Description
Technical field
The utility model relates to the dredger in a kind of material conveying process, relates to a kind of device making the mass transport of coal bunker unobstructed or rather.
Background technology
Current most of coal bucket structure is infundibulate, charging suitable for reading, end opening discharging, and material falls by deadweight from top to bottom, and more flow downward, flow area is less, and the friction force between material, between material and headwall and squeese pressure are larger; When material particles is little, ash large, high humidity, viscosity are large, flowing power is poorer, and therefore, frequent blockage phenomenon, affects follow-up equipment safety, economical operation.Particularly at thermal powerplant, raw coal bucket material latch up phenomenon often occurs, and has a strong impact on safety in production.
For blocking, there is many defects as vibrator, artificial sledgehammer, air bubble, loosening machine etc. in conventional processing method, can alleviate to a certain extent, fundamentally can not eliminate fault, particularly wet coal, tough coal etc. are seemed helpless especially, thus bring very big inconvenience to production.And the belt conveyor of existing feeder operationally often makes material overflow from belt, and uneven is deposited in both sides, feeder bottom, make troubles to normal production.
Summary of the invention
The purpose of this utility model is to provide a kind of integrated anti-blocking block clearing coal bunker for the deficiencies in the prior art, coal charge can be made to carry unobstructed.
Technical scheme described in the utility model is: described coal bunker bottom connects insertion plate door, the coal supply machine transplanting of rice is set between described insertion plate door and feeder and enters formula sealed expansion joint, described coal bunker outside installs 2-8 silo wall vibrating air hammer additional, and wherein 2 are arranged between insertion plate door and plug-type sealed expansion joint of coal feeder; Described coal bunker headwall arranges manhole door; Described silo wall vibrating air hammer connects automatic filtering drainage device, it is characterized in that the coal spout extending run coal bin directly inserts in feeder, the upper zone face of the contiguous load-transfer device of lower nozzle of described coal spout is arranged, coal spout offers breach, and described breach is arranged in the edge of the coal spout lower nozzle at the throughput direction place of load-transfer device.
During the utility model application, 5-7 rice above run coal bin hypomere to feeder is removed, changes cost apparatus.
As shown from the above technical solution, the coal bunker of setting can reduce drag and the friction force of the displacement of raw coal whereabouts, prevents chute blockage; The bidirectional electric arranged or manual inserting plate door not easily chute blockage, can block coal stream, convenient maintenance; What the plug-type sealed expansion joint of coal feeder arranged can alleviate that raw coal bucket causes due to climate change expands with heat and contract with cold, and can not hide coal; When the coal charge in coal bunker falls, coal charge is caught up with along breach place place and is extruded coal spout by the conveying effect of load-transfer device, the ulking thickness of coal charge is limited to the height of breach, breach plays the shaping operation to coal charge thickness, therefore, coal charge can be arranged on the conveyor belt uniformly, and along tape transport in boiler.Therefore, the utility model can solve the operating fluffy coal of raw coal bucket, chute blockage phenomenon effectively, has a good application prospect.

In figure, 1. run coal bin, 2. coal bunker, 3. automatic filtering drainage device, 4. manhole door, 5. silo wall vibrating air hammer, 6. insertion plate door, 7. plug-type sealed expansion joint of coal feeder, 8. feeder, 9. coal spout, 10. breach, 11. deflecting plates, 12. load-transfer devices, 13. inspection doors.
Detailed description of the invention
As shown in Figure 1, below run coal bin 1, coal bunker 2 is connected.Described coal bunker 2 lower end connects insertion plate door 6, and arrange the coal supply machine transplanting of rice between described insertion plate door 6 and feeder 8 and enter formula sealed expansion joint 7, the coal spout 9 sections of run coal bin 1 directly inserts in feeder 8; Described coal bunker 2 outside installs 2-8 silo wall vibrating air hammer 5 additional, and wherein 2 are arranged between insertion plate door 6 and plug-type sealed expansion joint of coal feeder 7; Described coal bunker 2 headwall arranges manhole door 4; Described silo wall vibrating air hammer 5 connects automatic filtering drainage device 3.Described coal bunker 2 is 8 joints, and material is the stainless steel sheet of thickness 6-15mm or stainless iron plate.Described insertion plate door 6 is Bidirectional electric plug-board door or Bidirectional manual inserting plate door.
Coal spout 9 extends in rear direct insertion feeder 8.The upper zone face of the contiguous load-transfer device 12 of lower nozzle of described coal spout 9 is arranged, the upper zone face 10-50mm of lower nozzle distance load-transfer device 10, with 30-50mm as well.Coal spout 9 offers breach 10, described breach 10 is arranged in the edge of coal spout 9 lower nozzle at the throughput direction place of load-transfer device 12.
Shown in composition graphs 2, the lower nozzle edge of described coal spout 9 is provided with breach 10 and the top of contiguous load-transfer device 12 is arranged, when the coal charge in coal bunker falls, coal charge is caught up with along breach 10 place place and is extruded coal spout 9 by the conveying effect of load-transfer device 12, the ulking thickness of coal charge is limited to the height of breach 10, and breach 10 plays the shaping operation to coal charge thickness, therefore, coal charge can be arranged on load-transfer device 12 uniformly, and be delivered in boiler along load-transfer device 12.
As concrete embodiment, the profile of described breach 10 is in " U " shape and opening points to below.The breach 10 of " U " shape should form the wicket mouth that coal charge passes through, coal charge is when piling up appears in coal spout 9, under the conveying effect of load-transfer device 12, coal charge is extruded outside coal spout 9 along the breach 10 of " U " shape, and coal charge conforms in the cross section profile of the accumulation of load-transfer device 12 with the profile of breach 10.Described " U " shape with semicircular arc as well.
Further, the tube wall of the coal spout 9 at the place, both sides of described breach 10 is provided with two deflecting plates 11, described two deflecting plates 11 lay respectively at the both sides of load-transfer device 12, two deflecting plate 11 length directions are postponed along the throughput direction of load-transfer device 12 the upper zone face of layout and the contiguous load-transfer device 12 of lower edge, equally, two deflecting plates 11 apart from the upper zone face 10-50mm of load-transfer device 12, with 30-50mm as well.Two deflecting plates 11 play the barrier effect to coal charge, avoid coal charge to run from load-transfer device 12 and fall.Two described deflecting plate 11 length 100-150cm, can be rectangle, trapezoidal or triangle.
The upper zone face close together of the contiguous load-transfer device 12 of the lower nozzle due to coal spout 9, can not form the angle of sticky coal at the lower nozzle of coal spout 9 and two deflecting plates 11, i.e. not chute blockage.
Described two deflecting plates 11 also can form the adjustable of vertical direction with coal spout 9 and coordinate, to regulate the lower edge of both sides deflecting plate 11 and the optimum distance of load-transfer device 12.
As shown in Figure 3, establish an inspection door 13 on the lower nozzle of coal spout 9, the opposite of breach 10, namely cut one piece of elliptical flat-plate as hole door 31, the periphery welding gusset 32 of hole door 31, the installation hinge 33 of gusset 32; The tube wall of the coal spout 9 relative with hinge 33 is welded with bolt 36, and bolt 36 is threaded U-shaped pressing plate 34, and U-shaped pressing plate 34 is fastening with screw 35.This inspection door 13 shuts rear inside and original coal spout 9 wall fits like a glove, and namely meets the needs of overhaul of the equipments such as deflecting plate 11 grade, observation, can not block material again.
