Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please see Figures 1-4 The present invention provides the following technical solution: a waste heat recovery device for an electric heating steam generator, comprising a fixed base 1, a housing assembly 8 fixedly installed above the fixed base 1, an input heat exchange assembly 5 fixedly installed at the upper position of the housing assembly 8, an output heat exchange assembly 6 fixedly installed at the upper position of the housing assembly 8 and at the side of the input heat exchange assembly 5, a waste heat recovery device body 3 provided on one side of the fixed base 1, a connecting pipe assembly 4 fixedly installed on the top of the waste heat recovery device body 3 near the housing assembly 8, the housing assembly 8 and the connecting pipe assembly 4 being connected by an expansion and stirring device 2, and an auxiliary utilization device 7 fixedly installed at the edge of the side of the housing assembly 8 away from the connecting pipe assembly 4.

[0023] Specifically, the expansion mixing device 2 includes a screw 21, a movable sleeve 22, a threaded hole 23, a connecting column 24, a mixing assembly 25, and a movable box 27. The movable box 27 is fixedly installed on the side of the connecting pipe assembly 4 near the box assembly 8. The connecting column 24 is fixedly installed on the side of the box assembly 8 and below the movable box 27. The movable sleeve 22 is fixedly installed below the movable box 27 and outside the connecting column 24. The bottom of the movable sleeve 22 is threaded with a screw 21. The bottom of the connecting column 24 has multiple threaded holes 23. The mixing assembly 25 is installed near the center of the movable box 27.

[0024] By adopting the above technical solution, staff can expand the water capacity of the device by using the combination of structures such as the movable box 27 and the connecting column 24 when needed, thereby better meeting the work needs when there is sufficient waste heat.

[0025] Specifically, the expansion mixing device 2 also includes a sealing ring 26, which is fixedly installed on one side of the box assembly 8 near the edge and outside the movable box 27.

[0026] By adopting the above technical solution, the device can ensure the sealing between the housing assembly 8 and the movable housing 27 through the sealing ring 26, thereby preventing the appearance of gaps and thus preventing accidental leakage.

[0027] Specifically, the stirring assembly 25 includes a rotating shaft 251, a motor 252, and stirring blades 253. The motor 252 is fixedly installed on one side of the movable box 27 and below the connecting pipe assembly 4. The rotating shaft 251 is fixedly installed on one side of the output end of the motor 252 and inside the movable box 27. Multiple stirring blades 253 are fixedly installed on the outside of the output end of the rotating shaft 251 and inside the movable box 27.

[0028] By adopting the above technical solution, the staff can stir the water flow by coordinating the structure such as the motor 252 and the stirring blade 253 when needed, so that the water temperature in the moving box 27 and the box assembly 8 tends to be consistent, thus better meeting the needs of the work.

[0029] In this embodiment, when the electric heating steam generator needs to utilize waste heat, if there is sufficient waste heat, the operator can rotate the screw 21 on the movable sleeve 22 in the expansion stirring device 2 to disengage it from the threaded hole 23 on the connecting column 24. Then, the operator can pull the waste heat recovery device body 3, connecting pipe assembly 4, movable box 27, and movable sleeve 22 to move, thereby adjusting the overall capacity of the movable box 27 and the box assembly 8. Then, the operator can rotate the screw 21 in the opposite direction to connect it with the corresponding threaded hole 23. Afterward, the operator can send enough water into the box assembly 8 and the movable box 27, and discharge the waste heat from the electric heating steam generator. The gas carrying residual heat is fed into the input heat exchange component 5, and then discharged through the output heat exchange component 6. During this process, the water in the housing component 8 and the moving housing 27 exchanges heat with the gas carrying residual heat through the input heat exchange component 5 and the output heat exchange component 6, thereby increasing the water temperature and utilizing the residual heat. The operator can start the motor 252 in the stirring component 25, which drives the stirring blades 253 to rotate through the rotating shaft 251, thereby stirring the water flow and making the water temperature in the moving housing 27 and the housing component 8 tend to be the same. The fixed seat 1 plays a supporting role, and the sealing ring 26 plays a role in ensuring the seal.

[0030] Example 2

[0031] The difference between this embodiment and embodiment 1 is that the auxiliary utilization device 7 includes a fixed box 71, a heat-conducting copper rod 72 and a door panel 75. The fixed box 71 is fixedly installed on the side of the box assembly 8 away from the connecting pipe assembly 4 near the edge. Multiple heat-conducting copper rods 72 are fixedly installed on the side of the fixed box 71 close to the box assembly 8 near the edge. The door panel 75 is installed on the side of the fixed box 71 away from the box assembly 8 via a hinge.

