Description

Technical Field

[0001] The utility model relates to the technical field of desalination and thickening, in particular to a heat preservation type desalination and thickening mechanism for white - leg shrimp (Litopenaeus vannamei). Background Technique

[0002] White - leg shrimp (Litopenaeus vannamei) is native to the warm - water waters along the Pacific coast of Latin America. It has become one of the world - recognized excellent aquaculture varieties due to its characteristics such as high temperature resistance, low salinity tolerance, fast growth, strong disease resistance, long survival time out of water, and low requirement for protein. During the process of white - leg shrimp aquaculture, desalination and thickening are required. Desalination and thickening are to enable the shrimp larvae to better adapt to the aquaculture environment. During the desalination and thickening process, brine of different concentrations needs to be poured into fresh water for mixing, and a desalination and thickening mixing tank will be used. However, there are two disadvantages in the existing desalination and thickening mixing tanks on the market. First, the existing desalination and thickening mixing tanks cannot heat the mixed water during use, which is not convenient for transferring the mixed water into the desalination and thickening pond. When desalinating and thickening, the water temperature needs to be guaranteed at 20 degrees Celsius. Without being able to heat the mixed water, the water temperature in the desalination and thickening pond cannot be guaranteed, which is not conducive to the normal growth of white - leg shrimp. Second, the existing desalination and thickening mixing tanks cannot keep the mixed water warm during use. Since the desalination and thickening mixing tank needs to be heated, the rapid dissipation of heat after heating is also not conducive to the normal growth of white - leg shrimp. During use, the mixed water also needs to be heated separately, which is not convenient enough. Content of the Utility Model
