Description

Technical Field

[0001] This utility model belongs to the field of disc filter structure, specifically relating to an easy-to-clean and durable disc filter. Background Technology

[0002] Disc filter cartridges are commonly used filtration devices, widely employed in clarification filtration in pharmaceutical, food, and other fields. The typical filtration method involves placing the disc filter cartridge within a filter container, sealing one end (e.g., in contact with the top of the filter container). The fluid to be filtered enters the filter container and is positioned on the outside of the disc filter cartridge. Under pressure, it passes through the filter layer (being filtered simultaneously) and enters the fluid channel. The filtered fluid is then collected from the bottom of the fluid channel. However, current disc filter cartridges lack sufficient structural strength to guarantee long-term use and are difficult and cumbersome to clean. Summary of the Invention

[0018] Preferred embodiment.

[0019] This embodiment provides an easy-to-clean and durable disc filter element, including a first support column 100 and a plurality of first filter discs. The first filter discs are sleeved on the outside of the first support column 100. Each first filter disc includes a first support steel ring 230, a first inner filter screen 231 and a first outer filter screen 232. The first inner filter screen 231 and the first outer filter screen 232 are symmetrically arranged at both ends of the first support steel ring 230. The first outer filter screen 232 is arranged on the outside of the first inner filter screen 231. A first connecting component is provided in the middle of the first support steel ring 230, the first inner filter screen 231 and the first outer filter screen 232.

[0020] Furthermore, the first connecting assembly includes a first sleeve 210 and a second sleeve 220. The outer side of the first sleeve 210 is provided with a first external thread, and the inner side of the second sleeve 220 is provided with a first internal thread. The first internal thread matches the first external thread. The upper end of the first sleeve 210 is provided with a first limiting ring 211, and the lower end of the second sleeve 220 is provided with a second limiting ring 221. The first limiting ring 211 and the second limiting ring 221 match the first filter disc.

[0021] Furthermore, a plurality of first support washers 240 are fitted on the first support column 100, the first support washers 240 are disposed between the first filter discs, and the two ends of the first support washers 240 are provided with first sealing rings 241.

[0022] Furthermore, the inner side of the first limiting ring 211 is provided with a first limiting groove 212, the first support column 100 is provided with a plurality of first through holes 130, the first through holes 130 correspond one-to-one with the first limiting groove 212, the first support column 100 is provided with a first rotating shaft 110, the first rotating shaft 110 is provided with a plurality of first cams 120, the first through holes 130 are provided with a first limiting rod, the end of the first limiting rod near the first rotating shaft 110 is provided with a first limiting plate, the first limiting plate matches the first cam 120, and a first spring is sleeved on the first limiting rod, the first spring corresponding between the first limiting plate and the first support column 100.

[0023] Furthermore, the lower end of the first support column 100 is provided with a first plug 140, the upper end of the first plug 140 is provided with a second external thread, and the lower end of the first support column 100 is provided with a second internal thread, the second internal thread matching the second external thread.

[0024] Working principle: The first inner filter screen 231 is placed at both ends of the first support steel ring 230, and the first outer filter screen 232 is placed at both ends of the ring. This is then fitted onto the second sleeve 220 and fixed to the first sleeve 210 using the first internal and first external threads. This connects the first sleeve 210 and the second sleeve 220 together, fixing the first inner filter screen 231 and the first outer filter screen 232 to form the first filter disc. The first filter disc is fitted onto the first support column 100, and the first support washer 240 is placed between the first filter discs. The first support washer 240 has first sealing rings 241 at both ends, making the connection of the first filter discs more stable. When lowering the first filter disc, the first through hole 130 is aligned with the first limiting groove 212. Finally, the first rotating shaft 110 is rotated, causing the first cam 120 to press against the first limiting plate. This pushes the first limiting rod out of the first through hole 130 and into the first limiting groove 212, thereby fixing and restricting the first filter disc. Finally, the first plug 140 is connected and fixed to the first support column 100 using the second external thread and the second internal thread to ensure the sealing of the first support column 100.

[0025] The first through hole 130 is aligned with the first limiting groove 212. This alignment can be achieved by setting micro-grooves and micro-protrusions as limiting methods. The rotation of the first rotating shaft 110 can also be achieved by conventional technical means.

[0026] It is worth mentioning that the technical features of the first inner filter and the first outer filter involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and possible control methods and spatial arrangement of these technical features can be adopted by conventional choices in the field, and should not be regarded as the utility model point of this utility model patent. This utility model patent will not be further elaborated in detail.

[0027] For those skilled in the art, modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
