Description

Technical Field

[0001] The utility model relates to the technical field of a filter element replacement structure, in particular to a marine filter which is convenient for replacing the filter element. Background Art

[0002] A filter is a filter. Marine filters are mainly used to filter water, especially on ships. In order to save water when sailing on the sea, ships sometimes need to use seawater. However, seawater cannot be used directly, so a filter is needed. After filtering, it is desalinated using desalination equipment before it can be used.

[0003] Because seawater contains a lot of impurities and salt, over time, a lot of impurities and salt particles will adhere to the filter element in the filter. In order to ensure smooth subsequent use of the filter, multiple filter elements need to be replaced. The current replacement requires removing the connecting screws and nuts one by one to disassemble the equipment and then take out the filter element for replacement. The process is cumbersome and time-consuming, and the filter element is generally installed on the equipment with screws, which makes the disassembly and assembly of the filter element a cumbersome process. For this reason, a filter is set up to facilitate the replacement of the filter element. Utility Model Content

[0004] The technical solution adopted by the utility model to solve the technical problem is: a marine filter that is easy to replace the filter element, including a filter tank, both side walls of the filter tank are fixedly connected with an inlet and outlet pipe, a cover plate is set above the filter tank, the middle of the bottom side wall of the cover plate is fixedly connected with a mounting plate, a filter screen is set in the filter tank, the middle of the end of the filter screen close to the mounting plate is fixedly connected with a docking column, the outer wall of the docking column is evenly fixedly connected with four elastic card blocks, the inner wall of the mounting plate is evenly opened with card grooves corresponding to the elastic card blocks, and the docking column is detachably plugged into the mounting plate through the elastic card block buckle.

[0005] As a preferred technical solution of the utility model, a sealing ring is fixedly connected to the outer wall of the mounting plate, and the sealing ring is a conical structure. The card slot is tightly fitted with the inner wall of the top of the filter tank. Both side walls of the filter are fixedly connected with a limiting plate. Limiting grooves are provided on the opposite side walls of the filter tank. The limiting plate is inserted in the limiting groove. The height of the filter is the same as that of the filter tank.

[0006] As a preferred technical solution of the utility model, the cover plate is evenly fixedly connected with four fixing plates near the bottom edge, a rotating column is rotatably connected through the middle of the fixing plate, a driven plate is fixedly connected to the bottom end of the rotating column, four locking plates are evenly fixedly connected with the position near the top edge of the filter tank, an insertion hole is opened through the middle of the locking plate, the locking plate corresponds to the fixing plate, two pressing plates are fixedly connected to the bottom side wall of the locking plate, and top support plates are fixedly connected with the driven plate near the edges at both ends, and the top support plates correspond to the pressing plates.

[0007] The utility model has the following advantages: the cover plate is taken off from the top of the filter tank, and the filter screen is pulled out of the filter tank, and then the filter screen is pulled out of the mounting plate by force, and then a new filter screen is plugged into the mounting plate through the docking column. Because the elastic card block is an elastic structure, it will first shrink during the plugging process. When the end of the elastic card block is at the same level as the card slot, it is plugged into the card slot under the action of elasticity to achieve the connection between the mounting plate and the filter screen. The buckle connection method can effectively improve the efficiency of disassembly and assembly, and effectively improve the convenience of filter element replacement;

[0008] Rotating the rotating column can drive the driven plate to rotate synchronously, so as to disengage the top support plate from under the corresponding pressing plate, and align the driven plate with the through hole, and then lift the cover plate upwards, and at the same time pull the driven plate out from under the locking plate through the through hole to achieve disassembly of the cover plate. There is no need to remove the screws, just simply rotate the rotating column, which effectively improves the convenience of disassembly and assembly. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0014] Please refer to Figure 1-4 The utility model is a marine filter that is easy to replace the filter element, including a filter tank 1, both side walls of the filter tank 1 are fixedly connected with an inlet and outlet pipe 2, a cover plate 5 is set above the filter tank 1, and a mounting plate 14 is fixedly connected in the middle of the bottom side wall of the cover plate 5, a filter screen 9 is set in the filter tank 1, and a docking column 17 is fixedly connected in the middle of the end of the filter screen 9 close to the mounting plate 14, and the outer wall of the docking column 17 is evenly fixedly connected with four elastic card blocks 18, and the inner wall of the mounting plate 14 is evenly opened with card grooves 15 corresponding to the elastic card blocks 18, and the docking column 17 is detachably plugged into the mounting plate 14 through the elastic card blocks 18;

[0015] The outer wall of the mounting plate 14 is fixedly connected with a sealing ring 16, which is a conical structure. The card slot 15 fits tightly with the inner wall of the top of the filter tank 1. The side walls of the filter screen 9 are fixedly connected with the limiting plates 11. The limiting grooves 10 are provided on the opposite side walls of the filter tank 1. The limiting plates 11 are inserted into the limiting grooves 10. The height of the filter screen 9 is the same as that of the filter tank 1.

