Abstract
The invention discloses a silo cluster storage and coal transfer method for a large-sized coal logistics base. The method comprises the following steps of: (a) feeding coal raw materials into a silo; (2) discharging and proportioning the coal raw materials; (c) directly conveying coal to a shipment relay belt conveyor through a silo bottom belt conveyor, or when the silo is required to be reversed, unloading coal to a storage yard by the silo bottom belt conveyor through a silo reversing belt conveyor. The method has the advantages of effectively meeting the requirements of high-altitude maintenance of silo equipment and overhauling of daily equipment, emergently treating high temperature or spontaneous combustion coal in the silo and ensuring accuracy and uniformity of silo mixed coal by combination of an activating feeder and a belt weigher. Mixed coal operation can be implemented in the same operation line, and can also be implemented between any two operation lines.
Description
Technical field
The present invention relates to harbour coal saving, transfer technique, relate in particular to silo group storage and transfer coal method for Large-scale Coal Logistic Base.
Background technology
The outdoor Coal Yard of tradition Coal Ports stockyard arrangement form, the coal that stockyard adopts stacker-reclaimer, reclaimer work pattern to carry out stockyard is marched into the arena and appears on the scene.Under this form, the dustproof key area of coal jetty is the airborne dust of controlling stockyard.What China's harbour open storage was generally carried out is the mode of watering dust suppression, and carries out dust suppression in conjunction with wind-proof dust-suppression net around stockyard.
Watering dust suppression is subject to the impact of the natural conditions such as temperature, strong wind, and use is subject to certain restrictions, and also exists the actual coverage rate of stockyard sprinkler system cannot reach 100% simultaneously, must repeat at regular intervals watering, and produces the disadvantages such as secondary pollution.
Anti-wind net dust suppression can suppress coal dust by large-area reduction wind speed, and the northern ports of growing for water shortage, ice period has practicality.But anti-wind net dust suppression also exists following problem to need to solve: one, because being subject to that strong wind weather easily blows down etc., assurance factor limits, anti-wind net establish net height and covering power is very restricted, for the larger open storage of area, the coverage of anti-wind net cannot reach 100%.Two, the existence such as the operation circuit of the setting of anti-wind net and stockyard stacker-reclaimer and vehicle delivery conduit conflicts, and cannot accomplish that stockyard surrounding all lays, and has windproof blind area.
Summary of the invention
The object of the invention is to overcome the defect of prior art, a kind of generation that greatly reduces coal dust is provided, avoided the storage of the silo group for Large-scale Coal Logistic Base and the transfer coal method of environmental pollution.
Silo group for Large-scale Coal Logistic Base storage of the present invention and transfer coal method, it comprises the following steps:
(a) coal feedstock warehouse entry: coal feedstock enters dump car by top, the storehouse belt conveyer being arranged in a strip-type conveyer gallery 3 of same row's silo Cang Ding, dump car is sent into each silo by dump car funnel through the inlet point that is positioned at belt conveyer both sides, every silo top by coal, described belt conveyer gallery line of centers and silo disalignment 0.9-1.1 rice;
(b) coal feedstock delivers from godown and prepares burden: coal is by opening the import of a corresponding activating feeder of arranging below the discharging opening at the bottom of every silo cylinder enters each discharging opening, then by activating feeder to belt conveyer feed at the bottom of storehouse, by being arranged at the bottom of described storehouse the belt conveyer locational pair of roller belt conveyer scale that deliver from godown, the flow of the raw material that delivers from godown is measured according to predetermined proportion scale discharging simultaneously, described two roller belt conveyer scales pass to controller by metering signal, controller compares setting signal and metering signal then to export the motor of control signal to described activating feeder, reach the effect of controlling flow,
(c) at the bottom of storehouse, belt conveyer is directly delivered to shipment relay belt conveyer or when needs silo is taken grain out of a granary to sun it, at the bottom of storehouse, belt conveyer unloads coal to stockyard by coal by the belt conveyer of taking grain out of a granary to sun it by coal.
The major advantage of the inventive method is:
1. belt conveyer gallery line of centers and silo disalignment 0.9-1.1 rice, the larger side in vestibule space, top, storehouse can be used as plant maintenance region, in this region, can carry out maintenance of equipment transport channel and the maintenance activity points such as dump car, belt feeder, also can set up standby redundancy storage area, actv. has solved the needs of silo equipment high-altitude maintenance and everyday devices maintenance simultaneously.
2. the method for taking grain out of a granary to sun it is high temperature or spontaneous combustion coal in emergency handling silo, due to uncertain factor, makes the interior coal period of storage of silo long, especially hot summer, silo tans by the sun for a long time under the sun, and coal temperature is easy to raise, and coal need to be poured out while reaching the situation of dangerous values; The 2nd, coal of the same race closes storehouse.When silo is changed coal, in silo, part clout is poured out.
3. silo coal blending can guarantee accuracy, the homogeneity of mixture coal by activating feeder and belt conveyer scale combination.
4. the operation of mixture coal both can realize in same lines, also can between two lines, realize arbitrarily.
5. the coal of sealing silo is stored up form, actv. solved the environmental protection of Large-scale Coal harbour, energy-conservation, account for Land less.
