Description

Technical Field

[0001] This application relates to the technical field of ball mills, and particularly to a ball milling device for the production of copper-based catalysts. Background Art

[0002] A ball mill is a device that loads a certain number of steel balls into a cylinder as grinding media to crush the materials therein. When the cylinder of the ball mill rotates, the grinding media, due to inertia and centrifugal force, adheres to the inner wall of the cylinder and is carried away. When it is carried to a certain height, it falls under the action of gravity, causing the falling grinding media to break the materials in the cylinder, thereby completing the crushing operation of the materials.

[0003] However, when the grinding media and materials in the existing ball mill are carried to a high place and projected, due to the large difference in weight between the grinding media and the materials, the inertia and centrifugal force they receive are quite different, resulting in the misalignment of their landing points, and further leading to a low effective impact degree of the grinding media on the materials. At the same time, the materials at the bottom layer of the cylinder will continuously penetrate into the gaps between the grinding media with the movement of the grinding media above, resulting in less materials on the surface of the bottom-layer grinding media, further reducing the effective impact of the falling grinding media on the materials, and thus greatly reducing the grinding effect and efficiency of the ball mill on the materials.

[0004] Therefore, there is an urgent need for a ball milling device to solve the defects existing in the actual use of the existing ball mill. Summary of the Invention

[0005] This application proposes a ball milling device for the production of copper-based catalysts, which has the advantages of being able to adjust the landing point of the materials when they are thrown, making the coincidence degree with the landing point of the grinding media relatively high, improving the effective impact of the grinding media on the materials, and having a good grinding effect and high efficiency on the materials. It is used to solve the problem that when the grinding media and materials in the existing ball mill are carried to a high place and projected in the cylinder, due to the large difference in weight between the grinding media and the materials, the landing points between them are misaligned, resulting in a low effective impact degree of the grinding media on the materials. At the same time, the materials at the bottom layer of the cylinder will continuously penetrate into the gaps between the grinding media with the movement of the grinding media above, resulting in less materials on the surface of the bottom-layer grinding media, further reducing the effective impact of the falling grinding media on the materials, and thus greatly reducing the grinding effect and efficiency of the ball mill on the materials.

[0006] To achieve the above object, the present application adopts the following technical solution: A ball milling device for producing a copper-based catalyst, comprising an outer cylinder body. On one side of the outer surface of the outer cylinder body, a transmission gear is fixedly installed and is in transmission connection with an external driving device through the transmission gear, so as to drive the outer cylinder body to rotate accordingly. On the inner wall of the outer cylinder body, there is a spiral conveyor belt for conveying the crushed materials. An inner cylinder body containing a certain number of grinding media is movably sleeved inside the outer cylinder body, and several groups of filter holes are provided inside the inner cylinder body, so that the crushed materials can be filtered out through the filter holes and discharged through the spiral conveyor belt on the outer cylinder body, enabling the grinding media dropped on the inner cylinder body to contact the unground materials. At the same time, a hollow-structured right end shaft is movably sleeved at one end of the inner cylinder body, and the inside of the right end shaft is communicated with the material conveying system, so that the material to be crushed can be conveyed into the inner cavity of the inner cylinder body through the right end shaft. A left end shaft is movably sleeved at the other end of the inner cylinder body, and a planetary gear set is provided on the outer surface of the left end shaft. Under the action of the planetary gear set, when the outer cylinder body rotates, the inner cylinder body rotates in the opposite direction, and under the action of the right end shaft and the left end shaft, the outer cylinder body and its structures can be fixedly installed on the bracket.

[0007] Further, at the top of the right side of the inner wall of the inner cylinder body, there is a lifting plate. The two ends of the lifting plate are respectively fixedly installed with connecting rods through a group of elastic members. The two groups of connecting rods are respectively fixedly connected to the inside of the right end shaft and the left end shaft. Therefore, for the setting of the lifting plate, a deflector structure can be formed inside the inner cylinder body to adjust the landing position of the materials when they are dropped, so that it can coincide with the landing position of the grinding media, improving the effective impact of the grinding media on the materials on this ball milling device, and making the grinding effect and efficiency of the materials better.

[0008] Further, the top of the outside of the lifting plate is set as an inwardly concave curved surface structure. Among them, for the setting of the inwardly concave curved surface structure on it, it is used to control the landing position of the materials. And due to the setting of the inwardly concave curved surface structure, a scraper structure is formed at the top of the lifting plate, which can effectively prevent the materials from adhering to the inner wall of the inner cylinder body and causing blockage of the filter holes on it.

[0009] Further, a convex plate with an arc-shaped inner wall is fixedly installed at the bottom of the inner wall of the inner cylinder body, and through holes corresponding to the filter holes are provided on the convex plate. When the convex plate contacts the outer surface of the lifting plate with the rotation of the inner cylinder body, under the extrusion of the convex plate, the lifting plate can be forced to displace inward to a certain extent and stretch the elastic members, which can effectively increase the landing range of the materials and make it coincide with the landing position of the grinding media. At the same time, due to the lifting plate displacing and vibrating to a certain extent, the materials can be effectively prevented from adhering to the inwardly concave curved surface of the lifting plate.

[0010] Further, according to the position of the lifting plate, the rotation direction of the inner cylinder is set to clockwise rotation, so as to ensure that the grinding media can be projected under the action of inertia and centrifugal force.

[0011] Further, the movement trajectory of the grinding media projected when the inner cylinder rotates clockwise does not intersect with the lifting plate, so as to ensure that the projected grinding media does not interfere with the lifting plate, thereby effectively improving the stability and reliability of the ball mill equipment during operation.