[0032] By adopting the above technical solution, workers can heat solids when needed through the combination of structures such as the fixed box 71 and the heat-conducting copper rod 72, thereby better meeting the work needs in different situations.

[0033] Specifically, the auxiliary device 7 also includes a first insulation cotton 73 and a second insulation cotton 74. The side wall of the fixed box 71 is filled with the first insulation cotton 73, and the inside of the door panel 75 is filled with the second insulation cotton 74.

[0034] By adopting the above technical solution, the device can reduce heat loss in the fixed box 71 through the first insulation cotton 73 and the second insulation cotton 74, thereby better meeting the needs of waste heat utilization and ensuring normal operation.

[0035] In this embodiment, during operation, the heat inside the housing assembly 8 enters the fixed box 71 through the heat-conducting copper rods 72 in the auxiliary utilization device 7. When it is necessary to heat the solid, the operator can open the door panel 75, put the solid into the fixed box 71, and then close the door panel 75. The heat conducted by the heat-conducting copper rods 72 can heat the solid. The first insulation cotton 73 and the second insulation cotton 74 can reduce the heat loss inside the fixed box 71, thereby better meeting the needs of waste heat utilization.

[0036] The structure and principle of the fixed base 1, the waste heat recovery device body 3, the connecting pipe assembly 4 consisting of the generator inlet, the box outlet, and the connecting pipe, the input heat exchange assembly 5 consisting of the flue pipe, the input flue inlet, the input flue outlet, and the fins, the output heat exchange assembly 6 consisting of the flue pipe, the output flue inlet, the output flue outlet, and the fins, and the box assembly 8 consisting of the water tank, the smoke box, the box inlet, and the ash removal door have been disclosed in a steam generator waste heat recovery device disclosed in Chinese Patent Application No. 202021496148.6. Its working principle is that the gas with waste heat is discharged into the flue pipe through the input flue inlet and discharged to the flue through the input flue outlet. Inside the chamber, the gas in the smoke chamber is discharged into the smoke inlet and outlet pipes through the smoke outlet and then discharged through the smoke outlet. The continuous discharge of gas causes the smoke inlet and outlet pipes to heat up, which can exchange heat with the water discharged into the water tank through the water inlet of the chamber. The fins on the smoke inlet and outlet pipes can accelerate the heat exchange process. After the water is heated, it is discharged from the water outlet of the chamber into the waste heat recovery device for use. This can reduce the time for the steam generator to heat the water. By using the gas with waste heat to preheat the water, the water itself has a relatively high temperature, thereby achieving the effect of waste heat recovery. This reduces the energy consumption of the steam generator when heating the water, making it more energy-efficient and environmentally friendly, and worthy of widespread use.

[0037] The working principle and usage process of this utility model are as follows: When the electric heating steam generator needs to utilize waste heat, if the waste heat is sufficient, the operator can rotate the screw 21 on the movable sleeve 22 in the expansion stirring device 2 to disengage it from the threaded hole 23 on the connecting column 24. Then, the waste heat recovery device body 3, connecting pipe assembly 4, movable box 27, and movable sleeve 22 are moved to adjust the overall capacity of the movable box 27 and the box assembly 8. Then, the screw 21 is rotated in the opposite direction to connect it with the corresponding threaded hole 23. Afterward, the operator puts enough water into the box assembly 8 and the movable box 27, and sends the gas with waste heat discharged from the electric heating steam generator into the input heat exchange assembly 5. Then, the gas is discharged through the output heat exchange assembly 6. During this process, the water in the box assembly 8 and the movable box 27 and the gas with waste heat are exchanged through the input heat exchange assembly 5 and the output heat exchange assembly 6. Heat exchange component 6 exchanges heat to increase the water temperature, thereby utilizing waste heat. The operator can start the motor 252 in the stirring component 25, which drives the stirring blades 253 to rotate through the rotating shaft 251, thereby stirring the water flow and making the water temperature in the moving box 27 and the box assembly 8 more consistent. The fixed seat 1 provides support, and the sealing ring 26 ensures a seal. During operation, the heat in the box assembly 8 enters the fixed box 71 through the heat-conducting copper rods 72 in the auxiliary utilization device 7. When it is necessary to heat the solid, the operator can open the door 75, put the solid into the fixed box 71, and then close the door 75. The heat conducted by the heat-conducting copper rods 72 will heat the solid. The first insulation cotton 73 and the second insulation cotton 74 can reduce the heat loss in the fixed box 71, thereby better meeting the needs of waste heat utilization.
