Description

Technical Field

[0001] The invention relates to the technical field of biomass furnaces, in particular to an energy-saving biomass furnace. Background Art

[0002] The biomass melting furnace is a professional energy-saving and environmentally friendly melting furnace that uses bioenergy. It uses a crucible for melting and heat preservation. It is mainly used for melting or smelting low-melting-point non-ferrous metals and alloys such as aluminum, zinc, lead, tin, and cadmium. It is generally equipped with a die-casting machine and can also be used for aluminum liquid insulation, degassing, and refining. It has the characteristics of high efficiency and energy saving, low carbon and environmental protection, and simple operation and maintenance. It is the best product to replace fuel oil, gas, coke furnace, and electric furnace, and can reduce energy consumption costs.

[0003] The existing biomass furnace requires a spiral feeder and a blower for normal feeding, which increases the cost. The biomass furnace puts biomass particles into the combustion area at the feed port. When more and more particles flow into the combustion area, improper control of the feed speed will cause the particles to pile up together, resulting in insufficient combustion and reduced fuel utilization. As the burning time goes by, the outer surface of the crucible will be adhered to pot ash caused by combustion. If it is not cleaned in time, the pot ash will increase over time, causing the outer surface of the crucible to be insufficiently heated, which reduces the heat conduction efficiency and further reduces the efficiency of the furnace.

[0004] To this end, an energy-saving biomass furnace is proposed. Summary of the invention

[0005] The purpose of the present invention is to provide an energy-saving biomass melting furnace, which uses blades to control the feeding speed to prevent excessive feeding from causing particles to accumulate into agglomerates, resulting in incomplete combustion and further reducing the energy consumption rate. The fourth rotating shaft is used to rotate to drive the scraper rod to rotate. During the rotation of the scraper rod, the scraper rod will scrape off the ash attached to the outer surface of the crucible. This makes the outer surface of the crucible from which the ash is scraped off have a wider contact area with the burning fire source and is fully heated, thereby improving the heat conduction efficiency, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an energy-saving biomass furnace, comprising a furnace body, a crucible is movably installed at the middle position of the internal upper end of the furnace body, a chimney is fixedly installed on the upper end outer surface of the furnace body near the rear end, a discharge port is provided on the upper end outer surface of the furnace body near the right side, a vent is provided on the front end outer surface of the furnace body, a first rotating shaft is rotatably installed at the internal lower end of the furnace body near the right side, blades are fixedly installed on the outer surface of the first rotating shaft, and the number of blades is four groups, and the interior of the furnace body is located below the first rotating shaft and rotates A second rotating shaft is installed, a stepper motor is fixedly installed on the outer surface of the rear end of the furnace body, and the stepper motor is rotatably installed between the second rotating shaft, a belt is rotatably installed between the first rotating shaft and the second rotating shaft near the front end, a third rotating shaft is rotatably installed at the inner lower end of the furnace body near the left side, a conveyor belt is rotatably installed between the third rotating shaft and the second rotating shaft, a first gear is fixedly installed on the outer surface of the conveyor belt near the front end, a fan is rotatably installed on the inner surface of the front end of the furnace body corresponding to the ventilation port, a second gear is fixedly installed on the outer side of the fan, and a collecting box is provided inside the conveyor belt.

[0007] First, turn on the stepper motor and put the biomass particles into the discharge port. The second shaft rotates counterclockwise under the power provided by the stepper motor. The counterclockwise rotation of the second shaft drives the belt and the conveyor belt to rotate counterclockwise. The rotation of the belt drives the first shaft to rotate counterclockwise. The blades also rotate counterclockwise with the rotation of the first shaft. In this way, when the particles fall onto the conveyor belt, the conveyor belt will transport the particles to the left. The particles will be burned during the transportation process. In this process, the blades are used to control the feeding speed to prevent excessive feeding from causing the particles to accumulate into agglomerates, resulting in incomplete combustion and reducing the energy consumption rate. At the same time, the first gear rotates with the rotation of the conveyor belt. The first gear will drive the fan to rotate during the rotation process, and the wind will enter from the vent, which does not require a blower to provide sufficient oxygen for combustion, and the small air volume is not easy to generate dust, which improves the combustion efficiency while reducing costs. The smoke generated during the combustion process comes out through the chimney, and the generated ash passes through the conveyor belt into the collection box.

