Embodiment
Below by specific embodiment, the utility model is described in further detail, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A kind of rotation immersion water treatment ultramicro filtration device, comprises some bundle film silks 3, film wire tray 2,4, assembly chassis 1, water leg 5, tubular shaft 6, bearing support 7 and drainage by suction pipe 10.The two ends of often restrainting film silk are all cast in upper and lower film wire tray, be positioned at that the film wire tray 2 (shutoff of silk hole) of lower end is uniform to be fixed on assembly chassis 1, the film wire tray 4 being positioned at upper end seals the uniform hole week being fixed on water leg 5 lower surface, and film silk hole communicates with water leg 5 inner chamber.Water leg 5 and tubular shaft 6 Flange joint, the snap ring 9 on tubular shaft 6 is arranged on the bearing 8 in bearing support 7, can bear weight and the rotation of membrane module.The flange of drainage by suction pipe 10 and bearing support 7 Flange joint, make water leg 5, tubular shaft 6, drainage by suction pipe 10 form a drainage channel, discharges the water after purification.
In order to reduce the pollution efficiency of film silk, film silk mode of motion can be adopted to realize, membrane module is such as made to rotate, the application recommends a kind of implementation: be fixedly mounted with a circle engaging pin gear 14 at water leg upper surface excircle, be fixedly mounted with a pinion(gear) 13 in the outer rim of pin gear, pinion(gear) and transmission shaft 12 are packed in the output shaft end of step-down gear 11.The step-down gear of translator makes membrane module do positive and negative rotation motion, and the state making film silk be in motion is purified waste water, and ensure film silk surface non-scaling, net water flux is unattenuated.
In order to increase the anchorage force of upper and lower film wire tray, making membrane module in aggregates, between water leg and assembly chassis, being evenly fixedly mounted with one group of support link (what adopt in figure is three, left, center, right connecting rods).
Above-mentioned membrane module outside no longer arranges film pipe, makes film silk be in a kind of unlimited state, direct contact flow be filtered water body.Adopt drive unit to make membrane module carry out positive and negative rotation motion in processed water, current and film silk generation Relative friction in motion, because film silk surface is subject to the scouring force (tangential force) of current, in time the dirt on film silk surface is taken away.
The working method rotating immersion water treatment ultramicro filtration device in the application is:
Be fixed on the platform for the treatment of tank by whole device, wastewater level controls below water leg 1/2 thickness, and after starter motor, step-down gear is started working, and drives membrane module to rotate.Employing pump takes out or the mode of siphon realizes negative pressure, and forced water is through film silk surface, and enter in film silk, be upwards collected in water leg, the water after purification is discharged collection by tubular shaft, drainage by suction pipe, or enters in next stage treating plant.
The controlled membrane module positive and negative rotation of drive unit, water leg outer rim linear speed is 0.5m/s ~ 1m/s.
In the motion of membrane module, due to inertia effect, velocity contrast is there is between current and film silk, make both that relative movement occur, film silk and current generation Relative friction, this current scour power makes the dirt of film surface attachment be taken away in time, effectively prevents the blocking of film, filtering traffic is not decayed, improves filtration efficiency.
