Abstract
Description
Technical Field
[0001] The invention relates to a ternary precursor preparation device, in particular to a ternary precursor preparation standby mixed solution batching device. Background Art
[0002] The ternary precursor material is nickel cobalt manganese hydroxide, which is made from a sulfuric acid mixed solution of nickel sulfate, cobalt sulfate, manganese sulfate and solvent, and then auxiliary agents (ammonia solution, alkaline solution) are added for stirring and mixing. The stirred solution is then pumped into a concentrator for concentration. When the concentrator reaches the specified liquid level, the filter liquid valve is opened to discharge the clear liquid, and finally the overflow valve is opened to discharge the material. The discharged material becomes a qualified product after washing, drying, screening and packaging.
[0003] During the batching process of the sulfuric acid mixed solution, the flow meter is used to pump the liquid raw materials in the raw material kettle into the required batching equipment, and then the feed port cover is opened, the sulfate packaging bag is cut open with a utility knife, and the sulfate is put into the batching kettle and stirred at a certain temperature and liquid level. However, during the sulfate feeding process, workers found that part of the sulfate in the bag was agglomerated, which would affect the overall feeding. Even after it was manually broken up with a wooden hammer, the agglomerated particles were still much larger than normal particles, so it was necessary to extend the normal dissolution batching time, otherwise the concentration of the sulfuric acid mixed solution would easily fail to meet the requirements for preparing the ternary precursor. Summary of the invention

[0008] A side flow guide structure, wherein a plurality of stirring blades are arranged on the stirring rod of the stirring structure, and the side flow guide structure comprises two guide arc buckets arranged on the inner top of the tank body, wherein the guide arc buckets are located below the projection position of the diverter plate, and there is a material stirring structure fixed to the tank body on both sides of the guide arc buckets, and the ends of the guide arc buckets extend to the lateral direction of the stirring blades at the top of the stirring rod, and when the particles fall to the guide arc buckets through the diverter plate, the guide arc buckets are compressed to squeeze the material stirring structure, and the material stirring structure vibrates the guide arc buckets and transports the particles on the guide arc buckets to the stirring blades at the top of the stirring rod.
[0009] As a further improvement, the diameter of the holes on the guide baffle is three times the required particle size, and the top of the guide baffle is rounded.
[0010] As a further improvement, the initial position of the diverter plate is flush with the bottom end of the guide baffle, and the diameter of the through hole on the diverter plate is twice the required particle size.
[0011] As a further improvement, the rebound structure includes two rows of rebound frames arranged in the lateral installation area, the top of the rebound frame is fixedly connected to a bonding plate, the bonding plate is locked under the diverter plate, and an outer sealing canopy is glued to one side of the top surface of the diverter plate close to the guide baffle.
[0012] As a further improvement, the rebound frame includes a guide cylinder arranged on the inner wall of the lateral installation area, a correction cylinder is arranged above the guide cylinder, and a rebound spring is arranged on the inner side of the guide cylinder and the correction cylinder, and the rebound spring is locked to the bottom of the bonding plate.
[0013] As a further improvement, the crushing structure includes a driving motor arranged at the upper inner half of the lateral mounting area, and a pressing plate is arranged at the bottom of all the driving motors.
[0014] As a further improvement, a plurality of rolling pins are welded to the bottom of the rolled plate.
[0015] As a further improvement, the material lifting structure includes an arc tube arranged on the top of the tank body, and a plurality of hanging springs are cantilevered at the bottom of the arc tube, and the bottom of the hanging springs is fixedly connected to the guide arc bucket.
[0016] As a further improvement, a clamping gap is provided on the top surface of the sulfate feed hopper, and a clamping piece is provided on the side of the clamping gap away from the sulfate feed hopper feeding. When the cloth bag filled with particles is inserted into the clamping gap, one end of the cloth bag is fixed by the clamping piece.
