Description

Technical Field

[0002] A clean room, also known as a purified space, is a space within a specific range that circulates air to expel pollutants such as particulate matter, harmful air, and bacteria from the air, and controls the indoor temperature, cleanliness, pressure, airflow velocity and distribution, noise, vibration, lighting, and static electricity within a specific range. A clean room is a space where fresh air is delivered to the room through an air supply system and the air in the clean room is discharged through an exhaust system. In order to prevent external pollutants from flowing into the clean room, the clean room is usually maintained in a positive pressure state.

[0003] For example, the patent with the national authorized patent announcement number CN118089152B discloses a ventilation device with a purification structure for a clean room, including: a filter box and a first air inlet pipe, the first air inlet pipe is arranged on the right side of the filter box, and the inner cavity of the first air inlet pipe is connected to the inner cavity of the filter box; the second air inlet pipe is arranged on the left side of the filter box, and the inner cavity of the second air inlet pipe is connected to the inner cavity of the filter box; the number of filters is several, and the several filters are equidistantly arranged in the inner cavity of the filter box in the left and right directions. In this device, when the filter is seriously blocked or gas leaks at the pipe connection, an alarm can be issued in time to remind the staff to perform maintenance and repair, thereby preventing the formation of negative pressure in the clean room, avoiding external pollutants from flowing into the clean room, and preventing the temperature, humidity, static electricity, dust and other factors in the clean room from being uncontrollable, increasing the stability and consistency of the production process, and enhancing product quality.

[0004] However, the above-mentioned clean room ventilation device with a purification structure is not easy to disassemble and assemble the filter element, so each replacement or cleaning of the filter element requires more time and manpower, and at the same time, the exhaust wind direction cannot be regulated, which will lead to uneven air flow in local areas of the clean room. In some high-precision electronic component production areas, stable and uniform laminar air is required to prevent the deposition of dust and pollutants. The lack of wind direction control will destroy this ideal air flow pattern, and also limit the flexibility and scalability of the clean room, which is not conducive to the long-term development of the enterprise.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. Through the design of the installation box, guide port, air supply pipe, sewage air supply mechanism, guide mechanism and filter mechanism, when supplying and exhausting air in the clean room, the guide port and air supply pipe on both sides of the installation box can be installed outdoors and indoors respectively, and then the sewage air supply mechanism can be started to draw air from the clean room and the outside respectively and discharge the air into the air supply pipe through the exhaust port. The air supply pipe is provided with a filter mechanism, so that the air entering the air supply pipe needs to be discharged into the guide mechanism through the filter mechanism, so that both the air circulating in the clean room and the air introduced from the outside are filtered before entering the clean room or circulating again, which can effectively remove pollutants such as dust and microorganisms in the air, maintain the high cleanliness requirements in the clean room, and ensure production Or experiments and other activities are carried out in a stable air quality environment, and the guide mechanism can discharge filtered air into the clean room and discharge the air in the clean room to the outside, so as to realize the circulation of fresh air, and the sewage air supply mechanism treats the air inside and outside the clean room separately, avoiding cross contamination of the air inside and outside the clean room, which is helpful to maintain the cleanliness of the clean room, and in the process of discharging air through the guide mechanism, the guide mechanism can be extended and contracted, so that the staff can guide the air to the corresponding installation points according to the needs, so that in the clean room with complex layout, it can accurately control the flow direction and discharge position of the air according to the equipment layout, work flow, etc. in different areas, so as to avoid the impact of air turbulence on the clean room environment.

[0018] 2. Through the design of the casing, impeller, gear, motor and transmission belt, the guide ports and air supply pipes on both sides of the installation box are installed outdoors and indoors respectively, and the motor can be started, and the motor can drive the first transmission disc fixedly installed on the outer surface of the output shaft to rotate, and then the transmission belt set on the outer surface of the first transmission disc can drive the second transmission disc to rotate, and the second transmission disc is installed at one end of the gear, so that the gear can be driven to rotate and mesh with another set of gears to rotate relatively, and then the two sets of gears can drive the two sets of impellers to rotate relatively in the two sets of relatively arranged casings, and the rotation of the impellers in the casing can generate negative pressure, thereby The two sets of casings can use the guide ports to draw the air inside and outside the clean room into the casings through the air intake ports and discharge it from the air supply pipes connected thereto, thereby discharging outdoor air into the clean room and discharging indoor air back into the room, thereby maintaining the freshness of the air in the clean room, constantly renewing the indoor air, removing odors, moisture and pollutants generated indoors, and providing good air quality assurance for the production or working environment in the clean room.

[0019] 3.

