Technical Field

[0002] In conventional designs, the melting of ice in seawater tanks needs to be achieved by mixing compressed air and steam and injecting them into the seawater tank. To achieve a good effect, the mixed pipeline needs to be facing the seawater tank grille. In the already narrow seawater tank, the layout of the pipeline leads to insufficient space. In this case, when divers clean the seawater tank, they are easily stuck inside due to insufficient internal space, which poses a certain safety hazard. In addition, since steam and compressed air are required, energy consumption is relatively large and the pipeline layout is also relatively complicated. Utility Model Content

[0003] To this end, the technical problem to be solved by the utility model is to overcome the problems existing in the ice melting treatment of the seawater tank in the prior art, and to provide an ice melting system for the seawater tank, which utilizes the temperature of the seawater itself to melt the ice, and has a simple pipeline layout and low energy consumption. At the same time, it can also eliminate safety hazards, and ultimately achieve the effect of ice melting.

[0004] In order to solve the above technical problems, the utility model provides an ice melting system for a seawater tank, comprising:

[0005] A seawater tank having a water inlet and a water outlet;

[0006] A seawater pump is connected to the water outlet of the seawater tank, and the seawater pump draws seawater from the seawater tank;

[0007] A central cooler is connected to the seawater pump, the seawater pump delivers the extracted seawater to the central cooler, and the central cooler can heat the seawater;

The valve body has an inlet end and three outlet ends. The inlet end is connected to the central cooler and the seawater pump, and the three outlet ends are respectively connected to the water inlet of the seawater tank, the water inlet of the seawater pump, and the outboard pipeline.

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0024] Reference Figure 1 As shown, the utility model discloses an ice melting system for a seawater tank, which utilizes the temperature of the seawater itself to melt ice, and has a simple pipeline layout and low energy consumption. It can also eliminate potential safety hazards and ultimately achieve the effect of ice melting.

[0025] In order to solve the above technical problems, the utility model provides an ice melting system for a seawater tank, comprising: a seawater tank 1, a central cooler 2, a seawater pump 3 and a three-way temperature control valve 4, wherein: the seawater tank 1, the central cooler 2, and the seawater pump 3 all have a water inlet and a water outlet, the seawater pump 3 is arranged between the seawater tank 1 and the central cooler 2, the water inlet of the seawater pump 3 is connected to the water outlet of the seawater tank 1, the seawater pump 3 extracts seawater from the seawater tank 1, and the water outlet of the seawater pump 3 is connected to the water inlet of the central cooler 2. The three-way temperature control valve 4 comprises a valve body and a temperature probe, and the temperature probe is arranged at the water outlet of the seawater pump 3, and can detect the temperature of the seawater extracted by the seawater pump 3. The valve body has an inlet end and three outlet ends, and the inlet end is connected with the central cooler 2 and the water outlet of the seawater pump 3, and the three outlet ends are respectively connected with the water inlet of the seawater tank 1, the water inlet of the seawater pump 3, and the outboard pipeline.

[0026] When using the ice melting system of the present embodiment, the temperature of the seawater drawn from the seawater tank 1 is first detected by the three-way temperature control valve 4. When the temperature of the seawater in the seawater tank 1 is detected to be low, the central cooler 2 is used to heat it. For example, the set heating temperature is 20°C, and the temperature of the seawater drawn from the seawater tank 1 detected by the three-way temperature control valve 4 is 16°C. At this time, the seawater is introduced into the central cooler 2 to heat it, and the heated seawater is introduced into the seawater tank 1 to melt the ice of the seawater tank 1, or the heated seawater is introduced into the seawater pump 3 again, and the seawater is continuously heated before being introduced into the seawater tank 1 for melting the ice, thereby finally achieving the effect of melting ice. When the temperature of the seawater in the seawater tank 1 is detected to be high, it is proved that the seawater tank 1 does not need to melt ice. For example, the set heating temperature is 20°C, and the temperature of the seawater drawn from the seawater tank 1 detected by the three-way temperature control valve 4 is 24°C, indicating that the temperature of the seawater entering the central cooler 2 is already very high. At this time, it is indirectly indicated that there is no possibility of freezing in the seawater tank 1, and the seawater is directly discharged out of the hull.

[0027] The ice melting system of the utility model substantially utilizes the temperature of the seawater itself to melt ice, and the pipeline layout is simple. The temperature of the seawater in the seawater tank 1 is first determined, and the seawater that needs to be heated is sent to the central cooler 2 to finally achieve the effect of melting ice. The seawater that does not need to be heated is directly discharged to the outside of the ship without passing through the central cooler 2, which can save energy and reduce safety hazards.

[0028] Specifically, the water outlet of the seawater tank 1 is provided with a remote-controlled butterfly valve 9. Since the seawater tank 1 is arranged outside the hull, it is inconvenient to manually control the switch of the seawater tank 1. Therefore, the remote-controlled butterfly valve 9 is provided to remotely control the water outlet of the seawater tank 1.

[0029] Specifically, a filter 6 is provided on the pipeline between the seawater tank 1 and the seawater pump 3, and the filter 6 can filter the impurities in the seawater tank 1. A manual butterfly valve 5 is provided on the pipeline behind the filter 6, and the pipeline can be controlled to be on and off by the manual butterfly valve 5. When the manual butterfly valve 5 is closed, the filter 6 can be inspected and maintained.

[0030] Specifically, manual butterfly valves 5 are provided on the front and rear pipelines connected to the seawater pump 3. The manual butterfly valves 5 can control the on and off of the pipelines. When the manual butterfly valves 5 are closed, the seawater pump 3 can be inspected and repaired. A butterfly check valve 8 is also provided on the pipeline behind the seawater pump 3 to prevent seawater from flowing back.

[0031] In one embodiment of the utility model, manual butterfly valves 5 are provided on the front and rear pipelines connected to the central cooler 2. The manual butterfly valves 5 can control the on and off of the pipelines. When the manual butterfly valves 5 are closed, the central cooler 2 can be inspected and maintained.

[0032] In one embodiment of the utility model, a plurality of central coolers 2 are arranged between the seawater pump 3 and the three-way temperature control valve 4. The plurality of central coolers 2 can improve the heating efficiency of seawater on the one hand, and on the other hand, when one central cooler 2 is being repaired, another central cooler 2 can be used to heat the seawater.

[0033] In one embodiment of the utility model, a manual butterfly valve 5 is provided on the pipeline between the seawater pump 3 and the three-way temperature control valve 4. The manual butterfly valve 5 can control the on-off of the pipeline. When the manual butterfly valve 5 is closed, the three-way temperature control valve 4 can be inspected and maintained.

[0034] In one embodiment of the utility model, the three-way temperature control valve 4 is connected to the outboard pipeline and connected to the hull outer plate. The outlet height of the outboard pipeline is lower than the ballast water line. A manual butterfly valve 5 and a butterfly check valve 8 are provided on the outboard pipeline. When there is no need to drain water to the outboard pipeline, the manual butterfly valve 5 can be closed. The butterfly check valve 8 is provided to prevent seawater from flowing back.

[0035] Specifically, a stop check valve 7 is provided on the pipeline between the three-way temperature control valve 4 and the seawater tank 1. Similarly, a stop check valve 7 is also provided on the pipeline between the three-way temperature control valve 4 and the seawater pump 3. The stop check valve 7 is provided to control the closing of the pipeline. When seawater circulation is not required, the above two check valves are closed and seawater will be discharged from the outboard pipeline.

[0036] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
