Problems solved by technology

However, the structure design of the current molding sand desilting hopper is unreasonable, and it is not convenient to clean up the mud in the molding sand. It is troublesome to clean the sludge during the cleaning process, which increases the labor intensity.
[0004]With the improvement of foundry technology level, higher requirements are put forward for the quality of molding sand. This kind of molding sand desliming structure can no longer meet the requirements of modern technology

Abstract

The invention relates to the technical field of molding sand processing, in particular to a waste molding sand classification desliming device, comprising an organic shell, a flushing aeration type desliming hopper and a drainage filter hopper, and the flushing aeration type desliming hopper and the drainage filter hopper are arranged in sequence Inside the casing, a water outlet pipe, a water inlet pipe and an aeration communication pipe are arranged in sequence on one side of the casing. One end of the aeration communication pipe is connected with the aeration working end at the bottom end of the flushing aeration type desliming bucket, and the other end of the aeration communication pipe is connected with the working end of the aeration device. Mud, aeration mixed desliming is more stable, and soil cleaning is easier.

Description

technical field [0001] The invention relates to the technical field of molding sand processing, in particular to a waste molding sand classification and desliming equipment. Background technique [0002] Molding sand is an important industrial raw material with special uses in foundry technology. Molding sand is mainly obtained by washing natural silica sand and removing soil impurities. [0003] At present, the process of removing impurities is to add water to the raw sand to make mortar, and then send it to the desliming hopper through the sand feeding pipe for desliming. However, the structural design of the current molding sand desliming bucket is unreasonable, and it is not convenient to clean up the mud in the molding sand. During the cleaning process, the cleaning of the sludge is troublesome, which increases the labor intensity. [0004] With the improvement of casting technology level, higher requirements are put forward for the quality of molding sand. This kind ...
