Description

An energy-saving ventilation device

technical field

The utility model relates to the technical field of indoor ventilation, in particular to an energy-saving ventilation device.

Background technique

At present, most of the ventilation in factories or indoors with a large area is carried out by exhaust fans installed on the wall. The exhaust fans driven by motors consume a lot of electricity and have poor ventilation effects.

Although there are also turbine-type roof exhaust fans installed, which can achieve a better ventilation effect, but the power consumption is large and not energy-saving.

Utility model content

In order to solve the above technical problems, the technical solution adopted by the utility model is: an energy-saving ventilation device, including an air supply pipeline, one end of the air supply pipeline communicates with the room, the other end of the air supply pipeline communicates with the airflow pipeline, and the airflow pipeline One end is provided with a wind collector, and the other end of the airflow duct is an air outlet.

Further, the airflow duct is provided with an empennage at the air outlet through an empennage support rod, and the air supply duct includes an inner air supply duct and an outer air supply duct, the inner air supply duct is arranged in the wall, and the outer air supply duct is rotatable relative to the inner air supply duct .

A speed-increasing baffle is arranged inside the airflow pipeline at the connection with the air supply pipeline.

An exhaust fan is arranged in the air supply duct.

The connection between the air collector and the airflow duct adopts a smooth transition of a curved surface.

Compared with the prior art, the utility model has the following advantages: use the outside wind to enter the air collector of the ventilation device to generate a pressure difference, suck out the gas in the room, and use the wind energy to perform ventilation, saving energy and reducing costs.

The following is a brief description of the content expressed in the drawings of this manual and the marks in the drawings:

Figure 1 is a schematic diagram of the structure of the ventilation device of the present invention.

In the figure: 1. Air collector, 2. Airflow duct, 3. Empennage, 4. Empennage support rod, 5. Speed-up baffle, 6. External air supply pipe, 7. Rotary shaft, 8. Exhaust fan, 9. Inner air duct.

Detailed ways

The specific implementation of the present utility model will be described in further detail below by describing the embodiments with reference to the accompanying drawings.

As shown in Figure 1, the energy-saving ventilation device includes an air supply pipeline and an air collector 1; the air supply pipeline includes an internal air supply pipeline 9 and an external air supply pipeline 6 that are connected, the internal air supply pipeline 9 is located in the wall, and the external air supply pipeline 9 is rotatable relative to the internal air supply pipeline 6. Preferably, the external air supply pipeline 6 is connected to the wall at the internal air supply pipeline through the rotating shaft 7, and a translational thrust bearing is provided at the connection between the external air supply pipeline 6 and the wall; The outer end of the pipe 6 communicates with the middle part of the horizontally arranged airflow pipe 2; the air collector 1 has a large opening at one end and a small opening at the other end. The connection between the air collector and the airflow duct adopts a smooth transition of a curved surface; the other end of the airflow duct 2 is an air outlet.

An empennage 3 is provided at the air outlet of the airflow duct 2 through an empennage support rod 4, preferably, the empennage 3 is a vertical plate.

A protruding speed-increasing baffle 5 is provided at the connection with the external air-supply pipe in the air-flow pipe 2, and the speed-increasing baffle 5 is arranged between the external air-supply pipe and the wind collector.

And exhaust fan 8 is installed in the air delivery pipeline 9, when wind-force is weaker, start exhaust fan 8 work, carry out indoor ventilation.

When installing the ventilation device, at first the corresponding installation opening should be dug out on the top of the existing factory building, or the installation opening should be reserved when the factory building is being built, and the energy-saving ventilation device of the present utility model should be installed on the installation opening. Entering the air collector, the speed increases at the speed-increasing baffle, and the indoor air pressure is greater than the air outlet air pressure, so the indoor air is drawn out, and the wind energy is used to ventilate the room, saving energy and reducing costs.

The utility model has been exemplarily described above in conjunction with the accompanying drawings. Obviously, the specific implementation of the utility model is not limited by the above-mentioned method, as long as various insubstantial improvements made by the idea and technical solutions of the utility model are adopted, or there is no Those who directly apply the idea and technical solution of the utility model to other occasions through improvement are within the protection scope of the utility model.
