Abstract

The invention discloses a movable suction filter for pilot test. The movable suction filter comprises a suction filter body and a pedestal. The suction filter body comprises a filter barrel 1, a filter barrel 2 and a filter cloth pressure ring. The filter barrel 1 and the filter barrel 2 are both cylindrical barrels, the bottom plate of the filter barrel 1 is provided with a plurality of filter pores, and an external thread part is arranged at the bottom of the filter barrel 1, the side wall of the filter barrel 1 is equipped with rotating handles symmetrically, the filter cloth pressure ringis mounted at the barrel mouth of the filter barrel 1, and the filter barrel 2 is disposed below the filter barrel 1. The inner wall of the filter barrel 2 mouth is equipped with internal thread fitting the external thread. The device provided by the invention solves the problem that a filter cloth cannot be replaced because of filter cloth blocking in the suction filtration process, and has the advantages of convenience for thorough pumping of filtrate in the filter barrels, safe and environment-friendly suction filtration process, and the like.

Description

technical field [0001] The invention belongs to the technical field of chemical equipment, and in particular relates to a movable suction filter used for a pilot test. Background technique [0002] In the chemical and pharmaceutical process, the intermediate scale-up test is required after the small test. Many reactions in the pilot test process often require suction filtration, such as the racemization reaction process of amino acids. Since the racemization reaction is generally carried out under high temperature and high pressure conditions, the actual production Among them, in order to reduce the production cost and waste liquid treatment pressure, the mother liquid often has to be applied dozens or even hundreds of times before being eliminated, so by-products such as insoluble and viscous polymer aggregates during the reaction will A large amount of accumulation makes the mother liquor too viscous and difficult to filter. In order to study the racemization process in th...
