Description

Technical Field

[0001] The utility model belongs to the technical field of smoke damper doors, in particular to a leakage-proof smoke damper door. Background Art

[0002] Power station boilers, also known as "power plant boilers", refer to medium and large boilers in power plants that provide a specified amount and quality of steam to steam turbines. Boilers are energy conversion equipment. The energy input to the boiler includes chemical energy and electrical energy in the fuel, and the boiler outputs steam, high-temperature water or organic heat carriers with a certain amount of thermal energy. The hot water or steam generated in the boiler can directly provide the required thermal energy for industrial production and people's lives, or it can be converted into mechanical energy through a steam power device, or the mechanical energy can be converted into electrical energy through a generator.

[0003] Boiler flue gas damper doors play a very important role in thermal power and chemical enterprises. Most of them need regular inspection and maintenance after use. At present, most flue gas damper doors use louvered damper doors. The louvered damper doors are sealed in the gap between the closed dampers, and the sealing effect is poor. There is still a certain gap between the two adjacent blades after closing, and the sealing is poor, which makes it easy for flue gas to penetrate. At the same time, it is inconvenient for staff to repair and maintain the flue gas damper doors, which reduces the service life of the equipment. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the prior art, the utility model provides a leakage-proof smoke damper door, which can effectively solve the problems of the prior art.

[0008] A limiting groove is provided on the inner wall of the baffle plate, and a blocking plate is clamped on the inner side of the limiting groove;

[0009] The blocking frame is fixed to the inner wall of the baffle door frame, and a sealing mechanism is provided on the side of the blocking frame close to the baffle plate.

[0010] Furthermore, a sealing ring is provided on the outer side of the baffle door frame, and the other end of the sealing ring is tightly fitted with the baffle plate.

[0011] Furthermore, the driving mechanism includes a servo motor, a driving gear and a linkage gear. The servo motor is fixed inside the connecting cavity, the driving gear is fixed at the output end of the servo motor, the linkage gear is meshed and connected to the lower end of the driving gear, and the linkage gear is fixed to the baffle plate.

[0012] Furthermore, a return spring is provided on the inner wall of the limiting groove, and the other end of the return spring is connected to the blocking plate.

[0013] Furthermore, the sealing mechanism includes a sealing groove and an electromagnet block. The sealing groove is opened on one side of the sealing frame, and the cross-section of the sealing groove is a triangular structure. The sealing groove is clamped with one side of the sealing plate. The electromagnet block is fixed inside the sealing frame and connected to the sealing plate.

[0014] Furthermore, a control component is provided at the lower end of the servo motor, and the control component is connected to the servo motor and the electromagnet block.

[0015] Furthermore, a sealing gasket is sleeved on the outer surface of the blocking plate, and the outer surface of the sealing gasket is tightly fitted with the baffle door frame.

[0016] The utility model has the following beneficial effects:
