Description

Technical Field

[0001] The utility model relates to the technical field of ball mills, and specifically relates to an installation structure of a partition plate of a ball mill. Background Art

[0002] When the ball mill works, materials enter the first bin of the mill evenly through the feeding hollow shaft spiral of the feeding device. There are stepped liners or corrugated liners in this bin, and various specifications of steel balls are installed inside. When the cylinder rotates, the centrifugal force brings the steel balls to a certain height and then they fall, hitting and grinding the materials. After the materials are roughly ground in the first bin, they enter the second bin through a single-layer partition plate. There are flat liners in this bin and steel balls inside, further grinding the materials. The powder is discharged through the discharge grate plate to complete the grinding operation.

[0003] The partition plate is vertically arranged inside the cylinder of the ball mill and is used to filter the materials in the first bin. The partition plate is assembled by multiple plates, and there are many connecting gaps. After working for a long time, it is very likely that the partition plate will shake or even be damaged due to the extrusion and friction of the materials and steel balls or the loosening of the connection. It can be seen that the installation stability of the partition plate directly affects its service life. However, the existing partition plates are directly fixed to the cylinder through screws or bolts, and the installation stability needs to be improved. Content of the Utility Model

The positions of the plurality of baffle plates 51 respectively correspond to the gap positions between two adjacent partition plates 61. The support plate 53 and the fixing plate 63 are fixed to the inner wall of the cylinder body 1 by screws 7 passing through and screwed into the threaded holes 8. The mounting plate 2, the partition plate 61 and the connecting plate 52 are fixed by bolts 4; the partition plate 6 further includes an insertion plate 62, the insertion plate 62 is designed to protrude outward along the radial direction of the partition plate 61, and a circle of insertion slots 3 are arranged at the positions of the inner side wall of the cylinder body 1 corresponding to the insertion plate 62, and the insertion plate 62 is inserted into the insertion slots 3; the support plate 53, the plurality of baffle plates 51 and the connecting plate 52 are integrally formed; the support protection plate 5 is made of cemented carbide material.

[0020] The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, which are as follows:

[0021] According to the attached Figures 1-5 specification, when the present invention is installed, the support plate 53 of the support protection plate 5 and the fixing plate 63 of the partition plate 6 both face the back, and the so-called back refers to the side where the material filtration flows. Figure 1In the figure, it refers to the left side of the partition plate 6. During installation, first, multiple partition plates 6 are arranged in a circular matrix and connected in sequence. Since the outer diameter of the support plate 53 is radially matched with the fixed plate 63 after arrangement, during installation, the support and protection plate 5 is installed into the groove formed by multiple partition plates 6, and the support plate 53 radially supports the fixed plate 63. It should be noted that after the support and protection plate 5 is installed, the gaps between the baffle plate 51 and the partition plate 61 need to be corresponding to achieve the purpose of axially supporting and protecting the gaps therebetween. Finally, the screw 7 passes through the support plate 53 and the fixed plate 63 and is screwed onto the threaded hole 8 of the cylinder body 1 for fixation to ensure the overall stability. Then, the mounting plate 2, the partition plate 61, and the connecting plate 52 are fixed by the bolt 4, and while assembling the mounting plate 2, the three are fixed at the same time. The number of the screws 7 and the number of the bolts 4 here are determined according to the number of the partition plates 6, generally one-to-one for fixation. The through holes of the corresponding components at the fixation positions of the screws 7 and the bolts 4 are made in advance. This is the prior art and is well understood by those skilled in the art. Compared with the prior art of directly fixing with the screw 7 or the bolt 4, the utility model radially supports the fixed plate 63 of the partition plate 6 through the support and protection plate 5 and axially supports the gaps between the partition plates 6, thereby ensuring more stability between the partition plates 6 and between the partition plate 6 and the cylinder body 1, reducing vibration and shaking, increasing the service life of the partition plate 6, and having simple installation and obvious effects.

During installation, the insertion plate 62 is inserted into the slots 3 to limit the axial direction of the partition plate 6 and further ensure the stability of the partition plate 6.

[0023] Among them, the support plate 53, multiple baffle plates 51, and the connecting plate 52 are integrally formed, increasing their own stability and thus strengthening the stability of limiting the partition plate 6.

[0024] Among them, the support and protection plate 5 is made of cemented carbide material to increase the strength of installation and support and protection.
