Abstract

The invention relates to the technical field of ore dressing devices, and particularly discloses a screening machine using a polyurethane screen, which comprises a screening machine body, a screen anda fixing part, the screen comprises a support frame body and a screen piece, the support frame body is in a grid shape formed by transverse support bars and longitudinal support bars, and transverseframeworks and longitudinal frameworks are respectively arranged in the transverse support bars and the longitudinal support bars; the screen piece comprises a frame, a plurality of transverse screenbars 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 sections of the upper portions of the screen bars of the transverse screen bars are obtuse triangles, the long edges of the obtuse triangles correspond to the front ends of the lower portions of the screen bars, and the screen piece is integrally formed by thermoplastic polyurethane elastic materials with the hardness of 82-92 Shore A; the support frame body and the screen piece form an integral structure by adopting secondary pouring,and the support frame body is made of a TDI system two-component polyurethane material; the fixing part is used for flexibly fixing the screen on the screening machine body; the problems that an arc-shaped screening machine is short in service life, high in maintenance cost 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 screen machine using a polyurethane screen. Background technique [0002] Curved sieve is an economical and practical solid-liquid separation equipment, mainly used in coal preparation plants and mineral processing plants for pre-dehydration, desliming, deintermediation operations, classified coal slime recovery, and can also be matched with hydrocyclones It is used to effectively classify, dehydrate, deslim and remove medium for fine-grained materials. At present, most of the curved screens are assembled and welded with stainless steel sieve bars, and the cutting edges of the stainless steel sieve bars are used to divide the slime water to achieve the purpose of improving the dehydration and mediation effect. In the actual application process, in order to solve the problem of non-wear resistance of stainless steel screens, wear-resistant steel screen bar ma...
