[0002] Currently, the preparation of powder samples is a crucial prerequisite for ensuring the accuracy and representativeness of test data. Traditional sample preparation processes typically involve two key steps: first, thoroughly grinding the parent sample using pulverizing equipment to obtain powder with the required particle size; second, using a powder divider to proportionally reduce or equalize the powder, thereby obtaining representative subsamples. To ensure uniformity of sample division and reduce deviations, multiple devices are required to work together, such as weighing devices, pulverizing devices, and dividing devices. Multi-step, multi-equipment operation has become the norm in the industry. However, this multi-equipment, multi-process sample division method increases the frequency of manual intervention and handling, easily increasing labor costs and introducing human error, and also results in low production efficiency.

[0067] The present application will be further described in detail below with reference to the accompanying drawings.

[0068] Example 1

[0069] like Figures 1-9As shown in the figure, this application discloses an integrated powder sample preparation and dispensing device, including a quantitative conveying device 1, a power unit 2, and a dispensing device 3. It also includes a housing 4, with the quantitative conveying device 1 positioned above the housing 4, the power unit 2 located inside the housing 4, and the dispensing device 3 installed on one side of the housing 4.

[0070] The quantitative conveying device 1, having an inlet 171 and an outlet 141, is configured to weigh materials and convey them outward at a set rate; specifically, as shown... Figures 3-5 As shown, the quantitative conveying device 1 includes a fixed base 11, which is fixed to the surface of the box. A weighing sensor 12 is installed on the fixed base 11, and a support base 13 is installed at the other end of the weighing sensor 12. A feeding box 14 is fixed on the support base 13. A motor 15 is installed outside the feeding box 14. The motor 15 is a servo motor. The shaft end of the motor 15 extends into the feeding box 14 and is connected to a conveying wheel 16. A feeding hopper 17 is connected to the top of the feeding box 14. A protective cover 18 is installed outside the fixed base 11. The feeding port 171 is located on the feeding hopper 17, and the discharging port 141 is located below the feeding box 14. In this example, after the feed hopper 17, discharge box 14, motor 15, conveyor wheel 16 and support base 13 are connected to form an integral structure, they are installed at one end of the weighing sensor 12. The weight of the material fed into the feed hopper 17 can be detected by the weighing sensor 12. The conveyor wheel 16 has toothed grooves in the circumferential direction, and the outer diameter of the conveyor wheel 16 is close to the inner wall of the working cavity of the discharge box 14. The material is conveyed only when the conveyor wheel 16 is rotated. After the motor 15 drives the conveyor wheel 16 to rotate, it can work with the weighing sensor 12 to monitor the amount of falling material in real time, so as to achieve the effect of accurate feeding.

[0071] In addition, in other embodiments, the material can be conveyed by a screw conveyor, which can also achieve precise quantitative feeding.

[0072] The power unit 2 has its feed end connected to the discharge port 141 of the quantitative conveying device 1. The discharge end is set horizontally and is configured to grind the material and drive the ground powder to be conveyed outward at a set speed in the horizontal direction. In this example, the power unit 2 is a cyclone pulverizer, specifically a hammer cyclone mill. The hammer cyclone mill uses a motor and belt drive installed inside the housing 4 to pulverize the material. Its upper feed end is located below the discharge port 141, and to facilitate weighing the material, the feed end and the discharge port 141 do not contact each other. Its discharge end is arranged horizontally, allowing the powder to be conveyed outward in the horizontal direction at a specified speed.

[0073] In addition, in other embodiments, the power unit 2 may also be an ultracentrifugal mill with airflow; or a combination device of blade mill with post-stage air extraction, a combination device of blade mill with pre-stage air blowing, a combination device of disc mill with post-stage air extraction or pre-stage air blowing, etc.

[0074] The dispensing device 3 includes a first dispensing cylinder 31. A feed side pipe 311 is provided above the first dispensing cylinder 31, and the feed side pipe 311 is tangentially connected to the first dispensing cylinder 31, with their inner cavities communicating. The feed side pipe 311 is connected to the outlet end of the power device 2, causing the powder to rotate tangentially after entering the first dispensing cylinder 31 and gradually descend during rotation. At least two sample collection components 32 are installed on the first dispensing cylinder 31. The sample collection components 32 can be canister-shaped, or in other embodiments, bag-shaped.

