[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0025] Specific implementation examples are given below.
[0026] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5 This utility model provides an energy-saving and environmentally friendly coal-fired hot air stove, including a furnace shell 1; characterized in that: a feed inlet 11 is fixedly connected to the side wall of the furnace shell 1; an exhaust port 12 is opened at the end of the furnace shell 1; a coal burning plate 13 is fixedly connected to the inner side wall of the furnace shell 1; an oxygen generator 14 is fixedly connected to the side wall of the furnace shell 1; multiple sets of air guide pipes 15 are provided at the output end of the oxygen generator 14; the air guide pipes 15 penetrate the side wall of the furnace shell 1 and are located inside the furnace shell 1; a fixing plate 16 is symmetrically fixedly connected to the bottom end of the coal burning plate 13; a first electric push rod 17 is symmetrically fixedly connected to the side wall of the fixing plate 16; an assembly plate 18 is provided at the output end of the first electric push rod 17; multiple sets of spring assemblies 19 are provided on the inner side wall of the assembly plate 18; a collision plate 101 is fixedly connected to the end of the spring assembly 19; the collision plate 101... 01 is set at the bottom of the coal burning plate 13; during the coal combustion process, the oxygen generator 14 is started to generate oxygen, which is blown axially to the coal burning plate 13 through the air guide pipe 15, acting on the coal to improve the coal combustion effect. At the same time, the first electric push rod 17 on one side is started to move up and down in a regular manner, so that the collision plate 101 impacts the coal burning plate 13 in a regular manner, causing the coal burning plate 13 to vibrate. At the same time, the vibration frequency of the collision plate 101 is increased by the spring assembly 19, which improves the vibration effect on the coal burning plate 13. By making the coal burning plate 13 vibrate, the ash shell on the outside of the coal falls off at a faster speed, exposing the coal core that is burning inside, and accelerating the contact area and rate between oxygen and the coal core. Through the set oxygen supply and vibration mechanism, the combustion speed of the coal is accelerated, thereby improving the coal combustion effect and saving coal energy.
[0027] Furthermore, such as Figure 2 , Figure 4 As shown, a connecting pipe 2 is provided at one end of the furnace shell 1; connecting blocks 21 are symmetrically arranged on the inner side wall of the connecting pipe 2; a motor 22 is fixedly connected to the end of the connecting block 21; a fan rod 23 is provided at the output end of the motor 22; a guide pipe 24 is fixedly connected to the end of the connecting pipe 2; when gas is discharged upward through the exhaust port 12, the motor 22 is started to drive the fan rod 23 to rotate, accelerating the gas flow, and reducing the gas discharge area through the guide pipe 24. By accelerating the gas flow, the gas discharge speed is increased, reducing the situation of poor internal gas flow caused by coal combustion gas accumulation, increasing the oxygen flow space, and thus improving the coal combustion effect.
[0028] Furthermore, such as Figure 4 As shown, a fixed sliding groove 3 is provided on the inner side wall of the guide tube 24; multiple sets of filter plates 31 are slidably connected to the side wall of the fixed sliding groove 3; through the multiple sets of filter plates 31, the gas generated by coal combustion is filtered in multiple layers, reducing the amount of harmful gas discharged and improving the cleanliness of the surrounding air.
[0029] Furthermore, such as Figure 2 As shown, a positioning sleeve 4 is symmetrically fixed to the side wall of the furnace shell 1; a second electric push rod 41 is fixed to the inner side wall of the positioning sleeve 4; the second electric push rod 41 is slidably connected to the inner side wall of the furnace shell 1; a push plate 42 is fixed to the output end of the second electric push rod 41; by activating the second electric push rod 41, the push plate 42 is pushed to slide towards the center, pushing the coal, which facilitates pushing the burned coal into the slot of the coal burning plate 13 for cleaning, thus improving the convenience of cleaning.
[0030] Furthermore, such as Figure 2 As shown, the pusher plate 42 is provided with pusher bars 5 on its side wall; when the pusher plate 42 moves, the inclined arrangement of the pusher bars 5 facilitates the accumulation of coal that has been burned, thereby increasing the amount of coal pushed.
[0031] Furthermore, such as Figure 4 As shown, the filter plates 31 are arranged at different rotation angles. By making the rotation angle of each set of filter plates 31 different, when the gas is discharged upward, the gas needs to be deflected in the interlayer of the filter plates 31, thereby increasing the interaction area between the gas and the filter plates 31 and improving the filtration effect.
[0032] Working principle: During coal combustion, the oxygen generator 14 is activated to produce oxygen, which is then blown axially onto the coal combustion plate 13 through the gas pipe 15, acting on the coal to improve combustion efficiency. Simultaneously, the first electric push rod 17 on one side is activated to perform a regular up-and-down movement, causing the collision plate 101 to regularly impact the coal combustion plate 13, resulting in vibration. The spring assembly 19 further increases the vibration frequency of the collision plate 101, enhancing the vibration effect on the coal combustion plate 13. This vibration accelerates the shedding of the ash shell from the coal, exposing the burning coal core and increasing the contact area and rate between oxygen and the coal core. When the gas is discharged upwards through the exhaust port 12, the electric push rod 17 is activated. The machine 22 drives the fan rod 23 to rotate, accelerating the gas flow and reducing the gas emission area through the guide tube 24. Through the multiple sets of filter plates 31, the gas produced by coal combustion is filtered in multiple layers, reducing the amount of harmful gases emitted. By activating the second electric push rod 41, the push plate 42 is pushed to slide towards the center, pushing the coal material, which facilitates pushing the burned coal material into the slot of the coal burning plate 13. When the push plate 42 moves, the inclined setting of the push bar 5 facilitates the accumulation of the burned coal material. By making the rotation angle of each set of filter plates 31 different, when the gas is discharged upward, the gas needs to be deflected in the interlayer of the filter plates 31, thereby increasing the interaction area between the gas and the filter plates 31.
[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
