Abstract

The invention discloses a screening device for chemical experiments. The device comprises a base, a first-level screening tray, a second-level screening tray and a third-level screening tray, whereinthe bottom surface of the first-level screening tray is sealed, the bottom ends of the second-level screening tray and the third-level screening tray are open, screens are fixed to the inner walls ofthe second-level screening tray and the third-level screening tray in the circumferential directions respectively, the outer sides of the first-level screening tray, the second-level screening tray and the third-level screening tray are connected with discharging connectors in a sealed mode respectively, the lower ends of the discharging connectors are fixedly connected with discharging ports, theouter edges of the top cover lower end and the upper and lower ends of the first-level screening tray, the second-level screening tray and the third-level screening tray are fixedly connected with connecting trays respectively, locking mechanisms are arranged between each two of the adjacent connecting trays, a protection box is fixedly connected with the middle portion of the bottom surface of the first-level screening tray, a vibration motor is installed in the protection box, counter weights are arranged at the upper and lower ends of the vibration motor respectively, and multiple telescopic springs are fixedly connected between the first-level screening tray outer edge and the base outer edge. By means of the device, the problems are solved that the automation degree and the screeningefficiency of current screening devices for the chemical experiments are low.

Description

technical field [0001] The invention relates to the technical field of chemical experiment equipment, in particular to a screening device for chemical experiments. Background technique [0002] When conducting coal chemical experiments, it is usually necessary to screen the crushed and ground coal powder for coal quality analysis of different particle sizes, but most of the existing screening devices for chemical experiments have simple structures, low automation, and low efficiency.
