[0002] A suction seawater filter is a filtration device used in seawater or liquid systems. It is mainly used to prevent impurities, particulate matter, or organisms from entering pumps, pipes, or other equipment, thereby protecting the system from blockage or damage.

[0003] For existing equipment, a filter canister is usually fixedly installed inside an outer casing. However, when seawater enters the device, long-term use may cause corrosion of the inner wall of the casing, reducing the service life of the device. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this application is to provide a novel anti-corrosion suction-type seawater filter, which solves the problem that long-term use of seawater entering the device may cause corrosion of the inner wall of the device's outer shell, reducing the device's service life.

[0005] The above-mentioned objective of this application is achieved through the following technical solution: a novel anti-corrosion suction seawater filter, comprising a shell and a filter barrel, wherein the side of the shell is provided with an inlet branch pipe and an outlet branch pipe, which are symmetrical to each other, the filter barrel is disposed inside the shell, the inner wall of the shell is fixedly installed with an anti-corrosion protective layer, the bottom surface of the filter barrel is provided with a support component for supporting the filter barrel, and the top surface of the shell is provided with a fixing component for fixedly connecting with the filter barrel.

[0006] Furthermore, two support components are provided and symmetrically distributed on the bottom surface of the filter barrel. The support components include a pad and an L-shaped support plate. The L-shaped support plate is fixedly installed on the bottom surface of the filter barrel, and the pad is fixedly installed on the bottom surface of the L-shaped support plate. The bottom surface of the pad abuts against the bottom surface inside the outer shell.

[0007] Furthermore, a reinforcing plate is fixedly connected to the side of the L-shaped support plate near the pad, and the side of the reinforcing plate away from the pad abuts against the bottom surface of the filter barrel.

[0008] Furthermore, two fixing blocks are fixedly installed on the outer wall of the outer shell, and they are symmetrical to each other. An annular fixing plate is fixedly installed on the top surface of the filter barrel. The top surface of the annular fixing plate has connecting holes, and they are symmetrical to each other. The fixing components include a cover plate and screws. The top of the filter barrel is fixedly connected to the bottom surface of the cover plate. Two screws are provided. The top surface of the cover plate has two through holes, and they are symmetrical to each other. The top surfaces of the two fixing blocks are respectively provided with threaded holes. The two screws are respectively connected to the two through holes on the cover plate and the two connecting holes on the annular fixing plate, and are respectively threaded to the threaded holes on the two fixing blocks. The annular fixing plate is located between the cover plate and the outer shell.

[0009] Furthermore, the outer wall of the filter barrel is provided with an arc-shaped opening, and an inlet guide pipe is fixedly connected to the arc-shaped opening of the filter barrel. One end of the inlet guide pipe is connected to the inlet branch pipe.

[0010] Furthermore, two support feet are fixedly installed on the bottom surface of the outer shell, and they are symmetrically distributed.

[0011] In summary, this application includes at least one of the following beneficial technical effects: When using the device, seawater enters through the inlet branch pipe of the outer shell, passes through the filter barrel inside the device to filter impurities, and then flows out through the outlet branch pipe. To prevent long-term use from causing corrosion to the inner wall of the outer shell due to seawater, an anti-corrosion protective layer is installed on the inner wall. This anti-corrosion protective layer completely covers the inner surface of the outer shell and is in direct contact with seawater. The anti-corrosion protective layer can be made of corrosion-resistant materials such as polyethylene and is formed into an integral molded layer with the inner wall of the outer shell through a hot-melt process, which isolates the seawater from contact with the inner wall of the outer shell and improves the service life of the device.

[0012] When the filter canister is installed inside the outer casing, it is supported by two L-shaped support plates. The pads can be made of Teflon, and the L-shaped support plates can be made of 316L stainless steel to improve corrosion resistance. The combination of the pads and L-shaped support plates provides stable support for the filter canister.

[0013] When the filter canister is installed inside the outer casing, the outer casing is further supported by a reinforcing plate made of 316L stainless steel to improve corrosion resistance. Combined with the pad, L-shaped support plate and reinforcing plate, the filter canister is provided with stable support. Attached Figure Description

