Technical Field

[0001] This utility model relates to the field of filter technology, specifically to a filter with an easy-to-disassemble filter element. Background Technology

[0002] Filters are an indispensable device in pipelines that transport media. They are usually installed on pressure reducing valves, pressure relief valves, and level control valves to facilitate the inlet of other equipment. After the filter cartridge with a filter screen of a certain size is installed, impurities are blocked. When cleaning is required, simply remove the detachable filter element, clean it, and reinstall it.

[0003] However, many filters nowadays have a rather cumbersome filter element removal process when the filter element needs to be replaced. The filter body needs to be removed from the equipment in order to easily remove the filter element, which brings great trouble to the filter element replacement work.

[0004] In view of this, the present invention proposes a filter with an easy-to-disassemble filter element. Utility Model Content

[0005] This utility model proposes a filter with an easy-to-disassemble filter element, which solves the problem that many filters currently require a cumbersome disassembly process when the filter element needs to be replaced. The filter body needs to be removed from the installation equipment before the filter element can be easily disassembled, which brings great trouble to the filter element replacement work.

[0006] The technical solution of this utility model is as follows: A filter with an easy-to-disassemble filter element includes a housing. A first spring is fixedly connected to the bottom inner wall of the housing. A base plate is fixedly connected to the top of the first spring. The filter element body located inside the housing is attached to the top of the base plate. A sealing cover is rotatably connected to the side of the housing. A rotating ring is threadedly connected to the surface of the housing. A slot is provided inside the rotating ring. A first embedding rod is slidably connected inside the slot. A second embedding rod is fixedly connected to one side of the first embedding rod and slidably connected to the rotating ring. A fixing block is fixedly connected to the top of the first embedding rod. A connecting plate fixedly connected to the housing is provided below the fixing block. A connecting rod is slidably connected inside the connecting plate. An insert plate embedded inside the sealing cover is fixedly connected to the tail of the connecting rod. A second spring fixedly connected to the connecting plate is provided on one side of the insert plate.

[0007] Preferably, a water inlet is fixedly connected to the left side of the outer casing, a conduit is fixedly connected to the bottom of the outer casing, a nozzle is fixedly connected to the bottom of the conduit, a retaining ring is fixedly connected to the surface of the nozzle, and an observation port is fixedly connected to the surface of the outer casing.

[0008] Preferably, the filter element body is in contact with the sealing cap.

[0009] Preferably, the slot is arranged in a ring about the center of the rotating ring.

[0010] Preferably, the second embedding rod is perpendicular to the first embedding rod, and both the second embedding rod and the first embedding rod are in close contact with the rotating ring.

[0011] Preferably, the insert plate and the sealing cover fit tightly together, and the connecting rod forms a sliding structure inside the connecting plate through a second spring.

[0012] Preferably, the bottom of the fixing block is connected to the outer shell via a telescopic rod, wherein the telescopic rod consists of two sets of vertical rods of different sizes that slide and fit together.

[0013] Preferably, when the insert plate is embedded inside the sealing cover, it is located on the movement trajectory of the fixing block, and the approach surfaces of the insert plate and the fixing block are designed to be inclined.

[0014] Preferably, in the filter with easily removable filter element according to claim 1, the retaining ring surrounds the nozzle and the bottom of the retaining ring is lower than the nozzle.

[0015] The working principle and beneficial effects of this utility model are as follows:

[0016] In this invention, by setting a slot, when the rotating ring rotates, it will drive the first and second embedding rods to move inside the rotating ring and move upward together with the rotating ring. At this time, the fixing block will gradually move upward under the limit of the telescopic rod and no longer contact the insert plate. The insert plate loses the fixing force of the fixing block, and the second spring will pull the connecting rod, driving the insert plate to move out of the interior of the sealing cover. The sealing cover is no longer fixed by the insert plate. Under the push of the first spring, the bottom plate pushes the filter body upward and pushes it out of the housing. The purpose of quickly replacing and disassembling the filter body can be achieved without removing the housing from the installation position.

Detailed Implementation

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model. Example

[0026] A preferred embodiment of the filter with an easily removable filter element provided by this utility model is, for example... Figures 1 to 5 As shown: A filter with an easy-to-disassemble filter element includes a housing 1. A first spring 2 is fixedly connected to the bottom inner wall of the housing 1. A base plate 3 is fixedly connected to the top of the first spring 2. A filter element body 4 located inside the housing 1 is attached to the top of the base plate 3. A sealing cover 5 is rotatably connected to the side of the housing 1. A rotating ring 6 is threadedly connected to the surface of the housing 1. A groove 7 is provided inside the rotating ring 6. A first embedding rod 8 is slidably connected inside the groove 7. A second embedding rod 9, which is slidably connected to the rotating ring 6, is fixedly connected to one side of the first embedding rod 8. A fixing block 10 is fixedly connected to the top of the first embedding rod 8. A connecting plate 11, which is fixedly connected to the housing 1, is provided below the fixing block 10. A connecting rod 12 is slidably connected inside the connecting plate 11. An insert plate 13, which is embedded inside the sealing cover 5, is fixedly connected to the tail of the connecting rod 12. A second spring 14, which is fixedly connected to the connecting plate 11, is provided on one side of the insert plate 13.