[0017] The beneficial effects of the present invention are:
[0018] In some existing mixed solution batching tanks, most of them directly pour a whole bag of sulfate particles into the tank through the opening on the tank. If agglomerated particles are found during the pouring process, they will be crushed with a mallet or by hand. Although this can solve the problem of agglomeration, on the one hand, the feeding speed is too fast and it is difficult for workers to react. On the other hand, workers are prone to bring in some impurities when intervening, which affects the purity of the solution. Therefore, the present invention provides a graded feeding mechanism and a guide baffle at the position of the sulfate feed hopper. Sulfate particles of conventional particle size can directly enter the tank through the guide baffle and be mixed and stirred with the solution. Agglomerates due to improper storage or quality problems of the product itself will slide down along the guide baffle to the position of the diverter plate, and are continuously pressed by the crushing structure above the diverter plate until the particles meet the requirements and fall from the position of the diverter plate. Therefore, while not blocking the falling of conventional particles, the whole agglomerated particles can also enter the tank more promptly, avoiding some particles from being stuck at the feeding position and unable to fall, thereby affecting subsequent feeding.
[0019] When setting the guide baffle and the diverter plate, the retention time of the particles needs to be taken into consideration, so as to ensure that the particles can be quickly and smoothly distinguished and transported into the tank. Therefore, in this case, the diameter of the holes on the guide baffle is set to three times the required particle size, and the diameter of the through holes on the diverter plate is set to twice the required particle size, so that both rapid material discharge and material separation can be achieved. Moreover, if the through holes on the diverter plate are set too small, it is easy to cause particle accumulation on the diverter plate, affecting normal material discharge. Therefore, it is not advisable to set the through holes on the diverter plate too small.
[0020] When the particles on the diverter plate are pressed by the crushing structure, if the diverter plate is installed in a completely fixed manner, the mobility of the particles is poor, and the clumps that intersect the crushing structure cannot be crushed. Therefore, in this case, the diverter plate is fixed on the rebound frame through the provision of a rebound structure, and the particles on the diverter plate can have a certain jumping phenomenon when shaken by the extension and contraction of the rebound frame, and their position can be changed, thereby improving the pressing effect. In order to avoid leakage due to a gap between the movable diverter plate and the guide baffle, the present invention also arranges an external sealing canopy on the side of the diverter plate to seal the material, thereby completely blocking the particles and preventing particles that do not meet the required particle size from directly entering the tank body.
[0021] In order to improve the crushing effect of the crushing structure on the agglomerated particles, the present invention provides crushing nails on the crushing plate at the bottom of the crushing structure. The crushing nails can crush the agglomerated particles faster, and the overall crushing effect is better when combined with the diverter plate that continuously moves up and down.
[0022] Although the agglomerated particles are processed by the diverter plate and the crushing structure, due to the continuous feeding, the number of times the crushing structure can be reciprocated is limited, and it is difficult to crush the particles into the required particle size in a short time. Therefore, the present invention sets a side flow guide structure at the lower end of the diverter plate. The particles falling through the guide baffle can directly fall into the solution, while the particles falling through the diverter plate will fall into the side flow guide structure. The falling particles will form pressure on the guide arc bucket, thereby causing the guide arc bucket movably arranged on the material shaking structure to start shaking up and down, continuously transporting the particles downward, and they can be separated during the transportation process. The end of the guide arc bucket is opposite to the stirring blade at the top of the stirring rod, and the transported particles will be directly cut, so that the particles that originally did not meet the requirements can be better mixed and reacted with the solution, and the prepared liquid meets the requirements for the preparation of the ternary precursor.

