Hollow fiber ultrafiltration membrane and PP combined filter core

Abstract

The invention discloses a hollow fiber ultrafiltration membrane and PP combined filter core, and relates to the field of ultrafiltration membrane filter cores. The hollow fiber ultrafiltration membrane and PP combined filter core comprises a filter, wherein a first flange pipe is arranged at the top end of the filter, a second flange pipe is arranged at the bottom end of the filter, a filter flange disc is arranged on the outer wall of the filter, the top end, located above the filter flange disc, of the filter is connected with a water inlet pipe, flange holes are formed in the outer portionsof the filter, the first flange pipe and the filter flange disc, the flange holes are provided with matched fixing bolts, and the fixing bolts are provided with matched fixing nuts. By arranging theconnecting disc, the limiting rod, the rotating column and the like, the situation that the using effect and the filtering effect of the filter are affected due to the fact that water flow entering the filter from the direction of the first flange pipe is too large and impact force is too strong is avoided, and the filter below is prevented from being damaged or destroyed by the water flow, so that the use safety of the filter is protected and the service life is prolonged.

Description

technical field [0001] The invention relates to the field of ultrafiltration membrane filter elements, in particular to a hollow fiber ultrafiltration membrane and PP combined filter element. Background technique [0002] Hollow fiber ultrafiltration membrane is a kind of ultrafiltration membrane, which is the most mature and advanced technology in ultrafiltration technology. Because the hollow fiber tube wall is full of micropores, the molecular weight of the pore size can intercept the substance is relatively large, and the molecular weight interception can reach several thousand to hundreds of thousands. When the raw water flows under pressure on the outside of the hollow fiber or in the inner cavity, the external pressure type and the internal pressure type are respectively formed. This ultrafiltration dynamic filtration process can remove the intercepted substances along with the concentrated water, without clogging the membrane surface and long-term continuous operatio...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a hollow fiber ultrafiltration membrane and PP composite filter element in order to solve the problems that the current filter elements in the market do not have the cleaning function and are complicated to install during use, and do not have the function of buffering the water flow.
