Abstract

A solar water heater capable of automatically descaling comprises a support frame (1), an upper water storage tank (2) and a lower water storage tank (3). The upper water storage tank (2) and the lower water storage tank (3) are respectively and tightly covered by thermal insulation materials (10) and fixed on the support frame (1) and communicated with each other through a vacuum heat collecting pipe (4). A horizontal sliding bar (11) is fixed in the upper water storage tank (2). A brush disc (12) is sleeved on the sliding bar (11). A water inlet valve (7) is opened, a water outlet valve (8) is closed, new water is filled in the solar water heater, and along with the rising of a water level, a buoy (14) produces buoyancy and pulls the brush disc (12) to move towards one end via a pulley (13) through a pull line (16). The water inlet valve (7) is closed, a dirt discharging valve (6) is opened, various sediments and hazardous substances are discharged through a dirt discharging hole (5), and along with the dropping of the water level in the water heat, gravity produced by a heavy fall (15) drags the brush disc (12) to move towards the other end through the pull line (16). According to the solar water heater capable of automatically descaling, through the two processes of filling in the new water and discharging the dirt, the brush disc is dragged to clean the interior of the solar water heater, the dirt and the hazardous substances in the solar water heater are discharged, water quality of the solar water heater is improved, and the problem that the quality of water in the solar water heater does not reach the standard is solved.

Description

But the solar water heater of automatic desludging

Technical field:

The utility model is a kind of solar water heater, but or a kind of solar water heater of automatic desludging.

Background technology:

The solar water heater of current trend, because vacuum heat collection pipe lower end closed, make solar water heater in use, namely produce the harmful substances such as a large amount of precipitations, incrustation scale and nitrite, mostly be deposited in the solar vacuum heat-collecting pipe or depend on the storage tank inwall, especially in vast rural area, mountain area, domestic water directly comes from underground water mostly, quality of groundwater is harder, can produce more precipitation and harmful substance, making solar vacuum heat-collecting pipe really become a place of sheltering evil people and countenance evil practices, is the pollution sources in the solar water heater.

The utility model content:

Technical problem to be solved in the utility model is exactly the harmful substances such as various precipitations, incrustation scale and nitrite that solar water heater is in use produced, be deposited in the lower water tank by solar vacuum heat-collecting pipe up and down, regularly discharge by sordes-discharging valve again.Process at row's dirt and the new water of injection, by being located at cursory in the solar vacuum heat-collecting pipe that communicates up and down, and the heavily pendant that connects of cursory the below buoyancy and the gravity that produce, line passed through, be enclosed within the brush on the slide bar in the pulling in the storage tank, inwall to storage tank is cleaned with water, maximum possible solar water heater is cleaned, make solar water heater often keep clean, without dirt, unharmful substance, after injecting new water heating, enable to have a bath, heat up water, drink.The utility model has been discharged various impurity and harmful substance that solar water heater in use produces; the cleannes in the solar water heater have been improved; enlarged the scope of application that solar water heater comes; make that this clean energy resource of solar energy is more better to be utilized; be protection of the environment, more contribution has been made in energy-saving and emission-reduction.

For addressing the above problem, the technical solution adopted in the utility model is as follows: but the solar water heater of described automatic desludging comprises support, upper storage tank, lower water tank, the vacuum heat collection pipe that communicates up and down, enters (going out) water hole, advances (going out) water valve, mud hole, row's dirt valve.Establish a horizontal sliding bar in the upper storage tank, be fixed in the storage tank two ends, one brush is arranged on the slide bar, brush can horizontally slip at slide bar, the brush outer is fixed with bristle, upper, a pulley is fixed respectively at the lower water tank two ends, it is one cursory to establish in the vacuum heat collection pipe that communicates up and down, this is cursory can be one, also can be a plurality of cursory connectors, cursory below connects a heavy pendant, heavily pendant and cursoryly link together through pulley and brush by line respectively, the gravity of the buoyancy of cursory generation and heavily pendant generation is enough to spur brush side-to-side movement on slide bar, thereby upper storage tank inwall is cleaned.Upper and lower storage tank is separately fixed on the support, the volume of lower water tank should less than upper storage tank volume, in order to reduce the volume of lower water tank, lower water tank can be semicylinder.Upper and lower storage tank is tight with the insulation material parcel respectively, and be connected with the vacuum heat collection pipe that communicates up and down, be fixed on the support, establish a mud hole in the lower water tank lower end, and be connected with pipeline, establish a sordes-discharging valve on the pipeline, establish one along upper storage tank lower end and enter (going out) water hole, and be connected with pipeline, establish respectively a water intaking valve and an outlet valve on the pipeline.

For preventing the downward landing of solar vacuum heat-collecting pipe, the external diameter of vacuum heat collection pipe lower end and lower water tank coupling part should be less than the external diameter more than the coupling part.

During use, open outlet valve, close water intaking valve, the hot water in the solar water heater flows out along pipeline; Open water intaking valve, close outlet valve, new water injects in the solar water heater along pipeline, and by the cursory buoyancy that produces in the vacuum heat collection pipe, slides to an end by the pulling brush; Close water intaking valve, the dirty valve of the row of opening, in the incrustation scale in drain-solar water heater, precipitation and the harmful substance, the gravity by heavy pendant produces slides to the other end by line pulling brush, emptying after the dirty valve of the row of closing, the new water that reinjects heats.
