Description

Technical Field

[0001] This application relates to the field of fermentation broth filtration and sterilization technology, and in particular to a separation and sterilization device. Background Technology

[0002] In the treatment of fermentation broth in biotechnology and industrial production, it is necessary to extract the liquid substances (containing enzymes and bioactive substances) from the fermentation broth and discard the solid waste (bacterial cells and insoluble culture medium). Before disposal, the solid waste needs to be sterilized. The solid waste must be manually transported from the separation device to the sterilization device, sterilized, and then transferred for disposal, involving two transfer operations, which is cumbersome and reduces processing efficiency. At the same time, during manual transfer, operators are prone to direct contact with the solid waste, posing biosafety risks (such as bacterial leakage) and cross-contamination.

[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0004] Therefore, it is necessary to address the issue of solid waste requiring manual handling from the separation device to the sterilization device, followed by sterilization and then disposal, involving two transfer operations that are cumbersome and reduce processing efficiency. Furthermore, during manual transfer, operators are prone to direct contact with solid waste, posing biosafety risks (such as bacterial leakage) and cross-contamination. Therefore, a separation and sterilization device should be provided.

[0005] A separation and sterilization device, comprising:

[0006] A separation device, comprising an inlet, a first outlet, and a second outlet, wherein the inlet is used to introduce the mixture to be separated, the first outlet is used to separate a first component, and the second outlet is used to separate a second component; and

[0007] The processing device includes an openable and closable receiving component and a sterilization component. The sterilization component is disposed on the receiving component, and the receiving component is movably connected to the separation device so that the opening of the receiving component faces or is away from the second discharge port.

[0008] In one embodiment, the receiving component is rotatably connected to the separating device.

[0009] In one embodiment, the receiving component includes a rotary driver, a transmission mechanism, and a container. The main body of the rotary driver is fixed to the separating device, and the output end of the rotary driver is driven to the transmission mechanism. The transmission mechanism is rotatably connected to the separating device and drively connected to the container. The rotary driver is used to drive the container to rotate through the transmission mechanism so that the opening of the container faces or is away from the second discharge port.

[0010] In one embodiment, the transmission mechanism includes a rotating shaft, a first gear, and a second gear. The first gear is sleeved on the output end of the rotary driver. The rotating shaft is rotatably connected to the separating device. The second gear is sleeved on the rotating shaft. The second gear and the first gear are meshed and connected in a transmission manner. The rotating shaft is fixed on the container.

[0011] In one embodiment, the receiving component includes:

[0012] The main body has the opening and a receiving cavity communicating with the opening. The main body is movably connected to the separation device so that the opening faces or is away from the second discharge port.

[0013] A flipping mechanism, which is connected to the main body and located outside the receiving cavity;

[0014] A cover, which is flipped and connected to the body by the flipping mechanism, so as to expose or close the opening under the drive of the flipping mechanism.

[0015] In one embodiment, the flipping mechanism includes an arc-shaped guide rail and a guide rod. The arc-shaped guide rail is connected to the main body and located outside the receiving cavity. The arc-shaped guide rail has a first end and a second end along its own extending direction. The guide rod is driven and engaged with the arc-shaped guide rail. The guide rod is connected to the cover body, which is located outside the arc-shaped guide rail. The guide rod moves towards the first end or the second end under the action of the arc-shaped guide rail to drive the cover body to flip, thereby exposing the opening or closing the opening.

[0016] In one embodiment, the separation device includes a frame and a filter, the filter being disposed on the frame, the filter having an inlet, a first outlet and a second outlet, the second outlet being disposed at the bottom of the filter along the height direction of the frame, and the receiving component being movably connected to the bottom of the filter.

[0017] In one embodiment, the separation and sterilization device further includes a collector for collecting a second component within the receiving component when the opening of the receiving component is away from the second discharge port.

[0018] In one embodiment, the sterilization component includes a heating element disposed on the receiving component.

[0019] In one embodiment, the heating element includes an electromagnetic heating plate disposed at the bottom of the receiving assembly.

