

[0005] 2. To avoid residual bacteria in the gaps of structural components, it is often necessary to disassemble and reassemble some parts, which results in a long cleaning cycle;

[0006] 3. Taking alcohol mixture as an example, the sterilization effect mainly relies on the property of destroying bacterial proteins, and the internal rotating structure of the machine drives the alcohol mixture to flow. The process is relatively simple and cannot completely guarantee the sterilization effect.

[0007] This application proposes a solution to this problem. Summary of the Invention

[0008] The purpose of this invention is to provide a vaccine separator and its working method that utilizes vapor phase to achieve self-sterilization and cleaning functions. This invention addresses the cleaning operations in vaccine separators, which conventionally rely mainly on liquid cleaning media. The operation process is relatively simple and requires the disassembly and reassembly of some parts to avoid bacterial residue. However, even after cleaning, some residual cleaning liquid still poses a risk of contaminating the next batch of bacteria.

[0009] The objective of this invention can be achieved through the following technical solution: a vaccine separator that utilizes vapor phase to achieve self-sterilization and cleaning function, comprising a vessel body, a motor drive assembly provided on the lower side of the vessel body, and a stirring disk corresponding to the motor drive assembly provided at the bottom of the vessel body, a vapor-liquid dual-path structure corresponding to the stirring disk provided inside the vessel body, and a controller installed on the outside of the vessel body.

[0010] The vapor-liquid dual-path structure includes a directional sleeve, a moving sleeve, a moving guide rod, and a fixed guide rod. The directional sleeve and the fixed guide rod are installed at the top of the vessel body, with the fixed guide rod located inside the directional sleeve. The centers of the directional sleeve, the moving sleeve, the moving guide rod, and the fixed guide rod are on the same vertical axis. The moving guide rod is installed at the center of the stirring plate. The moving sleeve is slidably mounted on the moving guide rod. Steam injection ports are provided at the top and bottom of the fixed guide rod and the fixed guide rod has a primary gas port. The moving guide rod has a secondary gas port and a tertiary gas port along the top-to-bottom direction.

[0011] The further configuration includes: a liquid outlet pipe and a liquid injection pipe installed on the upper side of the outer wall of the vessel body, and a slag discharge pipe installed on the lower side of the vessel body; each of the liquid outlet pipe, liquid injection pipe, and slag discharge pipe is equipped with a solenoid valve.

[0012] The following configuration is further provided: the injection pipe penetrates the vessel body and is connected to the interior of the directional sleeve, and the primary air port is positioned higher than the injection pipe.

[0013] A further configuration is provided: a piston block is slidably mounted on the guide rod along the vertical direction, and the piston block is slidably connected to the inner wall of the directional sleeve.

[0014] The configuration is further defined as follows: the fixed guide rod and the moving guide rod are slidably connected at their respective ends in the vertical direction; a float is slidably installed on the outer wall of the moving guide rod located on the upper side of the moving sleeve; and multiple support plates are installed on the outer wall of the moving sleeve, with the support plates matching the inner wall of the vessel.

[0015] A further configuration is provided: a fixed cone block is fixedly installed on the moving guide rod, and the fixed cone block is located at the middle position between the stirring disc and the moving sleeve.

[0016] A further configuration is provided: a fixed cone block is fixedly installed on the moving guide rod, and the fixed cone block is located at the middle position between the stirring disc and the moving sleeve.

[0017] The following configuration is further provided: a rotating sleeve is rotatably installed at the center point of the bottom of the vessel body; the moving guide rod extends downward into the rotating sleeve; a limiting structure is provided between the moving guide rod and the rotating sleeve; and the opening position of the third-stage air port corresponds to the position on the upper side of the rotating sleeve.

[0018] This invention also proposes a working method for a vaccine separator that utilizes the vapor phase to achieve self-sterilization and cleaning functions, comprising a separation action and a cleaning action, wherein the cleaning action is performed after the separation action is completed, and includes the following steps:

[0019] Step 1: Use a solenoid valve to seal the liquid outlet pipe, liquid injection pipe and slag discharge pipe, and inject high-temperature medium steam into the reactor body through the steam injection port at the top of the fixed guide rod and the bottom of the moving guide rod, so as to generate a high-temperature and high-pressure environment inside the reactor body through the high-temperature medium steam.

[0020] Step 2: Establish a control system that links the injection process of high-temperature medium steam and the operation process of the solenoid valve through the controller. Based on the control system, monitor the temperature and pressure environment in the independent steam chamber and the mixed liquid chamber inside the vessel in real time and obtain two sets of real-time temperature parameters and real-time pressure parameters. Control the injection process of high-temperature medium steam and the operation process of the solenoid valve in reverse according to the real-time temperature parameters and real-time pressure parameters.

