Description

Technical Field

[0001] This utility model relates to the field of diamond micron powder production technology, and in particular to a dry powder sampling device specifically for diamond micron powder production. Background Technology

[0002] Diamond micron powder production involves a complete process from raw material preparation, crushing and shaping, grading and purification, and testing and packaging. It processes diamond raw materials into ultrafine powder with a particle size of 1-100μm. The core objective is to ensure that the micron powder has a uniform particle size distribution, complete crystal shape, and high purity, making it suitable for polishing, grinding, precision machining and other applications.

[0003] In the existing technology, in order to ensure production quality, it is necessary to sample and test the processed dry powder during the diamond micron powder production process. However, conventional sampling devices require the sample to be transferred to a storage container after sampling with sampling tools. The transfer process requires careful handling to prevent spillage and leakage. Furthermore, the extracted dry powder is easily affected by air humidity and impurities and dust, which can affect the accuracy of subsequent testing. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the prior art by proposing a dry powder sampling device for diamond micron powder production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A dry powder sampling device for diamond micron powder production includes a base plate, a cylinder, and a piston. The base plate is fixedly connected to the upper surface of the cylinder. The piston is slidably disposed on the inner wall of the cylinder. A sampling tube is fixedly connected to the bottom of the piston. The sampling tube has graduation lines on its side wall. A fixing frame is fixedly connected to the top of the cylinder. A threaded ring is fixedly connected to the inner wall of the fixing frame. A threaded handle is threadedly connected to the inner wall of the threaded ring. An opening is provided on the inner wall of the top of the cylinder. The bottom end of the threaded handle passes through the opening and is rotatably connected to the inner wall of the top of the piston. The bottom of the sampling tube is tapered.

[0006] Preferably, a handle is fixedly connected to the side wall of the cylinder.

[0007] Preferably, the inner wall of the cylinder is provided with a guide groove, and a guide block is fixedly connected to the side wall of the piston, the guide block being slidably disposed on the inner wall of the guide groove.

[0008] Preferably, the sampling tube has an opening at the bottom, and a fixing rod is fixedly connected to the inner wall of the opening. A baffle and a torsion spring are movably sleeved on the wall of the fixing rod. One end of the torsion spring is fixedly connected to the inner wall of the fixing rod, and the other end of the torsion spring is fixedly connected to the inner wall of the baffle.

[0009] Preferably, the side of the baffle away from the fixing rod is set as a concave surface, and the sampling tube is located on the inner wall of the opening and matches the baffle.

[0010] Preferably, a sealing gasket is fixedly connected to the inner wall of the sampling tube at the opening, and the sealing gasket is pressed tightly onto the side wall of the baffle.

[0011] Compared with the prior art, this utility model provides a dry powder sampling device specifically for diamond micron powder production, which has the following beneficial effects: 1. This special dry powder sampling device for diamond micron powder production allows the operator to hold the handle and align the bottom of the sampling tube with the pile of dry diamond micron powder to be sampled. The conical design allows the sampling tube to be inserted into the dry powder more smoothly, reducing insertion resistance. By rotating the threaded handle connected to the threaded ring on the inner wall of the fixing frame, the piston slides downward on the inner wall of the cylinder. The diamond micron powder in the dry powder pile pushes the baffle at the bottom opening of the sampling tube. The baffle rotates around the fixing rod and compresses the torsion spring. At this time, the opening opens, and the diamond micron powder is pushed into the sampling tube to achieve sampling.

[0012] 2. This dry powder sampling device for diamond micron powder production can visually display the sampling amount through the scale lines on the side wall of the sampling tube. The operator can control the rising height of the piston by rotating the threaded handle as needed, thereby accurately controlling the sampling amount. When the sampling amount reaches the preset value, the threaded handle is rotated in the opposite direction, causing the piston to slide upward, the torsion spring releases its elastic potential energy, and pushes the baffle to reset.

[0013] 3. This special dry powder sampling device for diamond micron powder production achieves a seal by pressing the baffle tightly against the sealing gasket on the inner wall of the sampling tube opening, preventing dry powder leakage or the entry of external impurities during sampling and ensuring sampling purity. The side of the baffle away from the fixing rod is set as a concave surface and matches the inner wall of the sampling tube opening, further improving the sealing effect. Attached Figure Description

[0016] 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.

