Abstract
The utility model relates to a ventilator for pressurizing long ventilation ducts. The ventilator is mainly composed of a motor (1), a wind wheel (2), an air inlet (3), an air outlet (4), a housing (5), a side plate (6), etc., wherein, the bases (7) of the air inlet and (or) the air outlet form a step surrounding the air inlet and the air outlet and approximately presenting a square shape; the tails (8) present a circular shape to form cylindrical shapes with square close ends and circular far ends. The utility model has the advantages of reasonable structure and convenient operation and is suitable for pressurizing the long ventilation ducts.
Description
The utility model relates to a kind of ventilation equipment, particularly a kind of ventilator that is used for the ventilation duct pressurization, promotes ventilation.
Modern heavy construction often needs to carry ventilation by pipeline, causes underpressure not reach good ventilation effect owing to pipeline is long, at this moment just need add a ventilator in the longer pipe road, to keep enough blast, reaches the purpose of ventilation.But what have ventilator now is generally straight cylindrical into and out of the air port, and its space is narrow and small, is installing, is being difficult to when plugging into pipeline operation.
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of ventilator easy for installation is provided.
Task of the present utility model is finished like this.Ventilator mainly is made up of motor (1), wind wheel (2), intake grill (3), exhaust outlet (4), casing (5), side plate (6) etc., intake grill and (or) base portion (7) of exhaust outlet forms one around the step that roughly is square into and out of the air port, afterbody (8) is rounded, becomes the tubular of near-end side, distal circles.
Fig. 1 is a main structure schematic representation of the present utility model.
Fig. 2 is a stereogram of the present utility model.
The utility model is described in further detail below in conjunction with drawings and Examples.
The ventilation function of ventilator must be by realizing in it plugs into ventilation duct into and out of the air port.For making circular pipe with more smooth and easy into and out of being connected of air port, can form one at base portion around the step that roughly is square into and out of the air port into and out of the air port, the latter extends into circle to the far-end afterbody, thereby makes the tubular that becomes near-end side, distal circles into and out of the air port.Circular ventilation duct (9) directly with join into and out of the air port circle.Because the formation of the square step of base portion makes into and out of the space, air port to increase, installing, having when plugging into ventilation duct bigger operating space.
Rational in infrastructure, the easy-to-operat of the utility model is suitable for the pressurization of long ventilation duct.
Claims (1)
1, a kind of ventilator mainly is made up of motor (1), wind wheel (2), intake grill (3), exhaust outlet (4), casing (5), side plate (6) etc., it is characterized in that intake grill and (or) base portion (7) of exhaust outlet forms one around the step that roughly is square into and out of the air port, afterbody (8) is rounded, becomes the tubular of near-end side, distal circles.
