Description

Technical Field

[0001] The invention relates to the technical field of modular air clean rooms for clean workshops, in particular to a modular air clean room for clean workshops. Background Art

[0002] The "modularity" in the modular air clean room of the clean room refers to a design concept and construction method, which involves breaking down the clean room into multiple relatively independent functional modules with clear functions, and then combining and installing them according to actual needs. Modular air clean room, also known as assembled clean room, refers to the use of modular design and construction technology to divide the clean room into multiple relatively independent functional modules, such as the main frame, doors and windows, purification equipment, etc., and then personalized design and production according to customer needs, and quickly transported to the site for assembly. This clean room system has the characteristics of flexible assembly, easy maintenance and upgrading, strong adaptability, and low cost.

[0003] The humidity requirement of existing clean rooms is 40%-60%RH (the electronic manufacturing industry and SMT dust-free workshops require humidity between 45%-55%RH, and the pharmaceutical industry requires humidity between 45%-60%RH). If the sterilized and filtered dry air continues to enter the room, it will inevitably break the humidity balance in the room and affect the yield rate of the product. Although the clean room will use a special humidity control device to adjust the humidity inside the room, such as using surface coolers, reheaters and other equipment to cool and dehumidify in summer, and using isenthalpic heating or isothermal humidification processes to humidify the air in winter, and the dry air continues to enter the room, the fixed air outlet will form a dry air area with low humidity, while the humidity in the room far away from the air outlet is relatively high, resulting in uneven internal humidity in the entire room.

DETAILED DESCRIPTION

[0037] The following will be described clearly and completely in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Embodiment, a modular air clean room for a clean factory, such as Figure 1As shown, the clean room includes a clean room having a plurality of side panels 2 and a plurality of ceilings 1. The plurality of side panels 2 are combined to form a rectangular frame. The side panels 2 can be metal plates or sandwich panels. A connecting plate 201 is provided between two adjacent side panels 2. The plurality of ceilings 1 are spliced ​​together to form a top plate covering the upper end of the rectangular frame.

[0039] Specifically, Figure 3 As shown, the upper and lower ends of the two side walls of the connecting plate 201 are fixed with limit plugs 202, and the side walls at both ends of the side panels 2 are provided with T-shaped sockets. The two limit plugs 202 at the same end of the connecting plate 201 are inserted into the corresponding T-shaped sockets; in this way, the two adjacent side panels 2 can be spliced ​​together, and the corresponding number of side panels 2 can be selected for assembly according to the length and width requirements of the clean room. The lower two limit plugs 202 at the same end are inserted from top to bottom along the T-shaped socket, which can reduce the friction resistance during insertion. Compared with the use of limit blocks as large as the T-shaped socket, the installation is easier and more labor-saving.

[0040] The connecting plate 201 here is a rectangular structure or an L-shaped structure, such as Figure 5 As shown, when two adjacent side panels 2 are connected together in parallel, the connecting plate 201 is a rectangular structure. When two adjacent side panels 2 are distributed at 90°, the connecting plate 201 adopts an L-shaped structure to ensure that multiple side panels 2 can be enclosed into a rectangular structure according to usage needs.

[0041] For the assembly of the ceiling 1, a docking block 101 is provided at the upper edge of the ceiling 1, and a docking screw 103 is inserted between the docking blocks 101 of two adjacent ceilings 1. The axial ends of the docking screw 103 are both threadedly connected with a fastening cap 104. Figure 2 As shown, multiple ceilings 1 are horizontally spliced ​​together, and the docking blocks 101 of two adjacent ceilings 1 are docked together, and then the docking screws 103 are passed through the two docking blocks 101, and the fastening caps 104 are threadedly connected at both axial ends of the docking screws 103, so that multiple ceilings 1 are assembled together, and then a sinking installation hole 102 is opened on the side edge of the ceiling 1, and a self-tapping screw that can be drilled into the upper end of the side panel 2 is provided in the sinking installation hole 102, so that multiple ceilings 1 are stably installed on the rectangular frame composed of multiple side panels 2. An entry and exit door is hinged on one of the side panels 2, and multiple side panels 2, the entry and exit door and multiple ceilings 1 form a clean room. When in use, multiple clean rooms are set according to the planning and use requirements in the factory, and can be installed in the preset position. The entry and exit door is opened to enter and exit each independent clean room.

