[0016] The specific implementation of the utility model will be described below in conjunction with the accompanying drawings:
[0017] like Figure 1As shown, a kaolin screening system includes a feeder 1, a mixer 3, a spiral sand remover 5, a water tank 7 and a hydrocyclone 6. The top of the feeder 1 is open, and a discharge port is provided at the bottom near one end of the feeding device 2. The feeder 1 is provided with a spiral stirring blade. The shovel truck pours the kaolin ore directly into the silo of the feeder 1 from the top of the feeding port, and the motor drives the spiral stirring blade to rotate and discharge the kaolin ore from the discharge port continuously and stably. The feeder 1 and the mixer 3 are connected through the feeding device 2. The feeding device 2 includes a conveyor belt, a driving motor and a tension roller. One end of the conveyor belt is connected to the discharge port, and the other end is connected to the feed port of the mixer 3. The kaolin ore is poured from the discharge port onto the conveyor belt and transported to the feed port of the mixer 3 along the conveyor belt. The kaolin ore is stirred with water in the mixer 3 to form a slurry, so that the kaolin ore is separated from the hard impurity particles. A cylindrical screen 4 is provided between the mixer 3 and the spiral desander 5. The cylindrical screen 4 is provided with a coarse stone discharge port and a fine material discharge port. One end of the cylindrical screen 4 is connected to the discharge port of the mixer 3. The coarse stone discharge port leads to the waste bucket, and the fine material discharge port is connected to the spiral desander 5. The slurry formed by the kaolin ore is separated from the coarse stone impurities of the enlarged block after being filtered by the cylindrical screen 4, and leaves the cylindrical screen 4 through the fine material discharge port, and then enters the spiral desander 5. The slurry is further separated from the smaller impurity particles in the spiral desander 5 to improve the purity of the slurry. A sand collecting trough is provided at one end of the bottom of the spiral desander 5, and a first sand discharge port that can be opened and closed is provided at the bottom of the sand collecting trough. The main component separated from the slurry is quartz sand, which is deposited in the sand collecting trough. When the quartz sand reserves in the sand collecting trough are large, the first sand discharge port is opened to collect the quartz stone, which can be sold as a by-product. The discharge port of the spiral desander 5 is connected to the feed port of the hydrocyclone 6, and the purified slurry passes through the discharge port and enters the hydrocyclone 6. The feed port of the hydrocyclone 6 is connected to the mud outlet through a pipeline, and the discharge port of the hydrocyclone 6 leads to the storage tank; a second sand discharge port is provided at the bottom of the hydrocyclone 6. The slurry undergoes the last step of separation and purification in the hydrocyclone 6, and the fine sand contained in the slurry is discharged from the second sand discharge port, and the separated kaolin coarse ore slurry flows into the storage tank through the discharge port. The water tank 7 is connected to the mixer 3, the spiral desander 5 and the hydrocyclone 6 through water pipes. The water tank 7 centrally supplies water to the mixer 3, the spiral desander 5 and the hydrocyclone 6, and each water supply pipeline is independent of each other to ensure stable water supply. Each water supply pipeline is equipped with an independent water pump to meet the water supply needs of different equipment.
[0018] The working principle of the specific implementation mode of the utility model is as follows: the kaolin ore is continuously and stably fed to the subsequent equipment through the feeder 1 and the conveyor belt, the kaolin ore is mixed with water in the mixer 3 to form a slurry, and the slurry is sequentially separated and purified by the multi-stage separation of the cylindrical screen 4, the spiral sand remover 5 and the hydrocyclone 6, so that the kaolin ore is separated from the impurity particles contained therein, and finally the kaolin coarse ore slurry is obtained in the storage tank.
