Technical Field

[0001] The utility model relates to the technical field of seawater filters, in particular to a seawater filter which is easy to install. Background Art

[0002] The seawater filter is a device that separates seawater impurities and harmful substances. It can filter out impurities, dust, rust and other harmful substances in the seawater entering the cooler, thereby protecting the normal operation of the cooling system.

[0003] The Chinese patent with announcement number CN221385493U discloses a high-efficiency titanium seawater filter, which includes a filter cartridge, a water inlet at one end of the filter cartridge, a crushing blade at one end of the filter cartridge near the water inlet, a driving motor fixedly connected to the crushing blade, a filter screen fixedly connected to the central axis of the filter cartridge, a vibration motor symmetrically fixedly connected to one end of the filter screen, a sealing cover movably connected to the upper end of the vibration motor, the sealing cover fixedly connected to the filter cartridge, and the end of the filter screen away from the water inlet is fixedly connected to the sealing cover, the lower end of the filter cartridge is hinged with a flip cover by a hinge, and a water outlet is provided at one end of the filter cartridge. The beneficial effect of the utility model is that the crushing blade can crush the sediment and impurities in the filter cartridge that have not flowed out with the seawater during the transmission process to prevent large impurities from being entangled and accumulated, and the filter screen is connected to the vibration motor, and the filter screen generates high-frequency oscillation under the action of the vibration motor, which can shake off and separate impurities accumulated in the filter screen mesh.

[0004] Regarding the above-mentioned related technologies, in the existing technology, staff use a filter to filter seawater, use a vibration motor to shake off impurities on the filter, and discharge them from the flip cover. However, the impurities will not only be retained on the filter, but some particulate impurities will also adhere to the inner wall of the filter cartridge. These impurities cannot be affected by the vibration motor. The staff have to flush and maintain the inner wall of the filter cartridge. The filter cartridge is large in size and weight, which increases the difficulty of filter cartridge maintenance and reduces the maintenance efficiency of the seawater filter. Utility Model Content

[0005] In order to improve the maintenance efficiency of the seawater filter, the present application provides a seawater filter that is easy to install.

[0006] This application provides a seawater filter that is easy to install and adopts the following technical solutions:

[0007] A seawater filter that is easy to install includes a shell and a filter cartridge, wherein the top end of the shell is provided with a mounting port, the side walls of the shell are provided with a water inlet and a water outlet, the bottom end of the shell is provided with a discharge port, the discharge port is provided with a blocking member for blocking the discharge port, the top end of the shell is provided with a shell cover and a limiting component for limiting the box cover, the filter cartridge is arranged in the shell with a gap between it and the inner wall of the shell, the top end of the filter cartridge is provided with an opening, the side walls of the filter cartridge are provided with a water inlet hole and a plurality of water filtering holes, the water inlet holes are aligned with the water inlet, an extension ring is connected to the water inlet, the extension ring is in contact with the side wall of the filter cartridge, and a mounting component for mounting the filter cartridge is provided on the shell.

[0008] By adopting the above technical solution, during installation, the staff uses the installation component to install the filter cartridge inside the shell, aligning the water inlet hole with the water inlet hole, and the extension ring fits the side wall of the filter cartridge. Finally, the shell cover is installed on the top of the shell using the limiting component, thereby realizing the installation of the seawater filter. During filtration, seawater directly enters the filter cartridge from the water inlet hole, and the filtered seawater is discharged from the water outlet. The impurities in the seawater are retained inside the filter cartridge. The staff uses the filter cartridge to filter seawater and retains the impurities in the seawater inside the filter cartridge. At the same time, the extension ring is used to separate the inside of the filter cartridge from the inside of the shell, reducing the possibility of seawater impurities entering the shell. This allows the staff to use the seawater filter for a long time without the need for maintenance. They only need to take out the filter cartridge and clean it. Compared with the existing technology, the maintenance difficulty of the seawater filter is reduced and the maintenance efficiency of the seawater filter is improved.

[0009] Optionally, the mounting assembly includes a first gasket, a second gasket and a connecting ring, a placement step is opened at the top of the shell, the first gasket and the second gasket are both placed on the placement step, the connecting ring is connected to the filter cartridge and is located between the first gasket and the second gasket, and the first gasket and the second gasket are both located between the shell cover and the placement step.

