Description

Technical Field

[0001] This invention relates to the field of pneumatic conveying technology, and in particular to a continuous feeding device for the production of hard carbon anode materials. Background Technology

[0002] Hard carbon anode materials are a class of anode materials that have been extensively studied in lithium-ion batteries in recent years. Compared with traditional graphite anodes, hard carbon anode materials exhibit better performance in some specific application areas (such as high capacity and high safety), especially showing great potential in sodium-ion batteries and some high-performance lithium-ion batteries.

[0003] Carbonization is a crucial step in the production of hard carbon anode materials, requiring pre-treated raw materials to be fed into a high-temperature furnace for carbonization. A common conveying equipment is the pneumatic conveying system: pneumatic conveyors are frequently used to transfer powdery materials from one location to the high-temperature furnace, using compressed air or vacuum to propel the material flow. However, traditional pneumatic conveying equipment is prone to blockage at the discharge port due to its narrowing opening, often requiring regular inspections and even the installation of knocking devices to prevent clogging, which is very inconvenient. Therefore, we propose a novel continuous feeding device to prevent discharge port blockage. Summary of the Invention

[0004] To address the technical problem of easy blockage at the discharge port in existing pneumatic conveying devices, the present invention adopts the following technical solution:

[0005] A continuous feeding device for the production of hard carbon anode materials includes a suction mechanism and a sealing cap fixed above the opening of a container at the end of the conveying process. The suction mechanism includes a receiving box with an overall open-to-the-upward rectangular box structure. The left and right sides of the receiving box have the same through arc-shaped groove near the bottom. One outlet of the arc-shaped groove is connected to a high-speed air duct. The end of the high-speed air duct away from the receiving box is connected to a Roots blower. A sealing top cover is fixed to the top of the receiving box. A flange connection is pre-installed in the middle of the sealing top cover. The receiving box is located away from the high-speed air duct. One end of the high-speed air duct is connected to the sealing cover; the top of the sealing cover is provided with an upwardly protruding outer box, and an exhaust mechanism is provided inside the outer box; used to separate the material mixed with the high-speed airflow. The air outlet end of the high-speed air duct extends into the lower part of the flange pipe, and a baffle is fixed between the outer wall of the high-speed air duct and the sealing top cover. A combined bearing seat is embedded in the middle of the baffle, and a shaking rocker arm is rotatably connected in the middle of the combined bearing seat. An arc-shaped hook rod extending into the flange pipe is fixed on the upper surface of the end of the shaking rocker arm near the flange pipe.

[0006] A further feature of this invention is that a mounting post extending into the centerline of the high-speed air duct is fixed near the center of its circumferential inner wall. Two symmetrical tapered roller bearings are embedded in the middle of the mounting post, and a common transmission rod is rotatably connected between the two tapered roller bearings. The transmission rod coincides with the centerline of the high-speed air duct. Fan blades and a drive pulley are fixed at both ends of the transmission rod, with the drive pulley located near the suction mechanism. Under the action of the high-speed airflow, the fan blades provide rotational power to the transmission rod. A suspended bearing bracket is fixed above the drive pulley on the lower surface of the sealing top cover, and a horizontally extending transmission shaft is rotatably connected within the bearing bracket. The driven pulley and the driving pulley are fixed at their respective ends, and the same conveyor belt is wound between the outer circumferences of the driven pulley and the driving pulley; a connecting rod is rotatably connected to the side of the rotating wheel near the edge of the circumference; and a reciprocating slider is rotatably connected to the other end of the connecting rod; two vertical grooved slide rails with opposite openings are fixed on the lower surface of the sealing top cover; and the reciprocating slider is slidably connected between the two grooved slide rails. A strip hole is opened on the side of the end of the shaking rocker away from the arc-shaped hook rod; the reciprocating slider has a horizontal U-shaped structure, and the reciprocating slider tends to fit over the end of the shaking rocker; a wear-resistant round rod passing through the strip hole is fixed between the ends of the two support rods of the reciprocating slider.

