Description

Technical Field

[0001] This utility model relates to the field of graphite sampling technology, and in particular to an automated sampling device for finished graphite products. Background Technology

[0002] Lithium-ion battery anode materials are typically made from graphite raw materials processed in a graphitization furnace. During production, the finished graphite product needs to be sampled and analyzed to determine if it meets standards. A sampling device is required for graphite sampling, such as the one disclosed in patent CN212363682U. In use, the handle is held to insert the sampling tube into the graphite raw material for sampling. The tip of the sampling tube is then aligned with the sample bottle. The other hand is engaged in a slot in a disc-shaped block and pushed forward. The forward tilt angle of the disc-shaped block also moves forward, removing the graphite adhering to the outer wall of the sampling tube. The removed graphite falls into a collection tank for collection. Simultaneously, the disc-shaped block, through a connecting block, drives a circular baffle to push the graphite inside the sampling tube into the sample bottle. This not only facilitates the discharge of graphite from the sampling tube into the sample bottle but also collects the graphite adhering to the outer wall of the sampling tube, ensuring a safe operating environment for the operator.

[0003] It is evident that the above-mentioned sampling device is cumbersome to operate, requires manual operation, and has low sampling efficiency, thus requiring further improvement. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model discloses an automated sampling device for finished graphite products, including a sampling tube, an execution unit, a sealing component, and a sample bottle. The sampling tube has a first quick-release connector at its front end, the execution unit is located at the rear end of the sampling tube, the sealing component is movably disposed inside the sampling tube and is connected to the execution unit via transmission, a discharge tube is located below the sampling tube at the rear side of the first quick-release connector, the sample bottle is located at the lower end of the discharge tube, and the sealing component can reciprocate at the connection between the sampling tube and the discharge tube under the drive of the execution unit.

[0005] Furthermore, the sealing assembly includes a piston plate and a sealing sleeve. The piston plate is connected to the push rod of the actuation unit, and the sealing sleeve is disposed on the outside of the piston plate and is movably connected to the inner wall of the sampling tube.

[0006] Furthermore, an exhaust valve is provided above the sampling tube at a position behind the first quick-release connector.

[0007] Furthermore, the execution unit is connected to the rear end of the sampling tube via a flange.

[0008] Furthermore, the sample vial is connected to the discharge tube via a second quick-release connector.

[0009] Furthermore, the sample bottle is provided with a detachable end cap at the lower end.

[0010] Furthermore, the execution unit is a cylinder, a hydraulic cylinder, an electric actuator, or a linear module.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The automated sampling device for finished graphite products of this invention uses an execution unit to drive a sealing component to reciprocate within the sampling tube, thereby opening or closing the connection between the sampling tube and the discharge tube. When the connection is open, the sample from the graphite production equipment can enter through the sampling tube and then through the discharge tube into the sample bottle, thus achieving automatic sampling of graphite. Compared with the traditional manual sampling method, this simplifies the sampling process and improves sampling efficiency. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0020] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0021] In the description of the embodiments, unless otherwise expressly specified and limited, the terms "set," "connect," etc., should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or a connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] like Figure 1 As shown, the automated sampling device for finished graphite products in this embodiment includes a sampling tube 1, an execution unit 2, a sealing component 3, and a sample bottle 4. The front end of the sampling tube 1 is provided with a first quick-release connector 5. The execution unit 2 is connected to the rear end of the sampling tube 1 through a flange 6. The sealing component 3 is movably disposed inside the sampling tube 1 and is connected to the execution unit 2 via a transmission connection. A discharge pipe 7 is provided below the sampling tube 1 at the position behind the first quick-release connector 5. The sample bottle 4 is connected to the discharge pipe 7 through a second quick-release connector 8. A detachable end cap 9 is provided at the lower end of the sample bottle 4. An exhaust valve 10 is provided above the sampling tube 1 at the position behind the first quick-release connector 5.

[0023] Among them, the execution unit 2 can adopt the linear drive method commonly used in the field, such as a cylinder, hydraulic cylinder, electric actuator or linear module; the first quick-release connector 5 and the second quick-release connector 8 can adopt quick-release buckle, quick-release pipe clamp or other structures.

[0024] When it is necessary to clean sample vial 4, the removable end cap 9 can be removed to clean sample vial 4.

[0025] like Figure 2 As shown, the sealing assembly 3 includes a piston plate 31 and a sealing sleeve 32. The piston plate 31 is connected to the push rod 21 of the execution unit 2. The sealing sleeve 32 is placed on the outside of the piston plate 31 and is movably connected to the inner wall of the sampling tube 1. Under the drive of the execution unit 2, the sealing sleeve 32 can reciprocate at the connection port 11 between the sampling tube 1 and the discharge tube 6, thereby realizing the opening and closing of the connection port 11.

[0026] In use, the sampling device is first connected to the discharge port pipe of the production equipment through the first quick-release connector 5. Then, the execution unit 2 drives the sealing component 3 to move backward in the sampling tube 1, opening the connecting port 11, so that the graphite enters the sampling tube 1 along the discharge port pipe and enters the sample bottle 4 through the discharge pipe 6.

[0027] In addition, the execution unit 2 can be used in conjunction with a timing system to set the sampling interval and time as needed, thereby achieving automatic sampling. Compared with the traditional manual sampling method, this simplifies the sampling process and improves sampling efficiency.
