Abstract
The utility model discloses an anti-breaking coal chute, which comprises a front wall of the chute and a vertical section of the chute, the utility model is characterized in that a closed coal platform is provided below coal falling point between the front wall of the chute and the vertical section of the chute. When conveyor belt of the belt conveyor throws coal flow to transfer chute quickly, part of lump coal will desposit on transfer chute platform to form a coal bed, continuously thrown lump coal falls on the deposit coal, then slides into transfer chute, in this way, lump coal will not break out due to throwing of coal flow onto metal wall of the transfer chute directly.
Description
One, technical field
The utility model relates to the device of a kind of material anti-crushing in transportation reprinting process, and the chute that prevents lump coal breaking when unloading coal is reprinted in transportation by specifically a kind of coal preparation plant.
Two, background technology
One of important physical character of raw coal is exactly that fragility is bigger, the widely used coal stream of coal preparation plant transports transfer chute at present, carry in the process in the coal circulation, because of coal flow velocity degree very fast, coal stream directly impacts the antetheca of metal chute, cause lump coal broken in a large number, thereby reduced lump coal rate, make enterprise be subjected to very big loss.
Three, summary of the invention
The purpose of this utility model is a kind of long-pending coal anti-crushing chute of design, makes to reprint the direct impact of coal stream on long-pending coal seam, plays the effect of protective buffering, thereby realizes the purpose of fast coal anti-crushing.
The utility model is achieved in that
Chute of the present utility model, mainly containing chute antetheca and chute vertical section forms, its key is, below coal is wandered a little between chute antetheca and the chute vertical section, establish the long-pending coal platform of an osed top, in coal stream transportation reprinting process, form a certain thickness long-pending coal seam on this platform, reprint coal stream and directly impact on long-pending coal seam, reduce impulsive force, thereby reduced the percentage of damage of lump coal.
Good effect of the present utility model is: simple in structure, convenient and practical, significantly reduced the lump coal loss of coal stream in transportation reprinting process, and improved economic benefit of enterprises.
Four, description of drawings
Accompanying drawing is running condition figure of the present utility model.
Five, the specific embodiment
As shown in drawings, the utility model outwards shifts out a segment distance with the chute antetheca 3 of former transfer chute, establishes a long-pending coal platform 4 below the drop point of coal stream 2 between chute antetheca 3 and the chute vertical section 5.The long-pending coal platform 4 of present embodiment is located at 200mm place, coal breakage point below, long 300mm, wide 300mm.When belt feeder head drum 1 drive belt is thrown to transfer chute fast with coal stream, lump coal is understood on some platform that is deposited in transfer chute 4, form a lamination coal seam, lump coal under constantly throwing drops on to slide then on the long-pending coal and falls in the transfer chute, so just can effectively avoid coal stream directly to throw to the metallic walls of transfer chute and cause lump coal breaking.
Claims (1)
1, a kind of long-pending coal anti-crushing chute comprises chute antetheca (3) and chute vertical section (5), it is characterized in that: the long-pending coal platform (4) of an osed top is established in coal stream (2) drop point below between chute antetheca (3) and chute vertical section (5).
