Description

Technical Field

[0001] The invention relates to the technical field of boiler cleaning, and in particular to a boiler scale cleaning device and a cleaning method. Background Art

[0002] A boiler is an energy conversion device. The energy input to the boiler includes chemical energy and electrical energy in the fuel. The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy. The original meaning of pot refers to a water container heated on fire, and furnace refers to a place where fuel is burned. The boiler consists of two major parts: the pot and the furnace. The hot water or steam generated in the boiler can directly provide the required thermal energy for industrial production and people's lives, or it can be converted into mechanical energy through a steam power device, or the mechanical energy can be converted into electrical energy through a generator. After a boiler has been used for a long time, a large amount of scale will adhere to the inner wall of the boiler. Due to the poor thermal conductivity of scale, it will hinder heat conduction, resulting in prolonged heating time, increased energy consumption, and reduced water storage capacity of the boiler.

[0003] The existing boiler scale is mainly cleaned by chemical agents, and some boilers are descaled by physical scraping. For example, Chinese patent announcement number CN219063493U discloses a "boiler scale cleaning device", which positions the device at the boiler mouth by a limit block, and then rotates the adjustment bolts threadedly installed at both ends of the two sets of limit blocks, so that the adjustment bolts slowly penetrate into the limit rod, thereby driving the positioning rod inside the limit rod to move, driving the clamping block to move, and stopping the rotation of the adjustment bolt when the clamping block clamps the outer end of the boiler mouth, so that the device can be fixed on the boiler, and the cleaning rod is pushed to move on the clamping strip, and stops when it touches the inner wall of the boiler, so that the cleaning block at the front end of the cleaning rod contacts the inner wall, which is convenient for cleaning;

[0004] In actual use, when the cleaning device is used to clean the boiler, it is inconvenient to clean due to the large size of the boiler. If the size of the cleaning device is directly increased so that it can clean the entire boiler at one time, the cleaning device will be large in size and weight, which will be inconvenient to move and calibrate, and the cleaning difficulty will be increased. If the cleaning device is pushed to gradually wash the inner wall of the boiler, the burden on the operator and the difficulty of operation will be increased, and the cleaning efficiency will be reduced. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art, such as large size and weight of large cleaning devices, which are not conducive to movement and calibration, and promote small cleaning devices to gradually clean the inner wall of the boiler, which increases the burden on operators and reduces cleaning efficiency. A boiler scale cleaning device and cleaning method are proposed.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0015] Furthermore, the counterweight chamber and the cleaning assembly are respectively arranged on both sides of the lifting assembly, a telescopic rod is fixedly arranged on the mobile platform, and an output end of the telescopic rod is fixedly connected to the power box.

[0016] Furthermore, the cleaning assembly includes a mounting frame, a cleaning roller is disposed on the mounting frame, the mounting frame is fixedly connected to the sleeve, and a scraper and a brush are disposed on the cleaning roller.

[0017] A boiler scale cleaning method comprises the above-mentioned boiler scale cleaning device, and further comprises the following steps:

[0018] S1. Push the mobile platform to the vicinity of the boiler to be cleaned, open the end cover of the boiler to be cleaned, and expose the inner cavity of the boiler;

[0020] S3, the first motor drives the gear to rotate, and the driving sleeve drives the cleaning assembly and the cleaning brush to rotate to clean the inner wall of the boiler;

[0021] S4. When the sleeve drives the cleaning assembly to rotate, it cooperates with the cylindrical cam, so that the sleeve and the cleaning assembly rotate and move back and forth simultaneously, thereby cleaning the entire inner wall of the boiler.
