Description

Technical Field

[0001] The present application relates to the technical field of laboratory air quality control, and in particular to a high-precision laboratory air quality control system. Background Art

[0002] In high-precision laboratories (such as biosafety labs, cleanroom labs, and microelectronics labs), air quality control systems place extremely high demands on the cleanliness, temperature, humidity, and pollutant control of the experimental environment. Traditional laboratory ventilation systems typically utilize unidirectional or recirculating air systems. However, during long-term operation, filter replacement, maintenance, and system downtime for overhauls can allow unfiltered air from outside to enter the laboratory, disrupting the stability of the experimental environment. This is particularly serious for experiments requiring long periods of time and high cleanliness requirements (such as cell culture and nanomaterial preparation).

[0003] At present, laboratory ventilation systems have the following main problems: primary filters, medium-efficiency filters, and other air quality treatment devices (such as dynamic ion derivatization devices / ion oxygen odor treatment equipment, etc.) are generally installed in air ducts. When replacing primary filters and medium-efficiency filters, the system needs to be shut down and the air duct needs to be disassembled. This is not only cumbersome to operate, but may also introduce external pollutants due to the entry and exit of personnel. High-efficiency filters are usually installed on the top of the laboratory. Replacing high-efficiency filters often requires dismantling the top plate structure and manually carrying a ladder into the laboratory for operation. There is a risk of directly carrying viruses and bacteria into the laboratory. In addition, traditional systems need to be completely shut down when replacing filters or performing maintenance, resulting in interruption of airflow in the laboratory, fluctuations in temperature, humidity, and cleanliness, and may affect experimental results. Summary of the Invention

[0004] In order to improve the replacement efficiency of filters and control processing devices, reduce the time that the air duct is exposed to the outside air, reduce the intrusion of unfiltered air, and at the same time ensure the continuous operation of the system and ensure the long-term stability of the experimental environment, the present application provides a high-precision laboratory air quality control system.

[0005] This application provides a high-precision laboratory air quality control system that adopts the following technical solutions:

[0006] A high-precision laboratory air quality control system, comprising a laboratory box, wherein both sides of the laboratory box are separated by an upper air inlet duct and a lower air outlet duct, the upper air inlet duct and the lower air outlet duct on the same side are commonly connected to an air circulation unit, the top of the laboratory box is connected to a mounting frame, the mounting frame supports a plurality of high-efficiency filters and a plurality of top plates, the mounting frame, the high-efficiency filters, the top plate and the laboratory box jointly separate an air supply space, the upper air inlet duct is connected to the air supply space, a primary-efficiency filter, a medium-efficiency filter and an air quality comprehensive treatment device are sequentially arranged in the upper air inlet duct along its air supply direction, and a terminal odor comprehensive treatment device is installed in the lower air outlet duct;

[0007] The outer wall of the laboratory box is provided with a first mounting port, a second mounting port and two third mounting ports, the primary filter is inserted into the upper air inlet duct through the first mounting port, the medium efficiency filter is installed in the upper air inlet duct through the second mounting port, and the air quality comprehensive treatment device and the terminal odor comprehensive treatment device are each installed on the laboratory box through one of the third mounting ports;

[0008] The laboratory box is provided with a first closing component for closing the first installation port and a second closing component for closing the third installation port. The laboratory box is provided with a flip closing component, which is used to simultaneously control the opening of the second installation port, flip the medium efficiency filter so that its windward side faces the second installation port, and close the upper air inlet duct. A storage component and a transportation component are installed in the air supply space. The storage component is used to store the new high-efficiency filter, and the transportation component is used to grab the old high-efficiency filter to the storage component and install the new high-efficiency filter on the installation frame.

[0009] By adopting the above technical solution, the primary filter, the medium-efficiency filter, the comprehensive air quality control device and the terminal odor comprehensive control device can all be directly removed and pulled out from the outer wall of the laboratory box, and the first installation port, the second installation port and the third installation port can be promptly closed by the first closing component, the flip closing component and the second closing component, thereby shortening the contact time between the upper air inlet duct and the lower air outlet duct and the external air, reducing the intrusion of unfiltered air, and ensuring the continuous cleanliness and stability of the experimental environment. Moreover, there is no need to disassemble the upper air inlet duct and the lower air inlet duct, which is conducive to improving replacement efficiency.

