Abstract
Description
Technical Field
[0001] This utility model relates to a material distribution device, and more particularly to a powder distribution device. Background Technology
[0002] In the production of graphite electrodes, calcined petroleum coke needs to be ground into powder for use. The content of powder with a particle size below 75μm is usually controlled and needs to be kept stable to ensure stable product quality. However, during the process of transporting the powder to the silo, due to the natural accumulation of the powder layer, the particle size distribution of the powder in the silo becomes uneven. In order to solve this problem, this material distribution device was developed. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the problems of the prior art and provide a powder distribution device that can uniformly distribute powder in the feeding bin.
[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution:
[0005] A powder distribution device includes a hopper, wherein the inlet and outlet of the hopper are respectively located at the center of the top and bottom of the hopper to facilitate the entry and exit of powder.
[0006] The upper part of the hopper is equipped with a feeding platform that is narrower at the top and wider at the bottom. The center point of the feeding platform is located directly below the feed inlet of the hopper. Straight feeding plates are evenly distributed around the circumference of the feeding platform. A feeding groove is formed between every two feeding plates. The length of the feeding groove varies. The top of each feeding groove is on the same plane as the top of the feeding platform. The bottom of the shortest feeding groove is close to the top of the feeding platform, and the bottom of the longest feeding groove is on the same plane as the bottom of the feeding platform. The dimensions of the feeding platform match the dimensions of its corresponding feeding groove. In this way, dropping points are set out from the center point of the hopper around the circumference, which facilitates the even dropping of powder into the hopper.
[0007] Furthermore, the fabric troughs are divided into four groups, which are evenly distributed around the fabric platform. Each group of fabric troughs includes six troughs in total: three long, two medium, and one short. The tops of the six fabric troughs are on the same plane as the top of the fabric platform, the bottoms of the three long fabric troughs are on the same plane as the bottom of the fabric platform, the bottom of the one short fabric trough is close to the top of the fabric platform but does not overlap with the top of the fabric platform, and the bottoms of the two medium fabric troughs are located between the bottoms of the long and short fabric troughs.
[0008] Furthermore, the fabric troughs are divided into four groups, which are evenly distributed circumferentially on the fabric platform. Each group of fabric troughs includes six progressively shorter fabric troughs. The tops of the six fabric troughs are all on the same plane as the top of the fabric platform. The bottom of the longest fabric trough is on the same plane as the bottom of the fabric platform. The bottom of the shortest fabric trough is close to the top of the fabric platform but does not coincide with the top of the fabric platform. The bottoms of the other fabric troughs increase progressively from top to bottom.
[0009] Each material trough has a drop point at its bottom, which creates a circular pattern within the hopper, with drop points extending from the center circumference to the side circumference, preventing material from accumulating due to insufficient drop points.
[0010] Furthermore, the fabric platform is mounted on a crossbeam inside the hopper, and the end of the crossbeam is fixedly connected to the inner wall of the hopper.
[0011] The beneficial effects of this utility model are as follows:
[0012] This invention utilizes the varying lengths of the feeding troughs on the feeding platform to evenly distribute the powder within the hopper, thus solving the problem of uneven powder distribution caused by natural accumulation due to insufficient feeding points when the powder enters the hopper.

[0023] The names of the messages or information exchanged between the multiple devices in this embodiment of the invention are for illustrative purposes only and are not intended to limit the scope of these messages or information.
[0024] Example 1: As Figure 1-3 As shown,
[0025] A powder distribution device, such as Figure 1 It includes a hopper 1, with the inlet 2 and outlet 2 on the hopper 1 respectively located at the center of the top and bottom of the hopper 1, to facilitate the entry and exit of powder.
[0026] The upper part of the hopper 1 is equipped with a material distribution platform 3 that is narrow at the top and wide at the bottom. The material distribution platform 3 is set on the cross beam 4 inside the hopper 1. The central intersection point of the cross beam 4 can rotate relative to each other. The end of the cross beam 4 is fixedly connected to the inner wall of the hopper 1 using L-shaped pads and screws.
[0027] The center point of the material distribution table 3 is located directly below the feed inlet 2 of the hopper 1. Straight material distribution plates 5 are evenly distributed around the circumference of the material distribution table 3. A material distribution groove 6 is formed between every two material distribution plates 5. The lengths of the material distribution grooves 6 are different. The dimensions of the material distribution table 3 match the dimensions of its corresponding material distribution grooves 6.
[0028] The fabric troughs 6 are divided into four groups. The four groups of fabric troughs 6 are evenly distributed in a circle on the fabric platform 3. Each group of fabric troughs 6 includes three long, two medium and one short fabric troughs in total.
[0029] The tops of all six fabric troughs 6 coincide with the top of the fabric platform 3. The bottoms of the three longer fabric troughs 6 coincide with the bottom of the fabric platform 3. The bottom of the one shorter fabric trough 6 is located at one-third of the height of the fabric platform 3, and the bottoms of the two medium-sized fabric troughs 6 are located at two-thirds of the height of the fabric platform 3. Figure 2 and Figure 3 As shown.
[0030] This creates a circular pattern within the hopper 1, with twelve material drop points evenly distributed from the center circumference to the side circumference, ensuring that the powder falls evenly into the hopper 1 and preventing material accumulation due to insufficient drop points.
[0031] When in use, the material distribution platform 3 is fixed on the crossbeam 4. After the powder enters the hopper 1 through the feed port 2 on the hopper 1, it falls to the center of the material distribution platform 3 and then flows along the material distribution trough 6 to various positions in the hopper 1, which solves the problem of uneven particle size distribution caused by the natural accumulation of material in the center of the hopper 1.
[0032] Example 2: Figure 1 , Figure 4 and Figure 5 As shown: The difference from the embodiment is that each set of fabric troughs 6 includes six fabric troughs 6 that are successively shortened.
[0033] The tops of all six fabric troughs 6 coincide with the top of the fabric platform 3. The bottom of the longest fabric trough 6 coincides with the bottom of the fabric platform 3. The bottoms of the remaining five fabric troughs 6 are located at five-sixths, four-sixths, three-sixths, two-sixths, and one-sixth of the height of the fabric platform 3, respectively, from bottom to top.
[0034] This creates a circular pattern within hopper 1, with twenty-four material drop points evenly distributed from the center circumference to the side circumferences. With more drop points, the material is more evenly distributed.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments.
