Description

Technical Field

[0001] This utility model relates to the field of boiler technology, and more specifically to a boiler equipped with a boiler cleaning structure. Background Technology

[0002] Boilers, as core thermal energy equipment in the industrial and energy sectors, are widely used in power, chemical, and manufacturing industries. During long-term operation, scale, soot, and oxide layers inevitably accumulate on the inner walls and heating surfaces of boilers, leading to decreased thermal efficiency, increased energy consumption, and even safety hazards such as localized overheating, corrosion, or tube rupture. Therefore, regular and effective cleaning of boilers is a crucial measure to ensure safe operation, extend service life, and maintain high energy efficiency.

[0003] As shown in the prior art published in CN211650193U, although this prior art can move the scale removal plate along the lower inner wall of the boiler body under the push of a hydraulic pusher, and break up the soaked scale through the serrations on the scale removal plate, and then discharge the scale through the scale outlet pipe, thus improving the scale cleaning efficiency, the cleaning plate in this prior art can only remove scale from the inner wall at the bottom of the boiler, while the inner wall at the top of the boiler cannot be cleaned. This results in the boiler not being fully cleaned and maintained, which in turn affects the practicality of the technical solution. Utility Model Content

[0004] To overcome the aforementioned deficiencies of the prior art, this utility model provides a boiler equipped with a boiler cleaning structure. A servo motor drives the main gear, which in turn drives the column to rotate via a driven gear. The column rotates the card plate and the moving column via a slot. Because the moving column is threadedly connected to the screw ring, the moving column can rotate and move into the furnace body. This rotation drives the scraper ring to reciprocate within the furnace body, achieving a comprehensive cleaning effect on the inner wall of the furnace body and ensuring the cleaning effect on scale inside the furnace body, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a boiler with a boiler cleaning structure, comprising a boiler body, wherein a maintenance component for cleaning scale is provided inside the boiler body, and the maintenance component is driven to operate outside the boiler body by a power component;

[0006] The power component includes a column, which is movably connected to one side of the furnace body via a bearing. A slot is provided on the side of the main body near the furnace body. A card plate and a movable column are provided inside the slot. The movable column is installed on the side of the card plate near the furnace body, and the end of the movable column away from the card plate passes through the furnace body and extends into the furnace body. A threaded ring is installed on the side of the furnace body corresponding to the column. The threaded ring is located inside the slot and is sleeved on the outside of the movable column. The movable column and the threaded ring are threadedly connected.

[0007] The column is fitted with a driven gear on the outside of one end near the furnace body, and the driven gear is engaged with the main gear at the top of the driven gear.

[0008] In a preferred embodiment, both the cross-section of the card plate and the cross-section of the card slot are rectangular, and the outer side of the card plate is in contact with the inner wall of the card slot.

[0009] In a preferred embodiment, the maintenance component includes a sealing plate disposed inside the furnace body. The sealing plate is located inside the furnace body at one end near the column, and the end of the movable column near the furnace body is fixed together with the sealing plate. A scraper ring for cleaning the furnace body is sleeved on the outside of the sealing plate, and a plurality of connecting columns for connecting the sealing plate are installed inside the scraper ring.

[0010] In a preferred embodiment, a servo motor is installed on the side of the furnace body near the column, and the output shaft of the servo motor is fixed together with the main gear.

[0011] In a preferred embodiment, a feed pipe is fixedly connected to the top of one end of the furnace body near the column, and a discharge pipe is fixedly connected to the bottom of the furnace body on the side away from the column. A drain pipe is provided at the bottom of the discharge pipe, and the drain pipe is fixedly connected to the bottom of the furnace body on the side away from the column.

[0012] In a preferred embodiment, a sealing shell is installed on the side of the furnace body near the column. The sealing shell is sleeved on the outside of the column, the main gear, the driven gear and the servo motor, and dustproof nets are embedded on both the front and rear sides of the sealing shell.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] The column is driven to rotate by a power component. The column drives the card plate and the moving column to rotate through the slot. Because the moving column is threadedly connected to the screw ring, the moving column can rotate and move into the furnace body. This rotation drives the scraper ring to move back and forth inside the furnace body, achieving a comprehensive cleaning effect on the inner wall of the furnace body and ensuring the cleaning effect on the scale inside the furnace body.