[0010] When replacing the high-efficiency filter, the storage component and the transport component are used to automatically replace the high-efficiency filter, without the need for personnel to enter the laboratory to dismantle the top plate structure, which is conducive to improving the replacement efficiency and eliminating the risk of human-induced contaminants (such as dust and microorganisms) entering the laboratory box.

[0011] Moreover, when the primary filter, medium-efficiency filter, integrated air quality control device and terminal odor control device on one side are being replaced, the air circulation unit on that side needs to stop working, but the air circulation unit on the other side can continue to operate, avoiding complete system shutdown, ensuring continuous operation of the system, and ensuring the long-term stability of the experimental environment.

[0012] Optionally, the first closing component includes a first sealing plate and a first movable frame, the first sealing plate is slidably inserted in the side wall of the laboratory box, the inner wall of the first mounting port is provided with a first slot, and a spring is also installed in the side wall of the laboratory box, the spring is connected to the first sealing plate, the primary filter is installed in the first movable frame, one side of the first movable frame is adapted to the first mounting port, when the first movable frame is located in the upper air inlet duct, the first sealing plate abuts against the first movable frame, and when the first movable frame is pulled out of the laboratory box, the first sealing plate is inserted into the first slot.

[0013] By adopting the above technical solution, when the first movable frame and the primary filter are pulled out, the spring pushes the first sealing plate to be quickly inserted into the first slot, which greatly shortens the exposure time of the upper air inlet duct.

[0014] Optionally, the first closing plate is connected to a guide wheel when it is rotated toward one end of the first slot. When the first movable frame is pulled out of the laboratory box, the guide wheel is inserted into the first slot. A strip hole is provided on the side wall of the laboratory box. The first closing plate is connected to a push-pull column. The push-pull column extends out of the strip hole. The push-pull column is hinged with a buckle. A fixed column is installed on the side wall of the first closing plate. When the first movable frame is located in the upper air inlet duct, the guide wheel abuts against the first movable frame, and the buckle can be buckled on the fixed column.

[0015] By adopting the above technical solution, the design of the guide wheel can make it easier for the first sliding frame to be pulled out from the upper air inlet duct, and when inserting a new primary filter, the push-pull column can be manually pushed to reset the first sealing plate, and the buckle can be buckled on the fixed column to lock the position of the first sealing plate, making it convenient for one person to replace and install the primary filter.

[0016] Optionally, the flip closure assembly includes a second sealing plate, a third sealing plate and a second movable frame, the second sealing plate, the third sealing plate and the second movable frame are fixed to each other and hinged together on one side of the second mounting port, the second movable frame is located between the second sealing plate and the third sealing plate, the second sealing plate and the third sealing plate are perpendicular to the second movable frame, the second sealing plate, the third sealing plate and the second movable frame are provided with a sealing gasket at one end away from the hinge axis, the second movable frame and the second sealing plate are adapted to the upper air inlet duct, the third sealing plate is adapted to the second mounting port, the medium efficiency filter is installed in the second movable frame, and when the third sealing plate seals the second mounting port, the second movable frame is located in the upper air inlet duct.

[0017] By adopting the above technical solution, first, during normal use, the third sealing plate seals the second mounting port. When the medium-efficiency filter needs to be replaced, the third sealing plate is flipped out of the second mounting port. At the same time, the second movable frame is flipped to the second mounting port, and the second sealing plate blocks the upper air inlet to prevent external air from pouring in. The staff can directly take out the medium-efficiency filter from the second movable frame and replace it with a new one. The reason for flipping the second movable frame to 90° before taking out the medium-efficiency filter is that the filter cloth of the medium-efficiency filter is relatively long, and the width of the second movable frame is relatively small. Therefore, if the medium-efficiency filter is directly pulled out, the diameter of the second mounting port will be appropriately reduced. In this case, the filter cloth of the medium-efficiency filter will be stuck in the second mounting port during the extraction process, and it is not convenient to insert a new medium-efficiency filter. Therefore, it is designed to be flip-type to avoid friction and jamming between the filter cloth and the edge of the second mounting port, which is more convenient for the installation and removal of the medium-efficiency filter.

[0018] Optionally, a sealing cover is provided on the laboratory box, and the sealing cover covers the second sealing plate, the third sealing plate and the hinge shaft of the second movable frame.