The air filter element is in the shape of a cone, so that the air passing through the air filter element can filter dust and impurities in the air and retain them in the conical cylinder groove of the air filter element. When the air filter element needs to be replaced, the butterfly bolt in the docking plate at one end of the outer surface of the covering cylinder can be unscrewed to release the pressure of the butterfly bolt on the covering cylinder, so that the staff can push the covering cylinder to rotate between the connecting plates through the rotating plate, so that the covering cylinder can be flipped and unfolded from one end of the air supply pipe to display the air filter element in the air supply pipe to the outside, and then the staff can hold the outer surface of the handle and twist it clockwise, so that the handle can drive the limiting block on the outer surface of the air filter element to rotate in the limiting groove of the convex ring until it rotates to the limit The end of the positioning groove can make the limit block flush with the insertion port, so that the staff can pull the handle to drive the limit block on the outer surface of the air filter element to be pulled out from the insertion port, thereby realizing the removal of the air filter element. During installation, it is only necessary to insert the limit block on the outer surface of the air filter element into the insertion port and twist it counterclockwise, thereby realizing the locking of the air filter element in the convex ring, thereby realizing the connection between the connecting pipe and the air filter element, so that when removing the air filter element, the limit block can be pulled out from the insertion port through the twisting of the handle and the rotation of the limit block in the limit groove to complete the removal. The reverse operation can be performed during installation. The whole process does not require complicated tools or professional skills, reduces the difficulty of maintenance, and reduces maintenance time. In addition, due to the simple removal and replacement operation, the maintenance of the air filter element can be completed quickly, thereby reducing the time that the entire air supply and filtration system is stopped due to filter element maintenance, and can minimize the impact on production or other activities.

The high cleanliness requirement is met to ensure that production or experimental activities are carried out in a stable air quality environment, and the guide mechanism 3 can discharge the filtered air into the clean room and discharge the air in the clean room to the outside, so as to realize the circulation of fresh air, and the sewage air supply mechanism 2 treats the air inside and outside the clean room separately, avoiding the cross contamination of the air inside and outside the clean room, which is helpful to maintain the cleanliness of the clean room, and in the process of discharging air through the guide mechanism 3, the guide mechanism 3 can be extended and contracted, so that the staff can guide the air to be discharged to the corresponding installation point according to the needs, so that in the clean room with complex layout, it can be accurately controlled according to the equipment layout, work flow, etc. of different areas, so as to avoid the impact of air turbulence on the clean room environment.

[0036] like Figure 5-Figure 6 As shown, the sewage exhaust and air supply mechanism 2 includes two sets of casings 201, and the two sets of casings 201 are fixedly installed in the installation box 1 and are arranged opposite to each other. Impellers 203 are rotatably installed in the two sets of casings 201. The rotating rods of the two sets of impellers 203 pass through the casings 201, and the outer surfaces of the rotating rod segments passing through the outside of the casings 201 are fixedly installed with gears 204, and the two sets of gears 204 are meshed with each other.

[0037] The air intake and exhaust ports of the two sets of housings 201 are connected to the guide port 102 and the air supply pipe 103 respectively.

[0038] A mounting plate 202 is fixedly mounted on one end of the outer surface of one group of casings 201, a motor 205 is fixedly mounted on one end of the mounting plate 202, a first transmission disc 206 is fixedly mounted on the outer surface of the output shaft of the motor 205, a transmission belt 207 is sleeved on the outer surface of the first transmission disc 206, the other end of the transmission belt 207 is sleeved on the outer surface of the second transmission disc 208, and the second transmission disc 208 is fixedly mounted on one end of one group of gears 204, so that the second transmission disc 208 can be driven to rotate through the transmission belt 207 of the motor 205 to drive one group of gears 204 to rotate, and then this group of driven gears 204 can be meshed and driven to rotate relative to another group of gears 204, so that the two groups of impellers 203 can be driven to rotate relative to each other in the two groups of casings 201 arranged opposite to each other.

[0039] Through the design of the casing 201, the impeller 203, the gear 204, the motor 205 and the transmission belt 207, the guide port 102 and the air supply pipe 103 on both sides of the installation box 1 are installed outdoors and indoors respectively, and the motor 205 can be started, and the motor 205 can drive the first transmission disc 206 fixedly installed on the outer surface of the output shaft to rotate, so that the transmission belt 207 set on the outer surface of the first transmission disc 206 can drive the second transmission disc 208 to rotate, and the second transmission disc 208 is installed at one end of the gear 204, so that the gear 204 can be driven to rotate and mesh with another set of gears 204 to rotate relatively, so that the two sets of gears 204 can drive the two sets of impellers 203 to rotate relatively in the two sets of relatively arranged casings 201. The rotation of the impeller 203 in the casing 201 can generate negative pressure, so that the two sets of casings 201 can suck the air inside and outside the clean room into the casing 201 through the air intake port through the guide port 102 and discharge it from the air supply pipe 103 connected thereto, thereby achieving the discharge of outdoor air into the clean room and the discharge of indoor air into the room, thereby maintaining the freshness of the air in the clean room, constantly refreshing the indoor air, removing odors, moisture and pollutants generated indoors, and providing good air quality protection for the production or working environment in the clean room. In addition, this mechanism can handle the air flow inside and outside the clean room at the same time, realize two-way air circulation under the operation of the same equipment, and has a compact and efficient structure, reducing the space occupied and the cost of the equipment.

