Abstract
A close sinter crusher belongs to the sinter crushing machine technology field, contains an oven cooling ash hopper, a sinter well located under the oven ash hopper. Under the sinter well is hung with a single roller sinter crusher, the upper of which is connected with the sinter well by the connection element, the bottom is connected with a water sealed pipe by the connection element, on the rear of the water sealed pipe is connected with an ash splashing pipe, on the outlet of the water sealed pipe is installed with a mobile door. The utility model doesn't use the sinter meshing device, but decreases the ash nozzle quantity, reduces the cost of the capital investment and the maintenance, saves the water and electricity power resource, lessens the labor effort, and ensures the oven running safely and economically.
Description
Technical field
The utility model relates to a kind of slag crusher, the sealed slag crusher that specifically a kind of power plant dry ash extraction pulverized-coal fired boiler deslagging is used.
Background technology
Existing boiler is the dry ash extraction pulverized-coal fired boiler, adopts dragveyer (submerged slag conveyor or screw cinder cleaner) deslagging, carries with waterpower after the fragmentation of single roller slag crusher then.Here the purpose of using dragveyer is to form water seal at boiler bottom, solves the boiler bottom problem of leaking out.And now use submerged slag conveyor quick abrasion, maintenance big, and screw cinder cleaner blocks and causes shaft coupling to damage after easily advancing hard thing, influence the normal operation of boiler, and power consumption is big, and water resource waste is serious.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, provides a kind of deslagging not use dragveyer, and maintenance is little, the sealed slag crusher of high efficiency.
Solve the problems of the technologies described above by the following technical solutions: a kind of sealed slag crusher, comprise the boiler furnace hopper, be positioned at the slag well of boiler furnace hopper bottom, it is characterized in that, the below suspention of described slag well has single roller slag crusher, and the top of this list roller slag crusher is connected with the slag well with connector, and the bottom is connected with water sealing (sealing water) pipe with connector, the rear portion of this water sealing (sealing water) pipe is connected with towards grey water pipe, and valve is equipped with in the exit of water sealing (sealing water) pipe.
According to technique scheme, compared with prior art, the utility model does not use dragveyer, reduces grey ditch nozzle quantity, can reduce investment and maintenance cost, and the conserve water electric resources reduces labour intensity, and guarantees the safe and economical boiler operation.The three friendly groups 6 in Tangshan
#After boiler adopted two band sealing slag crushers to carry out deslagging, it was normal to slag tap, and boiler operatiopn is not affected; Reduced by two grey ditch nozzles, reduce water consumption; Because of not using dragveyer, power consumption reduces; Maintenance cost and time decreased; Labor strength reduces; The site environment health is improved.Every used dragveyer of stove is pressed the 6kw power calculation, year economize on electricity 52560kwh, and 0.32 yuan/kwh of electric cost price, the Spring Festival holidays electricity charge are with 16819 yuan; Reduce by two nozzles, about 70080 tons of year water saving is pressed towards 0.20 yuan of/ton calculating of buck, and Spring Festival holidays water rate is with 14016 yuan; Annual about 20000 yuan of maintenance cost; To reduce expenses every year be 50835 yuan to every stove like this, and can to reduce expenses every year be 305010 yuan if six boilers are all used instead behind the band sealing slag crusher.
Description of drawings
Fig. 1 is the utility model overall structure schematic diagram.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
The utility model is improvements over the prior art, and improved position is to have cancelled the screw cinder cleaner of prior art.Concrete structure is referring to accompanying drawing 1, the utility model is by boiler furnace hopper 1, slag well 2, single roller slag crusher 4 compositions such as grade, slag well 2 is positioned at boiler furnace hopper 1 below, with steel wire rope and single roller slag crusher 4 of turnbuckle 3 suspentions, single roller slag crusher 4 is connected with slag well 2 usefulness flanges 9, adds asbestos board between single roller slag crusher 4 and slag well 2 and the water sealing (sealing water) pipe 5 below each boiler furnace hopper 1 slag well 2.The bottom of single roller slag crusher 4 is connected with water sealing (sealing water) pipe 5 with flange 8, water sealing (sealing water) pipe 5 back be connected towards grey water pipe 6, use towards grey water pipe 6 and carry out flushing cinder, valve 7 is installed in the outlet of water sealing (sealing water) pipe 5 additional, valve 7 is closed voluntarily because of gravity when anhydrous, slag.Broken laggard to go into water sealing (sealing water) pipe 5 washed away through single roller slag crusher 4 for the lime-ash that boiler combustion produces, and the valve 7 of closing automatically guarantees that again burner hearth bottom does not leak out.
Claims (2)
1, a kind of sealed slag crusher, comprise the boiler furnace hopper, be positioned at the slag well of boiler furnace hopper bottom, it is characterized in that, the below suspention of described slag well has single roller slag crusher, and the top of this list roller slag crusher is connected with the slag well with connector, and the bottom is connected with water sealing (sealing water) pipe with connector, the rear portion of this water sealing (sealing water) pipe is connected with towards grey water pipe, and valve is equipped with in the exit of water sealing (sealing water) pipe.
2, sealed slag crusher according to claim 1 is characterized in that, the top of described single roller slag crusher is connected with the slag well with flange, and the bottom is connected with water sealing (sealing water) pipe with flange.
