Description

Technical Field

[0001] This application relates to the field of gasifiers, and more specifically, to a household integrated biomass gasifier. Background Technology

[0002] Traditional biomass gasifiers have been around since the 20th century. These devices consist of a fuel hopper and a gasification chamber, connected to a stove via pipes. They operate using forced ventilation to produce combustible gas in oxygen-deficient conditions, allowing for continuous combustion with a single fuel addition. However, the presence of tar and uncontrollable harmful components and odors from the combustion process necessitates refueling every 30 minutes to an hour. Frequent opening of the gasifier lid leads to significant odor dispersion in the room, and the easy scattering of fuel pollutes the surrounding environment and makes ignition difficult. These drawbacks have prevented their widespread adoption.

[0003] In order to improve the automation level of boilers, small and medium-sized bathing and heating hot water boilers in my country's cities all adopt mechanical feeding. However, mechanical feeding cannot move the burning raw materials in time. If the raw materials are piled up for a long time, it will lead to incomplete combustion, resulting in uneven combustion products, which will further affect the combustion effect.

[0004] Currently, there is no household integrated biomass gasification stove on the market that can automatically feed and dispense materials to ensure complete combustion of the raw materials. Summary of the Invention

[0005] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below.

[0007] A feeding device, located on the side wall of the shell, is used to convey biomass feedstock into the combustion chamber;

[0008] Household integrated biomass gasification stoves also include:

[0009] The ash chamber is located below the combustion chamber;

[0010] The bottom plate is located between the combustion chamber and the ash chamber, and its surface has several filter holes that penetrate the combustion chamber and the ash chamber.

[0011] The stirring component, located on the base plate, is used to stir the raw materials that are burning or have already finished burning.

[0012] The stirring assembly comprises several stirring rods disposed on the base plate and spaced at a certain distance from the base plate surface, and a driving component for driving the stirring rods to rotate and contacting the base plate surface during rotation; the distance between each stirring rod in the radial direction on the base plate is different.

[0013] During operation, biomass raw materials enter the combustion chamber through a feeding device, and then the stirring rod spreads the raw materials evenly on the floor for combustion. This allows the raw materials to fully contact the air and achieve complete combustion. The rotation of the stirring rod also forces the furnace ash into the ash chamber, thus enabling timely waste recycling and improving utilization.

[0014] Furthermore, the rotating tube connected to the drive component is rotatably positioned at the center of the base plate;

[0015] Several grooves corresponding to the stirring rod are formed on the side wall of the rotating tube along the axial direction;

[0018] Furthermore, a groove is formed by recessing the outer wall portion of the rotating tube to provide a sliding groove;

[0019] The inner top part of the chute is recessed inward along the axial direction of the rotating tube, away from the bottom plate, and the inner wall of the recessed part penetrates into the rotating tube to form a slot that connects the rotating chute and the interior of the rotating tube.

[0020] The slider part passes through the slot and connects to the drive component.

[0021] Furthermore, the driving component includes a rotating shaft rotatably disposed inside the rotating tube and a guide groove for guiding the slider to move axially along the rotating tube;

[0022] A portion of the bottom plate inside the rotating tube protrudes to form a cylindrical platform, and a guide groove is formed on the outer wall of the cylindrical platform.

[0023] The guide groove extends along the circumference of the cylindrical platform, and its extension trajectory is inclined to the central axis of the cylindrical platform; the slider is partially embedded in the guide groove.

[0024] Furthermore, a fixed toothed ring is fixed to the inner wall of the rotating tube;

[0025] A rotating gear on a cylindrical platform that meshes with a fixed gear ring;

[0026] Among them, a residual gear is provided on the rotating shaft to mesh with the rotating gear, and the number of teeth of the residual gear is 1 / 6 of the circumference of the rotating shaft.

[0027] Furthermore, a vaporization assembly is provided above the combustion chamber, which consists of a vaporization plate and a gas pipe disposed above the vaporization plate; the gas pipe connects the outside world with the space above the vaporization plate.

