Description

Technical Field

[0001] This utility model relates to the field of ventilator technology, and more specifically to a ventilator for extending ventilation ducts. Background Technology

[0002] Factory roof ventilators are widely used for smoke and dust extraction in industrial workshops. They rely on natural wind pressure or thermal pressure to drive the blades to rotate, expelling indoor smoke, dust, and high-temperature gases. Traditional ventilators are installed directly on the roof, relying on smoke and dust to rise naturally to the roof and be drawn in.

[0003] However, in existing technologies, smoke and dust in tall factory buildings tend to diffuse and cool during the upward process, making it difficult to reach the roof ventilator. Furthermore, the suction area is small, and smoke and dust particles in the factory building float in mid-air, resulting in low smoke exhaust efficiency. Metal ventilation ducts are heavy, complex to install, and cannot be adapted to the factory building structure.

[0004] Therefore, there is an urgent need to design a lightweight ventilation duct system with an extended suction distance, which can set the duct length according to the height of the factory building, improve the smoke and dust emission area and efficiency of tall factories, and have fireproof and low-energy consumption driving functions. Utility Model Content

[0005] This invention provides a ventilator that extends the ventilation duct to solve the problems existing in the prior art.

[0006] To achieve the above objectives, this utility model provides a ventilator extension ventilation duct, comprising: a ventilator, with a ventilation duct fixedly connected to the lower part of the ventilator; the ventilation duct having multiple annular interlayers evenly distributed along its outer circumference, with a keel provided in the interlayer to maintain the shape of the ventilation duct; and the ventilation duct having multiple through holes for adsorbing smoke and dust particles near the ventilation duct.

[0007] Preferably, the ventilator includes a base, the base is fixed to the ventilator cylinder by multiple screws, a bracket is connected to the cylinder and a bearing is connected to it, the bearing is mounted on a central rod, multiple blades are arranged sequentially on the edge of the bracket, and a top cover is provided at the top of the blades.

[0008] Preferably, the ventilation duct is made of fireproof cloth.

[0009] Compared with the prior art, the present invention has the following advantages:

[0010] The ventilation duct has an annular interlayer around its outer circumference with an internal keel. Combined with the duct structure (upper and lower fireproof cloth wrapping layers, with a keel in the middle), the keel effectively maintains the duct's shape and angle, preventing deformation due to external forces or high temperatures. The fireproof cloth wrapping layer blocks the spread of fire. Even if the factory is emitting smoke, the duct maintains its structural integrity, ensuring unobstructed smoke and dust transmission and allowing the ventilator to effectively extract smoke and dust.

[0011] The ventilation ducts have multiple through-holes. Since smoke and dust particles in the factory are suspended in mid-air, the through-holes draw in and remove these particles from both the duct openings and the outer walls of the duct. When natural ventilation is insufficient or smoke and dust accumulate, this design enhances exhaust efficiency, rapidly removes smoke and dust particles, improves air quality, and adapts to various operating conditions, especially scenarios requiring strong exhaust ventilation, such as when the factory is emitting smoke.

[0012] The overall structural design is optimized for working conditions such as smoke in the factory, solving the exhaust problems of traditional ducts and ventilators in this scenario. The simple structure enables the ventilation system to operate stably in complex environments, meeting the long-term and diverse ventilation needs of the factory and improving the reliability and practicality of the factory ventilation system.

[0017] To facilitate understanding by those skilled in the art, various embodiments of this patent will be described below with reference to text and accompanying drawings. For clarity, many practical details will be explained in the following description. However, it should be understood that these practical details in the specification should not be used to limit this patent. That is, in some embodiments of this patent, these practical details are not essential. Furthermore, for ease of understanding, some conventional structures and components will be illustrated in the drawings in a simple schematic manner.

[0018] In the description of this patent, it should be understood that the terms "length", "width", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this patent and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this patent.

[0019] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this patent, "a plurality of" means two or more, unless otherwise explicitly specified.

[0020] In this patent, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this patent according to the specific circumstances.

[0021] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this patent.

[0022] Please see the appendix Figure 1-2 A ventilation duct extension method for a ventilator is disclosed, comprising: a ventilator 1, a ventilation duct 2 fixedly connected to the lower part of the ventilator 1, the ventilation duct 2 having a plurality of annular interlayers 5 evenly arranged along the outer circumference, the interlayers 5 having a keel 4, the two forming an annular support circular skeleton, which can maintain the shape of the ventilation duct 2; the ventilation duct 2 having a plurality of through holes 3 for adsorbing smoke and dust particles near the ventilation duct, the ventilation duct 2 being made of fireproof cloth.

[0023] To further optimize the above technical solution, the ventilator 1 includes a base, which is fixed to the ventilator cylinder by multiple screws. A bracket 10 is connected to the cylinder and a bearing is connected to it. The bearing is mounted on a central rod. Multiple blades are arranged sequentially along the edge of the bracket, and a top cover is provided at the top of the blades.

[0024] In use, the stainless steel ventilator is installed on the factory roof, with the keel 4 evenly embedded in the annular interlayer 5 around the ventilation duct on the base. The ventilator base 1 is then connected to the top of the duct, and the joint is sealed.

[0025] Specifically, when external natural wind enters the ventilator 1, it drives the blades to rotate around the slip ring, and the top cover guides the airflow upward to create a negative pressure zone, which in turn drives the airflow inside the duct. The through holes on the duct can suck away smoke and dust particles near the ventilation duct opening and near the outer wall of the duct. The keel 4 supports the ventilation duct 2 to prevent the duct from deforming due to gravity or wind pressure; the fireproof cloth blocks external high temperatures and protects the structural integrity.
