Abstract

The invention relates to the technical field of ore dressing devices, and particularly discloses a polyurethane arc-shaped screen which is characterized in that a supporting frame is of a latticed structure composed of transverse supporting strips and longitudinal supporting strips, and transverse frameworks and longitudinal frameworks are embedded in the transverse supporting strips and the longitudinal supporting strips respectively; a screen piece comprises a frame, a plurality of transverse screen bars and a plurality of longitudinal screen bars, the transverse screen bars and the longitudinal screen bars are connected to the inner edge of the frame, the bottom ends of the transverse screen bars are fixedly clamped in the connecting grooves, and the two ends of each transverse screen bar are perpendicularly and fixedly connected to the two side walls of an inner cavity of the frame respectively. The cross section of the upper portion of each screen strip is in an obtuse triangle shape, the lower surface of the upper portion of each screen strip is flush with the upper surface of the frame, the screen pieces are integrally formed through thermoplastic polyurethane elastic materials, the supporting frame body and the screen pieces form an integral structure through secondary pouring, and the supporting frame body is made of polyurethane materials. The problems that a screen for an arc-shaped screen is short in service life and low in screening efficiency are solved.

Description

technical field [0001] The invention relates to the technical field of mineral processing devices, in particular to a polyurethane arc screen. Background technique [0002] The arc screen is an economical and practical solid-liquid separation equipment, which is mainly used for pre-dehydration, desliming, de-intermediation, and classification of coal slime recovery in coal preparation plants and mineral processing plants. It can also be matched with a water cyclone. It is used to effectively classify, dewater, deslime and de-intermediate fine-grained materials. At present, most of the arc screen meshes are welded by stainless steel screen bars, and the cutting edges of the stainless steel screen bars are used to divide the coal slime water to achieve the purpose of improving the effect of dehydration and deintermediation. In the actual application process, in order to solve the problem that stainless steel screens are not wear-resistant, wear-resistant steel screen material...
