Abstract
The present invention provides a subaqueous stirrer which can inhibit the attenuation of water discharged out of a discharge opening and can really stir objects within a large range. When a rotation driving mechanism rotates impellers in a pump casing, water is sucked into the pump casing and flows through the pump casing in the axial direction; then, the water is led in and discharged out of the casing, and is discharges out of a plurality of discharge openings which are divided in the circumferential direction from each bulkhead member. The discharged water is divided by each bulkhead member, and water beams are respectively formed so that the water flows in an unattenuated mode within a large range. When discharged out of the discharge openings, the water flows through guiding ditches formed by each bulkhead member on each bulkhead part, and the water discharged out of each of the discharge openings forms wakes.
Description
The present invention relates to mixing plant in the water, it is arranged on down in the water such as water, by attracting sewage and sewage such as water being stirred down in its discharge.
Usually, to sewage etc. stir and carry out qi of chong channel ascending adversely mixing plant in the water of qi of chong channel ascending adversely, as Japanese patent laid-open 6-285488 number etc. disclosed, drive an impeller that is configured in the pump case cylindraceous by revolutions such as motors in the water, just can be attracted to water in the pump case.Water in attracteding to pump case can make the air diffusion of supplying with by method for distinguishing in the water that attracted in the pump case in the flow process with connecting in the pump case, then can with through the water of air diffusion along full week of pump case, discharge towards the radiation direction.

Be configured on the downside axle center part on the hub portion 21 of the impeller 20 in the pump case 30 and plugging air supply pipe 50.Circumferential sky is disposing a plurality of air outlet 21b with opening equal intervals in side face upper edge, the top of hub portion 21, and the air that provides from air supply pipe 50 is discharged in the outer cover body 31 of pump case 30 by each air outlet 21b.
Fig. 3 is the part of discharge shell 40 that fits over the upside of pump case 30 plan view of deciding what is right and what is wrong, and Fig. 4 is the AA line profile along Fig. 3.As shown in Figure 4, this is discharged shell 40 and has central part the last guide plate 43 that the circular following guide plate 42 of peristome 42a and sky are configured in the top relative with this time guide plate 42 is being set with opening appropriate intervals.
Following guide plate 42 stretches out to foreign side to oblique below obliquely with the angle about the 5-40 degree around the peristome 42a that is arranged on axle center part, and the inner peripheral portion around the peristome 42a bends to circular-arc downwards.And in the inner peripheral portion of following guide plate 42, be provided with along the flange part 44 above the outer cover body 31 that is placed on pump case 30 full week.This flange part 44 by bolton on the outer cover body 31 of pump case 30.
As shown in Figure 3, last guide plate 43 is by member 46 6 five equilibriums along the next door that the radiation direction is extended on the six circumferential position of halving.This cuts apart number also can be according to the different and suitably change of machine.Each next door member 46 has roughly along the radiation direction, at a pair of wall part 46a that extends between guide plate 42 and the last guide plate 43 down.Each wall part 46a is that ground is crooked downwards to be constituted by being integral with last guide plate 43, and lower lip forms the state of colliding above with guide plate 42.
Interior all sides of next door member 46 partly form the connecting portion 46b that the interior all sides with each wall part 46a partly are connected to each other.This connecting portion 46b inwardly week side-prominent ground, become circular-arc with bigger curvature bending, and along be positioned at the heeling condition that ground, top becomes 30-60 degree degree toward interior all side directions.
Form the guiding ditch of opening with foreign side upward, edge radiation direction is extended 45 between each wall part 46a.
The part that is surrounded by the wall part 46a of each next door member 46 and following guide plate 42 and last guide plate 43 forms the outlet opening 41 that can be made the water that water flows through upward with connecting by impeller 20 respectively.
Each wall part 46a is along with forming the open state in ground that is separated from each other successively toward outer circumferential side, therefore, the guiding ditch 45 that forms between each wall part 46a makes the width of cloth increase to size along with the outer circumferential side of guide plate 42 down.Consequently, by the outlet opening 41 of the side's respectively of the next door member 46 of adjacency wall part 46a regulation along with forming the state that circumferentially narrows down successively toward separately outer circumferential side.
The sweep upper support of the interior all sides on last guide plate 43 the following ora terminalis of the support member 48 that is circular cone shape.This support member 48 forms the state concentric with the through hole 43a of last guide plate 43, and the ground connection side face that links to each other with the connecting portion 46b of each next door member 46 becomes 45 inclinations of spending degree.The open shape of the top and following formation of support member 48, motor 11 and reductor 12 connect into the output shaft extension state downwards vertically that makes it in the water of rotary motion mechanism 10, and the reductor 12 that is connected with motor 11 in the water is positioned at the through hole 43a of support member 48 and last guide plate 43.
