Description

Technical Field

[0001] This utility model relates to the field of concentrate sample processing technology, specifically to a sealed device for mixing concentrate samples. Background Technology

[0002] A concentrate sample mixing device is a specialized piece of equipment used to ensure the homogeneity of concentrate samples. It is widely used in fields such as ore processing, metallurgy, and chemical engineering where precise analysis of concentrate samples is required. Its core function is to thoroughly mix concentrate samples from different batches, with varying particle sizes or compositions, through mechanical stirring, vibration, and tumbling, thereby eliminating particle segregation and compositional inhomogeneity.

[0003] Current concentrate sample homogenizing devices generally suffer from excessive size. Their bulky design not only occupies space but also hinders portability, making them unsuitable for mobile operations in geological exploration and mining sites. During fieldwork, personnel must expend significant manpower and resources transporting the equipment, severely impacting work efficiency. Furthermore, the homogenizing efficiency of these devices needs improvement. Traditional mechanisms rely on a single stirring or vibration mode, requiring tens of minutes or even longer for homogenization even when processing small samples, making them unsuitable for time-sensitive scenarios such as rapid on-site testing and emergency analysis. Especially when dealing with trace samples or urgently needed homogenized samples, the lengthy homogenization cycle can delay testing progress, resulting in the equipment's inability to match the diverse needs of on-site operations in terms of flexibility and practicality. Utility Model Content

[0004] To solve the above-mentioned problems, this utility model proposes a closed device for mixing concentrate samples that is small in size, easy to carry, convenient for mixing small-volume samples, and has a fast mixing speed.

[0005] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is: a sealed device for mixing concentrate samples, comprising:

[0006] The cylinder has an upper cover and a lower cover at its upper and lower ends, respectively. The upper cover and the lower cover are sealed to the cylinder and are detachable.

[0007] The stirring mechanism includes a stirring shaft, stirring blades and stirring plates. The stirring shaft is rotatably connected to the inside of the upper cover and is driven by a motor fixed on the upper cover. The stirring blades and stirring plates are fixed on the side wall of the stirring shaft and are arranged in a plurality around the stirring shaft.

[0008] The dispersing assembly includes a sliding seat and a dispersing blade. The sliding seat is slidably disposed on the inner side wall of the cylinder, and the inner side wall of the cylinder is provided with a guide groove that matches the sliding seat. The dispersing blade is fixedly disposed on the sliding seat.

[0009] Furthermore, both the upper and lower covers are threaded onto the cylinder, and the inner wall is provided with a sealing ring that matches the upper and lower walls of the cylinder.

[0010] Furthermore, the side walls of the cylinder, upper cover, and lower cover are all provided with anti-slip textures.

[0011] Furthermore, the upper cover is equipped with a battery for powering the motor and a switch for controlling the motor.

[0012] Furthermore, the lower end of the stirring shaft contacts the lower cover, and the lower end of the stirring shaft is hemispherical.

[0013] Furthermore, the stirring blades are positioned near the upper and lower ends of the stirring shaft, and the stirring plate is located in the middle of the stirring shaft. There are at least two stirring blades and stirring plates of the same height, and the stirring plate is triangular.

[0014] Furthermore, there are no fewer than two sets of dispersing components, which are equidistantly distributed along the inner wall of the cylinder, and multiple dispersing blades are provided on the same sliding seat.

[0015] Compared with existing technologies, the advantages of this invention are as follows: the cylinder, upper cover, and lower cover are connected by a threaded seal, eliminating unnecessary external parts and resulting in a compact overall size. The stirring mechanism is directly integrated into the inside of the upper cover, and the motor, battery, and control switch are embedded in the upper cover structure, requiring no additional external equipment and significantly reducing space occupation. This design allows the device to be held with one hand, and the anti-slip texture on the side wall makes it easy for operators to carry to the sampling site.

