Abstract

The invention relates to the technical field of sand screening devices, more specifically, a multi-stage sand screening device for buildings. The sand screening precision of each sand screening structure of the device is different, and the sand screening precision of the two sand screening structures in symmetrical positions is the same. The unused sand screening structure is placed in the placement frame with a fixed lock, and the two sand screening structures used are symmetrical two sand screening structures with the same precision, and are fixed by two fixing plates to form a complete screen. Use the drive mechanism to drive the linkage frame to reciprocate, and at the same time drive the connecting frame and the fixed plate to reciprocate, so that the two sand screening structures can play the role of screening sand in the reciprocating motion. When replacing the sand screening structure according to the demand, you only need to use the Push the sand screening structure back into the shelf, lock it with a fixed lock, and then slide out the required sand screening structure to play the role of sand screening. The screens of different precisions are integrated with the device body, and can be flexibly replaced with different precisions according to needs. The screen is easy to replace and flexible to use.

Description

technical field [0001] The invention relates to the technical field of sand screening devices, in particular to a building multi-stage sand screening device. Background technique [0002] For example, the building sand screening device whose publication number is CN108654971A includes a car body, a transmission assembly, a sand screen pan, and a sand storage tray. Device assembly, sheave driving device assembly includes support slats, gear set, left sheave toggle device, right sheave toggle device, middle sheave, left sheave toggle device, right sheave The toggle device includes a fixed shaft, a lever, a pin arranged at the end of the lever, and a convex locking arc. A central shaft is arranged in the center of the middle sheave, and the top of the central shaft passes through the transmission box and connects with the sand screen disc. The sand can be used in different occasions after being screened with different precision screens. Although the device can replace the scre...
