Description

a heating stove

technical field

The utility model belongs to the field of heating equipment, in particular to a heating furnace.

Background technique

Heating stoves are common heating equipment, mainly including return air stoves, biomass pellet heating stoves, electric stoves, etc. Among them, heating stoves that need to use solid fuels such as coal and biomass pellets for combustion are widely used because of their large thermal power and wide thermal coverage. This type of heating furnace includes furnace surface, furnace body, furnace core, base, ash removal device and ash box, etc. The furnace core is the core component of the heating furnace; the current furnace core is mainly a core body that runs through the axis direction. When in use, the furnace core is placed in the furnace body until the bottom of the furnace is in contact with the ash removal device on the base; then the fuel is put into the core and ignited, and the fuel provides oxygen for the combustion of the fuel through the air inlet set on the furnace body. This method realizes the continuous combustion of the fuel, but because the air flow transmitted by the air inlet accumulates at the bottom of the core, the air flow is almost exhausted at the bottom of the core, and the fuel has not been completely burned at this time, so it will lead to a large amount of Smoke is generated and the fuel is not fully burned, resulting in a waste of fuel resources. In addition, since the fuel is mainly burned at the bottom of the core, the flame generated at the top of the core is very small, so that the temperature of the stove surface rises slowly, and it is not conducive to daily operations such as cooking food.

In response to this problem, the applicant has further improved the furnace core to increase the strength of the flame at the top of the core body, reduce the amount of fuel used, and further reduce the waste of fuel.

Utility model content

The purpose of the utility model is to provide a heating furnace to solve the problem that the heating furnace in the prior art requires a large amount of burning fuel to quickly heat up the furnace surface.

A heating furnace in this scheme includes a base, an ash box, an ash removal device, a furnace body, a furnace core and a furnace surface; the ash box and the ash removal device are arranged in the base, and the furnace body is fixedly connected to the base , the furnace body is provided with an air inlet; the furnace surface is fixedly connected to the furnace body, the furnace core is located in the furnace body and is placed on the ash removal device; It is located between the furnace body and the furnace core; the furnace core includes a core body that penetrates in the axial direction, the wall of the core body is provided with a plurality of ventilation holes that communicate with the inside of the core body, and the ventilation holes are located in the upper half of the core body. .

The working principle of this scheme and its beneficial effects: when in use, the fuel is placed in the furnace core and ignited; the fuel is burned at the bottom of the furnace core, and the degree of combustion of the fuel can be controlled by controlling the size of the opening of the air inlet. The incompletely burned fuel forms mixed combustible gas and rises rapidly to the upper half of the furnace core; due to the supplementary air hole on the base, the supplementary air hole is located between the furnace body and the furnace core; the outside air will be supplied from the supplementary air on the base The hole enters the furnace body. Due to the combustion of the fuel inside the furnace core, the temperature of the air in the furnace body is high, and a large amount of external air enters the furnace body; The gas supplements oxygen to promote the secondary combustion of the unburned mixed combustible gas. Since the fuel in the upper half of the core is relatively close to the furnace surface when burning, the flame generated by it can directly act on the furnace surface, which promotes the rapid increase of the furnace surface temperature. Therefore, the heating furnace in this solution can also achieve a rapid increase in the temperature of the furnace surface under the condition of using less fuel, which greatly reduces the waste of fuel.

Further, the ash removal device includes a tie rod and a ash removal plate, and one end of the tie rod is fixedly connected to the ash removal board; the ash removal board is provided with a ash leakage hole, and the bottom of the ash removal board is slidably connected with a closed ash leakage hole The end of the pulling rod away from the ash removal board penetrates the base and extends to the outside of the base; the ash removal board is located just above the ash box; the base is provided with a support plate for supporting the ash retention board. The ash removal device in the prior art generally uses a furnace bridge. When the furnace bridge removes ash, the fuel easily falls into the ash box from the gap of the furnace bridge; and the fuel is easily broken when the furnace bridge is pulled, so that the fuel is easily broken. further fuel consumption. By setting the ash removal plate, the ash blocking plate and the ash leakage hole; when the ash generated by the combustion of the fuel fills the ash leakage hole on the ash removal plate, the pull rod pulls the ash removal plate, at this time, the ash located in the ash leakage hole The material is pulled and separated from the furnace core; and the space left by the ash leakage hole is filled by the upper surface of the ash removal board, and the upper surface of the filling part of the ash removal board supports the fuel to continue to burn. When the ash leakage hole is pulled away from the ash baffle, the ash that loses the support of the ash baffle will fall into the ash box below. After the ash material falls into the ash box, the ash removal plate is pushed by the pull rod until the ash leakage hole is located directly under the furnace core; during this process, the ash baffle plate re-supports the ash material, so that it can be used continuously.

