Description

Technical Field

[0001] This utility model relates to the field of zinc diffusion processing technology, specifically a zinc powder separation and recovery device for zinc diffusion processing. Background Technology

[0002] Zinc diffusion is a metal surface treatment process that involves immersing steel products in molten zinc, causing a chemical reaction between the zinc and the steel surface to form a zinc layer. Zinc diffusion produces some unused zinc powder. To achieve resource recycling and environmental protection, zinc powder separation and recovery devices are typically used to recycle the waste zinc powder. These devices usually include separation equipment, filtration devices, and recovery systems. Through the coordination and cooperation of these components, the zinc powder can be recycled.

[0003] In the prior art, Chinese Patent No. CN116765088B discloses a zinc powder separation and recovery device for zinc diffusion processing, belonging to the field of zinc diffusion processing. Its key technical features include a base on which a reaction vessel is mounted. A heating jacket is installed at the lower end of the reaction vessel. A solution tank is mounted on the upper surface of the base. A screening mechanism is installed at the upper end of the reaction vessel. A separation mechanism is installed inside the reaction vessel. The screening mechanism includes a screening box, a feed hopper, and an iron separator. The separation mechanism includes a holding tank, a suction pump, a discharge channel, a discharge valve, and a stirrer. The beneficial effect of this invention is that the screening box can first screen out waste materials larger than zinc powder. The remaining waste material is poured into the holding tank inside the reaction vessel. Dilute hydrochloric acid is added to the reaction vessel, and the zinc powder in the remaining waste material is separated through a chemical reaction. Then, the remaining waste material is discharged through the discharge channel, and the solution in the reaction vessel is removed, thus facilitating the separation and recovery of zinc powder and saving resources.

[0004] Currently, most zinc powder separation and recovery devices on the market still have certain shortcomings in use. As shown in the document above, adding dilute hydrochloric acid into the reactor allows for the separation of zinc powder from the remaining waste through a chemical reaction. However, the reactor vibrates during use, which affects the stability of the equipment and accelerates the wear of internal parts. Furthermore, replacing the stirring rod of the reactor is time-consuming and affects the processing efficiency of zinc powder. Therefore, these devices have certain shortcomings in use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a zinc powder separation and recovery device for zinc diffusion processing, including a vibrating screen device, a conveying device connected to the side of the vibrating screen device, a reaction vessel connected to the side of the conveying device, a stirring rod installed inside the reaction vessel, and a support leg fixed at the bottom of the reaction vessel;

[0007] The end of the output device of the reactor is fixed with a fixed block. The fixed block is provided with a pressing mechanism for replacing the stirring rod.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0029] When the device is in use, the material to be processed is placed inside the vibrating screen device 1 for vibrating and screening. The processed material after vibrating and screening can fall onto the surface of the conveying device 2 and be transported to the reactor 3 by the conveyor belt of the conveying device 2. The required chemical liquid is added to the reactor 3 to react with the processed material, thereby achieving the separation of zinc powder.

[0030] Example 1: As Figures 1-4 The present invention provides the following technical solution to address the problem of cumbersome and time-consuming replacement of the stirring rod 4 in the separation and recovery device: A pressing mechanism is disclosed.

[0031] The device includes a vibrating screen 1, a conveying device 2 connected to the side of the vibrating screen 1, a reaction vessel 3 connected to the side of the conveying device 2, a stirring rod 4 installed inside the reaction vessel 3, a support leg 5 fixed to the bottom of the reaction vessel 3, a fixing block 301 fixed to the end of the output device of the reaction vessel 3, and a pressing mechanism for replacing the stirring rod 4 inside the fixing block 301. The pressing mechanism includes an insertion groove 302, which is located at the bottom of the fixing block 301. A sliding groove 303 is provided at the bottom of the fixing block 301 near the insertion groove 302. A sliding block 304 slides through the sliding groove 303. A pressing block 305 is fixed to the bottom of the sliding block 304. A threaded sleeve 306 is threadedly connected to the surface of the fixing block 301. A pressing groove 307 is symmetrically provided on the side of the stirring rod 4. A connecting seat 501 is connected to the bottom of the support leg 5. A shock-absorbing mechanism for protecting the recycling device is provided inside the connecting seat 501. The fixing block 301 and the threaded sleeve 306 are threadedly connected. 304 and the sliding groove 303 are slidably connected. The sliding block 304 and the extrusion block 305 are an integral structure. The extrusion block 305 and the extrusion groove 307 are snap-fit ​​connected. When the recycling device needs to disassemble and replace the stirring rod 4, the threaded sleeve 306 can slide downward through the fixed block 301. After the threaded sleeve 306 slides to a certain position, it pulls the stirring rod 4. When the stirring rod 4 is pulled, it can drive the extrusion groove 307 to move. When the extrusion groove 307 moves, the inclined surface can extrude the extrusion block 305. When the extrusion block 305 is extruded, it can drive the sliding block 304 to move. When the extrusion block 305 moves, it can slide through the sliding groove 303. After the extrusion block 305 slides out of the extrusion groove 307, the stirring rod 4 can slide through the insertion groove 302. When the stirring rod 4 slides out of the insertion groove 302, it can be disassembled and replaced, which improves the efficiency of disassembling and replacing the stirring rod 4 of the recycling device, and indirectly improves the recycling efficiency of the device for zinc powder.

