For example, in the synthesis process of 7-ACCA (which is an important intermediate for synthesizing second-generation cephalosporin, namely cefaclor and the like), dilute hydrochloric acid and sodium hydrosulfite need to be synchronously dripped in the reaction process, and the temperature and the pH value of the reaction system are controlled by controlling the addition speed of the two materials. In the adding process of the sodium hydrosulfite, the sodium hydrosulfite is connected with a charging hole on the reaction kettle through a charging hopper, and then the sodium hydrosulfite is poured into the charging hopper ceaselessly by one person standing at a high place. Because sodium hydrosulfite state is dry powder, when reinforced, the dust is great, and operational environment is abominable, and face guard and gauze mask need be worn to operating personnel, but also can not avoid the dust at systemic adhesion: in addition, the sodium hydrosulfite is easy to absorb oxygen and oxidize when exposed in the air, and simultaneously is easy to absorb moisture and heat to deteriorate, can capture oxygen in the air to agglomerate and generate irritant sour taste, and can react strongly with water to combust. When 7-ACCA is synthesized, the solvent used in the reaction system is distilled water, water vapor can rise along the feeding port and contact with sodium hydrosulfite, the sodium hydrosulfite can be decomposed, the phenomenon that the pipeline is blocked by agglomeration can occur, and fire can be caused in serious cases, so that the danger is high.
In the prior art, a common stainless steel funnel is adopted for feeding during workshop production, and in order to prevent blockage, an operator feeds materials and uses a tool to pass through a blanking port at the same time, so that blockage is avoided.