[0007] A further feature of this invention is that the combined bearing housing is fixedly connected by two semi-annular retaining rings, and each of the two retaining rings has an arc-shaped groove on its opposite side. The arc-shaped inner wall of the arc-shaped groove is fitted with balls, and a cylindrical rotating shaft adapted to the inner diameter of the arc-shaped groove is reserved in the middle of the shaking rocker arm. With this configuration, the shaking rocker arm can rotate more smoothly in the combined bearing housing, reducing frictional resistance.

[0008] A further feature of this invention is that the outer diameter of the high-speed duct is equal to the inner diameter of the arc-shaped groove, and a rectangular through hole adapted to the cross-sectional size of the conveyor belt is opened on the outer wall of the high-speed duct near the upper part of the drive pulley; this ensures that the conveyor belt passes through normally.

[0009] A further feature of the present invention is that the receiving box of the material suction mechanism is sealed with a reducer at the end away from the high-speed air duct, and a discharge bend is inserted into the outer circumference of the sealing cover near the top. A conveying pipe is connected between the discharge bend and the reducer. The conveying pipe is a flexible hose. It can automatically generate fluctuations at the bend due to the impact of the material, thereby forming a shaking, which is beneficial for clearing the material passing through the bend.

[0010] A further feature of this invention is that the sealing cap comprises two stacked cylindrical tubes of different diameters and tangent sides, with the discharge bend located above the tangent position of the two tubes; this reduces the use of bends, minimizes the overall length and number of bends of the conveying pipe, and improves conveying efficiency.

[0011] A further feature of the present invention is that the exhaust mechanism includes a filter screen clamp plate that is snapped into the outer casing at a 45-degree angle. The filter screen clamp plate has a circular hole in the middle, and a filter screen is snapped into the circular hole. A spring rope parallel to the surface of the filter screen is provided on the upper surface of the filter screen. A centrifugal fan is provided on the side of the outer casing near the top.

[0012] A further feature of this invention is that an inclined mounting plate extending upwards towards the filter screen is fixed to the upper part of the vertical inner wall of the outer casing near the filter screen plate. Two symmetrical shaft seats are fixed to the front of the inclined mounting plate near its end. Coaxial anti-detachment bearings are embedded in each of the two shaft seats, and a reciprocating slide rod is slidably connected between the two anti-detachment bearings. The reciprocating slide rod is perpendicular to the surface of the filter screen plate, and a cylindrical deep hole coaxial with the reciprocating slide rod is opened at the top of the reciprocating slide rod. A groove is opened at the bottom of the cylindrical deep hole... A reset insertion hole is passed through the bottom end of the reciprocating slide rod, and a sliding notch is opened on the side of the reciprocating slide rod near the mounting inclined plate. A fixing block extending into the sliding notch is fixed on the side of the mounting inclined plate near the reciprocating slide rod, and a reset top rod extending into the reset insertion hole is fixed at the end of the fixing block. A hinge notch is opened at the bottom end of the reciprocating slide rod, and a hook is rotatably connected in the hinge notch. One end of the hook near the spring rope protrudes from the side of the reciprocating slide rod and hooks the spring rope, and a reset tension spring is provided between the other end of the hook and the reciprocating slide rod.

[0013] A further feature of this invention is that a strip-shaped spring support plate is fixed to the outer circumference of the reciprocating slide rod near its bottom end, and a compression spring is provided between the upper surface of the spring support plate near the mounting inclined plate and the lowest shaft seat; a rack is reserved on the side of the outer circumference of the reciprocating slide rod away from the compression spring, a reduction motor is fixed to the end of the mounting inclined plate, and an intermittent gear that meshes with the rack is fixed to the top of the output shaft of the reduction motor; through the reduction motor and the compression spring, the reciprocating slide rod can be moved back and forth axially, thereby realizing the intermittent hooking and pulling of the spring rope.