[0032] Example 2: Figure 1 , Figure 2 , Figure 5 and Figure 6 The present invention provides the following technical solution to address the problem that vibrations generated during the operation of the reaction vessel 3 in the separation and recovery device accelerate the wear of internal parts, thereby affecting its service life: A vibration damping mechanism is disclosed.

[0033] The shock absorption mechanism includes a movable groove 502, which is located at the top of the connecting seat 501. Three telescopic grooves 503 are provided on the side of the movable groove 502. Springs 504 are connected inside the telescopic grooves 503, and telescopic blocks 505 are connected to the ends of the springs 504. Limiting grooves 506 are symmetrically provided on the side of the support leg 5. Limiting blocks 507 slide through the limiting grooves 506 and are fixed inside the movable grooves 502. The movable groove 502 and the support leg 5 are slidably connected. The telescopic blocks 505 and the telescopic grooves 503 form a telescopic structure through the springs 504. The limiting grooves 506 and the limiting blocks 507 are slidably connected. When the reactor 3 of the recovery device operates, it will vibrate. When the reactor 3 vibrates, it can cause the support leg 5 to move downwards and impact. When the device moves, it can move the limiting groove 506. When the limiting groove 506 moves, it can slide through the limiting block 507. When the support leg 5 slides, its bottom end can press against the inclined surface of the three telescopic blocks 505. When the telescopic block 505 is pressed, it can slide through the movable groove 502 and the telescopic groove 503. When the telescopic block 505 slides, it can press against the spring 504. When the spring 504 is pressed, it can deform and generate a reaction force. The reaction force of the spring 504 can generate a thrust on the telescopic block 505. The thrust can attenuate the downward impact force of the support leg 5. When the impact force is reduced, the vibration of the reactor 3 can be reduced, thereby protecting the internal components of the reactor 3, reducing wear and tear, and indirectly improving the service life and quality of the device.

[0034] Example 3: Figure 6 The present invention provides the following technical solution to address the potential inadequacy of the damping effect of the damping mechanism in the reactor 3: Based on Embodiment 2, a friction mechanism is disclosed:

[0035] The connecting seat 501 also has a friction mechanism inside to improve the shock absorption effect of the spring 504. The friction mechanism includes a placement groove 508, which is opened on the side of the movable groove 502. A compression air ring 509 is connected inside the placement groove 508. An air cushion 510 is connected inside the telescopic groove 503 near the spring 504. A connecting pipe 511 connects the compression air ring 509 and the air cushion 510. When the shock absorption mechanism of the recovery device is in use, the support leg 5 will generate a downward impact force. Through the impact force, the telescopic block 505 can slide inside the telescopic groove 503. When the telescopic block 505 slides, it can compress the air cushion 510. When the air cushion 510 is compressed, it can deform. When the air cushion 510 deforms, it can release the internal gas. The gas is delivered to the squeezing ring 509 through the connecting pipe 511. The gas delivery rate is reduced to the downward impact force of the support leg 5. The gas delivered to the squeezing ring 509 can expand inside the placement groove 508. When the squeezing ring 509 expands to the side of the support leg 5, it can squeeze it. When the support leg 5 is squeezed, the downward impact force can be further reduced. At the same time, the greater the squeezing force on the air cushion 510, the greater the frictional squeezing force generated by the squeezing ring 509 on the support leg 5. This can greatly improve the shock absorption effect of the recovery device. In addition, the frictional squeezing of the squeezing ring 509 can also prevent the elastic vibration generated when the spring 504 elastically resets, improve the stability of the reactor 3 during use, and make it more convenient to use.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
