Description

Technical Field

[0001] This invention relates to the field of ore concentration and compression processing technology, specifically to an ore concentration and compression processing technology. Background Technology

[0002] Ore concentration refers to the process of separating useful minerals from useless minerals in ore through physical or chemical methods to increase the content of useful minerals. The main purpose of ore concentration is to increase the concentration of useful components in the ore and reduce transportation and processing costs. Through the concentration process, the recovery rate of useful components in the ore can be significantly improved, and production costs and environmental pollution can be reduced. The main methods of ore concentration are: ore pretreatment, slurry concentration, suspension filtration and wet ore drying. Ore pretreatment includes crushing, screening and washing. Washing is generally completed by a drum washing machine.

[0003] The cleaning effect of the drum washing machine determines whether subsequent processes can proceed smoothly. When ore particles are cleaned in the drum washing machine, due to the limited length of the drum washing machine, small and large particles in the ore particles are not completely screened and are discharged together, resulting in incomplete screening of ore particles. In addition, some ore particles are very easy to get stuck in the screening holes of the drum washing machine during the screening process, causing blockage and affecting the normal screening and cleaning of the drum washing machine, ultimately affecting the effect of the ore particles after cleaning. Summary of the Invention

The ore is washed with water using a ore washing device to remove the mud and impurities attached to the surface.

[0006] S2. Mineral processing: Utilizing the density differences of different minerals in the ore, the minerals are separated under gravity using gravity separation equipment to obtain the desired ore particles, which are then mixed with water to obtain a slurry.

[0008] S4. Filtration of suspension: The concentrated slurry is filtered through a plate and frame filter press, so that the liquid in the suspension passes through the filter cloth, while the solid particles are trapped on the filter cloth.

The ore is washed with water using a ore washing device to remove the mud and impurities attached to the surface.

[0033] S2. Mineral processing: Utilizing the density differences of different minerals in the ore, the minerals are separated under gravity using gravity separation equipment to obtain the desired ore particles, which are then mixed with water to obtain a slurry.

[0034] S3. Concentrated Slurry: The centrifuge uses high-speed rotation to generate centrifugal force, which accelerates the sedimentation of solid particles and concentrates the required slurry.

[0035] S4. Filtration of suspension: The concentrated slurry is filtered through a plate and frame filter press, so that the liquid in the suspension passes through the filter cloth, while the solid particles are trapped on the filter cloth. The filter cake formed by the wet ore is discharged from the plate and frame filter press for collection.

[0036] S5. Drying wet ore: A dryer is used to heat the wet ore with hot air to accelerate the evaporation of moisture, thereby obtaining a dry ore product.

[0037] See Figure 2 and Figure 3 Step S1 is completed using a ore washing device, which includes a frame unit 1 and an anti-clogging unit 2. The anti-clogging unit 2 is installed on the frame unit 1 to treat any blockages on the frame unit 1 and prevent blockages from occurring. The frame unit 1 includes a fixed base 11, with rollers 12 symmetrically rotatably connected to the upper left side of the fixed base 11. A positioning plate 13 is fixedly installed on the upper end of the fixed base 11 and to the right of the rollers 12. An outer layer 14 for final screening of ore particles is provided in the middle of the positioning plate 13. A collecting sleeve 15 is fixedly installed on the right side of the fixed base 11, with the lower end of the collecting sleeve 15 extending along its circumference. The outer layer 14 has drainage holes 16 evenly distributed. A middle layer 17 is provided inside the outer layer 14. An inner layer 18 is provided at the left end of the outer layer 14 and inside the middle layer 17. The anti-clogging unit 2 includes an impact member 21. The right end of the fixed base 11 is provided with an impact member 21 that uses water pressure to impact the ore particles inside the blocked holes on the outer layer 14.

[0038] First, the outer layer 14 is started by an external motor. Then, the ore material mixed with water is fed into the inner layer 18 through the guide plate 144. The ore material and water tumble and move to the right. At the same time, the flushing component 23 washes the ore material moving to the right, thereby accelerating the separation of useful minerals from the muddy soil and clay. The ore material moving to the far right in the inner layer 18 falls into the middle layer 17 and continues to tumble and move to the left. The ore material moving to the far left in the middle layer 17 falls into the outer layer 14 and continues to tumble and move to the right. Smaller mineral particles are carried by the outer layer. 14 enters the collecting sleeve 15, and the sewage also enters the collecting sleeve 15. Part of the sewage enters the impact member 21 from the collecting sleeve 15 for filtration, and part of the sewage is discharged along with the smaller mineral particles. The larger mineral particles move to the right and are discharged along with the outer layer 14. During the agitation process, a small amount of ore particles are blocked in the outer layer 14, affecting the smooth discharge of the smaller mineral particles. During this period, the ore particles blocked in the holes on the outer layer 14 can be squeezed by the mechanical force of the vibrating member 22, and at the same time, the ore particles inside the blocked holes on the outer layer 14 can be impacted by the water pressure of the flushing member 23.

[0039] See Figure 2 and Figure 3 The outer layer component 14 includes an outer roller 141. The outer roller 141 is rotatably connected to the middle of the positioning plate 13. A mating wheel 142 is fixedly installed on the outer left side of the outer roller 141. The mating wheel 142 cooperates with the roller 12. A guide cylinder 143 is fixedly installed on the inner left side of the outer roller 141.

