Description
Technical field:
The utility model relates to a kind of slag equipment of scraping of removing air water separation surface floating matter, particularly relate to a kind of in the environment protection sewage treating processes with the slag equipment of scraping of the matching used removing air water of biological fluidized bed gas floatation separation device separation surface floating matter.
Background technology:
Biological fluidized bed claims that also bio-reactor is the efficient biological wastewater treatment technology of generally acknowledging in the world at present.Obtained using widely in China, present suite of equipment of taking as the leading factor with anaerobe fluidized reactor and aerobic organism fluidization reactor replaces traditional engineering construction and has become trend.Yet biological fluidized bed is to adopt anaerobic biological reactor or aerobe reactor all to be unable to do without the gas, liquid, solid separating technology when handling waste water, and in fluidisation air supporting process, because the biological continuous propagation and the accumulation of inert substance make the scum silica frost amount on the reactor water surface more and more.When these floating substance gassiness foams reach a certain amount of, will influence gas and overflow from liquid level.And the floating matter of these accumulation can cause acid galvanic corrosion to cause the equipment corrosion aging on the gas-liquid separation surface.Moreover, it also can influence the effluent quality of bio-reactor along with clear water flows out.Therefore must be at any time with its removing.The bio-reactor of present domestic use is a cylindrical structural all basically, and the scrape slag equipment supporting with it is the frame mode with central shaft mostly.So, must have the room requirement, make range of application have significant limitation the air flotation pool division center.And complex structure cost height, repair and maintenance is inconvenience also.Therefore, develop highly versatile and the matching used slag scraper of cylindrical air flotation pool, be that this field is thirsted for solving and a still unsolved difficult problem always.
The utility model content: the purpose of this utility model provides a kind of centreless shaft swinging skimming machine of floatation pond.Mainly be to solve existing poor, the complex structure cost height of air flotation pool slag scraper versatility, the problem of repair and maintenance inconvenience.
The technical solution of the utility model is as described below: this utility model comprises motor, speed reduction unit, mounting plate, key, gear, bearing pin, roll sleeve, lining, support roller, roller bracket, scraper plate, screw, adapter sleeve, mud-collecting slot, air flotation pool, swivel nut, back-up ring, ball, bearing, it be by on circular air flotation pool housing, be provided with by a plurality of support rollers and adjust adjustable wheel holding mechanism that axle forms and one roll the transmission rig realization by wheel holding mechanism rest and the tooth that is provided with scraper plate.
The utility model compared with prior art has the following advantages and positively effect:
1, rolls transmission rig owing to be provided with the tooth that has scraper plate, along with tooth rolls the revolution of transmission rig on wheel holding mechanism, the material that floating that swims on the bio-reactor gas-liquid separation surface along with rolling scraper plate that transmission rig drives, tooth is scraped in the mud-collecting slot in the air flotation pool, send into sludge sump by blow-off pipe then, thereby will float removings in time such as material, gas is overflowed as early as possible from liquid level, simultaneously the effluent quality that can avoid again causing acid galvanic corrosion and influence bio-reactor or air flotation pool.Meanwhile, this tooth rolls transmission rig and has replaced large-sized involute gear with bearing pin simple in structure and roll sleeve, realized the mechanical transmission of low speed, heavy duty, have power little energy consumption low, operate steadily reliably, effectively increase the service life, not only economy but also practical characteristics.And can adapt to that dust is many, the abominable Working environment of poor lubrication uses.
2, owing to be provided with adjustable wheel holding mechanism, by adjustings (promptly adjusting the gap between axle contained ball of one end and the rolling wheel support facade) to a plurality of adjustment axles of this mechanism, the fixed operating sleeve design centre can be adjusted to the air flotation pool design centre and coincide, thereby realize no mandrel positioned centrally function.Exempted the requirement that must have the room to the air flotation pool division center, guaranteed that the utility model is noiseless with air flotation pool in turning course.Range of application is more extensive, and versatility is stronger.
3, owing to pivoting part rolling wheel support of the present utility model and support roller, adjust and be rolling between axle and rolling wheel support facade, gear and the roll sleeve and contact, reduce friction, reduced energy consumption, realized the purpose that load shedding is energy-conservation.
4, the utility model has also that utility model is novel, simple and reasonable, reliable working performance, machinery driving efficiency high energy consumption are low, effectively improve service life of equipment, meet sewage treatment project equipment developing direction, suitable advantage such as apply in the industry.
