Description
Technical Field
The utility model belongs to the technical field of the pressure filter, specifically speaking relates to dark flow flowing back filtrating viewing device.
Background
The filter press is a main device for solid-liquid separation, the filter plate is a filter element arranged on the filter press, when in filtering, materials enter the filter chamber through the filter plate feeding hole, particles in the materials are retained in the filter chamber through filter cloth arranged on the filter plate to form a filter cake, and filtrate is discharged from the filter plate liquid outlet hole, so that the purpose of solid-liquid separation is realized; the discharge of filtrate through the filter plate liquid outlet holes is divided into two forms according to the industry requirements: one is open effluent, namely filtrate is discharged from a water nozzle arranged on a filter plate and enters a liquid discharge tank; the other is dark effluent, and the filtrate is discharged from the corner holes of the filter plate and enters a liquid discharge pipeline.
The filter cloth is a quick-wear part for filtering of the filter press, and if the filter cloth is damaged, the material loss is caused, so that the filtering effect is reduced; and the filter press adopting the blind flow liquor drainage mode has the advantages that filter cloth damage occurs, material leakage cannot be found in time, the filtering effect is reduced, the filter plates must be opened to check one by one, the damaged filter cloth can be found out and then replaced, and the working efficiency is low.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a dark flow flowing back filtrating viewing device in order to solve the shortcomings existing in the background technology.
The dark flow drainage filtrate observation device comprises: the main body, the transparent plate, the buoy and the bolt; the main body is provided with a liquid inlet, a liquid outlet and a buoy groove; the buoy groove is arranged in the middle of the main body, the liquid inlet hole is arranged at the bottom of the inner side of the main body and connected with the buoy groove, the liquid outlet hole is arranged at the top of the main body and connected with the buoy groove, the buoy is placed in the buoy groove, the transparent plate is attached to the main body and covers the buoy groove, a plurality of bolts are arranged to penetrate through the transparent plate and the main body and fastened on the side face of the filter plate, the filter plate is provided with filtrate holes, and the liquid inlet hole of the main body is aligned with the filtrate holes arranged on the; the pipeline is arranged to connect the liquid outlet hole and the dark flow liquid drainage pipeline.
