Abstract

A fast spiral filter, its structure is that the filter is equipped with a main body, the front end is equipped with a feeding cylinder and the rear end is equipped with a rear end cover, the middle of the main body is provided with a filter screen skeleton and a filter screen or filter cloth is installed on it, and the upper end of the main body is provided with a pressure filter. Table, the lower end is equipped with a slope type liquid collection tank, installed with a liquid outlet hole, connected by a flange to the discharge pipe, the screw shaft is provided with a spiral piece and a material guide piece, and the feeding cylinder is installed to install the drive shaft sleeve to connect to the motor. The upper end of the cover is provided with a safety valve, the lower end is provided with a discharge hole and a control valve is installed, the rear end cover is provided with a bearing box to install bearings, and the front outrigger and the rear outrigger are installed under the liquid collection tank and the feeding cylinder. A fast spiral filter achieves the effects of continuous filtering and cake unloading, saves energy and reduces costs, has a compact structure, occupies a small area, is convenient to operate, and is safe to use to improve filtration efficiency.

Description

technical field [0001] The present invention relates to a filter. More specifically, it refers to a fast screw filter. Background technique [0002] The filter is the filtration equipment in the solid-liquid separation machinery industry. Due to the economic development, the filter is widely used in various solid-liquid separation machinery industries, and the scope of the filter is gradually expanded. The solid particles contained in the current solid-liquid separation filter There are many kinds of materials, and some materials are suitable for injecting materials into the filter chamber without the feed pump. The pressure of the feed pump will easily cause solid particles to block the filter cloth. Only when the materials are suitable for uninterrupted continuous filtration and unloading cakes can they meet the requirements of the material design process for filtration. [0003] The currently used plate-frame and box-type filter presses have deficiencies in the filtratio...
