Description

Technical Field

[0001] The utility model relates to the technical field of ore dressing equipment, in particular to an ore dressing equipment that can prevent blockage. Background Art

[0002] The main function of ore dressing equipment is to effectively separate the useful minerals in the ore from the useless minerals or other impurities, so as to improve the grade and recovery rate of the ore, and then enhance the economic benefits of the entire mining enterprise. At the same time, it can greatly improve the production efficiency, reduce the labor cost, reduce the downtime due to faults, and ensure the continuity and stability of production.

[0003] However, at present, during the ore screening process, only a set of separation structures are often installed inside the ore dressing equipment, which results in often insufficient screening effect when screening the ore. In addition, when these equipment screen the ore, the screen is often blocked by the ore, which not only affects the screening efficiency but also reduces the practicability of the equipment.

[0004] Therefore, aiming at the situation that the screen of the above ore dressing equipment is often blocked by the ore during the ore screening process, which in turn leads to a reduction in the screening efficiency, an ore dressing equipment that can prevent blockage can be designed. Through the gear transmission structure and the vibration structure, while the ore is being double-vibration screened, the problem of screen blockage is effectively prevented.

[0027] Please refer to Figure 6, in this embodiment, the screening assembly includes a support plate 901, a spring 902 and a sieve plate 903; the support plates 901 are symmetrically and fixedly connected to the inner wall of the screening box 4 from left to right, the support plate 901 on the right is higher than the support plate 901 on the left, and symmetric springs 902 are installed at the upper ends of each support plate 901. The upper end of each spring 902 is fixedly connected to a sieve plate 903. The screening assembly further includes a vibration motor 904, a sieve mesh 905 and a second material guiding frame 906; there are two vibration motors 904 and they are installed at the lower right side of each sieve plate 903.

The second material guiding frame 906 is located above the uppermost sieve plate 903. The screening assembly further includes a waste outlet 907 and a waste collection box 908; the waste outlet 907 is opened on the screening box 4 and is located at the left end of each sieve plate 903.

The support plate 901 is the support structure of the screening assembly, providing a stable support platform for the sieve plate 903. The support plate 901 on the right is higher than the support plate 901 on the left. This design helps to form an inclined screening surface, enabling the ore to move downward naturally during the screening process. The main function of the spring 902 is to transmit vibration. When the vibration motor 904 operates, they will absorb part of the vibration energy and transmit the remaining vibration energy to the sieve plate 903, causing the sieve plate 903 to generate high-frequency vibration, thereby promoting the screening of the ore.

Subsequently, the servo motor 802 is started, and the motor quickly drives the first crushing shaft 805 to rotate. Through the gear meshing mechanism, the synchronous rotation of the second crushing shaft 806 is triggered. These two shafts respectively drive the crushing teeth 807 thereon to rotate flexibly, jointly performing an efficient crushing operation on the ore;

[0029] The crushed ore particles then smoothly enter the screening box 4 through the connecting pipe 5. At this time, the vibration motor 904 is activated, and the power it generates causes the two sieve plates 903 to vibrate rhythmically. Under this vibration effect, the ore and impurities are effectively separated. The ore particles that meet the specifications easily pass through the sieve mesh 905 and fall into the discharge pipe 7 below for the staff to collect. The impurities intercepted by the sieve mesh 905 gradually roll down to the waste outlet 907 during continuous vibration and finally fall into the collection box 908, waiting for the staff to carry out subsequent processing.

[0030] Through the above steps, through the collaborative operation of the crushing component and the screening component, the large ore pieces are finely crushed into suitable small particles, making the subsequent screening process smoother. At the same time, it can accurately and efficiently separate the crushed ore from the impurities mixed in it, thus ensuring the high quality of the screened ore.