When the particles are poured onto the guide baffle 51, the particles with a diameter smaller than the hole are crushed. The particles directly enter the tank body 10 through the guide baffle 51, and the particles with a particle size larger than the hole fall to the top of the diverter plate 52 through the guide baffle 51. The particles falling on the diverter plate 52 are crushed by the crushing structure 54, so that the particles can enter the tank body 10 through the diverter plate 52; the side flow guide structure 60, the stirring rod of the stirring structure 30 is provided with a plurality of stirring blades 31, the side flow guide structure 60 includes two guide arc buckets 61 arranged on the top of the inner side of the tank body 10, the guide arc bucket 61 Located below the projection position of the diverter plate 52, there are a material-lifting structure 62 fixed to the tank body 10 on both sides of the guide arc bucket 61, and the end of the guide arc bucket 61 extends to the side of the stirring blade 31 at the top of the stirring rod. When the particles fall into the guide arc bucket 61 through the diverter plate 52, the guide arc bucket 61 is compressed and squeezes the material-lifting structure 62. The material-lifting structure 62 vibrates the guide arc bucket 61 and transports the particles on the guide arc bucket 61 to the stirring blade 31 at the top of the stirring rod.
[0037] Sulfate solution is one of the important raw materials for the ternary precursor. In the process of preparing the sulfate solution, it is necessary to add a variety of solids such as manganese sulfate, nickel sulfate, cobalt sulfate and other auxiliary liquids. In this embodiment, the liquid raw material is added through the liquid feed pipe 20, and the solid raw material is added through the sulfate feed hopper 40.
[0038] In the process of adding raw materials, liquid raw materials are added first, then solid raw materials are added, and finally stirring is performed. Samples are taken after stirring for 2 hours when the feed is more than 200 kg, and samples are taken after stirring for 1 hour when the feed is less than 200 kg. Materials that are less than one bag must be accurately weighed using an electronic scale.
[0039] The length of the top stirring blade 31 is shorter than the length of the lower stirring blade 31 , so that it can better adapt to the side flow guide structure 60 .
[0040] In the process of loading a whole bag of sulfate particles, the whole bag of particles is moved to the position of the tank body 10 by moving a vehicle within the factory area, and then fixed and unloaded with manual assistance. Workers are required to hold the bag body, which is difficult to do. Therefore, in this embodiment, a clamping gap 43 is provided on the top surface of the sulfate feed hopper 40, and a clamping piece 44 is provided on the side of the clamping gap 43 away from the feeding side of the sulfate feed hopper 40. When the cloth bag filled with particles is embedded in the clamping gap 43, one end of the cloth bag is fixed by the clamping piece 44, so that a certain amount of auxiliary support can be provided during the stage of opening the bag with a utility knife.
[0041] In some existing mixed solution batching tanks, most of them directly pour the whole bag of sulfate particles into the tank through the opening on the tank. If agglomerated particles are found during the pouring process, they will be crushed with a mallet or by hand. Although this can solve the problem of agglomeration, on the one hand, the material feeding speed is too fast, and it is difficult for workers to react. On the other hand, it is easy for workers to bring in some impurities when they intervene, affecting the purity of the solution. Therefore, this embodiment provides a graded material feeding mechanism 50, and a guide baffle 51 is provided at the position of the sulfate feed hopper 40, so that the sulfate particles of conventional particle size can be The particles can directly enter the tank body 10 through the guide baffle 51 and be mixed and stirred with the solution. The particles that are agglomerated due to improper storage or quality problems of the product itself will slide down the guide baffle 51 to the position of the diverter plate 52, and are continuously pressed by the crushing structure 54 arranged above the diverter plate 52 until the particles meet the requirements and fall from the position of the diverter plate 52. In this way, while not blocking the falling of conventional particles, the entire mass of particles can also enter the tank body 10 in a relatively timely manner, thereby preventing some particles from being stuck at the discharge position and unable to fall, thereby affecting subsequent discharge.
