Scale remover spraying device for vacuum tube of solar water heater

Abstract

The invention provides a scale remover spraying device for a vacuum tube of a solar water heater, and relates to the field of cleaning of solar water heaters. The scale remover spraying device for the vacuum tube of the solar water heater comprises an outer barrel and a top disc, the upper end of the outer barrel is rotationally inserted into the bottom face of the top disc, a liquid storage pipe is arranged in the outer barrel, a pushing spring is fixedly connected to the upper surface of the liquid storage pipe, the upper surface of the pushing spring is fixedly connected with the bottom face of the top disc, a telescopic pipe is arranged in the pushing spring, the bottom face of the telescopic pipe is fixedly connected with the upper end face of a liquid storage pipe, a water inlet is formed in the upper end face of the liquid storage pipe, and a water inlet pipe fixedly penetrates through the upper surface of the top disc. According to the scale remover spraying device for the vacuum tube of the solar water heater, by arranging the liquid storage pipe, a push disc, a push rod, a sliding groove, a transmission rod and a liquid spraying plate, the effect that a scale remover is evenly sprayed to the inner wall of a vacuum pipe when the liquid spraying plate rotates is achieved, and the problems that at present, the number of added scale remover is too large, and the scale remover cannot make even contact with scale on the inner wall of a pipeline are solved.

Description

technical field [0001] The invention relates to the field of cleaning solar water heaters, in particular to a vacuum tube descaling agent spraying device for solar water heaters. Background technique [0002] A solar water heater is a heating device that converts sunlight energy into heat energy, and heats water from low temperature to high temperature, so as to meet the hot water use in people's life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters according to their structural forms, mainly vacuum tube solar water heaters. [0003] After the solar vacuum tube has been used for a period of time, a lot of scale adheres to the inner wall of the tube. When the scale accumulates too much, it will affect the normal use of the solar water heater. Therefore, it is necessary to regularly clean the scale inside the solar vacuum tube. When cleaning the scale, it is necessary to use descaling Currently, when addin...
