In this embodiment, as shown in fig. 2, an integrated apparatus for crushing and screening molybdenum ore with high efficiency further includes a first motor 320, the first motor 320 is disposed in the return cylinder 310, and an output shaft of the first motor 320 is fixedly connected to an upper end of the long spiral lifting 330.
In this embodiment, a high-efficiency crushing and screening integrated device for molybdenum ores further includes a second motor, the second motor is disposed in the supporting shell 110, and an output shaft of the second motor is connected with the special main shaft 410.
In this embodiment, as shown in fig. 5, a conical crushing cavity is provided at the feed cylinder 120, and the conical portion is engaged with the conical crushing cavity.
In this embodiment, as shown in fig. 1, a discharge port 130 is provided at the bottom of the support housing 110. While the small pieces of ore that have met the requirements will drop into the lowermost chamber through the vibrating screen deck fine screen 430, rotate and eventually drain from the discharge opening 130 under the action of the third spring paddle 443.
In operation, in an initial state, coarse screen 420 is in contact with first metal contact 111 and fine screen 430 is in contact with third metal contact 113. Long spiral lift 330 and short spiral lift 340 do not mate and are spaced apart.
The second motor is started and the special main shaft 410 starts to rotate around its own axis, and the crushing cone 210 starts to swing eccentrically due to the tilting shaft guide 413. Bulk molybdenum ore is fed into the support housing 110 from the feed cylinder 120, the bulk molybdenum ore falls into the gap between the feed cylinder 120 and the crushing cone 210, and the crushing cone 210 circumferentially crushes the molybdenum ore in the gap.
The crushed ore moves downward from the gap between the feed cylinder 120 and the crushing cone 210 and falls onto the coarse screen 420 of the screening plate, at this time, the spring support 450 is compressed, the coarse screen 420 moves downward, the first link 351 moves downward, the gear 352 is driven to rotate, and the link is further driven to move upward, and the long spiral lifting 330 is driven to move upward. Since the first spring deflector 441 follows the circumferential rotation of the special spindle 410, small pieces of ore and medium-sized ore drop down from the holes of the coarse screen 420 under the pushing of the first spring deflector 441, and large pieces of ore are pushed in the direction of the long spiral lifting 330 during the rotation. The first motor 320 is activated to rotate the long screw lift 330, and under the action of the long screw lift 330, the large lump ore is transported to the upper end of the long screw lift 330 and is crushed again after being transported into the feed cylinder 120 again through the discharge port 460.
Medium ore falls onto fine screen 430 and is temporarily stored on fine screen 430 until the large pieces of ore on coarse screen 420 are processed. During this process, more and more medium ore falls into the fine screen 430, and the ratchet ring 411 rotates with the special spindle 410 under the action of the ratchet ring 411, so that the fine screen 430 starts vibrating. After which a portion of the small-sized ore drops, and the small pieces finally reach the bottom of the support housing 110 through the fine screen 430, the medium ore gradually accumulates on the fine screen 430, the fine screen 430 is pressed to gradually move downward, and the first spring is compressed. The fine screen 430 moves downward and the short spiral lift 340 gradually moves upward by the second link 361. Long spiral lift 330 and short spiral lift 340 remain out of contact.
After the large piece of ore on the coarse screen 420 is processed, the compressed spring supporting plate 450 is released, the coarse screen 420 returns to the initial position to be in contact with the first metal contact 111, the first connecting rod 351 moves upwards, the gear 352 is driven to rotate, the connecting frame is further driven to move downwards, and the long spiral lifting 330 is driven to move downwards. Finally, the matching block on the long spiral lifting 330 is inserted into the matching opening 342 on the short spiral lifting 340, the lower end of the long spiral lifting 330 is contacted with the fifth metal contact 341, and the circuit of the fifth metal contact 341 is connected with the internal coil forming electromagnet of the fifth metal contact 341, so that the connection between the short spiral lifting 340 and the long spiral lifting 330 is tightly fixed. While the mating port 342 is responsible for torque transfer, the long spiral lift 330 and the short spiral lift 340 form a single unit. Short spiral lift 340 is rotated by long spiral lift 330 and conveys the medium ore in the corresponding chamber of fine screen 430 back to feed cylinder 120.
At this time, the fine screen 430 contacts the fourth metal contact 114, the coarse screen 420 contacts the first metal contact 111, the fourth metal contact 114 and the first metal contact 111 are simultaneously connected, and the hydraulic pump continues to pump a fixed hydraulic chamber 230 with a fixed volume of liquid, which lifts the crushing cone 210 up by one unit, reducing the distance between the crushing mechanism 200 and the crushing cone 210, increasing the crushing precision, and crushing medium-sized molybdenum ore into small pieces of molybdenum ore until the introduced raw material is completely processed. While the small pieces of ore that have met the requirements will drop into the lowermost chamber through the vibrating screen deck fine screen 430, rotate and eventually drain from the discharge opening 130 under the action of the third spring paddle 443.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
