Description
Technical field
This utility model relates to a kind of filter screen, specifically a kind of air cleaning filter screen.
Background technology
Along with the development of science and technology, people increasingly pay attention to IAQ (indoor air quality) so that air filting material takes on the role become more and more important in environmental improvement；nullSimultaneously，No matter air filting material in quantity or is proposed new requirement by the development of udst separation technology and raising in kind and quality，Prior art generally adds last layer deodorizing layer so that it possesses deodorizing effect on air filter screen，This deodorizing layer is whole piece，Material is generally activated carbon，It is active carbon layer，This type of air filter screen is when beginning to use，Effect is pretty good，But it is of a specified duration along with using，Its deodorizing effect just weakens significantly，Because in the life-time service of air filter screen，Active carbon layer is easily by wind-force compacting，Table aperture in activated carbon is destroyed and affects adsorption effect，Therefore a kind of air filter screen it is badly in need of，The deodorizing effect persistent period is long，Simple in construction，With low cost，Fan it is provided with in air cleaning facility，Air cleaning facility is connected with drainage screen，After air cleaning facility works a period of time，Staff can find that the air quantity of fan is little especially，But now，Fan is still in normal operation，By each building block of air cleaning facility is investigated，The air quantity of discovery fan is little is caused by the filter screen dust stratification being located at below air cleaning facility is blocked up，Therefore，Need in time the dust of filter screen to be processed，In prior art，And it is absent from the excessive alarm device of air cleaning facility dust on filter screen，Only by maintainer actively go investigation dust on filter screen whether blocked up.
Utility model content
The purpose of this utility model is in that to provide a kind of air cleaning filter screen, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme:
A kind of air cleaning filter screen, including by the first module, the second module, three module and dust alarm device, described first module is wire gauze；Second module includes the first nonwoven layer and the second nonwoven layer, in first nonwoven layer, distribution has grid-like air runner, air flow channel is circular design, first nonwoven layer is provided with the spongy layer of a covering air flow channel, air flow channel extends air flow channel branch to spongy layer, and air flow channel branch highlights spongy layer surface；Described three module is mesh container, is provided with the face of giving vent to anger and air inlet face, and this air inlet face and the face of giving vent to anger are network structure；Described three module center, face of giving vent to anger is provided with dust alarm device, dust alarm device includes box of collecting folk songs, and collects folk songs box-packed in the inlet end of wind pressure transmitter, and wind pressure transmitter electrically connects with data acquisition unit, data acquisition unit is electrically connected with decision circuit by transducer, and decision circuit electrically connects with alarm.
Further, the diameter of described air flow channel is 1.5mm.
Further, being filled with activated carbon in described air flow channel, activated carbon adopts coconut husk charcoal.
Further, the thickness of described spongy layer is 2mm.
Compared with prior art, it is filled with activated carbon in air flow channel of the present utility model, not only active adsorption abnormal flavour, also accelerates air filter screen and the flowing of outside air simultaneously, improve the adsorption filtration effect of activated carbon；Adopt latticed design, it is possible to effectively coherent whole air flow channel, it is to avoid cause air flow blockage；Adopting flow channel type design, what decrease activated carbon makes consumption, reduces production cost simultaneously, and activated carbon adopts coconut husk charcoal, utilizes the strong adsorptivity of coconut husk charcoal, strengthens the filter effect of air filter screen, is beneficial to absorption abnormal flavour, strengthens air filtration effect；This utility model passes through wind pressure transmitter perception filter screen laying dust situation, and wind pressure transmitter perception is sensitive, and perception data can transmit and monitor in real time, real-time, reliability are high, use this utility model, advantageously reduce O&M cost and pressure, save human cost, improve work efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of air cleaning filter screen.
Fig. 2 is the structural representation of dust alarm device in air cleaning filter screen.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the technical scheme of this patent is described in more detail.
Referring to Fig. 1-2, a kind of air cleaning filter screen, including by first module the 1, second module 2, three module 3 and dust alarm device 4, described first module 1 is used for prefiltration prime bulky grain foreign material for wire gauze；Second module 2 includes the first nonwoven layer 21 and the second nonwoven layer 22, in first nonwoven layer 21, distribution has grid-like air runner 23, air flow channel 23 is circular design, the diameter of air flow channel 23 is 1.5mm, it is filled with activated carbon in air flow channel 23, activated carbon adopts coconut husk charcoal, first nonwoven layer 21 is provided with the spongy layer 24 of a covering air flow channel 23, the thickness of spongy layer 24 is 2mm, air flow channel 23 extends air flow channel branch 25 to spongy layer 24, air flow channel branch 25 highlights spongy layer 24 surface, it is filled with activated carbon in air flow channel 23, not only active adsorption abnormal flavour, also accelerate air filter screen and the flowing of outside air simultaneously, improve the adsorption filtration effect of activated carbon；Adopt latticed design, it is possible to effectively coherent whole air flow channel, it is to avoid cause air flow blockage；Adopting flow channel type design, what decrease activated carbon makes consumption, reduces production cost simultaneously, and activated carbon adopts coconut husk charcoal, utilizes the strong adsorptivity of coconut husk charcoal, strengthens the filter effect of air filter screen, is beneficial to absorption abnormal flavour, strengthens air filtration effect；Described three module 3 is mesh container, be provided with the face of giving vent to anger and air inlet face, and in order to ventilate, this air inlet face and the described face of giving vent to anger be network structure, and three module 3, except further dedusting, is filled with the both effectiveness component substances of expection betwixt in gap；nullDescribed three module 3 center, face of giving vent to anger is provided with dust alarm device 4，Dust alarm device 4 includes box 41 of collecting folk songs，Box 41 of collecting folk songs is loaded on the inlet end of wind pressure transmitter 42，Wind pressure transmitter 42 electrically connects with data acquisition unit 43，Data acquisition unit 43 is electrically connected with decision circuit 45 by transducer 44，Decision circuit 45 electrically connects with alarm 46，By box 41 of collecting folk songs at three module 3 place collection air force，Then under the effect of wind pressure transmitter 42，The magnitude of voltage of corresponding size is converted to according to the air force collected，The magnitude of voltage that wind pressure transmitter 42 is sent here by data acquisition unit 43 sends decision circuit 45 to by transducer 44，The magnitude of voltage received and the pre-determined threshold magnitude of voltage being stored in decision circuit 45 in advance are compared by decision circuit 45，If the magnitude of voltage that decision circuit 45 receives is lower than pre-determined threshold magnitude of voltage，Then send an alarm signal to alarm 46，Alerted by alarm 46，Prompting user's filter screen laying dust is serious，Need to carry out dust removal operation.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, it is also possible to make a variety of changes under the premise without departing from this patent objective.
