Description

Technical Field

[0001] This utility model relates to the field of boiler maintenance technology, specifically to a heating boiler with an internal wall cleaning mechanism. Background Technology

[0002] A heating boiler is a device that heats water into hot water or steam by burning fuels (such as natural gas, coal, biomass, etc.) or using electricity to provide heat energy for buildings, industrial processes, or district heating systems. It is a core component of heating systems, hot water supply, or industrial heat sources. After long-term use, existing heating boilers suffer from severe scale buildup on their inner walls, leading to reduced thermal efficiency and potentially serious safety accidents.

[0003] A search revealed a utility model patent with publication number CN213453594U, which discloses a boiler for thermal power generation with an internal wall cleaning mechanism. The boiler includes a furnace body and a water tank. A support column is fixedly connected to the bottom end of the furnace body. A second motor is fixedly connected to the right end of the furnace body, and a spiral rod is fixedly connected to the end of the main shaft of the second motor, with the spiral rod rotatably connected to the furnace body. A fan is fixedly connected to the left end of the furnace body, and the fan is connected to the spiral rod. A second spring is fixedly connected to the inner side of the bottom end of the furnace body, and a retaining plate is fixedly connected to the other end of the second spring. A furnace bar is slidably connected to the right end of the retaining plate. In this utility model, the scraper, spiral rod, furnace bar, second spring, ball bearings, and eccentric wheel are used to perform secondary cleaning of the scale on the inner wall of the water tank, accelerating the transfer of heat energy in the water tank, increasing the oxygen content in the furnace body, thus speeding up the thermal power generation. The furnace bar is also easy to replace and maintain, extending the service life of the device.

[0004] The aforementioned patents only use scrapers, motors, and threaded rods to scrape and clean the inner wall of the boiler. However, some scale that has been attached for many years is difficult to remove by scrapers alone, making it inconvenient to thoroughly clean the inner wall of the boiler.

[0005] Therefore, it is necessary to invent a heating boiler with an internal wall cleaning mechanism to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a heating boiler with an internal wall cleaning mechanism. The mechanism uses a motor, sprocket, rotating rod, scraper, and wire brush to wipe and scrape the internal wall. At the same time, the design of the water pump and rotating rod allows for the spraying of a cleaning and softening agent onto the internal wall while cleaning, achieving the effect of softening scale and thoroughly cleaning the internal wall. This solves the problem of incomplete cleaning of the boiler internal wall in existing technologies, which reduces thermal efficiency and increases safety hazards.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a heating boiler with an internal wall cleaning mechanism, comprising a support plate, a heating furnace fixedly connected to the upper end of the support plate, a steam furnace fixedly connected to the upper end of the heating furnace, the heating furnace communicating with the interior of the steam furnace, a heating pipe disposed in the internal interlayer of the heating furnace, a heating port fixedly connected through the interior of the steam furnace, the heating port communicating with the interior of the steam furnace; a connecting plate fixedly connected to the side wall of the steam furnace, a motor fixedly connected to the upper end of the connecting plate, a sprocket one fixedly connected to the output end of the motor via a coupling, a chain sleeved on the outside of the sprocket one, a rotating rod rotatably connected through the interior of the steam furnace, a sprocket two fixedly connected to the side wall of the rotating rod, a chain sleeved on the outside of the sprocket two, a scraper fixedly connected to the side wall of the rotating rod, and a wire brush fixedly connected to the side wall of the rotating rod.

[0008] Preferably, a water pump is fixedly connected to the upper end of the support plate, and a water tank is fixedly connected to the upper end of the support plate. The input end of the water pump is connected to the inside of the water tank. A connecting pipe is rotatably connected through the inside of the rotating rod. The connecting pipe connects the output end of the water pump to the inside of the rotating rod. Two nozzles are fixedly connected through the inside of the scraper. The scraper connects the rotating rod to the inside of the two nozzles.

[0009] Preferably, an ultrasonic transducer is fixedly connected through the interior of the heating furnace, and the output end of the ultrasonic transducer is connected to the interior of the heating furnace.

[0010] Preferably, a water inlet is fixedly connected through the interior of the heating furnace, the water inlet being connected to the interior of the heating furnace, and a drain outlet is fixedly connected through the interior of the heating furnace and the support plate, the drain outlet being connected to the interior of the heating furnace.

[0011] Preferably, a liquid replenishment port is fixedly connected through the inside of the water tank, and the liquid replenishment port communicates with the inside of the water tank.

[0012] Preferably, the lower end of the support plate is fixedly connected to multiple support columns.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. When the boiler needs cleaning, the drive motor drives the first sprocket to rotate. Under the action of the chain, the first sprocket rotates, which in turn drives the second sprocket to rotate. The second sprocket rotates, which in turn drives the rotating rod to rotate. The rotating rod rotates, which in turn drives the scraper and wire brush to rotate, cleaning and scraping away the scale on the inner wall. When cleaning and scraping the heating furnace, the water pump is started. The water pump draws the cleaning and softening liquid inside the water tank and pumps it into the connecting pipe. Through the connecting pipe, it enters the rotating rod, then the scraper, and finally the nozzle. Finally, it is sprayed out through the nozzle to spray the inner wall, cleaning and softening the dirt attached to the inner wall.

[0015] 2. When cleaning the inside of the heating furnace, turn on the ultrasonic transducer. The ultrasonic transducer generates high-frequency vibrations to loosen the scale on the inner wall of the heating furnace. The ultrasonic transducer can also be turned on before cleaning to shake off the scale adhering to the inner wall of the heating furnace and prevent the scale from accumulating on the inner wall.
