Description

Technical Field

[0001] This utility model relates to the field of laminar flow hood technology, and in particular to an easily detachable cleanroom embedded laminar flow hood. Background Technology

[0002] A cleanroom is essentially a "controlled environment" that maintains the contamination level within a specific space below a preset threshold by strictly controlling key parameters such as airborne particles, microorganisms, temperature, humidity, pressure, and airflow. It is not simply a "clean room," but a complex system integrating air purification technology, building engineering, and environmental monitoring and management. Its core objective is to provide a "quantifiable and stable" low-contamination environment for scenarios such as precision manufacturing, aseptic production, and scientific experiments. Laminar flow cleanrooms are divided into vertical laminar flow and horizontal laminar flow. When used in cleanrooms, embedded laminar flow hoods are typically configured. Embedded laminar flow hoods are one of the core devices for achieving a high level of cleanliness in a localized environment, and their function revolves around "precise cleanliness control, stable airflow, and adaptation to the cleanroom layout."

[0003] In existing embedded laminar flow hoods, a hanging rod with hooks is pre-installed on the ceiling of the cleanroom during installation. The embedded laminar flow hood is then hung on the hooks using a lifting ring. Subsequently, a ceiling panel is installed around the outside of the laminar flow hood, with the operating position exposed below the ceiling panel. This type of embedded laminar flow hood often requires the removal of multiple surrounding ceiling panels for disassembly and maintenance, followed by lifting the laminar flow hood from the hooks. This makes the disassembly and maintenance of embedded laminar flow hoods in cleanrooms inconvenient. Therefore, we propose an easily disassembled embedded laminar flow hood for cleanrooms. Utility Model Content

[0004] The main objective of this invention is to provide a cleanroom embedded laminar flow hood that is easy to disassemble. A top-mounting mechanism is configured on the outside of the laminar flow hood body. This mechanism, consisting of a long support frame and side panels, is assembled at the cleanroom ceiling to create a structure that allows the laminar flow hood body to be lifted and moved laterally. A rubber plug is inserted between the long support frame, side panels, and the laminar flow hood body for sealing. After the laminar flow hood body is lifted by a lifting ring and hook frame after the top of the long support frame is exposed, workers can lift and move the laminar flow hood body laterally after removing the rubber plug, allowing the lifting ring to leave the hook and facilitating easy downward disassembly of the laminar flow hood body. This effectively solves the problems in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A detachable cleanroom embedded laminar flow hood includes a laminar flow hood body and a lifting ring. The lifting ring is installed at the top of the laminar flow hood body. It also includes a top-mounting mechanism, which comprises a long frame support plate, side vertical plates, rubber plug seats, a support plate, long bolts, tripod side frames, and U-shaped brackets. A long frame support plate is snapped onto the outer side of the laminar flow hood body below the lifting ring, and a side vertical plate protrudes downwards from one side of the long frame support plate. A rubber plug seat is snapped between the side vertical plate and the long frame support plate and the laminar flow hood body, and a long bolt is screwed between the rubber plug seat and the side vertical plate. Tripod side frames are symmetrically installed on both sides of the laminar flow hood body below the long frame support plate, and U-shaped brackets are welded to the outer sides of the two sets of tripod side frames. A support plate is adhered to the bottom of the rubber plug seat extending beyond the side vertical plate.

[0007] Furthermore, the top of the long frame support plate on the outer side of the laminar flow hood body is recessed with a groove for mounting the sealing top strip, and the sealing top strip is sleeved on the outer side of the laminar flow hood body.

[0008] By adopting the above technical solution, the sealing top strip can be snapped and bonded into the groove of the long frame support plate, so that when the laminar flow hood body is snapped and exposed upward from inside the long frame support plate, there is a sealing position.

[0009] Furthermore, the side vertical plate below the long frame support plate is fitted with a sealing gasket frame on the outer side of the laminar flow hood body;

[0010] By adopting the above technical solution, after the long frame support plate is clamped to the laminar flow hood body, the sealing gasket frame can press against the surface of the cleanroom ceiling panel under the long frame support plate and the side vertical plate to achieve sealing contact.

[0011] Furthermore, the side plate and the seat of the rubber plug are provided with mounting holes for screwing in long bolts;

[0012] By adopting the above technical solution, the long bolt can be screwed into the mounting hole of the rubber plug seat from the mounting hole of the side vertical plate, thereby providing support for the rubber plug seat at the side vertical plate.

[0013] Furthermore, the tripod side frame is provided with three sets of foot plates, and threaded holes for screwing bolts are provided between the foot plates of the tripod side frame and the laminar flow hood body.

[0014] By adopting the above technical solution, the three sets of foot plates of the tripod side frame are connected to the laminar flow hood body by bolts, and the tripod side frame or U-shaped support frame can be held to make it easy to lift the laminar flow hood body and change its position.

[0015] Furthermore, a pull rod is welded to the bottom surface of the tray away from the rubber plug seat;

[0016] By adopting the above technical solution, after the long bolt is rotated away from the side vertical plate, the pull rod can be held to pull the support plate and rubber plug seat downwards for disassembly.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This utility model involves configuring a top-mounting mechanism on the outside of the laminar flow hood body. The top-mounting mechanism is assembled at the cleanroom ceiling with a long support frame and side hanging plates to form a structure that allows the laminar flow hood body to be lifted and moved laterally. A rubber plug is inserted between the long support frame, side hanging plates and the laminar flow hood body for sealing. After the laminar flow hood body is lifted by the lifting ring and hook frame after the top of the long support frame is exposed, the worker can lift the laminar flow hood body to the side after the rubber plug is removed, so that the lifting ring leaves the hook, making it convenient to disassemble the laminar flow hood body downwards.

