Description

Technical Field

[0001] This utility model relates to the field of dust removal and purification technology, specifically a biomass boiler fly ash treatment device. Background Technology

[0002] Biomass boilers are a type of boiler that uses biomass energy as fuel. They are classified into biomass steam boilers, biomass hot water boilers, biomass hot air furnaces, biomass thermal oil furnaces, vertical biomass boilers, and horizontal biomass boilers.

[0003] However, in most existing biomass boilers, fly ash falls naturally to the bottom by weight during fly ash treatment, is then conveyed by an induced draft fan, and finally filtered by a bag filter. This process can easily lead to some of the combusted fly ash accumulating on the surface of the ash hopper and not being conveyed. Over time, this can clog the ash discharge port, resulting in poor ash discharge and reduced fly ash treatment efficiency. To address these issues, the inventors propose a biomass boiler fly ash treatment device to solve the problems mentioned above. Utility Model Content

[0004] In order to solve the problem that some of the fly ash from biomass boilers tends to accumulate on the surface of the ash hopper and easily clog the ash discharge port during fly ash treatment, the purpose of this utility model is to provide a fly ash treatment device for biomass boilers.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: a biomass boiler fly ash treatment device, comprising a biomass boiler body, a fixing ring fixedly provided on the outer surface of the biomass boiler body, a supporting leg fixedly provided on the bottom surface of the fixing ring, an ash hopper fixedly provided on the bottom surface of the biomass boiler body, a fixing plate fixedly provided on the bottom surface of the fixing ring, an L-shaped plate slidably provided inside the fixing plate, a spring fixedly connected between the inner wall of the fixing plate and the L-shaped plate, a connecting plate fixedly provided on the bottom surface of the L-shaped plate, a circular ring fixedly provided between the connecting plates, a rubber rod fixedly provided on the top surface of the circular ring, the rubber rod being able to fit against the top surface of the ash hopper, a limiting groove opened in the fixing plate, the L-shaped plate slidably provided in the limiting groove, a sliding rod fixedly provided in the limiting groove, and the L-shaped plate slidably sleeved on the outer surface of the sliding rod;

[0006] A motor is located below the fixed ring, and a rotating shaft is fixedly mounted on the output end of the motor. A cam is fixedly fitted on the outer surface of the rotating shaft, and a contact plate is fixedly mounted on the outer surface of the ring. The cam can contact the top surface of the contact plate. An ear plate is fixedly mounted on the bottom surface of the fixed ring, and the motor is installed on one side of the ear plate. The rotating shaft rotates through the ear plate. First, when fly ash needs to be treated, the fly ash falls naturally to the bottom by its weight. The fly ash is then sucked out of the biomass boiler body by turning on the induced draft fan. Then, the motor is turned on, causing the rotating shaft to drive the cam to rotate. When the cam contacts the contact plate, it causes the contact plate to drive the ring to descend, and the connecting plate to drive the L-shaped plate to descend and slide on the outer surface of the slide rod. At the same time, the spring is compressed and deformed. Then, when the cam disengages from the contact plate, it causes the spring to return to its original position, which causes the L-shaped plate to drive the connecting plate to rise, causing the ring to rise and the rubber rod to strike the ash hopper, thus preventing fly ash from adhering to the ash hopper after long-term use.

[0007] Next, the air cannon is turned on, so that the nozzle sprays high-pressure airflow to instantly impact the fly ash accumulation, keeping the fly ash in a loose state and preventing the fly ash from depositing and clumping at the bend of the ash discharge pipe. Then, a bag filter is used for filtration, and the filtered gas is discharged from the air outlet.

[0008] Preferably, the bottom end of the ash hopper is fixedly provided with an ash discharge pipe, and the ash hopper and the ash discharge pipe are interconnected. An installation plate is fixedly provided on the outer surface of the ash discharge pipe, and a positioning plate is fixedly provided on the bottom surface of the installation plate. An air cannon body is installed inside the positioning plate. A nozzle is fixedly provided on the outer surface of the air cannon body. The nozzle is fixedly inserted into the ash discharge pipe. A through groove is opened in the ash discharge pipe, and the nozzle is fixedly inserted into the through groove.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. The circular ring moves up and down repeatedly, causing the rubber rod to strike the ash hopper, thus preventing fly ash from adhering to the ash hopper after prolonged use, ensuring smooth ash conveying and improving fly ash treatment efficiency.

