Description

Technical Field

[0001] The present invention relates to the technical field of water heaters, and particularly to a storage water heater with convenient scale treatment. Background Art

[0002] During the long-term use of the heater, due to water quality problems, scale is likely to accumulate in its inner tank. These scales not only affect the thermal efficiency of the equipment but may also cause equipment damage or shorten its service life. The traditional scale removal methods mainly include two types:

[0003] One is physical cleaning: that is, after disassembling the equipment, use a high-pressure water gun to directly flush the internal accumulated scale. Although this method can directly remove most visible scales, the operation is complex and time-consuming. Especially for some equipment with complex structures (such as those with a compact inner tank design and dense pipelines), the disassembly process is very cumbersome, and frequent disassembly and assembly may cause damage to the equipment, reducing its sealing performance and overall performance. The other is chemical cleaning: that is, inject a descaling agent into the inner tank to dissolve the scale. This method is applicable to large-capacity containers that cannot be easily disassembled or heaters with complex internal structures. However, for those cases where the scale on the inner tank surface is severe and stubborn, relying solely on the descaling agent may not be able to completely remove all scales, and sometimes mechanical means need to be combined for auxiliary cleaning. Summary of the Invention

[0004] In order to overcome the disadvantages mentioned in the above background art, the present invention provides a storage water heater with convenient scale treatment.

[0005] A storage water heater with convenient scale treatment includes a base, a water tank fixedly connected to the base, an inner tank fixedly connected inside the water tank, a pipeline fixedly connected to the water tank and penetrating into the inner tank, a flow guide frame fixedly connected inside the water tank, one side of the flow guide frame communicating with the inner tank, a water pump fixedly connected inside the water tank and communicating with the flow guide frame, a sewage spray head fixedly connected to the lower part of one side of the inner tank, at least one heating pipe fixedly connected inside the water tank and penetrating into the inner tank, a fixed spray pipe fixedly connected inside the inner tank, two rotating spray pipes rotatably connected inside the inner tank, the fixed spray pipe being located between the symmetrically distributed rotating spray pipes, the sewage spray head, the fixed spray pipe and the rotating spray pipes all communicating with the other side of the flow guide frame, a fan blade fixedly connected to the side of the rotating spray pipe away from the sewage spray head, the fixed spray pipe being provided with a plurality of flared nozzles symmetrically distributed along the fixed spray pipe, and a sewage discharge assembly for discharging dirt provided on one side of the water tank.

[0006] Further explanation, the diameter of the flared nozzle closer to the fan blade is larger than that of the other flared nozzles.

[0007] Further explanation, the rotating spray pipe is provided with a plurality of flushing nozzles, and the flushing nozzles are staggeredly distributed with the flared nozzles.

[0008] Further explanation: It further includes adjusting plates symmetrically distributed along the diversion frame. The adjusting plates are slidably connected to the diversion frame and the fixed nozzle. On one side of the rotating nozzle close to the adjusting plate, there is a rotating ring fixedly connected, which is used to push the adjusting plate to slide closer to the fixed nozzle when the flushing nozzle of the rotating nozzle rotates from bottom to top.

[0009] Further explanation: The rotating ring is provided with a guiding groove, and the rotating ring is slidably connected to the adjacent adjusting plate through the guiding groove.

[0010] Further explanation: It further includes a pressure relief pipe. One side of the pressure relief pipe is communicated with the rotating nozzle, and the other side is communicated with the sewage nozzle. A pressure valve is fixedly connected to the side of the pressure relief pipe close to the rotating nozzle, and the pressure valves correspond to the rotating nozzles one by one.

[0011] Further explanation: It further includes diversion blocks symmetrically distributed along the diversion frame. The diversion blocks are fixedly connected to the side of the diversion frame close to the fan blades.

[0012] Further explanation: It further includes filter meshes symmetrically distributed along the diversion frame. The filter meshes are fixedly connected to the inlet of the diversion frame, and the fan blades are in contact with the adjacent filter meshes.

[0013] Further explanation: The sewage component includes a sewage pipe fixedly connected to one side of the water tank. The inlet of the sewage pipe is communicated with the inner tank. A cylinder is fixedly connected to the side of the inner tank close to the sewage pipe, and a blocking frame is fixedly connected to the telescopic rod of the cylinder to block the inlet of the sewage pipe.

