Description

Technical Field

[0001] This invention relates to the field of boiler feeding technology, and in particular to a structure for preventing coal burning in a biomass boiler and its method of use. Background Technology

[0002] A biomass boiler is a boiler that uses biomass energy as fuel. During the operation of a biomass boiler, biomass fuel needs to be continuously supplied into the boiler. The high-temperature gas generated by combustion in the boiler will scorch the material on the feed hopper through the feed hopper, which will cause the material on the feed hopper to burn. In order to avoid this phenomenon, a biomass boiler anti-burning hopper structure is needed.

[0003] In the existing technology, water spraying or inert gas is generally used to prevent the material in the coal hopper from burning in order to achieve the anti-burn treatment of the coal hopper. However, water spraying will cause the material to consume more heat when burning, while inert gas will cause incomplete combustion inside the furnace, which will also lead to heat loss. Summary of the Invention

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A structure for preventing coal burning in a biomass boiler includes: The feed pipe includes a vertical section, a horizontal section and an inclined section connected in sequence. The inclined section of the feed pipe has two first baffles on the top inner wall and two second baffles on the bottom inner wall, and the first baffles and second baffles are staggered. Two feeding components are provided, both of which are disposed through the inner wall of the bottom of the inclined section of the feed pipe, and the two feeding components are respectively close to the two second baffles; Two feeding assemblies are slidably disposed on the outer wall of the vertical section of the feeding pipe, and the two feeding assemblies are used to control the material supply; The output component is disposed through the inclined section sidewall of the feed pipe, and the output component abuts against the bottom inner wall of the horizontal section of the feed pipe; A guide plate is provided at the end of the horizontal section of the feed pipe.

Two supports, both of which are mounted on the outer wall of the feed pipe; A power assembly is disposed on the outer side wall of the two supports, and the power assembly is used to drive the partition to move.

[0007] A further improvement of the present invention is that the power assembly includes: A lead screw, which is rotatably mounted on the side walls of two supports; The motor is mounted on one of the side walls of the bracket, and the output shaft and lead screw of the motor are fixed. Guide rods are mounted on the side walls of the two supports; A transmission block is slidably connected to a guide rod. The side wall of the transmission block has a threaded hole that is compatible with the lead screw.

[0008] A further improvement of the present invention is that it further includes: A connecting rod, wherein both ends of the connecting rod are provided with ball heads; Two connecting seats, one of which is disposed on the side wall of the partition plate and the other of which is disposed on the side wall of the transmission block, and two ball heads are rotatably connected to the two connecting seats respectively.

[0009] A further improvement of the present invention is that the pneumatic assembly includes: L-shaped plate, the L-shaped plate being disposed on the outer wall of the feed pipe; A sleeve is provided on the side wall of an L-shaped plate. A piston is slidably disposed inside the sleeve. A sleeve rod is provided at the end of the piston, and the sleeve rod and the partition are fixed together. A first one-way valve is disposed through the end of the sleeve; The second check valve is disposed through the outer wall of the sleeve.

[0010] A further improvement of the present invention is that the feeding assembly includes: A first connecting seat is disposed on the outer wall of the feed pipe. A plurality of first air supply pipes are provided through the outer wall of the first connecting seat, and each first air supply pipe passes through the inner wall of the feed pipe. The first pipe body has one end connected to the first one-way valve.

[0011] A further improvement of the present invention is that a self-regulating pressure regulating valve is provided at the end of the first connecting seat, and the other end of the first pipe body is connected to the self-regulating pressure regulating valve.

[0012] A further improvement of the present invention is that the output component includes: A gas storage tank is disposed on the outer wall of the feed pipe; The second connecting seat is disposed on the outer wall of the feed pipe. Multiple second air supply pipes are provided through the outer wall of the second connecting seat, and each second air supply pipe passes through the inner wall of the feed pipe. Each second air supply pipe abuts against the inner wall at the bottom of the feed pipe. Two second pipes, both of which are connected to the gas storage tank, and each of the two second pipes is connected to one of the two first pipes respectively; A solenoid valve, wherein the solenoid valve is installed through the outer wall of the gas storage tank; The gas supply pipe has one end connected to a solenoid valve and the other end connected to a second connector.

[0013] A further improvement of the present invention is that a feed hopper is provided at the top of the feed pipe.

