Description

Technical Field

[0001] This utility model relates to the field of seawater filtration technology, specifically to a quick-release structure for a marine seawater filtration system. Background Technology

[0002] The main function of marine seawater filtration systems is to remove solid impurities from seawater, such as silt, algae, plastic fragments, and marine organisms, in order to protect various equipment on board that rely on seawater for cooling and operation, and to prevent core equipment such as main seawater pumps and heat exchangers from being blocked or damaged by large pieces of debris.

[0003] For example, patent application number 202022987108.8 published on the China Patent Network, titled "A Seawater Filtration System with Siphon Self-Cleaning Function," describes a system where a filter tank is installed inside an outer tank, filter media is placed inside the filter tank, and water passage holes are formed at the bottom of the filter tank. An inlet pipe and an outlet pipe are inserted into the upper part of the outer tank. A siphon pipe passes through the top of the outer tank and is inserted into the filter tank. The inlet pipe connects to the siphon pipe. The siphon pipe extends upwards to a certain height from the outer surface of the outer tank and then bends downwards. A first vent pipe extends from the top of the siphon pipe and is inserted into the outer tank. A water storage tank is installed at the top of the outer tank, and an inlet pipe is connected to the water storage tank. A filter tank is installed below the external outlet of the siphon pipe, and a filter screen is installed at the bottom of the filter tank. A drain pipe is installed at the bottom of the filter tank, and a large slag filter grid is installed at an angle above the filter screen. This technology can filter and separate the blockages that are flushed out of the filter media when the siphon occurs, preventing the blockages from reabsorbing heat and clogging the filter media.

[0004] However, the existing filtration system has a relatively simple structure, mainly sealing the pipeline with a threaded cover plate. When the filter screen needs to be disassembled and replaced, a large number of threaded components need to be disassembled and reassembled, which is time-consuming and labor-intensive, affecting the efficiency of replacement and maintenance.

[0005] Therefore, it is necessary to redesign and modify the quick-release structure of the filter screen in marine seawater filtration systems. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a quick-release structure for the filter screen of a marine seawater filtration system. This structure facilitates easy disassembly and replacement of the filter screen, solving the problem that existing filtration systems have a relatively simple structure, mainly sealing the pipeline through threaded cover plates. When the filter screen needs to be disassembled and replaced, a large number of threaded components need to be disassembled and reassembled, which is time-consuming, labor-intensive, and affects the efficiency of replacement and maintenance.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a quick-release filter structure for a marine seawater filtration system, including pipelines; The top of the pipeline is provided with a cover plate, and a filter element is inserted into the pipeline. The filter element can be separated to the outside of the pipeline by insertion and removal when the cover plate is opened. A connecting frame is provided on the front of the tank. A pressure rod is installed inside the connecting frame through a pressure structure. The surface of the pressure rod is covered with a rubber sleeve. The pressure structure can use the pressure rod to apply downward closing pressure to the cover plate.

[0008] As a preferred embodiment of this utility model, the pressurizing structure includes a bidirectional screw rod that is movably connected inside the connecting frame via a bearing. Both sides of the surface of the bidirectional screw rod are threaded with threaded sleeves. The pressure rod is fixedly connected to the back of the threaded sleeves and is located at the top of the cover plate and in contact with the surface of the cover plate.

[0009] In a preferred embodiment of this invention, both sides of the bidirectional screw extend to the outer side of the connecting frame, and both ends of the bidirectional screw are fixedly connected to a rotating wheel.

[0010] As a preferred embodiment of this utility model, both ends of the pipeline are connected to valves, and a valve stem is provided on the front of the valve, which can control the opening and closing of the valve.

[0011] In a preferred embodiment of this invention, a sleeve plate is fitted onto the surface of the valve stem. The side of the sleeve plate away from the valve stem extends to the front of the threaded sleeve. A push rod is fixedly connected to the front of the threaded sleeve. The side of the push rod away from the threaded sleeve extends into the interior of the sleeve plate and is slidably connected to the sleeve plate. A buffer frame is connected to the outer side of the sleeve plate. The push rod can move into the interior of the buffer frame and be slidably connected to the buffer frame when sliding outward.

[0012] As a preferred embodiment of this utility model, a guide strip is fixedly connected inside the connecting frame, and the guide strip extends into the interior of the threaded sleeve from the side away from the connecting frame and is slidably connected to the threaded sleeve.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses a pressurized cover plate to change the filter element installation method from cumbersome threaded locking to simple vertical insertion and removal, laying a structural foundation for quick assembly and disassembly. At the same time, the pressurized structure ensures that the cover plate can provide a stable and reliable sealing force when closed.

[0014] 2. This utility model adopts a mechanism of bidirectional screw and screw sleeve transmission. A single bidirectional screw can drive the pressure rods on both sides to move synchronously and at equal distances, ensuring that the cover plate is subjected to uniform force and avoiding poor sealing. The inherent self-locking characteristic of the screw drive can effectively maintain pressure after clamping, preventing equipment vibration from causing loosening and enhancing reliability.

[0015] 3. This utility model greatly improves the convenience of operation and ergonomics by installing rotating wheels at both ends of the bidirectional screw. Operators can easily approach and apply force from both sides of the structure without being limited by the workspace. The rotating wheels themselves are also less strenuous and more in line with manual operation habits than directly rotating the smooth rod.

[0016] 4. This utility model introduces valve assemblies at both ends of the pipeline to link the filter element replacement operation with the safety of the system process. Before replacing the filter element, the valve must be closed to cut off the water flow. This is a necessary step to prevent media leakage and ensure the safety of maintenance personnel.

