Feeding structure for preparing ethylene sulfite

The utility model discloses a feeding structure for preparing ethylene sulfite, which relates to the technical field of ethylene sulfite preparation and comprises a stirring bin, material collecting boxes are fixedly arranged at the bottoms of two sides of the stirring bin, and a suction pump is fixedly arranged on one side of the top end of each material collecting box. Two suction pumps are arranged in the two material collecting boxes, the liquid suction ends of the two suction pumps are communicated with the interiors of the two material collecting boxes through liquid suction pipes respectively, and the liquid outlet ends of the two suction pumps are connected with telescopic hoses through the liquid suction pipes. Then a reciprocating motor is started to drive a connecting lead screw to rotate, the connecting lead screw rotates to enable a discharging bin to slide in a reciprocating mode along the inner wall of a first sliding groove, impurities can be rapidly screened out through a filter screen, meanw
