[0033] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of an acid-process lithium slag desulfurization and recovery treatment device.
[0034] like Figures 1-9As shown, this utility model includes a desulfurization recovery treatment device body 1. On the right side of the desulfurization recovery treatment device body 1, a liquid storage device 2 flush with the ground, a water pump 21, and a filter device 3 are sequentially installed. The top of the filter device 3 has a feed pipe for easy feeding, while the bottom of the filter device 3 has a discharge pipe for easy discharge and a waste liquid recovery pipe. It can be connected to an external impurity pump, etc., for material intake and waste liquid removal. The inlet and outlet of the water pump 21 are connected to the liquid storage device 2 and the filter device 3 respectively via pipelines. The liquid used for deacidification of lithium slag is conveniently transported to the filtration device 3 for desulfurization treatment via the liquid storage device 2. The filtration device 3, the desulfurization recovery treatment device body 1, and the liquid storage device 2 work together. Cleaning components 4 are provided on both sides of the filtration device 3. Each cleaning component 4 includes a fixed box 41. Two symmetrically arranged rotating rods 42 are rotatably connected to the inner cavity of the fixed box 41. One end of each rotating rod 42 extends into the inner cavity of the filtration device 3 and is fixedly connected to a filter element 43. The contact area between the rotating rods 42 and the filtration device 3 is sealed. The filter element 43 can be made of a material that intercepts the dissolved lithium slag, such as a filter screen or activated carbon plate. Two first pulleys 44 are respectively fitted onto the surfaces of the two rotating rods 42, and the two first pulleys 44 are connected by a belt drive. A first motor 47 is installed inside the fixed box 41, and the output shaft of the first motor 47 is connected to one end of the rotating rod 42. Two symmetrically arranged welding boxes 45 are fixedly connected to the rear surface of the filtration device 3. The inner cavity of the welding boxes 45 rotates... A round rod 46 is connected to the inner cavity of the welding box 45, and a stepper motor 428 is installed therein. The output shaft of the stepper motor 428 is connected to the top end of the round rod 46. The surface of the round rod 46 located on the right side is provided with external threads. A movable plate 48 is movably connected to the surface of the round rod 46. The area where the movable plate 48 contacts the round rod 46 on the right side is provided with a matching internal thread. A through cavity is opened on one side opposite to the two welding boxes 45. The left and right sides of the movable plate 48 are slidably connected to the inner cavity of the welding box 45. A connecting rod 49 is fixedly connected to the top of the movable plate 48.
[0035] like Figures 2-9As shown, the end of the connecting rod 49 away from the moving plate 48 penetrates into the inner cavity of the filter device 3 and is fixedly connected to two storage boxes 410 arranged symmetrically front to back. The area of the connecting rod 49 in contact with the filter device 3 is sealed. A motor 411 is installed in the inner cavity of the storage box 410. The motor 411 is waterproof. The left and right sides of the inner cavity of the storage box 410 are rotatably connected to the running rod 412. The surface of the running rod 412 and the output shaft of the motor 411 are respectively connected to two meshing bevel gears 413. The surface of the running rod 412 is fixedly connected to two cams 414 arranged symmetrically from left to right. Guide plates 415 are slidably connected to the left and right sides of the inner cavity of the storage box 410. The surface of the guide plate 415 is fixedly connected to a protrusion 416 that contacts the cam 414. The side of the guide plate 415 away from the protrusion 416 is fixedly connected to a push rod 417. A return spring 4 is sleeved on the surface of the push rod 417. 18. The two ends of the return spring 418 are fixedly connected to the surface of the guide plate 415 and the inner cavity of the storage box 410, respectively. One end of the top rod 417 passes through to the outside of the storage box 410 and is fixedly connected to the cleaning plate 419. The area of the top rod 417 in contact with the storage box 410 is sealed. The cleaning plate 419 is used in conjunction with the filter component 43. The surfaces of the left and right sides of the filter device 3 are fixedly connected to the protective box 420. The inner cavity of the protective box 420 is equipped with the second motor 421. The front and rear sides of the inner cavity of the protective box 420 are rotatably connected to the positioning rod 422. One end of the positioning rod 422 passes through to the inner cavity of the filter device 3. The area of the positioning rod 422 in contact with the filter device 3 is sealed. The inner cavity of the protective box 420 is rotatably connected to the short rod 427. The surfaces of the short rod 427 and the positioning rod 422 are respectively equipped with the second pulley 423, and the two second pulleys 423 are connected by belt drive.
[0036] like Figures 3-9 As shown, two meshing gears 424 are respectively connected to the surface of the positioning rod 422 and the surface of the short rod 427. A water pipe 425 is installed in the inner cavity of the positioning rod 422, and one end of the water pipe 425 extends to the outside of the protective box 420. The water pipe 425 is connected to an external clean water storage device to facilitate the entry of clean water to spray and clean the filter component 43. Several nozzles 426 are installed on the surface of the water pipe 425.
[0037] Specifically, when the filter element 43 has been used for an extended period, the system activates the first motor 47, which drives the rotating rod 42 to rotate, thereby causing the first pulley 44 to rotate. The rotation of the first pulley 44 causes all rotating rods 42 to rotate synchronously, ultimately causing the filter element 43 to flip to a vertical position. Subsequently, the stepper motor 428 is activated, which pushes the moving plate 48 up and down via the threaded transmission principle through the round rod 46. The movement of the moving plate 48 is transmitted to the storage box 410 through the connecting rod 49, causing the storage box 410 to drive the cleaning plate 419 to clean the front and rear surfaces of the filter element 43. During the cleaning process, the motor 411 drives the bevel gear 413 to rotate, further driving the running rod 412 and the cam 414 to rotate. The rotation of the cam 414 pushes the protrusion 416 and the guide plate 415 to move back and forth, and achieves a vibration cleaning effect through the push rod 417 and the cleaning plate 419. At the same time, the return spring 418 ensures the return of the guide plate 415, effectively removing residues from the pores of the filter element 43.
[0038] Simultaneously, the first motor 47 drives the short rod 427 to rotate, which not only causes the gear 424 to mesh and rotate, but also drives the second pulley 423 to rotate. The second pulley 423 drives the positioning rod 422 to rotate, while the gear 424 drives the other positioning rod 422 to rotate in the opposite direction, causing the nozzles 426 on the two positioning rods 422 to rotate relative to or opposite to each other, achieving effective spray cleaning of the filter element 43. After cleaning is completed, the storage box 410 is first moved back to the top of the inner cavity of the filter device 3, and then the filter element 43 is flipped back to its original position for subsequent use, ensuring the cleanliness and working efficiency of the filter element 43 and extending its service life.
[0039] The working principle of an acid-process lithium slag desulfurization and recovery treatment device is as follows: The user first puts lithium slag, such as lithium sulfate and calcium sulfate, into the filter device 3. Then, with the cooperation of the liquid storage device 2 and the water pump 21, the liquid is discharged into the filter device 3 to desulfurize the lithium slag. Taking advantage of the fact that calcium sulfate is slightly soluble in water, the lithium slag is repeatedly desulfurized. After desulfurization, the waste liquid after desulfurization is discharged first, and then the desulfurized lithium slag is recovered. During the lithium slag recovery process, the filter component 43 is flipped by the cleaning component 4 so that it is in a vertical state and falls to the bottom of the inner cavity of the filter device 3 for discharge. After the filter component 43 has been used for a long time, the filter component 43 is rinsed and cleaned by the cleaning component 4 for easy use.
[0040] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
