The utility model relates to a kind of air-floatation water purifier, especially a kind of transmission device of mud throwing spoon that is used for shallow-pool air floatation water purifier.
Background technology
The structure of state-of-the-art super-effect shallow pool air-floatation water purifier is as shown in Figure 1, 2 on the our times:
Fig. 1, in 2: treating pond 13, turret mount 14, swivel joint 15, connecting hose 16, cloth bucket 17, water distributor 18, revolution drives stepless speed changer 19, shield cap 20, cast aside mud spoon 21, protective shield 22, cast aside mud spoon chain guard 23, cast aside the mud spoon and drive stepless speed changer 24, runway Scraping device 25, push rod 26, hang barrel 27, clear water riser tube 28, push rod 29, walk guidance tape 30, hang barrel 31, arc beam 32, hang screw rod 33, back support roller 34, centering wheel 35, cast aside mud spoon roller frame 36, driving wheel 37, follow-up pulley 38, rotary barrel 39, water level control apparatus 40, regulation of level bucket 41, sludge bucket 42, cast aside mud spoon bearing support 43, mixing tube 44, form 45, railing 46, walk guidance tape hanging feet 47.
As shown in Figure 1, 2: the pond body of the treating pond 13 of water purifier (hereinafter to be referred as the pond body) is a circular discoid, and the upper limb outer ring has endless track, and the bottom is by the crosslinked pallet that constitutes of longitudinal and transverse gusset.For ease of transportation, the pond body generally is made as three or five (during major diameter), in erecting stage assembling splicing, only diameter very little (being generally below the 3.5m), just is made as integral body.Shown in Fig. 1,2 is three chip architectures.The primary structure and the principle of work of water purifier are as follows:
Sewage is promoted by lift pump, following end interface from mixing tube 45 enters, and the dissolved air water after reliever discharges microbubble then enters from mixing tube 45 lateral inclined tubes, and two strands of current are behind uniform mixing, through pipe core, swivel joint 15, connecting hose 16, enter in the water distributor 18 successively.There are several downcomers water distributor 18 belows.Each downcomer opening respectively has a throttle plate, by screw rod and handwheel separately, can distribute the aquifer yield of each downcomer and regulate.Cloth bucket 17 have with water distributor 18 on the corresponding arc of downcomer quantity cut off.Current-sharing grid respectively are equipped with at the rear (referring to see Fig. 1 with respect to sense of rotation) that each arc cuts off, and the place ahead isolates with partition panel and pond body.Be equipped with in the bottom of partition panel and sweep the mud rubber, and the solid shape impurity that can sink not floating sweeps in the precipitation bucket of bottom, pond, regularly open the evacuated tube valve and discharge.The riser tube 28 that four or two (minor diameter is during low discharge) are used to promote clear water is housed on the rotary barrel 40, and there is trapezoid-shaped openings the below of riser tube 28.Clear water after flotation body come-up is separated is by the inside and outside waterhead of rotary barrel 40, flow into riser tube 28 through trapezoid-shaped openings, enter again in the annular space between rotary barrel 40 and the regulation of level bucket 42, little part (about 20%～30%) enters air dissolving system as recirculation water through the reflux pump pressurization through return line, air is dissolved in pressure, the preparation dissolved air water; Most through the 42 top overflows of regulation of level bucket, discharge by the clear water pipe.Rotary barrel 40 inside and outside waterheads are formed naturally by fluid resistance.The effect of regulation of level bucket 42 is the elevation of water surface in the equalizing tank, casts aside the degree of depth that mud spoon 21 casts aside scum layer thereby regulate, and the water ratio that scum silica frost has been cast aside in control satisfies the requirement of pressure filter.Sealed rubber is equipped with in rotary barrel 40 bottoms, prevents external short circuit in the rotary barrel 40.Regulation of level bucket 42 is made up of fixing bucket, adjusting bucket, setting device etc.Regulating bucket can upper and lower adjustings height by setting device, and fixing bucket is welded on the base plate of pond, and fixing bucket is provided with sealing with regulating between the bucket, and setting device has manual and electronic two kinds of structures, and shown in Fig. 1 is manual.The center welding pipe core of sludge bucket 43, pipe core top assembling swivel joint 15.Outer rim is welded with the centering flange on the sludge bucket 43, is welded with sludge pipe between bucket body and the pipe core.Sludge bucket 43 is welded on the center of pond body.The both sides, outer end of turret mount 14 are equipped with driving wheel and follow-up pulley respectively, all are bearing on the endless track of pond body upper limb, inner then by back support roller supporting 35 on plane on the centering flange of sludge bucket 43 upper limbs, realize 3 stable position.Cloth bucket 17, water distributor 18, rotary barrel 40 all are suspended in the below of turret mount 14 by suspender member, with casting aside mud spoon 21, constitute turning unit jointly.Driving wheel on the turret mount 14 drives rotation by stepless speed changer 19, by and runway between the counter-force of frictional force produce the power that makes the turning unit rotation.Also be provided with four centering wheels on the turret mount 14, they are along the centering to turning unit of the centering flange cylindrical scrolling realization of sludge bucket 43 upper limbs.Centering wheel is actual only to need two, and being provided with four is in order to prevent the drive-motor mis-wired, turning unit counter-rotating and having an accident.Left-falling stroke mud spoon 21 is made of the blade of two leaves or three leaf frustums, and an end is equipped with the mud pipe, and each blade all has casts aside helix angle.The outer end of casting aside mud spoon 21 is bearing in by spindle nose on the bearing support 44 that is fixed on the turret mount 14, and the other end then is bearing on two rollers of roller frame 37 of the left-falling stroke mud spoon 21 that is fixed on the swivel mount by the raceway circle.Cast aside mud spoon 21 and drive rotation (shown in Fig. 1 is chain drive) by the stepless speed changer 24 that is fixed on the turret mount 14, each blade is periodically cast aside into scum layer, and the scum silica frost of having cast aside (mud) utilizes gravity to flow in the sludge bucket through the mud pipe that falls, and is discharged by sludge pipe.The water purifier complete installation is on the roof beam structure of " well " font.According to handling water yield size, regulate the angular velocity of rotation of turning unit by stepless speed changer 19, the correct simultaneously water yield of adjusting each downcomer on the water distributor 18 is distributed, can make from current-sharing grid each point from the rolling tangential speed (velocity of following) of cloth bucket 17 effusive flow velocities (speed of relative movement) and corresponding points cloth bucket 17 (direction is opposite) about equally, according to kinematic principle, the absolute velocity of current will be zero substantially, and water body is with basic transfixion in the pond! Here it is so-called " zero velocity principle ".