[0020] During operation, when the mixture to be separated (solid-liquid mixture) is introduced through the inlet, the separation device discharges and collects the first component (enzyme-containing liquid) from the first outlet, while the second component (solid waste such as bacterial cells) is discharged from the second outlet. The receiving component opens, and the receiving component of the processing device moves relative to the separation device, so that its opening faces the second outlet. The second component falls directly into the opening of the receiving component. When the opening of the receiving component closes, the sterilization component sterilizes the second component within it. Because the second component separated by the separation device can fall directly into the opening of the receiving component of the processing device, solid waste does not need to be manually transported from the separation device to the independent sterilization device. Instead, it directly enters the processing device for heating and sterilization after exiting the separation device, eliminating a transfer operation, improving processing efficiency, reducing contact between solid waste and operators, and reducing biosafety risks and cross-contamination.

Detailed Implementation

[0025] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0026] In the treatment of fermentation broth in biotechnology and industrial production, it is necessary to extract the liquid substances (including enzymes and bioactive substances) from the fermentation broth and discard the solid waste (bacterial cells and insoluble culture medium). Before disposal, the solid waste needs to be sterilized. The solid waste must be manually transported from the separation device to the sterilization device, sterilized, and then transferred for disposal, involving multiple transfer operations, which is cumbersome and reduces processing efficiency. At the same time, during manual transfer, operators are prone to direct contact with the solid waste, posing biosafety risks (such as bacterial leakage) and cross-contamination.

[0027] Based on the above issues, please refer to Figure 1 This application provides a separation and sterilization device 100, including a separation device 10 and a processing device 20. The separation device 10 is provided with an inlet, a first outlet, and a second outlet. The inlet is used to introduce the mixture to be separated, the first outlet is used to separate a first component, and the second outlet is used to separate a second component. The processing device 20 includes an openable and closable receiving component 1 and a sterilization component. The receiving component 1 is movably connected to the separation device 10, such that the opening of the receiving component 1 faces or faces away from the second outlet. The sterilization component is disposed on the receiving component 1. It can be understood that when the mixture to be separated (solid-liquid mixture) is introduced from the inlet, the separation device 10 discharges and collects the first component (enzyme-containing liquid) from the first outlet, while the second component (solid waste such as bacterial cells) is discharged from the second outlet. When the opening of the receiving component 1 is opened, the receiving component 1 of the processing device 20 moves relative to the separating device 10, so that the opening of the receiving component 1 faces the second discharge port. The second component falls directly into the opening of the receiving component 1. When the opening of the receiving component 1 is closed, the sterilization component sterilizes the second component in the receiving component 1. Because the second component separated by the separating device 10 can fall directly into the opening of the receiving component 1 of the processing device 20, solid waste does not need to be manually transported from the separating device 10 to the independent sterilization device. Instead, it directly enters the processing device 20 for heating and sterilization after exiting the separating device 10, eliminating one transfer operation, improving processing efficiency, reducing contact between solid waste and operators, and reducing the risk of biosafety and cross-contamination.

[0028] First, let's introduce the connection method between the receiving component 1 and the separating device 10:

[0029] In an optional embodiment, the receiving component 1 can be rotatably connected to the separating device 10 about an axis. For example, the opening of the receiving component 1 can be rotated to align with the second discharge port, and solid waste falls into the opening of the receiving component 1. Alternatively, the receiving component 1 can be slidably connected to the separating device 10, sliding to align with the second discharge port to receive solid waste, or sliding away from the second discharge port.

[0030] In some embodiments, the receiving component 1 is rotatably connected to the separating device 10. The rotatable connection method has a simple structure, and when the opening of the receiving component 1 is rotated to face away from the second discharge port, it is convenient to dump the sterilized solid waste and facilitate unloading.

[0031] Please see Figure 1 In some embodiments, the receiving component 1 includes a rotary driver 11, a transmission mechanism 12, and a container 13. The main body 131 of the rotary driver 11 is fixed to the separating device 10. The output end of the rotary driver 11 is driven and connected to the transmission mechanism 12. The transmission mechanism 12 is rotatably connected to the separating device 10 and drively connected to the container 13. The rotary driver 11 drives the container 13 to rotate via the transmission mechanism 12, so that the opening of the container 13 faces or moves away from the second discharge port. The rotary driver 11 enables the opening of the container 13 to be precisely aligned with or quickly moved away from the second discharge port of the separating device 10. The transmission mechanism 12 can convert the high speed and low torque of the rotary driver 11 to low speed and high torque, improving the rotational stability of the container 13, which is especially suitable for large-size containers 13 or heavy-duty conditions.

