On axis body 11, at each sidepiece of its length direction, forming respectively near 11 the central portion along orthogonal each slot part of the diametric(al) of axis body 11 from each end face to axis body, stirring vane 12 at each slot part internal support.Each stirring vane 12 inserts respectively in each groove with the central portion and the orthogonal mode of the length direction that clips axis body 11 of separately long leg 12a, and is being supported with the state that the vertical bisecting line of each long leg 12a runs through the axle center of axis body 11.The 12c of front end edge portion of stirring vane 12 is respectively from the outstanding suitable length of the end face of axis body 11.
On axis body 11, be provided with the bearing portion 13 that connects the hollow of axis body 11 with the state vertical respectively in the substantial middle portion of each stirring vane 12 with stirring vane 12.
In each bearing portion 13, insert bolster 16 respectively.Each bolster 16 with its end separately from the outstanding state of bearing portion 13, be installed in each bearing portion 13 integratedly.The end of each bolster 16 is being supported with the state between each 15a of pole portion leading section of the connecting elements 15 that is erected at respectively the V word shape that is made of a pair of pole 15a of portion.
Aforesaid stirring body 10 is driven by drive division 20, and axis body 11 is that the center is shaken on one side around its axle center rotation with the central portion of length direction on one side.As shown in Figure 1, drive division 20 have across a pair of support plate 21 that appropriate intervals is configured in parallel to each other and 22 and between two support plates 21 and 22 with support plate 21 and 22 uniformly-spaced and the stator support plate 23 that disposes abreast with support plate 21 and 22.Each support plate 21 is connected by connecting axle 24 each other with 22 its each relative bights, and in addition, each bight of stator support plate 23 is bearing in the central portion of connecting axle 24 respectively.
On stator support plate 23, form a pair of through hole 23a respectively, in the outer peripheral edges portion of each through hole 23a, forming step respectively.The stator 25 that constitutes motor is installed respectively on each step 23a.In each stator 25, be provided with along uniformly-spaced also inwardly square 12 the outstanding stator core 25a of circumferentially spaced, on each stator core 25a, be wound with coil 25b respectively.
Central portion at each stator 25 is provided with rotor 26 respectively.Each rotor 26 have with the rotating shaft 26a of stator 25 concentric configurations.Each end of each rotating shaft 26a is rotatably mounted by the bearing 27 that is arranged on support plate 21 and 22 respectively.At the axial central portion of the rotating shaft 26a of each rotor 26 respectively to be provided with the external diameter plectane portion 26b bigger than the external diameter of rotating shaft 26a with the concentric state of rotating shaft 26a.Each 26b of plectane portion disposes respectively in each stator core 25a of stator 25, and is other along not being provided with high magnetic flux magnet 26c full week in the outer peripheral edge portion of each 26b of plectane portion.
Respectively the torque that each motor had that constitutes by stator 25 and rotor 26 be directly proportional by the width (length of radial direction) of the magnetic density that is installed in the high magnetic flux magnetite 26c in the rotor 26 respectively and each high magnetic flux magnetite 26c and the magnetic field intensity of thickness decision.The repulsion that is directly proportional with the magnitude of current that flows through in the coil 25b on the stator core 25a of each stator 25 respectively becomes torque.Therefore, be installed in the width of the high magnetic flux magnet 26c on each rotor 26 or increase the density that is located at the coil 25b on the stator 25, can improve the repulsion to each stator 25 of each rotor 26, the torque that can improve each rotor 26 respectively by increase.
The end of the rotating shaft 26a of each rotor 26 is outstanding from a support plate 21 respectively, in the end of the rotating shaft 26a that gives prominence to from support plate 21 star coupling 28 that rotates integratedly with each rotating shaft 26a is installed respectively.
Each universal coupling 28 is connected with the joint portion of a pair of pole 15a of portion of each connecting elements 15 of above-mentioned stirring body 10, therefore, the axis body 11 of stirring body 10 is installed on the drive division 20 with the states of relative rotation axi 26a inclination 45 degree and with the state that can shake rotation.
Each connecting elements 15 is installed on the universal coupling 28 in shaking under the state that central shaft 15b makes phase shifting 90 degree separately mutual vertically separately.
The other end of each rotor 26 promptly is equipped with electromagnetic type starting drive 29 respectively on the opposite end in the end that is connected with universal coupling 28.Each starting drive 29 has solenoid 29a respectively, on the leading section of the plunger 29b of each solenoid 29a columned tumbler 29c is installed, and this tumbler 29c rotates rotating shaft 26a by combining with rotating shaft 26a in 45~90 degree scopes.
