Abstract

The invention discloses a material distributing screening machine, comprising a machine case (1), a forced fabric plate (2), a driving device (3), a filtering roller (4), a reducer motor (5) and an iron removing device (24), wherein the machine case (1) is provided with a feeding hole (6) and a plurality of discharging holes (10), the filtering roller (4) comprises a flange disk type roller (11) and a filtering rope type roller (12), the filtering roller (4) is provided with the driving device (3), the reducer motor (5) drives the filtering roller (4) to rotate by virtue of the driving device (3), and material enters from the feeding hole (6), is screened by the filtering roller (4) and is discharged by the discharging hole (10). The invention has the beneficial effects that: more than two materials in different grain sizes can be screened by setting different interstitial screen cuts, the working condition requirement for screening more than two materials can be met, screening efficiency is high, bulk material impact resistance is high, material is distributed more uniformly, no blockage is caused, and an iron piece contained in the material can be removed.

Description

technical field [0001] The invention relates to a coal coarse and fine material separation device, in particular to a cloth screening machine. Background technique [0002] The fuel of circulating fluidized bed boilers in thermal power plants is coal gangue with a certain particle size. The particle size of coal from coal mines is uneven, but most of the materials do not need repeated crushing. These materials generally account for about 35% of the entire material. 75%. If this part of the qualified particle size material directly enters the follow-up crushing equipment without being screened out by the sieve distribution equipment, it will have negative effects on the combustion of the follow-up crusher and boiler in the following aspects: 1. The crusher runs for a long time with overload, The power consumption increases, and the service life of the motor is shortened; 2. The large amount of over-crushing directly affects the combustion efficiency of the boiler; 3. The int...
