Description

Technical Field

[0001] This utility model relates to the field of powder sampling devices, and in particular to an online sampling device. Background Technology

[0002] In the powder manufacturing industry, particle size is one of the key indicators for measuring powder quality, directly affecting the performance and application effect of the final product. Therefore, particle size testing of powder is crucial during the powder manufacturing process. However, in traditional powder manufacturing equipment, sampling and testing of powder at any stage of powder production, whether in the initial stage or at any point during powder production, often requires interrupting the normal production process. This necessitates pausing the equipment, having operators open relevant parts of the equipment (such as silos and pipe interfaces) to manually collect powder samples, and then resealing the equipment and restarting production. Each sampling operation requires stopping the machine, resulting in significant time commitment and a substantial extension of the entire testing cycle. The process of stopping and opening the equipment for sampling not only reduces production efficiency but also causes additional wear and tear on the equipment. Furthermore, the direct contact between operators and powder during manual sampling poses health and safety risks. Utility Model Content

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: an online sampling device, including a hopper, a sampling tube is provided on one side of the hopper, the sampling tube passes through the hopper, the sampling tube is a hollow pipe structure, one end of the sampling tube is a sampling end, and the other end is a discharging end; the sampling end is located inside the hopper, and a sampling port is provided at the end of the sampling end, the discharging end is located outside the hopper, and a discharging port is provided at the discharging end, and a sampling bottle is connected to the discharging port; a sampling cylinder is provided on one side of the discharging end, a sampling rod is provided on the movable end of the sampling cylinder, a pair of push plates are provided on the sampling rod, the push plates are arranged one in front of the other on the sampling rod, and a sampling groove is formed between the push plates.

[0005] Preferably, when the sampling cylinder extends, the sampling slot position corresponds to the sampling port, and when it retracts, the sampling slot position corresponds to the discharge port.

[0006] Preferably, the end of the sampling tube is configured as an open structure, and one of the push plates on the sampling rod is aligned with the opening position at the end of the sampling tube when the sampling cylinder extends.

[0007] Preferably, the push plate is also provided with a sealing ring.

[0008] The beneficial effects of this utility model are: by setting up the sampling tube, sampling can be completed automatically without stopping the machine during the powder sampling process, which significantly improves the sampling efficiency and reduces equipment downtime.

Detailed Implementation

[0011] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0012] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0013] according to Figures 1-3 As shown, an online sampling device includes a hopper 1. A sampling tube 2 is provided on one side of the hopper 1 and passes through the hopper 1. The sampling tube 2 is a hollow pipe structure. One end of the sampling tube 2 is a sampling end 3, and the other end is a discharge end 4. The sampling end 3 is located inside the hopper 1 and has a sampling port 31 at its end. The discharge end 4 is located outside the hopper 1 and has a discharge port 41 at its position. A sampling bottle 42 is connected to the discharge port 41. A sampling cylinder 5 is provided on one side of the discharge end 4. A sampling rod 6 is provided on the movable end of the sampling cylinder 5. A pair of push plates 61 are provided on the sampling rod 6, one in front of the other, forming a sampling groove 62 between the push plates 61.

[0014] When the sampling cylinder 5 extends, the sampling slot 62 corresponds to the sampling port 31; when it retracts, the sampling slot 62 corresponds to the discharge port 41.

[0015] The sampling tube 2 is configured with an open structure at its end, and one of the push plates 61 on the sampling rod 6 is aligned with the opening position at the end of the sampling end 3 when the sampling cylinder 5 is extended.

[0016] The push plate 61 is also equipped with a sealing ring 63 to reduce the leakage of powder during the sampling and transfer process.

[0017] In practical application, the sampling tube 2 can be installed not only on the hopper 1, but also on other locations where powder flows, such as on the pipeline for conveying powder. In the initial state, the sampling cylinder 5 will remain extended, so that the sampling groove 62 corresponds to the sampling port 31. During the flow of powder in the hopper 1, the powder will enter the sampling groove 62 through the sampling port 31. Then, the sampling cylinder 5 will retract, so that the sampling groove 62 reaches the discharge port 41 position, transferring the powder to the discharge port 41 position. Then, the powder will enter the sampling bottle 42 through the discharge port 41. Then, the sampling cylinder will extend again. During the extension process, the push plate 61 will also retract the sampling rod 6, and the powder that enters the sampling end 3 through the sampling port 31 will be pushed out from the opening position at the end of the sampling end 3. Then, the sampling bottle 42 will be removed to complete the sampling.

[0018] This design is ingenious. By setting up the sampling tube, the powder sampling process can be completed automatically without stopping the machine, which significantly improves sampling efficiency, reduces equipment downtime, avoids the impact of downtime on production and equipment, eliminates manual operation, and reduces safety hazards.

[0019] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
