Material-pumping tube, the material-pumping tube stretch into liquid reserve tank through device body outside, and the liquid reserve tank bottom is provided with filter membrane, the mistake
Filter membrane bottom is provided with storage tank, and the storage tank bottom is provided with waste outlet, and the separating pipe bottom is provided with waste pipe,
The waste pipe arrives at waste outlet through liquid reserve tank, and liquid reserve tank bottom side is provided with dirt-discherging outlet, the liquid reserve tank one
Side upper end is provided with feed pipe, and described device outer body bottom is provided with support.
Preferably, the filter membrane is milipore filter.
Preferably, the feed pipe, dirt-discherging outlet and material-pumping tube side are mounted on sealing valve.
Preferably, dividing plate inside the liquid reserve tank and only, the dividing plate upside are provided with multiple bellmouths.
Preferably, described device body side is provided with booster pump, and the booster pump side is connected by conduit and liquid reserve tank
Connect.
Compared with prior art, the beneficial effects of the utility model are：The milipore filter that the utility model filter membrane uses can
With when stoste flows through film surface, the densely covered many tiny micropores of ultrafiltration membrane surface only allow water and small-molecule substance by and
As permeate, and volume is then trapped within the liquid feeding side of film more than the material in film surface micropore footpath in stoste, turns into concentrate,
Effectively water can be removed, booster pump can carry out increase pressure to liquid reserve tank inside so that filter membrane both ends produce
Pressure differential, accelerate the rate of filtration, because liquid reserve tank internal pressure is larger, weight can sink, can be effectively by weight by dividing plate
Thing is isolated, and bellmouth is designed to reduce weight floating area, sealing in the case where not reducing weight area of subsidence
Valve can make liquid reserve tank be sealing structure, prevent ambient pressure from entering.
