Abstract

A fire-adjustable commercial firewood stove mainly comprises a shell, a bottom, a door frame, a heat-insulating refractory material, a smoke pipe, an ash discharge pipe, a fire adjusting plate, an ash bucket and an induced draft fan, wherein the induced draft fan is communicated with the atmosphere through a connecting pipe, a mixing box, a pipe, a negative pressure chamber and a hole; the draught fan is communicated with the atmosphere through a connecting pipe, a mixing box, a smoke pipe, a hearth, an ash discharging pipe and a firepower adjusting plate. The fire power of the utility model is adjustable, namely the fire power adjusting plate is completely closed, dense smoke in the hearth can not spread indoors through the door and the stove grate, and no smoke exists indoors. The utility model has simple operation, strong fuel adaptability and wide market prospect.

Description

Firepower-adjustable commercial firewood stove

Technical Field

The utility model relates to the technical field of biomass gasification combustion, in particular to a firepower-adjustable commercial firewood stove.

Background

The firewood stove is also called a biomass cooking stove, a plant cooking stove and an energy-saving firewood stove. The firewood stove uses wood blocks, wood sections, branches, straws, sawdust, leaves and biomass molding particles as fuel, and uses a corresponding stove structure to enable the fuel to be polymerized at a stove mouth by the heat energy of wood direct combustion and wood gasification combustion so as to carry out cooking work. At present, the firewood kitchen that restaurant commonly used is called the pan pot platform, and its firepower adjusting device reaches the purpose of firepower regulation in tobacco pipe position, namely through changing the degree of blocking of tobacco pipe, the shortcoming of doing so is: when the smoke pipe is completely blocked, the dense smoke in the range can rapidly spread into the room through the door and the range grate.

Disclosure of Invention

The utility model aims to provide a firepower-adjustable commercial firewood stove which has long service life, is indoor smokeless, can be moved and is convenient to manufacture.

The technical scheme adopted by the utility model for solving the technical problems is as follows: the utility model provides an adjustable commercial firewood kitchen of firepower, by shell, end, door frame, thermal-insulated refractory material, tobacco pipe, ash pipe, firepower regulating plate, ash bucket, the draught fan is constituteed, characterized by: the protective cover, the connecting plate and the partition plate together enclose a negative pressure chamber; the induced draft fan is communicated with the atmosphere through a connecting pipe, a mixing box, a pipe, a negative pressure chamber and a hole; an ash discharging pipe is fixedly arranged on the bottom, a firepower adjusting plate is arranged at the lower end of the ash discharging pipe, and a stove grate is arranged at the upper end of the ash discharging pipe; the draught fan is communicated with the atmosphere through a connecting pipe, a mixing box, a smoke pipe, a hearth, a stove grate, an ash discharging pipe, a firepower adjusting plate and a gap of the ash discharging pipe.

Compared with the prior art, the utility model has the following advantages:

1. the utility model has long service life, can move, can adjust the fire power, namely completely close the fire power adjusting plate, and the dense smoke in the hearth can not spread indoors through the door and the stove grate, so the utility model has no smoke indoors.

2. The utility model has simple production process and good practical effect. Can be used for large-scale industrial production and has wide market prospect.
