Abstract

The invention relates to a solar water heater with an automatic scale removing function. The solar water heater comprises a support 1, an upper water storage tank 2 and a lower water storage tank 3, wherein the upper and lower water storage tanks are respectively and tightly wrapped with a heat insulation material 10, are fixedly arranged on the support 1, and are communicated by a vacuum heat collecting pipe 4 which is communicated with upper and lower parts, and a horizontal sliding rod 11 is fixedly arranged in the upper water storage tank 2; and a brush disc 12 is sleeved on the sliding rod 11. A water inlet valve 7 is opened, and a water outlet valve 8 is closed, so that new water is filled into the solar water heater, and thus a buoy 14 generates buoyancy with the rise of water level, and the brush disc 12 is pulled by a guy 16 through a pulley 13 to move towards one end; the water inlet valve 7 is closed, and a scale discharge valve 6 is opened, so that various deposits and harmful substances are discharged through a scale discharge hole 5, and thus a counter weight 15 generates gravity with the drop of water level in the solar water heater, and the brush disc 12 is pulled by the guy 16 to move towards the other end. Through the two processes of new water filling and scale removing, the brush disc is pulled to clean the inside of the solar water heater, so that the scale and harmful substances are discharged, and thus the quality of water in the solar water heater is improved, and the problem that the quality of water in the solar water heater is substandard is solved.

Description

But the solar water heater of automatic desludging

Technical field:

The present invention is a kind of solar water heater, but a kind of solar water heater of automatic desludging espespecially.

Technical background:

The solar water heater of current trend, due to the vacuum heat collection pipe lower end closed, solar water heater in use, produce the harmful substances such as a large amount of precipitations, incrustation scale and nitrite, mostly be deposited in 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, make the vacuum heat collection pipe of solar water heater really become a place of sheltering evil people and countenance evil practices, become the pollution sources in solar water heater.

The content of invention:

Technical problem to be solved by this invention, the harmful substances such as the various precipitations, incrustation scale and the nitrite that exactly solar water heater are in use produced, be deposited in lower water tank by the solar vacuum heat-collecting pipe communicated up and down, more regularly discharge by sordes-discharging valve.Process at row's dirt and the new water of injection, by being located at cursory in the solar vacuum heat-collecting pipe communicated up and down, and buoyancy and the gravity that heavily pendant produces of the connection of cursory below, pull in upper storage tank and be enclosed within the brush on slide bar by line, 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 for washing dish, wash the dishes, drinking.The present invention can discharge various impurity and the 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, for protection of the environment, save to reduce discharging and made more contribution.

For addressing the above problem, the technical solution used in the present invention 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 communicated 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 upper storage tank, be fixed in the storage tank two ends, one brush is arranged on litter, and brush can horizontally slip on litter, and the brush outer is fixed with bristle, fix respectively a pulley at upper and lower storage tank two ends, it is one cursory in the vacuum heat collection pipe communicated up and down, to establish, and this is cursory can be one, can be also 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 buoyancy of cursory generation and the gravity that heavily pendant produces are enough to pull brush side-to-side movement on litter, thereby upper storage tank inwall is cleaned.Upper and lower storage tank is separately fixed on support, the volume of lower water tank should be less than storage tank volume, in order to reduce the volume of lower water tank, lower water tank should be semicylinder.Upper and lower storage tank is tight with the insulation material parcel respectively, and be connected with the vacuum heat collection pipe communicated up and down, establish a mud hole in the lower water tank lower end, and be connected with pipeline, establish row's dirt valve on 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 pipeline.

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

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

Fig. 1 is structural representation of the present invention.

Fig. 2 is that the A of Fig. 1 is to view.

Fig. 3 is the structural representation of the vacuum heat collection pipe that communicates up and down.

Fig. 4 is the structural representation of sliding plate.

The specific embodiment:

But as shown in Figure 1 be the solar water heater of automatic desludging of the present invention, comprise support 1, upper storage tank 2, lower water tank 3, upper lower water tank is tight with insulation material 10 parcels respectively, be fixed on support 1, and be connected with the vacuum heat collection pipe 4 communicated up and down, the interior horizontal litter 11 of fixing of upper storage tank 2, cover one brush 12 on litter 11, open water intaking valve 7, close outlet valve 8, new water injects in solar water heater, along with water level rises, cursory 14 produce buoyancy, by bracing wire 16, through pulley 13, pulls brush 12 to an end motion; Close water intaking valve 7, the dirty valve 6 of the row of opening, various precipitations and harmful substance are discharged by mud hole 5, along with water level descends, heavily fall 15 gravity that just produce, by bracing wire 16, pull brush 12 to other end motion, in the reciprocating process of brush, upper storage tank inwall is cleaned.
