Utility Model Content

[0005] The purpose of this utility model is to provide a waste heat recovery device for lead alloy smelting flue gas in waste battery recycling, so as to solve the problems mentioned in the background art, such as the inconvenience of dual-channel flexible switching of flue gas transportation to recover waste heat, the difficulty of quickly disassembling and replacing filter plates and rotating and scraping the scale on the inner wall of the storage tank, which affects the convenience of scale cleaning.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waste heat recovery device for lead alloy smelting flue gas in waste battery recycling, comprising a storage tank and a valve body. The valve body is provided on the outside of the storage tank. A hydraulic cylinder is movably mounted on the top of the valve body. A push arm is mounted on the output end of the hydraulic cylinder. A connecting arm is provided at the end of the push arm away from the hydraulic cylinder.

[0013] Preferably, limit strips are symmetrically arranged on the side walls of the filter plate, and the limit strips are slidably connected to the limit grooves.

[0014] Compared with the prior art, the beneficial effects of this utility model are: this waste heat recovery device not only realizes flexible switching between dual channels to transport flue gas and recover waste heat, but also facilitates quick disassembly and replacement of filter plates and rotary scraping and cleaning of scale on the inner wall of the storage tank, avoiding equipment downtime due to damage to the serpentine copper pipe, but also improves the convenience of scale cleaning.

[0015] (1) Water is injected into the storage tank through the filling port, and the water level is above the serpentine copper tube. The flue gas containing residual heat is input into the valve body. The flue gas is transported through a set of channels in the valve body and then through the diversion pipe to a set of serpentine copper tubes. The residual heat is conducted to the water through the serpentine copper tubes and heats the water to generate steam. The steam is transported to the turbofan generator through the exhaust port to drive the blades to rotate and generate electricity, thereby realizing the recovery and utilization of the residual heat of the flue gas. If a set of serpentine copper tubes is damaged, in order to avoid equipment shutdown, the hydraulic cylinder drives the push arm to move, the push arm drives the connecting arm to rotate through the linkage shaft, the connecting arm drives the movable shaft to rotate, the movable shaft drives the valve plate to rotate, and the valve plate moves the damaged serpentine copper tube to the corresponding position. With one channel blocked, the flue gas is transported through another channel to another set of serpentine copper pipes to ensure normal recovery of flue gas waste heat. The flue gas is continuously transported through the serpentine copper pipes to the inside of the filter box, where the filter plate filters the dust particles in the flue gas. The filtered gas is discharged through the outlet pipe. When the filter plate needs to be replaced, pull the filter plate upwards. With the sliding cooperation of the limit strip and the limit groove, the filter plate can be removed from the inside of the filter box. Then, a new filter plate can be installed back into the limit groove. This realizes flexible switching between dual channels to transport flue gas and recover flue gas waste heat, which facilitates quick disassembly and replacement of filter plates and avoids equipment downtime due to damage to the serpentine copper pipes.

[0016] (2) After the water inside the storage tank is heated, scale will be generated and condensed on the inner wall of the storage tank. The stepper motor drives the drive shaft to rotate, the drive shaft drives the gear to rotate, the gear drives a set of gear rings to rotate, and with the cooperation of another set of gear rings and the limit ring, the gear ring drives the scraper to rotate. The scraper scrapes and cleans the scale on the inner wall of the storage tank. Then the wastewater can be discharged through the drain pipe at the bottom of the storage tank. This makes it convenient to rotate and scrape the scale on the inner wall of the storage tank, and improves the convenience of scale cleaning. Attached Figure Description

[0026] Example 1

[0027] Please see Figure 1-5This utility model provides an embodiment of a waste heat recovery device for lead alloy smelting flue gas in waste battery recycling, comprising a storage tank 1 and a valve body 8. The valve body 8 is disposed outside the storage tank 1, and a hydraulic cylinder 14 is movably mounted on the top of the valve body 8. The hydraulic cylinder 14 serves as a power drive, and a push arm 15 is mounted on the output end of the hydraulic cylinder 14. A connecting arm 17 is disposed at the end of the push arm 15 away from the hydraulic cylinder 14, and a linkage shaft 16 is disposed at the end of the connecting arm 17 near the push arm 15. The connecting arm 17 is movably connected to the push arm 15 through the linkage shaft 16. Next, a movable shaft 18 is fixedly provided at the end of the connecting arm 17 away from the push arm 15, and the movable shaft 18 extends into the valve body 8 and is movably connected to the valve body 8. A valve plate 19 is slidably provided inside the valve body 8, and the movable shaft 18 is connected to the valve plate 19. Two diversion pipes 20 are provided on the side wall of the valve body 8. Two sets of serpentine copper pipes 10 are symmetrically provided inside the liquid storage tank 1, and the serpentine copper pipes 10 are respectively connected to the diversion pipes 20. An exhaust port 5 is provided at the top of the liquid storage tank 1, and a liquid filling port 6 is provided at the top of the liquid storage tank 1 on one side of the exhaust port 5.

