A water scale resistant solar water heater

Abstract

This utility model discloses a scale-resistant solar water heater, including a support frame, a drive motor, and a cleaning assembly. Starting the drive motor rotates gear one, which in turn drives gear two to rotate synchronously. Gear two meshes with an annular toothed plate, and the position of the annular toothed plate is fixed, causing gear two to rotate along the circumference of the annular toothed plate while rotating itself. The rotation of gear two drives a rotating rod, which in turn drives a cleaning brush. The bristles of the cleaning brush make close contact with the inner wall of the water storage tank, allowing the cleaning brush to clean the scale on the inner wall of the water storage tank. Descaling agent is added to the storage tank through the inlet pipe. Starting the bidirectional water pump allows the descaling agent inside the storage tank to enter the interior of the water storage tank through transport pipes two and one. The descaling agent soaks the scale on the inner wall of the water storage tank, dissolving stubborn scale and making it easier for the cleaning brush to remove it.

Description

Technical Field

[0001] This utility model relates to the field of solar water heaters, and in particular to a solar water heater that prevents scale buildup. Background Technology

[0002] A solar water heater is a device that uses solar radiation energy to heat water. By absorbing the sun's light energy and converting it into heat energy, it provides domestic hot water for homes, commercial spaces, and other places. It is an energy-saving and environmentally friendly renewable energy utilization device. However, solar water heaters produce scale during use. Scale is mainly formed by the precipitation and crystallization of minerals such as calcium and magnesium in the water during the heating process. It adheres to the vacuum tubes of the collector, the water storage tank, and the inner walls of the pipes, reducing heat transfer efficiency and shortening the life of the equipment.

[0003] A solar water heater consists of a collector, a storage tank, a piping system, and auxiliary devices. The collector is responsible for absorbing solar energy, and the storage tank stores hot water. Heat transfer is achieved through natural or forced circulation. It can efficiently provide hot water when there is sufficient sunlight, and needs to rely on electric auxiliary heating or other methods to supplement it when there is insufficient sunlight.

[0004] After prolonged use, scale will accumulate on the inner wall of the storage tank of a solar water heater. This scale is difficult to remove and forms an insulation layer, reducing the tank's heat retention capacity. The remaining scale can also pollute the water and breed bacteria and microorganisms.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-6This utility model provides an embodiment of a scale-resistant solar water heater, including a support frame 101, a drive motor 105, and a cleaning assembly. A collector 102 is fixedly connected to the top of the support frame 101, and a water storage tank 103 is fixedly connected to the top of the support frame 101. The water storage tank 103 is fixedly connected to the collector 102. A cleaning assembly is installed inside the water storage tank 103. A mounting frame 104 is fixedly connected to one side of the water storage tank 103, and a drive motor 105 is fixedly connected to one side of the mounting frame 104. A gear 106 is rotatably connected to the output end of the drive motor 105. A gear 107 is rotatably connected to one side of the mounting frame 104, and the gear 107 meshes with the gear 106. An annular toothed plate 108 is fixedly connected inside the mounting frame 104, and the annular toothed plate 108 meshes with the gear 107. The upper part of the mounting frame 104... The square card has an annular groove 109. A rotating rod 110 is fixedly connected above the second gear 107. The transmission rod rotates inside the annular groove 109. A cleaning brush 111 is fixedly connected above the rotating rod 110. The drive motor 105 is started to drive the first gear 106 to rotate. The rotation of the first gear 106 drives the second gear 107 to rotate synchronously. The second gear 107 meshes with the annular toothed plate 108. The position of the annular toothed plate 108 is fixed, so that the second gear 107 will make a circular motion along the circumference of the annular toothed plate 108 while rotating itself. The rotation of the second gear 107 drives the rotating rod 110 to rotate. The rotation of the rotating rod 110 drives the cleaning brush 111 to rotate. The bristles of the cleaning brush 111 are in close contact with the inner wall of the water storage tank 103, so that the cleaning brush 111 can clean the scale on the inner wall of the water storage tank 103.

[0023] Please see Figures 2-5 In this embodiment, a transport pipe 201 is fixedly connected to one side of the water storage tank 103, a bidirectional water pump 202 is fixedly connected to one side of the transport pipe 201, a second transport pipe 203 is fixedly connected to one side of the bidirectional water pump 202, a liquid storage tank 204 is fixedly connected to one side of the second transport pipe 203, an outlet pipe 205 is fixedly connected to the other side of the liquid storage tank 204, and an inlet pipe 206 is fixedly connected to the top of the liquid storage tank 204. By placing the descaling agent into the liquid storage tank 204 through the inlet pipe 206, and by starting the bidirectional water pump 202, the liquid storage... The descaling agent inside the liquid tank 204 enters the water storage tank 103 through transport pipe 203 and transport pipe 1 201. The descaling agent soaks the scale on the inner wall of the water storage tank 103, thereby dissolving the stubborn scale and making it easier for the cleaning brush 111 to remove the scale. The wastewater after cleaning is transported from transport pipe 1 201 to transport pipe 203 through the bidirectional water pump 202, and then from transport pipe 203 to the liquid storage tank 204. The valve above the outlet pipe 205 is opened to discharge the wastewater through the outlet pipe 205.

