定量设备在砂处理系统中占重要地位。我厂根据铸件生产的需要,将辗轮式混砂机改装后混树脂砂,起初沿用容积式定量斗配砂,由于定量准确性差,造成树脂砂质量不稳定,操作难于掌握。针对这个情况,制作了杠杆秤,并与定量斗组装在一起,做成杠杆秤称量器。其结构如图1。 Quantitative equipment in the sand processing system occupies an important position. I plant according to the needs of casting production, the modified wheel-type sand mixer modified resin sand, initially used volumetric quantitative bucket with sand, due to poor quantitative accuracy, resulting in unstable resin sand quality, operation is difficult to grasp. In response to this situation, the production of a lever scale, and quantitative bucket assembly together, made of lever scale weighing device. The structure shown in Figure 1.
