[0027] It should be noted that in this text, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between the entities or operations. Moreover, the terms "include", "contain" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or equipment. Without more limitations, the element defined by the statement "including a" does not exclude the presence of other identical elements in the process, method, article or equipment including the element.

[0028] As Figure 1 shown, the automatic vaccine harvesting device for poultry vaccine production of the application includes the following components: filter assembly 1, vaccine collection body 2, pressure balance valve 3 and sealing connector 4.

[0029] Filter assembly 1 is the core structure of the harvesting device. It is fixed at the vaccine collection outlet position through the sealing connector 4, ensuring that the material passing through can be accurately filtered. It contains a cylindrical rigid frame with double-layer grid structure as filter support frame 101, enhancing the support of filter membrane 107, guaranteeing the filtering effect and service life. In application, the filter support frame 101 can be made of stainless steel material, with high strength and stability, effectively supporting the filter membrane 107 and keeping the shape unchanged during the filtering process.

[0030] The filter membrane 107 in the cylindrical rigid frame is made of soft elastic material and has a circular concave shape. A reinforcing plate 103 is arranged outside the filter membrane 107. During operation, when the liquid is filtered under pressure, the reinforcing plate can disperse and balance the stress on the filter membrane 107, avoiding rupture or deformation caused by excessive local pressure. The material of the filter membrane 107 can be medical silicone rubber or other high-molecular materials with corrosion resistance and elasticity, which can provide sufficient elastic support and are not easy to be damaged, and are suitable for stable filtration under long-term use conditions.

[0031] An annular silica gel buffer pad 104 is arranged at the contact edge of the frame and the filter membrane 107. This not only protects the soft filter membrane 107 from mechanical damage, but also enhances the sealing and stability of the joint between the two, thereby preventing leakage caused by vibration or fluid impact and improving the overall reliability of the equipment operation. The thickness of the annular silica gel buffer pad 104 can be adjusted according to the specific application scenario to meet different specifications.

[0032] The vaccine collection body 2 is an important storage unit in the device, mainly used for storing vaccine mixtures that have been preliminarily processed by centrifugation or sedimentation. Its design should consider accommodating an appropriate amount of liquid without affecting the subsequent process, and usually has a transparent observation window for real-time viewing of the internal state. The bottom of the vaccine collection body 2 can be designed in a conical shape, which is beneficial to discharge all remaining liquid and reduce waste.

[0033] A pressure balance valve 3 is installed at the pipeline between the vaccine collection body 2 and the filter assembly 1. The function of this component is to adjust the pressure difference between the two to maintain a stable liquid inlet flow rate. This feature reduces the impact of instantaneous high pressure on the sensitive filter membrane 107, prolongs the service life, and ensures consistent filtration accuracy. For example, the pressure difference between the inlet and outlet channels can be automatically adjusted by setting appropriate opening and closing thresholds.

[0034] The sealed connector 4 ensures that all interfaces of the entire system meet strict airtight standards and can withstand a certain range of pressure differences. Its manufacturing process must be strictly in accordance with relevant national standards, using high-quality raw materials and precise mechanical processing to achieve the highest level of waterproof and leakproof. For example, for scenarios that need to work in harsh environments for a long time, the sealing ring can be made of special fluoroplastic materials, which have excellent chemical corrosion resistance and can work stably at temperatures ranging from -60°C to +250°C.

[0035] For the above technical scheme, the design of the vaccine automatic harvesting device for poultry vaccine production introduces a reinforcing plate 103 and a ring-shaped silica gel buffer pad 104, effectively sharing and uniformizing the pressure load from two directions, greatly reducing the risk of damage to the fragile filter membrane 107 caused by the rapid increase of external instantaneous pressure. At the same time, the pressure balance valve 3 is used to keep the system inside always within a suitable working pressure range, completely solving the problem of filter membrane 107 deformation caused by excessive pressure difference, ensuring the safe and reliable operation of the entire production process.

[0036] As shown in Figure 1 In one embodiment, the double-layer grid structure in the filter support frame 101 of the vaccine automatic harvesting device for poultry vaccine production further comprises a plurality of radial reinforcing ribs 105. These reinforcing ribs 105 are installed inside the filter support frame 101 and are fixed by reasonable layout and welding to enhance the strength of the support frame. Specifically, the double-layer grid structure not only provides basic support, but also ensures the effective support and flatness of the filter membrane 107, avoiding deformation caused by external vibration or uneven material flow rate.

[0037] In one example, the reinforcing ribs 105 are uniformly arranged along the radial direction of the filter support frame 101. This design can ensure balanced stress distribution in each part, preventing fatigue fracture in some areas due to uneven stress. In addition, the design of the reinforcing ribs 105 can effectively disperse the pressure on the filter membrane 107 to the entire support frame surface, improving the reliability and service life of the system.

[0038] Specifically, the reinforcing ribs 105 can be made of appropriate high-strength metal materials and firmly installed in the double-layer grid structure through welding or bolt connection. This installation method not only provides additional support, but also facilitates later maintenance and replacement. In order to further improve the performance of the system, the thickness and shape of the reinforcing ribs 105 can be optimized to ensure that they can provide sufficient support without excessively increasing the overall weight, while ensuring the working efficiency and running stability of the device.

