[0026] Example 1

[0027] like Figure 1-3As shown, this embodiment provides a waste heat recovery device for wastewater discharge, including a support plate 1, a support block 2 welded to the bottom of the support plate 1, a wastewater purification mechanism 3 fixedly installed on the top of the support plate 1, a waste heat recovery mechanism 4 provided on one side of the wastewater purification mechanism 3, the wastewater purification mechanism 3 including a purification box 31, the purification box 31 fixedly installed on the top surface of the support plate 1, a control panel 32 provided on the surface of the purification box 31, a water inlet 33 opened on one side of the top of the purification box 31, a snap-fit ​​groove 34 fixedly installed in the middle of the inner wall of the purification box 31, an activated carbon filter 35 snapped into the inside of the snap-fit ​​groove 34, a snap-fit ​​groove 36 provided on the right side of the snap-fit ​​groove 34, an ultraviolet sterilization tube 37 snapped into the inside of the snap-fit ​​groove 36, the snap-fit ​​groove 36 fixedly installed on the inner wall of the purification box 31, and locking buckles and handles provided at the top of both the activated carbon filter 35 and the ultraviolet sterilization tube 37. An activated carbon filter 35, in conjunction with an ultraviolet sterilization tube 37, sterilizes the wastewater inside the purification tank 31. A water level gauge 38 is installed on the top of the purification tank 31, and a delivery pipe 39 is fixedly connected to the output end on the side of the purification tank 31. The delivery pipe 39 passes through the surface of the water pump 310, and a cold water tank 311 is installed on one side of the water pump 310. The water level gauge 38 is used to check the water level of the wastewater in the purification tank 31. The water pump 310, in conjunction with the delivery pipe 39, delivers the purified wastewater. The cold water tank 311 contains cold water. By setting up an activated carbon filter 35 in conjunction with an ultraviolet sterilization tube 37, harmful substances in the wastewater are further removed, further improving the wastewater purification capacity, greatly reducing the pollution of the environment by wastewater, and reducing the damage to the human body. By setting up a water level gauge 38 in conjunction with a control panel 32, the water level in the purification tank 31 can be observed at any time, effectively avoiding excessive water pressure and obstruction of flow.

[0028] Example 2

[0029] like Figure 4 , Figure 5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the waste heat recovery mechanism 4 includes a recovery box 41, which is fixedly connected to the output end of the conveying pipe 39. A wastewater inlet 42 is provided on one side of the surface of the recovery box 41, and a cold water inlet 43 is provided on the other side. The recovery box 41 is used to collect wastewater and cold water. The wastewater inlet 42 is fixedly connected to the output end of the conveying pipe 39, and the cold water inlet 43 is fixedly connected to the output end of the cold water tank 311. The conveying pipe 39 transports wastewater to the recovery box 41 through the wastewater inlet 42, and the cold water tank 311 transports cold water to the recovery box 41 through the cold water inlet 43. 1. The inside of the recycling box 41 is provided with an installation groove 44, in which a heat exchanger 45 is movably installed. A handle 46 is welded to the top of the heat exchanger 45. The handle 46, in conjunction with the installation groove 44, allows the heat exchanger 45 to be removed from the recycling box 41. A wastewater outlet 47 is provided at the bottom right side of the recycling box 41. A clean water outlet 48 is provided on the other side of the wastewater outlet 47. The wastewater outlet 47 discharges the wastewater from the recycling box 41, and the clean water outlet 48 discharges the cooled water after heat exchange. By using the handle 46 in conjunction with the installation groove 44, the heat exchanger 45 can be removed from the recycling box 41 for replacement or maintenance, further ensuring the continuity of the heat exchange effect of the heat exchanger 45.

[0030] The working principle of this waste heat recovery device for wastewater discharge will be explained in detail below.

[0031] like Figure 1-5 As shown, wastewater is first fed into the purification tank 31 through the inlet 33. The water level information is then transmitted to the control panel 32 via the water level gauge 38 to check whether the water level pressure exceeds the standard. The wastewater then passes through the activated carbon filter 35 to adsorb harmful particles. The ultraviolet sterilization tube 37 is then turned on via the control panel to heat and sterilize the wastewater that has passed through the activated carbon filter 35. The wastewater is then fed into the recovery tank 41 through the water pump 310 and the delivery pipe 39 via the wastewater inlet 42. The cold water in the cold water tank 311 is fed into the recovery tank 41 through the cold water inlet 43. The heat exchanger 45 then exchanges heat between the cold water and the wastewater to recover and utilize the waste heat. The ambient temperature wastewater and hot water are then discharged from the wastewater outlet 47 and the clean water outlet 48, respectively. Finally, the heat exchanger 45 is removed from the installation slot 44 via the handle 46 to separate it from the recovery tank 41 for replacement or maintenance, further ensuring the continuity of the heat exchanger 45's heat exchange effect.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
