Description

Technical Field

[0001] This utility model belongs to the field of sampling equipment, specifically, it relates to a simple automatic reduction device for powdery materials. Background Technology

[0002] In the testing and sample preparation of powdered materials, a large quantity of material needs to be weighed, while only a small amount is required for testing. Therefore, it is necessary to reduce the quantity of material to smaller, equal portions. This reduction involves homogenizing or approximately homogenizing the large quantity of material into multiple smaller portions to facilitate repeated testing. Improper reduction can lead to significant discrepancies between the test data and the actual data, affecting the accuracy of the test. Conventional reduction often involves manual, multiple quartering operations. This method is time-consuming and cumbersome, especially for powdered materials, as it generates a large amount of dust, creating a poor working environment that is unfavorable for personnel.

[0003] To address this issue, we propose a simple automatic reduction device for powdery materials. Utility Model Content

[0004] To address the aforementioned problems in the existing technology, the purpose of this utility model is to provide a simple automatic reduction device for powdered materials to solve these problems. To solve the above problems, the technical solution adopted by this utility model is as follows: A simple automatic material reduction device includes a cylindrical body with multiple hoppers at its bottom. The inner wall of the cylindrical body, from top to bottom, comprises a first dispersion layer, a first funnel, a second dispersion layer, and a second funnel. The first dispersion layer consists of multiple layers of steel rods, each layer comprising multiple parallel steel rods. The steel rods in adjacent layers intersect each other axially in a plane. The second dispersion layer includes a distribution plate and a buffer platform. The buffer platform has a conical buffer section at its top and a cylindrical connecting section at its bottom. The distribution plate is fixedly fitted onto the side wall of the connecting section and consists of multiple dividing blades arranged circumferentially around the connecting section. Each dividing blade has a plate-like inner end and a forked opening at its outer end. A distribution rod is also provided at the center of the bottom of the cylindrical body to reduce the material. The multiple hoppers are located below the second funnel and separated by the distribution rod, arranged circumferentially around the vertical axis of the cylindrical body.

[0005] Furthermore, the slope of the sidewall of the buffer section continuously becomes steeper from top to bottom.

[0006] Furthermore, the outer edge of the bottom end of the buffer portion corresponds to the connection between the inner and outer ends of the separator leaf, the top of the connecting portion exposes the material distribution plate, and the exposed shaft section is circumferentially concave inward, with the concave depth corresponding to the inner end length of the separator leaf.

[0007] Furthermore, there are four hoppers, each a quarter circle, and the material distribution rod is set to fit the right-angle side of each hopper, and the material distribution rod has a cross structure.

[0008] Furthermore, the top of the material distribution rod also has a triangular truncated platform, the length of which can cover the outlet at the bottom of the second funnel, and the width can extend into each hopper.

[0009] Furthermore, each of the aforementioned hoppers is a drawer-type internal component built into the cylinder and can be pulled out via a handle at the outer end of the hopper.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes vertical material distribution channels in each dispersion layer. After the material falls under its own weight, it is dispersed twice and collected by corresponding funnels. The dispersion layer can be designed as a group of steel rods or blades to maintain the density and verticality of the material distribution channels. Finally, the material is evenly sprinkled at the bottom outlet of the second funnel and divided by the material distribution rod at the bottom of the cylinder, distributing the powder into each hopper approximately equally. This method is more convenient and faster than traditional manual distribution and is highly practical. Attached Figure Description

[0013] The present invention will be further described below with reference to specific embodiments.

[0014] Example 1 like Figure 1 and Figure 2As shown in this embodiment, a simple automatic reduction device for powdered materials includes a cylinder 1. The cylinder 1 has a cavity inside and multiple hoppers 9 are provided at the bottom. The inner wall of the cylinder 1 is provided with a first dispersion layer 4, a first funnel 5, a second dispersion layer 6 and a second funnel 7 from top to bottom. The side wall of the cylinder 1 has a feed inlet 3 at a position higher than the first dispersion layer 4.

[0015] Both the first funnel 5 and the second funnel 7 have upward openings, respectively collecting the materials collected by the first dispersion layer 4 and the second dispersion layer 6. Multiple hoppers 9 are arranged in a circumferential array along the vertical axis of the cylinder 1, and can actually be configured as four. A cross-shaped material distribution rod 17 is then set at the intervals between the four circumferentially arrayed hoppers 9. The material distribution rod 17 is tightly fitted to the outer walls of the four hoppers 9, thus connecting the four hoppers 9 into a whole. The top surface height of the corresponding material distribution rod 17 is not lower than the top height of the hopper 9, and the length of the material distribution rod can cover the bottom outlet of the second funnel 7. After being continuously dispersed and collected twice, the powder finally leaks out from the bottom of the second funnel 7. Due to the length and height design of the material distribution rod 17, it can cover the powder leaking from the second funnel 7 and contact the powder before the hoppers 9. The cross structure also corresponds exactly to the four circumferentially arrayed hoppers 9, ultimately achieving the one-to-four division of the powder by the material distribution rod 17.

[0016] Regarding the powder dispersion process, in this embodiment, the first dispersion layer 4 is a multi-layer steel rod assembly, each layer of which includes multiple parallel steel rods, and the axial directions of the steel rods in adjacent layers intersect in a plane. Similarly, the second dispersion layer 6 has the same structure as the first dispersion layer 4.

