The ore to be cleaned which is put into the feed hopper 2 has different granularity, wherein ore particles with larger granularity possibly exist, and the subsequent production requirements cannot be met, so that the ore is crushed and sieved to ensure that the particle sizes of the ore are uniform and are in a certain particle size range, and the ore can be effectively recycled. In order to crush and screen ores while cleaning so as to unify the sizes of ore particles and meet the subsequent use requirements, further, as shown in fig. 2, 3, 8 and 9, the ore cleaning and separating device further comprises a crushing and screening mechanism 7 installed in the feed hopper 2, the crushing and screening mechanism 7 is installed above the ore separating mechanism 3, the crushing and screening mechanism 7 comprises a screen bucket 71 and a filter bucket 72 which are in sliding connection, two first crushing cones 711 are oppositely fixed at the bottom in the screen bucket 71, a plurality of filtering holes 722 are formed in a filter plate 721 of the filter bucket 72, a second crushing cone 723 is fixed on the upper surface of the filter plate 721, the filter plate 721 of the filter bucket 72 is installed below the screen bucket 71 and covers the lower opening of the screen bucket 71, and the second crushing cone 723 extends into the bottom of the screen bucket 71 and is located between the two oppositely arranged first crushing cones 711.
When the sieve hoppers 71 and the filter hoppers 72 slide relatively, the distance between the first crushing cone 711 and the second crushing cone 723 changes, and the ore falling into the sieve hoppers 71 is crushed by the first crushing cone 711 and the second crushing cone 723. As shown in fig. 8 and 9, when the screen bucket 71 slides rightward with respect to the filter bucket 72, the first crushing cone 711 positioned on the left side of the screen bucket 71 moves toward the second crushing cone 723, the distance between the first crushing cone 711 and the second crushing cone 723 on the left side decreases, and the ore positioned between the first crushing cone 711 and the second crushing cone 723 on the left side in the screen bucket 71 is crushed; when the screen bucket 71 slides leftward with respect to the filter bucket 72, the first crushing cone 711 located on the right side of the screen bucket 71 moves toward the second crushing cone 723, the distance between the first crushing cone 711 and the second crushing cone 723 on the right side decreases, and the ore located between the first crushing cone 711 and the second crushing cone 723 on the right side in the screen bucket 71 is crushed. The ore crushed by the crushing cone falls into the filter bucket 72 through the filter holes 722 on the filter plate 721, and the ore entering the filter bucket 72 falls onto the ore separating mechanism 3.
Further, as shown in fig. 8 and 9, the tapered portion of the first crushing cone 711 faces the second crushing cone 723, and tapered portions are provided on both sides of the second crushing cone 723, and the tapered portions on both sides face the first crushing cone 711 on both sides thereof, respectively. As shown in fig. 8 and 9, the first crushing cone 711 and the second crushing cone 723 have a triangular prism shape in cross section, and the second crushing cone 723 has a hexagonal prism shape in cross section.
Further, the pore diameter of the filter pore 722 on the filter plate 721 is 25mm. Ore having a particle size of less than 25mm after crushing falls into the filter house 72 through the filter holes 722.
In order to realize the relative sliding between the sieve bucket 71 and the filter bucket 72, further, as shown in fig. 9, a first telescopic rod 73 and a second telescopic rod 74 are installed in the feed hopper 2, the fixed end of the first telescopic rod 73 is installed in the feed hopper 2, the telescopic end is fixedly connected with the sieve bucket 71, the fixed end of the second telescopic rod 74 is installed in the feed hopper 2, the telescopic end is fixedly connected with the filter bucket 72, and the first telescopic rod 73 and the second telescopic rod 74 drive the sieve bucket 71 and the filter bucket 72 to slide relatively when being telescopic. Further, the first telescopic rod 73 and the second telescopic rod 74 are electric telescopic rods.
Ore enters the sieve bucket 71 from the feed hopper 2, then relative sliding is generated between the sieve bucket 71 and the filter bucket 72 (ore is not thrown into the sieve bucket 71 and the filter bucket 72 from the inside of the feed hopper 2 when the sieve bucket 71 and the filter bucket 72 slide relatively), ore particles with the particle size smaller than 25mm and water are directly filtered into the filter bucket 72 from the filter holes 722, then fall onto the ore separating mechanism 3 below the filter bucket 72 from the filter bucket 72, ore with the particle size larger than 25mm still stays in the sieve bucket 71, and the ore is continuously extruded and crushed through the first crushing cone 711 and the second crushing cone 723 which are close to each other, and falls into the filter bucket 72 from the filter holes 722 when the particle size is smaller than 25mm, and then falls onto the ore separating mechanism 3. Because the screen bucket 71 and the filter bucket 72 move left and right and can play a role in vibration at the same time, the ore particles are prevented from being accumulated and blocked in the screen bucket 71 and the filter bucket 72, and the screening and crushing process of the ore particles is quickened.
Further, as shown in fig. 2, a water tank 63 is installed in the housing 1, the bottom of the water tank 63 is communicated with the drain pipe 52 of the mud-water separator 5, the top is communicated with the water spraying pipe 61, and a water pump 62 is installed at the top of the water tank 63. The water tank 63 is provided to store the waste water discharged from the drain pipe 52 of the sludge-water separation mechanism 5.
In order to filter the waste water discharged from the drain pipe 52 of the sludge-water separator 5 so as to make the water for circularly washing ore cleaner, further, as shown in fig. 2, a waste water filter 64 is installed on the drain pipe 52.
As shown in fig. 3 and 7, further, a spare water tank 64 is further disposed in the housing 1 and is in communication with the water tank 63, and a water injection pipe of the spare water tank 64 extends out of the housing 1. When the water quantity in the water tank 63 is insufficient, water is injected into the spare water tank 64 through the water injection pipe, so that the normal operation of ore cleaning operation is ensured.
When the ore cleaning and separating device of the embodiment is used for cleaning and separating ores, the ores to be cleaned and water for cleaning the ores are thrown into the feed hopper 2, the ores are communicated with water and fall into the sieve hopper 71 of the crushing and screening mechanism 7, the ores in the sieve hopper 71 are crushed by the first crushing cone 711 and the second crushing cone 723 of the crushing and screening mechanism 7, the crushed ores and the water fall into the filter hopper 72 of the crushing and screening mechanism 7, and then fall into the ore separating mechanism 3 from the filter hopper 72, the ore separating mechanism 3 separates the cleaned ores from slurry, the separated ores are conveyed out of the shell 1 by the separating filter plate 31 of the ore separating mechanism 3, the separated slurry enters the mud-water separating mechanism 5 from the discharge hopper 4 for mud-water separation, and the wastewater separated from the slurry is pumped into the water spray pipe 61 by the water pump 62 through the water discharge pipe 52 to flow into the feed hopper 2 again to participate in the cleaning work of the ores.
