Brief description of the drawings
Fig. 1 is schematic diagram of the invention.
Specific embodiment
As shown in figure 1, a kind of underground mine use special type ultralow pressure nanofiltration water purifier, including fore filter 2, prefilter
The water inlet of device 2 is connected with water source by water inlet pipe, and its delivery port is connected with the water inlet of PP cotton filter cores 4 by water pipe, PP cottons
The delivery port of filter core 4 is connected with the water inlet of ultrafiltration membrane filter element 5 by water pipe, delivery port I and the nanofiltration core 7 of ultrafiltration membrane filter element 5
Water inlet by water pipe connect, on the delivery port I of nanofiltration core 7 connect nanofiltration water outlet pipe, set on nanofiltration water outlet pipe
Put water purification valve 9；
After the water of conveyance conduit enters nanofiltration water purifier in mine, fore filter 2, PP cotton filter cores 4, ultrafiltration membrane filtration are passed sequentially through
Core 5, nanofiltration core 7, it is the impurity gone in water removal, macromolecular particle, silt, iron rust, suspension, bacterium, virus, heavy metal, organic
Thing, can retain the mineral matter beneficial to human body, form nanofiltration water, be drunk for construction worker.
Milipore filter wash tub pipe is connected on the delivery port II of ultrafiltration membrane filter element 5, sets super on milipore filter wash tub pipe
Filter membrane flushing valve 6；Nanofiltration core wash tub pipe is connected on the delivery port II of nanofiltration core 7, is set on nanofiltration core wash tub pipe
Nanofiltration core flushing valve 11.
The water of the outflow of delivery port I of delivery port II, nanofiltration core 7 from ultrafiltration membrane filter element 5 enters to the film surface of corresponding filter core
After row is rinsed, flushing water is formed, washed one's face and rinsed one's mouth for construction worker；The not electricity consumption in water supply process, it is not necessary to obtain coal peace certification, use
It is safe and reliable.
Nanofiltration core flushing valve 11 is three-way valve, and the first end of three-way valve is connected with nanofiltration core wash tub pipe, and it the
Two ends are connected with milipore filter flushing valve 6 by water pipe, flushing water outlet pipe are connected on its 3rd end, on flushing water water pipe
Flushing water valve 10 is set, and the flushing water of such milipore filter, the flushing water of nanofiltration core can be transported in flushing water water pipe, keep away
Exempt to need to pick out a set of water pipe, valve, material-saving respectively in ultrafiltration membrane filter element 5, nanofiltration core 7；In use, milipore filter
Opened when flushing valve 6 is different from nanofiltration core flushing valve 11.
Water intaking valve 1 is set on water inlet pipe, when workman rests or needs long-term stopping using, water intaking valve 1 is shut, is kept away
When exempting from water purifier appearance leakage, the direct current of water one.
Because the depth of mine is higher, when water is transported to shaft bottom, pressure is larger, and pressure-reducing valve is set on water inlet pipe, it is to avoid
Hydraulic pressure is excessive, damages filter core, the film silk of milipore filter and nanofiltration core is washed out so that water purifier meets underground special operation condition requirement.
Pressure gauge 3 is set on the water pipe between fore filter 2 and PP cotton filter cores 4, pressure is monitored, when pressure is excessive
When, to be overhauled, judgement is that pressure-reducing valve is damaged or filter core is stifled, is repaired in time.
The connection flow gauge 8 on nanofiltration water outlet pipe, when the pressure of the display of pressure gauge 3 is excessive, the number of degrees of flowmeter 8 are small,
Then represent that filter core has been blocked up, it is necessary to change filter core, the auxiliary repair abnormal conditions of flowmeter 8 shorten the repair time；General filter core has to be made
With limitation, it is necessary to change in time after the water of filter some amount, it is possible to according to the number of degrees of flowmeter 8, generation nanofiltration water is drawn
Amount, judge filter core whether need change.
Fore filter 2 includes shell, and sewage draining exit is provided with outer casing bottom, stainless steel filtering net is provided with shell, its mistake
Filter precision is 40 μm, and the shell of fore filter 2 is transparence, when observe it is internal cut dirty serious when, open sewage draining exit, allow water
Screen surface is rinsed.
The filtering accuracy of PP cotton filter cores 4 is 5 μm.
The filtering accuracy of ultrafiltration membrane filter element 5 is 0.01 μm, and its shell is stainless steel, durable, it is to avoid because expanding with heat and contract with cold
And rupture.
Nanofiltration core 7 is that filter core of extraordinary ultralow pressure, and nanofiltration core is by pure natural diatom fossils, nano level active charcoal and high accuracy
Ceramic membrane sintering is formed, and filtering accuracy is 0.001 μm, and when operating pressure is only 0.1Mpa, nanofiltration core can produce water, and can have
Effect removal turbidity, iron rust, suspension, bacterium, virus, microorganism, remaining fluorine, heavy metal, organic matter, retain the mineral of needed by human body
Matter；The shell of nanofiltration core is stainless steel, durable, it is to avoid to be ruptured because expanding with heat and contract with cold.