[0017] 5. This utility model links the linear motion of the screw sleeve with the rotational motion of the valve stem through the push rod, sleeve plate and buffer frame, thus forcibly establishing a safe operating procedure and effectively eliminating the serious risk of accidentally opening the cover plate when the system is not isolated.

[0018] 6. This utility model ensures the accuracy and reliability of mechanical movement by adding a guide bar. The guide bar constrains the screw sleeve, preventing it from rotating unnecessarily when the screw rotates, and ensuring that the screw sleeve can only make smooth linear movement along the preset path.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 4 As shown, the present invention provides a quick-release structure for a marine seawater filtration system, including a pipeline 1; The top of the pipeline 1 is provided with a cover plate 2, and a filter element 3 is inserted into the inside of the pipeline 1. The filter element 3 can be separated to the outside of the pipeline 1 by insertion and removal when the cover plate 2 is opened. A connecting frame 4 is provided on the front of the tank. A pressure rod 5 is installed inside the connecting frame 4 through a pressure structure. A rubber sleeve 6 is fitted on the surface of the pressure rod 5. The pressure structure can apply downward closing pressure to the cover plate 2 using the pressure rod 5.

[0023] refer to Figure 1 The pressurizing structure includes a bidirectional screw 7 that is movably connected inside the connecting frame 4 via a bearing. Both sides of the surface of the bidirectional screw 7 are threaded with screw sleeves 8. The pressure rod 5 is fixedly connected to the back of the screw sleeves 8. The pressure rod 5 is located at the top of the cover plate 2 and contacts the surface of the cover plate 2.

[0024] As a technical optimization of this utility model, by adopting a mechanism of bidirectional screw 7 and screw sleeve 8, a single bidirectional screw 7 can drive the pressure rods 5 on both sides to move synchronously and at equal distances, ensuring that the cover plate 2 is subjected to uniform force and avoiding poor sealing. The inherent self-locking characteristic of the thread drive can effectively maintain pressure after pressing, prevent equipment vibration from causing loosening, and enhance reliability.

[0025] refer to Figure 4 Both sides of the bidirectional screw 7 extend to the outside of the connecting frame 4, and both ends of the bidirectional screw 7 are fixedly connected to the rotating wheel 9.

[0026] As a technical optimization of this utility model, the addition of rotating wheels 9 at both ends of the bidirectional screw 7 greatly improves the convenience of operation and ergonomics. Operators can easily approach and apply force from both sides of the structure without being limited by the workspace. The rotating wheels 9 themselves are also more labor-saving and more in line with manual operation habits than directly rotating the smooth rod.

[0027] refer to Figure 2 Both ends of the pipeline 1 are connected to valves 10. A valve stem 11 is provided on the front of the valve 10, and the valve stem 11 can control the opening and closing of the valve 10.

[0028] As a technical optimization of this utility model, by introducing valve 10 components at both ends of pipeline 1, the filter element 3 replacement operation is linked to the system process safety. Before replacing the filter element 3, valve 10 must be closed to cut off the water flow. This is a necessary step to prevent media leakage and ensure the safety of maintenance personnel.

[0029] refer to Figure 4 A sleeve plate 12 is fitted on the surface of the valve stem 11. The side of the sleeve plate 12 away from the valve stem 11 extends to the front of the threaded sleeve 8. A push rod 13 is fixedly connected to the front of the threaded sleeve 8. The side of the push rod 13 away from the threaded sleeve 8 extends into the interior of the sleeve plate 12 and is slidably connected to the sleeve plate 12. A buffer frame 14 is connected to the outside of the sleeve plate 12. The push rod 13 can move into the interior of the buffer frame 14 and be slidably connected to the buffer frame 14 when sliding outward.

[0030] As a technical optimization of this utility model, the linear motion of the screw sleeve 8 and the rotational motion of the valve stem 11 are linked by the push rod 13, the sleeve plate 12 and the buffer frame 14, thus forcibly establishing a safe operating procedure and effectively eliminating the serious risk of accidentally opening the cover plate 2 when the system is not isolated.

[0031] refer to Figure 4 A guide bar 15 is fixedly connected inside the connecting frame 4. The guide bar 15 extends into the inside of the screw sleeve 8 from the side away from the connecting frame 4 and is slidably connected to the screw sleeve 8.

[0032] As a technical optimization of this utility model, by adding a guide bar 15, the accuracy and reliability of mechanical movement are ensured. The guide bar 15 constrains the screw sleeve 8, preventing it from rotating unnecessarily when the screw rotates, and ensuring that the screw sleeve 8 can only make smooth linear movement along the preset path.

[0033] The working principle and usage process of this utility model are as follows: When the filter element 3 needs to be replaced, the operator rotates the rotating wheel 9 to drive the bidirectional screw 7 to rotate. The bidirectional screw 7 uses its thread to push the screw sleeve 8 to move in opposite directions. During the movement of the screw sleeve 8, the pressure rod 5 and the push rod 13 move synchronously. The push rod 13 slides inside the sleeve plate 12, which enables the sleeve plate 12 to rotate with the valve stem 11 and close the valve 10. At the same time, the continuously moving push rod 13 keeps the valve 10 closed when it moves into the buffer frame 14. When the screw sleeve 8 moves with the pressure rod 5 to both sides of the cover plate 2, the cover plate 2 is released from the squeezed state. The user can separate the cover plate 2 from the pipeline 1 and replace the filter element 3.

[0034] In summary, the quick-release structure of the marine seawater filtration system transforms the installation method of the filter element 3 from cumbersome threaded locking to simple vertical insertion and removal through the pressurized cover plate 2, laying the structural foundation for quick assembly and disassembly. At the same time, the pressurized structure ensures that the cover plate 2 provides a stable and reliable sealing force when closed.
