Description

Technical Field

[0001] The utility model belongs to the technical field of solar water heater water tanks, and particularly relates to a water tank for a solar water heater with a filtering structure. Background Technique

[0002] A solar water heater is a heating device that converts solar energy into heat energy, heating water from a low temperature to a high temperature to meet the hot water use of people in life and production. It can be divided into a vacuum tube solar water heater and a flat plate solar water heater according to the structural form, mainly the vacuum tube solar water heater. A household vacuum tube solar water heater is composed of a heat collecting tube, a water storage tank, a bracket and other related parts, which converts solar energy into heat energy. In the prior art, the water tank of the solar water heater is easily impacted by rainwater during use, and the structure of the water tank is easily corroded and rusted quickly due to factors such as rainwater.

[0003] For this reason, a solar water heater water tank with a purification device with the publication number of "CN219243933U" includes a box body. On both sides of the upper surface of the box body, a protection mechanism is symmetrically and fixedly installed. The protection mechanism includes a threaded pipe seat. In the middle of the upper surface of the threaded pipe seat, a telescopic rod is installed through. In the front surface of the threaded pipe seat, a fastening bolt is installed through. The upper end of the telescopic rod is fixedly installed with a shielding plate. On the front surface of the telescopic rod, limiting holes are equidistantly arranged corresponding to the fastening bolt. By setting the protection mechanism, loosen the fastening bolt, stretch the telescopic rod, and after the height is appropriate, tighten the fastening bolt. The fastening bolt is inserted into the limiting hole, and the height of the telescopic rod in the threaded pipe seat is limited, which is convenient for installers to adjust the height of the shielding plate, and then adjust the shielding area of the shielding plate for the solar water heater water tank, improving the service life of the solar water heater water tank. The application of this water tank effectively avoids the above problems and improves the practicability of the equipment.

[0004] However, for the above-mentioned solar water heater water tank with a purification device, although the water liquid is introduced into the purification tank through the water injection pipe, and the water liquid is introduced into the inner tank through the water inlet pipe under the purification effect of the activated carbon filter plate, there are still the following obvious defects during use: Since there is an activated carbon filter plate for filtering water, and there are more sediments and water scales in tap water and well water, because there is no pre-filtering component, it is easy for the activated carbon filter plate to be blocked by sediments or water scales after a short time of use, and then the service time and life of the activated carbon filter plate become shorter.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-3 , the present invention provides a technical solution: a water tank for a solar water heater with a filtering structure, including:

[0024] A water tank 1, on one side of the water tank 1, there is a water inlet filtering cylinder 2 for filtering the incoming water. The water inlet filtering cylinder 2 serves as the water inlet of the water tank and can also filter the incoming water in a timely manner, which can improve the quality of the used water. One end of the water inlet filtering cylinder 2 is threadedly penetrated with an activated carbon filter cylinder 3 for adsorbing and filtering the incoming water, which can adsorb and filter and purify the water preliminarily treated in the secondary water tank 5, and can enhance the water quality. One end of the activated carbon filter cylinder 3 is hermetically sleeved with a dismountable water inlet elbow head 4 for delivering water into the activated carbon filter cylinder 3, which can deliver the water in the secondary water tank 5 to the water tank 1 through the water inlet elbow head 4 for further adsorption and filtering. The secondary water tank 5 is arranged at the end of the water tank 1 and is communicated with the water inlet end of the water tank 1, so that the water in the secondary water tank 5 automatically flows into the water tank 1 through the water inlet elbow head 4 for use. And at the end of the secondary water tank 5, there is a square bar-shaped filter plate 6 for preliminarily filtering the water entering the interior of the secondary water tank 5, which can filter sediment and scale impurities in the incoming tap water or groundwater, and is conducive to replacing the square bar-shaped filter plate 6. The other end of the secondary water tank 5 is connected with a connecting water inlet fitting 7 for delivering water from an external water pipe into the secondary water tank 5, so that external water resources can enter the secondary water tank 5 through the water inlet fitting 7 and be preliminarily filtered by the square bar-shaped filter plate 6, thereby reducing the adsorption and filtration of water by the activated carbon filter cylinder 3.

