Description

Technical Field

[0001] This utility model relates to the field of cleanroom air treatment technology, specifically a high-efficiency and energy-saving ventilation and filtration structure for cleanrooms. Background Technology

[0002] A cleanroom is a specially designed room that removes pollutants such as microparticles, harmful air, and bacteria from the air within a certain space, and controls the temperature, humidity, cleanliness, airflow speed and distribution, noise and vibration, lighting, and static electricity within a certain required range. It has extremely high requirements for air quality.

[0003] However, existing high-efficiency and energy-saving ventilation and filtration structures for cleanrooms still have certain problems:

[0004] The filters in the existing high-efficiency energy-saving ventilation and filtration structures of cleanrooms require maintenance after long-term use. Usually, the filters are fixed inside the filtration structure with multiple sets of bolts. During maintenance, staff need to remove the bolts one by one to take out the filters, which makes filter replacement difficult and maintenance inconvenient, affecting the normal operation of the cleanroom.

[0005] Therefore, we propose a high-efficiency and energy-saving ventilation and filtration structure for cleanrooms to address the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a high-efficiency and energy-saving ventilation and filtration structure for clean rooms, in order to solve the problem mentioned in the background art that after the optical fiber is inserted into the ceramic ferrule for adhesive curing, the ferrule is usually removed from the mold manually or with simple tools. This is not only inefficient, but also prone to ferrule loosening or delamination, which leads to poor ferrule curing effect and affects the ferrule quality of the optical fiber.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency and energy-saving ventilation and filtration structure for clean rooms, comprising an outer casing, a base frame, a sealed door, and a controller. An L-shaped base frame is welded to the bottom of the outer casing, and a sealed door is rotatably connected to the front end of the outer casing. The controller is mounted on the outer surface of the sealed door.

[0008] The outer casing is equipped with a fixing frame inside. Two sets of support rods are symmetrically installed on the inner side wall of the fixing frame. Two sets of slots are opened at the front and back of the support rods. A first screw hole is opened on the inner side of the slot. A fixing rod is attached to the upper end face of the support rod. A filter screen is provided on the inner side of the fixing rod. A locking block that matches the slot is fixed at the bottom of the fixing rod. A second screw hole that matches the first screw hole is opened on the outer surface of the locking block. A threaded pin is threaded through the middle of the first screw hole and the second screw hole.

[0009] By adopting the above technical solution, a slot and a first screw hole are provided on the support rod inside the fixed frame, and a locking block with a second screw hole is provided at the bottom of the fixed rod. The filter screen is fixed by using a threaded pin through the two screw holes. The filter screen is installed and removed more conveniently by using a locking and threaded connection, which is conducive to maintenance and ensures the normal operation of the clean room.

[0010] Preferably, the upper and lower ends of the fixing frame are provided with four sets of first sliding grooves, and the inner top and inner bottom of the outer box are fixed with four sets of slide rails, and the fixing frame forms a sliding structure between the first sliding grooves and the slide rails.

[0011] By adopting the above technical solution, the first sliding grooves at the upper and lower ends of the fixed frame are adapted to the slide rails fixed at the top and bottom of the outer box, so that the fixed frame can slide along the slide rails, which facilitates the overall movement of the fixed frame. When maintaining components such as the filter screen, the fixed frame can be slid out for easy operation, improving the convenience and efficiency of maintenance.

[0012] Preferably, a rack is fixed to the upper end face of the fixing frame, a second sliding groove corresponding to the rack is opened on the inner top of the outer box, a motor is bolted to the upper end of the outer box, a drive shaft is movably connected to the output end of the motor, and a gear that meshes with the rack is fixed to the outer surface of the drive shaft.

[0013] Using the above technical solution, the motor starts and drives the drive shaft to rotate, and the gear on the drive shaft rotates accordingly. Since the gear meshes with the rack on the upper end face of the fixed frame, it drives the fixed frame to move on the slide rail, realizing the automation of the fixed frame movement. No manual operation is required, the position of the fixed frame is precisely controlled, the convenience and efficiency of maintenance of the filter screen and other operations are improved, and the labor input is reduced.

[0014] Preferably, a protective cover is bolted to the upper end face of the outer casing, and the protective cover covers the outside of the motor and gears.

[0015] By adopting the above technical solution, the protective cover is installed on the upper surface of the outer casing with bolts, so that it completely covers the motor and gears, forming a closed protective space to prevent dust, debris and other objects from entering the motor and gears, avoid damage caused by impurities, extend service life, and reduce the impact of motor operating noise on the outside world.

[0016] Preferably, an air inlet pipe is connected to one side of the outer casing, and a flow guide is connected to one end of the air inlet pipe. The flow guide is funnel-shaped, and an air volume regulating valve is provided in the middle of the air inlet pipe. An air outlet pipe is connected to the other side of the outer casing, and an energy-saving fan is fixed to one side of the air outlet pipe.

