Description

Technical Field

[0001] This utility model relates to the field of cleanroom technology, and in particular to a ventilation structure for a Class 1000 cleanroom. Background Art

[0002] Cleanrooms, also known as clean rooms, dust-free workshops, or clean rooms, are widely used in pharmaceuticals and bioengineering, precision machinery, medical and health care, food, and electronic materials. A Class 1000 cleanroom refers to a clean environment in which the air contains no more than 1,000 particles per cubic meter. To maintain such a level of cleanliness, the design of the workshop and the air handling system must be very precise to ensure the cleanliness of the air, the stability of temperature and humidity, and the efficiency of personnel activities. The ventilation structure is a key component in ensuring the environmental quality of the cleanroom.

[0003] In the existing technology, the air exchange structure of the clean room can adjust the cleanliness of the clean room as needed through the air exchange component and the circulation component, which improves the practicality of the air exchange structure. However, it often cannot adjust the humidity of the air inside the room, and the function of the air exchange structure is relatively simple. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a ventilation structure for a Class 1000 cleanroom, aiming to improve the problem that the existing ventilation structures cannot regulate the humidity of the air inside the workshop and have a relatively limited function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a ventilation structure for a Class 1000 cleanroom, comprising a cleanroom body, a blower fixedly connected to the upper middle part of the cleanroom body, an air intake pipe fixedly connected to the input end of the blower, an air delivery pipe fixedly connected to the output end of the blower, a filter assembly provided on the upper left side of the cleanroom body, a water storage tank fixedly connected to the upper right side of the cleanroom body, a water inlet pipe fixedly connected to the upper part of the water storage tank, an air guide cavity opened on the left side of the inner wall of the cleanroom body, air guide ports opened at the top and bottom on the left side of the air guide cavity, an exhaust pipe fixedly connected to the right side of the inner wall of the cleanroom body, and a humidity regulating assembly provided on the upper part of the inner wall of the cleanroom body.

[0006] As a further description of the above technical solution:

[0007] The filtration assembly includes a filter box, which is fixedly connected to the upper left side of the workshop body. A pre-filter is fixedly connected to the bottom left side of the filter box, a medium-efficiency filter is fixedly connected to the bottom middle of the filter box, and a high-efficiency air filter is fixedly connected to the bottom right side of the filter box.

[0008] As a further description of the above technical solution:

[0009] The humidity control component includes a mounting plate, which is fixedly connected to the upper part of the inner wall of the workshop body. A humidity sensor is fixedly connected to the lower middle part of the mounting plate. A water pump is fixedly connected to the upper part of the mounting plate. A water pumping pipe is fixedly connected to the input end of the water pump. A water delivery pipe is fixedly connected to the output end of the water pump. An atomizing nozzle is fixedly connected to the end of the water delivery pipe away from the water pump.

[0010] As a further description of the above technical solution:

[0011] The end of the inlet pipe furthest from the water storage tank is fixedly connected to the water supply system.

[0012] As a further description of the above technical solution:

[0013] The end of the air intake pipe away from the blower is fixedly connected to the filter box, and the end of the air delivery pipe away from the blower passes through the workshop body.

[0014] As a further description of the above technical solution:

[0015] An air inlet pipe is fixedly connected to the left side of the filter box, and the high-efficiency air filter is a HEPA filter.

[0016] As a further description of the above technical solution:

[0017] The humidity sensor is electrically connected to the water pump, and the end of the water pump pipe away from the water pump is fixedly connected to the water storage tank.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, the water pump is started and driven to run the water pumping pipe. Water in the water storage tank is pumped into the water pump through the water pumping pipe, and then the water is transported to the atomizing nozzle through the water delivery pipe. Finally, the water is atomized and discharged into the air through the atomizing nozzle. This realizes that the ventilation structure of the Class 1000 cleanroom can regulate the humidity of the air inside the workshop, thus improving the functionality of the ventilation structure.

[0020] 2. In this utility model, the air inside the filter box is drawn into the blower by the air intake pipe driven by the blower, so that the air inside the filter box is negatively pressured and drawn into the filter box through the air intake pipe. The air is then filtered by the pre-filter, medium-efficiency filter and high-efficiency air filter to remove particulate matter in the air. Finally, the air is drawn into the blower through the air intake pipe and then into the workshop body through the air delivery pipe. This enables the Class 1000 cleanroom to fully filter particulate matter in the air and improves the practicality of the air blowing and ventilation structure of the Class 1000 cleanroom.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 1-3 This utility model provides an embodiment of a ventilation structure for a Class 1000 cleanroom, comprising a cleanroom body 1. A blower 7 is fixedly connected to the upper middle part of the cleanroom body 1. An air intake pipe 8 is fixedly connected to the input end of the blower 7, and an air delivery pipe 9 is fixedly connected to the output end of the blower 7. The end of the air intake pipe 8 away from the blower 7 is fixedly connected to a filter box 2. The end of the air delivery pipe 9 away from the blower 7 passes through the cleanroom body 1. A filter assembly is provided on the upper left side of the cleanroom body 1. A water storage tank 14 is fixedly connected to the upper right side of the cleanroom body 1. A water inlet pipe 15 is fixedly connected to the upper part of the water storage tank 14. The water inlet pipe 15 is located away from the water storage tank 1. One end of 4 is fixedly connected to the water supply system. An air guide chamber 10 is opened on the left side of the inner wall of the workshop body 1. An air guide port 11 is opened on the upper and lower left sides of the air guide chamber 10. An exhaust pipe 20 is fixedly connected to the right side of the inner wall of the workshop body 1. The filter assembly includes a filter box 2. The filter box 2 is fixedly connected to the upper left side of the workshop body 1. A primary filter 4 is fixedly connected to the bottom left side of the filter box 2. A medium-efficiency filter 5 is fixedly connected to the bottom middle of the filter box 2. A high-efficiency air filter 6 is fixedly connected to the bottom right side of the filter box 2. An air inlet pipe 3 is fixedly connected to the left side of the filter box 2. The high-efficiency air filter 6 adopts a HEPA filter.

