Optionally, the filter filler is filter cotton and activated carbon filled in the filter cavity.
Optionally, the temperature control device is a pre-frozen ice row placed in the temperature control cavity.
Optionally, the shrimp frame includes stainless steel's supporting framework, the supporting framework cladding has the netting of 0.5cm square hole, be provided with the door of putting, getting the shrimp that can open and close on the supporting framework.
Optionally, an arc-shaped cavity of 8cm × 8cm × 60cm is respectively arranged at four corners of the top of the central cavity, and the arc-shaped cavity is located between two adjacent hollow jackets; air pumps, digital display dissolved oxygen probes, digital display temperature probes and digital display pH meters are inserted into the four arc-shaped cavities respectively, interfaces of the air pumps are communicated with the nano air stones, the interfaces of the air pumps are connected with the temperature control cavity air holes respectively through two branch pipelines, the air pumps are respectively provided with air quantity regulating valves between the nano air stones and the temperature control cavity air holes, and the digital display dissolved oxygen probes, the digital display temperature probes and the digital display pH meters are all spaced from the bottom 10cm of the central cavity and stretch into the central cavity.
