Description

Technical Field

[0001] The utility model relates to the technical field of bauxite processing, in particular to a bauxite grinding device. Background Art

[0002] Bauxite, also known as bauxite or bauxite, is a mineral containing aluminum oxide. Its main component is aluminum oxide. It is usually white or off-white, and is brownish yellow or light red due to the iron content. The density of bauxite is about 3.4g / cm 3 , hardness is between 1 and 3, it is opaque, brittle, and extremely difficult to melt. It is insoluble in water, but soluble in sulfuric acid and sodium hydroxide solution. The main use of bauxite is to refine metallic aluminum. It is also used to manufacture refractory materials, abrasive materials, etc. In the metallurgical industry, bauxite is used as a flux, thermal insulation material and fireproof material to improve the quality and output of metallurgical products. In the building materials industry, bauxite is used to manufacture refractory bricks, high-performance concrete, etc. In addition, bauxite is also widely used in the ceramic industry to improve the structure and properties of ceramics.

[0003] After searching, the patent number "CN217747320U" mentioned in the text that "the utility model discloses a grinding device for a bauxite fine powder production line, including a box body, a discharge hopper connected to the upper end surface of the box body, a feed hopper connected to the upper side of the box body, the feed hopper extending into the box body, a first transmission mechanism provided below the feed hopper, a second transmission mechanism provided on both sides of the box body, a grinding mechanism installed inside the box body, the first transmission mechanism and the second transmission mechanism both being connected to the grinding mechanism". When in use, the first bevel gear and the second bevel gear in the first transmission mechanism are engaged, and the power of the first motor is transmitted to the grinding disc, causing the grinding disc to rotate. Under the action of centrifugal force, the grinding disc rotates. The bauxite material entering through the feed hopper moves toward the periphery of the grinding disc and enters the area of ​​the grinding roller. Then the second transmission mechanism rotates the grinding roller to grind the bauxite material in the area. Through the engagement of the grinding disc and the grinding roller, the bauxite material can be fully ground into bauxite fine powder, which greatly improves the production efficiency of bauxite fine powder. However, in the bauxite processing process, after the bauxite is excavated, it needs to be crushed to prepare for the subsequent fine processing. However, before the bauxite is ground into powder, since the bauxite is in stone form, if it is not crushed, it is easy to be difficult to grind into powder in the subsequent grinding process.

[0004] To this end, we provide a bauxite grinding device to solve the above problems. Utility Model Content

[0005] The present application provides a grinding device for bauxite, which solves the problem that during the bauxite processing process, after the bauxite is excavated, the bauxite needs to be crushed to prepare for subsequent fine processing. However, before the bauxite is ground, since the bauxite is in a stone-like state, if it is not crushed, it is easy to be difficult to grind in the subsequent grinding process.

[0006] The present application provides a bauxite grinding device, comprising a top box and a bauxite grinding mechanism, wherein the bauxite grinding mechanism is provided inside the top box;

[0007] The bauxite grinding mechanism includes a soil crushing assembly arranged inside the top box, a soil rolling assembly is installed on the lower side of the soil crushing assembly, and support and shock-absorbing assemblies are installed on the left and right sides of the soil rolling assembly.

[0008] Preferably, the soil crushing assembly includes a soil bundle box fixed on the upper side of the top box, toothed rollers are installed on the inner side of the top box, and a roller power motor is installed on the left side of the top box.

[0009] Preferably, the soil rolling assembly includes a soil rolling box fixed to the lower side of the top box, heat dryers are installed on all four sides of the inner side of the soil rolling box, soil rolling columns are installed at the lower end of the inner side of the soil rolling box, and soil rolling motors are installed on the left side of the soil rolling columns.

[0010] Preferably, the soil-milling columns and the soil-milling box are symmetrically arranged about the central axis, and the interval between the soil-milling columns is 0.3 cm.

[0011] Preferably, the support and shock-absorbing assembly includes connecting pieces fixed on the left and right sides of the soil rolling box, support columns are installed on the lower sides of the connecting pieces, and large-plate shock-absorbing pads are installed on the ends of the support columns.

[0012] Preferably, a bauxite filter assembly is installed on the lower side of the soil grinding assembly, and the bauxite filter assembly includes a filter support frame fixed on the lower side of the connecting piece, a vibration groove is provided in the middle of the filter support frame, a filter screen plate is installed on the inner side of the vibration groove, a vibration motor is installed on the lower side of the filter screen plate, and a rotating shaft is installed on the left and right ends of the rear side of the filter screen plate.

[0013] Preferably, the vibration motor and the filter screen are welded, and the vibration motor and the filter screen are equidistantly distributed in three groups.

[0014] When in use, first fix the top box to the position where it needs to be used through the supporting column and the large plate shock-absorbing pad, and then pour bauxite into the soil box. At this time, the roller power motor drives the toothed roller to crush the bauxite blocks, and the crushed bauxite falls into the soil grinding box. Then the hot dryer heats the bauxite blocks to dry them. During the drying process, the soil grinding motor in the soil grinding box drives the soil grinding column to grind the bauxite, and the ground bauxite will fall into the filter screen in the filter support frame. At the same time, the vibration motor in the vibration trough vibrates the filter screen at the same frequency for screening. The soil that misses the mesh will fall into the next level, and the bauxite at this level will be discharged along the direction of the rotating axis, so as to achieve the effect of grinding and grading.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. Through the setting of the bauxite grinding mechanism, when it is needed, the roller power motor in the soil box drives the toothed roller to cut the bauxite into small particles. In this way, in the subsequent crushing process, due to the smaller diameter of the bauxite, it is more convenient to grind, and the density after grinding is finer. The hot dryer will heat the bauxite accumulated in the soil grinding box to make the bauxite drier, which is convenient for the subsequent grinding process. The small pieces of bauxite are squeezed through the gap between the two soil grinding columns to achieve the grinding effect. And because the bauxite itself is brittle, it can achieve the grinding effect. The support column supports the whole body, and the large plate shock-absorbing pad provides a larger force area, so that the overall operation is more stable, avoiding position displacement or even rollover during operation.

