Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides an environment-friendly foundry raw sand screening device based on the parts casting process to solve the existing one. Although the existing device can realize the vibration screening of sand and gravel, it cannot be used through structural improvement. Realize high-frequency auxiliary vibration screening at the same time of vibration screening; moreover, the existing device is easy to block the screen hole during the screening process, and cannot realize automatic plugging of the screen hole while screening; finally, the existing device It is easy to generate dust during the screening process, and it is impossible to automatically realize the purification of dust while screening through structural improvement

Abstract

The invention provides an environment-friendly casting crude sand screening device based on a part casting process, relates to the technical field of casting auxiliary equipment, and solves the problem that high-frequency auxiliary vibration screening cannot be realized while vibration screening is performed through structural improvement. And automatic blockage clearing of the sieve pores cannot be realized while screening is carried out. The environment-friendly casting crude sand screening device based on the part casting technology comprises a box body. The box body is of a rectangular box-shaped structure. Through the arrangement of the frame, the auxiliary rods are welded to the frame in the rectangular array shape, the auxiliary rods welded in the rectangular array shape are aligned to the screen holes formed in the rectangular array shape, and when the screening frame moves downwards, the auxiliary rods penetrate through the screen holes, and therefore sand clamped in the screen holes can be cleaned.

Description

technical field [0001] The invention belongs to the technical field of casting auxiliary equipment, and more specifically relates to an environment-friendly casting raw sand screening device based on a parts casting process. Background technique [0002] Raw sand is the most basic material for molding in foundry production, and the most widely used is quartz sand, commonly known as silica sand. In sand casting, raw sand is the aggregate and main component in the mixture, and the foundry sand used for the first time is called raw sand; in casting, there are certain performance index requirements for raw sand, so the raw sand needs to be screened. [0003] For example, the application number: CN201811613153.8, the invention provides a casting raw sand screening device, which solves the technical problems of low screening efficiency and insufficient screening effect in the existing screening technology. The foundry raw sand screening device includes a sand breaking device and ...