[0010] By adopting the above technical solution, when installing the filter cartridge, the staff places the first gasket on the placement step, then places the connecting ring on the filter cartridge on the first gasket, then places the second gasket on the connecting ring, and finally covers the shell cover, and uses the limiting assembly to limit the shell cover to realize the installation of the filter cartridge.

[0011] Optionally, a support column is connected to the inner bottom wall of the shell, a fixed protrusion is connected to the support column, a plurality of water-permeable holes are opened on the surface of the support column, a positioning hole is opened at the bottom end of the filter cartridge corresponding to the position of the fixed protrusion, and the fixed protrusion is plugged into the positioning hole.

[0012] With this technical solution, when seawater enters the filter cartridge, it impacts it, causing it to vibrate. This can cause the bottom end of the filter cartridge to become vacant, resulting in excessive vibration and the risk of seawater carrying impurities leaking into the housing through the extension ring. By installing support columns to stabilize the bottom end of the filter cartridge, the staff reduced the likelihood of the filter cartridge vibrating excessively due to impact, further reducing the possibility of seawater impurities entering the housing.

[0013] Optionally, a limiting sleeve is connected to the side wall of the filter cartridge at a position corresponding to the water inlet hole. The limiting sleeve is U-shaped, with the open end of the limiting sleeve facing downward. When the filter cartridge is installed, the limiting sleeve is mounted on the extension ring.

[0014] By adopting this technical solution, the filter cartridge's installation angle is not restricted during installation, requiring workers to manually align the water inlet with the water inlet, which increases the difficulty of filter installation. During installation, workers place a restricting sleeve on the extension ring as they lower the filter cartridge. This restricts the filter cartridge's installation angle, eliminating the need for manual alignment of the water inlet and water inlet, thus reducing the difficulty of filter installation. The restricting sleeve also improves filter cartridge installation stability, further reducing vibration amplitude in the center of the filter cartridge.

[0015] Optionally, the limiting assembly includes a connecting plate, a hinge bolt and a mounting nut, the connecting plate being connected to several blocks on the shell cover, an avoidance groove being opened on the connecting plate, a number of hinge bolts being arranged on the surface of the shell, the hinge bolts corresponding to the connecting plate one-to-one, one end of the hinge bolt being rotatably connected to the shell, the mounting nut being threadedly engaged with the hinge bolt, and when the shell cover is limited, the hinge bolt is located in the avoidance groove and the mounting nut is pressed against the connecting plate.

[0016] By adopting the above technical solution, when installing the shell cover, the staff places the shell cover on the second gasket to cover the top of the shell, then rotates the movable bolt to make the movable bolt enter the avoidance groove, and rotates the mounting nut until the mounting nut is tight against the connecting plate, thereby limiting the freedom of the shell cover and realizing the installation of the shell cover.

[0017] Optionally, a plurality of fixing plates are connected to the side wall of the shell near the bottom end, and a support seat is connected to the fixing plate by bolts, and the support seat is arranged in an L shape.

[0018] By adopting the above technical solution, the staff uses the support seat to raise the shell to facilitate the installation of the water inlet and outlet pipes. At the same time, the staff can also use the support seat as a connector between the shell and other objects, which facilitates the installation of the shell.

[0019] Optionally, the mounting assembly includes a positioning ring, a connecting column and a limiting flange, the positioning ring is connected to the shell cover, several connecting columns are connected to the positioning ring, the filter cartridge is sleeved on the positioning ring, a U-shaped groove is opened on the filter cartridge at a position corresponding to the connecting column, the connecting column is located in the U-shaped groove, and one limiting flange is connected to each side wall of the U-shaped groove. When the filter cartridge is installed, the connecting column is snap-fitted between the limiting flange and the bottom end of the U-shaped groove.

[0020] By adopting the above technical solution, when installing the filter cartridge, the staff will put the filter cartridge on the positioning ring, so that the connecting column enters the U-shaped groove, and finally snap the connecting column into place between the limiting flange and the bottom end of the U-shaped groove, thereby limiting the freedom of the filter cartridge. Finally, the shell cover is installed on the shell using the limiting assembly to realize the installation of the filter cartridge.

[0021] Optionally, a plurality of reinforcement strips are connected to the surface of the filter cartridge.

