Description

Technical Field

[0001] This invention relates to the field of cleanroom air supply equipment technology, specifically a novel energy-saving air supply device 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 indoor temperature, cleanliness, indoor pressure, airflow speed and distribution, noise and vibration, lighting, and static electricity within a certain required range. In other words, regardless of changes in external air conditions, the room can maintain the originally set requirements for cleanliness, temperature, humidity, and pressure. To ensure the internal air environment of the cleanroom's supply and return air, it is necessary to use an air supply device to filter and purify the incoming air.

[0003] An existing application with application number CN202120742457.5 discloses an energy-saving cleanroom air supply device for facilitating stable air supply, comprising a filter connection port, a filter screen mounting groove fixedly formed on the front surface of the filter connection port, a spring mounting groove fixedly formed on the rear surface inside the filter screen mounting groove, an air filter screen movably installed inside the filter screen mounting groove, a limiting groove fixedly formed on the front surface of the air filter screen, an air volume regulating air supply port fixedly installed on the lower end face of the filter connection port, an regulating air duct fixedly formed on the lower end face of the air volume regulating air supply port, and regulating blade connecting shafts movably installed on both sides of the regulating air duct near the lower port edge.

[0004] The aforementioned existing air supply devices adopt a purely mechanical design. Their internal structure is stable and energy-saving.

[0015] Preferably, the swing arm is arranged in a fan shape, and the outer arc of the swing arm is provided with toothed corners at equal intervals.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] This invention incorporates an air settling purification device, allowing air to enter the water tank through the air inlet pipe and directly contact the water for settling. The combined action of the first and second fan blades within the air inlet assembly accelerates the air intake rate and enhances the air contact and settling effect. Simultaneously, the settled air undergoes preliminary filtration and purification through a filter screen. When in use, the filter screen can be cleaned using a cleaning component, ensuring its filtration effectiveness and reducing the likelihood of clogging. Furthermore, the air inlet assembly and the cleaning component can operate in tandem, ensuring simultaneous cleaning of the water tank interior and the filter screen, significantly improving the structural functionality.

[0018] The air intake assembly is designed so that when the rotating rod achieves the meshing transmission of the first bevel gear and the second bevel gear, it can satisfy the rotation of the first fan blade, thereby accelerating the air intake efficiency. At the same time, when the rotating rod rotates, it can also achieve the rotation of the second fan blade, which can quickly agitate the water and accelerate the contact and settling effect between water and air.

[0019] The ratchet and scraping mechanisms are designed so that when the drum rotates counterclockwise with the servo motor, its internal circumferential teeth engage with a stop plate on one side of the turntable, causing the turntable to rotate counterclockwise in sync. This, in turn, allows the connecting rod at the center of the turntable to rotate the bottom plate, which in turn engages with the transmission groove at the top of the moving frame, causing the brush plate at the outer end of the moving frame to reciprocate. This quickly cleans the bottom of the water tank, reducing dust accumulation and clogging, and accelerating wastewater discharge. When the drum rotates clockwise, its internal teeth intermittently push the stop plate, causing it to retract intermittently in conjunction with a spring plate on one side. This allows for simultaneous air intake without the scraping mechanism, enabling flexible switching between air intake and scraping cleaning modes depending on the situation.

[0020] The water-filling sealing assembly, during water filling of the tank, raises the air cushion as the water level rises. This air cushion, along with the outer tube, not only compresses the spring but also drives the side plates on both sides of the upper end. These side plates, in conjunction with the inclined grooves inside, facilitate the lateral relative pushing of the transmission rods, sleeves, elastic telescopic rods, and sealing blocks on both sides. When the sealing blocks on both sides come close together, they help to seal the water inlet of the inlet pipe, stopping the water filling process. This ensures that the water level inside the tank efficiently meets the requirements for air settling while preventing overflow.

[0021] The cleaning components are designed so that when the rotating rod rotates, it can also meet the meshing transmission of the third and fourth bevel gears. When the fourth bevel gear rotates, it can meet the synchronous rotation of the drive wheel and the gear plate. When the gear plate rotates, it can intermittently transmit power with the upper rack to meet the pre-movement of the rack. The swing arm connected to the outside of the gear plate can mesh with the tooth block set in the middle of the lower end of the connecting frame during rotation, thereby realizing the reset push of the connecting frame and the rack. Thus, the connecting frame can indirectly meet the reciprocating movement of the protective cover and the scraper inside the protective cover, so that the scraper can be linked to scrape and clean the outside of the filter screen, reduce dust clogging of the filter screen, and improve its initial filtration effect on the air.

