Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, and in particular to a quick-change structure for a filter element in a ship water inlet filtration device. Background Technology

[0002] During ship operation, water filtration is a crucial operation. Ships need to obtain large amounts of water from the outside for various purposes, such as cooling ship engines, providing drinking and washing water for crew members, and other water-dependent equipment. However, external water sources often contain various impurities, such as silt, suspended solids, and microorganisms. If these impurities enter the ship's water system directly without filtration, they can cause serious damage to ship equipment. For example, impurities may clog engine cooling pipes, causing engine overheating and affecting its performance and lifespan. For drinking water, impurities can affect water quality and endanger the health of crew members. Therefore, the existence of a ship's water filtration system is a necessary condition to ensure the normal operation of the ship and the safety of the crew.

[0003] Traditional ship water inlet filtration devices often have complex filter element structures. In terms of filter element installation, the connection method may involve the tight fit of multiple components and requires the use of special tools for installation. For example, some filter elements are fixed by multiple bolts and nuts. When disassembling and installing, a lot of time is required to loosen and tighten these bolts and nuts. Moreover, it is very inconvenient to operate these tools in the limited space of a ship. Furthermore, excessively long replacement time may affect the ship's voyage schedule and may even pose safety hazards due to the equipment's inability to operate normally for a long time. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides a quick-change structure for the filter element of a ship's water inlet filtration device.

[0005] This utility model is achieved using the following technical solution: a quick-change filter element structure for a ship's water inlet filtration device, comprising a filter body, a positioning sleeve fixedly connected to the upper surface of the filter body, a circular slide rail formed on the surface of the positioning sleeve, an ejection groove formed on the inner wall of the circular slide rail, a mounting base snapped onto the surface of the positioning sleeve, an extension block fixedly connected to the surface of the mounting base, an insertion shaft fixedly connected to the surface of the extension block, a telescopic spring fixedly connected inside the insertion shaft, a spring pin fixedly connected to the surface of the telescopic spring, a threaded sleeve fixedly connected to the surface of the mounting base, an assembly screw threadedly connected inside the threaded sleeve, an assembly shaft fixedly connected to the surface of the assembly screw, and a filter element screen fixedly connected to the surface of the assembly shaft.

[0006] The above technical solution facilitates quick and easy installation and removal of filter elements. Compared with traditional filter element installation structures, it does not require complicated tools or cumbersome operating procedures, thus improving the efficiency of filter element replacement and maintenance.

[0007] As a further improvement to the above solution, the filter core is disposed inside the filter body.

[0008] As a further improvement to the above solution, the insert shaft is slidably connected inside the circular slide.

[0009] As a further improvement to the above solution, the spring pin is adapted to the pop-out slot.

[0010] As a further improvement to the above solution, a metal block is fixedly connected to the surface of the mounting base.

[0011] As a further improvement to the above solution, the surface of the positioning sleeve is provided with a magnetic piece.

[0012] As a further improvement to the above solution, the metal block and the magnet sheet are in contact.

[0013] Through the above technical solution, this magnetic attraction complements the fixing function of the spring pin and the pop-out slot snap-fit ​​structure, and the dual fixing method together ensures the stability of the filter core inside the filter body.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention uses a threaded connection between the assembly shaft and the assembly screw to initially fix the filter element to the mounting base. Then, the mounting base is engaged with the positioning sleeve, fixing the filter element within the filter body. After the spring pin engages with the ejector slot to form a locking structure, the metal block and the magnetic piece contact each other, further securing the position of the mounting base. When disassembly is required, the operator presses the spring pin, causing it to compress the telescopic spring and retract into the insert shaft. Then, the mounting base is rotated again, causing the insert shaft to disengage from the ejector slot. Simultaneously, the metal block and the magnetic piece separate, separating the mounting base from the positioning sleeve, allowing for rapid disassembly of the filter element. This enables quick disassembly when the filter element needs replacement or maintenance, reducing maintenance time. Attached Figure Description

