Abstract
A lump coal sieving device comprises two scraper conveyors, an on-sieve belt conveyor and an under-sieve belt conveyor. The on-sieve belt conveyor is provided with a bifurcate hopper, and two banana screens are arranged under each scraper conveyor. The under-sieve belt conveyor comprises a pulverized coal belt conveyor body and a lump coal belt conveyor body. The two scraper conveyors are located below the on-sieve belt conveyor, and the pulverized coal belt conveyor body and the lump coal belt conveyor body are placed below all the banana screens. According to the lump coal sieving device, coal flow at a feeding opening is evenly partitioned, and meanwhile the material flow shunt amount on the two sides is adjusted, so that destructive impact on downstream equipment is avoided, and the service life of the equipment is overall guaranteed. According to the lump coal sieving device, the overall steel structure design is adopted so that the influence of high-strength vibration on the equipment can be reduced, the sieving capacity of the device is high, the sieving efficiency is high, the equipment fault rate is low, and material distributing errors are small.
Description
Technical field
The present invention relates to screening field, be specifically related to a kind of device for lump coal screening.
Background technology
Along with the development of domestic Coal Ports, enriching of coal source, improves Coal Quality and has become the key improving Business Economic Benefit, and lump coal screening enters into Coal Ports field from the field such as colliery, coal preparation plant.In prior art, carry out coal and enter screening tower by tippler or ship unloaders, by screening operation, lump coal and fine coal are separated, lump coal belt feeder under sieving front chute to be transferred to sieve enters stockyard, fine coal belt feeder under sieving lower chute to be transferred to sieve enters stockyard, thus by materials different for granularity separately, but in actual moving process, because equipment is walked, coal is many, load is many, wearing and tearing are large, the scrapper conveyor of both sides and the easy stream inequality of vibratory sieve, vibration equipment is serious, and then causes the fault rate of equipment many, there is the problems such as point doses error is large.
Summary of the invention
The invention provides a kind of lump coal screening plant, its stream is even, and vibration equipment is little, and equipment failure rate is low, and sub-material error is little.
The present invention is for achieving the above object by the following technical solutions:
Lump coal screening plant comprises two scrapper conveyors, belt feeder on sieve, the lower belt feeder of sieve, on described sieve on belt feeder with bifurcated funnel, two platform banana screens are respectively equipped with below described each scrapper conveyor, under described sieve, belt feeder is divided into fine coal belt feeder and lump coal belt feeder, and described two scrapper conveyors are positioned at below the upper belt feeder of sieve, and described fine coal belt feeder and lump coal belt feeder are positioned at below each banana screen.
On described sieve on belt feeder with three-way chute, being provided with in described chute can the flow distribution plate of pivotable.
Described banana screen side is connected with the front chute of sieve.
Described lump coal screening plant adopts integrated steel-structure.
Described banana screen is detachable mono-layer banana screen.
Described banana screen top is provided with vibration isolation frame.
The beneficial effect that the present invention realizes is:
Even partition is carried out to feeding mouth coal stream, regulate the stream shunt volume of these both sides simultaneously, thus avoid impacting damaging property of upstream device, the support equipment life-span on the whole, screening plant adopts integrated steel-structure design to decrease the impact of high-intensity oscillation on equipment, and device sieving capacity is strong, and screening efficiency is high, equipment failure rate is low, and sub-material error is little.
Accompanying drawing explanation
Figure 1 shows that lump coal screening plant front view.
Figure 2 shows that lump coal screening plant left view.
Wherein, belt feeder on 1-sieve, 2-scrapper conveyor, 3-banana screen, the lower belt feeder of 4-sieve, 41-fine coal belt feeder, 42-lump coal belt feeder, chute before 5-sieve, 6-bifurcated funnel.
Detailed description of the invention
Lump coal screening plant comprises two scrapper conveyors 2, belt feeder 1 on sieve, the lower belt feeder 4 of sieve, on described sieve on belt feeder 2 with bifurcated funnel 6, two platform banana screens 3 are respectively equipped with below described each scrapper conveyor 2, under described sieve, belt feeder 4 is divided into fine coal belt feeder 41 and lump coal belt feeder 42, and described two scrapper conveyors 2 are positioned at below the upper belt feeder 1 of sieve, and described fine coal belt feeder 41 and lump coal belt feeder 42 are positioned at below each banana screen 3.On described sieve on belt feeder 1 with three-way chute, being provided with in described chute can the flow distribution plate of pivotable.Described banana screen 3 side is connected with the front chute 5 of sieve.Described lump coal screening plant adopts integrated steel-structure.Described banana screen 3 is detachable mono-layer banana screen.Described banana screen 3 top is provided with vibration isolation frame.
