Problems solved by technology
Over time, these materials stuck in the sieve holes will cause the sieve plate sieve holes to be blocked, which will reduce the sieve penetration rate of the sieve plate, thereby reducing the screening efficiency and causing huge economic losses.

The invention discloses a high-elasticity anti-blocking polyurethane sieving plate. The sieving plate is internally provided with a rigid framework shaped like a Chinese character 'tian', a space areaof the rigid framework shaped like the Chinese character 'tian' is divided by steel wire ropes, the sieving plate is externally provided with a polyurethane elastic sieving surface, a plurality of long-strip-shaped sieving holes arrayed vertically and horizontally at preset intervals are formed in the polyurethane elastic sieving surface, an opening of each long-strip-shaped sieving hole is an inverted bell mouth with the small upper part and the large lower part, and when materials are stuck in the sieving holes, the sieving holes in the sieving plate can deform and expand towards the two sides through vibration work of a sieving machine, so that the materials fall down to prevent the sieving plate from being blocked and improve the sieving efficiency. The invention further discloses a manufacturing method of the high-elasticity anti-blocking polyurethane sieving plate and the sieving machine.
Description
technical field [0001] The invention relates to the technical field of screening machines, in particular to a highly elastic anti-clogging polyurethane sieve plate, a screening machine and a manufacturing method of a high elastic anti-clogging polyurethane sieve plate. Background technique [0002] China is rich in coal resources. Coal washing can improve coal quality, reduce coal-burning pollutant emissions, improve coal utilization efficiency, save energy, optimize product structure, improve product competitiveness, and reduce waste of transportation capacity. Among them, the ground coal processing system consists of coal receiving, screening, crushing, coal preparation, storage, loading and other major links. Sieving is the operation of dividing mixed materials with different particle sizes into various particle sizes by using a screen surface with holes. [0003] At present, the grading sieve plates used in the screening and grading equipment in the washing industry are...
