Description

Technical Field

[0001] This utility model relates to the technical field of fresh air treatment systems, specifically an intelligent control clean fresh air treatment system for biological laboratories. Background Technology

[0002] In modern building environments, fresh air systems play a crucial role, especially in places like biological laboratories where stringent air quality requirements exist. Their main function is to introduce fresh outdoor air, purify it, regulate its temperature and humidity, and then deliver it indoors, while simultaneously expelling stale indoor air. This maintains the freshness and cleanliness of the indoor air, ensuring a stable experimental environment and accurate experimental results.

[0003] As a core component of a fresh air system to achieve air purification, the importance of the filter panel is self-evident. It can effectively intercept various pollutants in the air, such as dust, particulate matter, microorganisms, and harmful gases, ensuring that the air delivered indoors meets a high standard of cleanliness. In biological laboratories, the sensitivity and precision of experiments dictate strict requirements for air purity. Any minute contamination can interfere with the experimental process and thus affect the quality of the entire experimental environment.

[0004] However, in current practical applications, there are many problems that urgently need to be solved in the installation of filter panels. The common installation method is to slide the filter panel between the limiting plates. Although the above installation method seems simple, it often causes a series of problems in actual operation. On the one hand, the problem of poor sealing is particularly prominent, often manifested as air leakage at the frame. The reasons for this problem are multifaceted. If the construction personnel are not careful enough during the installation process and fail to ensure that the filter panel frame and the limiting plate are tightly fitted, gaps will be left. At the same time, poor quality, aging, or inaccurate installation of the sealing strips will not effectively prevent air leakage. The consequences of air leakage at the frame are very serious. Unfiltered outdoor air will take the opportunity to bypass the filter panel and directly mix with the purified airflow into the laboratory, greatly reducing the filtration effect of the fresh air system and making it difficult to meet the cleanliness of the indoor air to meet the experimental requirements. On the other hand, due to improper installation, the filter plate will be subjected to instantaneous wind pressure fluctuations when the system starts and stops. When the fresh air system starts, the fan runs rapidly, and the airflow and pressure change drastically in a short period of time. Under such impact, the unstable filter plate is prone to displacement or shaking. Similarly, at the moment the system stops running, the sudden disappearance of wind pressure will also cause the filter plate to shake due to inertia. Long-term exposure to the above unstable state will not only cause obvious abnormal noises in the filter plate, disturbing the quietness of the experimental environment, but will also accelerate its wear and damage, shortening its service life. More seriously, the displacement of the filter plate will further damage the already fragile sealing structure between it and the frame, making the air leakage problem more serious, forming a vicious cycle, seriously affecting the normal operation of the fresh air system, and threatening the air quality and experimental safety of the laboratory.

[0005] Therefore, we propose an intelligent control system for clean air treatment in biological laboratories to solve the above problems. Utility Model Content

[0006] (I) Technical problem to be solved: In view of the shortcomings of the existing technology, this utility model provides an intelligent control system for clean air treatment in biological laboratories to solve the problems mentioned in the background technology.

[0007] (II) Technical Solution: To achieve the above objectives, this utility model provides the following technical solution: an intelligent control biological laboratory clean air treatment system, including a system frame, an air inlet fixedly connected to the system frame, a working chamber opened inside the system frame, a filter plate installed inside the working chamber, and limiting groove plates symmetrically fixedly connected to the walls of the working chamber.

[0008] Preferably, the limiting groove plate has a first chamber, an external connecting pipe is fixedly connected through the first chamber, a cone is fixedly connected through the first chamber, and air inlets are equidistantly opened on the cone.

[0009] Preferably, a corrugated cavity strip is fixedly connected to one side of the limiting groove plate, and a sealing strip is fixedly connected to the end face of the corrugated cavity strip away from the limiting groove plate. Transfer holes are provided at equal intervals on both the limiting groove plate and the corrugated cavity strip.

[0010] Preferably, a second chamber is provided inside the corrugated cavity strip, and a pushing column is slidably connected to the second chamber laterally.

[0011] Preferably, a strain gauge is fixedly connected to the end of the pushing column away from the cone, and an auxiliary plate is fixedly connected to the second chamber.

[0012] Preferably, one end of the pushing column slides inside the cone.

[0013] Preferably, the limiting slots are arranged symmetrically, and two limiting slots form a limiting group.

[0014] (III) Beneficial Effects: Compared with the prior art, this utility model provides an intelligent control system for clean air treatment in biological laboratories, which has the following beneficial effects: 1. This utility model, through its overall design and adjustable limiting device, addresses the core issues of air leakage and air pressure fluctuations in the sliding and fitting installation of filter plates. Through structural innovation, it achieves dynamic optimization of the filter plate installation state. Its beneficial effects are mainly reflected in the following aspects: Dynamic sealing compensation eliminates installation gaps: The device can effectively compensate for assembly errors between the filter plate and the four limiting groove plates through the movable design of the sealing strip. Even if there is an initial gap during installation, the filter plate and the limiting groove plates can be tightly fitted by the auxiliary adjustment of the corrugated cavity strip. For biological laboratories, this can effectively ensure the purification rate of the air supplied to the room and avoid the risk of contamination of experimental samples, such as cell culture and gene sequencing samples, by microorganisms and particulate matter. Adapting to material deformation and maintaining long-term sealing performance: During long-term use, the filter plate will undergo slight deformation due to changes in temperature and humidity, such as thermal expansion and contraction of the frame. Traditional fixed limiting plates will create new gaps due to rigid contact. However, the adjustable device automatically adapts to deformation through an elastic adjustment structure, continuously maintaining sealing pressure, reducing the rate of sealing effect decay of the filter plate throughout its entire life cycle, and reducing system energy waste caused by air leakage.

