Abstract
The utility model discloses a Venturi ejector comprising a Venturi ejector body which is provided with a turbulent flow device used for leading the ejection liquid and the self-absorption medium to be fully mixed. The three kinds of Venturi ejection pipes of the Venturi ejector can effectively increase the turbulent flow of the mixture to lead the mixture to be highly mixed and the turbulent flow to be enhanced, improve the contact area and the physical and chemical properties of all the mediums in the mixture, and meet the process needs.
Description
Technical field
The utility model relates to a kind of venturi-type eductors, relates in particular to a kind of venturi-type eductors of turbulent flow type.
Background technology
Thereby in Chemical Manufacture, usually use Venturi tube and inhale emanate body or liquid from air absorbing body or liquid, the medium that Venturi tube injector suction commonly used is penetrated siphons away the air in the pipe when the nozzle trunnion sprays in collapsible tube, thereby make induction chamber produce negative pressure, by other media of negative pressure self-priming, the medium that sucks and the medium of former injection be the directly straight tube ejection from being connected with anemostat behind mixing tube, anemostat, without any the setting that increases turbulent flow, the mixture of injection medium and self-priming medium is realized mixing by the speed of ejection fully in exit portion.Some arts demand fully mixes the medium of self-priming and the liquid of injection, and the big more mixing of turbulent flow is abundant more good more, and former venturi-type eductors can not satisfy the mixing needs.
The utility model content
Goal of the invention: at the deficiencies in the prior art, the purpose of this utility model provides a kind of venturi-type eductors of turbulent flow type, to produce powerful turbulent effect, satisfies injection liquid and the self-priming medium fully mixes.
Technical scheme: in order to realize the foregoing invention purpose, the technical solution adopted in the utility model is:
A kind of venturi-type eductors comprises the venturi-type eductors body, it is characterized in that: be provided with on described venturi-type eductors body and be used to satisfy injection liquid and the well-mixed turbulent device of self-priming medium.
Described turbulent device is the hole that is arranged on the Venturi tube exit position.Increase for realizing the effect of turbulent flow, the utility model is in cloth hole, Venturi tube exit position, and liquid is through the Venturi tube injection, the self-priming medium, and mixture scatters from the mouth of pipe and aperture and comes when outlet is sprayed, thereby increase turbulent flow mixture is fully mixed.
Described turbulent device can be provided with the hole for being arranged on the baffle plate of Venturi tube exit position on baffle plate.Connect the baffle plate that the centre is porose in the Venturi tube exit position with four round steel, liquid is through the Venturi tube injection, and the self-priming medium impacts the baffle plate that has mesopore when outlet is sprayed, mixture is sputter immediately, and its turbulence intensity can also be adjusted by the angle of controllable register.
Described turbulent device can also be for being arranged on the elbow of Venturi tube exit position.At Venturi tube exit position tape splicing the elbow of certain angle is arranged, liquid is through the Venturi tube injection, and the self-priming medium makes mixture flow along certain angle when the elbow outlet is sprayed, thereby increases turbulent effect.
Beneficial effect: three kinds of venturi playpipes of the present utility model can effectively increase the turbulent flow of mixture, the mixture height is mixed, and turbulent flow is strengthened, and has improved the contact area of each medium in the mixture, improve the physical and chemical performance of each medium simultaneously, satisfied process requirements.
Description of drawings
Fig. 1 is first kind of structural representation of venturi-type eductors of the present utility model.
Fig. 2 is second kind of structural representation of venturi-type eductors of the present utility model.
Fig. 3 is the third structural representation of venturi-type eductors of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further explained.
As shown in Figure 1, be first kind of structure of venturi-type eductors of the present utility model.In cloth hole, Venturi tube exit position 3, liquid 1 is through the Venturi tube injection, self-priming medium 2, and mixture scatters from the mouth of pipe and hole 3 and comes when outlet is sprayed, thereby increase turbulent flow mixture is fully mixed.
As shown in Figure 2, be second kind of structure of venturi-type eductors of the present utility model.Connect the baffle plate 4 that the centre is porose in the Venturi tube exit position with four round steel 5, liquid 1 is through the Venturi tube injection, self-priming medium 2, when spraying, outlet impacts the baffle plate 4 that has mesopore, mixture is sputter immediately, its turbulence intensity can also be adjusted by the angle of controllable register 4, for example 30 °, 45 ° and 60 ° or the like.
As shown in Figure 3, the third structure of venturi-type eductors of the present utility model.At Venturi tube exit position tape splicing the elbow 6 of certain angle is arranged, liquid 1 is through the Venturi tube injection, and self-priming medium 2 makes mixture flow along certain angle when elbow 6 outlets are sprayed, thereby increases turbulent effect.The angle of elbow 6 can be provided with arbitrarily, and angle commonly used has 30 °, 45 ° and 60 ° or the like.
Three kinds of venturi playpipes of the present utility model can effectively increase the turbulent flow of mixture, and the mixture height is mixed, and turbulent flow is strengthened, and has improved the contact area of each medium in the mixture, has improved the physical and chemical performance of each medium simultaneously, has satisfied process requirements.
