Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Refer to Figure 1 and Figure 2, an embodiment provided by the present utility model: a boiler with waste heat conversion and utilization function, including an electric boiler 1, a heating cylinder 4 is arranged on the right side of the electric boiler 1, a waste water pipe 3 is connected to the left side of the heating cylinder 4, and the heating cylinder 4 is connected to the electric boiler 1 through the waste water pipe 3. A blast pipe 5 is fixedly connected inside the heating cylinder 4, and a plurality of air outlets 6 are connected to the top of the blast pipe 5. A waste gas pipe 7 is connected to the top right side of the electric boiler 1, and the bottom of the waste gas pipe 7 penetrates through the heating cylinder 4 and is connected to the blast pipe 5. A water tank 8 is fixedly connected to the top right side of the heating cylinder 4, and a stirring mechanism 2 is arranged inside the heating cylinder 4;

[0030] Specifically, after starting the electric boiler 1, the generated waste gas enters the blast pipe 5 through the waste gas pipe 7. At the same time, the waste water is transported to the heating cylinder 4 through the waste water pipe 3. When the waste water in the heating cylinder 4 reaches a certain amount, the blast pipe 5 discharges the waste gas through the air outlets 6. While the waste water adsorbs harmful substances such as dust in the waste gas, it is stirred to promote its flow. The temperature of the waste gas and waste water heats the clean water in the water tank 8. The waste gas can be filtered without an additional filtering structure, and at the same time, the heating effect on the clean water is improved, thereby enhancing the preheating conversion efficiency.

[0031] Refer to Figure 3 , the stirring mechanism 2 includes a rotating disk 202, the rotating disk 202 is rotatably connected to the inner top of the heating cylinder 4, a first paddle 201 is fixedly connected to the bottom of the rotating disk 202, dosing tanks 203 are connected to the front and rear sides of the left end of the top of the heating cylinder 4, a second paddle 205 is rotatably connected to the inner top of the water tank 8, and gears 204 are rotatably connected to the left and right sides of the inner bottom of the water tank 8. The bottom of the second paddle 205 is fixedly connected to the right gear 204, and the top of the first paddle 201 penetrates through the heating cylinder 4 and is fixedly connected to the left gear 204;

[0032] Specifically, the exhaust of the blast pipe 5 drives the waste water to stir in the heating cylinder 4, prompting the first paddle 201 and the rotating disk 202 thereon to rotate. The rotation of the first paddle 201 enhances the flow of the waste water in the heating cylinder 4, realizing uniform heating of the water tank 8. At the same time, when the rotating disk 202 turns to the bottom of the corresponding dosing tank 203, the cleaning agent or powder is sent into the heating cylinder 4 through the holes on the rotating disk 202, thereby purifying the waste water therein. The rotation of the second paddle 205 is driven by the meshing transmission of the two gears 204 to stir the water in the water tank 8 and enhance its heating effect by the heating cylinder 4.

[0033] Refer to Figure 1 and Figure 2, a controller 13 is fixedly connected to the front side of the water tank 8, and the controller 13 is electrically connected to the electric boiler 1; an outer shell 14 is fixedly connected to the outside of the controller 13, and a protective cover 15 is rotatably connected to the outside of the outer shell 14; positioning blocks 18 are fixedly connected to the outer periphery of the outer wall of the heating cylinder 4, and positioning holes 19 are formed in the outside of the plurality of positioning blocks 18;

[0034] Specifically, the start and operating power of the electric boiler 1 can be controlled through the controller 13, the protection ability of the controller 13 can be improved through the outer shell 14, the controller 13 can be prevented from being accidentally touched when not in use by opening and closing the protective cover 15, and the device can be easily installed and fixed by installing threaded parts in the positioning holes 19 on the positioning blocks 18.

[0035] Refer to Figure 1 and Figure 2 , fixing plates 16 are fixedly connected to the outer periphery of the outer wall of the electric boiler 1, and dampers 17 are fixedly connected to the bottoms of the plurality of fixing plates 16; a measuring cylinder 11 is communicated with the right side of the outer wall of the water tank 8, and an observation window 12 is formed in the front side of the measuring cylinder 11; a water inlet pipe 9 is communicated with the top of the water tank 8, and a drain pipe 10 is communicated with the right side of the heating cylinder 4;

[0036] Specifically, through the fixing plates 16 and the dampers 17 thereon, the vibration generated during the operation of the electric boiler 1 can be reduced, so as to improve its stability and reduce the generated noise. At the same time, the clear water in the water tank 8 will enter the measuring cylinder 11 through the connection relationship, so as to observe the current water level and whether it is boiling through the observation window 12. Water can be added to the water tank 8 through the water inlet pipe 9, and the sewage and waste gas in the heating cylinder 4 can be discharged through the drain pipe 10.

[0037] Working principle: Before using the device, first start the electric boiler 1. The exhaust gas generated then enters the explosion pipe 5 through the exhaust pipe 7, while the wastewater enters the heating cylinder 4 through the wastewater pipe 3. When the heating cylinder 4 is filled with wastewater, the explosion pipe 5 discharges the exhaust gas through the air outlet 6. At the same time, the wastewater adsorbs the harmful substances in the exhaust gas and stirs the wastewater to make it flow. The exhaust gas and wastewater heat the clear water in the clear water tank 8. Without installing an additional filtering structure, the exhaust gas can be filtered, and the heating effect of the clear water can be improved, so as to enhance the preheating conversion efficiency, thereby reducing the use cost of the device. And the exhaust of the explosion pipe 5 drives the wastewater to stir in the heating cylinder 4, driving the first paddle 201 and the rotating disk 202 thereon to rotate. The rotation of the first paddle 201 can enhance the flow of the wastewater in the heating cylinder 4 to uniformly heat the water in the clear water tank 8. The rotating disk 202 can bring the wastewater to the bottom of the corresponding dosing tank 203, which is connected to the heating cylinder 4. This enables the cleaning agent or powder to enter the heating cylinder 4 through the holes on the rotating disk 202 to purify the wastewater therein. At the same time, the second paddle 205 can be rotated through the meshing transmission of the two gears 204 to stir the water in the clear water tank 8 and enhance its heating effect by the heating cylinder 4. In this way, not only the heating efficiency is improved, but also the wastewater can be dosed quantitatively to purify the wastewater and the adsorbed exhaust gas, thereby improving the practicability of the device.

[0038] 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 recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
