Abstract

The utility model relates to a powerful exhaustion ventilator which comprises a ventilator framework, a ventilation duct and an exhaust fan, wherein the upper part of the ventilator framework takes an arc shape, and the lower part thereof adopts a triangular structure; the ventilation duct is arranged in the ventilator; and the exhaust fan is arranged at the lower part of an inlet of the ventilation duct. Compared with the prior art, the exhaust fan is additionally arranged at the opening of the duct in the ventilator provided by the utility model, so that the exhaust fan generates powerful exhaustion while natural ventilation, thereby increasing the exhaust air rate of the ventilator. The powerful exhaustion ventilator is suitable for factory buildings with heavy dust and smaller ventilation openings, and has the advantages of convenient installation, convenient operation and lower cost.

Description

A kind of forced-ventilated wind ventilator

Technical field

The utility model relates to a kind of ventilator, especially relates to a kind of forced-ventilated wind ventilator.

Background technology

Before the last century the nineties, the ventilating skylight of China's industrial premises generally adopts rectangle ventilating skylight and sunk type ventilating skylight.The rectangle ventilating skylight generally is made up of skylight frame, deep bead, weather shield, roof boarding, and the coefficient of air resistance of aditus laryngis is 4.5～6, and ventilation is little, and complex structure is from great, unfavorable to antidetonation; The sunk type ventilating skylight is the space that utilizes the height part of roof truss, the part roof boarding is placed on the lower edge of roof truss, the resistance coefficient of aditus laryngis is also about 4.5～6, ventilation is little, on the roof truss, all there is moment of torsion in lower edge, member section is big, easy dust stratification, and draining is handled complicated, the sash complex structure, and the development need of incompatibility modern light steel-structure factory building, and all unpowered equipment of ventilating opening, some special occasions, unpowered ventilation equipment might be able to not satisfy the eliminating of factory building dust, or intrinsic ventilator is less in the factory building, and the air draft requirement that ventilation can't satisfy factory building does not utilize production.

Summary of the invention

The purpose of this utility model is exactly that a kind of simple installation, forced-ventilated wind ventilator simple to operate are provided in order to overcome the defective that above-mentioned prior art exists.

The purpose of this utility model can be achieved through the following technical solutions:

A kind of forced-ventilated wind ventilator, it is characterized in that, this forced-ventilated wind ventilator comprises ventilator skeleton, ventilation shaft and exhaust blower, described ventilator skeleton top be shaped as arc, bottom structure triangular in shape, described ventilation shaft is located in the ventilator, and described exhaust blower is located at the bottom of ventilation shaft import.

Described exhaust blower comprises blower fan fixed bar, elbow, horn mouth and flashing plate, described blower fan fixed bar is connected on the ventilator skeleton, described elbow is located on the blower fan fixed bar, and described horn mouth is located at the elbow bottom, and described flashing plate is located at the lower end of ventilator skeleton.

Compared with prior art, the utility model is by being provided with exhaust blower on the pipeline opening of ventilator, make it in gravity-flow ventilation, produce powerful air draft by exhaust blower, strengthened the exhaust air rate of ventilator, the factory building that suitable dust is heavier and ventilating opening is less uses, and easy for installation, easy to operate, and cost is also lower.
