Description

Technical Field

[0001] This utility model belongs to the field of cleanroom filtration duct technology, and in particular relates to an integrated connection structure of purification panel and duct. Background Technology

[0002] Cleanroom ducts are specialized pipes used in cleanroom air conditioning systems. They are made of special materials such as cleanroom duct purification panels and possess characteristics such as high sealing performance, smooth inner walls (not easy to accumulate dust), corrosion resistance, and pollution prevention. Their core function is to transport clean air that has been filtered through high-efficiency filters and precisely controlled in temperature and humidity without pollution or leakage, in order to maintain the positive / negative pressure and air cleanliness level (such as ISO Class) required by the cleanroom.

[0003] Cleanroom ductwork panels are specialized sheet materials used in the manufacture of cleanroom ducts. They are typically made of galvanized steel, stainless steel, or aluminum, with a specially treated surface (such as an antibacterial coating or film). These panels possess core characteristics such as high cleanliness, high sealing performance, smooth and easy cleaning, dust resistance, antibacterial properties, corrosion resistance, and high strength. This ensures that the ductwork system itself does not generate pollution, accumulate dust, or leak, effectively maintaining the cleanliness of the transported air.

[0004] However, the air duct formed by the purification panel can only play the role of antibacterial and dust-free on the inner surface of the channel. The air intake duct is directly connected to the external ambient air, which contains some light garbage. If it is not filtered, it will affect the normal use of the clean room and increase the maintenance frequency. However, it is obviously very expensive to use an independent air filtration system.

[0005] To address the aforementioned issues, this application proposes an integrated connection structure between the purification panel and the air duct. Utility Model Content

[0006] The purpose of this utility model is to provide an integrated connection structure between the purification panel and the air duct, which solves the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model is an integrated connection structure of a purification panel and an air duct, including an air duct body composed of purification panels. A maintenance port is provided at the lower end of the air duct body. A No. 1 plate is hinged to the lower end of the air duct body. A filter screen is installed on the No. 1 plate. The filter screen is installed in the air duct body through the No. 1 plate. A No. 2 plate is hinged to the No. 1 plate. The No. 2 plate is close to the air inlet end of the air duct body. The filter screen is pressed and fixed in the air duct body by a pressure frame on the No. 2 plate. When the No. 1 plate and the No. 2 plate are closed at the same time, they cover the maintenance port.

[0009] Furthermore, an installation frame is fixed inside the duct body, and a partially embedded sealing gasket is provided at one end of the installation frame near the filter screen. The other end of the sealing gasket is pressed into contact with the connecting frame outside the filter screen.

[0010] Furthermore, a socket is formed at the end of the first plate away from the hinged end with the air duct body, and a plug plate is formed at the lower end of the connecting frame to be inserted and connected to the socket.

[0011] Furthermore, a vertical pressure frame is fixed to the inner side of the second plate to press the connecting frame and the sealing gasket together, and a support rod is also supported between the pressure frame and the second plate.

[0012] Furthermore, a No. 1 through hole is provided at the end of the No. 1 plate away from the hinge, and a No. 1 threaded hole adapted to the No. 1 through hole is provided on the air duct body.

[0013] Furthermore, the second plate has a second through hole at the end away from the hinged end with the first plate, and the air duct body has a second threaded hole adapted to the support rod.

[0014] Furthermore, a positioning groove is provided on the side of the plug plate, and a spring piece is installed inside the socket to elastically engage with the positioning groove.

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

[0016] This utility model features a reversible filter screen installed inside the duct body via a No. 1 plate. After the filter screen is flipped, it can be directly removed from inside the duct body without the need for bolts to fix it inside the duct body, greatly improving the ease of installation and disassembly.

[0017] This invention features a hinged second plate on the first plate, which can be opened independently to clean the end of the filter screen near the air intake without disassembling the filter screen, thus improving the convenience of filter screen maintenance.

Detailed Implementation

[0027] 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 scope of protection of the present utility model.

[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0029] Please see Figures 1-5As shown, this utility model is an integrated connection structure of a purification panel and an air duct, including an air duct body 1 composed of a purification panel. A maintenance port 11 is provided at the lower end of the air duct body 1. A first plate 3 is hinged to the lower end of the air duct body 1. A filter screen 2 is installed on the first plate 3. The filter screen 2 is installed in the air duct body 1 through the first plate 3. A second plate 4 is hinged to the first plate 3. The second plate 4 is close to the air inlet end of the air duct body 1. The filter screen 2 is pressed and fixed in the air duct body 1 by the pressure frame 41 on the second plate 4. When the first plate 3 and the second plate 4 are closed at the same time, they cover the maintenance port 11. In this embodiment, the maintenance port 11 takes into account the maintenance and disassembly of the filter screen 2, and at the same time forms a rotation space for the filter screen 2 to follow the first plate 3 to ensure flexibility.