[0012] Further, a discharge ring groove communicating with the inner wall is provided on the right side of the outer surface of the outer cylinder. When the crushed material is pushed to the right side of the inner cavity of the outer cylinder under the action of the spiral conveyor belt, the crushed material can be discharged through the discharge ring groove.

[0013] The beneficial effects of the present invention are as follows:

[0014] For the ball mill equipment for producing copper-based catalysts provided in this application, the setting of the lifting plate can form a deflector structure inside the inner cylinder to adjust the landing position of the material when it is dropped, so that it can coincide with the landing position of the grinding media, improving the effective impact of the grinding media on the material on the ball mill equipment, making the grinding effect on the material better and the efficiency higher, and under the extrusion of the convex plate, the lifting plate can be forced to displace inward to a certain extent and stretch the elastic member, further increasing the landing range of the material and the probability of the landing positions of the grinding media coinciding.

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] As Figure 1 , Figure 3 shown, a ball milling device for the production of copper-based catalysts includes an outer cylinder body 1. One side of the outer surface of the outer cylinder body 1 is fixedly installed with a transmission gear 2, and is in transmission connection with an external driving device through the transmission gear 2, so as to drive the outer cylinder body 1 to rotate accordingly. A spiral conveyor belt 3 for conveying crushed materials is provided on the inner wall of the outer cylinder body 1. An inner cylinder body 4 containing a certain number of grinding media is movably sleeved inside the outer cylinder body 1, and a number of groups of filter holes 5 are provided inside the inner cylinder body 4. Thus, the crushed materials can be filtered out through the filter holes 5 and discharged through the spiral conveyor belt 3 on the outer cylinder body 1, so that the grinding media dropped on the inner cylinder body 4 can contact the unground materials. At the same time, a hollow-structured right end shaft 6 is movably sleeved at one end of the inner cylinder body 4, and the inside of the right end shaft 6 is communicated with the material conveying system. Thus, the materials to be crushed can be conveyed into the inner cavity of the inner cylinder body 4 through the right end shaft 6. A left end shaft 7 is movably sleeved at the other end of the inner cylinder body 4, and a planetary gear set 8 is provided on the outer surface of the left end shaft 7. Under the action of the planetary gear set 8, when the outer cylinder body 1 rotates, the inner cylinder body 4 rotates in the opposite direction. Under the action of the right end shaft 6 and the left end shaft 7, the outer cylinder body 1 and its structures can be fixedly installed on the bracket;

[0024] At the same time, under the action of the material conveying system on the right end shaft 6 and the filter holes 5 on the inner cylinder body 4, the ball milling device can form a continuous working state. During the process of discharging the crushed materials by using the filter holes 5 and the spiral conveyor belt 3, the materials to be crushed can be fed into the inner cavity of the inner cylinder body 4 by using the hollow structure of the right end shaft 6.

[0025] As Figure 2 , Figure 4As shown, in this technical solution, a lifting plate 9 is provided at the top on the right side of the inner wall of the inner cylinder 4. Both ends of the lifting plate 9 are fixedly installed with connecting rods 10 through a set of elastic members 11 respectively. The two groups of connecting rods 10 are fixedly connected to the inside of the right end shaft 6 and the left end shaft 7 respectively. Therefore, the setting of the lifting plate 9 can form a deflector structure inside the inner cylinder 4 to adjust the landing position of the material when it is thrown, so that it can coincide with the landing position of the grinding medium, improving the effective impact of the grinding medium on the material on this ball mill equipment, and making the grinding effect on the material better and the efficiency higher.

[0026] As Figure 4 、 Figure 5 shown, in this technical solution, the top of the outside of the lifting plate 9 is set as an inwardly concave curved surface structure. Among them, the setting of the inwardly concave curved surface structure is used to control the landing position of the material. And due to the setting of the inwardly concave curved surface structure, a scraper structure is formed at the top of the lifting plate 9. Therefore, it can effectively prevent the material from adhering to the inner wall of the inner cylinder 4 and causing blockage of the filter holes 5 on it.

[0027] As Figure 4 、 Figure 5 shown, in this technical solution, a convex plate 12 with an arc-shaped inner wall is fixedly installed at the bottom of the inner wall of the inner cylinder 4, and through holes corresponding to the filter holes 5 are provided on the convex plate 12. Therefore, when the convex plate 12 contacts the outer surface of the lifting plate 9 as the inner cylinder 4 rotates, under the extrusion of the convex plate 12, the lifting plate 9 can be forced to displace inward to a certain extent and stretch the elastic member 11. Therefore, it can effectively increase the landing range of the material and make it coincide with the landing position of the grinding medium. At the same time, due to the lifting plate 9 displacing and vibrating to a certain extent, it can effectively prevent the material from adhering to the inwardly concave curved surface of the lifting plate 9.

[0028] As Figure 4 shown, in this technical solution, according to the position of the lifting plate 9, the rotation direction of the inner cylinder 4 is set to rotate clockwise, so as to ensure that the grinding medium can be projected under the action of inertia and centrifugal force.

[0029] In this technical solution, there will be no intersection between the movement trajectory of the grinding medium projected when the inner cylinder 4 rotates clockwise and the lifting plate 9. Therefore, it is ensured that the projected grinding medium will not interfere with the lifting plate 9, so as to effectively improve the stability and reliability of this ball mill equipment during operation.

[0030] In this technical solution, a discharge ring groove communicating with its inner wall is opened on the right side of the outer surface of the outer cylinder 1. Therefore, when the crushed material is pushed to the right side of the inner cavity of the outer cylinder 1 under the action of the spiral conveyor belt 3, the crushed material can be discharged through the discharge ring groove.

[0031] The foregoing description of the disclosed embodiments enables those skilled in the art to practice or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
