Abstract
Centrifugal sprayer has a centrifugal wheel as atomizer, a liquid passage inside the wheel with outlet nozzle at one edge of the wheel, and a hollow shaft for liquid to pass. The advantages of the present invention include combined pressure spray and centrifugal spray, reduced hollow core inside the spray and automatic liquid replenishment.
Description
Atomizing is that energy flows or liquid surface in liquid, makes its fracture or separating process.According to different energy mode, known atomizing kind has centrifugal atomizing, pressure atomization, power atomizing, sound wave atomizing etc.This device belongs to centrifugal atomizing.
Existing centrifugal atomizing adopts the distortion of disk or disk as atomizer usually, provide a kind of power spraye as patent 87214860, it has a dropping liquid mouth and an atomizing disk, and soup drips on the atomizing disk from the dropping liquid mouth, and the centrifugal action when relying on atomizing disk to rotate is opened medicine liquid spray.There are two shortcomings in it:
1, spray direction: droplet along the atomizing disk edge to around scatter, hollowization is very serious.
2, the outer feed liquor of axle: need special feeding device.
Patent 87207831 adopts the rotating cup atomizers that Open Side Down, and soup moves to rim of a cup at the bottom of cup, and outwards spray at the place at rim of a cup and since soup at the bottom of the cup to the speed of rim of a cup motion much smaller than rotary speed, soup is difficult to spray forward.
In order to solve the problem of soup to the atomizing disk surface of carrying, the centrifugal pump that patent 88220882 adopts a direct current micro machine to drive is delivered to soup on the atomizing disk from the liquid barrel pump.To increase device, consumed energy so inevitably.
The objective of the invention is to alleviate or eliminate the spraying hollowization, make liquid tapered forward the spray.And do not need special feeding device.
This device is made up of centrifugal wheel, rotating shaft and bearing thereof, transmission mechanism, frame, and centrifugal wheel is fixed on an end of rotating shaft, and transmission mechanism is generally a motor, and it drives rotating shaft and centrifugal wheel rotates together, and bearing fixing is on frame.
This rotating shaft is a hollow pipe, establish one or more fluid passage that extends from middle mind-set edge in the centrifugal wheel, this passage links to each other with the hollow of hollow rotating shaft, its outlet is nozzle, be positioned at the centrifugal wheel end face one end place that keeps to the side, the centerline direction of nozzle is parallel with the axis direction of rotating shaft or become one less than 90 degree angles, fluid passage in hollow rotating shaft, the centrifugal wheel, nozzle constitute the fluid passage of a sealing, liquid enters from hollow rotating shaft one end, in centrifugal wheel,, spray from nozzle by centrifugal pressurization.
Special circumstances, when the nozzle direction was parallel with the shaft axis direction, liquid internal pressure power made liquid spray along axis direction, but centrifugal force makes the tangential direction of liquid along the centrifugal wheel edge, and as not considering friction factor, the two is equal substantially.Thereby the liquid emission direction becomes miter angle with axis direction, and general effect is that liquid sprays forward with the conical surface.
This device also can be established a feed tube, is positioned at a not fixing end of centrifugal wheel of rotating shaft, between feed tube and the rotating shaft seal is arranged, and realizes the movable sealing of the two.Then when liquid after nozzle ejection, siphonage can make liquid constantly be replenished.
Usually the transmission mechanism of this device is a motor, and motor is connected with shaft joint alternate manner alive such as gear etc. with the rotating shaft of centrifugal wheel.For making structure simpler, it is one that the rotating shaft of motor can contain two with the rotating shaft of centrifugal wheel, i.e. the rotating shaft of motor is a hollow pipe, and rotating shaft is to extending vertically, and an end is centrifugal wheel fixedly, as the rotating shaft of centrifugal wheel; The other end is as inlet.
Nozzle can be very simple, and an aperture also can be complicated shape in this way, as before ejection a cylindrical little cavity being arranged, there is a pillar centre of cavity, and liquid tangentially enters from a side of cavity, rotation at a high speed sprays from aperture then in cavity.So just combine two kinds of atomization methods of pressure atomization and centrifugal atomizing, make atomizing effect better.Before liquid ejection, it is rotated in a loculus body, also has a lot of ways, as adopt two night the road, they all tangentially enter little cavity, two the relative cavity of point of penetration center symmetries but direction is opposite.
The radial line angular separation of supposing nozzle direction and runner is α, with the tangential direction angle β of runner, with the axis direction angle γ of rotating shaft, special circumstances are when α=90 degree, β=90 degree, when γ=0 is spent, when then liquid sprayed at the nozzle place, its center position became 45 degree with direction of principal axis.Change three angles, can change the shape of spraying.As make α=90 degree, β＜90 degree, γ=0 degree, and then runner is sprayed when a direction is rotated and is concentrated to axis direction, and spraying is more dispersed when rotating in opposite direction.Select suitable angle, can eliminate hollowization of spraying.
Advantage of the present invention is:
A combines pressure atomization and centrifugal atomizing, thereby atomizing effect is good.
B, simple in structure: centrifugal wheel is a pump, also is atomizer simultaneously.
C, the efficient height: centrifugal wheel turns round in air, only limits to liquid road in the centrifugal wheel with contacting of liquid, and it is very little to rub, and axle water inlet simultaneously makes that sealing is very simple, and frictional dissipation is also very little.
Accompanying drawing 1 is embodiment.
