[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0035] Example 1

[0036] See also Figures 1-5 A negative electrode material turnover unloading device comprises a kiln car 1 and a track 2 passing through a tunnel kiln. The kiln car 1 is used to load negative electrode materials for battery conduction, and the track 2 plays a role in supporting and guiding the kiln car 1. The tunnel kiln commonly used for heating negative electrode materials is divided into a preheating zone, a heating zone and a cooling zone. The kiln car 1 carries the negative electrode materials into the heating zone to achieve high-temperature heating and carbonization. Since the temperature inside the tunnel kiln is relatively high, the loading and unloading of negative electrode materials in the existing tunnel kiln is usually completed outside the tunnel kiln, that is, it is necessary to open and close the sealing doors at both ends of the tunnel kiln, which has the defects of inconvenient loading and unloading of negative electrode materials and low processing efficiency.

[0037] In the present technical solution, the track 2 is fixedly arranged on the two side walls in the tunnel kiln, that is, it is suspended, wherein the track 2 is arranged near the bottom, and brackets 3 that roll with the track 2 are arranged on both sides of the kiln car 1, and the kiln car 1 is in a suspended state, and its position in the tunnel kiln will change when it runs along the track 2. Preferably, at least two rollers 31 are arranged on the outer side of the bracket 3, wherein the bracket 3 is a door-type frame structure, and a guide groove 21 that rolls with the roller 31 is opened on the top of the track 2, and the roller 31 can drive the kiln car 1 to move when rolling in the guide groove 21.

[0038] The above-mentioned tracks 2 are all located in the tunnel kiln. The front and rear ends of the kiln car 1 are welded with traction plates 12. The function of the traction plates 12 is to connect with the external wire rope. The track 2 is a rectangular frame structure and traction rope guide sleeves 22 are welded at both ends. When in use, the wire rope is passed through the traction rope guide sleeves 22, and then a winch is installed on the outside of both ends of the tunnel kiln. After the wire rope passes through the sealing door of the tunnel kiln, it is connected to the winding roller on the winch, thereby the kiln car 1 can be controlled to move in the tunnel kiln through the winch.

[0039] Further, a rectangular feeding tube 4 is provided at the bottom of the kiln car 1, and the kiln car 1 is also rectangular in shape, in order to increase the loading capacity of the negative electrode material. A row of feeding wheels 5 are rotatably connected to the bottom of the rectangular feeding tube 4, and the function of the feeding wheels 5 is to block the rectangular feeding tube 4 and discharge the negative electrode material in the rectangular feeding tube 4 downward when rotating. In specific implementation, it is preferred that a wheel cover 41 with a semicircular cross section is welded to the bottom of the rectangular feeding tube 4, and the center of the wheel cover 41 is eccentrically arranged relative to the inner cavity of the rectangular feeding tube 4, and support shafts 411 are welded on both sides of the wheel cover 41, and the feeding wheel 5 is sleeved on the support shaft 411 and the two are rotatably connected, and the axis of the feeding wheel 5 is close to the inner cavity wall of the rectangular feeding tube 4, and the function of this setting is to reduce the resistance of the feeding wheel 5 to rotate, and at the same time, it will not be squeezed and pushed by the material in the rectangular feeding tube 4, and the outer peripheral wall of the feeding wheel 5 is provided with V-shaped grooves 51 evenly distributed in the circumferential direction, and the function of the V-shaped grooves 51 is to collect the negative electrode material.

[0040] A conveyor belt 6 is provided in the tunnel kiln in the cooling zone, one end of which extends to the outside of the tunnel kiln. Specifically, a window for the belt 61 to pass through can be opened on the side wall of the tunnel kiln. The outer peripheral wall of the belt 61 of the conveyor belt 6 is provided with evenly distributed paddles 7, which have the function of driving the unloading wheel 5 to rotate, that is, when the belt 61 is running, the unloading wheel 5 will be driven to rotate, so that the material in the rectangular unloading tube 4 is discharged downward onto the belt 61. When the belt 61 is running, the negative electrode material on it will be transferred to the outside, realizing the automatic unloading function. The kiln car 1 is moved so that different unloading wheels 5 can be used in turn with the paddles 7 to discharge all the negative electrode materials in the kiln car 1.

