Description

Technical Field

[0001] This invention belongs to the field of energy-saving combustion engine technology, specifically an energy-saving biomass gas combustion engine. Background Technology

[0002] With the depletion of global conventional fossil fuel reserves and the intensification of environmental pollution, the development and utilization of clean and renewable biomass energy has become an important way to solve the energy crisis and environmental problems. As a carbon-neutral renewable energy source, biomass energy is widely available and has low pollution emissions. Its combustion utilization technology has received widespread attention in fields such as industrial heating and residential heating. As the core equipment for efficient conversion of biomass energy, the performance optimization of biomass gas burners is of key significance to promoting the development of the biomass energy industry. Existing burners have simple ash removal structures, ash is easy to accumulate and unburned materials cannot be recovered. In addition, the connection between the fan and the spiral feed port lacks an effective anti-backflow structure, and high-temperature airflow and materials are easy to backflow into the pipeline, causing raw material waste, pipeline blockage and safety hazards, which restricts energy utilization efficiency and operational stability.

[0003] Publication No. CN118499766A discloses an energy-saving biomass boiler burner, comprising: a base, a box fixedly installed on one side of the top of the base, a collection shell fixedly installed on the other side of the top of the base, a combustion furnace fixedly installed on the top of the collection shell, and a cleaning mechanism inside the collection shell. A power mechanism drives a straight groove plate to rotate, and uses an arc-shaped toothed block to mesh with a rack, causing the racks on both sides to move away from each other. The moving rod is then moved by the connecting plate to stretch a spring, thereby causing the two crushed blocks to move away from each other. When the arc-shaped toothed block is not meshing with the rack, the two crushed blocks move closer to each other and reset under the action of the spring. Therefore, in the process of the two crushed blocks moving closer and further away from each other, the effect of squeezing and crushing larger particles stuck on the screen can be achieved, effectively improving the completeness and stability of combustion of the burner.

[0004] This device can crush larger particles stuck on the screen by squeezing them as the two crushing blocks move closer and further apart. However, it still cannot prevent backflow between the blower and the screw feed inlet, and it cannot effectively recover ash and unburned materials. Therefore, an energy-saving biomass gas burner is proposed, which can accurately feed materials, efficiently clean ash, and prevent backflow, thereby improving the efficiency of biomass energy utilization, reducing operating costs, and ensuring the safe and stable operation of the equipment.

[0011] Preferably, a baffle is fixed to the bottom end of the second connecting rod, a transmission gear is fixed to the outside of the second connecting rod, a rack plate is slidably connected inside the control box, a buffer spring is fixed to the outside of the rack plate, and a piston column is fixed to one end of the buffer spring.

The transmission gear meshes with the rack plate, and with the elastic buffer of the buffer spring, the degree of opening and closing of the baffle can be precisely adjusted to control the gas-solid mixing ratio, ultimately achieving the effect of preventing backflow of airflow and optimizing the combustion ratio.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1 to 6 As shown, the present invention provides an energy-saving biomass gas burner, including a base 1, a combustion cylinder 2 fixed to the top of the base 1, a conveying pipe 3 fixed to the outside of the combustion cylinder 2, a fan 4 fixed to the top of the base 1, a feed cylinder 5 fixed to the top of the conveying pipe 3, a feeding mechanism 6 fixed to the top of the feed cylinder 5, a recycling box 7 slidably connected inside the base 1, an energy-saving mechanism 8 installed outside the conveying pipe 3, and an ignition rod 9 fixed inside the combustion cylinder 2.

[0022] like Figures 1 to 5 As shown, the feeding mechanism 6 includes a first servo motor 601, a spiral conveying rod 602, and a first bevel gear 603. The first servo motor 601 is fixed to the top of the feeding cylinder 5. The spiral conveying rod 602 is fixed to the drive end of the first servo motor 601. The first bevel gear 603 is fixed to the bottom end of the spiral conveying rod 602. A first connecting rod 604 is rotatably connected inside the base 1. A second bevel gear 605 is fixed to the outside of the first connecting rod 604. The outer wall of the spiral conveying rod 602 is attached to the inner wall of the conveying pipe 3. The spiral conveying rod 602 and the conveying pipe 3 are rotatably connected. The outer wall of the first bevel gear 603 is provided with several sets of teeth. The outer wall of the second bevel gear 605 is provided with several sets of teeth. The first bevel gear 603 and the second bevel gear 605 are meshed together.

[0023] like Figures 1 to 5As shown, an eccentric wheel 606 is fixed to the outside of the first connecting rod 604, and a filter disk 607 is slidably connected inside the base 1. The top of the filter disk 607 is provided with filter holes 608. Two sets of eccentric wheels 606 are provided, and the eccentric wheels 606 are symmetrically distributed about the central axis of the filter disk 607. The outer wall of the filter disk 607 is attached to the inner wall of the combustion cylinder 2. The top of the filter disk 607 is provided with an arc surface. Several sets of filter holes 608 are provided, and the filter holes 608 are distributed in a ring array about the central axis of the filter disk 607.

