[0002] There are many types of positive electrode materials for lithium batteries, and they have the characteristics of good fluidity and low bulk density. These characteristics make it easy for positive electrode materials to generate dust during transportation, and require the conveying equipment to have high adaptability and flexibility. In the traditional transportation process of positive electrode materials for lithium batteries, mechanical conveying methods such as belt conveying and spiral conveying are mainly used. However, these methods often have problems such as low conveying efficiency, easy to generate dust pollution, and high equipment maintenance costs. The airflow conveying equipment for the production of positive electrode materials for lithium batteries is an efficient and environmentally friendly conveying system. It uses the kinetic energy of the airflow to make granular materials (such as positive electrode materials for lithium batteries) suspended, bolted or continuous in the form of sand dunes, and is transported along the pipeline with the airflow. It has the advantages of good sealing performance, high conveying efficiency, and strong adaptability.

[0028] Embodiment 1:

[0029] See also Figure 1-Figure 7As shown, an air flow conveying device for producing positive electrode materials for lithium batteries comprises a base 1; an air compressor body 3 is fixedly connected to the top of the outer wall of the base 1 through a support column 2; a delivery pipe 4 is provided at the output end of the air compressor body 3; a feed shell 5 is fixedly connected to the top of the outer wall of the delivery pipe 4, and the feed shell 5 is communicated with the delivery pipe 4; a separator is provided at the bottom end of the outer wall of the delivery pipe 4, and the separator is communicated with the delivery pipe 4; a motor 6 is fixedly connected to one side of the outer wall of the support column 2; a rotating shaft 7 is provided at the output end of the motor 6; a fixed plate 8 is fixedly connected to the inner side wall of the delivery pipe 4; a rotating rod 9 is rotatably connected to one side of the outer wall of the fixed plate 8; a connecting plate 10 is fixedly connected to one end of the outer wall of the rotating rod 9; a pair of cleaning plates 11 are fixedly connected to one side of the outer wall of the connecting plate 10, and the outer side walls of the pair of cleaning plates 11 are in contact with the inner side wall of the delivery pipe 4; the outer side walls of the rotating rod 9 and the rotating shaft 7 are connected to the inner side wall of the delivery pipe 4; The side walls are fixedly connected with a transmission wheel 12, and a pair of transmission wheels 12 are connected by a transmission belt 13; the transmission belt 13 passes through the conveying pipe 4, and the transmission belt 13 is sealed and connected to the conveying pipe 4. By putting the material from the feed shell 5, when the material enters the conveying pipe 4 through the feed shell 5, the motor 6 drives the rotating shaft 7 to rotate, so that the rotating shaft 7 drives the rotating rod 9 to rotate through the transmission wheel 12 and the transmission belt 13, so that the rotation of the rotating rod 9 drives the connecting plate 10 and the cleaning plate 11 to rotate, so that the cleaning plate 11 cleans the inner wall of the conveying pipe 4, so that the material is not easy to accumulate or adhere to the conveying pipe 4, thereby ensuring that the conveying efficiency of the conveying pipe 4 is not easily reduced, and avoiding the resistance caused by material accumulation or adhesion, reducing energy consumption, and reducing the probability of accumulated or adhered materials falling off and mixing into the material being conveyed.

[0030] A pair of rotating rods 22 are rotatably connected to one side of the outer wall of the connecting plate 10; a third gear 23 is fixedly connected to the outer wall of the rotating rod 22; an annular rack 24 is fixedly connected to the inner wall of the conveying pipe 4; the pair of third gears 23 are meshed with the annular rack 24; a group of fan blades 25 are fixedly connected to the outer wall of the pair of rotating rods 22. When the connecting plate 10 rotates, the connecting plate 10 drives the rotating rod 22 and the third gear 23 on the rotating rod 22 to rotate. Because the pair of third gears 23 are meshed with the annular rack 24 mesh with each other, so that when the third gear 23 rotates, the annular rack 1 24 rotates, so that the third gear 23 drives the rotating rod 1 22 to rotate, and the rotating rod 1 22 drives the fan blade 25 to rotate, so that the blowing of the fan blade 25 enhances the transportation of materials, and the high-pressure airflow generated by the air compressor body 3 will also blow the fan blade 25, so that the fan blade 25 rotates. When the fan blade 25 rotates, it will also drive the rotating rod 1 22, the connecting plate 10, and the rotating rod 9 to rotate, thereby reducing the energy consumption of the motor 6, so that each structure complements each other.