[0032] In an alternative implementation, the rotary driver 11 may be a servo motor or a stepper motor.

[0033] In optional embodiments, the transmission mechanism 12 may be a gear and rack transmission assembly, a synchronous belt and pulley transmission assembly, or a worm gear transmission assembly, etc.

[0034] Please see Figure 1 In some embodiments, the transmission mechanism 12 includes a rotating shaft 121, a first gear 122, and a second gear 123. The first gear 122 is sleeved on the output end of the rotary driver 11. The rotating shaft 121 is rotatably connected to the separating device 10. The second gear 123 is sleeved on the rotating shaft 121, and the second gear 123 and the first gear 122 are meshed and connected for transmission. The rotating shaft 121 is fixed on the container 13. It can be understood that the output end of the rotary driver 11 drives the first gear 122 to rotate, the first gear 122 drives the second gear 123 to rotate, and then the second gear 123 drives the rotating shaft 121 to rotate, thus rotating the container 13. The meshing characteristics of the first gear 122 and the second gear 123 provide a constant transmission ratio, ensuring more precise control of the rotation angle of the container 13.

[0035] In an optional embodiment, the rotating shaft 121 can be rotatably connected to the separation device 10 via a bearing.

[0036] Next, we will introduce the specific structure of the receiving component 1:

[0037] The receiving component 1 includes a main body 131 and a cover 132. The main body 131 has a receiving cavity and an opening communicating with the receiving cavity, and the cover 132 can open or close the opening.

[0038] In an optional embodiment, the main body 131 and the cover 132 together constitute the container 13 for receiving the component 1.

[0039] In an optional embodiment, the cover 132 can be connected to the main body 131 by means of flipping, rotating, sliding, pivoting, hinge, etc.

[0040] Please see Figure 1 In some embodiments, the receiving component 1 includes a main body 131, a flipping mechanism 133, and a cover 132. The main body 131 has an opening and a receiving cavity communicating with the opening. The main body 131 is movably connected to the separating device 10 so that the opening faces or faces away from the second discharge port. The flipping mechanism 133 is connected to the main body 131 and located outside the receiving cavity. The cover 132 is flipped and connected to the main body 131 via the flipping mechanism 133, so that the opening is exposed or closed under the drive of the flipping mechanism 133. The cover 132 forms a tight fit with the edge of the opening of the main body 131 through the flipping mechanism 133, completely sealing the receiving cavity during sterilization. After the cover 132 is closed, the solid waste is completely isolated from the external environment, avoiding the risk of bacterial leakage due to human contact. The flipping mechanism 133 can be linked with the main body 131. When the main body 131 moves relative to the separation device 10 so that the opening is aligned with the second discharge port, the flipping mechanism 133 automatically opens the cover. When the main body 131 moves relative to the separation device 10 so that the opening is away from the second discharge port, the flipping mechanism automatically closes the cover, realizing an automated process of separation → receiving → closing.

[0041] In optional implementations, the flipping structure can be a hinged structure or a guide rail structure, etc.

[0042] Please see Figure 1 and Figure 2In some embodiments, the flipping mechanism 133 includes an arc-shaped guide rail 1331 and a guide rod 1332. The arc-shaped guide rail 1331 is connected to the main body 131 and located outside the receiving cavity. The arc-shaped guide rail 1331 has a first end 1331a and a second end 1331b along its extension direction. The guide rod 1332 is driven and engaged with the arc-shaped guide rail 1331 and is connected to the cover 132. The cover 132 is located outside the arc-shaped guide rail 1331. Under the action of the arc-shaped guide rail 1331, the guide rod 1332 moves toward the first end 1331a or the second end 1331b to drive the cover 132 to flip, thereby exposing or closing the opening. By guiding the movement of the guide rod 1332 through a preset arc-shaped trajectory, there is no need for complex transmission components (such as gears, connecting rods, etc.), the structure is simple, occupies little space, and is suitable for installation in a limited space outside the receiving cavity. The curvature of the arc-shaped guide rail 1331 can be precisely designed according to the opening angle to ensure that the cover 132 moves along a fixed trajectory when it is flipped, avoiding shaking or displacement and ensuring the sealing when the opening is closed.