[0011] 2. By activating the air cannon, the nozzle sprays a high-pressure airflow that instantly impacts the fly ash accumulation, keeping the fly ash loose and preventing it from accumulating and agglomerating at the bend of the ash discharge pipe, thus avoiding a decrease in dust removal efficiency due to ash accumulation in the ash discharge pipe.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Figure 1-7As shown, this utility model provides a biomass boiler fly ash treatment device, including a biomass boiler body 1, a fixing ring 11 fixedly provided on the outer surface of the biomass boiler body 1, a support leg 12 fixedly provided on the bottom surface of the fixing ring 11, an ash hopper 13 fixedly provided on the bottom surface of the biomass boiler body 1, a fixing plate 3 fixedly provided on the bottom surface of the fixing ring 11, an L-shaped plate 33 slidably provided in the fixing plate 3, a spring 32 fixedly connected between the inner wall of the fixing plate 3 and the L-shaped plate 33, a connecting plate 34 fixedly provided on the bottom surface of the L-shaped plate 33, a ring 35 fixedly provided between the connecting plates 34, a rubber rod 36 fixedly provided on the top surface of the ring 35, the rubber rod 36 can fit against the top surface of the ash hopper 13, a limiting groove 301 is opened in the fixing plate 3, the L-shaped plate 33 is slidably provided in the limiting groove 301, a sliding rod 31 is fixedly provided in the limiting groove 301, and the L-shaped plate 33 is slidably sleeved on the outer surface of the sliding rod 31;

[0023] A motor 21 is located below the fixed ring 11. A rotating shaft 22 is fixedly mounted on the output end of the motor 21. A cam 23 is fixedly fitted on the outer surface of the rotating shaft 22. A contact plate 37 is fixedly mounted on the outer surface of the ring 35. The cam 23 can contact the top surface of the contact plate 37. An ear plate 2 is fixedly mounted on the bottom surface of the fixed ring 11. The motor 21 is mounted on one side of the ear plate 2. The rotating shaft 22 rotates through the ear plate 2. Two sets of motors 21 are provided, and the parameters of the two sets of motors 21 are exactly the same and they run synchronously. By turning on the motor 21, the rotating shaft 22 is driven. When the cam 23 rotates and contacts the contact plate 37, it causes the contact plate 37 to drive the ring 35 to descend, and the connecting plate 34 to drive the L-shaped plate 33 to descend and slide on the outer surface of the slide rod 31. At the same time, the spring 32 is compressed and deformed. Then, when the cam 23 disengages from the contact plate 37, it causes the spring 32 to return to its original position, which in turn causes the L-shaped plate 33 to drive the connecting plate 34 to rise, causing the ring 35 to rise, and causing the rubber rod 36 to strike the ash hopper 13. This prevents fly ash from adhering to the ash hopper 13 after long-term use, ensuring smooth ash conveying and improving fly ash treatment efficiency.

[0024] A ash discharge pipe 14 is fixedly provided at the bottom end of the ash hopper 13, and the ash hopper 13 and the ash discharge pipe 14 are interconnected. An installation plate 4 is fixedly provided on the outer surface of the ash discharge pipe 14, and a positioning plate 41 is fixedly provided on the bottom surface of the installation plate 4. An air cannon body 42 is installed in the positioning plate 41. A nozzle 43 is fixedly provided on the outer surface of the air cannon body 42. The nozzle 43 is fixedly inserted into the ash discharge pipe 14. A through groove 15 is opened in the ash discharge pipe 14, and the nozzle 43 is fixedly inserted into the through groove 15.

[0025] By adopting the above technical solution, the air cannon body 42 includes an air storage tank for storing compressed gas, an air inlet pipe for connecting to the compressed air pipeline to replenish the air pressure in the compressed pipe, and a solenoid valve on the surface of the nozzle 43 to control the instantaneous release of compressed air. By opening the air cannon body 42, the nozzle 43 sprays out a high-pressure airflow to instantly impact the fly ash accumulation, keeping the fly ash in a loose state, preventing fly ash from depositing and agglomerating at the bend of the ash discharge pipe 14, and avoiding the accumulation of ash in the ash discharge pipe 14, which would lead to a decrease in dust removal efficiency.

[0026] Working principle: First, when fly ash needs to be treated, the fly ash falls naturally to the bottom by its weight. The induced draft fan is turned on to suck the fly ash out of the biomass boiler body 1. Then, the motor 21 is turned on, which causes the rotating shaft 22 to drive the cam 23 to rotate. When the cam 23 contacts the contact plate 37, it causes the contact plate 37 to drive the ring 35 to descend, and the connecting plate 34 to drive the L-shaped plate 33 to descend and slide on the outer surface of the slide rod 31. At the same time, the spring 32 is compressed and deformed. Then, when the cam 23 disengages from the contact plate 37, it causes the spring 32 to return to its original position, which causes the L-shaped plate 33 to drive the connecting plate 34 to rise, causing the ring 35 to rise, and the rubber rod 36 to strike the ash hopper 13, thereby preventing fly ash from adhering to the ash hopper 13 after long-term use.

[0027] Next, the air cannon body 42 is turned on, so that the nozzle 43 sprays out a high-pressure airflow to instantly impact the fly ash accumulation, keeping the fly ash in a loose state and preventing the fly ash from depositing and clumping at the bend of the ash discharge pipe 14. Then, a bag filter is used for filtration, and the filtered gas is discharged from the air outlet.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
