Problems solved by technology

For the coal in the open storage yard, there is no silo for mixed coal, and the stacker-reclaimer is used to directly transport the coal to the belt conveyor for mixed coal. The precision of mixed coal is low, and it is difficult to control the conveying capacity of the belt conveyor.

Embodiment Construction

[0044] The present invention will be further described in detail below with reference to the accompanying drawings, so that those skilled in the art can implement it with reference to the text of the description.

[0045] It should be understood that terms such as "having", "including" and "including" used herein do not equate the presence or addition of one or more other elements or combinations thereof.

[0046] Such as figure 1 As shown, the present invention provides a method for blending coal based on a buffer bin of a transfer station, which is characterized in that it includes the following steps:

[0047] Step 1: Conveying various coals into the buffer bins of the first transfer stations via the first belt conveyors;

[0048] Step 2: The multiple first transfer station buffer bins respectively quantify multiple types of coal and evenly spread them on multiple second belt conveyors;

[0049] Step 3. Various coals on multiple second belt conveyors are evenly spread layer by layer ...

Abstract

The invention discloses a method for mixing coals based on transfer station buffer bins. The method is characterized by comprising the following steps: (1) multiple coals are respectively conveyed to multiple first transfer station buffer bins by multiple first belt conveyors; (2) after the multiple first transfer station buffer bins respectively quantify the multiple coals, the multiple coals are uniformly spread on multiple second belt conveyors; (3) the multiple coals on the multiple second belt conveyors are uniformly spread on a third belt conveyor layer by layer; and (4) the multiple coals uniformly spread on the third belt conveyor layer by layer are mixed by at least two second transfer station buffer bins until the multiple coals are quantitatively mixed uniformly. The method can mix the coals with different types in different yards outdoors, adopts variable-frequency control for an activation feeder to mix the coals by any ratio, is high in mixing precision and mixing degree, and can precisely control the conveying capacity of the belt conveyors.

Description

Technical field [0001] The present invention relates to the technical field of coal blending. More specifically, the present invention relates to a method for blending coal based on a buffer bin of a transfer station. Background technique [0002] In order to adapt to market demand and make full use of coal resources, the port needs to mix different types of coal into a new calorific value coal to improve port handling efficiency. At present, the port generally adopts the method of mixing coal based on silos. The coal stored in different silos is conveyed to the same belt through a feeder for mixing coal, but the construction cost of silos is relatively high. For the coal in the open yard, the coal is mixed without a silo, and the stacker-reclaimer is directly transported to the belt conveyor for mixed coal. The accuracy of the mixed coal is low, and it is difficult to control the conveying capacity of the belt conveyor. Summary of the invention [0003] An object of the present ...
