Description

Technical Field

[0001] The present invention relates to the technical field of lithium batteries, and in particular to a lithium battery powder material feeder. Background Art

[0002] A lithium battery is a rechargeable battery that generally uses materials containing lithium as electrodes and relies mainly on the movement of lithium ions between the positive and negative electrodes to work. Common positive electrode materials include lithium cobalt oxide, lithium nickel oxide, lithium manganese oxide, etc. These compounds are usually processed into electrodes in the form of powders. The negative electrode materials usually use graphite or materials with lithium intercalation properties, such as powder raw materials. These powder materials usually need to undergo multiple processes such as mixing, molding, and baking when preparing lithium batteries, and finally form positive and negative electrodes, which constitute the basic components of lithium-ion batteries. Pneumatic conveying is usually used in the powder conveying process of lithium batteries. Pneumatic conveying can avoid direct contact and contamination of powder materials during the conveying process, thereby ensuring the purity of the product. This is especially important for products such as lithium batteries that require high material purity. During the lithium battery powder conveying process, due to the different particle sizes and different settling speeds, powder stratification is prone to occur. Stratification may lead to uneven distribution of active materials inside the battery, thereby reducing the overall performance and stability of the battery. To this end, we propose a lithium battery powder material loader. Summary of the Invention

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example 1: Please refer to Figure 1-12 , the present invention provides a technical solution:

[0031] A lithium battery powder material feeder includes a feeding bin 1, an air pump 2, a feeding pipe 3 and a receiving bin 4, and also includes a separation drum 5. The separation drum 5 is located in the receiving bin 4 and is used to separate lithium battery powder in the airflow.

[0032] The deceleration component 6 is arranged on the feeding tube 3 and is used to adjust the movement speed of smaller powder in the lithium battery powder in the feeding tube 3.

[0033] The advantage of setting up the retarding component 6 is that it can control the large and small particles in the lithium battery powder to arrive at the receiving bin 4 at the same time during the pneumatic transportation process. The advantage of this design is that it helps to mix the materials during the pneumatic transportation process, ensure the uniform distribution between different particles, improve the uniformity of the materials, thereby ensuring the consistency of the positive and negative electrode materials in the battery, further improving the performance and cycle life of the battery, and at the same time reducing the impact of the material's unevenness on the battery's charging and discharging process, and improving the battery's operating stability.

[0034] The separation mechanism 10 is arranged in the receiving bin 4, and the separation drum 5 is arranged on the separation mechanism 10. The separation drum 5 is driven to rotate by the separation mechanism 10 to simultaneously separate the large and small lithium battery powders in the air flow.

[0035] The advantage of setting up the separation mechanism 10 is that it can prevent large particles in the lithium battery powder from settling first and small particles from settling later, resulting in stratification and unevenness, thereby avoiding affecting the overall performance and stability of the battery. At the same time, through simultaneous sedimentation, it can promote the mixing of particles of different sizes in the powder to ensure its uniformity, thereby improving the battery's charge and discharge performance and cycle life, and further improving the consistency and quality stability of the product.

[0036] The deceleration component 6 includes a driving member 7 arranged on the feeding tube 3, which provides power for breaking up the powder in the lithium battery. The driving member 7 is provided with an expansion member 8, which breaks up the lithium battery powder in the feeding tube 3. The feeding tube 3 is provided with a speed reducing member 9, which reduces the movement speed of smaller lithium battery powder.

[0037] The driving member 7 includes a diverter tube 71 arranged on the feeding tube 3, both ends of the diverter tube 71 are connected to the feeding tube 3, a fixed plate 72 is arranged in the diverter tube 71, a driving shaft 73 is rotatably arranged on the fixed plate 72, a driving blade 74 is arranged on the driving shaft 73, a connecting rod 75 is arranged at the end of the driving shaft 73 away from the driving blade 74, and a positioning shaft 76 is arranged on the connecting rod 75.

