Description
Technical Field
[0001] The utility model relates to the field of FFU filters, in particular to a simple operating room air purification system. Background Art
[0002] FFU filter, or fan filter unit, is an air purification device commonly used in clean rooms and dust-free workshops. It integrates a fan, filter and static pressure box into one. It removes dust, microorganisms and other pollutants in the air through high-efficiency filters to ensure the cleanliness of the output air. It is widely used in electronics, semiconductors, biopharmaceuticals, clean rooms and other industries, and can effectively improve product quality and production efficiency.
[0003] Most of the existing widely used air filters are FFU filters, but in their actual application, the replacement cycle of the high-efficiency filter plates is 1-3 months, and the replacement is relatively frequent. In addition, they are installed on the ceiling of the operating room. When replacing the high-efficiency filter plates, the high-efficiency filter plates located at a high place are less convenient to replace. Some products use a lifting structure to lift the high-efficiency filter plates and the mounting frame until the high-efficiency filter plates are lowered to an appropriate height before replacement. The support for the high-efficiency filter plates is poor. Specifically, since the high-efficiency filter plates are in a hoisting state, when the bolts are removed, the external force can easily cause the high-efficiency filter plates to shake, making it inconvenient for operators to align the bolts for disassembly and installation, reducing the convenience of replacing the high-efficiency filter plates and reducing their functional practicality. Utility Model Content
[0004] Based on this, the purpose of the present invention is to provide a simple operating room air purification system to solve the technical problem that the existing fan filter is installed on the top plate and it is inconvenient to replace the high-efficiency filter plate.
[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a simplified operating room air purification system, comprising an operating room and a filter body, wherein a hoisting mechanism is provided at the lower interior of the filter body, the hoisting mechanism comprising a support frame, a high-efficiency filter plate is mounted at the bottom of the support frame, a first hoisting rope and a second hoisting rope are respectively provided on both sides of the top of the support frame, a first fixed pulley and a second fixed pulley are respectively mounted on both sides of the inner wall of the filter body, and a servo motor is mounted on one side of the filter body;
[0006] Side plates are provided on both sides of the bottom of the support frame, and empty slots are opened on the inner sides of the side plates, and support legs are rotatably provided on the inner sides of the empty slots through rotating shafts.
[0007] By adopting the above technical solution, the servo motor relaxes the tension on the first lifting rope and the second lifting rope. Under the guidance of the first fixed pulley and the second fixed pulley inside the filter body, the two lifting ropes gradually release their lengths, causing the support frame and the high-efficiency filter plate connected thereto to begin to slowly descend. When they descend to a height that is convenient for the staff to operate, the staff removes the fixing bolts through the mounting holes on the support frame, thereby easily removing the high-efficiency filter plate. Then, the staff aligns the new high-efficiency filter plate with the mounting holes and fixes it to the support frame.
[0008] Furthermore, the first hoisting rope passes around a first fixed pulley, and the second hoisting rope passes around a second fixed pulley.
[0009] By adopting the above technical solution, it is ensured that when the servo motor reels and releases the lifting rope through the winding roller, the first lifting rope and the second lifting rope can move smoothly along the predetermined path. The presence of the fixed pulley provides a stable support point for the lifting rope, preventing the lifting rope from deflecting or tangling during movement, thereby ensuring the stability and safety of the support frame and the high-efficiency filter plate during the lifting process.
[0010] Furthermore, a winding roller is installed at the output end of the servo motor, and the first lifting rope and the second lifting rope pass through the filter body through the through hole and are wound around the outside of the winding roller.
[0011] By adopting the above technical solution, the servo motor can directly drive the winding roller to rotate. When the servo motor is started, the power it outputs is converted into a winding or releasing force for the first lifting rope and the second lifting rope through the winding roller, thereby realizing the lifting and lowering control of the support frame and the high-efficiency filter plate. This direct drive method improves the response speed and control accuracy of the system, making the replacement operation of the high-efficiency filter plate more accurate and reliable.
[0012] Furthermore, the servo motor is electrically connected to an external power supply through a control center. A side plate is provided at the lower outer side of the filter body to provide a mounting support point for the operating room ceiling and the filter body.
