Emergency drinking water treater

Abstract

The invention discloses an emergency drinking water treater, belonging to the technical field of water treatment equipment. The emergency drinking water treater comprises a raw water bag, a one-way hand pump, an ultrafiltration filter and a water-producing water bag, wherein one end of the one-way hand pump is communicated with the raw water bag, and the other end is communicated with the ultrafiltration filter; the water-producing water bag is communicated with the ultrafiltration filter; the ultrafiltration filter comprises an ultrafiltration tank, a membrane sealing head and ultrafiltration membrane filaments; the membrane sealing head is fixed on the inner wall of the ultrafiltration tank and divides the inner cavity of the ultrafiltration tank into an upper cavity and a lower cavity; the ultrafiltration membrane filaments are arranged in the lower cavity and are of a filament shape; and a group of ultrafiltration membrane filaments is provided and forms a circular structure. The ultrafiltration membrane filaments are of a circular structure rand stay in a disturbance state, thus the moving property of the membrane filaments is improved, the scaling of the membrane surface is reduced, and the pollution and plugging of the membrane filaments are relieved; through a dead-end filtering way and without a concentrated water discharge port, the problems such as great change of membrane operation pressure can be relived; and without a pressure control valve, the structure is simpler and convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of water treatment equipment, and in particular relates to an emergency drinking water processor. Background technique [0002] Affected by environmental pollution and other factors, the current tap water, well water, river water, lake water, etc. are generally not suitable for direct drinking, which causes inconvenience to drinking water for field trips, expeditions, scientific research teams and military field soldiers. In order to reduce the burden, they can only carry bottled water, but due to the limited carrying capacity, it often cannot meet the rescue needs. Therefore, it is necessary for them to carry a portable manual drinking water processor to solve the above-mentioned drinking water problem by purifying the available surface water in the surrounding environment. [0003] Traditional portable manual drinking water processors mainly come in the following two forms: [0004] One is a drinking wat...

AI Technical Summary

Problems solved by technology

This structure is easy to produce dead angles for cleaning, which will damage and deform the membrane filaments, making disassembly difficult and difficult to clean.

[0006] It can be seen that the main problems of traditional drinking water processors suitable for personal use are: limited validity period, low water production, complex structure, cumbersome operation, and easy to cause membrane fouling
