Abstract
Description
Technical Field
[0001] This utility model relates to the field of biomass combustion furnace technology, and in particular to a household biomass combustion furnace. Background Technology
[0002] In recent years, the development and utilization of biomass energy has received increasing attention and is being gradually promoted and applied. Biomass fuel can be corn stalks, rice husks, peanut shells, corn cobs, etc. Biomass combustion furnaces can burn biomass fuel. Especially in rural areas, biomass fuel is inexpensive and readily available, and is safer than liquefied petroleum gas. Using biomass fuel for cooking is the preferred choice for cooking in rural areas today.
[0003] To reduce the number of times biomass fuel is added and extend its burning time, household biomass burners typically process corn stalks, rice husks, peanut shells, and corn cobs into blocks before burning them. However, after the biomass fuel is burned, it still retains its blocky structure, which can easily clog the ash discharge port when discharging combustion waste, causing inconvenience in ash discharge. Utility Model Content
[0004] The main objective of this invention is to provide a household biomass combustion stove that can effectively solve the problems in the background technology.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A household biomass combustion furnace includes a furnace body mechanism. A partition mechanism is fixedly connected to the inner center of the furnace body mechanism. A crushing mechanism is provided in the lower inner part of the furnace body mechanism. The crushing mechanism includes a drive chamber. Connecting plates are fixedly connected to the upper front and rear sides of the drive chamber. A rotating shaft is rotatably connected to the middle front side of the drive chamber. A handle is fixedly connected to the front end of the rotating shaft. A bevel gear one is fixedly connected to the rear end of the rotating shaft. A bevel gear two is meshed at the lower end of the bevel gear one. A drive rod is fixedly connected to the middle of the bevel gear two. A cutter is fixedly connected to the outer periphery of the lower middle part of the drive rod. A feeding auger is fixedly connected to the outer periphery of the lower end of the drive rod. The outer periphery of the upper middle part of the drive rod is rotatably connected to the middle opening of a limiting frame.
[0007] Preferably, the upper end of the furnace body structure is evenly distributed with pot support legs, and the lower outer periphery of the furnace body structure is evenly distributed with support legs.
[0008] Preferably, the furnace body structure includes an outer furnace body, an air inlet groove is fixedly connected to the lower front circumference of the outer furnace body, an air inlet cover is slidably connected inside the air inlet groove, a slag discharge cover is provided on the lower outer circumference of the outer furnace body, a heat insulation layer is fixedly connected inside the outer furnace body, and an inner furnace body is fixedly connected inside the heat insulation layer.
[0009] Preferably, the partition mechanism includes a partition ring, the outer periphery of which is fixedly connected to the inner center of the inner furnace body. Both sides of the inner center of the partition ring are rotatably connected to a mesh plate via a torsion spring hinge. The lower ends of the mesh plates are attached to limit rods, and the outer periphery of the limit rods are slidably connected to the inside of the limit cylinder.
[0010] Preferably, the outer periphery of the limiting rod is slidably connected to the middle of both sides of the outer furnace body, and the opposite ends of the limiting cylinders are fixedly connected to the middle of both inner sides of the inner furnace body.
[0011] Preferably, the ends of the connecting plates that are far apart are fixedly connected to the lower middle part of the inner front and rear sides of the inner furnace body, the front and rear ends of the limiting frame are fixedly connected to the lower end of the inner front and rear sides of the inner furnace body, and the outer periphery of the front end of the rotating shaft is rotatably connected to the lower middle part of the front end of the outer furnace body.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] After cooking, remove the limiting rods on both sides. Due to gravity, the mesh plates on both sides rotate, discharging the burnt residue into the bottom of the inner furnace body. Place the collection box under the slag discharge cover and open the slag discharge cover. Turn the handle to drive the shaft to rotate, which in turn drives bevel gear one to rotate bevel gear two, ultimately driving the cutter and the feeding auger to rotate. The cutter first chops the larger waste residue, and the chopped residue is evenly fed out of the inner furnace body and falls into the collection box. By first chopping the larger waste residue through the chopping mechanism and then evenly feeding it out of the inner furnace body, the larger waste residue is prevented from getting stuck at the discharge port at the bottom of the inner furnace body. Furthermore, dust is not scattered during the slag discharge process, making it easy to collect the residue. Attached Figure Description

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0020] like Figures 1-4 As shown, a household biomass combustion stove includes a furnace body mechanism 1. A partition mechanism 3 is fixedly connected to the inner middle of the furnace body mechanism 1. A crushing mechanism 2 is provided in the lower inner part of the furnace body mechanism 1. The crushing mechanism 2 includes a drive chamber 21. A connecting plate 22 is fixedly connected to the upper front and rear sides of the drive chamber 21. A rotating shaft 23 is rotatably connected to the middle of the front side of the drive chamber 21. A handle 24 is fixedly connected to the front end of the rotating shaft 23. A bevel gear 25 is fixedly connected to the rear end of the rotating shaft 23. A bevel gear 26 is meshed with the lower end of the bevel gear 25. A drive rod 27 is fixedly connected to the middle of the bevel gear 26. A cutter 28 is fixedly connected to the lower outer periphery of the drive rod 27. A feeding auger 29 is fixedly connected to the lower outer periphery of the drive rod 27. The upper outer periphery of the drive rod 27 is rotatably connected to the middle opening of the limiting frame 210.
