Background technique
The professional term of FFU Chinese is a blower fan filtering unit, exactly blower fan and filter set is lumped together the terminal cleaning equipment that formation self can provide power.Its working principle is: blower fan is sucked air by the FFU top and filters through roughing efficiency air filter, and the clean air after the filtration is seen off via exhaust outlet, and blower fan filtering unit has replaced distributed air-conditioning unit and blower fan cooling system fast.FFU is as the terminal cleaning equipment of cleanroom, and what on China market, occur has only more than ten years, the design of its modular structure, easy construction; Add easily in the existing cleanroom; Need not a large amount of renovations, when the user needs part upgrading cleanliness, need not improve the roof and perhaps demolish walls; Only need to set up the FFU unit on the top and get final product, need clean area to deal with all around and get final product.Therefore present domestic employing is more and more; Development speed is very fast, but in the FFU performance, noise is one of its important techniques index; And the design in air channel and noise exist very big relation, and a lot of manufacturers are because the air channel design is rationally little and then cause FFU unit noise very big.If when improving the clean efficient of filter, can avoid noise again, with the performance that improves filter to a great extent.
Fan filter unit F FU is widely used in the cleanroom, clean bench, clean operational sites such as clean production line and assembly type cleanroom.
The model utility content
The purpose of the utility model is the shortcoming that overcomes existing technology; A kind of blower fan filtering unit FFU is provided the air channel; It is simple in structure, low cost of manufacture, long service life; When improving the clean efficient of filter, can improve the performance of the utility model to a great extent through the cotton noise that reduces of noise reduction again.
For reaching above-mentioned purpose, a kind of blower fan filtering unit FFU air channel that the utility model provides, the technological scheme below adopting: the utility model comprises casing; The end face middle part of said casing is provided with circular trough; Be provided with the blower fan body in the said circular trough, the top face of said casing is provided with control system, and said control system is arranged near the blower fan body; It is cotton that said interior is provided with first noise reduction, and the said first noise reduction cotton is arranged at the top and the left and right sides portion of casing; The bottom position of said casing is provided with guide plate; Said guide plate is parallel to the end face of casing; It is cotton that the internal surface of said guide plate is provided with second noise reduction, and the left surface of said guide plate and casing forms first exhaust outlet, and the right flank of said guide plate and casing forms second exhaust outlet.
Further, the cotton thickness of said first noise reduction is 25mm, and the cotton thickness of said second noise reduction is 50mm.
Further, said bottom half is no baffle filter, and each side of said casing is equipped with protection apron with the neutral position of no baffle filter.
Further, the length that is shorter in length than said casing of said guide plate, said guide plate is fixed in the central position of said casing inner bottom part through blind rivet.
The beneficial effect of the utility model is: the utility model is simple in structure; The convenient transformation or manufacturing; Long service life; Demand through calculating noise reduction static pressure space and cost construct the noise reduction air channel an of the best with the noise reduction cotton between said guide plate and casing, the noise reduction cotton has effectively reduced noise and the noise of this of blower fan generation between wind and the sheet material, and the FFU noise can be controlled to 45dB.
The utility model is installed very convenient, effectively raises working efficiency, has saved fabricating cost, need not welding, baking vanish etc., only needs with blind rivet assembly to be coupled together, and is convenient to promotion and implementation.
Description of drawings
Shown in Figure 1 is the utility model structure sectional view.
Shown in Figure 2 is the utility model overall structure schematic representation.
Below be the explanation of the utility model component sign flag:
Casing 1, blower fan body 2, control system 3, first noise reduction are cotton 4, cotton 6, first exhaust outlet 7 of guide plate 5, second noise reduction, second exhaust outlet 8, no baffle filter 9, protection apron 10.
Embodiment
For further understanding characteristic, technological means and the specific purposes that reached, the function of the utility model; Resolve the advantage and spirit of the utility model, by the detailed description of the utility model further being understood below in conjunction with accompanying drawing and embodiment.
Shown in Figure of description; The described a kind of blower fan filtering unit FFU of the utility model air channel comprises casing 1, and the end face middle part of said casing 1 is provided with circular trough; Be provided with blower fan body 2 in the said circular trough; The top face of said casing 1 is provided with control system 3, and said control system 3 is arranged near the blower fan body 2, and said control system 3 mainly is used for controlling the running in this FFU air channel; The word of expression locality is according to the location definition in this Figure of description in the utility model, and is all effective for the location expression after any change accompanying drawing direction.
Said casing 1 internal surface is provided with first noise reduction cotton 4, and the thickness of said first noise reduction cotton 4 is 25mm.Said first noise reduction cotton 4 is arranged at the top and the left and right sides portion of casing 1; First noise reduction cotton 4 that is arranged at casing 1 top has the special shape that is complementary with casing 1 shape respectively with first noise reduction that is arranged at casing 1 left and right sides portion cotton 4, and this design not only makes the utility model attractive in appearance but also more practical.
