[0016] 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 embodiments described 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.

[0017] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0018] Reference Figure 1-2 The utility model provides a high-temperature sampling device for lithium battery materials, including a sampling body 1, the sampling body 1 includes a horizontally arranged sampling cylinder 101 and a vertically arranged conveying cylinder 102, the conveying cylinder 102 is connected to the middle of the sampling cylinder 101, a sampling block 2 is slidably connected in the sampling cylinder 101, the sampling block 2 is located at one end of the sampling cylinder 101, a sampling groove 3 is provided on the side wall of the sampling block 2, the other end of the sampling cylinder 101 is fixedly connected to a mounting cylinder 4, the mounting cylinder 4 is connected to the conveying cylinder 102, a control component for controlling the movement of the sampling block 2 is installed in the mounting cylinder 4, a water tank 5 is provided below the sampling cylinder 101, and the conveying cylinder 102 is arranged through the water tank 5. The control component controls the movement of the sampling block 2, so that the sampling block 2 moves into the reactor and uses the sampling slot 3 to receive the material. When the material is full, the control component controls the sampling block 2 to be retracted and flipped when the sampling slot 3 moves to the top of the conveying cylinder 102, so that the sampled material falls into the conveying cylinder 102, is cooled by the water tank 5, and is collected, thereby completing the sampling operation.

[0019] A further optimized solution is that the control component includes a receiving groove 6 provided on the side wall of the mounting tube 4, a copper nut 7 rotatably connected in the receiving groove 6, one end of the copper nut 7 is located in the receiving groove 6, and the other end of the copper nut 7 penetrates the side wall of the mounting tube 4 and is located outside the mounting tube 4. A screw 8 is provided in the mounting tube 4, one end of the screw 8 is located in the sampling tube 101 and is fixedly connected to the sampling block 2, the other end of the screw 8 penetrates the copper nut 7 and is located outside the mounting tube 4, and the screw 8 is threadedly connected to the copper nut 7; a limit assembly is installed on the inner wall of the sampling tube 101 to limit the rotation of the sampling block 2. The limit assembly limits the rotation of the sampling block 2, so that the copper nut 7 drives the screw 8 to slide horizontally during the rotation process, thereby driving the sampling block 2 into or out of the reactor, thereby achieving control of the sampling block 2.

[0020] As a further optimization solution, the limiting assembly includes a limiting pin 9 fixedly connected to the inner wall of the sampling tube 101. The side wall of the sampling block 2 is provided with a limiting groove 10 along its axial direction. The limiting pin 9 is located at the end of the limiting groove 10 close to the screw rod 8 and slides in cooperation with the limiting groove 10. The sampling block 2 is provided with an arc groove 11, one end of which is connected to the end of the limiting groove 10 away from the screw rod 8. The arc groove 11 is located on the side of the sampling slot 3. By cooperating with the limiting pin 9 and the limiting groove 10, the copper nut 7 can only drive the screw rod 8 to move horizontally during rotation, thereby limiting the rotation of the sampling block 2. When the limiting pin 9 moves to the arc groove 11, the copper nut 7 rotates, driving the screw rod 8 to rotate, thereby ensuring that the material in the sampling slot 3 falls into the conveying tube 102.

[0021] In a further optimized solution, the arc groove 11 is located in an arc of 180°, ensuring that the sampling block 2 can rotate 180°, so that the arc groove 11 moves from an upward state to a state facing the conveying cylinder 102, allowing the material to fall into the conveying cylinder 102.

[0022] To further optimize the solution, a ball valve 12 is installed at the bottom of the conveying cylinder 102. This facilitates the control of the discharge of the conveying cylinder 102 so that the staff can take out the sample when needed.

[0023] Further optimizing scheme, the copper nut 7 is positioned at one end outside the installation cylinder 4 and is fixedly connected with a hand wheel 13. By installing the hand wheel 13, it is convenient to control the rotation of the copper nut 7.

[0024] To further optimize the solution, a water inlet and a water outlet are provided on the water tank 5, and a through hole is provided in the middle of the water tank 5 for the conveying cylinder 102 to pass through. The material in the conveying cylinder 102 is cooled by the water tank 5, which is convenient for observation and detection of the sample.

[0025] To further optimize the solution, the screw rod 8 includes a threaded section and a smooth section. The threaded section cooperates with the copper nut 7, the smooth section is fixedly connected to the sampling block 2, and a stuffing cover is slidably connected to the smooth section. The stuffing cover is fixedly installed in the mounting tube 4. The stuffing cover can support the middle part of the screw rod 8 to prevent it from deformation, thereby increasing the service life of the screw rod 8.

[0026] The working process of the present invention is as follows: turn the handwheel 13, the handwheel 13 drives the copper nut 7 to rotate. Since the copper nut 7 is threadedly matched with the screw rod 8, and since the limit pin 9 is in the horizontally arranged limit groove 10 at this time, the screw rod 8 cannot rotate and can only slide in the horizontal direction, thereby driving the sampling block 2 to move into the reactor, and the material is received through the sampling groove 3. After it is full, turn the handwheel 13 in the opposite direction of the previous rotation, and the handwheel 13 drives the sampling block 2 to retract through the copper nut 7. When the limit pin 9 moves to the arc groove 11, continue to turn the handwheel 13. At this time, the limit groove 10 is no longer limited by the limit pin 9, thereby causing the screw rod 8 to drive the sampling block 2 to rotate 180 degrees, so that the sampling groove 3 is facing the conveying cylinder 102, so that the collected material falls into the conveying cylinder 102, and is cooled by the water tank 5 from a high temperature environment of 600 degrees to below 80 degrees, and then collected to complete the sampling.

[0027] In the description of the present invention, it should be understood that the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present invention.

[0028] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements to the technical solutions of the present invention made by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
