Abstract
The utility model relates to a slime water concentration and pipeline transportation device which aims to solve the problems that the conventional equipment can not operate continuously, and the slime concentration is not easy to control. The feed opening of a horizontal type spiral centrifuge of the device is communicated with a slime water pipeline through a mud pump, and the drainage outlet of the horizontal type spiral centrifuge is communicated with a return pipeline through a reflux pump; the discharge opening of the horizontal type spiral centrifuge is communicated with the feed opening of a spiral feeder; the discharge opening of the spiral feeder is arranged corresponding to a feed opening at the top of a slime stirring bin; and a discharge opening at the bottom of the slime stirring bin is communicated with a slime transport pipeline through a slime pump. The device provided by the utility model greatly simplifies the whole technological process, can operate continuous and provide convenience for slime flow control of a slime power station.
Description
Technical field
The utility model belongs to mechanical equipment technical field, relates to a kind of black water and concentrates and pipeline transporter.
Background technology
Coal slime is as the fuel of fluidized-bed combustion boiler, and the preparation of coal slime is the important step that influences the generating of coal slime power plant with carrying always.Traditionally, the black water underflow concentrates, prepare the coal slime process by the filter press press filtration then generally finishes in the coal washery, thereafter coal slime is transported in the coal slime canopy of coal slime power plant by scraper plate machine, loading machine, and then coal slime is transported to fluid bed boiler furnace by traditional conveying equipment, finish the front-furnace feeding of coal slime fluidized bed boiler.Because the preparation of coal slime belongs to different departments with using, and relates to metering, the clearing of slime content and the delimitation problem of working, cause the linking of technological process of whole process unobstructed inadequately, and hand labor intensity is big, working condition is abominable.In addition, in black water concentrated pressure-filtering process, though the board-like filtering equipment of employing can be handled fine coal slurry, it was about 25～30% coal slime slurry that the coal slime press filtration is become water content.Also there is significant disadvantages in this equipment: can only intermittently operated, can't turn round continuously, and the coal slime concentration that press filtration is come out is not easy control, and coal slime pipeline fed distance is not easy to regulate.
From the preparation of whole coal slime with use consideration, though technological process in the past is relatively reasonable at each subring joint, but there are shortcomings such as system is too complicated, press filtration can not move continuously, hand labor intensity big, system takes up an area of greatly, feature of environmental protection difference in total link.
Summary of the invention
The purpose of this utility model is exactly at the deficiencies in the prior art, provides a kind of black water to concentrate and pipeline transporter.
The utility model comprises horizontal spiral centrifuge, feeding screw and coal slime stir storehouse.The charging aperture of horizontal spiral centrifuge is communicated with the black water pipeline by slush pump, and the discharge outlet of horizontal spiral centrifuge is communicated with reflux line by reflux pump, and the discharging opening of horizontal spiral centrifuge is communicated with the charging aperture of feeding screw.The charging aperture setting at the corresponding coal slime stir storehouse of the discharging opening of feeding screw top is provided with agitating device in the coal slime stir storehouse, and the discharging opening of coal slime stir storehouse bottom is communicated with the coal slime transfer pipeline by coal slurrypump.
The utility model has overcome the shortcoming of prior art, has not only simplified whole process flow greatly, and whole device can move continuously, and makes things convenient for coal slime power plant that the coal slime flow is controlled.The utility model helps reducing and takes up an area of, and has reduced hand labor intensity, has also reduced equipment investment.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the concentrated pipeline transporter that reaches of a kind of black water comprises horizontal spiral centrifuge 3, feeding screw 4 and coal slime stir storehouse 5.The charging aperture of horizontal spiral centrifuge 3 is communicated with black water pipeline 1 by slush pump 2, and the discharge outlet of horizontal spiral centrifuge 3 is communicated with reflux line 9 by reflux pump 8, and the discharging opening of horizontal spiral centrifuge 3 is communicated with the charging aperture of feeding screw 4.The charging aperture setting at the corresponding coal slime stir storehouse of the discharging opening of feeding screw 45 tops is provided with agitating device in the coal slime stir storehouse 5, and the discharging opening of coal slime stir storehouse 5 bottoms is communicated with coal slime transfer pipeline 7 by coal slurrypump 6.
In the work, black water after slush pump 2 will concentrate by black water pipeline 1 is squeezed into horizontal spiral centrifuge 3, horizontal spiral centrifuge 3 carries out centrifugal dehydration with black water, and the coal slime slurry after the dehydration is delivered to coal slime stir storehouse 5 by feeding screw 4, and keeps stirring in coal slime stir storehouse 5.The moisture of deviating from after horizontal spiral centrifuge 3 dehydrations is back to the coal washery by reflux pump 8 and reflux line 9.By coal slurrypump 6 coal slime in the coal slime stir storehouse 5 is squeezed into coal slime transfer pipeline 7, be transported in the fluidized-bed combustion boiler then and burn.
When reality was practical, control entered concentration of coal slurry, and the black water solid content that requires to enter is more than 200g/L, and by the control centrifuge speed, the coal slime mass concentration was between 64～72% during the coal slime that obtains was starched.The flow-control of coal slime slurry is to realize by the reciprocating frequency that changes piston push rod in the coal slurrypump.This device adopts converter technique control centrifuge speed, thus the concentration of the coal slime that control obtains slurry; Coal slurrypump adopts high-pressure plunger pump, starches from coal slime storehouse suction coal slime by the reciprocating motion of piston push rod, then it is squeezed into conveyance conduit.
