Description

Technical Field

[0001] This utility model relates to the field of filters, and in particular to a detachable high-efficiency filter device for electronic cleanrooms. Background Technology

[0002] Electronic manufacturing plants are industrial buildings specifically designed for the production and manufacturing of electronic products. Their core characteristics include a highly clean production environment, stable temperature and humidity control, and strict anti-static measures. These plants are typically equipped with high-efficiency air filtration systems, laminar flow cleanrooms, and precision air conditioning systems to ensure a dust-free and pollution-free production process, meeting the special requirements of precision manufacturing industries such as semiconductors, LCD panels, and microelectronics for air cleanliness, vibration control, and electromagnetic shielding.

[0003] To ensure the environment inside the electronics factory, the filter elements of the filtration device need to be replaced regularly. However, the filter elements are mostly located inside the housing and are fixed with bolts, making disassembly and replacement inconvenient. At the same time, the air supply system of the filtration device needs to be stopped during the filter element replacement process, which will cause a gap in the filtration and reduce the filtration efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a detachable high-efficiency filter device for electronic cleanrooms, thereby improving the efficiency of filter element replacement and the overall filtration efficiency of the device.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A detachable high-efficiency filter device for electronic cleanrooms includes:

[0007] The transmission housing is used for support. An air inlet pipe is fixedly connected to the left side of the transmission housing, and an exhaust pipe is fixedly connected to the right side of the air inlet pipe. Mounting slots are opened on both the front and rear sides of the transmission housing. Transmission slots are opened on both sides of the mounting slots. Filter blocks are nested inside the mounting slots. Filter frames are slidably connected to the inner center of the filter blocks. Mounting frames are fixedly connected to the rear end of the filter frames. Filter elements are nested inside the filter frames. The inner side of the mounting frames is nested outside the filter blocks. Quick-release limiting components are installed on both sides of the filter blocks to enable quick replacement of the internal filter elements.

[0008] Multiple limiting posts are used for the top left side of the transmission housing. Anti-clogging L-plates are slidably connected to the outside of the limiting posts. The bottom two sides of the anti-clogging L-plates are connected to the top of the transmission housing by tension springs. A positioning component is installed on the top of the transmission housing to the left of the limiting posts so that the device can continue to perform filtration when the filter element is replaced.

[0009] Furthermore, the positioning component includes a support plate fixed on the top left side of the transmission housing, a positioning insert plate inserted inside the support plate, and the outside of the positioning insert plate inserted into the lower groove of the anti-blocking L plate. Magnetic blocks are fixedly connected to both the upper and lower sides of the positioning insert plate, and the inner side of the magnetic block is magnetically attracted to the outer side of the support plate.

[0010] Furthermore, the quick-release limiting assembly includes a conveying pipe that slides on both sides of the filter block. Each conveying pipe is fixedly connected to a compression mounting ring. Each compression mounting ring is fixedly connected to a toggle plate on both the upper and lower sides. The toggle plates are slidably connected to the upper and lower sides of the filter block. The inner side of the compression mounting ring is connected to the interior of the filter block through a compression spring.

[0011] Furthermore, anti-detachment frames are fixedly connected to both the outer and inner sides of the conveying pipe to protect it from detachment.

[0012] Furthermore, a sealing soft rubber sleeve is fixedly connected to the outside of the filter frame, and the outside of the sealing soft rubber sleeve is nested in the inner groove of the filter block.

[0013] Furthermore, the outer surface of the conveying pipe is respectively inserted into the interior of the conveying slot.

[0014] Furthermore, a limiting plate is fixedly connected to the top of the limiting post.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, by simultaneously applying force inward to the actuating plate and generating an inward pulling force through the squeezing of the mounting ring, the conveying pipe is disassembled from the inside of the transmission slot, thereby removing the filter block and pulling the mounting frame outward, thus replacing the internal filter element, improving the efficiency of filter element replacement and facilitating daily use of the device.

[0017] 2. In this utility model, when replacing the filter element, the positioning insert plate on the disassembly side is pulled outward to disengage the positioning insert plate from the bottom of the anti-clogging L plate. After the filter block is pulled outward, the tension spring exerts a downward pulling force on the anti-clogging L plate, thereby blocking and sealing the transmission slot. The device can continue to work during the filter element replacement process, improving the filtration efficiency of the device. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 , Figure 2 and Figure 5This utility model provides an embodiment of a detachable high-efficiency filter device for electronic cleanrooms, comprising: a transmission housing 1 for support; an air inlet pipe 2 fixedly connected to the left side of the transmission housing 1; an exhaust pipe 6 fixedly connected to the right side of the air inlet pipe 2; mounting slots 13 on both the front and rear sides of the transmission housing 1; transmission slots 12 on both sides of the mounting slots 13; filter blocks 7 nested inside each mounting slot 13; a filter frame 19 slidably connected to the inner center of the filter block 7; a mounting frame 5 fixedly connected to the rear end of the filter frame 19; a filter element 18 nested inside the filter frame 19; the inner side of the mounting frame 5 nested outside the filter block 7; and quick-release limiting components installed on both sides of the filter block 7 for use with... To enable quick replacement of the internal filter element, the quick-release limiting assembly includes a conveying pipe 20 that slides on both sides of the filter block 7. Each conveying pipe 20 is fixedly connected to a compression mounting ring 21. Each compression mounting ring 21 is fixedly connected to both the upper and lower sides of the compression mounting ring 21. The upper and lower sides of the compression mounting ring 8 are slidably connected to the upper and lower sides of the filter block 7. The inner side of the compression mounting ring 21 is connected to the inside of the filter block 7 through a compression spring 22. Both the outer and inner sides of the conveying pipe 20 are fixedly connected to an anti-detachment frame 16 to protect the conveying pipe 20 from detachment. The outer side of the filter frame 19 is fixedly connected to a sealing soft rubber sleeve 17. The outer side of the sealing soft rubber sleeve 17 is nested in the inner groove of the filter block 7. The outer side of the conveying pipe 20 is respectively inserted into the inside of the transmission groove 12.

