Abstract
The utility model provides a coal falling barrel of a coal transmission system transfer station, which relates to a coal mine material transmitting device. The prior power plant adopts coal falling barrels of a No.2 and a No.3 transfer stations in a coal transmission system B, the potential safety hazard exists and the operation is not reasonable. The coal falling barrel comprises two coal falling hoppers and a tee joint T, wherein, the two coal falling hoppers are a coal falling hopper A matched with a belt of a system A and a coal falling hopper B matched with a belt of a system B, the coal falling hopper B is connected with the tee joint T, one port of the tee joint T is connected with a bevel barrel B, the other port is connected with one port of a reversed tee joint T, another port of the reversed tee joint T is communicated with the coal falling hopper A, an exit of the reversed tee joint T is connected with a bevel barrel A. The coal falling barrel solves the problem of the single channel bottleneck, eliminates the potential hazard of the coal flow brushing the belt, improves the reliability of the safe operation of the device, reduces the maintenance fee of the device and prolongs the service life.
Description
Technical field
The utility model relates to material transfer equipments such as mine, colliery, is specially adapted to the coal conduit of power plant coal handling system.
Background technology
As shown in Figure 1; it is the important task in No. 5 and No. 6 machine conveying coal sources that the power plant is being undertaken with defeated coal B system; wherein No. 2, No. 3 the transfer point coal conduit both can flow to run coal bin with the coal of coal receiving bunker and coal yard; also the dump of coal receiving bunker can be stored in coal yard; and standby each other with A system No. 2, No. 3 transfer point equipment, to guarantee the unit safety smooth operation.The coal conduit of defeated coal B system transfer point exists following fatal hidden danger in the real-world operation:
(1) the coal breakage bucket 3 of No. 3 belt heads of No. 3 transfer points of B system and following threeway 4 thereof are the only way which must be passed of coal in the defeated coal B system, it is a single pass bottleneck, often need to change coal breakage bucket and threeway, during the B system must stop to go up coal, directly cause No. 5 and No. 6 machines stoppages in transit.
(2) head roll 1 of A system No. 3 first roads belt feeder in 2, No. 3 transfer points of defeated coal B system, with head roll 2 width between centerss of B system No. 3 first roads belt feeder be 1900mm, the diameter of cylinder is 1000mm, the through-flow width of design between two cylinders is 900mm, thickness of belt is δ=15mm, developed width is 870mm, and during coal, coal stream from top to down seriously washes away two belts in the operation.
(3) since two No. 3 belt rollers of 2, No. 3 transfer points of B system at a distance of too near, when on No. 3 belts of B system during coal, the parabola coal stream of 2.5m/s is very strong to the cylinder erosion damage of No. 3 belts of A system.
From above analysis as can be known, original design not only exists serious potential safety hazard and operation irrationality, and causes very big restriction to the repair and maintenance of equipment, has shortened the service life of equipment on the one hand, increase maintenance cost simultaneously, more be difficult to satisfy the demand that site safety is produced.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, a kind of coal conduit of coal handling system transfer point is provided, not only thoroughly solved the hidden danger that single channel bottleneck problem and coal stream wash away belt, and the coal path of getting of B system two-way belt is fully utilized, improved the reliability of equipment safety operation, reduce equipment maintenance cost, prolonged service life.
The utility model is achieved through the following technical solutions its goal of the invention.
A kind of coal conduit of coal handling system transfer point, comprise: with the belt of defeated coal A system, the coal breakage bucket that the belt of B system cooperates, with the threeway of coal breakage bucket bonded assembly, with the oblique tube of threeway bonded assembly, with the straight tube of oblique tube bonded assembly, it is characterized in that: described coal breakage bucket is provided with two: the B coal breakage bucket that the A coal breakage bucket that cooperates with the belt of A system cooperates with the belt of B system, B coal breakage bucket connects threeway, a port of threeway connects the oblique tube of B, another port connects port of threeway of same specification, another port of threeway is communicated with A coal breakage bucket, and the outlet of threeway is connected with the oblique tube of A.
The utility model compared with prior art, because displacement drive, increased a coal breakage bucket, make the coal breakage bucket of the belt below of adjacent two drum driven become single operating structure respectively, not only thoroughly solved the hidden danger that bottleneck single channel problem and coal stream wash away belt, and the coal path of getting of B system two-way belt is fully utilized, improved the reliability of equipment safety operation.Fall threeway owing to reasonably set up one, technical reform scheme is carried out not changing under the former attached coal conduit design size prerequisite, reduced expense, provide cost savings, easy access is safeguarded.
Description of drawings
Fig. 1 is the original design structural representation of coal handling system transfer point coal conduit;
Fig. 2 is a structural representation of the present utility model.
The utility model is further described by preferred embodiment below in conjunction with accompanying drawing.
The specific embodiment
As shown in Figure 2, a kind of coal conduit of coal handling system transfer point, coal conduit with No. 2 transfer points of defeated coal B system in power plant is an example, the 3PAa of A system belt 1 head head roll 1-1 and the 3PBa of B system belt 2 head head roll 2-1 move 1750.5mm after each in No. 2 transfer points of B system, and it is 5401mm that two head roll width between centerss are increased.Then on the ground again perforate No. 3 first roads belt head funnel 3-1 of A system and the B system No. 3 first roads belt head funnel 3-2 that makes of the steel plate of 16Mn is installed, use the threeway 4-2 of the bolt of M16 * 50 below the funnel 3-2 through 60 ° of flange connections, the port of threeway 4-2 connects tiltedly tube 5-2 of B, B tiltedly tube 5-2 connects the straight tube of B 6-2, another port connects the port of the 4-1 of falling the threeway of same specification, another port of the 4-1 of falling the threeway is communicated with A coal breakage bucket 3-1, the outlet of the 4-1 of falling the threeway is connected with the oblique tube of an A 5-1, and A tiltedly tube 5-1 connects directly tube 6-1 of A.(the angle of the following coal conduit of threeway is constant).Transform the back like this and eliminated the hidden danger that coal stream washes away belt on the one hand; On the other hand, do not influence the coal breakage of 2PBa to 3PAa and other coal handling system 7 after moving.