[0028] Water is injected into the storage tank 1 through the filling port 6, with the water level above the serpentine copper tube 10. Waste heat-containing flue gas is introduced into the valve body 8. The flue gas is transported through a set of channels within the valve body 8 and then through the diverter pipe 20 to the serpentine copper tube 10. The waste heat is conducted to the water through the serpentine copper tube 10, heating the water to generate steam. The steam is then transported to the turbofan generator through the exhaust port 5 to drive the blades and generate electricity, thus realizing the recovery and utilization of waste heat from the flue gas. If the serpentine copper tube 10 is damaged, to prevent equipment downtime, the hydraulic cylinder 14 is opened, causing the push arm 15 to move. The push arm 15, through the linkage shaft 16, drives the connecting arm 17 to rotate, which in turn drives the movable shaft 18 to rotate. The movable shaft 18 then drives the valve plate 19 to rotate, and the valve plate 19 removes the damaged... The corresponding channel of the serpentine copper tube 10 is blocked, and the flue gas is transported to another set of serpentine copper tubes 10 through another set of channels to ensure the normal recovery of flue gas waste heat. The flue gas is continuously transported to the inside of the filter box 2 through the serpentine copper tube 10, where the filter plate 21 filters the dust particles in the flue gas. The filtered gas is discharged through the outlet pipe 3. When the filter plate 21 needs to be replaced, the filter plate 21 is pulled upward. With the sliding cooperation of the limiting strip 22 and the limiting groove 23, the filter plate 21 can be removed from the inside of the filter box 2. Then, a new filter plate 21 can be installed back into the limiting groove 23. This realizes the flexible switching of the dual channels to transport flue gas and recover flue gas waste heat, which facilitates the quick disassembly and replacement of the filter plate and avoids the equipment shutdown caused by damage to the serpentine copper tube.

[0029] Limiting rings 7 are symmetrically arranged on the inner wall of the liquid storage tank 1, and toothed rings 11 are slidably arranged inside the limiting rings 7;

[0030] A stepper motor 4 is installed on the outer wall of the liquid storage tank 1. The stepper motor 4 serves as a power drive. A drive shaft 12 is installed at the output end of the stepper motor 4. A gear 13 is fitted on the surface of the drive shaft 12, and the gear 13 meshes with a set of gear rings 11.

[0031] Multiple sets of scrapers 9 are slidably arranged on the inner wall of the liquid storage tank 1 at equal intervals, and the two ends of the scrapers 9 are respectively connected to two sets of toothed rings 11.

[0032] Each end of the serpentine copper tube 10 is equipped with a filter box 2. Each filter box 2 has an air outlet pipe 3 on its side wall. Each filter box 2 has two sets of limiting grooves 23 inside. Each limiting groove 23 has a filter plate 21 inside. Each filter plate 21 has a limiting strip 22 symmetrically arranged on its side wall. The limiting strip 22 is slidably connected to the limiting groove 23.

[0033] When the water inside the storage tank 1 is heated, scale will condense on the inner wall of the storage tank 1. At this time, the stepper motor 4 is turned on, which drives the drive shaft 12 to rotate. The drive shaft 12 drives the gear 13 to rotate. With the movable cooperation of the limit ring 7 and the gear ring 11, the gear 13 drives a set of gear rings 11 to rotate. With the movable cooperation of the other set of gear rings 11 and the limit ring 7, the gear rings 11 drive the scraper 9 to rotate. The scraper 9 scrapes and cleans the scale on the inner wall of the storage tank 1. Afterwards, the wastewater can be discharged through the drain pipe at the bottom of the storage tank 1. This facilitates the rotation and scraping of scale on the inner wall of the storage tank and improves the convenience of scale cleaning.

[0034] Work steps

[0035] Water is injected into the storage tank 1 through the filling port 6, with the water level exceeding the serpentine copper tube 10. Waste heat-containing flue gas is introduced into the valve body 8. The flue gas is transported through a set of channels within the valve body 8 and then through the diversion pipe 20 to the serpentine copper tube 10. The waste heat is conducted to the water through the serpentine copper tube 10, heating the water to generate steam. The steam is then transported to the turbofan generator through the exhaust port 5 to drive the blades and generate electricity, thus realizing the recovery and utilization of waste heat from the flue gas. If a set of serpentine copper tubes... If tube 10 is damaged, to prevent equipment downtime, hydraulic cylinder 14 drives push arm 15 to move. Push arm 15 drives connecting arm 17 to rotate via linkage shaft 16. Connecting arm 17 drives movable shaft 18 to rotate. Movable shaft 18 drives valve plate 19 to rotate. Valve plate 19 blocks the channel corresponding to the damaged serpentine copper tube 10. Flue gas is then transported to another set of serpentine copper tubes 10 through another set of channels to ensure normal recovery of flue gas waste heat. Flue gas is continuously transported to the filter through serpentine copper tubes 10. Inside chamber 2, filter plate 21 filters dust particles in the flue gas. The filtered gas is discharged through outlet pipe 3. When filter plate 21 needs to be replaced, pull filter plate 21 upwards. With the sliding cooperation of limit strip 22 and limit groove 23, filter plate 21 can be removed from inside filter chamber 2. Then, replace it with a new filter plate 21 and install it back into limit groove 23. The water inside storage tank 1 will produce scale condensation on the inner wall of storage tank 1 after heating. At this time, open the stepper motor. Motor 4, driven by stepper motor 4, drives drive shaft 12 to rotate, drive shaft 12 to rotate gear 13 to rotate, gear 13 to rotate a set of gear rings 11, and with the movable cooperation of another set of gear rings 11 and limit ring 7, gear rings 11 drive scraper 9 to rotate, scraping and cleaning the scale on the inner wall of storage tank 1. Then the wastewater is discharged through the drain pipe at the bottom of storage tank 1. The above is the complete usage of the waste heat recovery device for alloy lead smelting flue gas in waste battery recycling.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
