Slag removal system at the bottom of vertical
Technical field
The utility model relates to slag removal system of a kind of end, slag removal system at the bottom of the vertical that particularly a kind of coal-fired boiler in thermal power plant is used.
Background technology
At present, the end slag removal system that coal-fired boiler in thermal power plant adopts, is by water immersion type scraping board slag conveyor or air-cooled slag extractor, end pulp water flat raft to be gone out mostly, is then delivered to sludge-store cabin top by the inclination section of climbing, and finally directly falls into sludge-store cabin.Because the inclination section of climbing is subject to the restriction at angle of inclination, this system configuration mode exists and takies larger ground domain space, and the high problem of cost of the section of climbing that tilts.
Summary of the invention
The utility model provides slag removal system at the bottom of a kind of vertical, has solved the high technical problem of large cost that takes up room that end slag removal system that existing coal-fired boiler in thermal power plant adopts exists.
The utility model is to solve by the following technical programs above technical problem:
Slag removal system at the bottom of a kind of vertical, comprise slag well, water immersion type scraping board slag conveyor and sludge-store cabin, bottom at slag well is provided with sliding door, under the sliding door arranging in the bottom of slag well, be provided with water immersion type scraping board slag conveyor, between water immersion type scraping board slag conveyor and sludge-store cabin, be provided with vertical bucket elevator, between the top of vertical bucket elevator and the top of sludge-store cabin, be provided with bottom ash conveying cylinder, the delivery outlet of water immersion type scraping board slag conveyor is arranged on the porch of the elevator bucket of vertical bucket elevator.
On the delivery outlet of water immersion type scraping board slag conveyor, be connected with slag guiding trough.
The purpose of this utility model is for the deficiencies in the prior art, and slag removal system at the bottom of a kind of novel vertical is provided, and effectively solves water immersion type scraping board slag conveyor or the air-cooled slag extractor section of climbing that tilts and invests the problems such as high, floor space is large.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is elaborated:
Slag removal system at the bottom of a kind of vertical, comprise slag well 1, water immersion type scraping board slag conveyor 3 and sludge-store cabin 5, be provided with sliding door 2 in the bottom of slag well 1, under the sliding door 2 arranging in the bottom of slag well 1, be provided with water immersion type scraping board slag conveyor 3, between water immersion type scraping board slag conveyor 3 and sludge-store cabin 5, be provided with vertical bucket elevator 4, between the top of vertical bucket elevator 4 and the top of sludge-store cabin 5, be provided with bottom ash conveying cylinder 6, the delivery outlet of water immersion type scraping board slag conveyor 3 is arranged on the porch of the elevator bucket of vertical bucket elevator 4.
On the delivery outlet of water immersion type scraping board slag conveyor 3, be connected with slag guiding trough 7.
The end slag of discharging from boiler bottom, fall into slag well 1 by Action of Gravity Field, in the time having that slag falls at the end, sliding door 2 is opened, end slag is fallen on water immersion type scraping board slag conveyor 3 or air-cooled slag extractor, discharges and deliver on vertical bucket elevator 4 by water immersion type scraping board slag conveyor 3 or air-cooled slag extractor level, by vertical bucket elevator 4 by end slag vertical-lift to sludge-store cabin 5 tops, finally, due to the rotation of belt pulley, the end slag in bucket directly falls into sludge-store cabin 5.
