Description

Technical Field

[0001] This utility model relates to the field of swirl exhaust terminal technology, and in particular to a swirl exhaust terminal for large spaces. Background Technology

[0002] In modern architectural and industrial production environments, air quality control is crucial for ensuring indoor comfort and human health. Large spaces such as factory workshops, stadiums, and exhibition halls, due to their vast size and high population density, place higher demands on air circulation and pollutant emissions. Especially in these places, frequent personnel activity and continuous equipment operation generate large amounts of heat, moisture, smoke, dust, and other pollutants that disperse rapidly. Without efficient air circulation and exhaust systems, air quality can deteriorate sharply, impacting worker health and even causing accidents. Therefore, effectively controlling air quality in these large spaces, preventing the accumulation of harmful gases, and providing a clean, pollution-free air environment have become core tasks in design and operation.

[0003] In existing technology, most industrial exhaust fans on the market consist of a single fan and a casing of a corresponding size. Once started, they can only operate at the motor's maximum speed. The problem is that because it's just a single fan, it can only create negative pressure in a small area around the fan's circular perimeter. This small negative pressure zone results in slow airflow at the top, limited turbulence, and a small percentage of polluted air being expelled. Under these conditions, operating at maximum speed leads to significant heat loss and energy waste during the heating season.

[0004] Therefore, those skilled in the art have provided a swirl exhaust terminal for large spaces to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a vortex exhaust terminal for large spaces. This structure, under the control of the control box, allows the vortex introduction system to form a vortex negative pressure ring. This negative pressure ring is linear and perpendicular to the air outlet, with a long length, which can accelerate the turbulence of polluted air and then exhaust it. At the same time, the control box can adjust the fan speed, thereby affecting the amount of heat loss in the space and avoiding energy waste.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A large-space vortex exhaust terminal includes a housing, an exhaust port at the upper end of the housing, an intake port at the lower end of the housing, a fan at the upper interior of the housing, a drive ring at the lower interior of the housing, guide vanes evenly spaced at the lower end of the drive ring, a drive shaft at one end face of one of the guide vanes, an actuator at the lower interior of the housing, and a control box at one end face of the housing.

[0008] Through the above technical solution, the structure adopts a swirling negative pressure ring formed by the swirling introduction system under the setting of the control box. The negative pressure ring is linear and perpendicular to the air outlet, and has a large length, which can accelerate the turbulence of polluted air and then discharge it. At the same time, the control box can adjust the speed of the fan, thereby affecting the amount of heat loss in the space and avoiding energy waste.

[0009] Furthermore, the drive shaft is connected to the actuator;

[0010] Through the above technical solution, the connection between the drive shaft and the actuator can achieve precise control and efficient operation of the actuator, ensuring that the entire system operates more stably and efficiently.

[0011] Furthermore, the fan is located at the lower end of the exhaust port;

[0012] With the above technical solution, the fan is located at the lower end of the exhaust port, which can improve the efficiency of the fan, ensure smooth air circulation, avoid dead air zones, optimize the air exhaust path, thereby effectively improving the exhaust effect and reducing energy waste.

[0013] Furthermore, the exhaust port, fan, drive ring, and intake port are all located at the center of the housing and remain coaxial.

[0014] By aligning the exhaust vent, fan, drive ring, and intake vent coaxially using the above technical solution, we can ensure uniform airflow distribution, reduce the tortuosity and resistance of the airflow path, and thus improve the overall ventilation efficiency of the system.

[0015] This utility model has the following beneficial effects:

The negative pressure ring is linear and perpendicular to the air outlet. It has a large length and can accelerate the turbulence of polluted air and then exhaust it. At the same time, the control box can adjust the speed of the fan, thereby affecting the amount of heat loss in the space and avoiding energy waste. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Reference Figure 1-2 The present invention provides a specific embodiment of a large-space vortex exhaust terminal, comprising a housing 9, an exhaust port 1 at the upper end of the housing 9, an intake port 7 at the lower end of the housing 9, a fan 2 at the upper end of the interior of the housing 9, a drive ring 3 at the lower end of the interior of the housing 9, guide vanes 4 evenly spaced at the lower end of the drive ring 3, a drive shaft 5 on one side end face of one of the multiple guide vanes 4, an actuator 6 at the lower end of the interior of the housing 9, and a control box 8 on one side end face of the housing 9.

[0023] Under the control box 8, the swirling introduction system can form a swirling negative pressure ring. This negative pressure ring is linear and perpendicular to the air outlet. It is long and can accelerate the turbulence of polluted air and then discharge it. At the same time, the control box 8 can adjust the speed of the fan 2, thereby affecting the amount of heat loss in the space and avoiding energy waste.

[0024] The drive shaft 5 is connected to the actuator 6. Through the connection between the drive shaft 5 and the actuator 6, the actuator 6 can be precisely controlled and operate efficiently, ensuring that the entire system operates more stably and efficiently. The fan 2 is located at the lower end of the exhaust port 1. The location of the fan 2 at the lower end of the exhaust port 1 can improve the efficiency of the fan 2, ensure smooth airflow, avoid dead airflow, optimize the air exhaust path, thereby effectively improving the exhaust effect and reducing energy waste. The exhaust port 1, the fan 2, the drive ring 3, and the intake port 7 are all located at the center of the housing 9 and kept coaxial. Aligning the exhaust port 1, the fan 2, the drive ring 3, and the intake port 7 coaxially can ensure the uniform distribution of airflow, reduce the tortuosity and resistance of the airflow path, thereby improving the overall ventilation efficiency of the system.

[0025] Working principle: When in use, this structure guides indoor air to the exhaust vent 1 through the negative pressure effect generated by the built-in fan 2. During this process, the drive ring 3 drives the transmission shaft 5 to rotate, and the guide vanes 4 on the transmission shaft 5 move synchronously to form a vortex, which enhances the power of the airflow and ensures that the air can flow to the exhaust vent 1 efficiently along the predetermined path. Through this precise airflow movement, the system can effectively realize the exhaust and ventilation of indoor air, thereby improving indoor air quality and ensuring the comfort and health safety of people.
