Combustion furnace with full-automatic feed and heath fuel feed device

Abstract

The invention belongs to the fuel supply of fuel equipment and in particular relates to a combustion furnace with full-automatic feed and a hearth fuel feed device, and a fuel can be combusted from top to bottom in the combustion furnace. The hearth fuel feed device provided by the invention comprises a rectilinear translation bedplate, a feed barrel, a translation device, a feed device and a control device, wherein the translation device comprises a translation motor, a translation variator, a translation position switch, a connecting device and a rectilinear and rotary translation device; the feed device comprises a fuel pallet hoisting mechanism, a feed motor, a feed variator, a feed position switch. a connecting device and a rectilinear and rotary translation feed device; and the control device comprises a translation position switch and a feed position switch control circuit. The combustion furnace provided by the invention comprises a burner part, a furnace body part and the hearth fuel feed device. According to the invention, a moving supply and propulsion feed mode is adopted and continuous and uninterrupted addition of the fuel is realized through circulated supply and continuous propulsion, thereby meeting continuous and long-time requirements for applying fire.

Description

technical field [0001] The invention belongs to household furnaces or stoves with solid fuels, and relates to a fully automatic feeding combustion furnace and a furnace fuel feeding device in which fuel is burned from top to bottom. Background technique [0002] Combustion devices in which the fuel is burned from top to bottom have been used to a certain extent in vast rural areas, achieving a certain energy-saving effect. But because most of the fuel in the existing type furnace adopts one-time addition, the method of re-adding and re-igniting after burning, as the patent application number is CN200610018486.7, and the title of invention is "two-way blast organic fuel furnace secondary combustion Method and special energy-saving furnace", this feeding method is mainly limited by the way the fuel burns from top to bottom and the furnace is a closed structure, so it is only suitable for household use; it cannot meet the continuous long-term fire demand , even if the problems...

But because most of the fuel in the existing type furnace adopts one-time addition, the method of re-adding and re-igniting after burning, as the patent application number is CN200610018486.7, and the title of invention is "two-way blast organic fuel furnace secondary combustion Method and special energy-saving furnace", this feeding method is mainly limited by the way the fuel burns from top to bottom and the furnace is a closed structure, so it is only suitable for household use; it cannot meet the continuous long-term fire demand , even if the problems such as soot emission are solved, it cannot enter large users such as canteens and hotels, and the energy-saving effect cannot be exerted to a greater extent; existing feeding devices such as "closed biomass fuel feeding device", patent No. : CN200820185125.6, the upper end of the screw device is provided with a flap door device that communicates with the screw device, the flap door device is provided with a feed port for fuel, and the lower end of the screw device communicates with a metering silo. Equipped with a fuel level detection device, although it can realize continuous and uninterrupted fuel addition, but its screw device is prone to mechanical failures such as jamming, which seriously affects the use efficiency

This shows that the prior art scheme is also difficult to meet people's actual needs
