Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, specifically to an anti-clogging spiral structure for lithium battery conductive agent conveying pipelines. Background Technology

[0002] Conductive agents are one of the key materials in lithium-ion batteries, mainly including carbon black, graphene, and carbon nanotubes. They enhance electrode conductivity and improve electron transport efficiency, helping batteries achieve high capacity and long cycle life, and are widely used in the new energy field.

[0003] Utility model patent CN222384616U discloses a conductive agent raw material preparation and mixing device. This device includes a mixing tank, a feeding tank at the top of the mixing tank, a storage bin inside the feeding tank, a spiral conveying roller inside the mixing bin, a second motor at the top of the feeding tank, and the spiral conveying roller connected to the second motor shaft. The mixing tank also includes a mixing chamber, a dispensing trough on one side above the dispensing trough, an electronic scale at the bottom of the dispensing trough, a pusher plate inside the dispensing trough, a telescopic rod on the back of the pusher plate, a top rod on the front of the pusher plate, a baffle plate between the dispensing trough and the mixing chamber, and a hinged connection between the baffle plate and the mixing tank. The spiral conveying roller extends into the top of the dispensing trough. This utility model uses the second motor and the spiral conveying roller to transport the raw material into the dispensing trough, weighs it quantitatively using the electronic scale, and finally pushes the quantitatively weighed raw material into the mixing chamber for mixing using the telescopic rod and the pusher plate, achieving the effect of weighing and quantitatively dispensing raw materials.

[0004] In this conductive agent raw material preparation and mixing device, when the conductive agent is discharged outward through the discharge pipe after mixing, the mixed material is prone to adhere to or clump on the inner wall of the pipe due to the single straight-through structure of the discharge pipe. If it is not treated regularly, it may cause blockage of the discharge pipe in the long term, affecting the continuous operation efficiency of the equipment. In view of this, we propose an anti-blockage spiral structure for the lithium battery conductive agent conveying pipeline. Utility Model Content

[0005] The purpose of this invention is to provide an anti-clogging spiral structure for lithium battery conductive agent delivery pipelines, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A lithium battery conductive agent delivery pipeline anti-clogging spiral structure includes a mixing tank. A delivery pipe for discharging the conductive agent is fixed to the bottom of the mixing tank. A discharge pipe is connected to the bottom of the end of the delivery pipe. A spiral delivery assembly is installed in the delivery pipe. The spiral delivery assembly includes an end plate detachably connected to the end face of the delivery pipe and an auger sleeved inside the delivery pipe and capable of axial rotation within the delivery pipe. A delivery motor is coaxially connected to the auger. A pair of guide rods are symmetrically arranged on the end face of the delivery pipe, passing through the end plate and slidably connected to it. A cleaning mechanism is hinged to the outer wall of the mixing tank above the delivery pipe. The cleaning mechanism includes a housing and a rotating brush sleeved within the housing. A rotating motor is coaxially connected to the rotating brush. By pulling the spiral delivery assembly out of the delivery pipe and rotating the cleaning mechanism on the mixing tank, the rotating brush can clean the surface of the auger.

[0008] Preferably, protrusions are provided on both the left and right outer surfaces of the conveying pipe, and the first end of the guide rod is inserted into the end of the protrusion and fixedly connected to the protrusion.

[0009] In this setup, the boss provides a mounting point for the guide rod, ensuring that the guide rod is securely connected to the delivery pipe.

[0010] Preferably, the conveying motor is fixed to the end face of the end plate, and sleeve plates are provided at the outer periphery of both the left and right ends of the end plate. The end of the guide rod passes through the sleeve plate and is provided with a stop post, which is used to prevent the sleeve plate from coming off the guide rod.

[0011] In this configuration, the sleeve plate slides along the guide rod, allowing the end plate to move along the guide rod, while the stop prevents the end plate from detaching from the guide rod.

[0012] Preferably, a pair of hinge seats are fixed on the tail end face of the cover, and a pair of fixed seats are fixed on the outer surface of the mixing tank, with a hinge shaft passing through the end of the hinge seat and the outer end of the fixed seat;

[0013] In this configuration, the hinge base and the fixed base are connected by a hinge shaft, allowing the cleaning mechanism to rotate around the hinge shaft and adjust its position.

