Rapid separation device for sand washing water of casting old sand

Abstract

The invention discloses a rapid separation device for sand washing water of casting old sand. The rapid separation device comprises a shell body, wherein a bracket is arranged at the bottom of the shell body; a pressing block is arranged in the shell body; a first spring is arranged at the bottom of the pressing block; a connection device is arranged at the inner side of the pressing block; a bottom frame is arranged at the inner side of the connection device; a first filtering plate is arranged at the inner side of the bottom frame; a second filtering plate is arranged at the top of the firstfiltering plate; a rotary frame is arranged at the top of the second filtering plate; a motor is arranged at the top of the rotary frame; a pull plate is arranged at the top of the motor; a pull handle is arranged at the top of the pull plate; and a supporting rod is arranged on the top surface of the shell body. According to the rapid separation device, the connection device is arranged and thepulling plate is pulled so that the clamping plate has an extrusion effect on a second spring; after the bottom plate and a clamping frame are correspondingly placed through the bottom frame, the clamping plate is loosened; and the elastic force of the second spring is rebounded, and a movable block drives the clamping plate to fix the bottom frame on the connection frame, so that the effect of fastening the first filtering plate is realized.

Description

technical field [0001] The invention relates to the field of sand-water separation equipment, in particular to a sand-water rapid separation device for cleaning old foundry sand. Background technique [0002] It is a granular refractory material used to prepare molding sand and core sand in foundry production. The shape of foundry sand is generally divided into three types. ①Round sand: The particles are spherical or close to spherical, with smooth surface and no prominent edges and corners. ② Polygonal sand: The particles are polygonal, and most of them are obtuse angles. ③Sharp sand: The particles are pointed and have many sharp angles. The particle shape of foundry sand is generally expressed by the angular coefficient (the ratio of the actual specific surface area of ​​sand grains / theoretical specific surface area of ​​spherical sand grains). [0003] After cleaning the old sand, it is necessary to quickly separate the sand and water. Usually, it is filtered by a sie...

Problems solved by technology

[0003] After cleaning the old sand, it is necessary to quickly separate the sand and water. Usually, it is filtered by a screen, which cannot completely remove the water on the surface of the casting sand.
