Description

Technical Field

[0001] The utility model relates to the technical field of building ventilation, in particular to a ventilation energy-saving device for buildings. Background Technique

[0002] Ventilation equipment is used to realize the exchange of air inside and outside the building, so as to convey fresh air into the interior space of the building to improve the comfort of the people inside the building. At present, a non-powered wind cap is set to discharge hot air, dirty oil fume and other gases in the building interior, which has the effect of ventilation and energy saving. However, due to the influence of natural wind, its use effect is limited and it is difficult to meet the ventilation requirements of the building. Content of the Utility Model

[0003] The purpose of the utility model is to provide a ventilation energy-saving device for buildings, aiming to solve the problems mentioned in the above background technique.

[0004] To achieve the above purpose, the utility model adopts the following technical scheme: the ventilation energy-saving device for buildings includes a base, and a lampblack filtering component is arranged on the base. The lampblack filtering component includes a filtering cavity arranged at the upper end of the base and connected to the base in a through manner. A metal filter screen is arranged at the inner top of the filtering cavity. The metal filter screen is arc-shaped. An annular material receiving groove is arranged inside the filtering cavity. A three-way pipe is arranged on the filtering cavity. The three-way pipe has a vertically arranged upper port and a horizontally arranged side port. A non-powered wind cap is arranged at the upper port of the three-way pipe, and a centrifugal fan is arranged at the side port of the three-way pipe. Check valve groups are arranged inside the upper port and the side port of the three-way pipe.

[0005] Preferably, the check valve group is composed of a plurality of Tesla valves.

[0006] Preferably, support feet are arranged at both the side port and the upper port of the three-way pipe.

[0012] Figure 2 It is a schematic diagram of the centrifugal fan in a specific embodiment of the present utility model.

[0014] The following further describes the specific embodiments of the present utility model with reference to the accompanying drawings.

[0015] As Figure 1-2 shown, a ventilation and energy-saving device for buildings includes a base 1. A lampblack filtering component is arranged on the base 1. The lampblack filtering component includes a filter chamber 2 arranged at the upper end of the base 1 and connected to the base 1 in a through manner. A metal filter net 3 is arranged on the inner top of the filter chamber 2. The metal filter net 3 is arc-shaped. An annular material receiving groove 4 is arranged inside the filter chamber 2. A three-way pipe 5 is arranged on the filter chamber 2. The three-way pipe 5 has a vertically arranged upper port and a horizontally arranged side port. A power-free wind cap 6 is arranged at the upper port of the three-way pipe 5. A centrifugal fan 7 is arranged at the side port of the three-way pipe 5. Check valve groups 8 are arranged inside both the upper port and the side port of the three-way pipe 5.

[0016] The base 1 is arranged at the exhaust port of the building and is fixed to the building by bolts. In the upward-flowing air in the building, after the gas containing more lampblack passes through the metal filter net 3, part of the lampblack will adhere to the metal filter net 3, and through the arc-shaped structure of the metal filter net 3, it will be drained into the material receiving groove 4, thereby reducing the adhesion of lampblack on the power-free wind cap 6. Since the adhesion of lampblack will increase the rotation resistance of the power-free wind cap 6, by adsorbing part of the lampblack, the adhesion of lampblack on the power-free wind cap 6 can be reduced to improve the operation reliability of the power-free wind cap 6.

[0017] When the power-free wind cap 6 can rotate under the action of natural wind, the gas in the building can be pumped out. Under the action of atmospheric pressure, fresh air enters the building interior. Since the check valve groups 8 at both the upper port and the side port of the three-way pipe 5 can prevent external air from entering the building interior through the three-way pipe 5, the power-free wind cap 6 can only pump out the gas in the building, and the external air cannot be pumped out by the power-free wind cap 6 through the side port of the three-way pipe 5, so that the power-free wind cap 6 can ventilate the building accurately and efficiently.

[0018] When the external natural wind is not sufficient to rotate the non-powered wind cap 6, the centrifugal fan 7 is started. The centrifugal fan 7 extracts the gas inside the building. Due to the one-way valve group 8 at the upper port of the tee pipe 5, the centrifugal fan 7 can extract the gas inside the building, and the external air cannot be extracted by the centrifugal fan 7 through the upper port of the tee pipe 5. The provided centrifugal fan 7 can play a role in ventilation when the non-powered wind cap 6 cannot work effectively. When the non-powered wind cap 6 can work normally, the centrifugal fan 7 can be suspended or used together with the non-powered wind cap 6.

[0019] Further, the one-way valve group 8 is composed of multiple Tesla valves. The multiple Tesla valves close the channels of the upper port and the side port of the tee pipe 5, enabling the gas to flow only through the channels in the Tesla valves.

[0020] Further, support feet 9 are provided at both the side port and the upper port of the tee pipe 5. The support feet 9 are used to support the tee pipe 5, thereby reducing the pressure exerted by the tee pipe 5 on the filter chamber 2 and facilitating the removal of the filter chamber 2 from between the base 1 and the tee pipe 5. After removing the filter chamber 2, the metal filter screen 3 and the material receiving groove 4 inside the filter chamber 2 can be cleaned to reduce the resistance when air passes through the metal filter screen 3.

[0021] Further, compressible gaskets 10 are respectively provided on both sides of the filter chamber 2. The gaskets 10 can increase the sealing performance of the filter chamber 2 between the base 1 and the tee pipe 5, so as to achieve a better ventilation effect through the non-powered wind cap 6 and the centrifugal fan 7.

[0022] Further, a handle 11 is provided on one side of the filter chamber 2, facilitating the control of the movement of the filter chamber 2 through the handle 11.

[0023] When the non-powered wind cap 6 can be used normally under the action of natural wind, the ventilation requirements of the building can be achieved through the non-powered wind cap 6. And since the non-powered wind cap 6 does not consume electricity, it has a good energy-saving effect. When the non-powered wind cap 6 cannot be used normally under the action of natural wind, the provided centrifugal fan 7 can continue to keep the building ventilated. The centrifugal fan 7 can assist the non-powered wind cap 6 to meet the ventilation requirements of the building, and the use effect is good.

[0024] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "installation", "connection", and "connection" shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