[0031] The separation member includes a cylinder 14; the bottom end of the outer wall of the cylinder 14 is rotatably connected to the top end of the outer wall of the base 1; the top end of the outer wall of the cylinder 14 is fixedly connected to a separation shell 15; the top end of the outer wall of the separation shell 15 is sealed and rotatably connected to a cover plate 16, and the top end of the outer wall of the cover plate 16 is fixedly connected to the bottom end of the outer wall of the conveying pipe 4, and the conveying pipe 4 is connected to the separation shell 15 through the cover plate 16; the bottom end of the outer wall of the separation shell 15 is fixedly connected to a group of feed pipes 17, and the group of feed pipes 17 are all connected to the separation shell 15 , an electric control valve is provided in the discharge shell; an airflow pipe 18 is fixedly connected to the top of the outer wall of the cover plate 16, and the airflow pipe 18 is connected to the cover plate 16; a filter screen 19 is fixedly connected to the top of the outer wall of the airflow pipe 18; a first bevel gear 20 is fixedly connected to the outer wall of the cylinder 14; a second bevel gear 21 is fixedly connected to one end of the outer wall of the rotating shaft 7, and the first bevel gear 20 and the second bevel gear 21 are meshed with each other. When the material in the conveying pipe 4 enters the separation shell 15 through the high-pressure airflow generated by the air compressor body 3, the material in the conveying pipe 4 enters the separation shell 15 through the high-pressure airflow generated by the air compressor body 3. The rotation of the rotating shaft 7 drives the second bevel gear 21 to rotate, and the second bevel gear 21 meshes with the first bevel gear 20, so that the second bevel gear 21 drives the cylinder 14 to rotate through the first bevel gear 20, and the cylinder 14 drives the separation shell 15 to rotate, so that centrifugal force is generated when the material enters the separation shell 15. At this time, the air in the material moves toward the center of the separation shell 15, and the material moves toward the inner wall of the separation shell 15 under the action of centrifugal force. The air will flow to the outside through the airflow pipe 18, and the top of the outer wall of the airflow pipe 18 is fixedly connected with a filter screen 19, so that a small part of the material flowing with the air is blocked by the filter screen 19, thereby avoiding the material from polluting the external environment, and when the filter screen 19 cannot block the material, a dust collector can be added to the filter screen 19 to further clean the material, so that the device can separate the air and the material while avoiding the impact of the material on the environment. When the material is separated, the material is discharged through the discharge pipe 17.

[0032] The opposite sides of the outer wall of the connecting plate 10 are rotatably connected to the second rotating rod 26 through the first square plate; the outer wall ends of the pair of rotating rods 26 are fixedly connected to the fourth gear 27, and the pair of fourth gears 27 are meshed with the annular rack 1 24; the outer wall of the second rotating rod 26 is fixedly connected to a group of stirring plates 28, and the stirring plates 28 match the inner wall of the conveying pipe 4; the pair of cleaning plates 11 and the two groups of stirring plates 28 are distributed in a cross shape. When the connecting plate 10 rotates, the connecting plate 10 drives the second rotating rod 26 to rotate through the first square plate, so that the rotating rod 26 is rotated. Rod 26 drives the fourth gear 27 to rotate. Since a pair of fourth gears 27 are meshed with the annular rack 1 24, the fourth gear 27 rotates through the annular rack 1 24, so that the fourth gear 27 drives the rotating rod 26 to rotate, and the rotating rod 26 drives the stirring plate 28 to rotate. When the material is conveyed, the stirring plate 28 stirs the material to avoid adhesion and condensation, thereby affecting the conveying efficiency or effect, and the stirring plate 28 breaks up the material, so that the conveying efficiency of the material is further improved.

