Describe the present invention below in conjunction with accompanying drawing.
As seen from Figure 3, this inclined-plate clarifying basin comprises the outer cylinder body 7 that is provided with water inlet, be positioned at the swash plate group 15 of outer cylinder body, be positioned at the mud collection area 9 of outer cylinder body bottom, it is characterized in that this inclined-plate clarifying basin also comprises the power transmission shaft that is positioned at outer cylinder body 7 centers and fixedlys connected with swash plate group 15 outlet pipe 8 of holding concurrently, with this power transmission shaft drive disk assembly 1 that outlet pipe 8 links to each other of holding concurrently, connect the hold concurrently parts that catchment of outlet pipe 8 of swash plate group 15 and power transmission shaft.Wherein drive disk assembly 1 is motor and the worm gear speed changer that is connected with motor.Swash plate group 15 axially superposes a plurality of reverse frustoconic swash plates, and the space is left between two layers of swash plate in rounding platform inclination angle about 30 °, and concrete size requires to set according to difference, is generally 30～50mm.Power transmission shaft is held concurrently between outlet pipe 8 and the rounding platform swash plate group 15 and to be connected by rotating frame 14, and every rounding platform swash plate all is nested on the rotating frame 14, and makes relative fixed, and then is fixed on power transmission shaft and holds concurrently on the outlet pipe 8.The parts that catchment comprise that the clear water that is arranged on the every nearly lower edge in the swash plate back side among the swash plate group 15 collects box 16, and connect clear water and collect the hold concurrently flexible pipe 17 of outlet pipe 8 of box 16 and power transmission shaft.2～4 clear water can equidistantly be housed near the every swash plate back side lower edge collect box 16, power transmission shaft distribution clear water water outlet tubule 2～4 rows on the tube wall of outlet pipe 8 that hold concurrently, the a plurality of tubules of every row, corresponding with a plurality of rounding platform swash plates, thus it is corresponding with a clear water water outlet tubule to make each clear water collect box.Be provided with circular arc inlet damper 13 near the water inlet between outer cylinder body 7 and rounding platform swash plate group 15, its height is identical with rounding platform swash plate group 15 height.Be provided with discharge pipeline 11 and mud valve 10 between the mud collection area 9 and the external world.Power transmission shaft outlet pipe 8 tops of holding concurrently are provided with clear water overfall 6, and clear water overfall 6 peripheries are with clear water surge drum 5, are provided with treated water conduit 3 between the clear water surge drum 5 and the external world.In outer cylinder body 7, also has the dividing plate 18 between swash plate group 15 and mud collection area 9.
Former water enters outer cylinder body 7 by water intaking valve 12, under the water conservancy diversion of inlet damper 13, former water tangentially distributes handle to enter rounding platform swash plate group 15 upper limb, drive disk assembly 1 drives power transmission shaft outlet pipe 8 rotations of holding concurrently, connection effect by rotating frame 14, rounding platform swash plate group 15 also rotates together, at gravity, and centrifugal force, under the centripetal force multiple action, mud glides and trend cylindrical shell central authorities along swash plate, sinks to the mud collection area 9 of cylindrical shell bottom along swash plate group 15 lower edges, discharges through discharge pipeline 11 and mud valve 10, because the effect of dividing plate 18, water body remains static around here, helps the sedimentation of mud, so the thickening effect of mud is fine.Along with continuous deposition and the downslide of mud on the swash plate face, upper strata water quality obtains clarification between plate, water quality the best of it should be positioned at close lower edge exit, upper strata between plate, the clear water that is provided with at this place is collected box 16 and by flexible pipe 17 clear water of collecting is flowed into the power transmission shaft outlet pipe 8 of holding concurrently, when water level rises to clear water overfall 6 in the pipe, excessive to clear water surge drum 5, effluent trough 2 backs that arrive cylindrical shell 7 outsides by treated water conduit 3 are discharged by clear water pipe 4.
By among Fig. 4 as can be seen, under the effect of inlet damper 13, former water is tangential direction when entering swash plate, adds the rotation of inclined board, makes the swash plate group go up every bit and can both hold equably and receive into water.This structure can improve the uniform distribution degree of water inlet, has simplified water distribution process and facility again.
By among Fig. 5 as can be seen, under the effects that swash plate 20 evenly rotates, current form the tangential screw line, have increased current and the stroke of wadding grain between swash plate, make the growth of rolling under the double action of gravity and tangential force of wadding grain.Thus, the comparable concurrent swash plate of swash plate length is short, and like this, device miniaturization has just had may.
By among Fig. 6 as can be seen, except the gravity effect, add the effect of rotary centrifugal force, make the wadding grain move rapidly to 20 of swash plates, accelerated separation process, guarantee the formation of plate upper strata clear water zone.
By among Fig. 7 as can be seen, the current under the rotation status, the linear velocity of its outer ring is big, so can form center low-pressure area 19, i.e. forced vortex can impel mud to concentrate to pivot, helps the collection and the eliminating of mud.
As seen from Figure 8, when swash plate remains static, current between two layers of swash plate 20 are in laminar condition, velocity flow profile is very inhomogeneous on the cross-section of river, be parabola state, high-flow area in the middle of last fleece grain will pass just can enter lower sediment, and this high speed impact is very unfavorable to precipitation.Yet, after the swash plate rotation, eliminated near the almost nil state of flow velocity of swash plate, making into, the flow velocity of water section is tending towards even, can reduce the influence that current are subjected to density contrast and temperature difference, improve the area utilization and the stability of pond body, more help the carrying out precipitated and the raising of aquifer yield.
As seen from Figure 9, energy of rotation diminishes the inclination angle of swash plate 20, thereby the precipitation projected area is strengthened, and deposition efficiency is higher, generally can improve two times., under the swash plate inactive state, glide smoothly in order to make mud in the past, and prevented the mud accumulation, the inclination angle of swash plate need be not less than 60 °, and under the swash plate rotation status, mud is difficult for piling up, and the inclination angle can be designed to smaller or equal to 30 °.
As seen from Figure 10, clear water collect to adopt the clear water that is positioned at the swash plate lower rear to collect box, and its advantage is: prevent that mud from taking out of downstream 1..2. this box is in rotation status, can draw the clear water that is in relative static conditions equably, because suction is not to be fixed on a place, can avoid disturbance sink mud, the raising effluent quality.3. exit branch can directly closely be connected with outfall sewer by flexible pipe, and this is much more superior than catchmenting of concurrent swash plate in the past.
As seen from Figure 11, mud 22 directly slips into the sludge settling district from rounding platform swash plate group's lower edge and the power transmission shaft circular passage that outlet pipe forms of holding concurrently, because the effect of dividing plate 18, water body remains static around here, the precipitation 21 that helps mud is so the thickening effect of mud is fine.
