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 40 N, 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 relates to a portable water purifier and methods for water purification, backwashing and filler replacement thereof, belonging to the field of drinking water treatment. The portable water purifier includes a water-drawing part and a filter part; the water-drawing part includes a water inlet cylinder, and the lower end of the water inlet cylinder has internal threads; the filter part includes a stuffing tube with two ends open, and a stud is installed at both ends of the stuffing tube , one of the studs is matched with the internal thread of the water inlet cylinder, and the other stud is connected to the tail cap with the water outlet. The water purifier of the present invention optimizes the structure of the packing cylinder. Under the premise of meeting the water purification requirements, the packing can be backwashed, the replacement frequency of the packing is reduced, the use time of the packing is prolonged, the utilization rate of the packing is improved, and the replacement of the packing is easier. The water purification method adopts a water purifier to purify the sewage to the standard of drinking water; the backwashing method can realize the flushing of the filler of the water purifier, prolonging the use time of the filler; the replacement method of the filler can simply and quickly replace the filler.

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...
