[0002] In the current soda ash production, the equipment used in the filtration of heavy alkali NaHCO3 is mainly belt filter or vacuum drum filter, etc. Belt filter and vacuum drum filter have obvious disadvantages, such as high energy consumption of vacuum unit in the dehydration process of heavy alkali, high water content of heavy alkali filter cake, which leads to high energy consumption of subsequent heavy alkali calcination, etc. The traditional pusher centrifuge for heavy alkali dehydration has the disadvantages of high leakage rate and high salt content due to insufficient washing.

[0003] The patent application number is CN211964613U, which is a three-stage pusher centrifuge structure with high separation efficiency. The disclosed three-stage pusher centrifuge cannot effectively clean the product filter cake after filtering and centrifuging the filter cake. The centrifuged product filter cake needs to be cleaned separately, which has low working efficiency. If soda ash is processed, it cannot be guaranteed that the salt content of the heavy alkali filter cake meets the production specifications. Therefore, it is urgent for technical personnel in this field to solve the above technical problems. Utility Model Content
