Sludge agitation paver vehicleTechnical field
The present invention relates to sludge agitation equipment, especially relate to a kind of sludge agitation paver vehicle.
Background technology
Mud ultrahigh-temperature aerobic fermentation drying technique processing requirement:
1, the water ratio being applicable to the mud compound of ultrahigh-temperature aerobic fermentation drying technique technique is about 45% ~ 55%.The water ratio of the mud of usual sewage work is about less than 85%, organic content more than 50%, and be applicable zymotechnique, the mud of (water ratio about 85%) is added biological bacteria, supplementary carbon source (adjusting according to content organic in mud) and compound mix (first compound adopts flyash, the wood powder of mummification, edible fungi residues), carry out mix, the moisture of compound is adjusted to (45% ~ 55%).
2, the technology of mud ultrahigh-temperature aerobic fermentation mummification adopts slot type to stack, usual mud compound be highly 2.5 ~ 3.5 meters to putting, keep piling the leavening temperature of body to be suitable for.
3, in aerobic fermentation drying process because mud compound and biological bacteria fermentation reaction need consume a large amount of oxygen, need to adopt gap aerating system to provide surviving rate and the fermentation reaction efficiency of sufficient oxygen guarantee biological bacteria to mud compound, therefore must keep the ventilation property of piling mud compound in body, oxygen just can be made better to distribute in heap body.
4, the cycle of sludge aerobic fermentation mummification is usually 15 ~ 25 days (adjusting according to weather condition and attenuation degree), in period fermentation reaction process, continuous minimizing organic in mud and the continuous evaporation of moisture, the degree of compactness of the mud compound in heap body constantly becomes large, performance of ventilating constantly reduces, therefore need to turn over groove operation, mud compound is carried out again stack after secondary turns, enable the stacking that compound is comparatively fluffy, keep the ventilation property of mud compound in heap body, fermentation efficiency is provided.
The arm-type sludge stirring device of the open a kind of suspension of Chinese patent CN102284255A, comprise agitated pool, both sides, agitated pool top arrange guide rail, guide rail is installed driving wheel and follow-up pulley, follow-up pulley is arranged on walker, connected by drive shaft between driving wheel, drive shaft is connected with movable motor by walking transmission mechanism, hinge axis is installed in walker bottom, the upper end of hinge axis both sides and cantilever is hinged, stir shaft is installed in cantilever lower end, stir shaft installs agitating roller, agitating roller arranges stirrer gear, cantilever installs agitator motor, agitator motor is connected with stir shaft by stirring transmission mechanism, walker installs windlass, windlass is connected with cantilever by strand cable.
Summary of the invention
The object of the invention is to provide a kind of sludge agitation paver vehicle.
The present invention is provided with storage device, mud mix whipping appts, sludge transfer device, mud dispersing device, outfeed belt conveyor, vehicle and power set;
Described storage device is located on vehicle, mud mix whipping appts is located in storage device, sludge transfer device is located at storage device bottom outside, the mud import of sludge transfer device connects the sludge outlet of storage device, mud dispersing device and outfeed belt conveyor are located at storage device afterbody, the sludge inlet of mud dispersing device connects the sludge outlet of sludge transfer device, what the opening for feed of outfeed belt conveyor connect mud dispersing device breaks up sludge outlet, power set is located on storage device, the clutch end of power set and mud mix whipping appts, sludge transfer device, mud dispersing device and outfeed belt conveyor electrical connection, the discharge port height of described outfeed belt conveyor and orientation are by lifting rope transmission mechanism control, lifting rope transmission rig is provided with tackleblock, lifting rope and motor, one end of lifting rope is fixed on the tapping channel rear end of outfeed belt conveyor, and the other end of lifting rope is connected with motor through tackleblock.
Described storage device is provided with hopper.
Compared with existing sludge treatment device, the present invention has following outstanding advantages and technique effect:
1, the present invention is portable, before sludge fermentation groove opening for feed can be placed it in, contrast with traditional stationary installation, handiness is good, reduce the secondary shipment (adopt conventional fixed-type device, mud after mix, stirring, then is stacked to fermenter with forklift shipment) of mud compound, reduce cost, enhance productivity.
2, adopt mix whipping appts to carry out mix, stirring to mud, efficiency is high, effective.According to the character of mud, because mud is made up of (in mud table moisture content and off-balancesheet moisture content ratio about 7: 3) reactive monomer cell, containing the organism of more than 50%, and water ratio is high, light specific gravity, is a kind of pseudo-plasticity gel.Cell is broken, resistance to compression extreme difference easily, in stirring, extrusion process, mud and compound produce and rub, destroy mud cell walls, in cell table, water can ooze out in a large number, and the water ratio being applicable to the mud compound of ultrahigh-temperature aerobic fermentation drying technique technique is about 45% ~ 55%.And adopt traditional equipment, mud is after conventional fixed-type mix, whipping appts mix, stirring, after needing ground on the scene stacking in heaps, loaded and transported to fermenter by forklift again, period is destroyed due to mud cell walls, can water in a large amount of emigrated cell table, and the shipment of adding forklift produces secondary extrusion to mud, be difficult to the water ratio controlling mud compound, the requirement of mud ultrahigh-temperature aerobic fermentation drying process cannot be met.
3, because the present invention is portable, before sludge fermentation groove opening for feed can be placed it in, mud through mix whipping appts mix, stir through mud dispersing device mud compound to be beaten to spread again and become loose Granular sludge, directly carry stacking in fermenter Granular sludge through outfeed belt conveyor, what shorten water in cell table oozes out the time, avoid the shipment because of forklift to produce secondary extrusion to mud simultaneously, ensure that the shatter value of mud granule, oxygen supply for fermentation reaction provides good condition, improves fermentation efficiency.
4, tradition adopt the shipment of forklift to enter fermenter to mud compound to carry out heap high, whole shovel mud compound is poured in groove simultaneously, and quantity is many and concentrated, is difficult to the shatter value controlling mud in heap body, causes the poor air permeability of mud in heap body.And the outfeed belt conveyor that the present invention adopts possesses height adjustable, can regulate with the height of sludge body, and mud compound to be quantity few, continue charging, ensure that the shatter value of mud granule in heap body, oxygen supply for fermentation reaction provides good condition, improves fermentation efficiency.
5, in sludge aerobic fermentation drying process, continuous minimizing organic in mud and the continuous evaporation of moisture, the degree of compactness of the mud compound in heap body constantly becomes large, performance of ventilating constantly reduces, need carry out turning over groove operation, mud compound is carried out again stack after secondary turns, enable the stacking that compound is comparatively fluffy, keep the ventilation property of mud compound in heap body.Material forklift need be shipped to and fixedly turn after device turns by traditional technology, then stacks to fermenter with forklift shipment.And before treatment unit of the present invention directly can be placed on sludge fermentation groove opening for feed, material is turned, reduce the secondary shipment of mud compound, reduce cost, enhance productivity.
