Technical Field
[0001] This utility model relates to the technical field of recycled lead processing equipment, and specifically discloses a waste heat recovery device for recycled lead metallurgy. Background Technology
[0002] Recycled lead is a lead product obtained by recycling waste lead products or lead scrap and processing and refining them. The production process of recycled lead mainly includes waste collection, sorting, crushing, smelting and refining. In order to save resources, waste heat recovery devices are usually used in the process of recycled lead processing to recover the heat emitted by lead slag and improve resource utilization.
[0003] Chinese patent CN211717199U discloses a waste heat recovery device for recycled lead smelting. It includes a cylindrical body, with a sleeve fixed to the middle of the lower end of the cylindrical body. A telescopic cylinder is fixed inside the sleeve, with its telescopic rod extending through the upper end of the sleeve to its exterior. A conical hopper is fixed inside the cylindrical body above the sleeve, and a concentric conical cylinder is arranged inside the hopper. The outer edge of the conical cylinder contacts the inner edge of the lower port of the conical hopper. Multiple through holes with outlet ends facing the conical hopper are opened on the side wall of the conical cylinder. The telescopic rod of the telescopic cylinder extends into the conical cylinder and is fixedly connected thereto. A feed pipe and an air outlet pipe are fixed to the upper end of the cylindrical body, and a discharge pipe is fixed to the lower end of the cylindrical body. An air inlet pipe communicating with the interior of the conical hopper is fixed to the cylindrical body below the conical hopper. This invention can recover and utilize the heat in lead slag with a high heat recovery rate and convenient loading and unloading. However, in the above-mentioned device, the airflow blown into the cylinder through the air inlet pipe is difficult to enter the cone, which causes the airflow to be unable to pass smoothly through the through hole and blow to the high-temperature lead slag, affecting the quality of airflow heat transfer. In the above-mentioned device, it is not convenient to clean the lead slag remaining at the bottom of the cylinder during the discharge process. Therefore, in order to solve the above problems, this invention proposes a waste heat recovery device for recycled lead metallurgy. Utility Model Content

It also allows the user to monitor the temperature in the cavity between the hopper, the outer shell, and the top plate, so that when the temperature drops or returns to normal, the telescopic rod can be extended in time to discharge the lead slag from the hopper.
[0009] As a further feature of the above scheme, a support is provided on the outer side of the cylinder to provide stable support for the cylinder and its connecting components.

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The following will refer to the appendix... Figures 1-5 This application will be described in detail with reference to the embodiments.
[0026] An embodiment discloses a waste heat recovery device for recycled lead metallurgy, including a storage mechanism 1 and an air supply mechanism 2. The air supply mechanism 2 is arranged inside the storage mechanism 1. The storage mechanism 1 includes a cylinder 11, and a hopper 12 is connected to the inner side of the cylinder 11. Two discharge pipes 13 are symmetrically arranged below the cylinder 11. The air supply mechanism 2 includes a cone 21, and a cone cylinder 22 is arranged below the cone 21. A telescopic sleeve 25 is connected to the lower part of the cone cylinder 22, and a sleeve 24 is connected to the lower part of the telescopic sleeve 25. The sleeve 24 and the telescopic sleeve 25 are both internally connected. The cylinder 11 has a telescopic rod 23. An inspection tube 14 is connected to the lower end of one side of the cylinder 11. A blocking plate 15 is provided at one end of the inspection tube 14. A reserved hole 111 is provided in the lower middle part of the cylinder 11. A base 231 is connected to the lower end of the telescopic rod 23. The base 231, sleeve 24, telescopic sleeve 25 and cone 22 are all concentrically arranged with the reserved hole 111. A plurality of air outlet holes 221 arranged in a circumferential array are provided at the upper end of the cone 22. An air inlet pipe 26 is connected to the lower middle part of the cylinder 11. A fan 27 is connected to the end of the air inlet pipe 26 away from the cylinder 11.
[0027] like Figure 1 and Figure 2As shown, a top plate 16 is connected to the top of the cylinder 11, a feed pipe 17 is connected to the upper middle part of the top plate 16, and an air outlet pipe 18 is connected to the upper side of the top plate 16, which facilitates the installation and maintenance of the above components.
