为解决铸造车间中型砂斗斗壁粘结和出口堵塞问题,多年来国内外铸造工作者曾采用了气动和机械振动或电磁振动、压缩空气吹割及斗壁衬不锈钢板、搪瓷板、塑料板等措施,均取得一定成效,但解决得都不够理想。我们通过实践,设计制造了一种料柱分层自击式型砂斗,可使型砂始终保持松散状态,并在砂斗下部产生自击振动,基本上避免了砂斗斗壁粘结 In order to solve the problem of sticking and outlet blockage in medium-sized sand hopper in foundry workshop, over the years, domestic and foreign foundry workers have used pneumatic and mechanical vibration or electromagnetic vibration, compressed air blowing and wall-lining stainless steel plate, enamel plate and plastic plate Measures, have achieved some success, but not enough to solve the ideal. Through practice, we design and manufacture a layered self-impacting type sand hopper that can keep the sand in a loose state all the time and generate self-impact vibration in the lower part of the sand hopper to basically prevent the sand hopper from sticking
