Automatic cleaning device for solar water heater

Abstract

The invention relates to an automatic cleaning device for a solar water heater. The automatic cleaning device for the solar water heater comprises a trolley, a distribution box, a circulating water tank, a steam water tank, a circulating water pump, a steam water pump, an electric heating evaporator, an electromagnetic descaling device, a trailer, a drying air pipeline, a steam pipeline, a constant-pressure exhaust valve, a filter, an air extracting pump, an electric heater and a connecting pipe. According to the automatic cleaning device for the solar water heater, the electromagnetic descaling technology is adopted, safety and high efficiency are achieved, corrosion for the water heater and damage to human body due to reagent residue after descaling of a traditional chemical reagent are avoided; and meanwhile, high-pressure steam is adopted to clean the surface of a heat collecting pipe, and drying with hot air is conducted; and the thermal decomposition function of steam is adopted, the sticky property of sediment and stain is quickly dissolved, so that the sediment and stain are separated from the heat collecting pipe, water consumption is reduced, and the surface of the heat collecting pipe is not damaged.

Description

technical field [0001] The invention belongs to the technical field of cleaning equipment, and in particular relates to an automatic cleaning device for a solar water heater. Background technique [0002] A solar water heater is a device that uses sunlight to heat water. Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters. Vacuum tube solar water heaters occupy 95% of the domestic market share. Vacuum tube household solar water heaters are composed of heat collecting tubes, water storage tanks, brackets and other related parts. The conversion of solar energy into heat mainly depends on the vacuum heat collecting tubes. Using the principle of hot water floating and cold water sinking, the water produces microcirculation to achieve the required hot water. Since the solar water heater needs to be placed in an open and unobstructed place, a large amount of dust and dirt will accumulate on the surface of the heat collecting tu...

Problems solved by technology

This patent uses a heat collecting tube with both ends connected to facilitate the discharge of the scale inside the heat collecting tube from the drain valve at the lower end. However, due to the small water flow inside the heat collecting tube, the scale will adhere to the inner wall of the heat collecting tube. This patent also needs to be done manually. Cleaning such as descaling
