Boiler explosion door and boiler thereof

Abstract

The embodiment of the invention discloses a boiler explosion door and a boiler thereof. According to the boiler explosion door and the boiler thereof, the impact force on a door frame when a door cover rotates and resets by a large margin is effectively reduced, and the door frame is protected from deformation. The boiler explosion door comprise the door frame, the door cover, a door spindle and at least two damping mechanisms. The door spindle is rotationally fixed on the door frame. The door cover is fixedly connected to the door spindle and rotates synchronously with the door spindle. The at least two damping mechanisms are installed on the periphery of the inner side of the door cover, each damping mechanism comprises a spring, a guide pipe, a first limiting rod and a second limiting rod, the bottom ends of the guide pipes are fixedly attached to the inner wall of the door cover, and the first limiting rods are fixed to the bottom ends of the guide pipes. The second limiting rods are installed at the top ends of the guide pipes and extend out of the guide pipes, the springs are installed between the first limiting rods and the second limiting rods in a penetrating mode, and gaps are formed between the first limiting rods and the second limiting rods.

Description

technical field [0001] The embodiment of the present application relates to the field of heating equipment, in particular to a boiler explosion-proof door and a boiler thereof. Background technique [0002] Boiler is a kind of heat conversion equipment. The energy input to the boiler is in the form of chemical energy in fuel, electric energy, heat energy of high-temperature flue gas, etc. After conversion by the boiler, it outputs steam, high-temperature water or organic heat carrier with certain heat energy. . At present, during the use of most boilers, explosions often occur due to various reasons, ranging from damage to the main body of the boiler, to causing personal casualties, and easily causing large economic losses. [0003] Gravity inclined explosion-proof door is a widely used type with simple structure, convenient manufacture, flexible take-off, automatic reset and good safety. It does not affect the operation of the boiler when it is started, and it will be open...

AI Technical Summary

Problems solved by technology

Due to the weight and angle of the gravity inclined explosion-proof door, in the actual operation of the explosion-proof door, the ordinary gravity-type explosion-proof door is just a simple base and cover plate. The explosion-proof door with such a structure is easy to be damaged by the excessive internal pressure of the boiler when it is used. When the cover is rotated and reset by a large scale, the impact force on the door frame is very large, resulting in the deformation of the door frame of the explosion-proof door, the closure is not tight, and the service life of the explosion-proof door is reduced.
