Description

Technical Field

[0001] The invention discloses a fresh water automatic recycling device suitable for large ships, which is used for recycling fresh water when fresh water is insufficient on large ships sailing at sea, and relates to the technical field of design of equipment and layout for fresh water reuse on large ships. Background Art

[0002] All kinds of ships sailing on rivers, lakes and seas need fresh water. This is easier to solve for ships sailing on inland rivers. In the relatively clean sections of the river, water is pumped up by pumps. Some ships also obtain water by connecting to water pipes at ports. However, it is not so simple for ships sailing on the sea, especially for ocean-going ships sailing in the vast ocean. A voyage takes a long time, and the lives of people on board are inseparable from fresh water. Crew members and passengers on board need to take a bath, wash clothes, cook, drink, and use hygiene and flush toilets every day, which all require a large amount of fresh water. The operation of machines also requires a large amount of fresh water. In the prior art, in order to solve the problem of fresh water shortage, when encountering a shortage of fresh water, the ship will think of various ways to solve it, such as collecting air-conditioning condensate for use after going to the toilet. , use buckets of sea water to flush the toilet. When it rains heavily, the crew will take a natural bath on the deck, or use a seawater pump to pump seawater for a seawater bath. After taking a seawater bath, the wind will make the whole body full of salt, which is very uncomfortable. Therefore, after taking a seawater bath, the crew will go back to the room and rinse again with a small amount of fresh water. Is it possible to store more fresh water before departure? This is also not feasible. First of all, if the water storage tank is too large, less cargo will be loaded. Moreover, if the fresh water is stored for a long time, the water will deteriorate and cannot be used. Therefore, in the past, large ships sailing on the sea, if they encounter water shortages, even ballast water will be used for life;

[0003] Large ships manufactured nowadays are basically equipped with "water makers", that is, seawater desalination devices. In layman's terms, the seawater is "boiled" and the resulting steam is condensed into distilled water and collected to become fresh water. This is not only very costly, but also requires a large area for seawater desalination devices, which is not economical. Even large ships now strictly control the use of fresh water in order to meet the fresh water needs for long-term voyages at sea. Fresh water is generally divided into two types: one is fresh water for cooking and drinking, which is very precious and is brought from the ship's water tanks; the other is domestic water, which is used for washing clothes and taking a bath. This fresh water is desalinated from seawater. In the prior art, only luxury cruise ships are equipped with water makers that produce a large amount of water per day to meet the needs of passengers and crew members. The layout of the water makers and the complex piping system are much stricter than those of merchant ships. Utility Model Content

The turbid water settling tank 32 is fixed by the water tank bracket 33. The turbid water flowing into the turbid water settling tank 32 of the bottom cabin, after the turbid water in the turbid water settling tank 32 is precipitated, the surface water is discharged into the filter tank 28 through the turbid water discharge pipe filter 30 and the turbid water discharge pipe 29 in turn. In the filter tank 28, the inflowing water will pass through the filter screen 26 on the top of the tank, and then pass through the filter tank sand and gravel filter layer 27 downward, and then pass through a clean water discharge pipe filter screen 25 again, and then enter the clean water storage tank 23 through the clean water discharge pipe 24; when the clean water tank 7 arranged on the upper layer is After the water level sensor senses the water level drop, the information is transmitted to the electric control box 16, which starts the water supply pump to pump the clean water in the clean water storage tank into the clean water tank 7 through the clean water supply pipe for standby;