[0021] Step 3: In step 2, the injection process of high-temperature medium steam is used to change two sets of real-time temperature parameters and real-time pressure parameters, and to change the movement mode of piston block, agitator, and moving sleeve for multi-position steam cleaning. During the cleaning action, the agitator is either in a state of maintaining rotation or stopping rotation.

[0022] The present invention has the following beneficial effects:

[0023] 1. Regarding the cleaning process during the use of the vaccine separator, this invention adopts vapor phase cleaning. The reason is that vaporous substances have higher diffusion and permeability than liquid substances, which can more effectively penetrate into small gaps and hard-to-reach areas, thereby cleaning these parts more thoroughly. In terms of material consumption, while achieving the same cleaning effect, the consumption of vaporous substances is much less than that of liquid substances. In addition, the vapor medium has better heat dissipation and evaporation effects, and has a better inactivation effect on residual bacteria during the separation process.

[0024] 2. In conjunction with the above, this invention adopts a dual-path structure for the steam injection process. Essentially, it forms two flow modes of high-temperature steam media. Combined with the injection mode of the bacterial mixture in the separation action of the vaccine separator, the high pressure and high temperature conditions generated during the injection of high-temperature steam media further change the temperature and pressure environment inside the vessel. Furthermore, the temperature and pressure environment are used to control the injection process of high-temperature steam media in reverse, enabling targeted steam inactivation at different locations, thus achieving a better cleaning effect.

[0034] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1: For the cleaning operation in a vaccine separator, conventional methods mainly use liquid cleaning media. The operation process is relatively simple and requires disassembling some parts to avoid bacterial residue. However, some cleaning liquid remains after cleaning, posing a risk of contaminating the next batch of bacteria. The following technical solution is proposed to address this issue:

[0036] Reference Figures 1-7 The vaccine separator that utilizes the vapor phase to achieve self-sterilization and cleaning function in this embodiment includes a vessel body 1. A motor drive assembly 10 is provided on the lower side of the vessel body 1, and a stirring disk 8 corresponding to the motor drive assembly 10 is provided at the bottom of the vessel body 1. A vapor-liquid dual-path structure corresponding to the stirring disk 8 is provided inside the vessel body 1, and a controller 2 is installed on the outside of the vessel body 1.

[0037] The dual-path vapor-liquid structure includes a directional sleeve 4, a movable sleeve 7, a movable guide rod 6, and a fixed guide rod 11. The directional sleeve 4 and the fixed guide rod 11 are installed at the top of the vessel body 1, with the fixed guide rod 11 located inside the directional sleeve 4. The centers of the directional sleeve 4, the movable sleeve 7, the movable guide rod 6, and the fixed guide rod 11 are on the same vertical axis. The movable guide rod 6 is installed at the center of the stirring plate 8. The movable sleeve 7 is slidably mounted on the movable guide rod 6. Steam injection ports 3 are provided at the top of the fixed guide rod 11 and the bottom of the movable guide rod 6. A primary air port 401 is provided on the guide rod 11, and a secondary air port 402 and a tertiary air port 403 are provided on the moving guide rod 6 from top to bottom. A liquid outlet pipe 101 and a liquid injection pipe 103 are respectively installed on the upper side of the outer wall of the vessel body 1, and a slag discharge pipe 102 is installed on the lower side of the vessel body 1. Solenoid valves are provided on the liquid outlet pipe 101, the liquid injection pipe 103 and the slag discharge pipe 102. The liquid injection pipe 103 penetrates the vessel body 1 and is connected to the inside of the directional sleeve 4. The primary air port 401 is located higher than the liquid injection pipe 103.

[0038] Working principle: When the overall device is performing separation, the bacterial mixture is injected into the vessel 1 through the injection pipe 103, and the stirring plate 8 is driven to rotate at high speed by the motor drive assembly 10. The motor drive assembly 10 is essentially a belt drive, and the rotating sleeve 9 is rotated by the motor structure. This process will not be explained in detail. The bacterial mixture is centrifuged by the rotation of the stirring plate 8. The liquid outlet pipe 101 is set up vertically according to the centrifugation stratification, and the slag discharge pipe 102 discharges the waste liquid after centrifugation. This part belongs to the basic principle of the vaccine separator and will not be explained in detail.

[0039] The dual-channel structure of vapor and liquid also plays an auxiliary role in the separation process. Specifically, when the bacterial mixture is mainly injected into the directional sleeve 4 through the injection pipe 103, the float 5 floats up and down with the flow of the bacterial mixture to match the bottom position of the directional sleeve 4. The purpose is to avoid large fluctuations in the liquid surface when the bacterial mixture is injected into the vessel body 1. The moving sleeve 7 is pressed tightly against the fixed cone block 13 by the pressure of the bacterial mixture, forming a relatively hollow state inside for "temporary storage" of the bacterial mixture. When the bacterial mixture completes the separation process, the upper oil phase is kept relatively stable, while the lower aqueous phase is in a relatively fluctuating state. The purpose is to ensure the contact "space" between the bacteria and substances such as demulsifiers.