[0008] Preferably, a fourth rotating shaft is rotatably installed at the center of the outer surface of the lower end of the crucible, a scraper rod is fixedly installed on the outer surfaces of both sides of the fourth rotating shaft near the upper end, a fixing ring is fixedly installed on the outer surface of the fourth rotating shaft near the lower end, and teeth are fixedly installed on the edge of the outer surface of the lower end of the fixing ring.

[0009] When the crucible has been used for a long time, a lot of soot will adhere to the outer surface of the crucible. The soot makes the outer surface of the crucible insufficiently heated, which reduces the heat conduction efficiency. During the rotation of the fan, the second gear also rotates accordingly. The rotation of the second gear drives the teeth to rotate. The fixed ring rotates with the rotation of the teeth. The rotation of the fixed ring drives the fourth shaft to rotate. The rotation of the fourth shaft drives the ash scraping rod to rotate. During the rotation of the ash scraping rod, the ash scraping rod will scrape off the soot attached to the outer surface of the crucible. This makes the contact surface between the outer surface of the crucible from which the soot is scraped off and the burning fire source wider and more fully heated, thereby improving the heat conduction efficiency.

[0010] Preferably, the second gear is meshed with the first gear, the teeth are meshed with the second gear, the scraper rod is an arc-shaped structure, and the upper end outer surface of the scraper rod is in contact with the arc surface of the crucible.

[0011] In order to enable the first gear to drive the fan to rotate during the rotation process, the second gear is meshed with the first gear, and in order to enable the rotation of the second gear to drive the teeth to rotate, the teeth are meshed with the second gear, and in order for the ash scraping rod to scrape off the ash attached to the outer surface of the crucible, the ash scraping rod is configured as an arc structure, and the upper end outer surface of the scraping rod is in contact with the arc surface of the crucible.

[0012] Preferably, the outer surface of the conveyor belt is a mesh structure composed of crisscrossing metal wires, and a cam is fixedly mounted on the right outer surface of the third rotating shaft.

[0013] During the slow conveyance of the biomass particles on the conveyor belt, they will be burned. Part of the ash after burning will pass through the mesh structure on the conveyor belt and enter the collection box, and the remaining ash will remain on the mesh structure on the upper surface of the conveyor belt, which will clog the conveyor belt over time and reduce the combustion effect. When the third shaft is rotating, the cam on the third shaft also rotates. When the cam rotates, when the protruding part of the cam contacts the inner surface of the conveyor belt, it will squeeze the mesh structure on the conveyor belt. The mesh structure will vibrate up and down under the squeezing force of the cam, and the remaining ash on the conveyor belt will fall into the collection box under the vibration of the mesh structure, thereby improving the combustion effect.

[0014] Preferably, a first slide is obliquely fixedly installed on the left inner surface of the furnace body above the conveyor belt, and the right end of the first slide extends to the upper outer surface of the conveyor belt. A second slide is fixedly installed on the upper end of the first slide near the front and rear ends, and the right end of the second slide extends above the conveyor belt.

[0015] During the transportation of biomass particles on the conveyor belt, particles that are not burned or not fully burned will continue to be transported to the left. The right end of the first slide extends to the outer surface of the upper end of the conveyor belt, ensuring that the particles transported to the left will gradually move to the inclined surface of the first slide. At this time, when the particles on the inclined surface of the first slide move to a position on the inclined surface, they will stop moving to the left, and move along the second slide to the combustion place under the action of gravity to be burned, thereby improving the energy consumption rate of the particles.

[0016] Preferably, the inclined installation angle of the first slide is 15 degrees.