[0019] By adopting the above technical solution, the sealing cover covers the hinge shaft, thereby reducing the situation where external air directly enters the upper air inlet duct through the gap of the hinge shaft.

[0020] Optionally, the second closing component includes a fourth closing plate, the horizontal wall of the fourth closing plate is hinged with a first rocker arm and a second rocker arm, the other ends of the first rocker arm and the second rocker arm are hinged in the third mounting opening, the first rocker arm and the second rocker arm are staggered up and down and parallel to each other, a third rocker arm is hinged on one side of the third mounting opening, the third rocker arm is hinged to the horizontal wall of the fourth closing plate, and when the fourth closing plate is in an open state, the fourth closing plate is arranged close to the inner wall of the laboratory box.

[0021] By adopting the above technical solution, when taking out the comprehensive air quality control device and the comprehensive terminal odor control device, the fourth sealing plate can be pulled. With the cooperation of the first rocker arm, the second rocker arm and the third rocker arm, the fourth sealing plate flips over and closes the third installation opening. The hinge points of the first rocker arm, the second rocker arm and the third rocker arm are all set on the inside of the third installation opening to avoid external air leakage points. In normal operation, the fourth sealing plate is completely stored in the upper air inlet duct and does not occupy external space.

[0022] Optionally, the transport component includes a first servo drive unit, the first servo drive unit is connected to a moving base, the moving base is equipped with a second servo drive unit, the moving base is equipped with a first lifting cylinder, the first lifting electric cylinder, the first electric cylinder is equipped with an electric clamp, the first servo drive unit is used to drive the moving base to move along the X-axis direction, and the second servo drive unit is used to drive the first lifting electric cylinder to move along the Y-axis direction.

[0023] By adopting the above technical solution, the first servo drive unit and the second servo drive unit cooperate to drive the first lifting electric cylinder and the electric clamp to move to the top of the high-efficiency filter that needs to be replaced, and then the first lifting electric cylinder drives the electric clamp to grab the high-efficiency filter. Then the first servo drive unit, the second servo drive unit, and the first lifting electric cylinder cooperate to drive the high-efficiency filter to the storage assembly for storage for subsequent unified retrieval, and then grab the new high-efficiency filter at the storage assembly and install it on the mounting frame.

[0024] Optionally, the storage assembly is arranged adjacent to the side wall of the laboratory box, and the storage assembly includes a third servo drive unit, and the third servo drive unit is connected to a second lifting cylinder. The second lifting cylinder and the third servo drive unit are provided with limiting plates on both sides, and a transverse cylinder is provided on the side opposite to each other of the two limiting plates, and the transverse cylinder is connected to a support plate, and the support plate can pass through the limiting plate, and the new high-efficiency filter stack is arranged between the two limiting plates and supported on the two support plates.

[0025] By adopting the above technical solution, when the old high-efficiency filter moves close to the limit plate, the third servo drive unit drives the second lifting cylinder to extend from between the two limit plates, and then the old high-efficiency filter is placed on the second lifting cylinder. The third servo drive unit drives the second lifting cylinder to move back between the two limit plates, and then the transverse cylinder is started to move the two support plates away from each other. At this time, the new high-efficiency filter falls and stacks with the old high-efficiency filter, and then the second lifting cylinder drives the stacked high-efficiency filters to rise synchronously, and the transverse cylinder drives the support plate to reset again, and the second lifting cylinder falls and resets, so that the high-efficiency filter is stacked and supported on the support plate again, and then the electric gripper grabs the high-efficiency filter at the top and installs it on the mounting frame.

[0026] Optionally, a volatile organic compound transmitter is installed on the top of the laboratory box, the upper air inlet duct is connected to the air supply space through an air supply pipe, the air supply pipe is installed with an ozone transmitter, a VOC / TVOC transmitter, an online dust particle counter and an online floating bacteria sampler are hung in the laboratory box, and a first differential pressure gauge and a second differential pressure gauge are also installed on the laboratory box. The first differential pressure gauge is used to detect the air pressure difference on both sides of the primary filter, and the second differential pressure gauge is used to detect the air pressure difference on both sides of the medium efficiency filter.

