Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of energy-saving combustion machines, and specifically relates to an energy-saving biomass gas combustion machine. BACKGROUND

[0002] As a carbon-neutral renewable energy, biomass energy has a wide source and low pollution emission, and its combustion utilization technology has been widely concerned in the fields of industrial heat supply and civil heating. As a core equipment for efficient conversion of biomass energy, the performance optimization of the biomass gas combustion machine is of key significance to promote the development of the biomass energy industry. The existing combustion machine has a simple ash removal structure, and the accumulated ash and unburned materials cannot be recycled. In addition, the connection part of the fan and the spiral feeding port lacks an effective anti-backflow structure, and the high-temperature gas flow and materials are easy to reverse into the pipeline, causing waste of raw materials, pipeline blockage and safety hazards, thereby restricting the energy utilization efficiency and operation stability.

[0003] Publication No. CN118499766A discloses a biomass boiler energy-saving combustion machine, which comprises a base, a box body 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 an ash removal mechanism arranged in the collection shell. The power mechanism drives the straight groove plate to rotate, the arc-shaped tooth block is engaged with the rack to drive the racks on both sides to relatively move away, and the movable rod is moved through the connecting plate to stretch the spring I, so that the two crushing blocks move away from each other. When the arc-shaped tooth block is not engaged with the rack, the two crushing blocks are relatively close to each other under the action of the spring I to reset. Therefore, in the process of the two crushing blocks reciprocating and moving away from each other, the larger particles remaining on the screen can be crushed by extrusion, thereby effectively improving the sufficiency and stability of the combustion machine combustion.

[0004] The device can realize the effect of crushing and extruding the larger particles remaining on the screen in the process of the two crushing blocks reciprocating and moving away from each other, but when the device is used, backflow of the fan and the spiral feeding port cannot be prevented, and the ash and unburned materials cannot be effectively recycled. Therefore, an energy-saving biomass gas combustion machine is proposed, which can accurately feed, efficiently remove ash, prevent air flow backflow, thereby improving the utilization efficiency of biomass energy, reducing operation cost, and ensuring safe and stable operation of the equipment.

[0034] Adopt the above scheme: by starting the second servo motor 802 drive second connecting rod 803 and baffle 804 rotation, and then through the rotation of baffle 804 to the inside passage of the conveying pipe 3 opening and closing, and through the buffer spring 807 extrusion rack plate 806 can be on the transmission gear 805 buffer, and then on the baffle 804 buffer, when the ignition is not and the fan 4 is closed, through the baffle 804 inside the conveying pipe 3 is closed, can prevent the biomass raw materials in the initial stage of transportation due to airflow turbulence and into the pipeline of the fan 4, reduce the waste of raw materials and pipeline accumulation.

[0035] The working principle and use process of the present application: first, by pouring the material into the inside of the feeding cylinder 5, starting the first servo motor 601 drive screw conveyor rod 602 rotation, and then through the screw conveyor rod 602 to the material conveying, make it through the conveying pipe 3 into the inside of the combustion cylinder 2 after starting the ignition rod 9 combustion, screw conveyor rod 602 rotation synchronous drive first bevel gear 603 rotation, and through the rotation of the first bevel gear 603 drive the second bevel gear 605, first connecting rod 604 and eccentric wheel 606 rotation, so that the eccentric wheel 606 rotation constantly extrusion and separation of the ash filter disc 607, and then make the ash filter disc 607 shaking, so that the burning dust through the filter hole 608 fall into the inside of the recycling box 7, and then the dust recycling, and can drive the unburnt material vibration, make it close to the source, improve the combustion efficiency, and vibration with feeding opening and closing, vibration is in the combustion cylinder 2 inside the material is about to burn out state.

[0036] Secondly, by starting the second servo motor 802 drive second connecting rod 803 and baffle 804 rotation, and then through the rotation of baffle 804 to the inside passage of the conveying pipe 3 opening and closing, and through the buffer spring 807 extrusion rack plate 806 can be on the transmission gear 805 buffer, and then on the baffle 804 buffer, when the ignition is not and the fan 4 is closed, through the baffle 804 inside the conveying pipe 3 is closed, can prevent the biomass raw materials in the initial stage of transportation due to airflow turbulence and into the pipeline of the fan 4, reduce the waste of raw materials and pipeline accumulation, the device starts, through the second servo motor 802 control the opening and closing degree of baffle 804, and then adjust the elastic pretightening force of two sets of buffer spring 807, can control the gas flow into the conveying pipe 3 accurately, let the biomass raw materials and airflow form more reasonable gas solid mixing state and enter the inside of the combustion cylinder 2.

