Shaking bucket for pretreatment of casting raw materials and sand-shaking treatment process

Abstract

The invention relates to a shakeout hopper for pretreatment of casting raw materials and a shakeout treatment process, including a bottom plate, a vibrating device, a screening device, a dust collection device and a crushing device. A vibrating device is installed on the top of the bottom plate, and a screening device, a dust suction device is installed on the screening device, and a crushing device is installed at the lower end of the screening device. The present invention can solve the following problems that exist when the existing molding sand castings are separated. It is easy to block. The current method is to regularly manually push the push plate set in the discharge port, and use the push plate to push the sand blocked in the discharge port to achieve sand shakeout. The manual labor intensity is high and the sand shakeout efficiency is low; 1. When the traditional machine separates the sand castings, it cannot collect the impurities and dust generated when the sand and castings are separated, and a large amount of dust is discharged into the air, which affects the health of the staff and improves the separation efficiency of the sand castings.

Description

technical field [0001] The invention relates to the technical field of sand casting, in particular to a shakeout hopper for pretreatment of casting raw materials and a shakeout treatment process. Background technique [0002] Casting is the process of pouring smelted metal liquid into the mold, cooling and solidifying to obtain parts with the required shape and performance. Casting is a commonly used manufacturing method with low manufacturing cost and high process flexibility. It can obtain complex shapes and For large-scale castings, sand casting is to use clay-bonded sand as the molding material to produce castings. Molding sand is indispensable during casting. Before casting, the molding sand is made into a model. After casting, the mold is broken to make the mold and the sand box Separation, the casting is separated from the molding sand. [0003] However, the following difficult problems exist in the separation of the current molding sand castings. One, when the tradi...

Problems solved by technology

[0003] However, the following difficult problems exist in the separation of the current molding sand castings. One, when the traditional molding sand castings are separated, the discharge opening of the shakeout hopper is easy to block. The plate pushes the sand blocked in the discharge port to achieve sand shakeout, which has high labor intensity and low sand shakeout efficiency; 2. When the traditional machine separates the sand castings, it cannot separate the impurities and dust generated when the sand and castings are separated. Collect, and produce a large amount of dust to be discharged into the air, which will affect the body of the staff, and it is not easy to block the outlet, which improves the efficiency of the separation of molding sand castings