[0027] By adopting the above technical solution, when the volatile organic compound transmitter, VOC / TVOC transmitter, online particle counter, and online airborne bacteria sampler detect abnormal data, the air quality control device and the terminal odor control device are simultaneously activated in high gear until the relevant data returns to normal indicators. The air quality control device and the terminal odor control device continue to operate. When the ozone transmitter detects that the ozone concentration exceeds the standard, the air quality control device and the terminal odor control device are switched to low gear. If the relevant data of the air quality control device and the terminal odor control device remain normal in the low gear state, the air quality control device and the terminal odor control device are shut down. This solution establishes a hierarchical response system for full-parameter environmental monitoring. Through data fusion from multiple types of sensors, it achieves accurate identification of pollution types, intelligent control of control devices, and dynamic optimization of system energy efficiency. The first and second differential pressure gauges can promptly detect the need for replacement of the primary and secondary filters.

[0028] Optionally, the top of the laboratory box is provided with a first inspection port for replacing the volatile organic compound transmitter, a second inspection port for replacing the ozone transmitter, and a replacement port for taking out the old high-efficiency filter.

[0029] By adopting the above technical solution, the volatile organic compound transmitter, ozone transmitter and high-efficiency filter can be uniformly removed and replaced outside the laboratory box, without the need for manual entry into the laboratory box, avoiding the risk of human-induced contaminants (such as dust and microorganisms) entering the laboratory box.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. The primary filter, medium-efficiency filter, integrated air quality control device, and integrated terminal odor control device can all be directly removed and pulled out from the outer wall of the laboratory box. The first, second, and third installation ports can be promptly sealed using the first sealing component, flip sealing component, and second sealing component. This shortens the contact time between the upper air inlet and lower air outlet ducts and the outside air, reduces the intrusion of unfiltered air, and ensures the continued cleanliness and stability of the experimental environment. Furthermore, there is no need to disassemble the upper and lower air inlet ducts, which is conducive to improving replacement efficiency.

The volatile organic compound transmitter, ozone transmitter and HEPA filter can be taken out and replaced outside the laboratory box, eliminating the risk of human-induced contaminants (such as dust and microorganisms) entering the laboratory box.

[0033] 3. When the primary filter, medium-efficiency filter, integrated air quality control device and terminal odor control device on one side are being replaced, the air circulation unit on that side needs to stop working, but the air circulation unit on the other side can continue to operate, avoiding a complete system shutdown, ensuring continuous operation of the system, and ensuring the long-term stability of the experimental environment;

DETAILED DESCRIPTION

[0047] The following is combined with Figure 1-11 This application is described in further detail.

[0048] The embodiments of the present application disclose a high-precision laboratory air quality control system.

[0049] like Figure 1 、 Figure 2 and Figure 3 The high-precision laboratory air quality control system includes a laboratory box 1, and an upper air inlet duct 11 and a lower air outlet duct 12 are provided on both sides of the laboratory box 1. The upper air inlet duct 11 is located above the lower air outlet duct 12, and the upper air inlet duct 11 and the lower air outlet duct 12 on the same side are commonly connected to an air circulation unit 2. In the embodiment of the present application, the air circulation unit 2 includes two mounting boxes 21, and the two mounting boxes 21 are spliced with each other. The two groups of upper air inlet ducts 11 and lower air inlet ducts are each connected to an mounting box 21, and a circulating air duct is provided in the mounting box 21, and a fan 22 is built into the circulating air duct.

[0050] The top of the laboratory box 1 is connected to a mounting frame 31, which includes several frame beams. Adjacent frame beams are connected by connecting block bolts. The connecting block located in the middle of the laboratory box 1 is cross-shaped, the connecting block located at the edge of the laboratory box 1 is T-shaped, and the connecting block located at the corner of the laboratory box 1 is L-shaped. A supporting steel beam is bolted inside the laboratory box 1. The frame beams located at the edge of the laboratory, the T-shaped connecting blocks, and the L-shaped connecting blocks are all placed on the supporting steel beams. The mounting frame 31 supports several high-efficiency filters 32 and a top plate 33. The four adjacent frame beams enclose a rectangular space, and the four adjacent frames jointly support the high-efficiency filters 32 / top plate 33. In the embodiment of the present application, there are 12 filters in total and are installed in the middle of the mounting frame 31 in a 4x3 arrangement. The mounting frame 31, the high-efficiency filters 32, the top plate 33, and the laboratory box 1 are jointly separated by an air supply space 111. The air in the air supply space 111 can only be discharged into the laboratory box 1 through the high-efficiency filters 32.

