[0001] The invention relates to the technical field of displacement acid filtration, in particular to a synchronous separation filter. Background Art

[0002] In the production of nitrocellulose, the nitration process uses multiple perforated plate displacement acid filters. The filter plates of the filters are made of stainless steel plates with a pore size of 3 mm. The pore size of the filter plates is large, resulting in unsatisfactory filtering effects, and only displacement acids in one concentration range can be filtered separately.

[0003] Common displacement acid filters only include a single filtering function and can filter displacement acids in one concentration range, but lack the function of improving the filtration efficiency and cannot guarantee the efficiency of displacement acid filtration. It is easy to have the problem of only being able to filter displacement acids in one concentration range, affecting the filtration efficiency.

[0004] Therefore, in view of the fact that the above-mentioned replacement acid filter lacks the function of improving the filtration efficiency, a synchronous separation filter can be designed. The first connecting shaft and the driving gear on the left are driven by the reducer to rotate, and the first driving gear on the left drives the transmission chain to rotate, and the transmission chain drives the remaining four driving gears and connecting shafts to rotate. The five rotating connecting shafts synchronously drive the five filter barrels to rotate, and the solid cotton material in the acid is separated at one end through the spiral belt guide in the filter barrel, and each section of the replacement acid is filtered through the filter screens on the five filter barrels to the inner bottom end of the filter box. The automatic and continuous filtration of the five sections of replacement acid ensures the filtration efficiency. Summary of the invention
