[0016] The utility model makes further detailed description below combining with the drawings and specific embodiment.

[0017] Please see Figs. 1-2 As shown in the utility model discloses an intelligent self-adjusting environmental protection water tank, it includes box 11, heating pipe 12, motor 13, pivot 14, rotary blade 15, temperature sensor 16, controller 17.

[0018] The box 11 is formed with the cavity for containing water, the heating pipe 12 is connected to the side wall of the box 11, and the end of the heating pipe 12 is contained in the cavity, the heating pipe 12 is arranged at the lower part of the box 11, and the heating pipe 12 heats the water contained in the box 11. The bottom of the box 11 is provided with a support leg 18, and the bottom of the box 11 is provided with a drain port 19.

[0019] The temperature sensor 16 is connected to the side wall of the box 11, and the end of the temperature sensor 16 is contained in the cavity, the current temperature value of the water in the cavity is detected by the temperature sensor 16 and is transmitted to the controller 17.

[0020] The motor 13 is fixedly arranged at the top of the box 11, the output end of the motor 13 is located in the cavity, and the output end of the motor 13 is connected to the pivot 14, the pivot 14 is driven to rotate by the motor 13, and the pivot 14 is arranged along the vertical direction.

[0021] The rotary blade 15 is fixedly arranged on the pivot 14, the rotary blade 15 includes a first blade 151, a second blade 152 and a third blade 153, the first blade 151, the second blade 152 and the third blade 153 are arranged in the height direction of the pivot 14 from top to bottom, the maximum outer diameter size of the first blade 151 is equal to the maximum outer diameter size of the second blade 152, the maximum outer diameter size of the second blade 152 is greater than the maximum outer diameter size of the third blade 153, a plurality of through holes 1521 are arranged on the second blade 152, and the plurality of through holes 1521 are arranged on the second blade 152. In the height direction of the box 11, the third blade 153 is located above the temperature sensor 16, and the temperature sensor 16 is located above the heating pipe 12.

[0022] The first blade 151, the second blade 152 and the third blade 153 are arranged in the height direction of the pivot 14 from top to bottom, and their maximum outer diameter sizes are different, wherein the maximum outer diameter sizes of the first blade 151 and the second blade 152 are equal and greater than the maximum outer diameter size of the third blade 153. The difference in size can produce different degrees of water flow disturbance effect at different height layers.

[0023] When the motor 13 drives the rotating shaft 14 to rotate, the first blade 151 and the second blade 152 (larger outer diameter) located at the upper part will push the upper water body to generate a larger range of rotational motion, so that the upper water body forms a larger circulation, thereby driving the overall motion of the upper water body. At the same time, the third blade 153 (smaller outer diameter) will generate a relatively smaller range but more concentrated disturbance to the lower water body, so that the lower water body can also form a local water flow motion.

[0024] This layered water flow disturbance can break the laminar flow state of the water in the tank 11 and avoid the formation of water temperature stratification. During heating, since the heating pipe 12 is usually arranged at the lower part of the tank 11, it is easy to cause stratification phenomenon that the bottom water temperature is higher and the upper water temperature is lower. The water flow disturbance of the blades of different sizes to the water at different heights can promote the heat exchange between the upper and lower water bodies, so that the heat can be more uniformly transmitted in the entire water tank, improving the uniformity of overall heating.

[0025] The second blade 152 is provided with a plurality of through holes 1521, which can produce a unique water flow effect when the blade rotates. When the second blade 152 rotates, the water flowing through the through holes 1521 will generate additional turbulence and vortex, further enhancing the local water flow mixing effect.

[0026] This not only can strengthen the water flow mixing of the layer where the second blade 152 is located, but also can spread the influence of the turbulence and vortex to the surrounding water body, which is helpful for the diffusion and transmission of heat. For example, during heating, the heat generated by the heating pipe 12 will gather near the bottom, and the complex water flow state generated by the rotation of the second blade 152 can pull the hot water at the bottom upwards, and the turbulence and vortex generated by the through holes 1521 can make it fully mixed with the surrounding cooler water, accelerating the transmission speed of heat from the bottom to other areas.

