Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of feeding devices, in particular to a feeding device and a nickel-iron leaching production line. Background Art
[0002] The lower hopper is commonly used in the daily production of wet leaching workshops in the field of new energy. It is a funnel-shaped container used to guide powdered materials into the reaction tank or reactor. In the nickel-iron leaching workshop, it is usually necessary to put the powder into the reaction tank or reactor through the lower hopper, but the powder will absorb water and agglomerate during storage, which will cause the discharge port to be blocked during discharge. During the discharge process, it will also adhere to the inner wall of the lower hopper, and as time goes by, the more powder accumulates, the more it will eventually block the discharge port. Production personnel usually use handheld tools to knock on the agglomerated materials or directly knock on the side wall of the lower hopper to clear it, but long-term operation will cause the side wall of the lower hopper to be uneven, which will further aggravate the blockage and have a certain impact on production. In severe cases, it may cause production interruption.
[0003] In view of this, the present utility model is proposed. Utility Model Content

[0039] For reference, the nickel-iron leaching production line may also include other equipment for material circulation, such as a transport device located upstream of the material discharge device, a reaction tank or a reaction kettle located downstream of the material discharge device, and the like.
[0040] Please refer to Figures 1 to 4 The material discharge device includes a shell 2, a material discharge hopper 1, a stirring member 4, a clamp-type handle butterfly valve 3 and a rotating shaft 5. The material discharge hopper 1 is movably connected to the shell 2 in the vertical direction. In the event of material blockage, the material discharge hopper 1 can move downward relative to the shell 2 after the weight increases. The bottom end of the material discharge hopper 1 is connected to a clamp-type handle butterfly valve 3 to facilitate material discharge control. The stirring member 4 is arranged at the bottom of the inner cavity of the material discharge hopper 1, and the rotating shaft 5 is connected to the stirring member 4. In the process of the material discharge hopper 1 moving downward, the rotating shaft 5 can be driven to rotate, thereby driving the stirring member 4 to rotate and stir the material, thereby avoiding material blockage.
[0041] In some optional embodiments, the above-mentioned feeding device includes a shell 2, a feeding hopper 1, a first transmission member 8, a reset member 11, a stirring member 4, a rotating shaft 5 and a second transmission member 6.

[0044] The reset member 11 is connected to the lower hopper 1 and the housing 2 at the same time. The reset member 11 is designed so that the lower hopper 1 can be restored to its original position after the blocked material is emptied.
[0045] It should be noted that the reset member 11 may be directly connected to the housing 2 , or may be indirectly connected to the housing 2 via other structures.