[0022] The above technical solution creates a thin, cylindrical filter cartridge. Over time, the center of the filter cartridge is susceptible to deformation due to the impact of seawater. Reinforcement strips were used to increase the cartridge's structural strength, reducing the likelihood of deformation and extending its service life.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. During installation, the staff uses the installation component to install the filter cartridge inside the shell, aligning the water inlet hole with the water inlet hole, and the extension ring fits the side wall of the filter cartridge. Finally, the limiting component is used to install the shell cover on the top of the shell to realize the installation of the seawater filter. During filtration, seawater directly enters the filter cartridge from the water inlet hole, and the filtered seawater is discharged from the water outlet. The impurities in the seawater are retained inside the filter cartridge. The staff uses the filter cartridge to filter seawater and retain the impurities in the seawater in the filter cartridge. At the same time, the extension ring is used to separate the inside of the filter cartridge from the inside of the shell, reducing the possibility of seawater impurities entering the shell. This allows the staff to use the seawater filter for a long time without maintenance. They only need to take out the filter cartridge and clean it. Compared with the existing technology, the maintenance difficulty of the seawater filter is reduced and the maintenance efficiency of the seawater filter is improved;

[0025] 2. When installing the filter cartridge, the staff placed the first gasket on the placement step, then placed the connecting ring on the filter cartridge on the first gasket, and then placed the second gasket on the connecting ring. Finally, the shell cover was closed and the shell cover was restrained by the restraining assembly to complete the installation of the filter cartridge.

[0026] 3. When installing the filter cartridge, the staff will put the filter cartridge on the positioning ring so that the connecting column enters the U-shaped groove, and finally snap the connecting column into place between the limiting flange and the bottom end of the U-shaped groove, thereby limiting the freedom of the filter cartridge. Finally, the shell cover is installed on the shell using the limiting assembly to complete the installation of the filter cartridge. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following is combined with Figures 1-6 This application is described in further detail.

[0035] Example 1 of the present application discloses a seawater filter that is easy to install. Figure 1 and Figure 2 The easy-to-install seawater filter comprises a housing 1 and a filter cartridge 2. The top of housing 1 is open, and the sidewalls are provided with a water inlet 11 and a water outlet 12. A drain port is provided at the bottom of housing 1, and a plug 13 is provided at the drain port. This plug 13 is a screw plug that is threadedly engaged with the drain port. The drain port is used to discharge excess seawater from the interior of housing 1.

[0036] Reference Figure 2 and Figure 3 The filter cartridge 2 is placed inside the filter cartridge 2, with a gap between the filter cartridge 2 and the inner wall of the housing 1. A water inlet 21 and several water filtration holes are formed on the side wall of the filter cartridge 2. The water inlet 21 is aligned with the water inlet 11. An extension ring 14 is welded to the water inlet 11, and the end of the extension ring 14 fits against the side wall of the filter cartridge 2. A restriction sleeve 22 is welded to the filter cartridge 2. The restriction sleeve 22 is U-shaped, with the open end of the restriction sleeve 22 facing downward. The restriction sleeve 22 is mounted on the extension ring 14 and is used to limit the installation angle of the filter cartridge 2.

[0037] Reference Figure 2 、 Figure 3 and Figure 4 A mounting assembly 3 is provided between the filter cartridge 2 and the housing 1. The mounting assembly 3 includes a first gasket 31, a second gasket 32, and a connecting ring 33. The connecting ring 33 is welded to the filter cartridge 2. A placement step is provided at the top of the housing 1. The first gasket 31 is placed on the placement step. The connecting ring 33 is placed above the first gasket 31, and the second gasket 32 ​​is placed above the connecting ring 33.

[0038] Reference Figure 2 and Figure 3 The top of the shell 1 is provided with a shell cover 15 and a limiting assembly 4, which includes a connecting plate 41, a swing bolt 42 and a mounting nut 43. The shell 1 is placed on the second washer 32 and is partially located in the placement step. Several connecting plates 41 are welded to the shell cover 15. The connecting plates 41 are evenly distributed axially around the axis of the shell cover 15, and avoidance grooves are provided at the ends of the connecting plates 41. An ear plate is welded to the position of the shell 1 corresponding to the connecting plate 41, one end of the swing bolt 42 is hinged to the ear plate, and the mounting nut 43 is threadedly fitted on the swing bolt.