[0042] Furthermore, in order to enhance the supporting stability of the rectangular frame, e.g. Figure 4 and Figure 5As shown, a threaded hole penetrating the T-shaped socket is opened on the side wall of the side panel 2, and a threaded column 203 is threadedly inserted in the threaded hole. At least two threaded columns 203 are provided at the same end of the side panel 2. In this state, the radial side walls of the two threaded columns 203 are respectively fitted with the opposite side walls of the two limit blocks 202 at the same end, which can prevent the limit blocks 202 from sliding up and down along the T-shaped socket at will, thereby ensuring that the two adjacent side panels 2 are stably connected together.

[0043] After the clean room is assembled, the indoor air needs to be humidified to meet the use needs in winter or dry environments, so as to meet the product processing humidity requirements. The electronics manufacturing industry and SMT dust-free workshops require humidity between 45%-55%RH, and the pharmaceutical industry requires humidity between 45%-60%RH. At present, the commonly used method is to place a humidification device inside the clean room. For example, in summer, surface coolers, reheaters and other equipment are used for cooling and dehumidification, and in winter, isenthalpic heating or isothermal humidification processes are used to humidify the air. Although this can meet the humidification needs, according to the "Cleanroom Design Code" (GB50073-2013), the ventilation frequency of Class 6 (1000) clean rooms should be 50-60 times / hour, and the ventilation frequency of Class 7 (10000) clean rooms should be 15-25 times / hour. For Class 1000 chip clean rooms, the ventilation frequency is usually 20-30 times / hour; the per capita fresh air volume in the clean room should not be less than 40m 3 / h, the per capita fresh air volume in a closed workshop should be designed to be 30m 3 / h-50m 3 / h, it can be seen that the ventilation frequency and wind speed of the clean room have clear requirements, and clean air needs to be continuously provided to the inside of the clean room.

[0044] If clean dry air is introduced into the clean room, as the dry air continuously enters the clean room, a dry air zone will be formed at and around the dry air outlet, where the humidity is relatively low, while the humidity indoors far from the outlet is relatively high, resulting in uneven indoor humidity, which affects the product yield.

[0045] like Figure 1 , Figure 6 and Fig.11As shown, the bottom opening of the air outlet is connected with a humidifying component. The humidifying component and the air outlet are arranged together to humidify the wind at the air outlet, so that the wind entering the clean room is moist wind, that is, the wind entering the clean room has a certain humidity, rather than dry wind, and no dry wind area is formed. The humidifying component has a shell 3, a support plate 1 9 and a support plate 2 10. A shell cover 12 is detachably provided at the upper end of the shell 3. The shell cover 12 is arranged at the upper end of the shell 3 in a threaded connection. The shell cover 12 is unscrewed from the upper end of the shell 3, and then clean water is filled into the shell 3, and then the shell 3 and the shell cover 12 are rotatably connected together. A ventilation hanging pipe 31 is inserted at the upper end of the shell cover 12, and a hanging plate 32 is fixedly sleeved on the upper end of the outer wall of the ventilation hanging pipe 31. A plurality of mounting ear plates are fixed on the radial side wall of the hanging plate 32. A butt pipe 33 is slidably inserted at the upper end of the ventilation hanging pipe 31, and the butt pipe 33 is butt-jointed with the bottom opening of the air outlet. An air vent is provided on one of the ceilings 1, and an FFU unit (the FFU unit is a fan filter unit or a fan filter unit, which is an air filter system with a built-in fan) is installed on the upper end of the ceiling 1. The air outlet of the FFU unit is connected to the opening at the upper end of the air vent, and then the air is sent into the shell 3 through the docking pipe 33 and the ventilation hanging pipe 31.

[0046] Moreover, if Figure 7 and Figure 8 As shown, support disk 19 is rotatably arranged on the inner top wall of the shell cover 12, support disk 19 is coaxially arranged with support disk 2 10, and a sleeve rod 18 is fixed between support disk 19 and support disk 2 10, a motor 8 is fixed on the inner top wall of the shell cover 12, support disk 19 is fixed at the output end of the motor 8, support disk 19 is coaxially arranged with support disk 2 10, and a sleeve rod 18 is fixed between support disk 19 and support disk 2 10, the motor 8 drives support disk 19 to rotate, and through the linkage of the sleeve rod 18, support disk 2 10 rotates synchronously.