[0024] The above scheme is adopted as follows: After the material is poured into the inside of the feeding cylinder 5, the first servo motor 601 is started to drive the spiral conveyor rod 602 to rotate, and then the material is conveyed through the spiral conveyor rod 602 to enter the inside of the combustion cylinder 2 through the conveying pipe 3. Then the ignition rod 9 is started to burn. When the spiral conveyor rod 602 rotates, it drives the first bevel gear 603 to rotate synchronously. The rotation of the first bevel gear 603 drives the second bevel gear 605, the first connecting rod 604 and the eccentric wheel 606 to rotate. When the eccentric wheel 606 rotates, it continuously squeezes and disengages from the ash filter disc 607, thereby causing the ash filter disc 607 to shake. Through the shaking, the burning dust falls into the inside of the recycling box 7 through the filter hole 608.

[0025] like Figures 1 to 6 As shown, the energy-saving mechanism 8 includes a control box 801, a second servo motor 802, and a second connecting rod 803. The control box 801 is fixed to the top of the conveying pipe 3. The second servo motor 802 is fixed to the top of the control box 801. The second connecting rod 803 is fixed to the drive end of the second servo motor 802. The outer wall of the second connecting rod 803 is attached to the inner wall of the control box 801. The second connecting rod 803 and the control box 801 are rotatably connected. The outer wall of the second connecting rod 803 is attached to the outer wall of the conveying pipe 3. The second connecting rod 803 and the conveying pipe 3 are rotatably connected. A baffle 804 is fixed to the bottom of the second connecting rod 803. A transmission gear 805 is fixed to the outside of the second connecting rod 803. A rack plate is slidably connected inside the control box 801. 806, the outer diameter of the baffle 804 is equal to the inner diameter of the conveying pipe 3. Several sets of teeth are fixed on the outside of the transmission gear 805. The transmission gear 805 and the rack plate 806 are meshed and connected. A buffer spring 807 is fixed on the outside of the rack plate 806. A piston column 808 is fixed at one end of the buffer spring 807. There are two sets of transmission gears 805 and two sets of rack plates 806. The rack plates 806 are symmetrically distributed about the central axis of the second connecting rod 803. Several sets of buffer springs 807 are arranged in a ring array about the central axis of the rack plate 806. The buffer springs 807 are used to squeeze the rack plate 806. The outer wall of the piston column 808 is attached to the inner wall of the control box 801. The piston column 808 and the control box 801 are slidably connected.

[0026] The above solution is adopted: by starting the second servo motor 802, the second connecting rod 803 and the baffle 804 are rotated, and the internal channel of the conveying pipe 3 is opened and closed by the rotation of the baffle 804. The buffer spring 807 squeezes the rack plate 806 to buffer the transmission gear 805, and thus buffer the baffle 804. When the ignition is not complete and the fan 4 is off, the internal channel of the conveying pipe 3 is closed by the baffle 804, which can prevent biomass raw materials from entering the pipeline of the fan 4 due to airflow turbulence in the early stage of conveying, thereby reducing raw material waste and pipeline accumulation.

[0027] The working principle and usage process of this invention are as follows: First, after the material is poured into the inside of the feeding cylinder 5, the first servo motor 601 is started to drive the spiral conveyor rod 602 to rotate. Then, the spiral conveyor rod 602 conveys the material, which enters the inside of the combustion cylinder 2 through the conveying pipe 3. Then, the ignition rod 9 is started to ignite. When the spiral conveyor rod 602 rotates, it drives the first bevel gear 603 to rotate. The rotation of the first bevel gear 603 drives the second bevel gear 605, the first connecting rod 604 and the eccentric wheel 606 to rotate. When the eccentric wheel 606 rotates, it continuously squeezes and disengages from the ash filter disc 607, which causes the ash filter disc 607 to shake. The shaking causes the burning ash to fall into the inside of the recovery box 7 through the filter holes 608, thereby recovering the ash. It can also drive the unburned material to vibrate upward, bringing it closer to the fire source and improving the combustion efficiency. The vibration starts and stops with the feeding. When the vibration occurs, the material inside the combustion cylinder 2 is in a state where it is about to burn out.