Further, a feeding hopper is detachably connected to the outer wall of the core body, and the feeding hopper communicates with the core body. The setting of the feeding hopper makes the feeding process to the core more convenient.

During the combustion process of the furnace core, the bottom of the core body is connected with an air supply device and an igniter, and at the same time, it is heated more; the lower half of the core body is easily worn out, thereby reducing the overall service life of the core body. The core body and the combustion plate are used to form the furnace core, so that the combustion plate is heated more, and can be replaced in time when it is damaged, thereby improving the service life of the core body and reducing the overall consumption of the furnace core.

Further, a ventilation cavity is sleeved on the combustion disc, the wall of the ventilation cavity is provided with installation holes for the air supply device and the igniter to pass through, and the combustion disc is also provided with a plurality of air adjustment holes.

In the combustion plate, oxygen is supplemented at multiple positions of the combustion plate, which is beneficial to the balanced combustion of the fuel in the combustion plate.

Further, the air supply device is a fan, the igniter includes a ventilation pipe, a heating device and an air inlet cavity, one end of the ventilation pipe is connected to the heating device, and an air duct is connected to the ventilation pipe; the fan is connected to the One end of the air inlet cavity, and one end of the air guide pipe away from the ventilation pipe is located in the air inlet cavity. In use, the end of the ventilation pipe away from the heating device and the end of the air inlet cavity away from the fan are connected to the core of the fuel heating furnace. Put the fuel into the core, start the fan and the heating device, the air flow generated by the fan is divided into two parts and enter the air inlet cavity and the air duct. The hot air enters the core from the ventilation duct to ignite the fuel. After the fuel is ignited, the heating device is turned off, and the cold air generated by the rear fan continues to provide oxygen for the fuel through the air inlet cavity and the ventilation pipe. During the fuel combustion process, because the cold air continuously passes through the ventilation pipe, the influence of the heat generated by fuel combustion on the ventilation pipe is greatly reduced, thereby improving the service life of the ventilation pipe and the heating device.

Further, both the air guide pipe and the ventilation pipe are located in the air inlet cavity. Both the air guide pipe and the ventilation pipe are arranged in the air inlet cavity, which helps to reduce the overall structure of the igniter. More importantly, after setting the air guide pipe and the ventilation pipe in the air inlet cavity, the two occupy a lot of space in the air inlet cavity, which makes the air flow speed in the air inlet cavity faster. At the same time, the ventilation pipe is connected to the combustion plate. Afterwards, the air flow in the air inlet chamber can only enter the combustion plate from other ventilation holes, which is beneficial to the more uniform oxygen supply in the combustion plate, thereby improving the combustion rate of the fuel.

Further, the furnace body is provided with a feeding cylinder with one end open, the open end of the feeding cylinder is connected to the feeding hopper, the closed end of the feeding cylinder is fixedly connected with a motor, and the output shaft of the motor is fixedly connected with a screw rod; the furnace body A feeding port is provided on the wall body of the utility model, and the feeding port is connected with the feeding cylinder. Through the setting of the feeding cylinder, motor, screw rod and feeding port, the fuel can be directly put in from the feeding port. After the fuel enters the feeding cylinder, the rotation of the motor drives the rotation of the screw rod, and then the fuel is fed into the furnace core, so that the Fuel injection is more convenient.

Further, the connection between the feeding barrel and the feeding hopper is at 90°. The connection between the feeding barrel and the feeding hopper is at 90°. Because the feeding barrel is filled with fuel, it is in an oxygen-deficient state; while there is no fuel in the feeding hopper, it can effectively prevent the high temperature gas in the core from igniting the fuel in the feeding barrel.
