Description

Technical Field

[0001] This utility model relates to the field of photobioreactor technology, and in particular to a detachable connection structure for a photobioreactor tube. Background Technology

[0002] A photobioreactor is a device used for the culture of photosynthetic microorganisms and their photosynthetic tissues or cells. This type of reactor has a similar structure to a general bioreactor, and under normal conditions, it requires specific light, temperature, and nutrients to cultivate microorganisms and to regulate and control the system environment. Chinese Patent CN217202716U discloses a tubular photobioreactor with an internal circulation device. Specifically, it discloses that a connecting ring is fixedly connected to the outer surface of the photoreactor tube, and both the connecting ring and the fixing ring have threaded holes on their sides. The inner wall of the threaded holes is threaded with mounting bolts. This patent requires bolts for disassembly and reassembly, which is time-consuming and inefficient. Therefore, there is an urgent need for a detachable connection mechanism for the photobioreactor tube that allows for rapid disassembly and reassembly, improving efficiency. Utility Model Content

[0020] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0021] Please refer to Figures 1 to 3 A detachable connection mechanism for a photobioreactor tube, comprising:

[0022] A fixed plate is attached to a fixed ring on one side. The fixed ring is connected to an upper connecting pipe. A temperature-controlled liquid inlet pipe is coaxially sleeved inside the connecting pipe. The fixed ring has an annular groove with a permanent magnet inside. A photoreaction tube is attached to the side of the fixed ring. A temperature-controlled tube is connected to the inner wall of the photoreaction tube through a connecting column. The radius of the temperature-controlled tube is the same as that of the temperature-controlled liquid inlet pipe.

[0023] A connecting ring is attached to the outer wall of the photoreaction tube, and an iron block matching the permanent magnet is provided on the connecting ring.

[0024] In the above embodiments, when the temperature control tube and the connecting tube are aligned coaxially, the iron block on the connecting ring is connected to the permanent magnet on the fixing ring. The magnetic attraction force automatically locks the connection in place. Compared with the prior art, the magnetic attraction force enables quick disassembly and installation, improving efficiency.

[0025] As an optional implementation, a first circular connecting sleeve is connected to the end of the temperature control tube near the fixing ring. The radius of the first circular sleeve is smaller than that of the photoreaction tube. A first coaxial through hole is provided inside the first circular connecting sleeve, which is connected to the temperature control tube. A rotating shaft is provided inside the first through hole, and the axis of the rotating shaft is Y-shaped. A coaxial torque spring is provided on the rotating shaft, and a circular plate is connected to the torque spring. A second circular connecting sleeve is provided to the end of the temperature control inlet tube near the fixing ring. The radius of the second circular sleeve is smaller than that of the connecting tube. A second coaxial through hole is provided inside the second circular connecting sleeve, which is connected to the temperature control inlet tube. Three limiting posts are provided on the side of the second circular sleeve away from the connecting tube. In the assembled state, the three limiting posts push the circular plate open, and the circular plate opens the first through hole. The three limiting posts are located above the rotating shaft. In the disassembled state, the three limiting posts are away from the circular plate, and the circular plate closes the first through hole.

[0026] In the above embodiments, by setting the first circular sleeve and the second circular sleeve, during assembly, the three limiting posts can push the circular piece open, thereby opening the first through hole and connecting the temperature control tube with the temperature control liquid inlet tube. When disassembling, the three limiting posts move away from the disc, and the circular piece closes the first through hole through the torque spring, preventing the water inside the temperature control tube from flowing out during disassembly.

[0027] As an optional implementation, a sealing ring is provided at one end of the first circular sleeve near the fixing ring.

[0028] In the above embodiments, leakage can be prevented during assembly by setting a sealing ring.

[0029] As an alternative implementation, the permanent magnet is a conical part, and the iron block is a conical iron block.

[0030] In the above embodiments, during assembly, the conical iron block and the conical part cooperate to automatically correct the positional deviation of the iron block when it is inserted by the inclined surface of the conical part. During disassembly, the axial separation force can be partially converted into a radial force by the inclined mechanical effect of the conical surface of the conical part, reducing the operating force required for direct pulling and thus reducing the wear on the permanent magnet.

[0031] As an optional implementation, the distance from the disc to the end of the first through hole near the connecting ring is less than the length of the limiting post.

[0032] In the above embodiments, the disc can be pushed open by the limiting post during assembly.

[0033] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
