Description

Technical Field

[0001] The invention belongs to the field of heating equipment, and in particular relates to a heating stove. Background Art

[0002] Heating stoves are common heating equipment, mainly including return air stoves, biomass pellet heating stoves, electric heaters, 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 characteristics of large firepower and wide heat coverage. This type of heating stove includes a stove surface, a stove body, a stove core, a base, an ash removal device and an ash box, etc.; the stove core is the core component of the heating stove; the current stove core is mainly a core body that penetrates the axial direction. When in use, place the stove core in the stove body until its bottom contacts the ash removal device on the base; then put the fuel into the core and ignite it, and the fuel provides oxygen for the combustion of the fuel through the air inlet set on the stove body. This method realizes the continuous combustion of the fuel, but because the wind flow transmitted by the air inlet accumulates at the bottom of the core, the wind flow is almost consumed at the bottom of the core, and the fuel has not yet been completely burned, so a large amount of smoke will be generated, and the fuel will not be burned fully, 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, which makes the temperature of the stove surface rise slowly, and is not conducive to daily operations such as steaming and cooking food.

[0003] To address this problem, the applicant further improved the furnace core, thereby increasing the intensity of the flame at the top of the core and reducing the amount of fuel used, thereby further reducing fuel waste. Summary of the invention

[0004] The present invention is intended to provide a heating stove to solve the problem that the heating stove in the prior art needs to burn a large amount of fuel to quickly heat up the stove surface.

[0005] A heating stove in the present 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, the furnace body is fixedly connected to the base, and 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; the base is provided with air supply holes, and the air supply holes are located between the furnace body and the furnace core; the furnace core includes a core body passing through the axial direction, and a plurality of ventilation holes communicating with the interior of the core body are arranged on the wall of the core body, and the ventilation holes are located in the upper half of the core body.

[0006] The working principle and beneficial effects of this scheme are as follows: when in use, the fuel is placed in the furnace core and ignited; the fuel burns at the bottom of the furnace core, and the degree of fuel combustion can be controlled by controlling the opening size of the air inlet. The incompletely burned fuel forms a mixed combustible gas that quickly rises to the upper half of the furnace core; since the base is provided with an air supply hole, the air supply hole is located between the furnace body and the furnace core; the outside air will enter the furnace body from the air supply hole on the base, and due to the combustion of the fuel inside the furnace core, the temperature of the air inside the furnace body is relatively high, thereby allowing a large amount of outside air to enter the furnace body; the air entering the furnace body enters the core from the ventilation hole and quickly replenishes oxygen to the combustible gas, prompting the incompletely burned mixed combustible gas to undergo secondary combustion. Since the fuel in the upper half of the core is close to the furnace surface when burning, the flame it produces can directly act on the furnace surface, prompting the rapid increase in the furnace surface temperature. Therefore, the heating stove in this scheme can also achieve a rapid increase in the furnace surface temperature while using less fuel, greatly reducing fuel waste.

[0007] Furthermore, the ash removal device includes a pull rod and an ash removal plate, one end of the pull rod is fixedly connected to the ash removal plate; the ash removal plate is provided with an ash leakage hole, and the bottom of the ash removal plate is slidably connected with an ash baffle plate for sealing the ash leakage hole; the end of the pull rod away from the ash removal plate passes through the base and extends outside the base; the ash removal plate is located directly above the ash box; and a support plate for supporting the ash baffle plate is provided on the base. The ash removal device in the prior art generally uses a furnace bridge. When the furnace bridge removes ash, the fuel is easy to fall into the ash box from the gap of the furnace bridge; and when the furnace bridge is pulled, it is also easy to cause the fuel to be broken, thereby further aggravating the loss of fuel. By providing an ash removal plate, an ash baffle plate and an ash leakage hole; when the ash generated after the fuel is burned fills the ash leakage hole on the ash removal plate, the pull rod pulls the ash removal plate, at this time, the ash in the ash leakage hole 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 plate, and the upper surface of the filling part of the ash removal plate supports the fuel to continue to burn. When the ash hole is pulled away from the ash baffle, the ash material without the support of the ash baffle falls into the ash box below. After the ash falls into the ash box, the ash removal plate is pushed by the pull rod until the ash hole is directly below the furnace core; during this process, the ash baffle can support the ash material again, so that it can be used continuously.

[0008] Furthermore, a feed hopper is detachably connected to the outer wall of the core body, and the feed hopper is connected to the core body. The provision of the feed hopper makes the feeding process into the core body more convenient.

[0009] Furthermore, two connecting holes are provided on the wall of the core body, and the two connecting holes are respectively connected to an air supply device and an igniter, and the connecting holes are located in the lower half of the core body. The arrangement of the air supply device and the igniter facilitates the ignition of the fuel in the core body and the delivery of air.

[0010] Furthermore, the bottom of the core body is detachably connected to a combustion disk that passes through the axial direction, and the connection hole is set on the wall of the combustion disk. During the combustion process of the furnace core, the bottom of the core body is connected to the air supply device and the igniter, and it is heated more, which causes the lower half of the core body to be easily worn out, thereby reducing the overall service life of the core body. The core body and the combustion disk are used to form the furnace core, so that the combustion disk is heated more, and when it is damaged, it can be replaced in time, thereby increasing the service life of the core body and reducing the overall consumption of the furnace core.