[0017] In order to ensure that the unburned and insufficiently burned particles are further transferred to the left onto the inclined surface of the first slide and then move along the second slide, the inclined angle of the inclined installation of the first slide is set to 15 degrees.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. Use blades to control the feeding speed to prevent excessive feeding from causing particles to accumulate into agglomerates, resulting in incomplete combustion and further reducing energy consumption;

[0020] 2. The ash scraping rod is driven to rotate by the rotation of the fourth rotating shaft. During the rotation of the ash scraping rod, the ash scraping rod will scrape off the soot attached to the outer surface of the crucible, so that the outer surface of the crucible from which the soot is scraped off has a wider contact surface with the burning fire source and is fully heated, thereby improving the heat conduction efficiency;

[0021] 3. With the cooperation of the first slide, the second slide and the conveyor belt, the biomass particles are moved along the second slide to the combustion site under the action of gravity and burned, thereby improving the energy consumption rate of the particles.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figures 1 to 5 , the present invention provides a technical solution:

[0030] An energy-saving biomass furnace, such as Figures 1 to 4 As shown, it includes a furnace body 1, a crucible 10 is movably installed at the middle position of the internal upper end of the furnace body 1, a chimney 16 is fixedly installed on the upper end outer surface of the furnace body 1 near the rear end, a discharge port 11 is opened on the upper end outer surface of the furnace body 1 near the right side, a vent 12 is opened on the front end outer surface of the furnace body 1, a first rotating shaft 3 is rotatably installed at the internal lower end of the furnace body 1 near the right side, blades 31 are fixedly installed on the outer surface of the first rotating shaft 3, and the number of blades 31 is four groups, a second rotating shaft 5 is rotatably installed below the first rotating shaft 3 in the interior of the furnace body 1, and the furnace body A stepper motor 2 is fixedly mounted on the outer surface of the rear end of the furnace body 1, and the stepper motor 2 is rotatably mounted between the second rotating shaft 5. A belt 4 is rotatably mounted between the first rotating shaft 3 and the second rotating shaft 5 near the front end. A third rotating shaft 7 is rotatably mounted at the lower end of the furnace body 1 near the left side. A conveyor belt 6 is rotatably mounted between the third rotating shaft 7 and the second rotating shaft 5. A first gear 61 is fixedly mounted on the outer surface of the conveyor belt 6 near the front end. A fan 8 is rotatably mounted on the inner surface of the front end of the furnace body 1 corresponding to the position of the vent 12. A second gear 81 is fixedly mounted on the outer side of the fan 8. A collecting box 13 is provided inside the conveyor belt 6.

[0031] When working, first turn on the stepper motor 2, put the biomass particles into the discharge port 11, and the second rotating shaft 5 rotates counterclockwise under the power provided by the stepper motor 2. The counterclockwise rotation of the second rotating shaft 5 drives the belt 4 and the conveyor belt 6 to rotate counterclockwise. The rotation of the belt 4 drives the first rotating shaft 3 to rotate counterclockwise, and the blade 31 also rotates counterclockwise with the rotation of the first rotating shaft 3. In this way, when the particles fall onto the conveyor belt 6, the conveyor belt 6 will convey the particles to the left, and the particles will be burned during the conveying process. In this process, the blade 31 is used to control the feeding speed to prevent excessive feeding from causing the particles to accumulate into agglomerates, resulting in incomplete combustion, and preventing the energy consumption rate from being reduced. At the same time, the first gear 61 rotates with the rotation of the conveyor belt 6. The first gear 61 will drive the fan 8 to rotate during the rotation, and the wind enters from the vent 12, which does not require a blower to provide sufficient oxygen for combustion, and the small air volume is not easy to generate dust, which improves the combustion efficiency while reducing costs. The smoke generated during the combustion process comes out through the chimney 16, and the generated ash passes through the conveyor belt 6 into the collection box 13.

