technical field

The utility model relates to the technical field of heating equipment, in particular to an environment-friendly heating furnace.

Background technique

Heating furnace, also known as heating furnace, belongs to a kind of civil domestic boiler, mainly refers to a normal pressure boiler that can meet people's heating needs, and belongs to the category of civil hot water boiler.

Facing the current increasingly severe environmental problems, the traditional coal-fueled heating stoves have received more and more attention due to serious pollution. Heating furnaces as fuels have received extensive attention, but electricity and gas can only be popularized and applied in areas with better economic conditions and relatively well-established power supply and gas supply systems, while the promotion in remote areas and rural areas is still limited by conditions and has great constraints . In remote areas and rural areas, biomass pellets and charcoal as clean energy are good environmentally friendly alternative fuels.

However, due to the limitation of the structure of the existing heating furnace, generally only one kind of fuel can be used, and only one of the biomass pellets and blue carbon can be used, which greatly restricts the channels for users to obtain fuel;

For example, the Chinese utility model patent with the patent number of 201720227540.2 discloses a biological particle heating furnace. The biological particle heating furnace mainly includes a base, and a combustion chamber and an ash box are arranged on the pedestal. The ash box is located below the combustion chamber. The combustion chamber at least includes a flue gas outlet, a cavity for accommodating the combustion plate, and a heat exchange tube. The combustion plate is provided with an ignition device and a combustion air inlet in the lower space, and an adjustable feed inlet is arranged above the combustion plate, which can be The adjustable feeding port is connected with the material box; the heat exchange pipes are respectively connected with the air inlet and the air outlet. Although the biomass pellet heating furnace fuel based on the above structure uses clean energy biomass pellets and uses hot air heat exchange for heating, the biomass pellets are fully burned, and the combustion heat can be fully utilized. However, there are still the following technical defects: (1) The heating furnace of this structure can only use biomass particles as fuel. If blue charcoal is used as fuel, the char formed after the blue charcoal burns out will easily displace the combustion air inlet on the combustion plate. Blockage leads to insufficient fuel combustion, so the application of fuel for the heating stove of this structure is greatly restricted; (2) the heating stove of this structure can only be used for heating, not for cooking, and has a single structure.

Another example is the Chinese utility model patent with the patent number of 201821341234.2, which discloses a multifunctional heating furnace with blue charcoal as fuel, which includes a furnace body and a hearth. The water layer is communicated with the stovetop, and a black crystal plate is arranged on the stovetop, and the black crystal plate and the stovetop are sealed with high temperature resistant black glue. A feeding system is installed on the middle and upper part of the rear wall of the furnace body, and a secondary air supply pipe is arranged in the furnace chamber. The feeding system includes a hopper, a feeding device, a feeding box, a grate, and a blower. The secondary air supply pipe is connected to the blower, and the combustion area of the grate is provided with matrix air inlet holes. The feeding device is connected with a driving mechanism, which can move forward and backward to realize feeding. The inclination of the furnace grate is less than or equal to 17 degrees, and the hopper is equipped with a gas collecting device. Although the heating stove based on the above structure has a simple structure, integrates heating and cooking functions, and is convenient to use, it still has the following defects: (1) The heating stove of this structure cannot use biomass particles as fuel, because its furnace grates The placement inclination is less than or equal to 17 degrees, and the biomass particles are in the shape of short cylinders, which are easy to roll out of the combustion zone along the grate, resulting in waste of fuel, and a sufficient number of biomass particles cannot be accumulated on the grate, which cannot meet the (2) There is a problem that coke lumps cannot be automatically removed in the combustion zone on the grate of the heating furnace with this structure, resulting in insufficient fuel combustion and low heat conversion rate.

Therefore, in view of the above problems, an environment-friendly heating stove is developed, and its fuel can be one of biomass particles and blue carbon, or both can be used simultaneously, and the heating function and cooking function are integrated into one, which not only has urgent needs It also has good economic benefits and industrial application potential, which is the driving force and basis for the completion of the utility model.

As shown in Figure 3, the working principle of an environment-friendly heating stove of the present utility model is as follows:

When in use, open the bin cover 312, add one or both of the biomass pellets and charcoal to the storage hopper 32 from the feeding port 311, and the fuel enters the blanking structure 22 from the lower discharge port of the storage hopper 32. In the process, the controller is powered on, the controller controls the drive motor 232 to work, the drive motor 232 drives the feeding structure 231 to advance toward the combustion part 2111 via the drive link 233, and at the same time, the guide ejector plate 2312 pushes the discharge baffle 225 Open and the plough plate 23123 on it pushes the fuel forward, the fuel falls from the fuel outlet 222 to the upper support plate 211, and the pushing block 2311 pushes the fuel on the upper support plate 211 to the combustion part 2111, and at the same time pushes the combustion part 2111 The residual coke lumps and ashes on the ash are pushed down into the ash receiving hopper 17 by the ash falling gap 142;

After the feeding structure 231 completes the pushing of the fuel, it returns under the drive of the driving motor 232. During the return process, the discharge baffle 225 is slowly lowered to block the unloading of the fuel, prevent the fuel from spilling, and avoid waste;

During the above-mentioned whole process, the blower 2172 and the high-temperature-resistant blower are always on; the blower 2172 can not only support the combustion of fuel, but also cool down the drive motor 232, which greatly improves the service life of the drive motor 232, and also improves the The feeding part 2112 on the plate 211 is cooled, and the combustion part 2111 and the blanking structure 22 are cut off, thereby eliminating the potential safety hazard of backfire in the silo; the high temperature resistant fan can discharge the flue gas in the furnace 11 in time;

After the heating furnace provided by the utility model is used for a period of time, the smoke exhaust pipe 152 needs to be cleaned. During cleaning, the ash cleaning spring 155 in the smoke exhaust pipe 152 is pulled to remove the soot adhering to the inner wall of the smoke exhaust pipe 152. , the removed soot falls into the smoke exhaust cavity 151 along the exhaust pipe 152, and the ash cleaning blocking plate 1512 is opened irregularly to remove the soot in the exhaust cavity 151; in addition, the maintenance door 141 is opened irregularly to remove the ash receiving hopper Ashes in 17.
