A device for simultaneously descaling a solar water heater light-receiving glass tube and a water storage tank

Abstract

The invention discloses a device for descaling a light-receiving glass tube and a water storage tank of a solar water heater at the same time, comprising a solution tank, an electric heating tube, a heating switch, a water pump, a water pump switch, an output pipe, a return pipe, an output control valve, an output Outlet valve, backflow control valve, backflow outflow valve, light-receiving glass tube, solar water heater storage barrel, and water outlet and inlet holes are opened on the side of the solution barrel, which are used to connect the water pump and return pipe respectively. The bottom of the solution barrel is installed with The electric heating tube, the heating switch is used to control the electric heating tube, the water pump switch is used to control the water pump, the light-receiving glass tube is connected to the water pump through the output pipe, the storage tank of the solar water heater is connected to the solution tank through the return pipe, and the output control valve is installed on the output pipe And the output discharge valve, a return control valve and a return discharge valve are installed on the return pipe. The invention can realize descaling without dismantling the light-receiving glass tube, and the descaling method saves time, labor and money.

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.