[0051] like Figure 1 and Figure 4 The upper air inlet 11 is connected to the air supply space 111 through an air supply pipe 112. The air supply pipe 112 is installed in the middle of the upper air inlet 11. A primary filter 41, a medium-efficiency filter 42, and an air quality comprehensive treatment device 43 are sequentially arranged in the upper air inlet 11 along its air supply direction. A terminal odor comprehensive treatment device 44 is installed in the lower air outlet 12. In the embodiment of the present application, the air quality comprehensive treatment device 43 is a dynamic ion derivatization device, and the terminal odor comprehensive treatment device 44 is an ion oxygen odor treatment device. In the embodiment of the present application, the primary filter 41 is a plate filter that intercepts particles ≥5μm, the medium-efficiency filter 42 is a bag filter that captures particles 1-5μm, and the high-efficiency filter 32 is a box filter that removes particles ≥0.3μm (HEPA) or particles ≥0.1μm (ULPA).

[0052] like Figure 1 、 Figure 6 and Figure 7 Four volatile organic compound transmitters 45 are installed on the top of the laboratory box 1. The volatile organic compound transmitter 45 is installed at the center of the connecting block. An ozone transmitter 46 is installed on the air supply duct 112. The detection head of the ozone transmitter 46 extends into the air supply duct 112. The shell of the ozone transmitter 46 is installed on the outer wall of the air supply duct 112. A VOC / TVOC transmitter 47, an online dust particle counter 48 and an online airborne bacteria sampler 49 are hung on the inner wall of the laboratory box 1. The online dust particle counter 48 and the online airborne bacteria sampler 49 are arranged near the exhaust port of the lower air duct 12, 0.8-1.5 meters from the ground.

[0053] A first differential pressure gauge 410 and a second differential pressure gauge 411 are also installed on the laboratory box 1. The first differential pressure gauge 410 is used to detect the air pressure difference on both sides of the primary filter 41, and the second differential pressure gauge 411 is used to detect the air pressure difference on both sides of the secondary filter 42. The first differential pressure gauge 410 and the second differential pressure gauge 411 are both located at the top of the upper air inlet duct 11 and in the air supply space 111.

[0054] like Figure 1 、 Figure 2 and Figure 8 Both outer walls of the laboratory housing 1 are provided with a first mounting port 13, a second mounting port 14, and two third mounting ports 15. The primary filter 41 is inserted into the upper air inlet duct 11 through the first mounting port 13, the medium-efficiency filter 42 is installed in the upper air inlet duct 11 through the second mounting port 14, and the air quality comprehensive treatment device 43 and the terminal odor comprehensive treatment device 44 are each installed on the laboratory housing 1 through a third mounting port 15. The top of the laboratory housing 1 is provided with a first inspection port 16 for replacing the volatile organic compound transmitter 45, a second inspection port 17 for replacing the ozone transmitter 46, a replacement port 19 for removing the old high-efficiency filter 32, and a third inspection port 18 for replacing the first and second differential pressure gauges.

[0055] The laboratory box 1 is provided with a first closing component 5 for closing the first installation port 13 and a second closing component 6 for closing the third installation port 15. The laboratory box 1 is provided with a flip closing component 7. The flip closing component 7 is used to simultaneously control the opening of the second installation port 14, flip the medium efficiency filter 42 so that its windward side faces the second installation port 14, and close the upper air inlet duct 11. A storage component 8 and a transport component 9 are installed in the air supply space 111. The storage component 8 faces the replacement port 19, and the storage component 8 is used to store a new high-efficiency filter 32. The transport component 9 is used to grab the old high-efficiency filter 32 to the storage component 8 and install the new high-efficiency filter 32 on the mounting frame 31.

[0056] After the air is discharged into the upper air inlet duct 11 in sequence, it is filtered through the primary filter 41, the medium efficiency filter 42 and the high efficiency filter 32 in sequence and then discharged into the laboratory box 1. When the volatile organic compound transmitter 45, the VOC / TVOC transmitter 47, the online dust particle counter 48 and the online planktonic bacteria sampler 49 detect that there are abnormalities in relevant data, the air quality comprehensive treatment device 43 and the terminal odor comprehensive treatment device are started synchronously in strong gear until the relevant data recovers to the index, and the air quality comprehensive treatment device 43 and the terminal odor comprehensive treatment device are continuously operated. When the ozone transmitter 46 detects that the ozone concentration exceeds the standard, the air quality comprehensive treatment device 43 and the terminal odor comprehensive treatment device 44 are switched to weak gear. If the air quality comprehensive treatment device 43 and the terminal odor comprehensive treatment device 44 are in the weak gear state and the relevant data continue to be normal, the air quality comprehensive treatment device 43 and the terminal odor comprehensive treatment device 44 are shut down. The solution builds a full-parameter environmental monitoring hierarchical response system, which, through data fusion of multiple types of sensors, enables accurate identification of pollution types, intelligent regulation of treatment devices, and dynamic optimization of system energy efficiency.