[0013] By adopting the above technical solution, the control center can conveniently control the start and stop and speed of the servo motor, and then accurately control the lifting and lowering of the support frame and the high-efficiency filter plate. This electrical connection not only improves the controllability and automation of the system, but also makes the replacement operation of the high-efficiency filter plate more convenient and efficient.
[0014] Furthermore, an inclined surface is formed on the outer side of the top surface of the support frame to provide a guiding force for the support frame. A mounting plate is fixedly provided on the inner side of the support frame, and a plurality of mounting holes are opened on the mounting plate to provide bolt mounting points for the support frame and the high-efficiency filter plate.
[0015] By adopting the above technical solution, the inclined surface can provide an inward guiding force for the support frame during its lifting and lowering process, so that the support frame can be retracted into the interior of the filter body more stably, thereby improving its operation smoothness.
[0016] Furthermore, a maintenance stepping block and a filter plate are provided on the top of the filter body, and handles are provided on both sides, and a fan is installed on the inner side of the filter body.
[0017] By adopting the above technical solution, the maintenance stepping block provides a stable standing platform for the workers, making it convenient for them to inspect and maintain the filter body, thereby ensuring the safety of the operation process.
[0018] Furthermore, return air ports are provided on both sides of the inner wall of the operating room, the filter body is connected to the return air ports through an air duct, and an air damper is installed on the air duct.
[0019] By adopting the above technical solution, the return air outlet serves as a channel for air circulation, which can effectively inhale and filter the air in the operating room, thereby ensuring the cleanliness and circulation of the air in the operating room. At the same time, the filter body is connected to these return air outlets through the air duct, so that the filter body can directly filter the air inhaled from the return air outlet, thereby improving the filtration efficiency and air cleanliness.
[0020] In summary, the present invention has the following beneficial effects:
[0021] 1. The utility model uses a lifting mechanism and supporting legs, and a servo motor to release the control of the first lifting rope and the second lifting rope. Under the guidance of the first fixed pulley and the second fixed pulley in the filter body, the two lifting ropes are released smoothly, so that the support frame and the high-efficiency filter plate connected thereto begin to slowly descend. When they are lowered to a height that the staff can easily operate, the supporting legs are rotated by the rotating shaft, and the supporting legs are used to support the supporting frame, thereby providing stability for the operator to perform the removal process of the high-efficiency filter plate, reducing the shaking amplitude of the high-efficiency filter plate during the replacement process, and then performing the necessary replacement operation. This not only avoids the risk of high-altitude operation required in the traditional replacement method, but also greatly improves the convenience of replacing the high-efficiency filter plate, making the replacement operation safer and more efficient.
[0022] 2. The utility model provides a filter body, an air duct, and a return air outlet, so that the air inside the operating room is effectively absorbed through the provided return air outlet. These return air outlets are evenly distributed on both sides of the inner wall of the operating room, which can ensure that the air in every corner of the operating room can be fully inhaled. At the same time, through the connection of the air duct, the inhaled air is transported to the filter body. Inside the filter body, the high-efficiency filter plate plays a key filtering role. When the air flows through the high-efficiency filter plate, the particles, bacteria and other harmful substances therein are effectively blocked and filtered out, thereby ensuring the cleanliness of the air. Subsequently, the filtered air is discharged back into the interior of the operating room, which not only ensures the continuous circulation and renewal of the air inside the operating room, but also effectively removes harmful substances in the air, providing the operating room with a clean and safe working environment. This air filtration and circulation system is of great significance to ensuring the success of the operation and the health of the patient. BRIEF DESCRIPTION OF THE DRAWINGS

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be a connection between the internal parts of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0034] The following describes an embodiment of the present invention based on its overall structure.
