Device for simultaneously descaling light receiving glass tube and water storage drum of solar water heater

Abstract

The invention discloses a device for simultaneously descaling a light receiving glass tube and a water storage drum of a solar water heater. The device comprises a solution drum, an electric heating pipe, a heating switch, a water pump, a water pump switch, an output pipe, a backflow pipe, an output control valve, an output discharging valve, a backflow control valve, a backflow discharging valve, the light receiving glass tube and a solar water heater water storage drum, wherein a water outlet hole and a water inlet hole are formed in the side surface of the solution drum, and are correspondingly connected to the water pump and the backflow pipe; the electric heating pipe is mounted at the bottom of the solution drum; the heating switch is used for controlling the electric heating pipe; the water pump switch is used for controlling the water pump; the light receiving glass tube is connected with the water pump through the output pipe; the solar water heater water storage drum is connected with the solution drum through the backflow pipe; the output control valve and the output discharging valve are mounted on the output pipe; the backflow control valve and the backflow discharging valve are mounted on the backflow pipe. The device disclosed by the invention can realize descaling without detaching the light receiving glass tube; the descaling mode is time-saving, labor-saving and cost-saving.

Description

technical field [0001] The invention relates to the technical field of descaling, in particular to a device for simultaneously descaling a solar water heater light-receiving glass tube and a water storage tank. Background technique [0002] The basic structure of a solar water heater consists of a light-receiving vacuum glass tube (hereinafter referred to as light-receiving glass tube), a water storage bucket and other connecting pipes. [0003] The light-receiving glass tube is the most critical and fragile main part of the entire water heater, and it is indispensable. Under normal circumstances, the water in the light-receiving glass tube heats up under the action of solar radiation and enters the water storage tank through the connection between the glass tube and the water storage tank, and the slightly cooler water in the water storage tank also enters the light-receiving tank under the action of convection. The glass tube is heated by solar energy, so that all the col...

Problems solved by technology

[0009] The object of the present invention is to propose a device for descaling a solar water heater light-receiving glass tube and a water storage tank at the same time, to solve the problem that the above-mentioned prior art cannot simultaneously descale a solar water heater light-receiving glass tube and a water storage tank, and the solar water heater The descaling of the light-receiving glass tubes needs to be removed from the frame one by one by manual pulling, and then the acidic solution is poured into the glass tubes to dissolve the scales manually, resulting in time-consuming, labor-intensive, and high-cost problems.