[0017] Example, refer to Figures 1-3A novel anti-corrosion suction-type seawater filter includes a housing 1 and a filter barrel 2. The housing 1 has an inlet branch pipe 11 and an outlet branch pipe 12 symmetrically arranged on its side. The filter barrel 2 is housed inside the housing 1. An anti-corrosion protective layer 13 is fixedly installed on the inner wall of the housing 1. A support component 3 for supporting the filter barrel 2 is provided on the bottom surface of the filter barrel 2, and a fixing component 4 for fixed connection with the filter barrel 2 is provided on the top surface of the housing 1. In use, seawater enters the device through the inlet branch pipe 11 of the housing 1, passes through the filter barrel 2 to filter impurities, and then flows out through the outlet branch pipe 12. To prevent corrosion of the inner wall of the housing 1 due to prolonged use, the anti-corrosion protective layer 13 completely covers the inner surface of the housing 1, directly contacting the seawater. The anti-corrosion protective layer 13 can be made of corrosion-resistant materials such as polyethylene and is integrally molded with the inner wall of the housing 1 through a hot-melt process, isolating the seawater from contacting the inner wall of the housing 1 and improving the service life of the device.

[0018] Two support components 3 are provided and symmetrically distributed on the bottom surface inside the outer casing 1. Each support component 3 includes a pad 31 and an L-shaped support plate 32. The L-shaped support plate 32 is fixedly installed on the bottom surface of the filter cartridge 2, and the pad 31 is fixedly installed on the bottom surface of the L-shaped support plate 32. The bottom surface of the pad 31 abuts against the bottom surface inside the outer casing 1. When the filter cartridge 2 is installed inside the outer casing 1, the two L-shaped support plates 32 provide support for the filter cartridge 2. The pad 31 can be made of Teflon, and the L-shaped support plate 32 can be made of 316L stainless steel to improve corrosion resistance. The combination of the pad 31 and the L-shaped support plate 32 provides stable support for the filter cartridge 2.

[0019] A reinforcing plate 33 is fixedly connected to the side of the L-shaped support plate near the pad 31, and the side of the reinforcing plate 33 away from the pad 31 abuts against the bottom surface of the filter barrel 2. When the filter barrel 2 is installed inside the outer casing 1, the reinforcing plate 33 further supports the outer casing 1. The reinforcing plate 33 is made of 316L stainless steel to improve corrosion resistance. Together with the pad 31, the L-shaped support plate 32, and the reinforcing plate 33, they provide stable support for the filter barrel 2.

[0020] Two fixing blocks 14 are fixedly installed on the outer wall of the outer casing 1, and they are symmetrical to each other. The fixing component 4 includes a cover plate 41 and screws 42. The top of the filter barrel 2 is fixedly connected to the bottom surface of the cover plate 41. There are two screws 42. An annular fixing plate 21 is fixedly installed on the top surface of the filter barrel 2. The top surface of the annular fixing plate 21 has connecting holes, and they are symmetrical to each other. The top surface of the cover plate 41 has two through holes, and they are symmetrical to each other. The top surfaces of the two fixing blocks 14 are respectively provided with threaded holes. The two screws 42 are respectively connected to the two through holes on the cover plate 41 and the connecting holes on the annular fixing plate 21, and are respectively threaded to the threaded holes on the two fixing blocks 14. The annular fixing plate 21 is located between the cover plate 41 and the outer casing 1. When the filter barrel 2 is installed inside the outer casing 1, the filter barrel 2 is placed inside the outer casing 1 with the bottom surface of the annular fixing piece 21 abutting against the top surface of the outer casing 1, and then the cover plate 41 is placed on top. Two screws 42 are used to connect the two through holes on the cover plate 41 and the connecting holes on the annular fixing piece 21, respectively, and are connected to the threaded holes on the two fixing blocks 14, so that the filter barrel 2 is fixedly installed inside the outer casing 1, which improves the stability of the device.

[0021] The outer wall of the filter barrel 2 has an arc-shaped opening 22, and an inlet guide pipe 15 is fixedly connected to the arc-shaped opening 22 of the filter barrel 2. One end of the inlet guide pipe 15 is connected to the inlet branch pipe 11. When using the device, seawater enters the device through the inlet guide pipe 15 and is introduced into the filter barrel 2 through the inlet branch pipe 11 for filtration. The precise connection between the arc-shaped opening 22 and the inlet and outlet pipes 15 achieves efficient filtration, and the water is then led out of the device through the outlet branch pipe 12.

[0022] Two support legs 16 are fixedly mounted on the bottom surface of the outer casing 1, and are symmetrically distributed. When using the device, the two support legs 16, which are symmetrically distributed, provide support for the entire device.

[0023] Working principle: When using the device, seawater enters the device through the inlet guide pipe 15 and is introduced into the filter barrel 2 for filtration through the inlet branch pipe 11. The inner wall of the outer shell 1 is protected against seawater corrosion by the anti-corrosion protective layer 13. After filtration by the filter barrel 2, the seawater is led out of the device through the outlet branch pipe 12.