At present, the type of drive of home and abroad super-effect shallow pool air-floatation water purifier left-falling stroke mud spoon mainly contains two kinds.
First kind is chain drive, as Fig. 1,2.There is following shortcoming in chain drive: 1, casting aside the mud spoon is to cast aside mud off and on.When a blade was cast aside the sludge blanket of the water surface in the treating pond, resistance produced immediately and increases rapidly, and along with the rotation of casting aside the mud spoon, blade breaks away from sludge blanket gradually then, and resistance disappears, and therefore, need bear periodic shock load when casting aside the work of mud spoon.The water purifier specification is big more, and shock load is big more.Have a left-falling stroke to go into helix angle though cast aside the blade of mud spoon, can reduce the peak value of shock load to a certain extent, shock load still exists, and bigger.Shock load can make driving chain that shake tempestuously, the galloping that causes casting aside the mud spoon take place.The water purifier specification is big more, because driving chain long more (referring to accompanying drawing 1), evil is gone through in shake more, and the stationarity of casting aside the running of mud spoon is poor more.Engineering practice proves that when left-falling stroke mud spoon structure was two leaves, situation was serious all the more.2, just owing to need bear bigger impact moving load, and often lack lubricated reliably, sprocket wheel particularly work-ing life of chain short.3, the line service amount is big.The one, need often to refuel, the 2nd, need adjust the tensioning degree of chain termly.Some users do not establish the special messenger and keep an eye on water purifier, and this shortcoming can be brought problem, cause the failure rate of water purifier to improve.4, transmission efficiency is low, has increased energy consumption.
Second kind is the shaft coupling integral drive, and structure is seen Fig. 3.Among Fig. 3: cast aside mud spoon 21, cast aside mud spoon spindle nose 49, bearing support 50, shaft coupling 51, variable-speed motor 52, frame 53.
Cast aside the mud spoon and be bearing on the bearing support that is fixed on the turret mount (in debug axle hold) by spindle nose, link by shaft coupling and variable-speed motor output shaft, variable-speed motor then is fixed on the frame that is welded in the turret mount outer end.The disadvantage of this type of drive is outer stretching in outside the turret mount, has occupied partly expensive real estate of original just not wide aisle, and obstruction is gone away, and more has potential safety hazard.So, whether can inwardly install, make variable-speed motor not overhanging? conclusion negates.If sleeve mechanism is inwardly moved, certainly will reduce to cast aside effective working length of mud spoon significantly, the α value among the figure is increased greatly, will have a great circle mud near the group of pond can not be cast aside, with the passing of time putrid and deteriorated.
It may be noted that since treating pond can not make absolute rounding, suitable α value is essential, but can not be excessive.Cast aside the mud blade and have certain helix angle owing to cast aside the mud spoon, when blade is cast aside into sludge blanket, can drive sludge blanket and do a certain amount of motion,, can fully eliminate mud accumulating in the α gap if the α value is not excessive to the center, pond; If the α value is excessive, then can not (mud mainly be that bonding force by mud itself drags to the motion at center in the α gap, and this bonding force is very little).
Also there is another shortcoming that can not be ignored in this type of drive: install to adjust and to have relatively high expectations, must be regularly or irregularly compensate adjusting, and regulate and have relatively high expectations, unskilled persons is difficult to be competent at.Because casting aside the inner of mud spoon is to be bearing on two rollers of roller frame that are fixed on the rotary barrel by the support roller raceway circle on the mud pipe that falls, rotary barrel is hung again on turret mount, therefore, and on the one hand, rotary barrel is hung and is highly directly had influence on the setting angle of casting aside the mud spoon, and higher requirement is arranged; On the other hand, be in operation,, cast aside mud spoon shaft center line angular variation can take place gradually along with the wearing and tearing gradually of back support roller, centering wheel and left-falling stroke mud spoon support roller.
Setting angle deviation and the angular variation that will take place from now on all can be reflected on the shaft coupling.Consider the reason of buffering and scantlings of the structure, shaft coupling generally adopts elastomer block or spring pin shaft coupling.This shaft coupling can only be tolerated small diaxon relativity shift.Although setting angle error and the angular variation that will take place from now on, it is reduced all can to sentence sizable ratio at shaft coupling, but still needs strict restriction.If the setting angle error is excessive, perhaps the angular variation that will take place from now on will be excessive in time regulates, and perhaps regulates incorrectly, all can cause variable-speed motor, bearing support neck bearing and shaft coupling to bear very big additional load, increases energy consumption, shortens the life-span, even damages.
