Description
Technical Field
[0001] This utility model relates to the field of earthen stove technology, specifically a novel earthen stove gasification furnace. Background Technology
[0002] In the process of boiling soy milk in soybean product processing, the traditional aroma of soy milk can be restored by using a traditional earthenware pot gasification furnace, satisfying consumers' pursuit of the taste of traditional soybean products and meeting national environmental protection requirements.
[0003] A Chinese patent discloses a combined soy milk maker (authorization announcement number CN211632754U). This patented technology uses biomass pellet fuel as the combustion energy source, avoiding wood consumption, and is clean, high in heat energy, producing soy milk with the same rich aroma as soy milk cooked in a wood-fired stove. The biomass pellet burner is combined with a cylindrical base, and the two can be detached and moved independently, making it very convenient to use. However, it cannot ensure complete combustion of the fuel, resulting in more smoke and a greater environmental impact, and it cannot effectively treat the smoke. Utility Model Content

[0023] Please see Figures 1-6 In this embodiment of the utility model, the novel earthen pot gasifier includes a gasifier 1 and an earthen pot 3 embedded and welded onto the gasifier 1. A fuel inlet 2 is provided on one side of the gasifier 1, and a feeding mechanism 4 is embedded and installed on the other side of the gasifier 1. A smoke exhaust mechanism 5 is embedded and installed on the upper end of one side of the gasifier 1 near the feeding mechanism 4, and an air supply combustion chamber 6 is installed at the lower end of the inner side of the gasifier 1. Pulleys 7 are installed at the four corners of the lower end of the gasifier 1, so that the entire earthen pot gasifier can be moved conveniently.
[0024] exist Figure 2 and Figure 3In the combustion chamber 6, the air-supply combustion chamber 6 includes a combustion chamber body 61. A feed port 68 is provided at one end of the combustion chamber body 61, and an air supply pipe 64 is fixedly connected to the other end of the combustion chamber body 61. A blower 63 is installed at one end of the air supply pipe 64. A combustion groove 67 is provided at the upper end of the combustion chamber body 61, and several support blocks 65 are installed on the front and rear sides of the upper end of the combustion chamber body 61 near the combustion groove 67. Several air outlets 66 are provided on the inner and upper side walls of the combustion groove 67. A ventilation duct 62, connected to the air supply pipe 64, is provided inside the combustion chamber body 61 outside the combustion groove 67. Strip-shaped or block-shaped fuels are fed from the feed port 68. Fuel is added to the combustion chamber 67 and ignited. The fuel can be firewood or coal. The fuel burns in the combustion chamber 67. External air is sent into the ventilation duct 62 by the blower 63 and the air supply pipe 64. The air then escapes from the air outlet 66, which makes the fuel in the combustion chamber 67 burn completely, thereby greatly reducing the generation of flue gas and improving the working environment. The air supply pipe 64 runs through one side of the gasifier 1, and the blower 63 is installed on the outside of the gasifier 1, so that external air can be sent into the ventilation duct 62. The feeding port 68 is embedded inside the fuel inlet 2, so that fuel can be added into the combustion chamber 67 from the fuel inlet 2.
[0025] exist Figure 2 and Figure 4 In the process, the feeding mechanism 4 includes a hopper 43, the lower end of which is connected to a first cylindrical shell 41. A second cylindrical shell 45 is installed at one end of the first cylindrical shell 41, and a motor 42 is installed at the other end of the first cylindrical shell 41. The output end of the motor 42 is fixedly connected to an auger shaft 44. A discharge port 46 is opened at one end of the second cylindrical shell 45. The first cylindrical shell 41 is installed on the outside of the gasifier 1, and the second cylindrical shell 45 is installed on the inside of the gasifier 1. The auger shaft 44 passes through the first cylindrical shell 41 in sequence. Inside the cylindrical shell 41, gasifier 1, and second cylindrical shell 45, the discharge port 46 is located above the combustion chamber 67. Therefore, when pellet fuel, such as pelleted carbon, is added into the hopper 43, the auger shaft 44 is rotated by the motor 42. The pellet fuel in the hopper 43 enters the first cylindrical shell 41 and is then fed into the second cylindrical shell 45 by the auger shaft 44. It then falls from the discharge port 46 into the combustion chamber 67 for combustion. Thus, pellet fuel can be burned when firewood or coal is not burned.
[0026] exist Figure 2 and Figure 5In the process, the smoke exhaust mechanism 5 includes an ash collection cylinder 51 and an ash cylinder cover 53 installed on the upper end of the ash collection cylinder 51. A movable ash collection box 52 is provided at the lower end of the ash collection cylinder 51, and an inlet pipe 58 is connected to the outside of the ash collection cylinder 51. A filter cartridge 57 is installed inside both the ash collection cylinder 51 and the ash cylinder cover 53. An induced draft fan 55 is connected to the upper end of the ash cylinder cover 53 through an exhaust pipe 54. An air outlet 56 is provided at the output end of the induced draft fan 55. The ash collection cylinder 51 and the movable ash collection box 52 are connected to the lower end of the ash collection cylinder 51. A valve 59 is installed between the ash boxes 52. The flue gas generated by fuel combustion enters the ash collection cylinder 51 through the flue gas inlet pipe 58. The soot in the flue gas is intercepted by the outside of the filter cartridge 57. The purified flue gas enters the exhaust pipe 54 through the ash cylinder cover 53, and is then drawn into the air outlet 56 by the induced draft fan 55 and discharged, thereby effectively protecting the environment. After the induced draft fan 55 is turned off and the valve 59 is opened, the soot in the ash collection cylinder 51 can be discharged into the mobile ash collection box 52.
[0027] exist Figure 2 and Figure 6 In the process, the earthen pot 3 includes an earthen pot body 31. The outer side of the upper end of the earthen pot body 31 is provided with a rolled edge 32, and a drain outlet 33 is provided at the bottom of the inner side of the earthen pot body 31. The cross-section of the earthen pot body 31 is a U-shaped structure, which makes its heating area large, the pot boiling fast, and saves fuel. The earthen pot body 31 is welded together with the gasifier 1, which makes its integrity better. Water in the earthen pot body 31 can be discharged through the drain outlet 33.
[0028] The working principle of this utility model is as follows: When using strip-shaped or block-shaped fuels such as firewood or coal, firewood or coal is placed into the combustion chamber 67 through the fuel inlet 2 and ignited; then, the blower 63 is turned on, and external air is sent into the ventilation duct 62 through the air supply pipe 64, and the air then escapes from the air outlet 66, so that the fuel in the combustion chamber 67 is fully burned, heating the food in the pot body 31; at the same time, the induced draft fan 55 is turned on, so that the flue gas generated by the fuel combustion enters the ash collection cylinder 51 through the smoke inlet pipe 58. After the soot in the flue gas is intercepted by the outside of the filter cylinder 57, the purified flue gas enters the exhaust pipe 54 through the ash cylinder cover 53, and is then drawn into the air outlet 56 by the induced draft fan 55 and discharged.
[0029] When solid pellet fuel is used for combustion, the motor 42 is started, and the motor 42 drives the auger shaft 44 to rotate. The pellet fuel in the hopper 43 enters the first cylindrical shell 41 and is then fed into the second cylindrical shell 45 by the auger shaft 44. It then falls from the discharge port 46 into the combustion chamber 67 for combustion.
[0030] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