[0038] When ventilation starts in the feeding pipe 3, the gas is diverted into the diverter pipe 71 at the connection between the diverter pipe 71 and the feeding pipe 3. After entering the diverter pipe 71, the gas pushes the driving blades 74 to rotate, and synchronously drives the driving shaft 73 connected to the driving blades 74 to rotate. When the driving shaft 73 rotates, it drives the connecting rod 75 and the positioning shaft 76 to rotate synchronously.

[0039] The expansion member 8 includes a pneumatic chamber 81 arranged on the shunt tube 71, and the pneumatic chamber 81 is connected to the shunt tube 71. A push rod 82 is rotatably arranged on the positioning shaft 76, and one end of the push rod 82 is extended into the pneumatic chamber 81. The push rod 82 is rotatably arranged on one end away from the positioning shaft 76, and a rotating shaft 83 is rotatably arranged. A connecting plate 84 is provided on the rotating shaft 83. A piston plate 85 is slidably arranged in the pneumatic chamber 81, and the piston plate 85 is connected to the connecting plate 84. An air guide tube 86 is provided on the pneumatic chamber 81, and one end of the air guide tube 86 passes through the feeding tube 3 and is connected to the feeding tube 3. An expansion air bag 87 is provided in the feeding tube 3, and the expansion air bag 87 is connected to the air guide tube 86.

[0040] The advantage of setting up the expansion member 8 is that the contraction and expansion of the expansion airbag 87 can form a changing airflow in the pipeline, thereby promoting the dispersion of lithium battery powder, ensuring that the lithium battery powder is evenly distributed in the air, and avoiding the blockage of the pipeline caused by the adhesion of lithium battery powder. At the same time, it can also allow smaller particles to rise higher, so that smaller particles pass through the separation bin 91 into the separation tube 92 and the speed reduction tube 93, further ensuring that large and small particles continue to reach the receiving bin 4, so that the large and small particles of lithium battery powder in the receiving bin 4 are mixed, and the contact area between the separation bin 91 and the feeding tube 3 is large, which can improve the effect of powder separation. In addition, a small amount of smaller particles follow the large powder particles from the feeding tube 3 into the receiving bin 4 will not cause the separation of powder particle size.

[0041] The rotation of the positioning shaft 76 drives the push rod 82 to move, and simultaneously drives the piston plate 85 connected to the push rod 82 to circulate in the pneumatic chamber 81, so that the gas in the pneumatic chamber 81 enters the expansion airbag 87 through the air guide tube 86, driving the expansion airbag 87 to repeatedly expand and contract, thereby breaking up the lithium battery powder in the feeding tube 3.

[0042] The speed reduction component 9 includes a separation bin 91 arranged on the feeding pipe 3, the separation bin 91 is connected to the feeding pipe 3, a separation pipe 92 is arranged on the separation bin 91, the separation pipe 92 is connected to the separation bin 91, a speed reduction pipe 93 is arranged on the separation pipe 92, the speed reduction pipe 93 is an S-shaped pipe, a confluence pipe 94 is arranged on the speed reduction pipe 93, the confluence pipe 94 is connected to the feeding pipe 3, the confluence pipe 94 is connected to the material receiving bin 4, and one end of the confluence pipe 94 passes through the side wall of the material receiving bin 4 and penetrates into the material receiving bin 4.

[0043] The advantage of setting up the deceleration component 9 is that, through the setting of the S-shaped deceleration tube 93, the movement speed of the smaller lithium battery powder in the pipeline is reduced, thereby preventing the smaller powder from entering the receiving bin 4 too quickly and causing the lithium battery powder to be stratified. The larger powder in the feeding pipe 3 and the smaller powder in the deceleration tube 93 reach the confluence pipe 94 at the same time, and then enter the conveying pipe 111 through the confluence pipe 94.

[0044] The separation mechanism 10 includes a power member 11 arranged in the receiving bin 4, which provides power for the rotation of the separation drum 5. A separation member 12 is provided on the power member 11, which drives the separation drum 5 to rotate. A mixing member 13 is provided on the power member 11, which is used to break up and mix large and small particles in the lithium battery powder.