[0014] A further feature of this invention is that a limiting block is fixed to the outer circumferential wall of the reciprocating slide rod near the top. By setting the limiting block, it can be ensured that the reciprocating slide rod will not travel a greater distance when moving downwards, thus preventing it from puncturing the filter screen.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. By setting an arc-shaped hook rod that extends into the flange pipe, it can work with a high-frequency vibrating rocker arm to continuously poke and pull the material blocking the outlet during discharge. That is, it loosens the compacted material while pulling it downward, thereby accelerating the fall of the material and effectively preventing the material from forming a blockage at the outlet.

[0017] 2. By setting a transmission rod driven by the fan blades, a continuous power output can be provided for the shaking of the rocker arm during use. Moreover, the drive side and the top-pump discharge side are separated by a baffle plate to ensure that the material pulled down by the hook will not affect the drive side, thus improving the stability of unloading.

[0018] 3. By setting an inclined filter screen and a flexible hose at the bend, it is beneficial to accelerate the flow of gas and increase the suction effect; in conjunction with the spring rope on the surface of the filter screen, when blockage occurs, simply pull down the spring rope and then release it suddenly to knock the surface of the filter screen from top to bottom, thereby shaking off the dust stuck to the filter screen.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] In this embodiment, refer to Figures 1-8A continuous feeding device for the production of hard carbon anode materials includes a suction mechanism 1 and a sealing cover 3 fixed above the opening of a barrel at the end of the conveying process. The suction mechanism 1 includes a receiving box with an overall rectangular box-shaped structure that opens upwards. The receiving box has a through arc-shaped groove 101 on both sides near the bottom. One outlet of the arc-shaped groove 101 is connected to a high-speed air duct 12. The end of the high-speed air duct 12 away from the receiving box is connected to a Roots blower 11. A sealing top cover 9 is fixed to the top of the receiving box. A flange pipe 8 is pre-installed in the middle of the sealing top cover 9. The end of the receiving box away from the high-speed air duct 12 is connected to the sealing cover 3. The top of the sealing cover 3 has an upwardly protruding outer casing 4, and an exhaust mechanism is installed inside the outer casing 4 to mix the high-speed airflow with the material. Material separation: the outlet end of the high-speed air duct 12 extends into the lower part of the flange connecting pipe 8, and a baffle plate 15 is fixed between the outer wall of the high-speed air duct 12 and the sealing top cover 9. A combined bearing seat 16 is embedded in the middle of the baffle plate 15, and a vibrating rocker arm 24 is rotatably connected to the middle of the combined bearing seat 16. An arc-shaped hook rod 14 extending into the flange connecting pipe 8 is fixed on the upper surface of the end of the vibrating rocker arm 24 near the flange connecting pipe 8. By setting the arc-shaped hook rod 14 extending into the flange connecting pipe 8, when the material is discharged, it can work with the high-frequency vibrating rocker arm 24 to continuously poke and pull the material blocked at the outlet. That is, it loosens the compacted material while pulling the material downward, thereby accelerating the falling of the material and effectively preventing the material from forming a blockage at the outlet.

[0030] Reference Figures 4-6A mounting post 10 extending into the centerline is fixed near the center of the inner circumference of the high-speed air duct 12. Two symmetrical tapered roller bearings are embedded in the middle of the mounting post 10, and the two tapered roller bearings are rotatably connected to the same transmission rod 23. The transmission rod 23 coincides with the centerline of the high-speed air duct 12. Fan blades 22 and a drive pulley are fixed at both ends of the transmission rod 23, and the drive pulley is located at the end near the suction mechanism 1. Under the action of high-speed airflow, the fan blades 22 provide rotational power to the transmission rod 23. A suspended bearing bracket is fixed above the drive pulley on the lower surface of the sealing top cover 9, and a horizontally extending transmission shaft 20 is rotatably connected in the bearing bracket. A driven pulley 19 and a rotating wheel are fixed at both ends of the transmission shaft 20, and the same conveyor belt 21 is wound between the outer circumference of the driven pulley 19 and the drive pulley. The rotating wheel is near the vibrating rocker arm 24. A connecting rod 18 is rotatably connected to one side near the circumferential edge; and a reciprocating slider 17 is rotatably connected to the other end of the connecting rod 18; two vertically oriented grooved slide rails 25 with opposite openings are fixed on the lower surface of the sealing top cover 9; and the reciprocating slider 17 is slidably connected between the two grooved slide rails 25. A strip hole 242 is opened on the side of the end of the shaking rocker arm 24 away from the arc hook rod 14; the reciprocating slider 17 has a horizontal U-shaped structure and tends to fit the end of the shaking rocker arm 24; a wear-resistant round rod passing through the strip hole 242 is fixed between the ends of the two support rods of the reciprocating slider 17. By setting a transmission rod 23 driven by the fan blade 22, a continuous power output can be provided for the shaking of the shaking rocker arm 24 during use. Moreover, the drive side and the top-pump discharge side are separated by a baffle plate 15 to ensure that the material hooked and dropped will not affect the drive side, thus improving the stability of unloading.