Revolving meber 29c is arranged on the plunger 29b, and sliding along direction of principal axis by plunger 29b rotates rotating part 29c on one side to the edge prescribed direction of sliding in the same way.In addition, revolving meber 29c is bearing in the supporter 29d that is located between solenoid 29a and the support plate 22, is provided with spiral helicine groove on the outer peripheral face of rotating part 29c, rotatably disposes many ball 29e in its groove.Therefore, revolving meber 29c is by many ball 29e supporter 29d revolution and being supported slidably relatively.
Be provided with compression spring 29f between revolving meber 29c and support plate 22, solenoid 29a energising made plunger 29b when sliding with the approaching direction of support plate 22, the elastic force pressure that revolving meber 29c then revolts compression spring 29f combines with rotating shaft 26a.Under this state,, make rotating shaft 26a with prescribed direction rotation 45 to 90 degree because rotating part 29c rotates along prescribed direction.In contrast, when stopping solenoid 29a switched on, because the bounce of compression spring 29f, revolving meber 29c slides to solenoid 29a side, removes combining of revolving meber 29c and rotating shaft 26a.
Each starting drive 29 is when each rotating shaft 26a of difference rotary driving part 20, and to solenoid 29a energising, the revolving meber 29c that is located at plunger 29b tip combines with rotating shaft 26a respectively, and each rotating shaft 26a is rotated in the angles with 45 to 90 degree respectively.Thus, each rotating shaft 26a obtains the starting torque of about 100kgfm respectively, successfully begins rotation.When rotating shaft 26a began to rotate, thereafter, rotating shaft 26 was by 1/3rd to 1/5th torque actuated rotation of the torque in when starting.
Be arranged at each rotating shaft 26a on each rotor 26 respectively when starting once more when initial startup and after breaking down, need very big torque.At this moment, switch on by the solenoid 29a short time to each starting drive 29, rotating shaft 26a is rotated by high torque (HT) the plunger 29b of each solenoid 29a by start moment respectively.
General motor uses geared motor to make the rotor rotation when starting and obtains very high torque, in this case, needs a lot of electric power of consumption.In contrast, use starting drive, only need give the electric current that solenoid 29a passes to the short time, can make rotating shaft 26a rotation, can reduce energy consumption significantly with solenoid 29a.
In above-described agitating device, in drive division 20, each rotor 26 that constitutes motor is respectively with opposite direction running.At this moment, one of them rotor 26 is to be higher than the benchmark rotary speed rotation of regulation, and at that time, another rotor 26 is to be lower than its benchmark rotary speed rotation.Such as, each rotor 26 every rotation pi/2 (phase place), then rotor 26 run up and low-speed running carries out alternate with each other.
Fig. 5 is the time diagram of the rotation of each rotor 26 under this situation of expression.The x axle is represented the phase place of each rotor 26, and the y axle is represented the rotary speed of each rotor 26.SO on the y axle is the benchmark rotary speed of each rotor 26, and the rotary speed of each rotor 26 is represented by chain-dotted line and double dot dash line respectively.The position sensor of expression position of rotation is installed respectively on each rotor 26.(not shown)
Fig. 6 is the time chart of each rotor 26 during with high speed SH and low speed SL alternate-running.The mean value of high-speed SH and low velocity SL is benchmark rotary speed SO.Each rotor 26 is every rotation pi/2 (phase place) respectively, and alternate repetition carries out certain high speed rotation SH and the low speed rotation SL that relative datum rotary speed SO has equal rotary speed difference respectively.Promptly carry out high speed when rotating SH when a rotor 26,26 of another rotors carry out low speed rotation SL.And, each rotor 26 every rotated pi/2 (90 degree) after, the rotary speed of each rotor 26 switches to respectively at a high speed and low speed mutually.
As mentioned above, the rotation of the rotating shaft 26a by controlling each rotor 26 can make the angular velocity of rotation of the axis body 11 of stirring body 10 can homogenising.Perhaps also can control each rotor 26 rotating shaft 26a torque and for certain, reach the purpose of homogenization of angular velocity of rotation of the axis body 11 of stirring body 10.
