A soot cleaning device for a steam boiler

Abstract

This utility model provides a stain cleaning device for a steam boiler, relating to the field of steam boiler technology. A motor drives an output shaft to rotate, which in turn drives a rotating shaft, causing a lifting plate to move vertically. Because a telescopic rod and spring are installed below the lifting plate, it continuously performs repeated lifting and lowering movements. A rotating shaft is movably connected to the middle of the lifting plate, causing it to rotate while also performing repeated vertical movements. This allows the scraper with brushes to move both horizontally and vertically, effectively cleaning the dirt on the inner wall of the boiler and achieving a thorough cleaning effect. The device is fixed to the side of the boiler body with multiple screws, and a sealing ring is tightly fitted between the water outlet pipe and the boiler body to prevent liquid leakage. After prolonged use, when dirt accumulates in the water outlet pipe, it can be disassembled for cleaning to prevent blockage.

Description

Technical Field

[0001] This utility model relates to the field of steam boiler technology, and in particular to a stain cleaning device for steam boilers. Background Technology

[0002] A steam boiler is a device that can generate steam. It is usually composed of oil-fired steam boilers, gas-fired steam boilers, and electric steam boilers. It uses oil, gas, or electricity to provide heat to heat the water inside the steam boiler and produce usable steam. However, during the use of steam boilers, a lot of scale will be generated on the inner wall of the boiler. If the scale is not cleaned, it will reduce the boiler's heat production efficiency.

[0003] Patent CN220750104U discloses a stain cleaning device for a steam boiler. By adjusting the rotation speed of the hollow shaft through a servo motor, the first scraper generates centrifugal force of different magnitudes. This allows the first scraper to exert pressure on the inner wall of the boiler, which is more conducive to the first scraper cleaning the stains on the inner wall of the boiler.

[0004] The existing technology described above only moves the first scraper horizontally when cleaning the inner wall of a steam boiler, without any vertical movement. This results in insufficient cleaning of the dirt on the inner wall of the boiler. Furthermore, in the existing technology, water carries the dirt out of the drain pipe during cleaning. After long-term use, the dirt can easily clog the drain pipe. Since the drain pipe is integrated with the boiler body, it is inconvenient to clean the dirt inside the drain pipe. In view of this, we propose a stain cleaning device for steam boilers. Utility Model Content

[0028] The specific implementation of this utility model will be described in detail below with reference to specific embodiments:

[0029] Reference Figures 1-4 A stain cleaning device for a steam boiler includes a boiler body 1. The boiler body 1 is characterized in that a water inlet 16 is provided at the top and a water outlet pipe 17 is installed at the bottom of the outer side. A drive mechanism is fixedly provided at the top of the boiler body 1. The bottom of the drive mechanism passes through the interior of the boiler body 1 via a rotating shaft 11. A crossbar 12 is fixed on the outer side of the rotating shaft 11. Both ends of the crossbar 12 are connected to scrapers 14. The crossbar 12 and the scrapers 14 are perpendicular to each other. A brush 15 is installed on the outer side of the scrapers 14.

[0030] The drive mechanism includes a housing 23. A motor 2 is fixed to the top of the inner wall of the housing 23. An output shaft 3 is installed in the middle of the motor 2. A vertical protrusion is provided at the bottom of the output shaft 3, which is movably engaged with a groove on the top of the rotating shaft 11. The output shaft 3 drives the rotating shaft 11 to rotate. A first gear 4 is fixed to the outside of the output shaft 3. Second gears 5 are symmetrically arranged on the left and right sides of the first gear 4. The first gear 4 and the second gear 5 are meshed, and the axis of the first gear 4 is perpendicular to the axis of the second gear 5. The first gear 4 and the second gear 5 transmit power. The middle position of the second gear 5 is fixedly connected to one end of the central shaft 6, and the other end of the central shaft 6... The bearing is rotatably connected to the side wall of the housing 23. A fixing plate 22 is fixed on the top of the housing 23. The fixing plate 22 is movably connected to the central shaft 6. A cam 7 is installed on the outside of the central shaft 6. A lifting plate 8 is set below the cam 7. A telescopic rod 9 is installed below the lifting plate 8. A spring 10 is sleeved on the outside of the telescopic rod 9. The lifting plate 8 and the furnace body 1 form a lifting installation structure through the cam 7. There are two cams 7 symmetrically arranged about the center line of the lifting plate 8 to ensure the force balance of the lifting plate 8 and make the lifting plate 8 move stably. A groove is set in the middle position of the lifting plate 8. The groove is movably engaged with the protrusion on the outside of the rotating shaft 11. The lifting plate 8 drives the rotating shaft 11 to move up and down.

[0031] Optionally, a valve knob 18 is fixed above the water outlet pipe 17. The water outlet pipe 17 is installed on the outer wall of the furnace body 1 by screws 19. A sealing ring 20 is provided between the water outlet pipe 17 and the outer wall of the furnace body 1 to prevent liquid leakage. A through hole 21 is opened on the side wall of the furnace body 1. After the furnace body 1 has been used for a long time, when dirt accumulates in the water outlet pipe 17, the water outlet pipe 17 can be disassembled for cleaning to avoid the accumulation of dirt and blockage of the water outlet pipe 17.

[0032] Optionally, a slider 13 is movably connected to the end of the crossbar 12, and the axis of the slider 13 coincides with the axis of the crossbar 12. The end of the slider 13 is fixed to the scraper 14. When the motor 2 is turned on, the slider 13 and the scraper 14 squeeze the brush 15 under the action of centrifugal force, which makes it easier to clean the dirt on the inner wall of the furnace body 1.

[0033] Optionally, screws 19 are distributed at equal angles on the side of the water outlet pipe 17, and the inner diameter of the water outlet pipe 17 is the same as the inner diameter of the through hole 21, so that the water carrying dirt can flow smoothly out of the furnace body 1.

[0034] The working principle of this utility model:

[0035] When using this device, turn on the motor 2 and pour the cleaning solution into the furnace body 1 through the inlet 16. The motor 2 drives the output shaft 3 to rotate. A first gear 4 is fixed on the outer side of the output shaft 3. A second gear 5 is meshed on the outer side of the first gear 4. A central shaft 6 is fixed in the middle of the second gear 5. A cam 7 is fixed on the outer side of the central shaft 6. While the output shaft 3 drives the rotating shaft 11 to rotate, the cam 7 also rotates and acts on the lifting plate 8, causing the lifting plate 8 to move vertically. Since a telescopic rod 9 and a spring 10 are installed below the lifting plate 8, the lifting plate 8 continuously performs repeated lifting and lowering movements. The rotating shaft 11 is movably connected in the middle of the lifting plate 8, so that while the rotating shaft 11 is rotating, it is also performing repeated vertical movements. In this way, the scraper 14 and the brush 15 can not only move in the horizontal rotation direction, but also move vertically, which can better clean the dirt on the inner wall of the furnace body 1 and achieve a comprehensive cleaning effect.

[0036] The water outlet pipe 17 is fixed to the side of the furnace body 1 by multiple screws 19, and a sealing ring 20 is tightly attached between the water outlet pipe 17 and the furnace body 1 to prevent liquid leakage. After the furnace body 1 has been used for a long time, when dirt accumulates in the water outlet pipe 17, the water outlet pipe 17 can be disassembled for cleaning to avoid dirt clogging the water outlet pipe 17.

However, it will be readily understood by those skilled in the art that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of the present invention.
