Description
Technical Field
[0001] This invention relates to the field of boiler technology, and in particular to an electronically controlled constant temperature boiler and method that can use both biomass fuel and coal. Background Technology
[0002] Currently, coal is the most commonly used fuel for boilers. However, due to increasing energy scarcity and rising environmental demands driven by economic development and improved living standards, coal-fired emissions remain a long-term problem that requires resolution. Therefore, the demand for energy conservation and the use of biomass energy as a substitute for coal is becoming increasingly urgent.
[0003] In the prior art, for example, Chinese invention publication number CN202350105U relates to a boiler, and more particularly to a constant temperature boiler with electronic temperature control that can burn both biomass fuel and coal. It includes a boiler shell, an inner liner, a furnace, and a flue gas outlet. Its features are: on one side of the inner liner, a grate, a combustion chamber, and a feeding bin are arranged sequentially from bottom to top; on the other side, a transverse S-shaped furnace is formed by vertically staggered inner liner baffles; the rear of the boiler shell is provided with a water outlet, a water return outlet, a water inlet, and a drain outlet sequentially from top to bottom; a safety vent is provided at the top of the boiler shell; a furnace door is provided above the grate; and a primary air matching hole is provided above the grate and below the front wall of the feeding bin, extending into the furnace. Its unique structure can solve the problem that traditional boilers can only burn coal and not biomass fuel, and enables constant temperature operation of the boiler.
[0004] Since the waste residue from the combustion of biomass fuel can be reused as waste, the above-mentioned device is only equipped with one combustion chamber for combustion. That is, biomass fuel and coal fuel share the same combustion chamber, and the waste residue after combustion of the two cannot be separated separately, thus making it impossible to reuse. Summary of the Invention
[0005] The purpose of this invention is to provide an electronically controlled constant temperature boiler and method that can use both biomass fuel and coal, in order to solve the technical problem in the prior art where biomass fuel and coal fuel in the boiler share a combustion chamber, and the waste residue after combustion of both cannot be separated separately, thus making it impossible to reuse them.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: An electronically controlled constant-temperature boiler that can use both biomass fuel and coal includes: The boiler body has two combustion chambers, one fire-collecting chamber, and one water chamber inside. The water chamber is located at the top, and the fire-collecting chamber is located at the bottom of the water chamber. Both combustion chambers are located within the fire-collecting chamber. A branch channel is provided at the bottom center of the fire-collecting chamber, which is connected to the two combustion chambers respectively. A first rotating hole is provided on the inner wall of both sides of the confluence of the branch channels. A first rotating rod is rotatably installed inside the two first rotating holes. The first rotating rod is fixed with a baffle plate. A drive assembly is provided on the outer side of the boiler body. One end of the first rotating rod is connected to the drive assembly, and the drive assembly causes the first rotating rod to rotate axially. A discharge port is provided on one side of the outer wall of the combustion chamber, and an ash discharge port is provided on the bottom side of the outer wall of the combustion chamber. Two water pipes are fixed on both sides of the water chamber and connected to it. Two combustion boxes are slidably disposed in two branch channels respectively. The outer side wall of each combustion box has a notch aligned with the discharge port, and the bottom of each combustion box has multiple through holes. A jacking assembly is installed on the boiler body and located below the two combustion boxes. The jacking assembly causes the combustion boxes to move up and down reciprocally along the branch channel. Two air supply assemblies are provided, each located at the bottom of one of the two combustion chambers.
[0007] A further improvement of the present invention is that a material discharge box door is hinged to one side of the discharge port.
[0008] A further improvement of the present invention is that a ash discharge box door is hinged to one side of the ash discharge port.
[0009] A further improvement of the present invention is that a controller is installed on the outer wall of the boiler body, and a temperature sensor is installed inside the water cavity, and the temperature sensor is electrically connected to the controller.
[0010] A further improvement of the present invention is that the driving assembly includes an electric push rod, a first toothed plate, and a first gear. The electric push rod is fixed to the boiler body as a whole, one end of the electric push rod is fixed to the first toothed plate, the first gear is coaxially fixed to the first rotating rod, the first toothed plate meshes with the first gear, and the electric push rod is electrically connected to the controller.
[0011] A further improvement of the present invention is that the top-moving assembly includes a servo motor, a second rotating rod, and two cams. Second rotating holes are provided on both sides of the two combustion chambers. The entire second rotating rod is rotatably installed within the second rotating holes. The entire two cams are fixed to the second rotating rod, and the entire two cams respectively contact the bottom of the combustion chamber. The entire servo motor is fixed to the outside of the boiler body. The output shaft of the servo motor is coaxially fixed with the second rotating rod. The servo motor is electrically connected to the controller.
[0012] A further improvement of the present invention is that the air supply assembly includes a blower, and an air inlet pipe is provided between the output end of the blower and the combustion chamber to connect the two, and an electromagnetic regulating valve is installed on the air inlet pipe.
[0013] A further improvement of the present invention is that both the blower and the electromagnetic regulating valve are electrically connected to the controller.