[0014] Preferably, the cover has a hollow cylindrical structure, and an opening is provided on the outer peripheral surface of the cover near the screw conveyor assembly. When the cover is rotated toward the screw conveyor assembly, the opening on the cover faces the screw conveyor assembly. When the edge of the opening abuts against the outer peripheral surface of the end plate, the axis of the rotating brush is parallel to the axis of the auger.

[0015] In this setup, the hollow cylindrical structure, combined with the through-hole, allows the rotating brush to be aligned with the auger, and the parallel axes ensure that the cleaning range covers the surface of the auger.

[0016] Preferably, the rotating motor is fixed to the first end face of the cover, the output shaft of the rotating motor passes through the cover and is rotatably connected to the cover, and the rotating brush is sleeved and fixed to the outside of the output shaft of the rotating motor.

[0017] In this setup, the rotating motor drives the rotating brush to rotate via the output shaft, thereby cleaning the surface of the auger.

[0018] Preferably, a base is fixed on the outer peripheral surface of the casing near the mixing tank, and an end seat is provided on the outer surface of the mixing tank corresponding to the position of the base. When the cleaning mechanism is rotated so that the base abuts against the end seat, the base and the end seat are fixedly connected by a detachable bolt with a handle.

[0019] In this configuration, the base and end seat are secured with bolts with handles to ensure the cleaning mechanism remains in a stable position during operation.

[0020] Preferably, a pair of pull rods are fixed to the front end of the cover, and the cleaning mechanism can be rotated outside the mixing tank by holding the pull rods;

[0021] In this setup, the lever provides the operator with a point of leverage, making it easy to rotate the cleaning mechanism.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] This anti-clogging spiral structure for the lithium battery conductive agent conveying pipeline utilizes an axially rotatable auger within the spiral conveying assembly. The auger's rotation dynamically scrapes the inner wall of the conveying pipe, preventing conductive agent adhesion and accumulation. Simultaneously, a detachable end plate and guide rod structure, along with a cleaning mechanism hinged to the outer wall of the mixing tank, allow for further surface cleaning of the auger after it is pulled out along the guide rod during shutdown. This prevents residual material carried by the auger from hardening and clogging the pipeline, reducing the risk of blockage in the discharge pipe due to material adhesion or caking, extending continuous operating time, and lowering maintenance frequency.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figures 1-6 A lithium battery conductive agent delivery pipeline anti-clogging spiral structure includes a mixing tank 100, with a delivery pipe 110 for discharging conductive agent fixed to the bottom end of the mixing tank 100. A discharge pipe 111 is connected to the bottom of the end of the delivery pipe 110. A spiral delivery assembly 200 is installed in the delivery pipe 110. The spiral delivery assembly 200 includes an end plate 210 detachably connected to the end face of the delivery pipe 110 by bolts and an auger 220 sleeved inside the delivery pipe 110 and capable of axial rotation within the delivery pipe 110. A delivery motor 221 is coaxially connected to the auger 220 and fixed to the end face of the end plate 210. When the delivery motor 221 is started, the auger 220 in the spiral delivery assembly 200 rotates under the drive of the delivery motor 221, allowing the auger 220 to push the conductive agent along the delivery pipe 110 towards the discharge pipe 111, reducing the residue and accumulation of conductive agent in the delivery pipe 110.

[0036] like Figure 2-4As shown, in this utility model, protrusions 112 are provided on the outer surfaces of both the left and right sides of the conveying pipe 110. A pair of guide rods 120 are symmetrically arranged on the end face of the conveying pipe 110. The first end of the guide rod 120 is inserted into the end of the protrusion 112 and fixedly connected to the protrusion 112. Sleeves 211 are provided on the outer periphery of both the left and right ends of the end plate 210. The end of the guide rod 120 passes through the sleeve 211, allowing the end plate 210 to slide along the guide rod 120. The cooperation between the protrusion 112 and the guide rod 120 achieves the stable installation of the guide rod 120. The sliding connection between the sleeve 211 and the guide rod 120 allows the end plate 210 to be pulled out or pushed in along the guide rod 120, which facilitates the disassembly and installation of the screw conveyor assembly 200. A stop post is provided at the end of the guide rod 120. The stop post is used to prevent the sleeve 211 from falling off the guide rod 120, preventing the end plate 210 from falling off the guide rod 120 during the sliding process.

