The invention relates to the technical field of composite filter elements, in particular to an ultrafiltration composite filter element and water purification equipment. According to the ultrafiltration composite filter element provided by the invention, an inner shell is arranged to divide the inner space of an outer shell into a first filter element chamber and a second filter element chamber, a first filter element is arranged in the first filter element chamber, and a second filter element is arranged in the second filter element chamber, so that the parallel composite arrangement of the two filter elements is realized, and the overall volume of the ultrafiltration composite filter element is effectively reduced; and meanwhile, the first filter element and the second filter element are each provided with a water inlet, and the first filter element and the second filter element share or are each provided with a purified water outlet. The ultrafiltration composite filter element can be switched among three states, namely a water making state, a state that the first filter element backflushes the second filter element and a state that the second filter element backflushes the first filter element according to the conduction state of the water inlet and the water outlet, and the switching of the ultrafiltration composite filter element among the three states can be realized only by changing the conduction state of the water inlet and the water outlet. The structure is simple, operation is convenient, and the cleaning effect is good.
Description
technical field [0001] The invention relates to the technical field of composite filter elements, in particular to an ultrafiltration composite filter element and water purification equipment. Background technique [0002] With the improvement of people's quality of life, the use of water purifiers is becoming more and more popular. The application of ultrafiltration membranes in water purification systems can be used as pre-treatment filters or post-treatment filters. After three years without replacement, the application prospect is wide, so it is necessary to study the ultrafiltration membrane cleaning technology. In the prior art, the cleaning methods of ultrafiltration membranes include manual disassembly and cleaning and automatic cleaning. Among them, the method of manual disassembly and cleaning is cumbersome, which brings a lot of inconvenience to users; and the existing automatic cleaning technology of ultrafiltration membranes has many disadvantages. Among them, ...