[0057] The first differential pressure gauge 410 and the second differential pressure gauge 411 can promptly detect whether the primary filter 41 and the secondary filter 42 need to be replaced, and the automatic fault lights of the air quality comprehensive treatment device 43 and the terminal odor comprehensive treatment device 44 will automatically light up when they need to be replaced. The primary filter 41, the secondary filter 42, the air quality comprehensive treatment device 43 and the terminal odor comprehensive treatment device 44 can all be directly removed and pulled out from the outer wall of the laboratory box 1, and the first installation port 13, the second installation port 14 and the third installation port 15 can be promptly closed through the first sealing component 5, the flip sealing component 7 and the second sealing component 6, shortening the contact time between the upper air inlet 11 and the lower air outlet 12 and the external air, reducing the intrusion of unfiltered air, ensuring the continuous cleanliness and stability of the experimental environment, and there is no need to disassemble the upper air inlet 11 and the lower air inlet, which is conducive to improving replacement efficiency.

[0058] According to the wind speed detection of the anemometer in the laboratory box 1, or the calculation of the self-cleaning time of the laboratory box 1, if the air supply volume drops by more than 15%, or the self-cleaning time of the clean room is extended by more than 50%, this indicates that the high-efficiency filter 32 needs to be replaced. Combined with manual visual inspection or camera detection combined with a deep learning system, it is determined which high-efficiency filter 32 has obvious damage, cracks or perforations on the filter paper, cracking or degumming of the frame sealant, or severe discoloration or mildew on the filter material, and the high-efficiency filter 32 is replaced. When replacing the high-efficiency filter 32, the high-efficiency filter 32 is automatically replaced through the cooperation of the storage component 8 and the transport component 9, without the need for personnel to enter the laboratory to disassemble the top plate 33 structure, which is conducive to improving the replacement efficiency and eliminating the risk of human-carried pollutants (such as dust and microorganisms) entering the laboratory box 1.

[0059] Moreover, when the primary filter 41, the medium filter 42, the air quality comprehensive control device 43 and the terminal odor comprehensive control device 44 on one side are being replaced, the air circulation unit 2 on that side needs to stop working, but the air circulation unit 2 on the other side can continue to operate, avoiding a complete shutdown of the system, ensuring the continuous operation of the system, and ensuring the long-term stability of the experimental environment.

[0060] like Figure 4 、 Figure 5 and Figure 9 The first closing assembly 5 includes a first sealing plate 51 and a first movable frame 52. The first sealing plate 51 is slidably inserted into the side wall of the laboratory box 1. The inner wall of the first installation opening 13 is provided with a first slot 131. The first sealing plate 51 is rotatably connected to one end of the first slot 131 and is connected to two guide wheels 53. A spring 54 is also installed in the side wall of the laboratory box 1. The spring 54 is connected to the first sealing plate 51. The primary filter 41 is installed in the first movable frame 52. The first movable frame 52 is L-shaped, and one side of the first movable frame 52 is adapted to the first installation opening 13. A strip hole 110 is provided in the side wall of the laboratory box 1. The first sealing plate 51 is connected to a push-pull column 55. The push-pull column 55 extends out of the strip hole 110. The push-pull column 55 is hinged with a buckle 56. When the first movable frame 52 is located in the upper air inlet duct 11, the guide wheel 53 abuts against the first movable frame 52, and the buckle 56 can be buckled on the fixed column 57. When the first movable frame 52 is pulled out of the laboratory box 1 , the guide wheel 53 is inserted into the first slot 131 .

[0061] When the first movable frame 52 and the primary filter 41 are pulled out, the spring 54 pushes the guide wheel 53 to quickly insert into the first slot 131 , and the first sealing plate 51 closes the first installation opening 13 , greatly shortening the exposure time of the upper air inlet duct 11 .

