Description

Filter element structure with completely clean back washing

Technical Field

The utility model relates to a filter element structure design, in particular to a filter element structure which is driven by a flow disturbing unit to generate local whirl water flow, namely, a back pressure effect, and assist the back water flow to the head end of a filter unit.

Background

After a period of time of use, the conventional commercial water purifier has a reduced water filtering efficiency because the gaps between the mesh openings of the filter material in the filter element are filled with the attached particulate deposits, so that the filter material needs to be removed and cleaned regularly or replaced with new products, which is relatively troublesome to use and maintain and does not meet the economic benefit.

In order to overcome the disadvantages of the water purifier, a new water purifying product is developed in the industry, such as a manual cleaning and switching device for a filter element of a water purifier in taiwan patent publication No. M474561, and the technical means of the patent achieves the effects that a water inlet is communicated with a filter cartridge in a normal state, raw water is input into each filter cartridge by a pipe body for filtration, and purified water is output for use by the pipe body connected with a water outlet; if the filter element is to be cleaned, the switching valve on one side is shifted to close the water inlet hole to conduct the water outlet hole, purified water filtered by the filter element on the other side flows into the filter cylinder on the side to be backwashed, and backwashed sewage is discharged from the pipe body of the water outlet hole, namely backwashed is carried out by changing the water flow direction, so-called backwashed cleaning.

The technical means of the patent improves the trouble that the common water purifier needs to frequently replace the filter element, prolongs the service life of the filter element and does not need to consume electric power, but in the general backwashing process, the tail end of the filter element is easy to wash cleanly because of bearing the larger hydraulic impact force of backwash water flow, but when the larger hydraulic impact force is used for impacting and removing the impurities of the filter element, the sieve holes of the filter element are penetrated by water flow and the backwash water pressure of the filter material is relieved, the water flow flowing through the head end of the filter element can flow through the surface of the filter material rapidly, and the backwash water flow cannot effectively penetrate the sieve holes of the filter material, so that the poor backwashing cleanly effect is caused, namely, the head end of the filter element cannot be fully backwashed cleanly because of the smaller hydraulic impact force, weak backwashing and poor backwashing cleanliness reduction in the backwashing process. Therefore, the back washing effect of the filter element is not ideal due to the structure of the filter element, and there is room for improvement.

In view of the above, the present inventors have developed the present utility model based on the idea of continuous product research and innovation, based on practical experience of product design and development for many years, and actively and intensively developing and thinking, through numerous practical tests and experiments.