The second transmission member 6 is used to drive the rotating shaft 5 and the stirring member 4 to rotate under the reverse action of the first transmission member 8 when the lower hopper 1 moves upward or downward relative to the housing 2.
[0047] In the case of material blockage in the lower hopper 1, the lower hopper 1 moves downward under the weight, and the second transmission member 6 and the first transmission member 8 are in transmission cooperation. Since the position of the first transmission member 8 cannot change, the second transmission member 6 is driven in the reverse direction to rotate, thereby driving the rotating shaft 5 and the stirring member 4 to rotate. The stirring member 4 stirs and discharges the blocked material in the lower hopper 1 during the rotation process. After the discharge is completed, the weight of the lower hopper 1 becomes lighter, and the lower hopper 1 returns to its original position under the action of the reset member 11. Therefore, the above-mentioned discharge device can solve the problem of powder agglomeration and material blockage.
[0048] It should be noted that, in this embodiment, in order to facilitate the lower hopper 1 to slide up and down relative to the shell 2, specifically, the shell 2 is hollow to accommodate the lower hopper 1, and a circular groove is provided at the top of the shell 2, and the top of the lower hopper 1 is slidably connected to the side wall of the circular groove.
[0049] In order to facilitate transmission, in this embodiment, the first transmission member 8 is a rack fixedly arranged vertically on the housing 2, and the second transmission member 6 is a gear set and fixed on the rotating shaft 5, and the gears are meshed with each other. The gear is used to drive the rotating shaft 5 and the stirring member 4 to rotate under the action of the rack when the lower hopper 1 moves vertically relative to the housing 2. In addition, in other embodiments, the first transmission member 8 can also be a plate with a larger roughness, and the second transmission member 6 can be a roller.
[0050] In order to achieve the stability of the entire structure, in this embodiment, the stirring member 4 is arranged in the middle of the rotating shaft 5, the number of the first transmission members 8 can be two, and the two first transmission members 8 are respectively located on both sides of the lower hopper 1, and the number of the second transmission members 6 can be two, and the two second transmission members 6 are respectively installed at both ends of the rotating shaft 5.
[0051] In order to facilitate the limiting of the up and down movement of the lower hopper 1, in this embodiment, the lowering device also includes a limiting rod 9 and a limiting block 10. The limiting block 10 is fixedly connected to the lower hopper 1, one end of the limiting rod 9 is connected to the shell 2, and the limiting rod 9 can be slidably penetrated into the limiting block 10.
[0052] Specifically, the limiting block 10 forms a limiting groove, and the limiting rod 9 is slidably matched with the limiting groove. In order to further improve the stability of the limiting, the number of the limiting rod 9 and the limiting block 10 can be two, which are respectively located on both sides of the lower hopper 1.
[0053] In this embodiment, the reset member 11 is a spring, the reset member 11 is fitted with the limit rod 9, one end of the reset member 11 is connected to the limit block 10, and the other end of the reset member 11 is connected to the housing 2. Through the above arrangement, not only a stable limit process can be achieved, but also the reset member 11 can be used to achieve the reset process of the lower hopper 1. Similarly, in order to further improve the stability of the reset, the number of reset members 11 can be two, respectively located on both sides of the lower hopper 1.
[0054] In this embodiment, the material discharging device further includes a support block 7, which is fixedly connected to the housing 2, and the support block 7 is connected to the first transmission member 8 and the reset member 11 at the same time. In this solution, the reset member 11 is indirectly connected to the housing 2 through the support block 7. Similarly, in order to further improve the overall stability, the number of support blocks 7 can also be two, respectively located on both sides of the material discharging hopper 1.
[0055] In this embodiment, the stirring member 4 includes a roller mounted on the rotating shaft 5 and a plurality of stirring rods fixedly connected to the outer periphery of the roller. In addition, in other embodiments, an adapted stirring structure may also be selected.
[0056] In order to facilitate the rotational cooperation between the rotating shaft 5 and the lower hopper 1, in this embodiment, the lower hopper 1 further includes a bearing 12, and the lower hopper 1 is provided with a rotation hole, and part of the rotating shaft 5 is installed in the rotation hole through the bearing 12. It can be understood that the bottoms of the left and right sides of the lower hopper 1 are both provided with rotation holes, so as to facilitate the cooperation with the rotating shaft 5.
[0057] In order to achieve a better sealing effect and prevent the material from leaking from the position of the bearing 12, in this embodiment, the feeding device further includes a sealing ring 13, which seals the rotating shaft 5 and is located on the side of the bearing 12 close to the inner cavity of the feeding hopper 1. In this embodiment, the sealing ring 13 can be made of rubber material, for example.
[0058] In addition, in this embodiment, a buffer pad 14 is disposed at the bottom end of the housing 2. The buffer pad 14 is fixedly connected to the housing 2 so that it is not easy to fall off, thereby improving the stability of the housing 2.
[0059] According to the working principle of the feeding device provided in this embodiment:
[0060] When the material in the lower hopper 1 becomes compacted and causes material discharge blockage, the weight of the lower hopper 1 increases, and under the action of gravity, the lower hopper 1 moves downward, and the lower hopper 1 drives the rotating shaft 5 to move downward, and the rotating shaft 5 drives the second transmission member 6 to rotate through the first transmission member 8, and the second transmission member 6 drives the stirring member 4 to rotate through the rotating shaft 5. The stirring member 4 rotates to stir the compacted material, and the material can be discharged smoothly. As the material is discharged, the weight of the lower hopper 1 decreases, and the reset member 11 pushes the lower hopper 1 to return to its original position through the limit block 10.
[0061] The unloading device provided according to this embodiment has at least the following advantages:
[0062] In the daily production of the nickel-iron leaching workshop, it is necessary to put the powder into the reaction tank through the feeding device, and the feeding speed and agglomeration degree of the powder will affect the leaching reaction rate. The feeding device provided by the present embodiment can solve the problem of powder agglomeration. When the powder agglomerates block the discharge port, there is no need for manual knocking treatment, and the powder can be directly dispersed by mechanical stirring, thereby achieving normal production. At the same time, the cost of manually cleaning materials due to blockage is greatly reduced. Compared with other anti-blocking devices, such as adding an air hammer device, the feeding device is more economical. At the same time, the device has a small footprint, a simple structure, a simple principle, easy procurement of parts, low maintenance cost, safety and reliability, and flexible installation. It is very suitable for installation above the reaction tank and reactor.
[0063] In summary, in the material discharge device provided by the utility model, the lower hopper 1 is movably connected to the shell 2 in the vertical direction, so that in the event of material blockage, the lower hopper 1 can move downward relative to the shell 2 after the weight increases. The first transmission member 8 is arranged on the shell 2 and is located on the outside of the lower hopper 1. The reset member 11 is connected to the lower hopper 1 and the shell 2 at the same time. The design of the reset member 11 allows the lower hopper 1 to return to its original position after the blockage is cleared. The stirring member 4 is arranged at the bottom of the inner cavity of the lower hopper 1, the rotating shaft 5 is connected to the stirring member 4, and the end of the rotating shaft 5 is connected to the second transmission member 6, and the second transmission member 6 is in transmission cooperation with the first transmission member 8. Among them, the second transmission member 6 is used to drive the rotating shaft 5 and the stirring member 4 to rotate under the reverse action of the first transmission member 8 during the upward or downward movement of the lower hopper 1 relative to the shell 2. Therefore, when the lower hopper 1 is blocked, the lower hopper 1 moves downward under the weight, and the second transmission member 6 and the first transmission member 8 are matched with each other. Since the position of the first transmission member 8 cannot change, the second transmission member 6 is driven in reverse to rotate, thereby driving the rotating shaft 5 and the stirring member 4 to rotate. During the rotation, the stirring member 4 stirs and discharges the blocked material in the lower hopper 1. After the discharge is completed, the weight of the lower hopper 1 becomes lighter. Under the action of the reset member 11, the lower hopper 1 returns to its original position, thereby solving the problem of powder agglomeration and blockage.
[0064] The feeding device occupies a small area, has a simple structure, is flexible to install, is safe and reliable, and is very suitable for installation above a reaction tank or a reaction kettle.
[0065] The nickel-iron leaching production line with the above-mentioned feeding device can solve the problem of powder agglomeration and blocking. When the powder agglomeration blocks the discharge port, it does not need to be manually knocked, and the powder can be directly dispersed by mechanical stirring, thereby achieving normal production. In addition, the nickel-iron leaching production line can also have a higher leaching reaction rate.
[0066] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
