Description

Automatic cleaning device for ceramic filter elements

technical field

The utility model relates to a ceramic filter core, in particular to an automatic cleaning device for the ceramic filter core.

Background technique

Ceramic filter element is mainly used for filtering, antibacterial and activation treatment of drinking water, harmful residual chlorine and suspended pollutants, organic chemical substances, color and peculiar smell, through the use of this filter element can filter out drinking water that meets a certain drinking standard. It can be used not only in industries such as water purifiers, bottled water, and water supply by quality, but also in other occasions that have corresponding requirements for water quality. The water filtered by the ceramic filter element can reach the standard of direct drinking water without boiling.

However, when ceramic filter elements are used in water purifiers and functional water machines, in the process of purifying water, dirt can be trapped on the surface of the filter element, which can easily cause blockage and make the water flow drop quickly. Generally, it needs to be manually disassembled and cleaned at least once every 0.5 to 1 month. The common practice is to disassemble the entire water purifier and functional water machine after the surface of the ceramic filter element is clogged, then manually clean it, and then install it back. However, both disassembly and installation require certain professional skills, and it is difficult for ordinary users to disassemble and assemble during cleaning; and in the process of manual cleaning, due to the uneven force applied, it is easy to damage the ceramic filter element during brushing; in addition , Due to frequent disassembly and assembly, it is easy to cause the seal of the ceramic filter element to be worn. If the sealing effect is reduced, water leakage will occur, and the water filtration effect cannot be achieved, and professional skills are required to ensure a certain degree of sealing during installation.

The rings attract each other across the cylinder wall. Push and rotate the outer magnetic ring by hand, the inner magnetic ring will be moved synchronously and drive the scrubbing assembly to scrub the ceramic filter element.

The above-mentioned device for cleaning the ceramic filter element in the water purifier does not need to disassemble the shell cylinder during cleaning, and it also avoids possible damage to the components during frequent washing and disassembly, but it still needs to be cleaned every time. Manual operation is required, and the uniformity of scrubbing during cleaning cannot be guaranteed, which may cause damage to the ceramic filter element, and it is a waste of manpower, and the cleaning efficiency is low, and further improvement is still needed.
