[0031] The utility model provides a transition silo and batching equipment. A plurality of embodiments are given below to describe in detail the transition silo and batching equipment provided by the utility model.
[0032] Example 1
[0033] The transition silo provided in this embodiment is as follows: Figures 1 to 5 As shown, it includes a silo body 1, a fan shut-off fan 3 and a discharge pipe 2; a discharge port 13 is provided at the bottom end of the silo body 1, and the discharge port 13 is connected to the discharge pipe 2 through the fan shut-off fan 3.
[0034] The discharge port 13 is connected to the discharge pipe 2 through the fan 3. The fan 3 can buffer the material to prevent the material from directly accumulating without restriction at the connection between the discharge port 13 and the discharge pipe 2, and can prevent the discharge port 13 from being blocked, thereby ensuring that the transition silo continuously outputs materials to the rear end, thereby ensuring the continuous operation of the entire batching equipment.
[0035] Specifically, a accommodating cavity is formed inside the silo body 1, and a plurality of feed ports 12 connected to the accommodating cavity are provided at the top of the silo body 1, wherein the plurality of feed ports 12 include a main material feed port 12 and three auxiliary material feed ports 12; a discharge port 13 connected to the accommodating cavity is formed at the bottom of the silo body 1, and the discharge port 13 is connected to the relevant fan 3, and the discharge port 13 is connected to the discharge pipe 2 through the fan 3.
[0036] The discharge port 13, the air shut-off fan 3 and the discharge pipe 2 are fixedly connected in sequence, and the connection method can be a non-detachable fixed connection, such as bonding or welding, or a detachable fixed connection, such as a snap-on or threaded connection.
[0037] Furthermore, the air shut-off fan 3 includes a cylinder 31, a driving device 34, a rotating shaft 32 and a rotating block 33; the top end of the cylinder 31 is connected to the discharge port 13, and the bottom end of the cylinder 31 is connected to the discharge pipe 2; one end of the rotating shaft 32 is connected to the driving device 34, and the other end of the rotating shaft 32 extends into the cylinder 31, and the axis of the rotating shaft 32 is perpendicular to the axis of the silo body 1; the rotating block 33 is sleeved on the rotating shaft 32; a plurality of groove structures 332 are provided on the outer side wall of the rotating block 33, and the plurality of groove structures 332 are arranged at intervals along the circumference of the rotating block 33.
[0038] The barrel 31 is coaxially arranged with the silo body 1, and the top and bottom ends of the barrel 31 are both open structures. The top end of the barrel 31 is connected with the discharge port 13, and the bottom end of the barrel 31 is connected with the discharge pipe 2. The rotating block 33 is coaxially arranged with the rotating shaft 32, and the rotating block 33 is fixedly sleeved on the rotating shaft 32, and the rotating block 33 is located below the discharge port 13. The driving device 34 is fixedly arranged on the outside of the barrel 31, one end of the rotating shaft 32 is connected to the driving device 34, and the other end of the rotating shaft 32 passes through the barrel 31 and extends into the inside of the barrel 31. The driving device 34 can drive the rotating shaft 32 to rotate around the axis of the rotating shaft 32.
[0039] When any groove structure 332 rotates to a position opposite to the discharge port 13, the material falls into the groove structure 332, and the material in the groove structure 332 rotates with the rotating block 33. When the groove structure 332 rotates to a position opposite to the bottom end of the cylinder 31, the material falls into the opening structure at the bottom end of the cylinder 31, and then falls into the discharge pipe 2.
[0040] The amount of material contained in the groove structure 332 is the amount of material transported by the rotating block 33 in each cycle (the time it takes for each groove structure 332 to rotate from the top of the cylinder 31 to the bottom of the cylinder 31). The material will not accumulate directly at the connection between the discharge port 13 and the discharge pipe 2 without restriction, which can effectively prevent the discharge port 13 from being blocked, ensure that the transition silo continuously outputs materials to the rear end, and thus ensure the continuous operation of the entire batching equipment.
[0041] Preferably, the plurality of groove structures 332 are evenly spaced along the circumference of the rotating block 33 , so that the plurality of groove structures 332 can convey materials to the discharge pipe 2 at the same time.
[0042] The driving device 34 may be an electric motor, or a pneumatic motor or any other suitable device.
[0043] The groove structure 332 can be directly formed on the outer wall of the rotating block 33, or convex strips 331 can be provided on the outer wall of the rotating block 33 so that the groove structure 332 is formed between adjacent convex strips 331. The cross section of the outer wall of the rotating block 33 can be circular, polygonal or any other suitable shape.
[0044] Furthermore, a plurality of ridges 331 are provided on the outer wall of the rotating block 33 , and the plurality of ridges 331 are arranged at intervals along the circumference of the rotating block 33 . The extension direction of each ridge 331 is parallel to the axial direction of the rotating block 33 , and a groove structure 332 is formed between two adjacent ridges 331 .