[0031] Reference Figures 5-6 The combined bearing housing 16 is fixedly connected by two semi-annular retaining rings, and each of the two retaining rings has an arc-shaped rotating groove 161 on its opposite side. The arc-shaped inner wall of the arc-shaped rotating groove 161 is fitted with balls, and a cylindrical rotating shaft 241 that matches the inner diameter of the arc-shaped rotating groove 161 is reserved in the middle of the vibrating rocker arm 24. With this arrangement, the vibrating rocker arm 24 can rotate more smoothly in the combined bearing housing 16, reducing frictional resistance.

[0032] Reference Figure 4 The outer diameter of the high-speed air duct 12 is equal to the inner diameter of the arc groove 101, and the outer wall of the high-speed air duct 12 has a rectangular through hole that matches the cross-sectional size of the conveyor belt 21 near the top of the drive pulley; this ensures that the conveyor belt 21 can pass through normally.

[0033] Reference Figure 2 and Figure 4The receiving box of the suction mechanism 1 is sealed with a reducer 2 at the end away from the high-speed air duct 12, and a discharge bend 6 is inserted into the outer circumference of the sealing cover 3 near the top. A conveying pipe 7 is connected between the discharge bend 6 and the reducer 2. The conveying pipe 7 is a flexible hose. The flexible hose material of the conveying pipe 7 can automatically generate fluctuations at the bend due to the impact of the material, which will then form a shaking, which is beneficial to clear the material passing through the bend.

[0034] Reference Figure 1 The sealing cap 3 is composed of two stacked cylindrical tubes of different diameters and tangent sides, and the discharge bend 6 is located above the tangent position of the two tubes. By setting it up in this way, the use of bends can be reduced, the overall length of the conveying pipe 7 and the number of bends can be minimized, and the conveying efficiency can be improved.

[0035] Reference Figure 7 The exhaust mechanism includes a filter clip plate 13 that is snapped into the outer casing 4 at a 45-degree angle. The filter clip plate 13 has a round hole in the middle, and a filter 131 is snapped into the round hole. A spring rope 29 parallel to the surface of the filter 131 is provided on the upper surface of the filter 131. A centrifugal fan 5 is provided on the side of the outer casing 4 near the top, which helps to accelerate the flow of gas and increase the suction effect. With the spring rope 29 on the upper surface of the filter 131, when blockage occurs, simply pull down the spring rope 29 and then release it suddenly to knock the surface of the filter 131 from top to bottom, thereby shaking off the dust stuck to the filter 131.