[0025] One end of the water inlet filter cylinder 2 is fixedly penetrated on the outer side of the water tank 1, which is conducive to the function of filtering the water entering the interior of the water tank 1 and then entering. The other end of the water inlet filter cylinder 2 extends into the interior of the water tank 1 and is uniformly penetrated with water outlet mesh holes 8 on the surface, which is conducive to the water filtered by the activated carbon filter cylinder 3 entering the water tank 1 through the water outlet mesh holes 8 for use. One end of the activated carbon filter cylinder 3 is connected with a water inlet pipe head 9 with an external thread, which can be threadedly communicated with the water inlet elbow head 4 to allow water to enter the interior of the water tank 1. Moreover, the activated carbon filter cylinder 3 extends into the interior of the water inlet filter cylinder 2, enabling the entering water to be adsorbed and filtered in a timely manner. The interior of the activated carbon filter cylinder 3 is staggeredly provided with adsorption carbon plates 10 for adsorbing and filtering the entering water, which can adsorb and filter substances such as sediment or water impurities in the water, enhancing the quality of the water output from the water tank 1.

[0026] Both ends of the water inlet elbow head 4 are provided with screw connection pipe heads 11 with internal threads, which can enable the water inlet elbow head 4 to be screwed with the activated carbon filter cylinder 3 through the screw connection pipe heads 11 for the function of re-adsorbing and filtering water. Moreover, the screw connection pipe head 11 at one end of the water inlet elbow head 4 is hermetically screwed on the water inlet pipe head 9, which is conducive to the disassembly and replacement of the water inlet elbow head 4 and the activated carbon filter cylinder 3. One end of the secondary water tank 5 is provided with a water outlet pipe 12, which is convenient for conveying the filtered water to the water tank 1 through the water outlet pipe 12. The water outlet pipe 12 is threadedly communicated with the screw connection pipe head 11 at the other end of the water inlet elbow head 4, and the water inlet elbow head 4 and the secondary water tank 5 can be separated and removed. The top of the square strip-shaped filter plate 6 is provided with a disassembly and installation sealing cover plate 13 that is hermetically covered at the end of the secondary water tank 5 by screws. The disassembly and installation sealing cover plate 13 is fixed at the end of the secondary water tank 5 by screws, and a waterproof sealing rubber ring 14 is provided on the contact surface between the disassembly and installation sealing cover plate 13 and the exterior of the secondary water tank 5, enabling the disassembly and installation sealing cover plate 13 to be sealed by the waterproof sealing rubber ring 14 after being fixed by screws, preventing the water in the secondary water tank 5 from overflowing. One side of the water tank 1 is penetrated with a water outlet fitting 15, and a heat preservation cotton 16 is provided outside the inner tank of the water tank 1 for the function of heat-preserving the water inside the water tank 1.

[0027] Specifically, during use, first connect the water inlet pipe fitting 7 on the auxiliary water tank 5 to the water conveyance pipeline of external tap water or groundwater. Then, convey water through the water inlet pipe fitting 7 into the auxiliary water tank 5 and make it flow towards the other end of the auxiliary water tank 5. The flowing water passes through the square bar-shaped filter plate 6 installed inside the auxiliary water tank 5 for filtration. The square bar-shaped filter plate 6 can filter out sediment or scale impurities existing in the water. The square bar-shaped filter plate 6 can be removed from the auxiliary water tank 5 through disassembling and installing the sealing cover plate 13 for cleaning or replacement, which can reduce the purification and filtration pressure of the activated carbon filter cartridge 3, improve the quality of the water after filtration treatment, and at the same time reduce the occurrence of the phenomenon that the activated carbon filter cartridge 3 is blocked by sediment or scale and cannot perform filtration. Subsequently, the water filtered by the square bar-shaped filter plate 6 flows into the interior of the water inlet elbow 4 through the water outlet pipe 12. The middle part of the water inlet elbow 4 is transparent, enabling the observation of the water inflow volume in the water tank 1. The water entering the interior of the water inlet elbow 4 flows downward and enters the interior of the water inlet pipe head 9 through the screw joint pipe head 11. The water passes through the water inlet pipe head 9 and enters the interior of the activated carbon filter cartridge 3, enabling the activated carbon filter cartridge 3 to adsorb and filter out a small amount of impurities and harmful substances existing in the water. Due to the pre-treatment of water by the provided auxiliary water tank 5, the quality of the water filtered by the activated carbon filter cartridge 3 can be better. And due to the setting of the external thread water inlet pipe head 9 on the activated carbon filter cartridge 3, it is conducive to the later disassembly, replacement or cleaning of the activated carbon filter cartridge 3 during use, thereby improving the service life and cycle of the activated carbon filter cartridge 3.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
