Description

Technical Field

[0001] This invention relates to the field of powder or granular material production technology, and in particular to a positive pressure material sampling device. Background Technology

[0002] After sintering, the lithium iron phosphate powder is sent to an air jet mill for crushing and classification. The particle size of the classified material needs to be sampled and analyzed promptly for monitoring. However, because the air jet mill is a positive pressure system and lacks a sampling device (only a φ64 quick-connect clamp interface is provided at a suitable location), proper sampling is not possible. Despite attempts to select several existing sampling devices, a suitable one has not been found due to factors such as the significant risk of magnetic particle introduction and unsuitable installation dimensions. Therefore, a positive pressure material sampling device needs to be developed to address these issues. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide a novel positive pressure material sampling device, which can realize positive pressure online sampling of materials in the air jet mill classification and crushing system.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A positive pressure material sampling device includes a quick-lock connector, a sampling spoon, and a handle. The sampling spoon includes an insertion part, a loading part, and a connecting part. The insertion part is located inside the quick-lock connector and can slide relative to the quick-lock connector. The connecting part is fixedly connected to one end of the handle. The loading part is used to hold material. The sampling spoon and the handle are provided with multiple sealing grooves. A sealing ring is installed in each sealing groove. The material to be sampled in the pressurized system is taken out by the alternating sealing of multiple sealing rings.

[0005] Furthermore, the quick-release connector, sampling spoon, and handle are made of nylon material.

[0006] Furthermore, the quick-release connector is fixed by a quick-release clamp installed on the pressurized system to be sampled.

[0007] Furthermore, the connection between the connecting part and one end of the handle is a threaded connection.

[0008] Furthermore, the end of the protruding part of the sampling spoon is provided with a boss to prevent the sampling spoon from being pulled out of the quick-release connector during the sampling process.

[0009] Furthermore, the number of sealing grooves and sealing rings is five, wherein the first sealing ring is located at the end of the insertion part of the sampling spoon, the second and third sealing rings are located at both ends of the filling part of the sampling spoon, and the fourth and fifth sealing rings are located on the handle.

[0010] Furthermore, two sealing rings are always in working condition during the material handling process.

[0011] Furthermore, the sealing ring is a silicone O-ring.

[0012] Furthermore, the quick-connect connector has chamfered edges at both ends.

[0013] The beneficial effects of this invention are: 1) The implementation of the positive pressure material sampling device of the present invention has successfully solved the problem of sampling difficulty, and the sampling process is convenient, fast and labor-saving; 2) The positive pressure material sampling device of the present invention uses the alternating sealing of several O-rings to cleverly remove the material in the pressurized system without causing powder leakage or spraying. 3) Since the positive pressure material sampling device of the present invention is made entirely of non-metallic materials, the risk of magnetic particle introduction is almost zero.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] like Figure 1As shown, one embodiment of the present invention provides a novel positive pressure material sampling device, mainly composed of three parts: a quick-release connector 10, a sampling spoon 20, and a handle 30, all made of nylon material, minimizing the possibility of magnetic foreign matter generation. The quick-release connector 10 is as follows... Figure 2 As shown, the sampling spoon 20 Figure 3 As shown, the handle 30 is as follows Figure 4 As shown. The quick-release connector 10 is designed based on a pre-reserved quick-release clamp interface with an inner diameter of φ64, and is fixed by the quick-release clamp 41 on the pressure system 40 to be sampled. The quick-release clamp 41 is as follows. Figure 5 As shown.

[0024] The sampling spoon 20 includes an extension portion 21, a loading portion 22, and a connecting portion 23. The extension portion 21 is located within the quick-release connector 10 and is slidable relative to the quick-release connector 10. The loading portion 22 is an open cavity for holding material. The connecting portion 23 has external threads and is fixedly connected to the internal thread 31 at one end of the handle 30. A boss 211 is provided at the end of the extension portion 21 of the sampling spoon 20 to prevent the sampling spoon 20 from being pulled out of the quick-release connector 10 during the pulling of the sampling device.

[0025] To ensure good sealing performance of the positive pressure material sampling device of this invention, five sealing grooves are designed on the sampling spoon 20 and handle 30 for installing five silicone O-rings. Figure 6 As shown, the first sealing ring 51 is located at the end of the insertion part 21 of the sampling spoon 20, the second sealing ring 52 and the third sealing ring 53 are located at both ends of the loading part 22 of the sampling spoon 20, and the fourth sealing ring 54 and the fifth sealing ring 55 are located on the handle 30. Two sealing rings are always in working condition during the material extraction process. Through the alternating sealing of these five sealing rings, the material in the pressurized system is smoothly extracted without powder leakage or spraying. Simultaneously, to ensure that the sealing rings are smoothly compressed when entering the working state during the pushing and pulling of the sampling device, chamfered edges 11 are used at both ends of the quick-release connector 10, such as... Figure 7 As shown. Figure 8 This is a schematic diagram of the positive pressure material sampling device being inserted into a pressurized system to collect material.

[0026] Preferably, the positive pressure material sampling device of the present invention is made entirely of non-metallic materials to reduce the risk of magnetic particle introduction.

[0027] The working principle of this invention is as follows: When the sampling device is fully pushed into the pressurized system, the material to be sampled falls into the sampling spoon under gravity. By pulling the handle, the material in the sampling spoon can be smoothly brought out. After the handle is fully pulled out, rotating the handle 180 degrees will pour the material into a pre-prepared sampling cup or sampling bag, and this process is repeated. Because the sampling device of this invention is designed with 5 silicone O-rings, two of the O-rings will always be in working condition regardless of the device's position. Therefore, even with a high positive pressure in the pressurized system, there will be no powder leakage or spraying during the entire sampling process.

Those skilled in the art will understand that various substitutions, changes, and modifications are possible without departing from the spirit and scope of the present invention.