[0042] See Figure 3 and Figure 4 The vibrating element 22 includes a cylindrical spring 221. The upper end of the collecting sleeve 15 is provided with an installation groove. Cylindrical springs 221 are symmetrically fixedly installed on the upper end of the collecting sleeve 15 and on both sides of the installation groove. An arc-shaped vibrating plate 222 is fixedly installed on the lower end of the cylindrical springs 221. Top hole rods 223 are evenly fixedly installed on the lower end of the vibrating plate 222 along its circumference. A vibrating motor 224 is fixedly installed on the upper end of the vibrating plate 222 through a motor base.

[0043] See Figure 2 The right end of the collecting sleeve 15 is fixedly installed with a discharge plate 151. Drainage holes 152 are evenly opened along the linear direction of the discharge plate 151. The discharge plate 151 is fixedly connected to the support plate 211.

[0044] See Figure 2 , Figure 3 and Figure 5 The middle layer component 17 includes a first fixing rod 171. The first fixing rod 171 is symmetrically fixedly installed at the inner right end of the outer roller 141. The second fixing rod 172 is symmetrically fixedly installed at the inner end of the outer roller 141 and at the left side of the first fixing rod 171.

The second screen hole 174 is evenly opened along its circumference on the middle roller 173.

[0045] See Figure 4 and Figure 5 The inner layer component 18 includes an inner layer roller 181. The inner layer roller 181 is fixedly installed at the left end of the outer layer roller 141 and inside the middle layer roller 173. The inner layer roller 181 has sieve holes 182 evenly opened along its circumference. The inner end of the inner layer roller 181 has an arc-shaped guide plate 183 evenly fixedly installed along its circumference. The right end of the guide cylinder 143 is fixedly connected to the left end of the inner layer roller 181.

[0046] See Figure 5 The flushing component 23 includes a water supply pipe 231. The water supply pipe 231 is fixedly installed on the right end of the collecting sleeve 15 through a fixed bracket. The water supply pipe 231 is rotatably connected to the right side of the middle roller 173. A second water spray head 232 is evenly fixedly installed on the lower end of the water supply pipe 231. An inclined discharge plate 233 is fixedly installed on the right end of the collecting sleeve 15.

[0047] The working principle of this invention is as follows: First, the spur gear 146 is started by an external motor to rotate, thereby driving the outer drum 141, the middle drum and the inner drum to rotate. Then, the ore material mixed with water is fed into the inner drum 181 through the guide plate 144. The rotating inner drum 181 drives the ore material and water to tumble and stir together, moving to the right. At the same time, water is introduced into the water supply pipe 231 on the right side through the external water pipe, and sprayed out through the second water spray head 232 to wash the ore material moving to the right side, thereby accelerating the separation of useful minerals from muddy soil and clay.

[0048] Step 2: The ore material moving to the rightmost side in the inner drum 181 falls into the middle drum 173 and continues to tumble and agitate, moving to the left. The ore material moving to the leftmost side in the middle drum 173 falls into the outer drum 141 and continues to tumble and agitate, moving to the right. Smaller mineral particles enter the collecting sleeve 15 through the screen hole 1411 of the outer drum 141. Wastewater also enters the collecting sleeve 15. Part of the wastewater enters the water storage tank 212 from the collecting sleeve 15 for filtration, and part of the wastewater, along with the smaller mineral particles, is discharged from the discharge plate 151. The wastewater drips down through the drain hole 152. Larger mineral particles move to the right with the outer drum 141 and are discharged through the discharge plate 233.

[0049] Step 3: During the agitation process, some smaller mineral particles fall into the middle drum through the screen hole 182 of the inner drum, and then fall into the outer drum 141 through the screen hole 174 of the middle drum. Finally, they enter the collecting sleeve 15 through the screen hole 1411 of the outer drum 141 and are first discharged from the discharge plate 151. During the agitation process, a small amount of ore particles are blocked in the screen hole 1411 of the outer drum 141, affecting the smooth discharge of smaller mineral particles. During this period, the vibrating plate 222 is driven to vibrate up and down by the vibrating motor 224. The top hole rod 223 on the vibrating plate 222 squeezes the ore particles blocked in the screen hole 1411, causing them to re-enter the outer drum 141 for screening. At the same time, the filtered water in the water storage tank 212 is transported to the storage tank through the water pump 215 and the water guide pipe 214. The water is contained in the water box 216 and sprayed out through the spray head 217, impacting the screen holes 1411 of the outer roller 141. This squeezes the ore particles that are blocked in the screen holes 1411. With the combined pressure of the water and the squeezing force of the top hole rod 223, the ore particles blocked in the screen holes 1411 of the outer roller 141 are squeezed back into the outer roller 141, thus avoiding affecting the screening effect of the screen holes 1411 of the outer roller 141. The size of the screen holes 1411 of the outer roller 141 is smaller than the screen holes 174 of the middle roller 173, and the screen holes 174 of the middle roller 173 are smaller than the screen holes 182 of the inner roller 181. Since the larger the screen hole size, the less likely the screen hole will be blocked, the blockage of the screen holes 174 of the middle roller 173 and the screen holes 182 of the inner roller 181 can be ignored.
