Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery technology, specifically an energy-saving and environmentally friendly waste heat recovery device for coffee roasting. Background Technology

[0002] With the booming development of the coffee industry, coffee roasting, as a crucial step in determining the quality and flavor of coffee, has seen its energy consumption become an increasingly important concern. In traditional coffee roasting processes, the large amounts of high-temperature exhaust gases generated by the roasting machine are usually directly released into the atmosphere. This not only results in a serious waste of energy but also keeps roasting costs high. At the same time, the emission of high-temperature exhaust gases also has a negative impact on the environment, exacerbating thermal pollution and greenhouse gas emissions.

[0003] With the deepening of energy conservation and environmental protection concepts and the urgent need for sustainable development, the coffee roasting industry urgently requires effective waste heat recovery technology. Existing waste heat recovery devices have many shortcomings in practical applications. Some devices have complex structures, high installation and maintenance costs, and low heat exchange efficiency, failing to fully recover waste heat. Other devices lack effective treatment of impurities in the exhaust gas, leading to pipe blockage and affecting the service life and performance of the heat exchange equipment. Furthermore, most devices do not perform proper heat equalization treatment on the recovered heat, resulting in poor heat utilization. Utility Model Content

[0025] This utility model provides the following technical solution:

[0026] Example 1

[0027] Please see Figure 1-4 This utility model provides a technical solution: an energy-saving and environmentally friendly waste heat recovery device for coffee roasting, including a base 1, a recovery mechanism 2 on the top of the base 1, and a heat equalization mechanism 3 on the top of the recovery mechanism 2;

[0028] The recycling mechanism 2 includes a first box 21, which is fixedly connected to the top of the base 1 near the left side. An air inlet pipe 22 is fixedly connected to the left side of the first box 21. A filter plate 23 is provided on the top of the first box 21. A rotating rod 24 is rotatably connected to the top of the first box 21. A rotating plate 25 is fixedly connected to the top of the rotating rod 24. A bolt 26 is provided on the top of the rotating plate 25 near the right side. An air outlet pipe 27 is fixedly connected to the right side of the first box 21. A circulation pipe 28 is fixedly connected to the other end of the air outlet pipe 27. A second box 29 is fixedly connected to the top of the base 1 near the right side. A water inlet pipe 211 is fixedly connected to the top of the second box 29 near the front. A drain pipe 212 is fixedly connected to the bottom front of the water inlet pipe 211. A valve 213 is fixedly connected to the surface of the drain pipe 212.

[0029] The top of the first housing 21 has a groove matching the filter plate 23, and the surface of the filter plate 23 is connected to the groove by sliding up and down. The other end of the air inlet pipe 22 is fixedly connected to the exhaust pipe of the coffee roaster.

[0030] The rotating rod 24 is located to the left of the filter plate 23. The top of the rotating plate 25 is provided with a threaded hole that matches the bolt 26 near the right side. The bolt 26 is threaded into the threaded hole, and the bottom end of the bolt 26 is in contact with the top of the filter plate 23 to fix the filter plate 23.

[0031] The second housing 29 has holes on its left and right sides that match the circulation pipe 28, and the circulation pipe 28 passes through and is fixedly connected to the holes, with the circulation pipe located inside the second housing 29.

[0032] Example 2

[0033] Please see Figure 5Furthermore, based on Example 1, a heat equalization mechanism 3 was obtained.

[0034] The heat equalization mechanism 3 includes a fixed frame 31, which is fixedly connected to the top of the second housing 29. A motor 32 is fixedly connected to the top of the fixed frame 31. A rotating shaft 33 is fixedly connected to the output end of the motor 32. A turbine fan 34 is fixedly connected to the bottom end of the rotating shaft 33. A first gear 35 is fixedly connected to the surface of the output shaft of the motor 32. A stirring shaft 36 is provided on the top of the second housing 29 near the right side. A second gear 37 is fixedly connected to the surface of the stirring shaft 36 near the top.

[0035] The top of the second housing 29 has a hole that matches the rotating shaft 33, and the rotating shaft 33 passes through and is rotatably connected to the hole. The turbine fan 34 is close to the bottom of the inner wall of the second housing 29.

[0036] The top of the second housing 29 has a hole near the right side that matches the stirring shaft 36, and the surface of the stirring shaft 36 is penetrated and rotatably connected to the hole. The stirring shaft 36 is located inside the second housing 29, and the first gear 35 meshes with the second gear 37.

[0037] In actual operation, when this device is in use, the high-temperature, hot exhaust gas generated by the coffee roaster enters the first chamber 21 through the air inlet pipe 22. The filter plate 23 at the top of the first chamber 21 intercepts and filters impurities in the exhaust gas to prevent impurities from entering the subsequent recycling process and affecting the performance of the equipment. The filter plate 23 can be firmly fixed in the groove at the top of the first chamber 21 by the bolt 26 to ensure the filtration effect. When the filter plate 23 needs to be replaced, the bolt 26 is rotated in the opposite direction to move the bolt 26 upward. Then, the rotating plate 25 and the rotating rod 24 are rotated to move the bolt 26 away from the top of the filter plate 23. Then, the filter plate 23 is pulled out from the first chamber 21, and the new filter plate 23 is slid into the first chamber 21. The rotating plate 25 and the rotating rod 24 are rotated in the opposite direction again to rotate the bolt 26 to the top of the filter plate 23. Then, the bolt 26 is rotated to make the bottom end of the bolt 26 press tightly against the top of the filter plate 23. The filtered hot exhaust gas flows out from the air outlet pipe 27 and enters the second chamber 29 through the circulation pipe 28. The circulation pipe 28 passes through the holes on both sides of the second chamber 29, transferring waste heat to the second chamber 29 for heat exchange. Cold water is injected into the second chamber 29 through the water inlet pipe 211. The hot waste gas flows in the circulation pipe 28, fully exchanging heat with the cold water in the second chamber 29, transferring its own heat to the cold water, raising the temperature of the cold water, and completing the waste heat recovery and utilization. The cooled waste gas can be discharged from the device. When hot water is needed, the valve 213 on the drain pipe 212 is opened, and hot water can flow out. The motor 32 on the top of the fixed frame 31 operates, and its output end drives the rotating shaft 33 to rotate, which in turn causes the turbine fan 34 at the bottom of the rotating shaft 33 to agitate the air near the bottom of the inner wall of the second chamber 29, accelerating the flow of the hot waste gas in the second chamber 29 and promoting more complete heat exchange. At the same time, the first gear 35 on the output shaft surface of the motor 32 rotates and meshes with the second gear 37 at the top of the stirring shaft 36, driving the stirring shaft 36 to rotate inside the second housing 29, stirring the water inside the housing, making the water temperature distribution more uniform, and further improving the heat exchange efficiency and hot water quality.
