Description

A kind of blower fan that can purify air

Technical field

This utility model relates to fluid machinery technical field, has particularly related to a kind of blower fan that can purify air.

Background technology

The use of blower fan is very extensive, and at many Factory Buildings, public place all uses blower fan air-supply to strengthen indoor air flows, but general blower fan only utilizes the rotation of impeller to produce wind-force is sent to indoor, function singleness, and noise is big, easy to leak, easy hydrops, it is impossible to cross air filtering.

Summary of the invention

The deficiency existed for prior art, the purpose of this utility model is that and provides a kind of blower fan that can purify air, simple in construction, there is noise reduction, bird rainproof, anti-, the function of blowdown, simultaneously can purification filtering air, filter area is big, resistance is little, and has radiating effect.

To achieve these goals, the technical solution adopted in the utility model is such that a kind of blower fan that can purify air, including casing, motor, described casing is fixedly connected with air inlet and air outlet；Being fixedly connected with impeller on the power transmission shaft of described motor, this impeller is fixedly installed in casing；Described air inlet includes blast pipe, blow-off pipe, filter tube, anti-bird pipe and rain cap, and described blast pipe is vertically connected at the middle part of blow-off pipe；The top of described filter tube is connected with anti-bird pipe, bottom is connected with the top of blow-off pipe, and the top of described anti-bird pipe is fixedly installed rain hat, and the bottom of described blow-off pipe is vertically installed in ground；Being provided with a drainage screen in described filter tube, described drainage screen includes that framework, filter element, described framework are rectangle, and the centre position of framework is provided with baffle plate；Described filter element is fixedly installed between framework and baffle plate.

As a kind of preferred version, the material of described filter element is impregnation filter paper.

As a kind of preferred version, described filter element includes that the size that filtering bodies and support body, described filtering bodies are the knuckle α that the folding surface on bending, and filtering bodies is formed with support body is 30 ° ~ 60 °.

As a kind of preferred version, the folding surface in described filtering bodies is 45 ° with the size of the knuckle α that support body is formed.

As a kind of preferred version, described rain cap is roof shape.

As a kind of preferred version, the perisporium of described anti-bird pipe has fresh air inlet, and is coated with bird prevention net.

Compared with prior art, the beneficial effects of the utility model: this utility model simple in construction, there is noise reduction, bird rainproof, anti-, the function of blowdown, simultaneously can purification filtering air, filter area is big, and resistance is little, and has radiating effect.

Detailed description of the invention

Below in conjunction with specific embodiment, this utility model is further described.Following example are only used for clearly illustrating the technical solution of the utility model, and can not limit protection domain of the present utility model with this.

Embodiment:

As it is shown in figure 1, a kind of blower fan that can purify air, including casing 1, motor 2, described casing 1 is fixedly connected with air inlet and air outlet 4；Being fixedly connected with impeller (owing to being installed in component, Gu Tuzhong does not shows that) on the power transmission shaft of described motor 1, this impeller is fixedly installed in casing 1；Described air inlet includes blast pipe 31, blow-off pipe 32, filter tube 33, anti-bird pipe 34 and rain cap 35, and described blast pipe 31 is vertically connected at the middle part of blow-off pipe 32；The top of described filter tube 33 is connected with anti-bird pipe 34, bottom is connected with the top of blow-off pipe 32, and the top of described anti-bird pipe 34 is fixedly installed rain hat 35, and described rain cap 35 is in roof shape；The bottom of described blow-off pipe 32 is vertically installed in ground；As shown in Figure 2 and Figure 3, being provided with a drainage screen in described filter tube 33, described drainage screen includes framework 331, filter element 332, and described framework 331 is rectangle, and the centre position of framework 331 is provided with baffle plate 333；Described filter element 332 is fixedly installed between framework 331 and baffle plate 333, and the material of described filter element 332 is impregnation filter paper, plays the effect of air filtering.

As shown in Figure 4, described filter element 332 includes filtering bodies 3321 and support body 3322, and described filtering bodies 3321 be folding surface 3323 on bending, and filtering bodies 3321 and the size of the knuckle α of support body 3322 formation is 30 ° ~ 60 °；The size of the knuckle α that the folding surface 3323 in described filtering bodies 3321 is formed with support body 3322 is 45 °.

The preferred described rain cap 35 of this utility model, in roof shape, plays waterproof rain-proof effect.

The perisporium of the preferred described anti-bird pipe 34 of this utility model has fresh air inlet, and is coated with bird prevention net, plays anti-bird insect protected and enters the effect of air inlet.

When being embodied as, motor 2 operating controls impeller and air is entered from air inlet, and rain cap 35 is for waterproof, and anti-bird pipe 34 plays anti-bird insect protected effect, then filters air via filter tube 33, is being entered by blast pipe 31, is finally being discharged by air outlet 4.

The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; on the premise of without departing from this utility model know-why; can also make some improvement and deformation, these improve and deformation also should be regarded as protection domain of the present utility model.
