Molding sand buffering hopper for steel preparation

Abstract

The invention discloses a molding sand buffering hopper for steel preparation. The molding sand buffering hopper structurally comprises a motor, a dust cover and an anti-blocking hopper, the motor is mounted at the right end of the dust cover, the bottom of the motor is arranged at the top of the anti-blocking hopper, a rotating rod drives a connecting rod to rotate in a hopper body so as to stir molding sand, and the molding sand is prevented from caking in the hopper body; through hinging of a torsion shaft, the angle of a scraper blade can be adjusted and changed in the process that the scraper blade scrapes the inner wall of the hopper body, the effect that the scraper blade downwards scrapes the molding sand adhering to the inner wall of the hopper body is improved, and the molding sand is prevented from adhering to the inner wall of the hopper body; a lower swing mechanism guides and limits an extrusion rod through a fixing pipe sleeve in the up-down sliding process, and meanwhile, through elastic deformation of springs, the vertical extrusion force of the lower swing mechanism is improved, so that the effect that the lower swing mechanism pushes out the molding sand at the lower end opening of the hopper body is accelerated, and the molding sand is prevented from being blocked at the lower end opening of the hopper body.

Description

technical field [0001] The invention relates to the technical field of steel preparation, and more specifically relates to a molding sand buffer bucket for steel preparation. Background technique [0002] Molding sand is generally made by mixing molding materials such as raw sand for casting, molding sand binder and auxiliary additives in a certain proportion, and can be divided into clay sand, water glass sand, cement sand, resin sand, etc., and clay sand is also made of natural Silica sand, clay, additives and water are mixed. When preparing steel, the molding sand needs to be buffered and unloaded through a buffer bucket. However, since the manufactured sand mold can be directly poured with molten metal without drying, the buffered During the material process, the sand mold contains a certain amount of water, which will easily cause the sand mold to agglomerate inside the buffer bucket, and the buffer bucket has a structure with a wide top and a narrow bottom, which cause...

When preparing steel, the molding sand needs to be buffered and unloaded through a buffer bucket. However, since the manufactured sand mold can be directly poured with molten metal without drying, the buffered During the material process, the sand mold contains a certain amount of water, which will easily cause the sand mold to agglomerate inside the buffer bucket, and the buffer bucket has a structure with a wide top and a narrow bottom, which causes the sand mold to fall on the inner wall of the buffer bucket during the process of falling inside the buffer bucket. Adhesion occurs on the surface, and at the same time, blockage occurs during the discharge process, making it difficult for the molding sand to be discharged from the buffer hopper
