Boiler capable of preventing vent holes from being blocked

Abstract

The invention relates to a boiler capable of preventing vent holes from being blocked. The boiler comprises a main body, a bottom plate, an air blowing mechanism and a dredging mechanism, the bottom plate is arranged in the main body, the air blowing mechanism is arranged below the bottom plate, the dredging mechanism is arranged in the main body, the dredging mechanism comprises a driving assembly, a pulling assembly and a dredging assembly, and the air blowing mechanism comprises a fan, an air blowing pipe and a nozzle. According to the boiler capable of preventing the vent holes from being blocked, air blowing is achieved through the air blowing mechanism, dredging of the vent holes is achieved through the dredging mechanism, online dredging of the vent holes is achieved through linkage of the dredging mechanism and the air blowing mechanism, a pure mechanical structure is adopted in linkage, the stability of the device is improved, the service life of the device is prolonged, meanwhile, air blown out by the fan serves as a driving source of the dredging mechanism, driving sources such as a motor are not needed for driving, energy is saved, a pull rope is evenly wound around a wire coil through a winding assembly, winding and knotting of the pull rope are avoided, the device runs more stably, and practicability is improved.

Description

technical field [0001] The invention relates to a boiler which prevents clogging of vent holes. 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. 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. Furnace refers to the place where fuel is burned. The boiler includes two parts: the boiler 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 regenerated. The generator converts mechanical energy into electrical energy, and the boiler that provides hot water is called a hot water boiler. It is mainly used in daily life and has a small amou...

Problems solved by technology

[0003] Most of the existing boilers still mainly burn coal. During the combustion of coal, air is generally blown in by a fan to increase the oxygen content and make the coal burn more fully. However, coal will produce coal ash after burning. Coal ash is easy to block the ventilation holes, causing air to be unable to enter the coal, thereby affecting the combustion effect of the coal. Therefore, after the device has been used for a period of time, it is generally necessary to manually dredge the ventilation holes, which consumes a lot of manpower. Therefore, there are ventilation holes on the market. Boilers with automatic air hole dredging function, and when the dredging device of this kind of boiler is used, it generally needs a driving source such as a motor to drive, and the energy consumption is relatively large
