Description

The defeated blower fan of removal of impurities type

Technical field

The utility model relates to mechanical engineering field, especially relates to the defeated blower fan of a kind of removal of impurities type.

Background technique

Blower fan is generally used for and improves indoor air environment, transport gas etc.And existing blower fan generally comprises housing and the motor be located in housing is fanned with rotating, but existing motor wind-force is little, transmission speed is slow, in particular for the ventilation under the rugged environment such as chemical plant, its weak effect, cannot gas in time in discharge chamber, threaten to the health of people, rotate fan rotation makes wind impact housing generation noise simultaneously, affects the mood of people, is also unfavorable for the interchange of people.In addition, the impurity such as the dust also existed in the wind in chemical plant enter outdoor and also can pollute the air of outdoor.

Model utility content

The utility model, in order to overcome the deficiencies in the prior art, provides a kind of defeated air quantity large, to the defeated blower fan of removal of impurities type of air good impurity removing effect.

To achieve these goals, the utility model is by the following technical solutions: the defeated blower fan of a kind of removal of impurities type, comprise housing, described housing forward end is wind inlet end, rear end is outlet air end, housing forms intermediate section between wind inlet end and outlet air end, motor is provided with in intermediate section, be provided with in wind inlet end and rotate fan, motor comprises the rotating shaft connecting and rotate fan, described wind inlet end have diminish gradually along wind movement direction before internal channel, outlet air end has and becomes large rear internal channel gradually along wind movement direction, and intermediate section has the straight passage being communicated with front internal channel and rear internal channel; Described wind inlet end connects a frustoconic shape air draught body, this frustoconic shape air draught body comprises the removal of impurities steel mesh be connected with wind inlet end, outer frustoconic shape is overlapped and be located at outer ring overlap in frustoconic shape cover, one end that outer frustoconic shape cover and interior frustoconic shape overlap opening less is all welded with removal of impurities steel mesh, and outer frustoconic shape cover and interior frustoconic shape form quick defeated wind passage between overlapping; Described wind inlet end inwall is provided with break-in except sound cover, and form a resettlement groove along wind movement direction bottom described inner walls, have the removal of impurities wet sponge of adsorbing contaminant in this resettlement groove, this removal of impurities wet sponge has the end face flushed with inner walls.Frustoconic shape air draught body is conducive to collecting of air quantity, and wind can be concentrated on break-in except the place's removal of impurities of sound cover by front internal channel, and move after then rotarily driving wind with fan, the rear internal channel increased gradually then can make wind naturally blow out outside housing, reduces the obstruction to wind; Inside and outside frustoconic shape cover forms Twin channel, main air body covers in housing from interior frustoconic shape, wind near interior frustoconic shape cover edge is then overlapped the passage formed between outer frustoconic shape cover and introduces in body by interior frustoconic shape, the guiding of passage to wind between interior frustoconic shape cover and outer frustoconic shape cover is effective; Wind loss is little, and the wind fast rotational in this passage can be driven to enter in housing after rotating fan rotation, increase the wind-force of blower fan, also increase defeated air quantity, also improve the defeated wind area to indoor, air improves better effects if, and removal of impurities steel mesh is set can the air of indoor discharged to outdoor be filtered for the first time, removal of impurities sponge can be adsorbed impurity such as the dusts in wind, and advantages of good adsorption effect, extent of adsorption is large, and avoid causing atmospheric pollution, the end face of removal of impurities sponge flushes with lid inwall, avoids removal of impurities sponge to have an impact to the wind in blower fan; And break-in removes the noise that sound cover can reduce the generation of wind impact inner walls; And the break-in of this structure is except sound cover also adsorbable certain impurity, further reduces the impurity content in wind.

As preferably, connecting ring before described removal of impurities steel mesh front surface periphery forms, described wind inlet end front portion is provided with a back clevis be connected with front connecting ring.This structure can facilitate the installing/dismounting of frustoconic shape air draught body, and cleaning is got up convenient, also facilitates taking-up break-in to remove sound cover simultaneously and clears up it, keep the filtering effect to air.

As preferably, described housing bottom connects a base, and this base comprises the supporting portion be connected with housing.Stably blower fan can be placed on ground bottom this.

In sum, the utility model has the following advantages: frustoconic shape air draught body is large to the amount of collecting of wind, front internal channel is conducive to the wind after by first removal of impurities and concentrates on break-in except sound and put and carry out removal of impurities, rear internal channel then can make wind naturally blow out outside housing, reduce the loss of air quantity, removal of impurities sponge and removal of impurities steel mesh can remove the impurity in wind.
