Abstract
The utility model relates to a blended coal crushing device and belongs to the technical field of coking coal treatment. The device mainly comprises a first conveying belt (1), a coal blending cabin (2), a second conveying belt (3), a crusher (4), a cabin entry belt (5), a furnace top coal cabin (6), a coal feeding car (7) and a coke oven (8), which are sequentially connected, wherein a composite pre-crusher (9) is arranged in front of the first conveying belt (1); a feeding belt (10) and a first grate screen (11) are arranged at a feed inlet of the composite pre-crusher (9); and a second grate screen (12) is arranged at feed inlets of the second conveying belt (3) and the crusher (4). The crushing granularity of over 90 percent of blended coal can be less than 3mm.
Description
Technical field
The utility model relates to coking coal processing technology field, particularly a kind of mixed coal reducing mechanism.
Background technology
The employed reducing mechanism of prior art is as shown in Figure 1, by first travelling belt 1 that connects successively, blending bunker 2, second travelling belt 3, disintegrating machine 4, warehouse entry belt 5, furnace roof coal bunker 6, add coal car 7 and 8 of coke ovens are formed.This device only is suitable for breakable coking coal.Yet along with being on the increase of coal, the used coal of coking needs adapted to bottle coal, lean coal and anthracite.Bottle coal, lean coal and anthracite all belong to difficult broken coal; And bottle coal, lean coal, anthracite coking behavior are nothing like coking coal; The fragmentation that mixes of these coals, usually coking coal is broken, and bottle coal, lean coal, anthracite and well not broken; And under the immixture of disintegrating machine, cause segregation, make the uniformity of mixing coal receive very big influence.In addition, old 84 coke ovens are made putting into operation of burnt equipment firm by ramming, the grinding particle size of coal is required more and more high, require less than 3mm greater than 90%, the prior art crusher system can not satisfy production requirement far away, presses for and transforms.
The utility model content
The utility model technical problem to be solved is to overcome deficiency of the prior art, and a kind of mixed coal reducing mechanism is provided, and the grinding particle size that can make the mixed coal more than 90% is less than 3mm.
In order to address the above problem, the utility model adopts following technical scheme:
A kind of mixed coal reducing mechanism comprises successively first travelling belt 1 that connects, blending bunker 2, second travelling belt 3, disintegrating machine 4, warehouse entry belt 5, furnace roof coal bunker 6, adds coal car 7 and coke oven 8; A combined type prebreaker 9 is arranged before first travelling belt 1, and the feed belt 10 and the first castor bar grizzl(e)y 11 have been installed by the charging aperture place of combined type prebreaker; The charging aperture place of second travelling belt 3 and disintegrating machine 4 is provided with the second castor bar grizzl(e)y 12.
The utility model has been installed a combined type prebreaker at first travelling belt, 1 front end, and bottle coal, lean coal and the anthracite of transporting carried out independent precrushing, and grinding particle size is reached about 80%.The castor bar grizzl(e)y is installed at charging aperture place at combined type prebreaker and disintegrating machine respectively, screens out bulk, has improved the feed conditions of disintegrating machine.The grinding particle size that use the utility model enables the mixed coal more than 90% is less than 3mm.Make burnt density firm by ramming and be improved, the crushing strength of coke has improved two points, and scuff resistance has reduced by 0.5 point, but every year nearly 1,000,000 yuan of additional income.
Description of drawings
Fig. 1 is the prior art constructions sketch map.
Fig. 2 is the structural representation of the utility model.
In the accompanying drawing: 1 first travelling belt; 2 blending bunkers; 3 second travelling belts; 4 disintegrating machines; 5 warehouse entry belts; 6 furnace roof coal bunkers; 7 add coal car; 8 coke ovens; 9 combined type prebreakers; 10 feed belts; 11 first castor bar grizzl(e)ies; 12 second castor bar grizzl(e)ies.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed explanation.
Accompanying drawing 2 is a kind of mixed coal reducing mechanisms, comprises successively first travelling belt 1 that connects, blending bunker 2, second travelling belt 3, disintegrating machine 4, warehouse entry belt 5, furnace roof coal bunker 6, adds coal car 7 and coke oven 8; A PFCH-1212 combined type prebreaker is arranged before first travelling belt 1, and the feed belt 10 and the first castor bar grizzl(e)y 11 have been installed by its charging aperture place; The charging aperture place of second travelling belt 3 and disintegrating machine 4 is provided with the second castor bar grizzl(e)y 12.
Claims (1)
1. mixed coal reducing mechanism comprises first travelling belt (1), blending bunker (2), second travelling belt (3), disintegrating machine (4), warehouse entry belt (5), the furnace roof coal bunker (6) that connect successively, adds coal car (7) and coke oven (8); It is characterized in that: a combined type prebreaker (9) arranged in that first travelling belt (1) is preceding, the feed belt (10) and the first castor bar grizzl(e)y (11) have been installed by the charging aperture place of combined type prebreaker (9); The charging aperture place of second travelling belt (3) and disintegrating machine (4) is provided with the second castor bar grizzl(e)y (12).