[0017] Using the above technical solution, outside air enters the air inlet duct through the horn-shaped air guide hood, and after the air volume is regulated by the air volume regulating valve, it enters the outer casing. In the outer casing, filtration and other treatments are completed, and then the air is delivered out by an energy-saving fan on the side of the air outlet duct. The air guide hood expands the air intake range, the air volume is precisely controlled by the air volume regulating valve, and the energy-saving fan provides power to realize air circulation, ensuring the stable operation of the ventilation and filtration function of the clean room, while reducing energy consumption.

[0018] Preferably, an air inlet is provided on one side of the fixing frame and the air inlet is connected to an air inlet pipe, and an air outlet is provided on the other side of the fixing frame and the air outlet is connected to an air outlet pipe.

[0019] By adopting the above technical solution, the air in the air inlet duct flows into the fixed frame through the air inlet, and after being filtered in the fixed frame, it enters the air outlet duct through the air outlet. This clarifies the air flow path between the fixed frame and the air inlet and outlet ducts, ensuring the smooth flow of ventilation and filtration. It allows the air to pass through the filters and other devices in the fixed frame in an orderly manner, achieving efficient air purification and transportation, and maintaining the air quality of the clean room.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. Inside the outer casing, a threaded pin passes through the first and second threaded holes and is threaded to fix the fixing rod and the support rod, thereby fixing the inner filter screen. The filter screen can be fixed by the engagement of the clip and the slot and the threaded connection of the threaded pin. Compared with the traditional method of fixing the filter screen with multiple bolts, the installation and removal of the filter screen is simpler and faster. It reduces the tedious operation of disassembling bolts one by one during maintenance, improves maintenance efficiency, shortens maintenance time, and ensures the normal and stable operation of the ventilation and filtration structure of the clean room. This ensures that the air quality of the clean room meets the standards and meets the strict requirements of the clean room for air quality.

[0022] 2. After the motor starts, the drive shaft at its output end rotates, driving the gear fixed on the outer surface of the drive shaft and meshing with the rack to rotate. Through the meshing transmission of the gear and rack, precise movement control of the fixed frame is achieved, so that the fixed frame can be automatically slid by the cooperation of the mechanical structure. When it is necessary to maintain and repair the filter screen and other components on the fixed frame, the fixed frame can be driven by the motor to slide out along the slide rail, which is convenient for the staff to operate and improves maintenance efficiency.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Please see Figures 1-5 This utility model provides a technical solution: a high-efficiency and energy-saving ventilation and filtration structure for clean rooms, including an outer casing 1, a base frame 2, a sealing door 3, and a controller 4. An L-shaped base frame 2 is welded to the bottom of the outer casing 1, and a sealing door 3 is rotatably connected to the front end of the outer casing 1. The controller 4 is installed on the outer surface of the sealing door 3. A fixing frame 10 is provided inside the outer casing 1. Two sets of support rods 13 are symmetrically installed on the inner side wall of the fixing frame 10. Two sets of slots 14 are opened at the front and rear of the support rods 13. A first screw hole 15 is opened on the inner side of the slot 14. A fixing rod 16 is attached to the upper end face of the support rod 13. A filter screen 17 is provided on the inner side of the fixing rod 16. A locking block 18 that matches the slot 14 is fixed at the bottom of the fixing rod 16. A second screw hole 19 that matches the first screw hole 15 is opened on the outer surface of the locking block 18. A threaded pin 20 is threaded through and threadedly connected to the middle of the first screw hole 15 and the second screw hole 19.

[0031] The L-shaped base frame 2 welded to the bottom of the outer casing 1 supports the outer casing 1, ensuring its stable placement. The sealing door 3, rotatably connected to the front of the outer casing 1, can be opened and closed for maintenance and repair operations. The controller 4 mounted on the outer surface of the sealing door 3 allows operators to control the entire filter structure. Inside the outer casing 1, the fixing frame 10 supports components such as the filter screen 17. Two sets of support rods 13 are symmetrically installed on its inner wall. Two sets of slots 14 are opened at the front and rear, and the first screw hole 15 inside the slots 14, the locking block 18 that matches the bottom of the fixing rod 16 and the slot 14, and the second screw hole 19 on the outer surface of the locking block 18 that matches the first screw hole 15 work together to pass through the threaded pin 20. By threading the first screw hole 15 and the second screw hole 19, the fixing rod 16 and the support rod 13 are fixed, thereby fixing the inner filter screen 17. The filter screen 17 can be fixed by the engagement of the locking block 18 and the locking groove 14 and the threaded connection of the threaded pin 20. Compared with the traditional method of fixing the filter screen 17 with multiple sets of bolts, the installation and removal of the filter screen 17 is simpler and faster, reducing the tedious operation of disassembling the bolts one by one during maintenance, improving maintenance efficiency, shortening maintenance time, ensuring the normal and stable operation of the ventilation and filtration structure of the clean room, and thus ensuring that the air quality of the clean room meets the standards and meets the strict requirements of the clean room for air quality.

