Description

Fi d. 1

The invention relates to the field of ventilation and can be used in supply air ventilation systems for various premises.

Known air distributor, comprising a housing with an exhaust window, installed at the exit of it swivel shields with articulated: nmm t gami and the mechanism of rotation of the shields, including a drive mounted on his wave worms and interacting with the last gears.

This air distributor provides some turbulence in the outflowing air flow (through the installation and rotation of the flaps), and, accordingly, the degree of mixing of the incoming air with the internal air changes. Some regulation of the degree of turbulence of the flow can be achieved by changing the speed of rotation of the plates.

The disadvantages of the air distributor are the insignificant range of regulation of the degree of mixing of the supply air with the internal air, as well as the fact that additional energy is required to drive the plates, which reduces the efficiency of the device.

Closest to the invention is an air distributor containing an inlet nozzle, movably fixed on it with longitudinal slots and arcuate slots adjacent to them, a horizontal axis located under the nozzle, the ends of which are located in the slots of the suspensions with the possibility of moving along the longitudinal slots and arc-shaped grooves placed on the horizontal axis of the flow turbulator, consisting of two diametrical blades.

In the known air distributor, no additional energy is required for the drive to drive the flow turbulator, which increases its efficiency. Regulation of the degree of turbulence, and accordingly, the degree of mixing of the supply air with the internal air can be achieved by changing the position of the parts of the turbulator relative to each other, as well as the entire turbulator along the height of the suspensions. However, this is not enough to ensure normalized parametrosis of air in the working (serviced) area of the room, as the range of regulation of the degree of mixing of the incoming air with the internal air is insufficient.

The purpose of the invention is to expand the range of regulating the degree of mixing of the supply air with the internal air.

This goal is achieved by the fact that a plenum distributor containing a supply pipe, movably mounted on it vertical podieski with longitudinal slots and arcuate grooves adjacent to them, located under the branch pipe of a horizontal axis, the ends of which are located in the slots of the suspensions with the possibility of moving along the longitudinal slots and arcuate grooves. placed on the horizontal axis of the flow turbulator, consisting of two diametrical blades, the flow turbulent is equipped with radial blades located on both sides of the diametrical blades connected to them with the formation of a star-shaped impeller in cross section, with the latter being spliced around it under the action of the jet flowing out of the nozzle, and the extra sand is attached to the nozzle with the possibility of rolling.

Figure 1 shows the air distributor, General view; figure 2 is the same, side view; on FIG. 3 — node I in FIG. 2: in FIG. 4 — view A. in FIG. 2; figure 5 is a section bB in figure 2.h

The air distributor contains inlet pipe 1, vertical suspensions 2 movably fixed on it with longitudinal slits 3 v, arc-shaped grooves 4 adjoining them, horizontal axis 6 located below branch pipe 1, whose hints are arranged in slots 3 of suspensions 2 with movement along longitudinal of the slots 3 and of the arc-grooves of the slots A, placed on the horizontal axis b of the flow turbulatory 5, consisting

of two diametrical blades. During this period, the turbulizer 5 of the flow is provided with 4 mm radial blades located along the side of the diametrical blades connected to them with the formation of an impeller 7 in a cross section of the impeller 7. The impeller is placed on the horizontal axis 6 with the possibility of free rotation around it under the action of nozzle 1 jet.

The suspensions 2 are attached to the socket 1 with the possibility of tangling (with the possibility of angular rotation in the vertical plane) and securing with the help of, for example, cap nuts 11. The horizontal axis b is located

wife and secured in the working position in the grooves 4 suspension 2, for example, with Pondyu nuts 9.

Air spr .: de .-. Itol. works as follows.

The intake air enters the inlet pipe 1 and then as far as the exit window 8 into the room. A stream of air flowed under the pipe 1 with the free rotation around the horizontal axis b of the impeller 7. brings it into rotational movement from the horizontal axis 6, which is located and fixed in the working position in the slots 4 of the suspension 2. Rotating the impeller 7 The turbulent jet is significantly turbulent, which later quenches its speed much faster. Swinging (angular rotation) of suction 2 with impeller 7 in a vertical plane around the hinged connection 10 of the platform 2 with F-SOX HO pipe 1, change the position of the impeller 7 on the inlet stream and thereby adjust the degree of mixing of the inlet air with the inner one. If necessary, you can completely remove the impeller 7 from under the jet, not to produce artificial turbulization of the jet and thus preserve its natural degree of mixing with the indoor air of the room. By longitudinal movement of the impeller 7 relative to the bottom 2 by moving the legal axis 6 in the slot 3, it is also possible to adjust the position of the impeller in the inlet stream and regulate the degree of streaming and the degree of its mixing with the indoor air in the room. It should be noted that in the proposed air distributor, no additional energy is required for driving the turbulator in motion, which ensures efficiency of the device.

Thus, the effectiveness of the invention lies in expanding the range

to regulate the degree of mixing of supply air with internal air, in regulating the speed and temperature of the air flow that is supplied to workplaces, and, consequently, in improving sanitary and hygienic working conditions by regulating the degree of turbulence of the jet by adjusting the position of the freely rotating impeller under the action of the outflowing jet (without the approach of additional external energy nz drive the impeller).