[0075] In this example, a first air outlet pipe 33 is installed at the top middle position of the first dispensing cylinder 31. The lower end of the first air outlet pipe 33 extends into the interior of the first dispensing cylinder 31 and is lower than the position of the feed side pipe 311. The upper end of the first air outlet pipe 33 extends outward toward the top of the powder cylinder, and a filter screen 34 is connected to the upper end of the first air outlet pipe 33. That is, the working principle of a cyclone separator is adopted. The high-speed airflow will drive the powder to make a circumferential centrifugal motion inside the first dispensing cylinder 31. At the same time, under the influence of gravity, the powder will spiral down along the inner wall of the first dispensing cylinder 31.

[0076] In this example, the lower end of the first dispensing cylinder 31 has a conical structure. In other embodiments, the first dispensing cylinder 31 can also be a straight cylinder structure, which can also satisfy the effect of split spiral falling.

[0077] In this example, a sampling tube 312 is installed on the lower side wall of the first dispensing cylinder 31. The number of sampling tubes 312 can be set differently according to needs. In this example, there is one sampling tube 312. The inner cavity of the sampling tube 312 is connected to the inner cavity of the first dispensing cylinder 31. The sample collection element 32 is located at the end of the sampling tube 312. Specifically, the sample collection element 32 is directly installed at the end of the sampling tube 312, and a valve 35 is installed on the sampling tube 312. The valve 35 can be a butterfly valve or a baffle structure, used to control the amount of powder passing through the sampling tube 312 per unit time to achieve quantitative sampling. During operation, the powder moves spirally downward in the first dispensing cylinder 31. When it moves to the position of the sampling tube 312, some of the powder will pass through the sampling tube 312 and enter the sample collection element 32.

[0078] In this example, a sample collection device 32 is installed at the lower end of the first dispensing cylinder 31. More specifically, a receiving ring 36 is installed at the lower end of the first dispensing cylinder 31. A partition 361 is installed inside the receiving ring 36, which divides the internal space of the receiving ring 36 into multiple cavities. A discharge pipe 37 is connected to the bottom of each cavity. The sample collection device 32 is located at the end of the discharge pipe 37. In this embodiment, the partitions 361 are evenly distributed around the center of the receiving ring 36 and fixed inside the receiving ring 36. There are three partitions 361, which can be used to evenly divide the powder into three equal parts.

[0079] It is understood that in other embodiments, the number of partitions 361 may be set to different numbers.

[0080] It is also understood that in other embodiments, the partition 361 is movably connected to the inside of the receiving ring 36. For example, the partition 361 can be connected to the shaft at the center of the receiving ring 36 by a bearing, so that the partition 361 can rotate around its central axis, thereby changing the included angle between two adjacent partitions 361. This is configured to allow the size of different cavities to be adjusted according to actual needs, for collecting samples of a specific weight in different sample collection components 32. In this case, the feed pipe 37 below the partition 361 can be made of a soft material.

[0083] Example 3

[0084] like Figures 11-12 As shown, the difference between this embodiment and the above-mentioned embodiment two is only that: in this embodiment, the end of the sampling tube 312 is arranged horizontally and connected to a second dispensing cylinder 38. The second dispensing cylinder 38 is tangent to the sampling tube 312 and their inner cavities are interconnected. The sample collection component 32 is installed at the lower end of the second dispensing cylinder 38. A second air outlet pipe 381 is installed above the second dispensing cylinder 38. One end of the second air outlet pipe 381 extends into the second dispensing cylinder 38 and its port is lower than the end of the sampling tube 312. The other end of the second air outlet pipe 381 extends outward from the top of the second dispensing cylinder 38, and a valve 35, which is a butterfly valve, is installed on the second air outlet pipe 381. In this example, the combination of the second dispensing cylinder 38 and the second air outlet pipe 381 allows the airflow to quickly carry the powder into the second dispensing cylinder 38, achieving the effect of rapid sample dispensing.

There are three partitions 361, which can be used to evenly divide the powder into three equal parts.
