一、概况电磁振动筛用于铸造车间筛分旧砂和新砂,筛子上下振动,频率可以调节。我厂铸造车间用于筛分旧砂,芯头、铁块及其他杂物由筛上自行流出。振动筛装置的示意图如图1所示。抓斗把旧砂送入储砂斗,旧砂从下端出口自动流入振动筛,筛好的砂子由提升机送入混砂机。筛子四角通过四个弹簧悬于储砂斗下。衔铁靠拉杆固定于筛子上,电磁铁由支架固定在地面上。当电磁铁线圈通电时,引动衔铁,拉筛子向下运动;断电时,四个弹簧拉筛子向上运动。这样,不断通电、断电,实现筛子上下 First, an overview of the electromagnetic vibrating screen for casting workshop screening of old sand and new sand, the screen vibration up and down, the frequency can be adjusted. Our foundry workshop for screening of old sand, core head, iron and other debris by the screen out on their own. Schematic diagram of shaker device shown in Figure 1. Grab the old sand into the sand storage bucket, the old sand from the bottom outlet automatically into the shaker, sieve good sand by the elevator into the sand mixer. The four corners of the screen are suspended by four springs under the hopper. The armature is fixed on the sieve by the pull rod, and the electromagnet is fixed on the ground by the bracket. When the electromagnet coil is energized, the armature is pulled and the sieve is pulled downwards. When the power is off, the four springs pull the sieve upwards. In this way, continuous power, power, to achieve sieve up and down