[0033] A circular rod 29 is rotatably connected to one side of the inner wall of the feed shell 5, and one end of the outer wall of the circular rod 29 passes through the feed shell 5; a group of quantitative unloading plates 30 are fixedly connected to the outer side wall of one end of the circular rod 29 located in the feed shell 5; a transmission wheel 2 31 is fixedly connected to one end of the outer wall of the circular rod 29 and the outer side wall of the rotating rod 9, and a pair of transmission wheels are connected by a transmission belt 2 32; the transmission belt 2 32 passes through the conveying pipe 4, and the transmission belt 2 32 is sealed and connected to the conveying pipe 4. When the rotating rod 9 rotates, the rotating rod 9 drives the circular rod 29 to rotate through the transmission wheel 2 31 and the transmission belt 2 32, so that the circular rod 29 drives the quantitative unloading plate 30 to rotate, so that the material is quantitatively unloaded, thereby accurately controlling the feeding operation of the material, making the feeding more accurate, and making it difficult for the material to enter the conveying pipe 4 at one time, causing the conveying pipe 4 to be blocked.

[0034] The bottom end of the outer wall of the cover plate 16 is fixedly connected to an annular rack 38; the bottom end of the inner wall of the separation shell 15 is rotatably connected to a reciprocating rod 39; the outer wall of the reciprocating rod 39 is provided with an annular plate 40, and the outer wall of the annular plate 40 is in contact with the inner wall of the separation shell 15; the top end of the outer wall of the reciprocating rod 39 is fixedly connected to a seventh gear 41, and the seventh gear 41 is meshed with the annular rack 38. When the separation shell 15 rotates, the separation shell 15 drives the reciprocating rod 39 and the reciprocating rod 39 to rotate. The seventh gear 41 on 9 rotates. Since the seventh gear 41 is meshed with the annular rack 2 38, the seventh gear 41 rotates through the annular rack 2 38, so that the seventh gear 41 drives the reciprocating rod 39 to rotate, and the reciprocating rod 39 drives the annular plate 40 to reciprocate. When the material moves to the inner wall of the separation shell 15 under the action of centrifugal force, the reciprocating motion of the annular plate 40 will scrape the material, so that the material moves to the lower material pipe 17, thereby accelerating the material discharge efficiency.

[0035] A fifth bevel gear 33 is fixedly connected to the outer wall of the circular rod 29; a rotating rod 5 34 is rotatably connected to one side of the outer wall of the feed shell 5 through a second square plate; a sixth bevel gear 35 is fixedly connected to the bottom end of the outer wall of the rotating rod 5 34, and the sixth bevel gear 35 and the fifth bevel gear 33 are meshed with each other; a group of soft rods 36 are fixedly connected to the outer wall of the rotating rod 5 34; a knocking ball 37 is fixedly connected to one end of the outer wall of the soft rod 36, and the knocking ball 37 matches the feed shell 5. When the circular rod 29 rotates, the circular rod 29 drives the fifth bevel gear 33 to rotate, so that the fifth bevel gear 33 drives the rotating rod 5 34 to rotate through the sixth bevel gear 35, so that the rotating rod 5 34 drives the soft rod 36 and the knocking ball 37 to rotate, so that the knocking ball 37 hits the feed shell 5, so that the material in the feed shell 5 vibrates, thereby further facilitating the unloading of the material, and the vibration force disperses the material, so that the material is not easy to adhere or condense.

[0036] A group of slide plates 42 are fixedly connected to the bottom end of the outer wall of the annular rack 38; a baffle plate 43 is slidably connected to one side of the outer wall of a group of slide plates 42, and a group of baffle plates 43 are respectively matched with a group of discharge pipes 17; the top end of the outer wall of a group of baffle plates 43 is slidably connected to the bottom end of the outer wall of the annular plate 40. When the annular plate 40 reciprocates up and down, the annular plate 40 drives the baffle plate 43 to move up and down on one side of the outer wall of the slide plate 42. Because the baffle plate 43 does not rotate, when the separation shell 15 drives the material to rotate, the material is blocked when the baffle plate 43 moves. Because a group of baffle plates 43 are respectively matched with a group of discharge pipes 17, after the material is blocked, the discharge pipe 17 is below the material, thereby further assisting the material discharge operation, so that the material discharge speed is further improved, and the overall efficiency of the device is also improved.

