Filled filter plate of a disc filter

Abstract

A filled filter plate of a disc filter, relating to a filled filter plate, comprising an outer frame of the filter plate, an inner core is arranged inside the outer frame of the filter plate, and upper and lower inner surfaces of the outer frame of the filter plate Both are equipped with screen plates, and at least one vertical groove is arranged on the upper and lower sides of the inner core, and a plurality of through holes are arranged at intervals between the upper and lower sides of the inner core and the upper and lower sides of the groove. On the upper and lower sides of the core, and along the center line of the inner core, there are multiple groups of bump groups symmetrically arranged left and right. Each group of bump groups includes a plurality of obliquely arranged protrusions. The inner surface of the stencil is in contact with each other, and reinforcing ribs are arranged at intervals in a plurality of through holes. The inner surface of each screen plate is fixedly connected; the present invention has good filtering effect and light overall weight, and is provided with protrusion groups, so that the compressed air distribution is more uniform and fast during reverse blowing, and the cake is fully unloaded.

Description

Technical field [0001] The present invention relates to the field of disc herniation, in particular, to a filling filter plate of a disc filter. Background technique [0002] Understanding, the disc filter is mainly used in a non-ferrous metal industry alumina plant aluminum hydroxide seed liquid, coal industry coal mud and filtration dehydration of various mines; discharged effects of disc filters through vacuum pump The filtered slurry is formed on the filter cloth of the filtered plate, and the filtrate is sequentially discharged from the flow path of the filter cloth, the filter plate, and the central axis, and achieves the purpose of solid-liquid separation. [0003] As the skeleton supporting the filter medium, the filtering effect has a relatively large influence, and the filter plates of the conventional disc filter have two forms: one is the main material of the filter plate is engineering plastic, which is in the filter surface. The strip or circular holes, the filtrate...

AI Technical Summary

Problems solved by technology

Due to the plasticity and light weight of the plastic, the engineering plastic filter plate can be suppressed according to the needs. The internal flow channel structure of the filter plate is highly designable, but the plastic filter plate has a short service life due to its insufficient material strength. Easy deformation and other disadvantages; while the steel filter plate has high strength and is not easy to deform, but its internal flow channel structure design is poor, the hydrophobicity is not good, the filtering effect is not as good as the engineering plastic filter plate, the steel mesh plate is too thick, and the filter plate is heavy. It is very inconvenient to disassemble the filter plate and replace the filter cloth
