[0037] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0038] This utility model embodiment provides, as follows: Figure 1 As shown, a covering device 100 includes a bucket-shaped covering tarpaulin 110 and a lifting control mechanism 120;

[0039] The bucket-shaped tarpaulin 110 has an upper opening 111 and a lower opening 112. The upper opening 111 is provided with a first connector 113 for connecting the bucket-shaped tarpaulin 110 to the discharge port of the centrifugal device; the lower opening 112 is provided with a second connector 114 for connecting to the feed port of the mobile material cart 200.

[0040] The lifting control mechanism 120 is connected to the bucket-shaped tarpaulin 110 to control the up and down movement of the bucket-shaped tarpaulin 110.

[0041] The ternary precursor feeding system provided in this embodiment of the utility model includes a mobile material cart 200 and (such as...) Figure 2 (As shown) the above-mentioned covering device 100;

[0042] The size of the feed inlet of the mobile material cart 200 corresponds to the size of the lower opening 112 of the bucket-shaped tarpaulin 110. When feeding, the bucket-shaped tarpaulin 110 moves down under the action of the lifting control mechanism 120, and then the bucket-shaped tarpaulin 110 is fitted onto the feed inlet of the mobile material cart 200 through the lower opening 112.

[0043] The covering device 100 provided in this embodiment of the utility model is used by employees who place the bucket-shaped covering tarpaulin 110 over the centrifuge discharge port through the upper opening 111. The first connecting piece 113 is fixed to the bottom flange of the centrifuge discharge port. Then, the moving material cart 200 is pushed to the centrifuge discharge port, and the bucket-shaped covering tarpaulin 110 is pulled down until it covers the inlet of the moving material cart 200. The second connecting piece 114 on the bucket-shaped covering tarpaulin 110 is connected to the moving material cart 200. Then, the material is discharged. After the centrifuge discharge is completed, the connection between the second connecting piece 114 and the moving material cart 200 is separated. Then, the bucket-shaped covering tarpaulin 110 is moved up by operating the lifting control mechanism 120. Finally, the bucket-shaped covering tarpaulin 110 is retracted to the bottom of the centrifuge.

[0044] The covering device 100 provided by this utility model can cover the nickel-cobalt-manganese ternary battery material powder when it is fed into the mobile material cart 200, preventing the material from spilling or scattering due to its low moisture content. This device can greatly reduce the occupational disease risk for employees and avoid occupational exposure and material spillage problems caused by employees feeding materials into the centrifuge.

[0045] Optionally, depending on the size of the centrifuge discharge port and the feed port of the mobile material cart 200, the hopper-shaped covering tarpaulin 110 is typically an inverted funnel shape, with the diameter of the upper feed port larger than the diameter of the lower feed port. For example, when fully unfolded, the diameter of the lower opening 112 is 1000~1200mm, and the diameter of the upper opening 111 is 400~600mm.

[0046] Optionally, the first connector 113 consists of a plurality of binding ropes 113a evenly arranged along the edge of the bucket-shaped tarpaulin 110 corresponding to the upper opening 111.

[0047] The bucket-shaped tarpaulin 110 is tied to the bottom flange of the centrifuge discharge port by multiple ropes 113a, which is simple and convenient to operate.

[0048] Optionally, such as Figures 1 to 4 As shown, the second connector 114 includes a support ring 115 and a plurality of buckles 114a evenly distributed on the inner side of the support ring 115. The support ring 115 is located on the inner side of the corresponding lower opening 112 of the bucket-shaped tarpaulin 110.

[0049] The top outer wall of the mobile material cart 200 is provided with a fixing ring 211. The fixing ring 211 has notches 212 that correspond to the number of buckles 114a and are evenly distributed. The width of the notches 212 is not less than the width of the buckles 114a.

[0050] During material unloading, align the buckle 114a with the notch 212, move the support ring 115 downwards so that the buckle 114a passes through the corresponding notch 212, and then rotate the support ring 115 so that all the buckles 114a are below the fixing ring 211, thus connecting the bucket-shaped covering tarpaulin 110 to the mobile material cart 200. After unloading, rotate the support ring 115 again so that the buckles 114a are aligned with the notch 212, and then move the support ring 115 upwards to disengage the buckles 114a from the notch 212, thus separating the bucket-shaped covering tarpaulin 110 from the mobile material cart 200.

