Abstract

The invention discloses a filter press for preparing nano cerium oxide. The filter press comprises a rack and a filter press body installed on the rack. A crushing frame is fixed between the inner walls of the rack, the bottom of the crushing frame is connected with a hopper, and a crushing assembly driven by a motor is arranged in the crushing frame. A centrifugal disc is in transmission connection with the crushing assembly, crushing rods which are uniformly arranged are connected to the outer side of the centrifugal disc, and centrifugal rods which are arranged at equal intervals are fixed to the outer side of the bottom surface of the centrifugal disc. A material receiving hopper is restrained below the rack. According to the device, on the basis of a traditional filter press, materials subjected to filter pressing are further crushed, the crushing and dispersing effects can be guaranteed through crushing, and then the recycled raw materials can better meet the actual requirements.

Description

technical field [0001] The invention relates to the technical field of filter presses, in particular to a filter press for preparing nano cerium oxide. Background technique [0002] The filter press uses a special filter medium to apply a certain pressure on the object to make the liquid dialysis out. It is a kind of mechanical equipment commonly used for solid-liquid separation. [0003] The pressure filtration dehydration of cerium oxide is a very important link in its production, and plays a pivotal role in the whole production process. The existing filter press process mainly includes the following links: use the principle of filter cake layer filtration, feed filter, when the feed amount reaches the upper limit and the output liquid is very little, start the diaphragm press to dehydrate, and after the dehydration is completed, unload Remove the filter cake and finally dry it. [0004] However, during blanking, the raw materials after pressing are easily bonded togethe...