[0011] Furthermore, the combustion disk is sleeved with a ventilation cavity, and the wall of the ventilation cavity is provided with mounting holes for the air supply device and the igniter to pass through, and the combustion disk is also provided with a plurality of air adjustment holes. Through the arrangement of the ventilation cavity and the air adjustment holes, when in use, the air outlet of the air supply device is located in the ventilation cavity, so that the air flow generated by the air supply device is divided into the plurality of air adjustment holes, and then enters the combustion disk from the air adjustment holes, so that multiple positions of the combustion disk are supplemented with oxygen, which is conducive to the balanced combustion of the fuel in the combustion disk.

[0012] Furthermore, the air supply device is a fan, and 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 the ventilation pipe is connected to an air guide pipe; the fan is connected to one end of the air inlet cavity, and the end of the air guide pipe away from the ventilation pipe is located in the air inlet cavity. When 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 stove. The fuel is put into the core, the fan and the heating device are started, and the wind flow generated by the fan is divided into two parts and enters the air inlet cavity and the air guide pipe. When the wind flow in the air guide pipe passes through the ventilation pipe, it is heated by the heating device to become hot air with high temperature. The hot air enters the core from the ventilation pipe to ignite the fuel. After the fuel is ignited, the heating device is turned off, and then the cold air generated by the fan continuously passes through the air inlet cavity and the ventilation pipe to provide oxygen for the fuel. During the fuel combustion process, since the cold air continuously passes through the ventilation pipe, the influence of the heat generated by the fuel combustion on the ventilation pipe is greatly reduced, thereby increasing the service life of the ventilation pipe and the heating device.

[0013] Furthermore, the air guide duct and the ventilation duct are both located in the air inlet cavity. Arranging the air guide duct and the ventilation duct in the air inlet cavity helps to reduce the overall structure of the igniter. More importantly, after the air guide duct and the ventilation duct are arranged in the air inlet cavity, the two occupy a large amount of space in the air inlet cavity, so that the air flow velocity in the air inlet cavity is accelerated. At the same time, after the ventilation duct is connected to the combustion disk, the air flow in the air inlet cavity can only enter the combustion disk from other ventilation holes, which is conducive to a more uniform oxygen supply in the combustion disk, thereby improving the combustion rate of the fuel.

[0014] Furthermore, a feeding tube with an open end is provided in the furnace body, the open end of the feeding tube is connected to the feeding hopper, a motor is fixedly connected to the closed end of the feeding tube, and a spiral rod is fixedly connected to the output shaft of the motor; a feeding port is provided on the wall of the furnace body, and the feeding port is connected to the feeding tube. Through the arrangement of the feeding tube, the motor, the spiral rod and the feeding port, the fuel can be directly put in from the feeding port. After the fuel enters the feeding tube, the rotation of the motor drives the spiral rod to rotate, and then the fuel is fed into the furnace core, making the feeding of the fuel more convenient.

[0015] Furthermore, the connection between the feed tube and the feed hopper is 90 degrees. Since the feed tube is filled with fuel and is in an oxygen-deficient state, and there is no fuel in the feed hopper, it is effectively prevented that the high-temperature gas in the core body ignites the fuel in the feed tube.

A plurality of air regulating holes 37 are also arranged around the combustion disk 35, and the plurality of air regulating holes 37 are evenly distributed on the wall of the combustion disk 35, and the air regulating holes 37 and the connecting holes 33 are located in the same horizontal plane; the air regulating holes 37 are truncated cone-shaped, and the aperture of the air regulating holes 37 on one side of the ventilation cavity 36 is smaller than that on the other side.

[0029] Ignition device 10 is as attached Figure 7 As shown, it includes a ventilation pipe 106, a heating pipe 104, a blower 101 and an air inlet chamber 102, one end of the ventilation pipe 106 is connected to the heating pipe 104, the ventilation pipe 106 is connected to the air guide pipe 103, the ventilation pipe 106 passes through the wall of the air guide pipe 103, and the wall of the ventilation pipe 106 is surrounded by an air inlet hole 105, the air inlet hole 105 is located in the air guide pipe 103 and connected to the air guide pipe 103, and the air outlet of the ventilation pipe 106 is conical; the blower 101 is connected to one end of the air inlet chamber 102, the air guide pipe 103 and the ventilation pipe 106 are both located in the air inlet chamber 102, and the air inlet of the air guide pipe 103 is located directly above the air outlet of the air supply device; the ventilation pipe 106 is connected to the connecting hole 33, and the air inlet chamber 102 is connected to the chamber.

[0030] The heating stove in embodiment 4 is basically as shown in the attached Figure 8 As shown, the difference between Example 4 and Example 3 is that: a feeding cylinder 11 with an open end is provided in the furnace body 5, the open end of the feeding cylinder 11 is connected to the feed hopper 34, the connection between the feeding cylinder 11 and the feed hopper 34 is 90°, the closed end of the feeding cylinder 11 is fixedly connected to the motor 12, and the output shaft of the motor 12 is fixedly connected to the screw rod 13; a feeding cavity is provided on the wall of the furnace body 5, the feeding cavity includes a feeding port 14, and the feeding port 14 is connected to the feeding cylinder 11.

[0031] Taking Example 4 as an example, when in use, the biomass particles are fed into the feeding tube 11 through the feeding port 14, the motor 12 is started, and the motor 12 drives the screw rod 13 to rotate, thereby transporting the biomass particles to the combustion disk 35; the blower 101 and the heating tube 104 are started, and part of the wind flow generated by the blower 101 enters the ventilation tube 106 through the air guide tube 103, and the wind flow in the ventilation tube 106 is heated by the heating tube 104, and then enters the combustion disk 35 to ignite the biomass particles, and the heating tube 104 is closed.