[0028] like Figure 1 and Figure 2 As shown, a camera 4 is connected to the side of the top plate 16 away from the exhaust pipe. A temperature sensor 5 is installed on one side of the camera 4. Both the camera 4 and the temperature sensor 5 are connected to the terminal equipment via electrical signals, which allows the user to monitor the amount of lead slag in the hopper 12 so as to adjust the usage rhythm of the device in a timely manner. It also allows the user to monitor the temperature in the cavity between the hopper 12, the outer shell and the top plate 16 so as to control the extension rod 23 to extend and discharge the lead slag from the hopper 12 when the temperature drops or returns to normal.
[0029] like Figure 1 and Figure 2 As shown, a support 3 is provided on the outer side of the cylinder 11, which can provide stable support for the cylinder 11 and its connecting parts. A controller 6 is provided on one side of the support 3 to facilitate the control of the operation of related components in the device.
[0030] like Figure 1 , Figure 3 and Figure 4 As shown, the inspection tube 14 has two symmetrically arranged sliding grooves 141 at one end near the cylinder 11. The two ends of the blocking plate 15 are respectively slidably engaged with the two sliding grooves 141, which facilitates the disassembly and assembly of the blocking plate 15.
[0031] like Figure 2 and Figure 5 As shown, the base 231 is detachably connected to the bottom of the cylinder 11, which facilitates the installation and maintenance of the base 231 and its connected telescopic rod 23. The end of the air inlet pipe 26 away from the fan 27 is aligned with the reserved hole 111. The air inlet pipe 26, the base 231, the sleeve 24, the telescopic sleeve 25 and the cone 22 are internally connected, which can ensure that the fan 27 can smoothly inject the airflow outside the cylinder 11 into the cone 22 through the air inlet pipe 26, the base 231, the sleeve 24 and the telescopic sleeve 25.
[0032] The waste heat recovery device for recycled lead metallurgy disclosed in this embodiment connects the existing equipment that can utilize the heat of high-temperature steam to the exhaust pipe 18 before use. Sufficient high-temperature lead slag is injected into the hopper 12 in the cylinder 11 through the feed pipe 17. At this time, the lower open end of the hopper 12 contacts the outer side of the cone 22, which can seal the high-temperature lead slag. After contacting the cone 21, the high-temperature lead slag is evenly dispersed in the hopper 12. The controller 6 is used to start the fan 27, causing the fan 27 to inject ambient temperature air from outside the cylinder 11. The ambient air injected into the intake pipe 26 passes through the reserved hole 111 and then sequentially through the base 231, sleeve 24, and telescopic sleeve 25 into the cone 22. It is then blown through the exhaust hole 221 towards the high-temperature lead slag, where it undergoes heat transfer, absorbing the heat generated by the high-temperature lead slag and becoming high-temperature air. This high-temperature air rises and is discharged through the exhaust pipe 18 into the existing equipment. After a period of time, the temperature transmitted back to the terminal equipment by the temperature sensor 5 is observed. When the temperature drops to near room temperature, the controller 6... With the blower 27 off, the controller 6 is used to extend the telescopic rod 23, stretching the telescopic sleeve 25 and causing the cone 22 to move upward. As the cone 22 moves upward, the gap between the cone 22 and the hopper 12 gradually increases. Under the influence of gravity, the cooled lead slag falls through the gap between the cone 22 and the hopper 12 into the cavity formed between the hopper 12 and the cylinder 11, and is discharged from the cylinder 11 through the discharge pipe 13. The amount of lead slag inside the hopper 12 is observed by the camera 4 on the terminal equipment. In the video, when the lead slag in hopper 12 is discharged, the controller 6 is used to control the telescopic rod 23 to retract. When the cone 22 contacts the hopper 12, the controller 6 closes the telescopic rod 23, pulls the blocking plate 15 out from the two slide grooves 141, inserts the tool from the inspection tube 14 into the cylinder 11 to clean the lead slag remaining at the bottom of the cylinder 11 into the discharge pipe 13, resets the blocking plate 15, and injects the high-temperature lead slag into the hopper 12 again through the feed pipe 17. The above operation is repeated to continue the waste heat recovery operation of high-temperature lead slag.
[0033] The camera 4, temperature sensor 5, controller 6, cylinder 11, hopper 12, discharge pipe 13, feed pipe 17, air outlet pipe 18, cone 21, cone cylinder 22, telescopic rod 23, sleeve 24, telescopic sleeve 25, air inlet pipe 26, and fan 27 in the waste heat recovery device for recycled lead metallurgy disclosed in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.
[0034] The above are merely preferred embodiments of the present utility model and are 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.