[0039] During installation, the staff places the first gasket 31 on the placement step, places the filter cartridge 2 into the shell 1, so that the limiting sleeve 22 is placed on the extension ring 14, and the connecting ring 33 is placed on the first gasket 31, and then places the second gasket 32 ​​on the connecting ring 33, covers the shell cover 15, turns the movable bolt 42, and turns the mounting nut 43 until the mounting nut 43 is pressed against the connecting plate 41, thereby completing the installation of the filter cartridge 2.

[0040] Reference Figure 3 To enhance the installation stability of the filter cartridge 2, a support column 16 is welded to the inner bottom wall of the housing 1. Several water-permeable holes are formed in the sidewalls of the support column 16. A fixing bump 161 is fixedly connected to the top of the support column 16. A positioning hole is formed at the bottom end of the filter cartridge 2, into which the fixing bump 161 is inserted. The support block and fixing bump 161 stabilize the bottom end of the filter cartridge 2, thereby reducing the vibration amplitude of the filter cartridge 2.

[0041] Reference Figure 3 The shell cover 15 is provided with an air vent, and the air vent is threadedly fitted with an air vent bolt 151.

[0042] As seawater is filtered, the interior of the housing 1 fills with more and more seawater. However, if the air inside the housing 1 is not promptly discharged, the internal pressure of the housing 1 will increase, affecting the flow rate of the seawater. The vent is used to discharge the gas inside the housing 1 to reduce the internal pressure of the housing 1. The vent bolt 151 is used to block the vent.

[0043] Reference Figure 2 To facilitate installation of the housing 1, several fixing plates are welded to the sidewalls near the bottom of the housing 1. Two fixing plates are used in this embodiment. Bolts connect these fixing plates to support bases 17, which are L-shaped plates. Support bases 17 allow staff to raise the housing 1 and facilitate connection to other objects.

[0044] Reference Figure 2 In order to reduce the possibility of rust on the shell 1 and the filter cartridge 2, the shell 1 and the filter cartridge 2 are made of titanium alloy.

[0045] The implementation principle of a seawater filter that is easy to install in Example 1 of the present application is as follows: during installation, the staff places the first gasket 31 on the placement step, places the filter cartridge 2 into the housing 1, so that the limiting sleeve 22 is sleeved on the extension ring 14, and the connecting ring 33 is placed on the first gasket 31, and then the second gasket 32 ​​is placed on the connecting ring 33, the fixing protrusion 161 is inserted into the positioning hole, the shell cover 15 is placed on the second gasket 32, the movable bolt 42 is rotated into the avoidance groove, and the mounting nut 43 is rotated until the mounting nut 43 is tightly against the connecting plate 41, thereby completing the installation of the seawater filter.

[0046] The staff uses the filter cartridge 2 to filter seawater and retains impurities in the seawater in the filter cartridge 2. At the same time, the extension ring 14 is used to separate the interior of the filter cartridge 2 from the interior of the shell 1, reducing the possibility of seawater impurities entering the interior of the shell 1. The staff does not need to perform maintenance after using the seawater filter for a long time. They only need to take out the filter cartridge 2 and clean it. Compared with the existing technology, the maintenance difficulty of the seawater filter is reduced and the maintenance efficiency of the seawater filter is improved.

[0048] Reference Figure 5 and Figure 6The mounting assembly 3 includes a positioning ring 34, connecting posts 35, and a limiting flange 36. The positioning ring 34 is fixedly connected to the bottom wall of the housing cover 15. Several connecting posts 35 are fixedly connected to the outer ring wall of the positioning ring 34; in this embodiment, two are used as an example. A U-shaped groove 23 is formed at the top of the filter cartridge 2 at the position corresponding to the connecting posts 35. A limiting flange 36 is fixedly connected to each side wall of the U-shaped groove 23.

[0049] When installing the filter cartridge 2, the staff will put the filter cartridge 2 on the positioning ring 34, so that the connecting column 35 enters the U-shaped groove 23, and the connecting column 35 is snap-fitted between the limiting flange 36 and the bottom end of the U-shaped groove 23 to limit the filter cartridge 2. Then, the shell cover 15 is covered, the limiting sleeve 22 is put on the extension ring 14, and the fixing protrusion 161 is inserted into the positioning hole. Finally, the limiting component 4 is used to limit the shell cover 15 to realize the installation of the filter cartridge 2.
