Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, and in particular to a granular activated carbon filter element. Background Technology

[0002] With the continuous development of water treatment technology, granular activated carbon filter cartridges are widely used in drinking water purification, industrial wastewater treatment and other fields due to their excellent adsorption performance.

[0003] Conventional filter cartridges lack effective pressure regulation devices, making them prone to leakage or even structural damage when water pressure fluctuates significantly. In addition, most filter cartridges are fixed by flange thread connections, which are inconvenient to install and disassemble, increasing maintenance difficulty and cost. To solve the above problems, this utility model provides a granular activated carbon filter cartridge. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a granular activated carbon filter element.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A granular activated carbon filter element includes a filter element body, a first reducing pipe, a second reducing pipe, and a fixing assembly. An upper connecting pipe is fixedly connected to the upper end of the filter element body, and a lower connecting pipe is fixedly connected to the lower end of the filter element body. A first connecting disc is fixedly connected to the opposite ends of both the upper and lower connecting pipes. A second connecting disc is fixedly connected to the opposite ends of both the first and second reducing pipes. The fixing assembly includes a first fixing ring, and a second fixing ring is rotatably connected to one side of the first fixing ring via a hinge. Both the first and second fixing rings have internal locking grooves adapted to the first and second connecting discs. A protective assembly is fixedly connected to the surface of the first reducing pipe.

[0007] As a further improvement of this utility model, the protective component includes an adjusting pipe fixedly connected to the surface of the first reducing pipe, an adjusting piston movably connected inside the adjusting pipe, the adjusting piston and the adjusting pipe being in a sealing sliding fit, a pressure spring fixedly connected to the upper end of the adjusting piston, a fixing seat fixedly connected to the upper end of the adjusting pipe, the upper end of the pressure spring fixedly connected to the fixing seat, and a pressure relief pipe provided on one side of the surface of the adjusting pipe.

[0008] As a further improvement of this utility model, a sleeve rod is fixedly connected to the middle of the lower surface of the fixed seat, and a guide rod is fixedly connected to the middle of the upper surface of the adjusting piston.

[0009] As a further improvement of this utility model, the guide rod is movably connected to the sleeve rod, and both the sleeve rod and the guide rod are located inside the pressure spring.

[0010] As a further improvement of this utility model, a connecting block is fixedly connected to the front of both the first fixing ring and the second fixing ring. One of the connecting blocks has a first threaded hole on one side, and the other connecting block has a first through hole on one side. A fixing bolt that matches the first threaded hole is inserted into the first through hole, and a knob is fixedly connected to one end of the fixing bolt.

[0011] As a further improvement of this utility model, the upper end of the first reducing pipe is fixedly connected to a water inlet pipe, the lower end of the second reducing pipe is fixedly connected to a water outlet pipe, and a sealing gasket is provided at the opposite end of the first connecting plate and the second connecting plate.

[0012] The beneficial effects of this utility model are:

[0013] By setting up a fixing component, the first and second fixing rings are hinged during use. Combined with the tight fit between the snap-fit ​​groove and the connecting plate, the filter element can be quickly installed and removed, improving maintenance efficiency. At the same time, the first and second fixing rings are locked together by the connecting block and fixing bolts to ensure a stable connection and prevent loosening or leakage caused by water flow impact. This not only enhances the sealing performance but also adapts to different pipe connection specifications, improving the versatility and reliability of the filter element.

[0014] By incorporating protective components, the system effectively addresses water pressure fluctuations through the coordinated action of the regulating pipe, regulating piston, and pressure spring. When the water pressure is too high, the regulating piston moves upward under pressure, compressing the spring and releasing excess pressure through the pressure relief pipe, preventing the filter element from being damaged by overpressure. Once the pressure returns to normal, the spring pushes the piston back to its original position, maintaining stable system operation. At the same time, the design of the sleeve rod and guide rod ensures smooth piston movement, preventing skewness or jamming, thereby extending the filter element's service life and improving safety performance.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-3 A granular activated carbon filter element includes a filter element body 1, a first reducing pipe 2, a second reducing pipe 3, and a fixing assembly. An upper connecting pipe 4 is fixedly connected to the upper end of the filter element body 1, and a lower connecting pipe 5 is fixedly connected to the lower end of the filter element body 1. A first connecting disc 6 is fixedly connected to the opposite ends of the upper connecting pipe 4 and the lower connecting pipe 5. A second connecting disc 7 is fixedly connected to the opposite ends of the first reducing pipe 2 and the second reducing pipe 3. The fixing assembly includes a first fixing ring 8. A second fixing ring 9 is rotatably connected to one side of the first fixing ring 8 via a hinge. The interior of both the first fixing ring 8 and the second fixing ring 9 is provided with a snap-fit ​​groove 10 that matches the first connecting disc 6 and the second connecting disc 7. A protective assembly is fixedly connected to the surface of the first reducing pipe 2.

