Abstract
The utility model discloses a solid-liquid separation machine, relating to solid-liquid separation technology is provided, in particular belonging to a filtration device of environmental protection sewage treatment filed is provided, including geostationary rings, mobile rings and a screw axis; wherein, the staggered geostationary rings and the mobile rings are set up on the radial screw axis; the innovation point of the invention rests with a clearance is set up between the geostationary rings and the mobile rings, moreover a flange is set up on the inner diameter of the mobile ring. The utility model adopts several staggered geostationary rings, tab, the mobile rings and the screw axis as filter body, and makes use of screw axis vane to press the sludge continuously, and then a great deal of sludge and water are discharged outwards from the filter body quickly. The utility model is applicable for both small and medium-sized sewage treatment plant and large sewage treatment plant.
Description
Technical field
The utility model relates to solid-liquid separation technique, belongs to the filter of environment protection sewage process field especially.
Background technology
China utility model patent CN2762865Y discloses a kind of laminated spiral formula filter on 03 08th, 2006, comprise helical axis, blade diameter outside at helical axis is with a plurality of circulation laminations, these a plurality of circulation laminations are by fixed ring, rotating ring, adjusting piece forms, the arrangement of a plurality of circulation laminations is by between the per two fixed rings piece of adjustment and a rotating ring being arranged, the internal diameter of fixed ring is greater than the blade external diameter of helical axis, the internal diameter of rotating ring is less than the blade external diameter of helical axis, be furnished with notch on the rotating ring internal diameter greater than the spiral shaft vane external diameter, helical axis is with fixed, the staggered filter body, rotating ring internal diameter and radially moving about that the spiral shaft vane end props up mutually and is interrupted of being superimposed as of moving two rings.
The technical scheme utilization filter body that above-mentioned utility model patent provides pushes repeatedly with the blade pitgh of helical axis and dwindles gradually, to strengthen blowdown power, can handle the sewage of low concentration.Have that energy consumption is low, friction, noiseless, be suitable for the advantage of middle-size and small-size sewage disposal scale.But the deficiency of its existence also is conspicuous, specifically comprises:
1, the internal diameter of rotating ring is less than the external diameter of spiral shaft vane, rotating ring rubs with spiral shaft vane all the time, and particularly in the powerful mud in when dehydration under the pressure effect, this friction is just as one file, ceaselessly carry out rasion, greatly reduce the durability and the practicality of device.
2, since spiral shaft vane be all the time prop up the rotating ring internal diameter a bit make circular motion, the two not only bears sizable frictional force jointly, rotating ring also bears sizable deformation force, therefore, can't be applied to the sewage treatment plant of large and medium-sized specification.
The utility model content
Above-mentioned defective at prior art, technical problem to be solved in the utility model is to improve the friction of rotating ring and spiral shaft vane, prolong its service life, propose a kind ofly not only to be fit to be applied to middle or small sewage treatment, and be fit to be applied to the solid-liquid separating machine of large-scale wastewater treatment plant.
In order to solve the problems of the technologies described above, the utility model proposes following technical scheme: a kind of solid-liquid separating machine, comprise and decide ring, rotating ring and helical axis, helical axis directly upwards is provided with staggered fixed ring and rotating ring, its innovative point is, be provided with the gap between fixed ring and the rotating ring, the rotating ring internal diameter is provided with flange.
As optimal technical scheme of the present utility model, preferably be provided with the groove bar on the blade external diameter of helical axis, and the notch of groove bar and flange engagement.
Another optimal technical scheme that the utility model proposes: preferably be provided with bar on the blade external diameter of helical axis, the bar on the blade external diameter drives flange, and then drives the rotating ring rotation.
As an optimal technical scheme more of the present utility model, the space size between the blade of above-mentioned helical axis is preferably constant or dwindle gradually to outlet by effluent stream inlet.
With respect to prior art, the utility model adopts a plurality of staggered decide ring, trimmer, rotating ring and helical axis do filter bodies, utilizes the continuous extruding of spiral shaft vane to mud, fast and efficiently a large amount of mud and moisture content is discharged in the filter body; In addition,, when helical axis is driven, will drive the rotating ring motion simultaneously, avoid the friction between rotating ring and the spiral shaft vane because the groove bar of spiral shaft vane and the flange of rotating ring are meshing with each other; Moreover, because the groove bar of spiral shaft vane and the flange of rotating ring be meshing with each other, overcome that spiral shaft vane is the defective of a bit making circular motion that props up the rotating ring internal diameter all the time in the prior art.Solid-liquid separating machine energy consumption of the present utility model is low, noise is little, friction, simple in structure, durability good, easy to operate, practical, high efficiency not only is fit to be applied to middle or small sewage treatment, and is fit to be applied to large-scale wastewater treatment plant.

Fig. 2 is the partial enlarged drawing (B is the local position of amplifying of body among Fig. 1) of the utility model body.
Fig. 3 is the A-A cutaway view of Fig. 2.
Wherein:
1 is rotating ring; 2 are fixed ring; 3 is trimmer; 4 is helical axis; 5 is the groove bar; 6 are the effluent stream inlet; 7 is the mud outlet; 8 are back pressure adjustment plate; 9 is motor; B is the local position of amplifying of body.
The specific embodiment
The utility model is described in further detail below with reference to drawings and Examples.
As Figure 1-3, the solid-liquid separating machine that the utility model one preferred embodiment proposes, mainly by encircle 2 surely, rotating ring 1, trimmer 3, helical axis 4, groove bar 5, effluent stream inlet 6, mud outlet 7, back pressure are adjusted plate 8, motor 9 is formed; Helical axis 4 is driven by motor 9; The footpath of helical axis 4 upwards is provided with a plurality ofly staggeredly encircles 2 and rotating ring 1 surely, encircle surely 2 and rotating ring 1 between be provided with the gap that makes rotating ring 1 activity; Above-mentionedly a plurality ofly staggeredly encircle 2 surely, trimmer 3, rotating ring 2 and helical axis 4 form the filter bodies, utilizes the continuous extruding of spiral shaft vane to mud, can fast and efficiently a large amount of mud and moisture content be discharged from filtering in the body.
As shown in Figure 1, the blade pitgh of helical axis 4 is diminishing by effluent stream inlet 6 to mud outlet 7 in the present embodiment.
As shown in Figure 3, at mud outlet 7 back pressure is housed and adjusts plate 8, be used to regulate mud outlet size; The spiral shaft vane external diameter is provided with the groove bar 5 (as shown in Figure 3) of three five equilibriums, correspondingly on rotating ring 1 internal diameter also is provided with three flanges.When helical axis 4 was inserted filter body center, the notch of groove bar 5 just in time inserted the rotating ring flange, and male and female are meshed.
When helical axis 4 is driven, drives rotating ring 1 simultaneously and make cycle rotation, therefore, when sewage enters filter during body from inflow entrance 6, mud wherein is pushed to mud outlet 7, and moisture content is wherein extruded the slit of deciding 1 of ring 2 and rotating ring fast, and last mud is discharged from mud outlet 7.Therebetween, because encircle 2 relative activities with 1 generation of rotating ring surely, the gap of filter body will can not stopped up.
