[0004] This technical solution removes the waste residue by sliding left and right, but this treatment method will cause the fuel to splash everywhere during the combustion process. It is easy to cause the fuel to splash out of the steam engine during the charging process, and it will aggravate the dust phenomenon, resulting in an increase in the dust content of the exhaust gas discharged from the exhaust pipe, or it is easy for workers to inhale when opening the charging door to add fuel. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide a steam engine with waste heat recovery function to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a steam engine with waste heat recovery function, comprising a steam engine body, a motor installed on the outer surface of the steam engine body, and an eccentric wheel connected to the output end of the motor, a porous plate connected inside the steam engine body, and a guide seat connected to the top of the porous plate, a slide connected to the bottom of the porous plate, and a dredging rod connected inside the slide.

[0007] By adopting the above technical solution, the debris and dust generated after the combustion of the fuel enter the porous plate through the guide seat, and then the debris and dust pass through the porous plate and fall into the collection box. After the motor is started, the output end drives the eccentric wheel to rotate, and the eccentric wheel rotates to press against the dredging rod to make the dredging rod move up and down, so that the dredging rod dredges the porous plate to prevent the porous plate from being blocked and affecting the discharge of debris and dust. At the same time, the dredging rod is guided by the slide to prevent the dredging rod from being offset.

[0008] Furthermore, the top of the guide seat is sloped.

[0009] By adopting the above technical solution, the debris and dust generated after the fuel combustion enter the porous plate through the guide seat, and then the debris and dust pass through the porous plate and fall into the collection box.

[0010] Furthermore, the dredging rod is formed by welding a plurality of round rods, and the diameter of the top end of the dredging rod is smaller than the diameter of the holes on the porous plate.

[0011] By adopting the above technical solution, the diameter of the dredging rod is smaller than the diameter of the holes on the porous plate, which can prevent the dredging rod from blocking the porous plate and facilitate the dredging rod to dredge the holes on the porous plate.

[0012] Furthermore, the dredging rod is slidably connected to the slide.

[0013] By adopting the above technical solution, the dredging rod is guided by the slide during the up and down reciprocating motion of the dredging rod, thereby preventing the dredging rod from deflecting.

[0014] Furthermore, the dredging rod is slidably connected to the eccentric wheel.

[0015] By adopting the above technical solution, the eccentric wheel rotates to press against the dredging rod, causing the dredging rod to reciprocate up and down, thereby making the dredging rod dredge the porous plate.

[0016] Furthermore, a furnace body is connected to the upper part of the steam engine main body, and a steam outlet is connected to the top of the furnace body, a water inlet pipe is connected to the upper part of one side of the furnace body, a smoke exhaust pipe is connected to the upper part of one side of the steam engine main body, a feeding door is hinged on one side of the steam engine main body, and a collection box is passed through the lower part of one side of the steam engine main body.

[0017] By adopting the above technical solution, the staff opens the charging door and then spreads the fuel on the top of the guide seat. The staff then ignites the fuel. After the fuel is ignited, the temperature inside the steam engine body rises, thereby heating the furnace body. At the same time, water enters the furnace body through the water inlet pipe, causing the water to be heated and evaporated in the furnace body to produce steam. The steam is then discharged from the steam outlet into subsequent processing equipment, and the high-temperature exhaust gas generated by the fuel is discharged from the exhaust pipe.

[0018] Furthermore, the furnace body is located above the porous plate.

[0019] By adopting the above technical solution, the staff opens the charging door and then spreads the fuel on the top of the guide seat. The staff then ignites the fuel. After the fuel is ignited, the temperature inside the steam engine body rises, thereby heating the furnace body.

[0020] Furthermore, the collecting box is detachably connected to the steam engine body, and the collecting box is located below the porous plate.

[0021] By adopting the above technical solution, the debris and dust generated after the fuel combustion enter the porous plate through the guide seat, and then the debris and dust pass through the porous plate and fall into the collection box. Subsequent staff only need to take out the collection box and dump the residue and dust.

[0022] Furthermore, a heat exchanger is installed between the water inlet pipe and the smoke exhaust pipe.

[0023] By adopting the above technical solution, water enters the furnace body from left to right through the heat exchanger, and the exhaust gas is discharged from right to left through the heat exchanger, so that the high-temperature exhaust gas and water form a convection heat exchange, thereby preheating the water through the waste heat of the high-temperature exhaust gas, reducing the waste of heat energy.

