Description

Technical Field

[0001] This utility model belongs to the technical field of fermentation equipment, specifically relating to a stainless steel pipe adapter plate and a fermentation transfer system. Background Technology

[0002] Traditional fermentation transfer stations require two valves (inlet valve + outlet valve) for each connecting pipe, resulting in a large number of valves:

[0003] 1. High equipment costs (accounting for 15%-30% of total investment);

[0004] 2. Valve seals are prone to aging and require frequent maintenance and repair;

[0005] 3. Valves in dead zones are difficult to sterilize completely, posing a risk of contamination (especially during high-temperature steam sterilization).

[0006] 4. The pipe has many bends, and residual materials can breed bacteria.

[0007] Although the existing adapter uses quick-connect clamps, the branch pipes are fixedly connected. When switching, the unused branch pipes need to be sealed with blind flanges, which is cumbersome and the blind flange interface still has unsanitary corners. Utility Model Content

[0008] The purpose of this utility model is to provide a stainless steel pipe adapter plate with zero valves, zero blind flanges, and quick switching capability, which solves the problems of high valve cost, many sterilization dead zones, and low operating efficiency.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a stainless steel pipe adapter plate, comprising:

[0010] The disk body is provided with a central interface and at least four branch interfaces that are radially distributed around the central interface.

[0011] The adapter structure includes a flexible connector assembly. The central interface and each branch interface are provided with a chuck connector. Both ends of the flexible connector assembly are provided with quick-connect chucks that engage with the chuck connectors on the central interface and the branch interfaces. Both the quick-connect chucks and the flexible connector assembly can be disassembled independently.

[0012] Preferably, the angle between the central interface and the axis of each branch interface is 15°-30°.

[0013] Preferably, the live connector assembly includes a straight live connector, the length of which is ≤200mm and both ends are threaded with live connectors.

[0014] Preferably, the quick-connect chuck includes a bent tube, one end of which is threaded to a union, and the other end of which is provided with a pressure plate. The pressure plate has several evenly distributed movable grooves, and hooks are rotatably connected to the movable grooves via a rotating shaft.

[0015] Preferably, the chuck connector includes an outer tube layer and an inner tube layer. The top of the inner tube layer has a through hole. An annular plug and a spring that elastically connects the annular plug to block the through hole are slidably disposed in the cavity between the outer tube layer and the inner tube layer. A pressure rod that can extend into the cavity is fixed on the inner wall of the bottom opening of the bent tube. After the quick-connect chuck and the chuck connector are mated, the annular plug will avoid the through hole under the pressure of the pressure rod, so that the pipeline is connected. An alignment groove corresponding to the movable groove is opened at the top edge of the outer tube layer. A stop rod for hooking the quick-connect chuck and the chuck connector is fixed in the alignment groove.

[0016] Preferably, a groove is provided on the outer edge of the bottom port of the bent pipe, and an elastic sealing ring that fits the groove and is squeezed to seal is fixed on the outer edge of the top opening of the outer pipe layer.

[0017] Preferably, a flushing port is provided at the bottom of the cavity between the outer tube layer and the inner tube layer.

[0018] A fermentation transfer system includes a stainless steel pipe adapter plate as described above, wherein the central interface is directly connected to the main material pipe, and the branch pipe interfaces are directly connected to independent fermentation tanks via fixed pipes.

[0019] Compared with the prior art, this utility model provides a stainless steel pipe adapter plate and a fermentation transfer system, which has the following advantages:

[0020] 1. This utility model adopts a valve-free and blind-plate-free design, directly connecting the central interface and the target branch interface through a flexible connecting pipe, and the unused branch interface is naturally open without the need for sealing;

[0021] 2. The straight-through flexible pipe, flexible connector and quick-connect chuck used in this utility model can all be disassembled independently, and can be sterilized separately after disassembly to prevent bacterial residue from cross-contaminating contaminated materials during connection.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a stainless steel pipe adapter plate, including a plate body 1 and an adapter structure 4, wherein the plate body 1 is formed by CNC machining of a single piece of 316L stainless steel, and the plate body 1 can be a circle, a semi-circle or a figure-element rectangle. The plate body 1 is provided with a central interface 2 and at least four branch pipe interfaces 3 arranged radially around the central interface 2, and the angle between the central interface 2 and the axis of each branch pipe interface 3 is 15°-30°.