[0028] Several vaporization holes are formed on the surface of the vaporization plate.

[0029] Furthermore, a dispersion plate is rotatably installed at the bottom of the gasification plate, and there is a certain gap between the surface of the dispersion plate and the bottom of the gasification plate.

[0030] Dispersion grooves are formed through the surface of the dispersion plate;

[0031] The direction of the opening of the dispersion groove is inclined to the surface of the dispersion plate.

[0032] Furthermore, several dispersion grooves are distributed along the circumference of the dispersion plate;

[0033] The lengths of two adjacent dispersion grooves on the dispersion plate are different in the radial direction of the dispersion plate.

[0034] Furthermore, an air intake plate is formed on the outside of the casing above the combustion chamber;

[0035] The gas collecting plate extends around the circumference of the shell.

[0036] Among them, the gas collecting plate extends radially from the outer wall of the shell and then axially toward the combustion chamber.

[0037] Furthermore, a rotating groove corresponding to the dispersing plate is formed at the bottom of the gasification plate, and the rotating groove extends around the circumference of the gasification plate; and the side wall portion of the dispersing plate protrudes and inserts into the rotating groove, so that a cavity is formed between the dispersing plate and the gasification plate.

[0069] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0070] A household integrated biomass gasification stove includes: a shell 1, a feeding device 2, an ash chamber b1, a bottom plate 3, and a stirring assembly 4;

[0071] The shell 1 is constructed such that it has a combustion chamber a1 for burning raw materials inside the shell 1, and at least one feed inlet a11 is formed on the surface of the combustion chamber a1 to enter the interior of the combustion chamber a1; the feeding device 2 is a screw feeder, and the discharge port of the screw feeder is connected to the feed inlet a11; the feeding device 2 can automatically feed the biomass raw materials into the combustion chamber a1, thus improving convenience;

[0072] A bottom plate 3 for placing biomass raw materials is fixedly provided on the inner wall of the combustion chamber a1. The surface of the bottom plate 3 is flush with or lower than the side of the feed inlet a11. An ash chamber b1 for collecting ash after the biomass raw materials are formed below the bottom plate 3. Specifically, a number of filter holes a3 are formed on the surface of the bottom plate 3, penetrating the combustion chamber a1 and the ash chamber b1. The pore size of the filter holes a3 is smaller than that of the biomass raw materials.

[0073] More specifically, the surface of the base plate 3 is provided with an agitation component 4 for agitating the raw materials that are burning and have already been burned; the agitation component 4 can agitate the raw materials that are burning to make the combustion more complete, so that the smoke generated by the combustion of raw materials will not be unstable due to the combustion supplement; during the agitation process, the ash generated after combustion can also be agitated, so that it falls from the filter hole a3 into the ash chamber b1.

[0074] The stirring assembly 4 comprises several stirring rods 41 disposed on the base plate 3 and spaced at a certain distance from the surface of the base plate 3, and a driving component 42 for driving the stirring rods 41 to rotate and contacting the surface of the base plate 3 during rotation; more specifically, the radial distance between each stirring rod 41 on the base plate 3 is different; preferably, the stirring rods 41 are arc-shaped, and vent holes a41 are provided on the surface of the stirring rods 41; the arrangement of stirring rods 41 of different lengths can fully stir the raw materials on the base plate 3, so that the raw materials are evenly spread on the base plate 3; this can make the combustion more uniform and the raw materials more fully utilized; since the vent holes a41 are provided, air can be connected during stirring, thus preventing the flame from going out during stirring.