[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] Refer to the instruction manual appendix Figure 1-5 This utility model provides a boiler with a boiler cleaning structure, including a boiler body 1. The boiler body 1 has a maintenance component for cleaning scale inside, and the maintenance component is driven by a power component outside the boiler body 1. The power component includes a column 2, which is movably connected to one side of the boiler body 1 by a bearing. A slot 3 is opened on the side of the main body near the boiler body 1. A card plate 4 and a moving column 5 are provided inside the slot 3. The moving column 5 is installed on the side of the card plate 4 near the boiler body 1, and the end of the moving column 5 away from the card plate 4 passes through the boiler body 1 and extends into the interior of the boiler body 1. A threaded ring 6 is installed on the side of the boiler body 1 corresponding to the column 2. The threaded ring 6 is located inside the slot 3 and is sleeved on the outside of the moving column 5. The moving column 5 and the threaded ring 6 are threadedly connected. A driven gear 7 is sleeved on the outside of the end of the column 2 near the boiler body 1, and a main gear 8 meshes with the top of the driven gear 7.

[0023] When using the aforementioned maintenance components to clean the scale inside the furnace body 1, the operator needs to deliver the scale cleaner into the furnace body 1. A feed pipe 13 is fixedly connected to the top of the furnace body 1 near the column 2, and a discharge pipe 14 is fixedly connected to the bottom of the furnace body 1 away from the column 2. A drain pipe 15 is located at the bottom of the discharge pipe 14, and is fixedly connected to the bottom of the furnace body 1 away from the column 2. This allows the operator to deliver the scale cleaner into the furnace body 1 via the feed pipe 13, facilitating the maintenance components to agitate the scale cleaner and clean the scale inside the furnace body 1.

[0024] The maintenance component includes a sealing plate 9 located inside the furnace body 1. The sealing plate 9 is situated inside the furnace body 1 at the end near the column 2, and the end of the movable column 5 near the furnace body 1 is fixed to the sealing plate 9. A scraper ring 10 for cleaning the furnace body 1 is fitted over the sealing plate 9, and multiple connecting columns 11 for connecting the sealing plate 9 are installed inside the scraper ring 10. To improve the convenience of the power component driving the maintenance component, a servo motor 12 is installed on the side of the furnace body 1 near the column 2, and the output shaft of the servo motor 12 is fixed to the main gear 8.

[0025] In this way, the main gear 8 can be driven by the servo motor 12, and the main gear 8 drives the column 2 to rotate through the driven gear 7. Since the cross-section of the card plate 4 and the cross-section of the card slot 3 are both rectangular, and the outside of the card plate 4 is in contact with the inner wall of the card slot 3, the column 2 can drive the card plate 4 and the moving column 5 to rotate through the card slot 3. Since the moving column 5 is threadedly connected to the screw ring 6, the moving column 5 moves along the screw ring 6 into the furnace body 1 while rotating, and thus rotates and drives the sealing plate 9 and the scraper ring 10 to move inside the furnace body 1. Furthermore, by the forward and reverse rotation of the servo motor 12, the moving column 5 can drive the scraper ring 10 to reciprocate inside the furnace body 1, thereby achieving the effect of cleaning the inner wall of the furnace body 1 in all directions.

[0026] To ensure the meshing stability of the main gear 8 and the driven gear 7, it is necessary to prevent external dust and other impurities from entering. Therefore, a sealing shell 16 is installed on the side of the furnace body 1 near the column 2. The sealing shell 16 is fitted over the column 2, the main gear 8, the driven gear 7, and the servo motor 12. Dustproof nets 17 are embedded on both the front and rear sides of the sealing shell 16. The sealing shell 16 encapsulates and protects the main gear 8, the driven gear 7, and the servo motor 12, preventing external dust and other impurities from adhering to the outside of the main gear 8 and the driven gear 7, thus ensuring the transmission stability of the main gear 8 and the driven gear 7. Simultaneously, the dustproof nets 17 ensure air circulation inside the sealing shell 16, thereby preventing heat accumulation that could affect the performance of the servo motor 12.

[0027] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