[0027] In this embodiment, the filter element body 4 is in contact with the sealing cap 5, and the sealing cap 5 can hold the filter element body 4 against the inside of the outer shell 1.

[0028] In this embodiment, the slot 7 is arranged in a ring about the center of the rotating ring 6. By setting the slot 7, when the rotating ring 6 rotates, it will drive the first embedding rod 8 and the second embedding rod 9 to move inside the rotating ring 6 and move upward together with the rotating ring 6.

[0029] In this embodiment, the second embedding rod 9 is perpendicular to the first embedding rod 8. Both the second embedding rod 9 and the first embedding rod 8 are tightly fitted with the rotating ring 6, which can prevent the second embedding rod 9 and the first embedding rod 8 from shaking in the slot 7 when the rotating ring 6 moves.

[0030] In this embodiment, the insert plate 13 is tightly fitted to the sealing cover 5, and the connecting rod 12 forms a sliding structure inside the connecting plate 11 through the second spring 14. When the insert plate 13 is embedded inside the sealing cover 5, the sealing cover 5 can be fixed, thereby achieving the purpose of quickly assembling the sealing cover 5.

[0031] In this embodiment, the bottom of the fixed block 10 is connected to the outer shell 1 via a telescopic rod. The telescopic rod consists of two sets of vertical rods of different sizes that slide and fit together. The telescopic rod can limit the movement trajectory of the fixed block 10, enabling it to move horizontally up and down.

[0032] In this embodiment, when the insert plate 13 is embedded inside the sealing cover 5, it is located on the movement trajectory of the fixing block 10. The close surfaces of the insert plate 13 and the fixing block 10 are designed to be inclined. When the fixing block 10 descends, it will push the insert plate 13 to the side through the inclined surface, so that it is stably fixed inside the sealing cover 5. Example

[0033] Based on Embodiment 1, a preferred embodiment of the filter with an easily removable filter element provided by this utility model is, for example... Figures 1 to 5 As shown: A water inlet 15 is fixedly connected to the left side of the outer casing 1, a conduit 17 is fixedly connected to the bottom of the outer casing 1, a nozzle 18 is fixedly connected to the bottom of the conduit 17, a retaining ring 19 is fixedly connected to the surface of the nozzle 18, and an observation port 16 is fixedly connected to the surface of the outer casing 1.

[0034] In this embodiment, the conduit 17 is designed as a metal flexible hose. Since the conduit 17 is a metal flexible hose, the spray angle of the nozzle 18 can be adjusted when the nozzle 18 sprays water.

[0035] In this embodiment, the baffle ring 19 surrounds the nozzle 18, and the bottom of the baffle ring 19 is lower than the nozzle 18. By setting the baffle ring 19, the side of the nozzle 18 is surrounded, which can prevent water from splashing to the side when water is sprayed from the nozzle 18.

[0036] The working principle and usage process of this utility model are as follows: First, when it is necessary to disassemble and replace the filter element body 4, the rotating ring 6 can be controlled to rotate. At this time, the rotating ring 6 will rise along the outer shell 1. By setting the slot 7, when the rotating ring 6 rotates, it will drive the first embedding rod 8 and the second embedding rod 9 to move inside the rotating ring 6 and move upward together with the rotating ring 6. At this time, the fixing block 10 will gradually move upward under the limit of the telescopic rod and no longer contact the insert plate 13. The insert plate 13 loses the fixing force of the fixing block 10. The second spring 14 will pull the connecting rod 12, driving the insert plate 13 to move out of the interior of the sealing cover 5. The sealing cover 5 is no longer fixed by the insert plate 13. Under the pushing force of the first spring 2, the bottom plate 3 pushes the filter element body 4 upward and pushes it out of the interior of the outer shell 1. The purpose of quickly replacing and disassembling the filter element body 4 can be achieved without removing the outer shell 1 from the installation position.

[0037] By setting the conduit 17, which is a metal flexible tube, the spray angle of the nozzle 18 can be adjusted when spraying water. Furthermore, by setting the baffle ring 19, which wraps around the side of the nozzle 18, the problem of water splashing to the side when spraying water from the nozzle 18 can be avoided. The observation port 16 allows the user to see the condition of the filter body 4 from the outside and replace the filter body 4 as needed.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
