Description

Technical Field

[0001] This utility model relates to the field of electric heater technology, and in particular to an electric heater with a self-cleaning function. Background Technology

[0002] Tank heaters play a vital role in numerous industrial production sectors and everyday life scenarios. They are widely used in industries such as chemical engineering, food processing, pharmaceuticals, petroleum refining, heating, and hot water supply, providing essential heat support for various processes. However, with prolonged use, impurities inevitably accumulate on the surface of the heating elements inside the tank heater. This negatively impacts the normal operation and performance of the equipment. In actual operation, the composition of substances inside the tank is complex and diverse. For example, in chemical production, materials may contain various chemical additives, reaction intermediates, and incompletely reacted raw materials; in the food processing industry, the tank may contain residual organic substances such as oils, proteins, and sugars; in heating systems, minerals and suspended solids in the water gradually adhere to the surface of the heating elements. These impurities continuously accumulate on the surface of the heating elements, forming a heat insulation layer.

[0003] Currently, cleaning the heating elements inside tank-type electric heaters mostly involves manual cleaning or simple rinsing. Manual cleaning requires operators to enter the tank and use brushes, cloths, and other tools to wipe the surface of the heating elements. This method is not only labor-intensive, but also difficult to thoroughly clean every surface of the heating elements due to the narrow space and complex structure inside the tank, easily leaving cleaning dead spots. Furthermore, during manual cleaning, operators may damage the heating elements due to improper handling, affecting the normal operation of the equipment. Therefore, an electric heater with a self-cleaning function has been proposed. Utility Model Content

[0014] (III) Beneficial Effects

[0015] This utility model provides an electric heater with a self-cleaning function, which has the following beneficial effects:

[0016] 1. This self-cleaning electric heater, through the setting of a cleaning mechanism and a spraying mechanism, when in use, activates a hydraulic rod on one side, which drives the cleaning disc at the end to reciprocate, so that several cleaning ports on the surface of the cleaning disc clean the surface of the heating tube. Combined with the cleaning liquid sprayed by the top atomizing nozzle, it can quickly clean the impurities attached to the surface of the heating tube without the need for manual cleaning, thus improving the cleaning efficiency of the equipment.

[0017] 2. This electric heater with self-cleaning function, through the setting of the sealing mechanism, can start the drive motor inside the motor box when the spraying mechanism is idle. The drive motor drives the sealing plate at the end to rotate inside the placement chamber, so that the top atomizing nozzle is separated from the main body cavity of the can-type electric heater. This prevents corrosive substances inside the main body of the can-type electric heater from corroding the atomizing nozzle, shortening the service life of the atomizing nozzle, or even affecting the normal functioning of the self-cleaning function.
