宜昌纺织机械厂铸造车间在回砂系统安装了一台外购的直线筛,筛片定做,材料为14～16号镀锌铁丝,筛眼方孔为15mm×15mm 或20mm×20mm,按季节区别使用。如图所示,安装时筛片用螺丝将压板和拖板紧固,然后拉紧拉杆即可。回砂时砂量多冲击力大,换上的筛片使用一星期左右便从托板端头处切断,既浪费了材料,又增加了维修工人的工作量。 Yichang Textile Machinery Factory casting workshop in the sand back system installed an outsourced linear sieve, sieve custom, the material is 14 to 16 galvanized iron wire, sieve square hole is 15mm × 15mm or 20mm × 20mm, according to the season to use . As shown in the picture, install the sieve with screws to tighten the platen and carriage, and then tighten the lever. When the sand back to sand and more impact, replace the sieve using a week or so from the end of the pallet cut off, both waste of materials, but also increased the workload of maintenance workers.
