Abstract
The invention relates to a double-end triangular thread separable spiral body type micro-nano bubble device and belongs to the technical field of general projects. At present, all thread teeth on the surfaces of a rotor and a stator which constitute a labyrinth spiral body structure are of one type in China and foreign countries. It is proved through study that although a combined tooth type thread which is composed of two types of tooth threads can achieve advantage complementation, a cavity is still of the labyrinth spiral body structure, and the machining difficulty of the labyrinth spiral body structure is high. According to the double-end triangular thread separable spiral body type micro-nano bubble device, the whole surface, of a triangular thread structure, of the rotor which serves as one component of a labyrinth spiral body is designed to be divided into two or more components according to the working condition, and the structure called a separable spiral body is obtained. The separation proportion of the separable spiral body is generally 1:2 or 2:3 and the like. The structure is easy to machine, and the operating stability of the device is ensured.
Description
Technical field the present invention relates to a kind of both-end V thread screw from the micro-nano air bubble apparatus of formula heliconid, belongs to general field of engineering technology.
Background technique is current, and the double end compound tooth type labyrinth screw pump patent No. of domestic design is: 2004100087764 its structures as shown in Figure 1.Transported medium, under motor 1 rotates, is flowed into by pump inlet flange 2 working cavity (this cavity is called " Mazy spiral body ") that the pump rotor 4 that is arranged on above pump bearing bracket 3 and pump stator 5 form, is got rid of by pump discharge flange 6.
Present Domestic forms the outward rotor of " Mazy spiral body structure " and the thread tooth type of stator surface is all a kind of thread tooth type.This patent No. is: 200410008776.4 double end compound tooth type labyrinth screw pumps, for improving flow and stability, at former " Mazy spiral body " rotor surface thread tooth type by a kind of thread tooth type, design and are made up of two kinds of thread tooth type compounds.Although research proves that the composite tooth-shape screw thread be made up of two kinds of flute profile screw threads has superiority, this cavity remains " Mazy spiral body " structure, and this structure difficulty of processing is large.By the discussion of many-side to current " Mazy spiral body structure ", think that this structure has narrow limitation, so the rotor of research and design device and the structure of stator are crucial.
Summary of the invention the object of the invention is to design a kind of both-end V thread screw from the micro-nano air bubble apparatus of formula heliconid.Be the pump rotor 4 that composite tooth-shape screw thread forms by existing Fig. 1 by integral surface, redesign as integral surface is the structure of V thread screw, then according to working condition requirement, design separates and consists of the rotor 4 of both-end V thread screw from the micro-nano air bubble apparatus Fig. 2 of formula heliconid by two or more part.Therefore medium can obtain buffering adjustment at the place of separating when carrying, so can guarantee the stability that device operates.The processing of this project organization is simple.
The present invention, by the structure of traditional " Mazy spiral body " rotor integral surface with a kind of thread tooth type, separates according to operating condition design and is made up of two or more part.So new design changes the structural type of original " Mazy spiral body " rotor, and this structure is called " from formula heliconid ".The ratio that separates from formula heliconid rotor is generally 1: 2,2: 3 etc.
Description of drawings 1 is the structural representation of prior art, and Fig. 2 is structural representation of the present invention.
Embodiment introduces both-end V thread screw from the micro-nano air bubble apparatus of formula heliconid below in conjunction with Fig. 1 and Fig. 2 accompanying drawing: 1 motor, 2 suction flanges, 3 bearing supports, 4 rotors, 5 stators, 6 outlet(discharge) flanges.
Specifically introduce content of the present invention: be composite tooth-shape worm structure by existing Fig. 1 pump rotor 4 integral surface, redesign as integral surface is a kind of worm structure of triangle flute profile, then according to duty parameter, design separates the rotor 4 being consisted of Fig. 2 by two or more part.This design can ensure that medium obtains buffering adjustment at the place of separating when carrying, and guarantees the stability that device operates thus.To be both-end V thread screws be all V thread screw flute profile from the rotor of the micro-nano air bubble apparatus of formula heliconid and stator flute profile to one embodiment of the present of invention, and it is 2: 3 that rotor threads separates ratio, and rotor and stator diameter are all 150mm composition.
Claims (1)
1. a both-end V thread screw is from the micro-nano air bubble apparatus of formula heliconid, comprise device motor, bearing support, rotor, stator, suction flange and outlet(discharge) flange, it is characterized in that device rotor surface it being all V thread screw structure, separate as two or more part forms according to operating condition design.
