Abstract
The utility model discloses a powder coal gasification is dragveyer for stove, including the sediment storehouse that connects gradually, the dragveyer head, slag bath and clear water storehouse, the dragveyer head is connected with the slag bath slope, it installs in slag bath and dragveyer head to drag for the sediment link joint, install the drive assembly at dragveyer top of the head end, install the interior guide pulley in the slag bath, the return stroke riding wheel and the automatic overspeed device tensioner of hydraulic pressure that install on the slag bath form the gyration closed loop, at sediment storehouse top installation vibrations dewatering screen, the vibrations dewatering screen includes the dewatering screen and installs the shock dynamo in the dewatering screen below, increase the vibrations dewatering screen, carry out dehydration to the exhaust cinder, reduce the water content, simple device structure, therefore, the carrier wave prepaid electric energy meter is low in cost.
Description
Technical field
The utility model relates to a kind of dragveyer, particularly relates to a kind of powdered coal pressuring gasified stove dragveyer.
Background technology
Powdered coal pressuring gasified stove is a kind of type of furnace being adapted to burning low grade coal kind.Because its characteristic causes pulp water discharge capacity large, pulp water entered dragveyer slag bath once every 30 minutes, and each time length is approximately 2 minutes, and therefore the front storehouse of dragveyer slag bath in a short period of time, the slag that meeting repertory is a large amount of and pulp water.Due to slag be in coal ash content and a small amount of unburnt carbon at the solid particulate of molten state through water Quench, the chilled water recycled is the clinker water after filtration, its pH value is 6.5-9.0, and is dissolved with CO, CO2, H2S, NH3 and other metal ion and ammonium salt-containing, formate, carbonate, vitriol, the sulfide of trace.The slag that abrasiveness is stronger and the stronger clinker water of corrodibility, abrasive action when souring during excretion and slip is all stronger, the slag that vapourizing furnace lock hopper will be entered slag bath by dragveyer in maximum 25 minutes is pulled out, the thin slag of the clinker water drained with slag and the non-sedimentation of part overflows to storehouse after dragveyer slag bath, is then extracted out by slag pool pump and sends into clean unit.
Chinese patent CN103834443A discloses a kind of powdered coal pressuring gasified stove dragveyer, and the water content of deslagging is 50%, and water content is larger.
Utility model content
The utility model improves on above-mentioned patent basis, and increase vibrated and dehydrated sieve, carry out processed to the cinder of discharging, reduce water content, device structure is simple, with low cost.
The utility model solves the technical scheme that its technical problem adopts: powder coal gasification furnace dragveyer of the present utility model, comprise the slag storehouse connected successively, dragveyer head, slag bath and clear water storehouse, dragveyer head tilts to be connected with slag bath, dragging for slag carrier bar is arranged in slag bath and dragveyer head, be arranged on the transmission component of dragveyer crown end, be arranged on the inner guide pulley in slag bath, be arranged on the backhaul support roller on slag bath and hydraulic auto tensioner formation revolution closed loop, vibrated and dehydrated sieve is installed above slag storehouse, vibrated and dehydrated sieve comprises draining screen and is arranged on the vibration motor below draining screen.
As preferably, draining screen is graticule mesh, and graticule mesh diagonal lines is 1mm, and vibration motor power is 0.75kw.
Vibration motor adopts fire proof motor.
The beneficial effects of the utility model are:
Powder coal gasification furnace dragveyer of the present utility model, carries out processed to the cinder pulled out, reduces water content, transforms existing dragveyer, increases vibrated and dehydrated screen sections, simple in structure and low in cost.
Accompanying drawing explanation
Fig. 1 is powder coal gasification furnace dragveyer structural representation of the present utility model.
In figure: 1. slag storehouse; 2. dragveyer head; 3. slag bath; 4. clear water storehouse; 5. vibrated and dehydrated sieve; 6. drag for slag carrier bar; 7. transmission component; 8. inner guide pulley; 9. backhaul tugboat; 10. hydraulic auto tensioner; 51. draining screens; 52. vibration motors.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment 1
See Fig. 1, powder coal gasification furnace dragveyer of the present utility model, comprise connect successively slag storehouse 1, dragveyer head 2, slag bath 3 and clear water storehouse 4, dragveyer head 2 tilts to be connected with slag bath 3, dragging for slag carrier bar 6 is arranged in slag bath 3 and dragveyer head 2, be arranged on the transmission component 7 on dragveyer head 2 top, the inner guide pulley 8 be arranged in slag bath 3, be arranged on backhaul support roller 9 on slag bath 3 and hydraulic auto tensioner 10 forms revolution closed loop, vibrated and dehydrated sieve 5 is installed above slag storehouse 1, the vibration motor 52 that vibrated and dehydrated sieve 5 comprises draining screen 51 and is arranged on below draining screen 51.
Draining screen 51 is graticule mesh, and graticule mesh diagonal lines is 1mm, and vibration motor 52 power is 0.75kw.
Vibration motor adopts fire proof motor.
Powder coal gasification furnace dragveyer of the present utility model, carries out processed to the cinder pulled out, reduces water content, transforms existing dragveyer, increases vibrated and dehydrated screen sections, simple in structure and low in cost.
