Abstract
The invention provides a liquid level self-adaptive defoaming paddle for the technical field of stirring. The liquid level self-adaptive defoaming paddle comprises a hub sleeved on a stirring shaft, driving keys for circumferentially positioning the hub, functioning in rotating driving and allowing the hub to freely slide up and down within a certain range in the axial direction, a radial support rod fixed with the hub and a defoaming paddle fixed on the support rod, wherein an annular buoyancy device is arranged under a stirring paddle and fixedly connected with the defoaming paddle through a fixing device. The self-adaptive defoaming paddle is capable of realizing self-adaption of the defoaming paddle to the liquid level height so that the defoaming paddle is always in the optimal position required for breaking foam formed on the liquid level of a stirring medium, and especially applicable to the stirring working condition of rising-falling fluctuation of the liquid level of the stirring medium during working.
Description
Technical field
The invention belongs to stirring technique field, the froth breaking oar specifically using on mixing plant.
Background technology
Froth breaking oar is widely used in the mixing plant of fermentation industry, and its effect is to destroy the foam covering on agitated medium liquid level, controls appearance or the increase of agitated medium liquid level foam.Froth breaking oar is mainly axial restraint type at present, in the time that technological requirement changes agitated medium liquid level, need by manually adjusting the setting height(from bottom) of froth breaking oar on shaft, this is complex operation not only, also very inconvenient, when froth breaking oar is too high, can affect defoaming effect, when too low, can produce extra power consumption, even cause the super stream of equipment motor.
Summary of the invention
The object of the invention is to design a kind of liquid level self-adaptation type froth breaking oar, can, according to the fluctuation up and down of agitated medium liquid level, automatically adjust its height and position on shaft, thereby reach best defoaming effect.
The present invention solves the problems of the technologies described above adopted technical scheme: the liquid level self-adaptation type froth breaking oar of invention, comprise the wheel hub that is sleeved on shaft, play rotary drive effect simultaneously and allow its driving key freely sliding up and down, and the radial strut that is fixed together of wheel hub and be fixed on the froth breaking blade on support bar in axial certain limit for circumferential location wheel hub, being positioned at stirrer paddle below has annular buoyant device, and annular buoyant device is fixedly connected with froth breaking blade by fixture.When work, shaft rotarily drives liquid level self-adaptation type froth breaking oar rotary work, froth breaking blade on self-adaptation type froth breaking oar can destroy the foam that agitated medium liquid level forms in time, in the time that agitated medium liquid level raises or reduce, because self-adaptation type froth breaking oar can freely slide up and down within the specific limits on shaft, so the Action of Gravity Field of self-adaptation type froth breaking oar itself is the two balance result of the buoyancy of incidental annular buoyant device in agitated medium with it, just in time guarantee the needed optimum position of foam that liquid level self-adaptation type froth breaking oar forms in destroying agitated medium liquid level all the time, namely liquid level self-adaptation type froth breaking oar has adaptivity to liquid level.
The invention has the beneficial effects as follows: realize the self adaptation of froth breaking oar to liquid level, make its needed optimum position of foam forming in destroying agitated medium liquid level all the time, during for work, agitated medium liquid level has the stirring operating mode particularly suitable of lifting fluctuation.
In order to save cost and to reduce rotational resistance, annular buoyant device is cavity ring body, and open section is preferably circle, and annular buoyant device axial symmetry is installed, and its external diameter is not more than support bar or the rotating diameter of froth breaking blade centered by shaft.
Accompanying drawing explanation
Fig. 1 is liquid level self-adaptation type froth breaking paddle structure schematic diagram.
The specific embodiment
Fig. 1 is an embodiment of liquid level self-adaptation type froth breaking oar, and liquid level self-adaptation type froth breaking oar comprises wheel hub 1, support bar 2, froth breaking blade 3, fixture 4, buoyant device 5 and driving key 7.Liquid level self-adaptation type froth breaking oar is sleeved on shaft 6 and is coordinated driving key 7 to realize transmission by the keyway on the keyway on wheel hub 1 and shaft 6 by wheel hub 1, wheel hub 1 is not located on shaft 6, only come restrictive axial scope of activities and circumferentially transmission by the bulge-structure on driving key 7, froth breaking blade 3 is connected with wheel hub 1 by support bar 2, buoyant device 5 is connected with froth breaking blade 3 by fixture 4, buoyant device 5 is designed to the hollow annular structure using shaft axis as center line, while making its work, do not affect flow field, can produce larger liquid displaced volume simultaneously, realize the gravity that the buoyancy producing by buoyant device 5 carrys out balance liquid level self-adaptation type froth breaking oar in liquid, make the froth breaking blade 3 of snakelike grizzly bar shape all the time near liquid level, realize the self adaptation that froth breaking oar changes liquid level, thereby reach best defoaming effect.
