Fume exhaust device for combustion boiler facilitating removal of dirt on inner wall

Abstract

The invention discloses a fume exhaust device for a combustion boiler facilitating removal of dirt on inner wall. The fume exhaust device for the combustion boiler comprises a bottom plate, a fume exhaust cylinder is fixed to the outer wall of the top of the bottom plate by bolts, and a heat insulation sleeve with specifications adaptive to specifications of the fume exhaust cylinder is fixed to the outer wall of one side of the fume exhaust cylinder by bolts. A horizontally placed transverse plate is welded to the outer wall of one side of the fume exhaust cylinder, a motor is fixed to the outer wall of the top of the transverse plate by bolts, a first bevel gear is welded to the outer wall of one side of an output shaft of the motor, a groove is formed in the outer wall of one side of the fume exhaust cylinder, a bearing is welded in the groove, and a connecting shaft is welded to the inner wall of the bearing. The motor of the fume exhaust device works to drive the gears to mesh, sothat a spiral scraper rotates to remove the dirt attached to the inside of the fume exhaust cylinder, the impurity removal capability of the device is improved, part of impurity particles in flue gasis filtered and separated, and is discharged from an access opening, and the convenience of impurity removing of the device is improved.

Description

technical field [0001] The invention relates to the technical field of combustion boilers, in particular to a smoke exhaust device for a combustion boiler which is convenient for removing dirt on the inner wall. Background technique [0002] The boiler is a kind of energy conversion equipment. The energy input to the boiler includes chemical energy and electric energy in the fuel, and the boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of heat energy. The original meaning of the pot refers to the water container heated on the fire, and the furnace refers to the place where fuel is burned. The boiler includes two parts: the pot and the furnace. The hot water or steam generated in the boiler can directly provide the required heat energy for industrial production and people's life, and can also be converted into mechanical energy through a steam power device, or converted into electrical energy through a generator. Boilers that provid...

Problems solved by technology

[0003] Some boiler devices currently on the market have more or less deficiencies. After long-term use of the smoke exhaust pipe, it is inconvenient to clean the dirt on the inner wall and to discharge impurities. In order to solve the above problems, this new model proposes a new smoke exhaust device.
