Description

Technical Field

[0001] The utility model belongs to the technical field of ore cleaning, in particular to an ore cleaning device. Background Art

[0002] Before quartz is made into quartz powder, it needs to be cleaned, graded, and crushed. Existing quartz needs to be classified before cleaning. Different sizes of quartz require different cleaning methods. Smaller quartz is cleaned using a drum with a screen and circulating water. This not only cleans the ore but also separates it from the fine quartz particles. Larger quartz is rinsed with a spray gun and a tumbling device.

[0003] When cleaning smaller quartz stones, existing drums with screens are prone to getting stuck in the filter holes. If not cleaned, this affects the subsequent cleaning efficiency of the drum and also results in waste of quartz stones. Furthermore, manually cleaning quartz stones stuck in the filter holes consumes a lot of manpower and material resources, affecting production efficiency.

[0004] Therefore, a kind of ore cleaning equipment is needed. Utility Model Content

[0005] The purpose of this utility model is to provide an ore cleaning device to overcome the defects of existing drum ore cleaning equipment, which easily causes ore to get stuck in the external filter holes when cleaning ore, thus affecting the subsequent cleaning efficiency of the drum and causing waste of quartz stone.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Next, the working principle of this embodiment is described in detail to enable those skilled in the art to better understand the present invention:

[0024] refer to Figure 1An ore cleaning device includes a motor, a reducer, a drum 1, a drum bracket 2, a cylindrical screen 3, a conveyor belt 4, guide bars 6, a water trough 5, and a circulating vibration unit. The drum bracket 2 is mounted on the ground with anchor bolts, and the drum 1 is rotatably mounted on the drum bracket 2. The motor is connected to the drum 1 via the reducer to drive the drum 1 to rotate. The drum 1 is provided with a feed port and a discharge port. Quartz stone enters the drum 1 through the feed port and is agitated with water inside the drum 1 to clean impurities on the surface of the quartz stone.

[0025] One end of the cylindrical screen 3 is connected to the discharge port, and the cleaned quartz stone and water are discharged from the discharge port. Impurities, water, and fine particles will flow out of the filter holes of the cylindrical screen 3 and fall into the water tank 5 for collection. Multiple guide bars 6 are installed on the inner wall of the cylindrical screen 3 in a circular array around the axis of the cylindrical screen 3. Under the action of the guide bars 6, the quartz stone can move toward the conveyor belt 4. The conveyor belt 4 is installed directly below the other end of the cylindrical screen 3. The cleaned and filtered quartz stone will move to the conveyor belt 4, and then the conveyor belt 4 will move the quartz stone to the color sorter for screening. The circulating vibration unit is installed on the side wall of the water tank 5 to vibrate the drum 1 screen to prevent the ore from getting stuck on the cylindrical screen 3.

[0026] refer to Figure 2 and Figure 3 The cyclic vibration unit includes a support frame 7, a shell 8, a spring 9, a telescopic rod 10 and a triangular block 11. One end of the support frame 7 is mounted on the side wall of the water tank 5 by bolts, and the shell 8 is mounted on the other end of the support frame 7 by bolts. A telescopic hole 801 is opened at one end of the shell 8 facing the cylindrical screen 3, and the telescopic rod 10 is slidably installed in the telescopic hole 801. The spring 9 is installed in the shell 8, and the two ends of the spring 9 are elastically supported by one end of the telescopic rod 10 and the inner wall of the shell 8 respectively. A constraint belt 12 is provided on the cylindrical screen 3, and a plurality of triangular blocks 11 are mounted on the constraint belt 12 in a circular array around the axis of the cylindrical screen 3. The planes of the triangular block 11 that are not in contact with the constraint belt 12 are respectively provided with inclined surfaces and vertical surfaces, and the extension line of the vertical surface passes through the axis of the cylindrical screen 3. The other end of the telescopic rod 10 is continuously in contact with the outer side wall of the constraint belt 12 under the action of the spring 9. When the cylindrical screen 3 rotates, the telescopic rod 10 will contact the inclined surface of the triangular block 11. At this time, the inclined surface increases the distance between the end of the telescopic rod 10 and the axis of the cylindrical screen 3. The telescopic rod 10 will continue to squeeze the spring 9. When the telescopic rod 10 leaves the inclined surface, since the vertical surface will not block the telescopic rod 10, the telescopic rod 10 will move toward the cylindrical screen 3 under the action of the spring 9, and eventually collide with the constraint belt 12, thereby causing the cylindrical screen 3 to vibrate intermittently, preventing the ore from being stuck in the filter holes of the screen, ensuring the overall cleaning efficiency of the cleaning equipment, and avoiding waste of ore.

[0027] A roller 13 is rotatably mounted on the end of the telescopic rod 10 away from the spring 9. Under the action of the spring 9, the roller 13 continuously contacts the outer wall of the restraint belt 12. The roller 13 converts the sliding friction between the telescopic rod 10 and the restraint belt 12 into rolling friction, thereby reducing the friction coefficient and avoiding damage to the telescopic rod 10 and the restraint belt 12.

[0028] A threaded hole 802 is formed at the end of the housing 8 away from the telescopic hole 801. An adjustment rod 14 is rotatably mounted within the threaded hole 802. One end of the adjustment rod 14 abuts against the end of the spring 9 away from the telescopic rod 10. The other end of the adjustment rod 14 extends outside the housing 8 and is mounted with a handle 15. Depending on the situation, the spring 9 can be squeezed in advance by rotating the handle 15, thereby adjusting the impact force generated when the telescopic rod 10 collides with the restraining band 12, and thus adjusting the vibration amplitude of the cylindrical screen 3. This allows the device to adapt to different specifications and types of ores, increasing the practicality of the present application.

[0029] A platform 16 is provided at one end of the triangular block 11 away from the restraining belt 12 to prevent excessive stress at the corner of the vertical and inclined surfaces when the roller 13 moves to the corner, which could easily damage the triangular block 11. The cyclic vibration units are symmetrically mounted on both sides of the water tank 5. The extension lines of the two telescopic rods 10 pass through the axis of the cylindrical screen 3, and the line connecting the contact points of the two telescopic rods 10 with the restraining belt 12 passes through the axis of the cylindrical screen 3. This arrangement ensures that the forces acting on the cylindrical screen 3 are symmetrical and equal, thus avoiding excessive radial force on the cylindrical screen 3 that could cause bending and deformation of the cylindrical screen 3, and ensuring the service life of the cleaning equipment.

[0030] An elastic block 17 is installed on the vertical surface of the outer wall of the restraint belt 12 close to the triangular block 11. When the elastic block 17 is subjected to force, it will deform and fit the roller 13, thereby reducing the pressure between the roller 13 and the restraint belt 12 when it hits the restraint belt 12, avoiding damage to both.

[0031] The foregoing descriptions of specific exemplary embodiments of the present invention are for the purpose of illustration and description. These descriptions are not intended to limit the present invention to the precise form disclosed, and it is obvious that many changes and variations can be made based on the above teachings. Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not limitations on the present invention.
