Description
Technical field
The present invention relates to a kind of higher suspension stalk fermentation extruding and discharging device and method, belong to methane engineering technology field.
Background technology
In stalk fermentation biogas engineering traditional at present, fermentation technique is more because the higher suspension characteristic of stalk causes after fermentation
The stalk not digested can not be excluded by traditional overflow mechanism, cause stalk waste residue in fermenting case drastically to increase extreme influence
The gas production of fermentation process and a large amount of free spaces for taking casing so that fermentation efficiency is substantially reduced.
The content of the invention
In order to solve the above-mentioned technical problem, the present invention provides a kind of higher suspension stalk fermentation extruding and discharging device, will can send out
Suspension stalk in ferment casing is removed, and is improved fermentation gas amount, is realized the stabilization and sustainable operation of straw methane engineering.This hair
It is bright to further relate to higher suspension stalk fermentation extruding and discharging method.
To achieve these goals, technical scheme is as follows：A kind of higher suspension stalk fermentation extruding and discharging device,
Including fermentation casing, it is characterised in that：Helix extrusion device is installed by support feet in the fermenting case body, the spiral is squeezed
Pressure device includes tilting the cylinder installed, and the cylinder is made up of outer cylinder body and inner barrel, and the outer cylinder body is enclosed on inner cylinder in vitro,
And there is gap between them, conveying worm be installed in inner barrel,
The cylinder is divided into negative pressure suction casing, helical feed section and extruding fillter section, and the cylinder is sucked from negative pressure
Section is gradually inclined upwardly to extruding fillter section, wherein, the negative pressure suction casing is located at the top in fermenting case body, extrudes fillter section
Reach fermenting case external, and discharge bucket is set in its end；
The upside of the cylinder of the negative pressure suction casing is provided with charging aperture, and the downside of the outer cylinder body of the negative pressure suction casing is provided with
Material sucking port, the material sucking port is connected by suction tube with the import of pipeline pump, and the discharge nozzle of the pipeline pump reaches fermentation casing
Bottom；
Annular is set in gap between the negative pressure suction casing and the outer cylinder body and inner barrel of helical feed section intersection
Baffle plate, the ring baffle separates the gap between negative pressure suction casing and the outer cylinder body and inner barrel of helical feed section；
Bar hole is distributed with the wall of the inner barrel of the extruding fillter section and negative pressure suction casing, and all bar holes are into spiral shell
Shape distribution is revolved, and with the hand of spiral of the helical blade of conveying worm on the contrary, the downside of the outer cylinder body of helical feed section
Exported close to the position of ring baffle provided with zymotic fluid；
The pitch that the conveying worm is located at the spiral in extruding fillter section is less than positioned at negative pressure suction casing and spiral transferring
Send the pitch of the spiral in section.
Using such scheme, adsorbed, the suspension stalk on casing top of fermenting is sucked in inner barrel, negative by pipeline pump
Suction casing is pressed, zymotic fluid enters outer cylinder body by the bar hole of inner barrel, is then pumped back to by pipeline in fermenting case body, to hair
Material in ferment casing carries out hydraulic mixing, can so save mechanical agitation.

The frictional force of stalk and inner barrel inwall is effectively increased in press filtration section, it is to avoid squeeze pressure excessive rear stalk and inner barrel
The idle running of inwall.
In such scheme：The spiral the tip of the axis of the conveying worm installs cutting blade, the cutting blade position
In the top of discharge bucket.When helical axis rotates, cutting blade rotation, stalk is entered to advance, and all cut, to recycle, such as
Make organic fertilizer.
In such scheme：Between the helical blade of conveying worm in negative pressure suction casing and the inwall of inner barrel
The helical blade and the inwall of inner barrel of gap≤0.5mm, the helical feed section and the conveying worm in extruding fillter section
Between gap be 3-4mm.The pitch ratio that the conveying worm is located at the spiral in extruding fillter section is located at negative pressure suction casing
Pitch with the spiral in helical feed section is small by 15%.The helical blade of conveying worm in negative pressure suction casing and inner barrel
Gap≤0.5mm between inwall, the stalk that can be will be attached to greatest extent on inner cylinder body wall is blown off, it is to avoid block bar hole.
Helical feed section and extruding fillter section in the helical blade of conveying worm and the inwall of inner barrel between gap be 3-
4mm, adds pitch and diminishes, and is conducive to the extruding of stalk moisture.
In order to realize above-mentioned second purpose, the technical scheme is that：A kind of higher suspension stalk fermentation extruding and discharging side
Method, it is characterised in that：Prepare higher suspension stalk fermentation extruding and discharging device according to any one of claim 1-7, in stalk fermentation
During, pipeline pump is opened, the suspension stalk and zymotic fluid on the fermentation casing top enter in inner barrel, in negative pressure suction
Section, zymotic fluid is eventually returned to the bottom of fermentation casing by the bar hole on inner barrel and then by material sucking port, suction tube, to hair
Material in ferment casing is stirred, and suspension stalk is then transported to extruding fillter section by conveying worm, herein by crowded
Discharged after pressure from discharge bucket, the zymotic fluid that extruding fillter section is squeezed out returns to fermenting case by bar hole, zymotic fluid behind outlet
In vivo.
Beneficial effect：The present invention is simple in construction, easy to use.According to result of the test, used in stalk fermentation biogas engineering
The floating encrustation phenomena of unreacted stalk in fermenting case is substantially reduced after the device, waste material formation can be extruded, will sent out during discharging
Zymotic fluid, which continues to flow back to fermenting case, is fermented.Pipeline pump can not only play to form the work that negative pressure sends into stalk waste residue charging aperture
With can more realize the effect of hydraulic mixing, the conventional mechanical mixing of substitution realizes the variety of applications of set of system two, greatly
To reduce the construction cost of straw methane engineering.Install easy, simple to operate, user does not need professional technique, simple training
Its operating technology can be grasped, easy to maintenance, fault rate is low, good reliability is safe.
