Description

Technical Field

[0001] This utility model relates to the field of tank insulation technology, specifically a constant temperature reaction tank for compound bacterial fermentation. Background Technology

[0002] Complex microorganisms refer to symbiotic or synergistic systems composed of two or more microorganisms. Fermentation is the process by which microorganisms convert organic matter into target products, and complex microorganisms require complex microbial fermentation reactors for fermentation.

[0003] Currently, most existing compound microbial fermentation reactors use an insulation cavity between the inner and outer shells to reduce heat transfer to the outside. However, the insulation cavity contains connecting rods for supporting and fixing the inner and outer shells, but does not form a thermal break structure, which makes it easy for heat to transfer and thus affects the stability of the temperature inside the reactor.

[0004] Therefore, we propose a constant-temperature reaction vessel for the fermentation of compound bacteria in order to solve the problems mentioned above. Utility Model Content

However, the insulation cavity contains connecting rods for supporting and fixing the inner shell and the outer shell, but does not form a thermal break structure, which makes it easy for heat to transfer and thus affects the stability of the temperature inside the reactor.

[0011] Furthermore, the feed inlet includes a first inlet and a second inlet, and the discharge inlet includes a third inlet and a fourth inlet. The first inlet and the third inlet are fixed to the inner shell, and the second inlet and the fourth inlet are fixed to the outer shell. The second broken bridge component includes an annular block, on which annular connecting plates are symmetrically arranged. The first inlet, the second inlet, the third inlet, and the fourth inlet are all adapted to the annular connecting plates, and the cross-section of the annular connecting plate is a U-shaped structure. A third filling cavity is opened in the annular block, and a third heat-insulating filler is filled in the third filling cavity.

[0012] Furthermore, the U-shaped connecting plate is provided with a first bolt, and the first rod and the second rod are connected to the U-shaped connecting plate by the first bolt.

[0013] Furthermore, the annular connecting plate is provided with a second bolt, and the first and second pipe openings, as well as the third and fourth pipe openings, are all connected to the annular connecting plate by the second bolt.

The adapter tube includes a fifth port and a sixth port. The fifth port is fixed to the inner shell, and the sixth port is fixed to the outer shell. The fifth and sixth ports are connected to the annular connecting plate by a second bolt. A third ceramic gasket is provided between the fifth and sixth ports and the annular connecting plate. A sealed bearing adapted to the stirring rod is provided on the inner wall of the fifth port.

[0017] The beneficial effects of this utility model are as follows: 1. By providing a second bridge break on the feed inlet, the discharge outlet, and the adapter pipe, the heat conduction on the feed inlet, the discharge outlet, and the adapter pipe can be blocked by the second bridge break.
