Problems solved by technology

[0003] However, when the existing coal preparation machine selects coal, because the raw coal directly slides from the vibrating screen, the residence time is short, and it cannot be fully selected and screened. In this way, the same batch of raw coal may have to go through multiple screenings before it can be completely distinguished, resulting in The coal preparation process has high cost, low efficiency, and increases the labor burden of workers

Embodiment 1

[0030] As shown in the accompanying drawings, a coal separator with high coal stagnation performance of this patent is used to screen clean coal from raw coal. Road 5, vibrating screen 3, vibrating motor 1, mounting frame, retention device 2 and coal discharge device 8.

[0031] The base 7 is provided with a bolt through hole, and the fastening bolt passes through the bolt through hole to fasten the base 7 on the ground; the height adjustment device 6 is two hydraulic cylinders, and the two hydraulic cylinders are vertically arranged at one end of the base 7; One end of the slideway 5 is connected to the piston rods of two hydraulic cylinders, and the other end is hinged with the base 7. The hydraulic cylinder can adjust the slope of the clean coal slideway 5 through the expansion and contraction of the piston rods; the vibrating screen 3 is arranged above the clean coal slideway 5, and It is connected with the clean coal slideway 5 through the spring 4; the vibration motor 1 ...

Abstract

The invention introduces a coal picker with high coal retention performance, and aims at screening cleaned coal from raw coal. The coal picker with the high coal retention performance is characterized by comprising a base, a fastening bolt, an adjusting height device, a cleaned coal chute, a vibrating screen, vibrating motors, a mounting rack, a retention device and a coal discharging device. The coal picker is high in coal picking efficiency, applies to the raw coal with different ingredients, and is wide in applicable scope, high in pertinence, and good in coal picking effect.

Description

technical field [0001] The invention relates to the technical field of coal mine equipment, in particular to a coal separator with high coal stagnation performance. Background technique [0002] Coal preparation is also called coal washing, which is the process of sorting clean coal that meets the quality requirements of users from raw coal. The coal used for coking has certain requirements on ash and sulfur content, and clean coal that has been washed must be used. The lithofacies composition of coal and the quantity, type, nature and distribution state of minerals in coal are all factors that affect the selectivity of coal. According to the degree of difficulty of raw coal selectability, the commonly used processes in coal preparation plants include jigging, dense medium cyclone, dense medium shallow tank, moving screen jigging, flotation, etc. Other coal preparation methods include winnowing, spiral separation and so on. [0003] However, when the existing coal prepara...