[0016] For small-volume samples, the stirring blades and triangular stirring plates form a three-dimensional stirring zone inside the cylinder, while the dispersing blades are evenly distributed along the inner wall to quickly break up particle agglomerates. When the motor drives the stirring shaft to rotate at high speed, the upper and lower stirring blades and the middle stirring plate work together to shear the sample, and the dispersing components slide synchronously to break up clumps. Under these multiple actions, the sample can be uniformly mixed in a short time, which is significantly more efficient than traditional manual mixing methods. It is particularly suitable for the rapid processing of small batches of samples in the field or in the laboratory. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 3 A sealed device for mixing concentrate samples includes: a cylindrical body 1, with an upper cover 2 and a lower cover 3 at its upper and lower ends, respectively. The upper cover 2 and the lower cover 3 are sealed to the cylindrical body 1 and are detachable. Both the upper cover 2 and the lower cover 3 are threaded onto the cylindrical body 1, and their inner walls are provided with sealing rings that match the upper and lower walls of the cylindrical body 1. By tightening the threads, they engage with the sealing rings, facilitating assembly and disassembly while effectively preventing concentrate sample leakage and ensuring the device's airtightness. The side walls of the cylindrical body 1, the upper cover 2, and the lower cover 3 are all provided with anti-slip textures, which increase the friction between the operator's hands and the device, preventing slippage during opening and closing of the upper cover 2 and the lower cover 3, and during shaking of the cylindrical body 1, thus improving stability and safety during use.

[0025] Combined with appendix Figure 1 Appendix Figure 5 The stirring mechanism includes a stirring shaft 4, stirring blades 5, and stirring plates 6. The stirring shaft 4 is rotatably connected to the inside of the upper cover 2 and is driven by a motor 7 fixed on the upper cover 2. The upper cover 2 is equipped with a battery 11 that supplies power to the motor 7 and a switch 12 that controls the motor 7, so that the device does not require an external power source and can be used flexibly in various occasions. The motor 7 can be easily started and stopped by the switch, and the operation is simple. The lower end of the stirring shaft 4 contacts the lower cover 3. The lower end of the stirring shaft 4 is hemispherical, which can reduce frictional loss between the lower end of the stirring shaft and the lower cover.

[0026] Combined with appendix Figure 5 The stirring blades 5 and stirring plates 6 are both fixed on the side wall of the stirring shaft 4, and several are arranged around the stirring shaft 4. The stirring blades 5 are arranged near the upper and lower ends of the stirring shaft 4, and the stirring plates 6 are arranged in the middle of the stirring shaft 4. There are no less than two stirring blades 5 and stirring plates 6 of the same height. The stirring plates 6 are triangular. The stirring blades at the upper and lower ends and the stirring plates in the middle work together. The triangular stirring plates enhance the shear force on the sample and can mix the concentrate sample efficiently in all directions.

[0027] Combined with appendix Figure 4The dispersing assembly includes a sliding seat 8 and dispersing blades 9. The sliding seat 8 is slidably disposed on the inner wall of the cylinder 1, and the inner wall of the cylinder 1 is provided with a guide groove 10 matching the sliding seat 8. The dispersing blades 9 are fixedly disposed on the sliding seat 8. There are no fewer than two sets of the dispersing assembly, which are equidistantly distributed along the inner wall of the cylinder 1. Multiple dispersing blades 9 are provided on the same sliding seat 8, which can fully disperse agglomerated concentrate particles. Combined with the stirring mechanism, the sample is mixed more evenly, improving the mixing effect.

[0028] The specific implementation method of this utility model is as follows: Tightly screw the lower cover 3 onto the lower end of the cylinder 1. Open the upper cover 2 and pour the concentrate sample to be mixed into the cylinder 1. Align the lower end of the stirring shaft 4 with the center of the lower cover 3 and place it into the cylinder 1. Tighten the upper cover 2, ensuring a seal through the inner wall sealing ring. Press the switch 12 on the upper cover 2 to start the motor 7 powered by the battery 11. The motor 7 drives the stirring shaft 4 to rotate, causing the stirring blades 5 and stirring plates 6 on the stirring shaft 4 to rotate at high speed. The stirring blades 5 at the upper and lower ends, along with the triangular stirring plates 6 in the middle, work together to mix the sample. The stirring plates 6 shear the agglomerated sample. Simultaneously, the cylinder 1 is shaken, and the sliding seat 8 in the guide groove 10 on the inner side wall of the cylinder 1 drives the dispersing blade 9 to slide, breaking up the agglomerated concentrate particles and promoting rapid mixing. After the sample is mixed, turn off the switch 12 to stop the motor 7. Lower the cover 3 again and remove the mixed sample. Throughout the process, the anti-slip texture on the side walls of the cylinder 1, upper cover 2, and lower cover 3 prevents the device from slipping, ensuring safe operation.
