Description
Technical Field
The utility model relates to an air purification field especially indicates a FFU fan filter unit.
Background
The Fan Filter Unit (FFU) is a modular terminal air supply device with power and a filtering effect, the general installation mode is indoor ceiling installation, the FFU is connected in series or in parallel, the fan filter unit is suitable for large-scale air purification places such as various clean rooms and dust-free workshops and the like which need a large amount of air flow to remove pollution particles, the fan sucks air from the top of the FFU, the air is filtered by an air filter, and the filtered clean air is sent into the room. Because the FFU has the advantages of low energy consumption, low noise, small vibration, large air volume and the like, the FFU is widely applied to various clean rooms and dust-free workshops. However, in the prior art, when clean air enters a room through the FFU, the flow of the air is relatively disordered and the wind speed is not uniform.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a wind speed is even, can ensure that the air homoenergetic of all indoor positions obtains the FFU fan filter unit who purifies.
In order to solve the technical problem, the utility model provides a technical scheme as follows:
the utility model provides a FFU fan filter unit, includes the casing and sets up the fan in the casing, the air intake top that lies in the fan on the casing has set gradually wind-guiding circle and primary filter, the air outlet below that lies in the fan in the casing has set gradually aviation baffle and high efficiency filter.
Furthermore, the bottom of casing is provided with the bottom plate, high efficiency filter is located on the bottom plate, high efficiency filter's up end be provided with a plurality of with bottom plate bolted connection's layering.
Further, the air deflector comprises a fixing plate for fixing the fan and folded plates arranged at two ends of the fixing plate, and the angle between the folded plates and the fixing plate is 15-60 degrees.
Furthermore, the upper end of casing is provided with the fixing base, two at least sides of fixing base are provided with the cardboard of inside bending, primary filter joint is in the cardboard.
Compared with the prior art, the utility model discloses following beneficial effect has:
the utility model discloses a FFU fan filter unit sets up wind-guiding circle and aviation baffle respectively in the air intake and the air outlet department of fan, and outside air can only get into indoorly through fan, high efficiency filter under the effect of wind-guiding circle and aviation baffle behind the primary filter to under the guide effect of wind-guiding circle and aviation baffle, it is more even to flow in indoor wind speed, makes the air homoenergetic of indoor all positions obtain purifying, ensures the indoor air cleanliness factor.

Detailed Description
In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.
The utility model provides a FFU fan filter unit, as shown in fig. 1-3, including casing 4 with set up fan 6 in casing 4, the air intake top that lies in fan 6 on casing 4 has set gradually wind-guiding circle 5 and primary filter 1, and the air outlet below that lies in fan 6 in casing 4 has set gradually aviation baffle 7 and high efficiency filter 9.
The utility model provides a 6 filter unit of FFU fan sets up wind-guiding circle 5 and aviation baffle 7 respectively in the air intake and the air outlet department of fan 6, outside air can only pass through fan 6 under the effect of wind-guiding circle 5 and aviation baffle 7 after primary filter 1, high efficiency filter 9 gets into indoorly, and under the guide effect of wind-guiding circle 5 and aviation baffle 7, it is more even to flow into indoor wind speed, make the air homoenergetic of indoor all positions obtain purifying, ensure the room air cleanliness factor.
Because high efficiency filter sets up inside casing 4, most adopt among the prior art to glue the processing to high efficiency filter's fixed mode, when needs maintenance or change high efficiency filter, high efficiency filter is difficult to demolish in the casing. To solve this problem, in an embodiment of the present invention, a bottom plate 4-1 is disposed at the bottom end of the housing 4, the high efficiency filter 9 is disposed on the bottom plate 4-1, and a plurality of pressing bars 8 are disposed on the upper end surface of the high efficiency filter 9 and bolted to the bottom plate 4-1. The utility model discloses an use layering 8 to sticis high efficiency filter 9 on bottom plate 4-1 of casing 4, adopt bolted connection between the tip of layering 8 and the bottom plate 4-1, when needing to demolish high efficiency filter 9 because of the maintenance or with changing, only need loosen the bolt, with high efficiency filter 9 from between layering 8 and the bottom plate 4-1 take out can.
In order to further improve the guiding effect of the air deflector 7 on the clean air, so that the clean air flows uniformly into the room, and the air at each corner in the room can be purified, in an embodiment of the present invention, the air deflector 7 includes a fixing plate 7-1 for fixing the fan 6 and folding plates 7-2 disposed at both ends of the fixing plate 7-1, an angle between the folding plate 7-2 and the fixing plate 7-1 is 15 ° -60 °, and fig. 3 is a schematic view showing the air flow direction under the action of the air deflector 7.
In one embodiment of the present invention, the upper end of the housing 4 is preferably provided with a fixing base 2, at least two sides of the fixing base 2 are provided with clamping plates 2-1 bent inward, and the primary filter 1 is clamped in the clamping plates 2-1. The primary filter 1 is clamped in the fixed seat 2 through the clamping plate 2-1, so that the installation and the replacement are convenient.
The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