[0039] As shown in Figure 2 and Figure 3As shown in one embodiment, an automatic vaccine harvesting device for poultry vaccine production according to this application is characterized by densely arranged protrusions 106 on the inner side of a circular concave surface 102 made of a soft elastic material on the filter membrane 107. These protrusions 106 not only enhance structural stability but also help to uniformly transmit pressure from the rigid frame, preventing damage to the filter membrane 107 during stress. This design effectively reduces pressure concentration points on the filter membrane 107 caused by uneven pressure, extending the service life of the filter membrane 107. The circular concave surface 102 is tightly integrated with the filter membrane 107, allowing pressure to be uniformly transmitted from the reinforcing plate 103 to the entire surface of the filter membrane 107. Since the reinforcing plate 103 is located on the outside of the filter membrane 107, this design also ensures the consistency and stability of material flow during filtration.

[0040] Specifically, a layer of soft material can be arranged on the side of the cylindrical rigid frame that contacts the filter membrane 107, and tiny, densely packed protrusions 106 can be machined onto this layer. This soft material layer is fixed to the frame by adhesive or mechanical connection and completely encapsulates the filter membrane 107. When external pressure is applied, the protrusions 106 effectively disperse the pressure and ensure that it acts evenly across the entire surface of the filter membrane 107, thereby protecting the filter membrane 107 from localized excessive pressure. In addition, a reinforcing plate 103 is fixed to the outside by screws or other mechanical fasteners to maintain the stability and sealing of the entire assembly, while an annular silicone buffer pad 104 is installed around the edge of the filter membrane 107 to provide further protection and enhance the tightness of the connection. In this configuration, all components work together to ensure that the mixture within the vaccine collection body 2 undergoes a precise and uniform filtration process.

[0041] like Figure 3 As shown in one embodiment, an automatic vaccine harvesting device for poultry vaccine production according to this application is characterized by an annular silicone buffer pad 104 at the contact point between the frame and the filter membrane 107, with a flexible steel wire ring 108 embedded inside. This design gives the annular silicone buffer pad 104 good elasticity and sealing effect, while avoiding excessive deformation due to external forces. The annular silicone buffer pad 104 is installed on the inner edge of the filter support frame 101, tightly attached between the reinforcing plate 103 and the filter membrane 107. The embedding of the flexible steel wire ring 108 further enhances the stability and flexibility of the buffer pad structure. This structure ensures a stable sealing state under pressure and provides additional support and protection for the filter membrane 107.

[0042] For example, a silicone material with appropriate thickness can be selected to make a ring-shaped buffer pad with a predetermined shape and size, and a flexible steel wire that meets the specific hardness requirement can be pre-processed to a corresponding length to fit into the inner cavity of the ring-shaped buffer pad. After the flexible steel wire is uniformly distributed and firmly embedded in the designated position of the buffer pad, the two together form a complete ring-shaped sealing assembly. This assembly is installed in the appropriate position in the filter assembly 1 through bonding or mechanical fixation, thereby ensuring functional consistency throughout the entire service life. On this basis, the ring-shaped silicone buffer pad 104 can not only provide the necessary sealing effect, but also has enough elasticity to buffer external pressure changes and prevent irreversible deformation due to long-term operation, thereby prolonging the service life of the overall device and improving reliability.

[0043] As shown in Figure 4 In one embodiment, the sealing connector 4 of the automatic vaccine harvesting device for poultry vaccine production of the present application comprises a shock-absorbing rubber layer 401. This design aims to improve the shock resistance of the system and ensure the connection tightness and reliability of the components during device operation. By embedding a shock-absorbing rubber layer 401 in the sealing connector 4, external vibrations can be absorbed and mitigated while maintaining good sealing effect. This layer of rubber not only improves the mechanical strength of the connection site, but also reduces the loosening and leakage problems caused by vibration.

[0044] For example, the sealing connector 4 is specially optimized in design. Specifically, the installation position of this sealing connector 4 is at the junction of the filter support frame 101 and the vaccine collection body 2. Its constituent structure not only includes a conventional sealing assembly, but also specially adds a layered structure made of shock-absorbing rubber material. These materials are usually stacked in multiple layers in the connection area and firmly bonded through special processes, ensuring that they effectively resist vibration for a long time while not affecting the sealing performance.

[0045] The sealing connector 4 effectively deals with various possible mechanical stress changes through physical properties. In particular, under complex operating conditions such as the inevitable vibration and impact conditions during vaccine production, the sealing connector 4 can still maintain high strength connection tightness, ensuring stable system operation. For example, when the circular concave surface 102 filter membrane 107 on the filter support frame 101 is filtering materials, the pressure balance valve 3 adjusts the pressure difference between the inflow and outflow of the mixed liquid, and at this time the connection site needs to withstand periodic load changes; the sealing connector 4 with shock-absorbing rubber layer 401 can exactly exhibit its unique role in these dynamic environments, protecting the connection point from adverse effects.

