Abstract

The utility model provides a three -dimensional uninstallation feed spoon of coal conveying system for the coal flows the uninstallation. Three -dimensional uninstallation feed spoon passes through flange and coal conveying system coal breakage pipe sub -unit connection to deep to the baffle box in, be close to the belt, its lower part is the dilatation structure that leans forward, the discharge opening is the rectangle form, the front portion that its coal flows is equipped with the maintenance observation door, coal stream impingement surface is equipped with wear -resisting compound welt. The utility model discloses after can guaranteeing that coal stream gets into the three -dimensional feed spoon of uninstalling from the coal breakage pipe, the direction of motion that the coal flows obtains changing, the velocity of movement obtains reducing, it fully collects in three -dimensional uninstallation feed spoon to make the coal flow, in the same direction as the slipstream freely along softly the uninstall middle position of belt of the direction of motion of belt, the reduction is kicked up and the problem of impact nature chute blockage because of the coal flows the dust that causes with the impact of belt, the unbalance loading off tracking takes place when avoiding the belt to receive the material, and installation is simple, swiftly, safety and reliability, the volume of maintaining maintenance work is little, basically, non -maintaining, can greatly improve production efficiency, and extend the service life of the equipment, reduce the maintenance cost.

Description

Coal handling system three-dimensional unloading feed spoon
Technical field
The utility model is related to defeated coal transhipment delivery system technical field, specifically a kind of for power station, harbour, chemical industry, The coal handling systems such as metallurgy, mine join position coal stream unloading, coal stream collects the three-dimensional unloading feed spoon that changed course is transported.
Background technology
Collect water conservancy diversion unloading:Using physical method, the coal stream desultorily being carried out freely falling body shape motion is returned Hold together, assemble, arrange after so as to by design movement locus, be unloaded on next stage belt with less impulsive force.
Traditional coal handling plant is designed using the guiding theory of " material abrasive material ", and the design of this coal breakage tubular construction makes coal Stream excessively dispersion, free motion in running, the direction of motion of coal stream, movement velocity, angle of attack are in disorderly and unsystematic State, causes between coal stream, occurs brokenly mutually to impact, collide, extrude phenomenon, coal between coal stream and coal handling plant inwall Coal dust in stream a fluid stream, fine particle are activated and shake off out from coal stream a fluid stream, are free on aerial.When coal stream movement is to falling The lower part of coal pipe and unload entrance deflector chute belt when, the induced air constantly pouring in causes the shape of air positive pressure in deflector chute Become, now the air of barotropic state and the fine dusts in coal stream mutually merge, have been wrapped to form dust and gas, and flow to atmosphere. Due to shots not just, impulsive force causes greatly deflector chute serious wear, and coal stream is extruded with deflector chute binding site from belt, belt There is unbalance loading sideslip, spill coal, dust raising phenomenon, equipment attrition, deformation, high noise.
During material is unloaded to next stage material feeding system by upper level induction system, coal spout unloading part is its turn The throat thoroughfare of fortune process, is one of normal key link run of decision systems.Traditional coal spout and uninstalling portion are divided into Prevent the generation of chute blockage phenomenon, dump location sectional dimension is larger, and with belt close to vertical design, coal stream flow velocity and impact gesture Can be high, cause transfer station dust concentration during unloading exceeded, greatly, passage blocks noise because of impact, and belt and correlation set Standby service life is low, and stream direction is unstable, and belt occurs the drawbacks such as unbalance loading sideslip.
Content of the invention
For overcoming the deficiencies in the prior art, goal of the invention of the present utility model is to provide a kind of coal handling system three-dimensional unloading Feed spoon, to change the direction of motion of coal stream, reduces the flow velocity of coal stream, and coal stream is carried out collect, buffer after again along belt Traffic direction softly unloads.
For achieving the above object, three-dimensional unloading feed spoon of the present utility model passes through the coal breakage of flange and coal handling system Pipe bottom connects, and deeply to deflector chute, close belt;Three-dimensional unloading feed spoon changes the direction of motion and the speed of coal stream, Coal stream is made to collect in three-dimensional unloading feed spoon, the coal stream one being unloaded on belt occupy belt middle position with heaped-up.
The bottom of described three-dimensional unloading feed spoon is the volume expansion structure that leans forward, and discharge port is rectangular-shaped.
The front portion of the coal stream of described three-dimensional unloading feed spoon is provided with the maintenance being easy to coal stream mode is observed and observes door.
The coal stream shock surface of described three-dimensional unloading feed spoon is equipped with wear-resisting composite liner.
After coal stream enters coal spout by head funnel and moves under coal spout partly, coal stream enters three-dimensional unloading feed Spoon, three-dimensional unloading feed spoon can change the direction of motion of coal stream, slow down the movement velocity of coal stream, and coal stream is carried out collecting row Row, change the cross sectional shape of coal stream unloading, make speed, track that coal stream runs with approximate belt, according to the traffic direction of belt The smooth middle position being unloaded to belt glibly, makes the coal stream after unloading move along belt direction of travel, reduce because material with The impact of belt and the dust that produces is kicked up and the problem of impact chute blockage, it is to avoid belt unbalance loading sideslip.
The utility model compared with prior art it is ensured that coal stream is after coal spout enters three-dimensional unloading feed spoon, coal stream The direction of motion be changed, movement velocity is reduced, and so that coal stream is fully collected in three-dimensional unloading feed spoon, smooth Gently it is unloaded to the middle position of belt along the direction of motion of belt glibly, reduce because of coal stream and the impact of belt and make The problem that the dust becoming is kicked up with impact chute blockage, it is to avoid during belt material feeding, unbalance loading sideslip occurs, installs simple, quick, safety Reliable, maintenance work amount is little, substantially non-maintaining, can be greatly enhanced production efficiency, the service life of extension device, subtract Little maintenance cost.
Brief description
Fig. 1 is stereochemical structure sketch of the present utility model.
Fig. 2 is the stereochemical structure sketch of the other direction of Fig. 1.
Specific embodiment
As shown in Figure 1 and Figure 2, the utility model utilizes CAD, and unloading feed spoon 2 can change the fortune of coal stream 3 Dynamic direction and speed, make coal stream 3 collect in three-dimensional unloading feed spoon 2, the coal stream 1 being unloaded on belt 5 is occupied with heaped-up In belt 5 middle position it is ensured that reducing Dust Capacity when coal stream 3 is unloaded on belt 5, reduce to the impact of belt 5 and sideslip.
The bottom of described three-dimensional unloading feed spoon 2 is the volume expansion structure that leans forward(Lower volume is more than upper volume, anterior 10 edges The traffic direction of belt 5 turns forward), discharge port is rectangular-shaped, to reduce Dust Capacity, reduces the impact to belt 5.
The front portion 10 of the coal stream 3 of described three-dimensional unloading feed spoon 2(Non-percussion face)It is provided with maintenance and observes door 7, be easy to coal The state of stream 3 is observed.
Coal stream 3 shock surface of described three-dimensional unloading feed spoon 2(Other faces in addition to anterior 10)Equipped with wear-resisting composite liner 8, its main chemical is Cr7C3, has high wearability, and can be changed, and can improve the use of unloading feed spoon 2 Life-span and use safety.
