Description

Technical Field

[0001] This utility model relates to the field of cleanroom filtration, and in particular to a cleanroom filtration device with a quick-replaceable filter element. Background Technology

[0002] A cleanroom, also known as a clean space, is a specially designed environment to maintain extremely high air quality standards. It provides a highly clean space by controlling parameters such as the concentration of airborne particles, temperature, humidity, and pressure. Cleanrooms are widely used in industries that require strict pollution control. In cleanrooms and other environments that require high cleanliness, filtration devices play a crucial role.

[0003] Current cleanroom filtration installation typically involves placing the filter cartridge in a mounting box, then rotating the latches to secure the four corners of the filter cartridge, followed by tightening the screws before using the installed equipment. However, the current method requires manual intervention with auxiliary tools to repeatedly tighten or loosen multiple screws, and then rotating the latches to install and remove the filter cartridge. This operation is cumbersome, time-consuming, and makes it difficult to quickly replace, repair, and remove the filter cartridge, resulting in low replacement efficiency and significant inconvenience.

[0004] Therefore, there is a need to design a cleanroom filtration device that allows for quick filter element replacement, installation and use when the cover is opened and limited when the cover is closed, so as to facilitate quick replacement, maintenance and installation / removal of the filter element without the need for auxiliary tools, thereby improving replacement efficiency and operational stability. Utility Model Content

[0005] To overcome the shortcomings of current methods that require manual tightening or loosening of multiple screws with the aid of auxiliary tools, followed by rotating the buckle to install or remove the filter element, which is cumbersome, time-consuming, and makes it difficult to quickly replace, repair, and install / remove the filter element, resulting in low replacement efficiency, this utility model provides a cleanroom filtration device that allows for quick filter element replacement. This device allows for filter element installation and use when the cover is rotated open, and for limiting the filter element when the cover is closed. This facilitates quick filter element replacement, repair, and installation / removal without the need for auxiliary tools, improving replacement efficiency and operational stability.

[0006] The technical solution of this utility model is as follows: a cleanroom filtration device with quick filter replacement, comprising a ventilation frame, a filter element, a shielding cover, a limiting knob, a limiting component, and a driving component. The filter element is placed on the ventilation frame. The shielding cover is rotatably connected to the right side of the ventilation frame. The limiting knob is rotatably connected to the upper left side of the ventilation frame through damping. The limiting knob contacts the shielding cover. A limiting component for fixing and limiting the filter element is provided between the ventilation frame and the shielding cover. A driving component is provided between the ventilation frame and the limiting component.

[0007] Furthermore, the shape of the limiting knob matches the shape of the groove on the cover.

[0008] Furthermore, the limiting assembly includes a squeezing block, a limiting frame, a first telescopic spring, a first pressing frame, a first roller, a second pressing frame, a second roller, and a second telescopic spring. The squeezing block is connected to the right side of the cover. The limiting frames are slidably connected to both the left and right sides of the ventilation frame. The limiting frames are snapped into the filter element. Two first telescopic springs are connected between the limiting frames and the ventilation frame. The first pressing frame is slidably connected to the upper right side of the ventilation frame. Two first rollers are rotatably connected to the left side of the first pressing frame. The first rollers are in contact with the limiting frame on the right side. The second pressing frame is slidably connected to the right side of the first pressing frame. The second roller is rotatably connected to the upper part of the second pressing frame. A second telescopic spring is connected between the second pressing frame and the first pressing frame.

[0009] Furthermore, the specifications of the second roller are all larger than those of the first roller.

[0010] Furthermore, the drive assembly includes a first rack, a gear, and a second rack. The first rack is connected to both the front and rear sides of the right-side limiting frame, and the gear is rotatably connected to both the front and rear inner sides of the ventilation frame. The first rack meshes with the gear on the same side. The second rack is connected to both the front and rear sides of the left-side limiting frame, and the second rack meshes with the gear on the same side.

[0011] Furthermore, the shape of the first rack is consistent with the shape of the second rack.

[0012] The present invention has the following advantages: 1. By rotating the cover switch, the pressing block is pressed or disengaged from the second roller, causing the second and first pressing frames to move or reset, and the limiting frame to move or reset, so that the filter element can be taken out or installed. Thus, the filter element can be installed and used when the cover is turned open, and the filter element is limited when the cover is closed. This facilitates quick replacement, maintenance and installation and removal of the filter element without the need for auxiliary tools, thereby improving replacement efficiency and usage stability.

[0013] 2. After the filter element is installed and fixed, the reverse rotation of the limiting knob resets the shielding cover to limit its position. Then, the device is installed in a clean room for filtration. This device can limit the shielding cover while protecting the filter element, preventing the shielding cover from opening accidentally, preventing damage to the filter element, extending the service life of the equipment, and further improving the stability of use.

Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0022] A cleanroom filtration device with a quick-change filter element, such as Figures 1-6 As shown, the device includes a ventilation frame 1, a filter element 2, a shielding cover 3, a limiting knob 4, a limiting component, and a driving component. The filter element 2 is placed on the ventilation frame 1. The shielding cover 3 is rotatably connected to the right side of the ventilation frame 1. The limiting knob 4 is rotatably connected to the upper left side of the ventilation frame 1 via damping. The limiting knob 4 contacts the shielding cover 3. The shape of the limiting knob 4 is consistent with the shape of the groove on the shielding cover 3. A limiting component for fixing and limiting the filter element 2 is provided between the ventilation frame 1 and the shielding cover 3. A driving component is provided between the ventilation frame 1 and the limiting component.