[0015] 2. The design of the corrugated cavity strip in this utility model brings the following benefits to the overall operation: Breaking through model compatibility limitations and achieving wide-range compatibility: The continuous corrugated structure of the corrugated cavity strip can adapt to the size fluctuations of the filter plate through elastic deformation. The peaks of the corrugations will automatically shrink or expand according to the degree of compression, forming a tight wrap. Compared with traditional metal limiting groove plates, which can only be adapted to limiting plates of fixed size, it can cover multiple specifications of filter plates such as HEPA and ULPA commonly used in laboratories. There is no need to customize groove plates for different models, which greatly reduces spare parts inventory costs. Buffering instantaneous wind pressure impact and suppressing fluctuations and abnormal noises: The instantaneous wind pressure during system start-up and shutdown will push the filter plate. The hollow corrugated structure of the corrugated cavity strip can absorb energy in stages through the "deformation-rebound" process, thereby undergoing elastic deformation and absorbing impact energy. Furthermore, the aerodynamic damping generated by the second chamber inside the corrugated cavity strip buffers the remaining energy, thus preventing the filter plate from being directly stressed. Compared with the impact energy of traditional metal hard contact, which is entirely borne by the frame, it can effectively eliminate the metal impact sound caused by shaking, thereby eliminating high-frequency abnormal noises.

[0018] 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.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0020] Example: Please refer to Figures 1 to 6 As shown: A smart control system for clean air treatment in a biological laboratory includes a system frame 1, an air inlet 2 fixedly connected to the system frame 1, a working chamber 3 within the system frame 1, a filter plate 31 installed within the working chamber 3, and restrictive groove plates 4 symmetrically fixedly connected to the walls of the working chamber 3. A first chamber 5 is formed within the restrictive groove plates 4, and an external connecting pipe 6 is fixedly connected through the first chamber 5. A cone 8 is fixedly connected within the first chamber 5, and air inlets 9 are equidistantly spaced through the cone 8. The restrictive groove plates 4... A corrugated cavity strip 10 is fixedly connected to the side. A sealing strip 11 is fixedly connected to the end face of the corrugated cavity strip 10 away from the limiting groove plate 4. Transfer holes 7 are equally spaced on both the limiting groove plate 4 and the corrugated cavity strip 10. A second chamber 12 is opened inside the corrugated cavity strip 10. A pushing column 13 is laterally slidably connected to the second chamber 12. A strain gauge 14 is fixedly connected to the end of the pushing column 13 away from the cone 8. An auxiliary plate 15 is fixedly connected inside the second chamber 12. One end of the pushing column 13 slides inside the cone 8.

[0021] in: The limiting groove plates 4 are arranged symmetrically, and two limiting groove plates 4 form a limiting group. The filter plate 31 is limited by two limiting groups.

[0022] The external connecting pipe 6 is connected to an external air pump and is mainly used to pump air into the first chamber 5.

[0023] Gas can enter the cone 8, and as the gas is pumped in, it can push the push column 13 to move.

[0024] The first chamber 5 is connected to the second chamber 12 through the transfer hole 7.

[0025] The cone 8, the pushing column 13, the strain gauge 14, and the auxiliary plate 15 are set as a group, and there are multiple groups in total. Each strain gauge 14 in the group is electrically connected to the main controller. In use, the values ​​of multiple strain gauges 14 can be compared to determine whether there is a difference in the force on each part of the sealing strip 11, and thus determine the sealing status of the sealing strip 11 under this state.

[0026] Working principle: In use, the filter plate 31 is slidably set in the limiting group composed of the limiting groove plate 4, and then gas is pumped into the first chamber 5 through the external connecting pipe 6 by an external air pump. As the gas is pumped in, the gas will enter the second chamber 12 of the corrugated cavity strip 10 through the transfer hole 7. At this time, the corrugated cavity strip 10 will move closer to the filter plate 31 with the sealing strip 11. Furthermore, in the above process, as the corrugated cavity strip 10 expands, the pushing column 13 will move laterally in the cone 8 to guide and limit the stable movement of the corrugated cavity strip 10. Furthermore, during this process, the gas entering the first chamber 5 will enter the inner cavity of the cone 8 through the air inlet 9 opened on the cone 8 and push the pushing column 13 sliding inside the cone 8; as the corrugated cavity strip 10 extends, the filter plate 31 will eventually be restricted by the sealing strips 11 on both sides, at which time the corrugated cavity strip 10 will be used as an auxiliary airbag component. On the other hand, after the filter plate 31 is restricted by the sealing strip 11, the strain gauge 14 will be in working state under this restricted state. Furthermore, since the cone 8, the pushing column 13, the strain gauge 14, and the auxiliary plate 15 are known to be a group, and multiple groups are set up, each strain gauge 14 in the group is electrically connected to the main controller. During use, the values ​​of multiple groups of strain gauges 14 can be compared to determine whether there is a difference in the force on each part of the sealing strip 11, thereby determining the sealing state of the sealing strip 11 under this state. Therefore, after the filter plate 31 is installed and restricted, the values ​​of each strain gauge 14 fed back by the main controller can be compared to determine whether the current restricted and fixed state meets the process requirements, thus providing services for subsequent work.
