Description
Technical field
The present invention relates to a kind of non-homogeneous spraying and splashing facility.
Background technology
Water spreading disc is commonly used in daily life and industrial and agricultural production.Industrially, in power generating plant cooling tower using dabbling
Dish carries out uniform splash to recirculated water, and being exchanged heat in filler with cold air cools down；Agriculturally, commonly use water spreading disc and spray filling to soil
Irrigate, play a part of not only uniform irrigation but also energy-saving and water-saving；Some feed lots are entered also using water spreading disc sprinkling water smoke to animal simultaneously
Row cooling.
Currently used water spreading disc can only uniformly be sprayed water, and can not realize that a certain region is sprayed water less, and a certain region is sprayed water more.So
And to subregion, optionally non-homogeneous sprinkling has urgent demand in many fields now, such as power generating plant cooling tower often can
Because external environment condition effect of Side Wind, and the cooling effect in cooling tower is had an impact, it is necessary to which water spreading disc is according to cooling effect
Quality and the non-homogeneous water spray in subregion, the region of good effect of heat exchange need spray density big, effect difference region then need it is smaller
Spray density.During agricultural irrigation, as the factor such as different zones growing way is different, floristics difference is, it is necessary to subregion
Non-homogeneous water spray.
Current individual layer water spreading disc occur sprinkling region in have hollow space, this have impact on spray effect, in practice for
Solve hollow problem, the sprinkling region of water spreading disc can be piled up to make up hollow space.But this method, which can increase, to dabble
Dish quantity so that cost increase, service life decline.
The content of the invention
Present invention aims at：Receive pulse signal using micro-step motor to control the rotation of gear, so as to drive
The Semicircular baffle being connected with gear realizes in sprinkling zone optionally non-homogeneous water spray around the rotation of first layer water spreading disc.
Gone out by the splash current that baffle plate covers from the tilting bottom of baffle plate by potential energy impact second layer water spreading disc, again uniform splash
Go.The design of double-deck water spreading disc takes full advantage of current and its potential energy more than needed, and list is also reduced while increasing splash radius
Layer water spreading disc is in hollow region area caused by splash.
To achieve the above object, the present invention realizes by following technical solution：

Cross support 9 to fix, the outside of first layer water spreading disc 1 parcel baffle plate 7, the upper end of baffle plate 7 is fixedly connected with driven gear 13, driven gear
13 are arranged in connecting tube 10 by nylon bearing 8, and nylon bearing 8 is that interference fit connects with driven gear 13, connecting tube 10
Connect.The outer ring inner ring material of nylon bearing 8 is POM nylon plastic(s)s, and centre is glass steel ball.Driven gear 13 is nibbled with driving gear 6
Close, driving gear 6 connects a micro-step motor 3 by power transmission shaft 5, and micro-step motor 3 is fixed by electric machine support 12
In connecting tube 10, terminal box 4 is set on micro-step motor 3.
Micro-step motor 3 connects power supply come the operating of motor by terminal box 4, while receives and feedback control letter
Number.A fixed angle, i.e. stepping angle are rotated by the direction of setting after the return pulse signal of micro-step motor 3, according to arteries and veins
Quantity is rushed to control angular displacement, blocking angle and be accurately positioned non-homogeneous sputtering zone so as to reach by regulating fender 7
Purpose, has rapid starting/stopping, the characteristics of angle is accurate, while can be by the speed that controls pulse frequency to be rotated come controlled motor
And acceleration, reach the angle of quick regulating fender 7 to reach the purpose of designated area.The working condition of micro-step motor 3
There are continuously and smoothly's rotation, specified angle rotation, stop three kinds, when continuously and smoothly rotates, baffle plate 7 is continuous even in circumferential plane
Speed stops the current that the splash of first layer water spreading disc 1 goes out, in the range of the certain time from the point of view of, be actually accomplished that whole splash zone
The uniform splash in domain；When needing to a certain designated area splash, then provide pulse signal and revolved by stepper motor by specified angle
Turn, drive baffle plate 7 to shelter from stopping behind the non-sputtering zone specified.
The material of driving gear 6, driven gear 13 and baffle plate 7 is all polyether-ether-ketone（PEEK）, there is corrosion resistance, low noise
Sound, it is in light weight the characteristics of, the weight of part is also reduced while reducing cost, the diameter of driving gear 6 is less than driven gear 13
Diameter, both engage well.
As shown in Fig. 2 convergent nozzle 11 is set so that the interior diameter of connecting tube 10 is downward from opening in above-mentioned connecting tube 10
Successively decrease successively.
As shown in figure 1, above-mentioned support 9 is open rectangle shape, there are three, and be uniformly distributed around connecting tube 10, three
The upper end of support 9 is connected on the body of connecting tube 10, and lower end converges to the bottom of second layer water spreading disc 2, with second layer water spreading disc 2
Fixed, three middle parts of support 9 set up cross bar 14 and converge to the bottom of first layer water spreading disc 1, are fixed with first layer water spreading disc 1.