[0047] A water-absorbing cotton disc 15 is rotatably sleeved outside the sleeve rod 18, and a vertical tube 14 is fixedly inserted at the bottom end of the outer wall of the water-absorbing cotton disc 15. A water-absorbing cotton stick 21 is inserted in the vertical tube 14, and the upper end of the water-absorbing cotton stick 21 is in contact with the water-absorbing cotton disc 15, and the bottom end of the vertical tube 14 extends to the inner bottom wall of the shell 3. When the sleeve rod 18 rotates following the support plate 1 9, the water-absorbing cotton disc 15 rotates relative to the outer wall of the sleeve rod 18, that is, the water-absorbing cotton disc 15 does not rotate, and the water-absorbing cotton stick 21 absorbs the clean water in the shell 3 and transmits it to the water-absorbing cotton disc 15. The axial length of the sleeve rod 18 is set equal to the axial length of the water-absorbing cotton disc 15, and the axial side wall of the water-absorbing cotton disc 15 can be in contact with the axial side wall of the support plate 2 10 in real time, providing clean water for the ultrasonic atomization sheet 16 to atomize.

[0048] like Fig.10As shown, an embedded hole is opened at the edge of the axial side wall of the support disk 2 10, and an ultrasonic atomization sheet 16 is built in the embedded hole. The ultrasonic atomization sheet 16 follows the rotating support disk 2 10 to make a circular motion; a lithium battery is used to provide power for the ultrasonic atomization sheet 16. The ultrasonic atomization sheet 16 serves as an atomization and humidification component. An opening is opened on the side of the shell cover 12, and a wide mask 4 is fixed to the side wall of the opening. The ultrasonic atomization sheet 16 is located at the opening. The rotating ultrasonic atomization sheet 16 drives the sprayed water mist to be sprayed out in a rotating manner, thereby expanding the spraying range of the water mist, and then it is sprayed out through the opening of the wide mask 4 for atomization and humidification of the air.

[0049] like Fig.10 As shown, the axial length of the sleeve rod 18 is equal to the axial length of the water-absorbing cotton disc 15; at the same time, a protrusion 19 horizontally opposite to the ultrasonic atomizing sheet 16 is fixed to the axial side wall of the supporting disc 1 9. The water-absorbing cotton disc 15 is clamped between the supporting disc 1 9 and the supporting disc 2 10, and the protrusion 19 is used to push the water-absorbing cotton disc 15 facing the ultrasonic atomizing sheet 16 toward the ultrasonic atomizing sheet 16, so as to ensure that the water-absorbing cotton disc 15 can be further fitted with the ultrasonic atomizing sheet 16, so as to ensure that the water supply of the ultrasonic atomizing sheet 16 is satisfied.

[0050] After the existing humidifier is fixedly placed, the ultrasonic atomizing sheet 16 sprays water mist of a columnar structure from the mist outlet, and the range of the spray humidification is not adjustable. The rotating ultrasonic atomizing sheet 16 can diffuse the sprayed water mist in the wide mask 4 and spray it out from the opening of the wide mask 4, thereby expanding the spray range. In order to further increase the spray range of the atomization, a rubber hose 11 is fixed to the side wall of the embedded hole opening, and the end of the rubber hose 11 is connected to a guide pipe 5 extending to the inside of the wide mask 4. A support plate 10 is rotatably provided with a support rod 6 on the axial side wall, and the support rod 6 is fixedly sleeved with an articulated seat 13, and the end of the articulated seat 13 is hinged to the outer wall of one end of the guide pipe 5 close to the rubber hose 11, such as Fig. 9 As shown, the outer wall of the guide pipe 5 is hinged to the end of the hinge seat 13. When the support plate 10 rotates at the opening, the guide pipe 5 can make a circular motion with the center of the support plate 10 as the center. When the guide pipe 5 rotates, the guide pipe 5 is affected by the centrifugal force and rotates to the side away from the support rod 6 with the hinged position with the hinge seat 13 as the center, which expands the radius of the circular structure formed by the rotation of the guide pipe 5, that is, the water mist derived from the guide pipe 5 is expanded, thereby expanding the spray range. At the same time, a humidity sensor can be installed at the opening position of the wide mask 4. The model is TH05E02-W01, which is used to monitor the humidity of the derived wind in real time.