[0040] Example 2: This example is based on the separation action in Example 1, and proposes the following working plan:

[0041] A piston block 12 is slidably mounted on the fixed guide rod 11 in the vertical direction. The piston block 12 is slidably connected to the inner wall of the directional sleeve 4. The fixed guide rod 11 and the moving guide rod 6 are slidably connected in the vertical direction at their respective ends. A float 5 is slidably mounted on the outer wall of the moving guide rod 6 on the upper side of the moving sleeve 7. Multiple support plates are mounted on the outer wall of the moving sleeve 7. The support plates are matched with the inner wall of the vessel body 1. A fixed cone block 13 is fixedly mounted on the moving guide rod 6. The fixed cone block 13 is located in the middle of the stirring plate 8 and the moving sleeve 7. A rotating sleeve 9 is rotatably mounted at the center point of the bottom of the vessel body 1. The moving guide rod 6 extends downward into the interior of the rotating sleeve 9. A limit structure is provided between the moving guide rod 6 and the rotating sleeve 9. The opening position of the third-stage air port 403 corresponds to the upper position of the rotating sleeve 9.

[0042] Solution Description: This embodiment mainly focuses on the cleaning process after the separation operation. Specifically, it addresses the injection process of the bacterial mixture and the discharge process of the separated substances. Taking the injection pipe 103, the outlet pipe 101, and the slag discharge pipe 102 as examples, the overall cleaning process includes the following parts:

[0043] S1: After the separation action is completed, the solenoid valve at the slag discharge pipe 102 is opened to discharge the separated waste liquid. Then, the solenoid valves on the liquid injection pipe 103, liquid outlet pipe 101 and slag discharge pipe 102 are all in the distributed state. In this state, high temperature steam medium is injected simultaneously through the air injection port 3 on the fixed guide rod 11 and the moving guide rod 6. For example, taking alcohol steam as an example, when the high temperature steam medium enters, it enters the independent steam chamber 104 and the mixed liquid chamber 105 respectively, and sterilization is carried out by the high temperature steam medium.

[0044] S2: Based on S1, as the amount of high-temperature steam medium in the independent steam chamber 104 gradually increases until its internal pressure rises and exceeds the pressure in the mixed liquid chamber 105, the piston block 12 is pushed down to the lower side of the injection pipe 103. During this process, the solenoid valve at the injection pipe 103 is opened instantly. The high-temperature steam medium injected into the mixed liquid chamber 105 can be used to sterilize the mixture while simultaneously rinsing the residual bacterial mixture inside the injection pipe 103.

[0045] S3: Conversely, when the piston block 12 is always located on the upper side of the injection pipe 103, when the high-temperature steam medium is continuously injected, the solenoid valve on the liquid outlet pipe 101 or the slag discharge pipe 102 can be opened to flush the inside of the liquid outlet pipe 101 or the slag discharge pipe 102.

[0046] Regarding S1~S3, when high-temperature steam medium is injected into the mixing tank 105, due to the heat exchange process, part of the high-temperature steam medium liquefies, and the injection process of the high-temperature steam medium also causes the float 5 to move up and down. However, the specific upward movement of the moving sleeve 7 and the agitator 8 is as follows:

[0047] S4: The primary air port 401 on the fixed guide rod 11 is in a single position and is only used to change the movement of the piston block 12. The secondary air port 402 and the tertiary air port 403 on the moving guide rod 6 serve as outlets for the high-temperature steam medium. However, it should be noted that the pressure generated when the high-temperature steam medium is injected will drive the moving guide rod 6 to move upward. Specifically, the high-temperature steam medium first leaks out from the secondary air port 402, which increases the amount of high-temperature steam medium inside the moving sleeve 7, thereby causing the moving sleeve 7 to move upward. In addition, as the high-temperature steam medium is continuously injected, the pressure generated will push the stirring plate 8 upward, so the tertiary air port 403 will also serve as an outlet for the high-temperature steam medium. In this state, the moving sleeve 7 loses the pressure of the high-temperature steam medium and moves downward to reset. This process is repeated in this way. While ensuring the continuous injection of the high-temperature steam medium, the support plate on the moving sleeve 7 scrapes the inner wall of the vessel 1, which also prevents the liquefied high-temperature steam medium from sticking to the wall.

