Description

Technical Field

[0001] This utility model relates to the technical field of sample dividers, specifically a sample divider for preparing chemical analysis samples. Background Technology

[0002] When preparing coal for chemical analysis, it is necessary to divide the coal into multiple samples according to particle size, and a set of dividers is usually used for sample reduction. Existing dividers come in three sizes: large, medium, and small. Sampling requires manual operation, which is time-consuming and labor-intensive. Furthermore, each size can only divide samples into two particle size ranges at a time, which limits its usability. Therefore, those skilled in the art have proposed a sample reduction divider for chemical analysis sample preparation to address the problems mentioned in the background. Utility Model Content

[0003] The purpose of this invention is to provide a sample reduction device for chemical analysis sample preparation, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A sample reduction device for chemical analysis sample preparation includes a base, on which a reduction chamber is mounted. The top and bottom of the reduction chamber are respectively provided with an inlet and an outlet. A plurality of sample frames are evenly spaced vertically within the inner cavity of the reduction chamber via a fixing frame. A rotating rod is positioned at the center of the inner cavity of the reduction chamber, passing through the middle of the sample frames. A driving component is mounted at the center of the top of the reduction chamber, and the top of the rotating rod is connected to the output end of the driving component. The portion of the rotating rod located within the sample frames is evenly spaced on the outer wall. The sample distribution frame is connected to several stirring rods. An elastic cloth ring is connected to the bottom end of the sample distribution frame. A lifting connection assembly is installed on the part of the rotating rod located at the bottom end of the sample distribution frame. A screen is connected to the lifting connection assembly. The outer perimeter of the screen is connected to the inner perimeter of the elastic cloth ring. Side discharge ports are provided on both sides of the bottom of the sample distribution frame. A closing and opening assembly is provided on the inner side wall of the sample distribution frame in contact with the side discharge ports. The outer end of the side discharge port is connected to one end of the discharge plate. The other end of the discharge plate extends to the outside of the reducing box. The screen aperture size of the screens gradually decreases from top to bottom.

[0006] As a further embodiment of this utility model: the inner sidewall of the shrink box is provided with a storage groove near the side outlet, and the closing and opening assembly includes a first telescopic member installed on the inner sidewall of the shrink box and a circular plate installed in the storage groove.

[0015] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.

[0016] Example 1: Please refer to Figures 1 to 3 A sample reduction device for chemical analysis sample preparation includes a base 1, on which a reduction chamber 2 is mounted. The top and bottom of the reduction chamber 2 are respectively provided with an inlet 3 and an outlet 4. A plurality of sample frames 6, cylindrical in shape, are evenly spaced vertically within the inner cavity of the reduction chamber 2 via a fixing frame 5. A rotating rod 13 is positioned at the center of the inner cavity of the reduction chamber 2, passing through the middle of the sample frames 6. A driving component 12 is mounted at the center of the top of the reduction chamber 2, and the top of the rotating rod 13 is connected to the output end of the driving component 12. The portion of the rotating rod 13 located within the sample frames 6... Several stirring rods 14 are connected at equal intervals on the outer wall. An elastic cloth ring 19 is connected to the bottom end of the sample dividing frame 6. A lifting connection assembly 11 is installed on the part of the rotating rod 13 located at the bottom end of the sample dividing frame 6. A screen 7 is connected to the lifting connection assembly 11. The outer periphery of the screen 7 is connected to the inner periphery of the elastic cloth ring 19. Side discharge ports 8 are provided on both sides of the bottom of the sample dividing frame 6. A closing and opening assembly 10 is provided on the inner side wall of the sample dividing frame 6 in contact with the side discharge ports 8. The outer end of the side discharge port 8 is connected to one end of the discharge plate 9. The other end of the discharge plate 9 extends to the outside of the shrinking box 2. The screen hole size of the screens 7 gradually decreases from top to bottom.

[0017] Please see Figure 1 , Figure 2 The inner wall of the shrinking box 2 is provided with a storage groove 15 near the side outlet 8. The closing and opening assembly 10 includes a first telescopic member 17 installed on the inner wall of the shrinking box 2 and a circular plate 16 installed in the storage groove 15. The bottom end of the first telescopic member 17 is connected to the top side wall of the circular plate 16 through a connecting plate 18. In this embodiment, the lifting connection assembly 11 includes a second telescopic member 20 installed on the outer wall of the rotating rod 13 and a movable sleeve 21 sleeved on the rotating rod 13. The bottom side of the movable sleeve 21 is connected to the top end of the second telescopic member 20. The upper part of the movable sleeve 21 is rotatably connected to a rotating sleeve 22. The inner circumference of the screen 7 is connected to the outer circumference of the rotating sleeve 22.

[0018] Example 2: See Figure 1 , Figure 3 Based on Embodiment 1, the inner wall of the reducing box 2 is connected to a guide plate 23 located below the sample dividing frame 6. The guide plate 23 can effectively transport the sample falling from above to the next sample dividing frame 6.

[0019] Please see Figure 1The outer wall of the shrink box 2 is equipped with a control box 24. The first telescopic member 17 and the second telescopic member 20 are both electric telescopic rods. The drive member 12, the first telescopic member 17, and the second telescopic member 20 are all connected to the control box 24 by wiring.

[0020] Working principle: During use, an appropriate amount of sample is added through the feed inlet 3. The drive component 12 drives the rotating rod 13 to rotate, which in turn drives the stirring rod 14 to rotate, thus agitating the sample. The shortening of the second telescopic component 20 causes the movable sleeve 21 to move downward, moving the sieve 7 below the side discharge port 8. At this time, the sample can fall onto the sieve 7 for screening. Samples that meet the size requirements are discharged downward into the next sample sorting frame 6. This cycle continues until the sample is discharged and collected from the discharge port 4. The sample remaining in the sample sorting frame 6 is discharged through the side discharge port 8. When the sample is discharged from outlet 8, during screening, the annular plate 16 closes the side outlet 8. During discharge, the annular plate 16 is moved upward by the first telescopic member 17, at which time the side outlet 8 opens. Then, the movable sleeve 21 is moved upward by the second telescopic member 20, moving the screen 7 to a position higher than the bottom of the side outlet 8 but not in contact with the stirring rod 14. At this time, the stirring rod 14 sweeps the sample from the screen 7 onto the elastic cloth ring 19. The sample enters the side outlet 8 along the elastic cloth ring 19 and is finally discharged and collected through the discharge plate 9.
