Description

Technical Field

[0001] This utility model relates to the field of heating stove technology, and in particular to a heating stove for biomass pellets. Background Technology

[0002] In vast rural areas and other regions, especially in some relatively underdeveloped rural areas, pastoral areas, remote mountainous areas, and desert areas in Northwest, North, and Northeast my country, where transportation is inconvenient and there is little exchange with the outside world in terms of culture, awareness, science and technology, and economic information, people still use some very primitive and traditional methods for heating during the cold winter. They usually crush the crop straw from their own land into biomass pellets and then burn them in biomass stoves.

[0003] The existing patent publication number CN212029614U, entitled "A Biomass Pellet Heating Stove", proposes that this utility model can boil water and dry clothes while burning biomass fuel for heating, making it fully functional and making full use of energy. At the same time, the combustion exhaust gas can be discharged in time through the exhaust pipe, making it safer and healthier to use. The rack can not only dry clothes, but also effectively prevent people from directly contacting the combustion box and causing burns.

[0004] However, the bio-particle heater disclosed in the above patent requires opening the furnace door and using tools such as pliers to clean the ash during use. Since the heater does not stop burning at this time, there is a risk of flames spreading outwards and burning the user. Therefore, it is necessary to propose a bio-particle heater to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a biomass pellet heating stove to solve the problem mentioned in the background art that existing biomass pellet heating stoves require opening the stove door and using tools such as pliers to clean the ash during use. Since the stove does not stop burning at this time, there is a risk of flame leakage and burns to the user.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a biomass pellet heating stove, including a combustion chamber, an ash collection component fixedly installed at the bottom of the combustion chamber, a combustion chamber inside the combustion chamber, a placement frame installed inside the combustion chamber via a convenient component, and a combustion plate fixedly installed at the bottom of the placement frame;

[0007] The convenient component includes two sleeve rods respectively fixedly mounted on the front and rear sides of the placement frame. Two symmetrically distributed fixed rods are slidably arranged inside the sleeve rods. A partition plate is fixedly installed in the middle of the inside of the sleeve rod. A spring is fixedly connected between the end of the fixed rod inside the sleeve rod and the partition plate. The end of the fixed rod extending out of the sleeve rod is fixedly connected to the inner wall of the combustion chamber. A rotating shaft is rotatably arranged between the two fixed rods on the right side. A handle is fixedly installed at the end of the rotating shaft that moves through the rear side of the combustion chamber. Two cams are fixedly installed on the outer ring of the rotating shaft. The two cams are symmetrically distributed about the center line of the placement frame.

[0008] A scraping component is provided between the placement frame and the combustion chamber.

[0009] Preferably, the ash collection assembly includes an ash discharge box fixedly installed at the bottom of the combustion chamber, a dust collection box slidably installed inside the ash discharge box, a plurality of air inlets are opened at the upper end of the front side of the ash discharge box, and an ash discharge port communicating with the ash discharge box is opened at the bottom of the combustion chamber.

[0010] Preferably, a water tank is fixedly installed on the top of the combustion chamber, and an inlet pipe and an outlet pipe are fixedly installed on the left and right sides of the water tank, respectively, with a valve installed on the outlet pipe.

[0011] Preferably, the top of the incineration chamber is provided with a flue pipe, the upper end of which penetrates the top of the water tank.

[0012] Preferably, the ash scraping assembly includes a groove formed on the rear side of the combustion chamber, an ash scraping plate is movably attached to the upper surface of the combustion plate, an L-shaped rod is fixedly provided at the middle of the top of the ash scraping plate, and a push-pull plate is fixedly provided at one end of the L-shaped rod that movably passes through the groove.

[0013] Preferably, a baffle for covering the slide groove is fixedly provided on the surface of the push-pull plate, and the baffle is movably fitted to the rear side of the combustion chamber.

[0014] Preferably, the combustion chamber has a furnace door rotatably mounted on its front side, and an observation window is provided inside the furnace door. The ash discharge box has casters rotatably mounted at each of the four corners of its bottom, and foot brakes are provided on the casters.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. After a period of combustion, ash will accumulate on the combustion plate. At this time, turning the handle will drive the rotating shaft and cam to rotate. The cam will strike the placement frame, pushing the placement frame and sleeve rod to move. After the cam moves away from the placement frame, the placement frame and combustion plate will move in opposite directions under the elastic force of the spring. Repeating the above operation will make the placement frame and combustion plate vibrate back and forth, which will facilitate the ash on the combustion plate to fall into the dust collection box for collection. This will prevent the ash from affecting the complete combustion of the biomass pellets and solve the problem that existing biomass pellet heating stoves require opening the stove door and using tools such as pliers to clean the ash during use. Since the heating stove does not stop burning at this time, there is a risk of flame leakage and burns to the user.

[0017] 2. In this invention, biological pellets are placed inside the placement frame. After the biological pellets are ignited, the furnace door is closed. External gas enters the combustion chamber through the air inlet, and the flue gas is discharged through the exhaust pipe. The burning biological pellets not only have a heating effect, but also heat the water inside the water tank, thus enhancing the functionality of the device.

