[0018] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0019] like Figure 1-Figure 4 A boiler waste heat recovery device shown includes a recovery box 1, a water tank 2 is installed on the upper end of the recovery box 1, a through groove 16 is opened on the front surface of the recovery box 1, a filtering mechanism is installed inside the through groove 16, an exhaust port 7 is installed on the right side of the recovery box 1, and an exhaust control mechanism is installed inside the exhaust port 7.
[0020] like Figure 2 As shown, a water inlet 5 is installed at the upper end of the left surface of the water tank 2, a drain outlet 4 is installed at the lower end of the right surface of the water tank 2, and a plurality of equidistantly arranged water pipes 9 are fixedly installed at the lower end of the water tank 2. The water pipes 9 are heated after contacting with the hot air inside the recovery box 1.
[0021] Two symmetrical inspection doors 3 are rotatably installed on the front surface of the water tank 2, an air inlet 6 is installed on the left surface of the water tank 2, and an exhaust port 7 is installed on the right surface of the water tank 2. The exhaust port 7 is provided with an exhaust control mechanism to discharge or accumulate hot air inside the recovery box 1.
[0022] like Figure 3 As shown, the exhaust control mechanism includes a rotating motor 8 fixedly mounted on one side surface of the exhaust port 7, a rotating rod 10 is mounted on the output end of the rotating motor 8, the rotating rod 10 passes through the exhaust port 7 and a rotating plate 11 is mounted, and the rotating plate 11 fits against the inner wall of the exhaust port 7.
[0023] like Figure 4 As shown, the filtering mechanism includes a movable frame 17 slidably mounted inside a through slot 16 , a T-shaped rod 14 is fixedly mounted on the front surface of the recovery box 1 at the upper end of the through slot 16 , and a rotating block 15 is rotatably mounted on the lower end of the T-shaped rod 14 .
[0024] A filter plate 13 is installed at the upper end of the movable frame 17, and limit blocks 12 are provided at the upper and lower ends of the inner wall of the recovery box 1. The limit blocks 12 limit the filter plate 13 to prevent it from deflecting during sliding.
[0025] Working principle: The boiler will generate a large amount of heat loss during the combustion process. The staff will transport water from the water inlet 5 to the inside of the water tank 2. A number of equidistantly arranged water pipes 9 are installed at the lower end of the water tank 2. The water pipes 9 are set to a repeatedly bent structure to effectively increase the surface area and improve the heating effect of the hot air on the water inside the water pipes 9. Hot air enters the recovery box 1 from the air inlet 6. A through groove 16 is provided on the front surface of the recovery box 1. A movable frame 17 is slidably installed inside the through groove 16. A filter plate 13 is installed on the upper end of the movable frame 17 to filter the air entering the recovery box 1 to prevent large dirt in the air from accumulating inside the recovery box 1 and causing the heating effect to deteriorate. A limit block 12 is installed on the rear side of the upper and lower surfaces of the inner wall of the water tank 2. The limit block 12 limits the filter plate 13 and also plays a fixing effect. When better operation is required, the staff rotates the rotating block 15 installed at the lower end of the T-bar 14 to open the through groove 16 to facilitate the removal of the filter plate 13 for replacement and cleaning. After the hot air contacts the water pipe 9, the water therein is heated and then transported to the inside of the water tank 2. When the temperature rises to the specified temperature, the staff controls the drain port 4 to discharge the water inside the water tank 2. After long-term use, the two symmetrical inspection doors 3 rotatably installed on the front surface of the water tank 2 are opened to clean the inside of the recovery box 1 to avoid affecting the subsequent waste heat recovery effect. A rotating motor 8 is provided on one side of the exhaust port 7. A rotating rod 10 is fixedly installed on the output end of the rotating motor 8. The rotating rod 10 passes through the exhaust port 7 and is installed with a rotating plate 11. The exhaust port 7 is opened by controlling the rotating plate 11 through the rotating motor 8, so that the hot air accumulated inside the water tank 2 is discharged.
