Vertical rotary filter

Abstract

The invention discloses a vertical rotary filter. The vertical rotary filter comprises a base plate supported by a support, an outer barrel and a transmission shaft, and the vertical rotary filter is characterized in that the transmission shaft is vertically arranged in the middle of the support, the base plate and the outer barrel through a bearing; a filter liquid distribution valve dynamic disc and a filter liquid distribution valve stationary disc are arranged at the upper end of the transmission shaft; a rotary inner barrel is arranged through the bearing and a wheel hub, a filter leaf bracket is arranged on the outer side of the rotary inner barrel, and a rotary outer barrel is arranged on the outer side of the filter leaf bracket 1; a plurality of square meshed filter leafs are arranged on the filter leaf bracket; a filter liquid outlet pipe is arranged on a corresponding area between every two filter leaves; an externally communicated suspension liquid outlet pipe and an externally communicated concentrated liquid outlet pipe are arranged on the base plate; two or three sealing sector plates are arranged on the base plate at intervals. The machine is simple in structure, small in volume weight, large in filter area, good in effect, high in production capacity, low in investment and low in operating cost. The vertical rotary filter is suitable for solid-liquid separation and concentration.

Description

technical field [0001] The invention relates to a solid-liquid separation and concentration equipment, especially a rotary filter. Background technique [0002] At present, the widely used solid-liquid separation and solid concentration equipment mainly include: drum vacuum or pressure filter, multi-disc filter, etc., which are widely used in mining, smelting, papermaking and other industries. These devices are basically a horizontal rotary structure, mainly composed of a tank body, a machine cover, a horizontal drive shaft, a distribution valve, a stripping device, a water spray device for washing nets, a transmission device, and a discharge device. During the filtering process of this machine, about half of the filtering area is above the liquid level, so the effective filtering area is small, the filtering layer is difficult to access, the filtering efficiency is low, and a large amount of air enters the filtering layer, and a high-power vacuum is required. System and wa...
