Technical Field

[0001] This utility model relates to the field of heat storage equipment technology, specifically to an electrically heated solid heat storage device. Background Technology

[0002] There are various types of electrically heated solid thermal storage equipment, including solid thermal storage electric boilers. A solid thermal storage electric boiler is a device that uses inexpensive electricity during off-peak hours at night to convert electrical energy into heat energy and store it, releasing the heat when needed. It primarily stores heat by electrically heating a solid medium (such as magnesia bricks or high-alumina bricks), and then releases the heat through a heat exchanger when heating is required for heating or heat supply.

[0003] However, existing solid-state thermal storage electric boilers have the following problems during use: After heating water, these boilers produce scale such as calcium carbonate and magnesium carbonate. Scale accumulation reduces the diameter of hot water pipes, affecting the flow rate and potentially causing blockages. Furthermore, it makes cleaning the inner parts of the hot water pipes difficult. Therefore, a corresponding technical solution is needed to address these problems. Utility Model Content

[0004] The purpose of this utility model is to provide an electrically heated solid thermal storage device, which solves the technical problem that solid thermal storage electric boilers produce scale such as calcium carbonate and magnesium carbonate after heating water. Scale accumulation will reduce the diameter of hot water pipes, affect the flow of hot water, and in severe cases may cause blockage of hot water pipes, making it difficult for workers to clean the inner part of the hot water pipes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electrically heated solid thermal storage device, comprising a solid thermal storage electric boiler and a hot water pipe installed on the solid thermal storage electric boiler.

[0018] Please see Figure 1-3This utility model provides a technical solution: an electrically heated solid thermal storage device, including a solid thermal storage electric boiler 1 and a hot water pipe installed on the solid thermal storage electric boiler 1. The hot water pipe includes a hot water guide straight pipe 2, a drain outer pipe 3, and a diversion pipe 4. The outer end of the hot water guide straight pipe 2 is connected to the vertically arranged drain outer pipe 3. The diversion pipe 4 is horizontally installed at the outer end of the hot water guide straight pipe 2. The diversion pipe 4 has an inlet 5, and a sealing plate 6 is longitudinally inserted in the inlet 5. An installation plate 7 is fixed at the outer end of the diversion pipe 4. A pull-out cleaning component is movably inserted in the installation plate 7. The pull-out cleaning component includes a hollow water guide pipe 8 and a flushing cleaner 9 fixed at the inner end of the hollow water guide pipe 8. A connector 10 is installed at the outer end of the hollow water guide pipe 8. The connector 10 is equipped with a valve 11 and an outer... The end of the hose 12 is connected to the outer end of the hose 12, and the outer end of the hose 12 is connected to the booster water pump 13. A handle 14 is fixed below the outer end of the hollow water guide pipe 8. The rinsing cleaner 9 includes a cover 15, a cap 16, a cleaning brush 17, a branch pipe 18, a nozzle 19, and a visualization component 20. The inside of the cover 15 forms an inner cavity 21. The inner end of the hollow water guide pipe 8 is located in the inner cavity 21. The cap 16 is threaded onto the end of the cover 15. The cleaning brush 17 is distributed around the cap 16. The branch pipe 18 is divided into several groups and evenly installed on the hollow water guide pipe 8. The outer ends of the several groups of branch pipes 18 are connected to several groups of nozzles 19. Several groups of slots 22 are evenly opened on the surface of the cover 15. Several groups of nozzles 19 are evenly distributed in several groups of slots 22. The visualization component 20 is installed at the tail of the cover 15.

[0019] Further improvements, such as Figure 2 As shown, the sealing disc 6 includes a disc body 23 and a lifting ring 24 fixed on the disc body 23. The diameter of the disc body 23 is equal to the inner diameter of the diversion pipe 4. Under normal water supply conditions, the sealing disc 6 seals the diversion pipe 4. When it is necessary to clean the water branch pipe 2, the sealing disc 6 is opened.

[0020] Further improvements, such as Figure 2 As shown, the inner diameter of the cover 15 is larger than the outer diameter, and the inner diameter of the cover 15 is smaller than the inner diameter of the hot water guide straight pipe 2. This design makes it easy to insert the flushing cleaner 9 into the hot water pipe.

[0021] Further improvements, such as Figure 3 As shown, the cleaning brush 17 is composed of several sets of PP plastic filaments, which are evenly distributed in a ring around the periphery of the cover 16. The cleaning brush 17 can clean the inner wall of the pipe after rinsing, thus improving the cleaning effect.

[0022] Specifically, the visualization component 20 includes a transparent cover 25, a camera 26, a lighting lamp 27, and a display screen 28. The transparent cover 25 is installed at the rear of the cover 15. The camera 26 and the lighting lamp 27 are both built into the transparent cover 15 and are connected to a waterproof cable 29. The camera 26 is connected to the display screen 28 through a line. The display screen 28 is installed at the outer end of the hollow water pipe 8. The lighting lamp 27 provides supplementary lighting and, together with the camera 26, allows observation of the scale adhering inside the hot water pipe and displays the observation on the display screen 28. Staff can intuitively observe the cleanliness of the inside of the pipe through the display screen 28.

[0023] In use: When scale appears on the inner wall of the hot water diversion straight pipe 2, the operator keeps the hot water diversion straight pipe 2 in a non-flowing state or stops the equipment. Then, the operator holds the handle 14 and inserts the pull-out cleaning component into the hot water diversion straight pipe 2, positioning the flushing cleaner 9 at the innermost part of the hot water diversion straight pipe 2. Supplemental lighting is provided by the lamp 27, and the operator observes the scale buildup inside the hot water pipe using the camera 26, displaying the observations on the display screen 28. The operator can visually observe the inside of the pipe through the display screen 28. The cleaning process is as follows: the hose 12 is connected to the connector 10, and the water is pressurized by the booster pump 13 and introduced into the branch pipe 18 and then into the nozzle 19 through the hollow water guide pipe 8. The nozzle 19 rinses the scale on the inner wall of the pipe. While rinsing, the staff slowly pulls the hollow water guide pipe 8 outward. During the outward pulling process, the cleaning brush 17 can be used to clean the inner wall of the pipe after rinsing, thereby improving the cleaning effect. The inner wall of the pipe is rinsed and cleaned repeatedly in the above manner to achieve the purpose of cleaning the hot water pipe.
