Abstract
The utility model discloses a rotor plate eccentric motion mechanism of a helical dehydrator, which comprises a helical axis with vanes, stator plates and rotor plates, wherein the stator plates and the rotor plates are sleeved on the helical axis and are arranged in a staggered mode, and free gaps are left between the stator plates and the rotor plates. The rotor plate eccentric motion mechanism is characterized in that the rotor plates are arranged on a crank axle of the rotor plates, the crank axle of the rotor plates drives the rotor plates to move in radial direction, one end of the crank axle of the rotor plates is connected with an eccentric driving wheel, and the other end of the crank axle of the rotor plates is connected with a follow-up eccentric bearing. Because the eccentric motion mechanism drives the rotor plates to move in radial direction, the problem that the helical axis is seriously worn and has short service life caused by the rotor plate motion in radial direction by the butt joint of the vanes and the rotor plates of the helical axis in the prior art is solved.
Description
Technical field
The utility model relates to the sewage water filtration technical field, and particularly environment protection sewage is handled filter, and what further relate to is the eccentric motion mechanism of spiral dewaterer.
Background technology
Sewage disposal is important some in the environmental protection industry (epi), and existing effluent treatment and filtering device has centrifugal filtration, plate and frame filtration, belt to filter.Centrifugal filter rotating speed height wherein, noise is big, the energy consumption height.Plate and frame filtering machine structure complexity is taken up an area of greatly, and filter cloth is easily broken, operates loaded down with trivial details.The belt filter takes up an area of big, and consumed energy is big, fluctuation of service.Because these filters exist problem, can not adapt to growing environmental protection cause requirement.Therefore develop new effluent treatment and filtering device and be the focus that the sector can personnel be paid close attention to.
In order to solve the problems of the technologies described above, CN2885572Y discloses " a kind of spiral solid, liquid seperator " and CN2762865Y disclose " a kind of laminated spiral formula filter ".
Referring to Fig. 1 and Fig. 2, in the CN2885572Y patent, helical axis 3 is driven by motor 4 and does to slowly run.At mud outlet 1 place a back pressure is housed and adjusts plate 2, work the size effect of adjusting the mud outlet, be convenient to mud and efflux filter to the greatest extent.The blade diameter of helical axis 3 is with a plurality of circulation laminations outward, these a plurality of circulation laminations by encircle 5 surely, adjust piece 6, rotating ring 7 is formed.Per two have the piece 6 of adjustment and a rotating ring 7 between encircling 5 surely, and the helical axis 3 of rotation and fixed, moving two rings, 5, the 7 staggered filter bodies that are superimposed as constitute the filter screen space.Surely it is bigger than the blade external diameter of helical axis 3 to encircle 5 internal diameter, and the internal diameter that is encircled 5 rotating rings that are clipped in the middle 7 surely is slightly less than the blade external diameter of helical axis 3.Be furnished with groove on the internal diameter of rotating ring 7, this slotted eye diameter is greater than the blade external diameter of helical axis 3.When helical axis rotated, rotating ring 7 internal diameters were propped up and do radially to move about accordingly by the blade end of helical axis 3, so avoided deciding that rubbish stops up phenomenon between ring 5 and the rotating ring 7.The blade pitgh of helical axis 3 is arranged by effluent stream inlet 8 and is dwindled gradually to outlet 1, to strengthen sewage pressure.The total length of a plurality of circulation laminations is L, divides sewage to flow into enriching section L1 and mud discharge dewatering period L2.Enriching section L1 is just as coarse mesh, mud can be separated with moisture content moment.Dewatering period L2 is with the dwindling gradually of blade pitgh of outlet helical axis 3, be full of press in the mud in the helical cavity then increasing, fully drain moisture content after mud extrapolated.
Referring to Fig. 3 and Fig. 4, in the CN2885572Y patent, helical axis 3 is driven by motor 4 and does to slowly run.At mud outlet 1 place a back pressure is housed and adjusts plate 2, work the size effect of adjusting the mud outlet.The blade diameter of helical axis 3 is with a plurality of circulation laminations outward, these a plurality of circulation laminations by encircle 5 surely, adjust piece 6, rotating ring 7 is formed.Per two have the piece 6 of adjustment and a rotating ring 7 between encircling 5 surely, and fixed, moving two rings 5 of the helical axis 3 of rotation and staggered stack, 7 one-tenth are filtered bodies.Surely the internal diameter that is encircled 5 rotating rings that are clipped in the middle 7 is slightly less than the blade external diameter of helical axis 3.The internal diameter of rotating ring 7 can be smooth or have a recess.When helical axis 3 rotated, rotating ring 7 internal diameters were propped up and do radially to move about accordingly by the blade end of helical axis 3.Because rotating ring radially moves about, so avoided deciding that rubbish stops up phenomenon between ring 5 and the rotating ring 7.The interlobate space of helical axis 3 is arranged by effluent stream inlet 8 and is dwindled gradually or equate to outlet 1.
Above-mentioned two patents all are to rely on the blade drive rotating ring of helical axis 3 radially to move about, and can produce a friction between the blade of helical axis 3 and the rotating ring like this, and the time one is long, can cause the wearing and tearing aggravation of the blade of helical axis 3, makes the decline in service life of helical axis 3.
