[0002] Special equipment boilers are relatively dangerous boilers. Generally, professional staff are employed to clean the boilers. Professional staff enter the boiler to clean it, which is troublesome and increases the workload and cost of the staff. Therefore, a descaling device is added to the water inlet of the boiler to purify the incoming water and avoid the formation of scale in the boiler equipment. However, the filter in the descaling device currently only filters the water quality, and the impurities filtered out need to be cleaned later, which causes inconvenience to the use.

[0006] Further configuration: cleaning rollers are arranged at least three times, and the cleaning rollers are evenly distributed outside the filter screen.

[0007] It is further arranged that the power transmission component comprises a driving gear fixed on the central shaft, a sub-gear is fixed on the cleaning roller, and the driving gear meshes with the sub-gear to rotate.

[0008] Further configuration: the length of the central axis is greater than the length of the filter screen.

[0009] It is further arranged that: the central shaft is rotatably connected with the partition, and a groove for limiting the cleaning roller is arranged on the partition.

[0010] It is further arranged that the cleaning roller rotates around the filter screen, and the filter screen is rotatably connected to the limit ring.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] Through the setting of the cleaning mechanism, when water flows through the descaling device body and enters the boiler, the water flow pushes the impeller to drive the central axis to rotate, so that the central axis drives the cleaning roller to rotate itself through the power transmission component and rotates around the central axis at the same time, thereby removing impurities filtered on the outside of the filter and dropping them into the drain pipe, so that the filter can be cleaned during use, thereby improving the convenience of use.
