Description

Technical Field

[0001] This utility model relates to the field of air outlet application technology, specifically an adjustable air outlet for cleanrooms. Background Technology

[0002] Cleanrooms, as special spaces with strict requirements for environmental cleanliness, temperature, humidity, and pressure, are widely used in many fields with extremely high requirements for the production environment, such as electronics, pharmaceuticals, food, and bioengineering. In these fields, product quality and the stability of the production process are closely related to the environmental control of the cleanroom. As a key component of the cleanroom air supply system, the performance of the air outlet directly affects the overall environmental quality of the cleanroom. Traditional cleanroom air outlets are mostly fixed structures, and their parameters such as air supply angle and air volume are difficult to adjust flexibly after installation. In actual cleanroom operation, different production processes and working scenarios may require different air supply modes. Therefore, we propose an adjustable air outlet for cleanrooms. Utility Model Content

[0003] The purpose of this invention is to provide an adjustable air outlet for cleanrooms to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an adjustable air outlet for cleanrooms, comprising a filter housing, a second air outlet assembly, and a first air guide assembly. One end of the filter housing is equipped with a first air inlet pipe and a second air inlet pipe, and the other end of the filter housing is equipped with a first air outlet assembly and a second air outlet assembly. The air outlet draws in external air through the first and second air inlet pipes, filters and purifies it within the filter housing, and then delivers clean air into the cleanroom through the adjustable first and second air outlet assemblies. Furthermore, the air intake can be adjusted according to the actual needs of the cleanroom. The relevant parameters of the air output can be flexibly adjusted. The first air output component and the second air output component are respectively installed at the air outlet of the first air output component and the second air output component. A PLC controller is fixed on one side wall of the filter box. The PLC controller is electrically connected to the first air output component, the second air output component, the first air output component and the second air output component. Through preset programs, the air output volume and air output speed of the first air output component and the second air output component can be precisely controlled. The air output direction of the first air output component and the second air output component can also be adjusted to meet the diverse needs of different areas in the clean room for air flow and direction.

[0005] Preferably, a first coarse filter and a second coarse filter are installed on one side of the filter housing, and an activated carbon filter structure is installed on another side of the filter housing. A first adsorption fan and a second suction fan are installed inside the filter housing. The first and second coarse filters are mainly used to perform preliminary filtration on the external air drawn in through the first and second air intake pipes, intercepting larger dust and impurities to reduce the burden on subsequent filtration structures. The activated carbon filter structure can further adsorb odors, harmful gases, and fine particles in the air, improving air cleanliness. The first adsorption fan and the second suction fan work together. The first adsorption fan is responsible for adsorbing the air after coarse filtration and activated carbon filtration into a specific area inside the filter housing, while the second suction fan accelerates the treated air towards the first and second air outlet components, ensuring that the air can enter the cleanroom efficiently and stably.

[0006] Preferably, the first adsorption fan and the second adsorption fan are arranged side by side at the air outlet of the filter box along the airflow direction. The first adsorption fan and the second adsorption fan are located behind the activated carbon filter structure. After the air is fully purified by the activated carbon filter structure, it can be immediately and efficiently adsorbed by the first adsorption fan to a specific area. Then, the second adsorption fan can quickly push the treated air to the air outlet component, avoiding the retention of air in the filter box and secondary pollution. At the same time, this side-by-side arrangement can also balance the air pressure to a certain extent, ensuring the uniformity and stability of the air outlet, and further improving the quality and cleanliness of the air delivered into the clean room.

[0007] Preferably, the second air outlet assembly is equipped with an air outlet pipe. One end of the air outlet pipe is fitted with a rectangular fixing plate via a metal flexible hose, and the other end is fitted with an annular fixing plate. A flange is installed on the side wall of the air outlet pipe. The air outlet pipe is made of corrosion-resistant, high-strength material to ensure it will not be damaged by trace amounts of corrosive substances in the air during long-term use, and can withstand certain pressure changes. The rectangular fixing plate has multiple mounting holes, allowing it to be securely fixed to the cleanroom wall or a designated installation location using bolts, ensuring the stability of one end of the air outlet pipe. The annular fixing plate is used to connect to subsequent ventilation ducts or other equipment; its inner diameter matches the outer diameter of the air outlet pipe, and the connection is sealed to prevent air leakage.

[0008] Preferably, the first air guiding component is equipped with an air guiding pipe, the lower end of which is equipped with a solenoid valve, and the upper end of which is equipped with an air outlet hood via a connecting disc. The air guiding pipe is made of high-quality metal material, which has good air guiding performance and a certain pressure resistance, ensuring the stability and smoothness of air during transmission. The solenoid valve can precisely control the air flow in the air guiding pipe and flexibly adjust the air delivery according to the actual needs of the cleanroom, achieving precise control of the air supply volume. The connecting disc plays a role in stabilizing the connection, tightly connecting the air outlet hood to the air guiding pipe, ensuring the sealing of the connection and preventing air leakage.

[0009] Compared with the prior art, the beneficial effects of this utility model are: This utility model features an exhaust pipe with flanges mounted on its side walls. The exhaust pipe is made of corrosion-resistant, high-strength material to ensure it will not be damaged by trace amounts of corrosive substances in the air during long-term use, while also withstanding certain pressure changes. A rectangular fixing plate has multiple mounting holes, allowing it to be securely fixed to the cleanroom wall or a designated installation location using bolts, ensuring the stability of one end of the exhaust pipe. An annular fixing plate is used for connection to subsequent ventilation ducts or other equipment; its inner diameter matches the outer diameter of the exhaust pipe, and the connection is sealed to prevent air leakage.

[0010] The first and second coarse filters of this invention are mainly used to perform preliminary filtration of external air drawn in through the first and second air intake pipes, intercepting larger dust and impurities to reduce the burden on subsequent filtration structures. The activated carbon filter structure can further adsorb odors, harmful gases and fine particles in the air, improving air cleanliness. The first adsorption fan and the second suction fan work together. The first adsorption fan is responsible for adsorbing the air after coarse filtration and activated carbon filtration into a specific area inside the filter box, while the second suction fan accelerates the treated air towards the first and second air outlet components, ensuring that the air can enter the cleanroom efficiently and stably.
