Description

Technical Field

[0001] The utility model relates to an engine, in particular to an external combustion engine, belonging to a power device. Background Art

[0002] An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. For example, internal combustion engines usually convert chemical energy into mechanical energy. The engine is applicable to both power generation devices and the entire machine including the power device (such as gasoline engines and aircraft engines). At present, the engines that drive vehicles are generally gasoline engines or diesel engines, that is, reciprocating piston four-stroke engines. This type of internal combustion engine burns intermittently and works intermittently. After the work is completed, the exhaust work is performed. The efficient external combustion engine is mainly a gas turbine. The high-temperature and high-pressure gas in the gas turbine will pass through the impeller and drive the impeller shaft to rotate at high speed. They all belong to internal combustion engines. The internal combustion engine has a compact structure and high efficiency. In addition to the internal combustion engine, there is also an external combustion engine. The external combustion engine generally heats the circulating working fluid first and performs work through the circulating working fluid. The steam engine is a famous external combustion engine. The external combustion engine adds an intermediate link, and the mechanical system is huge. The temperature of the working medium of the internal combustion engine is very high, which makes its requirements for materials very high. In short, internal combustion engines and external combustion engines are both important industrial power sources and are breakthrough inventions in the history of human technological development.

[0029] In order to make the technical purpose, technical solution and beneficial effects of the utility model clearer, the technical solution of the utility model is further described below in conjunction with the drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model, that is, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The components of the embodiments of the utility model described and shown in the drawings can be arranged and designed in various different configurations.

[0030] The specific embodiment 1 of the engine involved in the utility model is Figure 1-Figure 7In the embodiment, both ends of the first cylindrical shell 1 of the exhaust gas motor are closed. In the specific manufacturing process, a cylindrical body is machined, and then upper end plates are arranged at both ends of the cylindrical body to form the first cylindrical shell. A first main shaft 2 is coaxially rotatably assembled in the first cylindrical shell 1. Both ends of the first main shaft 2 extend out of the first cylindrical shell 1, and the two are rotatably assembled through bearings 3. A first cam 4 is arranged on the first main shaft 2 to stop rotation. The first cam 4 rotates together with the first main shaft 2, and the first cam 4 is in the first cylindrical shell 1. Three first cam teeth 5 are evenly convexly arranged on the outer peripheral surface of the first cam 4. The first cam teeth 5 extend from one end of the first cylindrical shell 1 to the other end. Both ends and the outer edge of the first cam teeth 5 are slidably sealed with the first cylindrical shell 1, including sealing with the inner wall of the first cylindrical shell and the end plate of the first cylindrical shell. The first baffles 6 are evenly arranged on the circumference of the first cylindrical shell 1. There are three first baffles 6, which are the same as the number of the first cam teeth 5. The first baffles 6 are radially slidably arranged on the side wall of the first cylindrical shell 1, and there is a spring between the two, so that the first baffles 6 can be elastically pressed against the circumference of the first cam 4. The inner end of the first baffle 6 is an inclined surface, and the side of the first cam tooth 5 in front of the rotation direction is a curved surface. When the first cam 4 rotates, the side of the first cam tooth 5, which is a curved surface, pushes and cooperates with the inclined surface of the first baffle 6 to press the first baffle 6 outward, so that the first cam tooth 5 can pass over the first baffle 6. The so-called front and back in the rotation direction refers to the position of the first cam tooth in the movement process, the first position reached by the first cam tooth is the back, and the position reached by the last is the front. On the circumference of the first cylindrical shell 1, the first air inlet C2 and the first exhaust port B2 are respectively opened on both sides of each first baffle 6, wherein the first air inlet C2 is connected to the flue gas outlet C1 of the solid combustion furnace 9. After the high-temperature and high-pressure flue gas enters the first air inlet C2, pressure will be applied to the partition and a first cam tooth, and the first cam 4 will rotate. When the pressurized first cam tooth turns to the adjacent first exhaust port C3, the flue gas will be discharged. Then this first exhaust port is the first exhaust port for discharging hot gas. Under the action of inertia, the pressurized first cam tooth will cross the partition next to the first exhaust port for discharging hot gas. After further crossing the first air inlet next to the partition, the pressurized first cam tooth continues to rotate, and the space between it and the partition increases. Under the action of negative pressure, the first air inlet B1 will inhale air. When the pressurized first cam tooth continues to cross the first exhaust port in front of the next partition, the first exhaust port will discharge the cold air just inhaled. That exhaust port is the first exhaust port B2 for discharging cold air. For the same reason, the next air inlet is also an air inlet for inhaling cold air, and the next exhaust port is also the first exhaust port for discharging cold air. The cold air here is relative to the flue gas. Whether it is the incoming flue gas or the discharged flue gas, the temperature is relatively high. Conversely, heat is relative to cold air.

The combustion chamber 10 also has a fuel inlet and a combustion-supporting gas inlet B3. The two first exhaust ports B2 for discharging cold air are connected to the combustion-supporting gas inlet B3 of the solid combustion furnace 9. In order to prevent the hot gas in the combustion-supporting gas inlet from flowing back, a one-way valve is provided at the two first exhaust ports for discharging cold air. A sealing door is provided on the fuel inlet, and an ash discharge valve is also provided at the lower part of the solid combustion furnace 9.

The two ends and the outer edge of the second cam tooth 15 are slidably sealed with the second cylindrical shell 13. A second partition 16 is provided on the circumferential surface of the second cylindrical shell 13. The number of the second partition 16 is the same as that of the second cam teeth 15. The second partition 16 is radially slidably arranged on the side wall of the second cylindrical shell 13, and there is a spring between the two, which can make the second partition 16 elastically pressed against the circumferential surface of the second cam 7. The inner end of the second partition 16 is an inclined surface, and the side surface of the second cam tooth 15 in front of the rotation direction is a curved surface. When the second cam 7 rotates, the side surface of the second cam tooth 15 is pushed and matched with the inclined surface of the second partition 16 to press the second partition 16 outward, so that the second cam tooth 15 can pass over the second partition 16. A second air inlet D2 and a second air outlet D3 are respectively provided on the circumferential surface of the second cylindrical shell 13 at both sides of each second partition plate 16 , and the second air inlet D2 is connected to the water vapor outlet D1 .

The first exhaust port C3 for discharging hot gas is connected to the smoke channel 21 of the corresponding heat exchanger, and the second exhaust port D3 is connected to the inlet of the steam channel 22 of the corresponding heat exchanger. The outlet of the steam channel of the corresponding heat exchanger is connected to the liquid storage tank 23, and is connected to the inlet D8 of the liquid storage tank 28. The liquid outlet of the liquid storage tank 23 is connected to the cooling medium inlet of a heat exchanger through a water pump, the cooling medium outlet of this heat exchanger is connected to the cooling medium inlet of another heat exchanger, and the cooling medium outlet of another heat exchanger is connected to the water inlet A8 of the water jacket 11.

[0035] A water pump 24 is synchronously driven on the second main shaft of the steam motor through a coupling. The water pump is connected in series between the liquid storage tank and the cooling medium inlet of the heat exchanger.

In this case, the flue gas outlet of the solid combustion furnace is connected to the combustion-supporting gas inlet of the fluid burner 25, and the flue gas outlet C1' of the fluid burner is connected to the first air inlet.

[0037] Specific embodiment 3 of the engine, in Fig. 9 In combination Figure 1-7In this embodiment, there is an exhaust gas motor and a fluid burner, and the structures of the exhaust gas motor and the fluid burner are the same as those of the embodiment 1.