[0024] Please see Figures 3-6 In this embodiment, a connecting pipe 301 is fixedly connected to the outside of the water storage tank 103. A water pump 302 is fixedly connected to one side of the connecting pipe 301. A connecting pipe 303 is fixedly connected to one side of the water pump 302. A filter box 304 is fixedly connected to one side of the connecting pipe 303. A sliding groove is provided inside the filter box 304. A filter plate 305 is slidably connected inside the sliding groove. A slot 306 is provided on one side of the filter plate 305. A locking block 307 is slidably connected inside the slot 306. A connecting plate 308 is fixedly connected to the outside of the filter box 304. A sliding rod 309 is fixedly connected to one side of the locking block 307. The sliding rod 309 passes through the connecting plate 308 to the outside of the connecting plate 308. One side of the filter box 304 is located on the sliding rod. A spring 310 is fixedly connected to the outer side of the filter box 309. One side of the spring 310 is fixedly connected to the connecting plate 308. The other side of the filter box 304 is fixedly connected to the liquid inlet 311. External water is transported to the filter box 304 through the liquid inlet 311. The water is filtered by the filter plate 305. The filtered water is then pumped into the water storage tank 103 through the connecting pipe 2 303 and the connecting pipe 1 301 by starting the water pump 302. By pulling the slide rod 309 outward, the slide rod 309 moves outward, causing the locking block 307 to move outward, so that the locking block 307 disengages from the locking groove 306, which squeezes the spring 310. This allows the filter plate 305 to be removed from the inside of the filter box 304 for easy cleaning.

[0025] During operation, external water is transported to the filter box 304 through the inlet 311. The water is filtered by the filter plate 305. The filtered water is then pumped into the water storage tank 103 by the start of the suction pump 302, through the connecting pipe 2 303 and the connecting pipe 1 301. By pulling the slide rod 309 outward, the slide rod 309 moves outward, causing the locking block 307 to move outward, disengaging the locking block 307 from the locking groove 306 and compressing the spring 310. This allows the filter plate 305 to be removed from the filter box 304 for cleaning. The start of the drive motor 105 drives the gear 106 to rotate, which in turn drives the gear 2 107 to rotate synchronously. The gear 2 107 meshes with the annular gear plate 108. The position of the annular gear plate 108 is fixed, so the gear 2 107 rotates along the circumference of the annular gear plate 108 while rotating itself. Gear 2 107 rotates, driving the rotating rod 110 to rotate. The rotating rod 110 then drives the cleaning brush 111 to rotate. The bristles of the cleaning brush 111 make close contact with the inner wall of the water storage tank 103, thus cleaning the scale on the inner wall of the water storage tank 103. The descaling agent is put into the liquid storage tank 204 through the water inlet pipe 206. The bidirectional water pump 202 is started to allow the descaling agent inside the liquid storage tank 204 to pass through the transport pipe 203 and the transport pipe. The first 201 enters the interior of the water storage tank 103, and the scale on the inner wall of the water storage tank 103 is soaked by the descaling agent, which can dissolve the stubborn scale and make it easier for the cleaning brush 111 to remove the scale. The cleaned wastewater is transported from the first transport pipe 201 to the second transport pipe 203 by the bidirectional water pump 202, and then from the second transport pipe 203 to the liquid storage tank 204. The valve above the outlet pipe 205 is opened to discharge the wastewater through the outlet pipe 205.

[0026] Through the above steps, the drive motor 105 is started to drive the gear 106 to rotate, and the rotation of the gear 106 drives the gear 2 107 to rotate synchronously. The gear 2 107 meshes with the annular toothed plate 108. The position of the annular toothed plate 108 is fixed, so that the gear 2 107 will make circular motion along the circumference of the annular toothed plate 108 while rotating itself. The rotation of the gear 2 107 drives the rotating rod 110 to rotate, and the rotation of the rotating rod 110 drives the cleaning brush 111 to rotate. The bristles of the cleaning brush 111 are in close contact with the inner wall of the water tank 103, so that the cleaning brush 111 can clean the scale on the inner wall of the water tank 103.