[0075] More specifically, the rotating tube 421 connected to the drive unit 42 is rotatably positioned at the center of the base plate 3; several grooves a421 corresponding to the stirring rod 41 are formed on the side wall of the rotating tube 421 along the axial direction, and the grooves a421 partially extend into the interior of the rotating tube 421; wherein, the grooves a421 are recessed in the outer wall portion of the rotating tube 421 to form a groove a421; the inner top portion of the groove a421 is recessed in the axial direction of the rotating tube 421 away from the base plate 3, and the inner wall of the recessed portion extends into the interior of the rotating tube 421 to form a slot b421 connecting the rotating groove b51 and the interior of the rotating tube 421, and the slider 422 partially passes through the slot b421 and is connected to the drive unit 42; in the initial state, the slider 422 is located at the upper end of the slot b421 so that the stirring rod 41 is higher than the surface of the base plate 3; since a gap is formed between the stirring rod 41 and the surface of the base plate 3, air circulation is ensured, making combustion more complete;

[0076] More specifically, the driving component 42 includes a rotating shaft 428 rotatably disposed inside the rotating tube 421 and a guide groove a423 for guiding the slider 422 to move axially along the rotating tube 421; a cylindrical platform 423 is formed by a protrusion on the surface of a portion of the bottom plate 3 inside the rotating tube 421, and the guide groove a423 is formed on the outer wall of the cylindrical platform 423; wherein, the guide groove a423 extends along the circumferential direction of the cylindrical platform 423, and the extension trajectory is inclined with the central axis of the cylindrical platform 423; the slider 422 is partially embedded in the guide groove a423;

[0077] More specifically, a fixed gear ring 424 is fixedly mounted on the inner wall of the rotating tube 421; a rotating gear 425 is rotatably mounted on the cylindrical platform 423 and meshes with the fixed gear ring 424; a residual gear 426 is mounted on the rotating shaft 428 and meshes with the rotating gear 425, the number of teeth of the residual gear 426 being 1 / 6 of the circumference of the rotating shaft 428; a driver 427, which is a motor, is provided in the ash chamber b1 to drive the rotating shaft 428 to rotate; when the rotating shaft 428 rotates, the residual gear 426 intermittently drives the rotating gear 425 to rotate. Then, the rotating tube 421 is driven to rotate at a certain angle; thus, the stirring rod 41 set on the rotating tube 421 can rotate intermittently to agitate the raw materials intermittently; through intermittent agitation, there is sufficient time for combustion, and the combustion process will not be interrupted or reduced due to the continuous rotation causing the raw materials to be agitated frequently; since the slider 422 can slide along the guide groove a423 when rotating, it can be driven to move downward, so that the stirring plate can be pressed against the surface of the bottom plate 3, thus squeezing into the ash chamber b1, improving the ash collection effect.

[0078] More specifically, a gasification assembly 5 is installed above the combustion chamber a1. The gasification assembly 5 consists of a gasification plate 51 and a gas pipe 52 installed above the gasification plate 51. The gas pipe 52 connects the outside world with the space above the gasification plate 51. Several gasification holes a51 are formed on the surface of the gasification plate 51. The products generated by the combustion of raw materials in the combustion chamber a1 enter the gasification holes a51 and mix with the outside air in the gas pipe 52 to form a mixture. This mixture can then be burned. A pot 53 can be installed above the gasification plate 51 for direct use, improving the convenience for civilian use.

[0079] More specifically, a dispersing plate 54 is rotatably mounted at the bottom of the gasification plate 51, with a certain distance between the surface of the dispersing plate 54 and the bottom of the gasification plate 51. A fixing rod 541 fixedly connected to the rotating shaft 428 is provided at the bottom of the dispersing plate 54. A rotating groove b51 corresponding to the dispersing plate 54 is formed at the bottom of the gasification plate 51, and the rotating groove b51 extends around the circumference of the gasification plate 51. The side wall portion of the dispersing plate 54 protrudes and inserts into the rotating groove b51, so that a cavity c51 is formed between the dispersing plate 54 and the gasification plate 51.

[0080] More specifically, a dispersion groove a54 is formed through the surface of the dispersion plate 54; wherein, the extension direction of the groove opening of the dispersion groove a54 is inclined to the surface of the dispersion plate 54; thus, when the dispersion plate 54 rotates, the smoke can enter the cavity c51 evenly through the dispersion groove a54, and then evenly contact each vaporization hole a51; thus making the combustion more uniform.

