Sand treatment equipment and method in foundry industry

Abstract

The invention relates to the technical field of sand treatment, and discloses sand treatment equipment in foundry industry, which comprises a shell, a top cover is fixedly mounted at the top end of the shell, a feeding hole is formed in the top cover, a transverse plate is slidably connected in the top cover, electromagnets are fixedly mounted on the left side and the right side of the transverse plate in the top cover, and the electromagnets are fixedly mounted on the left side and the right side of the transverse plate in the top cover. According to the sand treatment equipment and method in the casting industry, on-off of the control switch is automatically controlled through the weight of remaining materials on the surface of the buffer plate, then opening and closing of the feeding opening are controlled, and the effect of automatically supplementing materials into the shell is achieved; and then the materials in the shell are screened out through the discharging opening with the gradually-reduced cross section area and are screened out again under the action of the stirring rod and the rotating rod, so that the impurities large in size and mass are gradually screened out, and the phenomenon that screening is not thorough due to the fact that the impurities are screened out once is avoided.

Description

technical field [0001] The invention relates to the technical field of sand treatment, in particular to a sand treatment device and method in the foundry industry. Background technique [0002] Sand treatment equipment is an indispensable supporting equipment for lost foam casting. Its operation is simple and economical. In the process of screening impurities, today's sand treatment equipment can screen the ferromagnetic foreign matter inside the impurities very well. After the reciprocating screening, the internal ferromagnetic substances can be completely removed, and the sand processing equipment also has the functions of cooling and dust removal. [0003] Sand treatment equipment has a good screening effect on ferromagnetic impurities, but when screening impurities with a small difference in volume, it cannot effectively screen impurities, and multiple screenings are required to screen out impurities. In the process, the material is directly screened to remove impuritie...

AI Technical Summary

Problems solved by technology

[0003] Sand treatment equipment has a good screening effect on ferromagnetic impurities, but when screening out impurities with similar volumes, it cannot effectively screen impurities, and multiple screenings are required to screen out impurities. Directly screening the materials to remove impurities during the process will reduce the screening rate of accumulated impurities at the discharge port, thereby reducing the screening efficiency

[0004] Aiming at the deficiencies of the prior art, the present invention provides a sand treatment equipment and method in the foundry industry, which has the advantages of step-by-step screening of impurities and automatic feeding, and solves the problems of inability to completely screen out impurities and untimely manual feeding. question