[0023] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example

[0024] Please combine Figure 1-5This embodiment of a quick-change filter element structure for a ship's water inlet filtration device includes a filter body 1. A positioning sleeve 2 is fixedly connected to the upper surface of the filter body 1. A circular slide 3 is formed on the surface of the positioning sleeve 2, and a pop-out groove 4 is formed on the inner wall of the circular slide 3. A mounting base 5 is snapped onto the surface of the positioning sleeve 2. An extension block 6 is fixedly connected to the surface of the mounting base 5. A insertion shaft 7 is fixedly connected to the surface of the extension block 6. A telescopic spring 8 is fixedly connected inside the insertion shaft 7. A spring pin 9 is fixedly connected to the surface of the telescopic spring 8. A threaded sleeve 10 is fixedly connected to the surface of the mounting base 5. An assembly screw 11 is threadedly connected inside the threaded sleeve 10. An assembly shaft 12 is fixedly connected to the surface of the assembly screw 11. A filter element screen 13 is fixedly connected to the surface of the assembly shaft 12. First, during assembly, the personnel thread the assembly shaft 12 to the assembly screw 11. Then, the insertion shaft on the surface of the mounting base 5 is... 7. Insert the shaft 7 into the circular slide 3 on the surface of the positioning sleeve 2. During insertion, the spring pin 9 on the surface of the shaft 7 will be pressured by the inner wall of the circular slide 3, thereby compressing the telescopic spring 8. After the shaft 7 is fully inserted into the circular slide 3, rotate the mounting base 5. The mounting base 5 will drive the extension block 6 and the shaft 7 to rotate along the circular slide 3. When it rotates to the position of the pop-out groove 4, the spring pin 9 will be locked into the pop-out groove 4 under the reset action of the telescopic spring 8, forming a locking structure, which will fix the mounting base 5 and the positioning sleeve 2. Since the mounting base 5 is fixed, the filter core 13 inside it will also be fixed in the filter body 1. When it is necessary to disassemble, press the spring pin 9 to compress the telescopic spring 8 and retract it into the shaft 7. Then rotate the mounting base 5 again to make the shaft 7 disengage from the position of the pop-out groove 4, thereby separating the mounting base 5 from the positioning sleeve 2, and then the filter core 13 can be easily disassembled.

[0025] The filter element 13 is disposed inside the filter body 1, so as to filter the water entering the filter body 1.

[0026] The insert shaft 7 is slidably connected inside the circular slide 3. During the assembly of the mounting base 5 and the positioning sleeve 2, the insert shaft 7 slides along the circular slide 3. This sliding connection provides guidance for the insertion and rotation of the insert shaft 7, ensuring that the insert shaft 7 can be accurately inserted into the circular slide 3 and rotated along the slide.

[0027] The spring pin 9 is adapted to the pop-out groove 4. When the insertion shaft 7 rotates to the appropriate position, the spring pin 9 can accurately engage in the pop-out groove 4 to form a snap-fit ​​structure.

[0028] A metal block 14 is fixedly connected to the surface of the mounting base 5.

[0029] The positioning sleeve 2 has a magnetic piece 15 on its surface. When the insert shaft 7 rotates inside the circular slide 3, the spring pin 9 moves to the position of the pop-out groove 4 to form a locking structure. At this time, the metal block 14 also moves to the surface of the magnetic piece 15. Since the metal block 14 and the magnetic piece 15 have magnetic attraction, they come into contact with each other, further fixing the position of the mounting base 5.

[0030] The metal block 14 and the magnet piece 15 are in contact.

[0031] The implementation principle of the quick-change filter element structure of the ship water inlet filtration device in this application embodiment is as follows: First, the assembly shaft 12 is threadedly connected to the assembly screw 11, and then the filter element screen 13 is fixed to the mounting base 5. Next, the insertion shaft 7 on the surface of the mounting base 5 is aligned with the circular slide 3 on the surface of the positioning sleeve 2 and inserted. During the insertion process, the spring pin 9 on the surface of the insertion shaft 7 will be pressured by the inner wall of the circular slide 3. This pressure will compress the telescopic spring 8. After the insertion shaft 7 is fully inserted into the circular slide 3, the mounting base 5 is rotated. The rotation of the mounting base 5 drives the extension block 6 and the insertion shaft 7 to rotate along the circular slide 3. When the insertion shaft 7 rotates to the position of the ejection groove 4, the spring pin 9 is locked into the ejection groove 4 under the reset action of the telescopic spring 8, forming a locking structure, thereby fixing the mounting base 5 and the positioning sleeve 2. Since the mounting base 5 is fixed, the filter element screen 13 inside it is also fixed to the filter. Inside body 1, the filter element is installed. After the spring pin 9 engages with the pop-out groove 4 to form a snap-fit ​​structure, the metal block 14 is fixedly connected to the surface of the mounting base 5, and the magnetic piece 15 is provided on the surface of the positioning sleeve 2. At this time, the metal block 14 moves to the surface of the magnetic piece 15. Since the metal block 14 and the magnetic piece 15 have magnetic attraction, they come into contact with each other, further fixing the position of the mounting base 5 and enhancing the stability of the filter element installation. When disassembly is required, the operator first presses the spring pin 9 to compress the telescopic spring 8 and retract it into the insertion shaft 7. Then, the mounting base 5 is rotated again to make the insertion shaft 7 disengage from the pop-out groove 4. At the same time, the metal block 15 and the magnetic piece 14 separate, thereby separating the mounting base 5 from the positioning sleeve 2. Since the mounting base 5 is separated from the positioning sleeve 2, the filter element screen 13 inside the mounting base 5 is no longer restricted by the positioning sleeve 2, and the filter element screen 13 can be easily disassembled.

[0032] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