[0043] Next, the structure of the sterilization component will be described: In an optional embodiment, the sterilization component may be a heat sterilization component or a radiation sterilization component, etc.

[0044] In some embodiments, the sterilization assembly includes a heating element disposed on the receiving assembly 1. The heating element enables high-temperature sterilization, provides reliable sterilization results, has a wide range of applications, and features a simple structure that facilitates integration.

[0045] In optional embodiments, the heating element may be a heating coil, a heating film, a heating wire, or a heating plate, etc.

[0046] In some embodiments, the heating element includes an electromagnetic heating plate disposed at the bottom of the receiving component 1. The electromagnetic heating plate has a large heating area, enabling large-area heating of the receiving component 1 and improving sterilization efficiency.

[0047] In an optional embodiment, an electromagnetic heating plate is disposed at the bottom of the body 131 of the container 13.

[0048] The separation device 10 will be described below:

[0049] Please see Figure 1In some embodiments, the separation device 10 includes a frame 101 and a filter 102. The filter 102 is mounted on the frame 101 and has an inlet, a first outlet, and a second outlet. Along the height of the frame 101, the second outlet is located at the bottom of the filter 102, and a receiving assembly 1 is movably connected to the bottom of the filter 102. The frame 101 provides a stable mounting foundation for the filter 102 and components such as the receiving assembly 1, ensuring reliable long-term operation. The second outlet at the bottom of the filter 102 and the receiving assembly 1 movably connected to the bottom of the filter 102 utilize gravity to allow the separated solid waste to fall naturally to the receiving assembly 1, reducing additional power consumption. Simultaneously, the vertical layout along the height of the frame 101 shortens the material transport path, avoiding sedimentation or residue that may occur during horizontal transport.

[0050] In optional embodiments, filter 102 may be a plate and frame filter 102, a centrifugal filter 102, or a membrane filter 102, etc.

[0051] In some embodiments, the separation and sterilization device 100 further includes a collector for collecting the second component within the receiving component 1 when the opening of the receiving component 1 faces away from the second discharge port. The collector is configured to collect the sterilized solid waste. After the receiving component 1 has completed sterilization, the opening of the receiving component 1 moves away from the second discharge port and faces the collector, and the receiving component 1 automatically unloads, releasing the sterilized solid waste directly into the collector. This process eliminates the need for manual contact with the material, avoiding the risk of cross-contamination associated with traditional manual handling.

[0052] The working principle of the separation and sterilization equipment 100 of this application will be described in detail below with specific embodiments: Please refer to Figure 1 and Figure 2The solid-liquid mixture to be separated is added to the inlet of the filter 102 of the separation device 10. The filter 102 separates the solid-liquid mixture, with the fermentation broth containing enzymes exiting from the first outlet and the solid waste exiting from the second outlet. The guide rod 1332 of the flipping mechanism 133 of the container 13 moves along the arc-shaped guide rail 1331 to the first end 1331a. The guide rod 1332 drives the cover 132 to flip open relative to the main body 131, exposing the opening of the main body 131. At the same time, the rotary drive 11 of the receiving component 1 drives the first gear 122 to drive the second gear 123 to rotate, and then the rotating shaft 121 drives the container 13 to rotate until the opening of the container 13 is aligned with the second outlet. The solid waste falls from the second outlet into the opening of the main body 131 of the container 13. Next, the guide rod 1332 of the tilting mechanism 133 of container 13 moves along the arc-shaped guide rail 1331 to the second end 1331b. The guide rod 1332 drives the cover 132 to tilt and close relative to the main body 131, closing the opening of the main body 131. The electromagnetic heating plate starts heating to sterilize the solid waste in container 13. After sterilization, the rotary driver 11 of receiving component 1 drives the first gear 122 to rotate the second gear 123, and then the rotating shaft 121 drives the container 13 to rotate so that the opening of container 13 faces away from the second discharge port and towards the collection container 13. The guide rod 1332 of the tilting mechanism 133 of container 13 moves again along the arc-shaped guide rail 1331 to the first end 1331a. The guide rod 1332 drives the cover 132 to tilt and open relative to the main body 131, exposing the opening of the main body 131, so that the sterilized solid waste is poured into the collection container 13.