[0062] like Figure 4 and Figure 10The flip closure assembly 7 includes a second sealing plate 71, a third sealing plate 72 and a second movable frame 73. The second sealing plate 71, the third sealing plate 72 and the second movable frame 73 are fixed to each other and hinged together on one side of the second mounting opening 14. The second movable frame 73 is located between the second sealing plate 71 and the third sealing plate 72. The second sealing plate 71 and the third sealing plate 72 are both perpendicular to the second movable frame 73. The thickness of the second sealing plate 71 is less than the thickness of the third sealing plate 72. The second sealing plate 71, the third sealing plate 72 and the second movable frame 73 are all provided with a sealing gasket 74 at one end away from the hinge axis. The second movable frame 73 and the second sealing plate 71 are adapted to the upper air inlet duct 11, and the third sealing plate 72 is adapted to the second mounting opening 14. The medium efficiency filter 42 is installed in the second movable frame 73. When the third sealing plate 72 seals the second mounting opening 14, the second movable frame 73 is located in the upper air inlet duct 11, and the second sealing plate 71 fits against the inner wall of the upper air inlet duct 11. A sealing cover 75 is provided on the laboratory box 1 , and the sealing cover 75 covers the hinge shafts of the second sealing plate 71 , the third sealing plate 72 and the second movable frame 73 .

[0063] During normal use, the third sealing plate 72 seals the second mounting port 14. When the medium efficiency filter 42 needs to be replaced, the third sealing plate 72 is flipped out of the second mounting port 14. At the same time, the second movable frame 73 is flipped to the second mounting port 14, and the second sealing plate 71 blocks the upper air inlet 11 to prevent external air from pouring in. The staff can directly remove the medium efficiency filter 42 from the second movable frame 73 and replace it with a new medium efficiency filter 42. The reason for flipping the second movable frame 73 to 90° before taking out the medium efficiency filter 42 is that the filter cloth of the medium efficiency filter 42 is relatively long, and the width of the second movable frame 73 is relatively small. Therefore, if the medium efficiency filter 42 is directly pulled out, the diameter of the second mounting port 14 will be appropriately reduced. In this case, the filter cloth of the medium efficiency filter 42 will be stuck in the second mounting port 14 during the extraction process, and it is not convenient to insert the new medium efficiency filter 42. Therefore, it is designed to be flip-type to avoid friction and jamming between the filter cloth and the edge of the second mounting port 14, making it more convenient to install and remove the medium efficiency filter 42.

[0064] like Figure 8The second closure assembly 6 includes a fourth sealing plate 61. A first swing arm 62 and a second swing arm 63 are hinged to one end of the top wall of the fourth sealing plate 61. The other ends of the first swing arm 62 and the second swing arm 63 are hinged to the middle of the top of the third mounting opening 15. The first swing arm 62 and the second swing arm 63 are staggered vertically and parallel to each other. The hinge point between the first swing arm 62 and the fourth sealing plate 61 is farther from the center of the laboratory box 1 than the hinge point between the second swing arm 63 and the fourth sealing plate 61. A third swing arm 64 is hinged to the inner top wall of the third mounting opening 15, and the third swing arm 64 is hinged to one side of the third mounting opening 15. The third swing arm 64 is hinged to the center of the top wall of the fourth sealing plate 61. When the fourth sealing plate 61 is in the open state, the fourth sealing plate 61 is positioned near the inner sidewall of the upper air inlet 11 / lower air inlet.

[0065] When taking out the air quality comprehensive control device 43 and the terminal odor comprehensive control device 44, the fourth sealing plate 61 can be pulled. With the cooperation of the first rocker arm 62, the second rocker arm 63 and the third rocker arm 64, the fourth sealing plate 61 flips over and closes the third installation port 15. The hinge points of the first rocker arm 62, the second rocker arm 63 and the third rocker arm 64 are all set on the inner side of the third installation port 15 to avoid external air leakage points, and during normal operation, the fourth sealing plate 61 is completely received in the upper air inlet duct 11 without occupying external space.

