Description

Technical Field

[0001] The utility model relates to the technical field of dewatering screens, in particular to a dewatering screen for ore dressing. Background Art

[0002] In the mineral processing process, the dehydration link is crucial to improving the efficiency of the entire process and the quality of the final output materials. As a core mining equipment, the main function of the mineral processing dehydration screen is to remove excess water from the ore through effective separation technology after the ore has undergone preliminary physical treatment, such as crushing and grinding. This step can significantly improve the efficiency of subsequent processing links. According to the physical characteristics of the ore and the different processing requirements, the parameters such as the screen material, aperture size and vibration mode of the dehydration screen need to be precisely designed and adjusted to ensure its optimal performance in the mineral processing process.

[0003] The patent with publication number CN215387995U discloses a dewatering vibration screen, including an upper frame, a filter plate for filtering material moisture arranged at the bottom of the upper frame, a driving mechanism fixed on the upper frame for driving the upper frame to vibrate, and a lower frame arranged below the upper frame, wherein the lower frame includes a water collecting bucket and support plates arranged at an angle on both sides of the water collecting bucket, and the height of the support plates gradually increases along the direction from the feed end to the discharge end; the upper frame is arranged above the lower frame through support feet arranged around the lower frame, and the support feet include a plurality of first support feet located at the feed end and a plurality of second support feet located at the discharge end, and the height of the second support feet is greater than the height of the first support feet, and the upper frame is arranged at an angle, and a discharge port is provided at the front end of the upper frame. The dewatering vibration screen of the utility model is an upper and lower structure, and is assembled in a split modular manner, which is convenient for disassembly and assembly, and solves the problem of insufficient dehydration of raw materials.

[0004] The above-mentioned prior art has made certain progress in solving the problem of raw material dehydration. It innovatively adopts the design of split modular assembly of upper and lower structures, which significantly improves the efficiency and convenience of raw material dehydration. However, in the specific implementation process, the installation and replacement operation mode of the filter plate still has certain limitations. Specifically, the design of connecting the filter plate to the frame through hexagon socket bolts is not convenient when replacing the filter plate and there is a potential risk of damage. The replacement process requires the staff to stand directly inside the upper frame and step on other filter plates, which not only poses a threat to the safety of the staff, but also increases the risk of damage to other filter plates. In view of this, we propose a dehydration screen for mineral processing. Utility Model Content
