Description

Technical Field

[0001] This utility model relates to the field of boilers, and in particular to an energy-saving boiler with heat recovery and utilization. Background Technology

[0002] A boiler is a device used to heat water or other liquids and convert them into steam, hot water, or heated oil. Boilers utilize the heat generated by burning fuel or other heat sources to provide thermal energy for various applications. Boilers are generally classified into different types such as fire-tube boilers, water-tube boilers, and electric boilers. Boilers serve multiple purposes, including heating, hot water supply, industrial production, and power generation, and are an indispensable piece of equipment in modern production and daily life.

[0003] However, traditional boilers are inefficient at heat recovery and utilization, and cannot effectively recover and utilize the waste heat in the exhaust gas. They are usually inefficient in terms of thermal efficiency, which leads to more energy waste. As a result, a large amount of fuel needs to be consumed to maintain the required heat output, thus increasing energy costs.

[0004] Therefore, those skilled in the art have provided an energy-saving boiler with heat recovery and utilization to solve the problems mentioned in the background art. Utility Model Content

Compared to most traditional boilers, this boiler is equipped with a recovery mechanism that guides heat from the flue pipe into the water tank through heat-conducting plates and rings, thereby heating the water in the tank. The temperature of the water in the tank continuously increases, thus heating the internal space of the insulation shell, improving the heating efficiency of the boiler module. Furthermore, the auger blades, driven by a servo motor, circulate the water in the tank, further enhancing the efficiency of water heating and the efficiency of heat transfer to the insulation shell, thereby further improving the boiler's heat recovery efficiency.

[0037] A boiler module 6 is fixedly connected to the center of the upper surface of the base 1. A flue pipe 7 is fixedly connected to the center of the upper surface of the boiler module 6. A recycling mechanism 8 is provided on the outer wall of the flue pipe 7. The recycling mechanism 8 includes a heat-conducting plate 801 and a water tank 803. A heat-conducting ring 802 is fixedly connected to the outer wall of the heat-conducting plate 801. Multiple partitions 806 are fixedly connected to the middle of the inner wall of the water tank 803. A through groove 807 is opened on one side of the upper surface of the partition 806. A first connecting pipe 808 is fixedly connected to the lower end of one side of the outer wall of the water tank 803. A second connecting pipe 809 is fixedly connected to the upper end of one side of the outer wall of the water tank 803. A circulation pipe 8010 is fixedly connected to the end of the first connecting pipe 808 and the second connecting pipe 809 away from the water tank 803. A servo motor 8011 is fixedly connected to the upper surface of the circulation pipe 8010. An auger blade 8012 is fixedly connected to the output end of the servo motor 8011.

[0038] Compared to most traditional boilers, this boiler is equipped with a heat recovery mechanism 8, which guides the heat in the flue pipe 7 into the water tank 803 through the heat conduction plate 801 and heat conduction ring 802, thereby heating the water in the water tank 803. The temperature of the water in the water tank 803 will continuously increase, thereby heating the internal space of the insulation shell 2, which improves the heating efficiency of the boiler module 6. In addition, the auger blades 8012, driven by the servo motor 8011, can circulate the water in the water tank 803, which improves the efficiency of water heating and the efficiency of water temperature conduction to the interior of the insulation shell 2, thereby further improving the boiler's heat recovery efficiency.

[0039] The pipe body 501 is fixedly connected to the upper surface of the exhaust pipe 7. The first placement shell 503 and the second placement shell 505 are hinged together, so that the smoke discharged from the exhaust pipe 7 can be intercepted and filtered by the filter plate 508. A first limiting fixing strip 504 is fixedly connected to the outer wall of one side of the first placement shell 503, and a second limiting fixing strip 506 is fixedly connected to the outer wall of one side of the second placement shell 505.

A movable ring 509 is fixedly connected to the middle of the upper surface of both the first placement shell 503 and the second placement shell 505, so that the user can move the ring 509 through the groove. The moving ring 509 moves the first placement shell 503 and the second placement shell 505. The heat conduction plate 801 is fixedly connected to the middle of the outer wall of the exhaust pipe 7, and the water tank 803 is fixedly connected to the outer wall of the exhaust pipe 7.

The upper part of the other end of the outer wall of the water tank 803 is fixedly connected to the water outlet pipe 804, and the lower part of the other end of the outer wall of the water tank 803 is fixedly connected to the water inlet pipe 805. This allows water to enter the water tank 803 through the water inlet pipe 805 and be discharged through the water outlet pipe 804 after being heated to a suitable temperature. The front end of the outer wall of the water tank 803 is fixedly connected to the temperature sensor 9, so that the user can understand the water temperature in the water tank 803.

[0040] Working principle: First, water is injected into the water tank 803 through the inlet pipe 805. When the boiler module 6 is started, the flue gas carrying heat enters the exhaust pipe 7 and is guided by the heat-conducting plate 801, thus effectively guiding the heat to the heat-conducting ring 802 and then into the water flow. At the same time, the servo motor 8011 starts, and the auger blades 8012 transport the water from the upper space of the water tank 803 to the lower space through the circulation pipe 8010. This allows the heat carried by the water flow to be introduced into the internal space of the insulation shell 2 by the circulation pipe 8010 and the outer wall of the water tank 803. When the water temperature reaches a suitable level, it will be guided to the required location through the outlet pipe 804, such as a heating system, a domestic hot water system, or an industrial high-temperature sterilization system. After a period of use, the user can replace the filter mechanism 5 by moving the ring 509 and then separate the limit fixing strip by rotating the bolt to clean and maintain the internal filter plate 508 for the next replacement, thereby reducing downtime.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