By making each rotor 26 alternately carry out high speed and low-speed running repeatedly, the axis body 11 of the stirring body 10 that is connected with rotating shaft 26a respectively by universal coupling 28 revolves around its axle center and turn 90 degrees (=pi/2), and the incline direction of axis body 11 also changes 90 degree simultaneously.Therefore, shake from top to bottom at a stirring vane 12, and meanwhile during rotating pi/2 phase around the axis body 11, Yi Bian shaking from bottom to top, 12 one side of the opposing party's stirring vane around axis body 11, rotate pi/2 phase.And, carry out such action successively repeatedly by stirring body 10, cause each stirring vane 12 to carry out rotatablely moving of intermittence.
Stirring body 10 is arranged in the fluid that need stir or mix.Such as, for the water in the tank is flowed, stirring body 10 is set in water, alternately turn round with the cycle high speed and the low speed of regulation respectively at each rotor 26 drive division 20, axis body 11 every rotations the pi/2 cycle, 12 of each stirring vanes of stirring body 10 shake action repeatedly.Therefore, the stirring vane 12 that shakes action and high speed and low speed alternate-running repeatedly promotes water when it rotates, form current.
Under above situation, the resistance that gives stirring vane 12 as the water of fluid is very little, the electric power that stirring vane 12 rotation is consumed does not obtain the required electric power height of same mixing effect in the time of can be than the stirring body that uses three-dimensional shape, not equal to its power consumption reduces.
Therefore, we think, such as working as fluid is under the situation of water, by making the stirring vane 12 that is respectively plate be rotated motion off and on while shaking, water is in turn flowed into by each stirring vane 12 released and in the space that produces, the water of inflow forms the group of little eddy current, and, replace little eddy current continually, the frictional resistance of the boundary of the water of inflow and the water that stops significantly to reduce.Even the end of a thread that generally is easy on the stirring vane also is not easy to be inhaled near the rotary area of stirring vane 12.Its result, the reason that is considered to be used to make the energy consumption of stirring vane 12 rotations to reduce.
As mentioned above, while when releasing water, form a main current band by the water of releasing stirring vane 12 being shaken be rotated off and on motion.The deflection angle (the basin width of cloth) in relative its axle center of this main current band is little, becomes the narrow high flow rate of the dispersion of distribution of flow velocity.Its result can make the main current that produced by each stirring vane 12 take to respectively and reach a distant place.
In contrast, in the stirring vane of three-dimensional shapes such as screw, its volume is big more, and the main current band of the generation relatively deflection angle (the basin width of cloth) in its axle center is big more, and simultaneously, rotary speed is fast more, forms flowing of fierceness that the self-gravitation effect produced around blade.As a result, on the stirring vane of three-dimensional shape, apply very big resistance, give water very big propulsive force by three-dimensional stirring vane.But in the case, the basin width of the current of release is very wide, the main current of formation is taken to reach a distant place.
As mentioned above, each rotor 26 is by carrying out same high speed rotation and low speed rotation respectively repeatedly, and each stirring vane 12 of stirring body 10 promotes water with same strength respectively, forms main current.But, promoting water by only utilizing a slice stirring vane 12 wherein, it is minimum that another sheet stirring vane 12 generation water are released, and the basin width of the main water band that can form is narrower, main water is taken to reach a distant place.In the case, as shown in Figure 6, only need not set greatly the difference of the high speed of a rotor 26 rotation SH and low speed rotation SL and benchmark running speed, and with the difference that the high speed of another rotor is rotated SH and low speed rotation SL and benchmark rotary speed SO do not set little getting final product.
Using outer peripheral edge portion at each rotor 26 not to be provided with under the situation of drive division 20 of high magnetic flux magnet 26c, not only can use stirring body 10 with tabular stirring vane 12, can also use the stirring body 30 of three-dimensional shape as shown in Figure 7.The details of the stirring body 30 of this three-dimensional shape is recorded in " spy opens flat 11-276874 number " communique, be that flat each stirring vane 12 of stirring body shown in Figure 1 10 is expanded gradually along with the distant place side of the stirring vane 12 that becomes the opposing party, become mutual incorporate shape, promptly form the stirring body 30 of this three-dimensional shape.
Agitating device of the present invention is shaken while the axis body of stirring body is rotated back and forth by the rotation of the pair of rotary shafts that is arranged on drive division, arrives a distant place by a pair of stirring vane propelling fluid that is located on the stirring body.Therefore, can be with low electric energy consumption agitated liquid expeditiously.
In addition, the drive division driven rotary axle of agitating device of the present invention rotation, this drive division is provided with the high magnetic flux Magnmet rotor by its outer peripheral edges portion and stator constitutes, therefore, and its structure simple, thus make the maintenance of machinery very easy, and economy significantly improves.
