A vacuum tube for a solar water heater

Abstract

The invention relates to the field of solar water heaters, in particular to a vacuum pipe of a solar water heater. The vacuum pipe comprises a cover glass pipe, an inner glass pipe, a rotation motor and a vibration washing device. The cover glass pipe and the inner glass pipe are two concentric circular glass pipes, the portion between the cover glass pipe and the inner glass pipe is vacuum, a vertical separation plate for dividing the inner glass pipe into a left part and a right part is arranged inside the inner glass pipe, and the left part and the right part are communicated through a pressure valve installed at the bottom of the vertical separation plate; the rotation motor is arranged at the bottom of the cover glass pipe; the vibration washing device comprises a gelled pill, a high pressure water pump and a discharging pipe, the gelled pill is arranged at the position of a water outlet of the high pressure water pump, the water outlet of the high pressure water pump is connected to the upper end of the inner glass pipe, the gelled pill is driven by the water pressure of the high pressure water pump to enter the inner glass pipe to continuously collide the inner wall of the inner glass pipe, and the discharging pipe is connected to the lower end of the inner glass pipe. According to the vacuum pipe of the solar water heater, cold water is prevented from entering the vacuum pipe, pipe explosion is avoided, and meanwhile incrustation in the pipe are easily removed.

Description

technical field [0001] The invention relates to the field of solar water heaters, in particular to a vacuum tube of the solar water heater. Background technique [0002] Today, when the global energy situation is tense and climate warming seriously threatens economic development and people's life and health, all countries in the world are seeking new energy alternative strategies in order to achieve sustainable development and gain an advantage in future development. Solar energy has become the focus of attention due to its obvious advantages such as cleanliness, continuous flow, and safety. In the development of the solar energy industry, the heat conversion technology of solar water heaters is undoubtedly the most mature, but the heating method has the following problems: on the one hand, when there is no water in the vacuum tube, once cold water enters, there is a problem of blowing the tube; on the other hand , The heat of the vacuum tube is very large, and scale is eas...