[0037] When the baffle 804 is closed, the material pushed by the first servo motor 601 driving the screw conveying rod 602 will form a stable pre-storage area in the conveying pipe 3 section between the baffle 804 and the screw conveying rod 602, which can avoid the dispersion and accumulation of the material due to the lack of blocking. 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, which can make the material in the pre-storage area enter the combustion cylinder 2 in a uniform and continuous state, ensuring the stability of the subsequent combustion process and avoiding the flame fluctuation caused by intermittent feeding.

[0038] When not ignited, the inside of the combustion cylinder 2 is at room temperature and needs to be pre-processed by the fan 4 pipeline. After the baffle 804 is closed, a physical isolation barrier can be formed to prevent dust, moisture and other impurities in the external environment from entering the conveying pipe 3 and the feeding cylinder 5 through the fan 4 pipeline in the reverse direction, which can prevent the biomass raw material from being damp and clumping, prevent impurities from mixing into the raw material to affect the combustion efficiency, ensure the dryness and cleanliness of the raw material, and ensure the stability of the calorific value of the raw material during combustion.

[0039] When the material in the combustion cylinder 2 is burning, the vibration action of the ash filter disc 607 and the feeding action of the screw conveying rod 602 are linked. When the screw conveying rod 602 stops feeding, the first bevel gear 603 stops rotating with the screw conveying rod 602, the second bevel gear 605, the first connecting rod 604 and the eccentric wheel 606 stop moving synchronously, and the ash filter disc 607 stops vibrating. When the screw conveying rod 602 starts feeding again, the ash filter disc 607 starts vibrating again. This linkage design can ensure that the ash filter disc 607 only vibrates to clean ash when the material in the combustion cylinder 2 is burning, avoid unnecessary vibration in the absence of ash, reduce equipment energy consumption, reduce the friction loss between the ash filter disc 607 and the inner wall of the combustion cylinder 2, and prolong the service life of the parts.

[0040] The arc surface structure at the top end of the ash filter disc 607 can guide the unburned material to gather in the center area of the combustion cylinder 2 when vibrating, making it easier to approach the source of the ignition rod 9, improving the secondary combustion efficiency of the unburned material. The filter holes 608 arranged in a ring array can ensure that the ash falls uniformly and avoid the problem of incomplete ash cleaning caused by the blockage of a single filter hole. The recycling box 7 is slidingly connected to the base 1. When the ash collected in the recycling box 7 reaches the preset amount, the recycling box 7 can be directly pulled out for ash cleaning or recycling, which is convenient to operate and does not need to disassemble the equipment, reducing maintenance time.

[0041] During the process of adjusting the opening degree of the baffle 804, the buffer spring 807 continuously exerts a pressing force on the rack plate 806 through its elastic deformation, and the pressing force is transmitted to the second connecting rod 803 through the meshing transmission between the rack plate 806 and the transmission gear 805, thereby buffering the rotating action of the baffle 804. When the baffle 804 reaches the target opening angle, the elastic pre-tightening force of the buffer spring 807 can fix the relative position of the rack plate 806 and the transmission gear 805, so as to avoid the angle deviation of the baffle 804 caused by the airflow impact generated by the fan 4, and ensure the air flow control accuracy. At the same time, the annular array distribution design of the buffer spring 807 can balance the stress of the rack plate 806, avoid the jamming or deformation of the rack plate 806 caused by unilateral stress, and ensure the smoothness of the adjusting action of the baffle 804.

[0042] After the fan 4 is started, the external air is pressurized by the fan 4 and enters the conveying pipe 3, and is mixed with the biomass raw materials conveyed by the spiral conveying rod 602 to form a gas-solid two-phase flow in the conveying pipe 3. By adjusting the opening degree of the baffle 804, the flow area in the conveying pipe 3 can be changed, and then the air intake amount can be controlled, so that the mixing ratio of the biomass raw materials and the air is maintained in the optimal combustion interval, the incomplete combustion caused by insufficient air or the heat loss caused by excessive air is reduced, the utilization efficiency of the biomass energy is improved, and the emission of harmful gases such as carbon monoxide is reduced.