[0046] As shown in Figure 1As shown, in one embodiment, the vaccine collection body 2 of the automatic vaccine harvesting device for poultry vaccine production of the present application adopts a flexible transition design of the gooseneck pipe 201 near the connection position. This design effectively reduces the impact force transmission between the collection body and the filter assembly 1, protecting the stability and durability of the entire system. The gooseneck pipe 201 is installed at one end of the vaccine collection body 2 near the connection and extends to the position where the filter assembly 1 sealing connector 4 connects. The gooseneck pipe 201 adopts a multi-layer structure design, the outer layer is made of high-toughness, corrosion-resistant polymer material, and the inner layer is soft rubber material with excellent stretchability.

[0047] Specifically, the flexible transition design makes the pipe body have bending and stretching properties, and the pressure fluctuations generated when the material passes through the collection body quickly can be effectively buffered. Through this design, the impact damage caused by direct hard connection between rigid pipes and the leakage risk caused thereby can be avoided, thereby ensuring long-term stable operation of the system. In addition, the connection between the gooseneck pipe 201 and the vaccine collection body 2 is realized through a customized flange connector, so that the entire connection part not only has sufficient mechanical strength, but also can be easily disassembled and maintained. During operation, the flexible section can be moderately deformed and adjusted in angle according to the actual working conditions, further enhancing adaptability and use flexibility. For example, during the equipment debugging stage, the technician can appropriately change the posture of the gooseneck pipe 201 as needed to ensure the best working state.

[0048] As shown, Figure 1 In one embodiment, the filter assembly 1 of the automatic vaccine harvesting device for poultry vaccine production of the present application is further configured with a waterproof and breathable film 109. The waterproof and breathable film 109 is installed on the existing structure, ensuring that the internal space remains dry while not hindering air exhaust. This function is achieved through its unique micro-porous structure, which allows water vapor and air molecules to enter while preventing liquid from entering.

[0049] This layer of waterproof and breathable film 109 covers the filter membrane 107 and is installed on the outermost layer of the entire filter assembly 1 and is closely connected with the filter support frame 101, but does not affect the function and positional relationship of the reinforcing plate 103. Its surface is uniformly distributed with a large number of tiny pores, effectively ensuring smooth ventilation and reducing the pressure transmission effect on the surface of the lower filter membrane 107, reducing the influence that may be caused by the external environment or the operation process. In addition, the waterproof and breathable film 109 has excellent waterproofness and breathability, and can maintain stable performance in various environments, ensuring continuous normal operation of the equipment.

[0050] Specifically, the waterproof and breathable film 109 can be firmly attached to the outer surface of the filter assembly 1 by an adhesive. For example, an adhesive with high adhesion and stable chemical properties that does not affect the breathability is selected. In this way, the waterproof and breathable film 109 can be prevented from peeling off easily after a long period of operation, thereby continuously exerting the expected function and meeting the requirements of the production process. This design method not only strengthens the protection measures of the existing equipment, but also greatly improves the overall efficiency of vaccine harvesting.

[0051] As shown in Figure 1 In one embodiment, the design of the vaccine automatic harvesting device for poultry vaccine production of the present application is provided with a special flow stabilizer structure in the vaccine collection body 2. Specifically, the flow stabilizer 202 is installed at the inlet pipe of the mixed solution to ensure smooth flow of the material when entering the vaccine collection body 2. The mixed solution pipe inlet is directly connected to the vaccine collection body 2, and the flow stabilizer 202 is arranged at this position. This design not only optimizes the internal flow dynamic characteristics, but also reduces the pressure burden on the downstream filter assembly 1.

[0052] The presence of the flow stabilizer 202 effectively improves the flow uniformity during feeding, avoiding the adverse effects on the subsequent process steps, especially the sensitive filter device, caused by instantaneous high flow or turbulent flow.

[0053] For example, the target effect can be achieved by setting multi-stage blade or grid flow stabilizer components in the inlet pipe. This structure can make the liquid passing through the flow stabilizer 202 enter the inside of the collection body in a laminar flow state, reducing the impact force of the fluctuation on the system and ensuring more uniform and consistent liquid distribution.

[0054] In actual operation, the vaccine mixed solution is first subjected to preliminary centrifugation or sedimentation treatment and stored in the vaccine collection body 2. Then, the pressure balance valve 3 is used to adjust the pressure difference between the collection body and the filter assembly 1 to maintain a constant liquid flow rate and reduce the instantaneous high pressure on the filter membrane 107. After the mixed solution enters the filter assembly 1, it first contacts the cylindrical rigid frame with a double-layer grid structure. The frame provides support for the filter membrane 107, maintains the shape of the circular concave surface 102, and uses the reinforcing plate 103 on the outside to uniformly distribute the pressure acting on the filter membrane 107, preventing the filter membrane 107 from being damaged or deformed due to pressure concentration. Ring-shaped silica gel buffer pads 104 are provided at the contact between the frame and the filter membrane 107 to protect the edges of the filter membrane 107 and enhance the overall sealing and stability. Finally, the material after precise filtration is discharged through the vaccine collection outlet, and the sealing connector 4 ensures that all connections are tightly leak-proof and can withstand a certain internal and external pressure difference during the entire process.