[0037] like Figure 1 ,and Figure 5 As shown, specifically, a cleaning mechanism 300 is hinged to the outer wall of the mixing tank 100 located above the conveying pipe 110. The cleaning mechanism 300 is hinged to the mixing tank 100, allowing it to be rotated to a suitable position when needed. The cleaning mechanism 300 includes a cover 310 and a rotating brush 320 sleeved inside the cover 310. The rotating brush 320 is coaxially connected to a rotating motor 321, which is fixed to the front end face of the cover 310. The output shaft of the rotating motor 321 passes through the cover 310 and is rotatably connected to it. The rotating brush 320 is sleeved and fixed to the outside of the output shaft of the rotating motor 321. When the rotating motor 321 is started, it drives the rotating brush 320 to rotate, which can brush the parts that need to be cleaned. The cover 310 provides protection for the rotating brush 320 and the rotating motor 321.

[0038] like Figure 3 and Figure 5 As shown, furthermore, a pair of hinge seats 311 are fixed on the tail end face of the cover 310, and a pair of fixed seats 130 are fixed on the outer surface of the mixing tank 100. A hinge shaft passes through the end of the hinge seat 311 and the outer end of the fixed seat 130. A pair of pull rods 314 are fixed on the front end of the cover 310. By holding the pull rods 314, the cleaning mechanism 300 can be driven to rotate around the hinge shaft in the mixing tank 100. The cooperation of the hinge seat 311, the fixed seat 130 and the hinge shaft provides a rotation fulcrum for the cleaning mechanism 300. By holding and turning the pull rods 314, the operator can make the cleaning mechanism 300 rotate around the hinge shaft, so that it can move in the direction of the screw conveyor assembly 200.

[0039] like Figure 5 and Figure 6As shown, the housing 310 has a hollow cylindrical structure, and an opening is provided on the outer peripheral surface of the housing 310 near the screw conveyor assembly 200. When the housing 310 is rotated toward the screw conveyor assembly 200, the opening on the housing 310 faces the screw conveyor assembly 200. The hollow cylindrical structure and opening design of the housing 310 ensure that the rotating brush 320 can contact the surface of the auger 220 that needs to be cleaned when rotating. When the edge of the opening abuts against the outer peripheral surface of the end plate 210, the axis of the rotating brush 320 is parallel to the axis of the auger 220. By pulling the screw conveyor assembly 200 out of the conveying pipe 110 and rotating the cleaning mechanism 300 on the mixing tank 100, the rotating brush 320 can clean the surface of the auger 220. At this time, the conveying motor 221 is started to rotate the auger 220. With the combination of the rotating auger 220 and the brushing action of the rotating brush 320, the surface of the auger 220 can be thoroughly cleaned.

[0040] like Figure 1 and Figure 3 As shown, it is worth noting that a base 312 is fixed on the outer peripheral surface of the casing 310 near the mixing tank 100. An end seat 140 is provided on the outer surface of the mixing tank 100 corresponding to the position of the base 312. When the cleaning mechanism 300 is rotated so that the base 312 abuts against the end seat 140, the base 312 and the end seat 140 are fixedly connected by a detachable bolt with a handle 313. The base 312, end seat 140, and bolt with a handle 313 cooperate to fix the cleaning mechanism 300 after it has rotated to its position, preventing the cleaning mechanism 300 from shaking or shifting during operation.

[0041] It is worth noting that the conveyor motor 221 and the rotary motor 321 involved in this utility model are both existing conventional technologies, and will not be described in detail here.

[0042] In this embodiment, the anti-clogging spiral structure for the lithium battery conductive agent delivery pipeline works as follows: First, the conveying motor 221 is started, causing the auger 220 to rotate within the delivery pipe 110. Under the rotation of the auger 220, the conductive agent in the mixing tank 100 is delivered through the delivery pipe 110 to the discharge pipe 111 for discharge. Then, when cleaning of the auger 220 is required, the conveying motor 221 is turned off, and the bolts between the delivery pipe 110 and the end plate 210 are removed. The end plate 210 is then moved along the guide rod 120. 10 and auger 220 pull out the conveying pipe 110; then, hold the pull rod 314 to rotate the cleaning mechanism 300 so that the opening of the cover 310 is aligned with the auger 220, and fix the base 312 and the end seat 140 with the bolt with handle 313; finally, start the rotating motor 321 to drive the rotating brush 320 to rotate and clean the surface of the auger 220. At the same time, the conveying motor 221 can be started to drive the auger 220 to rotate, so that the surface of the auger 220 is cleaned more thoroughly. After cleaning is completed, reverse the operation to reset all components.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