[0022] The setup of the drive wheel, belt, driven wheel, third blade, and hose allows the drive wheel to rotate synchronously with the fourth bevel gear, working in conjunction with the belt's transmission. As the driven wheel rotates, the third blade, located to the left of the driven wheel, rotates simultaneously, generating a rotational suction force. This force draws dust scraped off by the scraper and falling into the lower part of the protective cover into the hose. The scraped dust particles are then discharged back into the lower part of the water tank through the hose and the exhaust port on the lower left side of the connecting shell. This process can be synchronized with the cleaning activities of the scraping mechanism, significantly improving cleaning efficiency. Attached Figure Description

[0046] The working principle is as follows:

[0047] When air supply activities are to be carried out inside the clean room, the main fan 5 installed inside the housing 1 is operated. The main fan 5, in conjunction with the motor 6 and the pulley group, rotates to draw in air. Then, outside air can enter the housing 1 and enter the exhaust duct 7 through the transmission of the main fan 5. After being transported by the exhaust duct 7, it enters the clean room. When the air enters the housing 1 and is discharged, it can pass through the first filter plate 3 and the second filter plate 8 respectively to assist in meeting the multiple filtration treatment of the air and ensure the cleanliness of the incoming air.

[0048] To further enhance the air purification effect, water can be injected into the water tank 91 through the water inlet pipe 9812. Through the transmission of the water through the water inlet pipe 9812, inner pipe 984, and outer pipe 982, the water can collect at the lower end of the water tank 91. Simultaneously, as the water level at the lower end of the water tank 91 rises, it pushes the air cushion 983 connected to the bottom of the outer pipe 982, causing the air cushion 983 to move automatically upwards using buoyancy. During the upward movement of the air cushion 983, the outer pipe 982 is simultaneously pushed upwards. As the outer pipe 982 moves upwards, the top-mounted spring 986 is compressed, and the side plates 987 on both sides of the upper end move upwards. The upward movement of the side plates 987, along with the inclined grooves inside the side plates 987, causes the air cushion to move upwards. The connecting transmission rods 988 will move laterally in conjunction with the limiting docking movement of the fixed plate 985. As a result, the two transmission rods 988 will simultaneously push the top connecting sleeves 989, causing the two sleeves 989 to move laterally relative to each other along the left and right sides of the water inlet pipe 9812. At the same time, as the two sleeves 989 move relative to each other, the elastic telescopic rods 9810 respectively set inside the two sleeves 989 will push the connecting sealing block 9811 on one side, causing the two sealing blocks 9811 to come closer together to block the water inlet of the water inlet pipe 9812. This keeps the water injected into the water tank 91 at a certain level, and avoids water overflow without affecting the air settling treatment, greatly improving the automation of water injection.

[0049] Subsequently, when drainage is required, the sewage can be discharged through the drain pipe located at the lower right side of the water tank 91. As the sewage is discharged, the water level continuously decreases, which will release the lifting effect of the air cushion 983. In this way, the spring 986, which is in a compressed state and is against the upper end of the outer tube 982, will rebound to assist the downward movement of the outer tube 982. Through the downward movement of the outer tube 982, the side plates 987 on both sides will drive the transmission rod 988 again, so that the transmission rods 988 on both sides can satisfy the lateral opposite movement of the sleeve 989, the elastic telescopic rod 9810 and the sealing block 9811, thereby releasing the blocking effect of the sealing blocks 9811 on the inlet of the water inlet pipe 9812, ensuring the automatic opening of the inlet, and greatly improving the convenience of water injection.

[0050] After the water tank 91 completes the water filling process, the servo motor 971 can be activated to rotate the bottom-connected rotating drum 9722 clockwise. As the drum 9722 rotates clockwise, the rotating rod 973 connected to its bottom will synchronize with the externally connected first bevel gear 974. Furthermore, the first bevel gear 974 can mesh with the upper-connected second bevel gear 975, causing the second bevel gear 975 to engage with the connected rod to drive the rotation of the first fan blade 976. The rotation of the first fan blade 976 accelerates the entry of air from the air intake shroud 93 into the air intake pipe. 92. Air enters the lower part of the water tank 91 through the air inlet pipe 92, so that the air comes into direct contact with the water to settle the dust particles inside the air, ensuring that the air undergoes efficient pretreatment. The settled air can be discharged through the through hole 9813 on the right side of the support plate 94. After passing through the combination of the exhaust hood 95 and the filter screen 96, the settled air is filtered and purified before being discharged, further enhancing its cleanliness. In addition, with the multiple filtration processes of the first filter plate 3 and the second filter plate 8, the cleanliness of the air can be significantly improved, ensuring that the air entering the clean room meets the standards.