[0081] Preferably, several dispersion grooves a54 are distributed along the circumference of the dispersion plate 54; the lengths of two adjacent dispersion grooves a54 on the dispersion plate 54 in the radial direction of the dispersion plate 54 are different; this arrangement allows the smoke to pass through the dispersion grooves a54 more evenly into the cavity c51.

[0082] More specifically, an air collecting plate 6 is formed on the outside of the shell 1 above the combustion chamber a1; the air collecting plate 6 extends around the circumference of the shell 1; wherein, after the radial extension portion of the outer wall of the shell 1, the air collecting plate 6 extends axially towards the combustion chamber a1; because the heat at the combustion chamber a1 is high, the air at the outer shell located in the combustion chamber a1 is heated and rises, and then enters the air collecting plate 6, thus collecting more external air, allowing the external air to enter the cavity c51 more fully and combine with the flue gas.

[0083] In another preferred embodiment, the base plate 3 is annular and rotatably disposed on the inner wall of the combustion chamber a1; and part of the base plate 3 is connected to the side wall of the rotatable fixed rod so that the fixed rod can drive the base plate 3 to rotate synchronously when it rotates.

[0084] A cover 7 is fixedly installed at the bottom of the ash chamber b1, which forms an ash guiding surface a7; and a fixing plate 71 is fixedly installed at the upper end of the cover 7 and is rotatably connected to the side wall of the bottom plate 3; specifically, the cylindrical platform 423 is rotatably embedded in the fixing plate 71; furthermore, a portion of the surface of the fixing plate 71 is concave to form a rotating ring for the cylindrical platform 423 to rotate accordingly, and the cylindrical platform 423 is partially embedded in the rotating ring.

[0085] More specifically, a portion of the filter hole a3 at a certain radial distance from the wall of each filter hole a3 is recessed to form a sliding cavity 8. A clogging assembly for the filter hole a3 is provided within this sliding cavity 8. The clogging assembly includes a sliding plate 81 disposed within and corresponding to the sliding cavity 8. A clogging ring 82 corresponding to each filter hole a3 is disposed on the sliding plate 81, and the outer wall of the clogging ring 82 contacts the inner wall of the filter hole a3. A portion of the inner wall of the filter hole a3 extends into the sliding cavity 8 to form a moving groove 83. A portion of the sliding plate 81 protrudes and inserts into the moving groove 83, connecting with the outer wall of the clogging ring 82, so that the movement of the sliding plate 81 can drive the clogging ring 82 to slide along the extension direction of the moving groove 83. During use, ash may become stuck in the filter hole a3. The sliding plate drives the clogging ring 82 to slide intermittently along the axial direction within the filter hole a3, allowing the clogging ring 82 to scrape off the ash adhering to the inner wall of the filter hole a3.

[0086] More specifically, the outer wall of the fixed plate is concave in the circumferential direction to form a guide portion 84 for the guide slide plate 81 to move in the axial direction of the filter hole a3. The extension trajectory of the guide portion 84 is a wavy line. The inner wall portion of the base plate 3 extends into the sliding cavity 8 to form a notch 85. The side wall portion of the slide plate 81 protrudes towards the notch 85 to form a guide rod 86. The end of the guide rod 86 is rotatably provided with a roller 87 whose surface abuts against the surface of the guide portion 84. This is so that when the base plate 3 rotates, the roller 87 can be fixed along the surface of the guide portion 84 and drive the slide plate 81 to move up and down.

[0087] Preferably, the guide section 84 is composed of a concave arc surface a84 and a convex arc surface a85 arranged in a circular array along the circumference; and the curvature of two adjacent concave arc surfaces a84 and convex arc surfaces a85 is different; therefore, the movement range of the slide plate 81 will be different, and thus the distance that the unblocking ring 82 moves at the hole wall of the filter hole a3 will also be different. This makes it more effective to scrape off the furnace ash adhering to the inner wall of the filter hole a3, thus improving the cleaning effect.

[0088] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept.
