Description
Technical field
The utility model relates to a kind of water-treatment technology field, especially relates to a kind of milipore filter water purification unit.
Background technology
Milipore filter is that a kind of aperture specification is consistent, and specified pore diameter range is the micropore filtering film of 0.001-0.02 micron.A side at film imposes suitable pressure, just can sift out the solute molecule less than the aperture, the isolated molecule amount is greater than 500 dalton, the particle diameter particle greater than 2～20 nanometers, and milipore filter is one of polymeric membrane for separation of developing the earliest, the sixties ultrafiltration apparatus just realized industrialization.
Traditional milipore filter water purification unit as shown in Figure 1, the filter core cylinder that comprises milipore filter and be positioned at described milipore filter outside, wherein be provided with former aquaporin on filter core cylinder, milipore filter has pure water passage and waste water tunnel, the former water that pressurizes enters in milipore filter from the import of former aquaporin, flow out in the pure water passage through the pure water after the filtration of milipore filter, the particle diameter in water has been stayed in waste water tunnel greater than the impurity such as particle of 2～20 nanometers, realizes thus the water purification process.Will residual too much impurity in its inner hole wall after milipore filter water purification unit service time is long, thus cause that water yield is few, water quality is low, the problems such as reductions in service life of water purification unit, therefore need regularly the water purification unit is cleaned.
A large amount of cleaning solutions that traditional cleaning method will contain cleaning agent are passed in former aquaporin, cleaning fluid is through milipore filter, the impurity that it is inner is taken away by the souring of flowing water, and flow out by dense aquaporin, this method needs larger hydraulic pressure, the impurity that penetrates into film inside can be washed away away, because the arrangement between every layer of milipore filter is tight, therefore when it is cleaned, need to consume a large amount of clean solutions.
Summary of the invention
The purpose of this utility model is to provide a kind of water saving and the convenient milipore filter water purification unit that cleans.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of milipore filter water purification unit, described water purification unit comprises filter core, described filter core includes the milipore filter that is positioned at described filter core center and the filter core cylinder that is positioned at described milipore filter outside, offer a former water inlet on the lateral wall of described filter core, one end of described filter core is provided with dense water out, the other end is provided with pure water outlet, and described water purification unit also comprises at least one supersonic generator that is positioned at described filter core outside, and described filter core cylinder is metal material.
In preferred version, described filter core outer setting has a plurality of supersonic generators, and described a plurality of supersonic generators are along circumferentially evenly being arranged on the barrel of described filter core cylinder.
In preferred version, described filter core outer setting has a plurality of supersonic generators, and described a plurality of supersonic generators evenly are arranged on the barrel of described filter core cylinder vertically.
In preferred version, described filter core cylinder is stainless steel.
The utility model operation principle is:
A kind of milipore filter water purification unit, comprise at least one supersonic generator that is positioned at the filter core outside, when cleaning milipore filter, close dense water out, open supersonic generator, supersonic generator with power ultrasonic frequently the acoustic energy in source convert the ultrasonic vibration of machinery to, when the sound wave pressure of propagating in liquid when ultrasonic vibration reached an atmospheric pressure, its power density was 0.35w/cm
2, at this moment hyperacoustic sound wave pressure spikes just can reach vacuum or negative pressure, but in fact exists without negative pressure, therefore produces a very large power in liquid, and the fluid molecule drawing crack is become cavity---cavitation nucleus.This cavity is very near vacuum, and it breaks when ultrasonic wave pressure oppositely reaches maximum, and the intense impact that produces owing to breaking clashes into the impurity in the ultrafiltration fenestra get off.Then supersonic generator stops vibration, opens dense water out, thereby dense water is taken away the dirt that cleans, and can reach the purpose to the unit cleaning of milipore filter water purification.
Because technique scheme is used, the utility model compared with prior art has following advantages:
In milipore filter water purification catridge outside, at least one supersonic generator is installed, when milipore filter water purification unit is cleaned, effect due to ultrasonic vibration, can be with under the dirt shock that infiltrates in the ultrafiltration fenestra, and taken away by dense water, it is compared with conventional art, and it does not need to configure in addition cleaning solution, has also reduced the water consumption of cleaning simultaneously.

The specific embodiment
Below in conjunction with the drawings and the specific embodiments, the utility model is further described:
accompanying drawing 1 is depicted as the structural representation of the milipore filter water purification unit of prior art, this water purification unit comprises filter core 1, wherein filter core 1 comprises the milipore filter 2 that is positioned at filter core 1 center and the filter core cylinder 3 that is positioned at milipore filter 2 outsides, offer a former water inlet 4 on the lateral wall of filter core 1, one end of filter core 1 is provided with dense water out 5, the other end is provided with pure water outlet 5, accompanying drawing 2-4 is the structural representation to the milipore filter water purification improved embodiment 1 in unit of prior art, it adds a supersonic generator 7 on filter core 1 outer wall of the milipore filter water purification unit of prior art, this supersonic generator 7 can be pasted or weld or directly be fixed on filter core 1 outer wall, in order to guarantee the service efficiency of this supersonic generator 7, filter core cylinder 3 adopts the metal stainless steel to make.
When cleaning milipore filter 2, close dense water out 5, and open simultaneously supersonic generator 7, carry out the Ultrasonic Cleaning of milipore filter 2, Ultrasonic Cleaning be utilize cavitation, direct flow effect and the acceleration effect of ultrasonic wave in liquid to liquid and dirt directly, indirectly effect, make that crud layer is dispersed, emulsification, peel off and break away from the milipore filter surface.
