[0001] This utility model relates to the field of seawater filters, specifically a marine seawater filter. Background Technology

[0002] In the field of shipbuilding and marine engineering, seawater is an important working medium for ship systems. However, seawater often contains various impurities, such as suspended solids, seaweed, and marine debris like plastic bags. If these impurities enter the ship system, they can seriously affect the equipment.

[0003] Existing marine seawater filters are prone to clogging when exposed to seawater impurities, causing them to malfunction and affecting their filtration efficiency. Utility Model Content

[0004] To overcome the above-mentioned shortcomings, this utility model provides a marine seawater filter.

[0005] The technical solution adopted by this utility model is as follows:

[0006] A marine seawater filter includes a crushing barrel, with a filter barrel 1 and a filter barrel 2 arranged sequentially on the right side of the crushing barrel. A coarse filter box is fixedly connected to the outer right side of the crushing barrel. Evenly distributed filter holes are formed at the connection between the coarse filter box and the crushing barrel. A crushing mechanism is installed inside the crushing barrel. A drain pipe is fixedly connected to the bottom left side of the crushing barrel, and a discharge valve is installed on the drain pipe. A water pump 1 is located on the left side of the crushing barrel. A water inlet pipe is fixedly connected between the outlet of the water pump 1 and the top left side of the crushing barrel. Filter elements are installed inside both filter barrel 1 and filter barrel 2. A water pump 2 is located on the left side of filter barrel 1, and the inlet of the water pump 2 is fixedly connected to... One end of the first water pump is connected to the water supply pipe, and the other end of the first water pump passes through the top of the coarse filter box and extends to the bottom of the inner side of the coarse filter box. The outlet end of the second water pump is fixedly connected to one end of the first water supply pipe, and the other end of the first water supply pipe is fixedly connected to the top of the first filter box. The left side of the second filter box has a third water pump, the inlet end of the third water pump is fixedly connected to one end of the second water pump, and the other end of the second water pump is fixedly connected to the bottom right side of the first filter box. The outlet end of the third water pump is fixedly connected to one end of the second water supply pipe, and the other end of the second water supply pipe is fixedly connected to the top of the second filter box. The bottom right side of the second filter box is fixedly connected to the outlet valve.

[0007] The crushing mechanism includes a motor, which is fixedly installed on the top of the crushing barrel. Inside the crushing barrel is a rotating shaft, the top and bottom of which are rotatably connected to the middle of the inner top and bottom walls of the crushing barrel, respectively. The top of the rotating shaft extends through the top of the crushing barrel. The bottom of the motor's output shaft is fixedly connected to the top of the rotating shaft. Crushing blades are fixedly connected to the outer wall of the rotating shaft. The crushing blades are evenly distributed around the outer wall of the rotating shaft. There are scrapers on the outer side of the crushing blades. The outer wall of the scrapers slides against the inner wall of the crushing barrel.

[0010] The beneficial effects of this utility model are:

[0011] This invention employs a multi-stage filtration method. First, the seaweed and impurities in the seawater are crushed by a crushing mechanism. Then, the seaweed and impurities are coarsely filtered through filter holes. Finally, the seaweed and impurities are finely filtered through filter elements in filter barrel one and filter barrel two. This effectively removes various impurities from the seawater, including larger seaweed, fragments, and fine particles, thus achieving excellent seawater filtration results.

[0012] The scraper in the crushing mechanism can continuously scrape off the seaweed and impurities attached to the inner wall of the crushing barrel during the crushing process, avoiding the accumulation of impurities on the inner wall of the crushing barrel and causing blockage, thus ensuring the smooth progress of the crushing and coarse filtration process.

Detailed Implementation

[0017] like Figure 1-3As shown: A marine seawater filter includes a crushing barrel 1, with a filter barrel 3 and a filter barrel 4 arranged sequentially on the right side of the crushing barrel 1. A coarse filter box 2 is fixedly connected to the right side of the outer wall of the crushing barrel 1. Evenly distributed filter holes 9 are formed at the connection between the coarse filter box 2 and the crushing barrel 1. A crushing mechanism is installed inside the crushing barrel 1. A drain pipe 10 is fixedly connected to the bottom left side of the outer wall of the crushing barrel 1, and a discharge valve 11 is installed on the drain pipe 10. A water pump 12 is located on the left side of the crushing barrel 1. A water inlet pipe 13 is fixedly connected between the outlet of the water pump 12 and the top left side of the crushing barrel 1. Filter elements 17 are installed inside both the filter barrel 3 and the filter barrel 4, arranged vertically. A water pump 2 14 is located on the left side of the filter barrel 3. The inlet end of the filter is fixedly connected to one end of the pumping pipe 15. The other end of the pumping pipe 15 passes through the top of the coarse filter box 2 and extends to the bottom of the inner side of the coarse filter box 2. The outlet end of the pump 2 14 is fixedly connected to one end of the water supply pipe 16. The other end of the water supply pipe 16 is fixedly connected to the top of the filter bucket 3. The left side of the filter bucket 2 4 has a pump 3 18. The inlet end of the pump 3 18 is fixedly connected to one end of the pumping pipe 2 19. The other end of the pumping pipe 2 19 is fixedly connected to the bottom right side of the filter bucket 3. The outlet end of the pump 3 18 is fixedly connected to one end of the water supply pipe 2 20. The other end of the water supply pipe 2 20 is fixedly connected to the top of the filter bucket 2 4. The bottom right side of the filter bucket 2 4 is fixedly connected to the outlet valve 21.