[0021] In this embodiment, the partition mechanism 3 includes a partition ring 31. The outer periphery of the partition ring 31 is fixedly connected to the inner middle part of the inner furnace body 16. Both sides of the inner middle part of the partition ring 31 are rotatably connected to a mesh plate 32 by a torsion spring hinge. The lower end of the mesh plate 32 is attached to a limiting rod 33. The outer periphery of the limiting rod 33 is slidably connected to the inside of the limiting cylinder 34. The outer periphery of the limiting rod 33 is slidably connected to the middle of both sides of the outer furnace body 11. The opposite ends of the limiting cylinder 34 are fixedly connected to the middle of both sides of the inner furnace body 16. The opposite ends of the connecting plate 22 are fixedly connected to the lower middle part of the inner front and rear sides of the inner furnace body 16. The front and rear ends of the limiting frame 210 are fixedly connected to the lower end of the inner front and rear sides of the inner furnace body 16. The outer periphery of the front end of the rotating shaft 23 is rotatably connected to the lower middle part of the front end of the outer furnace body 11.
[0022] Specifically, after cooking is completed, the limiting rods 33 on both sides are removed. Due to gravity, the mesh plates 32 on both sides are forced to rotate, discharging the burnt residue into the bottom of the inner furnace body 16. The collection box is placed at the lower end of the slag discharge cover 14, and the slag discharge cover 14 is opened. The handle 24 is turned, which drives the rotating shaft 23 to rotate. Then, the first bevel gear 25 drives the second bevel gear 26 to rotate, which in turn drives the cutter 28 and the feeding auger 29 to rotate. The cutter 28 first cuts the larger waste residue. The cut residue is then evenly fed out of the inner furnace body 16 through the cutter 28 and falls into the collection box. The larger waste residue is first cut by the crushing mechanism 2 and then evenly fed out of the inner furnace body 16. This ensures that the larger waste residue will not get stuck at the discharge port at the lower end of the inner furnace body 16, and that dust will not be scattered during the slag discharge process, making it easy to collect the waste residue.
[0023] In this embodiment, the upper end of the furnace body mechanism 1 is evenly distributed with pot support legs 5, and the lower end of the furnace body mechanism 1 is evenly distributed with support legs 4. The furnace body mechanism 1 includes an outer furnace body 11. The lower front end of the outer furnace body 11 is fixedly connected to an air inlet groove 12. An air inlet cover plate 13 is slidably connected inside the air inlet groove 12. A slag discharge cover plate 14 is provided on the lower end of the outer furnace body 11. An insulation layer 15 is fixedly connected inside the outer furnace body 11. An inner furnace body 16 is fixedly connected inside the insulation layer 15.
[0024] Specifically, one piece of processed biomass fuel is lit and placed inside the inner furnace body 16. The remaining biomass fuel is then placed inside the inner furnace body 16, and the air vent cover 13 is opened to allow air to enter the lower part of the inner furnace body 16 to maintain the combustion of the biomass fuel. The pot is then placed on the upper end of the pot rack 5 for cooking.
[0025] Working principle:
[0026] First, ignite one piece of processed biomass fuel and place it inside the inner furnace body 16. Then, place the remaining biomass fuel inside the inner furnace body 16 and open the vent cover 13 to allow air to enter the lower part of the inner furnace body 16 to maintain the combustion of the biomass fuel. Then, place the pot on the upper end of the pot support leg 5 for cooking. After cooking, remove the limiting rods 33 on both sides. Due to gravity, the mesh plates 32 on both sides are forced to rotate, discharging the burnt residue into the bottom of the inner furnace body 16. Place the collection box under the ash discharge cover 14 and open the ash discharge cover. The slag cover plate 14 rotates the handle 24, which drives the rotating shaft 23 to rotate, and then drives the bevel gear 26 to rotate through the first bevel gear 25, which in turn drives the cutter 28 and the feeding auger 29 to rotate. The cutter 28 first cuts the larger waste slag, and the cut slag is evenly fed out of the inner furnace body 16 through the cutter 28 and falls into the collection box. The larger waste slag is first cut by the crushing mechanism 2 and then evenly fed out of the inner furnace body 16, which ensures that the larger slag will not get stuck at the discharge port at the lower end of the inner furnace body 16, and that dust will not be scattered during the slag discharge process, making it easy to collect the slag.