[0024] In summary, the present invention has the following beneficial effects:

[0025] The utility model is provided with a porous plate, a guide seat, a motor, an eccentric wheel, a slide and a dredging rod. The debris and dust generated after the fuel is burned enter the porous plate through the guide seat, and then the debris and dust pass through the porous plate and fall into the collection box. After the motor is started, the output end drives the eccentric wheel to rotate, and the eccentric wheel rotates to press against the dredging rod to make the dredging rod move up and down, thereby making the dredging rod dredge the porous plate to avoid clogging of the porous plate and affecting the discharge of debris and dust. At the same time, the dredging rod is guided by the slide to avoid deviation of the dredging rod. It is convenient to guide the discharge of dust and debris, and there is no need to shake or bump to avoid splashing of fuel, residue and dust, and the dredging is automatic to avoid blockage.

[0033] The following describes an embodiment of the present invention based on its overall structure.

The dredging rod 14 is slidably connected to the eccentric wheel 12, and the eccentric wheel 12 rotates to press against the dredging rod 14 to make the dredging rod 14 reciprocate up and down, so that the dredging rod 14 dredges the porous plate 9 to prevent the porous plate 9 from being blocked and affecting the discharge of debris and dust.

[0036] See Figure 1-Figure 3In the above embodiment, a furnace body 6 is connected to the upper part of the steam engine main body 1. The furnace body 6 is located above the porous plate 9. A steam outlet 5 is connected to the top of the furnace body 6. A water inlet pipe 3 is connected to the upper part of one side of the furnace body 6. A smoke exhaust pipe 4 is connected to the upper part of one side of the steam engine main body 1. Water passes through the heat exchanger 2 and the water inlet pipe 3 and enters the furnace body 6, so that the water is heated and evaporated in the furnace body 6 to generate steam. The steam is then discharged from the steam outlet 5 and enters the subsequent processing equipment, and the high-temperature exhaust gas generated by the fuel enters the heat exchanger 2 from the smoke exhaust pipe 4 and is then discharged from the heat exchanger 2; one side of the steam engine main body 1 is hinged. There is a charging door 7. The staff opens the charging door 7 and then spreads the fuel on the top of the guide seat 10. Then the staff ignites the fuel.

[0037] Example 2:

[0038] On the basis of the above embodiment 1, in order to facilitate the recovery of waste heat and reduce heat energy waste, the following settings are now adopted.

[0039] See Figure 1 and Figure 2 In the above embodiment, a heat exchanger 2 is installed between the water inlet pipe 3 and the smoke exhaust pipe 4. Water enters the furnace body 6 through the heat exchanger 2 from left to right, and the exhaust gas is discharged from the heat exchanger 2 from right to left, so that the high-temperature exhaust gas and water form a convection heat exchange, thereby preheating the water through the waste heat of the high-temperature exhaust gas, reducing the waste of heat energy.

[0040] The working principle of the present invention is as follows: first, the worker opens the charging door 7 and then places the fuel on the top of the guide seat 10. Then, the worker ignites the fuel. After the fuel is ignited, the temperature inside the steam engine body 1 rises, thereby heating the furnace body 6. At the same time, water passes through the heat exchanger 2 and the water inlet pipe 3 and enters the furnace body 6, causing the water to be heated and evaporated in the furnace body 6 to generate steam. The steam is then discharged from the steam outlet 5 and enters the subsequent processing equipment. The high-temperature exhaust gas generated by the fuel enters the heat exchanger 2 through the exhaust pipe 4 and is then discharged from the heat exchanger 2.

[0041] Water enters the furnace body 6 from left to right through the heat exchanger 2, while the exhaust gas is discharged from the heat exchanger 2 from right to left, so that the high-temperature exhaust gas and water form a convection heat exchange, thereby preheating the water through the waste heat of the high-temperature exhaust gas, reducing the waste of heat energy;

[0042] The debris and dust generated after the combustion of the fuel enter the porous plate 9 through the guide seat 10, and then the debris and dust pass through the porous plate 9 and fall into the collection box 8. After the motor 11 is started, the output end drives the eccentric wheel 12 to rotate, and the eccentric wheel 12 rotates to press against the dredging rod 14, causing the dredging rod 14 to reciprocate up and down, thereby causing the dredging rod 14 to dredge the porous plate 9 to prevent the porous plate 9 from being blocked and affecting the discharge of debris and dust. At the same time, the dredging rod 14 is guided by the slide 13 to prevent the dredging rod 14 from deviating. Subsequent staff only need to take out the collection box 8 to dump the residue and dust.
