[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1-6 As shown, a waste heat recycling device includes a boiler body 1, a fixing box 2 is installed on the upper part of the boiler body 1, a fixing plate 3 is installed on the upper part of the fixing box 2, a baffle 4 is fixedly connected to the inner wall of the fixing box 2, there are multiple baffles 4, and a sealing mechanism 5 is arranged inside the baffle 4. The number of the sealing mechanisms 5 is the same as that of the baffles 4, and the multiple sealing mechanisms 5 correspond one to one to the multiple baffles 4.

[0025] A telescopic mechanism 6 is provided on one side of the blocking mechanism 5, and the blocking mechanism 5 includes a blocking plate 501. The outer surface of the blocking plate 501 is slidably connected to the baffle 4, and the outer surface of the blocking plate 501 is also slidably connected to the fixed box 2. A first circular hole 502 is provided on the inner wall of the blocking plate 501, and a second circular hole 503 is provided on the inner wall of the baffle 4. Each blocking plate 501 is provided with a first circular hole 502, and the positions of the first circular holes 502 are staggered. The first circular holes 502 and the second circular holes 503 are the same size.

[0026] The telescopic mechanism 6 includes a telescopic rod 601, the end of which is fixed on the outer surface of the fixed box 2. The extended end of the telescopic rod 601 is fixedly connected to a connecting plate 602. One side of the connecting plate 602 is fixedly connected to the blocking plate 501. The connecting plate 602 connects multiple blocking plates 501 together and can drive the multiple blocking plates 501 to move.

[0027] A plurality of heat exchange plates 7 are fixedly connected to the outer surface of the fixed plate 3, and an air guide plate 8 is provided inside the heat exchange plate 7. The upper surface of the air guide plate 8 is fixedly connected to the fixed plate 3, and the lower end of the air guide plate 8 does not contact the heat exchange plate 7. The hot air flows in an S-shaped trajectory inside the plurality of heat exchange plates 7 through the air guide plate 8. An air outlet 9 is provided at the bottom of one of the heat exchange plates 7, and a ventilation hole is provided at the upper part of one end of the fixed plate 3 to facilitate the outflow of hot air after heat exchange.

[0028] The inner wall of the fixed plate 3 is fixedly connected to a long plate 10, and a water inlet pipe 11 is installed on one side of the fixed plate 3, and an electric valve is provided on the water inlet pipe 11. A water outlet pipe 12 is installed on one side of the fixed box 2, and the end of the water outlet pipe 12 away from the fixed box 2 is connected to the boiler body 1, and an electric valve is provided on the water outlet pipe 12. The electric valve cooperates with the telescopic rod 601. When necessary, the electric valve can be automatically opened and closed. The two electric valves and the telescopic rod 601 are controlled by an external controller and operate according to the set movement sequence and steps. An air outlet pipe 13 is provided on the side of the fixed plate 3 away from the water inlet pipe 11, and the end of the air outlet pipe 13 away from the fixed plate 3 is connected to the boiler body 1.

[0029] It should be noted that in actual use of the device, the hot air generated inside the boiler body 1 enters the interior of the fixed plate 3 through the outlet pipe 13, and then enters the interior of the heat exchange plate 7 closest to the outlet pipe 13, flows downward along the air guide plate 8 to the bottom of the heat exchange plate 7, and then flows to the other side of the heat exchange plate 7 and flows upward, thereby entering the interior of the next heat exchange plate 7, and so on. The hot air exchanges heat with the water inside the fixed box 2 through the heat exchange plate 7, thereby heating the water. In the process of the hot air flowing in multiple heat exchange plates 7, the heat is gradually lost, and finally the hot air flows out at the outlet 9 at the bottom of the heat exchange plate 7 farthest from the outlet pipe 13. The hot air enters the water to release the final heat, and is discharged from the ventilation holes on the fixed plate 3, thereby achieving the effect of sufficient heat exchange and preventing heat loss.

[0030] The baffle 4 divides the water inside the fixed box 2 into multiple areas. The temperature of the area closer to the air outlet pipe 13 is higher. The water temperature in each area decreases in sequence according to the distance from the air outlet pipe 13. At a certain time, the water in the area closest to the air outlet pipe 13 is injected into the interior of the boiler body 1 through the water outlet pipe 12, that is, the water heated to the hottest area is added to the boiler body 1 to make up for the loss caused by water evaporation. Then the telescopic rod 601 drives the connecting plate 602 to move away from the fixed box 2, and the connecting plate 602 drives the multiple blocking plates 501 to slide toward the outside of the baffle 4. The first circular hole 502 on the blocking plate 501 closest to the air outlet pipe 13 is first connected to the The corresponding second circular holes 503 overlap, causing part of the water in the area with the lower water temperature by one level to be diverted to the area closest to the outlet pipe 13. The sealing plate 501 continues to move toward the outside of the baffle 4, thereby sealing the area closest to the outlet pipe 13. Part of the water in the area with the lower water temperature by two levels then flows to the area with the lower water temperature by one level, and so on. The water flows one by one, and then the telescopic rod 601 drives the sealing plate 501 to reset, separating and sealing all areas. The water inlet pipe 11 injects cold water into the area farthest from the outlet pipe 13, replenishing the water in this area, thereby achieving the purpose of replacing the water for better heat exchange.