[0021] In this invention, the protective component includes an adjusting pipe 11 fixedly connected to the surface of the first reducing pipe 2. An adjusting piston 12 is movably connected inside the adjusting pipe 11. The adjusting piston 12 and the adjusting pipe 11 are in a sealed sliding fit, and a sealing ring is used to seal between them to ensure that the water inside the adjusting pipe 11 will not leak during the sliding of the adjusting piston 12, thus ensuring the normal operation of the protective component. A pressure spring 13 is fixedly connected to the upper end of the adjusting piston 12. The pressure spring 13 has good elasticity and recovery performance, and can deform under pressure and return to its original shape after the pressure is removed. A fixing seat 14 is fixedly connected to the upper end of the adjusting pipe 11, and the upper end of the pressure spring 13 is fixedly connected to the fixing seat 14. A pressure relief pipe 15 is provided on one side of the surface of the adjusting pipe 11. When the internal pressure of the adjusting pipe 11 exceeds a certain limit, the excess pressure can be released through the pressure relief pipe 15 to prevent damage to the filter element and related components due to excessive pressure.

[0022] A sleeve rod 16 is fixedly connected to the middle of the lower surface of the fixed base 14. The sleeve rod 16 is a hollow cylindrical structure, which provides guidance and restriction for the movement of the guide rod 17. A guide rod 17 is fixedly connected to the middle of the upper surface of the adjusting piston 12. The guide rod 17 is a solid cylindrical structure, which works in conjunction with the sleeve rod 16 to ensure the linearity of the movement of the adjusting piston 12 within the adjusting tube 11. The guide rod 17 is movably connected to the sleeve rod 16. Both the sleeve rod 16 and the guide rod 17 are located within the pressure spring 13, so that the pressure spring 13 can move along the direction of the sleeve rod 16 and the guide rod 17 during compression and extension, thus preventing the pressure spring 13 from bending and deforming, which would affect its performance and service life.

[0023] Both the first fixing ring 8 and the second fixing ring 9 are fixedly connected to a connecting block 18 on their front sides. The connecting block 18 is a rectangular block structure, providing a connection point for the subsequent installation of the fixing bolt 19. One of the connecting blocks 18 has a first threaded hole on one side, and the other connecting block 18 has a first through hole on one side. A fixing bolt 19 that matches the first threaded hole is inserted into the first through hole. The fixing bolt 19 can be inserted into the first through hole and screwed into the first threaded hole. Through the engagement of the threads, the two connecting blocks 18 are tightly connected together, thereby fixing the first fixing ring 8 and the second fixing ring 9. A knob 23 is fixedly connected to one end of a fixing bolt 19, allowing operators to manually rotate the fixing bolt 19 for installation and disassembly. An inlet pipe 20 is fixedly connected to the upper end of the first reducing pipe 2, and an outlet pipe 21 is fixedly connected to the lower end of the second reducing pipe 3. Sealing gaskets 22 are provided at opposite ends of the first connecting plate 6 and the second connecting plate 7. The sealing gaskets 22 are made of rubber material. When the first connecting plate 6 and the second connecting plate 7 are in contact, the sealing gaskets 22 can provide a good seal, preventing water from leaking from the connection and ensuring the normal operation and performance of the filter element.

[0024] In use, the upper connecting pipe 4 at the upper end and the lower connecting pipe 5 at the lower end of the filter element body 1 are first connected to the first reducing pipe 2 and the second reducing pipe 3 respectively. The first connecting plate 6 at the opposite end of the upper connecting pipe 4 and the lower connecting pipe 5 is fitted with the second connecting plate 7 at the opposite end of the first reducing pipe 2 and the second reducing pipe 3. The sealing gasket 22 set at the opposite end of the first connecting plate 6 and the second connecting plate 7 plays a sealing role to prevent water leakage. Then, the fixing components are used for fixing. The first fixing ring 8 and the second fixing ring 9 are opened by rotating the hinge so that the first connecting plate 6 and the second connecting plate 7 are placed in the snap-fit ​​groove 10 opened inside the first fixing ring 8 and the second fixing ring 9. Then, the fixing bolt 19 is passed through the first through hole on one of the connecting blocks 18 and screwed into the first threaded hole on the other connecting block 18. Then, the knob 23 is turned to tighten the fixing bolt 19 to realize the fixed connection of the first fixing ring 8 and the second fixing ring 9, thereby fixing the first connecting plate 6 and the second connecting plate 7 together and completing the connection between the filter element body 1 and the first reducing pipe 2 and the second reducing pipe 3.

[0025] At this time, the inlet pipe 20 at the upper end of the first reducing pipe 2 is used to connect the water to be filtered. The water flows through the first reducing pipe 2 into the filter element body 1 for filtration. The filtered water flows out from the lower connecting pipe 5 through the second reducing pipe 3 and then out from the outlet pipe 21 at the lower end of the second reducing pipe 3. When the water pressure changes, the adjusting piston 12 in the protective assembly on the surface of the first reducing pipe 2 will slide in the adjusting pipe 11. If the pressure increases, the adjusting piston 12 compresses the pressure spring 13 and moves upward. The guide rod 17 moves in the sleeve rod 16 and guides the movement of the adjusting piston 12 to ensure the stability of the movement of the adjusting piston 12. When the pressure is too high, the pressure relief pipe 15 on the surface of the adjusting pipe 11 can release the pressure to prevent the filter element from being damaged due to excessive pressure. When the pressure returns to normal, the pressure spring 13 resets and pushes the adjusting piston 12 downward to return to its original position.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