[0028] In the air purification and circulation system of a Class 1000 cleanroom, the control and start-up of blower 7 is crucial. By starting blower 7, it not only drives the intake pipe 8 but also draws air from inside the filter box 2. During this process, a negative pressure is created inside the filter box 2, forcing external air to be drawn in through the intake pipe 3. The air first passes through the pre-filter 4, where larger particles are effectively filtered out, ensuring initial air cleanliness. Subsequently, the air passes through the medium-efficiency filter 5, where smaller particles are removed to improve air cleanliness. Finally, the air passes through the high-efficiency air filter 6, where almost all particles are removed. Even minute particles are thoroughly filtered to ensure that the air entering the workshop meets extremely high cleanliness standards. After this series of filtration steps, the clean air is drawn into the blower 7 through the intake pipe 8, and then sent into the workshop body 1 through the air supply pipe 9. Through this efficient air filtration and circulation mechanism, the Class 1000 cleanroom can effectively remove particulate matter from the air, significantly improving air quality. The design of this system not only optimizes the ventilation structure of the workshop, but also enhances its practicality, ensuring that the cleanroom can maintain a stable and clean environment during high-tech production processes, providing ideal air conditions for production activities, thereby guaranteeing product quality and safety.

[0029] Reference Figures 1-3 A humidity regulating component is installed on the upper part of the inner wall of the workshop body 1. The humidity regulating component includes a mounting plate 12, which is fixedly connected to the upper part of the inner wall of the workshop body 1. A humidity sensor 13 is fixedly connected to the lower middle part of the mounting plate 12. A water pump 16 is fixedly connected to the upper part of the mounting plate 12. A water pump pipe 17 is fixedly connected to the input end of the water pump 16. A water delivery pipe 18 is fixedly connected to the output end of the water pump 16. An atomizing nozzle 19 is fixedly connected to the end of the water delivery pipe 18 away from the water pump 16. The humidity sensor 13 is electrically connected to the water pump 16. The end of the water pump pipe 17 away from the water pump 16 is fixedly connected to the water storage tank 14.

[0030] In the air conditioning system of a Class 1000 cleanroom, the humidity sensor 13 plays a crucial sensing role. This sensor monitors the air humidity inside the cleanroom in real time and provides feedback based on preset humidity standards. When the detected humidity is lower than the set value, the system automatically controls the start of the water pump 16 to increase the ambient humidity. The start of the water pump 16 drives the water extraction pipe 17 to work, which is responsible for effectively drawing water from the water storage tank 14 to the water pump 16. Then, the water pump 16 delivers the extracted water to the atomizing nozzle 19 through the water delivery pipe 18. In the atomizing nozzle 19, the water is atomized... The system rapidly atomizes into fine water mist and releases it evenly into the air. This process not only effectively increases the humidity in the workshop but also improves air quality and ensures the stability of the workshop environment. Through this efficient ventilation structure, the system can flexibly adjust the air humidity inside the workshop, achieving precise control of the cleanroom environment. This greatly improves the functionality and adaptability of the ventilation system. This intelligent humidity control solution not only meets the strict environmental requirements of cleanrooms but also helps improve product quality and reliability during the production process, providing a solid environmental guarantee for high-tech production.

[0031] Working principle: When ventilation is required inside the workshop, the blower 7 is started, driving the intake pipe 8. Air from inside the filter box 2 is drawn into the blower 7 through the intake pipe 8, creating a negative pressure inside the filter box 2. External air is then drawn into the filter box 2 through the intake pipe 3. Larger particles are filtered by the pre-filter 4, then smaller particles are removed by the medium-efficiency filter 5, and finally, even smaller particles are removed by the high-efficiency air filter 6. Finally, the air is drawn into the blower 7 through the intake pipe 8 and then supplied to the workshop body 1 through the air delivery pipe 9. This enables the Class 1000 cleanroom to fully filter particulate matter in the air, improving the practicality of the ventilation structure. When it is necessary to adjust the humidity inside the cleanroom, the water pump 16 is started, which drives the water pumping pipe 17 to operate. Water from the water storage tank 14 is pumped into the water pump 16 through the water pumping pipe 17, and then the water is delivered to the atomizing nozzle 19 through the water delivery pipe 18. Finally, the water is atomized and discharged into the air through the atomizing nozzle 19. This enables the Class 1000 cleanroom ventilation structure to adjust the humidity inside the cleanroom, improving the functionality of the ventilation structure.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