[0014] A further improvement of the present invention is that a third rotating hole is provided on both outer walls of the combustion box, a rotating column is rotatably installed inside the two third rotating holes, a plurality of stirring plates are fixed on the outer side of the rotating column, a second gear is fixed on one end of the rotating column and coaxially arranged therewith, and a second toothed plate is fixed on the inner wall of the combustion chamber, the second toothed plate meshing with the second gear.
[0015] A method for using an electronically controlled constant-temperature boiler that can power both biomass fuel and coal includes: The two combustion chambers are used to burn coal and biomass fuel respectively, and waste residue is collected separately. The baffle is set to close one of the branch channels, so that the combustion chamber can work smoothly and independently. At the same time, the flame can enter the fire collection chamber to heat the water chamber. The combustion box is vibrated by the jacking component to shake off the dust and prevent the dust from adhering to the fuel and affecting combustion. During the up and down reciprocating vibration of the combustion box, the fuel is stirred, thereby increasing the contact area between the fuel and air and improving the combustion efficiency.
[0016] Compared with the prior art, the present invention has at least the following beneficial technical effects: This invention features a boiler with two independent combustion chambers, one for burning coal and the other for burning biomass fuel. This allows for separate collection of waste residue, facilitating recycling and reuse. The baffles are designed to close one branch channel, ensuring the combustion chamber operates independently while allowing flames to enter the heat collection chamber to heat the water chamber. A controller monitors the temperature and, to maintain a constant temperature, adjusts the airflow via an electromagnetic regulating valve, thereby controlling the degree of combustion.
[0017] Furthermore, the servo motor rotates axially via the second rotating rod, and the cam on the second rotating rod rotates. The cam continuously pushes the combustion box in contact with it, thereby causing the combustion box to vibrate, shaking off the dust and preventing the dust from adhering to the fuel and affecting combustion.
[0018] Furthermore, during the reciprocating vibration of the combustion chamber, the second gear and the second toothed plate on one end of the rotating column on the combustion chamber move relative to each other. The second toothed plate causes the second gear to rotate in both directions, and the second gear causes the rotating column to rotate in both directions. The stirring plate on the rotating column stirs the fuel, thereby increasing the contact area between the fuel and the air, thus improving the combustion efficiency. Attached Figure Description

[0030] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
[0031] Example 1 refer to Figure 1-4 The present invention provides an electronically controlled constant-temperature boiler that can use both biomass fuel and coal, comprising: The boiler body 1 has two combustion chambers, one fire-collecting chamber 15, and one water chamber 13 inside. The water chamber 13 is located at the top, and the fire-collecting chamber 15 is located at the bottom of the water chamber 13. Both combustion chambers are located in the fire-collecting chamber 15. A branch channel 18 is provided at the middle of the bottom of the fire-collecting chamber 15, which is connected to the two combustion chambers respectively. The inner walls on both sides of the confluence of the branch channels 18 are provided with first rotating holes. A first rotating rod 17 is rotatably installed inside the two first rotating holes. A baffle 16 is fixed to the entire first rotating rod 17. A drive assembly is provided on the outside of the boiler body 1. One end of the first rotating rod 17 is connected to the drive assembly, and the drive assembly causes the first rotating rod 17 to rotate axially. A discharge port is provided on one side of the outer wall of the combustion chamber. A discharge box door 2 is hinged to one side of the discharge port. An ash discharge port is provided on one side of the outer wall of the bottom of the combustion chamber. An ash discharge box door 3 is hinged to one side of the ash discharge port. Two water pipes 12 are fixed on both sides of the water chamber 13 and connected to it.
[0032] Two combustion boxes 19 are slidably disposed in two branch channels 18. The outer side wall of the combustion box 19 has a notch aligned with the discharge port, and the bottom of the combustion box 19 has multiple through holes.
[0033] The jacking assembly is installed on the boiler body 1 and located below the two combustion boxes 19. The jacking assembly causes the combustion boxes 19 to move up and down reciprocally along the branch channel 18.
[0034] Two air supply assemblies are provided, each located at the bottom of one of the two combustion chambers.
[0035] As can be seen from the above connection relationship, the entire boiler is equipped with two independent combustion chambers. The two combustion chambers are used to burn fuel coal and biomass fuel respectively. This allows for separate collection of waste residue, which is convenient for recycling and secondary use. At the same time, the baffle 16 is set to close one of the branch channels 18, so that the combustion chamber can work smoothly and independently. Meanwhile, the flame can enter the fire collection chamber 15 to heat the water chamber 13.
[0036] Specifically, a controller 4 is installed on the outer wall of the boiler body 1, and a temperature sensor 14 is installed inside the water chamber 13. The temperature sensor 14 is electrically connected to the controller 4. The air supply assembly includes a blower 8. An air inlet pipe 6 is provided between the output end of the blower 8 and the combustion chamber to connect the two. An electromagnetic regulating valve 7 is installed on the air inlet pipe 6. Both the blower 8 and the electromagnetic regulating valve 7 are electrically connected to the controller 4. As can be seen from the above connection relationship, in this scheme, the controller 4 is used to monitor the temperature. In order to maintain a constant temperature, the controller 4 adjusts the airflow through the electromagnetic regulating valve 7, thereby controlling the degree of combustion.