[0066] like Figure 11 The transport assembly 9 includes a first servo drive unit 91, which includes two X-direction lead screws. The two X-direction lead screws are arranged near the side wall of the laboratory box 1. The two X-direction lead screws are rotatably connected to the laboratory box 1. The two X-direction lead screws are driven by a motor. The two X-direction lead screws are commonly threadedly connected to a moving seat 93. The moving seat 93 is equipped with a second servo drive unit 92. The second servo drive unit 92 includes a Y-direction lead screw. The Y-direction lead screw is rotatably connected to the moving seat 93. The Y-direction lead screw is driven by a motor. The Y-direction lead screw is threadedly connected to a first lifting cylinder. The first lifting cylinder is slidably connected to the bottom of the moving seat 93.

[0067] The first electric cylinder is equipped with an electric gripper 95 , which is a finger electric cylinder.

[0068] The first servo drive unit 91 and the second servo drive unit 92 cooperate to drive the first lifting cylinder 94 and the electric clamp 95 to move above the high-efficiency filter 32 that needs to be replaced, and then the first lifting cylinder 94 drives the electric clamp 95 to grab the high-efficiency filter 32. Then the first servo drive unit 91, the second servo drive unit 92, and the first lifting cylinder 94 cooperate to drive the high-efficiency filter 32 to move to the storage component 8 for storage for subsequent unified retrieval, and then grab the new high-efficiency filter 32 from the storage component 8 and install it on the mounting frame 31.

[0069] like Figure 11The storage assembly 8 is arranged near the side wall of the laboratory box 1, and the storage assembly 8 is located at one end of the X-direction screw. The storage assembly 8 includes a third servo drive unit 81, and the third servo drive unit 81 also includes a screw and a motor. The screw of the third servo drive unit 81 is arranged along the Y direction. The third servo drive unit 81 is connected to the second lifting cylinder 82. Limiting plates 83 are arranged on both sides of the third servo drive unit 81. A horizontal cylinder 84 is arranged on the side opposite to each other of the two limiting plates 83. The horizontal cylinder 84 is connected to a support plate 85, and the support plate 85 can pass through the limiting plate 83. The new high-efficiency filter 32 is stacked between the two limiting plates 83 and supported on the two support plates 85.

[0070] When the old HEPA filter 32 moves close to the limit plate 83, the third servo drive unit 81 drives the second lifting cylinder 82 to extend from between the two limit plates 83, and then the old HEPA filter 32 is placed on the second lifting cylinder 82. The third servo drive unit 81 drives the second lifting cylinder 82 to move back between the two limit plates 83, and then the transverse cylinder 84 is started to make the two support plates 85 move away from each other. At this time, the new HEPA filter 32 falls and stacks with the old HEPA filter 32, and then the second lifting cylinder 82 drives the stacked HEPA filter 32 to rise synchronously, and the transverse cylinder 84 drives the support plate 85 to reset again, and the second lifting cylinder 82 falls and resets, so that the HEPA filter 32 is stacked and supported on the support plate 85 again, and then the electric clamp 95 grabs the HEPA filter 32 at the top and installs it on the mounting frame 31.

[0071] The implementation principle of the embodiment of the present application is: the primary filter 41, the medium-efficiency filter 42, the comprehensive air quality control device 43 and the terminal odor comprehensive control device 44 can all be directly removed and pulled out from the outer wall of the laboratory box 1, and the first installation port 13, the second installation port 14 and the third installation port 15 are promptly closed through the first closing component 5, the flip closing component 7 and the second closing component 6, shortening the contact time between the upper air inlet duct 11 and the lower air outlet duct 12 and the external air, reducing the intrusion of unfiltered air, ensuring the continuous cleanliness and stability of the experimental environment, and there is no need to disassemble the upper air inlet duct 11 and the lower air inlet duct, which is conducive to improving replacement efficiency.

[0072] When replacing the high-efficiency filter 32, the high-efficiency filter 32 is automatically replaced through the cooperation of the storage component 8 and the transportation component 9, without the need for personnel to enter the laboratory to disassemble the top plate 33 structure, which is conducive to improving the replacement efficiency and eliminating the risk of human-induced contaminants (such as dust and microorganisms) entering the laboratory box 1.

[0073] Moreover, when the primary filter 41, the medium filter 42, the air quality comprehensive control device 43 and the terminal odor comprehensive control device 44 on one side are being replaced, the air circulation unit 2 on that side needs to stop working, but the air circulation unit 2 on the other side can continue to operate, avoiding a complete shutdown of the system, ensuring the continuous operation of the system, and ensuring the long-term stability of the experimental environment.

[0074] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
