Description

Technical Field

[0001] This utility model belongs to the field of roller shutter technology, and more specifically, relates to a fireproof roller shutter for clean rooms. Background Technology

[0002] With the country's large-scale infrastructure construction (such as subways, airport expansion and renovation, and cleanrooms), the demand for roller shutters used in buildings is increasing, and the performance requirements are becoming more stringent. In these critical locations, the fire safety alert levels are also becoming increasingly stringent.

[0003] Cleanrooms, also known as dust-free workshops, clean rooms, or sterile spaces, are spaces where airborne particles, harmful gases, bacteria, and other contaminants are eliminated. They maintain controlled temperature, pressure, airflow speed, airflow distribution, noise and vibration, lighting, and static electricity within specific requirements. When external air conditions change, the cleanroom maintains its pre-set cleanliness, temperature, humidity, and pressure. However, in the event of a fire outdoors, staff inside often cannot detect it promptly. If the fire is large, staff cannot easily approach the roller shutters, which cannot be deployed in time, thus failing to protect the interior. Furthermore, traditional fire-resistant roller shutters are mostly single-layer structures, and their fire resistance needs improvement.

[0004] Traditional roller shutters in the current technology have a rigid contact between the bottom plate and the ground, which leaves gaps. The fireproof and smoke-proof effects need to be improved. At the same time, it cannot be guaranteed that the fireproof roller shutter can be completely sealed when closed to prevent outside air, dust or other pollutants from entering the clean room. Utility Model Content

[0005] Therefore, in order to solve the above-mentioned technical problems, this utility model proposes a fireproof roller shutter for cleanrooms, including a roller shutter 10, a roller shaft 20, a roller door motor 30, a roller shutter box 40, a guide rail 50, a control box 60, and a switch button 70. The roller shaft 20 and the roller door motor 30 are placed inside the roller shutter box 40. The roller shaft 20 is placed horizontally and supported at both ends in the roller shutter box 40. The roller shaft 20 is connected to the roller door motor 30. The top end of the guide rail 50 is connected to the roller shutter box 40. The guide rail 50 is placed on both sides of the roller shutter 10. The bottom end of the guide rail 50 is connected to a channel steel 80, which is connected to the wall to fix the stability of the guide rail 50. One end of the roller shutter 10 is connected to the roller shaft 20. The roller shutter 10 rotates around the central axis of the roller shaft 20 to open and close. The two sides of the roller shutter 10 are connected to the corresponding roller shaft 20. The guide rail 50 is slidably connected. The control box 60 and the switch button 70 are located outside the roller shutter box 40. The roller shutter 10 has two layers, which are parallel and spaced apart. The roller shaft 20 connected to each layer of roller shutter 10 is parallel. The roller door motor 30 is located on the same side of the two roller shafts 20 and drives the two roller shafts 20 to rotate in the same direction. Each roller shutter 10 is slidably connected to its corresponding guide rail 50. The switch button 70 controls the rotation of the roller door motor 30, which drives the two roller shafts 20 to rotate synchronously. This allows the two layers of roller shutter 10 to be either pulled up and in an open state or unfolded downwards and in a closed state, thereby ensuring the airtightness of the clean room, preventing external air, dust or other pollutants from entering the clean room, protecting the high cleanliness of the clean room, and also improving fire resistance.

[0006] A fireproof roller shutter for cleanrooms includes a roller shutter 10, a roller shaft 20, a roller door motor 30, a roller shutter box 40, a guide rail 50, a control box 60, and a switch button 70. The roller shaft 20 and the roller door motor 30 are housed within the roller shutter box 40. The roller shaft 20 is horizontally positioned with both ends supported within the roller shutter box 40. The roller shaft 20 is connected to the roller door motor 30. The top end of the guide rail 50 communicates with the roller shutter box 40, and the guide rail 50 is positioned on both sides of the roller shutter 10. A channel steel 80 is connected to the bottom end of the guide rail 50, and the channel steel 80 is connected to the wall to ensure the stability of the guide rail 50. One end of the roller shutter 10 is connected to the roller shaft 20. The roller shutter 10 rotates around the central axis of the roller shaft 20 to open and close vertically. The two sides of the roller shutter 10 are slidably connected to the corresponding guide rails 50. The control box 60 and the switch button 70 are located outside the roller shutter box 40. The roller shutter 10 has two layers, and the two layers of roller shutter 10 are arranged parallel to each other and spaced apart. The roller shaft 20 connected to each layer of roller shutter 10 is arranged parallel to each other. The roller door motor 30 is located on the same side of the two roller shafts 20 and drives the two roller shafts 20 to rotate in the same direction. Each roller shutter 10 is slidably connected to its corresponding guide rail 50. The roller door motor 30 is controlled to rotate by the switch button 70, which drives the two roller shafts 20 to rotate synchronously. This allows the two layers of roller shutter 10 to be pulled up and in an open state or unfolded downwards and in a closed state, thereby ensuring the airtightness of the clean room.

[0007] Furthermore, the roller blind 10 is made of silicone-coated fiberglass cloth.

[0008] Furthermore, a sealing strip 90 is provided at the connection between the guide rail 50 and the roller shutter box 40 for auxiliary sealing.

[0009] Furthermore, a sealing gasket 100 is provided at the point where the roller shutter 10 contacts the ground to assist in sealing, ensuring that the roller shutter 10 can be completely sealed when closed, preventing external air, dust or other pollutants from entering the clean room.

[0010] Furthermore, the sealing strip 90 and the sealing gasket 100 are made of silicone or rubber, which have good elasticity and strong sealing performance.

[0011] Furthermore, the outer side of the roller shutter box 40 is also provided with a color steel plate 110, and a hollow cavity is formed by multiple color steel plates 110 and walls. The roller shutter box 40 is placed in the hollow cavity to ensure the airtightness of the clean room.

[0012] Furthermore, one end of the color steel plate 110 is connected to the roof beam, and the other end of the color steel plate 110 is connected to the guide rail 50. Both connections are sealed with sealant. A connecting rod 120 is provided in the hollow cavity formed by the multiple color steel plates 110 and the wall. One end of the connecting rod 120 is fixedly connected to the roof beam, and the other end is connected to the color steel plate 110 to fix the color steel plate 110 and prevent it from falling.

[0013] Furthermore, an angle steel 130 is provided at the connection between the channel steel 80 and the wall. One end of the angle steel 130 is welded to the channel steel 80, and the other end of the angle steel 130 is connected to the wall. The angle steel 130 is used to enhance the stability of the channel steel 80 and prevent it from swaying left and right.

[0014] Furthermore, both the channel steel 80 and the angle steel 130 are made of aluminum alloy, making them lightweight and easy to handle.
