Problems solved by technology

In the traditional reactor for extracting tin sludge, the stirring device in the reactor is an anchor stirring device; due to the high viscosity of the tin sludge, it is difficult to fully stir with the anchor stirring device, and part of the wastewater cannot be fully reacted, and it is easy to generate finer Particles; in the subsequent filter press process of separating tin sludge from wastewater, because the filter press particles are too fine, the filter cloth is prone to clogging and the filter press efficiency is reduced, and the moisture content of the tin sludge is high, resulting in low prices

Abstract

The invention relates to a stirring device. The stirring device comprises a main shaft and at least two stirring paddles. The stirring paddle comprises a cylindrical part provided with a central through hole and three blades. The three blades are uniformly fixed to the outer circumferential surface of the cylindrical part. The stirring paddles respectively pass through the central through holes ofthe cylindrical parts and are fixed to the main shaft. The two adjacent stirring paddles are arranged on the main shaft at a certain interval. The overlooking projections (vertical projections) of the three blades of the stirring paddle along the main shaft central axis are not coincident. The stirring device can fully stir de-tinning waste water materials in a reactor, improves product tin content and production efficiency and has the advantages of simple structure, high production efficiency and good quality.

Description

【Technical field】 [0001] The invention relates to a reactor, in particular to a stirring device in the reactor, in particular to a stirring device for the reactor in the treatment of tin stripping wastewater. 【Background technique】 [0002] Tin stripping wastewater is a kind of acid wastewater generated during the production process of printed circuit boards. The tin in it has important economic and environmental benefits. In wastewater treatment, it is usually necessary to extract tin sludge from the tin stripping wastewater first, and then do subsequent harmless processing. In the traditional reactor for extracting tin sludge, the stirring device in the reactor is an anchor stirring device; due to the high viscosity of the tin sludge, it is difficult to fully stir with the anchor stirring device, and part of the wastewater cannot be fully reacted, and it is easy to generate finer Particles; in the subsequent filter press process of separating tin sludge from wastewater, b...