[0045] The power member 11 includes a delivery pipe 111 provided on the confluence pipe 94, the delivery pipe 111 is rotatably connected to the separation drum 5, the delivery pipe 111 is communicated with the confluence pipe 94, and the delivery pipe 111 is provided on one end of the confluence pipe 94 located in the receiving bin 4, an air outlet pipe 112 is provided on the air outlet pipe 112, a filter plate 113 is provided on the air outlet pipe 112, the air outlet pipe 112 is communicated with the delivery pipe 111 through the filter plate 113, a power plate 114 is provided in the air outlet pipe 112, and the power plate A power shaft 115 is rotatably provided on 114, one end of the power shaft 115 passes through the filter plate 113 and is rotatably connected to the filter plate 113, one end of the power shaft 115 is provided with a power fan blade 116, and a power gear 117 is provided on the power shaft 115. A transmission shaft 118 is rotatably provided on the side wall of the outlet pipe 112, one end of the transmission shaft 118 is provided with a transmission gear 1 119 used in conjunction with the power gear 117, and the end of the transmission shaft 118 away from the transmission gear 1 119 is provided with a transmission gear 2 1110.

[0046] When the gas is discharged from the outlet pipe 112 after gas-solid separation, it drives the power fan blades 116 to rotate, and synchronously drives the power shaft 115 connected to the power fan blades 116 to rotate. When the power shaft 115 rotates, it drives the power gear 117 set thereon to rotate. The rotation of the power gear 117 drives the transmission gear 119 engaged with it to rotate synchronously. When the transmission gear 119 rotates, it drives the transmission shaft 118 to rotate. When the transmission shaft 118 rotates, it drives the transmission gear 2 1110 set thereon to rotate.

[0047] The separating member 12 includes a positioning plate 121 arranged in the material receiving bin 4, the positioning plate 121 is rotatably connected to the separating drum 5, a control shaft 122 is rotatably provided on the positioning plate 121, one end of the control shaft 122 is provided with a control gear 123 that meshes with the transmission gear 2 1110, a rotating gear 124 is provided on the control shaft 122 away from the end of the control gear 123, and a rotating ring gear 125 that meshes with the rotating gear 124 is provided on the separating drum 5, a cleaning plate 126 is provided on the inner wall of the material receiving bin 4, a mounting plate 127 is provided on the cleaning plate 126, a mounting groove 128 is provided on the mounting plate 127, a plurality of extrusion springs 129 are provided in the mounting groove 128, a scraper 1210 is provided on the extrusion spring 129, the scraper 1210 is fitted with the separating drum 5 and slidably connected with the mounting groove 128, and the scraper 1210 is made of rubber.

[0048] The advantage of setting up the separator 12 is that it can quickly separate lithium battery powders of different sizes in the air flow at the same time, avoiding the large particles in the lithium battery powder settling first and the small particles settling later, resulting in stratification and unevenness, thereby avoiding affecting the overall performance and stability of the battery.

[0049] When the transmission gear 2 1110 rotates, it drives the control gear 123 engaged with it to rotate. When the control gear 123 rotates, it drives the control shaft 122 to rotate synchronously. When the control shaft 122 rotates, it drives the rotating gear 124 to rotate. When the rotating gear 124 rotates, it drives the separation drum 5 to rotate through the rotating ring gear 125, centrifuging the powder in the air flow so that the lithium battery powder hits the side wall of the separation drum 5 and finally falls into the receiving bin 4. At the same time, the advantage of the scraper 1210 is that it can scrape the powder on the inner wall of the separation drum 5 to prevent the lithium battery powder from adhering to the inner wall of the separation drum 5. At the same time, the setting of the extrusion spring 129 makes the use of the scraper 1210 more effective.

[0050] The mixing element 13 includes a mounting shaft 131 arranged on the power shaft 115. The mounting shaft 131 is located at one end of the power shaft 115 that passes through the filter plate 113. A plurality of fixing frames 132 are provided on the mounting shaft 131. A telescopic rod 133 is provided in the fixing frame 132. A disturbance plate 134 is provided on the telescopic rod 133. A telescopic spring 135 is sleeved on the telescopic rod 133.