[0051] A guide tube 5 capable of making circular motion in the wide mask 4 is used to spray the water mist sprayed from the mist outlet of the ultrasonic atomizing piece 16 in a rotating manner. During the rotation, the water mist is not only sprayed in the direction derived from the axial direction of the guide tube 5, but also sprayed in a circular structure formed by the rotation of the guide tube 5. The centrifugal force formed by the rotation of the guide tube 5 drives the sprayed water mist to disperse toward the outside of the guide tube 5, and the spray coverage area is expanded, which solves the problem that the water mist of the columnar structure sprayed from the mist outlet of the ultrasonic atomizing piece 16 has no adjustable spray range and cannot meet more atomization and humidification needs.

[0052] A notch 17 is provided on the outer wall of one end of the guide tube 5 away from the rubber hose 11. After the water mist is discharged from the rubber hose 11, it is transmitted along the guide tube 5 and enters the space inside the wide mask 4 from the notch 17. The rotating guide tube 5 is used to stir the water mist sprayed into the wide mask 4 to accelerate its flow rate, so that the water mist sprayed from the wide mask 4 can diffuse in a wider range along the radial direction of the opening of the wide mask 4, and the spray coverage area can be larger, thereby meeting the atomization needs in a larger range.

[0053] Compared with the method in which the water mist is sprayed only from one end of the guide pipe 5 away from the rubber hose 11, the water mist is pre-accelerated in the wide mouth 4 to increase its diffusion range, thereby maximizing the humidification area.

[0054] Further, such as Fig. 9 As shown, the outer wall of the support rod 6 is threadedly connected with an adjusting disk, and the radial side wall of the adjusting disk is fixed with an arc-shaped supporting piece 7, and the end of the arc-shaped supporting piece 7 is fixedly connected to the outer wall of the end of the guide tube 5 away from the rubber hose 11. By rotating the support rod 6, the adjusting disk can be adjusted along the axial direction of the support rod 6, that is, the position of the arc-shaped supporting piece 7 can be adjusted, so that the guide tube 5 can be linked to rotate around the hinge with the hinge seat 13, and the angle between the guide tube 5 and the support rod 6 can be adjusted to adjust the radius of the water mist formed by the rotation of the guide tube 5.

[0055] The arc-shaped support piece 7 is arranged to pull the guide tube 5 to rotate around the hinge of the hinge seat 13, so that the angle between the guide tube 5 and the support rod 6 can be accurately adjusted. The adjusted guide tube 5 will not be affected by the centrifugal force generated by the rotation, and can be flipped around the hinge position at will, so as to accurately control the circular water mist spraying range formed by the rotation of the guide tube 5. The user can adjust it according to the requirements of the atomization and humidification range.

[0056] The humidifier in the prior art has high requirements for water quality. If the water quality is hard, it will cause scale to appear inside the humidifier, which will affect the normal operation of the humidifier. Therefore, after the absorbent cotton swab 21 is used for a long time, scale impurities mixed in the water will remain in the absorbent cotton swab 21, affecting the water absorption of the absorbent cotton swab 21. This will affect the water absorption of the absorbent cotton disk 15 to supply water to the ultrasonic atomizer 16, thereby affecting the amount of water mist sprayed. While the absorbent cotton swab 21 absorbs water, it also acts as a filter to filter scale impurity particles mixed in the water. After long-term use, it is pulled out from the bottom of the vertical tube 14 and a new absorbent cotton swab 21 is inserted into the vertical tube 14 to ensure adsorption performance. Fig.11 As shown, the bottom end of the vertical cylinder 14 extends to the inner bottom wall of the shell 3, and a plurality of liquid inlet notches are provided on the radial side wall of the bottom end of the vertical cylinder 14. The plurality of liquid inlet notches not only do not affect the entry of clean water into the vertical cylinder 14, but also can block the entry of impurity particles into the vertical cylinder 14 to the greatest extent.

[0057] like Fig.12 As shown, an annular reinforcement frame 20 is fixed on the upper end of the vertical tube 14, and the annular reinforcement is fixedly embedded in the absorbent cotton disk 15; the annular reinforcement is fixedly embedded in the absorbent cotton disk 15, and by embedding the annular reinforcement frame 20 in the absorbent cotton disk 15, the strength of the connection between the vertical tube 14 and the absorbent cotton disk 15 can be enhanced.

[0058] In summary, modular air clean rooms are widely used in industries that require a high cleanliness environment, such as optoelectronics, electronics, biomedicine, precision manufacturing, etc. These industries have extremely high requirements for the cleanliness of the production environment, and modular air clean rooms can meet their needs and provide a stable and reliable clean environment.