[0040] like Figure 7As shown, the flow guide mechanism 3 includes a rotating plate 302, which is rotatably installed between two groups of connecting plates 104, a covering cylinder 301 is fixedly installed at one end of the rotating plate 302, a docking plate 304 is fixedly installed at the other end of the outer surface of the covering cylinder 301, and a butterfly bolt 305 is installed on the inner thread of the docking plate 304, so that the covering cylinder 301 can be rotated in the connecting plate 104 through the docking plate 304 to cover one end of the air supply pipe 103, and is threadedly installed into the installation box 1 through the butterfly bolt 305, so that the covering cylinder 301 can touch one end of the air supply pipe 103 through the threaded top pressure of the butterfly bolt 305 and be connected with it.

[0041] One end of the covering tube 301 is connected to a universal telescopic air duct 303, so that the universal telescopic air duct 303 can freely expand and contract within a certain range through a plurality of telescopic segments, thereby exhausting the air to the corresponding installation point.

[0042] Through the design of the covering tube 301, the universal telescopic air duct 303, the docking plate 304 and the butterfly bolt 305, the air is discharged into the air supply pipe 103 and then discharged into the covering tube 301 again, and the other end of the covering tube 301 is connected to the universal telescopic air duct 303, so that the staff can use the extension and contraction of the universal telescopic air duct 303 to place it at the position where exhaust is needed, so that the exhaust demand will change with the changes in production process, equipment updates or layout adjustments, and the adjustability of the universal telescopic air duct 303 can adapt to these dynamic needs, whether it is the addition of new equipment that requires a new exhaust point, or the need to readjust the exhaust direction after the original equipment position changes, it can be easily operated, and due to the flexibility of the universal telescopic air duct 303, when planning the overall equipment layout of the clean room, the position of the equipment can be arranged more freely, which helps to improve the overall functionality and work efficiency of the clean room.

[0043] like Figure 8 As shown, the filtering mechanism 4 includes a connecting pipe 401 and an air filter element 405. The connecting pipe 401 is connected and installed in the air supply pipe 103. A convex ring 402 is connected and installed at one end of the connecting pipe 401. An insertion port 403 is provided at one end of the convex ring 402. A limiting groove 404 is provided on the inner ring wall of the convex ring 402. The insertion port 403 is connected to the limiting groove 404. A limiting block 407 of the air filter element 405 can be slidably inserted into the insertion port 403 of the convex ring 402, and the limiting block 407 can be driven to slide into the limiting groove 404 again by twisting the air filter element 405. The limiting block 407 is fixedly installed on the outer surface of the shell of the air filter element 405.

[0044] The air filter element 405 can be connected to the connecting pipe 401 and the air supply pipe 103 by being inserted into the convex ring 402, so that the air discharged from the air supply pipe 103 needs to pass through the air filter element 405 before being discharged from the universal telescopic air duct 303.

[0045] The air filter element 405 is in a conical cylindrical shape, so that the air passing through the air filter element 405 can filter dust and impurities in the air into the conical cylindrical groove of the air filter element 405.

[0046] A handle 406 is fixedly mounted on one end of the air filter element 405 .

[0047] Through the design of the connecting pipe 401, the convex ring 402, the insertion port 403, the limiting groove 404, the air filter element 405 and the limiting block 407, when the air is discharged into the air supply pipe 103, it will enter the air filter element 405 through the connecting pipe 401, and be filtered from the inside of the air filter element 405 to the outer surface and enter the covering cylinder 301 for discharge. The air filter element 405 is in a conical shape, so that the air passing through the air filter element 405 can filter the dust and impurities in the air and retain them in the conical cylinder groove of the air filter element 405. When the air filter element 405 needs to be replaced, it can be replaced by removing the covering cylinder 301. The butterfly bolt 305 in the docking plate 304 at one end of the outer surface of 301 is unscrewed to release the butterfly bolt 305 from the pressing fixation of the covering cylinder 301, so that the staff can push the covering cylinder 301 to rotate between the connecting plates 104 through the rotating plate 302, so that the covering cylinder 301 can be turned over and unfolded from one end of the air supply pipe 103 to display the air filter element 405 in the air supply pipe 103 to the outside, and then the staff can hold the outer surface of the handle 406 and twist it clockwise, so that the handle 406 can drive the limit block 407 on the outer surface of the air filter element 405 to move around the convex ring 402. The air filter element 405 is then removed from the air filter element 405 by pulling the handle 406 to pull the limit block 407 on the outer surface of the air filter element 405 out of the insertion port 403. During installation, the limit block 407 on the outer surface of the air filter element 405 only needs to be inserted into the insertion port 403 and twisted counterclockwise to lock the air filter element 405 in the convex ring 402, thereby achieving communication between the connecting pipe 401 and the air filter element 405. When removing the air filter element 405, the handle 406 is twisted and the limit block 407 is rotated in the limit groove 404, and finally the limit block 407 is pulled out from the insertion port 403 to complete the removal. The installation can be completed in reverse. The whole process does not require complicated tools or professional skills, which reduces the difficulty and time of maintenance. In addition, since the removal and replacement operation is simple, the maintenance of the air filter element 405 can be completed quickly, thereby reducing the time when the entire air supply and filtration system is stopped due to filter element maintenance, which can minimize the impact on production or other activities.