[0036] Reference Figure 1 , Figures 7-8The vertical inner wall of the outer casing 4, near the filter screen plate 13, is fixed with an inclined mounting plate 26 extending above the filter screen 131. Two symmetrical shaft seats 27 are fixed near the end of the front of the inclined mounting plate 26. Coaxial anti-detachment bearings are embedded in each of the two shaft seats 27, and the same reciprocating slide rod 30 is slidably connected between the two anti-detachment bearings. The reciprocating slide rod 30 is perpendicular to the surface of the filter screen plate 13. A cylindrical deep hole 3001, coaxial with the reciprocating slide rod 30, is opened at the top of the reciprocating slide rod 30. A reset insertion hole 3002, communicating with the bottom end of the reciprocating slide rod 30, is opened at the bottom end of the cylindrical deep hole 3001. A sliding notch is opened on the side of the reciprocating slide rod 30 near the inclined mounting plate 26. A fixing block 32 extending into the sliding notch is fixed on the side of the inclined mounting plate 26 near the reciprocating slide rod 30. The end of 2 is fixed with a reset push rod 31 extending into the reset socket 3002; the bottom end of the reciprocating slide rod 30 has a hinge notch 3003, and a hook 33 is rotatably connected in the hinge notch 3003. The end of the hook 33 near the spring rope 29 protrudes from the side of the reciprocating slide rod 30 and hooks the spring rope 29. A reset tension spring is provided between the other end of the hook 33 and the reciprocating slide rod 30. When it is necessary to pull the spring rope 29, simply move the reciprocating slide rod 30 downward along the axis of the reciprocating slide rod 30. After the tip of the protruding hook 33 hooks the spring rope 29, move the reciprocating slide rod 30 in the opposite direction. After the whole thing moves upward a certain distance, the end of the hook 33 near the spring rope 29 will be touched by the reset push rod 31, which will then rotate to quickly release the hooked spring rope 29 and form an elastic force.

[0037] Reference Figure 1 , Figures 7-8 A strip-shaped spring support plate 3004 is fixed to the outer circumference of the reciprocating slide bar 30 near the bottom end, and a compression spring is provided between the upper surface of the end of the spring support plate 3004 near the mounting inclined plate 26 and the lowest shaft seat 27; a rack is reserved on the side of the outer circumference of the reciprocating slide bar 30 away from the compression spring, a reduction motor 28 is fixed to the end of the mounting inclined plate 26, and an intermittent gear 2801 that meshes with the rack is fixed to the top of the output shaft of the reduction motor 28; through the reduction motor 28 and the compression spring, the reciprocating slide bar 30 can be moved back and forth in the axial direction, thereby realizing the intermittent hooking and pulling of the spring rope 29.

[0038] In this invention, a limiting block is fixed near the top of the circumferential outer wall of the reciprocating slide bar 30. By setting the limiting block, it can be ensured that the reciprocating slide bar 30 will not move too far downwards and puncture the filter screen 131.

[0039] Working Principle: Before use, the bottom outlet of the raw material barrel to be conveyed is sealed and connected to the flange pipe 8. Then, the sealing cap 3 is fastened to the top opening of the barrel at the end position. Then, the Roots blower 11 is started to draw in the air. The high-speed airflow generated enters the reducer pipe 2 and the conveying pipe 7 through the high-speed air duct 12. At this time, a strong negative pressure is generated below the flange pipe 8, which draws in the material mixed with the gas and sends it to the sealing cap 3. At this time, the material falls, and a small amount of gas mixed with the material is drawn in by the centrifugal blower 5 and adsorbed on the lower surface of the filter screen 131. At the same time, by setting the arc-shaped hook rod 14 that extends into the flange pipe 8, the high-frequency vibrating rocker arm 24 can continuously vibrate the outlet during discharge. The material that is blocked is poked and hooked, that is, the compacted material is loosened while the material is pulled downward, thereby accelerating the falling of the material. When the suction effect of the filter screen 131 is not good, the reduction motor 28 is started. Under the action of the intermittent gear 2801 and the compression spring, the reciprocating slide bar 30 moves axially and reciprocates. When it moves downward to the bottom, the tip of the protruding hook 33 will hook the spring rope 29. Then, the reciprocating slide bar 30 moves in the opposite direction. After the whole body moves upward a certain distance, the end of the hook 33 near the spring rope 29 will be touched by the reset rod 31, which will then rotate to quickly release the hooked spring rope 29, forming an elastic force and hitting the upper surface of the filter screen 131 to remove dust.
