Dense medium coal sorting plant automatic medium adding system

Abstract

The invention provides a dense medium coal sorting plant automatic medium adding system. The dense medium coal sorting plant automatic medium adding system comprises a travelling crane, a grab bucket,a material storage bin, a conveyor, pump pools, conveying pumps, liquid level detection devices, a clean water pipe, an air pipe and a control device, wherein the grab bucket is connected to the travelling crane and located above the material storage bin, the conveyor is arranged below a material outlet of the material storage bin, an outlet of the conveyor is provided with the pump pools, the upper portions of the pump pools are provided with the conveying pumps, the liquid level detection devices, the clean water pipe and the air pipe, the top of the material storage bin is provided with amaterial level sensor, the periphery of the outer wall of the material storage bin is provided with a heat preservation device, and the clean water pipe is provided with a flow gauge and electric valves. By means of the dense medium coal sorting plant automatic medium adding system, the technical problems in the prior art that large human and material resources are consumed, the manual operation stability is poor, the production requirements cannot be met in time and efficient sorting is not facilitated due to manual medium adding is adopted are solved.

Description

technical field [0001] The invention relates to the field of coal, in particular to an automatic loading system for a dense medium coal preparation plant. Background technique [0002] Dense medium separation technology has the advantages of high-precision separation, easy operation, and easy implementation of automation, so it is favored by various countries. In major coal-producing countries, dense medium coal preparation has gradually become the main coal preparation method. The working principle of dense medium coal preparation is that during separation, the suspension with appropriate density and the raw coal to be sorted are mixed into the separator, and the coal with a lower density than the suspension floats, while the gangue with a higher density sinks. , and then use the separation technology to separate and discharge the coal and gangue, pass through the sieve plate, and carry out the deintermediation treatment of the suspension to realize the separation of raw co...
