Description

Technical Field

[0001] The utility model relates to the technical field of boiler cleaning, in particular to an auxiliary boiler cleaning device. Background Art

[0002] The boiler mainly consists of two parts: the pot and the furnace. The hot water or steam generated in the boiler can directly provide the required heat energy for industrial production and people's lives. During the use of the boiler, since it requires fuel for combustion, a large amount of carbon deposits will be stuck on the inner wall of the boiler flue, so a cleaning device is needed to clean the inner wall of the flue.

[0003] A boiler auxiliary cleaning device with publication number CN218972690U is disclosed. After the device is placed into the filling port opened at the top of the boiler body, the arc scraper and the cleaning brush plate are both fitted with the inner wall of the boiler body under the operation of the electric telescopic rod. The operation drive motor rotates to drive the rotating shaft to rotate. The rotation of the rotating shaft drives the arc scraper and the cleaning brush plate to make circular motion with the rotating shaft. The arc scraper can scrape off impurities adhering to the inner wall of the boiler body, and the scraping surface can be cleaned under the brushing of the cleaning brush plate. During the cleaning process, the hydraulic rod is operated to drive the cleaning assembly to move up and down until the cleaning work of the boiler body is completed. This method can effectively ensure the long-term use of the boiler body.

[0004] However, in actual use, since the cleaning brush and the scraper are fixedly installed on the fixed block and the output end of the electric telescopic rod, it is not convenient to replace the cleaning brush and the scraper. Therefore, when the cleaning brush needs to be replaced due to severe wear of the scraper or dirty after long-term use, it becomes more troublesome, which greatly reduces the convenience of the device.

[0005] Therefore, a boiler auxiliary cleaning device is designed and produced here to solve the problem that it is inconvenient to replace the cleaning brush and the scraper. Utility Model Content

Therefore, when the cleaning brush and the scraper need to be replaced due to severe wear of the scraper or the dirty cleaning brush after long-term use, it is rather troublesome, which greatly reduces the convenience of the device. Therefore, a boiler auxiliary cleaning device is proposed.

[0007] The technical solution adopted by the utility model to solve the technical problem is: a boiler auxiliary cleaning device, comprising a boiler body, a limiting plate is arranged on the top of the boiler body, the top of the limiting plate is fixedly connected to a driving motor, the output end of the driving motor is fixedly connected to a rotating rod through the limiting plate, a pair of electric push rods are fixedly connected to the outer wall of the rotating rod, both sides of the rotating rod are respectively provided with an L-shaped cleaning brush and an L-shaped scraper, the output ends of the electric push rods are fixedly connected to a fixing box, the L-shaped cleaning brush and the L-shaped scraper are fixedly connected to a pair of fixing blocks on the side walls of the fixing box, the fixing box is internally slidably connected to the limiting rod, the side walls of the limiting rod are fixedly connected to a pair of L-shaped rods, the bottom of the fixing block is provided with a limiting groove, the top of the L-shaped rod passes through the fixing groove and is inserted into the limiting groove, and a spring is fixedly connected between the inner wall of the fixing box and the limiting rod;

[0008] By pulling the pull rod downward, the limit rod is driven to slide downward, thereby driving the L-shaped rod to slide downward and out of the limit groove, thereby releasing the position restriction on the fixed block. At the same time, the spring is stretched, and the L-shaped cleaning brush or L-shaped scraper can be pulled to drive the fixed block to slide out of the fixed groove, so that the L-shaped cleaning brush or L-shaped scraper can be replaced, thereby improving the convenience of the device.

[0009] Preferably, a pull rod is fixedly connected to the side wall of the limit rod and passes through the fixed box. The limit rod is pulled by the pull rod to quickly release the position restriction on the fixed block, thereby improving the replacement efficiency of the device.

[0010] Preferably, the side walls of the rotating rod are respectively provided with a lower cleaning brush and a lower scraper, and the bottom side walls of the L-shaped cleaning brush and the L-shaped scraper are fixedly connected with a sliding block, and the side walls of the lower cleaning brush and the lower scraper are provided with a sliding groove adapted to the sliding block, and the sliding block is slidably connected inside the sliding groove. By arranging the lower cleaning brush and the lower scraper, it is convenient to clean the bottom end of the interior of the boiler body, thereby further improving the cleaning efficiency of the device, and when the electric push rod pushes the fixed box, the L-shaped cleaning brush and the L-shaped scraper to move, the sliding block is driven to slide inside the sliding groove to avoid hindering the extension and retraction of the L-shaped cleaning brush and the L-shaped scraper.

[0011] Preferably, both sides of the rotating rod are provided with card slots, and the lower cleaning brush and the lower scraper are fixedly connected to the side close to the card blocks that are adapted to the card slots. The lower cleaning brush and the lower scraper are inserted into the card slots through the card blocks, thereby improving the stability of the lower cleaning brush and the lower scraper during rotation.

[0012] Preferably, the outer wall of the rotating rod is fixedly connected to two pairs of guide cylinders, and the side walls of the two pairs of guide cylinders are slidably connected to guide rods. The guide rods are fixedly connected to the side wall of the fixed box on the far side.
