Problems solved by technology

However, because the traditional solar water heater has no cleaning device, a large amount of scale will accumulate in the water storage tank as the use time increases. If it is not cleaned in time, the scale in the water storage tank will accumulate more and more, which not only affects the water supply of the water storage tank As a result, the water temperature in the water storage tank will be heated slowly; at the same time, because the water storage tank of the solar water heater is exposed to the outside, the drain pipes exposed to the outside are very easy to freeze, affecting users to use hot water, and more seriously, the water pipes will freeze. cracked, wasting a lot of water

Embodiment 1

[0050] Such as Figure 1 to Figure 8 Shown, the cleaning method of a kind of solar water heater scale of the present invention comprises the following steps:

[0051] 1) Open the valve on the drain pipe 10 to discharge the water in the water storage tank 2;

[0052] 2) Open the valve and the water pump on the water inlet pipe 1, use the water pump to feed high-pressure water into the water inlet pipe 15, and the high-pressure water enters the fixed box 3, and drives the first blade 35 and the second blade 36 to rotate in the fixed box 3, Thereby, the rotating shaft 12 is driven to rotate in the fixed 3, so that the scraper 4 cleans the scale on the inner wall of the water storage tank 2;

[0053] 3) The water acting on the first vane 35 and the second vane 36 is then sprayed upwards onto the inner wall of the water storage tank 2 through the outlet pipe 21, and the scale scraped loose by the scraper 4 is washed from the inner wall to the inner bottom of the water storage tank...

Embodiment 2

[0061] On the basis of Embodiment 1, the rotating shaft 12 is also provided with two movable blocks 11, and the two ends of the arc-shaped plate 8 are respectively connected with the two movable blocks 11, and the movable block 11 is provided with a The connecting hole 39 is provided, and the rotating shaft 12 is inserted into the connecting hole 39 , and the movable block 11 can move on the rotating shaft 12 along the axial direction of the rotating shaft 12 .

Embodiment 3

[0063] On the basis of Embodiment 2, guide plates 7 are provided on both sides of the outer circumferential wall of the rotating shaft 12, and the guide plates 7 are distributed along the axial direction of the rotating shaft 12. Both sides of the inner wall of the connecting hole 39 are provided with guiding The plate 7 matches the guide groove 40, and the guide plate 7 is located in the guide groove 40.

Description

technical field [0001] The invention relates to the technical field of solar water heaters, in particular to a method for cleaning scales of solar water heaters. 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. Solar water heaters are composed of vacuum heat collecting tubes, stainless steel water tanks and brackets. They are a major industry in the application of solar energy achievements. ...
