Abstract
A circumferential friction transmission automatic-balancing sand scraper in a bioreactor automatically runs at the bottom in the anaerobic fermentation bioreactor, and is characterized in that sediments generated at the bottom in the anaerobic fermentation bioreactor and sands are scraped, are collected to a groove at the bottom of a bioreactor tank, and are discharged out of the tank through a desanding machine, and the material at the bottom in the bioreactor is stirred. The circumferential friction transmission sand scraper has the advantages of small driving motor powder, realization of overcoming of different resistances by a scraper plate, realization of automatic balancing under the action of a balancing weight without any power, low failure rate, and convenience in maintenance. An automatic-balancing sand scraper assembly 3 and a support 2 always on a driving friction wheel and do not miss one step, the sand scraper assembly 3 stably and reliably runs, and the circumferential friction transmission sand scraper is composed of the driving motor 1, the sand scraper assembly support 2, the automatic-balancing sand scraper assembly 3, a friction transmission assembly 4, the bioreactor tank 5 and a guiding wheel assembly 6.
Description
Technical field
Patent of the present invention is related to energy facilities field, proposes a kind of periphery frictional drive autobalance type sand scraper removing sand for anaerobic fermentation of biological reactor inner bottom part.
Background technology
Generally bioreactor inlet feed is free from sand, so bioreactor bottom is without removing sand, even if some sediments, it is also a small amount of, can be in a little deslagging branched pipe of bioreactor bottom cloth, deslagging branched pipe is aggregated into the total scum pipe reaching outside tank, then is emitted the sediment of bioreactor inner bottom part by the deslagging pump on total deslagging pipeline.
Shortage with China's many natural resourcess and exhaustion, traditions of the past economic model: resource-product-consumption-disposal of pollutants, the material one-way flow economic model being constituted just suffers exit, new Mode of Circular: resource-product-consumption-regenerated resources, the material iterative cycles flowing economic model of the almost zero-emission being constituted just is vigorously supported by country.
Promote most successful at present and produced the Mode of Circular example of economies of scale: the excrement dirt such as cattle manure being produced using plant, add biomass such as straw as fermentation raw material simultaneously, feces of farm and biomass are added to fermentation in anaerobic fermentation of biological reactor, produce biogas and biogas slurry and biogas residue, the biogas producing is through desulfurization, decarburization, dehydration, deacidification, threshing and siloxanes, after the techniques such as oxide, can be used for marsh gas power generation and directly to the gas-fueled vehicles supplemental natural gas energy, biogas slurry and biogas residue are the organic fertilizers required for good plant growing.
Although the material iterative cycles flowing economic model of above-mentioned almost zero-emission looks fine, but there is also a lot of technical bottlenecks: the excrement dirt such as cattle manure as plant produces contains a lot of sands, even if through pretreatment, also have a large amount of sands to flow in anaerobic fermentation of biological reactors, biomass can bioreactor inner bottom part produce sediment with and amass into large area duricrust at top.
Because microorganism provides suitable generation time and biochemical reaction environment in bioreactor to be given.Can't often keep in repair clear tank, slagging-off removes shell, or even because also contain noxious substance in tank, nor carries out range estimation and patrol and examine, the periphery frictional drive sand scraper that the present invention provides just is used to remove the sediment of bioreactor inner bottom part generation and sand, and stirred bioreactor inner bottom part material.
Content of the invention
The periphery frictional drive sand scraper that the present invention provides is in anaerobic fermentation of biological reactor inner bottom part automatic running, while the sediment producing anaerobic fermentation of biological reactor inner bottom part is scraped with sand to be pooled to and transports outside tank by sand removing machine again in the tank bottoms groove of bioreactor, one side stirred bioreactor inner bottom part material, the great advantage of this periphery frictional drive sand scraper is that motor power is little, scraper plate can overcome different resistances, without any power balancing weight effect under autobalance, continuous operation, fault rate is low, easy to maintenance, autobalance type strike-off assembly 3 and support 2 under gravity all the time land will not step on sky on friction pulley driving, assembly 3 of strike-ofing operates steadily reliability.
This periphery frictional drive sand scraper, by motor 1, scrapes slag assembly support 2, and autobalance type is strike-off assembly 3, frictional drive assembly 4, bioreactor tank body 5, and guide wheel assemblies 6 grade forms.
Motor 1 is explosion-proof reducing motor, reducing motor and bearing and bearing block, and shaft seal assembly etc. is arranged on outside bioreactor tank body, facilitates maintenance, and drive shaft reaches in tank and is fixed together with driving friction pulley 7, and support is arranged at explosion-proof reducing motor bottom.
Assembly support 2 of strike-ofing is welded into integral solder structure as Aranea using shaped steel, and frame bottom becomes arc-shaped for I-steel simmering and bending, rests on above driving friction pulley, several rows of assembly 3 of strike-ofing is connected to above Aranea network framework with connectors such as bolts again.
Autobalance type strike-offs assembly 3 by free bearing and bearing pin 10, the gimbal lever 11, balancing weight 12, scraper plate 13 forms, when some sandstones of bioreactor inner bottom part are excessive, or when forming hard sand dune, scraper plate 13 can lift to be crossed from sandstone or sand dune top, sandstone or sand dune are crossed, scraper plate 13 returns to original position under the action of gravity of balancing weight 12 again to be continued to scrape slag, without stuck inside sandstone front end or sand dune.By cover plate 14, rubber compact heap 15, sandstone 16, screw rod 17, nut 18, steel drum 19 forms balancing weight 12, according to requirements can arbitrarily adjust the weight of balancing weight 12 by increasing and decreasing the sandstone in steel drum 19.
Frictional drive assembly 4 is by driving friction pulley 7, support scroll wheel 8, roll wheel support 9 to form, both sides under friction pulley 7 are driven respectively to have a support scroll wheel 8, friction pulley 7 and autobalance type is driven to strike-off assembly 3 and support 2 for supporting, strike-off assembly 3 of autobalance type rests on above driving friction pulley 7 with support 2, strike-off assembly 3 of autobalance type is driven to rotate round bioreactor central axis with support 2 by driving friction pulley 7, scroll wheel 8 is supported to be arranged on above rolling wheel support 9, it is tank bottoms that rolling wheel support 9 bottom is fixed on bioreactor.
Bioreactor tank body 5 carries heat-insulation layer, heat-insulation layer heating pipe built-in road, has charging aperture, discharge gate, aerogenesis mouth, mouth spray and various sensor interface, agitator interface, manhole, sample tap etc..
Guide wheel assemblies 6 are made up of with guide wheel bracket directive wheel, and guide wheel bracket is fixed to above top tank structure, for being scraped slag assembly support 3 guide-localization.
