Abstract

The utility model relates to a spraying conduction type ventilation device, and consists of an air inlet opening, a sound damper, a conducting body, a motor, a streamline shaped nozzle, a hub cap, a tail cap and a hanging arm; an impeller is driven by the motor, to generate high speed jet flow, to induce and absorb the ambient air, and form directed air current under the function of a jet fan, the utility model is used to replace a pipeline, thereby reducing the course height, the streamline shaped nozzle is used, thereby reducing the fluid motion resistance, and reducing the noise generated because of turbulent flow; the hanging arm is also equipped with a rotating device which can be adjusted in the horizontal direction and the vertical direction, the sound damper can lead the noise to be 49 DB, and the hub cap and the tail cap can reduce the fluid resistance.

Description

Spray the drainage type ventilation unit

(1) technical field: the utility model relates to a kind of injection drainage type ventilation unit, belongs to ventilation, air-conditioning technical field.

(2) background technology: the draft type of traditional underground garage is duct type row, air-supply.The pipeline that calculates according to the ventilation rate of reality, usually has significant volume, occupy the very big useful space of building, increase with the automobile demand amount, build a large amount of underground garages, for effectively utilizing the space, reduce the floor height in garage greatly, but conventional pipelines can't satisfy this kind situation.As the minimum clear height in garage be 2.2m, and the floor height in now a lot of garages is 2.5m～2.8m, if again pipe laying then clear height will be less than 2.2m, so need new technology solve.

(3) summary of the invention:

Structure of the present utility model shown in Fig. 1-6, by air inlet (3), muffler (14), baffle (8,11,12) motors (13), streamlined spout (15) hubcap (25), hood (26) and arm (16～24) constitute; Tubular motor block set (12) is arranged among annular cylinder shape baffle pedestal (8), between baffle pedestal (8) and motor block set (12), there is radially equally distributed guide vane (11) three to be connected as a single entity, motor (13) sets in motor block set (12), motor shaft (30) is overhanging from the central axis hole of motor block set (12), on overhanging motor shaft (30), set draught fan impeller (10), on the same axis of draught fan impeller (10) front end, hubcap (25) is housed, on the extended line of the same axle of holding in addition of motor (30), set hood (26), baffle pedestal (8) two ends ring flange is connected with two ends muffler (14) with axle bolt (9), the device front end is equipped with tubaeform air inlet (3), horn mouth is equipped with protecting wire net (2) and is fastened on the air inlet (3) with bolt (1), air inlet (3) is anchored on the muffler (14) with bolt (4), there is the streamlined spout (15) of a cross section convergent device rear end, with bolt (4) tightening on muffler (14), more than device is lifted on top of building with arm, there is bolt (20) the arm upper end, on turn to groove (21), turn to bolt (22), the horizontal direction rotation, direction is adjustable; The arm lower end is fixed on the water conservancy diversion pedestal (8), turns to bolt (24), and side turns to groove (23), does the vertical direction rotation, adjustable angle.

The utility model is induced and is entrainmented surrounding air by the high-speed jet of jet blower, makes it to form windstream under the jet blower effect, make it to replace pipeline, reduce floor height and adopt the streamlined spout, reduced the fluid motion resistance, reduce the noise that produces owing to turbulent flow.Arm is provided with whirligig again can do horizontal direction and vertical direction adjustment, to solve the characteristics that are not easy to adjust that exist in traditional arm mode.Muffler can make noise reach 49DB, and hubcap and hood can improve the effect that air-flow enters blade, and hood helps the air-flow diffusion.
