Seafood temporary-culture water circulation purification system and seafood temporary-culture machine using same

Abstract

The invention discloses a seafood temporary-culture water circulation purification system and a seafood temporary-culture machine using the same. The system comprises culture pools, wherein the plurality of culture pools are arranged in parallel; a water inlet of each culture pool individually communicates with a corresponding refrigeration water tank, the plurality of refrigeration water tanks are arranged in parallel, and the number of the refrigeration water tanks corresponds to the number of the culture pools; and a water outlet of each culture pool individually communicates with a corresponding filtration box, the plurality of filtration boxes are arranged in parallel, and the number of the filtration boxes corresponds to the number of the culture pools. Refrigerants are introduced tothe refrigeration water tanks to cool culture waters, a plurality of cold culture waters in different temperature zones are formed, and low-temperature culture waters are respectively fed into the culture pools for seafood temporary-culture. After temporary-culture, culture waters containing impurities and proteins are sent to the filtration boxes to filter, degrade and remove proteins, and thenthe culture waters are reduced to clean waters to cyclic utilization. Water temperatures of the culture pools are constant and stable, temporary-culture time is long, seafood culture in a plurality ofdifferent temperature zones is realized, numbers of temporary-culture varieties are large, and people consumption requirements are satisfied.

Description

technical field [0001] The invention belongs to water treatment equipment, and in particular relates to a seafood temporary raising water circulation purification system and a seafood temporary raising machine. Background technique [0002] Seafood, also known as seafood, refers to the use of marine animals as delicacies, including fish, shrimp, shellfish and so on. Seafood is a food with high nutritional value, so it is very popular among people, and because seafood is rich in many elements that the human body lacks, people hope to eat fresh seafood. [0003] Seafood needs to go through transportation and storage before being served on the dining table. In order to prolong the survival time, farmers' markets, small seafood restaurants, and supermarkets all need to be equipped with seafood temporary storage equipment, such as: water basins, iron basins, plastic boxes, Foam boxes, cement pools, glass boxes, etc., plus simple equipment such as oxygen generators and filters fo...

AI Technical Summary

Problems solved by technology

There are also manufacturers who have designed seafood low-temperature water tanks, using one refrigerator to supply refrigerant to multiple pools, but the power of a single refrigerator cannot be increased infinitely, the cooling effect is still not ideal, and it is impossible to achieve multi-temperature zone breeding; One refrigerator supplies refrigerant to multiple pools. Although it can basically meet the requirements of low-temperature pools, there is a problem of a large number of equipment in the refrigeration system. The electrical system for temperature control is very complicated, which increases the manufacturing cost and maintains the cost. high

Therefore, it is obviously impossible to achieve the purpose of constant temperature by adopting the refrigeration system of "one drag multiple" or "two drag multiple" refrigerators.

[0006] 2. The existing aquaculture process requires frequent manual water changes to clean up animal excrement and biochemical impurities, which increases labor intensity

Chinese patent document CN204180729U discloses an aquaculture filter box, which includes a turnover box, a culture filter box and a water pump, a spray pipe and a filter cotton are arranged in the culture filter box, and the water pump is connected with an oil removal film pipe; impurities are removed by the spray pipe and filter cotton, The oil removal film tube removes the oil film. This filter structure can physically remove impurities. However, due to the variety of cultured seafood, the biochemical components in the culture water are complex and cannot be removed at all. The culture water is easy to deteriorate in a complex biochemical environment and discharge the pollution of the culture water. surroundings

Because the aeration foam produced by the traditional protein skimmer is carried out under negative pressure, the pipeline connection is quite complicated, the air pressure required for the aeration foam is relatively large, and a large-power air pump is required for normal use; moreover, due to the aeration components The coil structure is adopted, and the air can only be aerated to the outside during aeration, the power of generating bubbles is obviously insufficient, the amount of adsorbed impurities is small, the protein separation effect is poor, and the quality of purified water is difficult to meet the requirements
