Problems solved by technology

Freshwater ice is the main method for icing operations, and its cost is high. The freezing temperature is much higher than -7° of seawater ice, and it is easy to cause offshore pollution.
Ordinary ice machines cannot meet the requirements of low-temperature continuous flake ice, and special seawater ice-making equipment is required.

Embodiment Construction

[0036] The present invention will be further described below in conjunction with drawings and embodiments.

[0037] Such as figure 1 and figure 2 The marine seawater ice-making equipment shown includes a compressor 1, a condenser 2, an ice-making cylinder 3, a driving device 4 and a control system 5; the ice-making cylinder includes an ice-making shaft 6 and an outer cylinder 7, and the ice-making shaft and the outer cylinder There is a gap for water in between. The inside of the outer cylinder is a hollow structure for circulating refrigerant. The ice-making shaft is engraved with threads, and the thread depth gradually becomes shallower from bottom to top. The driving device is connected to the ice-making shaft; the compressor is connected to the condenser. The condenser is connected to the outer cylinder of the ice-making cylinder through the expansion valve 8, and the outer cylinder is connected to the compressor; the driving device is provided with a torque sensor, and ...

Abstract

The invention discloses marine seawater ice-making equipment. The marine seawater ice-making equipment comprises a compressor, a condenser, an ice-making barrel, a driving device and a control system, wherein the ice-making barrel comprises an ice-making shaft and an outer barrel; a gap is formed between the ice-making shaft and the outer barrel and water can flow into the gap; the outer barrel is internally provided with a hollow structure for circulating a refrigerant, a thread is carved on the ice-making shaft and gradually shallows from bottom to top, and the driving device is connected with the ice-making shaft; the compressor is connected with the condenser, the condenser is connected with the outer barrel of the ice-making barrel through an expansion valve, and the outer barrel is connected with the compressor. The invention also discloses an ice-making method of the marine seawater ice-making equipment. The marine seawater ice-making equipment provided by the invention has the advantages of being ingenious in structure, and being controlled in an intelligent manner.

Description

technical field [0001] The invention relates to the technical field of refrigeration for fishing boats at sea, in particular to marine seawater ice-making equipment and an ice-making method thereof. Background technique [0002] Fishing boats at sea generally spend a long time at sea. After fishing, fishing boats need to keep the catch fresh. At present, most fishing boats at sea use the method of bringing ice into the sea, and a few use quick freezing to keep fresh. Freshwater ice is mainly used for ice-bearing operations, and its cost is high. The freezing temperature is much higher than -7° of seawater ice, and it is easy to cause offshore pollution. Ordinary ice machines cannot meet the low-temperature continuous production of flake ice, and special seawater ice-making equipment is required. Contents of the invention [0003] In order to overcome the shortcomings of the prior art above, the present invention provides a marine seawater ice-making equipment with ingenio...
