Description
Technical field
The utility model relates in a kind of marsh gas fermentation processes, for the deslagging device of the suspension slag in fermenting caseAnd biogas fermentation case.
Background technology
Domestic and international big-and-middle-sized mixed material fermentation methane engineering adopts mostly to the cleaning of scum silica frost in fermenting case at present" infundibulate " overfall is discharged, and finds that the method can only clear up part lighter weight (than natural pond liquid matter in practiceAmount is light) floating residue, and in fermentate, the material of a large amount of quality heavier (approaching with natural pond liquid quality) suspendsIn the liquid of natural pond, cannot discharge from " infundibulate " overfall, long-term accumulated forms scum layer, hinders " funnelShape " the normal discharge of overfall, in the time that reaching certain thickness, scum layer also can affect the output of biogas. Not finallyObtain " taking off lid " cleaning that do not stop production, expend a large amount of manpowers and time, and security incident easily occurs.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides the biogas fermentation of the easy descum of a kind of energyDeslagging device. The second object of the present invention is to provide the biogas fermentation with this kind of biogas fermentation deslagging deviceCase
To achieve these goals, the technical solution of the utility model is as follows: a kind of biogas fermentation deslagging device,It is characterized in that: comprise the conveyor screw of installing that is inclined upwardly gradually from front end to tail end, carrying spiral shellThe cylinder extracorporeal set outer cylinder body revolving, gapped between described outer cylinder body and cylindrical shell, on described cylindrical shell, be distributed with filterHole, arranges slurries outlet in the bottom of outer cylinder body, the front opening of described cylindrical shell, and tail end arranges discharging chute,On the front end nozzle of described cylindrical shell, connect exntension tubs, at the front end nozzle of these exntension tubs, horn mouth is set, described inThe helical axis of conveyor screw extends to forward the front end of exntension tubs, and at the end of its extension shrunk-on disc,The inwall of the exntension tubs between described impeller and conveyor screw is along being circumferentially distributed with axially extended deflector, instituteA side of stating deflector is fixed on the inwall of exntension tubs, and opposite side extends to the center of exntension tubs near spiral shellSpin axis;
Described conveyor screw is divided into the pre-extruded segment of spiral and screw extrusion section from front to back, described screw extrusion sectionHelical axis be diminished shaft, its larger diameter end is near the tail end of conveyor screw.
In such scheme: the tail end of the helical axis of described conveyor screw is connected with reductor by shaft coupling.Reductor is connected with motor, for conveyor screw provides power.
In such scheme: the afterbody of the helical axis of described conveyor screw is set with cutter, this cutting cutter spacingIn the top of discharging chute import. The dry (one-tenth piece) that squeezed solid carbon dioxide divides under the effect of cutter by powderBroken, then discharge.
In such scheme: described filter opening is bar hole. Be difficult for so blocked.
Another object of the present invention is achieved in that a kind of biogas fermentation case, comprises fermenting case body, itsBe characterised in that: the biogas fermentation described in the tilted installation claim of described fermenting case body 1-4 any one goes outSlag device, wherein impeller is positioned under the top liquid level of fermenting case body, and the afterbody of described conveyor screw reaches to be sent outFerment case is originally external.
In such scheme: bracing frame is set for supporting the biogas fermentation dress of slagging tap in the bottom surface of fermenting case bodyPut.
Adopt such scheme, in use, impeller is positioned under the liquid level of fermenting case. Open motor machine, leafWheel is with certain speed continuous rotation, and the dreg slurry in fermenting case is constantly inhaled into, and through horn mouth, pushes toDeflector, through deflector water conservancy diversion, makes rotatablely moving of liquid become axially-movable, and then slag slurry is by sameThe conveyor screw of axle rotation upwards promotes, and enters the pre-extruded segment of spiral, when material moves upward, and slag slurryLiquid is squeezed in the pre-extruded segment of spiral of conveyor screw, and liquid is dual at thrust and the self gravitation of impellerUnder effect, be expelled to outer cylinder body from the filter opening of cylindrical shell, then discharge from the slurries outlet of outer cylinder body lower end, get back toIn fermenting case. Dry is continued to be promoted to screw extrusion section.
Screw extrusion section is designed to diminished shaft, and dry arrives helicla flute sky below in screw extrusion section owing to getting overBetween less, owing to being subject to the frictional force effect of helicoid and cylindrical shell, make the density of material increase gradually (thingMaterial is extruded), also squeezed pressing dry thereupon of its moisture, is even squeezed into piece, and squeezing effect is good.
Beneficial effect: biogas fermentation deslagging device of the present utility model under the effect of impeller constantly by fermenting caseInterior dreg slurry pushes conveyor screw, realizes slag liquid and separate in conveyor screw, and slurries are got back in fermenting case,Slag is discharged from. Generation scum silica frost, knot in big-and-middle-sized mixed material fermentation methane engineering fermenting case are thoroughly solvedShell, causes discharging difficulty, and gas production reduces, and the problem that maintenance cost is high, for mixed material biogas engineering is heldContinuous efficient operation provides reliable equipment guarantee, has wide promotion prospect.
