Upper side and lower side executing mechanism for intelligent dry separation machine

Abstract

The invention provides an upper side and lower side executing mechanism for an intelligent dry separation machine. According to the upper side and lower side executing mechanism, selected materials are identified into three materials A, B and C by using the identifying system of an intelligent dry separation machine; the upper side and lower side executing mechanism uses a corresponding high-frequency electromagnetic valve to control an air spraying nozzle to spray any two materials of the three materials A, B and C in a synchronous or delayed manner; and the material A sprayed by an upper side executing mechanism from top to bottom enters a channel 1, the material C sprayed by a lower side executing mechanism from bottom to top enters a channel 3, and the un-sprayed material B enters a channel 2, such that the mixed raw materials are finally separated into the three products A, B and C through sorting. According to the present invention, with the upper side and lower side executing mechanism, the three products A, B and C can be sorted at one time; and the upper side and lower side executing mechanism is suitable for the process for sorting three products, and has characteristicsof effectively-simplified process, investment saving, reduced production cost and improved production efficiency.

Description

Technical field [0001] The invention belongs to the technical field of mineral dry sorting, and specifically relates to an upper and lower side type executive mechanism of an intelligent dry sorting machine for sorting minerals. Background technique [0002] Coal sorting is mainly divided into two directions: water washing and dry sorting. The water washing basically adopts jigging, heavy-medium, flotation and other processes. Its advantages are that after years of development, the technology has matured and the sorting accuracy meets the requirements of production and use; the disadvantages are large construction investment, high production costs, and serious water consumption and waste. . Dry separation is a coal preparation method that has existed and slowly developed in the past two decades. It has the advantages of no water, simple process, low investment and low production cost. The main representative process is a composite dry separation based on vibration and air separa...

AI Technical Summary

Problems solved by technology

[0008] The technical problem to be solved by the present invention is to provide an upper and lower two-side actuator for an intelligent dry sorter in view of the above-mentioned deficiencies in the current automatic sorting technologies based on gamma rays or X-rays. Material A, material B and material C can be sorted separately by using the actuator, which makes up for the deficiency that the existing intelligent dry separator cannot sort three products on one device