[0051] It should be noted that the above-mentioned arrangement of the buckle 114a and notch 212 is not unique. In other embodiments of this utility model, the buckle 114a can be replaced with a latch, lock, snap, snap, spring buckle, or quick buckle, as long as it can be connected and fixed with the fixing ring 211 on the mobile material cart 200.

[0052] Optionally, the retaining ring 211 on the mobile material cart 200 is made of PPH, PPR, or PE material, and its width is, for example, 20mm. Optionally, the buckle 114a is made of PPH, PPR, or PE material.

[0053] Optionally, the number of clips 114a is 2 to 4, the number of notches 212 is the same, the width of clips 114a is 10 to 40 mm, and the width of notches 212 is slightly larger than that of clips 114a, for example, 50 mm.

[0054] Optionally, the lifting control mechanism 120 includes at least two lifting sets, each lifting set including a first pulley 121, a traction rope 123 and at least one counterweight 124;

[0055] One end of each traction rope 123 is connected to the bucket-shaped tarpaulin 110, and the first pulley 121 is fixed above the connection between the bucket-shaped tarpaulin 110 and the traction rope 123. The other end of the traction rope 123 extends through the first pulley 121 and is detachably connected to the counterweight 124.

[0056] Workers can control the upward movement of the bucket-shaped canopy tarpaulin 110 by connecting counterweights 124 to the traction rope 123 or increasing the number of counterweights 124, and control the downward movement of the bucket-shaped canopy tarpaulin 110 by removing or decreasing the number of counterweights 124. The pulleys, traction rope 123, and counterweights 124 make it easy for workers to operate the bucket-shaped canopy and move it up and down. Moreover, this structure is purely mechanical, requires no electricity, and is easy to maintain and repair.

[0057] Furthermore, the lifting assembly also includes a second pulley 122, located directly above the connection point between the bucket-shaped tarpaulin 110 and the traction rope 123. A first pulley 121 is positioned above the connection point between the bucket-shaped tarpaulin 110 and the traction rope 123, spaced apart from the second pulley 122. The other end of the traction rope 123 passes sequentially through the second pulley 122 and the first pulley 121 before extending downwards to be detachably connected to the counterweight 124. The two pulleys allow for better control of the lifting and lowering of the bucket-shaped tarpaulin 110.

[0058] Furthermore, such as Figure 1 and Figure 5 As shown, each traction rope 123 includes a main rope segment 123a and multiple branch rope segments 123b connected to the main rope segment 123a. All branch rope segments 123b of the two lifting sets are connected to the bucket-shaped tarpaulin 110 and are evenly distributed along the lower opening 112. The two lifting sets are symmetrically arranged to control the lifting of the bucket-shaped tarpaulin 110 more effectively and stably.

[0059] Furthermore, the branch rope segment 123b is connected to the support ring 115 to facilitate more stable control of the raising and lowering of the bucket-shaped tarpaulin 110.

[0060] Furthermore, the length of the traction rope 123 is, for example, 2000~2500mm.

[0061] Furthermore, the traction rope 123 can be made of PTFE (polytetrafluoroethylene) coated traction rope 123, fluororubber (FKM) traction rope 123, silicone coated glass fiber traction rope 123, stainless steel wire rope (with protective layer), aramid (Kevlar) traction rope 123 (with corrosion resistant coating), etc.

[0062] Furthermore, the funnel-shaped tarpaulin 110 can be made of silicone-coated fiberglass cloth, PTFE (polytetrafluoroethylene) coated tarpaulin, neoprene rubber (CR) coated tarpaulin, PVC (polyvinyl chloride) coated tarpaulin, or fluororubber (FKM) coated tarpaulin, etc.

[0063] Furthermore, the material of the counterweight 124 can be stainless steel, Hastelloy, titanium alloy, ceramic (alumina / silicon carbide), lead-coated, barite concrete, tungsten alloy, etc.

[0064] In summary, the covering device 100 and the ternary precursor feeding system provided by this utility model can cover the nickel-cobalt-manganese ternary battery material powder when it is fed into the mobile material cart 200, preventing material spillage and scattering due to low moisture content. This device can significantly reduce the occupational disease risk for employees and avoid occupational exposure and material spillage problems caused by employees feeding materials into the centrifuge.

[0065] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