[0027] Since the rotating blade 15 is connected by the rotating shaft 14 and driven to rotate by the motor 13, the rotational motions of different blades cooperate with each other to form a complex water flow circulation system. The through holes 1521 on the second blade 152 and the blades of different sizes jointly form a multi-level and multi-angle water flow path in the tank 11, so that the water can flow and mix in different directions.

[0028] This overall cooperation can make the water in the tank 11 form a three-dimensional circulation flow, ensuring that the water can achieve good flow and heat exchange in the horizontal and vertical directions, improving the contact frequency and contact area of the heat generated by the heating pipe 12 and the water body, thereby improving the heat transfer efficiency of the heating pipe 12, accelerating the overall heating speed of the water in the water tank, and enhancing the heating performance of the water tank.

[0029] The controller 17 is connected with the motor 13 and the temperature sensor 16, and the controller 17 is configured to drive the motor 13 to operate at a first rotating speed when the current temperature value is greater than or equal to the preset temperature value, and drive the motor 13 to operate at a second rotating speed when the current temperature value is less than the preset temperature value, the second rotating speed being greater than the first rotating speed.

[0030] The controller 17 obtains the current temperature value of the water in the tank 11 in real time through the temperature sensor 16, and compares the current temperature value with the preset temperature value. When the current temperature value is greater than or equal to the preset temperature value, the motor 13 is driven to operate at the first rotating speed; when the current temperature value is less than the preset temperature value, the motor 13 is driven to operate at the second rotating speed. This way of dynamically adjusting the rotating speed of the motor 13 according to the comparison between the actual temperature and the preset temperature can accurately maintain the water temperature in the water tank near the preset temperature, avoid excessively high or low water temperature, and meet the requirements of specific industrial production on water temperature accuracy.

[0031] When the water temperature is lower than the preset temperature, the controller 17 drives the motor 13 to operate at the second rotating speed, and the rotating speed of the impeller 15 is increased. The increase of the rotating speed of the impeller 15 enhances the stirring and mixing of the water in the tank 11, so that the hot water around the heating pipe 12 can be quickly exchanged with the cold water in other areas, reducing the water temperature stratification phenomenon and accelerating the overall water temperature rising speed, thereby improving the heating efficiency and shortening the time for heating the water to the preset temperature, which helps to improve the efficiency of industrial production.

[0032] When the water temperature reaches or exceeds the preset temperature, the motor 13 operates at a lower first rotating speed. In this case, although a certain water flow stirring and mixing is maintained to maintain uniform water temperature, the rotating speed of the motor 13 is reduced and the power consumption is reduced. Through this control strategy of using different rotating speeds of the motor 13 at different temperature stages, the energy waste caused by the motor 13 still operating at a high rotating speed when the water temperature approaches or reaches the preset temperature is avoided, the purpose of energy saving is achieved, the design concept of the environmentally friendly water tank is met, and the operating cost of industrial production is reduced.

[0033] When the water temperature is low, the impeller 15 operates at a higher second rotating speed, which can quickly spread the hot water near the heating pipe 12, avoid high water temperature around the heating pipe 12, prevent local overheating from causing scaling or damage to the heating pipe 12, prolong the service life of the heating pipe 12, reduce the maintenance cost and downtime caused by the failure of the heating pipe 12, ensure the stable operation of the heating system, and indirectly improve the heating performance and overall reliability of the water tank.

[0034] The controller 17 adjusts the rotating speed of the motor 13 in real time according to the temperature, so that the stirring intensity of the rotating blade 15 matches the water temperature state. When the water temperature is low, the stirring is strengthened to accelerate heat transfer and mixing; when the water temperature approaches the preset temperature, the stirring intensity is appropriately reduced to maintain the uniform water temperature. In this way, the water temperature at different positions in the water tank can be more uniform during the entire heating process, avoiding the situation of local water temperature being too high or too low, improving the heating quality of the water in the water tank, and meeting the requirements of some industrial production processes which have high requirements on water temperature uniformity.

[0035] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
