Combined type dry method horizontal sorting machine

Abstract

The invention provides a combined type dry method horizontal sorting machine. The combined type dry method horizontal sorting machine comprises a sorting bed, an electromagnetic vibrator installed at the rear end of the sorting bed and used for making the sorting bed vibrate, and a plurality of air chambers arranged under the bed surface of the sorting bed and used for making air holes evenly formed in the airflow passing bed surface act on sort materials. The sorting bed and the electromagnetic vibrator are both installed on a machine frame through a hoisting device. A horizontal air channel is arranged under the bed surface. The horizontal air channel extends to the rear end of the bed surface from an opening in one end of a sorted material inlet of the bed surface in the longitudinal direction and is communicated with the multiple air chambers. Horizontal wind power to the sorted materials (coal to be sorted) is increased by forming the horizontal air channel under the bed surface of the sorting bed, and the sorted materials are made to rotate and roll forwards, so that no sorting materials are detained in the sorting bed. The sorting lower limit is eliminated, and the sorting efficiency and the sorting precision are improved.

Description

technical field [0001] The invention belongs to the technical field of compound dry coal preparation, and in particular relates to a compound dry horizontal separator. Background technique [0002] Such as figure 1 As shown, the existing composite dry-process horizontal separator is mainly composed of a sorting bed 1, an electromagnetic vibrator 2 installed on the sorting bed 1 rear end in order to make the sorting bed 1 vibrate, and a device arranged on the sorting bed 1 Below the bed surface 3 so that the air flows through the air holes evenly arranged on the bed surface 3 to act on multiple air chambers 4 for sorting materials. The sorting bed 1 and the electromagnetic vibrator 2 are all installed on the frame 6 through the hanging device 5 , the bed surface 3 is also provided with a plurality of transverse grid bars 15 to realize coal separation and sorting, and it is not difficult to see from this figure that the existing bed surface 3 is axially (longitudinal) from on...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to change the sorting process or state of the sorting material (raw coal to be sorted) by improving the existing compound dry horizontal sorting machine, so as to overcome the sorting accuracy caused by the existence of the lower limit of sorting low problem