[0014] A method for using an anti-coal-burning hopper structure in a biomass boiler includes: Turn on the power component switch to move the partition 4 through the power component, so that the partition 4 is pulled out of the feed pipe and the material passes through the feed component feed pipe to avoid backfire in the feed pipe. During the movement of the feeding component, gas is forced into the feeding component through the pneumatic component. During the reset process of the feeding component, external gas enters the pneumatic component. This cycle continues, enabling the pneumatic component to periodically output gas. Part of the gas enters the output component for storage, while another part of the gas enters the feeding component. The gas output by the feeding component can blow the material, causing it to move along the surface of the second baffle. Under the action of the first baffle, a large amount of material is prevented from moving to the feed pipe with the airflow, further preventing fuel combustion in the feed pipe. During the feeding process, the output component is switched on and off periodically. When the output component is switched on, the gas in the gas storage tank enters the feeding component. The gas output by the feeding component blows the material at the bottom of the feed pipe to the guide plate, where it is guided by the guide plate to enter the furnace in a parabolic trajectory, thus preventing the high temperature inside the furnace from entering the feed pipe.

[0015] Compared with the prior art, the present invention has at least the following beneficial technical effects: This invention controls the movement of the feeding assembly via a power component, allowing the feeding assembly to withdraw the feed pipe and allow material to enter below, while simultaneously sealing the feed pipe. This design effectively blocks the continuous flow of material within the feed pipe, creating an interval during material supply. This significantly reduces the possibility of backfire caused by continuous material accumulation and temperature rise within the feed pipe, structurally ensuring the safety of the feeding process and preventing equipment damage or even more serious accidents due to backfire. A first baffle on the top inner wall and a second baffle on the bottom inner wall of the inclined section of the feed pipe are staggered. When the gas output from the feeding assembly blows the material, the first baffle prevents a large amount of material from moving directly to the bottom of the feed hopper with the airflow, preventing the fuel in the feed hopper from burning due to a large influx of material and the airflow, further enhancing the anti-combustion effect and ensuring the stable operation of the biomass boiler feeding system.

[0016] The pneumatic and feeding components work in close coordination. When the feeding component moves, it forces gas into the feeding component; when it resets, external gas enters the pneumatic component, achieving periodic gas output. The gas output from the feeding component blows the material, causing it to move along the surface of the second baffle. This feeding method utilizes the power of the gas and the guiding effect of the baffle to precisely control the direction and speed of the material's movement, ensuring that the material enters the guide plate along a predetermined path and then into the furnace. This improves the accuracy and efficiency of feeding and avoids blockage or disorderly accumulation of material in the feed pipe. Two feeding components are slidably mounted on the outer wall of the vertical section of the feed pipe to control the material supply. This design allows operators to flexibly adjust the material supply according to actual needs, changing the size of the channel through which the material enters the feed pipe by sliding the feeding components, achieving precise control of the material supply and meeting the operational requirements of biomass boilers under different working conditions.

[0017] Furthermore, the present invention enables the movement of the partition plate through the connecting seat, ball head and connecting rod during the movement of the transmission block, so that the partition plate is pulled out of the feed pipe, and the material in the feed hopper enters the area below the partition plate through the partition plate. At the same time, another partition plate seals the feed pipe, thereby preventing backfire in the feed pipe and preventing the material in the feed hopper from burning. Attached Figure Description

[0033] Furthermore, it also includes: Connecting rod 11, with ball heads 10 at both ends; Two connecting seats 9, one of which is located on the side wall of the partition 4 and the other is located on the side wall of the transmission block 8, and two ball heads 10 are rotatably connected to the two connecting seats 9 respectively.

[0034] Furthermore, the pneumatic components include: L-shaped plate 12, L-shaped plate 12 is disposed on the outer wall of feed pipe 1; Sleeve 23 is mounted on the side wall of L-shaped plate 12. Piston 27 is slidably mounted inside sleeve 23. Sleeve rod 24 is mounted at the end of piston 27 and sleeve rod 24 is fixed to partition plate 4. The second one-way valve 26 is disposed through the outer wall of the sleeve 23; The first one-way valve 25 is disposed through the end of the sleeve 23.