[0051] Secondly, when the rotating rod 973 rotates, the second fan blade 977 connected to its bottom can rotate synchronously to agitate the water at the lower end of the water tank 91, causing it to tumble rapidly and enhancing the contact and settling effect with air. Furthermore, when the servo motor 971 rotates the rotating drum 9722 in the reverse direction, it can engage with multiple equidistant teeth arranged circumferentially inside the drum 9724 to contact the abutment block 9723 on one side of the turntable 9724. This ensures the synchronous rotation of the drum 9722 and the turntable 9724. Consequently, the connecting rod 9726 connected in the middle of the turntable 9724 will rotate simultaneously, achieving the circumferential rotation of the bottom-connected rotating plate 9781. The moving frame 9782, equipped with the transmission groove 9783, will move along the bottom of the water tank 91 through the circumferential rotation of the rotating plate 9781. The reciprocating linear movement, in conjunction with the guide rods 9784 connected to both sides at the upper end, enables stable reciprocating linear movement. Thus, the brush plate 9785 connected to the outside of the rotating plate 9781 can satisfy the brushing cleaning of the bottom of the water tank 91, reducing the problem of dust particle adhesion and accumulation. Through the reciprocating brushing effect, the efficiency of dust particle and impurity discharge is accelerated during the subsequent sewage discharge, avoiding the problem of dust particle accumulation affecting air settling efficiency. When the servo motor 971 drives the rotating drum 9722 clockwise, the circumferentially equidistant teeth inside it will squeeze the abutment block 9723. The abutment block 9723, in conjunction with the elastic support of the spring plate 9725 connected to one side, performs intermittent inward movement. In this way, the air intake mode and brushing cleaning mode can be flexibly switched according to different situations.

[0052] After the air has undergone initial filtration and purification via the exhaust hood 95 and filter 96, a cleaning component 99 is provided to allow for cleaning of the filter 96 without shutting down the machine. When the rotating rod 973 rotates, it simultaneously drives the rotation of the third bevel gear 991 connected to it, enabling the third bevel gear 991 to engage with the fourth bevel gear 992 on its lower right side. This causes the drive wheel 993, connected to the fourth bevel gear 992, to rotate synchronously. The gear disc 99111, connected to the drive wheel 993 via a shaft, rotates accordingly, engaging the rack 99112 connected to it at the top, allowing the rack 99112 to perform a pre-movement laterally. Simultaneously, the rotation of the gear disc 99111 also drives the synchronous rotation of the externally connected swing arm 99113. Because the gear disc 99111 is shaped like a semi-gear disc, it can only fulfill certain functions. The rack 99112 moves laterally to the left, while the rotating swing arm 99113 can mesh with the toothed block 99116 at the lower center of the connecting frame 99115 when the gear plate 99111 cannot meet the meshing transmission of the rack 99112. This allows the connecting frame 99115 to move laterally to the right and simultaneously allows the rack 99112 to move to the right and reset, so that it can re-mesh with the rotating gear plate 99111. Thus, the rack 99112 and the connecting frame 99115 can cooperate with the support and guidance of the limiting plate 99114 to realize the lateral reciprocating movement of the lower docking plate 99117 connected to the protective cover 999. In this way, the scraper 9910 located inside the protective cover 999 can assist in scraping and cleaning the dust attached to the filter surface of the filter screen 96, so that the filter screen 96 is in a highly efficient preliminary filtration and purification state, reducing the probability of clogging and improving the air pretreatment effect.

[0053] The dust particles that are scraped off can fall into the lower part of the protective cover 999. At this time, the fallen dust will drive the drive wheel 993 to rotate through the fourth bevel gear 992. When the drive wheel 993, in conjunction with the external phase transmission connecting belt 994, drives the driven wheel 995 to rotate synchronously, the dust will enter the hose 998 through the rotational suction of the third fan blade 996 connected to one side of the driven wheel 995. Then, it will enter the lower part of the docking shell 997 along the hose 998. Finally, it will be discharged into the lower part of the water tank 91 through the exhaust port on the left side of the lower part of the docking shell 997. The subsequent sewage discharge activity satisfies the need for rapid cleaning of the dust adhering to the outside of the filter screen 96.
