Description

High-efficient ball sand separator
Technical Field
The utility model relates to a shot blasting machine ball sand separator field especially relates to a high-efficient ball sand separator.
Background
The separator is one of key parts of shot blasting cleaning equipment, and in the running process of the shot blasting equipment, the shot blasting machine throws shots on a workpiece at a certain speed, and the shot falling to the bottom of the chamber body comprises oxide skin, sand grains, broken shots and the like thrown from the workpiece besides steel shots, so that the mixture at the bottom of the chamber body needs to be further separated for recycling the steel shots. The quality of the separation is not only directly related to the productivity of the equipment and the life of the wearing parts (especially the blades in the impeller head), but also affects the surrounding dust concentration and the consumption of the shot and the surface quality of the workpiece. The related data show that when the sand content of shot materials reaches 2% in the shot blasting process, the abrasion condition of blades of the shot blasting machine is increased by 5-10 times compared with that of pure steel shots without sand, and the abrasion quantity of other vulnerable parts is also increased.
The prior pill sand separating device which is commonly used has two types of air separation separators and magnetic separation separators: the winnowing separator is mainly used for the shot-sand mixture with low impurity density and low content, and is widely applied to actual production due to simple structure and low manufacturing cost; the magnetic separator is mainly suitable for occasions with high impurity density in the shot-sand mixture, the separation effect of the magnetic separator is superior to that of a winnowing separator, the separation effect can reach 99.5%, and particularly, when the impurity content in the shot-sand circulating system is more than 10%, the advantages of the magnetic separator are more obvious. Both of the above-mentioned separation methods are not good in view of the separation of the crushed pellets.
According to the detection standard of the shot blasting machine separator: after the projectile is separated, the waste content of the qualified projectile is less than or equal to 1 percent, and the waste content of the qualified projectile is less than or equal to 1 percent. From the viewpoint of improving the service life of parts such as impeller head blades and the like, the amount of waste in the steel shot should be as small as possible, but the separation requirement for the separator is higher, which results in increased separation time and increased production cost, so that efficient shot-sand separation is very important.