[0018] 3. When it is necessary to clean the furnace ash, the user turns the handle with one hand and pushes the push-pull plate to the reset position with the other hand, which moves the L-shaped rod and the scraper blade to the reset position. This allows the scraper blade to stir the furnace ash on the combustion plate, making it easier for all the furnace ash to fall into the dust collection box. At the same time, it can also stir the bio-particles, accelerate the combustion of the bio-particles, and improve the combustion efficiency of the device. Attached Figure Description

[0025] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides, for example Figures 1-5 The biomass pellet heating stove shown includes a combustion chamber 1, a furnace door 23 rotatably mounted on the front side of the combustion chamber 1, an observation window inside the furnace door 23, an ash collection component fixedly mounted at the bottom of the combustion chamber 1, a combustion chamber inside the combustion chamber 1, a placement frame 10 mounted inside the combustion chamber via a convenient component, a combustion plate 11 fixedly mounted at the bottom of the placement frame 10, a water tank 6 fixedly mounted on the top of the combustion chamber 1, an inlet pipe 7 and an outlet pipe 8 fixedly mounted on the left and right sides of the water tank 6 respectively, a valve mounted on the outlet pipe 8, and a flue pipe 9 mounted on the top of the combustion chamber, the upper end of the flue pipe 9 penetrating the top of the water tank 6.

[0027] The convenient component includes two sleeve rods 13 fixedly mounted on the front and rear sides of the placement frame 10, respectively. Two symmetrically distributed fixed rods 12 are slidably mounted inside the sleeve rods 13. A partition plate is fixedly mounted in the middle of the sleeve rods 13. A spring 14 is fixedly connected between the end of the fixed rod 12 inside the sleeve rod 13 and the partition plate. The end of the fixed rod 12 extending out of the sleeve rod 13 is fixedly connected to the inner wall of the combustion chamber 1. A rotating shaft 15 is rotatably mounted between the two fixed rods 12 on the right side. A handle 17 is fixedly mounted at one end of the rotating shaft 15 that moves through the rear side of the combustion chamber 1. Two cams 16 are fixedly mounted on the outer ring of the rotating shaft 15. The two cams 16 are symmetrically distributed about the center line of the placement frame 10.

[0028] The ash collection assembly includes an ash discharge box 2 fixedly installed at the bottom of the combustion chamber 1. A dust collection box 5 is slidably installed inside the ash discharge box 2. Several air inlets 4 are opened at the upper end of the front side of the ash discharge box 2. An ash drop port 3 connected to the ash discharge box 2 is opened at the bottom of the combustion chamber 1. Universal wheels are rotatably installed at the four corners of the bottom of the ash discharge box 2, and foot brakes are installed on the universal wheels.

[0029] Specifically, in this invention, biological pellets are placed inside the placement frame 10, and after the biological pellets are ignited, the furnace door 23 is closed. External gas enters the combustion chamber through the air inlet 4, and the flue gas is discharged through the exhaust pipe 9. The burning biological pellets not only have a heating effect, but also heat the water inside the water tank 6, thereby enhancing the functionality of the device.

[0030] After a period of combustion, ash will accumulate on the combustion plate 11. At this time, rotating the handle 17 will cause the rotating shaft 15 and cam 16 to rotate. The cam 16 will strike the placement frame 10, pushing the placement frame 10 and the sleeve rod 13 to move. After the cam 16 moves away from the placement frame 10, the placement frame 10 and the combustion plate 11 will move in opposite directions under the elastic force of the spring 14. Repeating the above operation will cause the placement frame 10 and the combustion plate 11 to vibrate back and forth, which will facilitate the ash on the combustion plate 11 to fall into the dust collection box 5 for collection. This will prevent the ash from affecting the complete combustion of the biomass pellets and solve the problem that existing biomass pellet heating stoves require opening the stove door 23 and using tools such as pliers to clean the ash during use. Since the heating stove does not stop burning at this time, there is a risk of flame leakage and burns to the user.

[0031] Furthermore, a scraping assembly is provided between the placement frame 10 and the combustion chamber 1. The scraping assembly includes a groove 18 opened on the rear side of the combustion chamber 1. A scraping plate 20 is movably attached to the upper surface of the combustion plate 11. An L-shaped rod 19 is fixedly provided at the middle of the top of the scraping plate 20. A push-pull plate 22 is fixedly provided at one end of the L-shaped rod 19 that movably passes through the groove 18. A baffle 21 for covering the groove 18 is fixedly provided on the surface of the push-pull plate 22. The baffle 21 is movably attached to the rear side of the combustion chamber 1.

[0032] When it is necessary to clean the furnace ash, the user turns the handle 17 with one hand and pushes the push-pull plate 22 to move back to the reset position with the other hand, which drives the L-shaped rod 19 and the scraper 20 to move back to the reset position. This allows the scraper 20 to stir the furnace ash on the combustion plate 11, so that all the furnace ash falls into the dust collection box 5. At the same time, it can stir the bio-particles, accelerate the combustion of the bio-particles, and improve the combustion efficiency of the device.

[0033] Working principle: This invention places biomass pellets inside the placement frame 10, ignites the biomass pellets, and closes the furnace door 23. External gas enters the combustion chamber through the air inlet 4, and flue gas is discharged through the exhaust pipe 9. The burning biomass pellets not only provide heating but also heat the water inside the water tank 6. After burning for a period of time, ash will accumulate on the combustion plate 11. At this time, the user turns the handle 17 with one hand, causing the rotating shaft 15 and cam 16 to rotate. The cam 16 strikes the placement frame 10, pushing the placement frame 10 and the sleeve rod 13 to move. After the cam 16 moves away from the placement frame 10, Under the elastic force of spring 14, the placement frame 10 and the combustion plate 11 are displaced in opposite directions. Repeating the above operation, the placement frame 10 and the combustion plate 11 vibrate back and forth, which makes it easier for the furnace ash on the combustion plate 11 to fall into the dust collection box 5 for collection. This ensures that the furnace ash will not affect the full combustion of the biomass pellets. The user's other hand pushes the push-pull plate 22 to move back to the reset position, which drives the L-shaped rod 19 and the scraper 20 to move back to the reset position. This allows the scraper 20 to stir the furnace ash on the combustion plate 11, making it easier for all the furnace ash to fall into the dust collection box 5. At the same time, it can stir the biomass pellets and accelerate their combustion.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
