Description

Technical Field

[0001] The utility model relates to the field of filters, in particular to a multi-media filter that is easy to replace materials. Background Technique

[0002] A multi-media filter is a device that uses more than two kinds of filter media for water treatment. Under a certain pressure, it can make water with a higher turbidity pass through a certain thickness of granular or non-granular materials, thereby effectively removing suspended impurities and clarifying the water. Its commonly used filter materials include quartz sand, anthracite, manganese sand, etc., and there are also activated carbon, fiber balls, silica sand, ceramsite, etc. These media have different particle sizes and densities, forming a filtering hierarchical structure. For example, the multi-media filter with the application number CN202320156598.8 specifically discloses including a base, a fixing frame is fixedly installed at the upper end of the base, a filtering device body is fixedly installed through the upper end of the fixing frame, a rectangular through hole is opened through the upper end of the base, a servo motor is fixedly installed at the front end of the base, a rotating rod is fixedly installed at the left end of the servo motor through an output shaft, and a first bevel gear is fixedly installed at both the right and left sections of the rotating rod. Through the lifting mechanism and the connecting rod mechanism provided by the utility model, the filtering device body can contact the ground with the bottom support plate under the rotation of the two connecting rods, and the filtering device body can be lifted upward. The filtering device body can move under the action of four pulleys at the lower end of the bottom support plate.

[0003] During the use of the existing multi-media filter, due to the blockage inside the filter or the loss of the filter media inside the filter with the increase of the use time, it is necessary to replace the filter.