[0014] Further explanation: The sewage component further includes a liquid level sensor fixedly connected to the diversion frame. The liquid level sensor is electrically connected to the water pump through a controller.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. The present invention utilizes the impact force of the descaling solution to make the rotating nozzle spray the descaling solution in a rotating manner, so as to perform multi-directional flushing on the scale inside the entire inner tank. It combines the advantages of physical cleaning and chemical cleaning, eliminates the disadvantages of each cleaning method, improves the cleaning effect, and at the same time, through the mutual spraying and flushing of the fixed nozzle and the rotating nozzle, prevents scale from adhering to the fixed nozzle and the rotating nozzle, and can timely discharge the flushed scale.

[0017] 2. In order to overcome the problem of weakened flushing force caused by gravity, the present invention uses the rotating ring to push and pull two adjusting plates through the guiding groove to form an automatic control system, so that when the flushing nozzle of the rotating nozzle rotates from bottom to top, the spraying amount of the descaling solution is increased, and at the same time, the rotation speed of the rotating nozzle is slowed down, the flushing time is prolonged, and the flushing effect is enhanced.

[0018] 3. Through the above automatic regulation system, the present invention can automatically adjust the distribution of the descaling solution according to the flushing position, ensuring that each part can obtain an appropriate cleaning intensity, and further improving the cleaning efficiency and quality.

[0019] 4. The present invention is provided with a pressure valve and a pressure relief pipe to timely release the high pressure caused by blockage, protecting the rotating spray pipe from damage, extending the service life of the equipment. At the same time, the pressure relief pipe is connected to the sewage spray head, so that the descaling solution in the rotating spray pipe is finally discharged to the sewage spray head, increasing the impact force at the sewage spray head and improving the sewage discharge effect.

[0020] 5. By setting front and rear diversion blocks, the present invention enables the dirt flowing to the right in the inner tank to be more precisely introduced into the sewage discharge assembly, accelerating the discharge of dirt.

[0021] 6. By setting a filter screen, the present invention can prevent the scale impurities in the inner tank from entering the diversion frame, thereby preventing the scale impurities from entering the fixed spray pipe and the rotating spray pipe, and further preventing the respective flared nozzles and flushing nozzles from being blocked. At the same time, when the fan blades rotate, they can automatically scrape the impurities on the filter screen, keeping the filter screen clean, avoiding additional manual cleaning work, and ensuring the normal operation of the system.

[0022] 7. After the rotating spray pipe rotates and cleans for a period of time, the present invention controls the movement of the blocking frame through a cylinder to achieve rapid sewage discharge, reducing the time cost of shutdown maintenance. The liquid level sensor is used to monitor the liquid level height in the inner tank and control the operation of the water pump accordingly, realizing automatic management and improving the safety and convenience of operation.

Detailed implementation manners

[0037] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions herein are used to explain the present invention, but do not limit the present invention.

[0038] Embodiment 1: A water storage heater with convenient scale treatment, such as Figures 1 to 5As shown in the figure, it includes a base 101. A water tank 102 is fixedly connected to the top of the base 101. An inner tank 103 is fixedly connected inside the water tank 102. A pipeline is fixedly connected to the upper left side of the water tank 102. The pipeline penetrates into the inner tank 103. Scale remover and water are poured into the inner tank 103 through the pipeline. A flow guide frame 104 is fixedly connected to the lower part inside the water tank 102. The right side of the flow guide frame 104 is communicated with the inner tank 103. A water pump 105 is fixedly connected inside the water tank 102. The water pump 105 is communicated with the flow guide frame 104. A sewage spray head 106 is fixedly connected to the lower left side of the inner tank 103. At least one heating pipe 107 is fixedly connected inside the water tank 102. The heating pipe 107 penetrates into the inner tank 103. A fixed spray pipe 108 is fixedly connected inside the inner tank 103. Rotating spray pipes 109 symmetrically distributed before and after along the fixed spray pipe 108 are rotatably connected inside the inner tank 103. The fixed spray pipe 108 is located between the two rotating spray pipes 109 before and after. The sewage spray head 106, the fixed spray pipe 108 and the rotating spray pipes 109 are all communicated with the left side of the flow guide frame 104. A fan blade 110 is fixedly connected to the right side of the rotating spray pipe 109. The fixed spray pipe 108 is provided with six groups of flared nozzles 111 symmetrically distributed before and after along the fixed spray pipe 108. The rightmost flared nozzle 111 faces the adjacent fan blade 110. The caliber of the rightmost flared nozzle 111 is larger than that of the other flared nozzles 111. The rotating spray pipe 109 is provided with six flushing nozzles, and the flushing nozzles are distributed in a staggered manner with the flared nozzles 111.