[0032] Please see Figure 3 and Figure 4The adapter structure 4 includes a union pipe assembly 41. The central interface 2 and each branch interface 3 are provided with a chuck connector 43. Both ends of the union pipe assembly 41 are provided with quick-connect chucks 42 that engage with the chuck connectors 43 on the central interface 2 and the branch interface 3. Both the quick-connect chucks 42 and the union pipe assembly 41 can be disassembled independently. The union pipe assembly 41 includes a straight-through union pipe 411. The length of the straight-through union pipe 411 is ≤200mm and both ends are threaded with union connectors 412. The straight-through union pipe 411, union connectors 412 and quick-connect chucks 42 can be disassembled independently, and can be sterilized separately after disassembly to prevent bacterial residue from cross-contaminating contaminated materials during connection.

[0033] Please see Figure 4 and Figure 6 The quick-connect chuck 42 includes a bent tube 421, one end of which is threaded to a union 412. The other end of the bent tube 421 is provided with a pressure plate 423. Several evenly distributed movable grooves 424 are provided on the pressure plate 423. Hooks 426 are rotatably connected to the movable grooves 424 through a rotating shaft 425.

[0034] Please see Figure 4 and Figure 5 The chuck connector 43 includes an outer tube layer 431 and an inner tube layer 432. The top of the inner tube layer 432 is provided with a through hole 433. An annular plug 434 and a spring 435 that elastically connects the annular plug 434 to block the through hole 433 are slidably arranged in the cavity between the outer tube layer 431 and the inner tube layer 432. A pressure rod 422 that can extend into the cavity is fixed on the inner wall of the bottom opening of the bend 421. After the quick-connect chuck 42 and the chuck connector 43 are connected, the annular plug 434 will avoid the through hole 433 under the pressure of the pressure rod 422, so that the pipeline is connected. The top edge of the outer tube layer 431 is provided with an alignment groove 438 corresponding to the movable groove 424. A stop rod 439 is fixed in the alignment groove 438 for the hook 426 to hook and connect the quick-connect chuck 42 and the chuck connector 43.

[0035] Furthermore, a groove 427 is provided on the outer edge of the bottom port of the bend 421, and an elastic sealing ring 437 is fixed on the outer edge of the top opening of the outer tube layer 431 to fit the groove 427 for compression sealing, so as to achieve the sealing after the quick-connect chuck 42 and the chuck connector 43 are connected, and to prevent material leakage during the material transfer process.

[0036] Furthermore, a rinsing port 436 is provided at the bottom of the cavity between the outer tube layer 431 and the inner tube layer 432, which facilitates cleaning of the cavity through the rinsing port 436 and prevents bacteria from growing in the cavity.

[0037] A fermentation transfer system includes a stainless steel pipe adapter plate as described above. The central interface 2 is directly connected to the main material pipe, and the branch pipe interfaces 3 are directly connected to independent fermentation tanks via fixed pipes. Figure 1As shown in the example, the disc body 1 is provided with seven branch pipe interfaces 3 arranged radially with the central interface 2 as the center. When it is necessary to feed material to tank No. 1, the quick-connect chucks 42 at both ends of the live pipe assembly 41 are connected to the chuck connectors 43 on the central interface 2 and the corresponding branch pipe interface 3 of tank No. 1, respectively. The chuck connectors 43 at other interfaces remain in their natural state (because the annular sliding plug 434 seals the through hole, thus sealing the pipeline and preventing material from overflowing).

[0038] The working principle and usage process of this utility model are as follows: When it is necessary to connect the central interface 2 with one of the branch pipe interfaces 3, firstly, the two unions 412 are threaded onto both ends of the straight-through union pipe 411, and then the two bends 421 are threaded onto the two unions 412 respectively. The two bends 421 are respectively aligned with the chuck connectors 43 on the central interface 2 and the branch pipe interface 3 and pressed together. The hooks 426 on the movable groove 424 are rotated to hook the stop bar 439 to achieve docking. The annular sliding plug 434 in the cavity between the outer pipe layer 431 and the inner pipe layer 432 slides downward under the pressure of the pressure bar 422, thereby avoiding the through hole 433 and making the pipeline connected. The mutual compression of the elastic sealing ring 437 and the groove 427 achieves the sealing at the interface, so that the material can be transferred through the central interface 2 and the branch pipe interface 3.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
