Suction and discharge type material separating and sorting device

Abstract

The invention belongs to the field of separation devices, and relates to a suction and discharge type material separating and sorting device. The device comprises a base, the top side of the base is fixedly connected with the bottom sides of two supporting plates distributed front and back, circular through grooves are formed in the upper portions of the supporting plates, first annular T-shaped grooves are formed in the inner circumferences of the circular through grooves, multiple first arc-shaped T-shaped sliding blocks are installed in the first annular T-shaped grooves in a sliding fit mode, elastic pieces are fixedly installed on the adjacent sides of the first arc-shaped T-shaped sliding blocks correspondingly, gears are fixedly installed at the outer ends of rotating shafts of motors correspondingly, and the gears can be engaged and matched with corresponding first arc-shaped racks correspondingly. The device is simple in structure and clever in conception, a semi-open drum screen overcomes the defect that feeding can only be conducted from one end, different screening requirements are met, the applicability is improved, meanwhile, the gaps between screen rods are continuously changed, solid particles clamped between the screen rods can be removed, and screening hindrance is reduced.

Description

technical field [0001] The invention belongs to the field of separation devices, in particular to a suction-discharge type material separation and sorting device. Background technique [0002] Before the limestone is put into use, it is necessary to use a drum screen to screen the limestone. Due to the drum type setting of the existing drum screen, it can only be fed from the end, and the gap between the screen rods of the drum screen is fixed and cannot be adjusted. , cannot meet different screening requirements, and at the same time, it is time-consuming and labor-intensive to clean the solid particles stuck between the sieve rods, which cannot meet the actual needs, so we invented a suction-discharge material separation and sorting device. Contents of the invention [0003] The invention provides a suction-discharging material separation and sorting device to solve the defects in the prior art. [0004] The present invention is achieved through the following technical ...
