Efficient multifunctional water purification filter

Abstract

The invention discloses an efficient multifunctional water purification filter which is provided with a shell, wherein the shell is provided with a water inlet and a water outlet; the top in the shell is provided with a water feeding cavity; the water feeding cavity is connected with the water inlet; the bottom in the shell is provided with a water collection cavity; the center of the shell is vertically provided with a central filtering body; the central filtering body is provided with a central pipe body; the inner cavity of the central pipe body forms an inner-layer runner; the bottom of the inner-layer runner is communicated with the water collection cavity; the top of the inner-layer runner is connected with the water outlet on the shell; center filter material is filled in the inner-layer runner; an outer-layer runner is formed between the central filtering body and the inner wall of the shell; the outer-layer runner is divided into continuous spiral filtering paths by a spiral diaphragm; the continuous spiral filtering paths go upwards and are communicated with a water feeding chamber and are downwards communicated with a water collection chamber; and outer layer filter material is filled in the continuous spiral filtering paths. The efficient multifunctional water purification filter has a longer flow path, can continuously perform the action of filter material, service life is prolonged, cost can be saved, the performance of the filter material is improved and filtering effect is enhanced.

Description

technical field [0001] The invention relates to a filtering device, in particular to a high-efficiency multifunctional water purification filter. Background technique [0002] Ordinary water purification filters usually use sediments, sedimentary materials such as hollow fibers, or carbon-like adsorptive materials to purify water purification filters, and water purification filters that use osmotic pressure to operate device. [0003] The raw materials inside these water purifying filters are granular or porous honeycomb, and the multiple pores are used to purify water by precipitation or adsorption. [0004] However, if we observe the flow direction of water inside the filter, it is not difficult to find that if the filter is made of granular materials, the water injected into the filter will flow from top to bottom or from bottom to top. When filtering in a dispersed state, the injected water will flow out from the outside to the inside or from the inside to the outside...