[0037] Specifically, the drive assembly includes an electric push rod 11, a first toothed plate 10, and a first gear 9. The electric push rod 11 is fixed to the boiler body 1. One end of the electric push rod 11 is fixed to the first toothed plate 10. The first gear 9 is coaxially fixed to the first rotating rod 17. The first toothed plate 10 meshes with the first gear 9. The electric push rod 11 is electrically connected to the controller 4.
[0038] As can be seen from the above connection relationship, in this scheme, the electric push rod 11 extends and retracts, thereby driving the first toothed plate 10 to move back and forth, the first gear 9 to rotate forward and backward, the first gear 9 causes the first rotating rod 17 to rotate forward and backward, and the first rotating rod 17 drives the baffle 16 to perform a reversing operation.
[0039] Specifically, the top-moving assembly includes a servo motor 5, a second rotating rod 22, and two cams 21. Second rotating holes are provided on both sides of the two combustion chambers. The entire second rotating rod 22 is rotatably installed within the second rotating hole. The entire two cams 21 are fixed to the second rotating rod 22, and the entire two cams 21 are in contact with the bottom of the combustion box 19. The entire servo motor 5 is fixed to the outside of the boiler body 1. The output shaft of the servo motor 5 is coaxially fixed with the second rotating rod 22. The servo motor 5 is electrically connected to the controller 4.
[0040] As can be seen from the above connection relationship, in this scheme, the servo motor 5 rotates axially through the second rotating rod 22, and the cam 21 on the second rotating rod 22 rotates. The cam 21 continuously pushes the combustion box 19 in contact with it, thereby causing the combustion box 19 to vibrate, shake off the dust, and prevent the dust from adhering to the fuel and affecting combustion.
[0041] Specifically, the outer walls of both sides of the combustion chamber 19 are provided with third rotating holes, and rotating columns are rotatably installed inside the two third rotating holes. Multiple stirring plates 20 are fixed on the outer side of the rotating columns, and a second gear 24 coaxially arranged with one end of the rotating columns is fixed. A second toothed plate 23 is fixed on the inner side wall of the combustion chamber, and the second toothed plate 23 meshes with the second gear 24. As can be seen from the above connection relationship, in this scheme, during the reciprocating vibration of the combustion box 19, the second gear 24 and the second toothed plate 23 on one end of the rotating column on the combustion box 19 move relative to each other. The second toothed plate 23 causes the second gear 24 to rotate in both directions, and the second gear 24 causes the rotating column to rotate in both directions. The stirring plate 20 on the rotating column stirs the fuel, thereby increasing the contact area between the fuel and the air, thereby improving the combustion efficiency.
[0042] Example 2 refer to Figure 1-4 The present invention provides a method for using an electronically controlled constant-temperature boiler that can use both biomass fuel and coal, comprising: The two combustion chambers are used to burn coal and biomass fuel respectively, and waste residue is collected separately. The baffle 16 is set to close one of the branch channels 18, so that the combustion chamber can work smoothly and independently. At the same time, the flame can enter the fire collection chamber 15 to heat the water chamber 13. The combustion box 19 is vibrated by the jacking component to shake off the dust and prevent the dust from adhering to the fuel and affecting combustion. During the up and down reciprocating vibration of the combustion box 19, the fuel is stirred, thereby increasing the contact area between the fuel and air and improving the combustion efficiency.
[0043] More specifically: The boiler has two independent combustion chambers, one for burning coal and the other for burning biomass fuel. This allows for separate collection of waste residue, facilitating recycling and reuse. The baffle 16 is designed to close one branch channel 18 (i.e., the electric push rod 11 extends and retracts, causing the first toothed plate 10 to move back and forth, which in turn causes the first gear 9 to rotate in both directions, which in turn causes the first rotating rod 17 to rotate in both directions, which in turn causes the baffle 16 to reverse direction). This allows the combustion chamber to operate independently while the flame can enter the fire-collecting chamber 15 to heat the water chamber 13. The controller 4 monitors the temperature and, to maintain a constant temperature, uses an electromagnetic regulating valve. 7. Adjust the airflow to control the degree of combustion; the servo motor 5 rotates axially via the second rotating rod 22, and the cam 21 on the second rotating rod 22 rotates. The cam 21 continuously pushes the combustion box 19 in contact with it, thereby causing the combustion box 19 to vibrate, shaking off the dust and preventing the dust from adhering to the fuel and affecting combustion; during the up-and-down reciprocating vibration of the combustion box 19, the second gear 24 and the second toothed plate 23 on one end of the rotating column on the combustion box 19 move relative to each other. The second toothed plate 23 causes the second gear 24 to rotate in both directions, and the second gear 24 causes the rotating column to rotate in both directions. The stirring plate 20 on the rotating column stirs the fuel, thereby increasing the contact area between the fuel and the air, thereby improving the combustion efficiency.
