Dynamic continuous sucking filter with cage filtering barrel

Abstract

The dynamic continuous sucking filter with cage filtering barrel as one mechanical equipment includes a cage filtering barrel, a material guiding spiral belt device, a gas crossing disc, a vibrator, a left joint, a right joint and an elastic bearing part. Technologically, the present invention features that the rotating cage filtering barrel makes the flexible filtering medium in periodical alternating operation state of filtering and washing. The material guiding spiral belt device rotating synchronously with the cage filtering barrel force the slurry forward spirally, and the filter cake material moves along one cylindrical circular helix in constant changing state for solid-liquid separation. The filter-aiding vibrator further raises the separating efficiency. The filtering operation is especially suitable for separating liquid material with low viscosity and solid material with poor moisture absorption. The filter medium may be back washed and may be replaced easily.

Description

Technical field: [0001] The invention belongs to a solid-liquid separation equipment. It belongs to the technical field of mechanical equipment. Background technique: [0002] Filtration equipment has a wide range of applications in the chemical, pharmaceutical, textile, metallurgical, paper, food and other fields, and plays an important role. Therefore, filtering equipment has been developed by leaps and bounds to meet the needs of applications. However, due to the diversity of solid and liquid materials, the complexity of the slurry state, the particularity of the workplace, and the difference in separation requirements, the existing filtration equipment cannot meet the needs of various operating conditions and needs to be further developed. As one of the continuous filtering equipment, the rotating drum filter, such as the filter introduced in Patent No. 01279974, continuously completes a series of operations of filtering, pressing and drying, and back blowing and unloading th...