[0039] When the heater stops heating, the inner tank 103 can be descaled. The specific descaling operation is as follows: First, pour the scale remover into the inner tank 103 through the pipeline, and then fill the inner tank 103 with water through the pipeline. The scale remover and water are mixed to obtain a descaling solution. Then, start the water pump 105. The water pump 105 pumps the descaling solution in the inner tank 103 to the sewage spray head 106, the fixed spray pipe 108 and the rotating spray pipes 109 through the flow guide frame 104. The descaling solution in the fixed spray pipe 108 flows to the two rightmost flared nozzles 111 with larger calibers before and after, and is respectively sprayed onto the fan blades 110 on the front and back sides. The impact force of the descaling solution causes the fan blades 110 to rotate. The fan blades 110 drive the rotating spray pipes 109 to rotate synchronously. The rotating spray pipes 109 drive the multiple flushing nozzles on them to rotate, so that the descaling solution in the rotating spray pipes 109 is sprayed out rotationally. At the same time, when the descaling solution in the fixed spray pipe 108 flows to the rightmost flared nozzle 111 with a larger caliber, it is also sprayed out through the multiple flared nozzles 111 on the front and back sides of it, and respectively flushes the rotating spray pipes 109 on the front and back sides. The descaling solution sprayed out through each flushing nozzle of the rotating spray pipe 109 can also flush the fixed spray pipe 108. In addition, the flushed dirt settles at the bottom of the inner tank 103 under the action of gravity. The descaling solution sprayed out through the sewage spray head 106 can wash the water scale deposited at the bottom of the inner tank 103 to the right into the sewage component and discharge it outside the heater.

[0040] In summary, the present invention utilizes the impact force of the descaling solution, enabling the rotating nozzle 109 to spray the descaling solution in a rotating manner, which can perform multi-directional flushing on the scale inside the entire inner tank 103. It combines the advantages of physical cleaning and chemical cleaning, eliminates the disadvantages of each cleaning method, improves the cleaning effect, and at the same time, the fixed nozzle 108 and the rotating nozzle 109 spray and wash each other to prevent scale from adhering to the fixed nozzle 108 and the rotating nozzle 109. Moreover, the sewage discharge assembly can timely discharge the flushed scale.

[0041] As Figure 6 and Figure 7 shown, it further includes adjusting plates 201 symmetrically distributed before and after along the flow guide frame 104. The adjusting plates 201 are slidably connected to the flow guide frame 104 and slidably connected to the fixed nozzle 108. A rotating ring 202 is fixedly connected to the left side of the rotating nozzle 109. A guiding groove is formed on the right side of the rotating ring 202, and the rotating ring 202 is slidably connected to the adjacent adjusting plate 201 through the guiding groove. When the flushing nozzle of the rotating nozzle 109 rotates from bottom to top, the rotating ring 202 pushes the adjusting plate 201 to slide closer to the fixed nozzle 108 through the guiding groove.

[0042] During the process of the flushing nozzle of the rotating nozzle 109 rotating from bottom to top, the descaling solution is not only pushed by the pressure provided by the water pump 105 but also decelerated by the action of gravity when flowing out, resulting in a weakened flushing force and thus a weakened flushing effect. To overcome the influence of gravity, when the flushing nozzle of the rotating nozzle 109 rotates from bottom to top, the amount of the descaling solution sprayed is increased, and at the same time, the rotating speed of the rotating nozzle 109 is slowed down, and the flushing time is extended to enhance the flushing effect. The specific operation is as follows:

[0043] When the rotating nozzle 109 rotates, it drives the rotating ring 202 to rotate synchronously. When the flushing nozzle of the rotating nozzle 109 rotates from bottom to top, the rotating ring 202 pushes the two adjusting plates 201 to approach each other through the guiding groove, reducing the distance between the two adjusting plates 201, thereby reducing the amount of the descaling solution entering the fixed nozzle 108 from the flow guide frame 104, resulting in an increase in the amount of the descaling solution entering the rotating nozzle 109 from the flow guide frame 104, enhancing the flushing force of the rotating nozzle 109, while weakening the flushing force of the fixed nozzle 108, reducing the rotating speed of the fan blade 110, and thus slowing down the rotating speed of the rotating nozzle 109 and extending the flushing time of the rotating nozzle 109. On the contrary, when the flushing nozzle of the rotating nozzle 109 rotates from top to bottom, the flushing force of the rotating nozzle 109 weakens, and the flushing time of the rotating nozzle 109 shortens.

