Abstract

The utility model discloses a spiral stirring methane -generating pit, including between fermentation vat, feed inlet and water pressure, still including preventing the dross assembly, prevent that the dross assembly includes drift net, spiral plate, lifter and drive turntable, the rich lifter of spiral plate is helical configuration makes its face form slope, is provided with on the spiral plate to permit the discharge orifice of crossing that the feed liquid flows past. Drift net prevents that the dross from floating to the upper surface crust of feed liquid, drive turntable drive lifter drives spiral plate ascend spirally, realizes can also preventing to the stirring that the feed liquid is even, abundant that the spiral plate from reciprocating the too fierce methanogen's of influence existence, resistance during crossing the discharge orifice and can reduce the spiral plate and go up and down on the spiral plate can form fluid passage reinforcing stirring effect in addition.

Description

Screw mixing methane-generating pit

Technical field

This utility model is related to a kind of methane-generating pit, more particularly to a kind of screw mixing methane-generating pit.

Background technology

Hydraulic type biomass pool is that China promotes the most pond shape of earliest, quantity, and its cell body structure tension performance is good, and The bearing capacity that allows of spy is made full use of, so labor and material saving, cost is suitable to load various fermentation raw materials, particularly greatly than relatively low The crop material of amount, often feeds for ease of Jing, and lavatory, pigsty can be built in above methane-generating pit, and feces can be swept at any time into pond. Place under static state, just occurs lamination to methane-generating pit for a long time.Scum layer, supernatant layer, active layer, sediment can be typically divided into Four layers of layer.Scum layer fermentation raw material is more, and biogas strain is few, and raw material can also affect biogas using insufficient in addition, scum silica frost is blocked up Enter air inlet chamber.Supernatant layer washiness, fermentation raw material are few, and biogas antibacterial is also few, is not likely to produce biogas.Active layer is anaerobe The vigorous place of activity, is the significant points for producing biogas.Although bottom sediment layer has biogas antibacterial, but most raw materials do not have The standby condition for producing biogas.

Prior art mainly solves above-mentioned technical problem by the way of stirring, but due to methanogen have it is preferably quiet not The characteristic preferably moved, stirring excessively frequent or fierceness are unfavorable for the existence of methanogen so as to affect the generation of biogas, stirring frequency Too low anti-scum silica frost effect can be affected again.

Utility model content

In view of this, the purpose of this utility model is to provide a kind of new screw mixing methane-generating pit, is produced in anti-scum silica frost The existence of methanogen is not interfered with while raw.

The purpose of this utility model is achieved through the following technical solutions：

Screw mixing methane-generating pit of the present utility model, including fermentation vat, charging aperture and water pressure chamber, at the top of the fermentation vat Closure to be opened/closed and airway are provided with, the charging aperture and water pressure chamber are connected with fermentation vat bottom respectively, also including anti- Scum silica frost assembly, the anti-scum silica frost assembly include drift net, spiral lamina, elevating lever and driving rotating disk；

The drift net swims in the upper surface of liquid material in the fermentation vat；

The elevating lever is vertically arranged at the center of fermentation vat, and the elevating lever is connected with the screw top of the fermentation vat Connect, the elevating lever is slidably connected to the drift net along its own axial single-degree-of-freedom；

The spiral lamina is fixed on the elevating lever lower end, and structure makes its plate face to the rich elevating lever of the spiral lamina in the shape of a spiral Slope is formed, the flowing hole for allowing feed liquid to flow through on the spiral lamina, is provided with；

The center of the driving rotating disk is fixedly installed on the upper end of the elevating lever.

Further, a diameter of 150mm-200mm of the radial section of the flowing hole.

Further, Anti-slip cover is provided with the driving rotating disk.

The beneficial effects of the utility model：Screw mixing methane-generating pit of the present utility model, drift net prevent scum silica frost from floating Upper surface to feed liquid crusts；Driving rotating disk drives elevating lever to drive spiral lamina spiral escalation, realizes uniform to feed liquid, abundant Stirring, moreover it is possible to prevent spiral lamina from moving up and down the excessively fierce existence for affecting methanogen；Flowing hole on spiral lamina can be with Reducing resistance when spiral lamina is lifted, and can form fluid passage strengthens mixing effect.

Description of the drawings

With reference to the accompanying drawings and examples this utility model is further described：

Fig. 1 is structural representation of the present utility model.

Specific embodiment

Fig. 1 is structural representation of the present utility model, as illustrated, in the present embodiment, of the present utility model spiral Stirring methane-generating pit, including fermentation vat 1, charging aperture 9 and water pressure chamber 6, are provided with 2 He of closure to be opened/closed at the top of the fermentation vat Airway 5, the charging aperture 9 and water pressure chamber 6 are connected with 1 bottom of fermentation vat respectively, in the present embodiment, water pressure chamber 6 and fermentation vat 1 Connected by the conduit 7 of bottom, it is also possible to connect otherwise, the screw mixing methane-generating pit of the present embodiment also includes preventing Scum silica frost assembly, the anti-scum silica frost assembly include drift net 10, spiral lamina 8, elevating lever 3 and driving rotating disk 4；

The drift net 10 swims in the upper surface of liquid material in the fermentation vat, drift net 10 can using spear material etc. is any can To swim in the material on liquid material surface, it is prior art, does not repeat herein；

The elevating lever 3 is vertically arranged at the center of fermentation vat 1, and the elevating lever is connected with the screw top of the fermentation vat Connect, the elevating lever 3 is slidably connected to the drift net 10 along its own axial single-degree-of-freedom；With using dovetail groove, T-slot etc. Structure is realized being slidably connected, and can realize the purpose of the present invention；

The spiral lamina 8 is fixed on 3 lower end of the elevating lever, and structure makes its plate to the rich elevating lever of the spiral lamina in the shape of a spiral Face forms slope, and the flowing hole 8-1 for allowing feed liquid to flow through is provided with the spiral lamina；

The center of the driving rotating disk 4 is fixedly installed on the upper end of the elevating lever 3.

Spiral lamina 8 is horizontally disposed with, and it is hemispherical that 1 bottom of fermentation vat is cylindric top, and driving rotating disk 4 passes through elevating lever 3 8 spiral lift of spiral lamina is driven, stirring uniform to feed liquid, sufficient can be realized；Spiral escalation can more slowly be prevented 8 vigorous exercise of spiral lamina affects the existence of methanogen.

In the present embodiment, a diameter of 150mm-200mm of the flowing hole 8-1 radial sections；Good liquid stream can be formed Passage can preferably reduce resistance when spiral lamina 8 is lifted again.

Anti-slip cover is provided with the driving rotating disk.