[0023] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the limiting assembly includes a squeezing block 5, a limiting frame 6, a first telescopic spring 7, a first pressing frame 8, a first roller 9, a second pressing frame 10, a second roller 11, and a second telescopic spring 12. The squeezing block 5 is connected to the right side of the cover 3. The limiting frame 6 is slidably connected to both the left and right sides of the ventilation frame 1. The limiting frame 6 is engaged with the filter element 2. Two first telescopic springs 7 are connected between the limiting frame 6 and the ventilation frame 1. The first pressing frame 8 is slidably connected to the upper right side of the ventilation frame 1. Two first rollers 9 are rotatably connected to the left side of the first pressing frame 8. The first rollers 9 are in contact with the limiting frame 6 on the right side. The second pressing frame 10 is slidably connected to the right side of the first pressing frame 8. The second roller 11 is rotatably connected to the upper part of the second pressing frame 10. The specifications of the second roller 11 are all larger than the specifications of the first roller 9. The second telescopic spring 12 is connected between the second pressing frame 10 and the first pressing frame 8.

[0024] like Figure 2 and Figure 6 As shown, the drive assembly includes a first rack 13, a gear 14, and a second rack 15. The first rack 13 is connected to both the front and rear sides of the right-side limiting frame 6. The gear 14 is rotatably connected to both the front and rear inner sides of the ventilation frame 1. The first rack 13 meshes with the gear 14 on the same side. The second rack 15 is connected to both the front and rear sides of the left-side limiting frame 6. The second rack 15 meshes with the gear 14 on the same side. The shape of the first rack 13 is the same as the shape of the second rack 15.

[0025] When the filter element 2 in the filtration equipment in the cleanroom needs to be replaced, this device can be used. By rotating the limiting knob 4 to a suitable angle, the cover 3 is opened, causing the pressing block 5 to rotate and press the second roller 11. This causes the second roller 11 to rotate and move, moving the second pressing frame 10 and the first pressing frame 8. This causes the first roller 9 to move and rotate, and under the action of friction, the right-side limiting frame 6 moves. The right-side first telescopic spring 7 is compressed, causing the first rack 13 to move. The first rack 13 meshes with the gear 14, causing the gear 14 to rotate. The gear 14 meshes with the second rack 15, causing the left... The limiting frame 6 of the right part moves, causing the first telescopic spring 7 of the left part to be compressed. When the limiting frame 6 of the right part can no longer move, and the cover 3 is still rotating, the second pressing frame 10 and the second roller 11 will continue to move, and the second telescopic spring 12 will be stretched. Then the filter element 2 is placed on the ventilation frame 1 for installation. The specifications of the second roller 11 are all larger than the specifications of the first roller 9. Then the cover 3 is rotated to close, causing the pressing block 5 to rotate in the opposite direction and disengage from the second roller 11. The second telescopic spring 12 rebounds, the second pressing frame 10 moves in the opposite direction to reset, the first telescopic spring 7 rebounds, causing the limiting frame 6 of the right part to reset in the opposite direction, causing the first pressing frame 8 and the second roller 9 to move in the opposite direction to reset. The first roller 9 moves in the reverse direction to reset, causing the first rack 13 to move in the reverse direction to reset. The first rack 13 meshes with the gear 14, causing the gear 14 to rotate in the reverse direction. The gear 14 meshes with the second rack 15, causing the left limiting frame 6 to move in the reverse direction to reset, causing the left first telescopic spring 7 to return. This allows the limiting frame 6 to engage with the filter element 2 for fixed positioning. The shape of the first rack 13 is consistent with the shape of the second rack 15. Then, the limiting knob 4 is rotated in the reverse direction to reset and limit the position of the cover 3. The shape of the limiting knob 4 is consistent with the shape of the groove on the cover 3. Next, the device is installed in a cleanroom for filtration. This device can limit the position of the cover 3 while protecting the filter element 2, preventing accidental opening of the cover 3, preventing damage to the filter element 2, extending the service life of the equipment, and improving the stability of use. When the filter element 2 is damaged and needs to be replaced or repaired, the cover 3 is opened by rotating the limiting knob 4 to a suitable angle, causing the pressing block 5 to rotate and press the second roller 11, causing the second roller 11 to rotate and move, causing the second pressing frame 10 and the first pressing frame 8 to move, causing the first roller 9 to move and rotate. Under the action of friction, the limiting frame 6 on the right moves, the first telescopic spring 7 on the right is compressed, and the first rack 13 moves.The first rack 13 meshes with the gear 14, causing the gear 14 to rotate. The gear 14 meshes with the second rack 15, causing the left limiting frame 6 to move. This compresses the left-side first telescopic spring 7. When the right-side limiting frame 6 can no longer move, and the cover 3 is still rotating, the second pressing frame 10 and the second roller 11 continue to move, stretching the second telescopic spring 12. The filter element 2 can then be removed for replacement. This allows the filter element 2 to be installed and used when the cover 3 is open, and to be limited when the cover 3 is closed. This facilitates quick replacement, maintenance, and removal of the filter element 2 without the need for auxiliary tools, improving replacement efficiency and operational stability. The above operation is then repeated to reinstall the filter element 2, after which the device can be used again.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
