Efficient recovery device for waste residues generated in production of polyaluminum chloride

Abstract

The invention relates to the technical field of recovery of waste residues generated in production of polyaluminum chloride, and particularly relates to an efficient recovery device for waste residues generated in production of polyaluminum chloride. The efficient recovery device for the waste residues generated in production of polyaluminum chloride comprises a supporting shell, a feeding pipeline, a filtering device, an infinitely variable speed device, a driving mechanism and a transmission mechanism, wherein the filtering device comprises a first port, a second port, a plurality of elastic plates and a plurality of filter screen assemblies; one end of the infinitely variable speed device is connected with the second port, and the infinitely variable speed device is configured to increase the rotating speed of the second port when the resistance of a load at one end is reduced, so that the second port moves downwards through change of the structure of the infinitely variable speed device; the plurality of elastic plates are configured to be arched inwards when the second port moves downwards; each filter screen assembly comprises an elastic strip and two groups of connecting rods, and the filter screen assemblies are configured to be arched outwards when the second port moves downwards; and each group of connecting rods comprises a plurality of connecting rods, the rotating speed of the second port is increased, the included angle between the two groups of connecting rods of each filter assembly is reduced when the second port moves downwards, and the particle size allowed to pass through is reduced.

Description

technical field [0001] The invention relates to the technical field of polyaluminum chloride waste slag recovery, in particular to a high-efficiency polyaluminum chloride production waste slag recovery device. Background technique [0002] Polyaluminum chloride is a water purification material, inorganic polymer coagulant, also referred to as polyaluminum, English abbreviation is PAC, the molecular weight produced due to the bridging effect of hydroxide ions and the polymerization of polyvalent anions Larger, higher charge inorganic polymer water treatment agent. It can be divided into solid and liquid in form. The solid is divided into brown, beige, golden yellow and white according to the color, and the liquid can be colorless and transparent, slightly yellow, light yellow to yellowish brown, and polyaluminum chloride of different colors has different advantages in application and production technology. big difference. [0003] The production of polyaluminum chloride in...
