Embodiment 1

[0017] See Figure 1-2 , a cooling device for sea cucumber culture ponds, including a box 1, the box 1 is made of container cold storage, the bottom wall of the inner cavity of the box 1 is provided with a bottom plate 2, the bottom plate 2 is Made of stainless steel, the bottom plate 2 is inclined, the angle α between the bottom plate 2 and the bottom wall of the inner cavity of the box body 1 is 1°-3°, and one side of the box body 1 is connected to the air intake hole 5, the other side end of the box body 1 is connected to the air outlet hole 4, the outer end of the air inlet hole 5 is connected to the blower 6, and the distance between the air outlet hole 4 and the bottom wall of the box body 1 is 10cm-20cm , the top of the bottom plate 2 is provided with a vent pipe 3, the vent pipe 3 is a heat exchange tube, the vent pipe 3 is a serpentine structure, the diameter of the vent pipe 3 is 10cm, and the thickness of one side of the vent pipe 3 is 1mm, which is relatively The ...

Embodiment 2

[0019] The difference from Example 1 is that: the end of the box body 1 close to the air outlet 4 is connected with a water outlet 9 matched with the ice layer 8, the water outlet 9 is higher than the air outlet 4, and the air passes through the ventilation pipe 3 The heat exchanged into the ice cube layer 8 makes the ice cube layer 8 melt gradually, and the ice water produced by melting is discharged through the water outlet hole 9, and the ice water is discharged through the water outlet hole 9, which can effectively prevent the accumulation of ice water in the box body 1 , thereby ensuring the heat exchange cooling effect of the ice layer 8 on the air, and ensuring the cooling quality of the pond.

[0020] The height of described fence 7 is 10cm, and fence 7 comprises some steel pipes, and all described steel pipes are arranged side by side in parallel, utilizes fence 7 to cooperate base plate 2 to limit ice cube layer 8, thereby guarantees that ice cube layer 8 passes air p...

Abstract

The invention discloses a cooling and refrigerating device for a stichopus japonicus aquaculture pond. The cooling and refrigerating device comprises a tank body, wherein a bottom plate is arranged onthe bottom wall of the cavity of the tank body; an air inlet is connected with one side end of the tank body in a running through manner, and an air outlet is connected with the other side end of thetank body in a running through manner; and a blower is connected with the outer end of a vent pipe in a running through manner, and an ice cube layer is arranged at the top end of the bottom plate. According to the cooling and refrigerating device, air is pumped into the vent pipe through the blower with the air inlet, and performs heat exchange with the ice cube layer through the vent pipe, so that the air is cooled, low-temperature air is exhausted out from the air outlet, and water in the aquaculture pond can be cooled; and the whole cooling process can realize quick and sufficient water cooling by inflating cold air into water for cooling, and the high-temperature defense performance of stichopus japonicus in summer can be promoted; and a great number of air is injected to the pond tofavor increasing the dissolved oxygen of pond water and improving the growing environment of the stichopus japonicus.

Description

technical field [0001] The invention relates to the technical field of sea cucumber pond cultivation, in particular to a cooling device for sea cucumber cultivation ponds. Background technique [0002] Sea cucumber, also known as imitation sea cucumber, has developed into an important aquaculture species in my country's mariculture industry after 20 years of continuous development. The coasts of Shandong Province and Liaoning Province are the main production areas of sea cucumbers in my country, which can realize the year-round cultivation of sea cucumbers; Fujian Province mainly raises ginseng from the north and south in winter, and its output is also relatively large. In 2018, my country's sea cucumber farming area was 238,100 hectares and the output reached 174,300 tons. There is a large area of ​​pond culture in sea cucumber cultivation, among which the sea cucumber cultivation area in the Yellow Sea Delta region exceeds 400,000 mu, but the water temperature in this are...