[0051] The advantage of setting up the mixing element 13 is that it can mix the gas carrying lithium battery powder entering the conveying pipe 111, further avoiding stratification and unevenness after particle sedimentation, and at the same time scrape off the lithium battery powder on the disturbance plate 134, so that the powder will not adhere to the disturbance plate 134, avoiding waste of resources.

[0052] As the power shaft 115 rotates, it drives the mounting shaft 131 to rotate. At this time, under the action of centrifugal force, the disturbance plate 134 overcomes the elastic force of the telescopic spring 135 and slides in the fixed frame 132, so that the disturbance plate 134 is unfolded to mix the lithium battery powder in the air flow. When the mounting shaft 131 stops rotating, the disturbance plate 134 will retract back into the fixed frame 132 under the elastic force of the telescopic spring 135. During the retraction process of the disturbance plate 134, the fixed frame 132 will scrape off the lithium battery powder on the disturbance plate 134, so that no powder will adhere to the disturbance plate 134, thereby avoiding waste of resources.

[0053] During use, when ventilation starts in the feeding pipe 3, the gas is diverted into the diverter pipe 71 at the connection between the diverter pipe 71 and the feeding pipe 3. After the gas enters the diverter pipe 71, it drives the driving blades 74 to rotate, and synchronously drives the driving shaft 73 connected to the driving blades 74 to rotate. When the driving shaft 73 rotates, it drives the connecting rod 75 and the positioning shaft 76 to rotate synchronously.

[0054] The rotation of the positioning shaft 76 drives the push rod 82 to move, and simultaneously drives the piston plate 85 connected to the push rod 82 to circulate in the pneumatic chamber 81, so that the gas in the pneumatic chamber 81 enters the expansion airbag 87 through the air guide tube 86, driving the expansion airbag 87 to repeatedly expand and contract, breaking up the lithium battery powder in the feeding tube 3. At the same time, smaller particles enter the separation tube 92 and the speed reduction tube 93 through the separation chamber 91. The larger powder in the feeding tube 3 and the smaller powder in the speed reduction tube 93 reach the confluence tube 94, and then enter the conveying tube 111 through the confluence tube 94.

[0055] When the gas is discharged from the exhaust pipe 112, it drives the power fan blades 116 to rotate, and synchronously drives the power shaft 115 connected to the power fan blades 116 to rotate. When the power shaft 115 rotates, it drives the power gear 117 set thereon to rotate. The rotation of the power gear 117 drives the transmission gear 1 119 engaged with it to rotate synchronously. When the transmission gear 1 119 rotates, it drives the transmission shaft 118 to rotate. When the transmission shaft 118 rotates, it drives the transmission gear 2 1110 set thereon to rotate.

[0056] When the transmission gear 2 1110 rotates, it drives the control gear 123 engaged with it to rotate. When the control gear 123 rotates, it drives the control shaft 122 to rotate synchronously. When the control shaft 122 rotates, it drives the rotating gear 124 to rotate. When the rotating gear 124 rotates, it drives the separation drum 5 to rotate through the rotating ring gear 125, centrifuging the powder in the air flow, so that the lithium battery powder hits the side wall of the separation drum 5 and finally falls into the receiving bin 4. At the same time, the advantage of setting the scraper 1210 is that it can scrape the powder on the inner wall of the separation drum 5.

[0057] As the power shaft 115 rotates, it drives the mounting shaft 131 to rotate. At this time, under the action of centrifugal force, the disturbance plate 134 overcomes the elastic force of the telescopic spring 135 and slides in the fixed frame 132, so that the disturbance plate 134 is unfolded to mix the lithium battery powder in the air flow. When the mounting shaft 131 stops rotating, the disturbance plate 134 will retract back into the fixed frame 132 under the elastic force of the telescopic spring 135. During the retraction process of the disturbance plate 134, the fixed frame 132 will scrape off the lithium battery powder on the disturbance plate 134, so that no powder will adhere to the disturbance plate 134, thereby avoiding waste of resources.

[0058] Example 2: Please refer to Figure 13 , the present invention provides a technical solution:

[0059] Different from Example 1, the scraper 1210 is made of polyurethane. The polyurethane scraper 1210 has better wear resistance and can effectively increase the service life of the scraper 1210.