[0035] Example 1:
[0036] A simple operating room air purification system, such as Figure 1-Figure 7As shown, it includes an operating room and a filter body 1. A lifting mechanism 5 is provided at the lower part of the interior of the filter body 1. The lifting mechanism 5 includes a support frame 501. A high-efficiency filter plate 7 is installed at the bottom of the support frame 501. A first lifting rope 503 and a second lifting rope 504 are respectively provided on both sides of the top of the support frame 501. A first fixed pulley 505 and a second fixed pulley 506 are respectively installed on both sides of the inner wall of the filter body 1. A servo motor 507 is installed on one side of the filter body 1. The servo motor 507 relaxes the tension on the first lifting rope 503 and the second lifting rope 504. The two lifting ropes are pulled by the first fixed pulley 505 and the second fixed pulley 506 inside the filter body 1. 05 and the second fixed pulley 506, the length is gradually released, so that the support frame 501 and the high-efficiency filter plate 7 connected thereto begin to slowly descend. When they descend to a height that the staff can operate conveniently, the staff removes the fixing bolts through the mounting holes 802 on the support frame 501, thereby easily removing the high-efficiency filter plate 7. Then, the staff aligns the new high-efficiency filter plate 7 with the mounting holes 802 and fixes it to the support frame 501. This replacement method not only avoids the risk of high-altitude operations required in the traditional replacement process, but also significantly improves the replacement efficiency and convenience of the high-efficiency filter plate 7, making the entire replacement process safer and faster.
[0037] See Figure 3 、 Figure 4 The first lifting rope 503 passes around the first fixed pulley 505, and the second lifting rope 504 passes around the second fixed pulley 506, ensuring that when the servo motor 507 reels and releases the lifting rope through the winding roller 508, the first lifting rope 503 and the second lifting rope 504 can move smoothly along the predetermined path. The existence of the fixed pulley provides a stable support point for the lifting rope, preventing the lifting rope from deviating or getting knotted during the movement, thereby ensuring the stability and safety of the support frame 501 and the high-efficiency filter plate 7 during the lifting process. At the same time, the limiting effect of the first fixed pulley 505 and the second fixed pulley 506 enables the first lifting rope 503 and the second lifting rope 504 to control the support frame 501 and the high-efficiency filter plate 7 to descend at an appropriate speed when released, avoiding the rapid fall caused by the sudden relaxation of the lifting rope, and further protecting the safety of the staff.
[0038] See Figure 2 、 Figure 4The output end of the servo motor 507 is equipped with a winding roller 508. The first lifting rope 503 and the second lifting rope 504 pass through the filter body 1 through the through hole and are wound around the outside of the winding roller 508, so that the servo motor 507 can directly drive the winding roller 508 to rotate. When the servo motor 507 is started, the power output by it is converted into a winding or releasing force for the first lifting rope 503 and the second lifting rope 504 through the winding roller 508, thereby realizing the lifting and lowering control of the support frame 501 and the high-efficiency filter plate 7. This direct drive method improves the response speed and control accuracy of the system, making the replacement operation of the high-efficiency filter plate 7 more accurate and reliable. At the same time, the first lifting rope 503 and the second lifting rope 504 pass through the filter body 1 through the through hole and are wound around the outside of the winding roller 508, so that the lifting rope can maintain a stable tension when winding and releasing, avoiding the shaking or displacement of the support frame 501 and the high-efficiency filter plate 7 caused by the loosening of the lifting rope.
[0039] See Figure 2 、 Figure 4 The servo motor 507 is electrically connected to the external power supply through the control center. A side plate 12 is provided at the lower outer side of the filter body 1 to provide an installation support point for the operating room ceiling and the filter body 1. The control center conveniently controls the start and stop and speed of the servo motor 507, and then accurately controls the lifting and lowering actions of the support frame 501 and the high-efficiency filter plate 7. This electrical connection not only improves the controllability and automation of the system, but also makes the replacement operation of the high-efficiency filter plate 7 more convenient and efficient. At the same time, the side plate 12 serves as the installation support point between the operating room ceiling and the filter body 1, providing stable support and fixation for the filter body 1, ensuring the stability of the filter body 1 in the operating room, and preventing shaking or displacement caused by external force.
