Problems solved by technology

But solar energy also has two main disadvantages: one is the low energy flow density; the other is that its intensity cannot be maintained constant due to the influence of various factors (season, location, climate, etc.)
This technology has been widely used in all aspects of production and life, but how to apply solar energy technology to the production process of shellfish seedlings is especially suitable for heating seawater and controlling the seawater in shellfish seedling cultivation ponds conveniently and accurately temperature, in order to facilitate the growth of shellfish seedlings, so far, there is no relevant report at home and abroad

Embodiment Construction

[0017] Such as figure 1 As shown, a specific embodiment of applying the solar seawater heating control device to bivalve seawater seedlings: a set of solar heating equipment is equipped for the seawater nursery, and its main components include a heat collection system, a control system, and a heat exchange system , Auxiliary heating system and shellfish seed cultivation pool, etc. The control system can automatically detect and record the temperature of each main link, and the central controller controls the valves or switches to control the fresh water circulating pump, the flow of seawater and the auxiliary heater.

[0018] The heat collection system includes 8 vacuum tube solar heat collectors with a single area of ​​3m 2 , with a total area of ​​24m 2 .

[0019] The specific functions of its temperature control system are:

[0020] 1. Automatically detect the temperature T1 of solar preheated water, the preheated fresh water temperature T2, T2' in heat storage tank I a...

Abstract

A temp controller for the solar heater used in culturing the larvae of bivalve shellfish has vacuum tube type solar heat collector, heat exchanging system consisting of heat accumulator and coiled Ti-steel tube, central controller, fresh water tube, seawater tube, and circulating pump. There connection scheme is also disclosed.

Description

technical field [0001] The invention belongs to an auxiliary device for bivalve mollusc seedling cultivation technology in aquaculture technology, in particular to a solar seawater temperature rise control device in bivalve mollusk seedling cultivation production. Background technique [0002] Many bivalve molluscs have two peak breeding seasons in spring and autumn, and, through artificial regulation, their breeding cycle can be extended on this basis. But, owing to the limitation of conditions such as energy and funds, at present, my country's shellfish seed cultivation period is mainly in spring and summer when the water temperature is higher in the main breeding period of shellfish in China, and uses filtered natural seawater to carry out seedling cultivation. In order to improve production efficiency and economic benefits in some areas, the method of heating seawater by boiler heating is used to start seedling production earlier in spring. Although this heating method ...