[0048] In the context of the limiting structure: the motor drive assembly 10 primarily drives the rotating sleeve 9 to rotate, while the moving guide rod 6, located below the agitator 8, must not only have the ability to move up and down but also to rotate synchronously. This is explained in reference to... Figure 5 To explain, multiple vertically arranged limiting strips are installed on the outer wall of the moving guide rod 6 located on the lower side of the stirring plate 8, and the rotating sleeve 9 has a limiting groove inside that corresponds to the limiting strips, thus having the functions of vertical movement and synchronous rotation.

[0049] Example 3: Combining Example 1 and Example 2, the following technical solution is generated:

[0050] The working method of a vaccine separator that utilizes vapor phase to achieve self-sterilization and cleaning functions includes a separation action and a cleaning action. The cleaning action is performed after the separation action is completed and includes the following steps:

[0051] Step 1: Use a solenoid valve to seal the liquid outlet pipe 101, liquid injection pipe 103 and slag discharge pipe 102, and inject high-temperature medium steam into the reactor body 1 through the steam injection port 3 at the top of the fixed guide rod 11 and the bottom of the moving guide rod 6, so as to generate a high-temperature and high-pressure environment inside the reactor body 1.

[0052] Step 2: Establish a control system for the injection process of high-temperature medium steam and the action process of the solenoid valve through controller 2. Based on the control system, monitor the temperature and pressure environment in the independent steam chamber 104 and the mixed liquid chamber 105 inside the vessel 1 in real time and obtain two sets of real-time temperature parameters and real-time pressure parameters. Control the injection process of high-temperature medium steam and the action process of the solenoid valve in reverse according to the real-time temperature parameters and real-time pressure parameters.

[0053] Step 3: In step 2, the injection process of high-temperature medium steam is used to change two sets of real-time temperature parameters and real-time pressure parameters, and to change the movement mode of piston block 12, agitator 9, and moving sleeve 7 to perform multi-position steam cleaning. During the cleaning action, agitator 8 is either in a state of maintaining rotation or stopping rotation.

[0054] Solution Description: This embodiment summarizes Embodiment 2, but the key lies in the control system. The overall device mainly includes two spaces: an independent steam chamber 104 and a mixed liquid chamber 105. To ensure the normal operation of the cleaning process, the temperature and pressure inside these two spaces will change when high-temperature steam medium is continuously injected. This will be explained in conjunction with S1~S3 of Embodiment 2:

[0055] The real-time temperature and pressure parameters of the two spaces, independent steam chamber 104 and mixed liquid chamber 105, are set as Td, Pd, Th, and Ph, respectively. Td and Pd represent the temperature and pressure values ​​in independent steam chamber 104, and similarly, Th and Ph represent the temperature and pressure values ​​in mixed liquid chamber 105. Since the cleaning action of injection pipe 103 should be taken into consideration first, Pd > Ph is ensured by injecting high-temperature steam medium. However, during this process, the temperature Td in independent steam chamber 104 and mixed liquid chamber 105 needs to be greater than or equal to 95°C. During this process, due to the pressure difference between independent steam chamber 104 and mixed liquid chamber 105, and when injection pipe 103 is opened instantaneously, the high-temperature steam medium remaining in independent steam chamber 104 is used as the driving force to quickly flush away the residual bacterial mixture in injection pipe 103, and independent steam chamber 104 will also complete the high-temperature sterilization action.

[0056] Regarding the cleaning action inside the mixing chamber 105, it is necessary to ensure that Pd < Ph so that the piston block 12 returns to its original position. During the continuous injection of high-temperature steam medium into the mixing chamber 105, sterilization is achieved through the high-temperature steam medium. The sterilization effect can also be improved by the rotation of the stirring plate 8 and the up-and-down movement of the moving sleeve 7 to drive the high-temperature steam medium to flow fully. According to the relevant instructions in Example 2, the solenoid valves on the liquid outlet pipe 101 or the slag discharge pipe 102 are opened to flush them one by one. It should be noted that because a portion of the high-temperature steam medium is discharged instantly, the pressure value in the mixing chamber 105 drops rapidly. Therefore, when opening the solenoid valves on the liquid outlet pipe 101 or the slag discharge pipe 102, it is necessary to further change the pressure value in the independent steam chamber 104 to reduce its internal pressure value.

[0057] Repeat the above steps multiple times until the injection pipe 103, the outlet pipe 101, and the slag discharge pipe 102 have all been sterilized and cleaned.

[0058] In summary, the principle behind using steam cleaning in the vaccine separator's cleaning process is that gaseous media have better permeability and diffusion than liquid media, and also possess superior heat dissipation and evaporation effects. This results in a better inactivation effect on residual bacteria during the separation process. Based on these factors, a dual-path steam-liquid structure is proposed, which essentially involves targeted and localized cleaning of the bacterial mixture during the separation process. This requires real-time interaction between the temperature and pressure environments inside the vessel during the high-temperature steam injection process, ultimately aiming to improve the overall cleaning effect.
