Description

Technical Field

[0001] The utility model relates to the technical field of fire dampers, in particular to a fire damper with a dust-proof structure. Background Art

[0002] Fire damper is a kind of temperature control of memory alloy, which uses gravity and spring mechanism to close the valve. Some new products use memory alloy to produce deformation to close the valve. When the smoke temperature reaches 280℃, people have basically been evacuated and smoke exhaust is meaningless. At this time, the smoke is already carrying fire, and the valve automatically closes to prevent the fire from spreading.

[0003] Since the fire damper needs to be manually reset by the user, and after the fire damper is automatically closed, a large amount of dust in the smoke accumulates at the fire damper, which hinders the reset of the fire damper and brings difficulties to the user's reset operation, while the fire damper is in the open state.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 A fire damper with a dustproof structure comprises a valve body 1 and a dust storage box 2 arranged directly below the valve body 1. An observation port is arranged on the outer wall of the dust storage box 2. A transparent glass 12 made of explosion-proof material is fixedly embedded in the observation port, which is used to cooperate with the observation port to facilitate users to understand the dust storage amount. A fixing mechanism is arranged between the dust storage box 2 and the valve body 1. The fixing mechanism comprises a plurality of fixing rods 8 fixed at the lower end of the valve body 1, which are used to fix the dust storage box 2. The lower end of the fixing rod 8 is fixedly connected to the upper end of the dust storage box 2. The two ends of the valve body 1 are respectively an air inlet and an air outlet;

[0022] In this embodiment, a V-shaped groove is provided at the bottom of the valve body 1 and near the air inlet, and a metal mesh 3 is fixedly embedded in the V-shaped groove to prevent larger debris from falling into and causing clogging of the connecting pipe 4. An opening communicating with the V-shaped groove is provided at the lower end of the valve body 1, and a connecting pipe 4 communicating with the opening is fixedly connected to the lower end of the valve body 1 for circulating dust, and the lower end of the connecting pipe 4 is fixedly connected to the upper end of the dust storage box 2;

[0023] In this embodiment, a cleaning port communicating with the interior of the dust storage box 2 is provided on the outer wall of the dust storage box 2, and a closing mechanism corresponding to the cleaning port is provided on the outer wall of the dust storage box 2. The closing mechanism includes a cover plate 11 rotatably connected to the outer wall of the dust storage box 2 corresponding to the cleaning port, and is used to close the cleaning port. A bolt 10 is inserted on the side of the cover plate 11 away from the dust storage box 2, and is used to fix the cover plate 11. The cover plate 11 is fixed to the dust storage box 2 by the bolt 10;

[0024] In this embodiment, a cleaning mechanism is provided in the dust storage box 2, which includes a scraper 5 slidably connected to the bottom of the dust storage box 2 for scraping out dust. Two guide rods 7 are slidably inserted in the scraper 5 for keeping the scraper 5 moving in a straight line. The two ends of the guide rods 7 respectively penetrate the scraper 5 and are fixedly connected to the left and right sides of the dust storage box 2. A pull rod 6 is fixedly connected to the outer wall of the scraper 5 for driving the scraper 5 to move. One end of the pull rod 6 away from the scraper 5 extends into the cleaning port. One end of the pull rod 6 away from the scraper 5 is fixedly connected to a pull ring 9 for facilitating the user to pull the pull rod 6.

[0025] In this embodiment, during use, after the valve body 1 is automatically closed, dust will accumulate at the air inlet of the valve body 1. At this time, affected by the closing of the valve body 1, the dust falls into the V-shaped groove and then enters the dust box 2 through the opening and the connecting pipe 4, thereby preventing dust accumulation from affecting the subsequent resetting operation of the valve body 1. When it is necessary to clean the dust in the dust box 2, the bolt 10 is manually unscrewed, the cover 11 is manually opened, and the dust is discharged through the cleaning port. At the same time, the pull ring 9 is manually pulled to drive the pull rod 6 to move, and the scraper 5 is driven to move by the pull rod 6, and the dust in the dust box 2 is scraped out by the scraper 5, thereby improving the cleaning efficiency.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