[0048] According to the above technical scheme, the working steps of this scheme are summarized and sorted out: when supplying and exhausting air in the clean room, the guide port 102 and the air supply pipe 103 on both sides of the installation box 1 can be installed outdoors and indoors respectively, and then the motor 205 can be started to drive the first transmission disc 206 fixedly installed on the outer surface of the output shaft to rotate, so that the transmission belt 207 set on the outer surface of the first transmission disc 206 can drive the second transmission disc 208 to rotate, and the second transmission disc 208 is installed at one end of the gear 204, so that the gear 204 can be driven to rotate and mesh with another set of gears 204 to rotate relatively together, so that the two sets of gears 204 can drive the two sets of impellers 203 to rotate relatively in the two sets of relatively arranged casings 201, and The rotation of the impeller 203 in the casing 201 can generate negative pressure, so that the two sets of casings 201 can suck the air inside and outside the clean room into the casing 201 through the air intake port through the guide port 102 and discharge it from the air supply pipe 103 connected thereto, thereby realizing the discharge of outdoor air into the clean room and the discharge of indoor air into the indoor room. When the air is discharged into the air supply pipe 103, it will enter the air filter element 405 through the connecting pipe 401, and be filtered from the inside of the air filter element 405 to the outer surface, enter the covering cylinder 301 and be discharged, so that both the air circulating in the clean room and the air introduced from the outside are filtered before entering the clean room or being circulated again, which can effectively remove pollutants such as dust and microorganisms in the air, and maintain the clean room. The high cleanliness requirement in the clean room is maintained, and the other end of the covering cylinder 301 is connected to the universal telescopic air duct 303, so that the staff can use the extension and contraction of the universal telescopic air duct 303 to place it at the position where exhaust is required. When the air filter element 405 needs to be replaced, the butterfly bolt 305 in the docking plate 304 at one end of the outer surface of the covering cylinder 301 can be unscrewed to release the pressure of the butterfly bolt 305 on the covering cylinder 301, so that the staff can push the covering cylinder 301 to rotate between the connecting plates 104 through the rotating plate 302, so that the covering cylinder 301 can be turned over and unfolded from one end of the air supply pipe 103 to display the air filter element 405 in the air supply pipe 103 to the outside, and then the staff can hold the handle 4 06 and twist it clockwise, so that the handle 406 can drive the limit block 407 on the outer surface of the air filter element 405 to rotate in the limit groove 404 of the convex ring 402, until it rotates to the end of the limit groove 404 so that the limit block 407 can be flush with the insertion port 403, and then the staff can pull the handle 406 to drive the limit block 407 on the outer surface of the air filter element 405 to be pulled out from the insertion port 403, thereby realizing the removal of the air filter element 405. During installation, it is only necessary to insert the limit block 407 on the outer surface of the air filter element 405 into the insertion port 403 and twist it counterclockwise, so as to realize the locking of the air filter element 405 in the convex ring 402, and then the covering cylinder 301 can be turned over again to cover one end of the air supply pipe 103.The butterfly bolt 305 is screwed and installed into the installation box 1, so that the covering tube 301 can touch one end of the air supply pipe 103 through the thread pressure of the butterfly bolt 305 and connect with it.

[0049] In summary: The ventilation device with a purification structure for clean rooms has the advantage of convenient disassembly and assembly of the air filter element 405, and the whole process does not require complicated tools or professional skills, which reduces the difficulty of maintenance and reduces the maintenance time. In addition, due to the simple disassembly and replacement operation, the air filter element 405 can be maintained quickly, thereby reducing the time when the entire air supply and filtration system stops operating due to filter element maintenance. At the same time, the exhaust wind direction can also be regulated, so that in a clean room with a complex layout, it can accurately control the air flow direction and exhaust position according to the equipment layout, work flow, etc. in different areas, so as to avoid the impact of air turbulence on the clean room environment.
