Embodiment 1

[0071] In this embodiment, the above-mentioned water purifier is used to purify the raw water, and the cross-sectional area of ​​the piston 15 is 2 cm. 2 , then under the force of 40N, the working pressure provided by the water inlet cylinder 14 is 0.2 MPa, which meets the osmotic pressure required for the normal operation of ultrafiltration. In filler 23, volume of activated carbon: volume of chitosan=3:1, activated carbon is coconut shell activated carbon, mesh number 20-40 mesh, chitosan filler 18-30 mesh, total volume of filler 23 is 200mL. Filter screen 27 meshes are less than 10 meshes. Ultrafiltration membrane module 25 adopts microfiltration membrane with a pore size of 10-30nm, operating pressure: 0.1-0.2MPa, and designed membrane flux: 25L / m 2 h, membrane service life ≥ 5 years, membrane strength > 200N / monofilament. The estimated membrane area used is 1m 2 , the design water flow rate is about 400ml / min, and the filter membrane is a cylinder of Φ2.5cm*15cm.

Abstract

The invention discloses a portable water purifier and water purifying, back washing and packing replacing methods and belongs to drinking water treatment. The portable water purifier comprises a water drawing part and a filtering part; the water drawing part comprises a feedwater barrel, and an inner thread is arranged in the lower end of the feedwater barrel; the filtering part comprises a packing barrel opened in two ends, each of two ends of the packing barrel is provided with a double-end stud, and one of the double-end studs is matched with the inner thread of the feedwater barrel while the other one is connected with a tail hood with a water outlet. By the arrangement, structure of the packing barrel is purified, packing can be backwashed on the basis of meeting requirements of water purification, change frequency of the packing is lowered, service time of the packing is prolonged, utilization rate of the packing is increased, and replacement of the packing is much easier; with the method, sewage can be purified to drinking water standards by the aid of the water purifier; washing of the packing of the water purifier can be realized through the back washing method, and service time of the packing is prolonged; the packing can be easily and rapidly replaced with the packing replacing method.

Description

technical field [0001] The invention belongs to the technical field of water purifiers, and relates to a portable water purifier with reusable filter material and convenient replacement, more specifically, a portable water purifier and its water purification, backwashing and packing Replacement method. Background technique [0002] In activities such as underground mining, camping, outdoor tourism, and individual combat, people need to take sufficient and effective drinking water safety measures. If you carry drinking water directly, it will increase the travel burden. At present, the more common way is to use an outdoor water purifier to purify the natural water source and drink it directly. Outdoor water purifiers use natural water such as streams, rivers, lakes, and rainwater as water sources. Through filtration or disinfection, pathogenic bacteria in the water are filtered out or killed to obtain safe drinking water. When the outdoor water purifier is used, only manpow...