[0019] Furthermore, the long frame support plate is sealed and clamped to the top box of the laminar flow hood body with a sealing top strip, while the bottom of the long frame support plate is sealed and pressed against the ceiling plate to ensure a sealed contact, thus ensuring the sealed installation of the laminar flow hood body and the ceiling plate.

[0025] like Figures 1-3As shown, this embodiment provides a cleanroom embedded laminar flow hood that is easy to disassemble, including a laminar flow hood body 1 and a lifting ring 2. The lifting ring 2 is installed at the top of the laminar flow hood body 1. It also includes a top mounting mechanism 3, which includes a long frame support plate 4, side hanging plates 5, rubber plug seats 6, support plates 7, long support bolts 10, tripod side frames 11, and U-shaped brackets 12. The long frame support plate 4 is clamped to the outside of the laminar flow hood body 1 below the lifting ring 2, and the long frame... A side sill plate 5 protrudes downward from one side of the support plate 4. A rubber plug seat 6 is fitted between the side sill plate 5, the long frame support plate 4, and the laminar flow hood body 1. A long support bolt 10 is screwed between the rubber plug seat 6 and the side sill plate 5. Tripod side frames 11 are symmetrically installed on both sides of the laminar flow hood body 1 below the long frame support plate 4. U-shaped support frames 12 are welded to the outer sides of the two sets of frames of the tripod side frames 11. A support plate 7 is glued to the bottom of the rubber plug seat 6 extending out of the side sill plate 5.

[0026] The long frame support plate 4 on the outer side of the laminar flow hood body 1 has a recessed groove at the top for mounting the sealing top strip 13, and the sealing top strip 13 is fitted onto the outer side of the laminar flow hood body 1.

[0027] By adopting the above technical solution, the sealing top strip 13 can be snapped and bonded into the groove of the long frame support plate 4, so that when the laminar flow hood body 1 is snapped and exposed upward from inside the long frame support plate 4, there is a sealing position.

[0028] Among them, the side vertical plate 5 below the long frame support plate 4 and the outer side of the laminar flow hood body 1 are fitted with a sealing gasket frame 14.

[0029] By adopting the above technical solution, after the long frame support plate 4 is snapped into the laminar flow hood body 1, the sealing gasket frame 14 can press against the surface of the cleanroom ceiling panel below the long frame support plate 4 and the side vertical plate 5 to make sealing contact.

[0030] The side plate 5 and the rubber plug seat 6 are provided with mounting holes 9 for screwing in the long bolt 10.

[0031] By adopting the above technical solution, the long bolt 10 can be screwed into the mounting hole 9 of the rubber plug seat 6 from the mounting hole 9 of the side vertical plate 5, thereby providing support for the rubber plug seat 6 at the side vertical plate 5.

[0032] The tripod side frame 11 has three sets of foot plates on its frame body, and threaded holes for screwing bolts are opened between the foot plates of the tripod side frame 11 and the laminar flow hood body 1.

[0033] By adopting the above technical solution, after the three sets of foot plates of the tripod side frame 11 are connected to the laminar flow hood body 1 by bolts, the tripod side frame 11 or the U-shaped support frame 12 can be held to facilitate lifting the laminar flow hood body 1 and changing its position.

[0034] A pull rod 8 is welded to the bottom surface of the support plate 7 away from the rubber plug seat 6.

[0035] By adopting the above technical solution, after the long bolt 10 is rotated away from the side vertical plate 5, the pull rod 8 can be held to pull the support plate 7 and the rubber plug seat 6 downward to disassemble them.

[0036] This utility model is an easily disassembled cleanroom embedded laminar flow hood. A top-mounting mechanism 3 is configured on the outside of the laminar flow hood body 1. When a hanging rod with a hook is installed on the cleanroom ceiling using expansion bolts, a sealing top strip 13 and a sealing gasket frame 14 can be respectively fastened and bonded to the upper and lower parts of the long frame support plate 4. Then, the long frame support plate 4 is fitted onto the outside of the laminar flow hood body 1, and the laminar flow hood body 1 is then hoisted at the hook using a lifting ring 2. Finally, by holding the pull rod 8, the rubber plug seat 6 above the support plate 7 is inserted between the side vertical plate 5, the long frame support plate 4, and the laminar flow hood body 1, using the long support bolt 1... 0 is screwed into the mounting holes 9 of the side vertical plate 5 and the rubber plug seat 6 to support the rubber plug seat 6; then the three sets of foot plates of the tripod side frame 11 are connected to the laminar flow hood body 1 by bolts. Then, a ceiling plate can be customized and installed near the laminar flow hood body 1 so that the ceiling plate can surround the side vertical plate 5, the rubber plug seat 6 and the laminar flow hood body 1, and expose the tail of the long support bolt 10 and the operating position of the laminar flow hood body 1 below the ceiling plate. At this time, the long frame support plate 4 presses the sealing gasket frame 14 on the ceiling plate for sealing and pressing, realizing the embedded installation of the laminar flow hood body 1.

[0037] When the laminar flow hood body 1 needs to be disassembled for maintenance, the long support bolt 10 can be unscrewed from the side hanging plate 5. At this time, hold the pull rod 8 and pull down to remove the rubber plug seat 6. Then, hold the tripod side frame 11 and the U-shaped support frame 12 and lift the laminar flow hood body 1 towards the side hanging plate 5 using a ladder or climbing machinery. After the lifting ring 2 is separated from the hook, the laminar flow hood body 1 can be lifted down and directly removed from the long frame support plate 4, thus facilitating the disassembly of the laminar flow hood body 1 in the clean room.
