Description
Technical field
The utility model relates to ventilating machinary apparatus field, especially relates to a kind of blower fan.
Background technique
Blower fan is widely used in the industries such as electric power, iron and steel, cement, because of in the gas medium of conveying containing a large amount of hard dust, these hard dust so the gas exported from the exhaust outlet of blower fan also can adulterate.But in dust-free workshop, need higher cleanliness, in order to avoid affect the normal production of Devices in Workshop by the air after blower ventilating.
As can be seen here, how to design a kind of blower fan, can reducing blower fan delivery air, to possess higher cleanliness be current those skilled in the art's problem demanding prompt solution.
Model utility content
In order to solve the problem, the utility model provides a kind of blower fan that can improve delivery air cleanliness.
A kind of blower fan of the utility model, described casing comprises exhaust outlet and intake grill, described exhaust outlet place is provided with the purification plate for preventing large-scale particle from blowing out from described casing internal, described purification plate and described casing are for removably connecting, regulator plate and the controlling device for regulating air output is provided with in described intake grill, described controlling device comprises is located at connecting rod outside described casing and transmission circle, described connecting rod and described transmission circle are connected and fixed by the cylinder on described transmission circle, and described regulator plate is fixed on described air inlet by described cylinder.
Further, described purification plate is Air Filter, and described Air Filter is fixedly connected with described casing by grafting.
Further, described exhaust outlet is opened in the front-end face of described casing, and described intake grill is located at the side of described casing.
Further, described transmission circle is fixedly connected on outside described casing by fixed block, and described fixed block is fixedly connected with described casing by welding.
Further, described casing lower end is fixed with base.
A kind of blower fan of the utility model, compared with prior art has the following advantages:
The first, in this blower fan, exhaust outlet place is provided with the purification plate for preventing large-scale particle from blowing out from described casing internal, and purification plate and casing are removably connect so that the replacing of described purification plate.This design significantly can reduce delivery air in described exhaust outlet and, containing the quantity of hard dust, improve the cleanliness of delivery air.Being provided with regulator plate and the controlling device for regulating air output in intake grill, the size of air output can be regulated by controlling device according to the actual requirements.Controlling device comprises is located at connecting rod outside casing and transmission circle, and connecting rod and transmission circle are connected and fixed by the cylinder on transmission circle, and regulator plate is fixed on air inlet by cylinder.This controlling device structure is simple, be convenient to the size regulating air output, namely rotated by outer installment power plant drivening rod and transmission circle, thus make cylinder drive regulator plate to rotate, the angular dimension rotated according to regulator plate so just can regulate the size of air output.
The second, the purification plate in this blower fan is Air Filter, and Air Filter is fixedly connected with casing by grafting.Air Filter effectively can stop that hard dust blows out from described casing internal, effectively improves the cleanliness of exhaust outlet delivery air on the one hand; The cost of Air Filter is lower on the other hand, is beneficial to the cost of production reducing blower fan.Grafting why is adopted also to be installation and removal for the ease of Air Filter and casing.
3rd, in this blower fan, exhaust outlet is opened in the front-end face of casing, and intake grill is located at the side of described casing.This design is beneficial to air draught and enters described intake grill, and can be fast as far as possible air be exported from described exhaust outlet, thus improve the working efficiency of described blower fan.

Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As Figure 1-3, a kind of blower fan, comprises casing, and described casing comprises exhaust outlet and intake grill 4, and described exhaust outlet place is provided with the purification plate 3 for preventing large-scale particle from blowing out from described casing internal.Described purification plate 3 and described casing are for removably connecting.Why described purification plate 3 is set to described casing and removably connects mainly for the ease of the replacing of described purification plate 3.This design significantly can reduce delivery air in described exhaust outlet and, containing the quantity of hard dust, improve the cleanliness of delivery air.
In the present embodiment, described purification plate 3 is Air Filter, and described Air Filter is fixedly connected with described casing by grafting.Air Filter effectively can stop that hard dust blows out from described casing internal on the one hand, effectively improves the cleanliness of described exhaust outlet delivery air; The cost of described Air Filter is lower on the other hand, is beneficial to the cost of production reducing this blower fan.Grafting why is adopted also to be installation and removal for the ease of described Air Filter and described casing.
Being provided with regulator plate 6 and the controlling device for regulating air output in described intake grill 4, the size of air output can be regulated by described controlling device according to the actual requirements.Described controlling device comprises is located at connecting rod 1 outside described casing and transmission circle 2, and described connecting rod 1 is connected and fixed by the cylinder on described transmission circle 2 with described transmission circle 2, and described regulator plate 6 is fixed on described intake grill 4 place by described cylinder.This controlling device structure is simple, be convenient to the size regulating described air output, namely described connecting rod 1 and described transmission circle 2 is driven to rotate by outer installment power plant, thus making described cylinder drive described regulator plate 6 to rotate, the angular dimension rotated according to described regulator plate 6 so just can regulate the size of described air output.
Described exhaust outlet is opened in the front-end face of described casing, and described intake grill 4 is located at the side of described casing.This design is beneficial to air draught and enters described intake grill 4, and can be fast as far as possible air be exported from described exhaust outlet, thus improve the working efficiency of described blower fan.
In order to make described transmission circle 2 more steady when rotating, so described transmission circle 2 is fixedly connected on outside described casing by fixed block, described transmission circle 2 is made to have certain rotation track.In order to make the connection of described fixed block and described casing more firm, so described fixed block is fixedly connected with described casing by welding.
In order to make this blower fan more steady when normally working, so be fixed with base 5 in described casing lower end.This design makes described blower fan more firm in operation process, not easily topples over.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
