A universal filter for amination reactions
ActiveCN224270348UReduce the frequency of removal and cleaningeasy to collectStationary filtering element filtersMechanicsAmination
This utility model discloses a universal filter for amination reactions, belonging to the field of filter technology. The filter includes a tank, a cover, and a filter basket. A first pipe is connected to the tank, and a second pipe is connected to the cover. The filter basket divides the internal space of the tank into a first working space and a second working space. The filter basket includes an annular plate and a bottom plate, with a receiving container on the bottom plate. Liquid in the first working space enters the second working space after being filtered by the filter basket. The receiving container protrudes towards the second working space. This utility model, by providing a receiving container on the filter basket, facilitates the collection of some trapped particles, reduces particles retained on the filter basket, reduces the possibility of particles getting stuck in the filter holes, and reduces the frequency of the filter basket needing to be removed for cleaning. A baffle covers the receiving container, reducing the direct impact of the liquid flow on the internal cavity of the receiving container. The baffle and connecting rod are detachably connected, facilitating the collection of particles inside the receiving container.

PendingCN120016988AMultiple-port networksLogic circuits characterised by logic functionCapacitanceCMOS
The invention discloses a filter. The filter comprises an original filter assembly and a potential translation branch. The original filter assembly comprises a target capacitor. And the potential translation branch is configured to increase or decrease the output voltage of the original filter component within a preset range so as to control the target capacitor to always work in a linear region. According to the filter provided by the embodiment of the invention, the output voltage of the output end of the filter can be increased or reduced by arranging the potential translation branch circuit on the basis of a universal filter circuit structure adopting the CMOS capacitor, so that the voltage drop at the two ends of the CMOS capacitor is always kept positive in the whole signal period; therefore, the CMOS capacitor is controlled to always work in a voltage region with good capacitance linearity in the whole signal period, the distortion characteristic of the filter is reduced, and the condition that the distortion of the filter exceeds an allowable range due to the fact that the CMOS capacitor works in a nonlinear region is avoided.
