The invention relates to a portable environment-friendly purifying device, wherein a flow disturbing and pressure operation structure is designed, through rotating a water filtering pipeline (2) by arotating motor (8), and combining the limitation of a guiding bar (6) to the horizontal rotation of a disturbance plate (5), the disturbance plate (5) can move up and down along the water filtering pipeline (2), based on the downward movement of the disturbance plate (5), the pressure operation on water is realized, the water is sent to the water filtering pipeline (2) through an opening end at the bottom of the water filtering pipeline (2), and then is filtered through a specified filter element device (3) and a ultrafiltration membrane (4), meanwhile, the centrifugal movement is realized through the rotating of the water filtering pipeline (2), so that water in a centrifuging region (15) can be output through a hollow strusture and reflow to a main bottle body (1), at the same time, theup and down movement of the disturbance plate (5) can accelerate the full mixing of filtered water; for the water in the main bottle body (1), the repeated circulating between the bottle and a water filtering device is realized, and the circulating and purifying of water in the main bottle body (1) are realized.

A filling strainer pipe comprises a longitudinally arranged strainer pipe body and a steel wire rope, wherein the steel wire rope is located inside the strainer pipe body, the upper end and lower end of the strainer pipe body are respectively provided with a steel wire rope clip and a chuck in sequence, and a limiter is arranged inside the strainer pipe body; each chuck comprises a first limiting ring and an upper supporting ring; the limiter comprises a second limiting ring and a third limiting ring, and the steel wire rope penetrates through the first limiting ring and the upper supporting ring of the chuck at the upper end of the strainer pipe body, the second limiting ring and the third limiting ring of the limiter, and the upper supporting ring and the first limiting ring of the chuck at the lower end of the strainer pipe body in sequence; the upper end of the steel wire rope is clamped through the steel wire rope clip at the upper end of the strainer pipe body, and the lower end of the steel wire rope is clamped through the steel wire rope clip at the lower end of the strainer pipe body. The filling strainer pipe is simple in structure, convenient and quick to install, high in safety performance, long in service life, low in cost, and good in water filtration effect.

The invention relates to a cellulose-based transparent waterproof film with high shape stability and a preparation method thereof. The pretreated nano-plant fibers are modified by ion exchange, and mixed with micron-scale plant fibers to strengthen the three-dimensional network structure. And produce repulsion to water molecules, so that the moisture resistance of the film is significantly improved. The present invention solves the conflicting problem of superhydrophobicity and light transmittance on the surface of the film through the selection of adhesives, and not only ensures superhydrophobicity, but also has excellent visible light transmittance. For the first time, the invention achieves the shape stability of the film under high humidity conditions through the synergistic effect of the water-resistant and anti-plasticization treatment inside the film and the hydroxyl masking treatment on the surface. The film can not only resist the plasticization of small-volume liquid and gas water molecules, but also Prevent the penetration of large droplets; secondly, introduce an adhesive to realize the effective adhesion of low surface energy substances on the cellulose film substrate, ensure the superhydrophobicity and high visible light transmittance of the film, and greatly improve the dimensional stability of the film .

The invention discloses a zinc and nickel impregnation agent pulp washing filtered water recycling device. The zinc and nickel impregnation agent pulp washing filtered water recycling device is characterized in that a framework is arranged in a clear water basin and comprises an upper framework seat, a lower framework seat and a plurality of guiding upright columns, and an upper sliding plate and a lower sliding plate are disposed between the upper framework seat and the lower framework seat, are sleeved on the guiding upright columns and can slide up and down; through holes are arranged on the upper sliding plate and the lower sliding plate and are in one-to-one correspondence with one another, a filter bag is arranged in each through hole of the upper sliding plate, and frames are arranged in the filter bags; each frame comprises an upper flange at the upper end of the frame, a frame seat at the lower end of the frame and a plurality of filter bag support rods arranged between the upper flange and the frame seat; a slurry tank is arranged on the upper sliding plate, an output shaft of an electric elevator is connected with the bottom of the slurry tank; sliding dry columns are disposed on the lower framework seat, and upper ends of the sliding dry columns extend into the filter bags and are connected with mud core supporting plates. A filtering method is adopted for impregnation agent pulp washing dewatering, and is free of energy consumption. Besides, the filtering area is greatly increased owing to the multiple filter bags, and water filtration efficiency is improved. In addition, impregnation agent mud cores can be separated from the filter bags easily, recycling is facilitated, the filter bags can be cleaned automatically, and a good water filtration function is kept.

The invention discloses a ditch anti-blocking recharge filtering device, and belongs to the technical field of aquifer recharge, namely groundwater artificial recharge. The ditch anti-blocking recharge filtering device comprises a ditch, a labyrinth weir structure, a sloping plate filter structure and a dredging well, and the labyrinth weir structure is laid on a ditch slope, and comprises a plurality of labyrinth weir monomers; each labyrinth weir monomer comprises filter plates I and filter plates II, and the filter plates I and the filter plates II are each provided with a plurality of water inlets; the filter plates I, the filter plates II and the ditch slope enclose and form a water storage cavity, and the water storage cavity is vertically formed along the ditch slope; and one end ofthe sloping plate filter structure communicates with the labyrinth weir structure, and the end, far away from the labyrinth weir structure, of the sloping plate filter structure communicates with thedredging well through a collector pipe which is provided with a plurality of drain holes. According to the ditch anti-blocking recharge filtering device, the area of a river channel is not occupied,and water flow is not affected; and the filtering device is prevented from being blocked by sediments, and the filtering efficiency is improved.
