Description

TECHNICAL FIELD

[0001] The utility model relates to filter technical field, concretely relates to a double sea water filter. BACKGROUND

[0002] In the process of ship operation, the seawater system plays a vital role, such as providing water source for the cooling system, fire fighting system and the like of the ship. However, the seawater contains a large amount of impurities and particulate matters, such as shellfish, seaweed, silt and the like, if not effectively filtered, these impurities will enter various systems of the ship, resulting in equipment wear and tear, blockage, affecting the normal operation of the ship, and even causing safety accidents.

[0003] In the early days, the ship ballast seawater system mostly adopts single sea water filter system. However, the single sea water filter has obvious limitations, and the seawater filtration system needs to be cleaned regularly with the change of sailing time and sea area impurity condition. When cleaning the seawater filter, the valves before and after the filter need to be cut off, which means that the seawater system must be stopped, which will generally affect the ship operation time.

[0004] For example, when the cooling system of the ship needs to be cleaned due to filter blockage, if single sea water filter is used, the operation of the cooling system must be suspended, which may cause the equipment temperature to be too high, affecting the performance and service life of the equipment. Moreover, once the single sea water filter is blocked by shellfish and seaweed in seawater, seawater cannot enter the required seawater cooling and fire fighting system, and the consequences are unpredictable.

[0005] In order to solve the above problems of single sea water filter, a double sea water filter which is easy to disassemble and clean is needed to be developed, which can operate simply to clean or maintain one of the filters without stopping the seawater system, ensuring the continuous operation of the ship seawater system, improving the reliability and safety of the ship.

DETAILED DESCRIPTION

[0033] The utility model is further illustrated below in combination with the accompanying Figure 1 , 2 , 3, 4, 5 and examples 1, 2.

[0034] Example 1

[0035] As shown in Figure 1 , 2 , 3, 4, 5, the double seawater filter of the utility model comprises a filter tank 1, a connecting pipe body 2, a valve 3 and a handle 4.

[0036] The filter tank 1 comprises a first filter tank 11 and a second filter tank 12, and the first filter tank 11 and the second filter tank 12 are arranged side by side. The first filter tank 11 and the second filter tank 12 have basically the same structure and function, and the two filter tanks can work simultaneously or alternately to meet the demand of a ship for clean seawater.

[0037] The connecting pipe body 2 is arranged between the upper part of the first filter tank 11 and the upper part of the second filter tank 12 and is connected to the first filter tank 11 and the second filter tank 12 respectively. A first filter tank water inlet 111 is arranged at the bottom of the first filter tank 11, a second filter tank water inlet 121 is arranged at the bottom of the second filter tank 12, and a first water outlet 21 and a second water outlet 22 are arranged at the bottom of the connecting pipe body 2 respectively, corresponding to the water outlets of the first filter tank 11 and the second filter tank 12. The connecting pipe body 2 connects the filter tank with other components, so that seawater can flow between different components.

[0038] The valve 3 is arranged in the connecting pipe body 2, and the different filter cans can be switched by the valve 3.

[0039] The handle 4 is arranged on one side of the connecting pipe body 2 and is connected with the valve 3. The filter cans can be switched by operating the handle 4. Meanwhile, the filter cans used at present can be directly judged by observing the position of the handle 4, so that the operator can operate and manage conveniently.

[0040] Further, the first filter can drain port 112 is arranged on one side of the bottom of the first filter can 11, and the second filter can drain port 122 is arranged on one side of the bottom of the second filter can 12. The drain ports are opened to drain water or prevent freezing when needed. When the ship is parked in a cold area, the filter cans are prevented from being damaged due to ice expansion by opening the drain ports to drain the seawater and prevent freezing; when the filter cans need to be cleaned and maintained, the drain ports can also be opened to drain the sewage in the cans.

[0041] Further, the first filter can openable cover 113 is arranged on the top of the first filter can 11, and the second filter can openable cover 123 is arranged on the top of the second filter can 12. The first filter can 11 and the second filter can 12 can be quickly opened through the openable covers, so that the filter core or the filter screen inside can be regularly cleaned or replaced.

[0042] The working process of the double seawater filter is as follows:

[0043] The water inlet stage: the seawater enters the first filter can 11 and the second filter can 12 through the first filter can inlet 111 and the second filter can inlet 121 respectively. The two filter cans can work simultaneously or alternately to meet the demand of the ship for clean seawater. For example, when the ship is normally running, the two filter cans can work simultaneously to improve the filtering efficiency; when one of the filter cans needs to be cleaned or maintained, the other filter can work alone to ensure the supply of seawater.

[0044] The filtering stage: the seawater entering the filter cans is filtered by the filter core or the filter screen inside the filter cans, the impurities and particulate matters are intercepted on the surface of the filter core or the filter screen, and the clean seawater enters the upper space of the filter cans through the filter core or the filter screen.

[0045] The water outlet stage: the filtered seawater flows out through the first water outlet 21 and the second water outlet 22 at the bottom of the connecting pipe body 2, the valve 3 is arranged in the connecting pipe body 2, and the valve 3 can be controlled by operating the handle 4, so that the filtering operation of different filter cans can be switched.

[0046] The maintenance stage:

[0047] Drainage: when the filter tank needs to be cleaned and maintained or the ship is parked in a cold area, the first filter tank drain 112 and the second filter tank drain 122 can be opened to drain the seawater or sewage in the filter tank.

[0048] Cleaning or replacement: by rotating the first filter tank openable cover 113 and the second filter tank openable cover 123, the filter tank can be quickly opened, and the filter core or filter screen inside can be cleaned or replaced to ensure the filtering effect of the filter tank.

[0049] Embodiment 2

[0050] Based on the above structural basis of embodiment 1, as shown in Figure 1 、 2 , 3, 4, 5.

[0051] The double seawater filter, the first filter tank openable cover 113 and the second filter tank openable cover 123 are both rotary openable covers. Compared with other opening methods, the rotary design is more convenient and fast to operate, can save the time and effort of the operator, and improve the maintenance efficiency.

[0052] Further, the valve 3 is a stop ball valve, which has the advantages of good sealing, simple operation, precise flow control, and strong durability.

[0053] Further, the material of the double seawater filter is brass. The double seawater filter made of brass can resist corrosion of seawater, prolong the service life of the equipment, and reduce the maintenance cost.

[0054] In summary, the double seawater filter is easy to disassemble and clean, and one of the filters can be easily cleaned or maintained without stopping the seawater system, which ensures the continuous operation of the ship seawater system and improves the reliability and safety of the ship.

[0055] The above is only the preferred embodiment of the utility model, and it should be noted that for ordinary skilled persons in the technical field, several improvements can be made without departing from the principles of the utility model, and these improvements should also be considered as the protection range of the utility model.