[0017] Reference Figure 1-3 A dry powder sampling device for diamond micron powder production includes a base plate 1, a cylinder 2, and a piston 3. The base plate 1 is fixedly connected to the upper surface of the cylinder 2. The piston 3 is slidably disposed on the inner wall of the cylinder 2. A sampling tube 4 is fixedly connected to the bottom of the piston 3. A scale line 5 is provided on the side wall of the sampling tube 4. A fixing frame 7 is fixedly connected to the top of the cylinder 2. A threaded ring 8 is fixedly connected to the inner wall of the fixing frame 7. A threaded handle 9 is threadedly connected to the inner wall of the threaded ring 8. An opening is provided on the inner wall of the top of the cylinder 2. The bottom end of the threaded handle 9 passes through the opening and is rotatably connected to the inner wall of the top of the piston 3. The bottom of the sampling tube 4 is tapered.

[0018] A handle 6 is fixedly connected to the side wall of the cylinder 2, and a guide groove is provided on the inner wall of the cylinder 2. A guide block 10 is fixedly connected to the side wall of the piston 3, and the guide block 10 is slidably disposed on the inner wall of the guide groove.

[0019] The sampling tube 4 has an opening at the bottom. A fixing rod 11 is fixedly connected to the inner wall of the sampling tube 4 at the opening. A baffle 12 and a torsion spring 13 are movably sleeved on the wall of the fixing rod 11. One end of the torsion spring 13 is fixedly connected to the inner wall of the fixing rod 11, and the other end of the torsion spring 13 is fixedly connected to the inner wall of the baffle 12.

[0020] The handle 6 on the side wall of the cylinder 2 makes it easy for the operator to hold the device, improving the convenience and stability of the sampling process. When in use, the operator holds the handle 6 and aligns the bottom of the sampling tube 4 with the pile of diamond micro powder to be sampled. The conical design allows the sampling tube 4 to be inserted into the dry powder more smoothly, reducing insertion resistance.

[0021] The threaded handle 9, connected to the threaded ring 8 on the inner wall of the rotating fixed frame 7, passes through the top opening of the cylinder 2 and is rotatably connected to the inner wall of the top of the piston 3. As the threaded handle 9 rotates, the piston 3 slides downward on the inner wall of the cylinder 2. The guide block 10 on the side wall of the piston 3 slides along the guide groove on the inner wall of the cylinder 2, providing precise guidance for the movement of the piston 3 and preventing the piston 3 from deviating, which would cause unstable pressure inside the sampling tube 4. The diamond micro powder in the dry powder pile pushes the baffle 12 at the bottom opening of the sampling tube 4. The baffle 12 rotates around the fixed rod 11 and compresses the torsion spring 13. At this time, the opening opens, and the diamond micro powder is pushed into the sampling tube 4 to achieve sampling.

[0022] The scale line 5 on the side wall of the sampling tube 4 can intuitively display the sampling amount. The operator can rotate the threaded handle 9 to control the rising height of the piston 3 as needed, thereby accurately controlling the sampling amount. When the sampling amount reaches the preset value, the threaded handle 9 is rotated in the opposite direction to drive the piston 3 to slide upward. The torsion spring 13 releases its elastic potential energy and pushes the baffle 12 to reset.

[0023] After sampling is completed, the operator holds handle 6 and moves the device above the testing container. Then, the threaded handle 9 is rotated again to make piston 3 slide downwards, opening the baffle 12 from the outside and allowing the dry powder to be discharged from the opening into the testing container, thus completing the sampling transfer. This achieves accurate, efficient, and clean sampling of diamond micro powder dry powder, which is suitable for the sampling and testing needs in the diamond micro powder production process.

[0024] To ensure sample purity, such as Figure 1-3 As shown, the side of the baffle 12 away from the fixing rod 11 is set as a concave surface. The sampling tube 4 is located on the inner wall of the opening and matches the baffle 12. The sampling tube 4 is fixedly connected to the inner wall of the opening with a sealing gasket 14. The sealing gasket 14 is pressed and set on the side wall of the baffle 12.

[0025] The baffle 12 is pressed tightly against the sealing gasket 14 on the inner wall of the sampling tube 4 opening to seal the opening, preventing dry powder leakage or external impurities from entering during the sampling process and ensuring the purity of the sample. The side of the baffle 12 away from the fixing rod 11 is set as a concave surface and matches the inner wall of the sampling tube 4 opening to further improve the sealing effect.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