[0041] A double barrel material distributor 9 with a material discharging function is arranged above the preheating zone in the tunnel kiln. The function of the double barrel material distributor 9 is to put the negative electrode material to be processed into the kiln car 1 and to evenly fill the negative electrode material in the kiln car 1 .

[0042] Specifically, the dual-barrel material homogenizer 9 includes two turnover barrels 91 with the function of synchronous and opposite rotation. The turnover barrels 91 are temporary storage barrels for the negative electrode material. The two turnover barrels 91 are horizontally distributed and parallel. The outer peripheral walls of the two turnover barrels 91 are attached and are provided with rectangular blanking ports 911. The rectangular blanking ports 911 are also the inlets for the negative electrode material to enter the turnover barrels 91. During the rotation of the two turnover barrels 91, the rectangular blanking ports 911 of each present a periodically opposite state. The two turnover barrels 91 also have the function of revolving around the midline between them. Here, the midline is the parallel line in the middle of the axes of the two turnover barrels 91. It should be noted that when the rectangular blanking ports 911 on the two turnover barrels 91 are opposite and then revolve, there is a certain gap around the rectangular blanking ports 911, but this gap will not cause the granular negative electrode material to fall. When the rectangular blanking ports 911 on the two turnover barrels 91 are opposite and then revolve, the granular negative electrode material inside the two will flow, so that the granular negative electrode material will be evenly distributed in the turnover barrels 91. At this time, if the rectangular blanking ports 911 on the two turnover barrels 91 are controlled to open downward, the negative electrode material in the turnover barrels 91 will uniformly fall as a whole into the kiln car 1 parked below, so that the negative electrode material can be evenly filled in the kiln car.

[0043] Among them, the above-mentioned dual-barrel material homogenizer 9 includes a rectangular rotating frame 92, a rack 93, a first transmission gear 94 and a control oil cylinder 95. The two turnover barrels 91 are rotatably connected inside the rectangular rotating frame 92. Fixedly connected to the adjacent ends of the two turnover barrels 91 are first transmission gears 94. The control oil cylinder 95 is fixedly arranged on one side of the rectangular rotating frame 92 and its output shaft is fixedly connected to the rack 93. The two sides of the rack 93 are simultaneously meshed with the first transmission gears 94 on the two turnover barrels 91. When the rack 93 moves, it will simultaneously drive the first transmission gears 94 on its two sides to rotate, thereby being able to control the synchronous and opposite rotation of the two turnover barrels 91.

[0044] Furthermore, the dual-barrel material homogenizer 9 includes a portal suspension frame 96 and a control motor 97. The top of the portal suspension frame 96 is fixedly connected to the top inside the tunnel kiln. The rectangular rotating frame 92 is located below inside the portal suspension frame 96, and support pipes 921 rotatably connected to the portal suspension frame 96 are welded to the middle parts of both ends thereof. Positioning holes rotatably connected to the support pipes 921 can be opened at the bottom of the portal suspension frame 96. The control motor 97 is fixedly arranged at one end of the tunnel kiln and its output shaft is fixedly connected to one of the support pipes 921. The control motor 97 provides driving force for the rotation of the rectangular rotating frame 92. Here, the control motor 97 can be installed inside the tunnel kiln or outside the tunnel kiln, specifically depending on the temperature in the preheating zone inside the tunnel kiln.

[0045] The top of the tunnel kiln is penetrated by a spiral feeding pipe 8 opposite between the bottom and two turnover cylinders 91. A transmission auger is installed inside the spiral feeding pipe 8, aiming to convey the negative electrode material in the material cylinder outside the tunnel kiln into the two turnover cylinders 91. Among them, in the middle of the top of the portal suspension frame 96, a limiting sleeve 961 for limiting the spiral feeding pipe 8 is welded, and this limiting sleeve 961 plays a role in fixing the outer cylinder of the spiral feeding pipe 8.

