Abstract

The invention relates to a double-ended trapezoidal thread separated type spiral body micro-nano bubble device, and belongs to the technical field of general engineering. The surfaces of rotors and stators forming 'maze spiral body structures' at home and abroad at present only adopt one thread tooth type. Research proves that even if a compound tooth type thread adopting two types of tooth type thread has complementary advantages, a cavity still adopts the 'maze spiral body' structure, and the processing of the structure is very difficult. According to the invention, the surface of the rotor forming the 'maze spiral body'completely adopts the trapezoidal thread structure, and is separated into two or more parts according to working condition design; the structure is named as a 'separated type spiral body'; generally, the separating proportion of the separated type spiral body is 1:2, 2:3, and the like; the structure is simple in processing, and the stability of the device during running is ensured.

Description

Both-end trapezoidal thread is from the micro-nano air bubble apparatus of formula heliconid

Technical field the present invention relates to a kind of both-end trapezoidal thread 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 trapezoidal thread 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 trapezoidal thread, then according to working condition requirement, design separates and consists of the rotor 4 of both-end trapezoidal thread 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 trapezoidal thread 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 trapezoidal 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 trapezoidal threads be all trapezoidal thread 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 200mm composition.
