Detailed description of the invention
Comminutor impeller feeder as depicted in figs. 1 and 2, its structure comprises body 1, impeller, drive motors 10 and feeding cavity, feeding cavity is placed in body 1, the upper-lower position of feeding cavity has charging aperture 3 and discharging opening 2, impeller is placed in feeding cavity, and drive motors 10 is placed in and comprises on body 1; Also be provided with arrangements for speed regulation in body 1, arrangements for speed regulation are connected with drive motors 10.Described arrangements for speed regulation comprise frequency converter and power supply, and frequency converter is made up of rectifier 13 and inverter 12, and rectifier 13 is connected with power supply, and inverter 12 is connected with drive motors 10.First the material needed for pulverizer is put into from the charging aperture 3 feeding cavity during work, rotated by drive motors 10 impeller, material is flowed to pulverizer from discharging opening 2.The present invention is the adjustment realizing wheel speed by frequency control, alternating current is become direct current by rectifier 13 by frequency converter, level and smooth wave circuit is level and smooth by direct current, DC inverter is the alternating current of frequency-adjustable by inverter 12, realizes the adjustment to impeller speed by change power frequency.
Feeding cavity is as shown in Figure 1 divided into left chamber 14 and right chamber 15, described impeller is made up of the first impeller 7 and the second impeller 9, first impeller 7 and the second impeller 9 are placed in left chamber 14 and right chamber 15 respectively, also be provided with crushing wheel 6 in described left chamber, crushing wheel 6 is positioned at the below of the first impeller 7.Be connected to screen 8 by rotating mechanism 16 in described body 1, screen 8 is positioned at above left chamber 14 and right chamber 15, screen 8 has through hole 17.Described rotating mechanism 16 comprises rotating disk, gag lever post and horizontal block, and horizontal block is located on rotating disk; One end of gag lever post is connected with rotating disk, and the other end is connected with screen 8.When material drops to screen 8 from charging aperture 3, less material can drop from the through hole 17 screen 8 into
In left chamber 14 as shown in Figure 1 and right chamber 15, flow to pulverizer by wheel rotation; Larger material can rest on screen 8, now rotary turnplate, allows gag lever post deflect with screen 8, thus larger material is flowed in left chamber 14, after larger material becomes less material by the pulverizing of crushing wheel 6, then flows to pulverizer.This structure has the ability distinguishing size material, and larger material can be pulverized in advance, prevents the generation of putty.