[0027] The air supply system delivers air into the transmission housing 1 through the air inlet pipe 2. The air enters the delivery pipe 20 through the transmission slot 12, and then enters the filter block 7. The delivery pipe 20 guides the air directly to the outside of the filter frame 19. After the air passes through the filter element 18 and is filtered, it enters the exhaust pipe 6 through the right delivery pipe 20. When replacing the filter element, simply squeeze the actuating plate 8 inward. Through the transmission action of the mounting ring 21, the delivery pipe 20 is disengaged from the transmission slot 12, and the filter block 7 can be removed. At this time, pull the mounting frame 5 outward, and the filter frame 19 slides out, making it easy to remove the filter element 18 for replacement. Finally, align the mounting frame 5 with the mounting slot 13 and push it in to complete the entire replacement process. This design significantly improves the ease of operation for filter element replacement.

[0028] Reference Figure 1 , Figure 3 and Figure 4Multiple limiting posts 15 are used for the top left side of the transmission housing 1. The limiting posts 15 are slidably connected to the outside of the anti-blocking L plate 9. The bottom two sides of the anti-blocking L plate 9 are connected to the top of the transmission housing 1 by tension springs 4. A positioning component is installed on the top of the transmission housing 1 to the left of the limiting posts 15, so that the device can continue to perform filtration when the filter element is replaced. The positioning component includes a support plate 3 fixed on the top left side of the transmission housing 1. A positioning insertion plate 11 is inserted inside the support plate 3. The outside of the positioning insertion plate 11 is inserted into the lower groove of the anti-blocking L plate 9. Magnetic blocks 14 are fixedly connected to the upper and lower sides of the positioning insertion plate 11. The inside of the magnetic blocks 14 is magnetically attracted to the outside of the support plate 3. A limiting plate 10 is fixedly connected to the top of the limiting posts 15.

[0029] When it is necessary to disassemble one side of the filter block 7, first pull out the positioning insertion plate 11 on the corresponding side to separate it from the bottom of the anti-blocking L plate 9. After disassembling the filter block 7, the downward force generated by the tension spring 4 causes the anti-blocking L plate 9 to automatically close the transmission slot 12 on that side. At this time, all the air will be filtered through the other side of the filter block 7. This alternating design not only ensures the continuity of the filtration process, but also significantly improves the operating efficiency of the device.

[0030] Working principle: Air is supplied through the air supply system via the intake pipe 2 to the inside of the transmission housing 1. The air circulates inside the transmission housing 1, passing through the transmission slot 12 to the inside of the delivery pipe 20, thus entering the filter block 7. The delivery pipe 20 directly delivers the air to the outside of the filter frame 19. The air passes through the inside of the filter element 18, thus being filtered, and then passes through the right-side delivery pipe 20 into the exhaust pipe 6. When replacing the filter element, a squeezing force is simultaneously applied to the actuating plate 8, which, through the squeezing of the mounting ring 21, disengages the delivery pipe 20 from the inside of the transmission slot 12, thereby disassembling the filter block 7. At this time, the mounting frame 5 is pulled outwards, the filter frame 19 slides outwards, and the filter element 18 is removed. Pull upwards to remove and replace, then reinstall the filter block 7 by placing the mounting frame 5 inside the mounting slot 13. The inclined surface 20 contacts the inclined surface outside 13, and automatically retracts inward due to the squeezing force. When it moves inside 12, it pops outward to complete the installation, improving the convenience of filter replacement. At the same time, when disassembling a single side of the filter block 7, pull the positioning insertion plate 11 of the side to be disassembled outward to separate it from the bottom end of the anti-clogging L plate 9. After the filter block 7 is disassembled, the tension spring 4 exerts a downward pulling force on the anti-clogging L plate 9, thereby sealing the transmission slot 12 on one side of the anti-clogging L plate 9, and the input air is directly filtered through the filter block 7 on the other side. This alternating process improves the filtration efficiency of the device.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