[0032] As an embodiment of the present invention, Figure 2 and Figure 5 As shown, a fourth rotating shaft 9 is rotatably mounted at the center of the outer surface of the lower end of the crucible 10, and a scraper rod 92 is fixedly mounted on the outer surfaces of both sides of the fourth rotating shaft 9 near the upper end, and a fixing ring 91 is fixedly mounted on the outer surface of the fourth rotating shaft 9 near the lower end, and a tooth 93 is fixedly mounted on the edge of the outer surface of the lower end of the fixing ring 91, and the second gear 81 is meshed with the first gear 61, and the tooth 93 is meshed with the second gear 81, and the scraper rod 92 is an arc structure, and the upper outer surface of the scraper rod 92 contacts the arc surface of the crucible 10;

[0033] During operation, when the crucible 10 is used for a long time, a lot of soot will adhere to the outer surface of the crucible 10. The soot makes the outer surface of the crucible 10 insufficiently heated, which reduces the heat conduction efficiency. During the rotation of the fan 8, the second gear 81 also rotates, and the rotation of the second gear 81 drives the teeth 93 to rotate. The fixing ring 91 rotates with the rotation of the teeth 93. The rotation of the fixing ring 91 drives the fourth shaft 9 to rotate. The rotation of the fourth shaft 9 drives the scraping rod 92 to rotate. During the rotation of the scraping rod 92, the scraping rod 92 will scrape the soot attached to the outer surface of the crucible 10. The ash is scraped off, which makes the outer surface of the crucible 10 whose ash is scraped off and the contact surface of the burning fire source wider and more fully heated, thereby improving the heat conduction efficiency. In order to make the first gear 61 drive the fan 8 to rotate during the rotation process, the second gear 81 is meshed with the first gear 61. In order to make the second gear 81 rotate and drive the teeth 93 to rotate, the teeth 93 are meshed with the second gear 81. In order to make the scraping rod 92 scrape off the ash attached to the outer surface of the crucible 10, the scraping rod 92 is configured as an arc structure, and the upper end outer surface of the scraping rod 92 contacts the arc surface of the crucible 10.

[0034] As an embodiment of the present invention, Figure 4 and Figure 5 As shown, the outer surface of the conveyor belt 6 is a mesh structure and is composed of crisscrossed metal wires, and a cam 71 is fixedly mounted on the right outer surface of the third rotating shaft 7;

[0035] During operation, the biomass particles will be burned during the slow transmission on the conveyor belt 6. Part of the ash after combustion will pass through the mesh structure on the conveyor belt 6 and enter the collecting box 13, and the remaining ash will remain on the mesh structure on the upper surface of the conveyor belt 6, which will block the conveyor belt 6 over time, resulting in reduced combustion efficiency. When the third rotating shaft 7 is rotating, the cam 71 on the third rotating shaft 7 also rotates accordingly. When the cam 71 rotates, when the protruding part of the cam 71 contacts the inner surface of the conveyor belt 6, it will squeeze the mesh structure on the conveyor belt 6. The mesh structure will vibrate up and down under the squeezing force of the cam 71, and the remaining ash on the conveyor belt 6 will fall into the collecting box 13 under the vibration of the mesh structure, thereby improving the combustion effect.

[0036] As an embodiment of the present invention, Figure 4 and Figure 5 As shown, the left inner surface of the furnace body 1 is located above the conveyor belt 6 and a first slide 14 is fixedly installed at an angle, and the right end of the first slide 14 extends to the upper outer surface of the conveyor belt 6. The upper end of the first slide 14 is fixedly installed with a second slide 15 near the front and rear ends, and the right end of the second slide 15 extends above the conveyor belt 6. The first slide 14 is installed at an angle of 15 degrees.

[0037] During operation, the biomass particles that are not burned or not fully burned during the transportation on the conveyor belt 6 will continue to be transported to the left. The right end of the first slide 14 extends to the outer surface of the upper end of the conveyor belt 6 to ensure that the particles transported to the left will move to the inclined surface of the first slide 14 one after another. At this time, when the particles on the inclined surface of the first slide 14 move to a position on the inclined surface, they will stop moving to the left, and move along the second slide 15 to the combustion position under the action of gravity to be burned, thereby improving the energy consumption rate of the particles. In order to ensure that the particles that are not burned or not fully burned will continue to be transported to the left to the inclined surface of the first slide 14 and then move along the second slide 15, the inclination angle of the inclined installation of the first slide 14 is set to 15 degrees.

