Technical Field

[0001] The utility model relates to the technical field of drug adding and descaling equipment, in particular to automatic drug adding and descaling equipment. Background Art

[0002] Due to the high chlorine content in the blast furnace gas of the steel plant, coupled with the hot climate in summer, chlorine-containing salts are easily precipitated and deposited on the surface of the gas heat exchanger, which can easily cause salt accumulation in the boiler's gas heater equipment, seriously affecting the gas flow capacity and even the unit's load capacity. Therefore, in order to ensure the normal use of the boiler, a special dosing and descaling device is needed to remove the salt accumulation.

[0003] In the Chinese utility model patent with the announcement number CN218763310U, an automatic dosing and descaling device is disclosed. The device can adjust the direction of the descaling liquid spraying through the adjustment structure, so that the liquid can be sprayed all-round inside the device, which not only enhances the descaling ability but also improves the descaling efficiency. With respect to the above-mentioned related technologies, the inventor believes that there are the following defects:

[0004] In actual use, the device requires the servo motor and the rotary motor to operate simultaneously to achieve the adjustment of the all-round spraying of the liquid medicine, which not only increases the energy consumption of the device, but also due to the continuous spraying of the liquid medicine, the same position will be exposed to a large amount of liquid medicine in a short period of time, which is easy to cause waste of liquid medicine due to untimely response. For this reason, we provide an automatic dosing and descaling equipment. Utility Model Content
