Description

Coal spout

Technical field

The transport system technical field such as harbour, electric power, colliery, chemical industry is the utility model is related to, more particularly to it is a kind of scattered The coal breakage pipe device used in material course of conveying.

Background technology

Coal transmission during exploitation, processing and use is essential step, so that for transmitting the coal of coal Charcoal transmitting device also becomes indispensable equipment in exploitation, processing and use.Existing frequently-used coal transmitting device includes branch Support, splicing belt and coal spout.Supporting rack is fixed and stands on ground, for the whole coal transmitting device of support bearing；This falls Coal pipe is fixedly installed on the supporting rack and guides coal to drop on the splicing belt positioned at the top of the splicing belt；Should Splicing belt is installed on the supporting rack to transmit coal.When whole coal transmitting device is started to work, coal is from the coal breakage The opening of pipe upper end enters in the coal spout, and on the splicing belt that the coal spout drops below the coal spout, this connects Material belt continuous back and forth or left and right side under the drive of other power set is rotated up so as to which the coal that will fall off thereon passes It is defeated to arrive pre-set destination, to realize the transmission to coal.

However, at present in the transmitting procedure of coal, dust concentration is high, and chute blockage product coal phenomenon often occurs, equipment attrition Seriously, operating environment is severe.It is in particular in：Firstth, due to the impact of coal stream, head funnel abrasion and chute blockage and powder are caused Dirt produces.Specifically, structure easy chute blockage in the exceeded coal stream of conveying water content in corner dead angle at head funnel；Conveying Easily cause the generation of dust during dry coal stream, and increase into the induced air air quantity in coal spout.Secondth, longer coal breakage The included buffering air lock device of pipe is normally opened state in the case where substantial amounts of coal stream impacts always, so behind coal stream Splicing belt is directly impacted, coal dropping point can not be biased to outside between two parties, coal dropping point can not cause splicing belt deviation between two parties, grind Damage is serious, output drop, and unit consumption rises, and so easily smashes deflector chute side plate and anti-overflow skirtboard, causes a large amount of dust from side Overflowed at plate.3rd, due to coal spout vertical design in defeated coal movement system, coal stream is caused directly to impact splicing belt, equally Preventing belt from scratches and impact wear are caused, reduces belt life.4th, can be produced when coal stream impact flapper lock turnover panel a large amount of Induced air, makes the wind speed of deflector chute greatly increase, and easily produces dust；Coal fluid capacitance easily impacts the top of flapper lock turnover panel Dead angle, easily produce product coal, in the course of time easily produce chute blockage.

Accordingly, it is desirable to provide a kind of improved coal breakage pipe device, which can reduce impact, mill Damage, the risk blocked, can also maximum magnitude reductions induced air air quantity and because sideslip causes the airborne dust of bulk cargo generation, and can carry Rise the specified conveying capacity of belt feeder and extend the service life of belt feeder.
