A device for descaling a single solar water heater receiving light glass tube

Abstract

The invention discloses a device for descaling a single solar water heater light-receiving glass tube, comprising a solution bucket, an electric heating tube, a heating switch, a water pump, a water pump switch, an output pipe, a return pipe, an output control valve, and an output and discharge valve , backflow control valve, backflow outflow valve, light-receiving glass tube, water inlet and outlet holes are opened on the side of the solution barrel, which are used to connect the water pump and return pipe respectively, and an electric heating tube is installed at the bottom of the solution barrel. The heating switch is used for 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 light-receiving glass tube is connected to the solution barrel through the return pipe, and the output control valve and the output discharge valve are installed on the output pipe. A backflow control valve and a backflow discharge valve are installed. The invention can realize descaling without dismantling the light-receiving glass tube, and this descaling method not only saves time and effort, but also saves money.

Description

technical field [0001] The invention relates to the technical field of descaling, in particular to a device for descaling a single solar water heater light-receiving glass tube. 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 cold water in the water heater will ...

Problems solved by technology

[0009] The object of the present invention is to propose a device for descaling a single solar water heater light-receiving glass tube, so as to solve the problem that the solar water heater light-receiving glass tube needs to be manually pulled one by one from the frame in the prior art. Disassembled by the method, and then poured acidic solution into the glass tube to dissolve the scale by manual pouring repeatedly, resulting in time-consuming, laborious and high cost problems
