Technical field
The present invention relates to solid-liquid separation technique, belong to the filter in environment protection sewage field especially.
Background technology
Chinese invention 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 the foregoing invention 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.
Summary of the invention
Above-mentioned defective at prior art, technical problem to be solved by this invention 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 screw type solid-liquid separating machine of large-scale wastewater treatment plant.
In order to solve the problems of the technologies described above, the present invention proposes following technical scheme: a kind of screw type solid-liquid separating machine comprises and decides ring, rotating ring and helical axis that helical axis directly upwards is provided with staggered fixed ring and rotating ring, it is characterized in that rotating ring is connected with guide rod; Guide rod is connected with connecting rod; The helical axis two ends are provided with eccentric segment, and connecting rod is socketed in eccentric segment; Helical axis drives the eccentric segment rotation, and then drivening rod is made eccentric motion; The eccentric motion of connecting rod drives guide rod moving linearly in guide rail, and then orders about the rotating ring motion.
Preferably, above-mentioned rotating ring of the present invention and fixed ring are equipped with opening.
Preferably, eccentric segment of the present invention and helical axis are one-body molded.
Preferably, eccentric segment of the present invention is the eccentric bushing that is socketed on the helical axis.
Preferably, rotating ring of the present invention is connected with two guide rods, and two guide rods are 180 degree and are symmetrical arranged.
With respect to prior art, the present invention adopts a plurality of staggered decide ring, rotating ring, trimmer and helical axis do filter bodies, utilize spiral shaft vane that mud is constantly advanced, pushes, fast and efficiently a large amount of mud are outwards separated, discharge in the filter body with moisture content.The motion that the present invention filters the body rotating ring is the motion that eccentric motion produced by eccentric segment drivening rod and guide rod, so, so just fundamentally solve the wear problem between rotating ring and the spiral shaft vane, improved the durability and the practicality of separator greatly.Energy consumption of the present invention is low, friction, and noiseless is suitable for large, medium and small type sewage-farm.
