Description

Technical Field

[0001] This application relates to the technical field of sample reduction preparation, and more particularly to a reduction device in the process of preparing bulk material samples. Background Technology

[0002] Sample reduction is a step in sample processing, such as in chemical analysis. It involves dividing a sample, crushed to a certain particle diameter, into several portions of equal reliability, or reducing the size of the original sample before processing or crushing. The purpose of sample reduction is to reduce the workload of subsequent crushing or the amount of original sample transported, thus accelerating sample processing while ensuring sample reliability. Before each reduction, the sample must be thoroughly mixed. The weight of the reduced sample must be greater than the minimum reliable weight required for the given particle diameter.

[0003] Existing sample reduction methods include manual reduction methods and fully automated machine reduction methods. Manual reduction methods have the following shortcomings:

[0004] 1. Reduction is the most critical step in the preparation of bulk samples. It is a process of dividing the sample into representative parts to reduce the sample quantity. Existing manual reduction methods have a great impact on the precision of sample preparation.

[0005] 2. Manual reduction methods involve more human interference, have higher operational standards, and involve more human intervention, resulting in lower reduction precision.

[0006] 3. The manual mesh reduction method requires a high level of skill, involves complicated steps, is difficult to control the reduction amount, has low reduction accuracy, and is inefficient. Summary of the Invention

Transmission shaft 11 drives support frame 4 to rotate, which in turn drives the splitter body 7 on support frame 4 to rotate.

[0078] This application provides a sample reduction device for bulk material sampling, the specific scheme of which is as follows: Based on the requirements of the grid reduction method, a flipping component suitable for sample grid reduction below 3mm is designed to achieve sample reduction in one step, improving reduction efficiency. Specific scheme: A stainless steel plate is prepared as a sampling plate, and 20 holes are evenly cut out. Twenty 304 stainless steel tubes of the same length matching the hole diameter are used as sampling tubes 22, passed through the holes, and welded to the stainless steel plate to form a reduction cutter. The length of the steel tubes of the reduction cutter is equal to the inner height of the sample tray 21, ensuring that after the reduction cutter is inserted into the sample tray 21, the stainless steel tubes are tightly against the bottom of the sample tray 21, and the steel plate is tightly fitted against the edge of the sample tray 21 to prevent sample spillage. A sample collector 23 with a receiving drawer 24 is placed on top of the reduction cutter, ensuring that the sample collector 23 and the reduction cutter are tightly fitted. The main body of the reduction device consists of three parts: the sample tray 21, the sampling tubes 22, and the sample collector 23. Place the reducing body on the support frame 4 of the flipping device. Secure the pressure plate 6 and baffle 9 to the reducing body using the clips 8. Turn the handle 15; the axial force is transmitted via the gearbox 14, coupling 13, and drive shaft 11 to the support frame 4 supported by the flipping bearing 2. The support frame 4 will then rotate the entire reducing body 7 180°. Due to gravity, the sample in the reducing cutter's pipe will flow into the receiving drawer 24 of the sample collector 23. Pull out the receiving drawer 24 to obtain the reduced sample. Flip the cutting reducing device 180° back to its initial position, remove the sample tray 21, reducing cutter, and sample collector 23, and discard or retain any remaining sample in the sample tray 21. This achieves the purpose of quantitative sample reduction.

[0079] Based on the sample preparation and testing conditions, the base 1 and support frame 4 of this application are designed to be made of galvanized square tubing, and the main body 7 of the divider is made of 304 stainless steel.

[0080] This application provides a reduction device for bulk material sampling, the specific working process of which is as follows:

[0081] Operating steps: 1. In Figure 2 In the process, after mixing the sample to be reduced, spread it evenly in the sample tray 21 and flatten it with a flat plate of appropriate size; insert the reduction cutter into the sample tray 21 from top to bottom, and evenly select 20 samples to be taken; cover with the sample collector 23, ensuring it is in close contact with the reduction cutter. 2. In Figure 1In the process, the reducing body 7 is placed on the support frame 4 of the flipping assembly; the pressure plate 6 is rotated along the first hinge 5 to cover the reducing body 7; the baffle 9 is rotated along the second hinge 10 to a position perpendicular to the support frame 4, and the pressure plate 6 and the baffle 9 are secured with the buckle 8, simultaneously pressing the reducing body 7. 3. By rotating the handle 15, the axial force is transmitted to the support frame 4 through the gearbox 14, coupling 13, and drive shaft 11; the support frame 4 drives the reducing body 7 to flip 180° along the flipping bearing 2 and drive bearing 12. 4. After flipping, Figure 2 The 20 samples in the pipe of the reduction cutter flow into the receiving drawer 24 in the sample collector 23. The receiving drawer 24 is pulled out to obtain the reduced sample. The device is rotated 180° to return to the original position. The sample tray 21, reduction cutter, and sample collector 23 are removed. The remaining sample in the sample tray 21 is discarded or kept for future reference, thereby achieving the purpose of sample reduction at a fixed ratio.
