Abstract

The invention relates to a single-ended triangular thread split-type spiral body micro-nano bubble device, and belongs to the technical field of general engineering. At present, thread tooth shapes on the surfaces of rotors and stators constituting a 'maze spiral body structure' at home and abroad are all of a thread tooth shape. Study have proved that a compound tooth type thread composed of two kinds of tooth type threads can complement the advantages of each other, but a cavity is still of the 'maze spiral body' structure, and processing of the structure is difficult. According to the single-ended triangular thread split-type spiral body micro-nano bubble device, a triangular thread structure is applied to the surfaces of all the rotors which participate in constituting the 'maze spiral body', the rotors composed of two or more parts are designed to be disjoined according to the working condition, and the structure is called a 'split-type spiral body'. Generally, the disjoining ratio of the split-type spiral body is 1:1, 1:2 and the like. The structure is easy to process, and the stability of the device operation is ensured.

Description

Single-ended V thread screw is from the micro-nano air bubble apparatus of formula heliconid

Technical field the present invention relates to a kind of single-ended V thread screw from the micro-nano air bubble apparatus of formula heliconid, belongs to general field of engineering technology.

The single end composite tooth type labyrinth screw pump patent No. of the current domestic design of background technique is: 200420007044.9 its structures as shown in Figure 1.Transported medium, under motor 1 rotates, is flowed in working cavity that the pump rotor 4 that is arranged on above pump bearing bracket 3 and pump stator 5 form (this cavity is called " Mazy spiral body ") by pump inlet flange 2, 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: 200420007044.9 single end composite tooth type labyrinth screw pumps, for improving pump duty and stability, by 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 flute profile 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 a kind of single-ended V thread screw of design 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 single-ended V thread screw from the micro-nano air bubble apparatus Fig. 2 of formula heliconid by two or more part.Now the rotor 4 of Fig. 2 can obtain buffering adjustment at the place of separating when fed sheet of a media, it is hereby ensured 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 proportionate relationship that separates from formula heliconid rotor is generally 1: 1 or 1: 2 etc.

Description of drawings 1 is the structural representation of prior art, and Fig. 2 is structural representation of the present invention.

Embodiment introduces single-ended V thread screw from the micro-nano air bubble apparatus of formula heliconid below in conjunction with Fig. 1 and Fig. 2 accompanying drawing: motor 1, suction flange 2, bearing support 3, rotor 4, stator 5, outlet(discharge) flange 6.

Specifically introduce content of the present invention.Be the pump rotor 4 that composite tooth-shape screw thread forms by existing Fig. 1 by 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.Medium can obtain buffering adjustment at the place of separating when rotor 4 is carried, and guarantee the stability that device operates.To be single-ended 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 1: 2 that rotor threads separates ratio, and rotor and stator diameter are all 70mm composition.

Claims

1. a single-ended 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.