[0032] The fixed frame 10 has four sets of first sliding grooves 21 at its upper and lower ends. Four sets of slide rails 22 are fixed to the inner top and bottom of the outer casing 1, and the fixed frame 10 forms a sliding structure with the first sliding grooves 21 and slide rails 22. A rack 23 is fixed to the upper surface of the fixed frame 10. A second sliding groove 24 corresponding to the rack 23 is opened on the inner top of the outer casing 1. A motor 25 is bolted to the upper end of the outer casing 1. A drive shaft 26 is movably connected to the output end of the motor 25. A gear 27 meshing with the rack 23 is fixed to the outer surface of the drive shaft 26. A protective cover 28 is bolted to the upper surface of the outer casing 1, and the protective cover 28 covers the outside of the motor 25 and the gear 27.

[0033] The four sets of first sliding grooves 21 opened at the upper and lower ends of the fixed frame 10 cooperate with the four sets of sliding rails 22 fixed at the top and bottom of the inner casing 1, so that the fixed frame 10 can slide on the sliding rails 22, forming a flexible sliding structure. The rack 23 fixed at the upper end of the fixed frame 10 works in conjunction with the corresponding second sliding groove 24 opened at the top of the inner casing 1. After the motor 25 bolted to the upper end of the outer casing 1 is started, the drive shaft 26 at its output end rotates, driving the gear 27 fixed on the outer surface of the drive shaft 26 and meshing with the rack 23 to rotate. Through the meshing transmission of the gear 27 and the rack 23, the fixed frame 10 can be rotated. The precise movement control of the 0-type gear is achieved by a protective cover 28 bolted to the upper end of the outer casing 1, which covers the motor 25 and gear 27. This allows the fixed frame 10 to slide automatically using the mechanical structure. When maintenance is required on components such as the filter screen 17 on the fixed frame 10, the fixed frame 10 can be driven by the motor 25 to slide along the slide rail 22, facilitating operation and improving maintenance efficiency. At the same time, the protective cover 28 effectively prevents dust and debris from entering the motor 25 and gear 27, avoiding damage caused by impurities, extending the service life of the equipment, and reducing the noise of the equipment operation from interfering with the outside world.

[0034] An air inlet pipe 5 is connected to one side of the outer casing 1. A flow guide 6, which is funnel-shaped, is connected to one end of the air inlet pipe 5. An air volume regulating valve 7 is installed in the middle of the air inlet pipe 5. An air outlet pipe 8 is connected to the other side of the outer casing 1. An energy-saving fan 9 is fixed to one side of the air outlet pipe 8. An air inlet 11 is provided on one side of the fixing frame 10 and is connected to the air inlet pipe 5. An air outlet 12 is provided on the other side of the fixing frame 10 and is connected to the air outlet pipe 8.

[0035] The air inlet duct 5 on one side of the outer casing 1 is connected to the funnel-shaped air guide 6. An air volume regulating valve 7 is installed in the middle of the air inlet duct 5. An energy-saving fan 9 is fixed on one side of the air outlet duct 8 on the other side. At the same time, the air inlet 11 on one side of the mounting bracket 10 is connected to the air inlet duct 5, and the air outlet 12 on the other side is connected to the air outlet duct 8. The energy-saving fan 9 generates suction when it runs. Outside air enters the air inlet duct 5 after the funnel-shaped air guide 6 expands the air intake range. The air volume regulating valve 7 adjusts the air intake flow rate. After entering the air inlet duct 5, the air flows into the mounting bracket 10 through the air inlet 11 for filtration and other treatments. The treated air then enters the air outlet duct 8 through the air outlet 12 and is finally discharged by the energy-saving fan 9. This ensures orderly air circulation, stable operation of the cleanroom ventilation and filtration function, and maintenance of the air quality in the cleanroom.

[0036] Working Principle: For this type of high-efficiency and energy-saving ventilation and filtration structure in cleanrooms, the energy-saving fan 9 generates suction, and outside air enters the air inlet duct 5 after the air intake range is expanded by the horn-shaped air guide 6. The air volume regulating valve 7 regulates the air intake flow rate, and the air flows into the fixed frame 10 through the air inlet 11. The filter screen 17 fixedly installed in the fixed frame 10 filters and treats the air. The treated air enters the air outlet duct 8 from the air outlet 12 and is finally discharged by the energy-saving fan 9. When it is necessary to maintain the filter screen 17 and other components, the motor 25 at the upper end of the outer casing 1 is started. The motor 25 drives the drive shaft 26 to rotate, so that the gear 27 on the drive shaft 26 meshes with the rack 23 at the upper end of the fixed frame 10. The fixed frame 10 slides out along the slide rail 22 in the outer casing 1 through the first slide groove 21 at the upper and lower ends, which is convenient for operation. The protective cover 28 at the upper end of the outer casing 1 protects the motor 25 and gear 27 from dust and debris and reduces noise interference, thereby realizing the stable operation and efficient maintenance of the cleanroom ventilation and filtration function.

[0037] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0038] Although the present invention 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