[0016] The preferred technical effect of this solution is to remove the cover plate 5 from the top of the filter tank 1, then lift the cover plate 5 upwards, and simultaneously pull the filter screen 9 out of the filter tank 1, and after the filter screen 9 is completely pulled out, forcibly pull it out of the mounting plate 14, and then insert the new filter screen 9 into the mounting plate 14. As the docking column 17 is gradually inserted, the elastic card block 18 will be elastically driven to be connected to the corresponding card slot 15 to achieve a stable connection, thereby improving the convenience of disassembly and assembly between the filter screen 9 and the cover plate 5.

[0017] The cover plate 5 is evenly fixedly connected with four fixing plates 6 near the bottom edge, a rotating column 7 is rotatably connected through the middle of the fixing plate 6, and a driven plate 8 is fixedly connected to the bottom end of the rotating column 7. The filter tank 1 is evenly fixedly connected with four locking plates 3 near the top edge, and an insertion hole 4 is opened through the middle of the locking plate 3, and the locking plate 3 corresponds to the fixing plate 6. Two pressing plates 13 are fixedly connected to the bottom side wall of the locking plate 3, and top support plates 12 are fixedly connected to the driven plate 8 near the edges at both ends, and the top support plates 12 correspond to the pressing plates 13.

[0018] The preferred technical effect of this solution is that when it is necessary to remove the cover plate 5, first rotate the rotating column 7, and adjust the driven plate 8 to a state aligned with the insertion hole 4 through the rotation of the rotating column 7, and at the same time, make the top support plate 12 detach from the pressing plate 13, and then lift the cover plate 5 upward to bring the driven plate 8 out from under the locking plate 3, and at the same time remove the cover plate 5 from the top of the filter tank 1, and then replace the filter screen 9, which effectively reduces the cumbersomeness of disassembling the traditional cover plate 5, thereby improving the convenience of disassembly and assembly.

[0019] Specifically, when the utility model is used, the cover plate 5 and the filter tank 1 are set up into a detachable structure. In order to ensure the sealing of the connection, a sealing ring 16 is set on the outer wall of the mounting plate 14. When the cover plate 5 is connected to the top of the filter tank 1, the sealing ring 16 fits with the inner wall of the filter tank 1. Because the sealing ring 16 is a conical structure, the tightness of the sealing ring 16 and the inside of the filter tank 1 will gradually increase as the cover plate 5 descends, thereby increasing the sealing. When the cover plate 5 is connected to the filter tank 1, the driven plate 8 is aligned with the insertion hole 4, and then the driven plate 8 is inserted under the locking plate 3 through the insertion hole 4, and then the driven plate 8 is rotated to drive the top support plate 12 to move to the bottom of the pressing plate 13. Because the top support plate 12 and the pressing plate 13 do not have corresponding wedge structures, Therefore, the contact between the two will generate a downward pulling force, thereby improving the stability of the connection. At the same time, there is no need for cumbersome rotation like a screw connection, thereby improving the convenience of disassembly and rotation. At the same time, because the filter screen 9 and the mounting plate 14 are set up as a snap connection, it is only necessary to insert the docking column 17 forcefully into the mounting plate 14. At this time, the elastic card block 18 will shrink under pressure. When the end of the elastic card block 18 is aligned with the card slot 15, the end of the elastic card block 18 will be elastically driven to be stuck in the card slot 15, thereby achieving a quick connection. When disassembling, the elastic card block 18 will be pulled outward. At the same time, the end of the elastic card block 18 and the card slot 15 are corresponding arc structures. Therefore, when the end of the elastic card block 18 is subjected to force, it will be squeezed and detached from the card slot 15, thereby achieving the disassembly function.

[0020] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.

[0021] Other parts of the present invention not described in detail belong to the prior art and will not be described here.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