[0017] 2. Through the setting of the bauxite filter assembly, when it is needed, the filter plate in the vibration tank can filter the bauxite through multiple layers of filtration to different degrees of fineness, and because the filter plate is tilted at a certain angle, the bauxite will flow out along the tilt angle. The vibration motor will drive the filter plate to vibrate up and down during the filtration process, so that the bauxite can be filtered faster and the screening process can be more complete.

[0018] In summary, the present application can achieve a better grinding effect by subjecting the bauxite to multi-stage filtration and multi-stage processing, and the size of the ground bauxite can be distinguished. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to enable people skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0026] See also Figure 1-4 A bauxite grinding device comprises a top box 1 and a bauxite grinding mechanism 2, wherein the bauxite grinding mechanism 2 is provided inside the top box 1;

[0027] The bauxite grinding mechanism 2 includes a soil crushing assembly 21 arranged inside the top box 1, a soil grinding assembly 22 is installed on the lower side of the soil crushing assembly 21, and support and shock absorbing assemblies 23 are installed on the left and right sides of the soil grinding assembly 22.

[0028] In the present invention, the soil crushing assembly 21 includes a soil box 211 fixed on the upper side of the top box 1, and toothed rollers 212 are installed on the inner side of the top box 1. A roller power motor 213 is installed on the left side of the top box 1. When needed, the roller power motor 213 in the soil box 211 drives the toothed rollers 212 to chop the bauxite into small particles. In this way, in the subsequent crushing process, due to the smaller diameter of the bauxite, it is more convenient to grind the powder, and the fineness after grinding is finer.

[0029] In the present invention, the soil grinding assembly 22 includes a soil grinding box 221 fixed to the lower side of the top box 1, and heat dryers 222 are installed on all four sides of the inner side of the soil grinding box 221. The lower end of the inner side of the soil grinding box 221 is installed with soil grinding columns 223, and the left side of the soil grinding columns 223 is installed with soil grinding motors 224. When needed, the heat dryer 222 will heat the bauxite accumulated in the soil grinding box 221, so as to make the bauxite drier and facilitate the subsequent grinding process.

[0030] In the present invention, the soil-grinding columns 223 and the soil-grinding box 221 are symmetrically arranged along the central axis, and the interval between the soil-grinding columns 223 is 0.3 cm. When needed, the two soil-grinding columns 223 can squeeze the small pieces of bauxite through the gap between them, thereby achieving the effect of grinding. Moreover, since bauxite itself is relatively brittle, it can achieve the grinding effect.

[0031] In the present invention, the support and shock-absorbing assembly 23 includes connecting parts 231 fixed on the left and right sides of the soil-rolling box 221. Support columns 232 are installed on the lower sides of the connecting parts 231, and large-plate shock-absorbing pads 233 are installed at the ends of the support columns 232. When it is needed, the support columns 232 will support the whole, and the large-plate shock-absorbing pads 233 will provide a larger force-bearing area, so that the overall operation is more stable and avoids position displacement or even rollover during operation.

[0032] In some embodiments, a bauxite filter assembly 3 is installed on the lower side of the soil grinding assembly 22. The bauxite filter assembly 3 includes a filter support frame 31 fixed on the lower side of the connecting member 231. A vibration groove 32 is provided in the middle of the filter support frame 31. A filter screen plate 33 is installed on the inner side of the vibration groove 32. A vibration motor 34 is installed on the lower side of the filter screen plate 33. A rotating shaft 35 is installed on the left and right ends of the rear side of the filter screen plate 33. When needed, the filter screen plate 33 in the vibration groove 32 can filter the bauxite through different degrees of fineness through multi-layer filtration, and since the filter screen plate 33 is tilted at a certain angle, the bauxite will flow out along the tilt angle.

[0033] In some embodiments, the vibration motor 34 and the filter screen plate 33 are welded, and the vibration motor 34 and the filter screen plate 33 are distributed at equal distances, and the distribution number is three. When needed, the vibration motor 34 will drive the filter screen plate 33 to vibrate back and forth in the up and down direction during the filtering process of the filter screen plate 33, thereby making the bauxite faster and the screening process more complete.

[0034] It can be seen from the above technical solution that when in use, first, the connecting piece 231 is fixed to the position where it needs to be used through the support column 232 and the large plate shock-absorbing pad 233, and then bauxite is poured into the bundle soil box 211. At this time, the roller power motor 213 drives the toothed roller 212 to crush the bauxite block, and the crushed bauxite falls into the soil grinding box 221, and then the hot dryer 222 heats and dries the bauxite block. During the drying process, the soil grinding motor 224 in the soil grinding box 221 drives the soil grinding column 223 to grind the bauxite, and the ground bauxite will fall into the filter screen 33 in the filter support frame 31. At the same time, the vibration motor 34 in the vibration groove 32 vibrates the filter screen 33 at the same frequency for screening. The soil that misses the gauze will fall into the next level, and the bauxite at this level will be discharged along the direction of the rotating shaft 35, so as to achieve the effect of grinding and grading. In this way, the use process of a bauxite grinding device is completed.
