Description
Technical field
The utility model relates to mechanical engineering field, especially relates to a kind of environment protection type blower fan.
Background technique
Existing blower fan is for the ease of maintenance, and housing can be divided into upper shell and lower shell body, and when blower fan is used for transmitting the gas that has pollution, gas easily spills and befouling environment the finedraw between upper shell and lower shell body; And enclosure interior can arrange the support body of mounted motor, this arranges installing/dismounting motor difficulty, inconvenient during cleaning housing, and not thorough, support body volume is large simultaneously, affects the air-out of blower fan, also can increase the weight of blower fan, mobile inconvenient, and when blower fan breaks down, be difficult to thoroughly check; And only at intake grill place, one filter screen is set, filtered air weak effect; When blower fan is worked, the wind spilling from wind wheel end can impact housing and produce noise simultaneously; The wind direction of the wind of discharging is mixed and disorderly, easily cuts down wind-force, and part wind can impact housing and produce noise, reduces air output.
Model utility content
The utility model, in order to overcome the deficiencies in the prior art, provides a kind of good sealing effect, the environment protection type blower fan that working efficiency is high.
To achieve these goals, the utility model is by the following technical solutions: a kind of environment protection type blower fan, comprise casing, in described casing, be provided with motor and wind wheel, the left end of described housing is air intake, and the right-hand member of housing is outlet air end, described motor comprises the rotating shaft that connects wind wheel, described housing side is sealing configuration, also comprises fit frame, and described fit frame comprises the first filter screen and the second filter screen that is individually fixed in housing air intake and outlet air end; The first filter screen and wind wheel corresponding part are provided with wind-collection cover, between this first filter screen and the second filter screen, by three coupling shafts, connect; These three coupling shafts and wind wheel corresponding part are arranged with barney; In the middle of these three coupling shafts, be provided with the dispenser for fixed electrical machinery; Described dispenser is to be sheathed on fixedly group of the installation sleeve of outside motor and at least one group, this fixedly group be three fixing rods, these three fixing rod one end connection covers, these three fixing rod the other ends connect three coupling shafts successively, and the centre of fixing rod is provided with induced-draft plate along axis.
As preferably, described fixedly group is 2 groups, and the edges at two ends outside of described housing is provided with chimb, and described the first filter screen is connected with chimb by screw with the second filter screen.
In sum, the utlity model has following advantage: on housing,, without finedraw, transmission does not pollute the environment while having dusty gas; This zoarium frame is set the parts of enclosure interior are all arranged on fit frame, and fit frame is lightweight, be convenient to move, installing/dismounting is more convenient; When parts damages, can check more all sidedly, and dispenser is less than the support body volume of traditional fixed electrical machinery, has further increased air output, has improved the efficiency of blower fan, can also clear up more thoroughly Blower Housing; The two ends of fit frame arrange to filter has strengthened filtering effect, and the first filter screen and the second filter screen have reduced impurity, avoid damaging motor, further reduced impurity, when fan action is ventilation, made inner air cleaner, when blower fan is exhaust, reduced environmental pollution; On fit frame, barney is set, the wind that has reduced to spill from wind wheel end impacts housing and produces noise; Induced-draft plate is set, changes the air-flow of wind outlet, and then changed the wind direction of air-out, it is discharged towards Way out, improved the efficiency of air-out.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to make those skilled in the art person better understand the utility model scheme, below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is carried out to clear, complete description.
As shown in Figure 1, a kind of environment protection type blower fan, the casing 1 that comprises side seal, in described casing 1, be provided with motor 3 and wind wheel 2, the left end of described housing 1 is air intake 11, and the right-hand member of housing 1 is outlet air end 12, and described motor 3 comprises the rotating shaft that connects wind wheel 2, also comprise fit frame 4, described fit frame 4 comprises the first filter screen 41 and the second filter screen 42 that is individually fixed in housing 1 air intake 11 and outlet air end 12; The first filter screen 41 is provided with wind-collection cover 411 with wind wheel 2 corresponding parts, between this first filter screen 41 and the second filter screen 42, by three coupling shafts 43, connects; These three coupling shafts 43 are arranged with barney with wind wheel 2 corresponding parts; In the middle of these three coupling shafts 43, be provided with the dispenser 431 for fixed electrical machinery 3; Described dispenser 431 is for being sheathed on fixedly group of the installation sleeve of motor 3 outsides and at least one group, this fixedly group be three fixing rods, these three fixing rod one end connection covers, these three fixing rod the other ends connect three coupling shafts 43 successively, and the centre of fixing rod is provided with induced-draft plate along axis.
