Problems solved by technology

[0004] (1) The traditional casting sand pretreatment system needs to screen the raw sand when processing the molding sand, and the unqualified raw sand after screening needs to be cleaned and collected manually, which increases the processing cost
[0005] (2) The traditional foundry sand pretreatment system usually mixes a small amount of raw sand and binder when processing the molding sand. When mixing a large amount of raw sand and binder, due to the Due to the physical properties of the binder, it takes a long time to stir it, and the working efficiency of the equipment is low

Abstract

The invention relates to a casting sand pretreatment system, which includes a workbench, a collection device, a screening device and a stirring device. The collection device is fixedly installed on the lower end surface of the workbench, and the sieving device is fixedly installed on the left upper end surface of the workbench. A stirring device is fixedly installed at the right end of the screening device. The present invention screens the raw sand through the screening device, and uses rubber strips to make the rectangular leaking plate closely contact with the shell to prevent the raw sand particles that do not meet the screening size of the rectangular leaking plate from entering. In the lower area, the spring is used to further limit the movement track of the rectangular bushing plate, and at the same time prevent the rectangular bushing plate from violently colliding with the shell when it moves up and down, resulting in damage, and collect the raw sand that does not meet the requirements through the collection device, so as to To prevent the raw sand left after screening from affecting the efficiency of the subsequent raw sand screening, the raw sand and the adhesive are completely stirred by the stirring device.

Description

technical field [0001] The invention relates to the field of casting treatment, in particular to a casting sand pretreatment system and treatment method. Background technique [0002] Molding sand is generally mixed with molding materials such as raw sand for casting, molding sand binder and auxiliary additives in a certain proportion. It is mainly used as a material for making sand molds. The main function of raw sand is to provide necessary high temperature resistance for molding sand. performance and thermophysical properties, and at the same time provide many pores for the sand mold to ensure that the sand mold has a certain degree of air permeability, and the binder plays the role of bonding the sand particles, so that the molding sand has the necessary strength and toughness. [0003] In the process of processing molding sand, due to the structural limitations of the original sand, the following problems exist in the actual operation process: [0004] (1) The traditio...