[0035] Furthermore, the feeding assembly includes: A first connecting seat 19 is disposed on the outer wall of the feed pipe 1. Multiple first air supply pipes 21 are provided through the outer wall of the first connecting seat 19. Each first air supply pipe 21 passes through the inner wall of the feed pipe 1. A self-operated pressure regulating valve 30 is provided at the end of the first connecting seat 19. The first pipe body 14 has one end connected to the first one-way valve 25 and the other end connected to the self-regulating pressure regulating valve 30.

[0036] Furthermore, the output components include: Gas storage tank 16 is installed on the outer wall of feed pipe 1; The second connecting seat 20 is disposed on the outer wall of the feed pipe 1. A plurality of second air supply pipes 22 are provided through the outer wall of the second connecting seat 20, and each second air supply pipe 22 penetrates the inner wall of the feed pipe 1.

[0037] Furthermore, a feed hopper 3 is provided at the top of the feed pipe 1.

[0038] Example 2 like Figures 1 to 5 As shown, this embodiment of the invention provides a method for using an anti-coal-burning hopper structure in a biomass boiler, including: When the power unit is switched on, the partition 4 is moved by the power unit, so that the partition 4 is pulled out of the feed pipe 1, and the material enters the area below the partition 4 through the partition 4. At the same time, another partition 4 seals the feed pipe 1 to prevent backfire from occurring in the feed pipe 1. During the movement of the partition 4, the gas in the pneumatic component is forced into the feeding component. During the reset process of the partition 4, the external gas enters the pneumatic component. This cycle continues, enabling the pneumatic component to periodically output gas. Part of the gas enters the output component for storage, while another part of the gas enters the feeding component. The gas output by the feeding component can blow the material, causing the material to move along the surface of the second baffle 29. Under the action of the first baffle 28, a large amount of material is prevented from moving with the airflow to the bottom of the feed hopper 3, further preventing the fuel in the feed hopper 3 from burning. During the feeding process, the output component is switched on and off periodically. When the output component is switched on, the gas in the gas storage tank enters the feeding component. The gas output by the feeding component blows the material at the bottom of the feed pipe 1 to the guide plate 2. The material is guided by the guide plate 2 and enters the furnace in a parabolic trajectory, thus preventing the high temperature in the furnace from entering the feed pipe 1.

[0039] More specifically: When in use, biomass fuel is placed into the feed hopper 3, and the switch of motor 13 is turned on. When motor 13 is working, it drives the lead screw 6 to rotate, which in turn drives the two transmission blocks 8 to move. During the movement of transmission blocks 8, the partition 4 can be moved through the connecting seat 9, ball head 10 and connecting rod 11, so that the partition 4 is pulled out of the feed pipe 1. The material in the feed hopper 3 enters the area below the partition 4 through the partition 4. At the same time, the other partition 4 seals the feed pipe 1, thereby preventing backfire in the feed pipe 1 and preventing the material in the feed hopper 3 from burning. During the movement of the partition 4, the gas in the sleeve 23 is forced into the first tube 14 through the first one-way valve 25 by the sleeve rod 24 and the piston 27. During the reset of the partition 4, the outside gas enters the sleeve 23 through the second one-way valve 26. This cycle is repeated so that the first one-way valve 25 can periodically output gas. Under the action of the self-regulating pressure regulating valve 30, part of the gas enters the gas storage tank 16 for storage, and another part of the gas enters the first connecting seat 19 through the self-regulating pressure regulating valve 30. The gas in the first connecting seat 19 is then output through the first gas delivery pipe 21. The gas output from the first gas delivery pipe 21 can blow the material, causing the material to move along the surface of the second baffle 29. Under the action of the first baffle 28, a large amount of material is prevented from moving with the airflow to the bottom of the feed hopper 3, further preventing fuel combustion in the feed hopper 3. During the feeding process, the solenoid valve 17 is periodically switched on and off. When the solenoid valve 17 is switched on, the gas in the gas storage tank 16 enters the gas delivery pipe 18 through the solenoid valve 17, then enters the second connecting seat 20, and is output through the second gas delivery pipe 22. The gas output through the second gas delivery pipe 22 blows the material at the bottom of the feed pipe 1 to the guide plate 2, where it is guided by the guide plate 2 and enters the furnace in a parabolic trajectory, thus again preventing the high temperature in the furnace from entering the feed pipe 1.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