[0045] The extension direction of each convex strip 331 is parallel to the axial direction of the rotating block 33. Along the axial direction of the rotating block 33, the two ends of each convex strip 331 are flush with the two ends of the rotating block 33 respectively. The multiple convex strips 331 are evenly spaced along the circumference of the rotating block 33, and a groove structure 332 is formed between two adjacent convex strips 331, so that the multiple groove structures 332 are evenly spaced along the circumference of the rotating block 33.
[0046] Furthermore, the outer diameter of the rotating block 33 is A, the inner diameter of the cylinder 31 is B, A>B; along the radial direction of the cylinder 31 perpendicular to the axial direction of the rotating block 33, the inner wall of the cylinder 31 is provided with two oppositely arranged grooves 311, and the grooves 311 are surrounded by the outer side of the rotating block 33.
[0047] In this embodiment, along the radial direction of the rotating block 33, the outer side wall of the rotating block 33 has two convex strips 331 arranged opposite to each other, and the distance between the outer surfaces of the two convex strips 331 is the outer diameter of the rotating block 33. Since A>B, the rotating block 33 can better block the communication between the top and the bottom of the cylinder 31, and prevent the material from leaking from the top of the cylinder 31 to the bottom of the cylinder 31 without passing through the groove structure 332. In the process of the material rotating with the groove structure 332, the groove structure 332 rotates 45° from the position relative to the top of the cylinder 31, and the material can gradually fall into the bottom of the cylinder 31, which can ensure that a preset amount of material enters the discharge pipe 2 through the bottom of the cylinder 31 in each cycle, thereby effectively preventing the connection between the discharge port 13 and the discharge pipe 2 from being blocked.
[0048] The inner wall of the cylinder 31 is provided with two oppositely arranged grooves 311, and the grooves 311 are arranged around the outside of the rotating block 33. The setting of the grooves 311 can ensure that during the rotation of the rotating block 33, the outer surface of the rotating block 33 does not interfere with the inner wall of the cylinder 31, thereby preventing the rotating block 33 from being unable to rotate.
[0049] Furthermore, the groove 311 is an arc-shaped groove 311 .
[0050] The groove 311 is an arc-shaped groove 311, which can fit more closely with the outer surface of the cylinder 31, reduce the gap between the two, and improve the performance of preventing materials from leaking from the top end of the cylinder 31 to the bottom end while ensuring that the rotating block 33 can rotate.
[0051] The arc-shaped groove 311 may be in contact with the convex strip 331 , or there may be a gap of less than 2 mm between the arc-shaped groove 311 and the convex strip 331 .
[0052] In addition, along the axial direction of the rotating block 33, the inner wall of the cylinder 31 is provided with two oppositely arranged concave structures, and the two ends of the rotating block 33 respectively extend into the two concave structures, so as to prevent material leakage from the two end areas along the axial direction of the rotating block 33 while ensuring that the rotating block 33 can rotate.
[0053] Furthermore, an iron removal structure 14 is provided inside the silo body 1 . The iron removal structure 14 is arranged above the discharge port 13 . The iron removal structure 14 can absorb iron filings.
[0054] Specifically, one end of the iron removal structure 14 is fixedly connected to the outer surface of the silo body 1, and the other end of the iron removal structure 14 extends into the accommodating cavity inside the silo body 1. The iron removal structure 14 is arranged above the discharge port 13. The iron removal structure 14 can absorb iron filings in the material to remove the iron filings in the material; since some iron filings may fall into the material during the transportation process, and for the slurry coated on the surface of the electrode sheet, the mixed iron filings will affect the quality of the slurry, so the iron removal structure 14 is used to remove the iron filings mixed in the material, thereby improving the quality of the slurry batched by the batching equipment.
[0055] The iron removal structure 14 can be a magnetic block, a magnetic bar or any other suitable form.
[0056] Furthermore, a vibrating hammer 11 is provided on the outer side wall of the silo body 1 , and the vibrating hammer 11 is arranged in the middle and lower part of the silo body 1 .
[0057] At least one vibrating hammer 11 is provided on the outer wall of the silo body 1, and the vibrating hammer 11 can vibrate the silo body 1 to prevent the material from piling up on the inner wall of the silo body 1. In addition, the middle and lower part of the silo body 1 is prone to material accumulation, and the vibrating hammer 11 is provided in the middle and lower part of the silo body 1, which can better prevent the silo body 1 from piling up.
[0058] Furthermore, the silo body 1 is conical; along the axial direction of the silo body 1, the diameter of the silo body 1 gradually decreases from the top to the bottom of the silo body 1, that is, along the axial direction of the silo body 1, the cross-sectional area of the silo body 1 gradually decreases from the top to the bottom of the silo body 1.
[0059] Example 2
[0060] The batching equipment provided in this embodiment includes the transition silo provided in embodiment 1. The discharge port 13 is connected to the discharge pipe 2 through the fan 3, and the fan 3 can buffer the material to prevent the material from directly accumulating without restriction at the connection between the discharge port 13 and the discharge pipe 2, and can prevent the discharge port 13 from being blocked, thereby ensuring that the transition silo continuously outputs the material to the rear end, thereby ensuring the continuous operation of the entire batching equipment.
[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