Above the guide plate 43 of a side position of the guiding ditch 45 that sets, form hook member 49 respectively to 1 position, interval in all guiding ditches 45.On each hook member 49, fastening the bottom of boom hoisting 60 as depicted in figs. 1 and 2, on this boom hoisting 60, fastening wire rope etc., be installed on its bottom surface after qi of chong channel ascending adversely mixing plant in the whole water being dropped to inside such as treatment reaction groove.
When having qi of chong channel ascending adversely mixing plant in the water of this structure when being installed on the bottom surface of treatment reaction groove etc., drive motor 11 in the water of rotary motion mechanism 10, make impellers 20 revolutions in the outer cover body portion 31 that is configured in pump case 30 thus.By the revolution of leaf impeller 20, water is attracted to by the bottom surface in the outer cover body 31 of pump case 30, connect in the outer cover body 31 and flow upward.
At this moment, the air of supplying with from air supply pipe 50 is discharged from from each air outlet 21b on the top side face that is arranged on hub portion 21.And the air of discharging from each air outlet 21b is blended in by diffusion in the water that outer cover body 31 ground that connect pump case 30 flows upward.Because each air outlet 21b and impeller blade 22 turn rounds coaxially, thereby cut off by gyroscopic action finely, form trickle bubble, thereby the interior oxygen of bubble is dissolved in the water effectively from the air of each air outlet 21b discharge.
Like this, ground flows upward in the outer cover body 31 of the water perforation pump case 30 that trickle bubble spread, be directed between the following guide plate 42 and last guide plate 43 of discharging shell 40, along radiating direction bending laterally, be directed downwards tiltedly injection along radiation by last guide plate 43 effects from each next door member 46 all outlet openings 41 at interval.
Because the water of discharging from all outlet openings 41 flows along the bottom of treatment reaction groove etc., thereby the water at the place, bottom of treatment reaction groove etc. can positively be stirred.Again because the water of discharging from outlet opening 41 is mixed with air effectively, thereby the bottom of treatment reaction groove etc. can be by qi of chong channel ascending adversely effectively really.
Because each outlet opening 41 forms by next door member 46 state at interval, and along with toward outer circumferential side and at the state that circumferentially narrows down, thereby discharge the current that form bundle from each outlet opening 41.Its result, owing to suppressed the dispersion of the current of discharging from each outlet opening 41, thereby attenuation diminishes, can reach changes at a distance.
Because the guiding ditch 45 open with foreign side is being set between each outlet opening 41 upward, thereby current are when each outlet opening 41 is discharged, and water on every side flows along each guiding ditch 45.Owing to each bar guiding ditch 45 is the states that broaden along with toward outer circumferential side, thereby flow sleekly to the radiation direction with the water of discharging from each outlet opening 41 by the water of guiding ditch 45, formation wake in toll bar vortex ground does not take place at each side edge parts of the current of discharging from each outlet opening 41.Its result, the current of discharging from outlet opening 41 can not be subjected to encumbering of toll bar vortex, and form significantly current, therefore the bottom that can positively stir the treatment reaction groove at wider range.
Because flowing into the water of discharging in the shell 40 is cut apart in each outlet opening 41 sleekly by the circular-arc connecting portion 46b in the next door member 46.And circular-arc connecting portion 46b prevents to sneak into the field trash in flowing into the water of discharging in the shell 40, and residue etc. are wrapped on the next door member 46.Thereby water can discharge sleekly from each outlet opening 41, and motor 11 etc. can not produce overload in impeller 20 and the water.
Also have a pair of wall part 46a, thereby form the state that whole discharge housing 40 is enhanced, the intensity of discharging housing 40 is improved significantly by each wall part 46a owing to next door member 46.
The structure of the foregoing description is to be installed in the upside of pump case 30 discharging shell 40, but the present invention also can make and be installed in the downside of pump case 30 with discharging shell 40, attracts water and is discharged from downside from the upside of pump case 30.
Like this, because mixing plant is will discharge shell by the next door member to be divided into a plurality of outlet openings in the water of the present invention, thereby discharge from each outlet opening on current bunchy ground.Its result has suppressed from the decay of the current of each outlet opening discharge, and each current can stir water in more vast zone.Again because a pair of wall part of each next door member forms open with foreign side upward guiding ditch, in the current of discharging, produce wake by the guiding ditch by each outlet opening, so can eliminate the decay of the current of discharging from each outlet opening that cause by the toll bar vortex, can improve mixing power by the effect of wake.
By forming the structure of the current of discharging from outlet opening being brought together bunchy by the wall part separately of each next door member, further suppress current decay, can stir water more widely.
Also owing to partly be connected to each other with the interior all sides that inwardly become circular-arc outstanding connecting portion with the wall part separately of each next door member, thereby can prevent that residue, field trash etc. in the divided water of each outlet opening are wrapped on each next door member, can unimpededly discharge water.
Owing to added the qi of chong channel ascending adversely function that makes the water that air diffusion is discharged from, thereby can carry out qi of chong channel ascending adversely at wider range and handle.
