Description

Technical Field

[0001] The utility model belongs to the technical field of current collector forks, and in particular relates to a current collector fork device for a central disk of a concentrator. Background Art

[0002] The mine's main products are gold, copper, iron, and sulfur. Currently, eight concentrators are in operation. Concentrators are a key component of the dehydration system, used for dehydrating concentrates and tailings backfill in the concentrator. A concentrator is a device with a central cylinder as a fixed base, and the frame rotates in one direction continuously for 24 hours. However, three unavoidable phenomena have occurred during the operation of the concentrators at this mine.

[0003] First, the particle size of the concentrate product is very fine, and the temperature difference is large when entering the concentrator, and the fine-particle slurry is easily evaporated with water.

[0004] Second, the copper concentrate defoaming device continuously uses water to impact the liquid surface of the concentrator, causing water mist to fly around the machine body.

[0005] Third, sulfur concentrate is highly corrosive, sticking to equipment and corroding spare parts. The concentrator slurry is highly volatile, operating in a harsh environment, and the central collector frequently malfunctions.

[0006] At present, the center collector ring adopts HXTS type sliding wire and JD type collector. HXTS type sliding wire is connected by two or more arcs to form a closed circle. Because the size of mine thickeners is very small, the center disk collector device is also very small, and the collector moves around the circle. As a result, the use of HXTS type sliding wire with JD type collector requires relatively high installation accuracy. It is difficult for general technicians to meet the installation requirements. Therefore, a fork device that can flexibly adjust the position of the collector is needed to eliminate the slide installation accuracy error.

[0007] The pull fork in the existing technology generally consists of a U-shaped support arm and two hinges. When used with the HXTS type sliding line structure, it is difficult to position the pull fork on the collector. The contact between the pull fork support arm and the collector is squeezed and worn in a short time, resulting in an uneven contact surface. The support arm loses its mobile adjustment function. The joint is particularly prone to deformation when subjected to force, resulting in a mismatch between the force direction of the collector and the running direction, causing friction and wear between the collector and the slide. The above problems lead to frequent breakage and replacement of the collector, long-term corrosion failure of the pull fork, excessive running resistance of the pull fork and deformation of the fork. These problems lead to high costs for the use of the collector and the pull fork, seriously affecting the efficiency of the concentrator. Therefore, it is necessary to improve the existing collector pull fork device. Utility Model Content
