Description

Technical Field

[0001] The utility model relates to the technical field of smoke exhaust fire dampers, in particular to a heat exchange structure and a smoke exhaust fire damper. Background Technique

[0002] A smoke exhaust fire damper is a fire-fighting component, generally installed on the pipeline of a mechanical smoke exhaust system, normally in an open state. When a fire occurs, it opens for smoke exhaust. When the smoke temperature in the smoke exhaust pipeline reaches 280 degrees, it closes and meets the requirements of smoke leakage and fire resistance integrity within a certain time, playing a role in isolating smoke and preventing fire. Main materials: carbon steel, galvanized sheet, stainless steel.

[0003] In the existing smoke exhaust fire damper, the internal smoke converges, resulting in too high temperature, making it difficult for the fan to effectively exchange heat and dredge, causing the smoke temperature in the smoke exhaust pipeline to quickly reach 280 degrees and close. Too much smoke and dust accumulate in the smoke exhaust pipeline, adhering to the inside of the smoke exhaust pipeline, and it is easy to corrode its interior when getting wet for a long time. Content of the Utility Model

[0004] The purpose of the utility model is to provide a heat exchange structure and a smoke exhaust fire damper to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A heat exchange structure and a smoke exhaust fire damper, including a smoke exhaust fire damper mounting plate, through bolts, an external box and a sealing component. The periphery of the smoke exhaust fire damper mounting plate is threadedly connected with through bolts. An external box is arranged at the welding position on the smoke exhaust fire damper mounting plate. The mounting position of the sealing component is provided with the smoke exhaust fire damper mounting plate and through bolts. It also includes,

[0007] A heat exchange unfolding component, installed on the external box;

[0008] A heat exchange installation component, arranged on the external box;

[0009] Among them, an internal sealing box is welded inside the external box. A control end is movably installed at the top of the external box. A connecting plate is fixedly connected to the rear end of the external box. The periphery of the connecting plate is threadedly penetrated with snap bolts. A heat exchange box is fixedly connected to the rear end of the connecting plate.

[0010] For the heat exchange structure and the smoke exhaust fire damper as described above: The internal sealing box is fixedly installed through the smoke exhaust fire damper mounting plate and through bolts on the external box.

[0011] For the heat exchange structure and the smoke exhaust fire damper as described above: The external box and the heat exchange box are connected and installed inside the smoke exhaust fire damper mounting plate and the connecting plate.

[0012] The heat exchange structure and the smoke exhaust fire damper as described above: The heat exchange expansion assembly includes a movable plate movably installed inside the heat exchange box. A flexible connection cover is movably installed inside the movable plate. A hydraulic cylinder is arranged at the driving part on the flexible connection cover. A lock bracket is movably installed at one end of the flexible connection cover.

[0013] The heat exchange structure and the smoke exhaust fire damper as described above: The lock bracket and the flexible connection cover are folded inside the heat exchange box by hydraulic drive of the hydraulic cylinder.

[0014] The heat exchange structure and the smoke exhaust fire damper as described above: The heat exchange installation assembly includes a card slot opened on the built-in sealed box, and a mounting block is fixedly connected inside the card slot.

[0015] The heat exchange structure and the smoke exhaust fire damper as described above: A movable plate is arranged at the movable part on the card slot and the mounting block.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows: When the smoke exhaust fire damper is in the open state, the flexible connection cover can be unfolded inside the heat exchange box and the external box for heat insulation and dust filtration. Driven by the hydraulic cylinder and the lock bracket, the flexible connection cover can reciprocally fold and move, and the flue gas in the smoke exhaust pipe can be compressed to the outside of the heat exchange box, preventing the flue gas from gathering inside the smoke exhaust fire damper and causing too high a temperature, facilitating the effective heat exchange and dredging of the fan, avoiding the rapid closing of the smoke exhaust pipe due to the flue gas temperature reaching 280 degrees, filtering the flue gas dust in the smoke exhaust pipe, preventing dust from adhering to the inside of the smoke exhaust pipe, and avoiding long-term damp corrosion of its interior.

[0017] Driven by the hydraulic cylinder and the lock bracket, the flexible connection cover makes reciprocating hydraulic sliding on the movable plate. The flexible connection cover can be hydraulically slid and unfolded inside the built-in sealed box for dust filtration. Driven by the hydraulic cylinder and the lock bracket, the flexible connection cover can compress the high-temperature air to the outside of the heat exchange box, preventing the flue gas from gathering inside the smoke exhaust fire damper and causing too high a temperature, and facilitating the effective heat exchange and dredging of the fan.