[0018] The crushing mechanism includes a motor 5, which is fixedly installed on the top of the crushing barrel 1. The crushing barrel 1 has a rotating shaft 6 inside. The top and bottom ends of the rotating shaft 6 are rotatably connected to the middle of the inner top wall and inner bottom wall of the crushing barrel 1, respectively. The top end of the rotating shaft 6 extends through the top of the crushing barrel 1. The bottom end of the output shaft of the motor 5 is fixedly connected to the top end of the rotating shaft 6. The crushing blades 7 are fixedly connected to the outer wall of the rotating shaft 6. The crushing blades 7 are evenly distributed around the outer wall of the rotating shaft 6. The outer side of the crushing blades 7 has scrapers 8. The outer wall of the scrapers 8 slides in contact with the inner wall of the crushing barrel 1. The top and bottom ends of the scrapers 8 extend toward the rotating shaft 6 and are fixedly connected to the rotating shaft 6.

[0019] The tops of crushing barrel 1, filter barrel 3, and filter barrel 4 are all fixedly connected to vent pipe 22.

[0020] The bottom of water pump 12, water pump 24 and water pump 318 are all equipped with support frame 23, and water pump 12, water pump 24 and water pump 318 are installed on the top of support frame 23.

[0021] Water pump 12 starts to draw seawater from the outside and transport the seawater to the crushing barrel 1 through the inlet pipe 13.

[0022] The crushing mechanism inside the crushing barrel 1 starts working. The motor 5 drives the rotating shaft 6 to rotate, which in turn drives the crushing blades 7, which are evenly distributed around the outer wall of the rotating shaft 6, to rotate. The crushing blades 7 quickly crush the seaweed and impurities in the seawater that enters the crushing barrel 1.

[0023] Meanwhile, the scraper 8 on the outside of the crushing blade 7 rotates together with the rotating shaft 6. The outer wall of the scraper 8 slides against the inner wall of the crushing barrel 1. During the crushing process, the scraper 8 can scrape off the seaweed and impurities attached to the inner wall of the crushing barrel 1 to prevent blockage.

[0024] The crushed seawater mixture is in the crushing tank 1. Some of the solid impurities are separated into solid and liquid through the evenly distributed filter holes 9 at the connection between the crushing tank 1 and the coarse filter box 2, thus achieving coarse filtration. The coarsely filtered seawater remains in the coarse filter box 2.

[0025] Water pump 214 starts and draws coarsely filtered seawater from the bottom inside of coarse filter box 2 through water pumping pipe 15. The drawn seawater is then transported to filter bucket 3 through water delivery pipe 16.

[0026] Two filter elements 17 are installed vertically inside the filter barrel 3. Seawater undergoes primary fine filtration through the filter elements 17 to further remove fine impurities from the seawater.

[0027] Water pump 318 starts and draws seawater that has undergone primary fine filtration from the bottom right side of filter tank 3 through water pumping pipe 219. The drawn seawater is then transported to filter tank 24 through water delivery pipe 220.

[0028] Two filter elements 17 are also installed vertically inside the filter barrel 24. Seawater undergoes secondary fine filtration through the filter elements 17 again, so that the seawater is purified more thoroughly.

[0029] After undergoing two-stage fine filtration, the seawater is discharged from the bottom right side of filter tank 4 through outlet valve 21. At this point, the seawater has undergone crushing, coarse filtration, and two-stage fine filtration, resulting in a significant improvement in water quality.

[0030] During the crushing and filtration process, solid impurities accumulated in the crushing barrel 1 can be discharged through the drain pipe 10, and the discharge process is controlled by opening the discharge valve 11.

[0031] The filter element 17 inside filter barrel 3 and filter barrel 4 is the filter material. Different filter elements 17 with different filtration effects can be selected from filter barrel 3 and filter barrel 4. The filter element 17 is a prior art device.