[0037] Embodiment 2:

[0038] See also Figure 7 As shown, the outer wall of the separation shell 15 is fixedly connected with an eighth gear 44; the bottom end of the outer wall of the delivery pipe 4 is rotatably connected with a rotating rod 9 45; the outer wall of the rotating rod 9 45 is fixedly connected with a ninth gear 46, and the ninth gear 46 and the eighth bevel gear are meshed with each other; the outer wall of the rotating rod 9 45 is fixedly connected with a group of soft rods 47; one end of the outer wall of the soft rod 47 is fixedly connected with a vibration ball 48, and the vibration ball 48 matches the separation shell 15. When the separation shell 15 rotates, the rotation of the separation shell 15 drives the eighth gear 44 to rotate, so that the eighth gear 44 drives the ninth gear 46 to rotate, so that the ninth gear 4 6 drives the rotating rod 9 45 to rotate, so that the rotating rod 9 45 drives the soft rod 47 and the vibration ball 48 to rotate, so that the vibration ball 48 knocks on the separation shell 15 to generate vibration, so that the vibration helps the material to be discharged, and also makes it difficult for the material to adhere to the inner wall of the separation shell 15. Because the separation shell 15 is in a rotating state, the vibration ball 48 can knock on different positions of the separation shell 15, so that the separation shell 15 can vibrate at all places, so that the separation shell 15 transmits the vibration to the material, so that the material is not easy to adhere to the inner wall of the separation shell 15 under the condition of vibration, thereby avoiding the waste of material.

[0039] When the present invention is in use, the material is put into the feed shell 5. When the material enters the feed shell 5, it falls onto the quantitative discharge plate 30. At this time, the motor 6 drives the rotating shaft 7 to rotate, so that the rotating shaft 7 drives the rotating rod 9 to rotate through the transmission wheel 1 12 and the transmission belt 1 13, and the rotating rod 9 drives the circular rod 29 to rotate through the transmission wheel 2 31 and the transmission belt 2 32, so that the circular rod 29 drives the quantitative discharge plate 30 to rotate, so that the material is quantitatively discharged, thereby accurately controlling the feeding operation of the material, making the feeding more accurate, and preventing the material from entering the conveying pipe 4 at one time, causing the conveying pipe 4 to be blocked.

[0040] When the circular rod 29 rotates, the circular rod 29 drives the fifth bevel gear 33 to rotate, so that the fifth bevel gear 33 drives the rotating rod 34 to rotate through the sixth bevel gear 35, and the rotating rod 34 drives the soft rod 36 and the knocking ball 37 to rotate, so that the knocking ball 37 hits the feed shell 5, so that the material in the feed shell 5 vibrates, thereby further facilitating the discharge of the material, and the vibration force disperses the material, making it difficult for the material to adhere and coagulate.

[0041] When the material enters the conveying pipe 4 through the quantitative unloading plate 30, the air compressor body 3 generates a high-pressure airflow to provide power for material transportation, so that the material is transported in the conveying pipe 4, and when the material is transported, the rotation of the rotating rod 9 drives the connecting plate 10 and the cleaning plate 11 to rotate, so that the cleaning plate 11 cleans the inner wall of the conveying pipe 4, so that the material is not easy to accumulate or adhere to the conveying pipe 4, thereby ensuring that the conveying efficiency of the conveying pipe 4 is not easily reduced, and avoiding the resistance caused by material accumulation or adhesion, thereby reducing energy consumption, and reducing the probability of accumulated or adhered materials falling off and mixing into the material being transported.

[0042] When the connecting plate 10 rotates, the connecting plate 10 drives the rotating rod 22 and the third gear 23 on the rotating rod 22 to rotate. Because a pair of third gears 23 are meshed with the annular rack 24, the third gear 23 rotates through the annular rack 24, so that the third gear 23 drives the rotating rod 22 to rotate, and the rotating rod 22 drives the fan blades 25 to rotate, so that the blowing of the fan blades 25 enhances the transportation of materials, and the high-pressure airflow generated by the air compressor body 3 will also blow the fan blades 25, so that the fan blades 25 rotate. When the fan blades 25 rotate, they will also drive the rotating rod 22, the connecting plate 10, and the rotating rod 9 to rotate, thereby reducing the energy consumption of the motor 6. Each structure complements each other.