[0044] As Figure 8 and Figure 9As shown, it further includes a pressure relief pipe 301. The right side of the pressure relief pipe 301 is communicated with the rotating nozzle 109, and the left side of the pressure relief pipe 301 is communicated with the sewage discharge nozzle 106. Two pressure valves 302 are fixedly connected to the upper part of the right side of the pressure relief pipe 301, and the two pressure valves 302 correspond to the two rotating nozzles 109 respectively.

[0045] Although the flushing nozzle of the rotating nozzle 109 can be flushed by the descaling solution ejected from the flared nozzle 111, there is still a possibility that the flushing nozzle is blocked after long-term use. When the internal hydraulic pressure of the rotating nozzle 109 increases due to the blockage of the flushing nozzle, the pressure valve 302 is pressed open, and the descaling solution in the rotating nozzle 109 enters the pressure relief pipe 301 through the pressure valve 302, which plays an effect of timely pressure relief and protection, improves the service life of the rotating nozzle 109, and avoids the rotating nozzle 109 being pressed and broken. In addition, by connecting the pressure relief pipe 301 to the sewage discharge nozzle 106, the descaling solution in the rotating nozzle 109 is finally discharged to the sewage discharge nozzle 106, increasing the impact force at the sewage discharge nozzle 106 and improving the sewage discharge effect.

[0046] As Figure 10 and Figure 11 shown, it further includes flow guiding blocks 401 symmetrically distributed before and after along the flow guiding frame 104. The flow guiding blocks 401 are fixedly connected to the right side of the flow guiding frame 104. By arranging the front and rear flow guiding blocks 401, the dirt flowing to the right in the inner tank 103 can be more accurately introduced into the sewage discharge assembly, accelerating the discharge of dirt. A filter screen 402 symmetrically distributed along the flow guiding frame 104 is fixedly connected to the inlet of the flow guiding frame 104. The fan blade 110 is in contact with the adjacent filter screen 402. By arranging the filter screen 402, scale impurities in the inner tank 103 can be prevented from entering the flow guiding frame 104, thereby preventing scale impurities from entering the fixed nozzle 108 and the rotating nozzle 109, and further preventing the respective flared nozzles 111 and flushing nozzles from being blocked. In addition, when the fan blade 110 rotates, it will timely scrape off the impurities on the filter screen 402, achieving the effect of automatically cleaning the filter screen 402.

[0047] As Figures 11 to 13As shown in the figure, the sewage discharge assembly includes a sewage discharge pipe 501, which is fixedly connected to the right side of the water tank 102. The inlet of the sewage discharge pipe 501 is communicated with the inner tank 103. A cylinder 502 is fixedly connected to the right side of the inner tank 103. The telescopic rod of the cylinder 502 is fixedly connected with a blocking frame 503, and the blocking frame 503 blocks the inlet of the sewage discharge pipe 501. After the rotating spray pipe 109 rotates and cleans for a period of time, then control the telescopic rod of the cylinder 502 to extend to the right, so that the blocking frame 503 moves to the right until it no longer blocks the inlet of the sewage discharge pipe 501. At this time, the scale accumulated on the right side of the inner tank 103 quickly drains into the sewage discharge pipe 501 and then is discharged outside the heater through the sewage discharge pipe 501. A liquid level sensor 504 is fixedly connected to the flow guide frame 104. The liquid level sensor 504 is electrically connected to the water pump 105 through a controller. During the process of the scale draining into the sewage discharge pipe 501, a small amount of descaling agent solution inside the inner tank 103 will be discharged together with the scale. As the liquid level of the descaling agent solution inside the inner tank 103 drops to the position of the liquid level sensor 504, the liquid level sensor 504 controls the water pump 105 to stop in time through the control module.

[0048] It should be understood that the above description is only for exemplary purposes and does not mean to limit the present invention. Those skilled in the art will understand that the variant forms of the present invention will be included within the scope of the claims herein.