[0038] Working principle:

[0039] When working, first turn on the stepper motor 2, put the biomass particles into the discharge port 11, and the second shaft 5 rotates counterclockwise under the power provided by the stepper motor 2. The counterclockwise rotation of the second shaft 5 drives the belt 4 and the conveyor belt 6 to rotate counterclockwise. The rotation of the belt 4 drives the first shaft 3 to rotate counterclockwise. The blade 31 also rotates counterclockwise with the rotation of the first shaft 3. In this way, when the particles fall onto the conveyor belt 6, the conveyor belt 6 will convey the particles to the left. The particles will be burned during the conveying process. In this process, the blade 31 is used to control the feeding speed to prevent excessive feeding from causing the particles to accumulate into agglomerates, resulting in incomplete combustion, thereby reducing the energy consumption rate. At the same time, the first gear 61 rotates with the rotation of the conveyor belt 6, and the first gear 61 will drive the fan during the rotation. 8 rotates, and wind enters from the vent 12, which can provide sufficient oxygen for combustion without a blower, and the small air volume is not easy to generate dust, which improves the combustion efficiency and reduces the cost at the same time. The smoke generated during the combustion process comes out through the chimney 16, and the generated soot passes through the conveyor belt 6 and enters the collection box 13. When the crucible 10 is used for a long time, a lot of soot will adhere to the outer surface of the crucible 10, and the soot makes the outer surface of the crucible 10 insufficiently heated, which reduces the heat conduction efficiency. During the rotation of the fan 8, the second gear 81 also rotates, and the rotation of the second gear 81 drives the teeth 93 to rotate, and the fixing ring 91 rotates with the rotation of the teeth 93, and the rotation of the fixing ring 91 drives the fourth shaft 9 to rotate, and the rotation of the fourth shaft 9 drives the ash scraping rod 9 2 rotates, and during the rotation of the scraper rod 92, the scraper rod 92 will scrape off the soot attached to the outer surface of the crucible 10, so that the outer surface of the crucible 10 from which the soot is scraped off and the contact surface of the fire source are more widely heated, thereby improving the heat conduction efficiency. In order to make the first gear 61 drive the fan 8 to rotate during the rotation process, the second gear 81 is meshed with the first gear 61, and in order to make the second gear 81 rotate and drive the teeth 93 to rotate, the teeth 93 are meshed with the second gear 81, and in order to make the scraper rod 92 scrape off the soot attached to the outer surface of the crucible 10, the scraper rod 92 is set to an arc structure, and the outer surface of the upper end of the scraper rod 92 contacts the arc surface of the crucible 10, and the biomass particles will be burned during the slow transmission process on the conveyor belt 6, and the burned biomass particles will be burned. Part of the ash passes through the mesh structure on the conveyor belt 6 and enters the collecting box 13, and the remaining ash will remain on the mesh structure on the upper surface of the conveyor belt 6, which will block the conveyor belt 6 over time, resulting in reduced combustion efficiency. When the third rotating shaft 7 is rotating, the cam 71 on the third rotating shaft 7 also rotates accordingly. When the protruding part of the cam 71 contacts the inner surface of the conveyor belt 6 during the rotation of the cam 71, it will squeeze the mesh structure on the conveyor belt 6. The mesh structure will vibrate up and down under the squeezing force of the cam 71. The ash remaining on the conveyor belt 6 falls into the collecting box 13 under the vibration of the mesh structure, thereby improving the combustion efficiency. The biomass particles that are not burned or not fully burned during the transmission on the conveyor belt 6 will continue to be transmitted to the left.The right end of the first slide 14 extends to the outer surface of the upper end of the conveyor belt 6, ensuring that the particles conveyed to the left will gradually move to the inclined surface of the first slide 14. At this time, when the particles on the inclined surface of the first slide 14 move to a position on the inclined surface, they will stop moving to the left and move along the second slide 15 to the combustion site under the action of gravity to be burned, thereby improving the energy consumption rate of the particles.