[0017] Through multi-layered and parallel staggered steel rod groups, a nearly dense distribution channel can be formed between the steel rods. In practical applications, the first dispersion layer 4 and the second dispersion layer 6 can each be set as three-layer steel rod groups. Utilizing the non-stick properties of the steel rods themselves with the powder, the powder material enters through the feed inlet 3 and falls by its own weight. Then, it comes into contact with and collides with the three-layer steel rod group in the first dispersion layer 4. The fixed steel rods are placed crosswise to fully ensure the collision area and number of times the powder material is impacted. The powder material is then collected and gathered by the first funnel 5. After the powder material leaks out of the first funnel 5, it can be dispersed a second time by the steel rods in the second dispersion layer 6. Finally, it is collected and gathered by the second funnel 7. After the second collection, the material tends to be in a smooth and separated state. After falling out from the bottom of the second funnel 7, it can be separated by the distribution rod 17 to achieve reduction. The reduction process is achieved by the distribution rod 17 contacting the powder material.

[0018] As can be seen, in order to achieve rapid powder reduction, this utility model physically disperses the powder twice. Through the vertical dispersing channels in each dispersion layer, the powder is dispersed twice under its own gravity and collected by each corresponding funnel. Finally, it is evenly sprinkled at the bottom outlet of the second funnel 7 and reduced by the distributing rod 17 at the bottom of the cylinder 1, so that the powder is approximately equally divided into each hopper 9, which is convenient and fast.

[0019] Example 2 like Figure 2 and Figure 3 As shown, the difference from Embodiment 1 is that, based on the limited contact and collision of the steel rod with the powder material, in order to further improve the uniformity of the powder material, this embodiment sets the second dispersion layer 6 as a distribution plate 11 and a buffer platform 12. The top of the buffer platform 12 is formed with a conical buffer part 13, and the bottom is a columnar connecting part 14. The distribution plate 11 is fixedly sleeved on the side wall of the connecting part 14. The distribution plate 11 is composed of a plurality of partition leaves 15 that are equidistantly arranged around the connecting part 14 in the axial direction. The inner end of each partition leaf 15 near the connecting part 14 is plate-shaped, and the outer end is forked and open.

[0020] As can be seen, in this embodiment, the powder dispersed by the steel rod group in the first dispersion layer 4 can be buffered by the frustum-shaped buffer section 13. One end of the cone of the buffer section 17 faces upward to correspond to the bottom outlet of the first funnel 5. The powder that leaks out after being collected by the first funnel 5 can slide down along the cone end of the buffer section 17 and roll down the cone-shaped slope of the buffer section 17 into the second dispersion layer 6. The slope of the side wall of the corresponding buffer section becomes steeper from top to bottom, further improving the smoothness of the powder falling process.

[0021] Similarly, the size of the buffer section can be designed to correspond to the distribution plate 11. Specifically, the outer edge of the bottom end of the buffer section corresponds to the connection between the inner and outer ends of the separator leaf 15. The top of the connecting part 14 is exposed outside the distribution plate 11, and the exposed shaft section is circumferentially concave inward, with the concave depth corresponding to the inner end length of the separator leaf 15.

[0022] The powder falling from the first funnel 5 either falls vertically to the distribution plate 11 or rolls down along the side wall of the buffer section 13, and then falls into the bifurcated opening at the outer end of the separator leaf 15. Considering that the buffer section 13 itself occupies part of the area 6 of the second dispersion layer, the height of the connecting part 14 is designed to expose the distribution plate 11, and the exposed shaft section is recessed in the form of a ring to reduce the impact on the area occupied by the second dispersion layer 6. The depth of the recess corresponds exactly to the inner end length of the separator leaf 15. After the powder leaves the buffer section 13, some of the powder will fall freely onto the separator leaf 15 and be dispersed by the sheet-like structure of the separator leaf 15 itself.

[0023] Both the space between the partition blades 15 and the bifurcated openings at the outer ends of the partition blades 15 are vertical material distribution channels. With this structure, the powder is reduced in size. During the collection process in the second funnel 7, the powder can be regarded as being collected in a circumferential manner that approximately conforms to the slope of the inner wall of the second funnel 7 itself. The material is more thoroughly dispersed, which indirectly ensures the uniformity of the material distribution by the subsequent distribution rod 17.

[0024] Furthermore, in this embodiment, there are four hoppers 9, each a quarter circle in shape. The distributing rod is set to fit against the right-angled side of each hopper 9, and the distributing rod has a cross structure. The top of each distributing rod also has a triangular truncated platform 16 protruding from it. The length of the truncated platform 16 can cover the outlet at the bottom of the second funnel 7, and the width can extend into each hopper 9.

[0025] By using the corner platform 16 at the top of the distribution bar, the material can slide into its respective hopper 9 due to its slope, resulting in better uniformity.

[0026] Similarly, in the actual product, each of the aforementioned hoppers 9 can be built into the cylinder 1 as a drawer, and can be pulled out by the handle 10 at the outer end of the hopper 9 when retrieving materials, further improving practicality.

[0027] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