[0043] When the connecting plate 10 rotates, the connecting plate 10 drives the rotating rod 26 to rotate through the first square plate, so that the rotating rod 26 drives the fourth gear 27 to rotate. Because the pair of fourth gears 27 are meshed with the annular rack 1 24, when the fourth gear 27 rotates, the annular rack 1 24 rotates by itself, so that the fourth gear 27 drives the rotating rod 26 to rotate, and the rotating rod 26 drives the stirring plate 28 to rotate. When the material is conveyed, the stirring plate 28 stirs the material, thereby avoiding adhesion and condensation, thereby affecting the conveying efficiency or effect, and the stirring plate 28 breaks up the material, so that the conveying efficiency of the material is further improved.

[0044] When the material in the conveying pipe 4 enters the separation shell 15 through the high-pressure airflow generated by the air compressor body 3, the second bevel gear 21 is driven to rotate by the rotation of the rotating shaft 7, and the second bevel gear 21 is meshed with the first bevel gear 20, so that the second bevel gear 21 drives the cylinder 14 to rotate through the first bevel gear 20, and the cylinder 14 drives the separation shell 15 to rotate, so that centrifugal force is generated when the material enters the separation shell 15. At this time, the air in the material moves toward the center of the separation shell 15, and the material moves toward the inner wall of the separation shell 15 under the action of centrifugal force. The air will flow to the outside through the airflow pipe 18, and a filter screen 19 is fixedly connected to the top of the outer wall of the airflow pipe 18, so that a small part of the material flowing with the air is blocked by the filter screen 19, thereby avoiding the material from polluting the external environment, and when the filter screen 19 cannot block the material, a dust collector can be added to the filter screen 19 to further clean the material, so that the device can separate the air and the material while avoiding the material from affecting the environment. When the material is separated, the material is discharged through the discharge pipe 17.

[0045] When the separation shell 15 rotates, the separation shell 15 drives the reciprocating rod 39 and the seventh gear 41 on the reciprocating rod 39 to rotate. Since the seventh gear 41 is meshed with the annular rack 2 38, the seventh gear 41 rotates through the annular rack 2 38, so that the seventh gear 41 drives the reciprocating rod 39 to rotate, and the reciprocating rod 39 drives the annular plate 40 to reciprocate. When the material moves to the inner wall of the separation shell 15 under the action of centrifugal force, the reciprocating motion of the annular plate 40 will scrape the material, causing the material to move to the lower feeding pipe 17, thereby accelerating the material discharge efficiency.

[0046] When the annular plate 40 reciprocates up and down, the annular plate 40 drives the baffle 43 to move up and down on one side of the outer wall of the slide plate 42. Because the baffle 43 does not rotate, when the separation shell 15 drives the material to rotate, the material is blocked when the baffle 43 moves. Because a group of baffles 43 is matched with a group of discharge pipes 17 respectively, after the material is blocked, the discharge pipe 17 is below the material, thereby further assisting the material discharge operation, so that the material discharge speed is further improved, and the overall efficiency of the device is also improved.

[0047] When the separation shell 15 rotates, the rotation of the separation shell 15 drives the eighth gear 44 to rotate, so that the eighth gear 44 drives the ninth gear 46 to rotate, so that the ninth gear 46 drives the rotating rod 9 45 to rotate, so that the rotating rod 9 45 drives the soft rod 47 and the vibration ball 48 to rotate, so that the vibration ball 48 knocks on the separation shell 15 to generate vibration, so that the vibration assists the material to be discharged, and also makes it difficult for the material to adhere to the inner wall of the separation shell 15. Because the separation shell 15 is in a rotating state, the vibration ball 48 can knock on different positions of the separation shell 15, so that the separation shell 15 can generate vibration everywhere, so that the separation shell 15 transmits the vibration to the material, so that the material is not easy to adhere to the inner wall of the separation shell 15 under the condition of vibration, thereby avoiding the waste of material.
