Description

Technical Field

[0001] The invention belongs to the technical field of classifiers, in particular to a classifier for plate sand production. Background Art

[0002] Plate sand classifier is a kind of equipment specially used for grading and screening plate sand. The working principle of plate sand classifier mainly depends on the vibration of screen body and the screening effect of screen. Square swing screen is one of the plate sand classifiers. After the screen machine is started, the screen box reciprocates back and forth under the action of inertia force, and the screen box drives the screen surface to shake periodically, so that the material on the screen surface makes a planar rotary motion with the screen box. During this period, the material smaller than the screen hole diameter falls to the lower layer through the screen hole and becomes the undersize material. The material larger than the screen hole diameter is discharged from the discharge port after continuous tumbling and jumping motion, completing the screening work.

[0003] In the existing square swing screen, the screening net is connected to the classifier body by multiple bolts, nuts or other fasteners. In actual use, when the screening net needs to be replaced, the workload is large, and it is inconvenient to replace the screening net, which increases the difficulty of disassembly. The existing square swing screen mainly relies on the vibration of the screen body to screen the plate sand. When the plate sand enters the square swing screen, the plate sand is in a piled state on the screening net, and its distribution is uneven, resulting in poor screening efficiency.
