The thermal-collecting tube of solar water heater scale prevention device
The utility model relates to a kind of member, parts or annex of solar thermal collector, is specifically related to a kind of antiscale formula thermal-collecting tube of solar water heater.
Now, the thermal-collecting tube type solar water heater is used widely.The energy that this product in use can effectively utilize the sun very much becomes hot water with cold water, and no longer the additive decrementation energy is subjected to the consumer acceptance deeply, and pollution-free, and spirit meets the requirement of world environmental protection organization.But the thermal-collecting tube type solar water heater is along with the growth of service life, and its collector tube inner wall is sediment incrustation gradually, influences Heat-collecting effect and water quality, have to during cleaning thermal-collecting tube is taken off one by one, not only time-consuming taking a lot of work, past contact meeting causes leaks, and damages vacuum heat collection pipe etc.
The utility model content
The purpose of this utility model is to provide and a kind of thermal-collecting tube of solar water heater scale prevention device, the incrustation scale in the thermal-collecting tube effectively can be discharged, and reaches the effect of thermal-collecting tube antiscale.
For achieving the above object, the technical solution of the utility model is: the thermal-collecting tube of solar water heater scale prevention device, the body that comprises thermal-collecting tube, body inserts in the storage tank of solar water heater, body is airtight the connection with the water storage tank wall, is provided with T shape siphon pipe in the described body, and siphon pipe is divided into siphon end and water side, described siphon end extends the bottom of body, and described water side is stretched in the storage tank and by the thermal-collecting tube oral area and held.
When adopting technique scheme, because be provided with siphon pipe in thermal-collecting tube, like this, the water in the thermal-collecting tube can flow in the siphon pipe under siphonage, enters in the storage tank by siphon pipe.Because siphonal siphon end extends the bottom of thermal-collecting tube, adds siphonage, the dirt in the thermal-collecting tube is sucked in the storage tank.And, compare thermal-collecting tube, the incrustation scale in the storage tank is better removed, and like this, just can reach the purpose of antiscale in the thermal-collecting tube.
Further, in order to improve the inflow of siphon end, described siphonal siphon end is 45 ° of angles.Adopt 45 ° of angles to increase the bore of siphon end, increased siphonal water absorption.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model thermal-collecting tube of solar water heater scale prevention device embodiment.
Fig. 2 is the partial enlarged drawing of water side among Fig. 1;
Fig. 3 is the partial enlarged drawing of siphon end among Fig. 1.
The specific embodiment
As shown in Figure 1, the direction of arrow is represented water (flow) direction among the figure.The utility model thermal-collecting tube of solar water heater scale prevention device on the whole with the prior solar water heater structural similarity, repeats part and does not give unnecessary details at this.Main distinction point is arranged on the thermal-collecting tube 1 on the roof, has all inserted a T shape siphon pipe 3 in the body of thermal-collecting tube 1 and the storage tank 2.Siphon pipe 3 is divided into the water side 4 of siphon end 5 and T shape, described siphon end 5 is 45 ° of angles and the bottom that extends thermal-collecting tube 1, water side 4 is stretched in the storage tank 2 and is held in the palm in the oral area of thermal-collecting tube 1, when the thermal-collecting tube 1 of vacuum under illumination during thermal-arrest, water generates microcirculation in storage tank 2 and the thermal-collecting tube 1, hot water flows upward in the storage tank 2, cold water flows to the bottom of thermal-collecting tube 1 downwards, under the effect of T shape siphon pipe 3, can produce siphonage, it is the bottom incrustation scale of thermal-collecting tube 1, dirt can flow upward to the bottom of storage tank 2 along T shape siphon pipe 3, thereby reaches the effect of removing the incrustation scale in the thermal-collecting tube 2.
Above-described only is preferred implementation of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