[0042] When setting the guide baffle 51 and the diverter plate 52, the retention time of the particles needs to be taken into consideration, so as to ensure that the particles can be quickly and smoothly distinguished and transported to the tank body 10. Therefore, the diameter of the holes on the guide baffle 51 of this embodiment is three times the required particle size, and the top of the guide baffle 51 is chamfered. First, the diameter of the holes on the guide baffle 51 is set to three times the required particle size. Secondly, the initial position of the diverter plate 52 is flush with the bottom end of the guide baffle 51, and the diameter of the through holes on the diverter plate 52 is twice the required particle size. The diameter of the through holes on the diverter plate 52 is twice the required particle size, so that fast material discharge and material separation can be completed. If the through holes on the diverter plate 52 are set too small, it is easy to cause particle accumulation on the diverter plate 52, affecting normal material discharge. Therefore, it is not advisable to set the through holes on the diverter plate 52 too small.
[0043] When the particles on the diverter plate 52 are pressed by the crushing structure 54, if the diverter plate 52 is installed in a completely fixed manner, the mobility of the particles is poor, and the massed objects crossing the crushing structure 54 cannot be crushed. Therefore, the rebound structure 53 of this embodiment includes two rows of rebound frames 531 arranged in the lateral installation area 42, and the top of the rebound frame 531 is fixedly connected with a bonding plate 532, and the bonding plate 532 is locked under the diverter plate 52. The diverter plate 52 is fixed on the rebound frame 531 through the provided rebound structure 53. The particles on the diverter plate 52 can jump to a certain extent when being shaken by the extension and retraction of the rebound frame 531, and their position can change, thereby improving the effect of the pressing. In order to avoid a gap between the movable diverter plate 52 and the guide baffle 51, thereby causing material leakage, preferably, an outer sealing cap 533 is glued to the side of the top surface of the diverter plate 52 close to the guide baffle 51, and the outer sealing cap 533 is set on the side of the diverter plate 52 to seal the material, thereby completely blocking the particles and preventing particles that do not meet the required particle size from directly entering the tank body 10.
[0044] In the specific crushing stage, the crushing structure 54 includes a driving motor 541 arranged on the upper inner half of the lateral mounting area 42, and a pressing plate 542 is arranged at the bottom of all the driving motors 541. The same pressing plate 542 is driven by a plurality of driving motors 541 to press the agglomerated particles. In order to improve the pressing effect of the crushing structure 54 on the agglomerated particles, the present embodiment provides pressing nails on the pressing plate 542 at the bottom of the crushing structure 54. The pressing nails can crush the agglomerated particles faster, and the overall crushing effect is better when combined with the diverter plate 52 that continuously moves up and down. Even if there is moisture in the particles, a better crushing and separation effect can be achieved.
[0045] Although the agglomerated particles are processed by the diverter plate 52 and the crushing structure 54, due to the continuous feeding, the number of times the crushing structure 54 can be reciprocated is limited, and it is difficult to crush the particles into the required particle size in a short time. Therefore, the present invention sets a side flow guide structure 60 at the lower end of the diverter plate 52. The particles falling through the guide baffle 51 can directly fall into the solution, while the particles falling through the diverter plate 52 will fall into the side flow guide structure 60. The falling particles will form pressure on the guide arc bucket 61, thereby causing the guide arc bucket 61 movably arranged on the material-lifting structure 62 to start shaking up and down, continuously transporting the particles downward, and they can be separated during the transportation process. The end of the guide arc bucket 61 is opposite to the stirring blade at the top of the stirring rod, and the transported particles will be directly cut, so that the particles that originally did not meet the requirements can be better mixed and reacted with the solution, and the prepared liquid meets the requirements for the preparation of the ternary precursor.
[0046] Among them, the lifting material structure 62 includes an arc tube 621 arranged on the top of the tank body 10, and a plurality of hanging springs 622 are cantilevered at the bottom of the arc tube 621. The bottom of the hanging spring 622 is fixedly connected to the guide arc bucket 61. The arc tube 621 can adapt to the arc-shaped inner surface of the tank body 10, and it can serve as a hanging surface of the hanging spring 622 to fix the spring. In addition, the hanging spring 622 in this embodiment needs to be set thinner to ensure its sensitivity.
[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have 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.