[0028] Secondly, by starting the second servo motor 802, the second connecting rod 803 and the baffle 804 are rotated. The rotation of the baffle 804 opens and closes the internal channel of the conveying pipe 3. The buffer spring 807 presses the rack plate 806 to buffer the transmission gear 805, which in turn buffers the baffle 804. When the device is not ignited and the blower 4 is off, the baffle 804 closes the inside of the conveying pipe 3, which can prevent biomass raw materials from entering the pipe of the blower 4 due to airflow turbulence in the early stage of conveying, thus reducing raw material waste and pipe accumulation. When the device is started, the second servo motor 802 controls the opening and closing degree of the baffle 804, thereby adjusting the elastic preload of the two sets of buffer springs 807. This can precisely control the airflow entering the conveying pipe 3, allowing the biomass raw materials and airflow to form a more reasonable gas-solid mixture state and enter the interior of the combustion chamber 2.

[0029] After the baffle 804 is closed, the material pushed by the first servo motor 601 and the screw conveyor 602 will form a stable pre-storage area in the conveying pipe 3 section between the baffle 804 and the screw conveyor 602. This pre-storage area can prevent the material from being dispersed and accumulated due to the lack of obstruction. After the ignition rod 9 is successfully ignited and the fan 4 is started to the rated power, the baffle 804 is opened by the second servo motor 802. This allows the material in the pre-storage area to enter the combustion chamber 2 in a uniform and continuous manner, ensuring the stability of the subsequent combustion process and avoiding flame fluctuations caused by intermittent feeding.

[0030] When not ignited, the inside of the combustion chamber 2 is at room temperature and needs to be pre-ventilated through the fan 4 pipe. After the baffle 804 is closed, it can form a physical isolation barrier to prevent dust, moisture and other impurities in the external environment from entering the conveying pipe 3 and the feed cylinder 5 in the reverse direction through the fan 4 pipe. This can prevent biomass raw materials from getting damp and clumping, and at the same time prevent impurities from mixing into the raw materials and affecting the combustion efficiency, ensuring the dryness and cleanliness of the raw materials, and ensuring the stability of the calorific value of the raw materials during combustion.

[0031] During the combustion process of the material in the combustion chamber 2, the vibration of the ash filter disc 607 is linked to the feeding action of the screw conveyor 602. When the screw conveyor 602 stops feeding, the first bevel gear 603 stops rotating along with the screw conveyor 602, and the second bevel gear 605, the first connecting rod 604, and the eccentric wheel 606 stop moving synchronously. The ash filter disc 607 stops vibrating. When the screw conveyor 602 starts feeding again, the ash filter disc 607 starts vibrating again. This linkage design ensures that the ash filter disc 607 only vibrates and cleans the ash when the material in the combustion chamber 2 produces ash and slag, avoiding ineffective vibration in the absence of ash and slag, reducing equipment energy consumption, and reducing frictional wear between the ash filter disc 607 and the inner wall of the combustion chamber 2, thus extending the service life of the components.

[0032] The arc-shaped structure at the top of the ash filter disc 607 guides unburned material to gather towards the center of the combustion chamber 2 during vibration, making it easier for it to approach the ignition source generated by the ignition rod 9, thus improving the secondary combustion efficiency of the unburned material. Several sets of annularly distributed filter holes 608 ensure that the ash falls evenly, avoiding the problem of incomplete ash removal caused by blockage of a single filter hole. The recycling box 7 is slidably connected to the base 1. When the ash in the recycling box 7 reaches the preset amount, the recycling box 7 can be directly pulled out for ash cleaning or recycling. The operation is convenient, without the need to disassemble the equipment, reducing maintenance time.

[0033] During the adjustment of the opening and closing degree of the baffle 804, the buffer spring 807 generates a continuous compressive force on the rack plate 806 through its own elastic deformation. This compressive force is transmitted to the second connecting rod 803 through the meshing transmission of the rack plate 806 and the transmission gear 805, thereby buffering the rotational movement of the baffle 804. When the baffle 804 reaches the target opening and closing angle, the elastic preload of the buffer spring 807 can fix the relative position of the rack plate 806 and the transmission gear 805, avoiding the angle deviation of the baffle 804 caused by the airflow impact generated by the fan 4, and ensuring the accuracy of airflow control. At the same time, the ring array distribution design of the buffer spring 807 can make the rack plate 806 bear the force evenly, avoiding the rack plate 806 from jamming or deformation caused by unilateral force, and ensuring the smoothness of the adjustment movement of the baffle 804.

[0034] After the blower 4 starts, the outside air is pressurized by the blower 4 and enters the conveying pipe 3. It mixes with the biomass raw materials conveyed by the screw conveyor 602 in the conveying pipe 3 to form a gas-solid two-phase flow. By adjusting the opening and closing degree of the baffle 804, the flow cross-sectional area in the conveying pipe 3 can be changed, thereby controlling the amount of air entering. This keeps the mixing ratio of biomass raw materials and air in the optimal combustion range, reduces incomplete combustion caused by insufficient air or heat loss caused by excessive air, improves the utilization efficiency of biomass energy, and reduces the emission of harmful gases such as carbon monoxide.
