The heat treatment box 4 is installed on one side of the top of the equipment platform 1, and the preheating box 6 is installed on the side of the top of the equipment platform 1 near the heat treatment box 4. A feeding box 7 is installed on one side of the preheating box 6. A flap 11 is installed near the bottom of the preheating box 6 via a rotating shaft 12. The flap 11 has ventilation holes inside. A gas guide pipe 8 is installed on the top of the heat treatment box 4, and the end of the gas guide pipe 8 is located at the preheating box. The bottom of the preheating box 6 is connected to the heat treatment furnace 10 via the bottom of the feeding box 7 through the feeding pipe 9. A control switch 2 is installed in the middle of the bottom of the feeding pipe 9. The top of the feeding box 7 is located inside the preheating box 6 and has a feeding port 16. A chain belt 18 is installed inside the feeding box 7. A feeding plate 17 is installed on the outer surface of the chain belt 18. A connecting seat B15 is installed on one side of the bottom of the flip plate 11. A connecting seat A13 is installed on one side of the bottom of the preheating box 6. The connecting seat A13 and the connecting seat B15 are connected by a cylinder 14. The cylinder 14 drives the flip plate 11 to flip.

[0025] The working principle of the waste heat recycling heat treatment furnace energy-saving device based on Embodiment 1 is as follows: After the present invention is installed, the product is placed on top of the flip plate 11 inside the preheating box 6. During use, the product is heat-treated by the heat treatment furnace 10, and the exhaust gas is transported to the preheating box 6 through the gas guide pipe 8. The exhaust gas preheats the product on top of the flip plate 11. After preheating, the exhaust gas is transported to the treatment box 4 through the gas conveying pipe 5. After the heat treatment furnace 10 has finished processing, the control switch 2 is turned on, and the cylinder 14 is started. The cylinder 14 drives the flip plate 11 to flip, transporting the product on top of the flip plate 11 to the feed port 16. Then, through the chain belt 18 and the feeding plate 17, the product is transported to the discharge pipe 9, and then transported to the heat treatment furnace 10 through the discharge pipe 9, thus facilitating subsequent heat treatment of the product. At this point, the working process of the equipment is completed.

[0026] Example 2

[0027] like Figure 1 and Figure 4 As shown, the energy-saving device for a waste heat recycling heat treatment furnace proposed in this utility model, compared with Embodiment 1, further includes: a support base 3 installed on the top of the equipment platform 1 near the preheating box 6; a processing box 4 installed on the top of the support base 3 via a rubber seat 25; a vibration motor 27 installed at the bottom of the processing box 4; an exhaust pipe 23 installed on one side of the processing box 4 near the top; an absorption chamber 24 installed inside the processing box 4 near its outer surface; and the top of the preheating box 6 connected to the inside of the absorption chamber 24 via a gas supply pipe 5 for absorption. Both the bottom and inner bottom of chamber 24 are equipped with partitions 19, which are staggered to guide the exhaust gas. Both sides of the bottom of treatment box 4 are equipped with discharge pipes 26, and a control valve 28 is installed in the middle of the discharge pipes 26.

An exhaust pump 21 is installed in the middle of the exhaust pipe 22 to reduce the internal pressure of treatment box 4, thereby facilitating the heating and evaporation of sewage through heat.

[0028] In this embodiment, wastewater is transported to the treatment tank 4 through the inlet pipe 20, and waste gas is transported to the absorption chamber 24 through the gas supply pipe 5. The heat from the waste gas heats up the wastewater inside the treatment tank 4. At the same time, the vacuum pump 21 is started, and the air and steam inside the treatment tank 4 are extracted through the vacuum pump 21 and the vacuum pipe 22 and transported to the collection tank for steam collection. This creates a negative pressure inside the treatment tank 4, which facilitates the evaporation of wastewater, thus enabling wastewater recycling. When it is necessary to clean the dust inside the absorption chamber 24, the vibration motor 27 is started, which drives the treatment tank 4 to vibrate. At the same time, the control valve 28 is opened to connect the discharge pipe 26 and discharge the dust inside the absorption chamber 24.