[0040] See Figure 2 、 Figure 3 、 Figure 6 , an inclined surface 502 is formed on the outer side of the top surface of the support frame 501, which is used to provide a guiding force for the support frame 501, and a mounting plate 801 is fixedly provided on the inner side of the support frame 501, and a plurality of mounting holes 802 are opened on the mounting plate 801, which are used to provide bolt mounting points for the support frame 501 and the high-efficiency filter plate 7, so that during the lifting process of the support frame 501, the inclined surface 502 can provide it with an inward guiding force, so that the support frame 501 can be more stably retracted into the interior of the filter body 1, thereby improving its operation smoothness. At the same time, these mounting holes 802 provide fixed points for the bolt connection between the support frame 501 and the high-efficiency filter plate 7, and are tightened by passing the bolts through the mounting holes 802, which can ensure the stability of the high-efficiency filter plate 7 on the support frame 501 and prevent it from loosening or falling off during use.
[0041] See Figure 2 、 Figure 3 The top of the filter body 1 is provided with an inspection stepping block 2 and a filter plate 3, and handles 4 are provided on both sides. A fan 6 is installed on the inside of the filter body 1. The inspection stepping block 2 provides a stable standing platform for the staff, which is convenient for them to inspect and maintain the filter body 1, ensuring the safety of the operation process. At the same time, the filter plate 3, as an important part of the filtration system, can effectively block and filter out impurities and particulate matter in the air, ensuring the cleanliness of the indoor air. At the same time, these handles 4 not only provide convenience for the staff when moving or installing the filter body 1, but also make the operation process more labor-saving and efficient.
[0042] Example 2:
[0043] See Figure 1 , return air vents 10 are provided on both sides of the inner wall of the operating room. The filter body 1 is connected with the return air vents 10 through the air duct 9. A damper 11 is installed on the air duct 9. The return air vents 10 serve as channels for air circulation and can effectively suck in and filter the air in the operating room, thereby ensuring the cleanliness and circulation of the air in the operating room. At the same time, the filter body 1 is connected with these return air vents 10 through the air duct 9, so that the filter body 1 can directly filter the air sucked in from the return air vents 10, thereby improving the filtration efficiency and the cleanliness of the air. At the same time, a damper 11 is also installed on the air duct 9. The existence of the damper 11 can control the opening and closing of the air duct 9, thereby adjusting the air flow and flow rate. When the air circulation volume needs to be increased, the damper 11 can be opened; when the air circulation volume needs to be reduced or maintenance is required, the damper 11 can be closed.
[0044] The implementation principle of the present utility model is as follows: when the high-efficiency filter plate 7 needs to be replaced, first, the servo motor 507 is controlled by the control center to be electrically connected to the external power supply, and the servo motor 507 drives the winding roller 508 to rotate, and at the same time, the first lifting rope 503 and the second lifting rope 504 are loosened. At this time, the first lifting rope 503 and the second lifting rope 504 are limited by the first fixed pulley 505 and the second fixed pulley 506, causing the support frame 501 and the high-efficiency filter plate 7 to gradually move downward until they are lowered to the operating height of the staff, and the support legs 14 are rotated by the rotating shaft 15, and the support frame 501 is supported by the support legs 14. The support is provided to provide stability for the operator to remove the high-efficiency filter plate 7, and then the bolts are removed through the mounting holes 802 to complete the removal operation of the high-efficiency filter plate 7 and the new high-efficiency filter plate 7 is installed. Subsequently, the support legs 14 are rotated and stored into the empty slots on the inner side of the side plate 13 through the rotating shaft 15. After that, the servo motor 507 drives the winding roller 508 to wind up the first lifting rope 503 and the second lifting rope 504, thereby realizing the lifting operation of the support frame 501 and the high-efficiency filter plate 7, until the support frame 501 and the high-efficiency filter plate 7 are retracted into the interior of the filter body 1, and the replacement operation of the high-efficiency filter plate 7 is completed;
[0045] The air inside the operating room is absorbed into the filter body 1 through the return air port 10 and the air duct 9. At the same time, the high-efficiency filter plate 7 inside the filter body 1 filters the air and then discharges the filtered air into the interior of the operating room to ensure the air quality inside the operating room.
