Abstract

The invention relates to a double-end separated screw sewage aeration apparatus, and belongs to the field of general engineering technology. At present, maze helical structures at home and abroad are all composed of a rotor having whole screw thread and a stator. The structure works depending on screw thread tooth types. Researches prove that composite tooth type screw threads have complementary advantages and can improve stability of apparatus, but the structure is difficult to process. The whole screw thread on the rotor of the apparatus is divided and separated into two or more parts according to working conditions. A structure composed of the rotor and the stator of the apparatus is named as separated screw body. A separated ratio of the separated screw body is usually 1:1, 1:2, 1:2:1, 2:3, etc. The structure is simple in process, and has significant effects for ensuring the stability of the apparatus.

Description

Both-end is from formula spiral sewage aeration apparatus

Technical field the present invention relates to a kind of both-end from formula spiral sewage aeration apparatus, belongs to the general engineering technical field.

Background technology is present, and the both-end composite tooth-shape labyrinth spiral pump patent No. of domestic design is: 2004100087764 its structures are as shown in Figure 1.Be transferred medium and rotate down, flow into by pump inlet flange 2 in the working cavity that the pump rotor 4 that is installed in above the pump shaft bearing 3 and pump stator 5 form (this cavity is called the labyrinth spirochete), through 6 eliminatings of pump discharge flange at motor 1.

This both-end composite tooth-shape labyrinth spiral pump is to rely on thread tooth type work, on pump rotor 4 and pump stator 5 integral surfaces, has been covered with screw thread, and pump rotor 4 is two kinds of flute profiles, and purpose is to have complementary advantages in order to bring into play two kinds of flute profiles, improves the stability of device.

The research proof, each flute profile all has special advantages and deficiency, though the composite tooth-shape screw thread can be had complementary advantages, this structure difficulty of processing is big, so the structure of the rotor of research and design device and stator is crucial.

Summary of the invention the objective of the invention is to design a kind of both-end from formula spiral sewage aeration apparatus.On pump rotor 4 bases that existing Fig. 1 is made up of the composite tooth-shape screw thread; Whole composite tooth-shape screw threads above Fig. 1 pump rotor 4 are designed to a kind of flute profile screw thread, and design separates by two or more parts and consists of the rotor 4 of both-end from formula spiral sewage aeration apparatus Fig. 2 according to operating mode.Medium obtains the buffering adjustment in device is carried, and guarantees the stability of device running.

The labyrinth leptospira structure all is made up of screwed rotor of integral body and stator both at home and abroad at present.The present invention is with the whole screw thread above the device rotor, and design separates by two or more parts and forms according to operating mode.The structure of being made up of device rotor and stator is called from the formula spirochete.From the spirochetal proportionlity that separates of formula generally is 1: 1,1: 2,1: 2: 2,2: 3 etc.This structure processing is simple, and guarantees that the effect of device stability is remarkable.

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

Embodiment is introduced both-end from formula spiral sewage aeration apparatus below in conjunction with Fig. 1 and Fig. 2 accompanying drawing: 1 motor, 2 suction flanges, 3 chocks, 4 rotors, 5 stators, 6 discharge flanges.

Specifically introduce content of the present invention.On pump rotor 4 bases that existing Fig. 1 is made up of the composite tooth-shape screw thread, the whole composite tooth-shape screw thread above Fig. 1 pump rotor 4 is designed to a kind of flute profile screw thread, and design separates the device rotor 4 that is consisted of Fig. 2 by two or more parts according to operating mode.Medium obtains the buffering adjustment in device is carried, and guarantees the stability of device running.One embodiment of the present of invention are that to be all triangle thread flute profile, the rotor ratio of separating be that 1: 2, rotor and stator diameter are all 150mm and form to rotor and the stator flute profile of device.

Claims (1)

1. a both-end comprises device motor, chock, rotor, stator, suction flange and discharge flange from formula spiral sewage aeration apparatus, it is characterized in that the whole screw thread above the device rotor, and design separates by two or more parts and forms according to operating mode.
