Description
Technical field
The present invention relates to sludge drying field, and in particular to a kind of extruder of the strip sludge of negative-pressure suction.
Background technology
Because fuel cost and freight constantly rise violently, sludge treatment becomes more difficult and expensive at present.In order to anti-
The only diffusion of methane and carbon dioxide, while should not also allow pollution burden to be transferred to offspring from the point of view of long-term plan, Europe at present
Man of ally no longer allows dewatered sludge directly to fill.For the U.S. and China, it is straight also will progressively to abandon sludge from now on
Connect the disposal options of landfill.
Sludge can be incinerated, and remaining ashes are all inorganic substances, can carry out landfill stabilization.It is but many at this time
Nutriment can be lost.Know from the analysis of global phosphor resource storage capacity, can be limited as the phosphor resource of fertilizer.Because ashes
In contain each heavy metal species, therefore these ashes rich in phosphorus content generally can not be used directly as agricultural fertilizer.Although at present from
The method of recycling extracting phosphorus is many in ashes, but the price is very expensive for the phosphorus produced, also without commercial value.Sludge incineration produces
These ashes at present can only temporarily in special landfill yard, wait from now on phosphorus price rise after carry out exploitation recycling again.
Although dewatered sludge can be burned directly, since it is desired that evaporation moisture content can consume big calorimetric in this burning process
Energy.In addition dewatered sludge is frequently necessary to long distance transportation to burning (such as large-scale coal-fired plant), also must additionally consume at this time
Expensive fuel.
The sludge disposal method originally generally used is to carry out sludge recycling, i.e., directly as agricultural fertilizer.In some Europe
Continent country, such as Holland and Northern European countries, set permission pollutant load is so low, and in fact these municipal sludges have been
Can not possibly be agricultural.In the case that agricultural sludge allows, because sludge transportation range and expense are also being continuously increased, this
Treatment approach will become more and more difficult from now on.In the U.S., situation is somewhat different, as long as sludge disinfection can reach grade A, change can
To be used as agricultural fertilizer.
No matter sludge is recycled or is incinerated disposal, the water content in usual dewatered sludge is in 75-
85% scope, if becoming have no economic implications if long-distance transportation these moisture content.If dewatered sludge can be done in advance
Change is handled, such as from 25%DS desiccation to 90%DS, sludge weight will decrease to original 28%.The calorific value of dewatered sludge compared with
Height, similar lignite, carbon dioxide are in neutrality, and generative fuel can be used as to carry out cogeneration of heat and power.
Under this background, the quantity cumulative year after year of European sludge desiccation processing equipment.In recent years, in the U.S. with
State also begins to build sludge desiccation processing equipment.Freight can be not only reduced after sludge drying, and these desiccation are dirty
Mud also becomes easily simple when coal-fired plant or cement kiln carry out incineration disposal.
Existing sludge desiccation processing equipment mainly includes wet feed storehouse, screw pump, sludge extruder, desiccation host, ring wind
Wind turbine, chemical deodorizing tower, biofilter etc.；Wherein sludge extruder is common equipment, he sludge extrude into strips, with
Facilitate follow-up desiccation；But extruder of the existing sludge extruder with, without what difference, all sludge is at the same time
It is extruded, the molding effect of final sludge is generally all accumulated on a moving belt, and the gap between such sludge is limited, and is distributed not
Uniformly, the subsequently contact area with hot-air can be influenced, the final effect for influencing desiccation.
For such scheme there are the shortcomings that, it is necessary to provide a kind of new scheme to solve the problems, such as this.

The operation principle of the extruder of the strip sludge of negative-pressure suction：
Original state；A pair of of stripper plate 21 staggers, i.e., when the stripper plate 21 in left side is on the face of the top, the closure in left side
Cylinder 26 is in topmost；The stripper plate 21 on right side is in bottom, and the closure cylinder 26 on right side is in bottom；Or when the right side
The stripper plate 21 of side is on the face of the top, and the closure cylinder 26 on right side is in topmost；The stripper plate 21 in left side is in most lower
End, the closure cylinder 26 in left side are in bottom；
Stripper plate 21 using original state as left side is on the face of the top, and the closure cylinder 26 in left side is in topmost；
The stripper plate 21 on right side is in bottom, and the closure cylinder 26 on right side is in exemplified by bottom：Feed inlet 100, isocon at this time
The pre- storage material groove 102 on road 101, the extruding groove 103 in left side and both sides is full of sludge, then first lifting cylinder of a pair 22 in left side
The stripper plate 21 in left side and the closure cylinder 26 in left side is driven together to decline, then the sludge so in the extruding groove 103 in left side
Under the action of stripper plate 21, strip is shaped to by top discharge pipeline 110 and bottom discharge pipeline 311 and is extruded, last left side
A pair of second lifting cylinder 24 drives the closure cylinder 26 in left side to decline, and the closure cylinder 26 in left side plugs the top discharge to left side
In pipeline 110, the sludge in the top discharge pipeline 110 in left side is extruded, such strip sludge is transported to next by transfer device
Process；
In above-mentioned engineering, first lifting cylinder of a pair 22 on right side drives the stripper plate 21 on right side and the closure circle on right side
Column 26 together rises, since the closure cylinder 26 on the right side in this engineering is plugged in the top discharge pipeline 11 on right side always, with
The rising of the stripper plate 21 on right side, the extruding groove 103 on right side form negative pressure, and sludge is inhaled into the extruding groove 103 on right side, most
Second lifting cylinder of a pair 24 on right side drives closure cylinder 26 to rise to most significant end afterwards；
By above-mentioned operation principle, strip sludge is extruded in left and right in turn；Strip sludge is transported to down by transfer device
One process.
When the thickness of strip sludge needs to adjust, it is only necessary to remove the replacement branch of the bottom discharge pipeline 311 of improper diameter
Fagging 31, changes the replacement support plate 31 of the bottom discharge pipeline 311 of suitable diameter.
Above content is only the better embodiment of the present invention, for those of ordinary skill in the art, according to the present invention
Thought, there will be changes, this specification content should not be construed as to this hair in specific embodiments and applications
Bright limitation.