[0030] Specifically, an installation frame 12 is fixed inside the duct body 1. A partially embedded sealing gasket 121 is provided at one end of the installation frame 12 near the filter screen 2. The other end of the sealing gasket 121 is pressed into contact with the connecting frame 21 outside the filter screen 2. A vertical pressure frame 41 is fixed inside the second plate 4 to press the connecting frame 21 and the sealing gasket 121 together. A support rod 42 is also supported between the pressure frame 41 and the second plate 4. The rotation of the second plate 4 is used to press the filter screen 2 and the sealing gasket 121 together through the pressure frame 41, thereby realizing the boltless connection of the filter screen 2, which takes into account both operation convenience and sealing reliability.

[0031] Furthermore, a socket 31 is formed at the end of the first plate 3 away from the hinged end of the air duct body 1, and an insert plate 211 is formed at the lower end of the connecting frame 21 to be inserted and connected to the socket 31. Furthermore, a positioning groove 2111 is provided on the side of the insert plate 211, and a spring piece 311 is installed inside the socket 31 to elastically engage with the positioning groove 2111. In this embodiment, after the spring piece 311 and the positioning groove 2111 cooperate, they can prevent the filter screen 2 from detaching from the connecting frame 21 under the action of external force, thus playing a pre-positioning role. At the same time, when the first plate 3 is closed, the top of the filter screen 2 contacts the air duct body 1, which also forms an anti-detachment structure, taking into account both convenient operation and reliable connection.

[0032] Specifically, a through hole 32 is provided at the end of the first plate 3 away from the hinge, and a threaded hole 13 adapted to the through hole 32 is provided on the duct body 1. In order to enhance the sealing between the first plate 3 and the duct body 1, a sealing gasket can be provided at the contact position between the two. After the bolt passes through the through hole 32, it is threadedly connected to the threaded hole 13, thereby pressing the second plate 4 tightly against the duct body 1.

[0033] Specifically, the end of the second plate 4 away from the hinged end with the first plate 3 has a second through hole 43, and the air duct body 1 has a second threaded hole 14 that matches the support rod 42. In order to enhance the sealing between the second plate 4 and the air duct body 1, a sealing gasket can be set at the contact position between the two. After the bolt passes through the second through hole 43, it is threadedly connected to the second threaded hole 14, thereby pressing the second plate 4 tightly against the air duct body 1.

[0034] It is understandable that this utility model has a flip-up filter screen installed in the duct body through a No. 1 plate. After flipping, it can be directly removed, eliminating the need for bolt fixing and significantly improving the convenience of installation and disassembly. At the same time, by setting an openable No. 2 plate on the No. 1 plate, the air intake end can be cleaned without removing the filter screen, improving the convenience of maintenance.

[0035] One specific application of this embodiment is as follows: Figure 1-2 The diagram shows the connection status of the duct body 1 and the filter screen 2;

[0036] To maintain the air inlet surface of filter 2: Remove the bolt connecting the second through hole 43 and the second threaded hole 14, and open the second plate 4 downwards along the hinge with the first plate 3, which is the attached... Figure 3 As shown in the diagram, hands and external cleaning tools can directly enter the duct body 1 and come into contact with the filter screen 2. After maintenance, close the second plate 4 and tighten it with bolts.

[0037] To replace filter 2: Remove all bolts connecting plate 3 and plate 4 to duct body 1. Then, using the hinge between plate 3 and duct body 1, simultaneously rotate filter 2, plate 3, and plate 4 downwards to open the filter. Figure 4 In the state shown, remove filter 2 from plate 3 and replace it. After replacing the filter 2, insert plate 211 and socket 31, so that positioning groove 2111 is locked by spring piece 311. Filter 2 is pre-positioned on plate 3. Then, rotate plate 3 and filter 2 upwards to connect with duct body 1. Plate 3 is attached to the lower end of duct body 1. One end of filter 2 contacts sealing gasket 121. Tighten the bolts on plate 3. Then rotate plate 4 upwards. Press frame 41 pushes filter 2 and presses it with sealing gasket 121 to form a seal between connecting frame 21 and duct body 1. Tighten and fix plate 4 to duct body 1 with bolts.