[0046] Embodiment 2

[0047] Please refer to Figure 6 , and the difference from Embodiment 1 is that positioning pipes 913 are welded at both ends of the turnover cylinder 91. The positioning pipes 913 are rotatably connected to the rectangular rotating frame 92. The positioning pipe 913 at one end of the turnover cylinder 91 is fixedly connected to the first transmission gear 94. A coaxial material leveling shaft 912 is arranged inside the turnover cylinder 91. The material leveling shaft 912 is rotatably connected to the positioning pipe 913. One end of the material leveling shaft 912 is fixedly connected to a second transmission gear 9121 located outside the turnover cylinder 91. When the second transmission gear 9121 rotates, it will drive the material leveling shaft 912 to rotate. The function of the material leveling shaft 912 is to accelerate the negative electrode material in the turnover cylinder 91 to be in a uniform distribution state and reduce the accumulation time of the negative electrode material in the middle of the turnover cylinder 91. A limiting shaft 962 coaxial with the support pipe 921 is welded on the portal suspension frame 96. Specifically, the limiting shaft 962 passes through the adjacent support pipe 921 with a gap. One end of the limiting shaft 962 is fixedly connected to a limiting gear 9621 meshing with the second transmission gear 9121. During the revolution of the two turnover cylinders 91, the limiting gear 9621 will passively drive the two second transmission gears 9121 to rotate synchronously in the same direction. Two spiral blades with different spiral directions are arranged on the material leveling shaft 912 inside the turnover cylinder 91. It should be noted that the distance between the spiral blade and the inner wall of the turnover cylinder 91 is in a relatively large state.

[0048] Working principle: When in use, the kiln car 1 is driven to the bottom of the revolving drum 91, the control motor 97 is started to control the rectangular rotating frame 92 to rotate to a horizontal state, and then the rack 93 is controlled to drive the two revolving drums 91 to rotate through two transmission gears 94. When the rectangular discharge ports 911 on the two revolving drums 91 are adjacent and facing upward, the revolving drums 91 are controlled to stop rotating. Then, the external negative electrode material is introduced into the middle of the rectangular discharge openings 911 on the two rotating drums 91 through the spiral discharge pipe 8. When the negative electrode material is in the middle of the rectangular discharge opening 911 and is about to overflow, the two rotating drums 91 are controlled to rotate synchronously until their rectangular discharge openings 911 are opposite to each other. At this time, the two rotating drums 91 form a closed cavity connected by the rectangular discharge opening 911. Then, the entire rectangular rotating frame 92 is controlled to rotate back and forth. The negative electrode materials in the two rotating drums 91 will flow to each other, so that the negative electrode materials are evenly distributed in the rotating drum 91. The operation is cyclically performed in this manner, so that more negative electrode materials are injected into the rotating drum 91. When the negative electrode materials in the rotating drum 91 are not used in time, they will be in a preheating state.

[0049] When negative electrode materials need to be loaded into the kiln car 1, the two rotating drums 91 are controlled to rotate downward. At this time, the rectangular discharge port 911 opens downward, and the negative electrode materials evenly distributed in the rotating drum 91 will enter the kiln car 1. The negative electrode materials in the kiln car 1 will naturally form a uniformly filled state, and then the kiln car 1 can be controlled to enter the heating zone for processing.

[0050] After the negative electrode material is processed, the kiln car 1 is controlled to enter the top of the conveyor belt 6 in the cooling zone. At this time, the conveyor belt 6 is started. When the belt 61 is running, the dial plate 7 on it will drive one of the unloading wheels 5 to rotate. When the unloading wheel 5 rotates, the negative electrode material in its V-groove 51 will directly fall onto the belt 61, and then follow the belt 61 to move to the outside of the tunnel kiln, realizing the automatic unloading function.

[0051] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
