Description

Technical Field

[0001] The invention relates to the technical field of ore concentration and compression processing, in particular to an ore concentration and compression processing technology. Background Art

[0002] Ore concentration refers to the separation of useful minerals from useless minerals in ore by 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 ore and reduce transportation and processing costs. Through the concentration process, the recovery rate of useful components in ore can be significantly improved, and production costs and environmental pollution can be reduced. The main methods of ore concentration are: ore pretreatment, concentrated slurry, filtered suspension and dried wet ore. Ore pretreatment includes crushing, screening and washing. Washing is generally completed by a drum ore washer.

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

An inclined discharge plate 233 is fixedly installed at the right end of the collecting sleeve 15.

[0045] Working principle of the present invention: Step 1: First, the spur gear 146 is started to rotate by an external motor, thereby driving the outer drum 141, the middle drum and the inner drum to rotate, and then the ore material mixed with water is sent into the inner drum 181 through the guide plate 144. The rotating inner drum 181 drives the ore material to roll and stir with the water and move to the right. At the same time, water is introduced into the water pipe 231 on the right through the external water pipe, and sprayed out through the second water spray head 232 to wash the ore material moving to the right, thereby accelerating the separation of useful minerals from muddy soil and clay.

[0046] Step 2: The ore material moves to the rightmost side in the inner drum 181 and falls into the middle drum 173 to continue tumbling and stirring, and moves to the left. The ore material moves to the leftmost side in the middle drum 173 and falls into the outer drum 141 to continue tumbling and stirring, and moves to the right. Mineral particles with smaller particles enter the aggregate sleeve 15 along with the sieve hole 1411 of the outer drum 141, and the sewage also enters the aggregate sleeve 15. Part of the sewage enters the water storage tank 212 from the aggregate sleeve 15 for filtration, and part of the sewage is discharged from the discharge plate 151 along with the mineral particles with smaller particles. The sewage drips downward along the drainage hole 2 152, and the mineral particles with larger particles move to the right along with the outer drum 141 and are discharged through the discharge plate 2 233.

[0047] Step 3: During the stirring process, a part of the smaller mineral particles fall into the middle drum through the sieve hole 3 182 of the inner drum, and then fall into the outer drum 141 through the sieve hole 2 174 of the middle drum, and finally enter the aggregate sleeve 15 through the sieve hole 1 1411 of the outer drum 141, and are first discharged from the discharge plate 151. During the stirring process, a small amount of ore particles are blocked in the sieve hole 1411 of the outer drum 141, affecting the smooth discharge of the smaller mineral particles. During this period, the vibration motor 224 drives the vibration plate 222 to vibrate up and down, and the top hole rod 223 on the vibration plate 222 squeezes the ore particles blocked in the sieve hole 1411, so that it enters the outer drum 141 again for screening, and at the same time, the filtered water in the water tank 212 is transported to the storage tank through the water pump 215 and the water pipe 214. The water in the water box 216 is sprayed out through the water spray head 217 to impact the sieve hole 1411 of the outer drum 141, and the ore particles blocked in the sieve hole 1411 are squeezed. With the cooperation of the water pressure and the squeezing force of the top hole rod 223, it is ensured that the ore particles blocked in the sieve hole 1411 of the outer drum 141 are squeezed into the outer drum 141 again to avoid affecting the screening effect of the sieve hole 1411 of the outer drum 141. The size of the sieve hole 1411 of the outer drum 141 is smaller than the sieve hole 2 174 of the middle drum 173, and the sieve hole 2 174 of the middle drum 173 is smaller than the sieve hole 3 182 of the inner drum 181. Since the larger the size of the sieve hole, the smaller the possibility of clogging the sieve hole, the clogging of the sieve hole 2 174 of the middle drum 173 and the sieve hole 3 182 of the inner drum 181 can be ignored.
