Description
Technical field
A kind of method that the present invention relates to clean air drainage screen, belongs to cleaning appliance technical field.
Background technology
Drainage screen, is typically made up of metal or synthetic fibers, for the separation of various flowing materials, the most corrosion-resistant,
Antioxidation etc..Although traditional prefiltration net such as air-conditioning net is capable of washing, but filter efficiency is extremely low, although high efficiency particulate air has very
High filter efficiency, the dust being invisible to the naked eye in removable air, but because it cannot clean service life the longest, need through
Often changing, consumer is caused troublesome poeration and increases financial burden by this.
Currently using the material of most two kind high efficiency particulate air filter, one is ultra-fine fibre glass, a kind of PP melt-blown material,
The former is because employing ultra-fine fibre glass, and the resistance using middle generation is relatively big, is typically rarely employed in domestic environment；The latter is many
Being use after compound PET aggregate, electrostatic runs off very serious after the cleaning, filter efficiency degradation.
Summary of the invention
The technical problem that present invention mainly solves: for the most compound PET aggregate and ultra-fine fibre glass, the most quiet
Electric current loses very serious, and filter efficiency degradation is relatively costly, it is provided that a kind of method of clean air drainage screen, this
Bright first being fixed by the drainage screen fixed frame of preparation is embedded in air purifier again, then under the effect of dedusting blade,
Scrape off the dust on drainage screen surface, then drainage screen one conjunction, shake dust, finally under the effect of seperator, be blown to sky
Outside gas purifier.The filter screen filtration efficiency that the present invention prepares is high, it is not necessary to dismounting cleaning, can anhydrous clean, applied widely,
Low cost, works for people, and life improves air quality and provides effective means.
In order to solve above-mentioned technical problem, the technical solution adopted in the present invention:
A kind of method of clean air drainage screen, it is characterised in that: first the drainage screen prepared is fixed by fixed frame
After Zhuing, it is embedded in air purifier, when the drainage screen in air purifier is covered with dust all over, opens air purifier
In dedusting button, be placed in drainage screen upper end and be close to the dedusting blade of drainage screen and remain stationary as, the rotating shaft of fixed frame upper end is opened
Begin to rotate so that drainage screen with the velocity of rotation of 1m/min the most upwards, scraped by dedusting blade layer by layer by the dust on drainage screen
Under, until drainage screen goes to another side, dedusting blade quits work, and is compiled into simultaneously and can start by one one drainage screen closed
Shake 10～15min, shake adheres to the dust on drainage screen, under the effect of dust centrifuge in air purifier, quilt
Being blown to outside air purifier, then drainage screen goes to front with the velocity of rotation of 1m/min again.
The concrete preparation process of described drainage screen is:
(1) 1～2m is taken2Fiber crops material, 100～the fresh grass won of 200g and the Flos Gardeniae of 50～100g, be placed in fermentation
In tank, and adding deionized water it is carried out fermentation process, wherein mixture is 1:2 with the solid-to-liquid ratio of deionized water, fermentation temperature
Degree keep 18～20 DEG C, after the sealing and fermenting time is 15～20 days, improve fermentation temperature to 30～35 DEG C, fermentation time be 20～
25 days, control fermentation condition for ventilation, lucifuge；
(2) taking out the turbid liquid of the mixing in above-mentioned fermentation tank, filter it, the fiber crops material after being fermented, simultaneously with clear
After fiber crops material is rinsed well by water, being placed in vacuum machine, be passed through superheated steam, temperature is set as 200～300 DEG C, and Stress control is
0.1MPa, the time is 30～40min, carries out steaming and decocting；
(3), after being cooled to room temperature, the sodium carbonate of the 1% of addition fiber crops material quality and fiber crops expect 0.05% hydroxide of quality
Sodium, heats, and temperature is 90～100 DEG C, and the time is 30～40min, then takes out, and carries out machinery filature, through rereeling and whole
Reason, processes filamentation；
(4) area that above-mentioned prepared silk is woven into each little lattice is 0.1～5cm2, entire area be 25～
10000cm2, thickness is 0.3～5cm drainage screen,.
The application of the present invention: after first the drainage screen prepared being fixed by fixed frame, be embedded into into air cleaning
In device, when the drainage screen in air purifier is covered with dust all over, opens the dedusting button in air purifier, be placed in drainage screen
Upper end is also close to the dedusting blade of drainage screen and is remained stationary as, and the rotating shaft of fixed frame upper end starts to rotate so that drainage screen is with 1m/
The most upwards, the dust on drainage screen is scraped the velocity of rotation of min by dedusting blade layer by layer, until drainage screen goes to another
Face, dedusting blade quits work, and is compiled into simultaneously and can start to shake 10～15min by one one drainage screen closed, and shake is viscous
Invest the dust on drainage screen, under the effect of dust centrifuge in air purifier, outside being blown to air purifier, connect
Drainage screen and go to front with the velocity of rotation of 1m/min again.
The invention has the beneficial effects as follows:
(1) filter screen filtration efficiency is high, it is not necessary to dismounting cleaning, can anhydrous clean；
(2) preparation technology is simple, applied widely, low cost.
