Embodiment
The moveable rear-mounted balanced ventilation device of blower fan in blowing and drawing ventilation system of the present invention.
The present apparatus is by device housings (1), frequency conversion fan (2), protection network (3), homogenizing plate (4), cowling panel (5), screen pack
(6) six parts are constituted, and frequency conversion fan (2), protection network (3), homogenizing plate (4), cowling panel (5), screen pack (6) etc., which are each attached to, to be set
On standby shell, device housings are fixed on rack, have below the rack available for mobile pulley gear screen pack (6),
Frequency conversion fan (2), cowling panel (5), homogenizing plate (4), protection network (3) are sequentially arranged by air flow, and set one each other
Determining deviation.
Screen pack (6) is made up of metal abortive haul and filter cotton with supporting role, be designed as can convenient dismounting structure
Mode, the suction for preventing foreign matter and big dust particle.Cowling panel (5) is less than between 2mm more than two layers porous plate by thickness
Build at a certain distance, for the air-flow of frequency conversion fan to be carried out into rectification, lift airflow homogeneity.In a preferred embodiment
In, the cowling panel (5) is sandwich construction, and mutually each layer cowling panel plate hole it is interlaced set, and first layer and most
The plate hole alignment of later layer cowling panel.Particularly, filter cotton is additionally provided among the plate hole of the cowling panel, the filter cotton is for example
On the inwall that the plate hole can be sticked to, so when air-flow passes through every layer of cowling panel, because the hole between each laminate is to hand over
Wrong, such air-flow can change direction between each laminate, ceaselessly hit the plate hole per laminate, so further functioned as mistake
The effect of air filtering.Meanwhile, this be staggered can eliminate the vector of air-flow in a rotational direction so that air-flow air-out is more
Uniformly, last velocity attitude is more unified.
Homogenizing plate (4) thickness is less than 30mm cellular porous plate, the uniformity for further lifting air-flow, it is ensured that send
The uniformity of wind apparatus air-supply.
Protection network (3) is stainless steel abortive haul, mainly for the protection of homogenizing plate (4).
In a preferred embodiment, blowing and drawing ventilation system of the present invention also includes water circulation system, for empty to pressure-vaccum
Gas is washed and filtered.The water circulation system includes being arranged on the hydrops groove of the lower section of rack 7 of the blower fan, and micro electric
Water in hydrops groove is drawn into the curtain that the drips (figure being arranged between homogenizing plate (4) and cowling panel (5) by machine, the micromachine
Not shown in) top.The curtain that drips can be such as sponge with water absorbing capacity, and its top is provided with dropping bath, uses
The recirculated water of coming is conveyed in receiving micromachine.Dropping bath is evenly distributed in the top of the water suction curtain, by water droplet to water suction
On curtain.The power of regulation motor can control the speed of dropping water of dropping bath.For example when needing blow at a high speed, it can increase
The speed dripped.It is that can further remove the molecule in air using the benefit for the curtain that drips.So air just has three
Layer filtering.I.e. first layer be screen pack (6) filtering, the second layer be cowling panel (5) filter, third layer position drip curtain filter.Meanwhile,
This can also play a part of decreasing temperature and increasing humidity in summer, and the benefit to human body is obvious.Most of recirculated water can be with
The curtain that drips falls back in the hydrops groove in rack 7, then circulated next time by motor under gravity.Particularly, it is described
Hydrops groove also has moisturizing and changes the function of water.The hydrops groove can take out from rack, remove wherein seriously polluted
Water, change clear water after, in rack is inserted into.
When using water circulation system, water leg need to be above set from top to down in corresponding homogenizing plate (4).By the curtain that drips
Air afterwards can carry a certain amount of steam, be not intended to see if steam is excessively for we, therefore in the plate hole of homogenizing plate
Surface engraves water leg, and so unnecessary steam can be just flowed to along water leg in the hydrops groove of lower section rack.
When the rear-mounted balanced ventilation device of blowing and drawing ventilation system blower of the present invention works, frequency conversion fan (2) provides wind
Mobilization force, air enters from screen pack (6), prevents the entrance of foreign matter and big dust particle；The rectified plate of air (5) and homogenizing plate
(4) fully blown out after rectification through protection network (3), realize the purpose for sending out uniform wind.
Although be described in detail to the present invention in conjunction with the embodiments, it should be understood by those skilled in the art that
Ground is that the various amendments, deformation under without departing substantially from spirit of the invention and essence are all allowed, and they both fall within right of the present invention
It is required that protection domain among.
